RESUMO
BACKGROUND: The COVID-19 pandemic has reshaped healthcare delivery worldwide. OBJECTIVE: To explore potential changes in the reasons for visits and modality of care in primary care settings through the International Consortium of Primary Care Big Data Researchers (INTRePID). METHODS: We conducted a cross-sectional, retrospective study from 2018-2021. We examined visit volume, modality, and reasons for visits to primary care in Argentina, Australia, Canada, China, Peru, Norway, Singapore, Sweden, and the USA. The analysis involved a comparison between the pre-pandemic and pandemic periods. RESULTS: There were more than 215 million visits from over 38 million patients during the study period in INTRePID primary care settings. Most INTRePID countries experienced a decline in monthly visit rates during the first year of the pandemic, with rate ratios (RR) and 95% confidence intervals (CI) ranging from RR:0.57 (95%CI:0.49-0.66) to RR:0.90 (95%CI:0.83-0.98), except for in Canada (RR:0.99, 95%CI:0.94-1.05) and Norway (RR:1.00, 95%CI:0.92-1.10), where rates remained stable and in Australia where rates increased (RR:1.19, 95%CI:1.11-1.28). Argentina, China, and Singapore had limited or no adoption of virtual care, whereas the remaining INTRePID countries varied in the extent of virtual care utilization. In Peru, virtual visits accounted for 7.34% (95%CI:7.33%-7.35%) of all interactions in the initial year of the pandemic, dipping to 5.22% (95%CI:5.21%-5.23%) in the subsequent year. However, in Canada 75.30% (95%CI:75.20%-75.40%) of the visits in the first year were virtual, decreasing to 62.77% (95%CI:62.66%-62.88%) in the second year. Diabetes, hypertension and/or hyperlipidemia and general health exams were in the top 10 reasons for visits in 2019 for all countries. Anxiety, depression and/or other mental health related reasons were among the top 10 reasons for virtual visits in all countries that had virtual care. CONCLUSIONS: The pandemic resulted in changes in reasons for visits to primary care, with virtual care mitigating visit volume disruptions in many countries.
RESUMO
BACKGROUND: Despite many atrial fibrillation (AF) patients being at risk of bleeding, very limited data are available on bleeding rates of different direct oral anticoagulants (DOACs) based on the spectrum of bleeding risk. OBJECTIVE: To compare the risk of major bleeding and thromboembolic events with apixaban versus rivaroxaban among AF patients, stratified by bleeding risk. METHODS: We conducted a population-based, retrospective cohort study of all adult patients (66 years or older) with AF in Ontario, Canada, who were treated with apixaban or rivaroxaban between April 1, 2011 and March 31, 2020. Bleeding risk was estimated using the HAS-BLED score with high bleeding risk defined as a score of 3 or greater. The primary safety outcome was major bleeding and the primary efficacy outcome was thromboembolic events. Comparisons were adjusted for baseline comorbidities using inverse probability of treatment weighting (IPTW). RESULTS: This study included 18,156 AF patients with high bleeding risk and 55,186 AF patients with low bleeding risk. Apixaban use was more common in high bleeding risk patients; 63% of high risk patients used apixaban compared to 56% of low risk patients. Apixaban users had lower rates of major bleeding in high risk patients (2.9% vs 4.2% per year; HR 0.69 [95%CI, 0.58-0.81]) and in low risk patients (1.8% vs 2.9% per year; HR 0.63 [95%CI, 0.56-0.70]), compared with rivaroxaban. There were no differences in rates of thromboembolic events 3.1% vs 3.0% per year (HR 1.02 [95%CI, 0.86-1.22]) in high risk patients and 1.9% vs 1.9% per year (HR 1.00 [95%CI, 0.89-1.14]) in low risk patients. CONCLUSIONS: Among older AF patients with high or low bleeding risk, treatment with apixaban was associated with lower rates of major bleeding with no difference in risk for thromboembolic events compared with rivaroxaban.
