Expanding access to medication treatment for opioid use disorders: Findings from the Washington State hub and spoke effort.

BACKGROUND: Opioid use disorder (OUD) is a leading cause of preventable death and injury nationwide. Efforts to increase the use of medication for opioid use disorder (MOUD) are needed. In 2017, Washington State implemented a Hub and Spoke (HS) model of care with the primary goal of expanding access to MOUD. We examined changes in MOUD utilization among Washington State Medicaid beneficiaries before and after HS implementation. METHODS: We used Medicaid claims data to examine longitudinal changes in MOUD use for beneficiaries with OUD. We conducted a comparative interrupted time series analysis to examine the association between HS policy implementation and rates of MOUD utilization, overall and by type of medication. RESULTS: Between 2016 and 2019, a period of increasing OUD prevalence, rates of MOUD utilization among Washington Medicaid beneficiaries increased overall from 39.7 to 50.5. Following HS implementation, rates of MOUD use grew at a significantly greater rate in the HS cohort than in the non-HS cohort (ß=0.54, SE=0.02, p< 0.0001, 95% CI 0.49, 0.59). Analyses by medication type show that this rate increase was primarily due to buprenorphine use (ß= 0.61, SE= 0.02, p< 0.0001, 95% CI 0.57, 0.65). CONCLUSION: Improved systems of care are needed to make MOUD accessible to all patients in need. The Washington HS model is one strategy that may facilitate and expand MOUD use, particularly buprenorphine. Over the study period, Washington State saw increased use of buprenorphine, which was an emphasis of their HS model.

Quality of Opioid Use Disorder Treatment for Persons With and Without Disabling Conditions.

Importance: Adverse outcomes associated with opioid use disorder (OUD) are disproportionately high among people with disabilities (PWD) compared with those without disability. A gap remains in understanding the quality of OUD treatment for people with physical, sensory, cognitive, and developmental disabilities, specifically regarding medications for OUD (MOUD), a foundation of treatment. Objective: To examine the use and quality of OUD treatment in adults with diagnosed disabling conditions, compared with adults without these diagnoses. Design, Setting, and Participants: This case-control study used Washington State Medicaid data from 2016 to 2019 (for use) and 2017 to 2018 (for continuity). Data were obtained for outpatient, residential, and inpatient settings with Medicaid claims. Participants included Washington State full-benefit Medicaid enrollees aged 18 to 64 years, continuously eligible for 12 months, with OUD during the study years and not enrolled in Medicare. Data analysis was performed from January to September 2022. Exposures: Disability status, including physical (spinal cord injury or mobility impairment), sensory (visual or hearing impairments), developmental (intellectual or developmental disability or autism), and cognitive (traumatic brain injury) disabilities. Main Outcomes and Measures: The main outcomes were National Quality Forum-endorsed quality measures: (1) use of MOUD (buprenorphine, methadone, or naltrexone) during each study year and (2) 6-month continuity of treatment (for those taking MOUD). Results: A total of 84 728 Washington Medicaid enrollees had claims evidence of OUD, representing 159 591 person-years (84 762 person-years [53.1%] for female participants, 116 145 person-years [72.8%] for non-Hispanic White participants, and 100 970 person-years [63.3%] for participants aged 18-39 years); 15.5% of the population (24 743 person-years) had evidence of a physical, sensory, developmental, or cognitive disability. PWD were 40% less likely than those without a disability to receive any MOUD (adjusted odds ratio [AOR], 0.60; 95% CI, 0.58-0.61; P < .001). This was true for each disability type, with variations. Individuals with a developmental disability were least likely to use MOUD (AOR, 0.50; 95% CI, 0.46-0.55; P < .001). Of those using MOUD, PWD were 13% less likely than people without disability to continue MOUD for 6 months (adjusted OR, 0.87; 95% CI, 0.82-0.93; P < .001). Conclusions and Relevance: In this case-control study of a Medicaid population, treatment differences were found between PWD and people without these disabilities; these differences cannot be explained clinically and highlight inequities in treatment. Policies and interventions to increase MOUD access are critical to reducing morbidity and mortality among PWD. Potential solutions include improved enforcement of the Americans with Disabilities Act, workforce best practice training, and addressing stigma, accessibility, and the need for accommodations to improve OUD treatment for PWD.

