Medication-assisted treatment for substance use disorders within a national community health center research network

Alcohol Treatment Access and Engagement Among Women in the USA: a Targeted Review of the Literature 2012-2022

Purpose of Review

The purpose of this review is to examine recent literature (2012-2022) on alcohol treatment access and engagement in women in the U.S. and propose future directions for research and clinical practice.

Recent Findings

A targeted literature review resulted in 27 studies encompassing screening and brief intervention (SBIRT), treatment utilization, treatment engagement, and barriers to treatment. Recent literature demonstrates overall low rates of screening and brief interventions and treatment utilization in the population with women less likely to be screened and utilize alcohol treatment. The magnitude of these gender differences varies with race/ethnicity. Extensive barriers to care include provider knowledge, structural barriers, and attitudinal barriers and these vary with service setting, gender, and race/ethnicity.

Summary

There is an increasing prevalence of alcohol use and Alcohol Use Disorder (AUD) in women with low rates of screening, brief treatment, treatment, and engagement which have resulted from extensive barriers to care. Possible areas of further inquiry include the impact of race/ethnicity on gender differences, improving provider and system level policies to promote SBIRT and treatment engagement and utilization, further developing digital interventions, and implementation research to investigate factors associated with optimizing effectiveness of gender-responsive and culturally tailored interventions that address the unique needs of women.

Medications for alcohol use disorder improve survival in patients with hazardous drinking and alcohol-associated cirrhosis

BACKGROUND

Medications for alcohol use disorder (MAUD) are highly effective in achieving and maintaining abstinence in patients with alcohol use disorder (AUD). Our aim was to evaluate the effect of MAUD on all-cause mortality in patients with alcohol-associated cirrhosis and active alcohol use.

METHODS

This was a retrospective cohort study of patients with alcohol-associated cirrhosis and high-risk alcohol use disorder in the Veterans Outcomes and Costs Associated with Liver Disease (VOCAL) database. Propensity score matching for exposure to MAUD (acamprosate or naltrexone) within a year after cirrhosis diagnosis was performed to account for potential confounders, and the association between MAUD and all-cause mortality was subsequently evaluated using Cox regression analysis.

RESULTS

A total of 9131 patients were included, of whom 886 (9.7%) were exposed to MAUD (naltrexone: 520, acamprosate: 307, both medications: 59). The duration of MAUD exposure was >3 months in 345 patients (39%). The strongest positive predictor of MAUD prescription was an inpatient diagnosis code for AUD, followed by a concurrent diagnosis of depression; the strongest negative predictor was a history of cirrhosis decompensation. After propensity score matching (866 patients in each group) with excellent covariate balance (absolute standardized mean differences <0.1), MAUD exposure was associated with improved survival, with an HR of 0.80 relative to no MAUD exposure (95% CI: 0.67-0.97, p = 0.024).

CONCLUSION

MAUD are underutilized in patients with alcohol-associated cirrhosis with high-risk alcohol use behavior but are associated with improved survival after adjustment for confounders such as the severity of liver disease, age, and engagement in the healthcare system.

Novel digital approaches to the assessment of problematic opioid use

The opioid epidemic continues to contribute to loss of life through overdose and significant social and economic burdens. Many individuals who develop problematic opioid use (POU) do so after being exposed to prescribed opioid analgesics. Therefore, it is important to accurately identify and classify risk factors for POU. In this review, we discuss the etiology of POU and highlight novel approaches to identifying its risk factors. These approaches include the application of polygenic risk scores (PRS) and diverse machine learning (ML) algorithms used in tandem with data from electronic health records (EHR), clinical notes, patient demographics, and digital footprints. The implementation and synergy of these types of data and approaches can greatly assist in reducing the incidence of POU and opioid-related mortality by increasing the knowledge base of patient-related risk factors, which can help to improve prescribing practices for opioid analgesics.

Practical Assessment of Alcohol Use Disorder in Routine Primary Care: Performance of an Alcohol Symptom Checklist

BACKGROUND

Alcohol use disorder (AUD) is highly prevalent but underrecognized and undertreated in primary care settings. Alcohol Symptom Checklists can engage patients and providers in discussions of AUD-related care. However, the performance of Alcohol Symptom Checklists when they are used in routine care and documented in electronic health records (EHRs) remains unevaluated.

