Intentional benzodiazepine poisoning in older adults reported to United States Poison Centers.

INTRODUCTION: Despite known contraindications, benzodiazepines are frequently prescribed for older adults. This study utilizes poison control center data on benzodiazepine-involved cases aged 50 and above to compare the characteristics of suspected suicide attempt with other intentional misuse cases. We also examined associations of major medical outcomes (major effect/death) with demographic characteristics and other co-used substances in each group. METHODS: The study employed data from the America's Poison Center National Poison Data System from 2015-2022. Descriptive statistics and binary logistic regression models were used. RESULTS: Of the benzodiazepine-poisoning cases of intentional misuse (n = 93,245), 85 percent were suicide attempts and 15 percent were other intentional misuses. Reports to poisons centers showed a decline from 2019-2022 when compared to 2015-2016. However, the likelihood of a reported suicide attempt, compared to other intentional misuse, was greater in 2019-2022 compared to 2015-2016 and among those who co-used antidepressants, anxiolytics, atypical antipsychotics, other benzodiazepines, other analgesics, anticonvulsants, and alcohol. The odds of major effect/death in both groups were also greater in 2019-2022, with suicide attempt cases in advanced ages showing higher odds. The co-use of antidepressants, prescription opioids, atypical antipsychotics, anticonvulsants, and other analgesics were associated with a higher likelihood of major effect/death in both exposure groups. For instance, adjusted odds ratios for co-used prescription opioids were 2.20 (95 percent confidence intervals: 2.09-2.31) among suicide attempt cases and 3.51 (95 percent confidence intervals: 3.10-3.97) among other intentional misuse cases. DISCUSSION: Healthcare providers need to screen for suicidal ideation among benzodiazepine users, with special attention to an increased risk of suicide attempt among those who co-use antidepressants and opioids and to decreasing adverse outcomes in all misuse cases. Assessments of underlying mental health and substance use problems and medication regimens to minimize polypharmacy and drug interactions are needed to reduce adverse outcomes. CONCLUSIONS: Though the numbers of benzodiazepine-involved suicide attempt and other intentional misuse cases reported to United States poison centers decreased in recent years, the likelihood of major medical effect/death among these cases have increased.

Mediation of the Association Between Physical Exercise and Depressive/Anxiety Symptoms by Pain and Sleep Problems Among Older Adults.

In this study, based on the 2022 National Health and Aging Trend Study (N = 5,593, age 65+), we examined direct associations between moderate and vigorous physical exercise (PE) and depressive/anxiety symptoms as well as bothersome pain and sleep problems. We then examined if the association between PE and depressive/anxiety symptoms would be partially mediated by the effects of PE on bothersome pain and sleep problems. Results from a path model showed that controlling for sociodemographic and health statuses, PE was negatively associated with depressive/anxiety symptoms and bothersome pain, but it was not significantly associated with sleep problems. The mediation analysis showed that 10% of the total effects of PE on depressive/anxiety symptoms was indirect effects of PE on bothersome pain. This study is important as it examined the associations among PE, pain, sleep, and depression/anxiety in community-dwelling older adults in their natural environments. Healthcare and social service providers for older adults need to emphasize the importance and benefits of PE for older adults' physical and mental health. Easy access to venues for PE is also important.

Healthcare Cost Burden and Self-Reported Frequency of Depressive/Anxious Feelings in Older Adults.

Using the 2018-2021 National Health Interview Survey data, we examined the associations between healthcare cost burden and depressive/anxious feelings in older adults. Nearly12% reported healthcare cost burden and 18% daily/weekly depressive/anxious feelings. Healthcare cost burden was higher among women, racial/ethnic minorities, those with chronic illnesses, mobility impairment, and those with Medicare Part D, but lower among individuals with Medicare-Medicaid dual eligibility, Medicare Advantage, VA/military insurance, and private insurance. Daily/weekly depressive/anxious feelings was higher among healthcare cost burden reporters. The COVID-19 pandemic-related medical care access problems were also associated with a higher risk of reporting healthcare cost burden and depression/anxiety.

Associations of Depression/Anxiety with Technology Use, Discontinued Use, and Nonuse in Older Adults.