RESUMO
Background: Hypertension Canada 2017 guidelines favoured the use of thiazide (TZ)-like diuretics, such as CLTD (chlorthalidone) and indapamide (IND) over hydrochlorothiazide (HCTZ). Health Canada warned in 2019 that HCTZ may be associated with increased risk of skin cancer. Our study looked at the changes in TZ prescriptions from 2015 to 2021 in Ontario, Canada. Methods: A retrospective cohort study was conducted of adults with hypertension, using electronic medical record data from the University of Toronto Practice-Based Research Network database covering mostly the Greater Toronto area. Outcomes included the proportion of patients who received a prescription of HCTZ, CLTD, or IND each month. Interrupted time-series analysis was used to evaluate the change in outcomes after publication of the 2017 guidelines and 2019 safety warning. Prescription trends were stratified by prescribing physicians' sex and year of medical school graduation. Results: A total of 100,428 patients with hypertension were included in the cohort, with 31,700 patients who received at least one TZ prescription from 343 family physicians. We found a declining trend in HCTZ prescriptions over time, accompanied by an increase in IND and CLTD prescriptions, with statistically significant but transient changes in prescription rates after publication of the 2017 guidelines and the 2019 safety warning for all 3 medications. Female physician and early-career physician prescription rates changed faster than that of their counterparts immediately after the Health Canada safety warning was issued. Conclusions: TZ diuretic prescription patterns have changed in recent years, but Hypertension Canada's 2017 guidelines and the 2019 Health Canada safety warning did not have a sustained significant impact on the change in prescription rates of HCTZ, IND, and CLTD.
Contexte: Les lignes directrices 2017 d'Hypertension Canada accordaient la priorité à l'utilisation de diurétiques apparentés aux thiazidiques (TZ), comme la chlorthalidone (CLTD) et l'indapamide (IND), plutôt que l'hydrochlorothiazide (HCTZ). En 2019, Santé Canada a émis une mise en garde indiquant que le HCTZ pourrait être associé à un risque accru de cancer de la peau. Notre étude s'intéressait à l'évolution des taux de prescriptions des différents diurétiques TZ entre 2015 et 2021 en Ontario, au Canada. Méthodologie: Une étude de cohorte rétrospective a été menée auprès d'adultes atteints d'hypertension à l'aide des données des dossiers médicaux électroniques du réseau de recherche fondé sur la pratique de l'Université de Toronto, qui couvre principalement la région du Grand Toronto. Les issues évaluées comprenaient la proportion de patients se faisant prescrire HCTZ, CLTD ou IND chaque mois. Une analyse de série chronologique interrompue a été réalisée pour évaluer l'évolution des issues après la publication des lignes directrices de 2017 et la mise en garde de 2019. Les tendances observées dans les prescriptions ont été stratifiées selon le sexe et l'année d'obtention du diplôme de médecine du médecin prescripteur. Résultats: Au total, 100 428 patients atteints d'hypertension ont été inclus dans la cohorte; 31 700 d'entre eux se sont fait prescrire un TZ au moins une fois par l'un des 343 médecins de famille prescripteurs. Nous avons observé une tendance à la baisse quant aux prescriptions de HCTZ, laquelle s'accompagnait d'une augmentation du nombre de prescriptions d'IND et de CLTD. La variation des taux de prescriptions pour les trois médicaments était statistiquement significative, mais transitoire après la publication des lignes directrices de 2017 et de la mise en garde de 2019. Les taux de prescriptions immédiatement après la publication de la mise en garde de Santé Canada ont changé plus vite pour les femmes médecins et les médecins en début de carrière que pour les autres médecins. Conclusions: Les habitudes de prescription des diurétiques thiazidiques ont changé dans les dernières années, mais les lignes directrices 2017 d'Hypertension Canada et la mise en garde émise en 2019 par Santé Canada n'ont pas eu un effet significatif durable sur la variation des taux de prescriptions de HCTZ, d'IND et de CLTD.