OBJECTIVE

To evaluate the psychometric performance of an Alcohol Symptom Checklist in routine primary care.

DESIGN

Cross-sectional study using item response theory (IRT) and differential item functioning analyses of measurement consistency across age, sex, race, and ethnicity.

PATIENTS

Patients seen in primary care in the Kaiser Permanente Washington Healthcare System who reported high-risk drinking on the Alcohol Use Disorder Identification Test Consumption screening measure (AUDIT-C ≥ 7) and subsequently completed an Alcohol Symptom Checklist between October 2015 and February 2020.

MAIN MEASURE

Alcohol Symptom Checklists with 11 items assessing AUD criteria defined in the Diagnostic and Statistical Manual for Mental Disorders, 5th edition (DSM-5), completed by patients during routine medical care and documented in EHRs.

KEY RESULTS

Among 11,464 patients who screened positive for high-risk drinking and completed an Alcohol Symptom Checklist (mean age 43.6 years, 30.5% female), 54.1% reported ≥ 2 DSM-5 AUD criteria (threshold for AUD diagnosis). IRT analyses demonstrated that checklist items measured a unidimensional continuum of AUD severity. Differential item functioning was observed for some demographic subgroups but had minimal impact on accurate measurement of AUD severity, with differences between demographic subgroups attributable to differential item functioning never exceeding 0.42 points of the total symptom count (of a possible range of 0-11).

CONCLUSIONS

Alcohol Symptom Checklists used in routine care discriminated AUD severity consistently with current definitions of AUD and performed equitably across age, sex, race, and ethnicity. Integrating symptom checklists into routine care may help inform clinical decision-making around diagnosing and managing AUD.

Practical assessment of DSM-5 alcohol use disorder criteria in routine care: High test-retest reliability of an Alcohol Symptom Checklist

BACKGROUND

Alcohol use disorder (AUD) is underdiagnosed and undertreated in medical settings, in part due to a lack of AUD assessment instruments that are reliable and practical for use in routine care. This study evaluates the test-retest reliability of a patient-report Alcohol Symptom Checklist questionnaire when it is used in routine care, including primary care and mental health specialty settings.

METHODS

We performed a pragmatic test-retest reliability study using electronic health record (EHR) data from Kaiser Permanente Washington, an integrated health system in Washington state. The sample included 454 patients who reported high-risk drinking on a behavioral health screen and completed two Alcohol Symptom Checklists 1 to 21 days apart. Subgroups of these patients who completed both checklists in primary care (n = 271) or mental health settings (n = 79) were also examined. The primary measure was an Alcohol Symptom Checklist on which patients self-reported whether they experienced each of the 11 AUD criteria within the past year, as defined by the Diagnostic and Statistical Manual of Mental Disorders-5^th edition (DSM-5).

RESULTS

Alcohol Symptom Checklists completed in routine care and documented in EHRs had excellent test-retest reliability for measuring AUD criterion counts (ICC = 0.79, 95% CI: 0.76 to 0.82). Test-retest reliability estimates were also high and not significantly different for the subsamples of patients who completed both checklists in primary care (ICC = 0.82, 95% CI: 0.77 to 0.85) or mental health settings (ICC = 0.74, 95% CI: 0.62 to 0.83). Test-retest reliability was not moderated by having a past two-year AUD diagnosis, nor by the age or sex of the patient completing it.

CONCLUSIONS

Alcohol Symptom Checklists can reliably and pragmatically assess AUD criteria in routine care among patients who screen positive for high-risk drinking. The Alcohol Symptom Checklist may be a valuable tool in supporting AUD-related care and monitoring AUD criteria longitudinally in routine primary care and mental health settings.

