One of the national mortality databases in U.S. is Beneficiary Identification and Record Locator Subsystem (BIRLS) Death File that contains death dates those who have received any benefits from Department Veterans Affairs (VA). The completeness this database was shown to vary widely cohort previous studies. Three other sources are available VA can complement BIRLS File. objective study evaluate accuracy four examine whether these be combined into a with improved accuracy.A random sample...
We examined the impact of access to care characteristics on health use patterns among those veterans dually eligible for Medicare and Veterans Affairs (VA) services.We used a retrospective, cross-sectional design identify who were VA in calendar year 1999. analyzed national utilization claims data. descriptive multivariable generalized ordered logit analyses examine how patient, geographic, environmental factors affect percent reliance inpatient outpatient services.Of 1.47 million our study...
Information about the effectiveness of oral antivirals in preventing short- and long-term COVID-19-related outcomes setting Omicron variant transmission COVID-19 vaccination is limited.
Some persons infected with SARS-CoV-2 experience symptoms or impairments many months after acute infection.To determine the rates, clinical setting, and factors associated documented receipt of COVID-19-related care 3 more infection.This retrospective cohort study used data from US Department Veterans Affairs health system. Participants included a positive test between February 1, 2020, April 30, 2021, who were still alive infection did not have evidence reinfection. Data analysis was...
Positive correlations have been reported between wastewater SARS-CoV-2 concentrations and a community's burden of infection, disease or both. However, previous studies mostly compared to clinical case counts nonrepresentative convenience samples, limiting their quantitative potential.
ABSTRACT Background Information about the effectiveness of oral antivirals in preventing short- and long-term COVID-19-related outcomes during Omicron surge is limited. We sought to determine nirmatrelvir-ritonavir molnupiravir for outpatient treatment COVID-19. Methods conducted three retrospective target trial emulation studies comparing matched patient cohorts who received versus no treatment, Veterans Health Administration (VHA). Participants were VHA care at risk severe COVID-19 tested...
Importance There is increasing recognition of the long-term health effects SARS-CoV-2 infection (sometimes called long COVID ). However, little yet known about clinical diagnosis and management within systems. Objective To describe dominant themes pertaining to in electronic records (EHRs) patients with a diagnostic code for this condition ( International Statistical Classification Diseases Related Health Problems, Tenth Revision [ ICD-10 ] U09.9). Design, Setting, Participants This...
COVID-19 has been linked to the development of many post-COVID-19 conditions (PCCs) after acute infection. Limited information is available on effectiveness oral antivirals used treat in preventing PCCs.
Importance Despite growing evidence of persistent problems after acute COVID-19, how long the excess mortality risk associated with COVID-19 persists is unknown. Objective To measure time course differential among Veterans who had a first-documented infection by separately assessing from later matched groups infected and uninfected individuals survived were uncensored at start each period. Design, Settings, Participants This retrospective cohort study used prospectively collected health...
Care coordination is crucial to avoid potential risks of care fragmentation in people with complex needs. While there are many empirical and conceptual approaches measuring improving coordination, use theory limited by its complexity the wide variability available frameworks. We systematically identified categorized existing theoretical frameworks new ways make theory-to-practice link more accessible. To identify relevant frameworks, we searched MEDLINE®, Cochrane, CINAHL, PsycINFO, SocINDEX...
Little is known about real-world COVID-19 vaccine effectiveness (VE) in racially and ethnically diverse, elderly populations with high comorbidity burden.To determine the of messenger RNA vaccines.Target trial emulation study comparing newly vaccinated persons matched unvaccinated controls.U.S. Department Veterans Affairs health care system.Among receiving system (n = 5 766 638), those who received at least 1 dose Moderna or Pfizer-BioNTech from 11 December 2020 to 25 March 2021 2 099 871)...
The effectiveness of a third mRNA COVID-19 vaccine dose (booster dose) against the Omicron (B.1.1.529) variant is uncertain, especially in older, high-risk populations.To determine booster (VE) SARS-CoV-2 infection, hospitalization, and death era by type, primary time since vaccination, age, comorbidity burden.Retrospective matched cohort study designed to emulate target trial vaccination versus no booster, conducted from 1 December 2021 31 March 2022.U.S. Department Veterans Affairs health...
Inferior outcomes after kidney transplantation among African Americans are poorly understood. It was hypothesized that unequal access to medical care transplant recipients might contribute worse posttransplantation and racial disparities in would be less pronounced patients who receive health within versus outside the Department of Veterans Affairs (VA), because eligible veterans VA entitled universal care, including coverage prescription drugs. A study cohort 79,361 were undergoing their...
Patient race in the Department of Veterans Affairs (VA) information system was previously recorded based on an administrative or clinical employee's observation. Since 2003, VA started to collect self-reported compliance with a new federal guideline. We investigated implications this transition for using race/ethnicity data multi-year trends and other healthcare systems that make transition.All unique users services 2004 were compared their prior observer-recorded from 1997-2002 (N =...
A Department of Veterans Affairs Cooperative Study randomized high-risk patients with medically refractory myocardial ischemia, a group largely excluded from previous trials, to urgent revascularization either percutaneous coronary intervention (PCI) or artery bypass grafting (CABG). The present study examined the cost-effectiveness PCI versus CABG for these patients.Of 454 at 16 medical centers, 445 were available economic analysis (218 and 227 patients). Total costs assessed 3 5 years...
The distributions of medical costs are often skewed to the right because small numbers patients use large amounts health care resources. Using data from a study colon cancer costs, we show, by example, impact and magnitude outliers influential observations on compared effects statistical costing methods for addressing disproportionate influence observations. We used retrospective cohort 3,842 elderly veterans with who were enrolled in from, both Department Veterans Affairs Medicare...
