Classification system for primary care provider eConsults about medications for older adults with frailty.

BACKGROUND: Providing primary care for people with frailty can be challenging due to an increased risk of adverse outcomes and use of potentially inappropriate medications which may exacerbate characteristics of frailty. eConsult is a service where primary care providers can receive timely specialist advice for their patients through a secure web-based application. We aimed to develop a classification system to characterize medication-focused eConsult questions for older adults with frailty and assess its usability. METHODS: A classification system was developed and refined over three cycles of improvement through a cross-sectional study of 35 cases categorized as medication-focused from cases submitted in 2019 for patients aged 65 or older with frailty through the Champlain BASE eConsult service (Ontario, Canada). The final classification system was then applied to each case. RESULTS: The classification system contains 5 sections: (1) case descriptives; (2) intent and type of question; (3) medication recommendations and additional information in the response; (4) medication classification; and (5) potentially inappropriate medications. Among the 35 medication-focused cases, the most common specialties consulted were endocrinology (9 cases, 26%) and cardiology (5 cases, 14%). Medication histories were available for 29 cases (83%). Many patients were prescribed potentially inappropriate medications based on explicit tools (AGS Beers Criteria®, STOPPFall, Anticholinergic Cognitive Burden Scale, ThinkCascades) yet few consults inquired about these medications. CONCLUSION: A classification system to describe medication-related eConsult cases for patients experiencing frailty was developed and applied to 35 eConsult cases. It can be applied to more cases to identify professional development opportunities and enhancements for eConsult services.

Lost but not forgotten: A population-based study of mortality and care trajectories among people living with HIV who are lost to follow-up in Ontario, Canada.

OBJECTIVES: Selection as a consequence of volunteer participation in, and loss to follow-up from, cohort studies may bias estimates of mortality and other health outcomes. To quantify this potential, we estimated mortality and health service use among people living with HIV (PLWH) who were lost to cohort follow-up (LTCFU) from a volunteer clinical HIV-infected cohort, and compared these to mortality and health service use in active cohort participants and non-cohort-participants living with HIV in Ontario, Canada. METHODS: We analysed population-based provincial health databases from 1995 to 2014, identifying PLWH ≥ 18 years old; these included data from participants in the Ontario HIV Treatment Network Cohort Study (OCS), a volunteer, multi-site clinical HIV-infected cohort. We calculated all-cause mortality, hospitalization and emergency department (ED) visit rates per 100 person-years (PY) and estimated hazard ratios (HRs) of mortality, adjusting for age, sex, income, rurality, and immigration status. RESULTS: Among 23 043 PLWH, 5568 were OCS participants. Compared with nonparticipants, participants were younger and less likely to be female, to be an immigrant and to reside in a major urban centre, and had lower comorbidity. Mortality among active participants, participants LTCFU and nonparticipants was 2.52, 3.30 and 2.20 per 100 PY, respectively. After adjustment for covariates, mortality risk was elevated among participants LTCFU compared with active participants (HR 2.26; 95% confidence interval 1.91, 2.68). Age-adjusted hospitalization rates and ED visit rates were highest among participants LTCFU. CONCLUSIONS: Mortality risk and use of health care resources were lower among active cohort participants. Our findings may inform health outcome estimates based on volunteer cohorts, as well as quantitative bias adjustment to correct for such biases.

An environmental scan of policies in support of chronic disease self-management in Canada.

INTRODUCTION: The evidence supporting chronic disease self-management warrants further attention. Our aim was to identify existing policies, strategies and frameworks that support self-management initiatives. METHODS: This descriptive study was conducted as an environmental scan, consisting of an Internet search of government and other publicly available websites, and interviews with jurisdictional representatives identified through the Health Council of Canada and academic networking. RESULTS: We interviewed 16 representatives from all provinces and territories in Canada and found 30 publicly available and relevant provincial and national documents. Most provinces and territories have policies that incorporate aspects of chronic disease self-management. Alberta and British Columbia have the most detailed policies. Both feature primary care prominently and are not disease specific. Both also have provincial level implementation of chronic disease self-management programming. Canada's northern territories all lacked specific policies supporting chronic disease self-management despite a significant burden of disease. CONCLUSION: Engaging patients in self-management of their chronic diseases is important and effective. Although most provinces and territories have policies that incorporate aspects of chronic disease self-management, they were often embedded within other initiatives and/or policy documents framed around specific diseases or populations. This approach could limit the potential reach and effect of self-management.