Evaluating the feasibility and impact of case rate payment for recovery support navigator services: a mixed methods study.

BACKGROUND: Acute 24-h detoxification services (detox) are necessary but insufficient for many individuals working towards long-term recovery from opiate, alcohol or other drug addiction. Longer engagement in substance use disorder (SUD) treatment can lead to better health outcomes and reductions in overall healthcare costs. Connecting individuals with post-detox SUD treatment and supportive services is a vital next step. Toward this end, the Massachusetts Medicaid program reimburses Community Support Program staff (CSPs) to facilitate these connections. CSP support services are typically paid on a units-of-service basis. As part of a larger study testing health care innovations, one large Medicaid insurer developed a new cadre of workers, called Recovery Support Navigators (RSNs). RSNs performed similar tasks to CSPs but received more extensive training and coaching and were paid an experimental case rate (a flat negotiated reimbursement). This sub-study evaluates the feasibility and impact of case rate payments for RSN services as compared to CSP services paid fee-for-service. METHODS: We analyzed claims data and RSN service data for a segment of the Massachusetts Medicaid population who had more than one detox admission in the last year and also engaged in post-discharge CSP or RSN services. Qualitative data from key informant interviews and Learning Collaboratives with CSPs and RSNs supplemented the findings. RESULTS: Clients receiving RSN services under the case rate utilized the service significantly longer than clients receiving CSP services under unit-based billing. This resulted in a lower average cost per member per month for RSN clients. However, when calculating total SUD treatment costs per member, RSN client costs were 50% higher than CSP client costs. Provider organizations employing RSNs successfully implemented case rate billing. Benefits included allowing time for outreach efforts and training and coaching, activities not paid under the unit-based system. Yet, RSNs identified staffing and larger systems level challenges to consider when using a case rate payment model. CONCLUSIONS: Addiction is a chronic disease that requires long-term investments. Case rate billing offers a promising option for payers and providers as it promotes continued engagement with service providers. To fully realize the benefits of case rate billing, however, larger systems level changes are needed.

Impact of recovery support navigators on continuity of care after detoxification.

Although evidence points to the benefits of continuity of care after detoxification (detox), especially when continuity of care occurs within a short time after discharge from a detox episode, the rate at which clients engage in continued treatment after detox remains low. The goal of the study was to develop and deploy a specially trained workforce, called recovery support navigators (RSNs), to increase the likelihood of clients continuing onto treatment after detox. Continuity of care is defined as receiving any substance use disorder (SUD) treatment service within 14 days of discharge from the index detox. We examined whether clients in the RSN Intervention group were more likely to meet the continuity of care after detox criteria than clients in the treatment-as-usual (TAU) group. A quasi-experimental intervention versus comparison group study was conducted. Data were from the Massachusetts Behavioral Health Partnership (MBHP), a Beacon Health Options company that manages behavioral health benefits for a subset of Medicaid beneficiaries in the state. Inclusion in the analytic sample (N = 4,236) required that the client's index admission to detox was between 3/29/13 and 3/31/15. RSN Intervention versus TAU status was assigned based on provider organization where the index detox occurred. Analyses were conducted on an intent-to-treat basis. Overall, the continuity of care rate across all study groups was 42%. The rate by study group was 38% for the TAU and 45% for the RSN group. Clients who were in the RSN group were significantly more likely to have continuity of care after discharge from detox than those in the TAU (OR = 1.233, p < .05, 95% CI = 1.044, 1.455). Clients who entered detox at a site that provided specialized training to RSN, which included motivational interviewing and educational sessions related to treatment issues, and allowing them to bill with a flexible daily case rate instead of the usual fee-for-service billing, were more likely to have continuity of care after discharge from detox compared to clients in the TAU group.

Impact of Agency Receipt of Incentives and Reminders on Engagement and Continuity of Care for Clients With Co-Occurring Disorders.