OBJECTIVES: To examine correlates of the changes in technology use among older adults and the associations of depression/anxiety symptoms with technology use changes. METHODS: We used the 2019-2021 U.S. National Health and Aging Trends Study (N = 3,063; age 70+). We fitted multinomial logistic regression models to examine: (1) correlates of never use and discontinued use versus use of email/texting and the internet during the 3-year study period; and (2) associations of past-month depression/anxiety symptoms in 2021 with use and discontinued use versus never use of email/texting and social network site (SNS). RESULTS: The findings show age, socioeconomic, and health barriers to technology use. Email/texting and SNS use in 2021, compared to never use in all 3 years, was associated with a lower likelihood of moderate/severe depression/anxiety symptoms in 2021 (RRR = 0.54, 95% CI = 0.37-0.81 for email/texting use; RRR = 0.56, 95% CI = 0.33-0.97 for SNS use). Video calls with family/friends were not associated with depression/anxiety symptoms. CONCLUSIONS: The findings expand the existing knowledge base regarding potential impact of technology use on mental health beyond the early months of the COVID-19 pandemic. CLINICAL IMPLICATIONS: More concerted efforts are warranted to help older adults' technology uptake and continued use and to promote mental health benefits of technology use.

Mental Health Treatment Use, Perceived Treatment Need, and Reasons for Non-Use Among U.S. Adults with Serious Suicidal Thoughts During the COVID-19 Pandemic.

Analyzing the 2021 National Survey on Drug Use and Health data with generalized linear models, we examined: (1) COVID pandemic-related and other correlates of mental health treatment use and unmet perceived treatment need among U.S. adults who experienced serious suicidal thoughts (N = 3,177); and (2) correlates of self-reported reasons for not receiving treatment. We found that 61% used any mental health treatment, and 48% of users and 37% of nonusers reported perceived treatment need. Significant correlates of treatment use were demographic factors, insurance, major depressive disorder, and illicit drug use disorder. Significant correlates of perceived treatment need were age 18-34, some college education, and major depressive episode. Perceived negative effect of the COVID pandemic on mental health was a significant factor for both treatment use and perceived need. The most frequent reasons for not getting treatment were the cost of treatment or lack of insurance and stigma-related concerns.

Suicide from intimate partner and other relationship conflicts: demographic and clinical correlates'.

BACKGROUND: A significant portion of suicides are precipitated by interpersonal relationship problems. AIMS: To examine demographic and clinical correlates of any intimate partner conflicts (IPC) and other interpersonal conflicts (OPC) as suicide precipitants. METHODS: We analyzed data on 92,805 (72,628 male; 20,177 female) adult suicide decedents from the 2017 to 2019 U.S. National Violent Death Reporting System, using multinomial and binary logistic regression models. We included case examples from coroners/medical examiner (CME) and law enforcement (LE) agency reports. RESULTS: Of all decedents, 23.6% had IPC and 8.0% had OPC as a suicide precipitant. Compared to those without any relationship conflict, those who had IPC or OPC were younger and more likely to have had previous suicide attempt(s), alcohol/other substance use problems, and job/finance/housing and legal problems. Compared to those with OPC, those with IPC were more likely to be male and Hispanic and had higher odds of previous suicide attempt, depression diagnosis, alcohol problems, and more acute crises. CME/LE reports showed distress of divorce/break-up, other life stressors, prior suicide attempt(s), alcohol/other substance involvement, and/or loss of family support. CONCLUSIONS: Access to behavioral health treatment for those at risk of suicide in the face of IPC or OPC is essential for suicide prevention.

Firearm use risk factors and access restriction among suicide decedents age 75 and older who disclosed their suicidal intent.

