Abstract

Objective To pilot and feasibility-test supervised final year undergraduate pharmacy

student-led medication reviews for patients with diabetes to enable definitive trial

design.

Method Third year pharmacy students were recruited from one UK School of

Pharmacy and trained to review patient’s medical records and provide face-to-face

consultations under supervision whilst situated within the patient’s medical practice.

Patients with type 2 diabetes were recruited by postal invitation letter from their

medical practice and randomised via automated system to intervention or usual care.

Diabetes-related clinical data, quality of life, patient reported beliefs, adherence and

satisfaction with medicines information (SIMS) were collected with validated tools at

baseline and six months post-intervention. The process for collecting resource

utilisation data was tested. Stakeholder meetings were held before and after

intervention to develop study design and learn from its implementation. Recruitment

and attrition rates were determined plus the quality and completeness of outcome

data. Power calculations for a definitive trial were performed on the different

outcome measures to identify the most appropriate primary outcome measure.

Results 792 patients were identified as eligible from five medical practices. 133

(16.8%) were recruited and randomised to control (n=66) or usual care (n=67). 32

students provided the complete intervention to 58 patients. Initial analysis showed

potential for impact for some outcomes including HbA1c, quality of life and

satisfaction with information (SIMS). The intervention was found to be feasible and

acceptable to patients. The pilot and feasibility study enabled the design of a future

full RCT.

Conclusion Student and patient recruitment are possible. The intervention was well

received and demonstrated potential benefits. Whilst the intervention was relatively

inexpensive and provided an experiential learning opportunity for pharmacy

students, its cost-effectiveness remains to be determined.

Strengths and limitations of this study

• The study followed recommendations published by the Medical Research

Council[1] for implementation of feasibility and pilot studies.

• The intervention was developed with significant stakeholder involvement, a

range of primary outcome measures were tested for suitability and the

process for collecting resource utilisation data was identified.

• Self-selection bias was found within those students who consented to

participate

• The trial was unblinded with the service providers, patients and researchers

all aware of group allocation and intervention content

• The large number of statistical tests carried out creates the possibility that

findings could be false positives and, as this was a pilot and feasibility study, it

had low power and could have failed to detect small to moderate sized

effects.

Introduction

It is estimated that preventable harm from medicines costs the NHS in England £750

million per year[2]. A systematic review in 2009, based on UK research, estimated

that only between 4% and 21% of patients achieved the optimum benefit from their

medication[3]. A systematic review of publications between 1966 and 1999 reported

the prevalence of preventable drug-related admissions to hospital as 4.3%[4].

Additionally, patients not taking their medicines as agreed with the prescriber has

been reported to cost the UK NHS an estimated half a billion pounds a year[5].

Consequently, interventions designed to reduce adverse drug events and improve

patient medicines-taking behaviours are required.

Medication review (MR) has been defined as 'a structured, critical examination of a

patient's medicines with the objective of reaching an agreement with the patient

about treatment, optimising the impact of medicines, minimising the number of

medication-related problems in addition to reducing waste'[6]. MR in the UK was

described as operating at four different levels[6], with the key component of Level 3

medication reviews being the involvement of the patient whilst accessing their

medical records.

Pharmacist-led medication reviews have been shown to reduce costs associated

with unnecessary prescribing of medication whilst potentially providing patient

benefit[7]. However, UK based research utilising pharmacists to provide medication

reviews has in the past found a counter-intuitive increase in hospitalisation[8], with

one partial explanation being the didactic nature of the pharmacist communication[9

10]. Effective communication skills are necessary to improve patient behaviours

both in terms of lifestyle[11] and medication taking[12]. Consequently, models of

consultation behaviour have been developed and are commonly used within the

education of healthcare professionals [13 14].

Whilst UK pharmacy graduates develop expertise in the pharmacology and

therapeutics of medicines, undergraduate training currently lacks significant patient

contact. This provides limited opportunities for the development of clinical and

communication skills during training[15]. In contrast, medical students routinely work

with patients during their undergraduate training[16] and undergraduate students

within Schools of Dentistry and Optometry provide services to patients under the

supervision of clinical tutors to improve both their clinical and communication

skills[17 18].

Involvement of pharmacy students in the provision of healthcare services in other

countries has been reported[19 20] with very good prescriber acceptance of student

recommendations[21]. However, pharmacy student provision of medication review

to patients in the UK, with the dual aims of demonstrating patient benefit and

improving student communication and clinical skills, has not been tested. For new

models of care to be adopted, it is necessary to demonstrate that they are likely to

be cost-effective. There is currently no evidence of this for the provision of

pharmacy student-led medication review services.

Two and a half million of the UK population currently have type 2 diabetes with an

estimated direct cost to the healthcare system of £8.8 billion/annum[22].

Pharmacist-led medication reviews for patients with diabetes have demonstrated

significant reductions in blood pressure[23 24] and HbA1c[25 26], both of which are

necessary to reduce long-term morbidity[27]. Approximately 60% of patients are

achieving the target HbA1c below 7.5% (59mmol/mol) [28]. Due to the availability of

clearly defined national treatment guidelines[29-31] and increasing numbers of

patients with type 2 diabetes, medication review for patients with diabetes is a

service which pharmacy students may be able to usefully provide.

A pilot and feasibility study was, therefore, undertaken in line with national guidance

for the evaluation of complex interventions[1], to determine: recruitment and attrition

rates for students and patients; describe the suitability of using student volunteers;

test data collection for a future cost-effectiveness analysis; describe the potential

effects of the intervention; identify the most suitable primary outcome measure; and

estimate variance around this to enable a future trial to be effectively powered.

Method

Ethical approval was obtained from the UK health system (Cambridge 3 ethics

committee – Jan 2010) and NHS management permission was obtained from NHS

South Norfolk CCG (formerly NHS Norfolk and Waveney PCT) prior to

commencement of the study. Ethics ref no. 10/H0306/77.