OBJECTIVE: This study examined whether having co-occurring substance use and mental disorders influenced treatment engagement or continuity of care and whether offering financial incentives, client-specific electronic reminders, or a combination to treatment agencies improved treatment engagement and continuity of care among clients with co-occurring disorders. METHODS: The study used a randomized cluster design to assign agencies (N=196) providing publicly funded substance use disorder treatment in Washington State to a research arm: incentives only, reminders only, incentives and reminders, and a control condition. Data were analyzed for 76,044 outpatient, 32,797 residential, and 39,006 detoxification admissions from Washington's treatment data system. Multilevel logistic regressions were conducted, with clients nested within agencies, to examine the effect of the interventions on treatment engagement and continuity of care. RESULTS: Compared with clients with a substance use disorder only, clients with co-occurring disorders were less likely to engage in outpatient treatment or have continuity of care after discharge from residential treatment, but they were more likely to have continuity of care after discharge from detoxification. The interventions did not influence treatment engagement or continuity of care, except the reminders had a positive impact on continuity of care after residential treatment among clients with co-occurring disorders. CONCLUSIONS: In general, the interventions did not result in improved treatment engagement or continuity of care. The limited number of significant results supporting the influence of incentives and alerts on treatment engagement and continuity of care add to the mixed findings reported by previous research. Multiple interventions may be needed for performance improvement.

Agency-level financial incentives and electronic reminders to improve continuity of care after discharge from residential treatment and detoxification.

BACKGROUND: Despite the importance of continuity of care after detoxification and residential treatment, many clients do not receive further treatment services after discharged. This study examined whether offering financial incentives and providing client-specific electronic reminders to treatment agencies lead to improved continuity of care after detoxification or residential treatment. METHODS: Residential (N = 33) and detoxification agencies (N = 12) receiving public funding in Washington State were randomized into receiving one, both, or none (control group) of the interventions. Agencies assigned to incentives arms could earn financial rewards based on their continuity of care rates relative to a benchmark or based on improvement. Agencies assigned to electronic reminders arms received weekly information on recently discharged clients who had not yet received follow-up treatment. Difference-in-difference regressions controlling for client and agency characteristics tested the effectiveness of these interventions on continuity of care. RESULTS: During the intervention period, 24,347 clients received detoxification services and 20,685 received residential treatment. Overall, neither financial incentives nor electronic reminders had an effect on the likelihood of continuity of care. The interventions did have an effect among residential treatment agencies which had higher continuity of care rates at baseline. CONCLUSIONS: Implementation of agency-level financial incentives and electronic reminders did not result in improvements in continuity of care, except among higher performing agencies. Alternative strategies at the facility and systems levels should be explored to identify ways to increase continuity of care rates in specialty settings, especially for low performing agencies.

Implementation of Client Incentives within a Recovery Navigation Program.

OBJECTIVE: Multiple detoxification admissions among clients with substance use disorders (SUD) are costly to the health care system. This study explored the impact on behavior and cost outcomes of recovery support navigator (RSN) services delivered with and without a contingent incentive intervention. METHODS: New intakes at four detoxification programs were offered RSN-only (N=1116) or RSN plus incentive (RSN+I; N=1551) services. The study used a group-level cross-over design with the intervention in place at each clinic reversed halfway through the enrollment period. RSN+I clients could earn up to $240 in gift cards for accomplishing 12 different recovery-oriented target behaviors. All eligible clients entering the detoxification programs were included in the analyses, regardless of actual service use. RESULTS: Among RSN+I clients, 35.5% accessed any RSN services compared to 22.3% in the RSN-only group (p<.01). Of RSN+I clients, 19% earned one, 12% earned two and 18% earned three or more incentives; 51% did not earn any incentives. The majority of incentives earned were for meeting with the RSN either during or after detoxification. Adjusted average monthly health care costs among clients in the RSN-only and RSN+I groups increased at a similar rate over 12 months post-detoxification. DISCUSSION: Possible explanations for limited uptake of the incentive program discussed include features of the incentive program itself, navigator-client communication, organizational barriers and navigator bias. The findings provide lessons to consider for future design and implementation of multi-target contingency management interventions in real-world settings.

Testing novel patient financial incentives to increase breast cancer screening.

