Potentially inappropriate medication use among hypertensive older African-American adults

Polypharmacy, drug-drug interactions, and potentially inappropriate medications among older adults: a cross-sectional study in Northeast Ethiopia

Background

The global older adult population is expected to increase from 524 million in 2010 to 1.5 billion by 2050, mainly in developing countries. Age-related diseases, comorbidities, and polypharmacy make appropriate prescribing crucial. This study aimed to assess the prevalence of polypharmacy, drug-drug interaction, and potentially inappropriate medication use and its factors in an Ethiopian hospital.

Methods

A facility-based cross-sectional study on 236 patients aged 65 and above at Dessie Comprehensive Specialized Hospital (Jan 2022-Apr 2023) used the 2023 Beers Criteria and START/STOP V.3 to identify potentially inappropriate medications. Polypharmacy and potential drug-drug interactions were assessed using Micromedex®, with descriptive statistics and binary logistic regression performed in SPSS version 26.

Result

Of the 236 patients in this study, 94 (39.8, 95% CI: 35.7-44.5%) were prescribed at least one potentially inappropriate medication per the STOPP/START criteria, with 81 (34.3%) identified by STOPP and 13 (5.5%) by START. According to the Beers Criteria, 108 patients (45.7, 95% CI: 40.1-51.0%) received at least one potentially inappropriate medication. Polypharmacy was observed in 80 patients (33.9, 95% CI: 29.1-38.5%), and potential drug-drug interactions were identified in 111 patients (47.0%). Being female (AOR: 2.93), age ≥75 (AOR: 1.52), and polypharmacy (AOR: 3.20) were linked to potentially inappropriate medication use per Beers Criteria. Age 70-74 (AOR: 2.30) and polypharmacy (AOR: 3.10) were also associated per STOPP/START criteria.

Conclusion

Polypharmacy, drug-drug interactions, and potentially inappropriate medications are common among older Ethiopian patients, with age, sex, and polypharmacy as contributing factors. Future studies are needed to assess the health and economic impacts of potentially inappropriate medications use.

Potentially inappropriate medications for geriatric patients in Bahrain: prevalence, predictors, and implications for practice

BACKGROUND

The global increase in the older adult population necessitates a comprehensive understanding of medication management to mitigate the risks associated with potentially inappropriate medications (PIMs). These medications are of particular concern due to their association with adverse drug reactions, increased hospitalization, and increased healthcare costs. This study aimed to determine the prevalence and risk factors associated with PIM use among older adult patients attending primary health care centers in Bahrain.

METHODS

This cross-sectional study was conducted in 2022 in 27 primary healthcare centers across Bahrain. The study included patients aged 65 years or older. A computer based simple random sample was obtained, and the Beers criteria 2023 was utilized to assess medication appropriateness. Anonymous data was retrieved from electronic medical records and analyzed via univariate, and logistic regression analyses.

RESULTS

Among the 595 older adult patients studied, the average age was 71.7 years, with 54.5% (n = 324) being female. Most of the patients were married (70.8%, n = 421). More than half of the patients (51.3%, n = 305) received at least one PIM, with gliclazide (37%, n = 113), pantoprazole (29.8%, n = 91), and rabeprazole (27.9%, n = 85) being the most prevalent prescribed PIM. Univariate analyses revealed that PIM rates were significantly higher among females (p = 0.001) and patients with comorbidities such as diabetes mellitus (p < 0.001), essential hypertension (p < 0.001), and hyperlipidaemia (p < 0.001). Logistic regression analysis revealed that age (OR = 1.09, p < 0.001), female sex (OR = 1.645, p = 0.012), and diabetes mellitus (OR = 1.696, p = 0.029) were significant predictors of PIM use.

CONCLUSION

This study highlights the significant burden of PIM use among older adult patients in Bahrain, with more than half of the participants receiving at least one PIM. These findings underscore the urgent need for targeted interventions, particularly among female patients, those with chronic conditions such as diabetes mellitus, and patients taking five or more medications. These insights contribute to the broader understanding of geriatric pharmacotherapy and offer a foundation for policy development aimed at optimizing medication safety in aging populations.

Predisposing, enabling, and need factors influencing health-related quality of life among people with metabolic syndrome

BACKGROUND

Metabolic syndrome (MetS) continues to impact the health-related quality of life (HRQoL) of patients despite various available therapeutic interventions. There is a dearth of information on how patient-centered factors holistically predict HRQoL to provide more insights on addressing MetS.

OBJECTIVE

To predict the HRQoL of patients with MetS in the Southern states, using the predisposing, enabling, and need factors.

METHODS

The study adopted a cross-sectional approach in collecting 706 complete surveys on HRQoL assessment using the EQ-5D-5L survey and demographic characteristics based on the predisposing, enabling, and need factors of Andersen's Behavioral model. The study focused on people with MetS in the southern states of the United States. Multinomial logistic regression was conducted to investigate the relationship between the number of comorbidities and each HRQoL dimension. Ordinal regression was used to explore factors predicting HRQoL. Sensitivity analysis was conducted using bootstrapping analysis to evaluate the regression's robustness.

RESULTS

Over 70% were females and 30% had at least a bachelor's degree, while 47% were married. Most respondents (71.1%) had no problem with self-care. However, 20.0% had severe problems with pain, while the highest proportion (8.6%) was observed for extreme problems with anxiety or depression. A unit increase in comorbidities resulted in higher odds of having extreme problems with mobility (odds ratio [OR] = 1.95), usual activities (OR = 1.73), and pain (OR = 1.70). Only 40.8% of the respondents had good HRQoL, compared to 26.2% with poor HRQoL. Age, race, geographical area, marital status, household income, number of prescription drugs, comorbidities, and body mass index were predictors of HRQoL.

CONCLUSION

An increase in comorbidities significantly increased the odds of having challenges with the HRQoL dimensions. Demographic, socioeconomic, and health-related factors significantly predicted HRQoL. Therefore, health care providers must consider these factors as a component of patient-centered care to address health disparities and promote optimal health outcomes among people with MetS.

Potentially inappropriate prescribing among older adults with hypertension in China: prevalence and related comorbidities across different outpatient settings

Purpose

Potentially inappropriate prescribing (PIP) is commonly encountered in older adults; yet, there is limited information on the occurrence of PIP among older adults with hypertension. This study aims to determine and compare the prevalence of PIP and its association with comorbidities in older adult outpatients with hypertension across hospitals and community health centers (CHCs).

Methods

This 3-year (2015-2017) repeated cross-sectional study used electronic medical records from Shenzhen, China, involving 62 hospitals and 678 primary medical institutions. PIP was defined using the 2019 Beers Criteria. Older adults (≥65 years) with hypertension and at least one outpatient prescription were included. Modified Poisson regression analysis was used to assess the association between chronic comorbidities, healthcare settings, and PIP.

Results

The prevalence of PIP in old adult outpatients with hypertension in 2015, 2016, and 2017 was 46.32%, 46.98%, and 46.58% in hospitals, with a sample size of 38,411, 46,235, and 50,495, respectively, and 29.14%, 26.66%, and 29.84% in CHCs, with a sample size of 26,876, 29,434, and 34,775 respectively. The top four most popular PIP in hospitals and CHCs was proton-pump inhibitors (PPIs), diuretics, benzodiazepines, and non-cyclooxygenase-selective non-steroidal anti-inflammatory drugs (NSAIDs), respectively. PIP was most associated with chronic gastrointestinal disease (adjusted prevalence ratio = 1.54, 95% confidence interval [CI] = 1.50-1.59) and mental and behavioral disorders (adjusted prevalence ratio = 1.49, 95% CI = 1.46-1.53) in hospitals and with mental and behavioral disorders (adjusted prevalence ratio = 1.99; 95% CI = 1.95-2.03) and musculoskeletal system and connective tissue disorders (adjusted prevalence ratio = 1.33; 95% CI = 1.31-1.36) in CHCs. The prevalence of PIP was significantly higher in hospital settings than in CHCs (adjusted prevalence ratio = 1.65; 95% CI = 1.63-1.66).

Conclusion

Among older adult outpatients with hypertension in Shenzhen, PIP was more prevalent in hospitals than in CHCs. The comorbidities most strongly associated with PIP were chronic gastrointestinal disease and mental and behavioral disorders in hospitals and mental and behavioral disorders in CHCs. Clinical pharmacy integration needs to be considered to reduce inappropriate prescribing in this vulnerable population.

