Background Despite being essential to patient care, current clinical handover practices are inconsistent and error prone. Efforts to improve handover have attracted attention recently, with the ISBAR tool increasingly utilised as a format for structured handover communication. However, ISBAR has not been validated in a junior medical officer setting.
Objective To assess the effect of the ISBAR handover tool on junior medical officer (JMO) handover communication in an Australian hospital.
Methods JMOs who participated in after-hours handover during an 11 week clinical term from June to August 2009 were recruited. After-hours handover was audiotaped, and JMOs completed a survey to assess current handover perception and practice. JMOs then participated in a 1 h education session on handover and use of the ISBAR handover tool, and were encouraged to handover using this method. Following the education session, participants were surveyed to measure perceived changes in handover with use of ISBAR, and handover was again audiotaped to assess differences in information transfer and duration.
Results Following the introduction of ISBAR, 25/36 (71%) of JMOs felt there was an overall improvement in handover communication. Specifically, they perceived improvement in the structure and consistency of handover, they felt more confident receiving handover, and they believed patient care and safety were improved. Audio-tape data demonstrated increased transfer of key clinical information during handover with no significant effect on handover duration.
Conclusions Use of the ISBAR tool improves JMO perception of handover communication in a time neutral fashion. Consideration should be given to the introduction of ISBAR in all JMO handover settings.

Handover is defined as the transfer of professional responsibility and accountability for the care of a patient.1 With increasing focus on safe working hours, demand for part-time work and the move towards multidisciplinary patient care, handover is occurring more frequently.1 2 A recent Australian study estimated that patients see an average of 6–10 doctors per admission.3 However, current handover practices are criticised as being highly variable, unstructured, and error-prone.4 International evidence suggests few trainees receive formal instruction on the handover process, and it is unknown how many medical students and junior doctors in Australia currently receive training or evaluation in handover.5 Inadequate handover has implications for patient care and safety, with communication failures identified as the root cause in over 70% of adverse hospital events.6
A number of recommendations have been made on how to improve handover. These include ensuring a set time and place free of interruption, training sessions, senior supervision and use of electronic aids.1 5 7 8 One important recommendation is that handover should follow a standardised approach,2 9 such as the framework designated by the acronym ‘ISBAR’ (figure 1).
The ISBAR tool may improve handover by providing a template which creates a clear picture of the patient's clinical issues while also defining outstanding issues and tasks.10 It aids communication by offering an expected pattern of transferred information so errors or omitted information become clear.9 11 12 Studies on ISBAR have shown that it can have a substantial impact on improving the quality of handover.13 It is a well received, easy to remember tool, and has been shown to reduce rates of adverse events.12 14
Despite handover practice being widely discussed in the literature, there is no substantial evidence to justify changes in practice.15 Furthermore, there are no published studies focusing on the use of ISBAR in handover between junior doctors, and no well established evidence base for best practice in handover between JMOs.16 17 The aim of this study was to assess the effect of the ISBAR handover tool on clinical handover between JMOs in a tertiary hospital setting, in terms of JMO perception of handover, transfer of key clinical information, and duration of handover.
The study was conducted at Royal North Shore Hospital (box 1) during an 11 week JMO clinical term from June to August 2009, following approval by the Northern Sydney Central Coast Human Research Ethics Committee. Forty-four JMOs (interns, residents, and medical registrars) rostered to after-hours handover during this period were asked to consent and participate in the study. Box 2 outlines overtime and handover practices at Royal North Shore Hospital. The ISBAR tool was selected for this study ahead of other handover tools as it is the most extensively studied.18 The study was divided into three phases.
Royal North Shore Hospital
Royal North Shore Hospital (RNSH) is a 600 bed tertiary referral teaching hospital located in Northern Sydney, NSW, Australia.
It has over 42 000 presentations to the emergency department each year, and over 46 000 patients admitted to hospital each year, with an average length of stay of 4.1 days.
RNSH is a trauma centre and offers treatment in major specialty areas.
RNSH is one of two spinal injury and burns referral centres in NSW.
Overtime shifts and handover at Royal North Shore Hospital
After hours, Royal North Shore Hospital (RNSH) is covered by intern and resident staff who are responsible for reviewing any unwell or deteriorating patients, updating patient charts, and also performing any specific tasks requested by the treating team. Each JMO covers 3–6 wards of approximately 25 patients each. The overtime shift lasts 6–8 h.
A medical registrar is in the hospital at all times to supervise and assist the intern and resident staff as needed. A medical emergency team (MET) consisting of intensive care and anaesthetic support is also available to assist with acute medical emergencies.
