The Association of Medicaid expansion with prescription drug utilization and expenditure among low-income participants with asthma.

OBJECTIVE: This study estimated the association between the 2014 Medicaid expansion and asthma-related prescription drug utilization and expenditures among low-income adult participants with asthma, including those with uncontrolled asthma, in the United States. METHODS: In this national analysis, using a pooled dataset from 2007-2018 Medical Expenditure Panel Surveys (MEPS), regression discontinuity (D-RD) analyses estimated the association between Medicaid expansion and utilization of and expenditures for asthma-related prescription drugs among participants with asthma aged 26-64 with incomes below vs. at/above 138% of the federal poverty level (FPL). A sub-sample analysis was also conducted among participants with uncontrolled asthma. Utilization and expenditure outcomes were estimated using two-part models with logit as the first part and generalized linear models as the second part. RESULTS: Utilization of and total cost for asthma-related prescription drugs increased by 1.89 fills (p < 0.001) and $306.59 (p < 0.001) among participants with asthma with income below 138% FPL after Medicaid expansion. The utilization and total cost of both short-acting bronchodilators and inhaled corticosteroids (ICSs) increased after Medicaid expansion among participants with asthma with incomes below 138% FPL. Among participants with uncontrolled asthma with incomes below 138% FPL, utilization and expenditures increased after Medicaid expansion for all asthma-related prescription drugs and short-acting bronchodilators. CONCLUSION: Medicaid expansion was associated with increased utilization of and total expenditures for both quick-relief and preventive asthma medications among all low-income participants with asthma, but not with utilization of preventive medications among those with uncontrolled asthma.

The Impact of Continuity of Care on Cervical Cancer Screening: How Visit Pattern Affects Guideline Concordance.

Cervical cancer can be prevented and highly curable if detected early. Current guidelines recommend women to receive cervical cancer screening starting at age 21. Our study aims to investigate how improving continuity of care (COC) may influence guideline concordance of cervical cancer screening. Using the eligibility and claims data, we created a person-month panel data set for women who were enrolled in Oregon Medicaid for at least 80% of the period from 2008 to 2015. We then selected our study cohort following the cervical cancer screening guidelines. Our dependent variable is whether a woman received cervical cancer screening concordant with guidelines in a given month, when she did not receive Pap test in the past 36 months and did not receive co-testing of HPV test plus Pap test in the past 60 months. We used both population-averaged logit model and conditional fixed-effect logit model to estimate the association between the guideline concordance and the COC index, after controlling for high risk, pregnancy, age, race, and ethnicity. A total of 466,526 person-month observations were included in our main models. A 0.1 unit increase of the COC score was significantly associated with a decrease in the odds of receiving guideline-concordant cervical cancer screening (population-averaged logit model: OR = 0.988, p < .001; conditional fixed-effect logit model: OR = 0.966, p < .001). Our findings remain robust to a series of sensitivity analyses. A better COC may not be necessarily beneficial to improving cervical cancer prevention. Educations for both physicians and patients should be supplemented to assure quality of preventive care.

Impact of Medicaid expansion in Oregon on access to prenatal care.

Medicaid expansion under the Patient Protection and Affordable Care Act (ACA) has the potential to improve reproductive health by allowing low-income women access to healthcare before and early in pregnancy. The aim of this study was to examine the effects of Oregon's Medicaid expansion on timely and adequate prenatal care. We included live births in Oregon from 2012 to 2015 and used individually-linked birth certificate and Medicaid eligibility data. Outcomes were receipt of first trimester prenatal care and receipt of adequate prenatal care. We also assessed Medicaid enrollment one month prior to pregnancy. We estimated the overall effect of Medicaid expansion on prenatal care utilization using probit regression models. Additionally, we assessed the impact of Medicaid expansion on prenatal care utilization via pre-pregnancy Medicaid enrollment using bivariate probit models. Overall, receipt of first trimester prenatal care increased post-expansion by 1.5 percentage points (p < 0.01) after expansion. Receipt of adequate prenatal care also increased significantly post-expansion with an incremental increase of 2.8 percentage points (p < 0.001). Pre-pregnancy Medicaid enrollment increased following Medicaid expansion (ß = 0.55, p < 0.001) and was associated with both timely (ß = 0.48, p < 0.001) and adequate receipt of prenatal care (ß = 0.14, p < 0.001). Using two years of post-ACA data we found that Medicaid expansion had significant positive associations with Medicaid enrollment prior to pregnancy, which subsequently increased receipt of timely and adequate prenatal care. Our study provides evidence that expanding Medicaid has positive effects on women's use of healthcare.

