Substance Use Disorders in Later Life: A Review and Synthesis of the Literature of an Emerging Public Health Concern

Barriers to Healthcare and Social Service Utilization Among Rural Older Adults Who Use Drugs

The objective of this study was to understand barriers to healthcare and social service utilization among older adults residing in rural areas who use drugs. A cross-sectional survey of persons who use opioids or inject drugs in rural counties with high overdose rates across ten states was conducted. For this analysis, participants were restricted to only the 375 individuals aged 50 and older. They were asked about barriers to utilizing healthcare and social services. Multivariate analyses were conducted. The most common barriers were a lack of transportation and a fear of stigma. The average number of barriers was 2.53. Those who were either uninsured or homeless endorsed 37% more barriers. For every five-year increase in age, the number of barriers reduced by 15%. Efforts to reduce these barriers may include expanding eligibility for transportation and housing services and leveraging trusted community members to broker linkages to providers to overcome stigma.

Prevalence of alcohol use among U.S. older adults with pain: A scoping review

The majority of older adults in the United States (U.S.) have been bothered by pain in the past month and over one-third report pain that has persisted or recurred for >3 months (i.e., chronic pain). Accumulating evidence indicates that behavioral factors, such as alcohol use, can influence the impact of pain on health and functioning in older adults. However, most studies exploring the prevalence of alcohol use among individuals with pain have not focused on older adults, specifically. Therefore, the goal of this scoping review was to examine what is known about the prevalence of alcohol use in older adults with pain. Relevant articles published prior to April 2024 were identified through a comprehensive search strategy, developed in collaboration with content experts and a medical librarian. A total of 13 studies met inclusion criteria for this paper. Results indicated that 53-64 % of older adults with pain reported alcohol consumption, 11-28 % engaged in hazardous patterns of alcohol use, and 1-10 % had a documented alcohol use diagnosis. Moreover, there is evidence that pain severity is positively associated with likelihood of alcohol consumption among older adults. These findings are worrisome given evidence that alcohol use has been shown to lead to poorer pain outcomes, and that older adults may be at risk for experiencing detrimental alcohol-related effects at comparatively low doses, given unique challenges faced by this population (e.g., high rates of multimorbidity/polypharmacy). Collectively, findings underscore the need for enhanced assessment and treatment of alcohol use in older adults with pain.

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.

Exploring barriers and facilitators to addressing hazardous alcohol use and AUD in mental health services: a qualitative study among Dutch professionals

BACKGROUND

Hazardous alcohol use and alcohol use disorder (AUD) are highly prevalent among clients in mental health services, yet significant gaps remain in the adequate assessment of alcohol use and provision of appropriate alcohol interventions. The aim of this study was to conduct an exploration of (i) alcohol intervention elements used in mental health services and (ii) professionals' reported barriers and facilitators in identifying and intervening with hazardous alcohol use and AUD.

METHODS

Qualitative data were obtained by conducting semi-structured interviews among a purposive sample of 18 professionals from 13 different Dutch mental health services organizations (i.e., five integrated mental health organizations with addiction services, five mental health organizations without addiction services, and three addiction services organizations without mental health services). Transcripts were qualitatively analyzed using inductive thematic analysis.

RESULTS

Identified alcohol intervention elements included conducting assessments, brief interventions, treatment, referrals of clients, collaborations with other parties, and providing information to professionals. Professionals mentioned nine barriers and facilitators in the identification and intervention with hazardous alcohol use and AUD, including three aspects of professionals' behavior (i.e., professionals' agenda setting, knowledge and skills, and attitudes), actions related to identification and intervening, client contact, collaboration with other parties, and three factors in a wider context (i.e., organizational characteristics, organizational resources, and governmental aspects).

CONCLUSIONS

Although diverse alcohol intervention elements are available in Dutch mental health services, it remains unclear to what extent these are routinely implemented. To better address hazardous alcohol use and AUD in mental health services, efforts should focus on enhancing alcohol training, improving collaboration with addiction services, providing appropriate tools, and facilitating support through organizational and governmental measures.

Associations Between Divorce Histories and Unhealthy Alcohol Use Among Middle Aged and Older Adults

Background: Unhealthy alcohol use has been considered a coping strategy related to stressful and traumatic life events such as relationship loss. Yet, the effects of marital status on health behaviors are generally studied cross-sectionally or over one transition. We explored associations between the frequency and quantity of alcohol use with the number of episodes and duration of separation/divorce events across adulthood among English adults in mid to later life. Methods: This study used life history data from wave 3 (2006/07) of the English Longitudinal Study of Aging to compute marital sequences based on marital status at each year of age from 18 years of 6,355 adults aged 50-80 years. These sequences were used to compute the portion of adulthood spent separated/divorced and the number of episodes of divorce. These variables were used as predictors in logistic regressions predicting unhealthy alcohol use, while also controlling for current marital status. Results: We found that the number of episodes of separation/divorce increased the odds of drinking ≥5 days/week and binge drinking (≥6 drinks/occasion for women; ≥8 drinks/occasion for men), whereas the portion of adulthood spent divorced was not associated with drinking frequency or binge drinking. Some nuances by gender were also noted. Conclusions: Recurrent transitions into separation/divorce over adulthood appears to increase risk of unhealthy alcohol use in mid to later life beyond the risks associated with current marital status.

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.

Comorbidities, healthcare use, and contact with healthcare transition services in older veterans after incarceration

BACKGROUND

The Health Care for Reentry Veterans (HCRV) program was established to support community reintegration for veterans after incarceration. Yet, it is unclear how those with and without HCRV contact differ. We sought to evaluate differences in medical and psychiatric conditions and healthcare utilization among mid-to late-life reentry veterans who did and did not receive HCRV outreach.

METHODS

Study participants were veterans aged ≥50 years who qualified for Medicare fee-for-service, had experienced incarceration for ≥1 year, and were released from incarceration between October 1, 2006, and September 30, 2018 (N = 9733). Using VA and Medicare claims data, we compared prevalence of medical and psychiatric diagnoses, and use of emergency, inpatient, and outpatient medical and mental health services up to 12 months after release between those with and without HCRV contact.

