Assessment of Differences in Inpatient Rehabilitation Services for Length of Stay and Health Outcomes Between US Medicare Advantage and Traditional Medicare Beneficiaries.

ABSTRACT: Importance:Enrollment in Medicare Advantage (MA) has been increasing and has reached one-third of total Medicare enrollment. Because of data limitations, direct comparison of inpatient rehabilitation services between MA and traditional Medicare (TM) beneficiaries has been very scarce. Subgroups of elderly individuals admitted to inpatient rehabilitation facilities (IRFs) may experience different care outcomes by insurance types. Objective:To measure the differences in length of stay and health outcomes of inpatient rehabilitation services between TM and MA beneficiaries in the US. Design, Setting, and Participants:This multiyear cross-sectional study used the Uniform Data System for Medical Rehabilitation to assess rehabilitation services received by elderly (aged >65 years) Medicare beneficiaries in IRFs between 2007 and 2016 for stroke, hip fracture, and joint replacement. Generalized linear models were used to assess whether an association existed between Medicare insurance type and IRF care outcomes. Models were adjusted for demographic characteristics, clinical conditions, and facility characteristics. Data were analyzed from September 2018 to August 2019. Exposures:Medicare insurance plan type, TM or MA. Main Outcomes and Measures:Inpatient length of stay in IRFs, functional improvements, and possibility of returning to the community after discharge. Results:The sample included a total of 1?028?470 patients (634?619 women [61.7%]; mean [SD] age, 78.23 [7.26] years): 473?017 patients admitted for stroke, 323?029 patients admitted for hip fracture, and 232?424 patients admitted for joint replacement. Individuals enrolled in MA plans were younger than TM beneficiaries (mean [SD] age, 76.96 [7.02] vs 77.95 [7.26] years for stroke, 79.92 [6.93] vs 80.85 [6.87] years for hip fracture, and 74.79 [6.58] vs 75.88 [6.80] years for joint replacement) and were more likely to be black (17?086 [25.5%] vs 54?648 [17.9%] beneficiaries) or Hispanic (14?496 [28.5%] vs 24?377 [8.3%] beneficiaries). The MA beneficiaries accounted for 21.8% (103?204 of 473?017) of admissions for stroke, 11.5% (37?160 of 323?029) of admissions for hip fracture, and 11.8% (27?314 of 232?424) of admissions for joint replacement. The MA beneficiaries had shorter mean lengths of stay than did TM beneficiaries for both stroke (0.11 day; 95% CI, -0.15 to -0.07 day; 1.15% shorter) and hip fracture (0.17 day; 95% CI, -0.21 to -0.13 day; 0.85% shorter). The MA beneficiaries also had higher possibilities of returning to the community than did TM beneficiaries, by 3.0% (95% CI, 2.6%-3.4%) for stroke and 5.0% (95% CI, 4.4%-5.6%) for hip fracture. The shorter length of stay and better ultimate outcomes were achieved without substantially compromising the intermediate functional improvements. Facility type (freestanding vs within an acute care hospital) and patient alternative payment sources other than Medicare (none vs other) partially explained the differences between insurance types. Conclusions and Relevance:This study suggests that MA enrollees experience shorter length of stay and better outcomes for postacute care than do TM beneficiaries in IRFs. The magnitude of the differences depends on treatment deferability, patient sociodemographic subgroups, and facility characteristics.

