How do stakeholders experience the adoption of electronic prescribing systems in hospitals? A systematic review and thematic synthesis of qualitative studies.

BACKGROUND: Electronic prescribing (ePrescribing) or computerised provider/physician order entry (CPOE) systems can improve the quality and safety of health services, but the translation of this into reduced harm for patients remains unclear. This review aimed to synthesise primary qualitative research relating to how stakeholders experience the adoption of ePrescribing/CPOE systems in hospitals, to help better understand why and how healthcare organisations have not yet realised the full potential of such systems and to inform future implementations and research.
METHODS: We systematically searched 10 bibliographic databases and additional sources for citation searching and grey literature, with no restriction on date or publication language. Qualitative studies exploring the perspectives/experiences of stakeholders with the implementation, management, use and/or optimisation of ePrescribing/CPOE systems in hospitals were included. Quality assessment combined criteria from the Critical Appraisal Skills Programme Qualitative Checklist and the Standards for Reporting Qualitative Research guidelines. Data were synthesised thematically.
RESULTS: 79 articles were included. Stakeholders' perspectives reflected a mixed set of positive and negative implications of engaging in ePrescribing/CPOE as part of their work. These were underpinned by further-reaching change processes. Impacts reported were largely practice related rather than at the organisational level. Factors affecting the implementation process and actions undertaken prior to implementation were perceived as important in understanding ePrescribing/CPOE adoption and impact.
CONCLUSIONS: Implementing organisations and teams should consider the breadth and depth of changes that ePrescribing/CPOE adoption can trigger rather than focus on discrete benefits/problems and favour implementation strategies that: consider the preimplementation context, are responsive to (and transparent about) organisational and stakeholder needs and agendas and which can be sustained effectively over time as implementations develop and gradually transition to routine use and system optimisation. © Author(s) (or their employer(s)) 2019.

Introduction

The medication use process in hospital settings is generally understood to comprise four interrelated stages: prescribing, dispensing, administering and monitoring.1 In practice, these involve a broad range of health professionals, documents, practices, situations, settings and multiple inter-related processes, the interplay of which can give rise to several risks and errors with the potential to result in patient harm.2–5 Electronic prescribing (ePrescribing) or computerised provider/physician order entry (CPOE) systems can improve patient safety and the quality of health services by reducing risks associated with medication errors6–8 and by improving organisational efficiency and health professionals’ performance throughout the medication process.7 9

However, the translation of such improvements into reduced harm for patients is still unclear.8 10 It has become increasingly clear that the implementation of ePrescribing/CPOE systems may create unintended consequences and introduce new safety issues once in use.9 11–15 In this context, in light of the inherent complexity of the medication process and the difficulty of examining it in isolation from other interrelated processes and contextual factors, a growing body of qualitative research has provided insights into key implementation and use issues concerning ePrescribing/CPOE systems in hospital settings9 16–23 for nearly two decades.24 An interpretative examination of such body of qualitative evidence would enable better understanding of why and how healthcare organisations have not yet realised the full potential of such systems and would inform future implementations and research. With this motivation, we conducted a systematic review of qualitative studies addressing the following question: how do stakeholders experience the adoption of ePrescribing/CPOE systems in hospitals?

We aimed to identify, collate, assess and synthesise primary qualitative research relating to the perceptions and experiences of those involved in, or affected by, the implementation, management, use and/or optimisation of ePrescribing/CPOE systems in hospital settings.25

The review has three important elements absent from previous attempts to synthesise primary qualitative research on this topic26: (1) it employs an interpretative (rather than aggregative) analytical approach; (2) it draws on all reported stakeholders’ perspectives, not just those of health professionals; and (3) it includes research at any stage of ePrescribing/CPOE adoption, from implementation through to routine use.

This is of particular importance given the complex, sociotechnical nature of ePrescribing/CPOE systems and the inherent difficulty of establishing the end-point of the implementation process. Implementation is generally understood as the transitional period or set of activities between the organisational decision to adopt an intervention and the point at which it becomes assimilated as routine use.27–29 This separation is not straightforward for interventions with such complexity: this judgement is multifaceted, highly contingent on multiple perspectives and context dependent. Overlaps between system implementation, routine use and system optimisation issues across settings and organisations are integral in the literature. Therefore, an interpretative examination of ePrescribing/CPOE across studies is important in that it enables incorporation of multiple perspectives and accommodation of a wide range of conceptualisations about the implementation process, in a holistic analytical approach.