A mixed methods analysis of the medication review intervention centered around the use of the 'Systematic Tool to Reduce Inappropriate Prescribing' Assistant (STRIPA) in Swiss primary care practices

BACKGROUND

Electronic clinical decision support systems (eCDSS), such as the 'Systematic Tool to Reduce Inappropriate Prescribing' Assistant (STRIPA), have become promising tools for assisting general practitioners (GPs) with conducting medication reviews in older adults. Little is known about how GPs perceive eCDSS-assisted recommendations for pharmacotherapy optimization. The aim of this study was to explore the implementation of a medication review intervention centered around STRIPA in the 'Optimising PharmacoTherapy In the multimorbid elderly in primary CAre' (OPTICA) trial.

METHODS

We used an explanatory mixed methods design combining quantitative and qualitative data. First, quantitative data about the acceptance and implementation of eCDSS-generated recommendations from GPs (n = 21) and their patients (n = 160) in the OPTICA intervention group were collected. Then, semi-structured qualitative interviews were conducted with GPs from the OPTICA intervention group (n = 8), and interview data were analyzed through thematic analysis.

RESULTS

In quantitative findings, GPs reported averages of 13 min spent per patient preparing the eCDSS, 10 min performing medication reviews, and 5 min discussing prescribing recommendations with patients. On average, out of the mean generated 3.7 recommendations (SD=1.8). One recommendation to stop or start a medication was reported to be implemented per patient in the intervention group (SD=1.2). Overall, GPs found the STRIPA useful and acceptable. They particularly appreciated its ability to generate recommendations based on large amounts of patient information. During qualitative interviews, GPs reported the main reasons for limited implementation of STRIPA were related to problems with data sourcing (e.g., incomplete data imports), preparation of the eCDSS (e.g., time expenditure for updating and adapting information), its functionality (e.g., technical problems downloading PDF recommendation reports), and appropriateness of recommendations.

CONCLUSIONS

Qualitative findings help explain the relatively low implementation of recommendations demonstrated by quantitative findings, but also show GPs' overall acceptance of STRIPA. Our results provide crucial insights for adapting STRIPA to make it more suitable for regular use in future primary care settings (e.g., necessity to improve data imports).

Potentially Inappropriate Medication Use Among Older Patients with Diabetes in a Chinese Community

BACKGROUND

Potentially inappropriate medications (PIMs) are frequently prescribed to older people with diabetes. This study aimed to assess the prevalence of PIM use in older people with diabetes and identify potential risk factors influencing the development of PIM use.

METHODS

This was a cross-sectional study conducted in an outpatient setting in Beijing, China, using Chinese criteria. The prevalence of PIM use, polypharmacy, and comorbidities in older adults with diabetes in an outpatient setting was measured. Logistic models were employed to investigate the association among polypharmacy, comorbidities, and PIM use.

RESULTS

The prevalence of PIM use and polypharmacy was 50.1% and 70.8%, respectively. The most common comorbidities were hypertension (68.0%), hyperlipemia (56.6%), and stroke (36.3%), and the top three inappropriately used medications were insulin (22.0%), clopidogrel (11.9%), and eszopiclone (9.81%). Age (OR 1.025; 95% CI 1.009, 1.042), the number of diagnoses (OR 1.172; 95% CI 1.114, 1.232), coronary heart disease (OR 1.557; 95% CI 1.207, 2.009), and polypharmacy (OR 1.697; 95% CI 1.252, 2.301) were associated with PIM use.

CONCLUSIONS

Given the higher rate of PIM use among older adults with diabetes, strategies and interventions targeting this population are needed to minimize PIM use.

Potentially Inappropriate Medication Use among Underserved Older Latino Adults

BACKGROUND

Previous studies identified alarming increases in medication use, polypharmacy, and the use of potentially inappropriate medications (PIMs) among minority older adults with multimorbidity. However, PIM use among underserved older Latino adults is still largely unknown. The main objective of this study is to examine the prevalence of PIM use among underserved, community-dwelling older Latino adults. This study examines both the complexity of polypharmacy in this community and identifies associations between PIM and multimorbidity, polypharmacy, and access to medical care among this segment of our population.

METHODS

This community-based, cross-sectional study included 126 community-dwelling Latinos aged 65 years and older. The updated 2019 AGS Beers Criteria was used to identify participants using PIMs. We used multinomial logistic regression to examine the independent association of PIM with several independent variables including demographic characteristics, the number of chronic conditions, the number of prescription medications used, level of pain, and sleep difficulty. In addition, we present five cases in order to offer greater insight into PIM use among our sample.

RESULTS

One-third of participants had at least one use of PIM. Polypharmacy (≥5 medications) was observed in 55% of our sample. In addition, 46% took drugs to be used with caution (UWC). In total, 16% were taking between 9 and 24 medications, whereas 39% and 46% were taking 5 to 8 and 1 to 4 prescription medications, respectively. The multinomial logit regression analysis showed that (controlling for demographic variables) increased PIM use was associated with an increased number of prescription medications, number of chronic conditions, sleep difficulty, lack of access to primary care, financial strains, and poor self-rated health.

DISCUSSION

Both qualitative and quantitative analysis revealed recurrent themes in the missed identification of potential drug-related harm among underserved Latino older adults. Our data suggest that financial strain, lack of access to primary care, as well as an increased number of medications and co-morbidity are inter-connected. Lack of continuity of care often leads to fragmented care, putting vulnerable patients at risk of polypharmacy and drug-drug interactions as clinicians lack access to a current and complete list of medications patients are using at any given time. Therefore, improving access to health care and thereby continuity of care among older Latino adults with multimorbidity has the potential to reduce both polypharmacy and PIM use. Programs that increase access to regular care and continuity of care should be prioritized among multimorbid, undeserved, Latino older adults in an effort toward improved health equity.

Prevalence of Drug-Drug Interactions in Older Community-Dwelling Individuals: A Systematic Review and Meta-analysis

BACKGROUND

Drug-drug interactions (DDIs) can lead to medication-related harm, and the older population is at greatest risk. We conducted a systematic review and meta-analysis to estimate DDI prevalence and identify common DDIs in older community-dwelling adults.

METHODS

PubMed and EMBASE were searched for observational studies published between 01/01/2010 and 10/05/2021 reporting DDI prevalence in community-dwelling individuals aged ≥ 65 years. Nursing home and inpatient hospital studies were excluded. Study quality was assessed using the Joanna Briggs Institute critical appraisal tool. Meta-analysis was performed using a random-effects model with logit transformation. Heterogeneity was evaluated using Cochran's Q and I². DDI prevalence and 95% confidence intervals (CIs) are presented. All analyses were performed in R (version 4.1.2).

RESULTS

There were 5144 unique articles identified. Thirty-three studies involving 17,011,291 community-dwelling individuals aged ≥ 65 years met inclusion criteria. Thirty-one studies reported DDI prevalence at the study-participant level, estimates ranged from 0.8% to 90.6%. The pooled DDI prevalence was 28.8% (95% CI 19.3-40.7), with significant heterogeneity (p < 0.10; I² = 100%; tau² = 2.13) largely explained by the different DDI identification methods. Therefore, 26 studies were qualitatively synthesised and seven studies were eligible for separate meta-analyses. In a meta-analysis of three studies (N = 1122) using Micromedex^®, pooled DDI prevalence was 57.8% (95% CI 52.2-63.2; I² = 69.6%, p < 0.01). In a meta-analysis of two studies (N = 809,113) using Lexi-Interact^®, pooled DDI prevalence was 30.3% (95% CI 30.2-30.4; I² = 6.8%). In a meta-analysis of two studies (N = 947) using the 2015 American Geriatrics Society Beers criteria^®, pooled DDI prevalence was 16.6% (95% CI 5.6-40.2; I² = 97.5%, p < 0.01). Common DDIs frequently involved cardiovascular drugs, including ACE inhibitor-potassium-sparing diuretic; amiodarone-digoxin; and amiodarone-warfarin.

CONCLUSIONS

DDIs are prevalent among older community-dwelling individuals; however, the methodology used to estimate these events varies considerably. A standardised methodology is needed to allow meaningful measurement and comparison of DDI prevalence.

