Objective
This study aims to (1) build and validate model-based case definitions for multiple sclerosis (MS) that use trends (ie, trend-based case definitions) and (2) to apply dynamic classification to identify the average number of data years needed for classification (ie, average trend needed).

Design
Retrospective cohort study design.

Participants
608 MS cases and 59 620 MS non-cases.

Setting
Data from 1 April 2004 to 31 March 2022 were obtained from the Manitoba Population Research Data Repository. MS case status was ascertained from homecare records and linked to health data. Trend-based case definitions were constructed using multivariate generalised linear mixed models applied to annual numbers of general and specialist physician visits, hospitalisations and MS healthcare contacts or medication dispensations. Dynamic classification, which ascertains cases and non-cases annually, was used to estimate mean classification time. Classification accuracy performance measures, including sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), proportion correctly classified (PCC) and F1-scores, were compared for trend-based case definitions and a deterministic case definition of 3+MS healthcare contacts or medication dispensations.

Results
When applied to the full study period, classification accuracy performance measure estimates for all case definitions exceeded 0.90, except sensitivity and PPV for the trend-based dynamic case definition (0.88, 0.64, respectively). PCC was high for all case definitions (0.94–0.99); F1-scores were lower for the trend-based case definitions compared with the deterministic case definition (0.74–0.93 vs 0.96). Dynamic classification identified 5 years as the average trend needed. When applied to the average trend windows, accuracy estimates for trend-based case definitions were lower than the estimates from the full study period (sensitivity: 0.77–0.89; specificity: 0.90–0.97; PPV: 0.54–0.81; NPV: 0.97–0.99; F1-score: 0.64–0.84). Accuracy estimates for the deterministic case definition remained high, except sensitivity (0.42–0.80). F1-score was variable (0.59–0.89).

Conclusions
Trend-based and deterministic case definitions classifications were similar to a population-based clinician assessment reference standard for multiple measures of classification accuracy. However, accuracy estimates for both trend-based and deterministic case definitions varied as the years of data used for classification were reduced. Dynamic classification appears to be a viable option for identifying the average trend needed for trend-based case definitions.

Introduction
Structural and functional abnormalities in the cortical–striatal network (CSN) are hypothesised to play a key role in the pathogenesis of neurological disease-associated fatigue. Some small-scale functional MRI (fMRI) studies have suggested that poststroke fatigue (PSF) is related to focal functional connectivity (FC) changes. To date, there has been no published large-scale fMRI study on PSF. This planned study will examine the role of the CSN FC on PSF.

Methods and analysis
The planned study will be a prospective cohort study conducted at the Neurology Unit of the Prince of Wales Hospital. We will recruit 738 participants. The project duration will be 36 months. A psychiatrist will administer the Fatigue Severity Scale (FSS) at 3 months (P1) following the index stroke. PSF is defined as an FSS Score≥4.0. PSF severity will be defined by the FSS total score at P1. Participants with PSF at P1 will undergo two follow-up assessments at 9 (P2) and 15 (P3) months post stroke. PSF remission at P2 or P3 will be defined as a 50% reduction in FSS. Participants will undergo MRI examinations within 2 weeks of the 3-month poststroke assessment. Structural MRI, resting-state fMRI and diffusion tensor imaging will be performed. FC, structural connectivity, infarcts, cerebral microbleeds and white matter hyperintensities will be analysed. For the primary analysis, the effect of PSF on the FC, structural connectivity and diffusion metrics of CSN of stroke survivors, voxel-wise two-sample t-tests will be performed with FDR correction for multiple comparison and significance level set at p

Introduction
Case management (CM) is among the most studied effective models of integrated care for people with complex needs. The goal of this study is to scale up and assess CM in primary healthcare for people with complex needs.

Methods and analysis
The research questions are: (1) which mechanisms contribute to the successful scale-up of CM for people with complex needs in primary healthcare?; (2) how do contextual factors within primary healthcare organisations contribute to these mechanisms? and (3) what are the relationships between the actors, contextual factors, mechanisms and outcomes when scaling-up CM for people with complex needs in primary healthcare? We will conduct a mixed methods Canadian interprovincial project in Quebec, New-Brunswick and Nova Scotia. It will include a scale-up phase and an evaluation phase. At inception, a scale-up committee will be formed in each province to oversee the scale-up phase. We will assess scale-up using a realist evaluation guided by the RAMESES checklist to develop an initial programme theory on CM scale-up. Then we will test and refine the programme theory using a mixed-methods multiple case study with 10 cases, each case being the scalable unit of the intervention in a region. Each primary care clinic within the case will recruit 30 adult patients with complex needs who frequently use healthcare services. Qualitative data will be used to identify contexts, mechanisms and certain outcomes for developing context–mechanism–outcome configurations. Quantitative data will be used to describe patient characteristics and measure scale-up outcomes.

Ethics and dissemination
Ethics approval was obtained. Engaging researchers, decision-makers, clinicians and patient partners on the study Steering Committee will foster knowledge mobilisation and impact. The dissemination plan will be developed with the Steering Committee with messages and dissemination methods targeted for each audience.

Objectives
To explore the experiences and perspectives of community pharmacists regarding their roles during the closure stage (ie, March to May 2020) of the COVID-19 pandemic in Newfoundland and Labrador (NL), Canada.

Design
This qualitative case study included a document analysis and semistructured interviews with community pharmacists who provided direct patient care during the COVID-19 pandemic. The document analysis was used to develop a chronology that informed the interviews. Themes from qualitative interviews were developed through iterative cycles of data review and analysis using applied thematic analysis. Findings are presented specifically for the time period between March and May 2020, defined as the ‘Closure Stage’.

Setting
Community pharmacies in NL, Canada.

Results
12 community pharmacists participated in the interviews. Four themes were developed including (1) pharmacists’ leadership in continuity of care, (2) pharmacists as medication stewards, (3) pharmacists as a source of COVID-19 health information and (4) the impact of COVID-19 on pharmacists’ mental health and well-being. The first three themes described the key roles played by community pharmacists during the early days of the COVID-19 pandemic, including coordinating care, prescribing for common ailments, delivering medications and supplies, providing information on COVID-19 symptoms and their management, renewing chronic medications and protecting the medication supply. Unclear guidance on scope of practice, limited scope of practice, inadequate staffing and limited support from government bodies were identified as barriers to these roles. Facilitators included access to a delivery service, swift regulatory changes, reimbursement and support from colleagues and other healthcare professionals. The fourth theme is presented independently, emphasising the impact of working within the primary healthcare (PHC) system during the COVID-19 pandemic on pharmacists’ mental health and well-being.

Conclusion
Pharmacists played a critical role in the delivery of PHC services during the closure stage of the COVID-19 pandemic. The findings of this research highlight the essential elements of a strong PHC pandemic preparedness plan that is inclusive of community pharmacists, including improved communication strategies, mental health support and access to resources.

In 1965, President Lyndon Johnson signed Medicare into law with President Harry Truman, a longtime advocate for the program and the ostensible originator of the concept, proudly looking onwards. At the time of the signing Johnson boldly remarked, “No longer will older Americans be denied the healing miracle of modern medicine. No longer will illness crush and destroy the savings that they have so carefully put away over a lifetime so that they might enjoy dignity in their later years.”
