Differences in influenza testing and treatment in micropolitan versus metropolitan areas in the U.S. using medicare claims data from 2010 to 2016.
BMC Public Health
January 2025
Epidemiology and Prevention Branch, Influenza Division, National Center for Immunization and Respiratory Diseases, Centers for Disease Control and Prevention, 1600 Clifton Rd, MS 24/7, Atlanta, GA, 30329-4027, USA.
Background: To improve understanding of influenza and rurality, we investigated differences in influenza testing and anti-viral treatment rates between micropolitan (muSAs) and metropolitan statistical areas (MSAs) using national medical claims data over multiple influenza seasons.
Methods: Using billing data from the Centers for Medicare and Medicaid Services for those aged 65 years and older, we estimated weekly rates of ordered rapid influenza diagnostic tests (RIDT) and antivirals (AV) among Medicare enrollees by core-based statistical areas (CBSAs) during 2010-2016. We used Negative Binomial generalized mixed models to estimate adjusted rate ratios (aRR) between MSAs and muSAs, adjusting for clustering by CBSA plus explanatory variables.
Physiologic insulin resensitization lowers cost in patients with diabetes and kidney disease.
Am J Manag Care
January 2025
McGovern Medical School at UTHealth Houston, 4513 Teas St, Bellaire, TX 77401.
Objective: To examine the effect of physiologic insulin resensitization (PIR) on the cost of treating patients with diabetes and chronic kidney disease (CKD).
Study Design: The mean 1-year cost of treating 66 Medicare Advantage patients with diabetes and CKD who were receiving PIR was compared with that of treating 1301 Medicare Advantage patients with diabetes and CKD not receiving PIR. Differences in disease severity were compared using mean risk adjustment factor scores.
Medicare Risk Arrangement and Use and Outcomes Among Physician Groups.
JAMA Netw Open
January 2025
America's Physician Groups, Washington, DC.
Importance: Many physician groups are in 2-sided risk payment arrangements with Medicare Advantage plans (at-risk MA). Analysis of quality and health resource use under such arrangements may inform ongoing Medicare policy concerning payment and service delivery.
Objective: To compare quality and efficiency measures under 2 payment models: at-risk MA and fee-for-service (FFS) MA.
GLP-1RA Use and Thyroid Cancer Risk.
JAMA Otolaryngol Head Neck Surg
January 2025
OptumLabs, Eden Prairie, Minnesota.
Importance: The increasing use of glucagon-like peptide-1 receptor agonists (GLP-1RA) demands a better understanding of their association with thyroid cancer.
Objective: To estimate the risk of incident thyroid cancer among adults with type 2 diabetes being treated with GLP-1RA vs other common glucose-lowering medications.
Design, Setting, And Participants: This was a prespecified secondary analysis of a target trial emulation of a comparative effectiveness study using claims data for enrollees in commercial, Medicare Advantage, and Medicare fee-for-service plans across the US.