OBJECTIVES: To examine the effects of 3 types of low-cost financial incentives for patients, including a novel "person-centered" approach on breast cancer screening (mammogram) rates. STUDY DESIGN: Randomized controlled trial with 4 arms: 3 types of financial incentives ($15 gift card, entry into lottery for $250 gift card, and a person-centered incentive with choice of $15 gift card or lottery) and a control group. Sample included privately insured Tufts Health Plan members in Massachusetts who were women aged 42 to 69 years with no mammogram claim in ≥ 2.6 years. METHODS: A sample of 4700 eligible members were randomized to 4 study arms. The control group received a standard reminder letter and the incentive groups received a reminder letter plus an incentive offer for obtaining a mammogram within the next 4 months. Bivariate tests and multivariate logistic regression were used to assess the incentives' impact on mammogram receipt. Data were analyzed for 4427 members (after exclusions such as undeliverable mail). RESULTS: The percent of members receiving a mammogram during the study was 11.7% (gift card), 12.1% (lottery), 13.4% (person-centered/choice), and 11.9% (controls). Differences were not statistically significant in bivariate or multivariate full-sample analyses. In exploratory subgroup analyses of members with a mammogram during the most recent year prior to the study-defined gap, person-centered incentives were associated with a higher likelihood of mammogram receipt. CONCLUSIONS: None of the low-cost incentives tested had a statistically significant effect on mammogram rates in the full sample. Exploratory findings for members who were more recently screened suggest that they may be more responsive to person-centered incentives.

A performance measure for continuity of care after detoxification: relationship with outcomes.

Administrative data from five states were used to examine whether continuity of specialty substance abuse treatment after detoxification predicts outcomes. We examined the influence of a 14-day continuity of care process measure on readmissions. Across multiple states, there was support that clients who received treatment for substance use disorders within 14-days after discharge from detoxification were less likely to be readmitted to detoxification. This was particularly true for reducing readmissions to another detoxification that was not followed with treatment and when continuity of care was in residential treatment. Continuity of care in outpatient treatment was related to a reduction in readmissions in some states, but not as often as when continuity of care occurred in residential treatment. A performance measure for continuity of care after detoxification is a useful tool to help providers monitor quality of care delivered and to alert them when improvement is needed.

Drinking patterns of older adults with chronic medical conditions.

BACKGROUND: Understanding alcohol consumption patterns of older adults with chronic illness is important given the aging baby boomer generation, the increase in prevalence of chronic conditions and associated medication use, and the potential consequences of excessive drinking in this population. OBJECTIVES: To estimate the prevalence of alcohol consumption patterns, including at-risk drinking, in older adults with at least one of seven common chronic conditions. DESIGN/METHODS: This descriptive study used the nationally representative 2005 Medicare Current Beneficiary Survey linked with Medicare claims. The sample included community-dwelling, fee-for-service beneficiaries 65 years and older with one or more of seven chronic conditions (Alzheimer's disease and other senile dementia, chronic obstructive pulmonary disease, depression, diabetes, heart failure, hypertension, and stroke; n = 7,422). Based on self-reported alcohol consumption, individuals were categorized as nondrinkers, within-guidelines drinkers, or at-risk drinkers (exceeds guidelines). RESULTS: Overall, 30.9 % (CI 28.0-34.1 %) of older adults with at least one of seven chronic conditions reported alcohol consumption in a typical month in the past year, and 6.9 % (CI 6.0-7.8 %) reported at-risk drinking. Older adults with higher chronic disease burdens were less likely to report alcohol consumption and at-risk drinking. CONCLUSIONS: Nearly one-third of older adults with selected chronic illnesses report drinking alcohol and almost 7 % drink in excess of National Institute on Alcohol Abuse and Alcoholism (NIAAA) guidelines. It is important for physicians and patients to discuss alcohol consumption as a component of chronic illness management. In cases of at-risk drinking, providers have an opportunity to provide brief intervention or to offer referrals if needed.

Older adults' inpatient and emergency department utilization for ambulatory-care-sensitive conditions: relationship with alcohol consumption.