RESULTS

Veterans with HCRV contact (35.5%) had significantly higher rates of psychiatric conditions and medical conditions related to substance use (e.g., liver disease) compared to veterans without HCRV contact. Average time between release and first healthcare service use was significantly lower for HCRV veterans (36.5 ± SD 59.5 days) versus non-HCRV veterans (58.9 ± SD 77.5 days) and HCRV veterans were more likely to utilize the emergency department, inpatient and outpatient mental health services, and inpatient medical services.

CONCLUSION

HCRV reaches older reentry veterans with a large burden of mental health and substance use disorders. However, levels of multimorbidity were high among all older reentry veterans, pointing to a need to develop specialized geriatric models of care for this reentry population.

Old tech but not low tech: telephone-based treatment provision for substance use

The future of telemedicine for substance use treatment hangs by a thread, as the United States awaits approval of proposed regulations and laws to increase care access in light of the 2022 Centers for Medicare and Medicaid Services revisions allowing for audio-only care. Telemedicine improves patient care access and outcomes. Audio-only telemedicine can be an effective and viable modality for individuals without technology resources (devices, internet services, and literacy), those with reduced telehealth service utilization (Black individuals or those with unstable housing, who are older, with low income, or with low education), and those living in rural locations. Studies suggest that telephone visits for buprenorphine treatment are well-accepted by patients and providers, making telephone visits essential in care access to reduce disparities. Telephone counseling for patients in substance use treatment is convenient, flexible, and empowering and can augment therapeutic alliances and treatment goals. Both providers and patients advocate for patient-centered hybrid care to include telephone-only treatment, which enhances service productivity and care access; reduces no-show rates, costs, and stigma; and is sustainable. Numerous solutions can expand technology access, proficiency, assimilation, and trust. Despite being "old" technology, the telephone remains an essential resource for substance use treatment.

Substance Use Screening in Geriatric Primary Care: Cultural Issues and Alcohol Consumption in the Deep South

OBJECTIVES

To investigate indicators of potentially hazardous alcohol use among older adults living in a region with high substance use stigma.

METHODS

Patients at a university-affiliated geriatrics clinic in the Deep South of theUS completed behavioral health screenings including self-reported alcohol use, symptoms of depression or anxiety, and cognitive functioning between 2018 and 2022.

RESULTS

Participants (N = 278) averaged 76.04 years of age (SD = 9.25), were predominantly female (70.9%), and non-Hispanic white (84.5%), with an averageof 6.08 comorbid diagnoses (SD = 2.86). Race/ethnicity, age, and symptoms of anxiety were associated with alcohol use and hazardous alcohol use, with non-Hispanic whites, younger individuals, and those with more anxiety symptoms reporting more alcohol use. Notably, alcohol use and hazardous alcohol use were associated with cognitive functioning in the dementia range.

CONCLUSION

Self-reported alcohol use is low in geriatric primary care in the Deep South, US, differs by race/ethnicity, and is predictive of cognitive impairment when alcohol use is hazardous. Issues of trust and stigma may play a role in self-report ofstigmatized behaviors.

CLINICAL IMPLICATIONS

Self-reported alcohol intake must be considered within the cultural context of regional stigma. Recommendations to address this are provided.

The invisible gap: Older adults' communication with health care providers about concomitant use of alcohol and medications

The purpose of this study was to assess the impact of a new educational intervention, Communicating with your Health Care Providers, which was designed to assist older adults in communicating with their physicians and other health care providers and improving their knowledge about concomitant alcohol and medication risks. A randomized control trial was conducted in older adult centers in an urban community. Participants were assigned to either the intervention group or a control group that received traditional services. The intervention group received educational material about health, physical and other aging changes, medication use and possible adverse interactions between alcohol and medications, as well as strategies to initiate communication with physicians and other health care providers. The outcomes measured were: (1) interest in communicating with physicians and health care providers; (2) perception of the importance of communication; and (3) knowledge about concomitant alcohol and medication use. MANCOVA tests indicated that the intervention group had greater knowledge about the risks of combining alcohol with prescription medications than the control group, as well as greater interest in having health care discussions with their physicians and other health care providers. These findings may be translated into future educational programming for community centers.

How older adults recovering from substance use problems experience mattering

AIM

Mattering (to feel valued and add value to self and others) is a fundamental human experience and mechanism in recovery. In this paper, we concern ourselves with the recovery of older adults with substance problems. This population is on the rise in many Western countries. To offer mattering enhancing programs for this group, more knowledge about later life mattering in service-assisted recovery processes is needed. This study aims to explore experiences of mattering in older adults receiving services to recover from substance use problems.

METHODS

A collaborative and deductive reflexive thematic approach was applied in analysing 23 interviews with participants using substance use services. Participants were recovering from different substance use problems: alcohol, medication and illegal substances. The participants were recruited from three different Norwegian social contexts: two urban and one medium size municipality. The age of the sample ranged from 65-80 years, with approximately equal numbers for those aged 60-69 (12 participants) and 70-80 (11 participants). Seven participants were women and 16 men.

RESULTS

Three main themes were identified in the analysis: "relational experiences of mattering and not mattering", "service-related experiences of mattering and not mattering" and "recovery and psychological sense of community as interrelated phenomena to experiences of mattering". The findings illustrate various nuanced experiences of mattering and not mattering in later life recovery processes.

CONCLUSIONS

Overall, the participants' mattering experiences rested on fair, healthy and positive community relationships and fair and attentive services, where participants could feel valued and also have a chance to add value to others. Experiences of not mattering were precipitated by lack of support, disrespect, devaluation and loss of relationships, and also by being ignored and not receiving fair treatment and help by professionals. Importantly, reciprocal and enhancing relations between mattering, recovery and relational PSOC seem to exist and to be significant for the older adults' access to substance use services. Several practical implications are suggested to promote the therapeutic and preventive potentials of later life mattering in recovery.

Multiple psychological senses of community and community influences on personal recovery processes from substance use problems in later life: a collaborative and deductive reflexive thematic analysis

PURPOSE

There is a pressing need for substance use services to know more about how to promote recovery from substance use problems, particularly in later life. Psychological sense of community (PSOC) is an important recovery dimension. This study aims to clarify in what ways PSOC and communities influence later life recovery processes.

