Abstract

Background Intentional rounding (IR) is a structured process whereby nurses conduct one to two hourly checks with every patient using a standardised protocol.

Objective A realist synthesis of the evidence on IR was undertaken to develop IR programme theories of what works, for whom, in what circumstances and why.

Methods A three-stage literature search and a stakeholder consultation event was completed. A variety of sources were searched, including AMED, CINAHL, MEDLINE, PsycINFO, HMIC, Google and Google Scholar, for published and unpublished literature. In line with realist synthesis methodology, each study’s ‘fitness for purpose’ was assessed by considering its relevance and rigour.

Results A total of 44 papers met the inclusion criteria. To make the programme theories underpinning IR explicit, we identified eight a priori propositions: (1) when implemented in a comprehensive and consistent way, IR improves healthcare quality and satisfaction, and reduces potential harms; (2) embedding IR into daily routine practice gives nurses ‘allocated time to care’; (3) documenting IR checks increases accountability and raises fundamental standards of care; (4) when workload and staffing levels permit, more frequent nurse–patient contact improves relationships and increases awareness of patient comfort and safety needs; (5) increasing time when nurses are in the direct vicinity of patients promotes vigilance, provides reassurance and reduces potential harms; (6) more frequent nurse–patient contact enables nurses to anticipate patient needs and take pre-emptive action; (7) IR documentation facilitates teamwork and communication; and (8) IR empowers patients to ask for what they need to maintain their comfort and well-being. Given the limited evidence base, further research is needed to test and further refine these propositions.

Conclusions Despite widespread use of IR, this paper highlights the paradox that there is ambiguity surrounding its purpose and limited evidence of how it works in practice.

Introduction

In 2013 the Francis Inquiry1 examined evidence about the reasons for failures in patient care at Stafford Hospital, UK, and made recommendations for improvement. One of these recommendations was that ‘regular interaction and engagement between nurses and patients and those close to them should be systematised through regular ward rounds’ (p1510).1 This recommendation has become synonymous with ‘intentional rounding’ (IR), a structured process developed in the USA and marketed by the Studer Group,2 whereby nurses carry out one to two hourly checks with every patient using a standardised protocol and documentation (box 1).

Box 1

Typical intentional rounding schedule in acute ward settings2 5

During each round, the following standardised protocol is used by a nurse for each patient:

  • An opening phrase is used by the nurse to introduce his or herself and to put the patient at ease.

  • Scheduled tasks are then performed.

  • A discussion of the four key elements of the round, often called the ‘4 P’s’:

    • Positioning—making sure the patient is comfortable and assessing the risk of pressure sores.

    • Personal needs—assessing patients’ personal needs, including whether they need assistance with getting to the toilet.

    • Pain—asking patients to rate their level of pain on a scale of 0–10.

    • Placement—ensuring any items a patient needs are within easy reach.

  • An assessment of the care environment, such as checking the temperature of the room or any fall hazards.

  • Ending the interaction with a closing phrase such as “Is there anything else I can do for you before I go?”.

  • The patient is informed of when the nurse will return.

  • The nurse documents the round.

If patients are unable to respond during the round, the nurse may follow this process with family members.61

The UK government’s response to the Francis report expected all National Health Service (NHS) hospitals to implement IR within 1 year,3 4 reinforced by a ‘comply or explain’ approach used in Care Quality Commission hospital inspection,4 and as a result IR has been introduced in the majority of hospitals. A number of benefits have been claimed, including a reduction in call bell use, falls and pressure sores, and increased patient satisfaction.2 5–8 However, substantial limitations to this evidence base have been highlighted, including concerns around selection bias, potential conflict of interest, and weaknesses in study design and analysis,3 9 10 which may, in part, be due to what Marshall et al11 would say is the urge to act combined with the absence of a scientific approach to improvement science.12 In line with recommendations for evaluative approaches in improvement science advocated by Don Berwick,13 for this study we adopt a realist evaluation14 approach to investigate the impact of IR in hospital wards on organisation, delivery and experience of care.15 For the first phase of this evaluation, a realist synthesis of IR was undertaken with the view to develop programme theories to provide a framework for the analysis.

