Race-ethnicity and sex differences in 1-year survival following percutaneous coronary intervention among Medicare fee-for-service beneficiaries.

RATIONALE: Existing literature describing differences in survival following percutaneous coronary intervention (PCI) by patient sex, race-ethnicity and the role of socioeconomic characteristics (SEC) is limited. AIMS AND OBJECTIVES: Evaluate differences in 1-year survival after PCI by sex and race-ethnicity, and explore the contribution of SEC to observed differences. METHODS: Using a 20% sample of Medicare claims data for beneficiaries aged 65+, we identified fee-for-service patients who received PCI from 2007 to 2015. We performed logistic regression to assess how sex and race-ethnicity relate to procedural indication, inpatient versus outpatient setting, and 1-year mortality. We evaluated whether these relationships are moderated by sequentially controlling for factors including age, comorbidities, presence of acute myocardial infarction (AMI), county SEC, medical resource availability and inpatient versus outpatient procedural status. RESULTS: We identified 300,491 PCI procedures, of which 94,863 (31.6%) were outpatient. There was a significant transition to outpatient PCI during the study period, especially for men compared with women and White patients compared with Black patients. Black patients were 3.50 percentage points (p < 0.001) and women were 3.41 percentage points (p < 0.001) more likely than White and male patients to undergo PCI at the time of AMI, which typically occurs in the inpatient setting. Controlling for age and calendar year, Black patients were 2.87 percentage points more likely than non-Hispanic White patients to die within 1 year after PCI. After controlling for Black-White differences in comorbidities, the differences in 1-year mortality decreased to 0.95 percentage points, which then became nonsignificant when further controlling for county resources and state of residence. CONCLUSION: Women were more likely to experience PCI in the setting of AMI and had less transition to outpatient care during the period. Black patients experienced higher 1-year mortality following PCI, which is explained by differences in baseline comorbidities, county medical resources, and state of residence.

Attitudes Toward COVID-19 Vaccination Among Behavioral Health Service Clients.

OBJECTIVE: The authors examined attitudes toward and uptake of COVID-19 vaccination among individuals with serious mental illness or substance use disorder. METHODS: Clients of a community mental health center in Texas (N=50) participated in semistructured, in-person interviews regarding their COVID-19 vaccination decision. Thematic analysis was used to analyze interview data. RESULTS: Most participants (68%) reported receipt of at least one COVID-19 vaccine dose. Participants were motivated to get vaccinated mostly by a desire to protect themselves or others. Convenience of vaccination location and access to free vaccination facilitated vaccine uptake. However, concerns about the COVID-19 vaccine were common among both vaccinated and unvaccinated participants and could be reinforced or overcome by social network influences. CONCLUSIONS: Fear, uncertainty, and conflicting vaccine information were common themes in the COVID-19 vaccination decisions of behavioral health service clients. Improving access to information from trusted sources, including health care providers, could help to overcome vaccine concerns in this population.

Permanent Supportive Housing Receipt and Health Care Use Among Adults With Disabilities.

This study assessed whether permanent supportive housing (PSH) participation is associated with health service use among a population of adults with disabilities, including people transitioning into PSH from community and institutional settings. Our primary data sources were 2014 to 2018 secondary data from a PSH program in North Carolina linked to Medicaid claims. We used propensity score weighting to estimate the average treatment effect on the treated of PSH participation. All models were stratified by whether individuals were in institutional or community settings prior to PSH. In weighted analyses, among individuals who were institutionalized prior to PSH, PSH participation was associated with greater hospitalizations and emergency department (ED) visits and fewer primary care visits during the follow-up period, compared with similar individuals who largely remained institutionalized. Individuals who entered PSH from community settings did not have significantly different health service use from similar comparison group members during the 12-month follow-up period.

Enhanced Primary Care for People With Serious Mental Illness: A Propensity Weighted Cohort Study.

