This research aims to investigate the implications of COVID-19 on cancer management and clinical outcomes for patients with prostate and colorectal cancer in Canada.

Methods: We examined hospital cancer screening, diagnosis, treatment, length of stay, and mortality data among prostate and colorectal cancer patients between April 2017 and March 2021.

Persistence and switching patterns of migraine prophylactic medications in Canada: A retrospective claims analysis comparing adherence and evaluating the economic burden of illness.

Purpose: To describe patient characteristics, treatment patterns, and the burden of illness among adult migraine patients in Canada prescribed migraine prophylactics. Little is known about the relative persistence of treatments in the real-world setting and the impact of migraine prophylactic therapy on patients. As a result, migraine care in Canada continues to inadequately serve patients suffering from frequent headache days, reflecting a large unmet need.