Collaborative health systems ECHO: The use of a tele-education platform to facilitate communication and collaboration with recipients of state targeted response funds in Pennsylvania

Background: The opioid epidemic continues to erode communities across Pennsylvania (PA). Federal and PA state programs developed grants to establish Hub and Spoke programs for the expansion of medications for opioid use disorders (MOUD). Employing the telementoring platform Project ECHO (Extension for Community Health Outcomes), Penn State Health engaged the other seven grant awardees in a Collaborative Health Systems (CHS) ECHO. We conducted key informant interviews to better understand impact of the CHS ECHO on health systems collaboration and opioid crisis efforts. Methods: For eight one-hour sessions, each awardee presented their unique strategies, challenges, and opportunities. Using REDCap, program characteristics, such as number of waivered prescribers and number of patients served were collected at baseline. After completion of the sessions, key informant interviews were conducted to assess the impact of CHS ECHO on awardee's programs. Results: Analysis of key informant interviews revealed important themes to address opioid crisis efforts, including the need for strategic and proactive program reevaluation and the convenience of collaborative peer learning networks. Participants expressed benefits of the CHS ECHO including allowing space for discussion of challenges and best practices and facilitating conversation on collaborative targeted advocacy and systems-level improvements. Participants further reported bolstered motivation and confidence. Conclusions: Utilizing Project ECHO provided a bidirectional platform of learning and support that created important connections between institutions working to combat the opioid epidemic. CHS ECHO was a unique opportunity for productive and convenient peer learning across external partners. Open dialogue developed during CHS ECHO can continue to direct systems-levels improvements that benefit individual and population outcomes.

Documented opioid use disorder and its treatment in primary care patients across six U.S. health systems

BACKGROUND

The United States is in the middle of an opioid overdose epidemic, and experts are calling for improved detection of opioid use disorders (OUDs) and treatment with buprenorphine or extended release (XR) injectable naltrexone, which can be prescribed in general medical settings. To better understand the magnitude of opportunities for treatment among primary care (PC) patients, we estimated the prevalence of documented OUD and medication treatment of OUD among PC patients.

METHODS

This cross-sectional study included patients with ≥2 visits to PC clinics across 6 healthcare delivery systems who were ≥16 years of age during the study period (fiscal years 2014-2016). Diagnoses, prescriptions, and healthcare utilization were ascertained from electronic health records and insurance claims (5 systems that also offer health insurance). Documented OUDs were defined as ≥1 International Classification of Diseases code for OUDs (active or remission), and OUD treatment was defined as ≥1 prescription(s) for buprenorphine formulations indicated for OUD or naltrexone XR, during the 3-year study period. The prevalence of documented OUD and treatment (95% confidence intervals) across health systems were estimated, and characteristics of patients by treatment status were compared. Prevalence of OUD and OUD treatment were adjusted for age, gender, and race/ethnicity. Combined results were also adjusted for site.

RESULT

Among 1,403,327 eligible PC patients, 54-62% were female and mean age ranged from 46 to 51 years across health systems. The 3-year prevalence of documented OUD ranged from 0.7-1.4% across the health systems. Among patients with documented OUD, the prevalence of medication treatment (primarily buprenorphine) varied across health systems: 3%, 12%, 16%, 20%, 22%, and 36%.

CONCLUSION

The prevalence of documented OUD and OUD treatment among PC patients varied widely across health systems. The majority of PC patients with OUD did not have evidence of treatment with buprenorphine or naltrexone XR, highlighting opportunities for improved identification and treatment in medical settings. These results can inform initiatives aimed at improving treatment of OUD in PC. Future research should focus on why there is such variation and how much of the variation can be addressed by improving access to medication treatment.

National outpatient medication utilization for opioid and alcohol use disorders from 2014 to 2016

BACKGROUND AND AIMS

Research has recommended a combination of pharmacotherapy and behavioral therapy to treat opioid use disorder (OUD) or alcohol use disorder (AUD). The objective of this study was to estimate the prevalence of U.S. outpatient visits in which patients had a documented OUD or AUD and in what proportion of these visits the patient was receiving medication for OUD (MOUD) or AUD (MAUD), alone or in combination with behavioral therapy.

DESIGN

Cross-sectional analysis of the National Ambulatory Medical Care Survey (NAMCS) from 2014 to 2016.

SETTING

NAMCS provides national estimates based on the latest census data, for all U.S. outpatient medical visits.

PARTICIPANTS/CASES

All visits involving patients aged ≥18 years with an OUD or AUD diagnosis.