Background and aims: A majority of older adult suicide decedents used firearms. In this study, we focused on suicide decedents age 75+ who disclosed their suicidal intent within a month of their injury/death to examine demographic and clinical characteristics associated with firearm use and firearm access restriction attempts by their family members. Methods: The 2017-2019 U.S. National Violent Death Reporting System provided data (N = 1,734 suicidal intent disclosers; 1,476 males and 258 females; 21.4% of decedents age 75+). Generalized linear model (GLM) for a Poisson distribution with a log link was used to examine firearm use risk factors. Firearm access restriction attempts by decedents' family members were examined based on coroner/medical examiner and law enforcement (CME/LE) reports. Results: Nearly three quarters of disclosers disclosed their intent to family members, and 82.9% of males and 27.5% of females used firearms. GLM results showed males, non-Hispanic white people, and residents in the South and West regions had higher likelihood of firearm use. CME/LE reports of 140 out of 1,294 firearm decedents included narratives related to firearm restriction attempts or lack thereof. Firearm access restrictions were not attempted in 65 cases because family members did not take suicidal intent disclosure seriously or because decedents promised no self-harm. Partial or complete removal of firearms in 75 cases were not effective as decedents had hidden a firearm or purchased a new one. Others used different lethal methods. Implications: The findings indicate a need for: (a) training family members of older adults who are at risk of suicide in effective means safety/access restriction and strategies to prevent means substitution; (b) more comprehensive legislative reforms reducing access to firearms by those at risk of suicide; and (c) more comfort and palliative care and counseling for psychosocial risk factors.

Cocaine-involved suspected suicide attempts in individuals age 50 and older reported to United States Poison Centers.

CONTEXT: Despite a rapidly growing number of older cocaine users, the link between cocaine use and suicide attempt in older adults has not been examined. We examined associations between co-used other substances and (1) suspected suicide attempts versus other intentional misuse, and (2) major medical outcomes (major effect or death) of suspected suicide attempts and other intentional misuse. METHODS: We used the 2015-2021 United States National Poison Data System (N = 5,191 cases age 50 and older). Descriptive statistics and generalized linear models for a Poisson distribution with a log link function were used to examine the study questions. RESULTS: Cocaine exposures steadily increased from 2015 through 2021. Over the seven years, 52.3% and 47.7% were suicide attempts and other intentional misuse cases, respectively. Co-use of alcohol (incidence rate ratios = 1.24, 95% confidence interval = 1.14-1.35) and psychotropic (e.g., antidepressants: incidence rate ratios = 1.37, 95% confidence interval = 1.24-1.53) and cardiovascular medications were associated with a higher likelihood of suicide attempt, but co-use of prescription opioids, heroin, or other illicit drugs was associated with a lower likelihood of suicide attempt compared to other intentional misuse. Prescription opioids and amfetamine were associated with a higher likelihood of major effect or death in both suicide attempts and intentional misuse and heroin use and injection use were associated with a higher likelihood of major effect/death among intentional misuse cases. CONCLUSIONS: These findings show that significant proportions of older cocaine users who attempted suicide also used psychotropic and cardiovascular medications. We suggest that healthcare providers screen for suicidal ideation among cocaine users, with special attention to an increased risk of suicide attempts among those who co-use cocaine with alcohol and psychotropic and other prescription medications.

Physical Health Problems as a Suicide Precipitant: Associations With Other Risk Factors and Suicide Methods in Three Age Groups of Older Decedents.

Background and Objectives: Physical health problems are a significant late-life suicide precipitant. This study's purpose was to examine differences in (i) other suicide precipitants and psychiatric/substance use problems, and (ii) suicide methods (firearms, hanging/suffocation, and poisoning) in 3 age groups (55-64, 65-74, and 75+) of older suicide decedents who had physical health problems as a suicide precipitant. Research Design and Methods: Data came from the 2017-2019 U.S. National Violent Death Reporting System (N = 34,912; 27,761 males [79.5%] and 7,151 females [20.5%]). Generalized linear models for a Poisson distribution with a log link were used to examine the study questions. Results: Physical health problems were a suicide precipitant for 25.8%, 41.9%, and 57.7% of the 55-64, 65-74, and 75+ age groups, respectively, and were associated with a higher likelihood of having had depressed mood (IRR = 1.38, 95% CI: 1.33-1.43) and other substance use problems (IRR = 1.22, 95% CI: 1.13-1.31). Interaction effects showed that when job/finance/housing problems, depressed mood, or any psychiatric disorders were co-present with physical health problems, the age group differences in the predicted rates of physical health problems were diminished. Physical health problems were also positively associated with firearm and poisoning use, but negatively associated with hanging/suffocation. Interaction effects indicated that the predicted rates of firearm and poisoning use significantly increased among those aged 55-64 with than without physical health problems. Discussion and Implications: In all 3 age groups of older suicide decedents, physical health problems were the predominant suicide precipitant, and those with physical health problems had elevated depressed mood. Assessment of suicide risk, affordable and accessible health, and mental health services, restriction of access to lethal suicide methods, and policy-based suicide prevention approaches for older adults with physical health problems are needed.

