Within the existing fee-for-service healthcare model, ACOs are a mechanism for decreasing costs by improving quality of care. Higher quality organizations incorporate greater levels of coordination of care, which is associated with greater cost savings. Pioneer ACOs have the highest level of integration of services; hence, they save the most money.
New York’s Internet System for Tracking Over-Prescribing (I-STOP) Act, requires prescribers in the state to electronically prescribe controlled substances (EPCS). We examine the effects of this mandate on prescribing patterns of opioids for Medicare Part D beneficiaries. Using 2014-2017 CMS Medicare Part D Prescriber Data, we apply a lagged dependent variable regression approach to identify the impact of I-STOP on the prescription of opioids. In the first year of implementation, the number of opioid prescriptions per prescriber decreased by 5.7 per year. The policy had a larger effect on the prescription of short-acting opioids and on prescribers prescribing medication for predominantly younger beneficiaries. Overall, I-STOP resulted in a reduction in the number of beneficiaries being prescribed opioids and in the number of opioid claims in the state of New York, suggesting positive implications for other states intending to curtail opioid overprescribing and misuse through the use of EPCS.
ImportanceLittle is known about how out-of-pocket burden differs between Medicare and commercial insurance for ultra-expensive drugs.ObjectiveTo investigate out-of-pocket spending for ultra-expensive drugs in the Medicare Part D program vs commercial insurance.Design, Setting, and ParticipantsThis was a retrospective, population-based cohort study of individuals using ultra-expensive drugs included in a 20% nationally random sample of prescription drug claims from Medicare Part D and individuals aged 45 to 64 years using ultra-expensive drugs included in a large national convenience sample of outpatient pharmaceutical claims from commercial insurance plans. Claims data from 2013 through 2019 were used, and data were analyzed in February 2023.Main Outcomes and MeasuresClaims-weighted mean out-of-pocket spending per beneficiary per drug by insurance type, plan, and age.ResultsIn 2019, 37 324 and 24 159 individuals using ultra-expensive drugs were identified in the 20% Part D and commercial samples, respectively (mean [SD] age, 66.2 [11.7] years; 54.9% female). A statistically significant higher share of commercial enrollees vs Part D beneficiaries were female (61.0% vs 51.0%; P < .001), and a statistically significantly lower share were using 3 or more branded medications (28.7% vs 42.6%; P < .001). Mean out-of-pocket spending per beneficiary per drug in 2019 was $4478 in Part D (median [IQR], $4169 [$3369-$5947]) compared with $1821 for commercial (median [IQR], $1272 [$703-$1924]); these differences were statistically significant every year. Differences in out-of-pocket spending comparing commercial enrollees aged 60 to 64 years and Part D beneficiaries aged 65 to 69 years exhibited similar magnitudes and trends. By plan, mean out-of-pocket spending per beneficiary per drug in 2019 was $4301 (median [IQR], $4131 [$3000-$6048]) in Medicare Advantage prescription drug (MAPD) plans, $4575 (median [IQR], $4190 [$3305-$5799]) in stand-alone prescription drug plans (PDPs), $1208 (median [IQR], $752 [$317-$1240]) in health maintenance organization plans, $1569 (median [IQR], $838 [$481-$1472]) in preferred provider organization plans, and $4077 (median [IQR], $2882 [$1075-$4226]) in high-deductible health plans. There were no statistically significant differences between MAPD plans and stand-alone PDPs in any study year. Mean out-of-pocket spending was statistically significantly higher in MAPD plans compared with health maintenance organization plans and in stand-alone PDPs compared with preferred provider organization plans in each study year.Conclusions and RelevanceThis cohort study demonstrated that the $2000 out-of-pocket cap included in the Inflation Reduction Act may substantially moderate the potential increase in spending faced by individuals who use ultra-expensive drugs when moving from commercial insurance to Part D coverage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