OBJECTIVE: This study examined the relationship between drinking that exceeds guideline-recommended limits and acute-care utilization for ambulatory-care-sensitive conditions (ACSCs) by older Medicare beneficiaries. METHOD: This secondary data analysis used the 2001-2006 Medicare Current Beneficiary Survey (unweighted n = 5,570 community dwelling, past-year drinkers, 65 years and older). Self-reported alcohol consumption (categorized as within guidelines, exceeding monthly but not daily limits, or heavy episodic) and covariates were used to predict ACSC hospitalization, emergency department visit not resulting in admission, and emergency department visit that did result in admission. RESULTS: Heavy episodic drinking was significantly associated with higher likelihood of an ACSC emergency department visit not resulting in admission (adjusted odds ratio = 1.91, 95% CI: 1.11-3.30; p < .05). Drinking pattern was not significant for other ACSC measures. DISCUSSION: Results partially support the hypothesis that excessive drinking may be related to ACSC acute-care utilization among older adults, suggesting increased risk of lower quality outpatient care.

Unhealthy drinking patterns and receipt of preventive medical services by older adults.

BACKGROUND: Preventive service use among older adults is suboptimal. Unhealthy drinking may constitute a risk factor for failure to receive these services. OBJECTIVES: To determine the relationship between unhealthy drinking and receipt of recommended preventive services among elderly Medicare beneficiaries, applying the framework of current alcohol consumption guidelines. DESIGN/METHODS: The data source is the nationally representative 2003 Medicare Current Beneficiary Survey. The sample included community-dwelling, fee-for-service Medicare beneficiaries 65 years and older (N = 10,523). Based on self-reported drinking, respondents were categorized as nondrinkers, within-guidelines drinkers, exceeding monthly but not daily limits, or heavy episodic drinkers. Using survey and claims data, influenza vaccination, pneumonia vaccination, glaucoma screening, and mammogram receipt were determined. Bivariate and logistic regression analyses were conducted. RESULTS: Overall, 70.3% received flu vaccination and 49% received glaucoma screening during the year, 66.8% received pneumonia vaccination, and 56.2% of women received a mammogram over 2 years. In logistic regression, heavy episodic drinking was associated with lower likelihood of service receipt compared to drinking within guidelines: flu vaccination (OR 0.75, CI 0.59-0.96), glaucoma screening (OR 0.74, CI 0.58-0.95), and pneumonia vaccination (OR 0.75, CI 0.59-0.96). Nondrinkers when compared with those reporting drinking within guidelines were less likely to receive a mammogram (OR 0.83, CI 0.69-1.00). CONCLUSIONS: Heavy episodic drinking is associated with lower likelihood of receiving several preventive services. Practitioners should be encouraged to screen all elders regarding alcohol intake and in addition to appropriate intervention, consider elders reporting heavy episodic drinking at higher risk for non-receipt of preventive services.

Unhealthy drinking patterns in older adults: prevalence and associated characteristics.

OBJECTIVES: To examine the prevalence of unhealthy drinking patterns in community-dwelling older adults and its association with sociodemographic and health characteristics. DESIGN: Cross-sectional analysis of nationally representative survey data. SETTING: The data source was the 2003 Access to Care file of the Medicare Current Beneficiary Survey, which represents the continuously enrolled Medicare population. PARTICIPANTS: Community-dwelling Medicare beneficiaries aged 65 and older (N=12,413). MEASUREMENTS: The prevalence of unhealthy alcohol use by older adults defined in relation to two parameters of recommended limits: monthly use exceeding 30 drinks per typical month and "heavy episodic" drinking of four or more drinks in any single day during a typical month in the previous year. Sociodemographic and health status variables were also included. RESULTS: Nine percent of elderly Medicare beneficiaries reported unhealthy drinking, with higher prevalence in men (16%) than women (4%). In logistic regression analyses with the full sample, higher education and income; better health status; male sex; younger age; smoking; being white; and being divorced, separated, or single were associated with higher likelihood of unhealthy drinking. Among drinkers, in addition to sociodemographic variables, self-reported depressive symptoms were positively associated with unhealthy drinking. Among unhealthy drinkers, race and ethnicity variables were associated with likelihood of heavy episodic drinking. CONCLUSION: Almost one in 10 elderly Medicare beneficiaries report exceeding recommended drinking limits. Several distinct unhealthy drinking patterns were identified and associated with sociodemographic and health characteristics, suggesting the value of additional targeted approaches within the context of universal screening to reduce alcohol misuse by older adults.