RESUMO
Objectives: The majority of patients with respiratory illness are seen in primary care settings. Given COVID-19 is predominantly a respiratory illness, the INTernational ConsoRtium of Primary Care BIg Data Researchers (INTRePID), assessed the pandemic impact on primary care visits for respiratory illnesses. Design: Definitions for respiratory illness types were agreed on collectively. Monthly visit counts with diagnosis were shared centrally for analysis. Setting: Primary care settings in Argentina, Australia, Canada, China, Norway, Peru, Singapore, Sweden and the United States. Participants: Over 38 million patients seen in primary care settings in INTRePID countries before and during the pandemic, from January 1st, 2018, to December 31st, 2021. Main outcome measures: Relative change in the monthly mean number of visits before and after the onset of the pandemic for acute infectious respiratory disease visits including influenza, upper and lower respiratory tract infections and chronic respiratory disease visits including asthma, chronic obstructive pulmonary disease, respiratory allergies, and other respiratory diseases. Results: INTRePID countries reported a marked decrease in the average monthly visits for respiratory illness. Changes in visits varied from -10.9% [95% confidence interval (CI): -33.1 to +11.3%] in Norway to -79.9% (95% CI: -86.4% to -73.4%) in China for acute infectious respiratory disease visits and - 2.1% (95% CI: -12.1 to +7.8%) in Peru to -59.9% (95% CI: -68.6% to -51.3%) in China for chronic respiratory illness visits. While seasonal variation in allergic respiratory illness continued during the pandemic, there was essentially no spike in influenza illness during the first 2 years of the pandemic. Conclusion: The COVID-19 pandemic had a major impact on primary care visits for respiratory presentations. Primary care continued to provide services for respiratory illness, although there was a decrease in infectious illness during the COVID pandemic. Understanding the role of primary care may provide valuable information for COVID-19 recovery efforts and planning for future global emergencies.
RESUMO
BACKGROUND: There are no clinical trials with a head-to-head comparison between the 2 most commonly used oral anticoagulants (apixaban and rivaroxaban) in patients with atrial fibrillation (AF). The comparative efficacy and safety between these drugs remain unclear, especially in older patients who are at the highest risk for stroke and bleeding. OBJECTIVE: The purpose of this study was to compare the risk of major bleeding and thromboembolic events between apixaban and rivaroxaban in older patients with AF. METHODS: We conducted a population-based retrospective cohort study of all adult patients (66 years or older) with AF in Ontario, Canada, who were treated with apixaban or rivaroxaban between April 1, 2011, and March 31, 2020. The primary safety outcome was major bleeding, and the primary efficacy outcome was thromboembolic events. Secondary outcomes included any bleeding. Rates and hazard ratios (HRs) were adjusted for baseline comorbidities with inverse probability of treatment weighting. RESULTS: This study included 42,617 patients with AF treated with apixaban and 30,725 patients treated with rivaroxaban. After inverse probability of treatment weighting using the propensity score, patients in the apixaban and rivaroxaban groups were well balanced for baseline values of demographic characteristics, comorbidities, and medications; both groups had a similar mean age of 77.4 years, and 49.9% were female. At 1 year, the apixaban group had a lower risk for both major bleeding with an absolute risk reduction at 1 year of 1.1% (2.1% vs 3.2%; HR 0.65; 95% confidence interval [CI] 0.59-0.71]) and any bleeding (8.1% vs 10.9%; HR 0.73; 95% CI 0.69-0.77), with no difference in the risk for thromboembolic events (2.2% vs 2.2%; HR 1.02; 95% CI 0.92-1.13). CONCLUSION: In patients with AF, 66 years or older, treatment with apixaban was associated with lower risk for major bleeding, with no difference in the risk for thromboembolic events compared with rivaroxaban.
RESUMO
STUDY DESIGN: Descriptive repeated-cross sectional retrospective longitudinal cohort study. OBJECTIVE: To investigate the impact of the COVID-19 pandemic on homecare services in individuals with traumatic or non-traumatic Spinal Cord Injury (SCI). SETTING: Health administrative database in Ontario, Canada. METHODS: A repeated cross-sectional study using linked health administrative databases from March 2015 to June 2022. Monthly homecare utilization was assessed in 3381 adults with SCI using Autoregressive Integrated Moving Average (ARIMA) models. RESULTS: Compared to pre-pandemic levels, between March 2020 to June 2022, the traumatic group experienced a decrease in personal and/or homemaking services, as well as an increase in nursing visits from April 2020-March 2022 and June 2022. Case management increased at various times for the traumatic group, however therapies decreased in May 2020 only. The non-traumatic group experienced a decrease in personal and/or homemaking services in July 2020, as well as an increase in nursing visits from March 2020 to February 2021 and sporadically throughout 2020. Case management also increased at certain points for the non-traumatic group, but therapies decreased in April 2020, July 2020, and September 2021. CONCLUSION: The traumatic group had decreases in personal and/or homemaking services. Both groups had increases in nursing services, increases in case management, and minimal decreases in therapies at varying times during the pandemic. Investigation is warranted to understand the root cause of these changes, and if they resulted in adverse outcomes.

