Association of health professional shortage area hospital designation with surgical outcomes and expenditures among Medicare beneficiaries.
This study’s objective was to compare surgical outcomes and expenditures at hospitals located in Health Professional Shortage Areas to nonshortage area designated hospitals among Medicare beneficiaries. This cross-sectional retrospective study used data from 842,787 Medicare beneficiary patient admissions to hospitals with and without Health Professional Shortage Area designations for common operations including appendectomy, cholecystectomy, colectomy, and hernia repair from 2014 to 2018. Primary outcomes measures were 30-day mortality, hospital readmissions, and 30-day surgical episode payments. Patients (mean age=75.6 years, males=44.4%) undergoing common surgical procedures in shortage area hospitals were less likely to be White (84.6% vs 88.4%) and less likely to have≥2 Elixhauser comorbidities (75.5% vs 78.2%). Patients undergoing surgery at Health Professional Shortage Area hospitals had lower risk-adjusted rates of 30-day mortality (6.05% vs 6.69%) and readmission (14.99% vs 15.74%). Medicare expenditures at Health Professional Shortage Area hospitals were also lower than nonshortage designated hospitals ($28,517 vs $29,685).

Outcomes for high-risk surgical procedures across high- and low-competition hospital markets.
The purpose of this retrospective study was to assess whether there is a relationship between hospital market competition and outcomes post high-risk surgery. The study included Medicare beneficiaries 65 years and older who electively underwent 1 of 10 high-risk surgical procedures. Procedures included: bariatric surgery, carotid endarterectomy, esophagectomy hip replacement, knee replacement, mitral lung resection valve repair, open aortic aneurysm repair, pancreatectomy, and rectal resection. Hospitals were categorized into high-competition and low-competition markets based on the hospital market Herfindahl-Hirschman index. The primary outcome was 30-day postoperative mortality and readmissions. The study found that when analyzed by procedure, compared with low-competition hospitals, high-competition market hospitals demonstrated higher 30-day mortality for 2 of 10 procedures (mitral valve repair and carotid endarterectomy) and no difference for 5 of 10 procedures (open aortic aneurysm repair, bariatric surgery, esophagectomy, knee replacement, and hip replacement.) High-competition hospitals also demonstrated 30-day readmissions that were higher for 5 of 10 procedures (carotid endarterectomy, knee replacement, mitral valve repair, open aortic aneurysm repair, and rectal resection) and no difference for 3 procedures (bariatric surgery, esophagectomy: and pancreatectomy.) Hospitals in high-competition compared with low-competition markets cared for patients who were older, were more likely to be racial and ethnic minority individuals and had more comorbidities.

High-risk surgery among Medicare beneficiaries living in health professional shortage areas.
This study’s objective was to compare high-risk surgical outcomes at hospitals located in Health Professional Shortage Areas to nonshortage area designated hospitals among Medicare beneficiaries. The authors performed a retrospective review of Medicare beneficiaries living in health professional shortage areas and nonshortage areas who underwent abdominal aortic aneurysm repair, coronary artery bypass graft, esophagectomy, liver resection, pancreatectomy, or rectal resection between 2014 and 2018. They compared rates of postoperative complications and 30-day mortality between the patient cohorts. They used beneficiary and hospital ZIP codes to quantify travel time to obtain care. Compared with patients living in nonshortage areas, patients living in health professional shortage areas traveled longer (median 60.0 vs 28.0 minutes). There were no differences in risk-adjusted rates of complications (28.5% vs 28.6%) and small differences in rates of 30-day mortality (4.2% vs 4.4%) between beneficiaries living in shortage areas versus those not in shortage areas, respectively.

Changes in surgical outcomes in a Statewide Quality Improvement Collaborative with introduction of simultaneous, comprehensive interventions.
Researchers investigated whether a comprehensive quality improvement program implemented simultaneously across hospitals at the formation of a quality improvement collaborative (QIC) would improve patient outcomes. They analyzed risk-adjusted rates of postoperative morbidity and mortality for patients who had undergone surgery at hospitals in the Illinois Surgical Quality Improvement Collaborative (ISQIC); analyses compared ISQIC hospitals with hospitals in the NSQIP Participant Use File (PUF). Although complication rates decreased at both ISQIC and PUF hospitals, findings showed that participation in ISQIC was associated with a significantly greater improvement in death or serious morbidity. The researchers concluded that these results emphasize the potential of QICs to improve patient outcomes.

Evaluation of initial participation in public reporting of American College of Surgeons NSQIP surgical outcomes on Medicare's Hospital Compare website.
The objective of this paper was to compare CMS-National Surgical Quality Improvement Program (CMS-NSQIP) participating hospitals with American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) hospitals that elected not to participate in Hospital Compare. The researchers found few measurable differences between CMS-NSQIP participating and nonparticipating hospitals.