Box 2

Definitions of realist terms and how they have been used in this review

Context (C): This refers to ‘the ‘backdrop’ of programmes and research…broadly understood as any condition that triggers and/or modifies the behaviour of a mechanism’ (p317).62 Mechanism (M): ‘…mechanisms are underlying entities, processes or structures which operate in particular contexts to generate outcomes of interest’.63 More specifically, ‘…mechanisms are a combination of resources offered by the social programme under study and stakeholders’ reasoning in response. 14

Outcome (O): The outcome is a result of the interaction between a mechanism and its triggering context.

Programme theory: The programme theory specifies what is supposed to be done in a policy or programme (theory of action) and how and why that is expected to work (theory of change).18

Realist synthesis is a theory-driven approach to evaluating complex social interventions such as IR, using empirical evidence from the literature.16 17 Realist synthesis seeks to understand for whom the intervention works and does not work, how, why and in what circumstances.17–19 It does this by identifying the relationships between particular contexts, mechanisms and outcomes (known as ‘context-mechanism-outcome configurations’ or ‘CMOs’) at a granular level, which explain an intervention’s successes and failures.16 18 20

As available theory on the potential of IR was limited, the aim of this realist synthesis was to help develop programme theories of IR to generate hypotheses around for whom IR may or may not work, in what circumstances and why.

Methods

Given that this was the first phase of a larger realist evaluation study, realist synthesis was deemed to be the most appropriate method to use for the initial period of theory development, as it applied a realist approach to retrospective literature reviewing. The realist synthesis was undertaken following practical ‘how-to’ guidance in the field,17 18 and the authors ensured that quality and publication standards in realist synthesis were upheld.21 22 It is acknowledged within the field of realism that a number of different conceptualisations or definitions of ‘mechanisms’ have been identified.18 Box 2 provides definitions of how we have used the Context, Mechanism, Outcome and Programme theory terminology in this review.

The realist synthesis was undertaken using a three-stage literature search and a stakeholder consultation event. In stage 1, a search of academic, policy and grey literature was undertaken to develop initial programme theories of IR (ie, purported ideas of ‘what is supposed to happen?’ or ‘how is it supposed to work?’).18 Expert advice was sought from library and information sciences specialists around generating relevant search terms. Between June and July 2014, four electronic databases were searched (Allied and Complementary Medicine Database (AMED), Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medical Literature Analysis and Retrieval System Online (MEDLINE), Royal College of Nursing Archive (RCN Archive), alongside searches of Google, Google Scholar, InterNurse, Science Citation Index Expanded (SCIE) and NHS Evidence, using the strategies highlighted in box 3.

Eighty-nine relevant documents were identified and divided between two researchers. One researcher read all the empirical research papers (n=42) and the other read all the grey literature and policy documents (n=47). Both independently examined their documents to identify any purported mechanisms of IR (ie, theories or assumptions about why/how IR worked/was expected to work). Each wrote a brief description of the mechanism based on what they had found and recorded the names of the papers in which they were identified. The researchers then met to discuss their findings. Eight potential mechanisms were identified in the empirical research papers, and six of these mechanisms were also identified in the policy documents (see table 1). Where both researchers found a similar mechanism, they each briefly described what they had found and combined these descriptions together to produce the mechanism names and joint definitions. When mechanisms were only identified by one researcher, the other also read the paper(s) in which they had been identified and provided their input into the mechanism name and description. Through consensus, a combined list of eight mechanisms of IR was produced (table 1). A similar process was undertaken for context (table 2) and outcomes (table 3).

