Insurance type is associated with appropriate use of surgical and adjuvant care for differentiated thyroid carcinoma.

BACKGROUND: We aimed to characterize the association between differentiated thyroid cancer (DTC) patient insurance status and appropriateness of therapy (AOT) regarding extent of thyroidectomy and radioactive iodine (RAI) treatment. METHODS: The National Cancer Database was queried for DTC patients diagnosed between 2010 and 2016. Adjusted odds ratios (AOR) for AOT, as defined by the American Thyroid Association guidelines, and hazard ratios (HR) for overall survival (OS) were calculated. A difference-in-differences (DD) analysis examined the association of Medicaid expansion with outcomes for low-income patients aged <65. RESULTS: A total of 224,500 patients were included. Medicaid and uninsured patients were at increased risk of undergoing inappropriate therapy, including inappropriate lobectomy (Medicaid 1.36, 95% confidence interval [CI]: 1.21-1.54; uninsured 1.30, 95% CI: 1.05-1.60), and under-treatment with RAI (Medicaid 1.20, 95% CI: 1.14-1.26; uninsured 1.44, 95% CI: 1.33-1.55). Inappropriate lobectomy (HR 2.0, 95% CI: 1.7-2.3, P < .001) and under-treatment with RAI (HR 2.3, 95% CI: 2.2-2.5, P < .001) were independently associated with decreased survival, while appropriate surgical resection (HR 0.3, 95% CI: 0.3-0.3, P < .001) was associated with improved odds of survival; the model controlled for all relevant clinico-pathologic variables. No difference in AOT was observed in Medicaid expansion versus non-expansion states with respect to surgery or adjuvant RAI therapy. CONCLUSION: Medicaid and uninsured patients are at significantly increased odds of receiving inappropriate treatment for DTC; both groups are at a survival disadvantage compared with Medicare and those privately insured.

Association of medicaid expansion of the Affordable Care Act with the stage at diagnosis and treatment of papillary thyroid cancer: A difference-in-differences analysis.

BACKGROUND: The Affordable Care Act's (ACA) Medicaid expansion has increased insurance coverage and improved various cancer outcomes. Its impact in papillary thyroid cancer (PTC) remains unclear. METHODS: Non-elderly patients (40-64 years-old) with PTC living in low-income areas either in a 2014 expansion, or a non-expansion state were identified from the National Cancer Database between 2010 and 2016. Insurance coverage, stage at diagnosis, and RAI administration were analyzed using a difference-in-differences analysis. RESULTS: 10,644 patients were included. Compared with non-expansion states, the percentage of uninsured patients (adjusted-DD -2.6% [95%-CI -4.3to-0.8%],p = 0.004) and patients with private insurance decreased, and those with Medicaid coverage increased (adjusted-DD 9.7% [95%-CI 6.9-12.5%],p < 0.001) in expansion states after ACA implementation. The percentage of patients with pT1 did not differ between expansion and non-expansion states; neither did the use of RAI. CONCLUSIONS: Medicaid expansion has resulted in a smaller uninsured population in PTC patients, but without earlier disease presentation nor change in RAI treatment.

Impact of employment and insurance status on distress in gynecologic oncology patients.

OBJECTIVES: To study associations among employment, insurance status, and distress in gynecologic oncology patients; and to evaluate the impact of being unemployed or having no/Medicaid insurance on different distress problem areas. METHODS: In this single institution, cross-sectional analysis of gynecologic oncology patients, we screened for distress and problem areas using the National Comprehensive Cancer Network distress thermometer and problem list at outpatient appointments between 6/2017-9/2017. Primary outcome was self-reported high distress (score ≥ 5). The distress problem list included 5 categories-practical, family, emotional, physical, and other. Employment status included employed, unemployed, homemaker, and retired. Logistic regression was used to predict high distress from employment and insurance statuses, adjusting for relevant covariates. RESULTS: Of 885 women, 101 (11.4%) were unemployed, and 53 (6.0%) uninsured or had Medicaid coverage. One in five patients (n = 191, 21.6%) indicated high distress. Unemployed patients were more likely than employed to endorse high distress [adjusted odds ratio (aOR) = 3.5, 95% confidence interval (CI) 2.2-5.7, p < 0.001]. Compared to employed patients, a greater proportion of unemployed patients endorsed distress related to practical (p < 0.05), emotional (p < 0.001), physical (p < 0.01), and other (p < 0.05) problems. Uninsured/Medicaid patients were more likely to endorse high distress (aOR = 2.8, 95% CI 1.5-5.1, p < 0.001) and report family (p < 0.001), emotional (p < 0.001), and other (p < 0.01) problems than patients who had Medicare/commercial insurance. CONCLUSIONS: Gynecologic oncology patients who are unemployed or have no/Medicaid insurance face high distress that appears to arise from issues beyond practical problems, including financial and/or insurance insecurities.