METHOD

A collaborative and deductive reflexive thematic approach was used to analyse 23 interviews with older adults in recovery from different substance use problems.

RESULTS

The findings suggest that PSOC and recovery in later life include multiple communities (relational, geographical, substance use-related, ideal and service-related) and affective states (PSOC and NPSOC). Older adults' recovery, moreover, can be described as personal and heterogenic (with respect to community relationships, individual needs, type of substance use problem, age of onset and meaningful activities).

CONCLUSIONS

The findings confirm age of onset, type of substance use problem and community memberships as essential to later life recovery. They also supplement prior evidence on community resources and challenges to later life recovery. Importantly, the new findings extend and nuance current understandings of later life recovery. Taken together, the article illustrates MPSOC as a useful concept, with central practical and theoretical implications for later life recovery.

Evolving Profile of Acute Spinal Cord Injury Demographics, Outcomes, and Surgical Treatment in North America: Analysis of a Prospective Multi-Center Dataset of 989 Patients

Changes in demography and injury patterns have altered the profile and outcome of acute spinal cord injury (SCI) over time. This study sought to describe recent trends in epidemiology and early clinical outcomes using the multi-center North American Clinical Trial Network (NACTN) for Spinal Cord Injury Registry. All participants with blunt acute traumatic SCI (n = 782) were grouped into three five-year time intervals from 2005 to 2019 (2005-2009, 2010-2014, and 2015-2019). Baseline demographics, clinical scores, medical co-morbidities, as well as early clinical outcomes were extracted. Categorical and continuous variables were analyzed to determine between-group differences. Subgroup analysis was performed for participants <50 and ≥50 years of age. Over the duration of the study period, there was an increase in age at presentation (p = 0.0077) as well as a greater incidence of falls as the mechanism of injury. Participants who were ≥50 years of age were more likely to sustain incomplete SCI (<0.0003) and central cord syndrome (< 0.0001). In the most recent period (2015-2019), a greater proportion of NACTN participants underwent surgery within 24 h of injury (63% vs. 41% vs. 41%, p = 0.0001). There was a statistically significant increase in cardiac complications (p < 0.0001) and decrease in pulmonary complications (p < 0.0001) during the study period. Data from the NACTN registry shows that the age of participants with acute SCI is increasing, falls have become the major mechanism of injury, and central cord injury is becoming increasingly prevalent. While early surgical intervention for acute SCI is more common in recent years, cardiac complications are more prevalent while pulmonary complications are less prevalent.

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

Purpose of review

Substance use disorders are becoming increasingly prevalent in the geriatric population, necessitating an updated understanding of the existing literature. This review aims to describe the epidemiology, special considerations, and management of substance use disorders in older adults.

Recent findings

PubMed, Ovid MEDLINE, and PsychINFO databases were searched from their inception through June 2022 using the following keywords: "substance use disorder," "substance abuse," "abuse," "illicit substances," "illicit drugs," "addiction," "geriatric," "elderly," "older adults," "alcohol," "marijuana," "cannabis," "cocaine," "heroin," "opioid," and "benzodiazepine." Our findings suggest an increasing trend in substance use in older adults despite medical and psychiatric consequences when using such substances. The majority of older patients admitted to substance abuse treatment programs were not referred by healthcare providers, suggesting room for improvement in the screening and discussion of substance use disorders. Our review also suggests that there should be careful consideration of COVID-19 and racial disparities when screening, diagnosing, and treating substance use disorders in the older population.

Summary

This review provides updated information on epidemiology, special considerations, and management of substance use disorders in older adults. As substance use disorders become more prevalent in older adults, primary care physicians must be prepared to recognize and diagnose substance use disorders as well as collaborate with and refer patients to geriatric medicine, geriatric psychiatry, and addiction medicine.

The role of substance use in the lives of incarcerated older adults: A qualitative study

Background

The prevalence of drug abuse among older adults has grown over the last decade. Despite the expanding development of a body of research dedicated to studying this phenomenon, drug abuse by incarcerated older adults has been marginalized. Thus, the aim of the present study was to explore drug abuse patterns in the lives of incarcerated older adults.

Method

Semi-structured interviews were conducted with 28 incarcerated older adults, and an interpretive analysis was used to analyze the participants’ narratives.

Findings

Four themes emerged: (1) Growing up around drugs; (2) Prison onset; (3) Professionals, and (4) Lifelong substance abuse.

Conclusion

The study findings reveal a unique typology of drug-related themes in the lives of incarcerated older adults. This typology sheds light on the interplay between aging, drug use, and incarceration and the way these three socially marginalized positions may intersect.

Evidence-based Treatment for Substance Use Disorders in Community Mental Health Centers: the ACCESS Program

A significant gap remains in the availability and accessibility of evidence-based treatments (EBTs) in community substance use disorder (SUD) treatment. This study describes a 2-year statewide training initiative that sought to address this gap by training community-based therapists in motivational enhancement/cognitive behavioral therapy (MET/CBT). Therapists (N = 93) participated in a 2-day MET/CBT workshop followed by bi-weekly clinical consultation, fidelity monitoring, guided readings, and online resources. Therapists completed pre-training and follow-up assessments measuring knowledge, attitudes, confidence, and implementation barriers. Most therapists attended 10 or more consultation calls. Submission of session recordings for feedback was the least utilized training element. Therapists reported increased confidence in their ability to implement MET/CBT for SUD and demonstrated improvement in MI and CBT knowledge. Therapists reported several implementation barriers, including lack of time and opportunity to treat patients with MET/CBT. Recommendations for future training initiatives and addressing the barriers identified in this study are discussed.

Substance Use Disorders in the Elderly

The population of elderly in the United States with substance use disorders (SUDs) is growing appreciably. SUDs among the elderly are often associated with poor outcomes and are frequently underdiagnosed. The current diagnostic criteria are less sensitive in identifying SUDs among the elderly. Routine screening with validated screening tools may improve the diagnosis of SUDs among the elderly. There is a dearth of data from controlled studies on SUDs among the elderly and the use of pharmacologic agents for treatment, although data indicate that older adults with SUDs respond well to treatments that are specifically designed for this age group.

