RT Journal Article SR Electronic T1 Understanding challenges of using routinely collected health data to address clinical care gaps: a case study in Alberta, Canada JF BMJ Open Quality JO BMJ Open Qual FD British Medical Journal Publishing Group SP e001491 DO 10.1136/bmjoq-2021-001491 VO 11 IS 1 A1 Taylor McGuckin A1 Katelynn Crick A1 Tyler W Myroniuk A1 Brock Setchell A1 Roseanne O Yeung A1 Denise Campbell-Scherer YR 2022 UL http://bmjopenquality.bmj.com/content/11/1/e001491.abstract AB High-quality data are fundamental to healthcare research, future applications of artificial intelligence and advancing healthcare delivery and outcomes through a learning health system. Although routinely collected administrative health and electronic medical record data are rich sources of information, they have significant limitations. Through four example projects from the Physician Learning Program in Edmonton, Alberta, Canada, we illustrate barriers to using routinely collected health data to conduct research and engage in clinical quality improvement. These include challenges with data availability for variables of clinical interest, data completeness within a clinical visit, missing and duplicate visits, and variability of data capture systems. We make four recommendations that highlight the need for increased clinical engagement to improve the collection and coding of routinely collected data. Advancing the quality and usability of health systems data will support the continuous quality improvement needed to achieve the quintuple aim.