Prescribing Practices in Geriatric Patients with Cardiovascular Diseases

Inappropriate prescribing (IP) increases the risk of adverse medication reactions and hospitalizations in elderly patients. Therefore, it is crucial to evaluate prescribing patterns among this population. This study was designed to assess the prevalence of potentially inappropriate medication (PIMs) use and potential prescribing omissions (PPOs) among geriatrics with cardiovascular diseases (CVDs). In addition, it determined the predictors for IP in this population. A multi-center study was performed retrospectively on 605 patients' medical records collected randomly from seven governmental hospitals in Kuwait. Three of these hospitals have specialized cardiac centers (tertiary care). Inclusion criteria were age ≥ 65 years, diagnosed with at least one CVD, and attended the outpatient clinic during the last 6 months before data collection. A total of 383 patients (63.3%; 95% CI: 59.3-67.1%) were found using at least one PIM or having PPO or both, based on STOPP/START criteria. Three hundred and ninety-one patients (64.6%; 95% CI: 60.7-68.4%) were prescribed PIMs categorized as C and/or D medicines according to the Euro-FORTA list. Over one-quarter (28.8%; 95% CI: 25.2-32.6%) of the patients had drug-drug interactions class D that require therapy modification and/or X that should be avoided. Patients taking ≥ five medications had significantly higher PIMs based on STOPP and FORTA criteria, drug-drug interactions (p < 0.001), and significantly higher PPOs based on START criteria (p = 0.041). Patients with three or more chronic diseases had significantly higher PIMs based on STOPP and FORTA criteria and PPOs based on START criteria (p-values: 0.028, 0.035, and 0.005, respectively). Significantly higher PIMs based on STOPP criteria and PPOs based on START criteria were found in general hospitals compared to specialized cardiac centers (p= 0.002, p= 0.01, respectively). These findings highlight the need to develop and implement multifaceted interventions to prevent or minimize inappropriate prescribing among the geriatric population with CVDs in Kuwait.

Controversies in Hypertension II: The Optimal Target Blood Pressure

The optimal target blood pressure in the treatment of hypertension is undefined. Whether more intense therapy is better than standard, typically <140/90 mm Hg, is controversial. The most recent American guidelines recommend ≤130/80 mm Hg for essentially all adults. There have been at least 28 trials targeting more versus less intensive therapy, including 13 aimed at reducing cardiovascular events and mortality, 11 restricted to patients with chronic kidney disease, and 4 with surrogate endpoints. We review these trials in a narrative fashion due to significant heterogeneity in targets chosen, populations studied, and primary endpoints. Most were negative, although some showed significant benefit to more intense therapy. When determining the optimal pressure for an individual patient, additional factors should be considered, including age, frailty, polypharmacy, baseline blood pressure, and the diastolic blood pressure J-curve. We discuss these modifying factors in detail. Whereas the tenet "lower is better" is generally true, one size does not fit all, and blood pressure control must be individualized.

Polypharmacy and Health-Related Quality of Life/Psychological Distress Among Patients With Chronic Disease

Introduction

To date, no study has investigated the impact of polypharmacy (use of ≥5 medications concurrently) on health-related quality of life (HRQOL) and psychological distress in a combined sample of chronic disease patients and patients with multimorbidity, using diverse HRQOL measures. This study aimed to explore the association between polypharmacy and HRQOL/psychological distress by using data from a cross-sectional study in Flanders (Belgium).

Methods

We analyzed cross-sectional survey data on 544 chronically ill patients recruited from June 2019 through June 2021. HRQOL was measured with the EuroQol-5 Dimension-5 Level questionnaire (EQ-5D-5L) and the 12-Item Short Form Health Survey (SF-12); psychological distress was measured with the Hospital Anxiety and Depression Scale (HADS). Multiple linear regression models were built to assess the association between polypharmacy and HRQOL/psychological distress.

Results

Overall, compared with patients without polypharmacy, patients with polypharmacy reported worse EQ-5D-5L index values, EuroQol visual analogue scale (EQ-VAS) scores, SF-12 physical component scores (PCS), SF-12 mental component scores (MCS), and HADS anxiety and depression subscales. In the final regression model adjusting for age, sex, educational attainment, and multimorbidity, polypharmacy remained significantly associated with lower HRQOL in terms of the EQ-5D-5L index (β = −0.12; P = .008), EQ-VAS (β = −0.11; P = .01), and SF-12 PCS (β = −0.15; P = .002) but not with psychological distress (HADS) and SF-12 MCS.

Conclusion

This study found that polypharmacy was negatively associated with the physical domain of HRQOL, but not with the mental domain, among patients with chronic diseases. These results may be especially important for patients with multimorbidity, given their greater risk of polypharmacy.

Application of Prescription Reviews for Traditional Chinese Medicine to Improve Medical Disputes and Patient Satisfaction

Objective

Medical disputes and patient satisfaction are related to inappropriate prescribing practices. We aim to investigate the clinical application of prescription reviews for traditional Chinese medicine (TCM).

Method

TCM prescriptions performed prescription reviews in 372 patients from the year 2019 to 2020 were set as the observation group and those from the year 2017 to 2018 without prescription reviews as the control group (n = 341). According to the Criteria for Assessing Prescription Quality in Chinese Hospitals (CAPQCH) items, “Irrational” and “Rational” TCM prescriptions were determined mainly based on the following category: nonstandard prescriptions, inappropriate prescriptions, and hypernormal prescriptions. The incidence of medical disputes and the degree of patient satisfaction were compared between the two groups.

Result

No difference was found in age and gender between the control group and the observation group. The number of irrational TCM prescriptions from the year 2017 to 2020 was 6, 8, 2, and 3, respectively, with the percentage of 3.725%, 4.480%, 1.201%, and 1.446%. The irrational rate in the observation group (1.344%) was significantly lower than that in the control group (4.106%). Specifically, a higher rate of nonstandard prescriptions was revealed in the control group as compared with the observation group. Moreover, a reduced incidence of medical disputes was revealed in the observation group relative to the control group accompanying with the increased degree of patient satisfaction.

Conclusion

Prescription reviews have high application value in the management of Chinese pharmacies, which can improve the rationality of prescriptions, increase patient satisfaction, and reduce medical disputes.

Racial and ethnic disparities associated with the measure for drug-drug interactions among Medicare beneficiaries

BACKGROUND

Drug-drug interactions (DDIs) cause many preventable hospitalizations and admissions. Efforts have been made to raise DDI awareness and reduce DDI occurrence; for example, Medicare Part D Star Ratings, a health plan quality assessment program, included a DDI measure. Previous research reported racial and ethnic disparities in health services utilization and that racial and ethnic minorities, compared with non-Hispanic whites (whites), may be less likely to be targeted for a similar measure, a Star Ratings adherence measure for diabetes medications.

OBJECTIVE

This study aimed to investigate whether any racial and ethnic disparities are associated with the DDI measure in Part D Star Ratings among Medicare populations with diabetes, hypertension, and hyperlipidemia.

METHODS

This cross-sectional study analyzed a 2017 Medicare Part D data sample, including 3,960,813 beneficiaries. Because the inclusion in the denominator of the Star Ratings DDI measure was determined by the use of a list of target medications, the likelihood of using a listed target medication was compared between racial and ethnic minorities and whites. Individuals with diabetes, hypertension, and hyperlipidemia were included in the analysis owing to the high prevalence of these conditions. Patient- and community-level characteristics were adjusted by logistic regression.

RESULTS

Of the entire study sample, 26.2% used a target medication. Compared with whites, most racial and ethnic minorities were less likely to use a target medication. For example, among individuals with diabetes, blacks, Hispanics, Asians/Pacific Islanders, and others had, respectively, 14% (odds ratio 0.86 [95% CI 0.84-0.88]), 5% (0.95 [0.93-0.98]), 12% (0.88 [0.84-0.92]), and 10% (0.90 [0.87-0.93]) lower odds compared with whites. Findings were similar among hypertension and hyperlipidemia cohorts, except that Hispanics had similar odds of use as whites.

CONCLUSION

Most racial and ethnic minorities may have lower likelihood of being targeted for the DDI measure compared with whites. Future studies should examine whether these disparities affect health outcomes and devise new DDI measures for racial and ethnic minorities.