Older Adult Substance Use Treatment First-Time Admissions Between 2008 and 2018

OBJECTIVES

To see whether the percentage of older adults entering substance use treatment for their first time continued to increase and whether there were changes in the use patterns leading to the treatment episode, particularly an increase in illicit drugs.

DESIGN

Public administrative health record study.

SETTING

The Treatment Episode Data Sets publicly available from the Substance Abuse Mental Health Services Administration from 2008 to 2018.

PARTICIPANTS

Young adults age 30-54 years (N = 3,327,903) and older adults age 55 years and older (N = 453,598) with a first-time admission for a publicly funded substance use treatment.

MEASUREMENTS

Demographic and substance use history variables at admission.

RESULTS

The proportion of older adults going for substance use treatment for the first time continued to increase between 2008 and 2018 relative to younger adults, continuing the trend of increasing first-time admission between 1998 and 2008. For the first time, the primary substance at admission for older adults was an illicit substance only, surpassing alcohol only and the combination of alcohol and illicit drug use. In this period, use of opioids, particularly heroin, and methamphetamine increased among older adults entering treatment.

CONCLUSIONS

As our population ages and substance use trends change, healthcare providers that take care of older adults must have skills to prevent, screen for, diagnose, and treat substance use disorders. Given recent trends in substance use and treatment among older adults, substance use treatment programs must adapt to meet the needs of an older population.

Substance Use Disorders in Postacute and Long-Term Care Settings

Substance use disorders (SUDs) have not been rigorously studied in postacute and long-term care (PALTC) populations. SUDs are among the fastest growing disorders in the community dwelling older population. Untreated SUDs often lead to overdose deaths, emergency department visits, and hospitalizations due to SUD-related adverse effects, especially exacerbation of comorbid physical and mental health conditions. Primary care providers (PCPs) working in PALTC settings can and should play a key role in its prevention and treatment. This clinical review identifies several practical strategies that PCPs can incorporate in their daily practice to improve lives of PALTC population having SUD.

Birth order and health events attributable to alcohol and narcotics in midlife: A 25-year follow-up of a national Swedish birth cohort and their siblings

Higher birth order is associated with increased risks of adverse health outcomes attributable to alcohol or narcotics in adolescence, but it remains unclear whether these observed birth order effects are also present in midlife. Drawing on a national Swedish cohort born in 1953 and their siblings, we estimate associations between birth order and alcohol- or narcotics-attributable hospitalization or death with a 25-year follow-up to assess whether birth order differences are observed during this life course period. Health events attributable to alcohol or narcotics use were identified using the Swedish National Patient and Cause of Death registers, respectively. We apply Cox proportional hazards models to estimate average birth order differences in hazards for alcohol- or narcotics-attributable hospitalization or death between ages 30 and 55. We estimate birth order differences between families, and use two fixed-effects approaches to estimate birth order differences within families and within families of the same type. Bivariate results indicate increased hazards for both outcomes with higher birth order; however, these results are no longer observed after adjustment for familial background characteristics in all models. Our results thereby show limited evidence for birth order differences in midlife. This study highlights that shared factors within the family of origin may be stronger predictors of adverse health outcomes attributable to substance use among siblings during this life course period. Future research should disentangle the contributions of the social environment within the family of origin for adverse health outcomes attributable to alcohol or narcotics among siblings.

•

We estimate birth order differences for alcohol or narcotics use outcomes between ages 30-55.

•

Birth order differences are not observed for alcohol- or narcotics-attributable events in midlife.

•

Family background characteristics may be stronger predictors of these outcomes.

Associations between sleep patterns, smoking, and alcohol use among older adults in Canada: Insights from the Canadian Longitudinal Study on Aging (CLSA)

Poor sleep is associated with chronic health conditions among older adults. As substance use rates increase in this population, age-related physiological and cognitive declines may exacerbate its detrimental consequences, including sleep problems. We analyzed cross-sectional associations between sleep patterns, smoking, and alcohol use using baseline data from 30,097 community-dwelling Canadian adults aged 45-85 years from the Canadian Longitudinal Study on Aging. Insomnia symptoms (difficulties falling/staying asleep), sleep duration (short:<6h; long:>8h), and sleep satisfaction(dissatisfied/neutral/satisfied) were measured. Smoking and alcohol-use frequency (past 12 months), average daily amount (past 30 days), and binge drinking (past 12 months) were self-reported, and associations were examined using modified Poisson regression. Approximately 23% of participants had insomnia symptoms, and 26% reported sleep dissatisfaction. 91% of participants were current non-smokers, whereas 7% reported smoking daily. Over 50% drank ≤ 2 drinks daily, and 3% reported binge drinking. There was a higher adjusted prevalence of insomnia among daily smokers (PR = 1.10, 95% CI = 1.00-1.21) and binge drinkers (PR = 1.21, 95% CI = 1.02-1.43). Odds of short sleep duration were lower among regular drinkers (COR = 0.71, 95% CI = 0.56-0.90) and higher among daily smokers (COR = 1.19, 95% CI = 1.01-1.40). Heavy and frequent smoking and alcohol use are associated with both insomnia symptoms and sleep dissatisfaction, but not consistently with sleep duration. Further longitudinal investigation of this relationship in aging populations is needed in clinical and public health settings to infer the extent of causality and design effective public health interventions in this vulnerable population.

A Prospective Randomized Controlled Trial of Methylprednisolone for Postoperative Pain Management of Surgically Treated Distal Radius Fractures

PURPOSE

Perioperative glucocorticoids have been effectively used as a pain management regimen for reducing pain after hand surgery. We hypothesize that a methylprednisolone taper (MPT) course following surgery will reduce pain and opioid consumption in the early postoperative period.

METHODS

This study was a randomized controlled trial of patients undergoing surgical fixation for distal radius fracture. Before surgery, patients were randomly assigned to receive preoperative dexamethasone only or preoperative dexamethasone followed by a 6-day oral MPT. Patient pain and opioid consumption data were collected for 7 days after surgery using a patient-reported pain journal.