University of East Anglia ethical approval was obtained to permit collection of student

examination results.

ISRCTN No 26445805 was obtained retrospectively rather than prospectively due to

misinterpretation of an NIHR email stating that “NIHR Clinical Research Network

(CRN) Coordinating Centre has developed a process which enables automatic

registration of all new NIHR Clinical Research Network Portfolio studies via the

Portfolio database”. We did not notice that they provided details of ISRCTN

registration via UKCRN Portfolio database later in the same email.

Student recruitment and preparation

All 84 third year pharmacy students from one UK school of pharmacy were invited to

participate in June 2011. The intervention was timetabled to occur during the final

year (fourth) of their undergraduate studies. Informed consent was obtained from

students agreeing to participate. A reserve list was created and used to resolve any

anticipated drop-out caused by the additional workload created by the study within

the students’ final year.

Standard education process already included basic training in consultation skills,

data governance, and observation of a primary care doctor in practice. In addition,

participating ‘study students’ undertook four half-day training sessions comprising

the following:

• use of medical practice information systems using ‘dummy’ patient records,

• revision of ‘pharmaceutical care planning’ using a care plan designed to enable

recording of patient details and also to provide a guide to their consultations,

• a consultation skills workshop which included utilising dummy primary care

patient records and training in basic behaviour change counselling,

• two medicines-related consultations with pre-prepared and scripted professional

role-play actor ‘patients’, following which individual and group feedback was

provided.

All student preparative training was undertaken at the University of East Anglia

(UEA), apart from training in the use of computerised medical records which was

provided by NHS Norfolk and Waveney.

Examination results for students (both participating and non-participating) were

obtained at the end of year three (i.e. shortly after recruitment) to identify potential

student self-selection bias.

Medical practice and patient recruitment

Five Norfolk-based medical practices were purposively recruited by NHS Norfolk and

Waveney. The inclusion criteria were:

• pharmacist working as a prescribing advisor within the practice,

• using the SystmOne IT medical record system,

• over 200 patients registered with type 2 diabetes.

Presence of a pharmacist was required to enable student supervision; the same IT

system to facilitate student training. A target number of patients was required to

increase the opportunity for meeting recruitment targets.

Patient recruitment

Patients in each medical practice who met the inclusion/exclusion criteria were

posted a letter from the practice asking them to participate in the study:

Inclusion criteria

• prescribed non-insulin medication for type 2 diabetes mellitus for at least two

years, to increase likelihood that therapy is stabilised.

Exclusion criteria

• deemed unsuitable for inclusion in the trial by their GP for any reason,

• enrolled into other clinical trials,

• diagnosed with a terminal illness.

All recruited patients were randomised to intervention or control (standard care)

using an automated randomisation system which ensured concealed allocation.

Randomisation was undertaken in blocks of four to maximise equality of group size.

All researchers and clinical staff involved with generating outcome data were blind to

participant allocation.

As a pilot study it was decided to test a number of potential primary outcome

measures, with results enabling a decision as to which measure to use in a future

study:

• HbA1c,

• blood pressure,

• lipid profile.

Secondary outcome measures were:

• health related quality of life (EQ-5D),

• satisfaction with information about medicines (SIMS)[32],

• medication adherence (MARS)[33],

• patient’s beliefs about medicines (The Beliefs and Medicines

Questionnaire)[34],

• diabetes treatment satisfaction questionnaire (DTSQ)[35].

Level 2 medication reviews (i.e. using patient records only) were undertaken by

students between November 2011 and February 2012; whilst student-led patient

consultations (Level 3 medication reviews) took place between December 2011 and

March 2012.

Sample size justification

As a pilot study it was not appropriate to power the study. Consequently, we

determined the likely precision of the study for estimating the effect of the

intervention on the continuous endpoints by estimating the expected value of the

half-width of the 95% confidence interval around the difference in means between

the intervention and control groups. Assuming 80 patients in each group and a

standard deviation of 1.5% in the primary outcome variable of HbA1c, then the

estimate from this pilot study of the effect of the intervention on this endpoint would

be within 0.5% of its ‘true’ value. An observed difference in group means >0.5%

(e.g. HbA1c 7.0% compared to 7.5%) would be statistically significant.

From each of the five practices 32 patients were, therefore, required, providing 160

in total (80 in each of intervention and control arms). It was planned that each

student would be allocated two patients in the intervention arm for review and

consequently forty students were required.

Baseline data

Both intervention and control participants were posted a questionnaire after the

researcher had received their completed consent, comprising the secondary

outcome measures, which included an additional question asking whether they used

a medicines compliance aid.

The patient notes within the medical practice were investigated to obtain:

• demographic data,

• most recent results prior to recruitment for HbA1C, blood pressure and lipid

profile,

• medication utilisation (cost of all prescriptions issued for each patient for a

baseline period of three months prior to intervention

• NHS resource utilisation calculated as cost (using standard NHS staff cost) of

all NHS contact for a baseline period of three months prior to intervention

The last two items were included to determine the feasibility of collecting data for a

future cost-effectiveness analysis within a randomised controlled trial.

Intervention

At the patient’s medical practice, students were randomised to work in pairs. This

provided additional support and shared learning in addition to the wider clinical

experience provided by access to additional patient records. Each pair, therefore,

worked to undertake Level 2 medication reviews for four intervention patients under

the supervision of a PCT pharmacist. Students compared prescribing with national

guidance [29-31] and created individualised pharmaceutical care plans (PCP) on a

pre-defined pro-forma.