Potentially inappropriate medication prescribing among elderly patients with cardiovascular diseases

Background/Aim. The growing number of older adults means higher medicine utilization. The aim of the study was to determine the frequency and identify risk factors of potentially inappropriate medication (PIM) in the elderly population with cardiovascular diseases. Methods. The retrospective, cross-sectional study was performed in 2018, and the relevant data were collected during the period from January 2016 to December 2017. The study sample included 1,500 patients over 65 years with cardiovascular disease who had medical records at the Institute for Gerontology and Palliative Care, Belgrade. Assessment of PIM was done by standard international criteria such as the American Geriatrics Society 2015 updated Beers Criteria for PIM use in older adults. Results. PIM frequency in the elderly population was 70.3%. In relation to gender, it was more frequent in female elders. The mean number of prescribed drugs was similar for 2016 and 2017, 7.2 and 7.3, respectively. The most common were: medium-acting benzodiazepines (70.9%), central ? blockers (23.98%), and antipsychotics (typical and atypical) (20.94%). The most common comorbidity was noted in a group labeled with the International Disease Classification I00-I99, which includes heart and blood vessel diseases [n = 2,658 (36.9%)]. The most common diagnoses belonged to the subgroups I10-I15 [hypertensive diseases, n = 1,298 (18%)], I20-I25 [ischemic heart diseases n = 542 (7.5%)], I30-I52 [other forms of heart disease, n = 705 (9.8%)], I60-I69 [cerebrovascular diseases, n = 94 (1.3%)], and I80- I89 [diseases of veins, lymph vessels, and lymph nodes n = 12 (0.17%)]. The risk factors for PIM were: polypharmacy, gender, nicotine use, cognitive status, nutrition state, and the number of diseases registered in the study sample. Conclusion. Cardiovascular diseases in the elderly population are associated with a high prevalence of PIM. Creating health recommendations for prescribing drugs to the elderly that would emphasize these factors could reduce the prevalence of PIM in this population.

Potentially Inappropriate Medications Use among Older Adults with Comorbid Diabetes and Hypertension in an Ambulatory Care Setting

OBJECTIVE

This study aims to estimate the prevalence of PIMs use and its associated factors among older adults with comorbid diabetes and hypertension.

METHODS

A cross-sectional retrospective study was used, including 1,853 older adults (age ≥65 years) with diabetes and hypertension who visited an ambulatory care setting. The study objectives were to estimate the prevalence and factors associated with PIMs use based on the 2019 American Geriatric Society (AGS) Beers criteria.

RESULTS

Almost one out of two individuals had PIMs used, with the average number of medications taken being seven. The most commonly prescribed PIMs were the use of gastrointestinal and endocrine medications. High risk of PIMs use was among those with ischemic heart disease, anxiety, and polypharmacy.

CONCLUSIONS

Given the higher PIMs use among older adults with diabetes and hypertension comorbidities, tailored strategies and interventions to minimize PIMs use in this population are warranted.

Potentially inappropriate medication use among older adult patients on follow-up at the chronic care clinic of a specialized teaching hospital in Ethiopia. A cross-sectional study

Background

Older adult patients are prone to potentially inappropriate medication use (PIMU); its use has been associated with multiple adverse consequences. As a result, it is crucial to determine the magnitude and factors associated with PIMU. The present study was mainly aimed to determine and assess the magnitude and predictors of potentially inappropriate medication use in older adult patients on follow-up at the chronic care clinic of Jimma medical center.

Methods

A retrospective cross-sectional study was conducted involving 219 patients aged 65 years and above on treatment follow-up. Data was collected using a checklist. The 2019 updated American Geriatric Society (AGS) Beers Criteria® and Screening Tool of Older People’s Potentially Inappropriate Prescriptions criteria and Screening Tool to Alert Doctors to Right Treatment (STOPP/START) criteria (version 2) were employed to assess PIMU. SPSS IBM (v22) was used for data entry and analysis. Categorical variables were described using frequency and percentage, whereas continuous variables were described using mean with standard deviation (SD) or median with interquartile range (IQR). Logistic regression was conducted to identify predictors of PIMU.

Results

The average number of medications prescribed per patient was 4.0 (IQR = 2.0). At least one PIMU was identified in 182 (83.1%) and 99 (45.2%) patients, based on Beers and STOPP criteria, respectively. Additionally, potential prescription omission (PPO) was observed in 24 (10.9%) patients. The risk of Beers PIMU was increased with age [AOR = 1.21, p <  0.001], hypertension [AOR = 4.17, p <  0.001], and polypharmacy [AOR = 14.10, p <  0.001], while a decrease in the risk was noted in patients with a diagnosis of ischemic stroke [AOR = 0.133, p = 0.01] and asthma [AOR = 0.03, p <  0.001]. Using STOPP criteria, hypertension [AOR = 2.10, p = 0.04], diabetes mellitus [AOR = 2.26, p = 0.04], ischemic heart disease [AOR = 2.84, p = 0.04], peripheral neuropathy [AOR = 10.61, p <  0.001], and polypharmacy [AOR = 6.10, p <  0.001] significantly increased the risk of PIMU.

Conclusions

Regardless of the screening tool used to assess, the present study revealed PIMU in the large proportion of the participants. Multiple medication use and certain disease condition had increased the probability of PIMU. Hence, it is imperative to use screening tools for reviewing medications prescribed in older adult patients to ensure safety of medication therapy.

Polypharmacy and Potentially Inappropriate Medication Use in Older Blacks with Diabetes Mellitus Presenting to the Emergency Department

Background: Medication-related problems in older Blacks with diabetes mellitus (DM) are not well established. Objectives: To describe the frequency of medication-related problems in older Blacks with DM presenting to the emergency department (ED). Methods: The study was a cross-sectional analysis of baseline data from a randomized controlled trial evaluating Blacks aged ≥60 years of age presenting to the ED. Polypharmacy, potentially inappropriate medication (PIM) use, and anticholinergic score were evaluated. Results: Of 168 patients (median age = 68, range 60-92), most (n = 164, 98%) were taking ≥5 medications, and 67 (39.9%) were taking a PIM. A majority (n = 124, 74%) were taking a medication with an anticholinergic score ≥1. Number of medications was correlated with number of PIMs (r = .22, p = .004) and anticholinergic score (r = .50, p < .001). Conclusion: Polypharmacy and PIM use was common in older Blacks with DM.

Multi-Dimensional Impact of Chronic Low Back Pain among Underserved African American and Latino Older Adults

Chronic low back pain is one of the most common, poorly understood, and potentially disabling chronic pain conditions from which older adults suffer. The existing low back pain research has relied almost exclusively on White/Caucasian participant samples. This study examines the correlates of chronic low back pain among a sample of underserved urban African American and Latino older adults. Controlling for age, gender, race/ethnicity, education, living arrangement, and number of major chronic conditions, associations between low back pain and the following outcome variables are examined: (1) healthcare utilization, (2) health-related quality of life (HR-QoL) and self-rated quality of health; and (3) physical and mental health outcomes.

METHODS

We recruited nine hundred and five (905) African American and Latino older adults from the South Los Angeles community using convenience and snowball sampling. In addition to standard items that measure demographic variables, our survey included validated instruments to document HR-QoL health status, the Short-Form McGill Pain Questionnaire-2, Geriatric Depression Scale, sleep disorder, and healthcare access. Data analysis includes bivariate and 17 independent multivariate models.

RESULTS

Almost 55% and 48% of the Latino and African American older adults who participated in our study reported chronic low back pain. Our data revealed that having low back pain was associated with three categories of outcomes including: (1) a higher level of healthcare utilization measured by (i) physician visits, (ii) emergency department visits, (iii) number of Rx used, (iv) a higher level of medication complexity, (v) a lower level of adherence to medication regimens, and (vi) a lower level of satisfaction with medical care; (2) a lower level of HR-QoL and self-assessment of health measured by (i) physical health QoL, (ii) mental health QoL, and (iii) a lower level of self-rated health; and (3) worse physical and mental health outcomes measured by (i) a higher number of depressive symptoms, (ii) a higher level of pain, (iii) falls, (iv) sleep disorders, (v) and being overweight/obese.

DISCUSSION

Low back pain remains a public health concern and significantly impacts the quality of life, health care utilization, and health outcomes of underserved minority older adults. Multi-faceted and culturally sensitive interventional studies are needed to ensure the timely diagnosis and treatment of low back pain among underserved minority older adults. Many barriers and challenges that affect underserved African American and Latino older adults with low back pain simply cannot be addressed in over-crowded EDs. Our study contributes to and raises the awareness of healthcare providers and health policymakers on the necessity for prevention, early diagnosis, proper medical management, and rehabilitation policies to minimize the burdens associated with chronic low back pain among underserved older African American and Latino patients in an under-resourced community such as South Los Angeles.