Racial and ethnic disparities in care for health system-affiliated physician organizations and non-affiliated physician organizations.

OBJECTIVE: To assess racial and ethnic disparities in care for Medicare fee-for-service (FFS) beneficiaries and whether disparities differ between health system-affiliated physician organizations (POs) and nonaffiliated POs. DATA SOURCES: We used Medicare Data on Provider Practice and Specialty (MD-PPAS), Medicare Provider Enrollment, Chain, and Ownership System (PECOS), IRS Form 990, 100% Medicare FFS claims, and race/ethnicity estimated using the Medicare Bayesian Improved Surname Geocoding 2.0 algorithm. STUDY DESIGN: Using a sample of 16 007 POs providing primary care in 2015, we assessed racial/ethnic disparities on 12 measures derived from claims (2 cancer screenings; diabetic eye examinations; continuity of care; two medication adherence measures; three measures of follow-up visits after acute care; all-cause emergency department (ED) visits, all-cause readmissions, and ambulatory care-sensitive admissions). We decomposed these "total" disparities into within-PO and between-PO components using models with PO random effects. We then pair-matched 1853 of these POs that were affiliated with health systems to similar nonaffiliated POs. We examined differences in within-PO disparities by affiliation status by interacting each nonwhite race/ethnicity with an affiliation indicator. DATA COLLECTION/EXTRACTION METHODS: Medicare Data on Provider Practice and Specialty identified POs billing Medicare; PECOS and IRS Form 990 identified health system affiliations. Beneficiaries age 18 and older were attributed to POs using a plurality visit rule. PRINCIPAL FINDINGS: We observed total disparities in 12 of 36 comparisons between white and nonwhite beneficiaries; nonwhites received worse care in 10. Within-PO disparities exceeded between-PO disparities and were substantively important (>=5 percentage points or>=0.2 standardized differences) in nine of the 12 comparisons. Among these 12, nonaffiliated POs had smaller disparities than affiliated POs in two comparisons (P < .05): 1.6 percentage points smaller black-white disparities in follow-up after ED visits and 0.6 percentage points smaller Hispanic-white disparities in breast cancer screening. CONCLUSIONS: We find no evidence that system-affiliated POs have smaller racial and ethnic disparities than nonaffiliated POs. Where differences existed, disparities were slightly larger in affiliated POs.

Disparities in outpatient visits for mental health and/or substance use disorders during the COVID surge and partial reopening in Massachusetts.

OBJECTIVE: To examine changes in outpatient visits for mental health and/or substance use disorders (MH/SUD) in an integrated healthcare organization during the initial Massachusetts COVID-19 surge and partial state reopening. METHODS: Observational study of outpatient MH/SUD visits January 1st-June 30th, 2018-2020 by: 1) visit diagnosis group, 2) provider type, 3) patient race/ethnicity, 4) insurance, and 5) visit method (telemedicine vs. in-person). RESULTS: Each year, January-June 52,907-73,184 patients were seen for a MH/SUD visit. While non-MH/SUD visits declined during the surge relative to 2020 pre-pandemic (-38.2%), MH/SUD visits increased (9.1%)-concentrated in primary care (35.3%) and non-Hispanic Whites (10.5%). During the surge, MH visit volume increased 11.7% while SUD decreased 12.7%. During partial reopening, while MH visits returned to 2020 pre-pandemic levels, SUD visits declined 31.1%; MH/SUD visits decreased by Hispanics (-33.0%) and non-Hispanic Blacks (-24.6%), and among Medicaid (-19.4%) and Medicare enrollees (-20.9%). Telemedicine accounted for ~5% of MH/SUD visits pre-pandemic and 83.3%-83.5% since the surge. CONCLUSIONS: MH/SUD visit volume increased during the COVID surge and was supported by rapidly-scaled telemedicine. Despite this, widening diagnostic and racial/ethnic disparities in MH/SUD visit volume during the surge and reopening suggest additional barriers for these vulnerable populations, and warrant continued monitoring and research.

