Developing a set of emergency department performance measures to evaluate delirium care quality for older adults: a modified e-Delphi study.

BACKGROUND: Older adults are at high risk of developing delirium in the emergency department (ED); however, it is under-recognized in routine clinical care. Lack of detection and treatment is associated with poor outcomes, such as mortality. Performance measures (PMs) are needed to identify variations in quality care to help guide improvement strategies. The purpose of this study is to gain consensus on a set of quality statements and PMs that can be used to evaluate delirium care quality for older ED patients. METHODS: A 3-round modified e-Delphi study was conducted with ED clinical experts. In each round, participants rated quality statements according to the concepts of importance and actionability, then their associated PMs according to the concept of necessity (1-9 Likert scales), with the ability to comment on each. Consensus and stability were evaluated using a priori criteria using descriptive statistics. Qualitative data was examined to identify themes within and across quality statements and PMs, which went through a participant validation exercise in the final round. RESULTS: Twenty-two experts participated, 95.5% were from west or central Canada. From 10 quality statements and 24 PMs, consensus was achieved for six quality statements and 22 PMs. Qualitative data supported justification for including three quality statements and one PM that achieved consensus slightly below a priori criteria. Three overarching themes emerged from the qualitative data related to quality statement actionability. Nine quality statements, nine structure PMs, and 14 process PMs are included in the final set, addressing four areas of delirium care: screening, diagnosis, risk reduction and management. CONCLUSION: Results provide a set of quality statements and PMs that are important, actionable, and necessary to a diverse group of clinical experts. To our knowledge, this is the first known study to develop a de novo set of guideline-based quality statements and PMs to evaluate the quality of delirium care older adults receive in the ED setting.

Lifting the curtain on the emergency department crisis: a multi-method reception study of Larry Saves the Canadian Healthcare System.

BACKGROUND: Despite growing evidence of the potential of arts-based modalities to translate knowledge and spark discussion on complex issues, applications to health policy are rare. This study explored the potential of a research-based theatrical video to increase public capacity and motivation to engage with the complex issues that make Emergency Department wait times such an intractable problem. METHODS: Larry Saves the Canadian Healthcare System is a digital musical micro-series developed from extensive research examining system-level causes of Emergency crowding and the ineffectiveness of prevailing approaches. We released individual episodes and a revised full-length version on YouTube, using organic promotion strategies and paid advertising. We used YouTube Analytics to track views, engagement and viewer demographics, and content-analyzed viewer comments. We also conducted five university-based screenings; 92 students completed questionnaires, rating Larry on 16 descriptors using a 7-point Likert scale. RESULTS: From June 2022 through May 2023, Larry garnered over 100,000 views (76,752 of the full-length version, 35,535 of episodes), 1329 likes, 2780 shares, and 139 comments. Views and watch time were higher among women and positively associated with age. Among YouTube comments, the predominating themes were praise for the video and criticism of the healthcare system. Many commenters applauded the show's accuracy, humor, and/or resonance with their experience; several shared healthcare horror stories. Students overwhelmingly agreed with all positive and disagreed with all negative descriptors, and nearly unanimously deemed the video informative, thought-provoking, and entertaining. Most also affirmed that it had increased their knowledge, interest, and confidence to participate in discussions about healthcare issues. Neither gender, primary language, nor employment in healthcare predicted ratings, but graduate students and those 25+ years old evaluated the video most positively. DISCUSSION: These findings highlight the promise of research-informed musical satire to inform and invigorate discourse on an urgent health policy problem. Larry has reached tens of thousands of viewers, garnered excellent feedback, and received high student ratings. Further research should directly assess educational and behavioural outcomes and explore what facilitative strategies could maximize this knowledge translation product's potential to foster informed, impactful policy dialogue.

A critical appraisal and recommendation synthesis of delirium clinical practice guidelines relevant to the care of older adults in the emergency department: An umbrella review.