Postpartum Care Utilization Among Women with Medicaid-Funded Live Births in Oregon.

INTRODUCTION: Postpartum care is an important strategy for preventing and managing chronic disease in women with pregnancy complications (i.e., gestational diabetes (GDM) and hypertensive disorders of pregnancy (HDP)). METHODS: Using a population-based, cohort study among Oregon women with Medicaid-financed deliveries (2009-2012), we examined Medicaid-financed postpartum care (postpartum visits, contraceptive services, and routine preventive health services) among women who retained Medicaid coverage for at least 90 days after delivery (n = 74,933). We estimated postpartum care overall and among women with and without GDM and/or HDP using two different definitions: 1) excluding care provided on the day of delivery, and 2) including care on the day of delivery. Pearson chi-square tests were used to assess differential distributions in postpartum care by pregnancy complications (p < .05), and generalized estimating equations were used to calculate adjusted odds ratios (aORs) with 95% confidence intervals (CIs). RESULTS: Of Oregon women who retained coverage through 90 days after delivery, 56.6-78.1% (based on the two definitions) received any postpartum care, including postpartum visits (26.5%-71.8%), contraceptive services (30.7-35.6%), or other routine preventive health services (38.5-39.1%). Excluding day of delivery services, the odds of receiving any postpartum care (aOR 1.26, 95% CI 1.08-1.47) or routine preventive services (aOR 1.32, 95% CI 1.14-1.53) were meaningfully higher among women with GDM and HDP (reference = neither). DISCUSSION: Medicaid-financed postpartum care in Oregon was underutilized, it varied by pregnancy complications, and needs improvement. Postpartum care is important for all women and especially those with GDM or HDP, who may require chronic disease risk assessment, management, and referrals.

Evaluating the effect of Medicaid expansion on access to preventive reproductive care for women in Oregon.

We evaluated the effect of the Affordable Care Act (ACA) Medicaid expansion on receipt of preventive reproductive services for women in Oregon. First, we compared service receipt among continuing Medicaid enrollees pre- and post-ACA. We then compared receipt among new post-ACA Medicaid enrollees to receipt by continuing enrollees after ACA implementation. Using Medicaid enrollment and claims data, we identified well-woman visits, contraceptive counseling, contraceptive services, sexually transmitted infection (STI) screening, and cervical cancer screening among women ages 15-44 in years when not pregnant. For pre-ACA enrollees, we assessed pre-ACA receipt in 2011-2013 (n = 83,719) and post-ACA receipt in 2014-2016 (n = 103,225). For post-ACA enrollees we similarly assessed post-ACA service receipt (n = 73,945) and compared this to service receipt by pre-ACA enrollees during 2014-2016. We estimated logistic regression models to compare service receipt over time and between enrollment groups. Among pre-ACA enrollees we found lower receipt of all services post-ACA. Adjusted declines ranged from 7.0 percentage points (95% CI: -7.5, -6.4) for cervical cancer screening to 0.4 percentage points [-0.6, -0.2] for STI screening. In 2014-2016, post-ACA enrollees differed significantly from pre-ACA enrollees in receipt of all services, but all differences were <2 percentage points. Despite small declines in receipt of several preventive reproductive services among prior enrollees, the ACA resulted in Medicaid financing of these services for a large number of newly enrolled low-income women in Oregon, which may eventually lead to population-level improvements in reproductive health. These findings among women in Oregon could inform Medicaid coverage efforts in other states.

Determinants of Boarding of Patients with Severe Mental Illness in Hospital Emergency Departments.