Validation of algorithms to estimate gestational age at birth in the Medicaid Analytic eXtract-Quantifying the misclassification of maternal drug exposure during pregnancy.

PURPOSE: Accurate ascertainment of gestational age (GA) has been a challenge in perinatal epidemiologic research. To date, no study has validated GA algorithms in Medicaid Analytic eXtract (MAX). METHODS: We linked livebirths of mothers enrolled in Medicaid ≥30 days after delivery in 1999-2010 MAX to state birth certificates. We used clinical/obstetric estimate of gestation on the birth certificates as gold standard to validate claims-based GA algorithms. We calculated the proportions of deliveries with algorithm-estimated GA within 1-/2-weeks of the gold standard, the sensitivity, specificity, and positive/negative predictive value (PPV/NPV) of exposure to select medications during specific gestation windows, and quantified the impact of exposure misclassification on hypothetical relative risk (RR) estimates. RESULTS: We linked 1 336 495 eligible deliveries. Within 1-week agreement was 77%-80% overall and 47%-56% for preterm deliveries. The trimester-specific drug exposure status had high sensitivities and PPVs (88.5%-98.5%), and specificities and NPVs (>99.0%). Assuming a hypothetical RR of 2.0, bias associated with exposure misclassification during first trimester ranged from 10% to 40% under non-differential/differential misclassification assumptions. CONCLUSIONS: Claims-based GA algorithms had good agreement with the gold standard overall, but lower agreement among preterm deliveries, potentially resulting in biased risk estimated for pregnancy exposure evaluations.

Prenatal Depression: Assessment and Outcomes among Medicaid Participants.

This study used bivariate and regression-adjusted analyses of participant-level survey and medical data to investigate prevalence of depression among pregnant Medicaid participants, correlates of depression, and the relationship between depression and pregnancy outcomes. The sample included Medicaid participants with a single gestation and valid depression data who were enrolled in Strong Start for Mothers and Newborns 2, a national preterm birth prevention program, from 2013 to 2017 (N = 37,287; 85% of total enrollment). Depression rates in Strong Start were high (27.5%). Depression was associated with being black; having other children, an unplanned pregnancy, or challenges accessing prenatal care; not having a co-resident spouse or partner; and experiencing intimate partner violence. After these and other risk factors were controlled for, depression remained associated with higher rates of preterm birth. Systematic screening and holistic approaches to prenatal care that address depression and associated risks could help reduce rates of preterm birth and other poor pregnancy outcomes.

The effects of the Maryland Medicaid Health Home Waiver on Emergency Department and inpatient utilization among individuals with serious mental illness.

OBJECTIVE: The Maryland Medicaid health home program, established through the Affordable Care Act's Medicaid health home waiver, integrates primary care services into specialty mental health programs for adults with serious mental illness (SMI). We evaluated the effect of this program on all-cause, physical, and behavioral health emergency department (ED) and inpatient utilization. METHOD: Using marginal structural modeling to control for time-invariant and time-varying confounding, we analyzed Medicaid administrative claims data for 12,232 enrollees with SMI from October 1, 2012 to December 31, 2016; 3319 individuals were enrolled in a BHH and 8913 were never enrolled. RESULTS: Health home enrollment was associated with reduced probability of all-cause (PP: 0.23 BHH enrollment vs. 0.26 non-enrollment, p < 0.01) and physical health ED visits (PP: 0.21 BHH enrollment vs. 0.24 non-enrollment, p < 0.01) and no effect on inpatient admissions per person-three-month period. CONCLUSION: These results suggest the Maryland Medicaid health home waiver's focus on supporting physical health care coordination by specialty mental health programs may be preventing ED visits among adults with SMI, although effect sizes are small.

