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 characteristics associated with nurse staffing during labor and birth: Inequities for the most vulnerable maternity patients.
The objective of this study was to estimate the relationship between hospital characteristics and adherence with Association of Women's Health, Obstetric and Neonatal Nurses nurse staffing guidelines. Registered nurses were enrolled in a cross-sectional survey; hospital characteristics were obtained from the 2018 American Hospital Association Annual Survey. The findings indicated that, overall, nurses reported strong adherence to staffing guidelines within their hospitals. Higher birth volume, teaching status, higher percentage of Medicaid-paid births, and presence of a neonatal intensive care unit were all associated with lower mean adherence scores.

Hospital-cardiologist integration often occurs without a practice acquisition.
This study’s objective was to determine how much of the increase in hospital-cardiologist integration comes from acquisition of physician practices compared to individual employment decisions. Data from 2011 to 2018 was used from the American Medical Association Masterfile and Medicare. In 2011 18% of cardiologists were integrated, which rose to 25% in 2016. It was found that 48% of integrations occurred without acquisitions and that physicians who had completed residencies in the past 5 years had higher rates of integration that increased over time. Rates of early career physicians joining hospital systems also rose from 25% to 32% during that time period.

Hospital nurse staffing and sepsis protocol compliance and outcomes among patients with sepsis in the USA: a multistate cross-sectional analysis.
The timely and effective administration of sepsis treatment may improve sepsis outcomes, and those improvements may provide evidence of the need for mandated reporting of adherence to sepsis care protocol. The purpose of the study was to better understand the association between patient-to-nurse staffing ratios, sepsis protocol compliance, and patient outcomes. The researchers conducted a cross-sectional study utilizing linked data from 537 hospitals from across California, Florida, Illinois, Pennsylvania, New Jersey, and New York (representing 252,699 Medicare inpatients with sepsis present on admission), nurse and hospital surveys, and Centers for Medicare and Medicaid Services Hospital Compare and the corresponding MedPAR patient claims. The study found that every additional patient per nurse was associated with greater odds of mortality, readmission, ICU admission, and greater risk of relative duration of stay. Every 10% increase in compliance of sepsis protocol was only associated with a shorter duration of stay. The study concluded that improvements in nurse staffing and the nurse-to-patient ratios had a greater impact on sepsis infection outcomes than compliance with protocols.

Relationship between rural hospital closures and the supply of nurse practitioners and certified registered nurse anesthetists.
This study sought to examine the extent to which rural hospital closures are associated with changes in the NP (nurse practitioner) and CRNA (certified registered nurse anesthetist) workforce. The authors used the Area Health Resources Files (AHRF) data from 2010-2017 to estimate the relationship between rural hospital closures and changes in the supply of NPs and CRNAs. They found 151 hospital closures among 1,544 rural counties. After controlling for local market characteristics, they did not find a significant relationship between hospital closure and the supply of NPs and CRNAs.

Gaps in emergency general surgery coverage in the United States.
Researchers sought to measure gaps in round-the-clock emergency general surgery (EGS) care via a survey of all US adult acute care general hospitals with an emergency room, at least 1 operating room. They found that 17.1% of hospitals responding were unable to always provide round-the-clock EGS care. Rural location, smaller bed size, and non-teaching status were associated with lack of round-the-clock care. Inconsistent surgeon coverage was the primary reason for this lack. However, lack of a tiered system for booking emergency cases, no anesthesia availability overnight, and no stipend for EGS call were also associated with the inability to provide round-the-clock EGS care.

The surgical and anesthesia workforce and provision of surgical services in rural communities: a mixed-methods examination.
This mixed-methods study described the distribution of the surgical and anesthesia workforce and qualitatively explored how such workforce and other factors influenced rural hospitals' provision of surgical services. Using American Hospital Association survey data, the researchers found that within rural counties, 55.1% had no surgeon, 81.2% had no anesthesiologist, and 58.1% had no Certified Registered Nurse Anesthetist. While rural hospitals reported meeting community needs for elective and noncomplex surgeries, these hospitals continued to face significant challenges providing subspecialty surgeries, emergency surgeries, and 24-hour obstetrical services.

