Association Between Patient Cost Sharing and Cardiac Rehabilitation Adherence.

ABSTRACT: OBJECTIVE:To determine the association between cost sharing and adherence to cardiac rehabilitation (CR). PATIENTS AND METHODS:We collected detailed cost-sharing information for patients enrolled in CR at Baystate Medical Center in Springfield, Massachusetts, including the presence (or absence) and amounts of co-pays and deductibles. We evaluated the association between cost sharing and the total number of CR sessions attended as well as the influence of household income on CR attendance. RESULTS:In 2015, 603 patients enrolled in CR had complete cost-sharing information. In total, 235 (39%) had some form of cost sharing. Of these, 192 (82%) had co-pays (median co-pay, $20; interquartile range [IQR], $10-$32) and 79 (34%) had an unmet deductible (median, $500; IQR, $250-$1800). The presence of any amount or form of cost sharing was associated with 6 fewer sessions of CR (16; IQR, 4-36 vs 10; IQR, 4-27; P<.001). Patients hospitalized in November or December with deductibles that renewed in January attended 4.5 fewer sessions of CR (8.5; IQR, 3.25-12.50 vs 13; IQR, 5.25-36.00; P=.049). After adjustment for differences in baseline characteristics, every $10 increase in co-pay was associated with 1.5 (95% CI, -2.3 to -0.7) fewer sessions of CR (P<.001). Household income did not moderate these relationships. CONCLUSION:Cost sharing was associated with lower CR attendance and exhibited a dose-response relationship such that higher cost sharing was associated with lower CR attendance. Given that CR is cost-effective and underutilized, insurance companies and other payers should reevaluate their cost-sharing policies for CR.

Project description:Study questionWhile physician relationships (measured through shared patients) are associated with clinical and utilization outcomes, the extent to which this is driven by local or global network characteristics is not well established. The objective of this research is to examine the association between local and global network statistics with total medical spending and utilization.Data sourceData used are the 2011 Massachusetts All Payer Claims Database.Study designThe association between network statistics and total medical spending and utilization (using standardized prices) is estimated using multivariate regression analysis controlling for patient demographics and health status.Data collectionWe limit the sample to continuously enrolled commercially insured patients in Massachusetts in 2011.Principal findingsMean patient age was 45 years, and 56.3% of patients were female. 73.4% were covered by a health maintenance organization. Average number of visits was 5.43, with average total medical spending of $4,911 and total medical utilization of $4,252. Spending was lower for patients treated by physicians with higher degree (p<0.001), eigenvector centrality (p<0.001), clustering coefficient (p<0.001), and measures reflecting the normalized degree (p<0.001) and eigenvector centrality (p<0.001) of specialists connected to a patient's PCP. Spending was higher for patients treated by physicians with higher normalized degree, which accounts for physician specialty and patient panel size (p<0.001). Results were similar for utilization outcomes, although magnitudes differed indicating patients may see different priced physicians.ConclusionsGenerally, higher values of network statistics reflecting local connectivity adjusted for physician characteristics are associated with increased costs and utilization, while higher values of network statistics reflecting global connectivity are associated with decreased costs and utilization. As changes in the financing and delivery system advance through policy changes and healthcare consolidation, future research should examine mechanisms through which this structure impacts outcomes and potential policy responses to determine ways to reduce costs while maintaining quality and coordination of care.What this study addsIt is unknown whether local and global measures of physician network connectivity associated with spending and utilization for commercially insured patients?In this social network analysis, we found generally higher values of network statistics reflecting local connectivity are associated with increased costs and utilization, while higher values of network statistics reflecting global connectivity are associated with decreased costs and utilization.Understanding how to influence local and global physician network characteristics may be important for reducing costs while maintaining quality.

Project description:BackgroundAlthough cardiac rehabilitation (CR) is a Class I Guideline recommendation, and has been shown to be a cost-effective intervention after a cardiac event, it has been reimbursed at levels insufficient to cover hospital operating costs. In January 2011, Medicare increased payment for CR in hospital outpatient settings by ≈180%. We evaluated the association between this payment increase and participation in CR of eligible Medicare beneficiaries to better understand the relationship between reimbursement policy and CR utilization.MethodsFrom a 5% Medicare claims sample, we identified patients with acute myocardial infarction, coronary artery bypass surgery, percutaneous coronary intervention, or cardiac valve surgery between January 1, 2009 and September 30, 2012, alive 30 days after their event, with continuous enrollment in Medicare fee-for-service, Part A/B for 4 months. Trends and changes in CR participation were estimated using an interrupted time series approach with a hierarchical logistic model, hospital random intercepts, adjusted for patient, hospital, market, and seasonality factors. Estimates were expressed using average marginal effects on a percent scale.ResultsAmong 76 695 eligible patients, average annual CR participation was 19.5% overall. In the period before payment increase, adjusted annual participation grew by 1.1 percentage points (95% CI, 0.48-2.4). No immediate change occurred in CR participation when the new payment was implemented. In the period after payment increase, on average, 20% of patients participated in CR annually. The annual growth rate in CR participation slowed in the post-period by 1.3 percentage points (95% CI, -2.4 to -0.12) compared with the prior period. Results were somewhat sensitive to time window variations.ConclusionsThe 2011 increase in Medicare reimbursement for CR was not associated with an increase in participation. Future studies should evaluate whether payment did not reach a threshold to incentivize hospitals or if hospitals were not sensitive to reimbursement changes.

