Assessment of prevalence and cost of care cascades after routine testing during the Medicare annual wellness visit.
This observational cohort study looked at the prevalence and cost of care cascades after routine tests considered low value in fee-for-service Medicare patients from January 2013 through March 2015 who had gone for an annual wellness visit (AWV). Among the 75,275 AWV recipients identified, 18.6% received at least 1 low-value test including an ECG, urinalysis, or thyrotropin tests. Patients who were younger, White, and lived in urban, high-income areas were most likely to receive those tests. The cost-cascade was considered notable but of modest cost.

Home health utilization in assisted living settings.
The authors explored the growth in the delivery of home health agency (HHA) services to Medicare beneficiaries in assisted living (AL) compared with other home settings between 2012 and 2014. Their findings suggested that there was a slight growth in the share of HHA services being delivered in AL. HHA recipients in AL were more likely to have cognitive and activities of daily living impairments than those receiving HHA services in other settings. This study is among the first of those to examine HHA utilization in AL.

Medicare Advantage and postdischarge quality: evidence from hospital readmissions.
This study compared relative readmission rates for beneficiaries enrolled in Medicare Advantage (MA) and traditional Medicare (TM). HCUP State Inpatient Databases data for 4 states was used from 2009 and 2014. The outcome compared was the probability of a hospital readmission within 30 days of an index admission. There were significantly lower all-cause readmission rates among MA enrollees relative to those in TM in both 2009 and 2014, but MA enrollment was not associated with an increased reduction in readmission rates relative to TM during that time period.

Outcomes of Medicaid home- and community-based long-term services relative to nursing home care among dual eligibles.
This study measured the outcomes of dual-eligible recipients of Medicaid home- and community-based long-term services (HCBS) compared to nursing home residents. The authors used the 2005 and 2012 Medicaid Analytic eXtract (MAX) database, a national compilation of Medicaid claims which merges Medicare claims to identify hospital admissions. A cohort of 1,312,498 older adults dually enrolled in Medicaid and Medicare and using long-term care was tracked. HCBS users were found to have 10 percent points higher annual rates of hospitalization than their nursing home counterparts when selection bias is addressed. The differences persisted across races, dementia status, and intensity of HCBS spending.

Payment incentives and the use of higher-cost drugs: a retrospective cohort analysis of intravenous iron in the Medicare population.
Researchers examined prescribing patterns in the context of intravenous (IV) iron, for which multiple similarly safe and efficacious formulations exist, with wide variations in price. Using Medicare data, they found an increase in the dispensing of a higher-priced IV iron formulation associated with a shortage of a less expensive drug that persisted once the shortage ended. They concluded that their findings in IV iron have broader implications for Part B drug payment policy because the price of the drug determines the physician and health system payment.

Comparative effectiveness of long-term acute care hospital versus skilled nursing facility transfer.
This study compared the effectiveness of long-term acute care hospital (LTACH) use versus skilled nursing facility (SNF) transfer after hospitalization. Medicare claims linked to electronic health record (EHR) data from six Texas hospitals between 2009 and 2010 were used to conduct a retrospective cohort study of hospitalized patients transferred to either an LTACH or SNF and followed for one year. Out of 3505 patients, 18% were transferred to an LTACH and overall were younger, less likely to be female, and white, but sicker than transfers to an SNF. Patients transferred to an LTACH were less likely to survive (59 vs. 65%) or recover (62.5 vs 66%). Adjusting for demographic and clinical confounders found in Medicare claims and EHR data, transfer location was not significantly associated with differences in mortality but was associated with greater Medicare spending.

Opioid prescribing to Medicare Part D enrollees, 2013-2017: shifting responsibility to pain management providers.
This study looked at trends in opioid prescribing frequency to Medicare Part D enrollees from 2013 to 2017 by medical specialty and provider type. The authors analyzed opioid claims and prescribing trends for specialties accounting for ≥1% of all opioid claims. Pain management specialists increased Medicare Part D opioid claims by 27.3% to 1,140 mean claims per provider in 2017. Physical medicine and rehabilitation providers increased claims by 16.9% to 511 mean claims per provider in 2017. All other medical specialties decreased opioid claims during this period, with emergency medicine decreasing the most (-19.9%) and orthopedic surgery (-16%) dropping opioid claims the most of all the other specialties. Overall physician decrease was -5.2%. However opioid claims among dentists (+5.6%) and nonphysician providers (+10.2%) increased during this period.

Evaluation of US hospital episode spending for acute inpatient conditions after the Patient Protection and Affordable Care Act.
This study evaluated the association between enactment of Affordable Care Act (ACA) reforms and 30-day price standardized hospital episode spending for Medicare patients. Reforms to reduce spending were targeted to acute care hospitals and often focused on specific diagnoses such as acute myocardial infarction, heart failure, and pneumonia. The policy evaluation included index discharges between January 2008 and August 31, 2015 from a random 20% sample of Medicare beneficiaries. Three different estimation approaches were used to evaluate the association between reforms and episode spending: difference-in-difference (DID) analysis among acute care hospitals; a DID analysis comparing acute care hospitals and critical care hospitals; and a generalized synthetic control analysis, comparing acute care and critical access hospitals. A total of 7,634,242 index discharges were included. All 3 approaches found that ACA-associated spending reforms were associated with a significant reduction in episode spending.

