Although several global health and accreditation authorities encourage quality improvement as a competency in medical education programmes, literature tackling quality improvement education in undergraduate medical education is scarce. This study aims to assess the knowledge and attitude of medical students at Beirut Arab University towards quality improvement, using the BASIC-QI tool. The intervention consisted of a five-hour workshop including theoretical and hands-on parts. Students completed the survey just before, immediately after, and one month following the workshop. This longitudinal time-series quasi-experimental study targeted all fifth-year medical students at Beirut Arab University throughout the academic year 2020-2021, each group during their family medicine rotation. Fifty-five out of 77 students completed the survey at all three stages. The mean scores of each of the "Attitude and Beliefs Scale", and the "Knowledge of QI Scale" both showed a significant increase right after and one month after the session. Thus, given the favourable results of this study, we advocate that quality improvement workshops be included in the curriculum of medical schools and health professions faculties, and in such an interactive and hands-on format.