Objective: People with serious mental illness (SMI) have high rates of cardiometabolic illness, receive low quality care, and experience poor outcomes. Nevertheless, studies of existing integrated care models have not consistently shown improvements in cardiometabolic health for people with SMI. This study assessed the effect of a novel model of enhanced primary care for people with SMI on cardiometabolic outcomes. Enhanced primary care is a model of integrated care wherein comprehensive primary care delivery is adapted to the needs of people with SMI in coordination with behavioral care.Methods: We conducted a propensity-weighted cohort study comparing 234 patients with SMI receiving enhanced primary care to 4,934 patients with SMI receiving usual primary care using electronic health data from a large academic medical system covering the years 2014-2018. The propensity-weighted models controlled for baseline differences in outcome measures and patient characteristics between groups.Results: Compared to usual primary care, enhanced primary care increased hemoglobin A1c (HbA1c) screening by 18 percentage points (95% confidence interval [CI], 10 to 25), low-density lipoprotein (LDL) screening by 16 percentage points (CI, 8.8 to 24), and blood pressure screening by 7.8 percentage points (CI, 5.8 to 9.9). Enhanced primary care reduced HbA1c by 0.27 percentage points (CI, -0.47 to -0.060) and systolic blood pressure by 3.9 mm Hg (CI, -5.2 to -2.5) compared to usual primary care. We did not find evidence that enhanced primary care consistently affected glucose screening, LDL values, or diastolic blood pressure.Conclusions: Enhanced primary care can achieve clinically meaningful improvements in cardiometabolic health compared to usual primary care.

Permanent Supportive Housing Tenure Among a Heterogeneous Population of Adults with Disabilities.

People with disabilities can face substantial barriers to living stably in community settings. Evidence shows that permanent supportive housing (PSH), which combines subsidized housing with individualized support services, can improve housing stability among subpopulations of people with disabilities, including those with behavioral health conditions. PSH has also been shown to improve some health outcomes among people with severe mental illness or substance use disorder, but effects varied by participants' program tenure. This study assessed retention in a PSH program serving a broad population of adults with disabilities and identified factors associated with program tenure. Administrative data from 2093 individuals who began participating in a North Carolina PSH program between 2015 and 2018 were analyzed. Participants' unadjusted probability of remaining in a PSH placement at specific time points was estimated, with censoring due to death or the end of the study period (July 2020). Using Cox regression, program tenure was modeled as a function of participant and PSH placement location characteristics. Participants had a 71% probability of remaining in PSH after 2 years. Older age, female gender, and non-Hispanic Black race/ethnicity were associated with lower hazard of PSH departure. Having a severe mental illness diagnosis was associated with greater departure hazard. Level of socioeconomic deprivation and rurality of the PSH placement ZIP code were not associated with departure hazard. PSH programs may be able to successfully retain a heterogeneous population of adults with disabilities, although tenure may vary by participant demographic and clinical characteristics.

Are North Carolina clinicians delivering opioid use disorder treatment to Medicaid beneficiaries?

BACKGROUND AND AIMS: Medicaid is a public health insurance program in the United States that serves low-income individuals. Medicaid beneficiaries have elevated risk of opioid use disorder (OUD), yet face barriers to receiving medications for OUD (MOUD). To inform efforts to increase MOUD receipt among Medicaid beneficiaries, this study: (1) estimated Medicaid participation prevalence among clinicians authorized to prescribe buprenorphine and (2) estimated the association between clinician characteristics and OUD care delivery to Medicaid beneficiaries. DESIGN, SETTING AND PARTICIPANTS: Retrospective study of North Carolina, USA licensed physicians, physician assistants and nurse practitioners. Licensure data from 2018 were merged with 2019 US Drug Enforcement Administration (DEA) data to identify clinicians who received the DEA waiver required to prescribe buprenorphine (n = 1714). Medicaid claims data were used to characterize clinician engagement in OUD care delivery. MEASUREMENTS: Outcomes were indicators of any Medicaid professional claims and any Medicaid prescription claims for buprenorphine and/or naltrexone. Predictors included clinician characteristics (e.g. gender and race) and characteristics of clinicians' practice location (e.g. area opioid overdose death rate). FINDINGS: Most waivered clinicians delivered services to Medicaid beneficiaries, ranging from 67.0% of behavioral health clinicians to 82.9% of specialist physicians. Among waivered clinicians with Medicaid professional claims, prevalence of prescribing buprenorphine to Medicaid beneficiaries ranged from 30.3% among specialist physicians to 51.6% among behavioral health clinicians. The probability of prescribing MOUD to Medicaid beneficiaries was higher among waivered clinicians identifying as male compared with female (8.5 percentage points, P = 0.004) or black compared with white (9.9 percentage points, P = 0.007), older clinicians (0.5 percentage point increase per year, P < 0.001) and clinicians in counties with a higher opioid overdose death rate (5.0 percentage point increase per additional death per 10 000 residents, P = 0.010). CONCLUSIONS: Among clinicians in North Carolina, USA who are authorized to prescribe buprenorphine, 67-83% (depending on type of specialist) deliver services to Medicaid beneficiaries, but only 30-52% of those prescribe medications for opioid use disorder (OUD) to Medicaid beneficiaries. Engagement in OUD care delivery to Medicaid beneficiaries varies by clinician demographic and area characteristics.

