Drivers of Variation in 90-Day Episode Payments After Percutaneous Coronary Intervention.

ABSTRACT: BACKGROUND:Percutaneous coronary intervention (PCI) is a common and expensive procedure that has become a target for bundled payment initiatives. We described the magnitude and determinants of variation in 90-day PCI episode payments across a diverse array of patients and hospitals. METHODS AND RESULTS:We linked clinical registry data from PCIs performed at 33 Michigan hospitals to 90-day episodes of care constructed using Medicare fee-for-service and commercial insurance claims from January 2012 to October 2016. Payments were price standardized and risk adjusted using clinical and administrative variables in an observed-over-expected framework. Hospitals were stratified into quartiles based on average episode payments. Payment components between the highest and the lowest quartiles were compared with identified drivers of variation (ie, index hospitalization/procedure, readmissions, postacute care, and professional fees). Among 40?925 90-day PCI episodes, the average risk-adjusted 90-day episode payment by hospital ranged between $22?154 and $27?205 with a median of $24?696 (interquartile range, $24?190-$25?643). Hospitals in the lowest and the highest quartiles had average episode payments of $23?744 and $26?504, respectively (difference, $2760). Readmission payments were the primary driver of this variation (46.2%), followed by postacute care (22.6%). Readmissions remained the primary driver of variation in key subgroups, including inpatient and outpatient PCI, as well as PCI for acute myocardial infarction and nonacute myocardial infarction indications. CONCLUSIONS:Substantial hospital-level variation exists in 90-day PCI episode payments. Over half the variation between high- and low-payment hospitals was related to care after the index procedure, primarily because of readmissions and postacute care. Hospitals and policymakers should consider targeting these components when developing initiatives to reduce PCI-related spending.

Project description:ImportanceCoronary artery bypass grafting (CABG) is scheduled to become a mandatory Medicare bundled payment program in January 2018. A contemporary understanding of 90-day CABG episode payments and their drivers is necessary to inform health policy, hospital strategy, and clinical quality improvement activities. Furthermore, insight into current CABG payments and their variation is important for understanding the potential effects of bundled payment models in cardiac care.ObjectiveTo examine CABG payment variation and its drivers.Design, setting, and participantsThis retrospective cohort study used Medicare and private payer claims to identify patients who underwent nonemergent CABG surgery from January 1, 2012, through October 31, 2015. Ninety-day price-standardized, risk-adjusted, total episode payments were calculated for each patient, and hospitals were divided into quartiles based on the mean total episode payments of their patients. Payments were then subdivided into 4 components (index hospitalization, professional, postacute care, and readmission payments) and compared across hospital quartiles. Seventy-six hospitals in Michigan representing a diverse set of geographies and practice environments were included.Main outcomes and measuresNinety-day CABG episode payments.ResultsA total of 5910 patients undergoing nonemergent CABG surgery were identified at 33 of the 76 hospitals; of these, 4344 (73.5%) were men and mean (SD) age was 68.0 (9.3) years. At the patient level, risk-adjusted, 90-day total episode payments for CABG varied from $11 723 to $356 850. At the hospital level, the highest payment quartile of hospitals had a mean total episode payment of $54 399 compared with $45 487 for the lowest payment quartile (16.4% difference, P < .001). The highest payment quartile hospitals compared with the lowest payment quartile hospitals had 14.6% higher index hospitalization payments ($34 992 vs $30 531, P < .001), 33.9% higher professional payments ($8060 vs $6021, P < .001), 29.6% higher postacute care payments ($7663 vs $5912, P < .001), and 35.1% higher readmission payments ($3576 vs $2646, P = .06). The drivers of this variation are diagnosis related group distribution, increased inpatient evaluation and management services, higher utilization of inpatient rehabilitation, and patients with multiple readmissions.Conclusions and relevanceWide variation exists in 90-day CABG episode payments for Medicare and private payer patients in Michigan. Hospitals and clinicians entering bundled payment programs for CABG should work to understand local sources of variation, with a focus on patients with multiple readmissions, inpatient evaluation and management services, and postdischarge outpatient rehabilitation care.

