Abstract
Background  There is little research on the impact of medical education on patient outcome. We studied whether teaching capability is associated with altered short‐term patient outcomes. Methods  We performed a multicentre retrospective cross‐sectional study involving 40 clinician teachers who had attended on the general internal medicine services in hospitals affiliated with the University of Toronto along with the clinical outcomes of consecutive patients treated for community‐acquired pneumonia, congestive heart failure, chronic obstructive pulmonary disease and gastrointestinal bleeding ( n = 4377) between 1999 and 2001. Doctors were characterised by teaching effectiveness scores ( n = 677) as high‐rated or low‐rated according to house staff ratings. Results  There was no correlation between the teaching effectiveness scores and the mean length of stay for those patients treated for community‐acquired pneumonia (high‐rated = 10.3 versus low‐rated = 8.1 days, P = 0.058), congestive heart failure (high‐rated = 10.1 versus low‐rated = 9.9 days, P = 0.978), chronic obstructive pulmonary disease (high‐rated = 9.4 versus low‐rated = 9.9 days, P = 0.419) and gastrointestinal bleeding (high‐rated = 6.3 versus low‐rated = 6.8 days, P = 0.741). In addition, we observed no significant correlation between teaching effectiveness scores and 7‐day, 28‐day and 1‐year readmission rates for all pre‐specified diagnoses. Conclusion  There is no large correlation between teaching effectiveness scores and short‐term patient outcomes, suggesting that doctor teaching capabilities, as perceived by house staff, does not generally impact clinical care.
