A new report shows that the difference between expected and observed mortality rates for hospitalized surgical patients continues to improve. Hospitals have achieved nearly a 20% increase in survival rates for these patients compared with expected, reflecting advances in evidence-based care and safety practices. However, the analysis, from Vizient and the American Hospital Association, also finds that the average length of stay has risen by almost a full day over the past five years, due to increasing patient acuity and insurer-related delays in post-acute care placement, particularly in Medicare Advantage plans. This trend suggests ongoing challenges in balancing improved patient outcomes with efficient hospital throughput.
