Importance: Treating surgical complications presents a major challenge for hospitals striving to deliver high-quality care while reducing costs. Costs associated with rescuing patients from perioperative complications are poorly characterized. Objective: To evaluate differences across hospitals in the costs of care for patients surviving perioperative complications after major inpatient surgery. Design, Setting, and Participants: Retrospective cohort study using claims data from the Medicare Provider Analysis and Review files...

OBJECTIVE: To evaluate the extent to which patient-reported outcomes (PROs) (eg, health-related quality of life) are distinct from clinical outcomes following bariatric surgery. BACKGROUND: Hospital quality measurement often focuses on traditional clinical outcomes (eg, complications). However, PROs may provide a unique perspective regarding performance, particularly for common, low-risk procedures. METHODS: We used data from 11,420 patients who underwent bariatric surgery (2008-2012) from the Michigan Bariatric Surgery Collaborative (39 hospitals)...

OBJECTIVE: To examine the relationship between hospital outcomes and expenditures in patients undergoing bariatric surgery in the United States. BACKGROUND: As one of the most common surgical procedures in the United States, bariatric surgery is a major focus of policy reforms aimed at reducing surgical costs. These policy mechanisms have made it imperative to understand the potential cost savings of quality-improvement initiatives. METHODS: We performed a retrospective review of 38,374 Medicare beneficiaries undergoing bariatric surgery between 2011 and 2013...

BACKGROUND: Recent data establish a strong link between peer video ratings of surgical skill and clinical outcomes with laparoscopic gastric bypass. Whether skill for one bariatric procedure can predict outcomes for another related procedure is unknown. METHODS: Twenty surgeons voluntarily submitted videos of a standard laparoscopic gastric bypass procedure, which was blindly rated by 10 or more peers using a modified version of the Objective Structured Assessment of Technical Skills...

BACKGROUND: Laparoscopic sleeve gastrectomy has surpassed gastric bypass and laparoscopic adjustable gastric banding recently as the most common weight-loss procedure. Previously, substantial concerns existed regarding variation in perioperative safety with bariatric surgery. This study aimed to assess rates of perioperative complications for laparoscopic sleeve gastrectomy across hospitals and in relation to procedure volume within the Michigan Bariatric Surgery Collaborative. STUDY DESIGN: We analyzed 8,693 patients who underwent laparoscopic sleeve gastrectomy from 2013 through 2014 across 40 hospitals in the Michigan Bariatric Surgery Collaborative...

OBJECTIVE: To determine the effect of hospital characteristics on failure to rescue after high-risk surgery in Medicare beneficiaries. SUMMARY BACKGROUND DATA: Reducing failure to rescue events is a common quality target for US hospitals. Little is known about which hospital characteristics influence this phenomenon and more importantly by how much. METHODS: We identified 1,945,802 Medicare beneficiaries undergoing 1 of six high-risk general or vascular operations between 2007 and 2010...

BACKGROUND: A large body of research suggests that hospitals with intensive care units staffed by board-certified intensivists have lower mortality rates than those that do not. OBJECTIVE: To determine whether hospitals can reduce their mortality by adopting an intensivist staffing model. DESIGN: Retrospective, longitudinal study using 2003-2010 Medicare data and the Leapfrog Group Hospital surveys. SETTING AND PATIENTS: In total, 2,916,801 Medicare patients at 488 US hospitals...

BACKGROUND: Although there is growing interest in applying patient-reported outcomes (PROs) toward surgical quality, the extent to which PROs vary across hospitals following surgical procedures is unknown. OBJECTIVES: We examined variation in PROs, specifically health-related quality of life (HRQOL), across hospitals performing bariatric surgery. RESEARCH DESIGN: A retrospective cohort study. SUBJECTS: The Michigan Bariatric Surgery Collaborative is a statewide consortium of 39 hospitals performing laparoscopic gastric bypass, gastric banding, or sleeve gastrectomy (n=11,420 patients between 2008 and 2012)...

Hospital executives pursue external recognition to improve market share and demonstrate institutional commitment to quality of care. The Magnet Recognition Program of the American Nurses Credentialing Center identifies hospitals that epitomize nursing excellence, but it is not clear that receiving Magnet recognition improves patient outcomes. Using Medicare data on patients hospitalized for coronary artery bypass graft surgery, colectomy, or lower extremity bypass in 1998-2010, we compared rates of risk-adjusted thirty-day mortality and failure to rescue (death after a postoperative complication) between Magnet and non-Magnet hospitals matched on hospital characteristics...

IMPORTANCE: Hospitals' care intensity varies widely across the United States. Payers and policy makers have become focused on promoting quality, low-cost, efficient health care. OBJECTIVE: To evaluate whether increased hospital care intensity (HCI) is associated with improved outcomes following major surgery. DESIGN, SETTING, AND PARTICIPANTS: Using national Medicare data in this retrospective cohort study, we identified 706,520 patients at 2544 hospitals who underwent 1 of 7 major cardiovascular, orthopedic, or general surgical operations...

OBJECTIVES: To determine if mortality varies by time-to-readmission (TTR). BACKGROUND: Although readmissions reduction is a national health care priority, little progress has been made toward understanding why only some readmissions lead to adverse outcomes. METHODS: In this retrospective cross-sectional cohort analysis, we used 2005-2009 Medicare data on beneficiaries undergoing colectomy, lung resection, or coronary artery bypass grafting (n = 1,033,255) to created 5 TTR groups: no 30-day readmission (n = 897,510), less than 6 days (n = 44,361), 6 to 10 days (n = 31,018), 11 to 15 days (n = 20,797), 16 to 20 days (n = 15,483), or more than 21 days (n = 24,086)...

BACKGROUND: Since October of 2012, Medicare's Hospital Readmissions Reduction Program has fined 2,200 hospitals a total of $500 million. Although the program penalizes readmission to any hospital, many institutions can only track readmissions to their own hospitals. We sought to determine the extent to which same-hospital readmission rates can be used to estimate all-hospital readmission rates after major surgery. STUDY DESIGN: We evaluated 3,940 hospitals treating 741,656 Medicare fee-for-service beneficiaries undergoing CABG, hip fracture repair, or colectomy between 2006 and 2008...

BACKGROUND: Perioperative mortality in the elderly is high after emergency surgery and varies considerably among hospitals-an observation partially explained by differences in failure to rescue. We hypothesize that failure to rescue after certain types of complications underlies the disproportionately poor outcomes observed in elderly patients. STUDY DESIGN: We identified 23,217 patients undergoing emergent general or vascular surgery procedures at 41 hospitals within the Michigan Surgical Quality Collaborative between 2007 and 2012...