Between October and November 2014, the stage 2 search was undertaken to refine programme theories by identifying empirical research that either supported or refuted them or identified any new ones. A comprehensive search for empirical research was undertaken in databases AMED, CINAHL, MEDLINE, PsycINFO, HMIC, Embase, Scopus, RCN Archive, InterNurse, BMJ Journals and the Cochrane Library using the search strategy highlighted in box 3. Snowball searches and citation searches in CINAHL and Scopus were also conducted. Nine new research papers were identified and combined with the 42 empirical research papers identified in stage 1. A bespoke structured data extraction form was completed for every paper, recording either salient details on the study design, objectives and participants, or the reason for its exclusion. Broad inclusion criteria were applied, meaning that if a paper described nursing rounds occurring every 2 hours or less and highlighted empirical evidence of any associated context, outcome or mechanism, it was included. Due to constraints in the study’s time and finances, it was necessary to focus the scope of the review on IR alone, rather than cross disciplinary boundaries or seek out data from alternative interventions, which might have the same mechanisms in operation.17 22 Conventional approaches to quality appraisal were not used and instead each study’s ‘fitness for purpose’ was assessed by considering its relevance and rigour.16 23 That is, in line with realist methodology, studies were not appraised by their study design but by whether or not they contributed to theory building and were credible and trustworthy.17 18

Thirty-five papers met the inclusion criteria and were included in the synthesis at this stage. The evidence collected from these papers was synthesised by drawing together all information on contexts, mechanisms and outcomes. Similarities and differences in findings were sought to build a comprehensive description of each mechanism and its role in IR. Due to the small number of papers identified for the ‘patient empowerment’ mechanism, focused literature searches specifically for this mechanism were also conducted, although no new papers were identified. A stakeholder consultation event was held in February 2015, involving service user representatives and NHS clinical staff (n=28), to discuss the mechanisms, contexts and outcomes arising from the synthesis, to ensure none had been missed, and to decide whether or not the researchers should focus only on particular mechanisms or to continue the synthesis with a broader focus.22 The stakeholders felt that the synthesis was appropriately focused to achieve optimal end-user relevance and that further refinement was not required at this stage. A third and final search of the literature was undertaken in February 2016 to ensure the synthesis was up-to-date and that no research published in the interim period had been missed. Stage 2 searches were repeated but focused only on research published between December 2014 and February 2016. Snowball searches and hand searches were undertaken and a further nine relevant papers were identified (44 papers in total, 1 early online). Data extraction forms were completed for each newly identified paper and any evidence added into the hypothesised CMOs.

Results

A document flow diagram for the synthesis process is provided in figure 1. The 44 papers were drawn from reports published in high-impact peer-reviewed journals (n=18), the professional press (n=21), four study reports and a doctoral thesis. The papers referred to research undertaken primarily in the USA (n=25), followed by the UK (n=12), Australia (n=5), Canada (n=1) and Iran (n=1). The papers were published between 2006 and 2017, with a peak in publication in 2012. The two earliest published papers (2006 and 2007) were authored by Meade, who was directly connected to the Studer Group, and these papers were heavily cited by authors publishing at later dates. The 44 papers were written by a total of 168 authors, with only 3 authors (Meade,7 24 25 Braide6 26 and Neville27 28) authoring or coauthoring more than one paper. This suggested there had not been a major programme of research or ongoing interest by one group of researchers in IR.

The programme theories for each of the eight mechanisms are presented below and then the CMOs summarised in table 4. It must be noted that these programme theories were not mutually exclusive, with one context and/or mechanism feeding into another or becoming an outcome of a third; however, they have been separated here for clarity. We will explore enabling contexts, which trigger or change the behaviour of these mechanisms, those contexts that act as barriers and how these CMO configurations may be linked, within the subsequent phase of this realist evaluation study.15

Table 4

Summary of eight context-mechanism-outcome (CMO) configurations

CMO 1: Intentional rounding ensures that consistent and comprehensive care is delivered to all patients by all nurses (n=21)

