Medicare Advantage in rural areas: implications for hospital sustainability.
This study examined the association between Medicare Advantage penetration levels in rural areas and hospital financial distress and closure. This retrospective study followed rural general acute hospitals open from 2008-2019 or until closure using HCUP State Inpatient Databases for 14 states. Medicare Advantage penetration at rural hospitals grew from 6.5% in 2008 to 20.6% in 2019. A 1-percentage point increase in hospital penetration was associated with an increase in financial stability of 0.04 units on the Altman Z score and a 4% reduction in risk of closure (HR, 0.96).

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).

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.

Hospital proximity and emergency department use among assisted living residents.
The purpose of this retrospective cohort study was to explore the association between the distance of assisted living (AL) communities to the nearest hospital and AL residents' rates of emergency department (ED) utilization. The researchers hypothesized that when access to an ED is a shorter distance, AL-to-ED transfers are more common, especially for non-emergency conditions. The study found that among 540,944 resident-years from 16,514 AL communities, the median distance to the closest hospital was 2.5 miles. After statistical adjustment, a doubling of distance to the closest hospital was related with 43.5 fewer ED treat-and-release visits per 1000 resident years and no significant difference in the rate of ED visits resulting in an inpatient admission. Among ED treat-and-release visits, a doubling of distance was related with a 3.0% decrease in visits classified as nonemergent, and a 1.6% decrease in visits classified as emergent, not primary care treatable.

Surgical procedures at critical access hospitals within hospital networks.
Critical access hospitals provide vital care to more than 80 million Americans. These facilities, often rural, are located greater than 35 miles away from another hospital and are required to maintain patient transfer agreements with other facilities capable of providing higher levels of care. The purpose of this cross-sectional retrospective study was to assess surgical outcomes and expenditures at critical access hospitals that do participate in a hospital network compared with those who do not participate in a hospital network among Medicare beneficiaries. From 2014 to 2018 the researchers compared 16,128 Medicare beneficiary admissions for appendectomy, cholecystectomy, colectomy, or hernia repair at critical access hospitals. The study found that Medicare beneficiaries who received care at critical access hospitals in a hospital network were more likely to carry 2 or more Elixhauser comorbidities. Rates of 30-day mortality and readmission rates were higher at critical access hospitals in a hospital network. Finally, total payments per episode were discovered to be $960 greater per patient at critical access hospitals that were in a hospital network ($23,878) when compared with critical access hospitals that were not in a hospital network ($22,918).

Senior services in US hospitals and readmission risk or mortality among Medicare beneficiaries since the Affordable Care Act.
This study examined whether there was an association between readmission risk or mortality among Medicare beneficiaries and passage of the Affordable Care Act. The study updated the Senior Care Services Scale (SCSS) which describes hospital provision of older adult services before the passage of the Affordable Care Act. The authors conducted a retrospective cohort analysis of older adults ≥65 years (n = 1,416,669), admitted to 2570 US acute-care hospitals from 2014 to 2015. Outcomes were hospital readmission, or death, within 30 and 90 days of discharge. The updated SCSS included three service groups: Inpatient Specialty Care, Post-Acute Community Care, and Home Care and Hospice. Older adults admitted to high Inpatient-Specialty-Care-scoring hospitals had lower risk of death within 30 days, and 90 days. There was no significant association between the other two groups and study outcomes.

Medicare beneficiaries' perspectives on the quality of hospital care and their implications for value-based payment.
The objective of this study was to estimate the relative importance of the 4 quality domains in the Medicare's Hospital Value-Based Purchasing (HVBP) program from the perspective of Medicare beneficiaries and the impact of using beneficiary value weights on incentive payments for hospitals enrolled in FY 2019. A nationally representative sample of 1025 Medicare beneficiaries was recruited through Ipsos KnowledgePanel for an online survey. Hospital performance on clinical outcomes was most highly valued by beneficiaries, followed by safety, patient experience, and efficiency. The authors concluded that current HVBP program value weights do not reflect beneficiary preferences, suggesting that the use of beneficiary value weights may exacerbate disparities by rewarding larger, high-volume hospitals.