RATIONALE: Older adults are at high risk of developing delirium in the emergency department (ED); however, it is often missed or undertreated. Improving ED delirium care is challenging in part due to a lack of standards to guide best practice. Clinical practice guidelines (CPGs) translate evidence into recommendations to improve practice. AIM: To critically appraise and synthesize CPG recommendations for delirium care relevant to older ED patients. METHODS: We conducted an umbrella review to retrieve relevant CPGs. Quality of the CPGs and their recommendations were critically appraised using the Appraisal of Guidelines, Research, and Evaluation (AGREE)-II; and Appraisal of Guidelines Research and Evaluation-Recommendations Excellence (AGREE-REX) instruments. A threshold of 70% or greater in the AGREE-II Rigour of Development domain was used to define high-quality CPGs. Delirium recommendations from CPGs meeting this threshold were included in the synthesis and narrative analysis. RESULTS: AGREE-II Rigour of Development scores ranged from 37% to 83%, with 5 of 10 CPGs meeting the predefined threshold. AGREE-REX overall calculated scores ranged from 44% to 80%. Recommendations were grouped into screening, diagnosis, risk reduction, and management. Although none of the included CPGs were ED-specific, many recommendations incorporated evidence from this setting. There was agreement that screening for nonmodifiable risk factors is important to define high-risk populations, and those at risk should be screened for delirium. The '4A's Test' was the recommended tool to use in the ED specifically. Multicomponent strategies were recommended for delirium risk reduction, and for its management if it occurs. The only area of disagreement was for the short-term use of antipsychotic medication in urgent situations. CONCLUSION: This is the first known review of delirium CPGs including a critical appraisal and synthesis of recommendations. Researchers and policymakers can use this synthesis to inform future improvement efforts and research in the ED.

A critical appraisal of delirium clinical practice guidelines relevant to the care of older adults in the emergency department with a synthesis of recommendations: an umbrella review protocol.

BACKGROUND: Up to 35% of older adults present to the emergency department (ED) with delirium or develop the condition during their ED stay. Delirium associated with an ED visit is independently linked to poorer outcomes such as loss of independence, increased length of hospital stay, and mortality. Improving the quality of delirium care for older ED patients is hindered by a lack of knowledge and standards to guide best practice. High-quality clinical practice guidelines (CPGs) have the power to translate the complexity of scientific evidence into recommendations to improve and standardize practice. This study will identify and synthesize recommendations from high-quality delirium CPGs relevant to the care of older ED patients. METHODS: We will conduct a multi-phase umbrella review to retrieve relevant CPGs. Quality of the CPGs and their recommendations will be critically appraised using the Appraisal of Guidelines, Research, and Evaluation (AGREE)-II; and Appraisal of Guidelines Research and Evaluation - Recommendations Excellence (AGREE-REX) instruments, respectively. We will also synthesize and conduct a narrative analysis of high-quality CPG recommendations. DISCUSSION: This review will be the first known evidence synthesis of delirium CPGs including a critical appraisal and synthesis of recommendations. Recommendations will be categorized according to target population and setting as a means to define the bredth of knowledge in this area. Future research will use consensus building methods to identify which are most relevant to older ED patients. TRIAL REGISTRATION: This study has been registered in the Open Science Framework registries: https://doi.org/10.17605/OSF.IO/TG7S6 .

Managing intergroup silos to improve patient flow.

BACKGROUND: Health care managers face the critical challenge of overcoming divisions among the many groups involved in patient care, a problem intensified when patients must flow across multiple settings. Surprisingly, however, the patient flow literature rarely engages with its intergroup dimension. PURPOSE: This study explored how managers with responsibility for patient flow understand and approach intergroup divisions and "silo-ing" in health care. METHODOLOGY/APPROACH: We conducted in-depth interviews with 300 purposively sampled senior, middle, and frontline managers across 10 Canadian health jurisdictions. We undertook thematic analysis using sensitizing concepts drawn from the social identity approach. RESULTS: Silos, at multiple levels, were reported in every jurisdiction. The main strategies for ameliorating silos were provision of formal opportunities for staff collaboration, persuasive messages stressing shared values or responsibilities, and structural reorganization to redraw group boundaries. Participants emphasized the benefits of the first two but described structural change as neither necessary nor sufficient for improved collaboration. CONCLUSION: Silos, though an unavoidable feature of organizational life, can be managed and mitigated. However, a key challenge in redefining groups is that the easiest place to draw boundaries from a social identity perspective may not be the best place from one of system design. Narrowly defined groups forge strong identities more easily, but broader groups facilitate coordination of care by minimizing the number of boundaries patients must traverse. PRACTICE IMPLICATIONS: A thoughtfully designed combination of strategies may help to improve intergroup relations and their impact on flow. It may be ideal to foster a "mosaic" identity that affirms group allegiances at multiple levels.