Project description:BackgroundTotal joint arthroplasty (TJA) has been identified as a procedure with substantial variations in inpatient and postacute care payments. Most studies in this area have focused primarily on the Medicare population and rarely have characterized the younger commercially insured populations. Understanding the inpatient and postdischarge care service-component differences across 90-day episodes of care and factors associated with payments for younger patients is crucial for successful implementation of bundled payments in TJA in non-Medicare populations.Purpose(1) To assess the mean total payment for a 90-day primary TJA episode, including the proportion attributable to postdischarge care, and (2) to evaluate the role of procedure, patient, and hospital-level factors associated with 90-day episode-of-care payments in a non-Medicare patient population younger than 65 years.MethodClaims data for 2008 to 2013 from Blue Cross Blue Shield of Texas were obtained for primary TJAs. A total of 11,131 procedures were examined by aggregating payments for the index hospital stay and any postacute care including rehabilitation services and unplanned readmissions during the 90-day postdischarge followup period. A three-level hierarchical model was developed to determine procedure-, patient-, and hospital-level factors associated with 90-day episode-of-care payments.ResultsThe mean total payment for a 90-day episode for TJA was USD 47,700 adjusted to 2013 USD. Only 14% of 90-day episode payments in our population was attributable to postdischarge-care services, which is substantially lower than the percentage estimated in the Medicare population. A prolonged length of stay (rate ratio [RR], 1.19; 95% CI, 1.15-1.23; p ? 0.001), any 90-day unplanned readmission (RR, 1.64; 95% CI, 1.57-1.71; p ? 0.001), computer-assisted surgery (RR, 1.031; 95% CI, 1.004-1.059; p ? 0.05), initial home discharge with home health component (RR, 1.029; 95% CI, 1.013-1.046; p ? 0.001), and very high patient morbidity burden (RR, 1.105; 95% CI, 1.062-1.150; p ? 0.001) were associated with increased TJA payments. Hospital-level factors associated with higher payments included urban location (RR, 1.29; 95% CI, 1.17-1.42; p ? 0.001), lower hospital case mix based on average relative diagnosis related group weight (RR, 0.94; 95% CI, 0.89-0.95; p ? 0.001), and large hospital size as defined by total discharge volume (RR, 1.082; 95% CI, 1.009-1.161; p ? 0.05). All procedure, patient, and hospital characterizing factors together explained 11% of variation among hospitals and 49% of variation among patients.ConclusionInpatient care contributed to a much larger proportion of total payments for 90-day care episodes for primary TJA in our younger than 65-year-old commercially insured population. Thus, inpatient care will continue to be an essential target for cost-containment and delivery strategies. A high percentage of hospital-level variation in episode payments remained unexplained by hospital characteristics in our study, suggesting system inefficiencies that could be suitable for bundling. However, replication of this study among other commercial payers in other parts of the country will allow for conclusions that are more robust and generalizable.Level of evidenceLevel II, economic analysis.

Project description:OBJECTIVES:The purpose of this study was to examine the association of 30-day payments for an episode of heart failure (HF) care at the hospital level with patient outcomes. BACKGROUND:There is increased focus among policymakers on improving value for HF care, given its rising prevalence and associated financial burden in the United States; however, little is known about the relationship between payments and mortality for a 30-day episode of HF care. METHODS:Using Medicare claims data for all fee-for-service beneficiaries hospitalized for HF between July 1, 2011, and June 30, 2014, we examined the association between 30-day Medicare payments at the hospital level (beginning with a hospital admission for HF and across multiple settings following discharge) and patient 30-day mortality using mixed-effect logistic regression models. RESULTS:We included 1,343,792 patients hospitalized for HF across 2,948 hospitals. Mean hospital-level 30-day Medicare payments per beneficiary were $15,423 ± $1,523. Overall observed mortality in the cohort was 11.3%. Higher hospital-level 30-day payments were associated with lower patient mortality after adjustment for patient characteristics (odds ratio per $1,000 increase in payments: 0.961; 95% confidence interval [CI]: 0.954 to 0.967). This relationship was slightly attenuated after accounting for hospital characteristics and HF volume, but remained significant (odds ratio per $1,000 increase: 0.968; 95% CI: 0.962 to 0.975). Additional adjustment for potential mediating factors, including cardiac service capability and post-acute service use, did not significantly affect the relationship. CONCLUSIONS:Higher hospital-level 30-day episode payments were associated with lower patient mortality following a hospitalization for HF. This has implications for policies that incentivize reduction in payments without considering value. Further investigation is needed to understand the mechanisms that underlie this relationship.