MEASUREMENT

Medications for OUD included buprenorphine, buprenorphine/naloxone, or naltrexone; medications for AUD included acamprosate, disulfiram, or naltrexone. We defined behavioral therapy as provision of psychosocial therapy, mental health counseling, or stress management. We also compared annualized data between 2014 and 2016 using the Chi-square test.

FINDINGS

From 2014 to 2016, NAMCS recorded nearly 2.3 billion adult outpatient visits, including 17.1 million and 21.7 million visits involving patients with an OUD or AUD diagnosis, respectively. From 2014 to 2016, a decreased prevalence of annual visits involved AUD (11.7 vs. 9.9/1000, P < 0.0001), while those for OUD increased (9.3 vs. 13.3/1000, P < 0.0001). Among office visits with an OUD diagnosis, a MOUD was documented in 14.2 million (83.1%) visits and behavioral therapy was provided in 4.4 million (25.6%). Among office visits with an AUD diagnosis, an MAUD was documented in approximately 800,000 (3.6%) and behavioral therapy in 5.4 million (24.8%).

CONCLUSION

These data highlight an opportunity to increase the use of MAUD and offer behavioral therapy to those with OUD and/or AUD.

Medication Utilization for Alcohol Use Disorder in a Commercially Insured Population

OBJECTIVE

Examine patterns of alcohol use disorder (AUD) medication use and identify factors associated with prescription fill among commercially insured individuals with an index AUD visit.

DESIGN

Using 2008-2018 claims data from a large national insurer, estimate days to first AUD medication using cause-specific hazards approach to account for competing risk of benefits loss.

PARTICIPANTS

Aged 17-64 with ≥ 1 AUD visit.

MAIN MEASURE

Days to AUD medication fill.

KEY RESULTS

A total of 13.3% of the 151,128 with an index visit filled an AUD prescription after that visit, while 69.8% lost benefits before filling and 17.0% remained enrolled but did not fill (median days observed = 305). Almost half (46.3%) of those who filled a prescription received substance use disorder (SUD) inpatient care within 7 days before the fill, and 63.4% received SUD outpatient care. Likelihood of medication use was higher for those aged 26-35, 36-45, and 46-55 years relative to 56-64 years (e.g., 26-35: hazard ratio = 1.29 [95% confidence interval 1.23-1.36]); those diagnosed with moderate/severe AUD (2.05 [1.98-2.12]), co-occurring opioid use disorder (OUD) (1.33 [1.26-1.39]), or severe mental illness (1.31 [1.27-1.35]); those with a chronic alcohol-related diagnosis (1.08 [1.04-1.12]); and those whose index visit was in an inpatient/emergency department (1.27 [1.23-1.31]) or intermediate care setting (1.13 [1.07-1.20]) relative to outpatient. Likelihood of use was higher in later years relative to 2008 (e.g., 2018:2.02 [1.89-2.15]) and higher for those who received the majority of AUD care in a practice with a psychiatrist/addiction medicine specialist (1.13 [1.10-1.16]). Likelihood of use was lower for those diagnosed with a SUD other than AUD or OUD (0.88 [0.85-0.92]), those with an acute alcohol-related condition (0.79 [0.75-0.84]), and males (0.71 [0.69-0.73]).

CONCLUSIONS

While AUD medication use increased and was more common among individuals with greater severity, few patients who could benefit from medications are using them. More efforts are needed to identify and treat individuals in non-acute care settings earlier in their course of AUD.

Rates of prescription orders for United States active duty service members diagnosed with alcohol use disorder