Insurance Differences in Preventive Care Use and Adverse Birth Outcomes Among Pregnant Women in a Medicaid Nonexpansion State: A Retrospective Cohort Study.

Background: Lack of quality preventive care has been associated with poorer outcomes for pregnant women with low incomes. Health policy changes implemented with the Affordable Care Act (ACA) were designed to improve access to care. However, insurance coverage remains lower among women in Medicaid nonexpansion states. We compared health care use and adverse birth outcomes by insurance status among women giving birth in a large health system in a Medicaid nonexpansion state. Materials and Methods: We conducted a population-based retrospective cohort study using data for 9,613 women with deliveries during 2014-2015 at six hospitals associated with a large vertically integrated health care system in North Carolina. Adjusted logistic regression and zero-inflated negative binomial models examined associations between insurance status at delivery (commercial, Medicaid, or uninsured) and health care utilization (well-woman visits, late prenatal care, adequacy of prenatal care, postpartum follow-up, and emergency department [ED] visits) and outcomes (preterm birth, low birth weight, preeclampsia, and gestational diabetes). Results: Having Medicaid at delivery was associated with lower rates of well-woman visits (rate ratio [RR] 0.25, 95% CI 0.23-0.28), higher rates of ED visits (RR 2.93, 95% CI 2.64-3.25), and higher odds of late prenatal care (odds ratio [OR] 1.18, 95% CI 1.03-1.34) compared to having commercial insurance, with similar results for uninsured women. Differences in adverse pregnancy outcomes were not statistically significant after adjusting for patient characteristics. Conclusions: Findings suggest that large gaps exist in use of preventive care between Medicaid/uninsured and commercially insured women. Policymakers should consider ways to improve potential and realized access to care.

The effects of integrating behavioral health into primary care for low-income children.

OBJECTIVE: To evaluate the impact of TEAM UP-an initiative that fully integrates behavioral health services into pediatric primary care in three Boston-area Community Health Centers (CHCs)-on health care utilization and costs. DATA SOURCES: 2014-2017 claims data on continuously enrolled children from a Massachusetts Medicaid managed care plan. STUDY DESIGN: We used a difference-in-difference approach with inverse probability of treatment weights to compare outcomes in children receiving primary care at TEAM UP CHCs versus comparison site CHCs, in the pre (2014-2016q2)- versus post (2016q3-2017)-intervention periods. Utilization outcomes included emergency department visits, inpatient admissions, primary care visits, and outpatient/professional visits (all cause and those with mental health (MH) diagnoses). Cost outcomes included total cost of care (inpatient, outpatient, professional, pharmacy). We further assessed differential effects by baseline MH diagnosis. PRINCIPAL FINDINGS: After 1.5 years, TEAM UP was associated with a relative increase in the rate of primary care visits (IRR = 1.15, 95% CI 1.04-1.27, or 115 additional visits/1000 patients/quarter), driven by children with a MH diagnosis at baseline. There was no significant change in avoidable health care utilization or cost. CONCLUSIONS: Expanding the TEAM UP behavioral health integration model to other sites has the potential to improve primary care engagement in low-income children with MH needs.

A Successful Walk-In Psychiatric Model for Integrated Care.

