Nurturing an organizational context that supports team-based primary mental health care: A grounded theory study.

BACKGROUND: The expansion of the Patient-Centred Medical Home model presents a valuable opportunity to enhance the integration of team-based mental health services in primary care settings, thereby meeting the growing demand for such services. Understanding the organizational context of a Patient-Centred Medical Home is crucial for identifying the facilitators and barriers to integrating mental health care within primary care. The main objective of this paper is to present the findings related to the following research question: "What organizational features shape Family Health Teams' capacity to provide mental health services for depression and anxiety across Ontario, Canada?" METHODS: Adopting a constructivist grounded theory approach, we conducted interviews with various mental health care providers, and administrators within Ontario's Family Health Teams, in addition to engaging provincial policy informants and community stakeholders. Data analysis involved a team-based approach, including code comparison and labelling, with a dedicated data analysis subcommittee convening monthly to explore coded concepts influencing contextual factors. RESULTS: From the 96 interviews conducted, involving 82 participants, key insights emerged on the organizational contextual features considered vital in facilitating team-based mental health care in primary care settings. Five prominent themes were identified: i) mental health explicit in the organizational vision, ii) leadership driving mental health care, iii) developing a mature and stable team, iv) adequate physical space that facilitates team interaction, and v) electronic medical records to facilitate team communication. CONCLUSIONS: This study underscores the often-neglected organizational elements that influence primary care teams' capacity to deliver quality mental health care services. It highlights the significance of strong leadership complemented by effective communication and collaboration within teams to enhance their ability to provide mental health care. Strengthening relationships within primary care teams lies at the core of effective healthcare delivery and should be leveraged to improve the integration of mental health care.

Inequities in the delivery of mental health care: a grounded theory study of the policy context of primary care.

BACKGROUND: Strengthening capacity for mental health in primary care improves health outcomes by providing timely access to coordinated and integrated mental health care. The successful integration of mental health in primary care is highly dependent on the foundation of the surrounding policy context. In Ontario, Canada, policy reforms in the early 2000's led to the implementation of a new interprofessional team-model of primary care called Family Health Teams. It is unclear the extent to which the policy context in Ontario influenced the integration of mental health care in Family Health Teams emerging from this period of policy reform. The research question guiding this study was: what were key features of Ontario's policy context that influenced FHTs capacity to provide mental health services for mood and anxiety disorders? METHODS: A qualitative study informed by constructivist grounded theory. Individual interviews were conducted with executive directors, family physicians, nurse practitioners, nurses, and the range of professionals who provide mental health services in interprofessional primary care teams; community mental health providers; and provincial policy and decision makers. We used an inductive approach to data analysis. The electronic data management programme NVivo11 helped organise the data analysis process. RESULTS: We conducted 96 interviews with 82 participants. With respect to the contextual factors considered to be important features of Ontario's policy context that influenced primary care teams' capacity to provide mental health services, we identified four key themes: i) lack of strategic direction for mental health, ii) inadequate resourcing for mental health care, iii) rivalry and envy, and, iv) variations across primary care models. CONCLUSIONS: As the first point of contact for individuals experiencing mental health difficulties, primary care plays an important role in addressing population mental health care needs. In Ontario, the successful integration of mental health in primary care has been hindered by the lack of strategic direction, and inconsistent resourcing for mental health care. Achieving health equity may be stunted by the structural variations for mental health care across Family Health Teams and across primary care models in Ontario.

Patient perspectives on quality of care for depression and anxiety in primary health care teams: A qualitative study.

BACKGROUND: Widespread policy reforms in Canada, the United States and elsewhere over the last two decades strengthened team models of primary care by bringing together family physicians and nurse practitioners with a range of mental health and other interdisciplinary providers. Understanding how patients with depression and anxiety experience newer team-based models of care delivery is essential to explore whether the intended impact of these reforms is achieved, identify gaps that remain and provide direction on strengthening the quality of mental health care. OBJECTIVE: The main study objective was to understand patients' perspectives on the quality of care that they received for anxiety and depression in primary care teams. METHODS: This was a qualitative study, informed by constructivist grounded theory. We conducted focus groups and individual interviews with primary care patients about their experiences with mental health care. Focus groups and individual interviews were recorded and transcribed verbatim. Grounded theory guided an inductive analysis of the data. RESULTS: Forty patients participated in the study: 31 participated in one of four focus groups, and nine completed an individual interview. Participants in our study described their experiences with mental health care across four themes: accessibility, technical care, trusting relationships and meeting diverse needs. CONCLUSION: Greater attention by policymakers is needed to strengthen integrated collaborative practices in primary care so that patients have similar access to mental health services across different primary care practices, and smoother continuity of care across sectors. The research team is comprised of individuals with lived experience of mental health who have participated in all aspects of the research process.