BACKGROUND: Boarding of patients in hospital emergency departments (EDs) occurs routinely across the U.S. ED patients with behavioral health conditions are more likely to be boarded than other patients. However, the existing literature on ED boarding of psychiatric patients remains largely descriptive and has not empirically related mental health system capacity to psychiatric boarding. Nor does it show how the mental health system could better address the needs of populations at the highest risk of ED boarding. AIMS OF THE STUDY: We examined extent and determinants of "boarding" of patients with severe mental illness (SMI) in hospital emergency departments (ED) and tested whether greater mental health system capacity may mitigate the degree of ED boarding. METHODS: We linked Oregon's ED Information Exchange, hospital discharge, and Medicaid data to analyze encounters in Oregon hospital EDs from October 2014 through September 2015 by 7,103 persons aged 15 to 64 with SMI (N = 34,207). We additionally utilized Medicaid claims for years 2010-2015 to identify Medicaid beneficiaries with SMI. Boarding was defined as an ED stay over six hours. We estimated a recursive simultaneous-equation model to test the pathway that mental health system capacity affects ED boarding via psychiatric visits. RESULTS: Psychiatric visits were more likely to be boarded than non-psychiatric visits (30.2% vs. 7.4%). Severe psychiatric visits were 1.4 times more likely to be boarded than non-severe psychiatric visits. Thirty-four percent of psychiatric visits by children were boarded compared to 29.6% for adults. Statistical analysis found that psychiatric visit, substance abuse, younger age, black race and urban residence corresponded with an elevated risk of boarding. Discharge destinations such as psychiatric facility and acute care hospitals also corresponded with a higher probability of ED boarding. Greater supply of mental health resources in a county, both inpatient and intensive community-based, corresponded with a reduced risk of ED boarding via fewer psychiatric ED visits. DISCUSSION: Psychiatric visit, severity of psychiatric diagnosis, substance abuse, and discharge destinations are among important predictors of psychiatric ED boarding by persons with SMI. A greater capacity of inpatient and intensive community mental health systems may lead to a reduction in psychiatric ED visits by persons with SMI and thereby decrease the extent of psychiatric ED boarding. IMPLICATIONS FOR HEALTH POLICIES: Continued investment in mental health system resources may reduce psychiatric ED visits and mitigate the psychiatric ED boarding problem.

Racial/Ethnic Variation in the Impact of the Affordable Care Act on Insurance Coverage and Access Among Young Adults.

OBJECTIVES: To examine the impact of the Affordable Care Act's (ACA's) 2010 parental insurance coverage extension to young adults aged 19 to 25 years on health insurance coverage and access to care, including racial/ethnic disparities. METHODS: We pooled data from the Behavioral Risk Factor Surveillance System for the periods 2007 to 2009 and 2011 to 2013 (n = 402 777). We constructed quasiexperimental difference-in-differences models in which adults aged 26 to 35 years served as a control group. Multivariable statistical models controlled for covariates guided by the Andersen model for health care utilization. RESULTS: On average, insurance rates among young adults increased 6.12 percentage points after ACA implementation (P < .001). All racial/ethnic groups experienced increases in coverage. However, the impact varied by race/ethnicity and was largest for Whites. Young adults had a 2.61 percentage point (P < .001) decrease in experiencing barriers to health care because of cost issues after the ACA, with variation by race/ethnicity. CONCLUSIONS: The ACA's expansion had a significant positive effect for young adults acquiring health insurance and reducing cost-related barriers to accessing health care. However, racial/ethnic disparities in coverage and access persist. Public Health Implications. Policies not dependent on parental insurance could further increase access and reduce disparities.

Oregon's Coordinated Care Organizations and Their Effect on Prenatal Care Utilization Among Medicaid Enrollees.

Introduction Previous studies indicate that inadequate prenatal care is more common among women covered by Medicaid compared with private insurance. Increasing the proportion of pregnant women who receive early and adequate prenatal care is a Healthy People 2020 goal. We examined the impact of the implementation of Oregon's accountable care organizations, Coordinated Care Organizations (CCOs), for Medicaid enrollees, on prenatal care utilization among Oregon women of reproductive age enrolled in Medicaid. Methods Using Medicaid eligibility data linked to unique birth records for 2011-2013, we used a pre-posttest treatment-control design that compared prenatal care utilization for women on Medicaid before and after CCO implementation to women never enrolled in Medicaid. Additional stratified analyses were conducted to explore differences in the effect of CCO implementation based on rurality, race, and ethnicity. Results After CCO implementation, mothers on Medicaid had a 13% increase in the odds of receiving first trimester care (OR 1.13, CI 1.04, 1.23). Non-Hispanic (OR 1.20, CI 1.09, 1.32), White (OR 1.20, CI 1.08, 1.33) and Asian (OR 2.03, CI 1.26, 3.27) women on Medicaid were more likely to receive initial prenatal care in the first trimester after CCO implementation and only Medicaid women in urban areas were more likely (OR 1.14, CI 1.05, 1.25) to initiate prenatal care in the first trimester. Conclusion Following Oregon's implementation of an innovative Medicaid coordinated care model, we found that women on Medicaid experienced a significant increase in receiving timely prenatal care.