Prevalence and impact of potentially inappropriate medication on community-dwelling older adults

INTRODUCTION

Potentially inappropriate medication is associated with adverse health and functional outcomes, as well as increased health care costs.

OBJECTIVE

To estimate the prevalence and types of potentially inappropriate medication according to the Beers criteria in community-dwelling older persons and to identify the major clinical and functional consequences of potentially inappropriate medication during two years of following.

MATERIALS AND METHODS

We conducted a longitudinal, descriptive, and observational study that included 400 65-year or older community-dwelling people (48% women) selected by simple random sampling in 2012. In 2014, 372 people were re-evaluated and classified into two groups based on the presence or absence of potentially inappropriate medication through the follow-up period.

RESULTS

In total, 31% had polypharmacy (5-9 medications) and 1,8% had excessive polypharmacy (10 or more medications). The mean of the number of medications was higher in the potentially inappropriate medication group (3 vs. 5.78; p<0.001) and 21.9% still had the potentially inappropriate medication status during the follow-up; of them, 75% had one potentially inappropriate medication and 23% two. The presence of potentially inappropriate medication was more frequent among frail and depressed male individuals with a bad health self-assessment and comorbidities, especially diabetes mellitus and chronic obstructive pulmonary disease. In the group with sustained potentially inappropriate medication, we found a worsening health self-assessment, increased frailty, a higher incidence of recurrent falls and prevalence of depression, as well as a higher hospital admission rate, ambulatory medical consultation, and more prescribed medications. We did not find an impact on functional capacity.

CONCLUSIONS

We validated the negative effects of potentially inappropriate medication in the long run for the health of older people and, therefore, potentially inappropriate medications should be monitored in primary care services to avoid greater risks.

Drug-Drug Interactions in Elderly Patients with Potentially Inappropriate Medications in Primary Care, Nursing Home and Hospital Settings: A Systematic Review and a Preliminary Study

Drug–drug interactions (DDI) occurring with potentially inappropriate medications (PIM) are additional risk factors that may increase the inappropriate character of PIM. The aim of this study was (1) to describe the prevalence and severity of DDI in patients with PIM and (2) to evaluate the DDI specifically regarding PIM. This systematic review is based on a search carried out on PubMed and Web-of-Science from inception to June 30, 2020. We extracted data of original studies that assessed the prevalence of both DDI and PIM in elderly patients in primary care, nursing home and hospital settings. Four hundred and forty unique studies were identified: 91 were included in the qualitative analysis and 66 were included in the quantitative analysis. The prevalence of PIM in primary care, nursing home and hospital were 19.1% (95% confidence intervals (CI): 15.1–23.0%), 29.7% (95% CI: 27.8–31.6%) and 44.6% (95% CI: 28.3–60.9%), respectively. Clinically significant severe risk-rated DDI averaged 28.9% (95% CI: 17.2–40.6), in a hospital setting; and were approximately 7-to-9 lower in primary care and nursing home, respectively. Surprisingly, only four of these studies investigated DDI involving specifically PIM. Hence, given the high prevalence of severe DDI in patients with PIM, further investigations should be carried out on DDI involving specifically PIM which may increase their inappropriate character, and the risk of adverse drug reactions.

Utilization and Spending on Potentially Inappropriate Medications by US Older Adults with Multiple Chronic Conditions using Multiple Medications

BACKGROUND

The utilization of potentially inappropriate medications (PIMs) in older adults can lead to adverse events and increased healthcare costs. Polypharmacy, the concurrent utilization of multiple medications, is common in older adults with multiple chronic conditions.

OBJECTIVE

To investigate the utilization and costs of PIMs in multimorbid older adults with polypharmacy over time.

METHODS

This retrospective cross-sectional study used linked Medicare claims and electronic health records from seven hospitals/medical centers in Massachusetts (2007-2014). Participants were ≥65 years old, had ≥2 chronic conditions (to define multimorbidity), and used drugs from ≥5 pharmaceutical classes for ≥90 days (to define polypharmacy). Chronic conditions were defined using the Chronic Conditions Indicator from the Agency for Health Research and Quality. PIMs were defined using the American Geriatrics Society 2019 version of the Beers criteria. We calculated the percentage of patients with ≥1 PIMs and the percentages of patients using different types of PIMs. We used logistic regression analyses to test the odds of taking ≥1 PIMs. We calculated mean costs spent on PIMs by dividing the costs spent on PIMs by the total medication cost.

RESULTS

≥69% of patients used ≥1 PIM. After adjusting for healthcare utilization, chronic conditions, medication intake, and demographic factors, female sex (2014: Odds ratio (OR)=1.27, 95%CI 1.25-1.30), age (2014: OR=0.92, 95%CI 0.90-0.93), and Hispanic ethnicity (2014: OR=1.41, 95%CI 1.27-1.56) were associated with PIM use. Gastrointestinal drugs and central nervous system drugs were the most commonly-used PIMs. In patients using ≥1 PIM, >10% of medication costs were spent on PIMs.

CONCLUSION

The utilization of PIMs in US older adults with multimorbidity and polypharmacy is high.

Factors associated with the use of potentially inappropriate medications by elderly people with hypertension

OBJECTIVE

to analyze factors associated with the use of potentially inappropriate medications by elderly people with hypertension.

METHOD

a cross-sectional study, conducted in the first semester of 2016, with elderly people undergoing treatment for hypertension, living in the city of Maringá. Interviews, medical records analysis, and measurement of clinical and anthropometric parameters of the participants were carried out. Inferential analysis was used.

RESULTS

a total of 260 elderly people who used potentially inappropriate medications participated in the study. The high use of these medications was associated with clinical and anthropometric conditions, such as obesity (p=0.022), smoking (p=0.004), polypharmacy (p=0.034) and the health services provided, such as organizationally accessible treatment (p=0.027) and consultation time (p=0.007), predisposing to low adherence to routine consultations (p=0.003).

CONCLUSION

it was shown that the factors associated with the use of potentially inappropriate medications were associated with anthropometric, clinical, and organizational variables, intrinsic to the family health strategy.

Medication interventions for African-American adults: Practice-based evidence from two nurse-led clinics

OBJECTIVE

This study was conducted to describe and examine the impact of medication intervention practices among African-American clients in two nurse-led community nursing centers (CNCs).

METHODS

This study used a retrospective-descriptive design. Omaha System data from visits of 196 African-American adults living with chronic disease and having two or more CNC visits in which medication regimen was an identified problem and the main reason for the visit was analyzed.

RESULTS

The sample had a mean age of 53.1 (6.67) and was primarily women (82%), uninsured, and with high school or less education. A total of 9,259 Medication regimen interventions were documented and implemented during 1,146 client CNC visits. A paired samples t test revealed statistically significant improvements in Knowledge (t = 2.434, p < .01). Behavior (t = 0.077, p = .94) and Status (t = 1.489, p = .14) remained unchanged, although the ratings trended toward improvement for each.

CONCLUSION

This study provides evidence that the nursing center model of care does improve the knowledge of medications among African-American clients. The study also demonstrated the Omaha System's utility to evaluate the impact of nursing interventions in community settings.

Community-dwelling older adults' awareness of the inappropriate use of proton pump inhibitors

Background

Proton pump inhibitors (PPIs) are effective in treating gastroesophageal reflux, peptic ulcers, and esophagitis. However, the long-term use of PPIs by older adults is associated with adverse health outcomes. There is limited evidence about older adults’ awareness of long-term PPI use and its associated adverse effects. This study aimed to assess older adults’ awareness of the adverse effects of the long-term use of PPIs, and their willingness to stop PPI use given of the risks and benefits of PPI use.

Methods

this cross-sectional study was conducted on a convenience sample of 120 older adults from three local healthcare centers located in Irbid, Jordan. Older adults’ awareness of PPI use was measured using the Patients’ Perceptions of Proton Pump Inhibitor Risks and Attempts at Discontinuation Survey.

