Psychiatrist networks In Medicare Advantage plans are substantially narrower than in Medicaid and ACA Markets.
The authors used a novel data set that linked insurance network service areas, plans, and providers across Medicare Advantage, Medicaid managed care, and Affordable Care Act plan markets to compare psychiatrist network breadth; their purpose was to assess the percentage of providers in a given area considered in network for a plan. They found that nearly two-thirds of psychiatrist networks in Medicare Advantage contained fewer than 25 percent of providers in a network's service area. They concluded that these findings suggest a certain “narrowness” in psychiatrist networks in Medicare Advantage, which may disadvantage enrollees attempted to obtain mental health services.

Racial and ethnic disparities in opioid access and urine drug screening among older patients with poor-prognosis cancer near the end of life.
This research characterized racial and ethnic disparities and trends in opioid access and urine drug screening (UDS) among older patients dying of cancer, and to explore potential mechanisms. Among 18,549 non-Hispanic White (White), Black, and Hispanic Medicare decedents older than 65 years with poor-prognosis cancers, the authors examined 2007-2019 trends in opioid prescription fills and potency (morphine milligram equivalents [MMEs] per day [MMEDs]) near the end of life (EOL), defined as 30 days before death or hospice enrollment. They found that between 2007 and 2019, White, Black, and Hispanic decedents experienced steady declines in EOL opioid access and rapid expansion of UDS. Compared with White patients, Black and Hispanic patients were less likely to receive any opioid (Black, -4.3 percentage points; Hispanic, -3.6 percentage points) and long-acting opioids (Black, -3.1 percentage points; Hispanic, -2.2 percentage points). They also received lower daily doses (Black, -10.5 MMED; Hispanic, -9.1 MMED) and lower total doses (Black, -210 MMEs; Hispanic, -179 MMEs). Black patients were also more likely to undergo UDS (0.5 percentage points).

Caregiving needs are unmet for many older homeless adults: findings from the Hope Home study.
Researchers described characteristics of older homeless-experienced adults with caregiving need and determined factors associated with having unmet need. Using data from the longitudinal study, Health Outcomes in People Experiencing Homelessness in Older Middle Age (HOPE HOME), they found that better self-rated health and being a man were associated with higher odds of unmet need. Moderate or high-risk substance use was associated with lower odds of unmet need. They recommended interventions that increase caregiving access for homeless-experienced individuals in order to avoid poor health outcomes and costly long-term-care needs due to untreated disabilities.

Comparison of catastrophic out-of-pocket medical expenditure among older adults in the United States and South Korea: what affects the apparent difference?
In the United States seniors aged 65 and older have Medicare and almost-universal coverage, and in South Korea all residents have national health insurance. The purpose of this study was to compare catastrophic out-of-pocket medical spending (defined as out-of-pocket medical spending over the past two years that exceeded 50% of household income) among adults 65 and older in the United States with the same senior-aged population in South Korea. The study found that the proportion of participants with catastrophic out-of-pocket medical expenditures was 5.8% in the US and 3.0% in South Korea. The researchers concluded that exposure to that level of expenditures was significantly higher in the US than South Korea, with the difference attributed to unobservable system level factors rather than observable sociodemographic characteristics.

Understanding variation in postacute care: developing rehabilitation service areas through geographic mapping.
This study’s goal was to demonstrate a method for developing rehabilitation service areas for post-acute care. A secondary analysis of 2013-2014 Medicare records for older patients in Texas (n = 469,172) was conducted. The analysis included admission records for inpatient rehabilitation facilities, skilled nursing facilities, and long-term care hospitals. The authors used Ward’s algorithm to cluster patient ZIP code tabulation areas based on which facilities patients were admitted to for rehabilitation. They set the number of rehabilitation clusters to 22 to allow for comparison to the 22 hospital referral regions. Interclass Correlation Coefficient (ICC) and variance in the number of rehabilitation beds across areas were the methods used to evaluate rehabilitation service areas. The service areas had a higher ICC and variance in beds than the hospital referral regions.

Racial disparities in post-acute home health care referral and utilization among older adults with diabetes.
The purpose of this study was to examine the association between race/ethnicity and hospital discharge to home health care and subsequent utilization of home health care among a cohort of adults (age 50 and older) who experienced a diabetes-related hospitalization. The investigators found that among those discharged to home health care, all non-white racial/ethnic minority patients were less likely to receive services within 14-days.

Post-acute care use patterns among hospital service areas by older adults in the United States: a cross-sectional study.
This study examined post-stroke acute care patterns across Hospital Service Areas among a national stroke cohort of Medicare beneficiaries to determine drivers of variation in post-acute care service utilization. Data was extracted from 2013 to 2014 (174,498 total records across 3232 Hospital Service Areas). Patients’ residence ZIP codes were linked to the facility ZIP code where care was received. Patients were considered a “traveler” if they did not live in the Hospital Service Area where they received care. Only 23.5% of all patients received care in skilled nursing-only Hospital Service Areas although 73.4% of all Hospital Service Areas were skilled nursing-only. Thirty-five percent of all patients traveled to a different Hospital Service Area from their residence. Patients living in skilled nursing-only Hospital Service Areas had more than 5 times the odds of traveling compared to those living in Hospital Service Areas with skilled nursing, inpatient rehabilitation, and long-term care hospital services.