Preventive Services Use Among African American and Latino Adult Caregivers in South Los Angeles.

BACKGROUND: The burden of informal caregiving is significant and well-documented, yet the evidence is mixed as to whether being a caregiver presents an additional barrier to receiving recommended preventive care. OBJECTIVES: To determine whether (1) caregivers compared with noncaregivers were less likely to receive preventive health services; and (2) higher intensity caregivers were less likely to receive preventive health services than lower intensity caregivers. RESEARCH DESIGN, SUBJECTS, AND MEASURES: Data were from a telephone survey of Latino and African American adults 50 years or older in South Los Angeles (n=702). Outcomes were flu vaccination, pneumococcal vaccination, and colorectal cancer screening. Logistic regression models adjusted for predisposing, enabling, and need factors according to the Andersen Model of Access to Health Care for Low-income Populations. RESULTS: Caregiver type (eg, adult child, nonrelated) was associated with varying odds of receiving a preventive service. Caregivers had lower odds than noncaregivers of receiving preventive services although odds of receiving a flu vaccination improved slightly for caregivers of persons with memory loss compared with other caregivers. More weekly caregiving hours was associated with higher odds of receiving flu vaccination (adjusted odds ratios, 1.1; 95% confidence interval=1.0, 1.1) or colorectal cancer screening (adjusted odds ratios, 1.1; 95% confidence interval=1.0, 1.1). Caregivers and noncaregivers age 65 and older or with chronic conditions were more likely to receive vaccinations. CONCLUSIONS: Preventive service use was influenced by characteristics of the caregiving situation. An opportunity may exist to leverage care recipients' ongoing contact with health care providers to increase caregivers' own access to preventive services.

The Oregon Public Health Policy Institute: Building Competencies for Public Health Practice.

The Oregon Public Health Policy Institute (PHPI) was designed to enhance public health policy competencies among state and local health department staff. The Oregon Health Authority funded the College of Public Health and Human Sciences at Oregon State University to develop the PHPI curriculum in 2012 and offer it to participants from 4 state public health programs and 5 local health departments in 2013. The curriculum interspersed short instructional sessions on policy development, implementation, and evaluation with longer hands-on team exercises in which participants applied these skills to policy topics their teams had selected. Panel discussions provided insights from legislators and senior Oregon health experts. Participants reported statistically significant increases in public health policy competencies and high satisfaction with PHPI overall.

Oregon's experiment in health care delivery and payment reform: coordinated care organizations replacing managed care.

To control Medicaid costs, improve quality, and drive community engagement, the Oregon Health Authority introduced a new system of coordinated care organizations (CCOs). While CCOs resemble traditional Medicaid managed care, they have differences that have been deliberately designed to improve care coordination, increase accountability, and incorporate greater community governance. Reforms include global budgets integrating medical, behavioral, and oral health care and public health functions; risk-adjusted payments rewarding outcomes and evidence-based practice; increased transparency; and greater community engagement. The CCO model faces several implementation challenges. If successful, it will provide improved health care delivery, better health outcomes, and overall savings.

Multimethod evaluation of the VA's peer-to-peer Toolkit for patient-centered medical home implementation.