Project description:ImportanceLow-value care in the Medicare program is prevalent, costly, potentially harmful, and persistent. Although Medicare Advantage (MA) plans can use managed care strategies not available in traditional Medicare (TM), it is not clear whether this flexibility is associated with lower rates of low-value care.ObjectivesTo compare rates of low-value services between MA and TM beneficiaries and explore how elements of insurance design present in MA are associated with the delivery of low-value care.Design, setting, and participantsThis cross-sectional study analyzed beneficiaries enrolled in MA and TM using claims data from a large, national MA insurer and a random 5% sample of TM beneficiaries. The study period was January 1, 2017, through December 31, 2019. All analyses were conducted from July 2021 to March 2022.ExposuresEnrollment in MA vs TM.Main outcomes and measuresLow-value care was assessed using 26 claims-based measures. Regression models were used to estimate the association between MA enrollment and rates of low-value services while controlling for beneficiary characteristics. Stratified analyses explored whether network design, product design, value-based payment, or utilization management moderated differences in low-value care between MA and TM beneficiaries and among MA beneficiaries.ResultsAmong a study population of 2 470 199 Medicare beneficiaries (mean [SD] age, 75.6 [7.0] years; 1 346 777 [54.5%] female; 229 107 [9.3%] Black and 2 126 353 [86.1%] White individuals), 1 527 763 (61.8%) were enrolled in MA and 942 436 (38.2%) were enrolled in TM. Beneficiaries enrolled in MA received 9.2% (95% CI, 8.5%-9.8%) fewer low-value services in 2019 than TM beneficiaries (23.1 vs 25.4 total low-value services per 100 beneficiaries). Although MA beneficiaries enrolled in health management organization and preferred provider organization products received fewer low-value services than TM beneficiaries, the difference was largest for those enrolled in health management organization products (2.6 fewer [95% CI, 2.4-2.8] vs 2.1 fewer [95% CI, 1.9-2.3] services per 100 beneficiaries, respectively). Across primary care payment arrangements, MA beneficiaries received fewer low-value services than TM beneficiaries, with the largest difference observed for MA beneficiaries whose primary care physicians were reimbursed within 2-sided risk arrangements.Conclusions and relevanceIn this cross-sectional study of Medicare beneficiaries, those enrolled in MA had lower rates of low-value care than those enrolled in TM; elements of insurance design present in the MA program and absent in TM were associated with reduction in low-value care.

Project description:ImportanceA growing proportion of the population is enrolling in Medicare Advantage (MA), which typically offers additional benefits compared with traditional Medicare (TM).ObjectiveTo determine whether frailty and frailty trajectories differ between MA enrollees and TM enrollees.Design, setting, and participantsThis retrospective cohort study used data from the National Health and Aging Trends Study (2015-2016). Analyses were conducted from August 2023 to March 2024. Participants were community-dwelling Medicare beneficiaries aged 65 years and older.ExposureEnrollment in MA vs TM.Main outcomes and measuresFrailty was calculated by a frailty index (FI) (range, 0-1, with higher values indicating greater frailty) and the Fried Frailty Phenotype (FFP) score (range, 0-5, with higher values indicating greater frailty). Physical performance, including Short Physical Performance Battery (SPPB) score (range, 0-12, with higher values indicating better performance), and gait speed (meters per second) were measured. The primary outcome was the difference in FI and FFP scores from the 2015 baseline assessment to the 2016 follow-up assessment. Secondary outcomes include the 1-year changes in SPPB and gait speed.ResultsThe final cohort consisted of 7063 participants (2775 [23.1%] aged >80 years; 4040 [54.7%] female), representing a sample of the 38.8 million beneficiaries. There were 2583 (35.0%) MA enrollees (13.6 million) and 4480 (65.0%) TM enrollees (25.2 million). At baseline, the FI score was similar between MA and TM enrollees (mean [SD], 0.22 [0.15] vs 0.21 [0.14]), although MA enrollees had worse phenotypic frailty (496 participants [15.2%] vs 811 participants [13.7%] considered frail by FFP score), SPPB scores (mean [SD], 6.91 [3.34] vs 7.21 [3.27]), and gait speed (0.79 [0.24] m/s vs 0.82 [0.23] m/s) than TM enrollees. One year later, there were no differences between MA and TM enrollees in the 1-year change in FI score (mean [SD], 0.016 [0.071] vs 0.014 [0.066]; adjusted mean difference, 0.001 [95% CI, -0.004 to 0.005]), FFP score (mean [SD], 0.017 [1.004] vs 0.007 [0.958]; adjusted mean difference, -0.009 [95% CI, -0.067 to 0.049]), SPPB score (mean [SD], -0.144 [2.064] vs -0.211 [1.968]; adjusted mean difference, 0.068 [95% CI, -0.076 to 0.212]), and gait speed (mean [SD], -0.0160 [0.148] m/s vs -0.007 [0.148] m/s; adjusted mean difference, -0.010 m/s [95% CI, -0.067 to 0.049 m/s]).Conclusions and relevanceIn this cohort study of Medicare beneficiaries from 2015, MA enrollees experienced similar declines in frailty over 1 year compared with TM enrollees. Future work should examine whether the specific types of services covered by health insurance can impact frailty and health trajectories for older adults.