Substance use and medical outcomes in those age 50 and older involving cocaine and metamfetamine reported to United States poison centers.

CONTEXT: Cocaine and metamfetamine use and overdose deaths among United States adults have been increasing in recent years. We examined associations of medical outcomes with co-used opioids and other substances among cocaine, and metamfetamine exposures in people age ≥50 years (N = 9300) reported to the National Poison Data System, 2015-2021. METHODS: We first described increases in these exposures over time. We fitted generalized linear models for a Poisson distribution with a log link, one for cocaine exposures and the other for metamfetamine exposures, to examine associations of medical outcomes (major effects/death versus all others) with co-used other substances, controlling for exposure year and demographics. RESULTS: The number of exposures increased steadily during the seven years, but metamfetamine exposures increased more rapidly starting in 2018. One-fifth of cocaine and one-sixth of metamfetamine exposures suffered major effects/death. Co-use of prescription opioids (incident risk ratio = 2.00, 95% CI = 1.76-2.28 for cocaine; incident risk ratio = 1.62, 95% CI = 1.27-2.07 for metamfetamine), illicit fentanyl (incident risk ratio =1.88, 95% CI = 1.08-3.27 for cocaine; incident risk ratio = 2.05, 95% CI = 1.04-4.06 for metamfetamine), heroin (incident risk ratio =1.62, 95% CI = 1.37-1.90 for cocaine), or amfetamine (incident risk ratio =1.73, 95% CI = 1.28-2.33 for cocaine) was associated with a higher likelihood of major effects/death. DISCUSSION: Increases in the number of cocaine and metamfetamine exposures among older adults reported to poison centers are of concern, and so is the increased risk of major effects/death from polysubstance use, especially prescription and illicit opioids, among these illicit psychostimulant users. CONCLUSIONS: Healthcare provider screening of individuals at risk of cocaine and/or metamfetamine use and psychoeducation about the dangers of these substance use are needed.

Changes in Older Adults' Frequency of Going Outside between 2020 and 2021: Associations with Health Status and Environmental Factors.

OBJECTIVES: To examine the changes in the frequency of going outside among U.S. older adults between 2020 and 2021 (post-COVID vaccine) and correlates of those changes. METHODS: We used the 2019-2021 National Health and Aging Trend Study (NHATS) (N = 3,063, age 70+) and multinomial logistic regression to analyze associations of increased and decreased frequencies in going outside with physical, psychosocial, and cognitive health, environmental (COVID concerns and transportation) factors, and social media use as the independent variables. RESULTS: In 2021 compared to 2020, 13% and 16% of those age 70+ reported increased and decreased frequencies, respectively. Increased frequency was associated with social media use. Decreased frequency was associated with poor physical health, depression/anxiety, and perceived memory decline. COVID concerns and transportation problems, as well as female gender, age 90+, and being non-Hispanic Black, were also significant correlates of decreased frequency. CONCLUSIONS: Most U.S. adults age 70+ appear to have resumed their 2019 level of frequency of going outside in 2021 after the COVID vaccines became available; however, 16% reported decreased frequency of going outside in 2021 compared to 2020. CLINICAL IMPLICATIONS: Older adults with physical, mental, and cognitive health challenges need help to increase their frequency of going outside.

Recurrent Falls over Three Years among Older Adults Age 70+: Associations with Physical and Mental Health Status, Exercise, and Hospital Stay.

We used the 2019-2021 U.S. National Health and Aging Trend Study (N = 3,063, age 70+) and multinomial logistic regression and generalized linear models with Poisson and log link to identify correlates of (1) recurrent falls (2 + falls) over 3 years (2019-2021); and (2) any subsequent fall among those who had a fall in 2019. We also examined the associations between falls and hospitalization in 2021. Results show that those with recurrent falls had greater physical/functional and psychological health problems in 2019, while single fallers over the 3 years were not significantly different from those without a fall. Exercise was associated with a lower likelihood of a subsequent fall among those who fell in 2019. Both a single fall and recurrent falls over the 3 years were associated with a higher risk of hospitalization in 2021. Multifactorial fall preventions including exercise and depression/anxiety treatment are needed to mitigate recurrent fall risks.

