  • Trends in Buprenorphine Prescribing Among Adults with Opioid Use Disorder and Coexisting HIV or Viral Hepatitis, 2015–2025

    Open AccessMargaret A Miller, Ashley Hailer et al.ARTICLEAIDS and Behavior2026

    We examined buprenorphine prescribing among adults in the United States with opioid use disorder or other opioid-related diagnoses and coexisting HIV, hepatitis B, or hepatitis C from 2015 to 2025. Using the TriNetX USA Minimal Date Shift Network, we constructed annual cohorts and assessed encounter-day buprenorphine prescribing, with and without chronic pain diagnoses. Prescribing rose from 6% in 2015 to 17% in 2020, then plateaued at 16–19% thr…

  • Post–Affordable Care Act Improvements in Cancer Stage Among Ohio Medicaid Beneficiaries Resulted From an Increase in Stable Coverage

    Siran M Koroukian, Weichuan Dong et al.ARTICLEMedical Care2022Referências: 35

    BACKGROUND: The mechanisms underlying improvements in early-stage cancer at diagnosis following Medicaid expansion remain unknown. We hypothesized that Medicaid expansion allowed for low-income adults to enroll in Medicaid before cancer diagnosis, thus increasing the number of stably-enrolled relative to those who enroll in Medicaid only after diagnosis (emergently-enrolled). METHODS: Using data from the 2011-2017 Ohio Cancer Incidence Surveillan…

  • Markers of Quality Care for Newly Diagnosed People With Epilepsy on Medicaid

    Wyatt P Bensken, Suparna M Navale et al.ARTICLEMedical Care2021Referências: 30

    BACKGROUND: For newly diagnosed people with epilepsy (PWE), proper treatment is important to improve outcomes, yet limited data exist on markers of quality care. OBJECTIVE: Examine markers of quality care for newly diagnosed PWE. METHODS: Using Medicaid claims data (2010-2014) for 15 states we identified adults 18-64 years of age diagnosed with incident epilepsy in 2012 or 2013. We built 5 sequential logistic regression models to evaluate: (1) se…

  • Measuring Multimorbidity

    Jerry Suls, Elizabeth A Bayliss et al.ARTICLEMedical Care2021Referências: 77

    BACKGROUND: Adults have a higher prevalence of multimorbidity-or having multiple chronic health conditions-than having a single condition in isolation. Researchers, health care providers, and health policymakers find it challenging to decide upon the most appropriate assessment tool from the many available multimorbidity measures. OBJECTIVE: The objective of this study was to describe a broad range of instruments and data sources available to ass…

  • Validating the New Primary Care Measure in the Medical Expenditure Panel Survey

    R Henry Olaisen, Susan A Flocke et al.ARTICLEMedical Care2020Referências: 24

    BACKGROUND: The advancement of primary care research requires reliable and validated measures that capture primary care processes embedded within nationally representative datasets. OBJECTIVE: The objective of this study was to assess the validity of a newly developed measure of primary care processes [Medical Expenditure Panel Survey (MEPS)-PC] with preliminary evidence of moderate to excellent reliability. STUDY DESIGN: A retrospective cohort s…

  • Developing a New Measure of Primary Care Using the Medical Expenditure Panel Survey

    R Henry Olaisen, Susan A Flocke et al.ARTICLEMedical Care2019Referências: 28

    OBJECTIVE: To develop and assess the reliability of a measure of primary care using items from the Medical Expenditure Panel Survey (MEPS), a US representative survey of community-dwelling persons. METHODS: On the basis of the domains from the literature on primary care characteristics, we identified relevant items within the 2013-2014 MEPS family of surveys. In a sample of primary survey respondents with at least 1 office-based physician visit i…

  • The Influence of Multimorbidity on Leading Causes of Death in Older Adults With Cognitive Impairment

    Open AccessNicholas K Schiltz, D F Warner et al.ARTICLEJournal of Aging and Health2018

