Association of intrapartum severe maternal morbidity with receipt of postpartum contraception among Medicaid recipients.

OBJECTIVES: We sought to determine the association between intrapartum severe maternal morbidity and receipt of postpartum contraception within 60 days among Medicaid recipients in Oregon and South Carolina. STUDY DESIGN: We conducted a historical cohort study of all Medicaid births in Oregon and South Carolina from 2011 to April 2018. Intrapartum severe maternal morbidity was measured using diagnosis and procedure codes according to the Center for Disease Control's classifications. Our primary outcome of interest was receipt of postpartum contraception within 60 days of birth. We captured permanent and reversible forms of contraception. We examined the association of intrapartum severe maternal morbidity with receipt of postpartum contraception, and whether this varied by type of Medicaid (Traditional vs Emergency). We used Poisson regression models with robust (sandwich) estimation of variance to calculate relative risk (RR) for each model. RESULTS: Our analytic cohort included 347,032 births. We identified 3079 births with evidence of intrapartum severe maternal morbidity (0.9% of all births). When adjusted for maternal age, rural vs urban status, and state of residence, Medicaid beneficiaries with births complicated by intrapartum severe maternal morbidity are 7% less likely to receive any contraception (RR 0.93, 95% CI (0.91, 0.95)) by 60 days postpartum. Among births complicated by severe maternal morbidity we found that Emergency Medicaid recipients were 92% less likely than Traditional Medicaid recipients to receive any method of contraception (RR 0.08, 95% CI (0.08, 0.08)). CONCLUSIONS: Medicaid recipients experiencing intrapartum severe maternal morbidity are less likely to receive contraception within 60 days than Medicaid beneficiaries with uncomplicated births. IMPLICATIONS: Medicaid recipients with intrapartum severe maternal morbidity are less likely to receive postpartum contraception, than Medicaid beneficiaries without severe maternal morbidity.

Medicaid Reimbursement For Psychiatric Services: Comparisons Across States And With Medicare.

Medicaid is characterized by low rates of provider participation, often attributed to reimbursement rates below those of commercial insurance or Medicare. Understanding the extent to which Medicaid reimbursement for mental health services varies across states may help illuminate one lever for increasing Medicaid participation among psychiatrists. We used publicly available Medicaid fee-for-service schedules from state Medicaid agency websites in 2022 to construct two indices for a common set of mental health services provided by psychiatrists: a Medicaid-to-Medicare index to benchmark each state's Medicaid reimbursement with that of Medicare for the same set of services, and a state-to-national Medicaid index comparing each state's Medicaid reimbursement with an enrollment-weighted national average. On average, Medicaid paid psychiatrists at 81.0 percent of Medicare rates, and a majority of states had a Medicaid-to-Medicare index that was less than 1.0 (median, 0.76). State-to-national Medicaid indices for psychiatrists' mental health services ranged from 0.46 (Pennsylvania) to 2.34 (Nebraska) but did not correlate with the supply of Medicaid-participating psychiatrists. As policy makers look to reimbursement rates as one strategy to address ongoing mental health workforce shortages, comparing Medicaid payment across states may help benchmark ongoing state and federal proposals.

An observational study of workflows to support fecal testing for colorectal cancer screening in primary care practices serving Medicaid enrollees.

BACKGROUND: Screening supports early detection and treatment of colorectal cancer (CRC). Provision of fecal immunochemical tests/fecal occult blood tests (FIT/FOBT) in primary care can increase CRC screening, particularly in populations experiencing health disparities. This study was conducted to describe clinical workflows for FIT/FOBT in Oregon primary care practices and to identify specific workflow processes that might be associated (alone or in combination) with higher (versus lower) CRC screening rates. METHODS: Primary care practices were rank ordered by CRC screening rates in Oregon Medicaid enrollees who turned age 50 years from January 2013 to June 2014 (i.e., newly age-eligible). Practices were recruited via purposive sampling based on organizational characteristics and CRC screening rates. Data collected were from surveys, observation visits, and informal interviews, and used to create practice-level CRC screening workflow reports. Data were analyzed using descriptive statistics, qualitative data analysis using an immersion-crystallization process, and a matrix analysis approach. RESULTS: All participating primary care practices (N=9) used visit-based workflows, and four higher performing and two lower performing used population outreach workflows to deliver FIT/FOBTs. However, higher performing practices (n=5) had more established workflows and staff to support activities. Visit-based strategies in higher performing practices included having dedicated staff identify patients due for CRC screening and training medical assistants to review FIT/FOBT instructions with patients. Population outreach strategies included having clinic staff generate lists and check them for accuracy prior to direct mailing of kits to patients. For both workflow types, higher performing clinics routinely utilized systems for patient reminders and follow-up after FIT/FOBT distribution. CONCLUSIONS: Primary care practices with higher CRC screening rates among newly age-eligible Medicaid enrollees had more established visit-based and population outreach workflows to support identifying patients due for screening, FIT/FOBT distribution, reminders, and follow up. Key to practices with higher CRC screening was having medical assistants discuss and review FIT/FOBT screening and instructions with patients. Findings present important workflow processes for primary care practices and may facilitate the implementation of evidence-based interventions into real-world, clinical settings.

