March 2014The Nature of Surgeon Human Capital Depreciation
with Lorens A. Helmchen: w20017
To test how practice interruptions affect worker productivity, we estimate how temporal breaks affect surgeons’ performance of coronary artery bypass grafting (CABG). Using a sample of 188 surgeons who performed 56,315 CABG procedures in Pennsylvania between 2006 and 2010, we find that a surgeon’s additional day away from the operating room raised patients’ inpatient mortality risk by up to 0.067 percentage points (2.4% relative effect) but reduced total hospitalization costs by up to 0.59 percentage points. In analyses of 93 high-volume surgeons treating 9,853 patients admitted via an emergency department, where temporal distance effects are most plausibly exogenous, an additional day away raised mortality risk by 0.398 percentage points (11.4% relative effect) but reduced cost by up to ...
July 2010Do Bad Report Cards Have Consequences? Impacts of Publicly Reported Provider Quality Information on the CABG Market in Pennsylvania
with Justin Wang, Shin-Yi Chou, Muzhe Yang: w16225
Since 1992, the Pennsylvania Health Care Cost Containment Council (PHC4) has published cardiac care report cards for coronary artery bypass graft (CABG) surgery providers. We examine the impact of CABG report cards on a provider's aggregate volume and volume by patient severity and then employ a mixed logit model to investigate the matching between patients and providers. We find a reduction in volume of poor performing and unrated surgeons' volume but no effect on more highly rated surgeons or hospitals of any rating. We also find that the probability that patients, regardless of severity of illness, receive CABG surgery from low-performing surgeons is significantly lower.
