Drug-drug interactions among hospitalized elderly in patients at medical wards of Northwest Ethiopia's Comprehensive Specialized Hospitals: A multicenter observational study.

Objective: Drug-drug interactions are of major concern due to links to untoward drug effects, hospitalizations, and serious health impacts. Elderly patients are more predisposed to drug interactions than younger patients. The present study aimed to find out the prevalence of drug-drug interactions at North West Ethiopian compressive specialized hospitals' Internal Medicine wards. Methods: From 30 April to 30 July 2021 GC, a multicenter prospective observational study was conducted at north Ethiopian specialized hospitals. Data was collected by using a structured questionnaire adapted from different literature and medical records at the North West Ethiopian Comprehensive Specialized Hospitals' Internal Medicine wards during the study period. Thereafter checked the completeness of the collected data was checked drug-drug interactions by using Medscape. Epi data version 4.6.2 software was used as data clearance and STATA version 14.1 was used for further data analysis. Result: A total of 389 subjects participated in the study of which more than half (55.53%) of them were female with a mean (SD) age of 68.9 ± 7.46 years. A total of 641 drug-drug interactions were detected in this investigation of which, 225(35.1%) were major, 299(46.6%) were significant interactions, and 117(18.3%) were minor interactions. Hospital stay (AOR = 5.95 CI: 3.49-10.12), retire (AOR = 6.71 CI: 1.26-35.78), 5-9 drugs (AOR = 5.30 CI: 2.91-9.67) and more than 10 drugs (AOR = 8.03 CI: 2.47-26.07) were important risk factors for drug-drug interactions. Conclusion: The findings of this study suggest that drug-drug interactions were high among hospitalized elderly patients. The presence of polypharmacy, to be retired, and hospital stayed were all found to be strongly linked with drug-drug interactions.

Drug dose adjustment in patients with renal impairment attending a specialized referral hospital, Northwest Ethiopia.

Background: Numerous drugs and their metabolites are removed from the body through the kidney. Improper use of drugs in renal impaired patients may therefore, be harmful and have deleterious effects. Thus, this study was aimed at investigating drug dose adjustment in renal impaired patients attending a specialized hospital. Methods: A prospective cross-sectional study was performed at the medical ward in University of Gondar comprehensive specialized hospital from March to May 2018. During the study period, a total of 2100 patients were admitted to the general medical wards. We located and assessed 210 patient files, of which 189 patient files had complete notes. Based on our inclusion criteria, 105 patients had Crcl of ≥ 59 ml per min per 1.73 m2. Therefore, 84 patients fulfilled our inclusion criteria and were included in the final analysis. The collected data were entered into Epi Info version 7 and exported to the statistical package for the social sciences (SPSS) version 20 for statistical analysis. A chi-square test was applied to test the relationship between renal status and dosage adjustment. P-value ≤ 0.05 was considered as statistical significance. Since the number of co-morbidities and number of drugs prescribed was non-normally distributed using the Shapiro-Wilk test (P < 0.001), the spearman correlation test was used (r = 0.228, p = 0.037). Results: The mean age of study participants was 57 years with 57.1% male and 42.9% female. The highest number of renal impaired patients was in stage three 56(66.7%). The mean creatinine clearance (Crcl) was 41.8 ml/min (IQR 24.8-60.9), and the mean serum creatinine (Scr) value of 2.63 mg/dl (IQR 1.3-3.1). More than two third (76.2%) of the study participants had comorbidities. Eighty-four patients with 257 prescription entries were included in the study. Of which 75 prescription entries need a drug dose adjustment. The overall rate of inappropriate dose adjustment was 42.6% (32/75). Inappropriate dose adjustment was more common with vancomycin (14.3%) and ciprofloxacin (6%). Inappropriate drug dose adjustments were associated with patients having intermediate renal insufficiency (P < 0.002) and co-morbid conditions (P < 0.02). Conclusion: The present study demonstrated that inappropriate dose adjustment was common at University of Gondar comprehensive specialized hospital that needs great attention. Vancomycin and ciprofloxacin were the most frequently identified drugs that were inappropriately adjusted. Intermediate renal insufficiency and co-morbidities were statically significant with inappropriate dose adjustment.