Twenty-one papers addressed this mechanism,6 8 28–46 highlighting the link between IR and consistent and comprehensive care. The structured, systematic approach to IR prompted and guided the delivery of care, helping staff remember to conduct all aspects of care on every round38 41 and identify tasks that might otherwise be missed.36 The format ensured continuity of care across staff members, helping guide junior/unqualified staff and those less familiar with patients.38 It also enabled persistent problems to be more readily identified, reducing the risk of repeating interventions that were not working.6 However, in most studies there was recognition that a dependence on routinisation and standardisation did not always ensure successful IR and that a flexible approach to process and design may be more appropriate.28 31 33 34 43 46 This involved nurses using their clinical judgement to modify the rounding process, assessing patients on an individual basis and making informed choices about how frequently to conduct rounds and what questions to ask.6 28 30 33 34 38 42 44 45 For example, there was evidence that nurses ‘rounded’ high-risk/high-need patients more and low-risk/low-need patients less regularly than rounding protocols stated.28 33 34 37 42 44 Setting of care was an important context for this mechanism, with reports that hourly rounds could be disproportionate for patients in mental health wards who had been assessed as low risk38 or intrusive for those experiencing psychotic symptoms.42 Other contexts that made IR more difficult included time limitations, low staffing levels and conflicting priorities.28 39 40 44

CMO 2: Intentional rounding gives nurses allocated ‘time to care’ (n=19)

Nineteen papers addressed this mechanism6 7 24 25 28 31 32 34 36 38–41 44 46–50 and the original definition was only partially supported. There was no indication that nurses were given specifically allocated time in which to conduct IR. That is, there was no discussion of where nursing workload had been reduced or extra resources provided in order to assist with IR. However, there was some evidence that IR enabled nurses to manage their time more effectively, which could, in turn, free up more ‘time to care’.36 38 40 A reduction in call bell use following the introduction of IR was also reported to result in nurses having more time for patient care.7 No other descriptions of the mechanism in action were highlighted, and reported outcomes of the mechanism were limited, although it was proposed that the additional time generated by IR improved staff satisfaction,7 24 aided reflective practice38 and was satisfying to patients.40

There was more empirical evidence regarding the absence of the mechanism, with some staff reporting IR was ‘nothing new’, was what they were already doing or made little/no difference to their practice.25 31 34 38 39 50 Others believed IR resulted in less ‘time to care’ and increased their workload.6 31 34 46 50 Completing IR documentation was felt to take nurses away from patient care,31 with some having difficulty fitting IR around the rest of their workloads and ensuring it occurred at the correct time.32 44 46 In these situations, higher priority duties would take precedence over routine rounding49 and more complex patients prioritised over those deemed to be ‘well’.6 28 44 48 Few contexts associated with the mechanism were identified, although the need for cultural change to embed IR within existing routine practices within an organisation was perceived important to its success,6 31 38 47 48 as was successful teamworking.28

CMO 3: Intentional rounding increases nurses’ accountability for the standard of care provided (n=19)

Nineteen papers addressed this mechanism6 28 33–36 38–47 49–51 and accountability (both personal and organisational) was perceived by some to underpin IR.36 38 44 46 47 49 However, the personal accountability of staff generally only related to responsibility for ensuring they completed IR documentation, rather than personal responsibility for carrying out high-quality rounds. Similarly, there were concerns that organisational audits of IR only provided information about staff compliance with documentation procedures rather than providing any record of rounding quality or confirmation that action(s) required had taken place.6 38 39 41 There were concerns that such audits provided incentives for staff to simply ‘tick boxes’ on the documentation rather than completing the tasks in full.35 For example, incidents were reported of nurses completing all documentation at the beginning/end of their shift33 34 38 46 47 or falsifying information on IR documentation when they had forgotten to complete it.46 The suitability of IR documentation was an important context for this mechanism, with evidence that, where documentation was not ‘fit for purpose’ or where rounding required nurses to complete additional paperwork, non-compliance with IR protocols was more likely to occur.28 38–40 45 Leadership and management support was also an influencing factor.34 36 38 43–45 Few studies discussed the outcomes of the mechanism, but some did report that nurses felt patronised, insulted or untrusted,39 44 46 50 while others felt IR devalued nursing work.46

CMO 4: Intentional rounding enhances nurse–patient communication and/or relationships (n=17)