PCPs included demographics, allergies, special needs, lifestyle [e.g. diet and

smoking status], relevant medical history, medication adherence, pharmacy use,

current prescribed medication, over the counter, herbal and homeopathic preparation

use and any care issues identified. After discussion and agreement with the

supervising pharmacist, care issues identified were fed back on a custom-designed

form, to either the patient’s specialist diabetes nurse or medical practitioner who then

decided on the final action.

Patients were then offered a range of flexible dates and times, to maximise

participation of a meeting between each student and an individual patient.

The consultation (Level 3 medication review) took place at the patient’s medical

practice and was separated by at least two weeks from the Level 2 review to enable

the doctor or nurse to rectify or question any problems identified by students, prior to

the subsequent student-led consultation. As planned in the protocol, each student

provided two patient consultations which had no time limit imposed on their duration.

Follow-up

Six months post-intervention, a questionnaire was posted to both intervention and

control participants. The questionnaire was identical to the baseline version but with

an additional question regarding frequency of community pharmacy service

utilisation. Intervention participants were also asked to report any change in

utilisation of community pharmacists following the student consultation to identify any

change in attitude to, or view of, community pharmacists. The same data as

baseline were collected from the medical practice including: HbA1c, blood pressure

and lipid profile at six months post-intervention (with a cut-off point of one year); and

medication and resource utilisation for the six month period post intervention.

Stakeholder meetings

Stakeholder meetings were held with patients, students, primary care pharmacists

and medical practice staff both before and after the intervention. Interested

individuals from each group were recruited prior to the study’s implementation to

Data analysis

The variance in the difference between each co-primary outcome measure between

groups was undertaken on an intention-to-treat basis using independent t-tests and

Mann-Whitney U tests, as appropriate, followed by a regression analysis adjusting

results at follow-up for values at baseline for key biological outcomes (HbA1C, total

cholesterol, and blood pressure. The patient recruitment rate and the medicine-

related consultation uptake rate, were both determined. SPSS version 22 was used

for analysis.

Stakeholder meeting analysis

Simple content analysis which proceeded to identify all themes, as recognised by the

researcher, was undertaken for development meetings with the main learning points

recorded for action as appropriate. Review meeting analysis followed the general

principles of the framework approach[36]. There was no independent analysis of the

data. Nvivo 10 was used to facilitate analysis.

Health economics analysis

As a pilot study we report completion rates for resource use items and the EQ-5D.

Additionally, unit costs[37] were extracted in order to enable the cost of the

intervention to be estimated.

Results

Figure 1 summarises the patient recruitment process which achieved a 16.8%

consent rate. Recruitment rates within the five medical practices were 17.2%,

19.6%, 20.1%, 18.5% and 9.4%. The first two practices recruited in time to enable

students to complete medication reviews before Christmas 2011. The other three

practices recruited later. This resulted in medication reviews in one practice being

undertaken in March 2012. Of the 67 patients randomised to intervention, 91.0%

remained in the study prior to the student-led medication review with 100% of those

agreeing to an appointment with a student for a consultation. Of these, three (4.9%)

failed to attend the consultation.

Figure 1 summarises the patient recruitment process. Of 792 patients approached by

letter, 133 (16.8%) consented and were randomised to control (n=66) or intervention

(n=67). Recruitment rates within the five medical practices were 18.5%, 19.6%,

19.8%, 20.1% and 9.45%. Of patients (61) remaining in the study prior to the

student-led medication review 100% agreed to an appointment with a student for a

Figure 2 provides a summary of the flow of students at each stage of the study. Of

the 47 students who volunteered and completed a consent form, 12.75% were male.

The first 40 students volunteering were recruited with the remaining seven forming

the reserve list, to be used if recruited students left the study. Patient consultations

were undertaken by 32 of the 47 (68%); however, of these six only undertook one

consultation due to patient numbers. Mean (SD) exam scores at end of year three

(at recruitment) for participating and non-participating students were 62.80 (7.91)

and 58.91 (7.98), respectively. Academic performance of participating students was

significantly better than non-participating students at the point of recruitment (p<0.05,

t-test).

For peer review only

Twenty five (55.5%) patients who had met a student for a Level 3 medication review

and responded to this question, agreed or strongly agreed that they were far more

likely to speak to a pharmacist about their medicines or their health following the

medication review.

It was calculated that for a full RCT to demonstrate an effect of 5.5mmol/mol on

HbA1c, 159 patients would be required in each group for 80% power, and 214

patients per group to have 90% power. Data utilised for sample size analysis are

presented in Table 3.

Health economics analysis

The mean per participant cost of the intervention was £164.41; Table 5 provides a

breakdown of the component parts. We used different versions of the EQ-5D (the

five level version[38] at baseline and the three level[39] at follow-up) to assess

whether completion rates differed according to the number of levels. The response

rates were slightly higher for the EQ-5D-3L and the mean change in EQ-5D score

was slightly higher for the intervention arm (see Tables 1 and 2). Complete cost and

effect data were available for 72 participants (54.1% of the sample).

Stakeholder meetings

All stakeholder groups supported the testing of the idea. There was agreement that

student-led consultations should take place at the medical practice of each patient

rather than at the university; should not be time-limited; and should be supervised.

Post-intervention stakeholder groups agreed that the experience had been generally

positive, had provided both student and patient benefit, and raised awareness of the

role of pharmacists.

Discussion This pilot study has demonstrated the acceptability and practicality of pharmacy

students providing full medication review to patients with type 2 diabetes under

supervision. All stakeholder groups displayed support for the concept, with patients

also displaying a willingness to participate in a subsequent RCT. Medical practices

were purposively selected, and no problems were experienced with recruitment,

though recruitment rates were relatively low (17%). Nevertheless, future recruitment

for a full RCT would be possible. Importantly, there was also a very low patient

dropout rate (<10%). Potential patient benefit was also identified within some of the

outcome measures. The results therefore provide evidence that within an RCT,

sufficient patients could be expected to agree to attend for a medication related

consultation.

