INTRODUCTION

Handover or hand-off is the accurate, reliable com-munication of task-relevant information across shiftchanges1 and is vital to facilitate high-quality healthcare.2 Its importance has increased in recent yearsin the UK as the introduction of the EuropeanWorking Time Directive has resulted in a greaterfrequency of handover as a consequence ofreductions in working hours.3 In the USA, whereworking hours are being similarly reduced,communication failure at handover has been identi-fied as a major source of error within patient care.4

Previous literature has identified failings in currenthandover strategies5–8 and the potential for these toharm patients.9 Numerous published works discussways to improve handover and many of them focus onsystems to manage information, such as standardisedproformas10,11 or electronic handover systems.12,13

There has also been some discussion of the use ofmnemonic devices to guide handover, although thereis a paucity of evidence as to their effectiveness.14

Despite these innovations, research has identifieddissatisfaction amongst junior staff15 with currentpractices as a result of the lack of policies andtraining.16 There have been calls for formal handovereducation17 and work has started to clarify compe-tencies for training.18 In addition, handover isincreasingly recognised within graduate curricula inboth the UK19 and the USA.20

In 2008, Arora et al. presented a theoretical frame-work using theories grounded in social sciences toexplain how handover can impact on patient care.18

They discussed the possible erosion of professionalismoccurring in settings of discontinuity. This can lead tostaff failing to take responsibility for the care ofpatients in a manner that alludes to what is aptlynamed ‘shift-work mentality’, a concept which issupported by agency theory. Under this theory, thepatient does not have access to the information he orshe needs to make an accurate judgement on whethera doctor is behaving in his or her best interest. The‘agency problem’ refers to the potential for doctorsto shirk their professional responsibility in such asetting. This theory would suggest the importanceof professional attitudes to safe handover. Alsodiscussed is the management of information athandover as a source of error and how this relates toan economic theory, known as ‘coordination costs’.This describes how, in increasingly complex systems,the costs (either financial or time-related) ofcoordination, including information management

and communication, increase. Systems are thereforeneeded to safely manage these potential increases.

A complete model of handover practice has previ-ously been reported.21 It describes three overlappingareas of handover practice: (i) information transferand systems for managing information; (ii) responsi-bility and accountability, and (iii) system elements inplace to facilitate handover, such as teamwork andleadership. Recently, theories from the psychologicalsciences have been applied to handover communi-cation.22 This research found that doctors often didnot communicate vital information; they knew whatthey were trying to convey and therefore felt it wasclear to everyone. This overestimation of how wellthey communicated made doctors less likely to verifywhether the receiving doctor had understood. Thisconcept of an egocentric heuristic, associated withhandover communication, led the authors to stressthe importance of focusing on communication withinthe team.22

It is recognised that most junior doctors receive littleor no education in handover6 and this contributesto weaknesses within handover systems.23 The extentto which educational interventions are used toimprove handover and how well the conceptualframeworks and models described here are reflectedin these interventions remain unclear. Evidence forthe effectiveness of these interventions is also unclear.We set out to determine the characteristics ofeducational interventions employed to enhancehandover amongst health professionals and toestablish the effectiveness of these interventions.

METHODS

Data collection

All interventional study designs were considered forthis review. Commentary pieces, surveys, audits orreview articles were not included. The targetpopulation consisted of medical and nursing staff,including undergraduates. The setting was in-patientmedical establishments. Studies involving alliedhealth professionals, who do not hand over within theacute in-patient setting, were excluded. Outcomes atany level of Kirkpatrick’s adapted hierarchy24 wereconsidered for inclusion. Kirkpatrick’s modeldescribes four levels of outcome that can be assessedwhen studying an educational intervention. It istherefore useful to communicate the type of evidencegenerated when investigating an intervention. Level 1

describes outcomes associated with the reaction to anintervention, such as satisfaction. Level 2a describesattitudes and confidence, and Level 2b describesknowledge and skills. Level 3 describes outcomesassociated with changed behaviour, such as thetransferring of skills to the workplace. Level 4describes patient outcomes; thus, in the context ofhandover, this may include patient safety data.