Self-Reported Sedative Drug Use Among Students Attending at University of Gondar, Gondar, Northwest, Ethiopia: A Cross-Sectional Study.

BACKGROUND: Medical students experience significant psychological stress and are therefore at higher risk of using sedatives. There are currently no studies describing the prevalence of sedative drug use among medical students in Ethiopia. This study aimed to assess the prevalence and associated factors of self-reported sedative drug use among medical students attending the College of Medicine and Health Science (CMHS) students at the University of Gondar (UoG). MATERIAL AND METHODS: A prospective cross-sectional study was conducted from May to July 2018 in CMHS at UoG. Data were collected using a pre-tested self-administered standard questionnaire. Data were collected, entered into a computer using Epi Info 7 software, and analyzed using SPSS version 20. Frequency, mean, and standard deviation were used to describe descriptive statistics, and binary and multiple logistic regression analyses were used to assess the association between different variables and sedative drug use; P <0.05 was used to declare association. RESULTS: Of the 422 students who returned questionnaires, 26 (6.2%) participants were reported sedative drug use at some time since enrollment. Of these, 61.54% participants used antihistamine drugs. Smoking status (AOR (95% CI), 0.046 (0.009-0.241) P = 0.0001), stimulant use (AOR (95% CI), 0.220 (0.062-0.780) P = 0.019), sleeping hour (AOR (95% CI), 9.931 (4.155-14.785) P = 0.001) and sleep disorder (AOR (95% CI), 0.149 (0.033-0.680) P = 0.014) were significantly associated with sedative drug use. CONCLUSION: Self-reported sedative drug use among medical students at the University of Gondar is relatively low, and antihistamines are the most commonly used drugs. Smoking, stimulant use, sleeping hour, and the presence of sleep disorders were associated with sedative drug use.

Pharmacists' Knowledge and Practice of Issues Related to Using Psychotropic Medication in Elderly People in Ethiopia: A Prospective Cross-Sectional Study.

PURPOSE: This study is aimed at assessing pharmacists' knowledge and practice of issue related to usage of psychotropic medications in elderly people, in Gondar town Northwest, Ethiopia. METHODS: A cross-sectional study was conducted among pharmacists working in community, health center, and hospital pharmacies in Gondar town from March 1 to May 30, 2020. A total of 73 medication retail outlets (40 pharmacies and 33 drug stores) were included in this study. Pharmacy personnel's knowledge and practice were assessed using self-administered validated questionnaires. Binary and multivariable logistic regression analyses were used to assess the association between different variables. P < 0.05 was used to declare the association. RESULT: A total of 144 pharmacists were included in the study; the mean age was 30.13 (SD ±5.87), ranging from 20 to 55years. The mean knowledge score was 7.789 (SD ±2.98), and 75 (52.1%) of them had poor knowledge. The mean practice score was 2.32 ± 0.912 (mean ± SD), and 77 (53.5%) of the respondents had poor practice. All participants had not taken on-the-job training about psychotropic medication. Work experience (P < 0.029) and personal monthly income (P < 0.046) were significantly associated with pharmacists' knowledge. There was a significant association between work experience and practice level (P < 0.043). CONCLUSION: The knowledge and practice of pharmacy personnel were low for issues related to the use of psychotropic medication in the elderly. This result indicates the need for training for pharmacists on pharmacotherapy of psychotropic medication.

Factors Affecting Adherence to Co-Trimoxazole Preventive Therapy in HIV/AIDS Patients Attending an Antiretroviral Therapy Clinic in Ethiopia University Hospital: A Cross-Sectional Study.

