Falls and Fractures Among Medicare Beneficiaries Concurrently Receiving Anti-Dementia Drugs and Potentially Risky Medications
BACKGROUND: Patients with Alzheimer disease and related dementias (ADRD) face risks from medications labeled "potentially inappropriate in older adults" (risky); concurrent receipt of anti-dementia drugs may amplify risk. We studied adverse events among older adults concurrently receiving anti-dementia and risky medications. METHODS: Using 2016-2019 administrative data from a random 40% sample of fee-for-service Medicare beneficiaries receiving a…
Response to Propoxyphene Market Withdrawal
OBJECTIVE: Experts cautioned that patients affected by the November 2010 withdrawal of the opioid analgesic propoxyphene might receive riskier prescriptions. To explore this, we compared drug receipts and outcomes among propoxyphene users before and aftermarket withdrawal. STUDY DESIGN: Using OptumLabs data, we studied 3 populations: commercial, Medicare Advantage (MA) aged (age 65+ y) and MA disabled (age below 65 y) enrollees. The exposed enrol…
Medicaid Expansion and Prescription Trends
BACKGROUND: Opioid overdose deaths in the United States have climbed since 1999. In 2014, the Affordable Care Act prompted some states to expand Medicaid programs, providing low-cost prescription access to millions of Americans. Some have questioned whether Medicaid expansion might worsen the opioid crisis. OBJECTIVE: To test the association between the expansion of state Medicaid programs and Medicaid-paid prescriptions of opioid pain relievers …
ICD-10 Coding Will Challenge Researchers
BACKGROUND: The October 1, 2015 US health care diagnosis and procedure codes update, from the 9th to 10th version of the International Classification of Diseases (ICD), abruptly changed the structure, number, and diversity of codes in health care administrative data. Translation from ICD-9 to ICD-10 risks introducing artificial changes in claims-based measures of health and health services. OBJECTIVE: Using published ICD-9 and ICD-10 definitions …
Antibiotic Use in Cold and Flu Season and Prescribing Quality
BACKGROUND: Excessive antibiotic use in cold and flu season is costly and contributes to antibiotic resistance. The study objective was to develop an index of excessive antibiotic use in cold and flu season and determine its correlation with other indicators of prescribing quality. METHODS AND FINDINGS: We included Medicare beneficiaries in the 40% random sample denominator file continuously enrolled in fee-for-service benefits for 2010 or 2011 (…
Prescription Opioid Use Among Disabled Medicare Beneficiaries
BACKGROUND: Prescription opioid use and overdose deaths are increasing in the United States. Among disabled Medicare beneficiaries under the age of 65, the rise in musculoskeletal conditions as qualifying diagnoses suggests that opioid analgesic use may be common and increasing, raising safety concerns. METHODS: From a 40% random-sample Medicare denominator, we identified fee-for-service beneficiaries under the age of 65 and created annual enroll…
Quality of Care for Cardiometabolic Disease
BACKGROUND: This study examines quality of cardiometabolic care among veterans receiving care in the Veterans Affairs (VA) health system. We assess whether quality of care disparities by mental disorder status are magnified for individuals living in rural areas. RESEARCH DESIGN: We identified all patients in a 2005 national Veterans Administration cardiometabolic quality of care chart review. The intersection of this cohort and VA registries, tha…
Medicaid Prior Authorization and Controlled-Release Oxycodone
BACKGROUND: Since its introduction in 1996, controlled-release (CR) oxycodone use has increased steadily despite its high cost. To control use and expenditures, many Medicaid programs have implemented CR oxycodone prior authorization (PA) policies. Few studies evaluate Medicaid policies or compare lenient and strict policies in multiple states. OBJECTIVE: To estimate the impact of PA on CR oxycodone use by Medicaid beneficiaries. DESIGN: Secondar…
Trends and Geographic Variation of Opiate Medication Use in State Medicaid Fee-For-Service Programs, 1996 to 2002
BACKGROUND: Although studies have documented hospital and surgical service geographic variability, prescription use geographic variability is largely unknown. Opiate pain medications are widely used, particularly because the promulgation of clinical guidelines promoting aggressive pain treatment. This study describes temporal and interstate variability in aggregate prescription opiate medication use within U.S. Medicaid programs. METHODS: A datas…