BACKGROUND: A lack of consensus exists across guidelines as to which risk model should be used for the primary prevention of cardiovascular disease (CVD). Our objective was to determine potential improvements in the number needed to treat (NNT) and number of events prevented (NEP) using different risk models in patients eligible for risk stratification. METHODS: A retrospective observational cohort was assembled from primary care patients in Ontario, Canada between January 1st, 2010, to December 31st, 2014 and followed for up to 5 years. Risk estimation was undertaken in patients 40-75 years of age, without CVD, diabetes, or chronic kidney disease using the Framingham Risk Score (FRS), Pooled Cohort Equations (PCEs), a recalibrated FRS (R-FRS), Systematic Coronary Risk Evaluation 2 (SCORE2), and the low-risk region recalibrated SCORE2 (LR-SCORE2). RESULTS: The cohort consisted of 47,399 patients (59% women, mean age 54). The NNT with statins was lowest for SCORE2 at 40, followed by LR-SCORE2 at 41, R-FRS at 43, PCEs at 55, and FRS at 65. Models that selected for individuals with a lower NNT recommended statins to fewer, but higher risk patients. For instance, SCORE2 recommended statins to 7.9% of patients (5-year CVD incidence 5.92%). The FRS, however, recommended statins to 34.6% of patients (5-year CVD incidence 4.01%). Accordingly, the NEP was highest for the FRS at 406 and lowest for SCORE2 at 156. CONCLUSIONS: Newer models such as SCORE2 may improve statin allocation to higher risk groups with a lower NNT but prevent fewer events at the population level.
RESUMO
Background: The COVID-19 pandemic impacted mental health disorders, affecting both individuals with pre-existing conditions and those with no prior history. However, there is limited evidence regarding the pandemic's impact on mental health visits to primary care physicians. The International Consortium of Primary Care Big Data Researchers (INTRePID) explored primary care visit trends related to mental health conditions in Argentina, Australia, Canada, China, Norway, Peru, Singapore, Sweden, and the USA. Methods: We conducted an interrupted time series analysis in nine countries to examine changes in rates of monthly mental health visits to primary care settings from January 1st, 2018, to December 31st, 2021. Sub-group analysis considered service type (in-person/virtual) and six categories of mental health conditions (anxiety/depression, bipolar/schizophrenia/other psychotic disorders, sleep disorders, dementia, ADHD/eating disorders, and substance use disorder). Findings: Mental health visit rates increased after the onset of the pandemic in most countries. In Argentina, Canada, China, Norway, Peru, and Singapore, this increase was immediate ranged from an incidence rate ratio of 1·118 [95% CI 1.053-1.187] to 2.240 [95% CI 2.057-2.439] when comparing the first month of pandemic with the pre-pandemic trend. Increases in the following months varied across countries. Anxiety/depression was the leading reason for mental health visits in most countries. Virtual visits were reported in Australia, Canada, Norway, Peru, Sweden, and the USA, accounting for up to 40% of the total mental health visits. Interpretation: Findings suggest an overall increase in mental health visits, driven largely by anxiety/depression. During the COVID-19 pandemic, many of the studied countries adopted virtual care in particular for mental health visits. Primary care plays a crucial role in addressing mental ill-health in times of crisis. Funding: Canadian Institutes of Health Research grant #173094 and the Rathlyn Foundation Primary Care EMR Research and Discovery Fund.