Project description:ImportanceBetter evidence is needed on whether Medicare Advantage (MA) plans can control the use of postacute care services while achieving excellent outcomes.ObjectiveTo compare self-reported use of postacute care services and outcomes among traditional Medicare (TM) beneficiaries and MA enrollees.Design, setting, and participantsThis cohort study used data from the National Health and Aging Trends Study (NHATS) with linked Medicare enrollment data from 2015 to 2017. Participants were community-dwelling MA or TM beneficiaries 70 years and older; those with dual Medicare and Medicaid eligibility were also identified. Analyses were conducted from May 2022 to February 2023 and were weighted to account for the complex survey design.ExposuresEnrollment in MA and dual eligibility for Medicare and Medicaid.Main outcomes and measuresPostacute care service use including site of use, duration, primary indication, and whether participants met their goals or experienced improved functional status during or after services.ResultsIncluded in the analysis were 2357 Medicare beneficiaries who used postacute care. Of these beneficiaries, 815 (32.6%; 62.0% were females [weighted percentages]) had MA and 1542 (67.4%; 59.5% were females [weighted percentages]) had TM. Enrollees in MA reported using postacute care services across all NHATS survey rounds: between 16.2% (95% CI, 14.3%-18.4%) and 17.7% (95% CI, 15.4%-20.4%) of MA enrollees reported using postacute care services each round, vs 22.4% (95% CI, 20.9%-24.1%) to 24.1% (95% CI, 21.8%-26.6%) of TM beneficiaries (P for all rounds <.002). Enrollees in MA reported less functional improvement during postacute care use (63.1% [95% CI, 59.2%-66.8%] vs 71.7% [95% CI, 68.9%-74.3%], P < .001). Among beneficiaries who ended postacute service use, fewer MA enrollees than TM enrollees reported that they met their goals (70.5% [95% CI, 65.1%-75.3%] vs 76.2% [95% CI, 73.1%-79.1%]; P = .053) or had improved functional status (43.9% [95% CI, 38.9%-49.1%] vs 46.0% [95% CI, 42.5%-49.5%]; P = .42), but differences were not statistically significant. Differences in postacute care use and functional improvement were not statistically significant between MA and TM enrollees with dual eligibility.Conclusions and relevanceIn this cohort study of Medicare beneficiaries, we found that MA enrollees overall used less postacute care services than their TM counterparts. Among users of postacute care services, MA enrollees reported less favorable outcomes compared with TM enrollees. These findings highlight the importance of assessing patient-reported outcomes, especially as MA and other payment models seek to reduce inefficient use of postacute care services.

Project description:ImportancePrivate Medicare Advantage (MA) plans recently surpassed traditional Medicare (TM) in enrollment. However, MA plans are facing scrutiny for burdensome prior authorization and potential rationing of care, including home health. MA beneficiaries are less likely to receive home health, but recent evidence on differences in service intensity and outcomes among home health patients is lacking.ObjectiveTo examine differences in home health service intensity and patient outcomes between MA and TM.Design, setting, and participantsThis cross-sectional study was conducted from January 2019 to December 2022 in 102 home health locations in 19 states and included 178 195 TM and 107 102 MA patients 65 years or older with 2 or fewer 60-day home health episodes. It included a secondary analysis of standardized assessment and visit data. Inverse probability of treatment weighting regression compared service intensity and patient outcomes between MA and TM episodes, accounting for differences in demographic characteristics, medical complexity, functional and cognitive impairments, social environment, caregiver support, and local community factors. Models included office location, year, and reimbursement policy fixed effects. Data were analyzed between September 2023 and July 2024.ExposureTM vs MA plan.Main outcomes and measuresHome health length of stay and number of visits from nursing, physical, occupational, and speech therapy, social work, and home health aides. Patient outcomes included improvement in self-care and mobility function, discharge to the community, and transfer to an inpatient facility during home health.ResultsOf 285 297 total patients, 180 283 (63.2%) were female; 586 (0.2%) were American Indian/Alaska Native, 8957 (3.1%) Asian, 28 694 (10.1%) Black, 7406 (2.6%) Hispanic, 1959 (0.7%) Native Hawaiian/Pacific Islander, 237 017 (83.1%) non-Hispanic White, and 678 (0.2%) multiracial individuals. MA patients had shorter home health length of stay by 1.62 days (95% CI, -1.82 to 1.42) and received fewer visits from all disciplines except social work. There were no differences in inpatient transfers. MA patients had 3% and 4% lower adjusted odds of improving in mobility and self-care, respectively (mobility odds ratio [OR], 0.97; 95% CI, 0.94-0.99; self-care OR, 0.96; 95% CI, 0.92-0.99). MA patients were 5% more likely to discharge to the community compared with TM (OR, 1.05; 95% CI, 1.01-1.08).Conclusions and relevanceThe results of this cross-sectional study suggest that MA patients receive shorter and less intensive home health care vs TM patients with similar needs. Differences may be due to the administrative burden and cost-limiting incentives of MA plans. MA patients experienced slightly worse functional outcomes but were more likely to discharge to the community, which may have negative implications for MA patients, including reduced functional independence or increased caregiver burden.