The "hard, relentless, never-ending" work of focusing on discharge: a qualitative study of managers' perspectives.

PURPOSE: Interventions to hasten patient discharge continue to proliferate despite evidence that they may be achieving diminishing returns. To better understand what such interventions can be expected to accomplish, the authors aim to critically examine their underlying program theory. DESIGN/METHODOLOGY/APPROACH: Within a broader study on patient flow, spanning 10 jurisdictions across Western Canada, the authors conducted in-depth interviews with 300 senior, middle and frontline managers; 174 discussed discharge initiatives. Using thematic analysis informed by a Realistic Evaluation lens, the authors identified the mechanisms by which discharge activities were believed to produce their impacts and the strategies and context factors necessary to trigger the intended mechanisms. FINDINGS: Managers' accounts suggested a common program theory that applied to a wide variety of discharge initiatives. The chief mechanism was inculcation of a sharp focus on discharge; reinforcing mechanisms included development of shared understanding and a sense of accountability. Participants reported that these mechanisms were difficult to produce and sustain, requiring continual active management and repeated (re)introduction of interventions. This reflected a context in which providers, already overwhelmed with competing demands, were unlikely to be able (or perhaps even willing) to sustain a focus on this particular aspect of care. ORIGINALITY/VALUE: The finding that "discharge focus" emerged as the core mechanism of discharge interventions helps to explain why such initiatives may be achieving limited benefit. There is a need for interventions that promote timely discharge without relying on this highly problematic mechanism.

Designing centralized waiting lists for attachment to a primary care provider: Considerations from a logic analysis.

Access to a regular primary care provider is essential to quality care. In Canada, where 15 % of patients are unattached (i.e., without a regular provider), centralized waiting lists (CWLs) help attach patients to a primary care provider (family physician or nurse practitioner). Previous studies reveal mechanisms needed for CWLs to work, but focus mostly on CWLs for specialized health care. We aim to better understand how to design CWLs for unattached patients in primary care. In this study, a logic analysis compares empirical evidence from a qualitative case study of CWLs for unattached patients in seven Canadian provinces to programme theory derived from a realist review on CWLs. Data is analyzed using context-intervention-mechanism-outcome configurations. Results identify mechanisms involved in three components of CWL design: patient registration, patient prioritization, and patient assignment to a provider for attachment. CWL programme theory is revised to integrate mechanisms specific to primary care, where patients, rather than referring providers, are responsible for registering on the CWL, where prioritization must consider a broad range of conditions and characteristics, and where long-term acceptability of attachment is important. The study provides new insight into mechanisms that enable CWLs for unattached patients to work.

Despite Interventions, Emergency Flow Stagnates in Urban Western Canada.

Purpose: This paper reports the quantitative component of a mixed-methods study of patient flow in the 10 urban health regions/zones of Western Canada. We assessed whether jurisdictions differed meaningfully in their emergency flow performance, defined as mean emergency department length of stay (ED LOS). Methods: We used hierarchical linear modelling to compare ED LOS across jurisdictions, based on nationally reported data for 2017 to 2018. We also explored 36-month performance trends. Admitted and discharged patients were analyzed separately. Results: With the exception of one high performer, no region's performance differed significantly from average for both admitted and discharged patients. The regions' levels of performance remained largely static throughout the study period. Conclusions: Results precluded any mixed-methods comparison of high- and low-performing regions. However, they converged with our qualitative findings, which suggested that most regions were pursuing similar flow-improvement strategies with limited effectiveness. Deeper changes may be required to address persistent misalignment between capacity and demand.

Can facility-based transitional care improve patient flow? Lessons from four Canadian regions.

Units providing transitional, subacute, or restorative care represent a common intervention to facilitate patient flow and improve outcomes for lower acuity (often older) inpatients; however, little is known about Canadian health systems' experiences with such "transition units." This comparative case study of diverse units in four health regions (48 interviews) identified important success factors and pitfalls. A fundamental requirement for success is to clearly define the unit's intended population and design the model around its needs. Planners must also ensure that the unit be resourced and staffed to deliver truly restorative care. Finally, streamlined processes must be developed to help patients access and move through the unit. Units that were perceived as more effective appeared to have satisfactorily addressed these population, capacity, and process issues, whereas those perceived as less effective continued to struggle with them. Findings suggest principles to support optimal design and implementation of transition units.