As this was a pilot study and had small participant numbers we did not expect to

demonstrate significant changes in our outcome measures. Students were

volunteers and may not represent a full population of undergraduate pharmacy

students. All participating medical practices were requested to commence

recruitment at the same time; however, results demonstrate patient recruitment

proceeding over a period of greater than four months, resulting in logistical issues

within the project. Ethical reasons required recruitment to be initiated via the medical

practices, but results suggest that closer communication and support may be

required between the researcher and medical practices to facilitate earlier

recruitment. Written appointment information may aid patient attendance and

prevent the small number of patients failing to attend due to forgetfulness. The large

number of statistical tests carried out, increased the likelihood of false positive

findings. Conversely, as a pilot and feasibility study with limited sample size there is

an increased likelihood of false negatives.

Whilst student willingness to participate was high, pressures of concurrent timetabled

course work and a lack of confidence in ability to perform the consultation resulted in

significant drop out during the progress of the study. Integration of the service into

the curriculum did not result in drop out from similar non-UK studies[19 20].

Participating students were volunteers and, therefore, self-selecting. Given that they

were, on average, academically superior when compared to non-participating

students, they would potentially have performed better than non-participants during a

student-led consultation. Most studies do not mention this effect and any future

study utilising volunteer students should recognise and allow for it[19 40-43]. The

quality of medicines information given to patients is likely to affect each patient’s

perception of whether it has met their needs and if they are satisfied with the

information provided[32]. It is reasonable to speculate that repetition of information

over a period of years to patients with a long-term condition would have resulted in a

greater understanding of and, therefore, satisfaction with information about their

medicines. This may have reduced the ability to improve scores for many of the

individual questions. Whilst higher scores for SIMS is theoretically a predictor for

better adherence (MARS)[32] no improvement in adherence was observed. The

relatively high proportion of patients who reported using medication compliance aids

prior to the intervention might have reduced the potential for the intervention to

improve adherence further. Adherence, beliefs about medication, satisfaction with

diabetes treatment and quality of life all displayed a change in the direction which

favours the intervention, all of which support a full study going ahead. No evidence

is available to definitively explain the change in blood pressure seen in the control

group and reasons for this would only be speculative, but it may simply have been a

chance finding.

Results demonstrate that HbA1c would appear to be a sensible primary outcome

measure for a future study. A sample size of 214 patients per group (428 in total)

would be required to demonstrate a 90% power. This would equate to 107 students

(two patient consultations per student), which is achievable within a full RCT

undertaken over more than one school of pharmacy. However, recent NICE

guidance recommends the utilisation of a cardiac risk measure (QRisk2)[44-46]

which represents a compilation of clinical data. Insufficient data are available to

calculate a sample size for QRisk2, therefore, the pragmatic decision would be to

utilise a primary outcome measure of HbA1c with QRisk2 potentially utilised as a

secondary outcome measure.

Evidence does not exist in the UK to support the training of undergraduate pharmacy

students when undertaking activities with real patients, although examples exist

outside the UK[19 20 42]. This study does not provide definitive evidence for this, but

does provide support for a future definitive RCT to test this hypothesis.

With a known patient recruitment rate and low dropout rate this demonstrates that if

the same protocol were to be utilised for a future RCT then sufficient numbers of

patients can be expected to be recruited and retained. Medical practices were

chosen because they all used the same software system for electronic medical

records, as this would facilitate student training, however, utilising additional systems

would increase the number of GP practices available for recruitment. Changes may

be warranted to patient selection criteria, as recruitment of patients who are not yet

clinically stabilised may be more receptive to information regarding their medicines.

NICE CG66[44] recommends a blood pressure target level of <140/80mmHg for

most people with type 2 diabetes, and <130/80mmHg for those at more particular

risk. The latter group includes people with raised albumin excretion rate (AER)

(microalbuminuria or worse), eGFR <60ml/min/1.73m2, those with retinopathy, and

those with prior stroke or transient ischaemic attack (TIA). Data to enable such

differentiation was not obtained within the pilot study and should be included in the

design of a future definitive RCT. Provision of opportunities for students to

undertake more than two consultations in future studies may demonstrate further

student and patient benefit. Results provide evidence that within an RCT, sufficient

patients could be expected to agree to attend a medication related consultation.

Written appointment information may aid patient attendance and prevent the small

number of patients failing to attend due to forgetfulness. Where acceptable to

participants, email appointments and reminders for consultations may be effective.

This pilot study confirms that the data required for evaluation of health economics is

possible in an RCT. To address the rate of availability of cost and effect data, in any

future study we would make every effort to ensure that baseline measures are

completed prior to randomisation. The design of a definitive trial should ensure that

medical practitioners receive feedback from the students potentially to increase the

effectiveness of the intervention. Results support a future RCT as the intervention

appeared to have the potential to improve blood sugar control, quality of life, and

medicine information, and these findings need more formal testing.

Abstract

Objective To pilot and feasibility-test supervised final year undergraduate pharmacy

student-led medication reviews for patients with diabetes to enable definitive trial

design.

Method Third year pharmacy students were recruited from one UK School of

Pharmacy and trained to review patient’s medical records and provide face-to-face

consultations under supervision whilst situated within the patient’s medical practice.

Patients with type 2 diabetes were recruited by postal invitation letter from their

medical practice and randomised via automated system to intervention or usual care.

Diabetes-related clinical data, quality of life, patient reported beliefs, adherence and

satisfaction with medicines information were collected with validated tools at baseline

and six months post-intervention. The process for collecting resource utilisation data

was tested. Stakeholder meetings were held before and after intervention to develop

study design and learn from its implementation. Recruitment and attrition rates were

determined plus the quality of the outcome data. Power calculations for a definitive

trial were performed on the different outcome measures to identify the most

appropriate primary outcome measure.

