RESUMO
Importance: Health care administrative overhead is greater in the US than some other nations but has not been assessed in the Veterans Health Administration (VHA). Objective: To compare administrative staffing patterns in the VHA and private (non-VHA) sectors. Design, Setting, and Participants: This cross-sectional study was conducted using US employment data from 2019, prior to pandemic-related disruptions in health care staffing, and was carried out between January 14 and August 10, 2023. A nationally representative sample of federal and nonfederal personnel in hospitals and ambulatory care settings from the American Community Survey (ACS), all employees reported in VHA personnel records, and personnel in health insurance carriers and brokers tabulated by the Bureau of Labor Statistics (BLS) were analyzed. Exposure: VHA vs private sector health care employment, including 397 occupations grouped into 18 categories. Main Outcome and Measure: The proportion of staff working in administrative occupations. Results: Among 3â¯239â¯553 persons surveyed in the ACS, 122â¯315 individuals (weighted population, 12â¯501â¯185 individuals) were civilians working in hospitals or ambulatory care; of the weighted population, 12â¯156â¯988 individuals (mean age, 42.6 years [95% CI, 42.5-42.7 years]; 76.2% [95% CI, 75.9%-76.5%] females) were private sector personnel and 344â¯197 individuals (mean age, 46.2 years [95% CI, 45.7-46.7 years]; 63.8% [95% CI, 61.8%-65.8%] females) were federal employees. In clinical settings, administrative occupations accounted for 23.4% (95% CI, 23.1%-23.8%) of private sector vs 19.8% (95% CI, 18.1%-21.4%) of VHA personnel. After including 1â¯000â¯800 employees at private sector health insurers and brokers and 13â¯956 VHA Central Office personnel with administrative occupations, administration accounted for 3â¯851â¯374 of 13â¯157â¯788 private sector employees (29.3%) vs 77â¯500 of 343â¯721 VHA employees (22.5%). Physicians represented approximately 7% of personnel in the VHA (7.2% [95% CI, 6.1%-8.2%]) and private sector (6.5% [95% CI, 6.3%-6.7%]), while the VHA deployed more registered nurses (23.7% [95% CI, 21.6%-25.8%] vs 21.2% [95% CI, 20.9%-21.5%]) and social service personnel (6.3% [95% CI, 5.4%-7.1%] vs 4.9% [95% CI, 4.7%-5.0%]) than the private sector. Conclusions and Relevance: In this study, administrative occupations accounted for a smaller share of personnel in the VHA compared with private sector care, a difference possibly attributable to the VHA's simpler financing system. These findings suggest that if staffing patterns in the private sector mirrored those of the VHA, nearly 900â¯000 fewer administrative staff might be needed.

Mammalian AIM-2-like receptor (ALR) proteins bind nucleic acids and initiate production of type I interferons or inflammasome assembly, thereby contributing to host innate immunity. In mice, the Alr locus is highly polymorphic at the sequence and copy number level, and we show here that it is one of the most dynamic regions of the genome. One rapidly evolving gene within this region, Ifi207, was introduced to the Mus genome by gene conversion or an unequal recombination event a few million years ago. Ifi207 has a large, distinctive repeat region that differs in sequence and length among Mus species and even closely related inbred Mus musculus strains. We show that IFI207 controls murine leukemia virus (MLV) infection in vivo and that it plays a role in the STING-mediated response to cGAMP, dsDNA, DMXXA, and MLV. IFI207 binds to STING, and inclusion of its repeat region appears to stabilize STING protein. The Alr locus and Ifi207 provide a clear example of the evolutionary innovation of gene function, possibly as a result of host-pathogen co-evolution.IMPORTANCEThe Red Queen hypothesis predicts that the arms race between pathogens and the host may accelerate evolution of both sides, and therefore causes higher diversity in virulence factors and immune-related proteins, respectively . The Alr gene family in mice has undergone rapid evolution in the last few million years and includes the creation of two novel members, MndaL and Ifi207. Ifi207, in particular, became highly divergent, with significant genetic changes between highly related inbred mice. IFI207 protein acts in the STING pathway and contributes to anti-retroviral resistance via a novel mechanism. The data show that under the pressure of host-pathogen coevolution in a dynamic locus, gene conversion and recombination between gene family members creates new genes with novel and essential functions that play diverse roles in biological processes.