Project description:IntroductionThe objective of this study was to measure the influence of differences in out-of-pocket (OOP) costs for type 2 diabetes (T2D) medications on within-patient adherence behavior towards combination drug therapy regimens.MethodsThis was an observational, retrospective, paired sample study in patients with T2D using longitudinal pharmacy data from the 2009-2014 Medical Expenditure Panel Survey (MEPS) augmented with socio-demographic factors. We took a within-patient approach to minimize confounding effects by including patients who maintained the same number of diabetes drug classes over 2 years of MEPS. For each patient, we selected the most and least costly drug classes in the second year and examined their corresponding adherence behavior measured by medication possession ratio. The primary hypothesis tested the significance of the correlation between magnitude of the OOP cost difference and behavioral response in adherence.ResultsAnalysis included 1189 patients representing over 4.2 million US residents with T2D. A significant negative correlation (p < 0.001) was observed between the differences of OOP costs and adherence to the most and least costly medications compared within patients. Reduction in adherence to the most costly medication was generally observed when the difference in OOP costs was greater than $33/month. A greater variability in adherence was observed when the cost difference exceeded $2.39/month as compared to other cost difference ranges (p < 0.001), indicative of choices being made.ConclusionsAs OOP costs increased, adherence variability increased initially until a cost threshold, beyond which the adherence to the more costly medication decreased. In addition to OOP cost, adherence was also influenced by type of medication and self-perception of health. Given the complex correlation between OOP costs and adherence to medication, we suggest a careful approach to cost-sharing in the current insurance drug design and relevant insurance policies.

Project description:ImportanceCardiac rehabilitation (CR) improves survival after acute myocardial infarction (AMI), and referral to CR has been introduced as a performance measure of high-quality care. The association of participation in CR with patients' health status (eg, quality of life, symptoms, and functional status) is poorly defined.ObjectiveTo examine the association of participation in CR with health status outcomes after AMI.Design, setting, and participantsA retrospective cohort study was conducted of patients enrolled in 2 AMI registries: PREMIER, from January 1, 2003, to June 28, 2004, and TRIUMPH, from April 11, 2005, to December 31, 2008. The analytic cohort was restricted to 4929 patients with data available on baseline health status, 6- or 12- month follow-up health status, and participation in CR. Data analysis was performed from 2014 to 2015.ExposuresParticipation in at least 1 CR session within 6 months of hospital discharge.Main outcomes and measuresPatient health status was quantified using the Seattle Angina Questionnaire (SAQ) and the 12-Item Short-Form Health Survey (SF-12). The primary outcomes of interest were the mean differences in SAQ domain scores during the 12 months after AMI between patients who did and did not participate in CR. Secondary outcomes were the mean differences in the SF-12 summary scores and all-cause mortality.ResultsAfter successfully matching the cohorts of the 4929 patients (3328 men and 1601 women; mean [SD] age, 60.0 [12.2] years) for the propensity to participate in CR and comparing the groups using linear, mixed-effects models, mean differences in the SAQ and SF-12 domain scores were similar at 6 and 12 months between the 2012 patients participating in CR (3 were unable to be matched) and the 2894 who did not participate (20 were unable to be matched). At 6 months, the mean difference was -0.76 (95% CI, -2.05 to 0.52) for the SAQ quality of life score, -1.53 (95% CI, -2.57 to -0.49) for the SAQ angina frequency score, 0.38 (95% CI, -0.51 to 1.27) for the SAQ treatment satisfaction score, -0.42 (95% CI, -1.65 to 0.79) for the SAQ physical limitation score, 0.50 (95% CI, -0.22 to 1.22) for the SF-12 physical component score, and 0.13 (95% CI, -0.53 to 0.79) for the SF-12 mental component score. At 12 months, the mean difference was -0.89 (95% CI, -2.20 to 0.43) for the SAQ quality of life score, -1.05 (95% CI, -2.12 to 0.02) for the SAQ angina frequency score, 0.38 (95% CI, -0.54 to 1.29) for the SAQ treatment satisfaction score, -0.14 (95% CI, -1.41 to 1.14) for the SAQ physical limitation score, 0.17 (95% CI, -0.57 to 0.92) for the SF-12 physical component score, and 0.12 (95% CI, -0.56 to 0.80) for the SF-12 mental component score. In contrast, the hazard rate of all-cause mortality (up to 7 years) associated with participating in CR was 0.59 (95% CI, 0.46-0.75).Conclusions and relevanceIn a cohort of 4929 patients with AMI, we found that those who did and did not participate in CR had similar reported health status during the year following AMI; however, participation in CR did confer a significant survival benefit. These findings underscore the need for increased use of validated patient-reported outcome measures to further examine if and how health status can be maximized for patients who participate in CR.