Results 792 patients were identified as eligible from five medical practices. 133

(16.8%) were recruited and randomised to control (n=66) or usual care (n=67). 32

students provided the complete intervention to 58 patients. Initial data analysis

showed potential for impact in the right direction for some outcomes measured

including HbA1c, quality of life and patient satisfaction with information about

medicines (SIMS). The intervention was found to be feasible and acceptable to

patients. The pilot and feasibility study enabled the design of a future full RCT.

Conclusion Student and patient recruitment are possible. The intervention was well

received and demonstrated some potential benefits. Whilst the intervention was

relatively inexpensive and provided an experiential learning opportunity for pharmacy

students, its cost-effectiveness remains to be determined.

Strengths and limitations of this study

• The study followed recommendations published by the Medical Research

Council for implementation of feasibility and pilot studies.

• The intervention was developed with significant stakeholder involvement, a

range of primary outcome measures were tested for suitability and the

process for collecting resource utilisation data was identified.

• Self-selection bias was found within those students who consented to

participate

• The trial was unblinded with the service providers, patients and research all

aware of group allocation and intervention content

• The large number of statistical tests carried out creates the possibility that

findings could be false positives and as this was a pilot and feasibility study

which, therefore, used a low power we could potentially fail to detect small to

moderate sized effects.

Introduction

It is estimated that preventable harm from medicines costs the NHS in England £750

million per year[1]. A systematic review in 2009, based on UK research, estimated

that only between 4% and 21% of patients achieved the optimum benefit from their

medication[2]. A systematic review of publications between 1966 and 1999 reported

the prevalence of preventable drug-related admissions to hospital as 4.3%[3].

Additionally, patients not taking their medicines as agreed with the prescriber has

been reported to cost the UK NHS an estimated half a billion pounds a year[4].

Consequently, interventions designed to reduce adverse drug events and improve

patient medicines-taking behaviours are required.

Medication review (MR) has been defined as 'a structured, critical examination of a

patient's medicines with the objective of reaching an agreement with the patient

about treatment, optimising the impact of medicines, minimising the number of

medication-related problems in addition to reducing waste'[5]. MR in the UK was

described as operating at four different levels[5], with the key component of Level 3

medication reviews being the involvement of the patient whilst accessing medical

records.

Pharmacist-led medication reviews have been shown to reduce costs associated

with unnecessary prescribing of medication whilst potentially providing patient

benefit[6]. However, recent UK based research utilising pharmacists to provide

medication reviews found a counter-intuitive increase in hospitalisation[7], with one

partial explanation being the didactic nature of the pharmacist communication[8 9].

Effective communication skills are necessary to improve patient behaviours both in

terms of lifestyle[10] and medication taking[11]. Consequently, models of

consultation behaviour have been developed and are commonly used within the

education of healthcare professionals [12 13].

Whilst UK pharmacy graduates develop expertise in the pharmacology and

therapeutics of medicines, undergraduate training currently lacks significant patient

contact. This provides limited opportunities for the development of clinical and

communication skills during training[14]. In contrast, medical students routinely work

with patients during their undergraduate training[15] and undergraduate students

within Schools of Dentistry and Optometry provide services to patients under the

supervision of clinical tutors to improve both their clinical and communication

skills[16 17].

Involvement of pharmacy students in the provision of healthcare services in other

countries has been reported[18 19] with very good prescriber acceptance of student

recommendations[20]. However, pharmacy student provision of medication review

to patients in the UK, with the dual aims of demonstrating patient benefit and

improving student communication and clinical skills, has not been tested. For new

models of care to be adopted, it is necessary to demonstrate that they are likely to

be cost-effective. There is currently no evidence of this for the provision of

pharmacy student-led medication review services.

Two and a half million of the UK population currently have type 2 diabetes with an

estimated direct cost to the health system of £8.8 billion/annum[21]. Pharmacist-led

medication reviews for patients with diabetes have demonstrated significant

reductions in blood pressure[22 23] and HbA1c[24 25], both of which are necessary

to reduce long term morbidity[26]. Approximately 60% of patients are achieving the

target HbA1c below 7.5% (59mmol/mol) [27]. Due to the availability of clearly

defined national treatment guidelines[28-30] and increasing numbers of patients with

type 2 diabetes, medication review for patients with diabetes is a health service

which pharmacy students may be able to usefully provide.

A pilot and feasibility study was, therefore, undertaken in line with national guidance

for the evaluation of complex interventions[31] to determine recruitment and attrition

rates for students and patients; describe the suitability of using student volunteers;

test data collection for a future cost-effectiveness analysis; describe the potential

effects of the intervention; identify the most suitable primary outcome measure; and

estimate variance around this to enable a future trial to be effectively powered.

Method

Ethical approval was obtained from the UK health system (Cambridge 3 ethics

committee – Jan 2010) and NHS management permission was obtained from NHS

South Norfolk CCG (formerly NHS Norfolk and Waveney PCT) prior to

commencement of the study. Ethics ref no. 10/H0306/77.

University of East Anglia ethical approval was obtained to permit collection of student

examination results.

ISRCTN No 26445805 was obtained retrospectively rather than prospectively due to

misinterpretation of an NIHR email stating that “NIHR Clinical Research Network

(CRN) Coordinating centre had developed a process which enables automatic

registration of all new NIHR Clinical Research Network Portfolio studies via the

Portfolio.” We did not notice that they provided details of ISRCTN registration via

UKCRN Portfolio, later in the same email.

Student recruitment and preparation

All 84 third year pharmacy students from one UK school of pharmacy were invited to

participate in June 2011. The intervention was timetabled to occur during the final

year (fourth) of their undergraduate studies. Informed consent was obtained from

students agreeing to participate. A reserve list was created and used to resolve any

anticipated drop-out caused by the additional workload created by the study within

the students’ final year.