Project Nurture Integrates Care And Services To Improve Outcomes For Opioid-Dependent Mothers And Their Children.

Children born to women with substance use disorders are at high risk for early foster care placement, which is associated with long-term adverse outcomes for children and places additional pressure on state budgets. Poor outcomes for drug-dependent mothers and their children may be further exacerbated by a lack of coordination between the health care and human services sectors. Project Nurture is an innovative model in Portland, Oregon, that integrates maternity care, substance use treatment, and social service coordination for Medicaid beneficiaries. This study assessed the impact of Project Nurture on a range of patient and child welfare outcomes. Among the "treatment" population of opioid-dependent women enrolled in Medicaid, Project Nurture was associated with reductions in child maltreatment, placement of children in foster care, and increases in both prenatal visits and maternal lengths-of-stay in the hospital, compared to opioid-dependent women enrolled in Medicaid in Oregon counties not served by the project. These results suggest that models based in a clinical setting that engage the human services sector may improve overall outcomes, even though the difficulty in sharing savings across sectors presents challenges to sustainability.

Does a transition to accountable care in Medicaid shift the modality of colorectal cancer testing?

BACKGROUND: Health care reform is changing preventive services delivery. This study explored trajectories in colorectal cancer (CRC) testing over a 5-year period that included implementation of 16 Medicaid Accountable Care Organizations (ACOs, 2012) and Medicaid expansion (2014) - two provisions of the Affordable Care Act (ACA) - within the state of Oregon, USA. METHODS: Retrospective analysis of Oregon's Medicaid claims for enrollee's eligible for CRC screening (50-64 years) spanning January 2010 through December 2014. Our analysis was conducted and refined April 2016 through June 2018. The analysis assessed the annual probability of patients receiving CRC testing and the modality used (e.g., colonoscopy, fecal testing) relative to a baseline year (2010). We hypothesized that CRC testing would increase following Medicaid ACO formation - called Coordinated Care Organizations (CCOs). RESULTS: A total of 132,424 unique Medicaid enrollees (representing 255,192 person-years) met inclusion criteria over the 5-year study. Controlling for demographic and regional factors, the predicted probability of CRC testing was significantly higher in 2014 (+ 1.4 percentage points, p < 0.001) compared to the 2010 baseline but not in 2012 or 2013. Increased fecal testing using Fecal Occult Blood Tests (FOBT) or Fecal Immunochemical Tests (FIT) played a prominent role in 2014. The uptick in statewide fecal testing appears driven primarily by a subset of CCOs. CONCLUSIONS: Observed CRC testing did not immediately increase following the transition to CCOs in 2012. However increased testing in 2014, may reflect a delay in implementation of interventions to increase CRC screening and/or a strong desire by newly insured Medicaid CCO members to receive preventive care.

Access to treatment for alcohol use disorders following Oregon's health care reforms and Medicaid expansion.

The study examines impacts of delivery system reforms and Medicaid expansion on treatment for alcohol use disorders within the Oregon Health Plan (Medicaid). Diagnoses, services and pharmacy claims related to alcohol use disorders were extracted from Medicaid encounter data. Logistic regression and interrupted time series analyses assessed the percent with alcohol use disorder entering care and the percent receiving pharmacotherapy before (January 2010-June 2012) and after (January 2013-June 2015) the initiation of Oregon's Coordinated Care Organization (CCO) model (July 2012-December 2012). Analyses also examined changes in access following Medicaid expansion (January 2014). Treatment entry rates increased from 35% in 2010 to 41% in 2015 following the introduction of CCOs and Medicaid expansion. The number of Medicaid enrollees with a diagnosed alcohol use disorder increased about 150% from 10,360 (2013) to 25,454 (2014) following Medicaid expansion. Individuals with an alcohol use disorder who were prescribed a medication to support recovery increased from 2.3% (2010) to 3.8% (2015). In Oregon, Medicaid expansion and health care reforms enhanced access and improved treatment initiation for alcohol use disorders.