At the end of each overtime shift, a formal face-to-face handover occurs in an assigned, private location. These occur at 10 pm each evening and 8 am on weekends or public holidays (nine handover sessions per week). The handover is supervised by the medical registrar. On weekdays, there is no formal morning handover—the night staff are responsible for contacting the relevant day team directly regarding any unwell patients.
Handover typically lasts 15–30 min, with between 10 and 20 patients handed over each session. Unwell patients requiring review as well as any outstanding tasks are handed over to the incoming doctor.
The incoming doctor records details of the handover as he or she chooses, usually as short notes. No handover artefacts were in use at the time of this study.
At the completion of the handover session, each overtime doctor is responsible for reviewing the patients which were handed over to them and completing any outstanding tasks.
Approximately 40–50 interns and residents participate in overtime each clinical term (lasting 10–11 weeks), with each JMO participating in approximately one overtime shift per week.
Phase 1: Collection of Pre-ISBAR baseline audiotape data (weeks 1–3)—In the first 3 weeks of the clinical term, baseline data were collected by audiotaping after-hours JMO handover meetings. The nine handover meetings which occur each week are supervised by the after-hours medical registrar, who was responsible for audiotaping handover during the study period.
Phase 2: Baseline survey and education session (weeks 4–7)—In phase 2, participants completed a baseline survey to assess their perception of existing handover practices (table 1). The survey contained eight statements to which the respondent was asked to agree or disagree according to a six point Likert scale, and participants were also asked to comment on how handover practices could be improved. Participants then attended a 1 h education session focusing on the importance of effective handover and use of the ISBAR communication tool. The education session was held at four separate times to maximise JMO attendance, and also videotaped with a DVD provided to those JMOs who did not attend the session. Each session was conducted by the Director of Prevocational Education and Training at Royal North Shore Hospital, assisted by two study authors. Further, JMOs were provided with a card to remind them of the ISBAR acronym that readily attached to their hospital identification badge, and large posters were erected in the JMO handover room. Participants were given 3 weeks to gain familiarity and proficiency with the ISBAR tool and were encouraged to use the ISBAR tool at handover meetings.
Phase 3: Collection of post-ISBAR audiotape data and exit survey (weeks 8–11)—In phase 3, after-hours handover meetings were audiotaped for the last 4 weeks of the clinical term. During the final week of the study, all JMOs completed an exit survey containing seven of the same statements from the baseline survey and an additional four questions specifically addressing ISBAR and the education workshop (table 2).
Data analysis and statistical methods
The pre-ISBAR and post-ISBAR surveys were analysed with a Mann–Witney U test to establish any change in JMO perception of handover.
Each audiotaped handover session was timed, and assessed for adequacy of clinical information communicated according to 19 core data categories (table 3), which were formulated by the study group before study commencement, and a proforma constructed for data collection. All tapes were analysed by two study authors to ensure consensus on data. The pre-ISBAR and post-ISBAR audiotape data were analysed using a two-sample t test to establish any change in the duration of handover per patient as well as any change in the number of key data categories handed over per patient.
All results were externally validated. Significance was accepted at p≤0.05.
Study end points
The primary study end point was JMO perception of an overall change in handover practice following implementation of the ISBAR tool. Secondary end points included change in perception of structure and consistency of handover, confidence in the handover process, and JMO impression on patient care and safety. Secondary end points from the audiotape data included change in the median number of core data categories communicated and change in the average duration of handover per patient.
Forty-four JMOs were rostered to after-hours handover during the study period; 28/44 (64%) completed the baseline survey, and 36/44 (82%) completed the exit survey. 24/44 (55%) participants formally attended the education session, with the provision of recorded educational material to the other participants.
JMO perception on the effect of ISBAR on handover (survey data)
16/27 (59%) of JMOs believed that a poor handover adversely affected their understanding of a patient's clinical picture. 25/35 (71%) of JMOs felt that the ISBAR tool had improved handover and 20/25 (80%) felt the handover workshop improved their skills and confidence in handover.
Following the introduction of ISBAR, significantly more JMOs perceived handover as being consistent, better structured, and with less omission of information occurring (table 4). JMOs felt more aware of the urgency of patient situations and more confident in accepting care of patients handed over to them using the ISBAR format. There was no significant change in perception of whether the amount of information handed over was sufficient to meet their needs, or in the time efficiency of handover with ISBAR. Most participants indicated on the exit survey they felt ISBAR represented a sustainable system 26/36 (72%) that improved patient care and safety 26/35 (74%).
JMOs were also encouraged to provide comments in their survey responses. When asked what was good about ISBAR, sample responses included: “the receiver knows what structure to expect during a handover and it helps to identify missing information” and “it reinforces what is key to a handover”. Among responses regarding the disadvantages of ISBAR was concern about templates being “less flexible” and possibly less appropriate for “simple handovers such as chasing a blood test”. It was suggested that ISBAR template handover sheets should be made available on the wards and in the handover room. One recurring comment was that JMOs would appreciate more constructive feedback from seniors on the quality of their handovers.