Results

the majority of the participating older adults were not familiar with any reports linking long-term PPI use with adverse effects, reported no concerns related to the chronic use of PPIs, and reported that they had not discussed the benefits and risks of PPI use with their primary care providers (PCPs). Although the majority of the participants had not previously attempted to stop using PPIs, the majority expressed a willingness to stop PPIs due to their adverse effects, especially if advised to do so by a PCP. The factors associated with the long-term use of PPIs included age, indications for gastrointestinal reflux disease (GERD), improvement of GERD symptoms, and the willingness to reduce or stop PPIs. Being advised by a PCP to stop PPIs (p = 0.049) and having increased concerns about the adverse effects of long-term PPI use (p < 0.0001) were the only two statistically significant predictors of previous attempts to stop PPIs.

Conclusions

concerns regarding the adverse effects of long-term PPI use were associated with attempts to stop PPIs, especially in cases where this was recommended by a PCP. Discussions between PCPs and patients regarding the risks and benefits of PPIs are necessary in order to ensure that patients do not make inappropriate decisions regarding ongoing PPI therapy. Careful evaluation of the long-term use of PPIs among older adults is required.

Careful evaluation of the long-term use of PPIs among older adults is required.

Economic Strain Deteriorates While Education Fails to Protect Black Older Adults Against Depressive Symptoms, Pain, Self-rated Health, Chronic Disease, and Sick Days

Background

A large body of empirical evidence on Minorities' Diminished Returns (MDRs) suggests that educational attainment shows smaller health effects for Blacks compared to Whites. At the same time, economic strain may operate as a risk factor for a wide range of undesired mental and physical health outcomes in Black communities.

Aim

The current study investigated the combined effects of education and economic strain on the following five health outcomes in Black older adults in underserved areas of South Los Angeles: depressive symptoms, number of chronic diseases, pain intensity, self-rated health, and sick days.

Methods

This cross-sectional study included 619 Black older adults residing in South Los Angeles. Data on demographic factors (age and gender), socioeconomic characteristics, economic strain, health insurance, living arrangement, marital status, health behaviors, depressive symptoms, pain intensity, number of chronic diseases, sick days, and self-rated health were collected. Five linear regressions were used to analyze the data.

Results

Although high education was associated with less economic strain, it was the economic strain, not educational attainment, which was universally associated with depressive symptoms, pain intensity, self-rated health, chronic diseases, and sick days, independent of covariates. Similar patterns emerged for all health outcomes suggesting that the risk associated with economic strain and lack of health gain due to educational attainment are both robust and independent of type of health outcome.

Conclusion

In economically constrained urban environments, economic strain is a more salient social determinant of health of Black older adults than educational attainment. While education loses some of its protective effects, economic strain deteriorates health of Black population across domains. There is a need for bold economic and social policies that increase access of Black communities to cash at times of emergency. There is also a need to improve the education quality in the Black communities.

Depression Treatment Status of Economically Disadvantaged African American Older Adults

Background: It is known that depression remains largely untreated in underserved communities. Hence, it is desirable to gain more knowledge on the prevalence and correlates of untreated depression among African-American (AA) older adults in economically disadvantaged areas. This knowledge may have the public health benefit of improving detection of AA older adults with depression who are at high risk of not receiving treatment, thereby reducing this health disparity. Objective: To study health and social correlates of untreated depression among AA older adults in economically disadvantaged areas. Methods: Between 2015 and 2018, this cross-sectional survey was conducted in South Los Angeles. Overall, 740 AA older adults who were 55+ years old entered this study. Independent variables were age, gender, living arrangement, insurance type, educational attainment, financial strain, chronic medical conditions, and pain intensity. Untreated depression was the dependent variable. Logistic and polynomial regression models were used to analyze these data. Results: According to the polynomial regression model, factors such as number of chronic medical conditions and pain intensity were higher in individuals with depression, regardless of treatment status. As our binary logistic regression showed, age, education, and number of providers were predictive of receiving treatment for depression. Conclusion: Age, educational attainment, number of providers (as a proxy of access to and use of care) may be useful to detect AA older adults with depression who are at high risk of not receiving treatment. Future research may focus on decomposition of the role of individual-level characteristics and health system-level characteristics that operate as barriers and facilitators to AA older adults receiving treatment for depression.

Multimorbidity, polypharmacy and primary prevention in community-dwelling adults in Quebec: a cross-sectional study

BACKGROUND

Polypharmacy carries the risk of adverse events, especially in people with multimorbidity.

OBJECTIVE

To investigate the prevalence of polypharmacy in community-dwelling adults, the association of multimorbidity with polypharmacy and the use of medications for primary prevention.

METHODS

Cross-sectional analysis of the follow-up data from the Program of Research on the Evolution of a Cohort Investigating Health System Effects (PRECISE) in Quebec, Canada. Multimorbidity was defined as the presence of three or more chronic diseases and polypharmacy as self-reported concurrent use of five or more medications. Primary prevention was conceptualized as the use of statin or low-dose antiplatelets without a reported diagnostic of cardiovascular disease.

RESULTS

Mean age 56.7 ± 11.6, 62.5% female, 30.3% had multimorbidity, 31.9% had polypharmacy (n = 971). The most common drugs used were statins, renin-angiotensin system inhibitors and psychotropics. Compared to participants without any chronic disease, the adjusted odds ratios (ORs) for having polypharmacy were 2.78 [95% confidence interval (CI): 1.23-6.28] in those with one chronic disease, 8.88 (95% CI: 4.06-19.20) in those with two chronic diseases and 25.31 (95% CI: 11.77-54.41) in those with three or more chronic diseases, P < 0.001. In participants without history of cardiovascular diseases, 16.2% were using antiplatelets and 28.5% were using statins. Multimorbidity was associated with increased likelihood of using antiplatelets (adjusted OR: 2.98, 95% CI: 1.98-4.48, P < 0.001) and statins (adjusted OR: 3.76, 95% CI: 2.63-5.37, P < 0.001) for primary prevention.

CONCLUSION

There was a high prevalence of polypharmacy in community-dwelling adults in Quebec and a strong association with multimorbidity. The use of medications for primary prevention may contribute to polypharmacy and raise questions about safety.

Binge Drinking among Economically Disadvantaged African American Older Adults with Diabetes

Purpose. This study investigated the effect of demographic, socioeconomic, and psychological factors as well as the role of health determinants on alcohol consumption and binge drinking among economically disadvantaged African American older adults with type 2 diabetes mellites (T2DM). Methods. This survey recruited 231 African Americans who were older adults (age 65+ years) and had T2DM. Participants were selected from economically disadvantaged areas of South Los Angeles. A structured face-to-face interview was conducted to collect data on demographic factors, objective and subjective socioeconomic status (SES) including education and financial difficulty, living arrangement, marital status, health, and drinking behaviors (drinking and binge drinking). Results. Age, gender, living alone, pain, comorbid conditions, and smoking were associated with drinking/binge drinking. Male gender, pain, and being a smoker were associated with higher odds of drinking/binge drinking, while individuals with more comorbid medical conditions had lower odds of binge drinking. Conclusion. In economically constrained urban environments, gender, pain, and smoking but not age, SES, depression, and health may predict binge drinking for African American older adults with T2DM. African Americans older adult men with T2DM with comorbid pain should be screened for binge drinking.

Marijuana Use among African American Older Adults in Economically Challenged Areas of South Los Angeles

Purpose: This study explored demographic, social, behavioral, and health factors associated with current marijuana use (MU) among African American older adults who were residing in economically challenged areas of south Los Angeles. Methods: This community-based study recruited a consecutive sample of African American older adults (n = 340), age ≥ 55 years, residing in economically challenged areas of South Los Angeles. Interviews were conducted to collect data. Demographics (age and gender), socioeconomic status (educational attainment, income, and financial strain), marital status, living alone, health behaviors (alcohol drinking and cigarette smoking), health status (number of chronic medical conditions, body mass index, depression, and chronic pain), and current MU were collected. Logistic regression was used to analyze the data. Results: Thirty (9.1%) participants reported current MU. Age, educational attainment, chronic medical conditions, and obesity were negatively associated with current MU. Gender, income, financial strain, living alone, marital status, smoking cigarettes, drinking alcohol, depression, and pain did not correlate with MU. Conclusion: Current MU is more common in younger, healthier, less obese, less educated African American older adults. It does not seem that African American older adults use marijuana for the self-medication of chronic disease, pain, or depression. For African American older adults, MU also does not co-occur with cigarette smoking and alcohol drinking. These results may help clinicians who provide services for older African Americans in economically challenged urban areas.