Decomposing Medicaid Spending During Health System Reform and ACA Expansion: Evidence From Oregon.

BACKGROUND: Expansion of the Medicaid program is likely to create new budgetary pressures at the state and federal levels, creating a need for greater understanding of how program dollars are allocated and what drives spending growth. OBJECTIVE: To characterize Oregon Medicaid expenditures across diseases and medical conditions, during periods of payment reform and coverage expansion. RESEARCH DESIGN: Decomposition of changes in Medicaid expenditures using a person-based allocation of spending across 50 diseases/medical conditions. Four indices describe changes in costs per enrolled member, demographic shifts, prevalence of treated disease/condition, and costs per treated member. SUBJECTS: Oregon Medicaid beneficiaries during 2011 (N=597,422), 2013 (N=614,858), and 2014 (N=978,237). RESULTS: Expenditures on pregnancy/birth and mental conditions accounted for 24% of 2011 spending. Oregon's 2012 payment reform was associated with reduced spending attributable primarily to decreased prevalence of treated conditions. The 2014 Medicaid expansion was marked by lower pregnancy and mental health expenditures and higher spending on treatment for substance use and heart disease. CONCLUSIONS: Medicaid spending is concentrated among a small group of medical conditions, not all of which are typically associated with the program. The relative expenditure burdens for some conditions are likely to change with health system reform and enrollment expansions. Decomposition into 4 indices and reporting by disease/condition elucidate variability in drivers of cost growth.

Quality Metrics and Systems Transformation: Are We Advancing Alcohol and Drug Screening in Primary Care?

OBJECTIVE: To examine the influence of Oregon's coordinated care organizations (CCOs) and pay-for-performance incentive model on completion of screening and brief intervention (SBI) and utilization of substance use disorder (SUD) treatment services. DATA SOURCES/STUDY SETTING: Secondary analysis of Medicaid encounter data from 2012 to 2015 and semiannual qualitative interviews with stakeholders in CCOs. STUDY DESIGN: Longitudinal mixed-methods design with simultaneous data collection with equal importance. DATA COLLECTION/EXTRACTION METHODS: Qualitative interviews were recorded, transcribed, and coded in ATLAS.ti. Quantitative data included Medicaid encounters 30 months prior to CCO implementation, a 6-month transition period, and 30 months following CCO implementation. Data were aggregated by half-year with analyses restricted to Medicaid recipients 18-64 years of age enrolled in a CCO, not eligible for Medicare coverage or Medicaid expansion. PRINCIPAL FINDINGS: Quantitative analysis documented a significant increase in SBI rates coinciding with CCO implementation (0.1 to 4.6 percent). Completed SBI was not associated with increased initiation in treatment for SUD diagnoses. Qualitative analysis highlighted importance of aligning incentives, workflow redesign, and leadership to facilitate statewide SBI. CONCLUSIONS: Results provide modest support for use of a performance metric to expand SBI in primary care. Future research should examine health reform efforts that increase initiation and engagement in SUD treatment.

Geographic and population-level disparities in colorectal cancer testing: A multilevel analysis of Medicaid and commercial claims data.

Morbidity and mortality from colorectal cancer (CRC) can be attenuated through guideline concordant screening and intervention. This study used Medicaid and commercial claims data to examine individual and geographic factors associated with CRC testing rates in one state (Oregon). A total of 64,711 beneficiaries (4516 Medicaid; 60,195 Commercial) became newly age-eligible for CRC screening and met inclusion criteria (e.g., continuously enrolled, no prior history) during the study period (January 2010-December 2013). We estimated multilevel models to examine predictors for CRC testing, including individual (e.g., gender, insurance, rurality, access to care, distance to endoscopy facility) and geographic factors at the county level (e.g., poverty, uninsurance). Despite insurance coverage, only two out of five (42%) beneficiaries had evidence of CRC testing during the four year study window. CRC testing varied from 22.4% to 46.8% across Oregon's 36 counties; counties with higher levels of socioeconomic deprivation had lower levels of testing. After controlling for age, beneficiaries had greater odds of receiving CRC testing if they were female (OR 1.04, 95% CI 1.01-1.08), commercially insured, or urban residents (OR 1.14, 95% CI 1.07-1.21). Accessing primary care (OR 2.47, 95% CI 2.37-2.57), but not distance to endoscopy (OR 0.98, 95% CI 0.92-1.03) was associated with testing. CRC testing in newly age-eligible Medicaid and commercial members remains markedly low. Disparities exist by gender, geographic residence, insurance coverage, and access to primary care. Work remains to increase CRC testing to acceptable levels, and to select and implement interventions targeting the counties and populations in greatest need.