Project description:BACKGROUND:Recent policy efforts have focused on improving the value of acute myocardial infarction (AMI) care. Medicare payment programs, for example, increasingly evaluate hospital performance based on spending, as determined by payments made to institutions and providers, and outcome measures for a longitudinal episode of AMI care. Little is known about the relationship between total 30-day payments-both in the inpatient and immediate postdischarge timeframe-and outcomes after an admission for AMI. METHODS AND RESULTS:Using Medicare claims data, we identified Medicare fee-for-service beneficiaries ?65 years of age who were hospitalized at an acute-care hospital for AMI between July 1, 2011, and June 30, 2014, and examined the association between hospital-level 30-day payments for an episode of AMI care and patient 30-day mortality using mixed regression models with a logit link function and random hospital intercepts. Our cohort included 642 105 index hospitalizations for AMI at 2319 acute-care hospitals. Overall mean 30-day episode payments per beneficiary were $22 128 (SD, $1750). The observed 30-day mortality rate was 12.9%. Higher 30-day payments were associated with lower 30-day mortality after adjustment for patient characteristics and comorbidities (adjusted odds ratio for additional $1000 payments, 0.986; 95% confidence interval, 0.979-0.992; P<0.001). Additional adjustment for potential mediating factors, including hospital characteristics, coronary revascularization rates, and discharge disposition, did not significantly attenuate the relationship (adjusted odds ratio for additional $1000 payments, 0.987; 95% confidence interval, 0.980-0.994; P<0.001). CONCLUSIONS:Higher hospital-level 30-day payments-both inpatient and in multiple settings after discharge-for AMI care were associated with lower 30-day mortality among beneficiaries. This may have implications for payment programs that incent reduction in payments without considering value.

Project description:Despite the widespread use of percutaneous coronary intervention (PCI), the appropriateness of these procedures in contemporary practice is unknown.To assess the appropriateness of PCI in the United States.Multicenter, prospective study of patients within the National Cardiovascular Data Registry undergoing PCI between July 1, 2009, and September 30, 2010, at 1091 US hospitals. The appropriateness of PCI was adjudicated using the appropriate use criteria for coronary revascularization. Results were stratified by whether the procedure was performed for an acute (ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, or unstable angina with high-risk features) or nonacute indication.Proportion of acute and nonacute PCIs classified as appropriate, uncertain, or inappropriate; extent of hospital-level variation in inappropriate procedures.Of 500,154 PCIs, 355,417 (71.1%) were for acute indications (ST-segment elevation myocardial infarction, 103,245 [20.6%]; non-ST-segment elevation myocardial infarction, 105,708 [21.1%]; high-risk unstable angina, 146,464 [29.3%]), and 144,737 (28.9%) for nonacute indications. For acute indications, 350,469 PCIs (98.6%) were classified as appropriate, 1055 (0.3%) as uncertain, and 3893 (1.1%) as inappropriate. For nonacute indications, 72,911 PCIs (50.4%) were classified as appropriate, 54,988 (38.0%) as uncertain, and 16,838 (11.6%) as inappropriate. The majority of inappropriate PCIs for nonacute indications were performed in patients with no angina (53.8%), low-risk ischemia on noninvasive stress testing (71.6%), or suboptimal (?1 medication) antianginal therapy (95.8%). Furthermore, although variation in the proportion of inappropriate PCI across hospitals was minimal for acute procedures, there was substantial hospital variation for nonacute procedures (median hospital rate for inappropriate PCI, 10.8%; interquartile range, 6.0%-16.7%).In this large contemporary US cohort, nearly all acute PCIs were classified as appropriate. For nonacute indications, however, 12% were classified as inappropriate, with substantial variation across hospitals.

Project description:BACKGROUND:Same-day discharge (SDD) after elective percutaneous coronary intervention is safe, less costly, and preferred by patients, but it is usually performed in low-risk patients, if at all. To increase the appropriate use of SDD in more complex patients, we implemented a "patient-centered" protocol based on risk of complications at Barnes-Jewish Hospital. METHODS AND RESULTS:Our objectives were as follows: (1) to evaluate time trends in SDD; (2) to compare (a) mortality, bleeding, and acute kidney injury, (b) patient satisfaction, and (c) hospital costs by SDD versus no SDD (NSDD); and (3) to compare SDD eligibility by our patient-centered approach versus Society for Cardiovascular Angiography and Interventions guidelines. Our patient-centered approach was based on prospectively identifying personalized bleeding, mortality, and acute kidney injury risks, with a personalized safe contrast limit and mitigating those risks. We analyzed Barnes-Jewish Hospital's National Cardiovascular Data Registry CathPCI Registry data from July 1, 2009 to September 30, 2015 (N=1752). SDD increased rapidly from 0% to 77% (P<0.001), independent of radial access. Although SDD patients were comparable to NSDD patients, SDD was not associated with adverse outcomes (0% mortality, 0% bleeds, and 0.4% acute kidney injury). Patient satisfaction was high with SDD. Propensity score-adjusted costs were $7331 lower/SDD patient (P<0.001), saving an estimated $1.8 million annually. Only 16 patients (6.95%) met the eligibility for SDD by Society for Cardiovascular Angiography and Interventions guidelines, implying our patient-centered approach markedly increased SDD eligibility. CONCLUSIONS:With a patient-centered approach, SDD rapidly increased and was safe in 75% of patients undergoing elective percutaneous coronary intervention, despite patient complexity. Patient satisfaction was high, and hospital costs were lower. Patient-centered decision making to facilitate SDD is an important opportunity to improve the value of percutaneous coronary intervention.