BACKGROUND: Effective implementation of the patient-centered medical home (PCMH) in primary care practices requires training and other resources, such as online toolkits, to share strategies and materials. The Veterans Health Administration (VA) developed an online Toolkit of user-sourced tools to support teams implementing its Patient Aligned Care Team (PACT) medical home model. OBJECTIVE: To present findings from an evaluation of the PACT Toolkit, including use, variation across facilities, effect of social marketing, and factors influencing use. INNOVATION: The Toolkit is an online repository of ready-to-use tools created by VA clinic staff that physicians, nurses, and other team members may share, download, and adopt in order to more effectively implement PCMH principles and improve local performance on VA metrics. DESIGN: Multimethod evaluation using: (1) website usage analytics, (2) an online survey of the PACT community of practice's use of the Toolkit, and (3) key informant interviews. PARTICIPANTS: Survey respondents were PACT team members and coaches (n = 544) at 136 VA facilities. Interview respondents were Toolkit users and non-users (n = 32). MEASURES: For survey data, multivariable logistic models were used to predict Toolkit awareness and use. Interviews and open-text survey comments were coded using a "common themes" framework. The Consolidated Framework for Implementation Research (CFIR) guided data collection and analyses. KEY RESULTS: The Toolkit was used by 6,745 staff in the first 19 months of availability. Among members of the target audience, 80 % had heard of the Toolkit, and of those, 70 % had visited the website. Tools had been implemented at 65 % of facilities. Qualitative findings revealed a range of user perspectives from enthusiastic support to lack of sufficient time to browse the Toolkit. CONCLUSIONS: An online Toolkit to support PCMH implementation was used at VA facilities nationwide. Other complex health care organizations may benefit from adopting similar online peer-to-peer resource libraries.

Quality of care and health status in Ukraine.

BACKGROUND: We conducted a national level assessment of the quality of clinical care practice in the Ukrainian healthcare system for two important causes of death and chronic disease conditions. We tested two hypotheses: a) quality of care is predicted by physician and facility characteristics and b) health status is predicted by quality of care. METHODS: During 2009-2010 in Ukraine, we collected nationally-representative data from clinical facilities, physicians, Clinical Performance and Value (CPV®) vignettes, patient surveys from the facilities, and from the general population. Each physician completed a written CPV® vignette-a simulated case scenario of a typical patient visit-for each of two clinical cases, congestive heart failure (CHF) and chronic obstructive pulmonary disease (COPD). CPV® vignette scores, calculated as a percentage of all care criteria completed by the physician, were used as the measure of clinical quality of care. Self-reported health measures were collected from exit and household survey respondents. Regression models were developed to test the two study hypotheses. RESULTS: 136 hospitals and 125 polyclinics were surveyed; 1,044 physicians were interviewed and completed CPV® vignettes. On average physicians scored 47.4% on the vignettes. Younger, female physicians provide a higher quality of care-as well as those that have had recent continuing medical education (CME) in chronic disease or health behaviors. Higher quality was associated with better health outcomes. CONCLUSIONS: As low- and middle-income countries around the world are challenged by non-communicable diseases, higher quality of care provided to these populations may result in better outcomes, such as improved health status and life expectancy, and overcome regional shortfalls. Policy efforts that serially evaluate quality may improve chronic disease care.

Oregon's coordinated care organizations: a promising and practical reform model.

Continuing its path of Medicaid program innovation, Oregon recently embarked on a major reform that gives regional coordinated care organizations (CCOs) global budgets and accountability for the physical, behavioral, and dental care of the state's Medicaid beneficiaries (Howard et al. 2014). There are some who maintain that the state's bold reform initiative is overly aggressive in scope and unrealistically optimistic in schedule and may prove to be a costly debacle to the state of Oregon. We argue that the Oregon CCO model is not only bold in its aims and timetable but also realistically achievable.

Variations and practice in the care of patients with rheumatoid arthritis: quality and cost of care.

INTRODUCTION: Variability in treatment is linked to lower quality of care and higher costs. Rheumatoid arthritis (RA) is a chronic inflammatory disease for which care and management may vary considerably among rheumatologists. The extent of this variability and its cost ramifications have not been widely studied. This prospective study evaluated the quality and variability in care and quantified the potential cost implications. METHODS: We used Clinical Performance and Value® vignettes to measure the quality of RA care among community-based rheumatologists. Three online Clinical Performance and Value® vignettes--representing patients likely seen in practice with mild disease activity (case A), worsening disease activity (case B), and stable disease with a complicating comorbidity (case C)--were administered to each rheumatologist. Responses were scored against evidence-based criteria. Costs were computed using current (2011) Medicare pricing. Data were analyzed using t test and fixed-effects analysis of variance. RESULTS: One hundred eight board-certified rheumatologists (72% were male; mean age, 49.1 years) completed the study. Overall quality scores averaged 61.3%. Those employed by a health system or in a multispecialty practice were more likely to score higher. Highest combined scores for diagnosis and treatment were evident with case A (61.7%) and lowest with case C (46.7%). Up to 79% of rheumatologists ordered at least 1 laboratory test that was considered unnecessary by study protocol criteria, incurring a mean excess cost of $37.85 per physician per case. Up to 26.9% rheumatologists prescribed biologic agents that were not indicated based on American College of Rheumatology treatment guidelines, resulting in additional costs of $2041 per patient per month. CONCLUSION: In this study, we observed a wide range of reported practice variability by rheumatologists in the management of RA. This included unnecessary testing and use of biologic agents that increased the costs of treatment. Opportunities for quality improvement and cost control exist in the management of RA.