Methods

We registered and published a peer-reviewed protocol25 following ENTREQ guideline recommendations,30 adopting systematic search methodology and thematic synthesis.31

Search strategy

The following bibliographic databases were searched from inception to October 2018: MEDLINE, MEDLINE In Process, Embase, PsycINFO, Social Policy and Practice, CINAHL, The Cochrane Library (CDSR, DARE and CENTRAL databases), Nursing and Allied Health Sources, Applied Social Sciences Index and Abstracts and Scopus. Additional sources were Sciences and Social Sciences Citation Index and grey literature (Healthcare Management Information Consortium, Conference Proceedings Citation Index and Sociological Abstracts). Citations in relevant reviews and included studies were checked. Selected specialist journals were hand searched.

A comprehensive search strategy was developed, employing a combination of search filters,32 33 text words and index terms relating to qualitative research and relevant interventions, including variations and permutations used in similar reviews7 26 34–36 with no restriction on date or language. The sample strategy in online supplementary appendix 1 was adapted for each bibliographic database.

Inclusion criteria

Qualitative studies (standalone or within mixed-methods designs) exploring stakeholder perspectives/experiences of implementation, management, use and/or optimisation of ePrescribing/CPOE systems in hospitals were included. Any electronic system or subsystem involving the prescription and/or administration phase of the medication process were included. Electronic systems involving other phases of the medication process (eg, systems for stock control) but not prescribing were excluded. Where CPOE systems allowed the ordering of anything other than medication, studies were excluded unless findings specific to medication were reported separately. Any types of participants/perspectives (eg, doctors, nurses, managers, service users and IT staff) were eligible. Eligible settings included hospital-based care settings (eg, wards, clinics, areas, specialities or whole organisations). All articles were independently screened by two reviewers. Discrepancies were resolved by discussion until consensus was reached.

Quality appraisal

Quality appraisal of included studies was conducted using a tool (online supplementary table 1) derived from the Critical Appraisal Skills Programme Qualitative Research Checklist37 and the Standards for Reporting Qualitative Research.38 The methodological quality of each study was independently appraised by two reviewers. Disagreements were resolved by discussion until consensus was reached. Acknowledging the inherent difficulty of appraising all aspects of quality of qualitative research,39 studies were not excluded based on the quality/adequacy of the reporting. Instead, the quality of studies was taken into consideration during data synthesis40 by exploring whether any particular finding or group of findings were dependent, either exclusively or disproportionately, on one or more studies classed as ‘low-quality’ or ‘inadequately reported’.

Data extraction

Articles were read in full before data were extracted and recorded by two reviewers using a piloted data extraction form (online supplementary table 2). Study findings were all text and tables labelled as 'results' or 'findings' in each article including verbatim data extracts from participants and authors’ descriptions, summaries and interpretations of primary data. Extracted data were imported into NVivo V.11 to assist the coding, data management and data synthesis process.

Data synthesis

Data were synthesised using a thematic synthesis approach31 with three overlapping interrelated stages: (1) line-by-line coding of the findings; (2) categorisation of codes into descriptive themes; and (3) development of analytical themes to describe and/or explain descriptive themes.

A multiple coding strategy was employed, with the lead author coding the whole dataset and the remaining review team coding subsets to ensure all data were independently double-coded. Regular meetings were held throughout the data synthesis process to carry out reviewer triangulation comparing reviewer codebooks, descriptive/emerging themes and interpretations until a coding framework was agreed. This was then applied to the whole dataset by the lead author and revised and refined with the team. Subsequent meetings focused on: categorisation of initial codes into descriptive themes; development, discussion and agreement of analytical themes and interpretative framework; and discussion, refinement and establishment of final synthesis findings.

Results

Systematic searches yielded 5003 records, which were assessed against the inclusion criteria. Abstract screening resulted in 434 records considered eligible or inconclusive. Full-text articles were then retrieved and assessed for eligibility, with 79 papers included in the final synthesis (figure 1). Included papers reported data from 15 countries (UK=26, USA=25, the Netherlands=9 and Australia=8). Study samples ranged from 10 to 1018 participants. Articles mainly focused on the perspectives of health professionals (in clinical, administrative, technical and leadership roles) with a few including other stakeholders (eg, patients, carers, policymakers or systems suppliers). Study settings included adult and paediatric acute care hospitals, general and community hospitals, medical and surgical wards and hospital-based clinics. Key characteristics of included studies are presented in online supplementary table 3.

