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).

Organization of cancer specialists in US physician practices and health systems.
This study’s objective was to describe the supply of cancer specialists, the organization of cancer care within versus outside of health systems, and the distance to multispecialty cancer centers. The authors used the 2018 Health Systems and Provider Database from the National Bureau of Economic Research and 2018 Medicare data to identify 46,341 unique physicians providing cancer care. They stratified physicians by discipline (adult/pediatric medical oncologists, radiation oncologists, surgical/gynecologic oncologists, other surgeons performing cancer surgeries, or palliative care physicians), system type (National Cancer Institute [NCI] Cancer Center system, non-NCI academic system, nonacademic system, or nonsystem/independent practice), practice size, and composition (single disciplinary oncology, multidisciplinary oncology, or multispecialty). They computed the density of cancer specialists by county and calculated distances to the nearest NCI Cancer Center. Results found that more than half of all cancer specialists (57.8%) practiced in health systems, but 55.0% of cancer-related visits occurred in independent practices. A majority of system-based physicians were in large practices with more than 100 physicians, while those in independent practices were in smaller practices. Breakdown by specialty type showed that practices in NCI Cancer Center systems (95.2%), non-NCI academic systems (95.0%), and nonacademic systems (94.3%) were primarily multispecialty, while fewer independent practices (44.8%) were. Many rural areas had sparse cancer specialty density, where the median travel distance to an NCI Cancer Center was 98.7 miles. Higher-income areas had shorter distances to NCI Cancer centers than low-income areas, even for individuals in suburban and rural areas.

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.

Using time series clustering to segment and infer emergency department nursing shifts from electronic health record log files.
Clinical shifts are an essential unit of work recognized in clinical settings and may function as a primary unit of analysis in the study of documentation burden. The purpose of this proof- of-concept study was to investigate the feasibility of a new approach utilizing time series clustering to segment and infer clinician shifts from electronic health record (HER) log files. The researchers recorded 33,535,585 events between April-June 2021 and computationally identified 43,911 potential shifts among 2,285 emergency department nurses. On average, shifts were 10.6±3.1 hours in duration. Researchers classified the shifts based on type: day, evening, night; and length: 12-hour, 8-hour, other. The preliminary results of the study found that unsupervised clustering methods may be a feasible approach for quickly identifying clinician shifts.

A repeated cross-sectional study of nurses immediately before and during the COVID-19 pandemic: Implications for action
The goal of this cross-sectional study was to establish whether hospital nursing care shortages are primarily due to the COVID pandemic, and therefore likely to subside, or if shortages are due to understaffing and poor working conditions that predated the pandemic. The study considered registered nurses in New York and Illinois, and a subset of staff nurses employed in 357 hospitals, before and during the pandemic. While no evidence was found to show that large numbers of nurses left in the first 18 months of the pandemic, the study’s findings indicate that nurses in hospitals with better staffing and more favorable work environments prior to the pandemic reported significantly better outcomes. The authors concluded that policies that prevent chronic understaffing have the most potential to stabilize the hospital nurse workforce.