PURPOSE: Accommodating walk-in psychiatry visits in primary care can improve access to psychiatric care for patients from historically underserved groups. We sought to determine whether a walk-in psychiatry model embedded within an integrated care practice could be sustained over time, and to characterize the patients who accessed care through it. METHODS: We reviewed electronic health records linked to 811 psychiatry encounters in an integrated care practice between October 1, 2015 and September 30, 2017. Primary outcomes were the initial and return psychiatry encounters per month. Secondary outcomes were the demographics and diagnoses of patients who accessed their initial visits through walk-in sessions and scheduled appointments. RESULTS: 490 initial psychiatry evaluations and 321 return encounters took place over the 2-year study period. The volume of initial psychiatry evaluations per month did not significantly change, but the volume of psychiatry follow-up encounters significantly increased after the walk-in session expanded. Medicaid recipients (OR, 1.9; 95% CI, 1.2 to 3.0); individuals without a college degree (OR, 1.7; 95% CI, 1.1 to 2.5); individuals who were single, divorced, or separated (OR, 1.7; 95% CI, 1.1 to 2.5); and individuals who identified as Black or Hispanic (OR, 2.5; 95% CI, 1.7 to 3.6) were more likely to access an initial psychiatry evaluation through a walk-in session as opposed to a scheduled appointment. CONCLUSIONS: Providing psychiatric care on a walk-in basis in integrated care is sustainable. Patients from historically underserved groups may access psychiatric care disproportionately through a walk-in option when it is available.

Disparity in the use of adjuvant radioactive iodine ablation among high-risk papillary thyroid cancer patients.

BACKGROUND: We sought to identify treatment disparities existing prior to publication of the 2015 American Thyroid Association Management Guidelines in order to identify patients with papillary thyroid cancer (PTC) at risk for receiving inadequate treatment. METHODS: Patients diagnosed with PTC from 2011 to 2013 were identified using Surveillance, Epidemiology and End Results database. High-risk disease was defined as T4, N1, or M1. Chi-square tests compared characteristics of patients with and without high-risk disease and characteristics of high-risk patients who did and did not receive radioactive iodine ablation (RAI). Likelihoods of having high-risk disease, of receiving RAI, and of cause-specific death were calculated using regression analyses. RESULTS: Sample included 32,229 individuals; 7894 (24.5%) had high-risk disease. Mean age was 50.0 years, 24,815 (77.0%) were female, and 21,318 (66.2%) were white. Odds of high-risk disease were greater among males (OR:2.04; 95% CI:1.92-2.16), Hispanics (OR:1.67; 95% CI:1.56-1.79) and Asians (OR:1.49; 95% CI:1.37-1.62), and uninsured (OR:1.24; 95% CI:1.07-1.43), and lower among patients ages 45-64 (OR:0.57; 95% CI:0.53-0.60), and ≥65 years (OR:0.54; 95% CI:0.50-0.59), and Blacks (OR:0.46; 95% CI:0.40-0.53). Most (69.3%) high-risk patients received RAI. Odds of receiving RAI were lower among patients age ≥65 years (OR:0.67; 95% CI:0.58-0.77), uninsured (OR:0.52; 95% CI:0.41-0.67), or with Medicaid (OR:0.58; 95% CI:0.50-0.69). RAI use reduced the risk of cause-specific mortality (HR:0.29; 95% CI:0.18-0.47). CONCLUSION: Knowledge of these treatment disparities will allow recognition of groups at risk for high-risk disease and receiving inadequate treatment.

Promoting health payment reform literacy: Does integrated care save money?

INTRODUCTION: Under the current payment environment, the challenges to implementing and sustaining integrated behavioral health care are substantial. One key barrier for clinicians, administrators, researchers, and patients/families is a lack of clarity about who pays for integrated health care in the United States, and a lack of consensus about whether bending the health care cost curve is a fundamental goal of integrated care, and for whom. Clinicians caring for patients and families in integrated care settings would benefit from honing their "payment reform literacy skills" in order to advocate for integrated care. METHOD: This paper offers a primer on the current state of health care spending in the United States, an overview of public and private payers, and the challenges each faces in paying for integrated care. DISCUSSION: Future journal articles in the FSH Policy and Management Department will describe key payment policy and management opportunities for integrated care payment reform.

Identifying disparities in germline and somatic testing for ovarian cancer.