RESUMO
BACKGROUND: Individuals with spinal cord injuries or disease (SCI/D) require frequent healthcare services. The COVID-19 pandemic may have impacted healthcare. Furthermore, due to secondary health conditions and comorbidities persons with SCI/D are at increased risk of experiencing severe symptoms or outcomes if infected with the COVID-19 virus. It is unclear to what extent research has investigated the pandemic and virus impacts on the SCI/D population. OBJECTIVE: To identify and summarize what is reported in the literature on the impact the COVID-19 virus and pandemic had on healthcare, health outcomes, and experiences in the adult SCI/D population. METHODS: Electronic databases and grey literature were searched for articles that included an adult population with a SCI/D and investigated the impact the COVID-19 virus and pandemic had on healthcare-related outcomes and experiences. Articles were double screened, and data were extracted, and synthesized to provide a descriptive summary of the findings. RESULTS: Twenty-four studies were included in this review with eight qualitative, fifteen quantitative, and one mixed methods study. Sixteen studies investigated healthcare utilization/access; nine investigated care delivery, nine investigated patient outcomes, and eight investigated patient experiences, with multiple studies spanning different categories of investigation. The pandemic was detrimental to healthcare utilization, access, and outcomes, but no studies quantified these changes. Virtual care was well-received by the SCI/D population to maintain continuity of care. The SCI/D population had issues with maintaining caregiving support. It was unclear if the COVID-19 virus infection impacted individuals with SCI/D differently than the general population. CONCLUSIONS: This scoping review found the pandemic negatively impacted multiple aspects of healthcare in individuals with SCI/D, however further investigation on health outcomes is required. More research, particularly large-scale quantitative studies, investigating healthcare access, utilization, and delivery, as well as patient outcomes and experiences is needed to improve care in the SCI/D population post-pandemic onset.

STUDY DESIGN: A retrospective cross-sectional study. OBJECTIVE: To identify who prescribes outpatient antibiotics among a primary care spinal cord injury (SCI) cohort. SETTING: ICES databases in Ontario, Canada. METHODS: A cohort of individuals with SCI were retrospectively identified using a tested-algorithm and chart reviews in a primary care electronic medical records database. The cohort was linked to a drug dispensing database to obtain outpatient antibiotic prescribing information, and prescriber details were obtained from a physician database. RESULTS: Final cohort included three hundred and twenty individuals with SCI. The average annual number of antibiotic courses dispensed for the SCI cohort was 2.0 ± 6.2. For dispensed antibiotics, 58.9% were prescribed by rostered-primary care practice physicians, compared to 17.9% by emergency and non-rostered primary care physicians, 17.4% by specialists and 6.1% by non-physician prescribers. Those who lived in urban areas and rural areas, compared to those who lived in suburban areas, were more likely to receive antibiotics from emergency and non-rostered primary care physicians than from rostered-primary care practice physicians. CONCLUSION: Although individuals with SCI received outpatient antibiotic prescriptions from multiple sources, physicians from an individual's rostered-primary care practice were the main antibiotic prescribers. As such, interventions to optimize antibiotics use in the SCI population should target the primary care practice.

OBJECTIVES: Existing tools to predict the risk of complications among people with type 2 diabetes poorly discriminate high- from low-risk patients. Our aim in this study was to develop risk prediction scores for major type 2 diabetes complications using real-world clinical care data, and to externally validate these risk scores in a different jurisdiction. METHODS: Using health-care administrative data and electronic medical records data, risk scores were derived using data from 25,088 people with type 2 diabetes from the Canadian province of Ontario, followed between 2002 and 2017. Scores were developed for major clinically important microvascular events (treatment for retinopathy, foot ulcer, incident end-stage renal disease), cardiovascular disease events (acute myocardial infarction, heart failure, stroke, amputation), and mortality (cardiovascular, noncardiovascular, all-cause). They were then externally validated using the independent data of 11,416 people with type 2 diabetes from the province of Manitoba. RESULTS: The 10 derived risk scores had moderate to excellent discrimination in the independent validation cohort, ranging from 0.705 to 0.977. Their calibration to predict 5-year risk was excellent across most levels of predicted risk, albeit with some displaying underestimation at the highest levels of predicted risk. CONCLUSIONS: The DIabeteS COmplications (DISCO) risk scores for major type 2 diabetes complications were derived and externally validated using contemporary real-world clinical data. As a result, they may be more accurate than other risk prediction scores derived using randomized trial data. The use of more accurate risk scores in clinical practice will help improve personalization of clinical care for patients with type 2 diabetes.

