Project #66:
Changes in PINCER indicators throughout the COVID-19 pandemic


PINCER is a pharmacist-led information technology intervention that aims to reduce the risk of patient harm due to medication errors as captured by 13 indicators of hazardous prescribing or delayed medication monitoring. The COVID-19 pandemic has been shown to have caused significant disruption to healthcare services. This study examines the rate of hazardous prescribing or delayed monitoring as indicated by each individual PINCER indicator between September 2019 and September 2021 to assess the impact of the pandemic.
