Chou YY, et al. - Researchers analyzed data of a total of 6,367 patients identified through Taiwan’s National Health Insurance Research Database to identify the optimal hospital and surgeon volume thresholds to reduce readmission, costs, and length of stay (LOS) for total hip replacement (THR). In addition, they ascertained the effects of these volume thresholds on 30-day unplanned readmission, costs, and LOS for THR. For the first time, the surgeon volume threshold was identified that can reduce 30-day unplanned readmission rates, costs and LOS for THR. For hospitals and surgeons, the volume thresholds were 65 cases and 15 cases a year, respectively. They noted higher 30-day unplanned readmission rates, costs and LOS for patients who received THR from surgeons who did not reach the volume threshold compared to those who received THR from surgeons who reached the volume threshold.
