<h3>Importance</h3> Off-label use of prescription drugs has been identified as an important contributor to preventable adverse drug events (ADEs) in children. Despite concerns regarding outcomes, date, no systematic investigation the effects off-label adult populations performed. <h3>Objective</h3> To monitor and evaluate its effect on ADEs population. <h3>Design, Setting, Participants</h3> A cohort 46 021 patients who received 151 305 incident prescribed was assembled from primary care...
Objective To examine off-label indications for antidepressants in primary care and determine the level of scientific support prescribing.Design Descriptive study antidepressant prescriptions written by physicians using an indication based electronic prescribing system.Setting Primary practices around two major urban centres Quebec, Canada.Participants Patients aged 18 years or older who visited a physician between 1 January 2003 30 September 2015 were prescribed through system.Main outcome...
<b>Background:</b> In the face of an influenza pandemic, accurate estimates epidemiologic parameters are required to help guide decision-making. We sought estimate for pandemic H1N1 using data from initial reports laboratory-confirmed cases. <b>Methods:</b> obtained on cases reported in province Ontario, Canada, with dates symptom onset between Apr. 13 and June 20, 2009. Incubation periods duration symptoms were estimated fit parametric distributions. used competing-risk models risk hospital...
This pharmacoepidemiology study uses national Canadian electronic medical record data to describe treatment indications for antidepressants and temporal trends in antidepressant prescribing depression Quebec, Canada, from 2006 through 2015.
OBJECTIVES: To estimate the dose‐related risk of injuries in older adults associated with use low‐, medium‐, and high‐potency opioids. DESIGN: Historical population‐based cohort study: 2001 to 2003. SETTING: Quebec, Canada's, universal healthcare system. PARTICIPANTS: Four hundred three thousand thirty‐nine aged 65 older. MEASUREMENTS: Population‐based health databases were used measure preexisting factors for 2001/02 drug during follow‐up (2003). Type dose opioids measured as time‐dependent...
<h3>Background</h3> In 2001, Canada Health Infoway unveiled a plan to implement national system of interoperable electronic health records. This government-funded corporation introduced novel model for interprovincial/territorial collaboration establish core aspects framework. Despite this $1.6 billion initiative, continues lag behind other Western countries in adopting We conducted study identify the success different Canadian and ways improve adoption <h3>Methods</h3> used case approach...
<h3>Background</h3>Off-label prescribing may lead to adverse drug events. Little is known about its prevalence and determinants resulting from challenges in documenting treatment indication.<h3>Methods</h3>We used the Medical Office of XXI Century electronic health record network Quebec, Canada, where documentation indication mandatory. One hundred thirteen primary care physicians wrote 253 347 prescriptions for 50 823 patients January 2005 through December 2009. Each was classified as...
<h3>Background:</h3> Understanding inequalities in SARS-CoV-2 transmission associated with the social determinants of health could help development effective mitigation strategies that are responsive to local dynamics. This study aims quantify geographic concentration cases across 16 census metropolitan areas (hereafter, cities) 4 Canadian provinces, British Columbia, Manitoba, Ontario and Quebec. <h3>Methods:</h3> We used surveillance data on confirmed for at level dissemination area (DA)....
<h3>Background:</h3> During the first year of COVID-19 pandemic, proportion reported cases among Canadians was under 6%. Although high vaccine coverage achieved in Canada by fall 2021, Omicron variant caused unprecedented numbers infections, overwhelming testing capacity and making it difficult to quantify trajectory population immunity. <h3>Methods:</h3> Using a time-series approach data from more than 900 000 samples collected 7 research studies collaborating with Immunity Task Force...
Motor vehicles emit particulate matter < 2.5 microm in diameter (PM(2.5)), and as a result, PM(2.5) concentrations tend to be elevated near busy streets. Studies of the relationship between motor vehicle emissions respiratory health are generally limited by difficulties exposure assessment. We developed refined model implemented it using geographic information system estimate average daily census enumeration area (EA) PM(2.5). Southeast Toronto, study area, includes 334 EAs covers 16 km(2)...