Transfer of clinical information (audiotape data)
Following the introduction of ISBAR, handovers showed significantly greater communication of clinical information, with a mean of 10.4 core data categories handed over out of a possible 19 categories, compared to 9.2 categories pre-ISBAR (p=0.004, 95% CI 0.36 to 1.91). Analysis of the change in individual data categories is presented in table 3. Thirteen of the 19 categories were handed over with increased frequency following the introduction of ISBAR, but the increase reached statistical significance in only four of the 19 categories. There was a significant increase in the communication of ward, bed, differential diagnosis, and registrar/consultant to be contacted.
Duration of handover (audiotape data)
The average duration of handover per patient did not significantly change with ISBAR (100.5 s pre- and 101.3 s post-ISBAR, p=0.894).
This study is the first to examine the effects of introducing the ISBAR tool into JMO handover. Our results show that overall JMOs believed handover was improved by the use of ISBAR. They felt more confident in giving and receiving handover, which we would hope translates into improved accountability and responsibility for patient care, a key purpose of handover. Furthermore, JMOs perceived benefits in patient care and safety following introduction of the ISBAR tool. These results are consistent with studies of ISBAR in other settings, where it has been shown to increase communication content, improve the structure and consistency of delivered information, and ultimately enable recipients to feel better prepared with essential information.12 19 20 Several hospitals around Australia are starting to use ISBAR in contexts such as emergency departments, nursing, and inter-hospital transfers.
This study also showed that ISBAR is time neutral, with no change in the duration of individual patient handovers. A time efficient handover tool is important for the uptake of ISBAR into a real clinical setting. A study on the use of ISBAR in telephone communication also found that it was time neutral,19 and it has been shown to reduce the duration of nursing handover.21
Overall, the mean number of core data categories handed over increased significantly following the introduction of ISBAR, suggesting greater communication of key clinical information. Of the four categories reaching statistical significance, improved handover of differential diagnosis and who to contact were regarded by JMOs as having the potential to improve patient safety. Nine other categories showed a trend towards increased handover but did not reach statistical significance, perhaps because they already showed high frequency of handover at baseline (ie, they were already being handed over well). Categories such as resuscitation status and pending test results, which were handed over with low frequency at baseline, did not show noticeable change following ISBAR introduction, which may be because they are not always relevant to a patient's current situation.
The study group chose 19 core data categories as a marker of data transfer. These categories conform to minimum datasets for clinical handover,22 and also cover key areas of inadequate handover which have been identified in studies in US hospitals.5 9 Use of these categories to measure the overall quality of handover (a sophisticated and complex skill) carries some imprecision, and an increase in total information does not necessarily equate to improved patient care. This study was not designed to assess whether the ISBAR tool improves clinical outcomes, and a much larger study would be required to correlate a change in handover practice with a decrease in hospital adverse event reporting. One study that did attempt to link improved communication to reduced rates of adverse events found that after implementation of ISBAR, the rate of adverse events was reduced from a baseline of 89.9 per 1000 patient days to 39.96 per 1000 patient days.14
It was gleaned from the JMO feedback and comments in this study that JMOs value handover education and desire more constructive feedback from seniors during handover. Despite this, study authors were perplexed by the poor attendance at the education session run as part of this study, even though those who did attend commented they found it beneficial. The reasons for the poor attendance are multifactorial, including competing clinical demands and a lack of awareness about the importance of handover, and reflect the practical difficulties of implementing education programmes in a hospital setting. In addition, in an attempt to demonstrate a realistic effect of ISBAR which could be replicated in other hospital settings, we encouraged use of ISBAR through posters and lanyards, rather than strictly enforcing its usage.
Other limitations of this study include the small sample size, and the short duration, which may have limited the JMOs' familiarisation with ISBAR, and thus potentially decreases the perceived impact of the tool. However, it was necessary to complete the study within one JMO term to allow the same JMOs to be studied pre- and post-ISBAR implementation. Further research is needed to assess the durability of introducing such a communication tool. Furthermore, handover research and education must also address which patients require handover and involve training from senior clinicians.
In conclusion, the ISBAR communication tool improved JMO perception of after-hours handover in a time neutral fashion. An education session on the ISBAR tool is an effective, low cost intervention which can lead to significant improvements in JMO handover without disturbing other established practices within the hospital. We consider that this supports the introduction of handover education as a part of medical student and JMO training, and consideration should be given to implementation of the ISBAR tool in all JMO handover settings.
