Disparities in health outcomes among seniors without a family physician in the North West Local Health Integration Network: a retrospective cohort study

Social determinants of health and sepsis: a case-control study

PURPOSE

We aimed to identify whether social determinants of health (SDoH) are associated with the development of sepsis and assess the differences between individuals living within systematically disadvantaged neighbourhoods compared with those living outside these neighbourhoods.

METHODS

We conducted a single-centre case-control study including 300 randomly selected adult patients (100 patients with sepsis and 200 patients without sepsis) admitted to the emergency department of a large academic tertiary care hospital in Hamilton, ON, Canada. We collected data on demographics and a limited set of SDoH variables, including neighbourhood household income, smoking history, social support, and history of alcohol disorder. We analyzed study data using multivariate logistic regression models.

RESULTS

The study included 100 patients with sepsis with a median [interquartile range (IQR)] age of 75 [58-84] yr and 200 patients without sepsis with a median [IQR] age of 72 [60-83] yr. Factors significantly associated with sepsis included arrival by ambulance, absence of a family physician, higher Hamilton Early Warning Score, and a recorded history of dyslipidemia. Important SDoH variables, such as individual or household income and race, were not available in the medical chart. In patients with SDoH available in their medical records, no SDoH was significantly associated with sepsis. Nevertheless, compared with their proportion of the Hamilton population, the rate of sepsis cases and sepsis deaths was approximately two times higher among patients living in systematically disadvantaged neighbourhoods.

CONCLUSIONS

This study revealed the lack of available SDoH data in electronic health records. Despite no association between the SDoH variables available and sepsis, we found a higher rate of sepsis cases and sepsis deaths among individuals living in systematically disadvantaged neighbourhoods. Including SDoH in electronic health records is crucial to study their effect on the risk of sepsis and to provide equitable care.

Trends in attachment to a primary care provider in Ontario, 2008-2018: an interrupted time-series analysis

BACKGROUND

Attachment to a regular primary care provider is associated with better health outcomes, but 15% of people in Canada lack a consistent source of ongoing primary care. We sought to evaluate trends in attachment to a primary care provider in Ontario in 2008-2018, through an equity lens and in relation to policy changes in implementation of payment reforms and team-based care.

METHODS

Using linked, population-level administrative data, we conducted a retrospective observational study to calculate rates of patients attached to a regular primary care provider from Apr. 1, 2008, to Mar. 31, 2019. We evaluated the association of patient characteristics and attachment in 2018 using sex-stratified, adjusted, multivariable logistic regression models and used segmented piecewise regression to evaluate changing trends before and after implementation of a policy that restricted physician entry to alternate models.

RESULTS

Attachment increased from 80.5% (n = 10 352 385) in 2008 to 88.9% of the population (n = 12 537 172) in 2018, but was lower among people with low comorbidity, high residential instability, material deprivation, rural residence and recent immigrants. Inequities narrowed for recent immigrants, males and people with lower incomes over the study period, but disparities persisted for these groups. Attachment grew by 1.47% annually until 2014 (p < 0.0001), but was stagnant thereafter (annual percent change of 0.13, p = 0.16).

INTERPRETATION

Lack of sustained progress in attachment followed reduced levels of physician entry to alternate funding models. Although disparities narrowed for many groups over the study period, persistent gaps remained for immigrants and people with lower incomes; targeted interventions and policy changes are needed to address these persistent gaps.

Evaluation of the implementation of single points of access for unattached patients in primary care and their effects: a study protocol

INTRODUCTION

Attachment to a primary care provider is an important component of primary care as it facilitates access. In Québec, Canada, attachment to a family physician is a concern. To address unattached patients' barriers to accessing primary care, the Ministry of Health and Social Services mandated Québec's 18 administrative regions to implement single points of access for unattached patients (Guichets d'accès première ligne (GAPs)) that aim to better orient patients towards the most appropriate services to meet their needs. The objectives of this study are to (1) analyse the implementation of GAPs, (2) measure the effects of GAPs on performance indicators and (3) assess unattached patients' experiences of navigation, access and service utilisation.

METHODS AND ANALYSIS

A longitudinal mixed-methods case study design will be conducted. Objective 1. Implementation will be analysed through semistructured interviews with key stakeholders, observations of key meetings and document analysis. Objective 2. GAP effects on indicators will be measured using performance dashboards produced using clinical and administrative data. Objective 3. Unattached patients' experiences will be assessed using a self-administered electronic questionnaire. Findings for each case will be interpreted and presented using a joint display, a visual tool for integrating qualitative and quantitative data. Intercase analyses will be conducted highlighting the similarities and differences across cases.

ETHICS AND DISSEMINATION

This study is funded by the Canadian Institutes of Health Research (# 475314) and the Fonds de Soutien à l'innovation en santé et en services sociaux (# 5-2-01) and was approved by the CISSS de la Montérégie-Centre Ethics Committee (MP-04-2023-716).