Standard education process already included basic training in consultation skills,

data governance and observation of a primary care doctor in practice. In addition,

participating ‘study students’ undertook four half-day training sessions comprising

the following:

• use of medical practice information systems using ‘dummy’ patient records,

• revision of ‘pharmaceutical care planning’ using a care plan designed to enable

recording of patient details and also to provide a guide to their consultations,

• a consultation skills workshop which included utilising dummy primary care

patient records and training in basic behaviour change counselling,

• two medicines-related consultations with pre-prepared and scripted professional

role-play actor ‘patients’, following which individual and group feedback was

provided.

All student activities connected with this trial were undertaken outside the university

curriculum, with students donating their time. Student preparative training was

undertaken at the University of East Anglia, apart from training in the use of

computerised medical records which was provided by NHS Norfolk and Waveney.

Examination results for students (both participating and non-participating) were

obtained at the end of year three (i.e. shortly after recruitment) to identify potential

student self-selection bias.

Medical practice and patient recruitment

Five Norfolk-based medical practices were purposively recruited by NHS Norfolk and

Waveney. The inclusion criteria were:

• pharmacist working as a prescribing advisor within the practice,

• using the SystmOne IT medical record system,

• over 200 patients registered with type 2 diabetes.

Presence of a pharmacist was required to enable student supervision; the same

system facilitate student training. A target number of patients was required to

increase the opportunity for meeting recruitment targets.

Patient recruitment

Patients in each medical practice who met the following criteria were posted a letter

from the practice asking them to participate in the study:

Inclusion criteria

• prescribed non-insulin medication for type 2 diabetes mellitus for at least two

years to increase likelihood that therapy is stabilised.

• deemed unsuitable for inclusion in the trial by their medical practitioner for any

reason,

• enrolled into other clinical trials,

• diagnosed with a terminal illness.

All recruited patients were randomised to intervention or control (standard care)

using an automated randomisation system, developed and controlled by the clinical

trials unit, which ensured concealed allocation. Randomisation was undertaken in

blocks of four to maximise equality of group size. All researchers and clinical staff

involved with generating outcome date were blind to participant allocation.

As a pilot study it was decided to test a number of potential primary outcome

measures, with results enabling a decision as to which measure to use in a future

study:

• HbA1c,

• blood pressure,

• lipid profile.

Secondary outcome measures were the effect on:

• health related quality of life (EQ-5D),

• satisfaction with information about medicines (SIMS)[32],

• medication adherence (MARS)[33],

• patient’s beliefs about medicines (The Beliefs and Medicines

Questionnaire)[34],

• diabetes treatment satisfaction questionnaire (DTSQ)[35].

Level 2 medication reviews were undertaken by students between November 2011

and February 2012 whilst student-led patient consultations (Level 3 medication

review) took place between December 2011 and March 2012.

Sample size justification

As a pilot study it was not appropriate to power the study. Consequently we

determined the likely precision of the study for estimating the effect of the

intervention on the continuous endpoints by estimating the expected value of the

half-width of the 95% confidence interval around the difference in means between

the intervention and control groups. Assuming 80 patients in each group and a

standard deviation of 1.5% in the primary outcome variable of HbA1c then the

estimate from this pilot study of the effect of the intervention on this endpoint would

be within 0.5% of its ‘true’ value. An observed difference in group means >0.5%

(e.g. HbA1c 7.0% compared to 7.5%) would be statistically significant.

From each of the five practices, 32 patients were, therefore, required providing 160

in total (80 in each of intervention and control arms). It was planned that each

student would be allocated two patients in the intervention arm for review and

consequently forty students were required.

Baseline data

Both intervention and control participants were posted a questionnaire comprising

the secondary outcome measures, which included an additional question asking

whether they used a medicines compliance aid.

The patient notes within the medical practice were investigated to obtain:

• demographic data,

• most recent results prior to recruitment for HbA1C, blood pressure and lipid

profile,

• medication utilisation (cost of all prescriptions issued for each patient for a

baseline period of three months prior to intervention and six months post-

intervention,

• NHS resource utilisation calculated as cost (using standard NHS staff cost) of

all NHS contact for a baseline period of three months prior to intervention and

six months post-intervention in both primary and secondary care.

The last two items were included to determine the feasibility of collecting data for a

future cost-effectiveness analysis within a randomised controlled trial.

Intervention

At the patient’s medical practice, students were randomised to work in pairs. This

provided additional support and shared learning in addition to the wider clinical

experience provided by access to additional patient records. Each pair, therefore,

worked to undertake Level 2 medication reviews for four intervention patients under

the supervision of a PCT pharmacist. Students compared prescribing with national

guidance[28-30] and created individualised pharmaceutical care plans (PCP) on a

predefined pro-forma.

PCPs included demographics, allergies, special needs, lifestyle e.g. diet and

smoking status, relevant medical history, medication adherence, pharmacy use,

current prescribed medication, over the counter, herbal and homeopathic preparation

use and any care issues identified. After discussion and agreement with the

supervising pharmacist, care issues identified were fed back on a custom-designed

form, to either the patient’s specialist diabetes nurse or medical practitioner who then

decided on the final action.

Patients were then offered a range of flexible dates and times, to maximise

participation of a meeting between each student and an individual patient.

The presence of a supervising pharmacist was ensured during all student-led

medication reviews to ensure competence. The consultation (Level 3 medication

review) took place at the patient’s medical practice and was separated by at least

two weeks from the Level 2 review to enable the doctor or nurse to rectify or

question any problems identified by students, prior to the subsequent student-led

consultation. As planned in the protocol, each student provided two patient

consultations which had no time limit imposed on their duration.

