Policy PointsThe implementation of large‐scale health care interventions relies on a shared vision, commitment to change, coordination across sites, and a spanning of siloed knowledge.Enablers of the system should include building an authorizing environment; providing relevant, meaningful, transparent, and timely data; designating and distributing leadership and decision making; and fostering the emergence of a learning culture.Attention to these four enablers can set up a positive feedback loop to foster positive change that can protect against the loss of key staff, the presence of lone disruptors, and the enervating effects of uncertainty. Context: Large‐scale transformative initiatives have the potential to improve the quality, efficiency, and safety of health care. However, change is expensive, complex, and difficult to implement and sustain. This paper advances system enablers, which will help to guide large‐scale transformation in health care systems. Methods: A realist study of the implementation of a value‐based health care program between 2017 and 2021 was undertaken in every public hospital (n = 221) in New South Wales (NSW), Australia. Four data sources were used to elucidate initial program theories beginning with a set of literature reviews, a program document review, and informal discussions with key stakeholders. Semistructured interviews were then conducted with 56 stakeholders to confirm, refute, or refine the theories. A retroductive analysis produced a series of context‐mechanism‐outcome (CMO) statements. Next, the CMOs were validated with three health care quality expert panels (n = 51). Synthesized data were interrogated to distill the overarching system enablers. Findings: Forty‐two CMO statements from the eight initial program theory areas were developed, refined, and validated. Four system enablers were identified: (1) build an authorizing environment; (2) provide relevant, authentic, timely, and meaningful data; (3) designate and distribute leadership and decision making; and (4) support the emergence of a learning culture. The system enablers provide a nuanced understanding of large‐system transformation that illustrates when, for whom, and in what circumstances large‐system transformation worked well or worked poorly. Conclusions: System enablers offer nuanced guidance for the implementation of large‐scale health care interventions. The four enablers may be portable to similar contexts and provide the empirical basis for an implementation model of large‐system value‐based health care initiatives. With concerted application, these findings can pave the way not just for a better understanding of greater or lesser success in intervening in health care settings but ultimately to contribute higher quality, higher value, and safer care.

Canadians have expressed concern that access to a family physician (FP) has declined precipitously. Yet FP to population ratios remained relatively stable over the last decade, and there were perceptions of physician surpluses, at least in urban centres, 10 years ago. We evaluated whether demographic changes among patients and FPs, and in the volume of care received and provided over the period, contribute to this paradox. Given the relationship between age and FP use in fiscal year 1991/1992, an aging population should have been associated with a 2 per cent increase in visits by 2000/2001. Likewise, given the relationship between FP age and workloads in 1991/1992, an aging workforce should have been associated with a 12 per cent increase in service provision a decade later. Yet visit rates and average FP workloads remained unchanged. There was an increase in age-specific rates of FP use among older adults and a decline in rates among the young, and an increase in age-specific workloads such that older FPs provided many more services than their predecessors (30%) and younger FPs provided many fewer (20%). In terms of impact on future requirements for FPs, both changes in age-specific rates of use, and changes in age-specific patterns of FP productivity, trump population aging as key drivers.

Canadians have expressed concern that access to family physicians (FP) has declined. Anonymized physician services data for 1991/1992 to 2000/2001 were used to evaluate changes in supply and age-specific rates of use of FPs and specialists in Winnipeg, Manitoba. Physician-to-population ratios declined 7.5 per cent, FP-to-population ratios declined 4.8 per cent, and specialist-to-population ratios declined 10.0 per cent. Among the general population, FP visit rates declined 3 per cent. Among older adults, physician visit rates increased 2.3 per cent, FP visit rates increased 10.9 per cent, and specialist visit rates declined 15.7 per cent. By comparison, we document declines in FP use by those younger than 5 years (25.5%) and those 6 to 19 years of age (18.6%). Increases in FP and declines in specialist use occurred primarily among those aged 65 to 84 years. By 2000/2001 older adults accounted for 25 per cent of all FP encounters. Gains in FP use among older adults was less attributable to the presence of more seniors and more related to the fact that a higher proportion of them are visiting a FP each year and, potentially, substituting primary for secondary care.

Objectives: To investigate the nature and potential implications of under-reporting of morbidity information in administrative hospital data. Setting and participants: Retrospective analysis of linked self-report and administrative hospital data for 32 832 participants in the large-scale cohort study (45 and Up Study), who joined the study from 2006 to 2009 and who were admitted to 313 hospitals in New South Wales, Australia, for at least an overnight stay, up to a year prior to study entry. Outcome measures: Agreement between self-report and recording of six morbidities in administrative hospital data, and between-hospital variation and predictors of positive agreement between the two data sources. Results: Agreement between data sources was good for diabetes (κ=0.79); moderate for smoking (κ=0.59); fair for heart disease, stroke and hypertension (κ=0.40, κ=0.30 and κ =0.24, respectively); and poor for obesity (κ=0.09), indicating that a large number of individuals with self-reported morbidities did not have a corresponding diagnosis coded in their hospital records. Significant between-hospital variation was found (ranging from 8% of unexplained variation for diabetes to 22% for heart disease), with higher agreement in public and large hospitals, and hospitals with greater depth of coding. Conclusions: The recording of six common health conditions in administrative hospital data is highly variable, and for some conditions, very poor. To support more valid performance comparisons, it is important to stratify or control for factors that predict the completeness of recording, including hospital depth of coding and hospital type (public/private), and to increase efforts to standardise recording across hospitals. Studies using these conditions for risk adjustment should also be cautious of their use in smaller hospitals. [ABSTRACT FROM AUTHOR]

Objective: To examine 9-year rates of family physician (FP) and psychiatrist use, as well as patterns of mental health services delivery by FPs. Method: We used population-based data from Winnipeg, Manitoba, to construct mutually exclusive cohorts of adults treated for major or minor mental health disorders in fiscal years 1992-1993 to 2000-2001. For each year, we measured patterns of use in this population and patterns of mental health practice among FPs. Results: The treatment prevalence rate was 224 per 1000 in 2000-2001 and 174 per 1000 in 1992-1993, and the rates for major and minor mental health disorders increased over the 9-year period by 15% and 31%. respectively. In 2000-2001. 92% of adults treated for mental illness saw at least one FP, and 45% saw an FP but no psychiatrist. Adults with major or minor mental health disorders visited an FP on average 9.1 and 6.9 times yearly, respectively, and FP visit rates remained relatively stable. There was a gradient in use by socioeconomic status: adults from communities with lower socioeconomic status had the highest rates of use. By 2000-2001, 24% of FPs billed for services related to psychosocial conditions as often as they did for the most frequent conditions seen in primary care. Conclusion: Between 1992-1993 and 2000-2001, the study population's patterns of FP and psychiatrist use remained relatively stable. In more recent years, FPs provided more mental health services than in previous years; this related to increased treatment prevalence rather than to increases in use per adult. FPs played a major role in the provision of mental health care. [ABSTRACT FROM AUTHOR]
