Introduction: To assess healthcare professionals' perceptions of rural barriers and facilitators of lung cancer screening program implementation in a Veterans Health Administration (VHA) setting through a series of one-on-one interviews with healthcare team members.

Methods: Based on measures developed using Reach Effectiveness Adoption Implementation Maintenance (RE-AIM), we conducted a cross-sectional qualitative study consisting of one-on-one semi-structured telephone interviews with VHA healthcare team members at 10 Veterans Affairs medical centers (VAMCs) between December 2020 and September 2021. An iterative inductive and deductive approach was used for qualitative analysis of interview data, resulting in the development of a conceptual model to depict rural barriers and facilitators of lung cancer screening program implementation.

Background: Catatonia is an under-recognized disorder characterized by psychomotor (increased, decreased, or abnormal) changes, affective symptoms, and disturbance of volition, which may arise in the setting of decompensated psychiatric or non-psychiatric medical disorders. Genetic studies of catatonia are limited, and to the best of our knowledge no prior genome wide association studies of catatonia have been performed to date.

Methods: First we performed a genome wide association study of catatonia regardless of etiology (psychiatric or non-psychiatric).

Background: Lung cancer screening is a complex clinical process that includes identification of eligible individuals, shared decision-making, tobacco cessation, and management of screening results. Adaptations to the delivery process for lung cancer screening in situ are understudied and underreported, with the potential loss of important considerations for improved implementation. The Framework for Reporting Adaptations and Modifications-Expanded (FRAME) allows for a systematic enumeration of adaptations to implementation of evidence-based practices.

Article Synopsis
  • Veterans think they should get antibiotics when they visit the doctor for respiratory infections, which might affect how happy they are with their visit.
  • A study looked at 1,329 Veterans to see if getting antibiotics or expecting them changed their satisfaction scores after their appointment.
  • The results showed that those who expected antibiotics were less satisfied, even if they didn't receive any, suggesting that meeting their expectations is important for their satisfaction.

Background: The Veterans Health Administration issued policy for lung cancer screening resources at eight Veterans Affairs Medical Centers (VAMCs) in a demonstration project (DP) from 2013 through 2015.

Research Question: Do policies that provide resources increase lung cancer screening rates?

Study Design And Methods: Data from eight DP VAMCs (DP group) and 20 comparable VAMCs (comparison group) were divided into before DP (January 2011-June 2013), DP (July 2013-June 2015), and after DP (July 2015-December 2018) periods. Coprimary outcomes were unique veterans screened per 1,000 eligible per month and those with 1-year (9-15 months) follow-up screening.

Background: As the United States population is aging, there is a chronic shortage of geriatrics- and gerontology- trained clinicians despite a variety of incentives. With primary care clinicians also in short supply, health systems are trying to cope with the increasing demand for care for older adults PURPOSE: The purpose of this study was to examine respondents' willingness to recommend their career to others and beliefs about changes necessary to enhance the supply of appropriately prepared clinicians METHODS: This study used a national survey of a stratified sample of 276 physicians and 134 nurse practitioners working in primary care and geriatric practices.

Findings: Among nurse practitioner respondents, 29% would "definitely" recommend a career as a geriatrician vs.

Purpose: Lung cancer causes the largest number of cancer-related deaths in the United States. Lung cancer incidence rates, mortality rates, and rates of advanced stage disease are higher among those who live in rural areas. Known disparities in lung cancer outcomes between rural and nonrural populations may be in part because of barriers faced by rural populations.

Different staffing configurations in primary and geriatric care practices could have implications for how best to deliver services that are essential for a growing population of older adults. Using data from a 2018 survey of physicians (MDs) and nurse practitioners (NPs) working in primary and geriatric care, we assessed whether different configurations were associated with better or worse performance on a number of standard process measures indicative of comprehensive, high-quality primary care. Practices with a large concentration of MDs had the highest estimated labor costs.