PURPOSE: This study aimed to assess the factors that affect adherence to co-trimoxazole preventive therapy (CPT) among human immunodeficiency virus (HIV)-positive adults in an antiretroviral therapy (ART) clinic at the University of Gondar Compressive Specialized Teaching Hospital (UOGCSTH). METHODS: A hospital-based cross-sectional study was conducted from March 1 to April 30, 2018, at the ART clinic at UOGCSTH. Data were collected using face-to-face interviews with pretested and standard questionnaires. Binary and multivariable logistic regression analyses were used to assess the association between different variables. P<0.05 was used to declare the association. RESULTS: The prevalence of adherence to CPT by self-reporting measurement was 205 (67.8%). Factors such as level of education, taking street drugs (alcohol and khat), spouse knowledge about clients on CPT, knowledge of the benefit of CPT, duration of CPT, missed dose, got proper information on how to take CPT, and counseling done on refill were found to be significantly associated with adherence to CPT. CONCLUSION AND RECOMMENDATIONS: The overall adherence to CPT was fair in our study. To improve the adherence, continuous education and counseling, giving group service support for clients and having a separate counseling room are some of the possible solutions.

Prevalence and determinants of polypharmacy in cardiovascular patients attending outpatient clinic in Ethiopia University Hospital.

BACKGROUND: While there are advances in medicine and pharmaceutical care, the burden of medication use has also grown with polypharmacy. In this regard, cardiovascular patients are subjected to polypharmacy for a longer period. OBJECTIVE: The present study aimed to assess the prevalence and predictors of polypharmacy in cardiovascular outpatients attending the University of Gondar Comprehensive specialized hospital, northwest Ethiopia. METHODS: A hospital-based cross-sectional study was employed at the University of Gondar Comprehensive Specialized Hospital from March 30 -May 30, 2019. The unique medical registration number of 424 patients was selected by using systematic random sampling to trace the medical chart and followed with an interview to explore the factors related to polypharmacy. All the Statistical analysis was carried out using Statistical Package for Social Sciences (SPSS) version 22. Bivariable and multivariable logistic regressions were used to identify the predictors of polypharmacy in cardiovascular patients. RESULT: The mean age of the respondents was 56.83 ± 15.27 years. The mean number of medications per patient was 3.3±1.6. The prevalence of polypharmacy was 24.8% in cardiovascular outpatients while cardiovascular specific polypharmacy was 9.2%. Elderly (aged ≥ 65 years and above) patients were nearly two times more likely to had polypharmacy prescriptions with AOR: 1.97; 95% CI: 1.08-3.61; p = 0.027. Patients with abnormal weight (underweight AOR: 4.51; 95% CI: 1.42-14.30; p = 0.010, overweight AOR: 3.78; 95% CI: 1.83-7.83; p<0.001 and obese AOR: 5.1; 95% CI: 2.04-12.75 p<0.001) are more likely to have polypharmacy. Having a family history of CVD increase the likelihood of polypharmacy more than double; AOR: 2.40; 95% CI: 1.17-4.93; p = 0.017. A unit increase in Charlson comorbidity index score resulted in a nearly threefold likelihood of polypharmacy with AOR: 2.83; 95% CI 1.91-3.89; p<0.001. CONCLUSION: One out of four cardiovascular patients attending the outpatient clinic was on polypharmacy. The elderly age, abnormal body mass index (non-normal weight), family history of cardiovascular diseases and increasing Charlson morbidity index were the predictors of polypharmacy in cardiovascular patients. Clinicians should ensure the relevance of all prescribed medications and pharmaceutical care targeting at the prevention of inappropriate polypharmacy would be pivotal to reduce polypharmacy associated burdens.

Low Medication Knowledge and Adherence to Oral Chronic Medications among Patients Attending Community Pharmacies: A Cross-Sectional Study in a Low-Income Country.