Our quality assessment (table 1, online supplementary table 4) concluded that, overall, articles reported valuable research and credible findings. Nevertheless, 29 of the 79 papers did not report or employ any techniques to enhance trustworthiness (such as multiple coding or triangulation) in their data analysis process, adding to the inherent difficulty of appraising the credibility of findings. Only 10 of the 79 papers clearly and explicitly addressed the relationship between researchers and participants, with a further 16 papers providing only some relevant information, adding to the difficulty of evaluating the impact of these aspects on study findings.

Four overarching themes and 10 subthemes were generated from our analysis. Our set of analytical themes did not align with a sequential pattern or predefined stages of implementation/adoption. Included papers rarely stated how ‘implementation’ was understood by researchers or the implementing organisation and, where present, definitions were extremely heterogeneous, ranging from examinations of the process in terms of specific time frames (eg, ref 41) through to its conceptualisation as an ongoing process (eg, refs 42 43). Hence, data were pooled on the basis of patterns of analytical concerns incorporating a wide range of conceptualisations about the implementation process. Table 2 summarises our coding framework, and online supplementary table 5 details the distribution of our themes by included papers. Themes are described below and exemplar data extracts provided in online supplementary table 6.

Contextualising the implementation and impact of ePrescribing/CPOE in hospitals

Factors and/or actions undertaken prior to implementation were highlighted in some studies as important to understand the implementation and impact of ePrescribing/CPOE in hospitals. These illustrate the importance of allocating resources, prior to implementation, to prepare for both the organisational change and its stakeholders for changes in practice competencies and behaviour.

Preparing the organisation for change

A range of organisational factors were highlighted as a key enablers of successful implementation, including: defining an implementation strategy44; planning the change in terms of timescale, deliverability and organisational/structural needs (eg, IT networks and underlying drug database)44–47; understanding current practice and workflows and their variability46 48 49; building a good relationship between hospitals and system suppliers44 46; and being able to design a system to fit the workflow.24

Preparing stakeholders for change

The active involvement of stakeholder groups across the hospital setting was seen as important in ensuring successful implementation. This included accommodating the agendas of multiple stakeholder groups44 46 47 and establishing ad hoc multidisciplinary networks47 to develop pathways48 and appraise service requirements against systems options45 while ensuring that stakeholders’ needs were met.43 44 50

Broader contextual factors such as key policy changes that can trigger or support project initiation47 were also reported as relevant to facilitating and understanding successful implementation of ePrescribing/CPOE systems in hospital settings.

Factors affecting the implementation process of ePrescribing/CPOE systems

Factors positively impacting the implementation process

Top-level leadership and support were seen as key enablers, particularly if they could: bring in an understanding of the wider context and outside pressures within which the organisation was operating43 51–54; establish effective governance strategies to support implementation across the organisation through committees and working groups19 24 47 51 52; and identify and address any anticipated/emerging problems and needs, such as those relating to guidance/pathway/policy development, estimation/identification of resources, setting realistic time frames, workflow/practice changes and training needs.18 19 24 44 49 50 55–57

The availability of leadership roles and/or championing individuals on the ground was also seen as a key enabler42 58 particularly as a way to facilitate longer term success by bringing about engagement16 19 44 48 51–53 59 and support19 46 51 52 56 across stakeholder groups from early implementation. Other engagement/support strategies during implementation included the provision of ongoing training opportunities18 19 24 43 53 56 which, in some cases, were seen to promote a sense of pride in mastering and helping to implement the system across stakeholder groups.48

Piloting and testing the system prior to full implementation was identified as important to ensure safety44 46 55 despite the risks associated with running two systems simultaneously (paper and electronic), typically minimising the transition from pilot to full implementation.44 46

Factors negatively impacting the implementation process

Problems were identified that could emerge during the implementation of ePrescribing/CPOE and hinder or negatively impact the implementation process. The nature of the reported issues was similar across studies, including core technical challenges (eg, appropriate infrastructure and availability of devices, issues relating to the usability of the system, alignment between system functionalities and hospital processes and interoperability issues with other systems in use)41 43 55–57 60–64 as well as personal challenges experienced by stakeholders (eg, insufficient training and support during implementation, fear of change and anxiety associated with expectations, unfamiliarity and inexperience with the newly implemented system and contradictions/conflicts resulting from recently changed roles, policies or pathways).19 41 42 48 56 60 62 63 These were seen as important because they could change attitudes towards the system during implementation16 41 55 and result in significant implementation delays21 55 or even deimplementation.60