Project description:BackgroundMedicare Advantage (MA) and Medicare fee-for-service (FFS) plans have different financial incentives. Medicare pays predetermined rates per beneficiary to MA plans for providing care throughout the year, while providers serving FFS patients are reimbursed per utilization event. It is unknown how these incentives affect post-acute care in skilled nursing facilities (SNFs). The objective of this study was to examine differences in rehabilitation service use, length of stay, and outcomes for patients following hip fracture between FFS and MA enrollees.Methods and findingsThis was a retrospective cohort study to examine differences in health service utilization and outcomes between FFS and MA patients in SNFs following hip fracture hospitalization during the period January 1, 2011, to June 30, 2015, and followed up until December 31, 2015. We linked the Master Beneficiary Summary File, Medicare Provider and Analysis Review data, Healthcare Effectiveness Data and Information Set data, the Minimum Data Set, and the American Community Survey. The 6 primary outcomes of interest in this study included 2 process measures and 4 patient-centered outcomes. Process measures included length of stay in the SNF and average rehabilitation therapy minutes (physical and occupational therapy) received per day. Patient-centered outcomes included 30-day hospital readmission, changes in functional status as measured by the 28-point late loss MDS-ADL scale, likelihood of becoming a long-term resident, and successful discharge to the community. Successful discharge from a SNF was defined as being discharged to the community within 100 days of SNF admission and remaining alive in the community without being institutionalized in any acute or post-acute setting for at least 30 days. We analyzed 211,296 FFS and 75,554 MA patients with hip fracture admitted directly to a SNF following an index hospitalization who had not been in a nursing facility or hospital in the preceding year. We used inverse probability of treatment weighting (IPTW) and nursing facility fixed effects regression models to compare treatments and outcomes between MA and FFS patients. MA patients were younger and less cognitively impaired upon SNF admission than FFS patients. After applying IPTW, demographic and clinical characteristics of MA patients were comparable with those of FFS patients. After adjusting for risk factors using IPTW-weighted fixed effects regression models, MA patients spent 5.1 (95% CI -5.4 to -4.8) fewer days in the SNF and received 463 (95% CI to -483.2 to -442.4) fewer minutes of total rehabilitation therapy during the first 40 days following SNF admission, i.e., 12.1 (95% CI -12.7 to -11.4) fewer minutes of rehabilitation therapy per day compared to FFS patients. In addition, MA patients had a 1.2 percentage point (95% CI -1.5 to -1.1) lower 30-day readmission rate, 0.6 percentage point (95% CI -0.8 to -0.3) lower rate of becoming a long-stay resident, and a 3.2 percentage point (95% CI 2.7 to 3.7) higher rate of successful discharge to the community compared to FFS patients. The major limitation of this study was that we only adjusted for observed differences to address selection bias between FFS and MA patients with hip fracture. Therefore, results may not be generalizable to other conditions requiring extensive rehabilitation.ConclusionsCompared to FFS patients, MA patients had a shorter course of rehabilitation but were more likely to be discharged to the community successfully and were less likely to experience a 30-day hospital readmission. Longer lengths of stay may not translate into better outcomes in the case of hip fracture patients in SNFs.