Seventeen papers addressed this mechanism6 24 25 28 31 34 35 37 38 40 41 43 44 46 52–54 and the original definition was partially supported. With regard to nurse–patient communication, it was widely reported that IR increased the amount of time nurses spent in direct contact with patients/family members and thereby increased the frequency of their communications.25 31 38 40 41 43 52 Staff believed that more frequent communications were welcomed by patients and family members,6 25 31 37 making them feel more involved in their care,31 empowered,38 40 more likely to voice concerns25 and less likely to feel ignored/neglected.40 However, there was less evidence that IR improved the quality of communications between nurses and patients/family members. Some staff felt using predetermined IR scripts stripped nurse–patient communications of authenticity and routinised patient contact.46 Some patients also highlighted the importance of quality interactions with staff, noting the importance of meaningful contacts and feeling connected.35 40 53 The second aspect of this mechanism related to nurse–patient relationships, and there was some evidence that these could be improved through IR. Some staff reported IR helped them get to know patients better,40 making them more aware of their needs,25 31 34 which could potentially impact on patient outcomes.31 It was felt this improved knowledge could also lead to better teamworking, enabling staff to hand over more detailed information about patients to the next shift.40

CMO 5: Intentional rounding increases nurse visibility (n=11)

Eleven papers addressed this mechanism6 25 26 31 34 36 40 41 43 44 48 and some staff did believe IR increased the visibility of nurses on a unit.25 34 Increased visibility was generally viewed positively by nurses, with perceived benefits such as enhanced nurse–patient communication,31 helping patients feel well cared for and increased staff satisfaction.43 However, some negative outcomes were also reported, including an increase in non-urgent requests from patients.48 Some nurses questioned any association between IR and increased visibility, believing they were visible to patients even when they were not undertaking rounds. They could not, however, confirm whether this was also the patients’ perception.40 Of the studies that did explore patient perceptions, it was generally agreed that increased visibility of nursing staff was valued.6 26 36

CMO 6: Intentional rounding enhances nurses’ ability to anticipate and proactively address patient needs (n=11)

Eleven papers addressed this mechanism27 29 30 36–38 40 41 44 46 47 and there was some empirical evidence to support the original definition. A number of staff stated IR enabled them to be proactive in anticipating patient needs, as opposed to being reactive to patient call bells/requests for help.30 36 37 44 46 47 This was associated with increased patient satisfaction30 and reassurance,37 38 decreased patient anxiety,37 a reduction in call bell usage,38 40 resulting in an overall sense of calm on the ward,38 and decreased staff workload.46 IR was also reported to enable nurses to intervene earlier when a patient’s medical condition was deteriorating, potentially preventing the need for higher levels of medical intervention37 and could prevent quieter patients being overlooked.38 40 46 Fewer studies reported patient experiences of the mechanism, although patient questionnaires demonstrated improvement in patient satisfaction27 and perceptions of nursing proactivity following the implementation of IR.40 One context associated with the mechanism was the type of patient and their particular needs. For example, changing position and getting in and out of bed were identified as activities that could be anticipated and addressed by IR but not pain management or toileting needs.29 The layout of the ward was also noted as an influencing context, with IR helping ensure patients in side rooms were not forgotten.41

CMO 7: Intentional rounding enhances staff communication and/or teamworking (n=9)

Nine papers addressed this mechanism,25 28 30 32 36 40 42–44 with a number discussing the interconnecting relationship between staff communication and IR. That is, strong staff communication was perceived to be crucial for effective rounding, and rounding was perceived to improve staff communication.32 36 40 42 43 A similar relationship was also identified between IR and staff teamworking.25 28 36 44 When staff communication and teamworking were deemed to be ineffective, this caused frustration and concern among staff and reduced the effectiveness of IR.28 44 Contexts influencing the mechanism were staff involvement and ownership of practice32 43 and the busyness of the ward.30

CMO 8: Intentional rounding fosters patient empowerment (n=4)

Four papers addressed this mechanism,27 31 38 40 although evidence was primarily drawn from one UK study.38 This reported patients becoming more ‘forthcoming’ when they knew staff were coming to see them regularly, empowering them to ask for what they needed. As in the original definition, this study also identified patient empowerment to be closely entwined with nurse–patient communication and relationships.38 Tentative evidence related to patient empowerment as an outcome of IR was identified by three studies.27 31 40