The COVID-19 pandemic has led to an increase in the prevalence of substance use presentations. This study aims to assess the impact of the COVID-19 pandemic on the rate of primary care visits for substance use including tobacco, alcohol, and other drug use among primary care patients in Ontario, Canada. Diagnostic and service fee code data were collected from a longitudinal cohort of family medicine patients during pre-pandemic (March 14, 2019-March 13, 2020) and pandemic periods (March 14, 2020-March 13, 2021). Generalized linear models were used to compare the rate of substance-use related visits pre-pandemic and during the pandemic. The effects of demographic characteristics including age, sex, and income quintile were also assessed. Relative to the pre-pandemic period, patients were less likely to have a primary care visit during the pandemic for tobacco-use related reasons (OR = 0.288, 95% CI [0.270-0.308]), and for alcohol-use related reasons (OR = 0.851, 95% CI [0.780-0.929]). In contrast, patients were more likely to have a primary care visit for other drug-use related reasons (OR = 1.150, 95% CI [1.080-1.225]). In the face of a known increase in substance use during the COVID-19 pandemic, a decrease in substance use-related primary care visits likely represents an unmet need for this patient population. This study highlights the importance of continued research in the field of substance use, especially in periods of heightened vulnerability such as during the COVID-19 pandemic.

Background: Primary care electronic medical record (EMR) data can be used to identify, manage, and screen hypertension cases. However, this approach relies on completeness and accessibility of documented blood pressure (BP) values. With the large switch to virtual care due to the COVID-19 pandemic, we assessed BP documentation in primary care EMRs during the pandemic, across patient and physician groups. Methods: Hypertension-related visits were identified during the pre-pandemic (January 2017 to February 2020) and pandemic (March 2020 to December 2021) periods from a primary care EMR database in Ontario, Canada. Clustered logistic regression models were used to analyze the relationship of physician and patient characteristics with an outcome variable of documented BP. A chart review of 3200 hypertension visits without a BP recorded in structured data fields was conducted to determine if BP was recorded in progress notes. Results: Pre-pandemic, 75.7% of hypertension-related visits (113,966 of 150,511) had a BP recorded in structured documentation, but this significantly decreased to 36.4% (26,660 of 73,239) during the pandemic (odds ratio [OR] = 0.18, 95% confidence interval [CI]: 0.18-0.19). For virtual visits, 14.3% (6357 of 44,572) had a documented BP, vs 74.0% (20,056 of 27,089) for in-person visits. Chart review found that 55.9% of hypertension visits had no associated BP in structured documentation, but did have a BP recorded in the progress note. Male providers, compared to female providers, were less likely to record BPs pre-pandemic (OR = 0.45, 95% CI: 0.32-0.63) and during the pandemic, for both virtual visits (OR = 0.48, 95% CI: 0.32-0.71) and in-person visits (OR = 0.46, 95% CI: 0.33-0.64). Conclusions: BP documented in primary care EMRs declined during the pandemic, most likely due to high rates of virtual visits impacting hypertension detection and management.
Contexte: Les données des dossiers médicaux électroniques (DME) provenant des soins primaires peuvent être utilisées pour détecter, prendre en charge et dépister les cas d'hypertension. Cependant, cette approche dépend de l'accessibilité et de l'exhaustivité des valeurs de pression artérielle (PA) consignées aux dossiers. Étant donné l'important passage aux soins virtuels attribuable à la pandémie de COVID-19, nous avons évalué la façon dont la PA avait été consignée dans les DME de soins primaires pendant la pandémie, parmi des groupes de patients et de médecins. Méthodologie: Les consultations liées à l'hypertension pendant les périodes pré-pandémique (de janvier 2017 à février 2020) et pandémique (de mars 2020 à décembre 2021) ont été recueillies d'une banque de données de DME de soins primaires en Ontario (Canada). Des modèles de régression logistique regroupée ont été utilisés pour analyser le lien entre les caractéristiques des médecins et de patients et une variable de résultats des PA consignées. Une revue des dossiers portant sur 3200 consultations pour hypertension sans consignation de la PA dans les champs de données structurés a été effectuée afin de déterminer si la PA avait été notée dans les notes d'évolution. Résultats: Avant la pandémie, la PA avait été consignée dans une documentation structurée pour 75,7 % (113 966 sur 150 511) des consultations pour hypertension, mais cette proportion a chuté considérablement à 36,4 % (26 660 sur 73 239) pendant la pandémie (rapport des cotes [RC] = 0,18; intervalle de confiance [IC] à 95 % : 0,18-0,19). Pour ce qui est des consultations virtuelles, la PA a été consignée dans 14,3 % (6357 sur 44 572) des cas, comparativement à 74,0 % (20 056 sur 27 089) pour les consultations en personne. Une analyse des dossiers a révélé que pour 55,9 % des consultations pour hypertension, aucune mesure de PA ne figurait dans la documentation structurée, mais qu'une valeur de PA avait toutefois été consignée dans les notes d'évolution. Les professionnels de la santé masculins, comparativement aux femmes, ont été moins susceptibles de consigner les valeurs de PA avant la pandémie (RC = 0,45; IC à 95 % : 0,32-0,63) et pendant la pandémie, tant lors des consultations virtuelles (RC = 0,48; IC à 95 % : 0,32-0,71) que des consultations en personne (RC = 0,46; IC à 95 % : 0,33-0,64). Conclusions: L'inscription des valeurs de PA dans les DME de soins primaires a décliné pendant la pandémie, fort probablement en raison de la proportion élevée de consultations virtuelles, ce qui a eu une incidence sur la détection et la prise en charge de l'hypertension.