Psychological Distress, Cannabis Use Frequency, and Cannabis Use Disorder Among US Adults in 2020.

Using 2020 National Survey on Drug Use and Health data (N = 27,170, age 18+), we examined associations of psychological distress with: (1) cannabis use frequency among all adults, and (2) cannabis use disorder (CUD) among cannabis users. Of all adults, 18.2% reported past-year cannabis use, 12.9% reported mild-moderate psychological distress, and 12.9% reported serious psychological distress. Greater proportions of cannabis users, especially those under age 35, reported psychological distress. Of cannabis users, 28.1% met DSM-5 CUD criteria. Multinomial logistic regression results showed that serious, compared to no, psychological distress was significantly associated with cannabis use at all frequency levels. Both mild-moderate and serious levels of distress were associated with similar elevated CUD risk (RRR = 1.57, 95% CI = 1.15-2.15 for mild-moderate distress; RRR = 1.58, 95% CI = 1.19-2.09 for serious distress) and 2-4 times higher risks of having moderate or severe, compared to mild, CUD and higher odds of having alcohol use disorder. The prevalence of CUD and other substance use/use disorder among cannabis users is concerning as are the significant associations of psychological distress with greater cannabis use frequency, CUD, and other substance use/use disorder. Younger adults especially may benefit from increased behavioral health services given their high prevalence of psychological distress, cannabis use, and CUD.

Suicidal intent disclosure among adult suicide decedents: Four age group comparisons.

Research on who does/does not disclose suicidal intent (SI) and related factors has important implications for suicide risk management. In this paper based on the 2017-2019 National Violent Death Reporting System, we compared four age groups (18-24, 25-44, 45-64, and 65+ years) of suicide decedents with respect to associations between SI disclosure and (1) suicide contributing/precipitating factors, and (2) suicide means. The results shows that those age 18-44 were more likely to disclose SI than those age> =45, especially among those with relationship problems. Physical health problems and death/suicide of family/friend increased the likelihood of SI disclosure in the 65+ age group.

Three leading suicide methods in the United States, 2017-2019: Associations with decedents' demographic and clinical characteristics.

Background and aims: The U.S. suicide data show that use of lethal methods, specifically firearms and hanging/suffocation, has been increasing among young and middle-aged adults of both sexes over the past decades. In this study, we examined demographic and clinical correlates of use of firearms, hanging/suffocation, and poisoning as suicide methods among suicide decedents age 18+. Methods: Data came from the 2017-2019 National Violent Death Reporting System (NVDRS; N = 94,454, age ≥ 18 at the time of suicide; 74,042 men and 20,412 women). We fit generalized linear models (GLMs) for a Poisson distribution with a log link to examine (1) changes in four suicide methods (firearms, hanging/suffocation, poisoning, and other) during the study period, controlling for sex and age group; and (2) correlates of firearms, hanging/suffocation, and poisoning use. Results: In all age groups, 55% of men and 30% of women used firearms; 28% of men and 29% of women hanging/suffocation; 9% of men and 32% of women poisoning, and 8% of men and 9% of women "other" methods. Men age < 45 had higher likelihood of firearm and/or hanging/suffocation use than those age 45-64. Women age<45 also had higher likelihood of hanging/suffocation than those age 45-64. Prior suicide attempt history was associated with higher likelihood of poisoning in both sexes and hanging/suffocation in men; mental disorders/SUD were associated with higher likelihood of hanging/suffocation and poisoning in both sexes; physical health problems were associated with higher likelihood poisoning in both sexes and firearm use in men; relationship problems were associated with higher likelihood of firearm use; legal problems and job/financial/housing problems were associated with higher likelihood of hanging/suffocation in both sexes; and more crises were associated with higher likelihood of firearm use in both sexes. Implications: The findings call for the following suicide prevention strategies: (1) restricted access to firearms; (2) improved access to mental health/substance use treatment; (3) improved long-term and palliative care services for those (mostly older adults) with physical health problems; (4) financial/housing support policies to mitigate economic hardship; and (5) more research to identify effective strategies to curtail the increasing use of firearm and hanging/suffocation among young and middle-aged adults.