Duration of medical home participation and quality of care for patients with chronic conditions.

OBJECTIVE: To examine whether the length of participation in a patient-centered medical home (PCMH), an evidence-based practice, leads to higher quality care for Medicaid enrollees with multiple co-morbid chronic conditions and major depressive disorder (MDD). DATA SOURCES: This analysis uses a unique data source that links North Carolina Medicaid claims and enrollment data with other administrative data including electronic records of state-funded mental health services, a state psychiatric hospital utilization database, and electronic records from a five-county behavioral health carve-out program. STUDY DESIGN: This retrospective cohort study uses generalized estimating equations (GEEs) on person-year-level observations to examine the association between the duration of PCMH participation and measures of guideline-concordant care, including the receipt of minimally adequate care for MDD, defined as 6 months of antidepressant use or eight psychotherapy visits each year. DATA COLLECTION/EXTRACTION METHODS: Adults with two or more chronic conditions reflected in administrative data, including MDD. PRINCIPAL FINDINGS: We found a 1.7 percentage point increase in the likelihood of receiving guideline-concordant care at 4 months of PCMH participation, as compared to newly enrolled individuals with a single month of participation (p < 0.05). This effect increased with each additional month of PCMH participation; 12 months of participation was associated with a 19.1 percentage point increase in the likelihood of receiving guideline-concordant care over a single month of participation (p < 0.01). CONCLUSIONS: The PCMH model is associated with higher quality of care for patients with multiple chronic conditions and MDD over time, and these benefits increase the longer a patient is enrolled. Providers and policy makers should consider the positive effect of increased contact with PCMHs when designing and evaluating initiatives to improve care for this population.

Effect of Enhanced Primary Care for People with Serious Mental Illness on Service Use and Screening.

BACKGROUND: Strategies are needed to better address the physical health needs of people with serious mental illness (SMI). Enhanced primary care for people with SMI has the potential to improve care of people with SMI, but evidence is lacking. OBJECTIVE: To examine the effect of a novel enhanced primary care model for people with SMI on service use and screening. DESIGN: Using North Carolina Medicaid claims data, we performed a retrospective cohort analysis comparing healthcare use and screening receipt of people with SMI newly receiving enhanced primary care to people with SMI newly receiving usual primary care. We used inverse probability of treatment weighting to estimate average differences in outcomes between the treatment and comparison groups adjusting for observed baseline characteristics. PARTICIPANTS: People with SMI newly receiving primary care in North Carolina. INTERVENTIONS: Enhanced primary care that includes features tailored for individuals with SMI. MAIN MEASURES: Outcome measures included outpatient visits, emergency department (ED) visits, inpatient stays and days, and recommended screenings 18 months after the initial primary care visit. KEY RESULTS: Compared to usual primary care, enhanced primary care was associated with an increase of 1.2 primary care visits (95% confidence interval [CI]: 0.31 to 2.1) in the 18 months after the initial visit and decreases of 0.33 non-psychiatric inpatient stays (CI: - 0.49 to - 0.16) and 3.0 non-psychiatric inpatient days (CI: - 5.3 to - 0.60). Enhanced primary care had no significant effect on psychiatric service and ED use. Enhanced primary care increased the probability of glucose and HIV screening, decreased the probability of lipid screening, and had no effect on hemoglobin A1c and colorectal cancer screening. CONCLUSIONS: Enhanced primary care for people with SMI can increase receipt of some preventive screening and decrease use of non-psychiatric inpatient care compared to usual primary care.

