ASK US series: Ethical design, data integrity and consent for cluster randomized trials


6 April 2023


12:00 - 12:45 p.m.


Virtual event

Question: What should research teams know about consent requirements/expectations around collecting data for cluster randomized trials? 


Cluster randomized trials (CRTs) are becoming more popular in community-based intervention studies, public health research and quality improvement research. CRTs typically compare clusters of social units, such as hospital wards, clinics, neighborhoods and communities. Nevertheless, they also raise challenges for the consent process and collecting, using and sharing of study data. This session will be of interest to anyone who may be asked to obtain consent, collect data or is responsible for oversight, quality or ethics review for CRTs. 


Join our special guest Dr. Anita Ho in the third episode of our ASK US series, season three. Learn more about why we conduct CRTs, ethical consent and data collection methods, and other considerations for study design.