Positive and negative implications of ePrescribing/CPOE systems

Positive practice implications

Users’ experiences suggested a positive impact on safety, including a perceived reduction of medication-related incidents and adverse events after implementation,16 65 66 mainly due to improved accessibility9 46 67 and legibility9 19 46 61 68–71 of prescriptions. These benefits were echoed by patients.72 Easy, ‘on-the-spot’ access to detailed and comprehensive patient history information18 52 61 73–75 was also seen as an important benefit, which also improved continuity of care. For implementations involving or consisting of new clinical decision support systems, safety benefits were also linked to the ability to access built-in order sets and information on drugs and doses9 67 73–77 and the system’s ability to prevent dosing errors9 45 47 through an automatic alerting functionality61 78–80 at the time of prescribing.

Other reported benefits of eprescribing/CPOE related to perceived time-saving across the medication process: from faster prescribing and ordering of medications9 18 24 69 75 81 through to faster checking and supply of medicines.46 66 69 70 These time-saving benefits were afforded by a range of aspects brought in by ePrescribing/CPOE, such as the ability to access prescriptions remotely9 18 24 47 48 51 52 61 69 73 74 81 or improved legibility and completeness of prescriptions.24 46 70

Several studies also reported on a range of performance benefits other than strictly time-related efficiencies, including improvement in: coordination and communication,18 42 47 52 70 prescribing accuracy and timeliness67 82 and ability to easily find, prioritise and track orders.9 67 70

Negative practice implications

Most reported negative practice implications involved a range of perceived inefficiencies (eg, excessive complexity of screens to complete prescriptions and having to log in and out of multiple systems) with many increasing task-time across all stages of the medication process9 16 18 51 52 61 67 72 73 79 81–84 and/or increased workloads.9 46 47 49 55 66 69 70 84–86 In some cases system-related inefficiencies were still experienced 1 year after implementation,18 with some perceiving themselves to be back to baseline levels of efficiency at around 2 years postimplementation81 and others considered unlikely to ever return to pre-CPOE efficiency levels.61

The lack of appropriate IT infrastructure to ensure the smooth and responsive functioning of a system (eg, integration of coexisting systems, log-in and screen-loading times, availability of devices to interact with the system and provision of ongoing technical support to users) was seen to have disruptive consequences on health professionals’ workflows after the implementation of ePrescribing/CPOE.9 24 47 48 51 52 61 68 75 80 84 86–88

Negative practice implications were often perceived to counterbalance the benefits of ePrescribing/CPOE from a clinical perspective, particularly where the implementation of ePrescribing/CPOE was also associated with the introduction of new, unintended and often unanticipated safety risks.9 14 18 19 42 43 49 61 63 65 68 71 73 75 76 78 81 83–86 88–93 For example, a number of issues relating to systems’ interfaces and functionalities (such as excessive triggering of alerts, long lists of medication, default dosing functionality, limited dosing scales or forced sequences of field completion and navigation across screens, views and overviews) were perceived to increase the risk of specific errors.

Positive organisational implications

Although most included studies focused on benefits/problems of ePrescribing/CPOE in practice, some highlighted broader organisational issues.

Positive organisational implications had to do with the cost-effectiveness of the monitoring potential afforded by ePrecribing/CPOE technologies for quality and safety assurance purposes45 48 51 52 77 93 alongside its potential for financial efficiency43 55 93 and the positive impact on institutional reputation associated with being seen as a technologically advanced organisation.43

Negative organisational implications

Some studies reported a sense of distrust from clinicians towards some drivers expressed from a managerial perspective. For example, some studies reported clinicians perceiving ePrescribing/CPOE to be more advantageous to managers/administrators and imposed on them rather than driven by genuine clinical needs.51 52 Other studies reported clinicians’ concerns relating to the use of data generated by the ePrescribing/CPOE system for surveillance and performance management purposes.20 77 93

The lack of integration with other existing health information technology systems was perceived as a barrier to effective and reliable information transfer across coexisting systems in hospitals. Moreover, such lack of integration was seen to introduce risks (such as the potential for duplication associated with manual data entry across systems) that can hinder the availability of timely and complete data and compromise the ability of an organisation to realise the full potential of ePrescribing/CPOE systems.23 43 49 51 55

Other perceived problems included a lack of organisational policies, management practices and standards of practice that address/support new or changing procedures and workflows after implementation.66 67 71 86

Mixed impacts and change processes

Beyond the benefits-and-problems rationale employed by most studies to describe the impact of implementing ePrescribing/CPOE in hospitals, papers also reported on what we have called ‘mixed impacts and change processes’, that is, impacts that cannot be easily framed as ‘positive’ or ‘negative’ per se but are better understood as ‘differences’ from whatever there was prior to implementation and as such they have the potential to result in either positive or negative implications, or both (or neither), in different contexts.