OBJECTIVE: Germline mutations occur in approximately 25% of patients with epithelial ovarian cancers while somatic BRCA mutations are estimated at 5-7%. The objectives of this study were to determine the rate of germline and somatic testing in women with ovarian cancer and to identify disparities in testing at a comprehensive cancer center (CCC) and a safety net hospital (SNH). METHODS: Patients treated for ovarian cancer from 2011 to 2016 were included. Clinicopathologic data were abstracted from the electronic medical records. Logistic regression modeling were performed to calculate odds ratios (OR) and corresponding 95% confidence intervals (95%CI). RESULTS: Out of 367 women, 55.3% completed germline testing; 27.0% received somatic testing. Women at the CCC were more likely to be tested for germline (60.4% vs 38.1%, p ≤ 0.001) and somatic (34.3% vs 2.4%, p ≤ 0.001) mutations than those at the SNH. Patients with Medicare (aOR = 0.51, 95%CI 0.28-0.94, p = 0.032) or Medicaid (aOR = 0.42, 95%CI 0.18-0.99, p = 0.048) were less likely to receive germline testing than those privately insured. Patients with Medicaid were less likely to receive somatic testing (aOR = 0.15, 95%CI 0.04-0.62, p = 0.009) than those privately insured. Women with disease recurrence had a higher likelihood of being tested for germline (OR = 3.64, 95%CI 1.94-6.83, P < 0.001) and somatic (OR = 7.89, 95%CI 3.41-18.23, p < 0.001) mutations. There was no difference in germline or somatic testing by race/ethnicity. CONCLUSIONS: Disparities in both germline and somatic testing exist. Understanding and overcoming barriers to testing may improve cancer-related mortality by allowing for more tailored treatments as well as for improved cascade testing.

Outdoor temperature and survival benefit of empiric potassium in users of furosemide in US Medicaid enrollees: a cohort study.

OBJECTIVE: Heat is associated with elevated all-cause mortality, and furosemide-induced potassium depletion might be worsened by heat-induced sweating. Because empiric potassium is associated with a marked survival benefit in users of furosemide at a dose of ≥40 mg/day, we hypothesised that this empiric potassium's survival benefit would increase with higher temperature (≥24°C). DESIGN: Cohort study. SETTING: Outpatient setting, captured by Medicaid claims, supplemented with Medicare claims for dual enrollees, from 5 US states from 1999 to 2010, linked to meteorological data. POPULATION/PARTICIPANTS: Furosemide (≥40 mg/day) initiators among adults continuously enrolled in Medicaid for at least 1 year prior to cohort entry (defined as the day following the dispensing day of each individual's first observed furosemide prescription). EXPOSURE: Interaction between: (1) empiric potassium, dispensed the day of or the day following the dispensing of the initial furosemide prescription, and (2) daily average temperature and daily maximum temperature, examined separately. OUTCOME: All-cause mortality. RESULTS: In 1:1 propensity score matched cohorts (total n=211 878) that included 89 335 person-years and 9007 deaths, all-cause mortality rates per 1000 person-years were 96.0 (95% CI 93.2 to 98.9) and 105.8 (95% CI 102.8 to 108.9) for potassium users and non-users, respectively. The adjusted OR of all-cause mortality for potassium use declined (ie, its apparent protective effect increased) as temperature increased, from a daily average temperature of about 28°C and a daily maximum temperature of about 31°C. This relationship was not statistically significant with daily average temperature, but was statistically significant with daily maximum temperature (p values for the interaction of potassium with daily maximum temperature and daily maximum temperature squared were 0.031 and 0.028, respectively). CONCLUSIONS: The results suggest that empiric potassium's survival benefit among furosemide (≥40 mg/day) initiators may increase as daily maximum temperature increases. If this relationship is real, use of empiric potassium in Medicaid enrollees initiating furosemide might be particularly important on hot days.

Association Between Maternal 2nd Trimester Plasma Folate Levels and Infant Bronchiolitis.

