An Analysis of the Staphylococcus Aureus (SA) DecolonisationPatient Group Direction (PGD) in Elective Spinal Surgery Patients Authors: Annesha Archyangelio- Infection Prevention and Control Nurse and Amritpal Shakhon-Specialist Pharmacist Antimicrobials and Infection Control
BackgroundWhat is a Patient Group Directives (PGD)?
n A is written instruction for the supply and / or administration of a named licensed medicine for a defined clinical conditionn Allows a range of specified registered health care professionals to supply and / or administer a medicine directly to a patient with an identified clinical condition without them necessarily seeing a prescribern The health care professional working within the PGD is responsible for assessing that the patient fits the criteria set out in the PGD (Statutory Instrument, 2000).
Patient GroupSpinal patients - identified as having a higher infection rate
n Capturing spinal patients seen through pre-operative assessment (POA) clinic to provide staphylococcus aureus (SA) decolonisation treatment to alln Chlorhexidine 4% body/hair wash, Mupriocin 2% nasal ointment and Chlorhexidine 0.2% mouthwash to be used by prior to and on day of admission to reduce bacterial load prior to surgeryn Implementation started in POA in June 2014n POA staff marked ICS (Electronic Computer System) records for patients to whom they provided the PGD to monitor compliance and distribution of the PGDn The categories of patients who did not receive the PGD/decolonisation include hips, knees, shoulders, foot and ankle and spinal patient who did not attend POA clinic. n Patient in this group will be screened for Methicillin-resistant Staphylococcus aureus (MRSA) in line with current practice, any MRSA positive patients will receive the standard MRSA decolonisation
(chlorhexdine body wash and Mupirocin nasal ointment only).
Methodn A post-implementation audit and review of the SA PGD from June to Dec 2014
n Identification of patients captured via Insightn Understanding reasons why some patients not given the PGD by checking ICS recordsn Ascertaining the change in infection rates since introduction of the PGDn Staff interviews to understand implementation process and difficulties encounteredn Patient surveys to understand how decolonisation treatment explained and used in practice
n Surgical patients not given the PGD who are found to be colonised with another organism otherthan MRSA do not receive the decolonisation treatment. Hence the current routine MRSA data collected in this group of patients will be used as a comparison

Results
Staff Feedback: PGD Interview Summary Results:8 staff interviews were completed, 1 staff did not distribute the PGD, no patient objected to the PGD, 1 patient identified as having peanut allergy and did not receive the PGD, no report of allergy / sensitivity to the chlorhexidine,no patient who could not physically use it and there was slight confusion with the number of days / times per day touse the PGD.
Process of informing patient about the PGD: All (7) staff;n Used the patient leaflet/pack to inform patients about the PGD n Explained it is for patients having spinal surgery to reduce infectionn Asked to use PGD on all areas of the bodyn Determine if patients need assistance as part of the usual assessment processn Said training was sufficientn Okay adding PGD flag and infection control notes on the ICS and in notes/booklet
Patients Feedback: 11/30 Questionnaires returned;
n 11 Patients indicated the PGD is to reduce infection after surgery, received information leaflet/ instructionson how to use it and used it based on the instructions given.
n 9 understand the importance of PGD, while 5 were satisfied with the advice givenn 10 were able to ask questions about the PGD, had no issues causing difficulty in applying the PGD and 10
applied PGD to all areas of the bodyn 7 followed PGD instructions fully, while 3 couldn’t reach all areas of the backn 9 said they were told PGD would last 5 days and 9 had no problems with the decolonisation
Findings / Discussionn Most patients who had not received the PGD did not have POA and so the decolonisation treatment could
not be issued to them n Some patients attended POA with no documentation of the PGD being given
this has been highlighted to pre-assessment so they can find out the reasons for this and tackle this issuewith staff
n Other reasons for non-issue of the PGD decolonisation treatment included the non-inclusion of private patients, telephone assessments and pre-operative assessments conducted prior to the PGD n Private patients will be being recorded and captured in the future
n The proportion of patients given the PGD is lower in the initial months due to their POA occurring prior tothe introduction of the PGD which created a lag in the figures.
n The uptake was much better in October and November with a small drop in December. n There is a time lag with SSI rates making it difficult to assess the true impact of PGD implementation.
n Crude numbers show a reduction in SSI rates in spinal patients compared to the same period year. n Overall the PGD protocol was complied with by staff and patients, minor issues identified were rectified
Conclusionn PGD implementation occurred smoothly in POA
n Staff feedback confirmed thisn No calls to infection control from patients querying the use of decolonisation treatment
n The number of patients captured is expected to increase in the future after inclusion of private patientsn It is recognised that patients not without a POA prior to admission or who are telephone assessed will a
ways be missed with this method of implementation
Recommendationsn Continue to analyse PGD distribution and infection rates to assess the impact of blanket decolonisation in spinal
patientsn Consider if standard decolonisation regime is warranted for all orthopaedic patients prior to surgery
n Discuss methods to capture patients who cannot attend POA

Spinal patients with Surgical Site Infection (SSI)n June – December 2013 (Pre-PGD implementation)- 19 SSIs: No decolonisation was routinely given to spinal
patients – higher infection rate for these quarters.n June – December 2014 (Post PGD implementation)- 7 SSIs:
Of the 7 patient with SSIs: 1- was pre-op assessed prior to the PGD commencing.n 3- were pre-op assessed, had the PGD and still had SSIs - all 3 patients confirmed using the decolonisation
treatment however one patient was not able to apply body wash to all of back area as they could not reachn 3- patients met the criteria were not pre-op assessed, did not receive the PDG and Had SSIs