Conceptualizing the Organization of Surgical Services Comment on "Decentralization and Regionalization of Surgical Care: A Review of Evidence for the Optimal Distribution of Surgical Services in Low- and Middle-Income Countries".

According to Iverson and colleagues' thoughtful analysis, decisions to decentralize or regionalize surgical services must take into account contextual realities that may impede the safe execution of certain delivery models in low-and middle-income countries (LMICs), and should be governed by procedure-related considerations (specifically, volume, patient acuity, and procedure complexity). This commentary suggests that, by shifting attention to the mechanisms whereby (de)centralization may exert beneficial impacts, it is possible to generate guidance applicable to countries across the socioeconomic spectrum. Four key mechanisms can be identified: decentralization (1) minimizes the need for patients to travel for care and, (2) obviates certain system-induced delays once patients present; centralization (3) facilitates the maintenance of a workforce with sufficient expertise to offer services safely, and (4) conserves resources by limiting the number of sites. The commentary elucidates how context- and procedure-related factors determine the importance of each mechanism, allowing planners to prioritize among them. Although some context factors have special relevance to LMICs, most can also appear in high-income countries (HICs), and the procedure-related factors are universal. Thus, evidence from countries at all income levels might be fruitfully combined into an integrated body of context-sensitive guidance.

When Coproduction Is Unproductive Comment on "Experience of Health Leadership in Partnering with University-Based Researchers in Canada: A Call to 'Re-Imagine' Research".

Bowen et al offer a sobering look at the reality of research partnerships from the decision-maker perspective. Health leaders who had actively engaged in such partnerships continued to describe research as irrelevant and unhelpful - just the problem that partnered research was intended to solve. This commentary further examines the many barriers that impede researchers from meeting decision-makers' knowledge needs, and decision-makers from using knowledge that they have coproduced. It argues that not all barriers can or should be dismantled: some are legitimate and beneficial; some are harmful but deeply entrenched; some arise unpredictably. This being the case, it seems unrealistic to expect either existing or emerging strategies to create a macro-context devoid of barriers to the fruitful coproduction of knowledge. However, it may be possible to identify and support micro-contexts (configurations of participants, settings, and project characteristics) in which partnered research is most likely to achieve its aims.

How the design and implementation of centralized waiting lists influence their use and effect on access to healthcare - A realist review.

CONTEXT: Many health systems have centralized waiting lists (CWLs), but there is limited evidence on CWL effectiveness and how to design and implement them. AIM: To understand how CWLs' design and implementation influence their use and effect on access to healthcare. METHODS: We conducted a realist review (n = 21 articles), extracting context-intervention-mechanism-outcome configurations to identify demi-regularities (i.e., recurring patterns of how CWLs work). RESULTS: In implementing non-mandatory CWLs, acceptability to providers influences their uptake of the CWL. CWL eligibility criteria that are unclear or conflict with providers' role or judgement may result in inequities in patient registration. In CWLs that prioritize patients, providers must perceive the criteria as clear and appropriate to assess patients' level of need; otherwise, prioritization may be inconsistent. During patients' assignment to service providers, providers may select less-complex patients to obtain CWLs rewards or avoid penalties; or may select patients for other policies with stronger incentives, disregarding the established patient order and leading to inequities and limited effectiveness. CONCLUSION: These findings highlight the need to consider provider behaviours in the four sequential CWL design components: CWL implementation, patient registration, patient prioritization and patient assignment to providers. Otherwise, CWLs may result in limited effects on access or lead to inequities in access to services.

"Working Against Gravity": The Uphill Task of Overcapacity Management.