Objectives Viral bronchiolitis is the most common cause of infant hospitalization. Folic acid supplementation is important during the periconceptional period to prevent neural tube defects. An area of investigation is whether higher prenatal folate is a risk factor for childhood respiratory illnesses. We investigated the association between maternal 2nd trimester plasma folate levels and infant bronchiolitis. Methods We conducted a retrospective cohort analysis in a subset of mother-infant dyads (n = 676) enrolled in the Conditions Affecting Neurocognitive Development and Learning in Early Childhood study and Tennessee Medicaid. Maternal folate status was determined using 2nd trimester (16-28 weeks) plasma samples. Bronchiolitis diagnosis in the first year of life was ascertained using International Classification of Diagnosis-9 codes from Medicaid administrative data. We used multivariable logistic regression to assess the adjusted association of prenatal folate levels and infant bronchiolitis outcome. Results Half of the women in this lower-income and predominately African-American (84%) study population had high levels of folate (median 2nd trimester level 19.2 ng/mL) and 21% of infants had at least one bronchiolitis healthcare visit. A relationship initially positive then reversing between maternal plasma folate and infant bronchiolitis was observed that did not reach statistical significance (poverall = .112, pnonlinear effect = .088). Additional adjustment for dietary methyl donor intake did not significantly alter the association. Conclusions for Practice Results did not confirm a statistically significant association between maternal 2nd trimester plasma folate levels and infant bronchiolitis. Further work is needed to investigate the role of folate, particularly higher levels, in association with early childhood respiratory illnesses.

Racial and ethnic differences in mental health service utilization among the Hawaii medicaid population.

Background: Racial/ethnic differences have not been adequately addressed in the utilization of mental health services among Medicaid populations. Aim: This study aimed to examine racial/ethnic differences in the utilization of health services for mental disorders in a Medicaid adult population aged between 21 and 64 years. Methods: Racial/ethnic differences in inpatient, outpatient and emergency department services utilization were assessed using 2010 Hawaii Medicaid data. Zero-inflated negative binomial regressions were employed adjusting for age, sex and residential area. Results: Among 73,200 beneficiaries, 29.7% were Whites, 28.5% Asians, 34.7% Native Hawaiians and Pacific Islanders (NHPIs); 60.2% were younger (21-44 years) and 58.6% were females. The patterns of utilization of health services differed across race/ethnicity. Compared to Whites, Asians and NHPIs were less likely to use outpatient services and had lower rates of inpatient visits. NHPIs were also estimated to have lower rates of outpatient and emergency department visits. Conclusion: Variation in the utilization of health services emphasizes the importance of race/ethnicity in mental health management. Various factors, such as language barriers and cultural differences, should be considered in developing clinical interventions or integrative health programs that aim to reduce racial/ethnic disparities among people with mental disorders.

Behavioral Health's Integration Within a Care Network and Health Care Utilization.

OBJECTIVE: Examine how behavioral health (BH) integration affects health care costs, emergency department (ED) visits, and inpatient admissions. DATA SOURCES/STUDY SETTING: Truven Health MarketScan Research Databases. STUDY DESIGN: Social network analysis identified "care communities" (providers sharing a high number of patients) and measured BH integration in terms of how connected, or central, BH providers were to other providers in their community. Multivariable generalized linear models adjusting for age, sex, number of prescriptions, and Charlson comorbidity score were used to estimate the relationship between the centrality of BH providers and health care utilization of BH patients. DATA COLLECTION/EXTRACTION METHODS: Used outpatient, inpatient, and pharmacy claims data from six Medicaid plans from 2011 to 2013 to identify study outcomes, comorbidities, providers, and health care encounters. PRINCIPAL FINDINGS: Behavioral health centrality ranged from 0 (no BH providers) to 0.49. Relative to communities at the median BH centrality (0.06), in 2012, BH patients in communities at the 75th percentile of BH centrality (0.31) had 0.2 fewer admissions, 2.1 fewer all-cause ED visits, and accrued $1,947 fewer costs, on average. CONCLUSIONS: Increased behavioral centrality was significantly associated with a reduced number of ED visits, less frequent inpatient admissions, and lower overall health care costs.

Disparities in Adherence to National Comprehensive Cancer Network Treatment Guidelines and Survival for Stage IB-IIA Cervical Cancer in California.