Follow-up

Six months post-intervention, a questionnaire was posted to both intervention and

control participants. The questionnaire was identical to the baseline version but with

an additional question regarding frequency of community pharmacy service

utilisation. Intervention participants were also asked to report any change in

utilisation of community pharmacists following the student consultation to identify any

change in attitude to or view of community pharmacists. The same data as baseline

were collected from the medical practice, with HbA1c, blood pressure and lipid

profile collected at six months post-intervention with a cut-off point of one year; and

medication and resource utilisation for the six month period post intervention.

Stakeholder meetings

Stakeholder meetings were held with patients, students, primary care pharmacists

and medical practice staff both before and after the intervention. Interested

individuals were recruited prior to the study’s implementation to inform the design of

the intervention and trial, whilst study participants were recruited post-intervention to

learn from their experiences. All meetings were recorded and transcribed verbatim.

Data analysis

The variance in the difference between each primary or co-primary outcome

measure between groups was undertaken on an intention-to-treat basis using

independent t-test and Mann-Whitney U test. The patient recruitment rate and the

medicine-related consultation uptake rate were both determined. SPSS version 22

was used for analysis.

Stakeholder meeting analysis

Simple content analysis which proceeded to identify all themes, as recognised by the

researcher, was undertaken for development meetings with the main learning points

recorded for action as appropriate. Review meeting analysis followed the general

principles of the framework approach[36]. There was no independent analysis of the

data. Nvivo 10 was used to facilitate analysis.

Health economics analysis

As a pilot study we report completion rates for resource use items and the EQ-5D.

Additionally, unit costs[37] were extracted in order to enable the cost of the

intervention to be estimated.

Results

All five medical practices which responded to recruitment requests were consented

to join the study.

Figure 1 summarises the patient recruitment process which achieved a 16.8%

consent rate. Recruitment rates within the five medical practices were 17.2%,

19.6%, 20.1%, 18.5% and 9.4%. The research team received a number of contacts

from patients who had been approached by the medical practice with a 9.4%

response rate to complain that they had received recruitment letters without stamps.

The first two practices recruited in time to enable students to complete medication

reviews before Christmas 2011. The other three practices recruited later resulting in

student-led medication reviews in one practice being undertaken in March 2012. Of

the 67 patients randomised to intervention, 91.0% remained in the study prior to the

student-led medication review with 100% of those agreeing to an appointment with a

student for a consultation. Of these, three (4.9%) failed to attend the consultation.

Figure 2 provides a summary of the flow of students at each stage of the study. Of

the 47 students who volunteered and completed a consent form, 12.75% were male.

The first 40 students volunteering were recruited with the remaining seven forming

the reserve list used if recruited students left the study. Patient consultations were

undertaken by 32 of the 47 (68%); however, of these six only undertook one

consultation due to patient numbers. Mean (SD) exam scores at end of year three

(at recruitment) for participating and non-participating students were 62.80 (7.91)

and 58.91 (7.98), respectively. Academic performance of participating students was

significantly better than non-participating students at the point of recruitment (p<0.05,

independent samples t-test).

Table 1 presents baseline, demographic, clinical and questionnaire data for control

and intervention patients. The data indicate that randomisation resulted in

reasonably comparable groups, although the wide standard deviation demonstrates

considerable numbers of patients in each group were failing to achieve clinical

targets.

Table 2 presents six months post-intervention data including clinical data and results

of patient-completed questionnaires. Questionnaire responses were received from

94 (70.7%) of the 133 patients with non-respondents and omission of responses to

individual questions being comparable across the two groups. Significant

differences between intervention and control groups were only observed for change

in quality of life and some elements of SIMS.

Figure 3 illustrates a comparison of the SIMS questionnaire responses for

intervention and control patients at follow up (six months post-intervention). It

demonstrates that patients in the intervention group were significantly more satisfied

with five parameters (one action and usage, four concerns) out of the 17 questions.

to speak to a pharmacist about their medicines or their health following the

medication review, whilst 11 (24.5%) were unsure.

It was calculated that for a full RCT to demonstrate an effect on HbA1c, 159 patients

would be required in each arm of control and intervention to demonstrate 80% power

with 214 patients per group to demonstrate a 90% power. Data utilised for sample

size analysis are presented in Table 3.

Health economics analysis

The mean per participant cost of the intervention was £164.41; Table 4 provides a

breakdown of the component parts. We used different versions of the EQ-5D (the

five level version[38] at baseline and the three level[39] at follow-up) to assess

whether completion rates differed according to the number of levels. The response

rates were slightly higher for the EQ-5D-3L and the mean change in EQ-5D score

was slightly higher for the intervention arm (see Tables 1 and 2). Complete cost and

effect data were available for 72 participants (54.1% of the sample).

Stakeholder meetings

All stakeholder groups supported the testing of the idea. There was agreement that

student-led consultations should take place at the medical practice of each patient

rather than at the university, should not be time-limited and should be supervised.

Post-intervention stakeholder groups agreed that the experience had been generally

positive, had provided both student and patient benefit and raised awareness of the

role of pharmacists.

Discussion

This pilot study has demonstrated the acceptability and practicality of pharmacy

students providing full medication review to patients with type 2 diabetes under

supervision. All stakeholder groups displayed support for the concept, with patients

also displaying a willingness to participate in a subsequent RCT. Medical practices

were purposively selected, and no problems were experienced with patient

recruitment, though recruitment rates were relatively low (17%) and may display a

better response rate without postal issues experienced at one medical practice.

Nevertheless, future recruitment for a full RCT would be possible and may display a

better response without postal issues experienced at one medical practice.