While most health systems have implemented interventions to manage situations in which patient demand exceeds capacity, little is known about the long-term sustainability or effectiveness of such interventions. A large multi-jurisdictional study on patient flow in Western Canada provided the opportunity to explore experiences with overcapacity management strategies across 10 diverse health regions. Four categories of interventions were employed by all or most regions: overcapacity protocols, alternative locations for emergency patients, locations for discharge-ready inpatients, and meetings to guide redistribution of patients. Two mechanisms undergirded successful interventions: providing a capacity buffer and promoting action by inpatient units by increasing staff accountability and/or solidarity. Participants reported that interventions demanded significant time and resources and the ongoing active involvement of middle and senior management. Furthermore, although most participants characterized overcapacity management practices as effective, this effectiveness was almost universally experienced as temporary. Many regions described a context of chronic overcapacity, which persisted despite continued intervention. Processes designed to manage short-term surges in demand cannot rectify a long-term mismatch between capacity and demand; solutions at the level of system redesign are needed.

The stipulation-stimulation spiral: A model of system change.

This paper proposes a general model, based on what is known about the nature of (complex) systems, of how systems-in particular, health care systems-respond to attempted change. Inferences are drawn from a critical literature review and reinterpretation of two primary studies. The two fundamental system-change approaches are "stipulation" and "stimulation": stip(ulation) attempts to elicit a specific response from the system; stim(ulation) encourages the system to generate diverse responses. Each has a unique strength: stip's is precision, the ability to directly impact the desired outcome and only that outcome; stim's is resonance, the ability to take advantage of behavior already present within the system. Each approach's inherent strength is its complement's inherent weakness; thus, stip and stim often clash if attempted simultaneously but can reinforce each other if applied in alternation. Opposite patterns (the "stip-stim spiral" vs "stip-stim stalemate") are observed to underpin successful vs failed system change: The crucial difference is whether decision-makers respond to a need for precision/resonance by strengthening the appropriate approach (stipulation/stimulation, respectively), or merely by weakening its complement. With further validation, the model has the potential to yield a more fundamental understanding of why system-change efforts fail and how they can succeed.

Pushing for partnership: physician engagement and resistance in primary care renewal.

PURPOSE: Healthcare policymakers and managers struggle to engage private physicians, who tend to view themselves as independent of the system, in new models of primary care. The purpose of this paper is to examine this issue through a social identity lens. DESIGN/METHODOLOGY/APPROACH: Through in-depth interviews with 33 decision-makers and 31 fee-for-service family physicians, supplemented by document review and participant observation, the authors studied a Canadian province's early efforts to engage physicians in primary care renewal initiatives. FINDINGS: Recognizing that the existing physician-system relationship was generally distant, decision-makers invested effort in relationship-building. However, decision-makers' rhetoric, as well as the design of their flagship initiative, evinced an attempt to proceed directly from interpersonal relationship-building to the establishment of formal intergroup partnership, with no intervening phase of supporting physicians' group identity and empowering them to assume equal partnership. The invitation to partnership did not resonate with most physicians: many viewed it as an inauthentic offer from an out-group ("bureaucrats") with discordant values; others interpreted partnership as a mere transactional exchange. Such perceptions posed barriers to physician participation in renewal activities. PRACTICAL IMPLICATIONS: The pursuit of a premature degree of intergroup closeness can be counterproductive, heightening physician resistance. ORIGINALITY/VALUE: This study revealed that even a relatively subtle misalignment between a particular social identity management strategy and its intergroup context can have highly problematic ramifications. Findings advance the literature on social identity management and may facilitate the development of more effective engagement strategies.

Primary care reform in Manitoba, Canada, 2011-15: Balancing accountability and acceptability.

Primary care reform cannot succeed without substantive change on the part of providers. In Canada, these are mostly fee-for-service physicians, who tend to regard themselves as independent professionals and not under managerial sway. Hence, policymakers must balance two conflicting imperatives: ensuring the acceptability of renewal efforts to these physicians while enforcing their accountability for defined actions or outcomes. In its 2011-15 strategy to improve access to primary care, the province of Manitoba introduced several linked initiatives, each striving to blend acceptability- and accountability-promoting elements. Clearly delimited initiatives that directly promoted a specific observable behaviour (accountability) through financial or non-financial support (acceptability) were most successfully implemented. System-wide initiatives with complicated designs (notably a primary care network model that established formal partnership among clinics and regional health authorities) encountered greater difficulties in recruiting and sustaining physician participation. Although such initiatives offered physicians considerable decision-making latitude (acceptability), many physicians questioned the meaningfulness of opportunities for voice within a predetermined structure (accountability). Moreover, policymakers struggled to enhance the acceptability of such initiatives without sacrificing strong accountability mechanisms. Policymakers must carefully consider how acceptability and accountability elements may interact, and design them in such a way as to minimize the risk of mutual interference.