An educational intervention was defined as anystructured educational activity. Interventions thatintroduced new handover systems or mnemonicswithout an educational component were excluded.All interventions as defined above were reported. If astudy reported an intervention in limited detail orcommented on improved handover without present-ing evidence in support of the improvement, weattempted to contact the author for further details.Studies from all countries published in all languageswere included. There was no time limit on the search,which was run in June 2010.

The following online databases were searched using astandardised search strategy (Appendix S1, online):MEDLINE; EMBASE; CINAHL (Cumulative Index toNursing and Allied Health Literature); British Nurs-ing Index (BNI); PsycINFO; ERIC (EducationalResource Information Centre); British EducationIndex (BEI), and the Cochrane Trials Database.Additionally, reference lists from included studieswere searched for further relevant studies. Abstractsavailable online from relevant education societies,including the Association for the Study of MedicalEducation (ASME) and the Association for MedicalEducation in Europe (AMEE), were also searched.

Data analysis

Citations were reviewed independently by each of theauthors. Agreement between reviewers was assessedusing Cohen’s kappa statistic. Potentially relevantabstracts were independently reviewed using ascreening checklist (Appendix S2) and full papersobtained for any studies that appeared to meet theinclusion criteria. Disputes were resolved by consen-sus. The full manuscripts for all included studies wereassessed independently by each of the authors. Thequality of the studies was assessed using a dataextraction form (Appendix S3), based on guidanceavailable from Best Evidence Medical Education(BEME),25 as well as the recommendations of Reedet al.26 This rated studies according to each of 16quality-based criteria. The strength of the conclusionsdrawn by each study was rated on a numeric scale,also in line with BEME guidance.25 This is not an

assessment of overall methodological quality, but ameasure of how well the conclusions made aresupported by the data presented. The importance ofoutcomes was also assessed by relating them toKirkpatrick’s adapted hierarchy.24 Disputes in thesejudgements were resolved by discussion between theauthors until they achieved consensus. Contentanalysis of available or supplied interventions, codingand categorisation into themes were carried outindependently by each of the authors.

RESULTS

The initial search of electronic databases identified780 citations, of which 298 were unique. All abstractswere read by both reviewers. Agreement betweenreviewers on citation screening was almost perfect(j = 0.97) and the authors agreed that 40 citationswere potentially relevant. Their abstracts werereviewed using the screening checklist (Appendix S2).There were no potentially relevant abstracts fromscientific meetings of ASME or AMEE. The initialscreening identified a total of 19 studies for fullscreening.

These 19 studies were independently reviewed byeach author and nine papers27–35 were excluded asnot relevant, with no disagreement between theauthors. This left 10 studies36–45 which met theinclusion criteria. No further potentially relevantstudies were found from searching the referenceswithin the included studies. A flow diagram of thesearch is shown in Fig. 1. An overview of the includedpapers is shown in Table 1. Data were extractedindependently by each of the authors, who achievedconcordance on 88% of quality ratings and subse-quently met to reach consensus. Consensus results ofthe quality assessment in each of 16 criteria are shownin Table S1.

There was significant methodological heterogeneityamong the studies, as well as among the educationalinterventions used. Study participants includedmedical students, doctors, nurses and nurse special-ists. The mean number of participants in a studywas 38 (range: 14–72). The studies included sixbefore-and-after studies, three action-based studiesand one non-randomised controlled study. Themajority of studies did not offer details of theintervention used or the resources the interventionrequired. All studies, apart from one,40 had outcomesat Level 2 of Kirkpatrick’s adapted hierarchy,24

measuring either the modification of attitudesor perceptions (Level 2a) or, alternatively, the

modification of knowledge or skills (Level 2b). Theremaining study, by Gakhar and Spencer,40 measuredthe transfer of handover skills into the workplace(Level 3). The strength of conclusions as estimatedusing the BEME scale25 was deemed to be poor in threeof the studies,42–44 which achieved BEME scores of 2.0,representing ambiguous results that may suggest atrend. Three studies36,38,45 achieved BEME scores of3 out of 5, indicating that their conclusions were mostlikely based on results. The strength of conclusionswas judged to be good in four of the studies,37,39–41

which won scores of 4.0, suggesting their conclusionswere clear and very likely to be accurate.