Change in practice

The main transformations reported by studies involved changes in work practices, particularly around workflows, interactions and communication:

Workflow-related transformations included changes in aspects such as work pace, sequence and dynamics18 57 81 85 88 93 94 that can reshape the factors leading to medication errors71 95 and impact on many other specific aspects of everyday practice for doctors (eg, changes in the sequence and nature of cognitive tasks physicians undertake when admitting a patient to hospital)96 as well as nurses (eg, ability to document that a medication was given becomes subject to system access and log-in)67 71 and pharmacists (eg, shift in documentation and annotation practices, particularly due to systems’ built-in drug information).70 71 97 98

Interaction-related transformations included a perceived increased interdependence resulting from changes in the frequency, volume and/or nature of staff-staff interactions (eg, between doctors and nurses or between pharmacists and doctors)42 43 47 63 71 83 86 88 98 99 and staff–patient interactions (eg, pharmacist–patient or doctor–patient interactions).16 86 93 98 100

Communication-related transformations included changes in interprofessional communication patterns, task coordination and flow of information (eg, pharmacy–clinician or doctor–nurse communication, communication between administration and clinical staff and communication between shifts)24 43 51 52 65 67 71 74 80 94 101–104 including changes in the educational experiences in teaching/academic hospitals105 as well as changes in patient communication.86 88 98 100 101

These changes, alongside the need to accommodate idiosyncrasies of the systems themselves, were perceived to have shifted professional roles47 63 65 71 79 83 88 95 97 98 102 103 106 107 that often translated into the emergence of a wide range of workarounds9 16 18 22 48 49 51 61 66 74 78 84 88 92 93 108 across all the stages of the medication process.

Change at the organisational level

CPOE/ePrescribing systems were perceived to shift governance practices, bringing in new ways to handle and enact organisational power and organisational politics.43 47 51 52 57 93 For example, choosing a system and devising an implementation strategy can enable those leading on its implementation to influence the distribution of its advantages and disadvantages within the organisation43 by focusing more on particular processes’ or stakeholders’ needs over others (eg, doctors over pharmacists or managers over clinicians).47 51 52 71

Other studies reported how ePrescribing/CPOE systems enable the generation of, and access to, new data and metrics about individuals, teams, services and organisations9 20 47 62 93 to inform service evaluation and improvement, but with the proviso that appropriate strategies and resources for data monitoring, analysis and follow-up had to be in place to enable improvements.62 92 109

CPOE/ePrescribing systems can introduce or highlight discrepancies between established processes/policy/guidelines and practice under the newly implemented system48 64 83 85 92 95 the extent and nature of which are perceived and experienced differently across different clinical contexts.51 52 94 Such gaps were addressed by organisations by either performing modifications to the system to realign practice and processes/policy/guidelines47 66 93 and/or by making adjustments to current processes/policy/guidelines,9 46 66 81 including the temporary formalisation of emerging workarounds to mitigate known system limitations that were perceived as patient safety risks.22

Discussion

We carried out a thematic synthesis of 79 papers to examine how stakeholders experience the adoption of ePrescribing/CPOE systems in hospitals.

Stakeholders’ perspectives revealed a mixed set of impacts that collectively do not clearly frame ePrescribing/CPOE as resulting in either an improvement or a deterioration of the quality and safety of hospital services. Instead, our findings reveal coexisting benefits and problems, which often overlap and counterbalance each other in the context of competing impacts and further-reaching, more complex changes. Taken together, these can be understood as an illustration of cultural shifts that reframe and recast the issues and challenges of the medication-related aspects of quality and safety in hospitals.110 Implementation strategies should explicitly and integrally address the change processes triggered by the adoption of ePrescribing/CPOE, both in practice and at the organisational levels, rather than focusing solely on discrete benefits/problems, recognising such changes are multifaceted, highly contingent on multiple perspectives and context dependent.