Geriatric syndrome risk factors among hospitalized postacute Medicare patients.
The purpose of this study was to assess the association of geriatric syndrome risk factors with postacute utilization among hospitalized Medicare patients (both Medicare Advantage [MA] and fee-for-service [FFS] cohorts) and to examine patterns of postacute care for MA and FFS cohorts with high geriatric syndrome risk. The investigators found that geriatric syndrome risk factors not only play a role in postacute care and inpatient utilization in MA and FFS cohorts but also explain different utilizations between MA and FFS cohorts.

Temporal trends in heart failure incidence among Medicare
This retrospective, national cohort study looked at temporal trends in heart failure (HF) incidence among Medicare beneficiaries from 2011 to 2016. There had been a decline in claims during that time period. Five percent of all fee-for-service Medicare beneficiaries with no prior HF diagnosis were followed up from 2011-2016. Annual trends were examined in HF incidence among groups with and without primary HF risk factors (hypertension, diabetes, and obesity) and predisposing cardiovascular conditions (acute myocardial infarction (MI) and atrial fibrillation (AF). Of the approximately 1.8 million Medicare beneficiaries at risk for HF, 249,832 had a new diagnosis of HF. The prevalence of all 5 risk factors had increased during the 5-year study period. There was a relative decline in HF incidence among beneficiaries with primary HF risk factors, but incidence increased among individuals with acute MI and AF.

Medicare accountable care organizations reduce spending on surgery.
This study examined the impact that Medicare accountable care organization (ACO) alignment has on spending for inpatient and outpatient surgical care. Researchers identified adults 65 years of age and older enrolled in fee-for-service Medicare from among a 20% random sample of beneficiaries and distinguished between those aligned and unaligned with a Medicare ACO, then measured payments for surgical services made on the enrollees’ behalf. Findings showed that ACO alignment was associated with savings on surgical care. These savings resulted from increased outpatient surgery and reduced use of inpatient surgery as well as reduced spending per inpatient surgical episode. Greater focus on surgical care to improve the ability of ACOs to control healthcare spending was recommended.

Substantial hospital level variation in all-cause readmission rates among Medicare beneficiaries with serious mental illness.
This study’s purpose was to examine the variation across hospitals in readmissions for patients with serious mental illness (SMI) and differences in the characteristics of hospitals with the highest and lowest readmission rates. A cross-sectional analysis was conducted of pooled inpatient claims from 2013-2016. The 5% sample of fee-for-service Medicare beneficiaries included patients with SMI. The authors identified 2066 hospitals with at least 30 index admissions for Medicare beneficiaries with SMI. Factors most strongly associated with increased risk of readmission included substance use disorder and end stage renal disease. Hospital readmission rates ranged from 7.05% to 15.24%. Hospitals with the lowest adjusted readmission rates were more likely to be teaching hospitals and located in the South or Midwest.

Prehospital and posthospital fall injuries in older US adults.
Investigators estimated the risk of older adult fall injury within and across discrete periods during a 12-month care episode anchored by an acute hospitalization using national data from 2006 to 2014. Participants in this cohort study included Medicare fee-for-service beneficiaries aged 65 and older from the Health and Retirement Study. The investigators found that an episode-based assessment of fall injury illustrated substantial variability in period-specific risks over an extended period including an anchor hospitalization. Risk transitions between periods included sizable increases just before hospitalization that do not fully subside after hospital discharge. Financial incentives to coordinate hospital and posthospital care for patients at risk for fall injury are needed.

Do financial incentives matter? Effects of Medicare price shocks on skilled nursing facility care.
The authors provided new evidence on how Medicare payment changes affect the amount of skilled nursing facility (SNF) care provided to Medicare patients. They found that increases in Medicare payment rates to SNFs increased the total number of Medicare resident days at SNFs. Further, the effects were asymmetric; although Medicare payment increases affected Medicare days, payment decreases did not. They conclude that their results have important implications for policies that alter the Medicare base payment rates to SNFs and other health care providers.

The impact of Medicare's rural add-on payments on supply of home health agencies serving rural counties.
This analysis looked at the impact of Medicare’s rural add-on payments on supply of home health agencies serving rural counties. The authors used data from Home Health Compare. The results suggest that while supply changes are similar in rural counties adjacent to urban areas and urban counties regardless of add-on payments, only higher add-payments of 5 to 10 percent to rural counties keep them on pace with those in urban counties.

Understanding the costs associated with surgical care delivery in the Medicare population.
This study’s objective was to quantify the costs of inpatient and outpatient surgery in the Medicare population. Claims data from a 20% national sample of Medicare beneficiaries was used. Results showed that, while spending on inpatient surgery contributed the most to total surgical payments, it declined over the study period, driven by decreases in index hospitalization and readmissions payments. In contrast, spending on outpatient surgery increased across all sites of care (hospital outpatient department, physician office, and ambulatory surgery center). Ophthalmology and hand surgery witnessed the greatest growth in surgical spending over the study period. Surgical care accounts for half of all Medicare spending.

Beyond comorbidity: expanding the definition and measurement of complexity among older adults using administrative claims data.
Studies of patients with multiple chronic conditions using claims data are often missing important determinants of treatments and outcomes, such as function status and disease severity. In this study, the investigators sought to identify and evaluate a class of function-related indicators (FRIs) from administrative claims data. The investigators concluded that claims data studies that include indicators of potentially diminished patient functional status better capture heterogeneity of patients with multiple chronic conditions.
