Objectives: The Society of Obstetricians and Gynaecologists of Canada (SOGC) recommends the use of an ultrasound performed between 7 and 14 weeks gestation to accurately predict gestational age (GA). This study aimed to assess the accuracy of earlier ultrasounds (5 to 6 weeks gestation) by comparing the estimated delivery dates (EDD) in participants that had undergone both an earlier ultrasound and ultrasound completed during the standard of care timeframe.
Methods: EDD based on crown-rump length were retrospectively reviewed for patients that had undergone an ultrasound between 5-6 weeks GA versus the recommended 7-14 weeks GA at the Montfort Hospital during 2018 and 2019.
Background: Choosing Wisely Canada is an initiative to reduce overprescribing and overtesting. This study assessed adherence to 4 Choosing Wisely Canada recommendations for interventions commonly performed in primary care: (a) antibiotic prescriptions for infections that are probably viral in origin, (b) routine vitamin D tests in low-risk adults, (c) annual screening blood tests and (d) prescriptions of antipsychotic medication to treat symptoms of dementia.
Methods: We conducted a retrospective cohort study of data from the electronic medical records of patients who had an encounter between 2014 and 2016 with a participating Manitoba Primary Care Research Network primary care provider in Manitoba, Canada.