Domestic Violence and Sterilization Skew in India: An Instrumental Variable Analysis.

The objective of this study was to assess the prevalence of domestic violence in ever-married women in India and analyze the relationship between domestic violence and use of female sterilization as contraception. We analyzed data from the National Family Health Survey 2005-2006 (NFHS3). The Domestic Violence Module of the survey included abuse experiences and reproductive health outcomes of ever-married women aged 15 to 49 years (n = 69,704). The main outcome of interest was female sterilization and domestic violence experience was the main independent variable. Covariates in our multivariate regression models were guided by the socioecological model for domestic abuse. We estimated a reference linear probability model for the dichotomous outcome. We also employed an instrumental variables procedure to strengthen causal inference under such potential sources of bias as measurement error in reporting domestic violence and omitted variables. The reference model showed an increase of 2.1 percentage points (p < .001) in the probability of female sterilization associated with exposure to domestic violence. After correcting the estimate for the measurement error and omitted variable bias, we found that domestic violence was associated with an increase in female sterilization by 6.4 percentage points (p < .001), which is 18% higher than the rate of sterilization among non-victims. In conclusion, our findings imply that domestic violence may lead abuse victims to opt for female sterilization as contraception. Domestic violence is a significant obstacle to efficient contraceptive use. Programs directed toward violence prevention should work conjointly with family planning programs in India.

Improved depression screening and treatment among low-income pregnant and postpartum women following Medicaid expansion in the U.S.

Objective: This study examined the effect of Medicaid expansion in Oregon under the Affordable Care Act on depression screening and treatment among pregnant and postpartum women who gave Medicaid-financed births. Methods: Oregon birth certificates were linked to Medicaid enrollment and claims records for 2011-2016. The sample included a policy group of 1,368 women (n = 2,831) who gave births covered by pregnancy-only Medicaid in the pre-expansion period (before 2014) and full-scope Medicaid in the post-expansion period, and the comparison group of 2,229 women (n = 4,580) who gave births covered by full-scope Medicaid in both pre- and post-expansion periods. Outcomes included indicators for depression screening, psychotherapy, pharmacotherapy, and combined psychotherapy-pharmacotherapy, separately for the first, second, and third trimesters, and 2 and 6 months postpartum. This study utilized a difference-in-differences approach that compared pre-post change in an outcome for the policy group to a counterfactual pre-post change from the comparison group. Results: Medicaid expansion led to a 3.64%-point increase in the rate of depression screening 6 months postpartum, 3.28%-point increase in the rate of psychotherapy 6 months postpartum, and 2.3 and 1%-point increases in the rates of pharmacotherapy and combined treatment in the first trimester, respectively. The relationships were driven by disproportionate gains among non-Hispanic whites and urban residents. Conclusions: Expanding Medicaid eligibility may improve depression screening and treatment among low-income women early in pregnancy and/or beyond the usual two-month postpartum period. However, it does not necessarily reduce racial/ethnic and regional gaps in depression screening and treatment.

Changes in Therapy Utilization at Skilled Nursing Facilities Under Medicare's Patient Driven Payment Model.