Severe behavioral health manifestations in nursing homes: associations with service availability?
The objective of this study was to examine associations between availability of behavioral health (BH) services and the presence of severe depression, suicidal ideation (SI), and severe aggressive behaviors (ABs) among nursing home (NH) residents. 2017 survey data on BH service availability was obtained from 1,051 NHs and the Minimum Data Set (MDS) to identify long-term stay residents in these facilities (n = 101,238). Odds of severe depression were 21% higher when NHs reported inadequate BH staff education as well as 13% higher for SI and 10% higher for severe ABs among residents in facilities reporting inadequate facility infrastructure. Facility-level factors such as staffing, training, and turnover were also statistically significant associations with these severe BH manifestations.

Assessment of disparities in digital access among Medicare beneficiaries and implications for telemedicine.
In this study, the investigators examined disparities in digital access (ie, access at home to technology that enables video telemedicine visits) among Medicare beneficiaries by socioeconomic and demographic characteristics. The investigators concluded that the proportion of beneficiaries who lacked digital access was higher among those with low socioeconomic status, those 85 years or older, and in communities of color.

Assessment of receipt of the first home health care visit after hospital discharge among older adults.
Investigators examined how often patients referred to home health care at hospital discharge receive it and whether there is evidence of disparities. Their study used Medicare data regarding the postacute home health care setting; participants were Medicare fee-for-service and Medicare Advantage beneficiaries discharged from the hospital with a referral to home health care. They found that only 54% of patients discharged received home health care services within 14 days of discharge. Of the remaining 46% discharged, 37.7% never received any home health care, while 8.3% were institutionalized or died within 14 days without a preceding home health care visit. Patients who were Black or Hispanic received home health at lower rates than did patients who were White. They concluded that disparities in the use of home health care remain an issue in the US.

Evaluating travel distance to radiation facilities among rural and urban breast cancer patients in the Medicare population.
This study characterizes the actual distance older breast cancer patients traveled to radiation treatment and the minimum distance necessary to reach radiation care, and examines whether any patient demographic or clinical factors are associated with greater travel distance. Findings showed that patients living in rural areas traveled on average nearly 3 times as far as those from urban areas, and their nearest facility was more than 4 times farther away. Older age, being single or widowed, and lower household income were significantly associated with shorter actual travel distance, while increasing rurality was significantly associated with greater actual and minimum travel distance to radiation treatment.

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.

Mechanisms of age and race differences in receiving minimally invasive inguinal hernia repair.
Black patients and older adults are less likely to receive minimally invasive hernia repair. In this study, the investigators explored the association between race, age, and surgeon utilization of minimally invasive surgery (MIS) with the likelihood of receiving MIS inguinal hernia repair. The investigators concluded that race differences were explained by surgeon MIS utilization, implicating access to MIS-performing surgeon as a mediator. Conversely, age disparity was independent of MIS utilization, even after adjusting for comorbidities, indicating some degree of provider bias against performing MIS repair in older patients.

The demand for preventive and restorative dental services among older adults.
This study examined the use of preventive and restorative dental services among older adults. Traditional Medicare does not have dental benefits, and older adults must either be employed, have post-retirement dental benefits or spousal coverage, or enroll in a Medicare Advantage program that includes dental coverage. The authors used 2007-2015 Medical Expenditure Panel Survey and supplemental data on dental care prices to estimate the demand for dental care. Dental service was not sensitive to out-of-pocket prices. Older adults with private dental insurance increased preventive service by 25%, and dental coverage through Medicaid increased basic and major service use by 23% and 36%. Women used dental insurance more than men.

Providing behavioral health services in nursing homes is difficult: findings from a national survey.
This study evaluated access to behavioral health services in nursing homes (NHs). A random sample of 2996 NHs in the United States was identified. Two structured surveys were developed with questions on service availability, quality, satisfaction, staffing, staff education, turnover and service barriers. The surveys were mailed to administrators and directors of nursing in NHs between July and December 2017. The results showed that over 30% reported having inadequate coordination of care between NHs and community providers, and 26.2% had inadequate infrastructure for resident referrals or transport. Staff education was the most important factor associated with subpar provision of behavioral health services in nursing homes.

Preventive healthcare-seeking behavior among poor older adults in Mexico: the impact of Seguro Popular, 2000-2012.
This study examined the effect of the Seguro Popular (SP) program in Mexico on preventive care utilization among low-income and uninsured elder beneficiaries. Results of three rounds of the Mexican National Health and Nutrition Survey from 2000, 2006, and 2012 was used. The findings show there was no significant effect on the use of preventive services, including screening for diabetes, hypertension, breast cancer and cervical cancer for adults aged 50 to 75 years.

Regional supply of medical resources and systemic overuse of health care among Medicare beneficiaries.
The goal of this study was to explore health care system factors associated with regional variation in overuse of resources, as measured by the Johns Hopkins Overuse Index (JHOI). Medicare fee-for-service claims data from beneficiaries age 65 was used to calculate the JHOI for 306 hospital referral regions in the U.S. Regions with a higher density of primary care physicians had a lower JHOI, which indicates less systemic overuse. Regional characteristics associated with higher JHOI included the number of acute care hospital beds per 1000 residents and number of hospital-based anesthesiologists, pathologists, and radiologists. The authors conclude that regional variations in health care resources are associated with the level of systemic overuse of health care, and that the role of primary care doctors in reducing overuse deserves further attention.

Health care service use among elderly seasonal migrators.
Little research is available to guide providers and payers on the service use of seasonal migrators. The authors use claims data on fee-for-service (FFS) Medicare beneficiaries' locations throughout the year to (1) identify seasonal migrators and (2) describe the care they receive in each seasonal home, focusing on primary care and emergency department (ED) visits and the relationships between the two.