RESULTS

Our study consisted of 56 patients enrolled from November 2018 to March 2020. Twenty-eight patients each were assigned to the control and treatment groups. Demographic characteristics such as age, body mass index, the dominant side affected, smoking status, diabetes status, and current narcotic use were similar between the control and treatment groups. With a noticeable, significant reduction starting on postoperative day 2, patients who received an MPT course consumed substantially less opioids during the first 7 days (7.8 ± 7.2 pills compared with 15.5 ± 11.5 pills, a 50% reduction). These patients also consumed significantly fewer oral morphine equivalents than the control group (81.2 vs 41.2). A significant difference in the pain visual analog scale scores between the 2 groups was noted starting on postoperative day 2, with 48% of the treatment group reporting no pain by postoperative day 6. No adverse events, including infection or complications of wound or bone healing, were seen in either group.

CONCLUSIONS

There was an early improvement in pain and reduction in early opioid consumption with a 6-day MPT following surgical fixation for distal radius fracture. With no increased risk of adverse events in our sample, MPT may be a safe and effective way to reduce postoperative pain.

Drug Use among the Elderly Assisted by the Psychosocial Assistance Center in District Federal-Brasilia

The inadequate and abusive usage of psychoactive substances is something real that affects Brazil’s elderly population, and it is a huge challenge for the public health system and its professionals. Aware of the social impact involving the use of illegal drugs, in 2002, the Ministry of Health instituted a network of psychosocial assistance as a strategy to deal with the problem. This study carried out an analysis of the profile of use of legal and illegal drugs by the elderly who are assisted by the network of psychosocial assistance in the Federal District. A quantitative and analytical study with secondary data collection, using patient records held in the CAPS-AD in the Federal District. The inclusion criteria were people of 60 and over who were users of alcohol and other drugs and who sought assistance at CAPS-AD between 2000 and 2017. A total of 408 medical records were analyzed concerning social demographic variations, types of rehabilitation services sought, types of substances consumed, associations between drugs consumed, time of consumption, and adherence to the treatment. Most of the elderly users were male (85.3%), on average 64 ± 4.42 years old. Regarding the drugs consumed, the highest quantity was for illegal substances (76%), compared to the legal ones (23%). No significant difference was found between males (OR = 1.1) and females (OR = 0.74) regarding the use or abuse of multiple drugs. The elderly used both legal and illegal drugs for a long period of time, with low adherence to the treatment, and alcohol consumption among the elderly prevailed above the other psychoactive substances.

Chronic health conditions, acute health events, and healthcare utilization among adults over age 50 in Hawai'i who use cannabis: A matched cohort study

BACKGROUND

Research on cannabis-related health outcomes in diverse older adults is limited. The current study utilized a matched cohort study design to compare older adults in Hawai'i with identified cannabis diagnoses and matched controls on chronic health conditions, acute health events, and healthcare utilization from 2016 to 2020.

METHOD

Patients age 50 + were identified using ICD-10 diagnostic codes for cannabis use, abuse, and dependence using electronic health record data from an integrated health system (Kaiser Permanente Hawai'i). Those with cannabis diagnoses (n = 275) were compared to matched non-using controls (n = 275; based on age, sex) on chronic health conditions (coronary heart disease, hypertension, COPD, chronic non-cancer pain), acute health events (myocardial infarction, respiratory symptoms, stroke, persistent or cyclic vomiting, injuries), and healthcare utilization (outpatient, inpatient, and emergency department visits) following case identification for two years.

RESULTS

Participants were 19.3% Native Hawaiian/Pacific Islander, 24.4% Asian, 47.8% White, and 8.5% Other/Unknown, with an average age of 62.8 years (SD=7.3). Adjusting for covariates as possible, participants with a cannabis diagnosis had significantly greater risk of coronary heart disease, chronic non-cancer pain, stroke, myocardial infarction, cyclic vomiting, and injuries, over time, compared to controls. Cannabis use was associated with any and greater frequency of outpatient, inpatient, and emergency department visits.

CONCLUSIONS

In a diverse sample, older adults who used cannabis had worse health conditions and events and used more health services over a two-year period. Future studies should evaluate cannabis-related health outcomes, effects of cannabis problem severity, as well as implications for healthcare in aging populations.

Are Essential Trace Elements Effective in Modulation of Mental Disorders? Update and Perspectives

The emergence of mental disorders is associated with several risk factors including genetic and environmental susceptibility. A group of nutrients serves an especially important role in a number of essential neurodevelopmental processes through brain areas promoting the high degree of brain metabolism during early life, although almost all nutrients are needed. These include macronutrients and micronutrients (e.g., iron, magnesium, zinc, copper, selenium). Numerous nutritional psychiatry trials have been performed to examine the correlation of many individual nutrients with mental health, such as essential trace elements. The increased accumulation or lack of such components will facilitate an alternative metabolic pathway that can lead to many diseases and conditions of neurodevelopment. Mental functions have biochemical bases, so the impairment of such neurochemical mechanisms due to lack of trace elements can have mental effects. In psychological conditions such as depression, anxiety, schizophrenia, and autism, scientific studies demonstrate the putative role of trace element deficiency. Therefore, given the critical roles played by essential trace elements in the neurodevelopment and mental health, the effect of these elements' intake on the modulation of psychological functioning is reviewed.

Characteristics of Mental Health and Substance Use Service Facilities for Older Adults: Findings from U.S. National Surveys

OBJECTIVES

To describe the characteristics of U.S. mental health and substance use service programs dedicated/tailored for older adults (age 65+).

METHODS

Data came from the 2012 and 2019 National Mental Health Services Survey (N-MHSS) and the National Survey of Substance Abuse Treatment Services (N-SSATS). Using Pearson χ2 and Fisher's exact tests, we compared the numbers/proportions of older-adult programs in 2012 and 2019 and examined differences between facilities with or without an older-adult program in 2019.

RESULTS

From 2012 to 2019, the percent of all mental health and substance use service facilities for adults that had a dedicated/tailored program for older adults increased significantly, from 20.7% to 28.9% for mental health facilities and from 7.1% to 24.8% for substance use facilities, with 101 mental health facilities and 53 substance use facilities serving older adults exclusively in 2019. Compared to facilities without an older-adult program, higher percentages of facilities with such a program offered treatment for co-occurring mental and substance use disorders and supplemental health and social care services.

