Background. Over the decade of the 1990s, hospital stay after operation declined in response to prospective payment and managed care. As a result, complications previously detected and treated in the hospital may have begun to occur after discharge. In addition, discharge to nursing homes and rehabilitation hospitals may have increased. To address these questions, we used a statewide database to look at the use of postacute care and the 30-day readmission and mortality after coronary bypass operation. Methods. A modification of the Commonwealth of Massachusetts Division of Health Care Finance and Policy discharge data to include a unique patient identifier allowed us to retrospectively track patient destination at discharge and study 30-day readmission to all hospitals in the state. Results. Over the 3-year period after the institution of the unique patient identifier (1993 to 1996), postoperative length of stay after coronary bypass operation decreased from 7.4 to 6 days (19%, P < .0005), but the 30-day readmission rate (17.7%) did not increase. Discharge to rehabilitation hospitals and skilled nursing facilities rose significantly (11.7% to 23.8%), especially in the Medicare population (17.2% to 38.5%). Mortality in the 30 days after discharge remained constant at 0.3%. Conclusions. A shorter postoperative length of stay did not appear to disadvantage coronary artery bypass patients by increasing their likelihood of readmission or death. Cost savings from reduced length of stay were offset by increased use of postacute services.