Pneumococcal vaccination uptake and missed opportunities for vaccination among Canadian adults: A cross-sectional analysis of the Canadian Longitudinal Study on Aging (CLSA)

Introduction

In Canada, pneumococcal vaccination is recommended to all adults aged ≥65 and those <65 who have one or more chronic medical conditions (CMCs). Understanding vaccine uptake and its determinants among eligible groups has important implications for reducing the burden of pneumococcal disease.

Methods

Using data from a large national cohort of Canadian residents aged ≥47 years between 2015–2018, we calculated self-reported pneumococcal vaccine uptake among eligible groups, estimated associations between key factors and non-vaccination, assessed missed opportunities for vaccination (MOV) and examined risk factors for MOV. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for relevant associations were estimated through logistic regression.

Results

45.8% (95% CI: 45.2–46.5) of 22,246 participants aged ≥65 and 81.3% (95% CI: 80.5–82.0) of 10,815 individuals aged 47–64 with ≥1 CMC reported never having received a pneumococcal vaccine. Receipt of influenza vaccination in the previous year was associated with the lowest odds of pneumococcal non-vaccination (aOR = 0.14 [95% CI: 0.13–0.15] for older adults and aOR = 0.23 [95% CI: 0.20–0.26] for those aged 47–64 with ≥1 CMC). Pneumococcal vaccine uptake was also more likely in case of contact with a family doctor in the previous year (versus no contact), increased with age and varied widely across provinces. Among individuals recently vaccinated against influenza, 32.6% (95% CI: 31.9–33.4) of those aged ≥65 and 71.1% (95% CI: 69.9–72.3) of those aged 47–64 with ≥1 CMC missed an opportunity to get a pneumococcal vaccine. Among individuals who had contact with a family doctor, 44.8% (95% CI: 44.1–45.5) of those aged ≥65 and 80.4% (95% CI: 79.6–81.2) of those aged 47–64 with ≥1 CMC experienced a MOV.

Conclusions

Pneumococcal vaccine uptake remains suboptimal among at-risk Canadian adults who are eligible for vaccination. Further research is needed to clarify the reasons behind missed opportunities for vaccination and adequately address the main barriers to pneumococcal vaccination.

Early generalist placements are associated with family medicine career choice: A systematic review and meta-analysis

INTRODUCTION

Many developed countries have reported shortages of Primary Care (PC) physicians. The lack of a regular primary physician is associated with inferior health outcomes. One strategy to address this shortage is to increase the proportion of medical students selecting a Family Medicine (FM) or PC career. The purpose of this systematic review is to identify whether pre-clerkship general practice placements increase students' interest in, and selection of FM or PC residencies.

METHODS

Three databases (PubMed, Embase, Web of Science) searched for interventional studies of pre-clerkship generalist placements in medical school. Pooled statistical analysis and meta-analysis were performed, along with narrative summaries when possible. Intervention participants (IP) were compared to controls matched (MC) for baseline interest in FM and an unmatched sample (UC) of contemporary students.

FINDINGS

A 11 studies were identified including a total of 5430 students (2428 intervention participants and 3002 controls). IPs were more likely to match to FM than both MC (Risk Ratio: 1.62 [95% CI: 1.03-2.55]) and UC (RR: 2.04 [1.46-2.86]). Participation in long interventions (4-11 weeks) matched to FM at higher rates than short (25-40 hours) interventions (RR: 3.15 [2.28-4.35]). The percentage of students with FM/PC as their top specialty of interest increased after the placements (mean difference: +12.8%, n = 586).

CONCLUSIONS

Medical students who participated in pre-clerkship general practice placements were more likely to match to a FM residency. Longer pre-clerkship placements had a stronger association with FM specialty choice. The implementation of longitudinal block generalist placements in the pre-clerkship years is one strategy for increasing interest in generalist careers.

Discharging the complex patient - changing our focus to patients' networks of care providers

Background

A disconnect exists between the idealized model of every patient having a family physician (FP) who acts as the central hub for care, and the reality of health care where patients must navigate a network of different providers. This disconnect is particularly evident when hospitalized multimorbid patients transition back into the community. These discharges are identified as high-risk due to lapses in care continuity. The aim of this study was to identify and explore the networks of care providers in a sample of hospitalized, complex patients, and better understand the nature of their attachments to these providers as a means of discovering novel approaches for improving discharge planning.

Methods

This was a constructivist grounded theory study. Data included interviews from 30 patients admitted to an inpatient internal medicine service of a midsized academic hospital in Ontario, Canada. Analysis and data collection proceeded iteratively with sampling progressing from purposive to theoretical.

Results

We identified network of care configurations commonly found in patients with multiple medical comorbidities receiving care from multiple different providers admitted to an internal medicine service. FPs and specialists form the network’s scaffold. The involvement of physicians in the network dictated not only how patients experienced transitions in care but the degree of reliance on social supports and personal capacities. The ideal for the multimorbid patient is an optimally involved FP that remains at the centre, even when patients require more subspecialized care. However, in cases where a rostered FP is non-existent or inadequate, increased involvement and advocacy from specialists is crucial.

Conclusions

Our results have implications for transition planning in hospitalized complex patients. Recognizing salient network features can help identify patients who would benefit from enhanced discharge support.