Hiring practices of US academic surgery departments-challenges and opportunities for more inclusive hiring.
To increase workforce diversity among academic medical centers, the Association of American Medical Colleges recommends multiple inclusive strategies for evaluating and hiring candidates. The objective of this study was to determine (1) usual and inclusive hiring practices used among academic surgery departments and (2) the barriers to utilization of inclusive hiring practices. The investigators concluded that many chairs rely heavily on internal hires or trusted networks, which may limit both demographic and cognitive diversity.

Staffing trends in magnet and non-magnet hospitals after state legislation.
This study examined whether there was a difference in staffing of registered nurses in Magnet and non-Magnet hospitals using unit-level, publicly available data in New Jersey. This secondary analysis of longitudinal RN staffing data was conducted using 64 hospitals representing 12 nursing specialties during the time span of 2008 to 2015. There was a slight increase in staffing at Magnet hospitals compared to non-Magnet hospitals, but RN staffing improved in all hospitals. No meaningful difference in staffing for all 12 specialties was found.

When rural hospitals close, the physician workforce goes.
Researchers examined the relationship between rural hospital closures and the supply of physicians across different specialties in the years leading up to and after a closure. They observed significant annual reductions in the supply of general surgeons in the years leading up to a closure. They also found that rural hospital closures were associated with immediate and persistent decreases in the supply of surgical specialists and long-term decreases in the supply of physicians across multiple specialties. Because this decrease could lead to reduced access to care for rural residents, they recommended that future policy efforts focus on supporting and maintaining health care delivery models that do not depend on hospitals.

Nurse Outcomes in Magnet(R) and non-magnet hospitals.
The goal of this study was to determine whether work environments, staffing, and nurse outcomes differ between Magnet and non-Magnet hospitals. Results demonstrated superior nurse work environments in Magnet hospitals compared with non-Magnet hospitals, with better work environments being associated with lower nurse job dissatisfaction and burnout. Three decades of evidence showing superior outcomes for Magnet hospitals place this organizational innovation into a class all of its own as best practice, deserving the attention of hospital leaders, nurses, and the public.

Association between hospital staffing models and failure to rescue.
The purpose of this study was to identify hospital staffing models associated with failure to rescue (FTR) rates at low- and high-performing hospitals. The investigators concluded that low FTR hospitals had significantly more staffing resources than high FTR hospitals. They indicated that although hiring additional staff may be beneficial, there remain significant financial limitations for many hospitals to implement robust staffing models.

Effects of public reporting legislation of nurse staffing: a trend analysis.
The authors examined nurse staffing trends after the New Jersey enactment of P.L.1971, c.136 (C.26:2 H-13) on January 24, 2005, mandating that all health care facilities compile, post, and report staffing information. They found that the number of patients per registered nurse decreased for ten specialties, and conclude that this indicates the importance of public reporting in improving patient safety.

The current State of the acute care surgery workforce: a boots on the ground perspective.
Acute care surgery (ACS) was proposed to address a general surgery workforce crisis; however, the ACS workforce composition is unknown. A national survey was conducted to determine the differences in the emergency general surgery (EGS) workforce between ACS and non-ACS hospitals. The investigators concluded that ACS and non-ACS hospitals differ in their surgical workforce. It is clear that ACS hospitals have more human capital, which suggests that ACS hospitals may require more dedicated resources compared to non-ACS hospitals.

Changes in hospital-physician affiliations in U.S. hospitals and their effect on quality of care.
This study examined changes in U.S. acute care hospitals that reported employment relationships with their physicians and to determine whether quality of care improved after the hospitals switched to this integration model. It concluded that during the past decade, hospitals have increasingly become employers of physicians. The study's findings suggest that physician employment alone probably is not a sufficient tool for improving hospital care.