Importantly, there was also a very low patient dropout rate (<10%). The logistics of

patients having to attend an additional clinic within the intervention group resulted in

the loss of patients due to illness and bereavement which were unavoidable losses

to the study and two due to forgetting to attend. A longer period to allow for

rebooking and reminders closer to the time of the appointment may have prevented

these drop-outs. A longer time period to allow for rebooking and reminders closer to

the appointment may have helped but would increase the costs. Potential patient

benefit was also identified within some of the outcome measures. The results,

therefore, provide evidence that within an RCT, sufficient patients could be expected

to agree to attend for a medication related consultation.

As this was a pilot study, and had small participant numbers we did not expect to

demonstrate significant effects in our outcome measures. Students were volunteers

and may not represent a full population of undergraduate pharmacy students. All

participating medical practices were requested to commence recruitment at the

same time; however, results demonstrate patient recruitment proceeding over a

period of greater than four months, resulting in logistical issues within the project.

Ethical reasons required recruitment to be initiated via the medical practices, but

results suggest that closer communication and support may be required between the

researcher and medical practices to facilitate earlier recruitment. Written

appointment information may aid patient attendance and prevent the small number

of patients failing to attend due to forgetfulness. The large number of statistical tests

carried out, increases the likelihood of false positives. Conversely as a pilot and

feasibility study with limited sample size there is an increased likelihood of false

negatives.

Whilst student willingness to participate was high, pressures of concurrent timetabled

course work and a lack of confidence in ability to perform the consultation resulted in

significant drop out during the progress of the study. Integration of the service into

the curriculum did not result in drop out from similar non-UK studies[18 19].

Participating students were volunteers and, therefore, self-selecting. Given that they

were, on average, academically superior when compared to non-participating

students, they would potentially have performed better than non-participants during a

student-led consultation. Most studies do not mention this effect and any future

study utilising volunteer students should recognise and allow for it[18 40-43]. The

educational element of this study was not considered within this paper as this will

form the focus of a future submission. The quality of medicines information given to

patients affects individual’s perception of whether it has met their needs and if they

are satisfied with the information provided[32]. It is reasonable to speculate that

repetition of information over a period of years to patients with a long-term condition

would have resulted in a greater understanding of and, therefore, satisfaction with

information about their medicines. This may have reduced the ability to improve

scores for many of the individual questions. Whilst higher scores for SIMS is

theoretically a predictor for better adherence (MARS)[32] no improvement in

adherence was observed. The relatively high proportion of patients who reported

using medication compliance aids prior to the intervention might have reduced the

potential for the intervention to further improve adherence. Adherence, beliefs about

medication, satisfaction with diabetes treatment and quality of life all displayed a

change in the direction which favours the intervention, all of which support a full

study going ahead. No evidence is available to definitively explain the change in

blood pressure seen in the control group and reasons for this would only be

speculative, but it may simply have been a chance finding. It may be more

appropriate to focus the intervention on those patients with the greatest HbA1c or the

lowest reported satisfaction with information or adherence, however this may affect

the recruitment rate and would require careful consideration prior to implementation

in a full RCT if using the results from this study for it basis.

Results demonstrate that HbA1c would appear to be a sensible primary outcome

measure for a future study. A sample size of 214 patients per group (428 in total)

would be required to demonstrate a 90% power. This would equate to 107 students

(two patient consultations per student), which is achievable within a full RCT

undertaken over more than one school of pharmacy. However, recent NICE

guidance recommends the utilisation of a cardiac risk measure (QRisk2)[44-46]

which represents a compilation of clinical data. Insufficient data is available to

calculate a sample size for QRisk2, therefore, the pragmatic decision would be to

utilise a primary outcome measure of HbA1c with QRisk2 possibly utilised as a

secondary outcome measure.

Implementation of student activity described within this study is in line with current

government agenda for pharmacy education[47]. Evidence does not exist in the UK

to support the training of undergraduate pharmacy students when undertaking

activities with real patients, although examples exist outside the UK[18 19 42]. This

study does not provide definitive evidence for this, but does provide support for a

future definitive RCT to test this hypothesis.

With a known patient recruitment rate and low dropout rate this demonstrates that if

utilising the same protocol for a future RCT, not only can sufficient numbers of

patients be expected to be recruited and retained. Medical practices were chosen

because they all used the same software system for electronic medical records, as

this would facilitate student training, however, utilising additional systems would

increase the number of GP practices available for recruitment. Changes may be

warranted to patient selection criteria, as recruitment of patients who are not yet

clinically stabilised may be more receptive to information regarding their medicines.

NICE CG66[44] recommends a blood pressure target level of <140/80mmHg for

most people with type 2 diabetes, and <130/80mmHg for those at more particular

risk. The latter group includes people with raised albumin excretion rate (AER)

(microalbuminuria or worse), eGFR <60ml/min/1.73m2, those with retinopathy, and

those with prior stroke or transient ischaemic attack (TIA). Data to enable such

differentiation was not obtained within the pilot study and should be included in the

design of a future definitive RCT. Provision of opportunities for students to

undertake more than two consultations in future studies may demonstrate further

student and patient benefit. Results provide evidence that within an RCT, sufficient

patients could be expected to agree to attend for a medication related consultation.

Written appointment information may aid patient attendance and prevent the small

number of patients failing to attend due to forgetfulness. Where acceptable to

participants, email appointments and reminders for consultations may be effective.

This pilot study confirms that the data required for evaluation of health economics is

possible in a RCT. To address the rate of availability of cost and effect data, in any

future study we would make every effort to ensure that baseline measures are

completed prior to randomisation. The design of a definitive trial should ensure that

medical practitioners receive feedback from the students to potentially increase the

effectiveness of the intervention. The results from this study display good

generalisation, as recruitment and the intervention followed existing scenarios where

possible, however student academic ability may affect interpretation. Results

support a future RCT as the intervention appeared to have the potential to improve

blood glucose sugar control, quality of life and medicine information, and these

findings need more formal testing.