The authors of all but two studies39,40 were contactedand asked to give more information about the inter-ventions used. Five of the authors responded37,38,42–44

by providing narratives of their teaching methods orcopies of materials used that had not been included inthe published manuscripts. These were used in theanalysis of teaching methods and content themes. Thekey outcomes of the analysis are shown in Fig. 2. Themain teaching methods employed were simulation orrole-play, either exclusively, or as part of an overallpackage of measures. Common features were the useof observation, evaluation and feedback. Group lec-tures and online materials were also used in several ofthe interventions.

In line with the literature on the topic, the theme ofinformation management became apparent withinthe content of the educational interventions and was

made clear by the discussion of mnemonics, check-lists or technology. The second theme to emergeconcerned the recognition of error caused by inad-equate handover. This was usually discussed in thecontext of fostering a joint professional responsibilityto prevent such errors, thereby enhancing patientsafety. The third theme concerned team-working andcommunication. A number of ideas were discussedwithin the interventions, such as how to communicateacross a power gradient. Many interventionsinvolved senior members of staff in the training, bothin order to provide models of good practice andto allow these staff to receive handover training.

DISCUSSION

This review found a general paucity of researchsupporting and directing the use of educationalinterventions to improve handover. This is inagreement with the findings of previous research.46

Interestingly, of the 10 studies included, eight hadbeen published in the previous 2 years. This highlightsthe fact that recognition of the need for goodhandover is gaining momentum amongst cliniciansand educationalists, probably in response to worldwidemoves towards decreasing doctors’ working hours. Itis hoped that this systematic review will serve tostimulate further research into the effectivenessof educational interventions to improve handover.

The studies in this review were generally judged to be ofpoor methodological quality (Table S1). Most studiesgave limited information on the specifics of theintervention. Although a number of authors providedfurther details on request, the lack of publishedmaterials limits the scope for other researchers to buildon the educational interventions presented andreaders would struggle to replicate many of them. Anumber of the studies were also considered to haveproposed conclusions that were not supported by thedata they presented. Several factors contributed tothis, including the aforementioned methodologicalweaknesses, the use of multiple system changes thatconfused the impact of the educational component,and the lack of any clear conclusions.

Most studies reported outcomes at Level 2 ofKirkpatrick’s hierarchy; just one study reported out-comes at Level 3, signifying the transfer of skills to theworkplace.40 No study demonstrated that handovereducation could improve patient outcomes (Level 4).Research investigating other methods to improvehandover has also failed to show this.47 As theultimate goal in improving handover is to enhance

patient safety, this deficiency in evidence must berecognised and future work designed to rectify thesituation.

There are currently no internationally recognisedcompetencies and outcomes for handover education,

which may have contributed to the heterogeneityamongst the educational interventions used in thestudies reviewed here. Despite this, there were anumber of recurring teaching methods. Simulationor role-play were employed by a number of thestudies36,39–42,45 and previous research17 has foundthat doctors feel these are useful in developinghandover skills. These studies employed debriefingand feedback, which have been shown to improveperformance after simulation teaching.48

A number of key content themes were identified; thesecan be related to the previously described theoriesconcerning handover. The first content theme ofinformation management clearly relates to the theoryof ‘coordination costs’18 and refers to the systemsneeded to manage increasingly complex handovers.The second content theme of error relates to thepreviously described agency theory.18 The interven-tions discussed error in the context of fosteringjoint professional responsibility. This challenges the‘shift work’ mentality and therefore may improvepatient safety. The final theme of communicationand team-working relates to the theory of egocentricheuristics,22 which was discussed within a lectureused in one of the interventions.39 These contentareas clearly align with the previously discussedmodel of handover.21 This would seem to be anappropriate model, with a theoretical basis, fordesigning education to enhance handover skills,

supported by the limited evidence available in theliterature.