OBJECTIVE: To evaluate the association of sociodemographic and hospital characteristics with adherence to National Comprehensive Cancer Network treatment guidelines for stage IB-IIA cervical cancer and to analyze the relationship between adherent care and survival. METHODS: This is a retrospective population-based cohort study of patients with stage IB-IIA invasive cervical cancer reported to the California Cancer Registry from January 1, 1995, through December 31, 2009. Adherence to National Comprehensive Cancer Network guideline care was defined by year- and stage-appropriate surgical procedures, radiation, and chemotherapy. Multivariate logistic regression, Kaplan-Meier estimate, and Cox proportional hazard models were used to examine associations between patient, tumor, and treatment characteristics and National Comprehensive Cancer Network guideline adherence and cervical cancer-specific 5-year survival. RESULTS: A total of 6,063 patients were identified. Forty-seven percent received National Comprehensive Cancer Network guideline-adherent care, and 18.8% were treated in high-volume centers (20 or more patients/year). On multivariate analysis, lowest socioeconomic status (adjusted odds ratio [OR] 0.69, 95% CI 0.57-0.84), low-middle socioeconomic status (adjusted OR 0.76, 95% CI 0.64-0.92), and Charlson-Deyo comorbidity score 1 or higher (adjusted OR 0.78, 95% CI 0.69-0.89) were patient characteristics associated with receipt of nonguideline care. Receiving adherent care was less common in low-volume centers (45.9%) than in high-volume centers (50.9%) (effect size 0.90, 95% CI 0.84-0.96). Death from cervical cancer was more common in the nonadherent group (13.3%) than in the adherent group (8.6%) (effect size 1.55, 95% CI 1.34-1.80). Black race (adjusted hazard ratio 1.56, 95% CI 1.08-2.27), Medicaid payer status (adjusted hazard ratio 1.47, 95% CI 1.15-1.87), and Charlson-Deyo comorbidity score 1 or higher (adjusted hazard ratio 2.07, 95% CI 1.68-2.56) were all associated with increased risk of dying from cervical cancer. CONCLUSION: Among patients with early-stage cervical cancer, National Comprehensive Cancer Network guideline-nonadherent care was independently associated with increased cervical cancer-specific mortality along with black race and Medicaid payer status. Nonadherence was more prevalent in patients with older age, lower socioeconomic status, and receipt of care in low-volume centers. Attention should be paid to increase guideline adherence.

Association of Medical and Adult-Use Marijuana Laws With Opioid Prescribing for Medicaid Enrollees.

Importance: Overprescribing of opioids is considered a major driving force behind the opioid epidemic in the United States. Marijuana is one of the potential nonopioid alternatives that can relieve pain at a relatively lower risk of addiction and virtually no risk of overdose. Marijuana liberalization, including medical and adult-use marijuana laws, has made marijuana available to more Americans. Objective: To examine the association of state implementation of medical and adult-use marijuana laws with opioid prescribing rates and spending among Medicaid enrollees. Design, Setting, and Participants: This cross-sectional study used a quasi-experimental difference-in-differences design comparing opioid prescribing trends between states that started to implement medical and adult-use marijuana laws between 2011 and 2016 and the remaining states. This population-based study across the United States included all Medicaid fee-for-service and managed care enrollees, a high-risk population for chronic pain, opioid use disorder, and opioid overdose. Exposures: State implementation of medical and adult-use marijuana laws from 2011 to 2016. Main Outcomes and Measures: Opioid prescribing rate, measured as the number of opioid prescriptions covered by Medicaid on a quarterly, per-1000-Medicaid-enrollee basis. Results: State implementation of medical marijuana laws was associated with a 5.88% lower rate of opioid prescribing (95% CI, -11.55% to approximately -0.21%). Moreover, the implementation of adult-use marijuana laws, which all occurred in states with existing medical marijuana laws, was associated with a 6.38% lower rate of opioid prescribing (95% CI, -12.20% to approximately -0.56%). Conclusions and Relevance: The potential of marijuana liberalization to reduce the use and consequences of prescription opioids among Medicaid enrollees deserves consideration during the policy discussions about marijuana reform and the opioid epidemic.