Medical home effects on enrollees with mental and physical illness.

OBJECTIVES: To assess the effect of medical home enrollment on acute care use and healthcare spending among Medicaid beneficiaries with mental and physical illness. STUDY DESIGN: Retrospective cohort analysis of administrative data. METHODS: We used 2007-2010 Medicaid claims and state psychiatric hospital data from a sample of 83,819 individuals diagnosed with schizophrenia or depression and at least 1 comorbid physical condition. We performed fixed-effects regression analysis at the person-month level to examine the effect of medical home enrollment on the probabilities of emergency department (ED) use, inpatient admission, and outpatient care use and on amount of Medicaid spending. RESULTS: Medical home enrollment had no effect on ED use in either cohort and was associated with a lower probability of inpatient admission in the depression cohort (P <.05). Medical home enrollees in both cohorts experienced an increase in the probability of having any outpatient visits (P <.05). Medical home enrollment was associated with an increase in mean monthly spending among those with schizophrenia ($65.8; P <.05) and a decrease among those with depression (-$66.4; P <.05). CONCLUSIONS: Among Medicaid beneficiaries with comorbid mental and physical illness, medical home enrollment appears to increase outpatient healthcare use and has mixed effects on acute care use. For individuals in this population who previously had no engagement with the healthcare system, use of the medical home model may represent an investment in providing improved access to needed outpatient services with cost savings potential for beneficiaries with depression.

Do Medical Homes Improve Quality of Care for Persons with Multiple Chronic Conditions?

OBJECTIVE: To examine the association between medical home enrollment and receipt of recommended care for Medicaid beneficiaries with multiple chronic conditions (MCC). DATA SOURCES/STUDY SETTING: Secondary claims data from fiscal years 2008-2010. The sample included nonelderly Medicaid beneficiaries with at least two of eight target conditions (asthma, chronic obstructive pulmonary disease, diabetes, hypertension, hyperlipidemia, seizure disorder, major depressive disorder, and schizophrenia). STUDY DESIGN: We used linear probability models with person- and year-level fixed effects to examine the association between patient-centered medical home (PCMH) enrollment and nine disease-specific quality-of-care metrics, controlling for selection bias and time-invariant differences between enrollees. DATA COLLECTION METHODS: This study uses a dataset that links Medicaid claims with other administrative data sources. PRINCIPAL FINDINGS: Patient-centered medical home enrollment was associated with an increased likelihood of receiving eight recommended mental and physical health services, including A1C testing for persons with diabetes, lipid profiles for persons with diabetes and/or hyperlipidemia, and psychotherapy for persons with major depression and persons with schizophrenia. PCMH enrollment was associated with overuse of short-acting ß-agonists among beneficiaries with asthma. CONCLUSIONS: The PCMH model can improve quality of care for patients with multiple chronic conditions.

Evaluating the potential for primary care to serve as a mental health home for people with schizophrenia.

OBJECTIVE: Primary care-based medical homes could improve the coordination of mental health care for individuals with schizophrenia and comorbid chronic conditions. The objective of this paper is to examine whether persons with schizophrenia and comorbid chronic conditions engage in primary care regularly, such that primary care settings have the potential to serve as a mental health home. METHOD: We examined the annual primary care and specialty mental health service utilization of adult North Carolina Medicaid enrollees with schizophrenia and at least one comorbid chronic condition who were in a medical home during 2007-2010. Using a fixed-effects regression approach, we also assessed the effect of medical home enrollment on utilization of primary care and specialty mental health care and medication adherence. RESULTS: A substantial majority (78.5%) of person-years had at least one primary care visit, and 17.9% had at least one primary care visit but no specialty mental health services use. Medical home enrollment was associated with increased use of primary care and specialty mental health care, as well as increased medication adherence. CONCLUSIONS: Medical home enrollees with schizophrenia and comorbid chronic conditions exhibited significant engagement in primary care, suggesting that primary-care-based medical homes could serve a care coordination function for persons with schizophrenia.
