Substance Use Disorders Among Medicare Beneficiaries: Prevalence, Mental and Physical Comorbidities, and Treatment Barriers

INTRODUCTION

This study aimed to determine the prevalence of treated and untreated substance use disorders among Medicare beneficiaries, the characteristics of Medicare beneficiaries with substance use disorders, and reasons for their unmet needs.

METHODS

This study used data from the National Survey of Drug Use and Health, 2015-2019. Substance use disorder was defined based on DSM-IV dependence or abuse criteria. Descriptive analyses were conducted in 2021, including testing for differences in unadjusted means.

RESULTS

Approximately 1.7 million Medicare beneficiaries were estimated to have past-year substance use disorder (8% of Medicare beneficiaries aged <65 years and 2% aged ≥65 years). Overall, 77% had an alcohol use condition, 16% had a prescription drug use condition, and 10% had a marijuana use condition. Of those who had past-year substance use disorder, 11% received treatment for their condition. Common reasons for not receiving treatment were lack of motivation (41%), financial barriers (33%), concern about what others might think (24%), logistical barriers such as lack of transportation (21%), and uncertainty about treatment efficacy (13%). Medicare beneficiaries with substance use disorders were more than twice as likely to have past-year serious psychological distress as those without substance use disorders (44% vs 21%, p<0.001 for those aged <65 years; 14% vs 4%, p<0.001 for those aged ≥65 years). Percentages of past-year suicidal ideation were also much higher among Medicare beneficiaries with substance use disorders than without (24% vs 6%, p<0.001 for those aged <65 years; 7% vs 2%, p=0.006 for those aged ≥65 years).

CONCLUSIONS

Few Medicare beneficiaries who need substance use disorder treatment receive it. Reducing Medicare coverage gaps and stigma may help meet this need.

A scoping review exploring the ‘grey area’ of suicide-related expression in later life: Developing a conceptual framework for professional engagement

As the body of research on suicide in later life has developed, so has its vocabulary. This has generated a high level of overlap in concepts and terminology used to articulate suicide and how it might present, as well as ‘grey area’ behavioural terms that are both specific to older adults and less well-defined (e.g. ‘hastening of death’ or ‘completed life’). A better understanding of individual experiences and pathways to suicide can help to inform assessment and interventions, and increase the potential to relate any theoretical concepts to the implementation of such. Here, we adopted a scoping review to search systematically literature on specific presentation, features, circumstances and outcomes of these grey areas of suicide in later life. Fifty-three articles (quantitative, qualitative and theoretical) were reviewed. A narrative approach was used to merge and translate this body of knowledge into a new conceptual framework based on four key themes: (a) a sense of completed life or existential loneliness; (b) death thoughts, wishes and ideation; (c) death-hastening behaviour and advanced directives; and (d) self-destructive or self-injurious behaviour. We discuss the importance of integrating this understanding into current knowledge and suicide prevention strategies for older adults. Recommendations are made for unifying research with policy themes on healthy ageing, person-centredness within service provision and citizen participation.

Alcohol Use Disorder in Older Adults

As the number of older adults worldwide continues to grow, we observe a proportional growth of substance use. Despite the myriad of complications alcohol use disorder (AUD) has on the body with regards to organ systems and mental health, the topic has been underresearched in the older adult population. Thus, it is important to create awareness about the growing problem of AUD among older adults. In this way, we can mitigate the long-term complications and side effects observed with alcohol abuse in this vulnerable population.