BACKGROUND

Alcohol-use disorders (AUD) pose a significant challenge for the United States (US) military. The US Department of Defense has strongly recommended several medications for use in the treatment of patients with diagnosed AUD. This study assessed the prescription of medications for active duty service members (ADSMs) diagnosed with AUD in the US Military Health System (MHS). Methods: Rates of prescription orders were retrospectively examined from 2010 to 2017 among ADSMs with an incident diagnosis of moderate-to-severe AUD. The rate of prescription orders was defined as the proportion of ADSMs with an ICD-9 or ICD-10 diagnosis code of alcohol dependence who received an order for acamprosate, disulfiram, naltrexone, and/or topiramate at a military treatment facility in the year following their incident diagnosis. Results: ADSMs receiving an order for at least one medication in the year following their incident AUD diagnosis increased from 8.8% in 2010 to 16.2% in 2017 (RR = 1.84, 95% CI, 1.76, 1.93). Oral naltrexone was ordered most frequently among this patient population, while injectable naltrexone, a medication option meant to ease and improve adherence, was ordered for a smaller proportion of patients. Conclusions: Most ADSMs who might benefit from prescriptions for AUD are not receiving them as part of their treatment despite strong clinical evidence and Department of Defense policy support for their use among this cohort.

Overcoming Barriers to Adopting and Implementing Pharmacotherapy: the Medication Research Partnership

Pharmacotherapy includes a growing number of clinically effective medications for substance use disorder, yet there are significant barriers to its adoption and implementation in routine clinical practice. The Medication Research Partnership (MRP) was a successful effort to promote adoption of pharmacotherapy for opioid and alcohol use disorders in nine substance abuse treatment centers and a commercial health plan. This qualitative analysis of interviews (n = 39) conducted with change leaders at baseline and at the end/beginning of 6-month change cycles explains how treatment centers overcame obstacles to the adoption, implementation, and sustainability of pharmacotherapy. Results show that barriers to adopting, implementing, and sustaining pharmacotherapy can be overcome through incremental testing of organizational change strategies, accompanied by expert coaching and a learning community of like-minded professionals. The greatest challenges lie in overcoming abstinence-only philosophies, establishing a business case for pharmacotherapy, and working with payers and pharmaceutical representatives.

Prevalence of documented alcohol and opioid use disorder diagnoses and treatments in a regional primary care practice-based research network

BACKGROUND

Most people with alcohol or opioid use disorders (AUD or OUD) are not diagnosed or treated for these conditions in primary care. This study takes a critical step toward quantifying service gaps and directing improvement efforts for AUD and OUD by using electronic health record (EHR) data from diverse primary care organizations to quantify the extent to which AUD and OUD are underdiagnosed and undertreated in primary care practices.

METHODS

We extracted and integrated diagnosis, medication, and behavioral health visit data from the EHRs of 21 primary care clinics within four independent healthcare organizations representing community health centers and rural hospital-associated clinics in the Pacific Northwest United States. Rates of documented AUD and OUD diagnoses, pharmacological treatments, and behavioral health visits were evaluated over a two-year period (2015-2016).

RESULTS

Out of 47,502 adult primary care patients, 1476 (3.1%) had documented AUD; of these, 115 (7.8%) had orders for AUD medications and 271 (18.4%) had at least one documented visit with a non-physician behavioral health specialist. Only 402 (0.8%) patients had documented OUD, and of these, 107 (26.6%) received OUD medications and 119 (29.6%) had at least one documented visit with a non-physician behavioral health specialist. Rates of AUD diagnosis and AUD and OUD medications were higher in clinics that had co-located non-physician behavioral health specialists.

CONCLUSIONS

AUD and OUD are underdiagnosed and undertreated within a sample of independent primary care organizations serving mostly rural patients. Primary care organizations likely need service models, technologies, and workforces, including non-physician behavioral health specialists, to improve capacities to diagnose and treat AUD and OUD.

Availability of Medications for the Treatment of Alcohol and Opioid Use Disorder in the USA

Despite high mortality rates due to opioid overdose and excessive alcohol consumption, medications for the treatment of alcohol and opioid use disorder have not been widely used in the USA. This paper provides an overview of the literature on the availability of alcohol and opioid used disorder medications in the specialty substance use disorder treatment system, other treatment settings and systems, and among providers with a federal waiver to prescribe buprenorphine. We also present the most current data on the availability of alcohol and opioid use disorder medications in the USA. These estimates show steady growth in availability of opioid use disorder medications over the past decade and a decline in availability of alcohol use disorder medications. However, overall use of medications in the USA remains low. In 2017, only 16.3% of specialty treatment programs offered any single medication for alcohol use disorder treatment and 35.5% offered any single medication for opioid use disorder treatment. Availability of buprenorphine-waivered providers has increased significantly since 2002. However, geographic disparities in access to buprenorphine remain. Some of the most promising strategies to increase availability of alcohol and opioid use disorder medications include the following: incorporating substance use disorder training in healthcare education programs, educating the substance use disorder workforce about the benefits of medication treatment, reducing stigma surrounding the use of medications, implementing medications in primary care settings, implementing integrated care models, revising regulations on methadone and buprenorphine, improving health insurance coverage of medications, and developing novel medications for the treatment of substance use disorder.