CONCLUSIONS

Given the rapidly aging society, more accessible and affordable programs dedicated/tailored for older adults are needed. To achieve this goal and better meet older adults' needs, more detailed data on facility characteristics are needed to build the knowledge base on improving the treatment environment.

CLINICAL IMPLICATIONS

Programs for older adults should be designed to meet the complex needs of those with mental health and/or substance use problems and incorporate innovative service delivery models that can improve older adults' access.

Age, period, and cohort effects on trends in outpatient addiction care utilization in the general Berlin population from 2008 to 2016

Background

The aim of this study was to decompose independent effects of age, period, and cohort on trends in outpatient addiction care utilization resulting from alcohol (AUD) and illicit substances use disorders (ISUD). Decomposing trends in addiction care utilization into their independent effects by age, period, and cohort may lead to a better understanding of utilization patterns.

Methods

Individuals seeking help in Berlin outpatient addiction care facilities between 2008 and 2016 with an age range of 18–81 years for AUD (n = 46,706) and 18–70 years for ISUD (n = 51,113) were standardized to the general Berlin population using data from the German Federal Statistical Office. Classification of utilization as AUD- (F10) or ISUD-related (F11, F12, F14, F15, F16, F18, F19) help-seeking was based on primary diagnoses according to the International Statistical Classification of Diseases and Related Health Problems. Age was measured in years and period as year of data collection. Cohort was defined as the mathematical difference between period and age. Age, period, and cohort analyses were conducted using the intrinsic estimator model on AUD- and ISUD-related outpatient addiction care utilization.

Results

Age effects on AUD-related utilization were highest in 18- to 19-year-old and in 39- to 59-year-old individuals. ISUD-related utilization declined almost continuously with increasing age. Period effects on AUD- and ISUD-related utilization were small. AUD-related utilization was highest in cohorts born from 1951 to 1986. ISUD-related utilization increased in cohorts born between 1954 and 1973 where utilization peaked, followed by a decline of the same order.

Conclusions

Age and cohort effects were the strongest drivers of trends in AUD- and ISUD-related outpatient addiction care utilization. Onset of help-seeking in earlier phases of AUD development should be enhanced as well as help-seeking for AUD and ISUD in general. The highest cohort-related rates in the baby boomer and following cohorts for AUD and ISUD underline an increased demand for addiction care.

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.

The Association of Preoperative Opioid Use With Revision Surgery and Complications Following Carpometacarpal Arthroplasty

PURPOSE

Preoperative opioid use has been shown to be associated with poor outcomes following different upper-extremity surgeries. We aimed to examine the relationship between preoperative opioid use and outcomes following carpometacarpal (CMC) arthroplasty. We hypothesized that patients prescribed higher daily average numbers of preoperative oral morphine equivalents (OMEs) would show higher rates of complications and revision surgery.

METHODS

In the Truven Health MarketScan Database, we identified all patients who underwent CMC arthroplasty from 2009 to 2018. We separated them into cohorts based on average daily OMEs prescribed in the 6 months prior to the surgery: opioid naïve, <2.5, 2.5 to 5, 5 to 10, and >10 OMEs per day. We retrieved 90-day complications and 3-year revision surgery data, and we compared these outcomes by opioid-use groups.

RESULTS

We identified 40,141 patients. The majority (55.9%) were opioid naïve, with the next most common group receiving a daily average of <2.5 OMEs (19.2%). Complications increased with increased preoperative OMEs. Multivariable analysis revealed that patients taking >10 OMEs per day had a 1.45% increase in 3-year revision surgery compared with opioid-naïve patients, which equated to 2.12 (confidence interval [CI]: 1.33-3.36) times increased odds. Additionally, patients taking >10 OMEs had increased odds of an emergency department visit (odds ratio [OR]: 1.60, CI: 1.43-1.78), a 90-day hospital admission (OR: 2.34, CI: 1.97-2.79), and surgical site infection (OR, 2.02, CI: 1.59-2.54) compared with opioid-naïve patients, with absolute differences of 4.53%, 2.78%, and 1.22% compared with opioid-naïve patients, respectively. Additionally, preoperative opioid use predicted both number of prescriptions filled in the short term and long term continued opioid use.

CONCLUSIONS

Preoperative opioid use of >10 OMEs per day is associated with a higher risk for complications and revision surgery following CMC arthroplasty. Our findings demonstrate a dose-dependent relationship between opioid use and postoperative complications. Further study is necessary to determine if reducing opioid use prior to CMC arthroplasty may reduce the likelihood of these negative outcomes.

Evaluation and Management of Alcohol use Disorder among Older Adults

Purpose of Review

The prevalence of alcohol use disorder (AUD) among older adults in the United States is rising, but remains underdiagnosed, underreported, and inadequately managed. This review highlights the medical, social, and cultural factors of AUD in older adults and provides guidelines for its screening, evaluation, and management.

Recent Findings

The COVID-19 pandemic has created additional challenges and barriers to care, as older adults may have disproportionate worsening of anxiety, depression, and substance use resulting from increased isolation related to physical distancing and shelter-in-place guidelines.

Summary

All older adults should be routinely screened for AUD with standardized screening tools. If a patient’s screening results are positive, a clinician should conduct a brief assessment, which may be supplemented by laboratory tests. Most older adults at risk for alcohol misuse do not need specialized SUD treatment, but most can benefit from Screening, Brief Intervention, and Referral to Treatment (SBIRT) to prevent substance misuse before it occurs. Medications for the treatment of AUD in older adults include naltrexone, acamprosate, disulfiram, gabapentin and topiramate. Psychosocial treatments, including mutual help groups, are equally important.

Preoperative opioid use is an independent risk factor for complication, revision, and increased health care utilization following primary total shoulder arthroplasty

INTRODUCTION

The incidence of total shoulder arthroplasty (TSA) in increasing. Evidence in primary hip and knee arthroplasty suggest that preoperative opioid use is a risk factor for postoperative complication. This relationship in TSA is unknown. The purpose of this study was to investigate this relationship.