Advancing the evaluation of integrated knowledge translation.

BACKGROUND: Integrated knowledge translation (IKT) flows from the premise that knowledge co-produced with decision-makers is more likely to inform subsequent decisions. However, evaluations of manager/policy-maker-focused IKT often concentrate on intermediate outcomes, stopping short of assessing whether research findings have contributed to identifiable organisational action. Such hesitancy may reflect the difficulty of tracing the causes of this distal, multifactorial outcome. This paper elucidates how an approach based on realistic evaluation could advance the field. MAIN TEXT: Realistic evaluation views outcomes as a joint product of intervention mechanisms and context. Through identification of context-mechanism-outcome configurations, it enables the systematic testing and refinement of 'mid-range theory' applicable to diverse interventions that share a similar underlying logic of action. The 'context-sensitive causal chain' diagram, a tool adapted from the broader theory-based evaluation literature, offers a useful means of visualising the posited chain from activities to outcomes via mechanisms, and the context factors that facilitate or disrupt each linkage (e.g. activity-mechanism, mechanism-outcome). Drawing on relevant literature, this paper proposes a context-sensitive causal chain by which IKT may generate instrumental use of research findings (i.e. direct use to make a concrete decision) and identifies an existing tool to assess this outcome, then adapts the chain to describe a more subtle, indirect pathway of influence. Key mechanisms include capacity- and relationship-building among researchers and decision-makers, changes in the (perceived) credibility and usability of findings, changes in decision-makers' beliefs and attitudes, and incorporation of new knowledge in an actual decision. Project-specific context factors may impinge upon each linkage; equally important is the organisation's absorptive capacity, namely its overall ability to acquire, assimilate and apply knowledge. Given a sufficiently poor decision-making environment, even well-implemented IKT that triggers important mechanisms may fall short of its desired outcomes. Further research may identify additional mechanisms and context factors. CONCLUSION: By investigating 'what it is about an intervention that works, for whom, under what conditions', realistic evaluation addresses questions of causality head-on without sacrificing complexity. A realist approach could contribute greatly to our ability to assess - and, ultimately, to increase - the value of IKT.

Planning without action and action without planning? Examining a regional health system's efforts to improve patient flow, 1998-2013.

Most health care organizations engage in formal and informal planning, yet their improvement initiatives may remain disjointed and reactive. Research on organizational decision-making has found that the "discovery" approach (seek and assess multiple options before selecting one) outperforms "idea imposition" (identify 1 option, then gather information to [dis]confirm it), yet is observed relatively infrequently. Might this imply that discovery frequently collapses before fruition? This qualitative study sought to better understand the planning-action disjunction, as observed in 1 organization, by comparing its planning processes against the discovery approach. It focused on a Canadian regional health system's recurrent, unsuccessful attempts to improve patient flow. Through extensive document review supplemented by interviews with 62 managers, it identified all relevant regional plans/reports produced during a 15-year period and followed each recommendation forward in time to discover its fate. Each report presented a lengthy, unprioritized list of disparate recommendations, few of which progressed to full implementation. It appeared that decision-makers repeatedly embarked on a discovery approach, but rapidly allowed it to splinter into multiple idea-imposition approaches; numerous options were generated, but never evaluated against each other. Thus, the product of each planning process was not a coherent strategy but a list of disconnected actions.

Regional consolidation of orthopedic surgery: impacts on hip fracture surgery access and outcomes.

BACKGROUND: Timely access to orthopedic trauma surgery is essential for optimal outcomes. Regionalization of some types of surgery has shown positive effects on access, timeliness and outcomes. We investigated how the consolidation of orthopedic surgery in 1 Canadian health region affected patients requiring hip fracture surgery. METHODS: We retrieved administrative data on all regional emergency department visits for lower-extremity injury and all linked inpatient stays from January 2010 through March 2013, identifying 1885 hip-fracture surgeries. Statistical process control and interrupted time series analysis controlling for demographics and comorbidities were used to assess impacts on access (receipt of surgery within 48-h benchmark) and surgical outcomes (complications, in-hospital/30-d mortality, length of stay). RESULTS: There was a significant increase in the proportion of patients receiving surgery within the benchmark. Complication rates did not change, but there appeared to be some decrease in mortality (significant at 6 mo). Length of stay increased at a hospital that experienced a major increase in patient volume, perhaps reflecting challenges associated with patient flow. CONCLUSION: Regionalization appeared to improve the timeliness of surgery and may have reduced mortality. The specific features of the present consolidation (including pre-existing interhospital performance variation and the introduction of daytime slates at the referral hospital) should be considered when interpreting the findings.

