Kelly MP, et al. - Authors sought to compare the satisfaction between inpatients and outpatients undergoing hip or knee arthroplasty. They administered portions of the Health Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, the Friends and Family Test and 8 additional questions to 174 consecutive patients. Findings suggested a high level of satisfaction in both the groups, but differences when present favored outpatient surgery in the ambulatory surgery center (ASC). Compared to outpatients, inpatients were older, heavier and had higher Charlson comorbidity scores.