Obesity and Polypharmacy among African American Older Adults: Gender as the Moderator and Multimorbidity as the Mediator

Despite high prevalence of obesity and polypharmacy among African American (AA) older adults, little information exists on the associations between the two in this population. This study explored the association between obesity and polypharmacy among AA older adults who were residing in poor urban areas of South Los Angeles. We also investigated role of gender as the moderator and multimorbidity as the mediator of this association. In a community-based study in South Los Angeles, 308 AA older adults (age ≥ 55 years) were entered into this study. From this number, 112 (36.4%) were AA men and 196 (63.6%) were AA women. Polypharmacy (taking 5+ medications) was the dependent variable, obesity was the independent variable, gender was the moderator, and multimorbidity (number of chronic medical conditions) was the mediator. Age, educational attainment, financial difficulty (difficulty paying bills, etc.), income, marital status, self-rated health (SRH), and depression were the covariates. Logistic regressions were used for data analyses. In the absence of multimorbidity in the model, obesity was associated with higher odds of polypharmacy in the pooled sample. This association was not significant when we controlled for multimorbidity, suggesting that multimorbidity mediates the obesity-polypharmacy link. We found significant association between obesity and polypharmacy in AA women not AA men, suggesting that gender moderates such association. AA older women with obesity are at a higher risk of polypharmacy, an association which is mainly due to multimorbidity. There is a need for screening for inappropriate polypharmacy in AA older women with obesity and associated multimorbidity.

Physician's Knowledge of Appropriate Prescribing for the Elderly-A Survey Among Family and Internal Medicine Physicians in Nigeria

Background: Prescription and use of inappropriate medications have been identified as a major cause of morbidity among the elderly. Several screening tools have been developed to identify inappropriate medications prescribed for elderly patients. There is dearth of information about the knowledge of Nigerian physicians regarding these screening tools and appropriate prescribing for the elderly in general. The primary objective of this study was to assess the knowledge of Nigerian physicians about these screening tools and appropriate prescribing of medications for the elderly.

Methods: The study was a cross-sectional questionnaire-based study conducted among physicians working in Family Medicine and Internal Medicine departments of four tertiary health care facilities in Nigeria. The questionnaire consisted of sections on general characteristics of respondents and their knowledge of four selected screening tools for inappropriate medications in the elderly. Ten clinical vignettes representing different therapeutic areas (using the best option type questions) about medicine use in the elderly were included with a score of 1 and 0 for correct and wrong answers, respectively. The knowledge of respondents was classified as (total score, over 10): poor (score, < 5), average (score, 5-6), and good (score, 7-10).

Results: One hundred and five physicians returned completed questionnaires. Twenty percent of respondents knew about Beers criteria, whereas 15.6% were familiar with the STOPP criteria. Majority (83; 84.7%) of the respondents were confident of their ability to prescribeappropriately for elderly patients. The mean knowledge score was 5.3 ± 2.0 with 32 (30.5%), 41 (39%), and 32 (30.5%) having low, average, and good scores, respectively. The association between the knowledge score, duration of practice, and seniority was statistically significant (OR, 3.6, p = .004 and OR, 3; p = .012), respectively.

Conclusion: There are significant gaps in the knowledge of Nigerian physicians about screening tools for inappropriate medications. There is a need for stakeholders involved in the care of elderly Nigerian patients to develop new strategies to improve services being offered. These may include introduction of modules on appropriate prescribing in the curriculum of undergraduate and postgraduate medical education and the routine use of some screening tools for inappropriate medications in daily clinical practice.

Substance Use among Economically Disadvantaged African American Older Adults; Objective and Subjective Socioeconomic Status

Purpose. This study investigated the effects of objective and subjective socioeconomic status (SES) indicators on two health behaviors, cigarette smoking and alcohol drinking, among African American older adults. Methods. This community-based study recruited 619 economically disadvantaged African American older adults (age ≥ 65 years) residing in South Los Angeles. Structured face-to-face interviews were conducted to collect data. Data on demographic factors (age and gender), subjective SES (financial difficulties), objective SES (educational attainment), living arrangement, marital status, healthcare access (insurance), and health (number of chronic medical conditions, self-rated health, sick days, depression, and chronic pain) and health behaviors (cigarette smoking and alcohol drinking) were collected from participants. Logistic regressions were used to analyze the data. Results. High financial difficulties were associated with higher odds of smoking cigarettes and drinking alcohol, independent of covariates. Educational attainment did not correlate with our outcomes. Similar patterns emerged for cigarette smoking and alcohol drinking. Conclusion. Subjective SES indicators such as financial difficulties may be more relevant than objective SES indicators such as educational attainment to health risk behaviors such as cigarette smoking and alcohol drinking among African American older adults in economically constrain urban environments. Smoking and drinking may serve as coping mechanisms with financial difficulty, especially among African American older adults. In line with the minorities' diminished returns (MDR) theory, and probably due to discrimination against racial minorities, educational attainment has a smaller protective effect among economically disadvantaged African American individuals against health risk behaviors.

Chronic Respiratory Disease and Health-Related Quality of Life of African American Older Adults in an Economically Disadvantaged Area of Los Angeles

Background. Most of the attention of policy makers, program planners, clinicians, and researchers in the area of physical health disparities among African American older adults has been traditionally focused on cardiometabolic disease and cancer. Among a long list of chronic medical conditions, chronic respiratory conditions (CRCs), such as asthma, chronic bronchitis, and emphysema, have received less attention. Purpose. This study investigated whether CRCs contribute to physical and mental health-related quality of life (HRQoL) of African American older adults who live in economically disadvantaged urban areas, and whether these effects are due to demographic factors, socioeconomic status (SES), health behaviors, and comorbid medical and mental conditions. Methods. This community-based study recruited 617 African American older adults (age ≥ 65 years) from Service Planning Areas (SPA) 6, an economically disadvantaged area in South Los Angeles. Structured face-to-face interviews were used to collect data on demographic factors (age and gender), SES (educational attainment and financial difficulty), living arrangements, marital status, health behaviors (cigarette smoking and alcohol drinking), health (CRC, number of comorbid medical conditions, depressive symptoms, and pain intensity), and physical and mental HRQoL (Physical and Mental Component Summary Scores; PCS and MCS; SF-12). Linear regressions were used to analyze the data. Results. The presence of CRCs was associated with lower PCS and MCS in bivariate analysis. The association between CRCs and PCS remained significant above and beyond all confounders. However, the association between CRCs and MCS disappeared after controlling for confounders. Conclusion. For African American older adults living in economically disadvantaged urban areas, CRCs contribute to poor physical HRQoL. Evaluation and treatment of CRCs in African American older adults may be a strategy for reduction of disparities in HRQoL in this population. As smoking is the major modifiable risk factor for CRCs, there is a need to increase accessibility of smoking cessation programs in economically disadvantaged urban areas. More research is needed on the types, management, and prognosis of CRCs such as asthma, chronic bronchitis, and emphysema in African American older adults who reside in low-income and resource limited urban areas.

Associations between Polypharmacy, Self-Rated Health, and Depression in African American Older Adults; Mediators and Moderators

Background. Despite the prevalence of multimorbidity among African American (AA) older adults, little information exists on correlates of polypharmacy (using 5+ medications) in AA older adults. There is more information available regarding the link between polypharmacy and physical aspects of health than subjective ones. Aims. In a local sample of AA older adults in Los Angeles, this study investigated the association of polypharmacy with self-rated health (SRH) and depression. We also explored gender differences in these links. Methods. This community-based study was conducted in south Los Angeles. A total number of 708 AA older adults (age ≥ 55 years) were entered into this study. From this number, 253 were AA men and 455 were AA women. Polypharmacy was the independent variable. Self-rated health (SRH) and depression were the dependent variables. Age, educational attainment, financial difficulty (difficulty paying bills, etc.), and marital status were covariates. Gender was the moderator. Multimorbidity, measured as the number of chronic diseases (CDs), was the mediator. Logistic regressions were applied for data analysis. Results. Polypharmacy was associated with worse SRH and depression. Multimorbidity fully mediated the association between polypharmacy and depressive symptoms. Multimorbidity only partially mediated the association between polypharmacy and poor SRH. Gender moderated the association between polypharmacy and SRH, as polypharmacy was associated with poor SRH in women but not men. Gender did not alter the association between polypharmacy and depression. Conclusions. AA older women with polypharmacy experience worse SRH and depression, an association which is partially due to the underlying multimorbidity. There is a need for preventing inappropriate polypharmacy in AA older adults, particularly when addressing poor SRH and depression in AA older women with multimorbidity.