Evidence for Misspecification of a Nationally Used Quality Measure for Substance Use Treatment

OBJECTIVES

The National Committee for Quality Assurance's (NCQA) measure "Initiation and Engagement of Alcohol and Other Drug Dependence Treatment" captures the proportion of substance use patients with (1) treatment initiation within 14 days and (2) treatment engagement within 30 days thereafter. The definition of treatment considers only counseling but not medication-assisted treatment (MAT), although MAT is supported by current guidelines. Our research question is whether this omission results in meaningful measurement error.

STUDY DESIGN AND METHODS

We analyze claims data for members of commercial health plans to investigate whether including MAT would meaningfully change the measure rate and health plan rankings.

RESULTS

Including MAT increased both the initiation and engagement rates. The initiation and engagement rates increased 2.4% (38.9-39.8%) and 9.9% (12.9-14%), respectively. These differences imply that 19% of health plans would change their ranking by at least one quintile for the initiation measure and 27% for the engagement measure.

CONCLUSIONS

The current specifications result in erroneous conclusions about the quality of care provided by different health plans. Our results suggest that aligning the measure specifications with guideline recommendations, as recently proposed by NCQA, would result in more accurate information.

Predictors of Medication-Assisted Treatment Initiation for Opioid Use Disorder in an Interdisciplinary Primary Care Model

INTRODUCTION

Medication-assisted treatment (MAT) for opioid use disorder (OUD) is underused in primary care. Little is known about patient demographics associated with MAT initiation, particularly among models with an interdisciplinary approach, including behavioral health integration. We hypothesize few disparities in MAT initiation by patient characteristics after implementing this model for OUD.

METHODS

Electronic health record data were used to identify adults with ≥1 primary care visit in 1 of 2 study clinics in a Pacific Northwest academic health system between September 1, 2015 and August 31, 2017 (n = 23,372). Rates of documented OUD diagnosis were calculated. Multivariate logistic regression estimated odds ratios of MAT initiation, defined as ≥1 electronic health record order for buprenorphine or naltrexone, by patient covariates.

RESULTS

Seven percent of the study sample had an OUD diagnosis. Of those patients, 32% had ≥1 MAT order. Patients with documented psychiatric diagnoses or tobacco use had higher odds of initiating MAT (odds ratio [OR] = 1.62, P = .0003; OR = 2.46, P < .0001, respectively). Uninsured, Medicaid, and Medicare patients had lower odds than those commercially insured (OR = 0.53, 0.38, and 0.31, respectively; P < .0001). Patients who were older, of a race/ethnicity other than non-Hispanic white, had documented diabetes, and had documented asthma or chronic obstructive pulmonary disease showed lower odds of initiation.

DISCUSSION

MAT initiation varied by patient characteristics, including disparities by insurance coverage and race/ethnicity. The addition of behavioral health did not eliminate disparities in care, but higher odds of initiation among those with a documented psychiatric diagnosis may suggest this model reaches some vulnerable populations. Additional research is needed to further examine these findings.

Intent to Refer: Exploring Bias Toward Specific Medication-Assisted Treatments by Community Corrections Employees

BACKGROUND

As opioid use increases in the United States, especially in the correctional population, the most effective treatment approaches need to be utilized. Research has shown that medication-assisted treatment (MAT) provides better outcomes than traditional treatment approaches alone, but is underutilized among correctional-supervised populations.

OBJECTIVE

This article looks at how previously identified barriers to implementing MAT can create potential biases regarding the intent to refer individuals to either buprenorphine or methadone among treatment and correctional staff within community corrections. The varying advantages of each medication are discussed to highlight the importance of individualized treatment planning.