Job loss, financial strain, and housing problems as suicide precipitants: Associations with other life stressors.

Previous research has shown that job loss, financial strain, and/or loss of housing (JFH) in midlife elevate suicide risk. In this study based on the 2017-2019 National Violent Death Reporting System, we examined other suicide precipitants and contributors of decedents whose suicide was in part precipitated by JFH and the circumstances under which they died. First, we examined all adult decedents (N = 94,454; 74,042 males [78.4%] and 20,412 females [21.6%]) and then focused on decedents age 45-64 (N = 34,208; 25,640 males [75%] and 8568 females [25.0%]). The 45-64 age group had the highest rate of JFH (22.0% for males and 15.1% for females) as a suicide precipitant. The results of generalized linear models for all adult suicide decedents of both sexes showed that the 45-64 age group (IRR = 2.02, 95% CI = 1.89-2.16), compared to 65+ age group, and relationship problems, mental disorders, and alcohol problems were associated with significantly higher risk of JFH-precipitated suicide. In male decedents age 45-64, JFH was positively associated with depressed mood (IRR = 1.95, 95% CI = 1.85-2.06), alcohol problems (IRR = 1.14, 95% CI = 1.07-1.21), and number of crises (IRR = 1.48, 95% CI = 1.43-1.53). In female decedents age 45-64, JFH was positively associated with relationship problems (IRR = 1.19, 95% CI = 1.05-1.35), legal problems (IRR = 1.27, 95% CI = 1.06-1.54), depressed mood (IRR = 1.78, 95% CI = 1.59-1.99), and number of crises (IRR = 1.58, 95% CI = 1.48-1.68). In both sexes, the risk of JFH was also positively associated with a college education. In female decedents, JFH risk was higher among divorced or never-married individuals. Coroner/medical examiner and law enforcement agency reports show that some experienced depression and started misusing alcohol and/or other substances following a job loss, but others had these problems throughout life, which caused/contributed to JFH. These findings show the significance of suicide prevention approaches at both systemic (generous unemployment insurance, housing subsidies) and individual (treatment of depression and alcohol/substance misuse problems and social support/connection) levels.

Polypharmacy and Healthcare Service Use Among Prescription Opioid Poisoning Cases Age 50.

Objectives: To examine relationships between polypharmacy and level of healthcare service use among prescription opioid poisoning cases age 50 and older. Methods: Data came from the American Association of Poison Control Center's National Poison Data System, 2015-2020. We used multinomial logistic regression to examine the study questions. Results: Of the 77 946 cases with prescription opioid exposures, 64.5% were managed at a healthcare facility (HCF). Of HCF-managed cases, 41.2% were treated/evaluated and released and 21.3% and 37.5% were admitted for noncritical care and critical care, respectively. Medications for cardiovascular disease, benzodiazepines, other types of sedatives/hypnotics, antipsychotics, muscle relaxants, acetaminophen, and gabapentin were associated with increased risk of admission to both noncritical and critical care compared to treatment/evaluation and release. Acetaminophen use had the highest relative risk ratios (RRRs) for noncritical care (1.70, 95% CI = 1.51-1.91) and critical care (1.56, 95% CI = 1.39-1.76). Each additional medication/substance used was associated with 1.14 (95% CI = 1.11-1.17) and 1.19 (95% CI = 1.16-1.22) greater risk of noncritical and critical care admissions, respectively. Conclusions: Among older-adult poison control center cases for prescription opioid exposures, co-use of several commonly prescribed/used medicines was associated with increased risk of admissions to both noncritical and critical care units. Careful monitoring of medication use among older adults who use prescription opioids may reduce the risk of unintentional and intentional opioid poisoning.

Depression/anxiety symptoms and self-reported difficulty managing medication regimen among community-dwelling older adults.