    Objective: The aim of this study is to evaluate the relationship of leading causes of death with gradients of cognitive impairment and multimorbidity. Method: This is a population-based study using data from the linked 1992-2010 Health and Retirement Study and National Death Index ( n = 9,691). Multimorbidity is defined as a combination of chronic conditions, functional limitations, and geriatric syndromes. Regression trees and Random Forest iden…

  • Changes in Case-Mix and Health Outcomes of Medicare Fee-for-Service Beneficiaries and Managed Care Enrollees During the Years 1992–2011

    Siran M Koroukian, Jayasree Basu et al.ARTICLEMedical Care2018Referências: 12

    BACKGROUND: Recent studies suggest that managed care enrollees (MCEs) and fee-for-service beneficiaries (FFSBs) have become similar in case-mix over time; but comparisons of health outcomes have yielded mixed results. OBJECTIVE: To examine changes in differentials between MCEs and FFSBs both in case-mix and health outcomes over time. DESIGN: Temporal study of the linked Health and Retirement Study (HRS) and Medicare data, comparing case-mix and h…

  • Identifying Specific Combinations of Multimorbidity that Contribute to Health Care Resource Utilization

    Nicholas K Schiltz, D F Warner et al.ARTICLEMedical Care2017Referências: 22

    BACKGROUND: Multimorbidity affects the majority of elderly adults and is associated with higher health costs and utilization, but how specific patterns of morbidity influence resource use is less understood. OBJECTIVE: The objective was to identify specific combinations of chronic conditions, functional limitations, and geriatric syndromes associated with direct medical costs and inpatient utilization. DESIGN: Retrospective cohort study using the…

  • Incremental Value of Using Medicaid Claim Files to Study Comorbid Conditions and Treatments in Dually Eligible Beneficiaries

    Cathy J Bradley, Bassam Dahman et al.ARTICLEMedical Care2010Referências: 20

    BACKGROUND: Although investigations using Medicare claims files are ubiquitous in the health services research literature, Medicaid claims files are used less frequently. Nonetheless, Medicaid is the major payer for healthcare among low-income persons. OBJECTIVE: To assess the added value of Medicaid claim files for identifying comorbid conditions and cancer treatments in a dually eligible sample. RESEARCH DESIGN: Data were obtained from linked s…

  • Ability of Medicare Claims Data to Identify Nursing Home Patients

    Siran M Koroukian, Fang Xu et al.ARTICLEMedical Care2008Referências: 7

    BACKGROUND: There are currently no Medicare claims-based algorithms to identify patients receiving nursing home care (NHC). This constitutes an important limitation in outcome studies using population-based data. OBJECTIVES: To assess the ability of claims data to identify patients receiving NHC, using the nursing home Minimum Data Set (MDS) as the gold standard. We hypothesized that physician claims carrying relevant Evaluation and Management (E…

  • Context and Healthcare Access

    David Litaker, Siran M Koroukian et al.ARTICLEMedical Care2005Referências: 45

    BACKGROUND: Although health is influenced by an individual's characteristics and choices, accumulating evidence suggests that contextual attributes may influence a variety of health outcomes. Whether these factors also represent "upstream" factors affecting one's ability to enter the healthcare system is less clear, however. OBJECTIVE: The objective of this study was to assess associations between contextual characteristics and an individual's re…

  • Use of Preventive Services by Medicare Fee-For-Service Beneficiaries

    Siran M Koroukian, David Litaker et al.ARTICLEMedical Care2005Referências: 34

    BACKGROUND: Health care delivery varies with the level of managed care activity (MCA) in an area, potentially affecting health care for those not participating in managed care programs. However, the extent to which MCA is associated with the use of cancer screening by fee-for-service beneficiaries (FFS) is unclear. OBJECTIVE: We sought to study colorectal cancer screening among Medicare FFS beneficiaries in relation to levels of Medicare MCA. RES…