METHODS

Data were collected from 959 treatment specialists and community-corrections officers between 2010 and 2013. The participants were employed by one of 20 community corrections agencies that were selected and randomized within a cluster design. The data were part of a larger study that tested how the experimental condition of organizational linkages impacted the use of MAT in the criminal justice system. In order to analyze the data, multinomial logistic regression was used.

RESULTS

Results showed that some community corrections employees were likely to refer clients to use methadone, but not buprenorphine (or vice versa) which was influenced by work setting, level of education, training, and negative perceptions of MAT as a substitute addiction. However, these biases could be minimized by proper training.

CONCLUSION

These findings suggest that proper training should be mandatory for these employees and include information about various MATs while also addressing the negative perception that MAT is a substitute addiction.

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.

Personalized medicine and Hispanic health: improving health outcomes and reducing health disparities - a National Heart, Lung, and Blood Institute workshop report

Persons of Hispanic/Latino descent may represent different ancestries, ethnic and cultural groups and countries of birth. In the U.S., the Hispanic/Latino population is projected to constitute 29% of the population by 2060. A personalized approach focusing on individual variability in genetics, environment, lifestyle and socioeconomic determinants of health may advance the understanding of some of the major factors contributing to the health disparities experienced by Hispanics/Latinos and other groups in the U.S., thus leading to new strategies that improve health care outcomes. However, there are major gaps in our current knowledge about how personalized medicine can shape health outcomes among Hispanics/Latinos and address the potential factors that may explain the observed differences within this heterogeneous group, and between this group and other U.S. demographic groups. For that purpose, the National Heart, Lung, and Blood Institute (NHLBI), in collaboration with the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), and the Food and Drug Administration (FDA), held a workshop in which experts discussed (1) potential approaches to study medical treatments and health outcomes among Hispanics/Latinos and garner the necessary evidence to fill gaps of efficacy, effectiveness and safety of therapies for heart, lung, blood and sleep (HLBS) disorders and conditions--and their risk factors; (2) research opportunities related to personalized medicine to improve knowledge and develop effective interventions to reduce health disparities among Hispanics/Latinos in the U.S.; and (3) the incorporation of expanded sociocultural and socioeconomic data collection and genetic/genomic/epigenetic information of Hispanic/Latino patients into their clinical assessments, to account for individual variability in ancestry; physiology or disease risk; culture; environment; lifestyle; and socioeconomic determinants of health. The experts also provided recommendations on: sources of Hispanic/Latino health data and strategies to enhance its collection; policy; genetics, genomics and epigenetics research; and integrating Hispanic/Latino health research within clinical settings.

Stressful Events and Other Predictors of Remission from Drug Dependence in the United States: Longitudinal Results from a National Survey

This study examined stressful life events and other predictors associated with remission from DSM-IV drug dependence involving cannabis, cocaine, hallucinogens, heroin, inhalants, non-heroin opioids, sedatives, stimulants, tranquilizers, or other drugs. Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions were used to examine the prevalence and predictors of past-year remission status. Among U.S. adults with previous (i.e., prior-to-past-year) drug dependence (n=921) at baseline (wave 1), the prevalence of past-year remission status at wave 1 was: abstinence (60.5%), asymptomatic drug use (18.8%), partial remission (7.1%), and still drug dependent (13.5%). Similarly, the prevalence of past-year remission status three years after baseline at wave 2 was: abstinence (69.1%), asymptomatic drug use (15.5%), partial remission (8.4%), and still drug dependent (7.0%). Remission three years after baseline at wave 2 was much more likely among formerly drug dependent U.S. adults who abstained from drug use at baseline (wave 1) relative to those who reported asymptomatic drug use, partial remission, or remained drug dependent. Design-based weighted multinomial logistic regression analysis showed that relative to abstinence, past-year stressful events at baseline (wave 1) predicted higher odds of partial remission and drug dependence at both waves 1 and 2. This is the first national study to examine the potential role of stressful life events associated with remission from drug dependence. Although the majority of those who reported previous drug dependence transitioned to full remission, a sizeable percentage were either still drug dependent or in partial remission. Higher levels of stressful life events appear to create barriers to remission and should remain a focus for relapse prevention programs.