Influencing contexts and outcomes of IR

While the aim of realist synthesis is to better understand the interplay of how a particular context has an impact on a specific mechanism to produce outcomes,18 the review highlighted that such detailed theoretical explanations are rarely provided in the IR literature. We elicited a list of potential ‘backdrops’ believed by authors to influence IR and a list of potential outcomes reported to arise from it. These are highlighted in tables 2 and 3, respectively. The findings of this synthesis echo those of a systematic review of the barriers to effective implementation and sustainment of IR on medical and surgical wards,55 as well as identifying additional ones. In table 4, we make explicit the theories by which IR may work by summarising the CMO configurations to be tested and refined in the subsequent realist evaluation phase of the study.15

Discussion

In line with authoritative views on improvement science,12 13 our realist synthesis aimed to develop programme theories of IR to explain how, why, in what circumstances and for whom IR may or may not work. We interrogated the evidence in order to generate hypotheses, test and refine in the subsequent phases of our realist evaluation study. In a review of health improvement research in the UK, Dixon-Woods et al56 argued that extensive development periods are needed to specify programme theory and select appropriate frameworks for analysis. It was notable that many studies included in the synthesis illustrate the absence of theoretical development as they only reported outcomes of implementing IR without providing any explanation of how or why they occurred. Similarly, many discussed the contexts that influenced IR but failed to explain how these conditions interacted with mechanisms to produce specific outcomes. This highlights the minimal theoretical explanations of IR that have been identified to date and the ambiguities surrounding its purpose. This poor understanding of how IR works poses a major challenge to learning, replication and sustainability of the intervention, and supports the work of others in this field.11 56

The synthesis identified a number of discrepancies between how IR is purported to work and how it operates in practice, as well as international differences in how the intervention has been implemented. For example, guidance from the USA states that the structured approach is a fundamental facet of IR and that the intervention should be used in a standardised manner so that all patients receive the same input.2 Yet other countries, including the UK, appear to have adopted a more flexible approach, based on nurses’ clinical judgement of patient need and preference. This is arguably because of differences in the drivers of implementation of IR in both countries. In the USA, IR is a marketed product,2 implemented in response to patient satisfaction surveys determining hospital financial reimbursement.57 However, in the UK, the Francis Inquiry was the major impetus for the widespread adoption of IR, with the aim of providing reassurance to the public at a time of intense media pressure. The UK government has been criticised for promoting IR and urging its introduction within NHS hospitals without being clear on what they were promoting and with no directives on how it should be undertaken or recorded.3 9 The intervention has therefore not been consistently implemented across settings but refined and adapted to suit local circumstances. It is not yet clear whether this flexible approach to IR has had a positive or negative impact on outcomes in the UK. What is clear, however, is that, both nationally and internationally, the intervention that one organisation refers to as IR is not the same as another, nor the same intervention that other empirical studies have evaluated. This leads to an important question of how flexible the approach to the delivery of IR can be before it can no longer be considered IR.

Another distinction between theory and practice of IR was highlighted in the ‘allocated time’ mechanism. While it has been claimed by some that IR would give nurses assigned time to care for patients’ basic needs, in the empirical literature, there was no evidence that nursing workload had been reduced or extra resources provided in order to assist nursing staff in carrying out IR. This is likely because, in practice, IR is not seen as a ‘time-requiring intervention’ but as fundamental care which should already be being done. It is little surprise, therefore, that many nurses felt IR was ‘nothing new’ or that it replicated what nursing staff had always done, but with added documentation. The ‘nurse-patient communication and relationships’ mechanism emphasised additional discrepancies by highlighting that IR may increase the frequency of nurse–patient communication, but not necessarily improve its quality. It is conceivable that increasing the frequency of nurse–patient communication alone could safeguard patients in settings where care delivery is poor. For example, reported instances of neglectful care, such as patients not being offered food, drink or pain relief for ‘many hours’ (point 7.314, p662),58 should not occur with an intervention that requires nurses to check these needs at hourly intervals. It is less apparent, however, whether simply increasing the frequency of nurse–patient communication would offer any further benefit to highly performing units or whether this might indeed reduce standards of care by taking nurses away from other key tasks and duties. This synthesis has established that, for many patients, increasing the frequency of communication alone is not enough and that it is the quality of their interactions with nurses that matters. This demonstrates the tensions around standardising nursing input within IR instead of accounting for the different needs of patients in order to provide interactions that are meaningful to them.