CONTEXTE: En traumatologie, l'accès rapide à la chirurgie orthopédique est essentiel pour l'obtention de résultats optimaux. La régionalisation de certains types de chirurgie a eu des effets positifs sur l'accès aux soins, leur rapidité et leurs résultats. Nous avons vérifié l'effet qu'a eu la consolidation des soins chirurgicaux orthopédiques dans une région sanitaire canadienne sur les patients qui ont eu recours à la chirurgie pour une fracture de la hanche. MÉTHODES: Nous avons obtenu les données administratives concernant toutes les consultations dans les services d'urgence régionaux pour des blessures aux membres inférieurs et nous les avons corrélées avec les séjours hospitaliers de janvier 2010 à mars 2013. Nous avons ainsi recensé 1885 chirurgies pour fracture de la hanche. Nous avons utilisé la maîtrise statistique des procédés et le modèle chronologique interrompu et nous avons tenu compte des caractéristiques démographiques et des comorbidités pour évaluer les impacts sur l'accès aux interventions (attente limite de 48 h pour obtenir la chirurgie) et leurs résultats (complications, mortalité perhospitalière à 30 j et durée des séjours). RÉSULTATS: On a noté une augmentation significative de la proportion de patients traités par chirurgie à l'intérieur des délais. Les taux de complications n'ont pas varié, mais il semble y avoir eu une certaine diminution de la mortalité (significative à 6 mois). La durée des séjours a augmenté dans un hôpital qui a connu un accroissement majeur de sa clientèle, témoignant peut-être de difficultés liées à l'afflux de patients. CONCLUSION: La régionalisation a semblé améliorer l'accès rapide à la chirurgie et pourrait avoir réduit la mortalité. Il faut tenir compte des caractéristiques spécifiques de la présente consolidation (y compris la variation préexistante du rendement interhospitalier et la création de listes de jour à l'hôpital de référence) avant d'interpréter ces conclusions.

The three paradoxes of patient flow: an explanatory case study.

BACKGROUND: Health systems in many jurisdictions struggle to reduce Emergency Department congestion and improve patient flow across the continuum of care. Flow is often described as a systemic issue requiring a "system approach"; however, the implications of this idea remain poorly understood. Focusing on a Canadian regional health system whose flow problems have been particularly intractable, this study sought to determine what system-level flaws impede healthcare organizations from improving flow. METHODS: This study drew primarily on qualitative data from in-depth interviews with 62 senior, middle and departmental managers representing the Region, its programs and sites; quantitative analysis of key flow indicators (1999-2012) and review of ~700 documents furnished important context. Examination of the interview data revealed that the most striking feature of the dataset was contradiction; accordingly, a technique of dialectical analysis was developed to examine observed contradictions at successively deeper levels. RESULTS: Analysis uncovered three paradoxes: "Many Small Successes and One Big Failure" (initiatives improve parts of the system but fail to fix underlying system constraints); "Your Innovation Is My Aggravation" (local innovation clashes with regional integration); and most critically, "Your Order Is My Chaos" (rules that improve service organization for my patients create obstacles for yours). This last emerges when some entities (sites/hospitals) define their patients in terms of their location in the system, while others (regional programs) define them in terms of their needs/characteristics. As accountability for improving flow was distributed among groups that thus variously defined their patients, local efforts achieved little for the overall system, and often clashed with each other. These paradoxes are indicative of a fundamental antagonism between the system's parts and the whole. CONCLUSION: An accretion of flow initiatives in all parts of the system will never add up to a system approach, and may indeed perpetuate the paradoxes. What is needed is a coherent strategy of defining patient populations by needs, analyzing their entire trajectories of care, and developing consistent processes to better meet those needs.