RESUMO
Background: Individuals with a spinal cord injury (SCI) are considered higher users of antibiotics. However, to date there have been no detailed studies investigating outpatient antibiotic use in this population. Objectives: (1) To describe primary care antibiotic prescribing patterns in adults with SCI rostered to a primary care physician (PCP), and (2) to identify patient or PCP factors associated with number of antibiotics prescribed and antibiotic prescription duration. Methods: A retrospective cohort study using linked health administrative and electronic medical records (EMR) databases from January 1, 2013 to December 31, 2015 among 432 adults with SCI in Ontario, Canada. Negative binomial regression analyses were conducted to identify patient or physician factors associated with number of antibiotics prescribed and prescription duration. Results: During the study period, 61.1% of the SCI cohort received an antibiotic prescription from their PCP. There were 59.8% of prescriptions for urinary tract infections (UTI) and 24.6% of prescriptions for fluoroquinolones. Regression analysis found catheter use was associated with increased number of antibiotics prescribed (relative risk [RR] = 3.1; 95% CI, 2.3-4.1; p < .001) and late career PCPs, compared to early-career PCPs, prescribed a significantly longer duration (RR = 1.8; 95% CI, 1.1-3.1; p = .02). Conclusion: UTIs were the number one prescription indication, and fluoroquinolones were the most prescribed antibiotic. Catheter use was associated with number of antibiotics, and PCP's years of practice was associated with duration. The study provided important information about primary care antibiotic prescribing in the SCI population and found that not all individuals received frequent antibiotics prescriptions.

Study objective: Develop and evaluate a model that uses health administrative data to categorize cardiovascular (CV) cause of death (COD). Design: Population-based cohort. Setting: Ontario, Canada. Participants: Decedents ≥ 40 years with known COD between 2008 and 2015 in the CANHEART cohort, split into derivation (2008 to 2012; n = 363,778) and validation (2013 to 2015; n = 239,672) cohorts. Main outcome measures: Model performance. COD was categorized as CV or non-CV with ICD-10 codes as the gold standard. We developed a logistic regression model that uses routinely collected healthcare administrative to categorize CV versus non-CV COD. We assessed model discrimination and calibration in the validation cohort. Results: The strongest predictors for CV COD were history of stroke, history of myocardial infarction, history of heart failure, and CV hospitalization one month before death. In the validation cohort, the c-statistic was 0.80, the sensitivity 0.75 (95 % CI 0.74 to 0.75) and the specificity 0.71 (95 % CI 0.70 to 0.71). In the primary prevention validation sub-cohort, the c-statistic was 0.81, the sensitivity 0.71 (95 % CI 0.70 to 0.71) and the specificity 0.75 (95 % CI 0.75 to 0.75) while in the secondary prevention sub-cohort the c-statistic was 0.74, the sensitivity 0.81 (95 % CI 0.81 to 0.82) and the specificity 0.54 (95 % CI 0.53 to 0.54). Conclusion: Modelling approaches using health administrative data show potential in categorizing CV COD, though further work is necessary before this approach is employed in clinical studies.