Systematic review and meta-analysis of cohort studies of long term outdoor nitrogen dioxide exposure and mortality.

OBJECTIVE: To determine whether long term exposure to outdoor nitrogen dioxide (NO2) is associated with all-cause or cause-specific mortality. METHODS: MEDLINE, Embase, CENTRAL, Global Health and Toxline databases were searched using terms developed by a librarian. Screening, data extraction and risk of bias assessment were completed independently by two reviewers. Conflicts were resolved through consensus and/or involvement of a third reviewer. Pooling of results across studies was conducted using random effects models, heterogeneity among included studies was assessed using Cochran's Q and I2 measures, and sources of heterogeneity were evaluated using meta-regression. Sensitivity of pooled estimates to individual studies was examined and publication bias was evaluated using Funnel plots, Begg's and Egger's tests, and trim and fill. RESULTS: Seventy-nine studies based on 47 cohorts, plus one set of pooled analyses of multiple European cohorts, met inclusion criteria. There was a consistently high degree of heterogeneity. After excluding studies with probably high or high risk of bias in the confounding domain (n = 12), pooled hazard ratios (HR) indicated that long term exposure to NO2 was significantly associated with mortality from all/ natural causes (pooled HR 1.047, 95% confidence interval (CI), 1.023-1.072 per 10 ppb), cardiovascular disease (pooled HR 1.058, 95%CI 1.026-1.091), lung cancer (pooled HR 1.083, 95%CI 1.041-1.126), respiratory disease (pooled HR 1.062, 95%CI1.035-1.089), and ischemic heart disease (pooled HR 1.111, 95%CI 1.079-1.144). Pooled estimates based on multi-pollutant models were consistently smaller than those from single pollutant models and mostly non-significant. CONCLUSIONS: For all causes of death other than cerebrovascular disease, the overall quality of the evidence is moderate, and the strength of evidence is limited, while for cerebrovascular disease, overall quality is low and strength of evidence is inadequate. Important uncertainties remain, including potential confounding by co-pollutants or other concomitant exposures, and limited supporting mechanistic evidence.

Systematic review and meta-analysis of case-crossover and time-series studies of short term outdoor nitrogen dioxide exposure and ischemic heart disease morbidity.

BACKGROUND: Nitrogen dioxide (NO2) is a pervasive urban pollutant originating primarily from vehicle emissions. Ischemic heart disease (IHD) is associated with a considerable public health burden worldwide, but whether NO2 exposure is causally related to IHD morbidity remains in question. Our objective was to determine whether short term exposure to outdoor NO2 is causally associated with IHD-related morbidity based on a synthesis of findings from case-crossover and time-series studies. METHODS: MEDLINE, Embase, CENTRAL, Global Health and Toxline databases were searched using terms developed by a librarian. Screening, data extraction and risk of bias assessment were completed independently by two reviewers. Conflicts between reviewers were resolved through consensus and/or involvement of a third reviewer. Pooling of results across studies was conducted using random effects models, heterogeneity among included studies was assessed using Cochran's Q and I2 measures, and sources of heterogeneity were evaluated using meta-regression. Sensitivity of pooled estimates to individual studies was examined using Leave One Out analysis and publication bias was evaluated using Funnel plots, Begg's and Egger's tests, and trim and fill. RESULTS: Thirty-eight case-crossover studies and 48 time-series studies were included in our analysis. NO2 was significantly associated with IHD morbidity (pooled odds ratio from case-crossover studies: 1.074 95% CI 1.052-1.097; pooled relative risk from time-series studies: 1.022 95% CI 1.016-1.029 per 10 ppb). Pooled estimates for case-crossover studies from Europe and North America were significantly lower than for studies conducted elsewhere. The high degree of heterogeneity among studies was only partially accounted for in meta-regression. There was evidence of publication bias, particularly for case-crossover studies. For both case-crossover and time-series studies, pooled estimates based on multi-pollutant models were smaller than those from single pollutant models, and those based on older populations were larger than those based on younger populations, but these differences were not statistically significant. CONCLUSIONS: We concluded that there is a likely causal relationship between short term NO2 exposure and IHD-related morbidity, but important uncertainties remain, particularly related to the contribution of co-pollutants or other concomitant exposures, and the lack of supporting evidence from toxicological and controlled human studies.
