Influence of urban residence on use of psychotropic medications in Pennsylvania, USA: cross-sectional comparison of older adults attending senior centers

Trends, Patterns and Associated User Characteristics of Antidepressant Prescriptions in Older Adults: A Nationwide Descriptive Cohort Study in Denmark

BACKGROUND AND OBJECTIVE

Antidepressant use in older adults (≥ 65 years) is understudied in large population-based samples, particularly in recent years and regarding user characteristics. We aimed to describe the trends, patterns, and associated user characteristics of all antidepressant prescriptions redeemed by older adults at community pharmacies in Denmark during 2015-2019.

METHODS

This register-based study used a cross-sectional design to characterize antidepressant prescription trends and patterns, and a cohort design to describe user characteristics associated with antidepressant prescription initiation. We used descriptive statistics to characterize trends and patterns, and Poisson regression for analyzing user characteristics.

RESULTS

During the years 2015-2019, 17.9% of 1.2 million older adults redeemed 4.84 million antidepressant prescriptions, where 48.5% were selective serotonin reuptake inhibitors, followed by noradrenergic and specific serotonergic antidepressants (26.2%), serotonin-norepinephrine reuptake inhibitors (12.7%), tricyclic antidepressants (11.2%), and others (1.4%). Amitriptyline and nortriptyline, considered potentially inappropriate medications, were among the 10 most frequently redeemed antidepressants. Only 60.5% of prescriptions had a treatment indication of depression. Prescription-proportion trends by drug classes and individual antidepressants remained consistent. A higher incidence rate ratio (IRR) and 95% confidence interval (CI) of initiating antidepressants was associated with female sex (IRR 1.20, 95% CI 1.07-1.34), older age (e.g., 81-85 years vs. 65-70 years: IRR 1.74, 95% CI 1.44-2.11), living in rural areas (North Denmark vs. Capital Region: IRR 1.31, 95% CI 1.09-1.58), and having somatic and psychiatric diagnoses (e.g., per one psychiatric diagnosis: IRR 1.10, 95% CI 1.05-1.15), while a lower ratio was associated with being non-Western (vs. Danish: IRR 0.50, 95% CI 0.28-0.89) and having hospital contacts for psychiatric treatment (per each contact: IRR 0.96, 95% CI 0.93-1.00).

CONCLUSION

SSRIs were the most commonly redeemed antidepressants, with consistent trends in Danish older adults. Besides clinical conditions, sociodemographics, e.g., sex, age, ethnicity, and place of residence, may influence antidepressant use.

Psychotropic Use among Older Adults Living at Home: Use of the Anatomical Therapeutic Chemical (ATC) Drug Classification System and Beers Criteria®

The study examined medication use among older adults living at home and connection between background characteristics, urban/rural residency, and medication use according to Anatomical Therapeutic Chemical (ATC) drug classification system and Beers Criteria^®. Population-based cross-sectional study, participants (N = 175) were randomly selected from the Icelandic national registry, randomized by age, gender, and residence. On average, participants took 2.9 medications: 20% used psychotropics and 15% used psychotropics in ATC groups N05/N06A, which are deemed inappropriate for this age group according to Beers Criteria. Beers Criteria are useful for recognizing possible inappropriate medications for older adults and can be utilized by mental health nurses to assess the appropriateness of geriatric pharmaceutical treatments.

Psychoactive drug use and falls among community-dwelling Turkish older people

OBJECTIVE:

Data on the relationship between fall and psychoactive drug use among Turkish older people are limited. This study aims to investigate the prevalence of falls and the associations between psychoactive drug use and falls in community-dwelling Turkish older people.

METHODS:

This single center study was performed using the medical records of subjects aged over 65 years admitted to the geriatric care unit. Demographic and lifestyle factors, clinical characteristics, medications, and data on mood, cognitive status, and functional performance were obtained from the comprehensive geriatric assessment records. Based on a fall history in the last 12 months, subjects were grouped as fallers and non-fallers. Subjects treated with a psychoactive drug were identified.