To address this, implementing organisations and teams could call on available implementation theories, models and frameworks28 29 to inform their implementation strategies, as well as research specifically addressing change processes and contextual factors involved in the adoption of ePrescribing/CPOE in hospitals. Although studies included in this review have largely focused on benefits/problems of ePrescribing/CPOE rather than the change processes underpinning them, these processes are well documented across included studies (eg, ref 22) and have the potential to inform future implementation strategies through a more comprehensive understanding of the impact of ePrescribing/CPOE.5 71

Only a few studies examined the implementation and impact of ePrescribing/CPOE taking into account factors and/or actions undertaken prior to implementation. However, these would suggest that more attention (and appropriate allocation of resources) to preimplementation considerations,111 112 including appropriate contextualisation of implementation strategies with specific reference to organisational and stakeholder groups needs and agendas, should facilitate successful implementation.44 45 Furthermore, echoing the sociotechnical nature of ePrescribing/CPOE, our findings suggest that assessing and responding to organisational and stakeholders’ needs should be treated as an ongoing, emergent feature of ePrescribing/CPOE adoption.

Our findings suggest drivers for implementing ePrescribing/CPOE in hospitals cannot be straightforwardly explained by the benefits experienced by those involved in their everyday use. Risks and safety concerns have been reported throughout the period covered by this review, in keeping with previous findings.10 While most included studies focused on clinicians’ perspectives, their needs have not been centrally addressed in ePrescribing/CPOE implementations. Conversely, little attention has been paid to the broader organisational issues, including potentially powerful drivers and factors from a managerial or health-systems perspective. Instead, most reported impacts were practice related. An in-depth knowledge of incentives and drivers of a political, financial, corporate or managerial nature could have helped explain why clinicians’ needs may not have been central to ePrescribing/CPOE implementations and contextualise the practice-related impacts of ePrescribing/CPOE adoption in hospitals, so that they can be better understood, explained and researched. It follows that organisational transparency on the intended direction of change in clinical practice and at the organisational level, and seeking, management and balancing of different stakeholder perspectives throughout ePrescribing/CPOE adoption journey, should help implementing organisations to address potential negative implications and promote beneficial contextual factors.

A further research gap was the limited number of studies drawing on patients’ or carers’ views.21 45 62 72 89 100 109 These could provide valuable insights related to key aspects of ePrescribing/CPOE systems in practice, such as shifts in communication/interaction patterns100 and the involvement of patients/carers in medication safety,112 including the examination of ePrescribing/CPOE as a potential barrier to patients/carers accessing their own prescriptions while in hospital. This is needed to understand the impact of ePrescribing/CPOE on enacting patient-centred care, in particular, the fundamental tenet of acknowledging and valuing patients’/carers’ experiential knowledge. Patients, particularly those with multimorbidity and polypharmacy, see their care managed under multiple or changing systems over time and/or across settings. Implementing organisations and teams should seek and address patient and carer views and experiences to ensure patient-centred care is maintained and patient satisfaction sustained during system implementation and optimisation.

Our review has limitations. Variable reporting quality of included papers reduced our ability to consider contextual information about specific settings and/or systems and to accurately assess quality. We did not carry out quantitative inter-reviewer reliability assessments. Instead, we ensured reliability and consistency across reviewers by systematically discussing all disagreements, involving additional reviewers when required to achieve consensus. In this secondary analysis, another important limitation was the restricted access to primary data: our findings draw on authors’ interpretations in articles’ results sections and any illustrative quotes reported to support them. We sought to provide an integrative understanding of ePrescribing/CPOE systems from stakeholders’ experiences drawing on multiple perspectives that have engaged from different angles with similar interventions in secondary care contexts. We noted if and how any key differences in characteristics (such as stakeholder or system type) translated into any salient aspects of this multiperspective narrative but acknowledge that a reporting focusing on these differences might also be of interest.

Conclusions

The adoption of ePrescribing/CPOE in hospitals can be understood as cultural shifts that reframe the medication-related aspects of quality and safety, featuring coexisting benefits and problems. Implementing organisations and teams should consider the breadth and depth of changes that ePrescribing/CPOE adoption can trigger rather than focus on discrete benefits/problems and favour implementation strategies that: consider the preimplementation context; are responsive to (and transparent about) organisational and stakeholder needs and agendas; and can be sustained effectively over time as implementations develop and gradually transition to routine use and system optimisation. Alongside this, patients’ views and experiences should be sought throughout to ensure sustained patient satisfaction during system implementation and avoid unintended negative consequences on the organisations’ ability to enact patient-centred care.