METHODS

The Truven Marketscan claims database was used to identify patients who underwent primary, unilateral TSA. Preoperative opioid use status was then used to divide patients into cohorts based on the average daily oral morphine equivalents (OMEs) received in the 6-month preoperative period. This included the following cohorts: opioid naïve and <1, 1-5, 5-10, and >10 average daily OMEs. In total, 29,454 patients with 90-day postoperative follow-up were included. Of these, 21,580 patients and 8959 patients had 1- and 3-year follow-up, respectively. Patient information and complication data were collected. Univariate and multivariate logistic regression were then performed to assess the association of preoperative opioid use with postoperative outcomes. A subgroup analysis was performed to examine revision surgery at 1 and 3 years postoperatively.

RESULTS

Forty-four percent of identified patients received preoperative opioids, but the preoperative opioid-naïve patient became more common over the study period. Multivariate analysis demonstrated that patients receiving >10 average daily OMEs (compared with opioid naïve) had higher odds of opioid overdose (odds ratio [OR] 4.17, 95% confidence interval [CI] 1.57-11.08, P = .004), wound complication (OR 2.04, 95% CI 1.44-2.89, P < .001), superficial surgical site infection (OR 2.33, 95% CI 1.63-3.34, P < .001), prosthetic joint infection (OR 3.41, 95% CI 2.50-4.67, P < .001), pneumonia (OR 1.95, 95% CI 1.39-2.75, P < .001), and thromboembolic event (OR 1.42, 95% CI 1.18-1.72, P < .001). The same group had higher health care utilization, including extended length of stay, nonhome discharge, readmission, and emergency department visits (P ≤ .001). Total perioperative adjusted costs were more than $7000 higher in the >10-OME group when compared to preoperative opioid-naïve patients.

DISCUSSION

Opioid use prior to TSA is common and is associated with increased complications, health care utilization, revision surgery, and costs. This risk is dose dependent, and efforts should be made at cessation prior to surgery.

Late- and Typical-Onset Heroin Use Among Older Adults Seeking Treatment for Opioid Use Disorder

OBJECTIVE

Analyze 10-year trends in opioid use disorder with heroin (OUD-H) among older persons and to compare those with typical-onset (age <30 years) to those with late (age 30+) onset.

DESIGN

Naturalistic observation using the most recent (2008-2017) Treatment Episode Data Set-Admissions (TEDS-A).

SETTING

Admission records in TEDS-A come from all public and private U.S. programs for substance use disorder treatment receiving public funding.

PARTICIPANTS

U.S. adults aged 55 years and older entering treatment for the first time between 2008 and 2017 to treat OUD-H.

MEASUREMENTS

Admission trends, demographics, substance use history.

RESULTS

The number of older adults who entered treatment for OUD-H nearly tripled between 2007 and 2017. Compared to those with typical-onset (before age 30), those with late-onset heroin use were more likely to be white, female, more highly educated, and rural. Older adults with late-onset were more likely to be referred to treatment by an employer and less likely to be referred by the criminal justice system. Those with late-onset were more likely to use heroin more frequently but less likely to inject heroin than those with typical-onset. Those with typical onset were more likely to receive medication for addiction treatment than those with late-onset.

CONCLUSION

Late-onset heroin use is increasing among older U.S. adults. Research is needed to understand the unique needs of this population better. As this population grows, geriatric psychiatrists may be increasingly called upon to provide specialized care to people with late-onset OUD-H.

Low Back Pain and Substance Use: Diagnostic and Administrative Coding for Opioid Use and Dependence Increased in U.S. Older Adults with Low Back Pain

OBJECTIVE

Low back pain (LBP) is a leading cause of pain and disability. Substance use complicates the management of LBP, and potential risks increase with aging. Despite implications for an aging, diverse U.S. population, substance use and LBP comorbidity remain poorly defined. The objective of this study was to characterize LBP and substance use diagnoses in older U.S. adults by age, gender, and race.

DESIGN

Cross-sectional study of a random national sample.

SUBJECTS

Older adults including 1,477,594 U.S. Medicare Part B beneficiaries.

METHODS

Bayesian analysis of 37,634,210 claims, with 10,775,869 administrative and 92,903,649 diagnostic code assignments.

RESULTS

LBP was diagnosed in 14.8±0.06% of those more than 65 years of age, more in females than in males (15.8±0.08% vs. 13.4±0.09%), and slightly less in those more than 85 years of age (13.3±0.2%). Substance use diagnosis varied by substance: nicotine, 9.6±0.02%; opioid, 2.8±0.01%; and alcohol, 1.3±0.01%. Substance use diagnosis declined with advancing age cohort. Opioid use diagnosis was markedly higher for those in whom LBP was diagnosed (10.5%) than for those not diagnosed with LBP (1.5%). Most older adults (54.9%) with an opioid diagnosis were diagnosed with LBP. Gender differences were modest. Relative rates of substance use diagnoses in LBP were modest for nicotine and alcohol.

CONCLUSIONS

Older adults with LBP have high relative rates of opioid diagnoses, irrespective of gender or age. Most older adults with opioid-related diagnoses have LBP, compared with a minority of those not opioid diagnosed. In caring for older adults with LBP or opioid-related diagnoses, health systems must anticipate complexity and support clinicians, patients, and caregivers in managing pain comorbidities. Older adults may benefit from proactive incorporation of non-opioid pain treatments. Further study is needed.

A narrative review of highly processed food addiction across the lifespan

Evidence is growing that highly processed (HP) foods (i.e., foods high in refined carbohydrates and fat) are highly effective in activating reward systems and may even be capable of triggering addictive processes. Unlike traditional drugs of abuse, exposure to HP foods is common very early in development. HP food addiction has been associated with negative outcomes, including higher body mass index (BMI), more frequent binge eating, greater failure in weight loss treatment trials, and poorer mental and physical health. Although most research on HP food addiction has been conducted using adult samples, research on this topic now spans across the life span beginning in utero and extending through older adulthood. HP food addiction and related reward-based changes are associated with negative outcomes at every life stage, which has important implications for developmentally tailored prevention and treatment efforts. Using a developmentally informed approach, the current study comprehensively reviews the existing research on HP food addiction across the lifespan and highlights important areas of future research.