OBJECTIVES: The Patient Driven Payment Model (PDPM) was implemented in October 2019 to reimburse skilled nursing facilities (SNFs) based on Medicare patients' clinical and functional characteristics rather than the volume of services provided. This study aimed to examine the changes in therapy utilization and quality of care under PDPM. DESIGN: Quasi-experimental design. SETTING AND PARTICIPANTS: In total, 35,540 short stays by 27,967 unique patients in 121 Oregon SNFs. METHODS: Using Minimum Data Set data from January 2019 to February 2020, we compared therapy utilization and quality of care for Medicare short stays before and after PDPM implementation to non-Medicare short stays. RESULTS: The number of minutes of individual occupational therapy (OT) and physical therapy (PT) per week for Medicare stays decreased by 19.3% (P < .001) and 19.0% (P < .001), respectively, in the first 5 months of PDPM implementation (before the COVID-19 pandemic). The number of group OT and PT minutes increased by 1.67 (P < .001) and 1.77 (P < .001) minutes, respectively. The magnitude of PDPM effects varied widely across stays with different diagnoses. PDPM implementation was not associated with statistically significant changes in length of SNF stay (P = .549), discharge to the community (P = .208), or readmission to the SNF within 30 days (P = .684). CONCLUSIONS AND IMPLICATIONS: SNFs responded to PDPM with a significant reduction in individual OT and PT utilization and a smaller increase in group OT and PT utilization. No changes were observed in length of SNF stay, rates of discharge to the community, or readmission to the SNF in the first 5 months of PDPM implementation. Further research should examine the relative effects of individual and group therapy and their impact on the quality of SNF care.

Functional Limitations and Physical Health in Community-Dwelling Medicare Advantage Beneficiaries: Variation by Race and Hispanic Subgroup.

Objectives: The objective is to examine racial and ethnic heterogeneity in older adults' functional limitations and physical health. Methods: Data were from 2011 to 2015 Health Outcomes Survey of Medicare Advantage beneficiaries 65 and older (N = 828,946). Outcomes were Physical Component Summary (PCS) scores and need for assistance with activities of daily living (ADLs). Six non-Hispanic racial groups and five Hispanic subgroups were analyzed. Regression models adjusted for sociodemographic and health characteristics. Results: White and Asian respondents had the lowest unadjusted ADL difficulty rates and highest PCS scores. In adjusted analyses, Cuban respondents had the highest PCS scores and lowest rates of any ADL difficulty; White respondents had the lowest rates of specific ADL difficulties. Native Hawaiian or other Pacific Islander and multiple Hispanic respondents had the highest ADL difficulty rates. Discussion: Both the healthiest and highest need subgroups of Medicare Advantage beneficiaries were Hispanic. Understanding racial and ethnic subgroup differences may help target interventions to prevent or aid with functional limitations.

Medicaid expansion in Oregon and postpartum healthcare among people with and without prenatal substance use disorder.

Background: People with a maternal substance use disorder (SUD) may experience a lack of access to necessary healthcare and more specifically, postpartum healthcare. It is not known whether increased insurance coverage introduced by Medicaid expansion has improved postpartum healthcare utilization among this population. Methods: Oregon 2008-2016 birth certificates and Medicaid claims were used to examine whether continuous insurance enrollment and postpartum healthcare utilization increased post-Medicaid expansion in a population with and without SUD (n = 9,337). International Classification of Diseases codes were used to identify deliveries, SUD, and postpartum healthcare. Univariable and multivariable generalized linear regression with standard errors clustered by individual were used to estimate the association between Medicaid expansion and postpartum healthcare utilization, stratified by maternal SUD. Results: Among the 10.3% with SUD, expansion was not associated with increased continuous enrollment or postpartum healthcare utilization. Among those without SUD, post-expansion deliveries were associated with increased continuous enrollment (+105.0 days; 95% CI=96.9-113.2), total (+4.4; 95% CI=2.9-6.0), postpartum (+0.3; 95% CI=0.2-0.4), inpatient (+0.9; 95% CI=0.7-1.1), outpatient (+2.3; 95% CI=1.4-3.3), office (+0.9; 95% CI=0.2-1.6), and emergency department (+0.3; 95% CI=0.1-0.5) visits. Among deliveries to postpartum people with SUD, 27.2% had opioid use disorder (OUD); expansion was associated with increased OUD medication use (12.0% vs 18.3%) and number of fills (6.7 vs 16.6). Conclusions: Medicaid expansion in Oregon was only associated with increased Medicaid-financed healthcare utilization for postpartum people without SUD, with the exception of those with OUD, demonstrating the need for assessing various strategies to improve postpartum healthcare utilization.