Managing risk has also been acknowledged as an important driver for the introduction of IR, and assumptions have been made that IR will increase the personal accountability of nurses and raise the overall standard of nursing care. However, this synthesis has identified that this is not necessarily the case. IR may assist organisations to monitor and audit the care provided by their nursing staff, but evidence suggests that these audits focus on compliance with documentation procedures rather than on the quality of rounds. Such focus on compliance with documentation is not necessarily a bad thing depending on whether or not the information gathered can be used by nurses to improve the care they deliver. However, there was evidence these audits provided incentives for staff to simply ‘tick boxes’ on the documentation, which could result in inaccurate records offering little protection to patients. This illustrates another ambiguity in the purpose of IR—is it to support nurses to improve the care they deliver, provide nursing managers with detailed evidence of nursing activity (eg, to support complaint handling), or is it an assurance tool for nurse directors seeking to report the quality of care to their boards and the public? This and other questions raised by this synthesis will be explored in subsequent phases of the upcoming realist evaluation in order to further refine and develop theories of IR.15

The weak evidence also did not give sufficient justification for the implementation of IR in the UK. Nevertheless, IR has been widely implemented and therefore the subsequent realist evaluation will focus on testing how contexts, mechanisms and outcomes of IR are configured.

Strengths and limitations

This review has shown how IR may work by identifying the programme resources that the intervention offers and how these may be interpreted and acted upon by patients, carers and staff. It has specified how each of these mechanisms may or may not be triggered by different contextual factors and lead to a range of desired outcomes. The clinical outcomes included in this synthesis were specified in the protocol, for instance, call bell use, falls and pressure sores, but this review has also identified experiential outcomes, for example, empowerment, patient and carer satisfaction, and patient awareness of IR. Few studies included patient perspectives of IR.

The main limitation of this realist synthesis study was lack of robust evidence relating to IR and specifically the few insights about how IR was expected to work. The 35 of the 44 included studies which attempted this tended to be small, locally based evaluations, many of which relied on staff self-report or routinely collected data. IR outcomes included self-reported patient and staff outcomes, clinical outcomes, health economic and hospital-reported patient outcomes, but the predicted direction of change was not always clear-cut. Of the available evidence, only call bell use; patient, carer and staff satisfaction; pressure ulcers; patient falls; and patient complaint outcomes had a consistent pattern in the direction of change predicted by the majority of included studies, but these had serious methodological and/or reporting weaknesses, so should be treated with extreme caution.

Conclusion

Despite the widespread use of IR, this paper highlights the paradox that there is ambiguity surrounding its purpose and limited evidence of how it works in practice. Our conclusions generate, first, understanding of how IR works in relation to context and outcomes; second, clarification of international differences in the drivers behind its implementation; and finally, learning for replication and sustainability of IR. Differences in the implementation of IR identified in the evidence demonstrate the importance of care delivery context and potentially that IR has been adapted in different contexts and over time.16 59 IR has been described as a ‘search for simple solutions to complex problems’,60 and it has been acknowledged that IR should not be perceived as a panacea to all problems.61 The findings of this synthesis agree with both points. It would appear, for example, that IR may well be an appropriate intervention to achieve particular goals (eg, increasing the visibility of nursing staff and frequency of nurse–patient communication) but less appropriate for others (eg, empowering patients or improving the meaningfulness of nurse–patient interactions). Further research is needed to test the eight a priori propositions about how IR may work, for whom, in what circumstances and why, and whether the investment of resources to support IR offers good value for money.