Testing Relationships Between Racial-Ethnic Identity, Racial-Ethnic Discrimination, and Substance Misuse Among Black and Latinx Older Adults in a Nationally Representative Sample

Older adults (aged 55+) comprise a rapidly growing population both in number and racial-ethnic diversity. In recent years, substance misuse prevalence among older adults has increased and is expected to continue rising, highlighting the need to understand risk and protective factors in this population. Using nationally representative data, this study examines the association of racial-ethnic identity and racial-ethnic discrimination with alcohol and illicit drug use among Black and Latinx older adults, and whether racial-ethnic identity moderates the relationship between discrimination and substance misuse. Findings show that among Latinx older adults discrimination is associated with increased substance misuse, and higher ethnic identity is associated with decreased illicit drug use. Higher racial-ethnic identity buffers the effects of discrimination on illicit drug use for Latinx, but not for Black respondents. Findings of this study highlight the complex associations between racial-ethnic identity, discrimination, and substance misuse, varying across racial-ethnic group, age, context, and other factors.

The Potential Contribution of Chronic Pain and Common Chronic Pain Conditions to Subsequent Cognitive Decline, New Onset Cognitive Impairment, and Incident Dementia: A Systematic Review and Conceptual Model for Future Research

BACKGROUND

Growing evidence suggests that chronic pain and certain chronic pain conditions may increase risk for cognitive decline and dementia.

OBJECTIVE

In this systematic review, we critically evaluate available evidence regarding the association of chronic pain and specific common chronic pain conditions to subsequent decline in cognitive function, new onset cognitive impairment (CI), and incident Alzheimer's disease and related dementias (ADRD); outline major gaps in the literature; and provide a preliminary conceptual model illustrating potential pathways linking pain to cognitive change.

METHODS

To identify qualifying studies, we searched seven scientific databases and scanned bibliographies of identified articles and relevant review papers. Sixteen studies met our inclusion criteria (2 matched case-control, 10 retrospective cohort, 2 prospective cohort), including 11 regarding the association of osteoarthritis (N = 4), fibromyalgia (N = 1), or headache/migraine (N = 6) to incident ADRD (N = 10) and/or its subtypes (N = 6), and 5 investigating the relation of chronic pain symptoms to subsequent cognitive decline (N = 2), CI (N = 1), and/or ADRD (N = 3).

RESULTS

Studies yielded consistent evidence for a positive association of osteoarthritis and migraines/headaches to incident ADRD; however, findings regarding dementia subtypes were mixed. Emerging evidence also suggests chronic pain symptoms may accelerate cognitive decline and increase risk for memory impairment and ADRD, although findings and measures varied considerably across studies.

CONCLUSION

While existing studies support a link between chronic pain and ADRD risk, conclusions are limited by substantial study heterogeneity, limited investigation of certain pain conditions, and methodological and other concerns characterizing most investigations to date. Additional rigorous, long-term prospective studies are needed to elucidate the effects of chronic pain and specific chronic pain conditions on cognitive decline and conversion to ADRD, and to clarify the influence of potential confounding and mediating factors.

Reminiscence in the Face of Death of a Filipino Elderly With Substance Use Disorder: The Case of Burt

Death is an important reality that the elderly face. In preparation for death, old people engage in reminiscence. However, the presence of addiction in the elderly may influence this process. The current study examined the life of Burt, a sixty-five year old man with substance use disorder, his reflections on death, and the different types of reminiscence he uses. Using a case study, six themes were uncovered. Burt's reflections on death revealed his awareness of his death, how he plans to spend his dying days, and his idea of a symbolic death by losing his loved ones. Burt engages in reminiscence patterns that are composed of identity recollections, life milestones, and painful experiences. These themes were examined in order to understand how an elderly person with addiction prepares for his own death. Research limitations, recommendations, and implications in clinical practice and human development research are also discussed.

Substance use disorders: diagnosis and management for hospitalists

Substance use disorder is a significant health concern. Hospitalists manage patient with various forms of substance use disorder on a daily basis. In this review, we have tried to synthesize evidence together to give a brief, yet succinct, review of commonly encounters disorders; alcohol intoxication and withdrawal, opioid intoxication and withdrawal, cocaine intoxication and methamphetamine intoxication. We describe clinical features, diagnosis and management, which would serve as a great resource for hospitalist when managing these complicated patients.

The Impact of Preoperative Opioid Use Disorder on Complications and Costs following Primary Total Hip and Knee Arthroplasty

Introduction

Multiple studies have demonstrated that patients taking opioids in the preoperative period are at elevated risk for complications following total hip (THA) and knee (TKA) arthroplasty. However, the incidence and impact of opioid use disorder (OUD) among these patients—both clinically and fiscally—remain unknown. The purpose of this study was to investigate this relationship.

Methods

The Nationwide Readmission Database (NRD) was used to identify patients undergoing THA and TKA from 2011 to 2015. Coarsened exact matching was used to statistically match the OUD and non-OUD cohorts. Further analysis was then conducted on matched cohorts with multivariate analysis. The incidence of OUD was also determined, and the costs associated with this comorbidity were calculated.

Results

The incidence of OUD in arthroplasty patients increased 80% over the study period. OUD patients had higher odds of prosthetic joint infection (OR 1.55, 95% CI 1.23–1.94), wound complication (OR 1.40, 95% CI 1.12–1.76), prosthetic complication (OR 1.37, 95% CI 1.10–1.70), and revision surgery (OR 1.47, 95% CI 1.19–1.81). OUD patients also had longer length of stays (TKA: +0.67 days; THA: +1.09 days), higher readmission (OR 1.60, 95% CI 1.43–1.79), and increased 90-day costs (TKA: +$3,602 [95% CI $3,138–4,065]; THA: +4,527 [95% CI $3,593–4,920).

Conclusion

Opioid use disorder is becoming a more common comorbidity among THA and TKA patients. This is concerning as it represents a significant risk factor for postoperative complication. It additionally confers increased perioperative costs. Patients with OUD should be counseled on their elevated risk, and future work will be needed to determine if this is a modifiable risk factor.