TITRE: Analyse contextuelle des politiques à l'appui de l'auto-prise en charge des maladies chroniques au Canada. INTRODUCTION: Les données probantes appuyant l'auto-prise en charge des maladies chroniques méritent de faire l'objet d'une analyse plus approfondie. Notre objectif était de cerner les politiques, les stratégies et les cadres existants à l'appui des initiatives d'auto-prise en charge. MÉTHODOLOGIE: La présente étude descriptive a été effectuée sous forme d'analyse contextuelle. Elle comprend une recherche sur les sites Web gouvernementaux et d'autres sites Web accessibles au public ainsi que des entrevues avec des représentants gouvernementaux choisis par l'entremise du Conseil canadien de la santé et par réseautage universitaire. RÉSULTATS: Nous avons interviewé 16 représentants de toutes les provinces et de tous les territoires du Canada et nous avons relevé 30 documents provinciaux et nationaux d'intérêt accessibles au public. La plupart des provinces et des territoires possèdent des politiques dont certains éléments portent sur l'auto-prise en charge des maladies chroniques. Les politiques de l'Alberta et de la Colombie-Britannique sont les plus détaillées. Elles accordent une place de choix aux soins primaires et elles ne sont pas axées sur une maladie en particulier. Elles présentent également des mesures pour la mise en oeuvre à l'échelle provinciale des programmes d'auto-prise en charge des maladies chroniques. L'ensemble des territoires du nord du Canada n'avait pas de politiques précises sur l'auto-prise en charge des maladies chroniques, malgré un lourd fardeau associé à ces maladies. CONCLUSION: Faire participer les patients à l'auto-prise en charge de leur maladie chronique est important et efficace. Même si la plupart des provinces et des territoires possèdent des politiques qui comportent des éléments liés à l'auto-prise en charge des maladies chroniques, ces politiques sont souvent intégrées à d'autres initiatives ou d'autres documents de politiques axés sur des maladies ou des populations en particulier, ce qui peut limiter la portée et l'effet potentiels de l'auto-prise en charge.

The Community Connection Model: implementation of best evidence into practice for self-management of chronic diseases.

OBJECTIVE: With chronic diseases becoming an increasing burden for healthcare systems worldwide, self-management support has gained traction in many health regions and organizations. However, the real-world application of the findings from clinical trials into actual community programming is not self-evident. The aim of this study was to present a model of programme implementation, namely the Community Connection Model. METHODS: The process of implementing a chronic disease self-management programme has been documented in detail from its initial inception through to a sustainable programme. This account includes a description of the strategic activities undertaken (e.g. alignment with local policy and the formation of community partnerships) and the specific steps taken on the path to programme implementation (e.g. a scoping literature review, an environmental scan and a pilot programme with an evaluation component). RESULTS: Reflection on this case example suggests that a cognizance of the interactions between policy, partnership, planning and programme could act as a useful tool to guide programme implementation, evaluation and sustainability. RESULTS: Multiple types of self-management support have been implemented (as part of the Living Health Champlain programme), and are being evaluated and adapted in response to new evidence, shifting priorities and direction from more partners. The widespread access means that self-management support programmes are becoming part of the culture of care in the study region. CONCLUSION: Establishing a connection around an important health problem, ensuring active partnerships, adequate planning and early implementation of a programme grounded on the principles of applying best-available evidence can lead to successful solutions. The Community Connection Model is proposed as a way of conceptualizing these processes.

Endomysial antibody detection using human umbilical cord tissue as substrate: reactivity of cells in Wharton's jelly.

The measurement of immunoglobulin A (IgA) endomysial antibodies is now established as an important diagnostic test in gluten-sensitive disease. Monkey oesophagus is the commonly used tissue substrate, but it has been proposed that human umbilical cord tissue may be a suitable alternative for antibody detection. In this study, we report a modified method of examining endomysial antibody reactivity with cord tissue. This involves examination of antibody reactivity with cells in Wharton's jelly, and with umbilical cord blood vessel. A total of 370 patients being investigated for coeliac disease were studied and this diagnosis was established in 42. Endomysial antibodies were found in all 42 using umbilical cord tissue, and the test results were confirmed with monkey oesophagus substrate. In three of the remaining 328 non-coeliacs, a false-positive endomysial antibody test was noted and small intestine histology was normal in these patients. All positive sera were found to react with cells in Wharton's jelly, and reticular staining of blood vessels was also present. Examination for immunofluorescence in both Wharton's jelly and blood vessel components of cord tissue greatly simplified test interpretation.

High prevalence of celiac disease among patients with insulin-dependent (type I) diabetes mellitus.

OBJECTIVES: Diagnosis of unrecognized celiac disease is potentially important. The prevalence of celiac disease in patients with insulin-dependent diabetes mellitus is uncertain. We report the prevalence of celiac disease in a stratified random sample (n = 101) of adult insulin-dependent diabetic patients (age, 18-59 yr) attending our clinic, and in an age- and sex-matched control group (n = 51). METHODS: Screening was by anti-endomysial antibody, measured by indirect immunofluorescence using sections of human umbilical cord. RESULTS: Celiac disease had not been suspected in any patient at the time of screening. Eight patients tested positive for anti-endomysial antibody, all of whom had a distal duodenal biopsy performed. Five patients had histologic evidence of celiac disease. One patient with negative histology was receiving immunosuppressive therapy for a renal-pancreas transplant. Of the five patients with abnormal histology, two improved on gluten restriction, one was unable to comply, one refused treatment, and one was lost to follow-up. No control subject tested positive for endomysial antibody. CONCLUSIONS: Patients with insulin-dependent diabetes have an increased prevalence of celiac disease. Because most cases are clinically unrecognized, consideration should be given to screening all insulin-dependent diabetes mellitus patients with endomysial antibodies.