RESULTS:

Among the total of 429 subjects, there were 184 (42.9%) fallers and 245 (57.1%) non-fallers. Of those, 33.3% were on psychoactive drug treatment. The proportion of psychoactive drug users was higher in the fallers group compared to non-fallers (45.1% vs. 24.5%, p<0.001). Multivariable logistic regression analysis showed age ≥75 years (OR=1.83;CI: 1.09–3.09; p=0.023), female gender (OR=2.70;CI: 1.6–4.50; p<0.001), and psychoactive drug use (OR=2.14;CI 1.32–3.48; p=0.002) as independent predictors of falls.

CONCLUSION:

We found that about one-third of geriatric outpatients were on psychoactive drug treatment in Turkey that was independently associated with the risk of falls.

Utilisation of emergency departments of behavioural disorders and supply of workforce in Nebraska

BACKGROUND

Emergency departments (EDs) have become entry points for treating behavioural health (BH) conditions, thereby rendering the evaluation of their utilisation necessary.

OBJECTIVES

This study estimated behavioural-related hospital-based ED visits and outcomes of leaving against medical advice as well as the incurred charges within the primarily rural State of Nebraska. Also, the study correlated behavioural workforce distribution and location of EDs with ED utilisation.

METHODS

Nebraska State Emergency Department Database provided information on utilisation of services, charges, diagnoses and demographic. Health Professional Tracking Services survey provided the distribution of EDs and BH workforce by region. To examine the effect of patient characteristics on discharge against medical advice, multivariable logistic regression modelling was used.

FINDINGS

US$96.4 million were ED charges for 52 035 visits for BH disorders over 3 years. Of these, 35% and 50% were between 25 and 44-years old and privately insured, respectively. The uninsured (OR:1.53, p=0.0047) and 45-64 years old (OR:2.31, p<0.001) had higher odds of leaving against medical advice. The findings from this study identified ED outcomes among high-risk cohort.

CONCLUSIONS

There were high ED rates among the limited number EDs facilities in rural Nebraska. Rural regions of Nebraska faced workforce shortages and had high numbers of ED visits at relatively few accessible EDs.

CLINICAL IMPLICATIONS

Customised rural-centric public health programmes, which are based in clinical settings, can encourage patients to adhere to ED-treatment. Also, increasing the availability of BH workforce (either via telehealth or part-time presence) in rural areas can alleviate the problem and reduce ED revisits.

Differences in Benzodiazepine Receptor Agonist Use in Rural and Urban Older Adults

BACKGROUND

Older adults are especially susceptible to adverse consequences of potentially inappropriate medications (PIMs), such as benzodiazepine receptor agonists (BZDRAs), due to age-related pharmacokinetic and pharmacodynamic changes. Although some risk factors for BZDRA use in older adults have been identified, the role of rural versus urban residence is less clear.

OBJECTIVE

To describe BZDRA use in rural versus urban older adults using pharmaceutical claims from Pennsylvania's Pharmaceutical Assistance Contract for the Elderly (PACE) program.

METHODS

The sample consisted of older adults enrolled in Pennsylvania's Healthy Steps for Older Adults and participated in Pennsylvania's PACE program. Independent sample t tests and contingency tables were used to examine residence differences. Multivariate binary logistic modeling was performed.

RESULTS

The total sample (N = 426) was 305 (71.6 %) urban-dwelling adults and 121 (28.4 %) rural-dwelling adults. Rural participants were more likely to be male, white, married, and have less than a high school education compared with urban participants (p <.01). Specifically, 25 % of rural-dwelling adults received a BZDRA compared with 15 % of urban-dwelling adults (p = 0.02). Three variables reached statistical significance for predicting BZDRA use in a multivariate model: rural residence (OR 2.58, 95 % CI 1.39-4.79), history of anxiety/depression (OR 4.20, 95 % CI 2.39-7.46), and number of medications (OR 1.11, 95 % CI 1.02-1.21).

CONCLUSIONS

BZDRA prescription differences in older, rural-dwelling adults further highlights the need for geriatric and mental health specialists to provide specialized care to this population. Rural healthcare professionals may be less aware of PIMs for older adults, and initiatives to support geriatric services and provide education for existing providers may be beneficial.