Race/Ethnicity, Socioeconomic Status, and Polypharmacy among Older Americans

Background: Very few studies with nationally representative samples have investigated the combined effects of race/ethnicity and socioeconomic position (SEP) on polypharmacy (PP) among older Americans. For instance, we do not know if prevalence of PP differs between African Americans (AA) and white older adults, whether this difference is due to a racial gap in SEP, or whether racial and ethnic differences exist in the effects of SEP indicators on PP. Aims: We investigated joint effects of race/ethnicity and SEP on PP in a national household sample of American older adults. Methods: The first wave of the University of Michigan National Poll on Healthy Aging included a total of 906 older adults who were 65 years or older (80 AA and 826 white). Race/ethnicity, SEP (income, education attainment, marital status, and employment), age, gender, and PP (using 5+ medications) were measured. Logistic regression was applied for data analysis. Results: Race/ethnicity, age, marital status, and employment did not correlate with PP; however, female gender, low education attainment, and low income were associated with higher odds of PP among participants. Race/ethnicity interacted with low income on odds of PP, suggesting that low income might be more strongly associated with PP in AA than white older adults. Conclusions: While SEP indicators influence the risk of PP, such effects may not be identical across diverse racial and ethnic groups. That is, race/ethnicity and SEP have combined/interdependent rather than separate/independent effects on PP. Low-income AA older adults particularly need to be evaluated for PP. Given that race and SEP have intertwined effects on PP, racially and ethnically tailored interventions that address PP among low-income AA older adults may be superior to universal interventions and programs that ignore the specific needs of diverse populations. The results are preliminary and require replication in larger sample sizes, with PP measured directly without relying on individuals’ self-reports, and with joint data collected on chronic disease.

Cigarette Smoking among Economically Disadvantaged African-American Older Adults in South Los Angeles: Gender Differences

The current study aims to explore gender differences in the risk of cigarette smoking among African-American (AA) older adults who live in economically disadvantaged urban areas of southern Los Angeles. This cross-sectional study enrolled 576 older AA adults (age range between 65 and 96 years) who were residing in Service Planning Area 6 (SPA 6), one of the most economically challenged areas in southern Los Angeles. All participants had cardiometabolic disease (CMD). Data were collected using structured face-to-face interviews. Demographic factors (age and gender), socioeconomic status (educational attainment and financial difficulty), health (number of comorbid medical conditions and depressive symptoms), and health behaviors (current alcohol drinking and current smoking) were measured. Logistic regressions were used to analyze the data without and with interaction terms between gender and current drinking, depressive symptoms, and financial difficulty. AA men reported more smoking than AA women (25.3% versus 9.3%; p < 0.05). Drinking showed a stronger association with smoking for AA men than AA women. Depressive symptoms, however, showed stronger effects on smoking for AA women than AA men. Gender did not interact with financial difficulty with regard to current smoking. As AA older men and women differ in psychological and behavioral determinants of cigarette smoking, gender-specific smoking cessation interventions for AA older adults who live in economically deprived urban areas may be more successful than interventions and programs that do not consider gender differences in determinants of smoking. Gender-tailored smoking cessation programs that address drinking for AA men and depression for AA women may help reduce the burden of smoking in AA older adults in economically disadvantaged urban areas. Given the non-random sampling, there is a need for replication of these findings in future studies.

Polypharmacy in African American Adults: A National Epidemiological Study

Background: Despite the association between polypharmacy and undesired health outcomes being well established, very little is known about epidemiology of polypharmacy in the African American community. We are not aware of any nationally representative studies that have described the socioeconomic, behavioral, and health determinants of polypharmacy among African Americans. Aims: We aimed to investigate the socioeconomic and health correlates of polypharmacy in a national sample of African American adults in the US. Methods: The National Survey of American Life (NSAL, 2003⁻2004) included 3,570 African American adults. Gender, age, socioeconomic status (SES; education attainment, poverty index, and marital status), access to the healthcare system (health insurance and having a usual source of care), and health (self-rated health [SRH], chronic medical disease, and psychiatric disorders) in addition to polypharmacy (5 + medications) as well as hyper-polypharmacy (10 + medications) were measured. Logistic regressions were applied for statistical analysis. Results: that About 9% and 1% of all African American adults had polypharmacy and hyper-polypharmacy, respectively. Overall, higher age, higher SES (education and poverty index), and worse health (poor SRH, more chronic medical disease, and psychiatric disorders) were associated with polypharmacy and hyper-polypharmacy. Individuals with insurance and those with a routine place for healthcare also had higher odds of polypharmacy and hyper-polypharmacy. Conclusions: Given the health risks associated with polypharmacy, there is a need for systemic evaluation of medication use in older African Americans with multiple chronic conditions. Such policies may prevent medication errors and harmful drug interactions, however, they require effective strategies that are tailored to African Americans.

Polypharmacy and Psychological Distress May Be Associated in African American Adults

Background: Compared to Whites, African Americans are at a higher risk of multiple chronic conditions, which places them at a higher risk of polypharmacy. Few national studies, however, have tested whether polypharmacy is associated with psychological distress—the net of socioeconomic status, health status, and stress—in African Americans. Aims: In a national sample of African Americans in the US, this study investigated the association between polypharmacy and psychological distress. Methods: The National Survey of American Life (NSAL, 2003) included 3570 African American adults who were 18 years or over. This number was composed of 2299 women and 1271 men. Polypharmacy (using ≥ 5 medications) and hyper-polypharmacy (using ≥ 10 medications) were the independent variables. Psychological distress was the dependent variable. Age, gender, socioeconomic status (education attainment, income, employment, and marital status), health care access (insurance status and usual place of care), and health status (multimorbidity and psychiatric disorders) were the covariates. Linear multivariable regression was applied to perform the data analysis. Results: Both polypharmacy and hyper-polypharmacy were associated with psychological distress. This association was significant after controlling for all the covariates. Conclusions: African Americans with polypharmacy, particularly those with hyper-polypharmacy, are experiencing higher levels of psychological distress, which itself is a known risk factor for poor adherence to medications. There is a need for a comprehensive evaluation of medications as well as screening for psychopathology in African Americans with multiple medical conditions.

A Systematic Review of Studies of the STOPP/START 2015 and American Geriatric Society Beers 2015 Criteria in Patients ≥ 65 Years

BACKGROUND

Polypharmacy remains problematic for individuals ≥65.

OBJECTIVE

To summarise the percentages of patients meeting 2015 STOPP criteria for Potentially Inappropriate Prescriptions (PIPs), 2015 Beers criteria for Potentially Inappropriate Medications (PIMs), and START criteria Potential Prescribing Omissions (PPOs).

METHODS

Searches conducted on 2 January 2019 in Medline, Embase, and PubMed identified 562 studies and 62 studies were retained for review. Data were abstracted independently.

RESULTS

62 studies (n=1,854,698) included two RCTs and 60 non-randomised studies. For thirty STOPP/START studies (n=1,245,974) average percentages for ≥1 PIP weighted by study size were 42.8% for 1,242,010 community patients and 51.8% for 3,964 hospitalised patients. For nineteen Beers studies (n = 595,811) the average percentages for ≥1 PIM were 58% for 593,389 community patients and 55.5% for 2,422 hospitalised patients. For thirteen studies (n=12,913) assessing both STOPP/START and Beers criteria the average percentages for ≥1 STOPP PIP were 33.9% and Beers PIMs 46.8% for 8,238 community patients, and for ≥ 1 STOPP PIP were 42.4% and for ≥1 Beers PIM 60.5% for 4,675 hospitalised patients. Only ten studies assessed changes over time and eight found positive changes.

CONCLUSION

PIP/PIM/PPO rates are high in community and hospitalised patients in many countries. RCTs are needed for interventions to: reduce new/existing PIPs/PIMs/PPO prescriptions, reduce prescriptions causing adverse effects, and enable regulatory authorities to monitor and reduce inappropriate prescriptions in real time. Substantial differences between Beers and STOPP/START assessments need to be investigated whether they are due to the criteria, differential medication availability between countries, or data availability to assess the criteria.