Project description:ImportanceThe 2 primary efforts of Medicare to advance value-based care are Medicare Advantage (MA) and the fee-for-service-based Medicare Shared Savings Program (MSSP). It is unknown how spending differs between the 2 programs after accounting for differences in patient clinical risk.ObjectiveTo examine how spending and utilization differ between MA and MSSP beneficiaries after accounting for differences in clinical risk using data from administrative claims and electronic health records.Design, setting, and participantsThis retrospective economic evaluation used data from 15 763 propensity score-matched beneficiaries who were continuously enrolled in MA or MSSP from January 1, 2014, to December 31, 2018, with diabetes, congestive heart failure (CHF), chronic kidney disease (CKD), or hypertension. Participants received care at a large nonprofit academic health system in the southern United States that bears risk for Medicare beneficiaries through both the MA and MSSP programs. Differences in beneficiary risk were mitigated by propensity score matching using validated clinical criteria based on data from administrative claims and electronic health records. Data were analyzed from January 2019 to May 2022.ExposuresEnrollment in MA or attribution to an accountable care organization in the MSSP program.Main outcomes and measuresPer-beneficiary annual total spending and subcomponents, including inpatient hospital, outpatient hospital, skilled nursing facility, emergency department, primary care, and specialist spending.ResultsThe sample of 15 763 participants included 12 720 (81%) MA and 3043 (19%) MSSP beneficiaries. MA beneficiaries, compared with MSSP beneficiaries, were more likely to be older (median [IQR] age, 75.0 [69.9-81.8] years vs 73.1 [68.3-79.8] years), male (5515 [43%] vs 1119 [37%]), and White (9644 [76%] vs 2046 [69%]) and less likely to live in low-income zip codes (2338 [19%] vs 750 [25%]). The mean unadjusted per-member per-year spending difference between MSSP and MA disease-specific subcohorts was $2159 in diabetes, $4074 in CHF, $2560 in CKD, and $2330 in hypertension. After matching on clinical risk and demographic factors, MSSP spending was higher for patients with diabetes (mean per-member per-year spending difference in 2015: $2454; 95% CI, $1431-$3574), CHF ($3699; 95% CI, $1235-$6523), CKD ($2478; 95% CI, $1172-$3920), and hypertension ($2258; 95% CI, $1616-2,939). Higher MSSP spending among matched beneficiaries was consistent over time. In the matched cohort in 2018, MSSP total spending ranged from 23% (CHF) to 30% (CKD) higher than MA. Adjusting for differential trends in coding intensity did not affect these results. Higher outpatient hospital spending among MSSP beneficiaries contributed most to spending differences between MSSP and MA, representing 49% to 62% of spending differences across disease cohorts.Conclusions and relevanceIn this study, utilization and spending were consistently higher for MSSP than MA beneficiaries within the same health system even after adjusting for granular metrics of clinical risk. Nonclinical factors likely contribute to the large differences in MA vs MSSP spending, which may create challenges for health systems participating in MSSP relative to their participation in MA.

Project description:BackgroundMedicare Advantage (MA) covers more than 1/3rd of all Medicare beneficiaries. MA plans are required to provide the same benefits as Traditional Medicare (TM), but can impose utilization management tools to control costs.ObjectiveTo assess differences between TM and MA enrollees in the probability of receiving prescribed post-acute home health (HH) care and to describe MA plan characteristics associated with HH receipt.DesignRetrospective cross-sectional analysis of claims data, HH patient assessment data, and MA plan data from 2011 to 2017.ParticipantsMedicare beneficiaries aged 66 and older with an incident hospitalization for joint replacement, pneumonia, chronic obstructive pulmonary disease, stroke, urinary tract infection, septicemia, acute renal failure, or congestive heart failure.Main measuresReceipt of prescribed HH as indicated by a HH discharge code and corresponding HH patient assessment within 14 days of hospital discharge.Key resultsThere were 2,723,245 beneficiaries prescribed HH at discharge (68% TM, 32% MA). About 75% of TM enrollees and 62% of MA enrollees received prescribed post-acute HH. In adjusted analyses, MA enrollees had an -11.7 percentage point (pp) (95% confidence interval (CI): -16.8, -6.5) lower probability of receiving HH compared with TM enrollees. In adjusted analyses, HMO enrollees in plans with cost sharing (- 8.4 pp; 95% CI: - 14.3, - 2.5), referrals (- 3.7 pp; 95% CI: - 6.1, - 1.2), and pre-authorization (- 5.1 pp; 95% CI: - 8.3, - 2.0) were less likely to receive prescribed HH. In adjusted analyses, PPO enrollees in plans with cost sharing were -7.0 pp (95% CI: - 12.7, - 1.4) less likely to receive HH, but there was no difference for those with referrals (1.1 pp; 95% CI, - 1.5, 3.7) or pre-authorization (1.6 pp; 95% CI: - 0.6, - 3.9).ConclusionsAmong Medicare beneficiaries, MA enrollees were less likely to receive prescribed post-acute HH compared with TM. As enrollment in MA continues to grow, it is important to examine how differences in utilization relate to outcomes.