OBJECTIVE: To examine the associations between depression/anxiety severity and changes in severity and self-reported difficulty managing medications among a representative sample of community-residing US Medicare beneficiaries without a reported dementia diagnosis. METHOD: We used the 2018 and 2019 National Health and Aging Trend Study (analysis sample N = 3198, 98% age 70+). Depression/anxiety was measured with the PHQ-4, and difficulty managing medication was self-reported. Following descriptive statistics, we fit a multinomial logistic regression model to examine the associations between depression/anxiety symptoms in 2018 and changes in severity between 2018 and 2019 and self-reported level of difficulty managing medication in 2019. RESULTS: Of past-month prescription medication users in 2019, 85.2%, 10.7%, and 4.1% reported no difficulty, a little/some difficulty, and a lot of difficulty or partial/full reliance on other's help for health/functioning reasons, respectively. Both mild and moderate/severe levels of depression/anxiety in 2018 were associated with significantly higher risks of a little/some difficulty and a lot of difficulty/other's help in 2019. Compared to no change in depression/anxiety symptoms between 2018 and 2019, decreased symptoms were associated with lower risk (RRR = 0.47, 95% CI = 0.28-0.78) and increased symptoms were associated with higher risk (RRR = 1.73, 95% CI = 1.12-2.67) of a little/some difficulty managing one's medication. CONCLUSIONS: Decrease and increase in depression/anxiety are associated with decreased and increased risk, respectively, of medication self-management difficulty among community-residing older adults. Healthcare providers should more carefully assess for medication management problems in their older adults with depression and anxiety symptoms and provide individually tailored interventions for those with great difficulty self-managing medication.

Associations of Healthcare Service Utilization With Cannabis Use Status, Use Reasons, and Use Characteristics Among Those Age 50 and Older.

Cannabis use has increased steadily among older adults, and they are a significant proportion of medical cannabis users. Using 2015-2019 National Survey on Drug Use and Health data (n = 44,007 age 50+), we examined whether the numbers of emergency department (ED) visits and nights hospitalized are associated with cannabis use status, use reason (nonmedical-only, medical-only, and medical and nonmedical), and use characteristics. Past-year users had higher rates of any ED visit (30.0%) and hospitalization (14.7%) than prior-to-past-year users and never users. However, negative binomial regression models showed that past-year users did not differ from never users on numbers of ED visits and nights hospitalized, although they had more ED visits than prior-to-past-year users (IRR = 1.21, 95% CI = 1.10-1.34). Medical-only users had more ED visits (IRR = 1.38, 95% CI = 1.02-1.88) than nonmedical-only users. Cannabis use and use characteristics were not associated with nights hospitalized. The study findings provide insights into older cannabis users' healthcare utilization.

U.S. older adults' heroin and psychostimulant use treatment admissions, 2012-2019: Sociodemographic and clinical characteristics.

BACKGROUND: Increases in U.S. older adults' nonprescription opioid and psychostimulant use call for examining their treatment admissions for these substances. METHODS: Using admissions age 55 + involving heroin (N = 299,073) from the 2012-2019 Treatment Episode Data Set-Admissions, we examined trends and sociodemographic and clinical characteristics of three groups: (1) heroin-only admissions (i.e., not involving cocaine or methamphetamine), (2) heroin-cocaine admissions, and (3) heroin-methamphetamine admissions. Bivariable and multivariable logistic regression analyses were conducted to examine the research questions. RESULTS: Between 2012 and 2019, the numbers of both heroin-only and heroin-cocaine admissions increased 2.3-fold and heroin-methamphetamine admissions increased seven-fold. First time heroin-methamphetamine admissions increased 18-fold. Heroin-methamphetamine admissions were concentrated in the Western region and heroin-cocaine admissions in the Northeastern region. Multivariable analyses showed a nearly 6 times higher relative risk ratio (RRR; 95% CI=5.24-6.74) for heroin-methamphetamine vs. heroin-only admissions in 2019 compared to 2012. Being non-Hispanic Black, compared to non-Hispanic White, was associated with a RRR of 2.4 (95% CI=2.34-2.46) for heroin-cocaine admissions and a RRR of 0.14 (95% CI=0.12-0.15) for heroin-methamphetamine admissions. Late-onset heroin use, experience of homelessness and other psychiatric problems, and past 30-day arrest episodes were associated with a higher likelihood of heroin-cocaine and heroin-methamphetamine admissions, while injection drug use (IDU) was associated with a higher likelihood of heroin-methamphetamine admissions only. CONCLUSIONS: Healthcare providers should assess and monitor psychostimulant, methamphetamine in particular, use among older adults. Those who use heroin and psychostimulants should receive substance use treatment and help to secure stable housing and meet other living needs.
