Rate of Polypharmacy and Its Determinants Among Older Adult Cardiovascular Patients at Hiwot Fana Comprehensive Specialized Hospital in Eastern Ethiopia.

Understanding the rate of polypharmacy in cardiovascular patients is crucial because of its increasing occurrence and its association with potentially inappropriate prescribing practices and negative health outcomes, particularly among elderly individuals with cardiovascular conditions. According to the best of the literature search knowledge, the magnitude of polypharmacy and associated factors were not known among older cardiovascular patients in eastern Ethiopia. The aim of this study was to assess the rate of polypharmacy and its determinants among older adult cardiovascular patients at Hiwot Fana Comprehensive Specialized Hospital in eastern Ethiopia. A cross-sectional study design was undertaken, involving a cohort of 364 individuals aged 65 years and older who were receiving follow-up care for cardiovascular disease. A data abstraction sheet was used to gather the data. The convenience sampling technique was employed. To identify factors related to the rate of polypharmacy, multivariable logistic regression analysis was employed. The analysis included the medical records of 325 patients, revealing a polypharmacy prevalence rate of 20.7%. Individuals who were 77 years of age or older had a 1.12 times higher likelihood of having polypharmacy than individuals who were 65 to 70 years old. The presence of comorbidities along with cardiovascular diseases was a significant factor related to polypharmacy. Polypharmacy was prevalent among individuals with a larger number of comorbidities. This study reported that 1 in 5 cardiovascular patients at a chronic care clinic experienced polypharmacy. Age (≥77 years), having comorbidities, number of comorbid diseases (≥3), duration of cardiovascular disease (≥5 years), and number of years taking cardiovascular drugs (≥5) were associated with higher odds of polypharmacy. Health care providers should be cautious about prescribing multiple medications to this population. Training in the prevention of inappropriate polypharmacy is crucial to reducing the trend of polypharmacy and its associated burden.

Potentially Inappropriate Medications Use and Associated Factors Among Older Patients on Follow-Up at the Chronic Care Clinic of Hiwot Fana Comprehensive Specialized Hospital in Eastern Ethiopia.

Potentially inappropriate medications (PIMs) use often cause to poor health outcomes in older patients. There is a dearth of information on PIMS use in this population of patients seeking treatment at Hiwot Fana Comprehensive Specialized Hospital. To assess PIMs use and associated factors among older patients receiving follow-up treatment at the chronic care clinic of Hiwot Fana Comprehensive Specialized Hospital in eastern Ethiopia. A retrospective cross-sectional study using medical records of 419 older patients was conducted. older patients, aged 65 years or older, treated in the ambulatory care clinic were included. Simple random sampling technique was used. PIMs use was identified by using the 2023 American Geriatrics Society Beers Criteria (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) version 2 criteria. The multivariable logistic regression analysis was employed to identify factors associated with PIMs use. The strength of statistical association was measured by adjusted odds ratio (aOR) and 95% CI. P values < 0.05 were considered statistically significant. A total of 419 patients' medical records were reviewed. Of these, 411 patients' medical records fulfilled the inclusion criteria and were considered for final analysis. About 56.9% (n= 234) of the study population was women. The prevalence of PIMs use was 28.5% and 18.5%, according to 2023 AGS Beers Criteria and STOPP/START version 2 criteria, respectively. In accordance with 2023 AGS Beers Criteria, male sex (aOR = 1.78; 95% CI, 1.10-2.87), diabetes mellitus (aOR = 0.35; 95% CI, 0.19-0.62), and chronic kidney disease (aOR = 6.68; 95% CI, 2.55-9.32) were found to be the determining factors for PIMs use. According to STOPP/START version 2 criteria, deep vein thrombosis, diabetes mellitus, hypertension, and advanced age were the primary factors influencing PIMs use. Compared with other study findings from across the world, the prevalence of PIMs use was low. Based on 2023 AGS Beers Criteria, male sex, diabetes mellitus, and chronic kidney disease were found to be the determinant factors for PIMs use. Deep vein thrombosis, diabetes mellitus, hypertension, and advanced age were significant factor of PIMs use according STOPP/START version 2 criteria.

Medication Appropriateness, Polypharmacy, and Drug-Drug Interactions in Ambulatory Elderly Patients with Cardiovascular Diseases at Tikur Anbessa Specialized Hospital, Ethiopia.

Appropriate prescribing is often challenging in geriatric patients due to age-related pharmacokinetic and pharmacodynamic alterations. Elderly patients with cardiovascular diseases are frequently prescribed multiple medications. Hence, it is imperative to investigate medication appropriateness, polypharmacy, and drug-drug interactions in these groups of patients. To assess medication appropriateness using the 2019 American Geriatric Society Beers and Medication Appropriateness Index criteria, polypharmacy and drug-drug interactions among elderly ambulatory patients with cardiovascular diseases at Tikur Anbessa Specialized Hospital. A hospital-based retrospective cross-sectional study was conducted among 384 elderly (60 years and older) ambulatory patients with cardiovascular diseases between May 01-August 30, 2021. Data was collected from the patient's medical record using a data abstraction tool. The data were entered and analyzed using the SPSS program. Descriptive and logistic regression models were used to present the findings. The most frequent diagnosis was hypertension (78.4%) followed by ischemic heart disease (31.3%). Averagely, 4.4 ± 2 medications were prescribed per patient. More than half of (53.1%) the patients received polypharmacy. According to Beer's and medication appropriateness index criteria, over one-third (28.1%) and the majority (95.1%) of the patients were prescribed potentially inappropriate medications, respectively. In addition, 53.1% and 90.1% of patients had polypharmacy, and were exposed to potential drug-drug interactions ranging from mild to major interactions, respectively. Further, polypharmacy was significantly associated with inappropriate medication prescribing. The study found that more than half of the patients got one or more potentially inappropriate medications in both criteria. The medication appropriateness index tool identified more potentially inappropriate medication than the Beers criteria. In addition, more than half of the patients got polypharmacy and had potential drug-drug interactions. Further, polypharmacy was significantly associated with inappropriate medication prescriptions. These findings highlight the need for interventions to improve appropriate prescribing practice among elderly patients.