The use of these teaching methods and contentthemes is paralleled by work in other fields. TheNational Aeronautics and Space Administration(NASA) determined that many crashes were causedby failures in interpersonal communication, decisionmaking and leadership.49 A teamwork and simula-tion-based intervention to improve safety, designated‘crew resource management’ (CRM) training, wasdeveloped. It focuses on behaviour in teams andencourages the individual to speak up if something isnot being done appropriately. This is intended tocombat the sort of bystander apathy that can occur ingroups, as described in social science theories con-cerning diffusion of responsibility.50 It also embracesthe importance of learning from error to preventrecurrence.51 Training in CRM has already beenadapted in health care, most notably by anaesthe-tists.52 Catchpole et al.53 recently interviewed FormulaOne (F1) racing teams and found similar attitudes tohandover reflecting the same three broad contentthemes. This triangulation with other fields supportsthe utility of the handover model21 for guiding futureeducational design in health care.

This systematic review has several limitations.Although this selection was not limited by languageor date, it included only papers reporting inter-ventions with doctors or nurses in the in-patientsetting. A decision was made to limit the inclusioncriteria in this way as handover itself is not a singlewell-defined task, but is a rather heterogeneousactivity that takes place in many aspects of healthcare and therefore can take many different forms.The screening process excluded a small number ofstudies which reported educational interventionsaimed at improving handover in health care in otherallied groups, such as when patients were movingfrom one primary care establishment to another orarriving by ambulance for care. These describeddifferent models of handover and thus differenttopics for education. A further review looking athandover in all areas of health care may wish toinclude these. This review has followed its remit ofassessing educational interventions to improvehandover, but there are many other forms ofintervention that are also intended to do so. Readersmay wish to research these alternative methods.Most studies gave only limited details of the inter-ventions used and, although some authors offeredextra data, the analysis of content themes andteaching methods is limited by this lack of detail. Itmust also be noted that this review has only included

research of an interventional nature. Although wehave touched upon a number of other streams ofwork in this discussion, we did not undertake athorough review of the wider literature on the topicand this should be considered in any assessmentof our conclusions. All of the studies included inthe review reported positive results of their educa-tional interventions and therefore the possibility ofpublication bias must be considered. Certainly,this lack of negative results inhibits any comments asto the relative impact of different learner character-istics on the success of such interventions. Finally,none of the studies attempted to assess the long-termretention of the outcomes measured and thisfurther limits the conviction with which we canconclude that such interventions are effective.

We would suggest that further work is needed toclarify the competencies required by health care staffto make effective handovers. Such work should take amultidisciplinary view of health care handover andcover the issues of communication across disciplinesand the power gradient. Further assessment andrefinement of the utility of the model for guidinghandover education discussed in this review shouldalso be attempted. We would also suggest that furtherwork is needed to develop interventions to improvehandover skills. The use of methods that parallelCRM and F1 race team training may be considered.Reports of such interventions should give sufficientdetails to allow replication. Whichever investigativetechnique is chosen when assessing such interven-tions should be robustly utilised and well describedon publication. Finally, consideration should be givento the possibility of assessing whether such interven-tions can impact on patient outcomes.

CONCLUSIONS

There is a paucity of research investigating educa-tional interventions to improve handover amongstmedical and nursing staff, although this field isgrowing rapidly. The studies reported suggest thateducational interventions can improve handover,but small sample sizes, the lack of research intolong-term retention and the possibility of publicationbias limit the significance of this conclusion. Themethodological quality of reported studies is generallypoor. There is limited evidence demonstrating thetransfer of skills to the workplace and no evidence thatthese interventions improve patient outcomes.Further work is needed to establish clear competen-cies for handover training. In addition, further
