Objective
To determine the relationship between postoperative morbidity and mortality and patients' perspectives of care.
Summary Background Data
Priorities in healthcare quality research are shifting to place greater emphasis on patient-centered outcomes. Whether patients' perspectives of care correlate with surgical outcomes remains unclear.
Methods
Using data from the Michigan Surgical Quality Collaborative clinical registry (2008–2012), we identified 41,833 patients undergoing major elective general or vascular surgery. Our exposure variables were the HCAHPS Total and Base Scores derived from the Hospital Value-Based Purchasing (VBP) Patient Experience of Care Domain. Using multilevel mixed-effects logistic regression models, we adjusted hospitals' rates of morbidity and mortality for patient comorbidities and case mix. We stratified reporting of outcomes by quintiles of hospitals' Total and Base Scores.
Results
Risk-adjusted morbidity (13.6% to 28.6%) varied widely across hospitals. There were no significant differences in risk-adjusted morbidity rates between hospitals with the lowest versus highest HCAHPS Total Score (24.5% vs. 20.2%, p=0.312). The HCAHPS Base Score, which quantifies sustained achievement or improvement in patients' perspectives of care, was not associated with a reduction in postoperative morbidity over the study period despite an overall decrease of 2.5% for all centers. We observed a similar relationship between HCAHPS Total and Base Scores and postoperative mortality.
Conclusions and Relevance
Patients' perspectives of care do not correlate with the incidence of morbidity and mortality following major surgery. Improving patients' perspectives and objective outcomes may require separate initiatives for surgeons in Michigan.
