Substance Use Disorders in the Geriatric Population: a Review and Synthesis of the Literature of a Growing Problem in a Growing Population

Substance use problems and disorders among adults 50 years and older receiving mental health treatment for a primary neurocognitive disorder

OBJECTIVES

This study sought to (1) identify the percentage of high-risk substance use or substance use disorder (SUD) and (2) examine the factors associated with high-risk substance use or SUD in adults aged 50 years and older receiving mental health treatment with a primary delirium or dementia diagnosis.

METHOD

This study used 7 years (2013-2019) of national administrative data on community mental health center patients aged 50 years and older with a primary delirium or dementia diagnosis receiving treatment in the United States (U.S.). To examine factors associated with the dependent variable (high-risk substance use or SUD), a multivariable binary logistic regression model was utilized.

RESULTS

The sample included 77,509 individuals who were mostly aged 65 years and older (69.7%), and did not have co-occurring high-risk substance use or SUD (90.1%). Receiving treatment in a U.S. region other than the Northeast, being younger, male, not non-Hispanic White, and having multiple mental health diagnoses had greater odds of co-occurring high-risk substance use or SUD.

CONCLUSION

One in ten persons in this sample having high-risk substance use or SUD highlights the clinical necessity for screening and subsequent treatment for co-occurring high-risk substance use among persons receiving treatment for a neurocognitive disorder.

The Nexus of Aging and Substance Use: A Scoping Review of Therapeutic Modalities for Geriatric Substance Use Disorders

The insidious grip of substance use disorders (SUDs) manifests as a ubiquitous public health crisis, indiscriminately affecting individuals across the spectrum of age, gender, and socioeconomic status. While advancements in treatment offer a glimmer of hope, millions continue to grapple with the debilitating physical, psychological, and social consequences of addiction, particularly those involving alcohol and opioids. This crisis is further exacerbated by the alarming rise of SUDs among older adults. As the global population undergoes a process of demographic senescence, the escalating prevalence of SUDs in this demographic underscores the urgent need for nuanced interventions. This review explores the therapeutic landscape for managing SUDs in older adults, evaluating pharmacological and non-pharmacological treatment modalities. A detailed literature search was conducted using databases like PubMed, Google Scholar, and Scopus, and studies were selected based on their relevance to therapeutic interventions for older adults with SUDs, encompassing pharmacological and non-pharmacological modalities. The synthesized results provide an extensive overview of contemporary therapeutic approaches. The findings indicate that pharmacological interventions demonstrate varied effectiveness in managing opioid and alcohol use disorders, with each drug offering distinct benefits and limitations regarding safety, tolerability, and patient adherence. Non-pharmacological interventions provide critical psychological and social support, often requiring adaptations to meet elderly patients' needs effectively. Integrated care models, which combine pharmacological and non-pharmacological treatments, emerge as the most effective approach, addressing the comprehensive needs of elderly patients by leveraging multidisciplinary teams, centralized service access, and coordinated, patient-centered care. Implementing these models, however, requires overcoming significant resource and coordination challenges. Indeed, the confluence of a burgeoning geriatric population and escalating rates of SUDs necessitates the development and implementation of granular and integrated care protocols specifically designed for older adults. By employing such a targeted approach, optimism can be cultivated and the quality of life enhanced for this vulnerable and often overlooked segment of society. This ensures the fight against addiction extends its reach, leaving no one behind.

Gaining Recovery in Addiction for Community Elders (GRACE) Project: The Impact of Age-Specific Care on Clinical Outcomes and Health Care Resource Utilization in Older Adults With Substance Use Disorder in an Interprofessional Addiction Clinic

BACKGROUND

The prevalence of substance use disorders (SUDs) in older adults has been increasing, necessitating tailored and effective addiction care for this aging demographic.

AIMS

The purpose of this study was to assess the impact of age-specific, interprofessional addiction care on clinical outcomes and health care resource utilization in older adults with SUD.

METHODS

This quasi-experimental study directly compares patients enrolled in the Gaining Recovery in Addiction for Community Elders (GRACE) Project, an interprofessional age-specific addictions treatment program, with age-matched older adults who received conventional "treatment as usual" (TAU). Through retrospective comparative analysis, substance use outcomes, mental and physical health improvements, and inappropriate use of emergency services were examined among 78 older adults with SUD.

RESULTS

Clinical outcomes and health care resource utilization were superior for older adults who received age-specific addictions care through the GRACE Project, as compared to mixed-age conventional "TAU." GRACE patients had improved treatment adherence, fewer relapses, and longer treatment engagement. While both groups exhibited significant reductions in depression and anxiety scores, GRACE patients showed greater improvements. This group demonstrated superior control of both hypertension and diabetes. Importantly, they had fewer inappropriate emergency department visits and avoidable hospitalizations than conventional "TAU."

CONCLUSIONS

Addiction treatment delivered by an interprofessional team to meet the unique strengths and needs of older adults has the potential to improve treatment adherence and more favorable long-term outcomes in substance use, mental health, and chronic medical conditions. Nurses are poised to lead interprofessional teams to meet the growing demand for specialized addiction treatment and integrated care for older adults.

Drug safety in older patients with alcohol use disorder: a retrospective cohort study

Background

Older patients with alcohol use disorder are at particular risk of developing adverse drug reactions due to multimorbidity, polypharmacy, and altered organ function.

Objectives

In this study, we investigated the frequency and characteristics of potentially serious alcohol-medication interactions, potentially inappropriate medications (PIMs) for older adults, and potential drug-drug interactions (pDDIs) in a population of older patients with alcohol use disorder over a 10-year period.

Design

Retrospective monocentric cohort study.

Methods

Prescribed medications were screened for potentially serious alcohol-medication interactions, PIMs, and pDDIs using the POSAMINO (POtentially Serious Alcohol-Medication INteractions in Older adults) criteria, the PRISCUS 2.0 list, the FORTA (Fit fOR The Aged) classification, and the drug interaction program AiDKlinik®.

Results

We enrolled 114 patients aged ⩾65 years with alcohol use disorder, who were treated in an addiction unit of a university hospital in Germany. About 80.7% of the study population had at least one potentially serious alcohol-medication interaction. Potentially serious alcohol-medication interactions most commonly affected the cardiovascular (57.7%) and the central nervous system (32.3%). A total of 71.1% of the study population received at least one prescription of a FORTA C or D drug, compared with 42.1% who received at least one PIM prescription according to the PRISCUS 2.0 list. A total of 113 moderate and 72 severe pDDIs were identified in the study population.

Conclusion

Older patients with alcohol use disorders are frequently exposed to potentially serious alcohol-medication interactions, PIMs, and pDDIs. Improvements in the quality of prescribing should primarily target the use of cardiovascular and psychotropic drugs.