Oregon's Medicaid Reform And Transition To Global Budgets Were Associated With Reductions In Expenditures.

In 2012 Oregon initiated an ambitious delivery system reform, moving the majority of its Medicaid enrollees into sixteen coordinated care organizations, a type of Medicaid accountable care organization. Using claims data, we assessed measures of access, appropriateness of care, utilization, and expenditures for five service areas (evaluation and management, imaging, procedures, tests, and inpatient facility care), comparing Oregon to the neighboring state of Washington. Overall, the transformation into coordinated care organizations was associated with a 7 percent relative reduction in expenditures across the sum of these services, attributable primarily to reductions in inpatient utilization. The change to coordinated care organizations also demonstrated reductions in avoidable emergency department visits and improvements in some measures of appropriateness of care, but also exhibited reductions in primary care visits, a potential area of concern. Oregon's coordinated care organizations could provide lessons for controlling health care spending for other state Medicaid programs.

Early Performance in Medicaid Accountable Care Organizations: A Comparison of Oregon and Colorado.

Importance: Several state Medicaid reforms are under way, but the relative performance of different approaches is unclear. Objective: To compare the performance of Oregon's and Colorado's Medicaid Accountable Care Organization (ACO) models. Design, Setting, and Participants: Oregon initiated its Medicaid transformation in 2012, supported by a $1.9 billion investment from the federal government, moving most Medicaid enrollees into 16 Coordinated Care Organizations, which managed care within a global budget. Colorado initiated its Medicaid Accountable Care Collaborative in 2011, creating 7 Regional Care Collaborative Organizations that received funding to coordinate care with providers and connect Medicaid enrollees with community services. Data spanning July 1, 2010, through December 31, 2014 (18 months before intervention and 24 months after intervention, treating 2012 as a transition year) were analyzed for 452 371 Oregon and 330 511 Colorado Medicaid enrollees, assessing changes in outcomes using difference-in-differences analyses of regional focus, primary care homes, and care coordination. Oregon's Coordinated Care Organization model was more comprehensive in its reform goals and in the imposition of downside financial risk. Exposures: Regional focus, primary care homes, and care coordination in Medicaid ACOs. Main Outcomes and Measures: Performance on claims-based measures of standardized expenditures and utilization for selected services, access, preventable hospitalizations, and appropriateness of care. Results: In a total of 782 882 Medicaid enrollees, 45.0% were male, with mean (SD) age 16.74 (14.41) years. Standardized expenditures for selected services declined in both states during the 2010-2014 period, but these decreases were not significantly different between the 2 states. Oregon's model was associated with reductions in emergency department visits (-6.28 per 1000 beneficiary-months; 95% CI, -10.51 to -2.05) and primary care visits (-15.09 visits per 1000 beneficiary-months; 95% CI, -26.57 to -3.61), improvements in acute preventable hospital admissions (-1.01 admissions per 1000 beneficiary-months; 95% CI, -1.61 to -0.42), 3 of 4 measures of access (well-child visits, ages 3-6 years, 2.69%; 95% CI, 1.20% to 4.19%; adolescent well-care visits, 6.77%; 95% CI, 5.22% to 8.32%; and adult access to preventive ambulatory care, 1.26%; 95% CI, 0.28% to 2.25%), and 1 of 4 measures of appropriateness of care (avoidance of head imaging for uncomplicated headache, 2.59%; 95% CI, 1.35% to 3.83%). Conclusions and Relevance: Two years into implementation, Oregon's and Colorado's Medicaid ACO models exhibited similar performance on standardized expenditures for selected services. Oregon's model, marked by a large federal investment and movement to global budgets, was associated with improvements in some measures of utilization, access, and quality, but Colorado's model paralleled Oregon's on several other metrics.