OBJECTIVE: To investigate the level of knowledge, medication adherence, and the relationship among patients taking chronic oral medication and attending community pharmacies in Gondar, Northwest Ethiopia. METHODS: A cross-sectional study was conducted among adult chronic disease patients who were taking oral medications and getting service in 19 community pharmacies in Gondar City, Northwest Ethiopia. Patients' medication knowledge and adherence were assessed using interviewer-administered validated questionnaires. RESULTS: Of the 402 study participants (mean ± SD age = 44.7 ± 16.9 years, range = 18-86 years), 53.2% were males, 84.8% were aged <65 years, and 60.7% had high school education and above. About 348 (88.6%) respondents have used oral medications for more than one year. Less than half of respondents have good medication knowledge (n = 54, 38.3%) and were adherent to their medication (n = 158, 39.3%). Chronic disease patients with high school and above education are 5.35 times (95% CI: 3.231-8.857, p < 0.001) more likely to have good knowledge of their medication and having good medication knowledge was linked to higher medication adherence (AOR, 95% CI = 10.300 [6.16517.209]; p < 0.001). A statistically significant correlation was observed between the scores of medication knowledge and adherence (r = -0.471, p < 0.001). CONCLUSION: The majority of patients on oral chronic medications and attending community pharmacies in Gondar town do not have good medication knowledge and were nonadherent. Community pharmacists need to engage in medication counseling to improve medication knowledge and adherence of chronic disease patients.

Potentially inappropriate prescribing in Ethiopian geriatric patients hospitalized with cardiovascular disorders using START/STOPP criteria.

BACKGROUND: There was a paucity of data on the magnitude of potentially inappropriate prescriptions (PIPs) among Ethiopian elderly cardiovascular patients. OBJECTIVE: The aim of this study was to assess PIPs and associated factors in the elderly population with cardiovascular disorders using the START/STOPP screening criteria. METHODS: A hospital-based cross-sectional study was conducted at medical wards of a teaching hospital in Ethiopia from 1 December 2016-30 May 2017. Included patients were hospitalized elderly patients aged 65 years or older with cardiovascular disorders; their medications were evaluated using the START/STOPP screening criteria from admission to discharge. Multivariable logistic regression was applied to identify factors associated with inappropriate medications. One Way Analysis Of Variance (ANOVA) was carried out to test significant differences on the number of PIPs per individual diagnosis. RESULTS: Two hundred thirty-nine patients were included in the analysis. More-than a third of the patients were diagnosed with heart failure, 88 (36.82%). A total of 221 PIPs were identified in 147 patients, resulting in PIP prevalence of 61.5% in the elderly population. Of the total number of PIPs, occurrence of one, two and three PIPs accounted for 83 (56.4%), 52(35.4%), and 12(8.2%) respectively. One way ANOVA test showed significant differences on the mean number of PIPs per individual diagnosis (f = 5.718, p<0.001). Angiotensin Converting Enzyme Inhibitors (ACEIs) were the most common inappropriately prescribed medications, 32(14.5%). Hospital stay, AOR: 1.086 (1.016-1.160), number of medications at discharge, AOR: 1.924 (1.217-3.041) and the presence of co-morbidities, AOR: 3.127 (1.706-5.733) increased the likelihood of PIP. CONCLUSION: Approximately, two-thirds of elderly cardiovascular patients encountered potentially inappropriate prescriptions. ACEIs were the most commonly mis-prescribed medications. Longer hospital stay, presence of comorbidities and prescription of large number of medications at discharge have been correlated with the occurrence of inappropriate medication. It is essential to evaluate patients' medications during hospital stay using the STOPP and START tool to reduce PIPs.

Pharmacy students' provision of health promotion counseling services during a community pharmacy clerkship: a cross sectional study, Northwest Ethiopia.

BACKGROUND: Globally, undergraduate pharmacy education comprises practice programs aimed to address different competencies. This study was intended to investigate pharmacy students' provision of health promotion (HP) counseling services during a community pharmacy clerkship in Northwest Ethiopia. METHODS: A prospective cross-sectional study was conducted on fifty one fifth-year pharmacy students immediately after completion of a 2-week community pharmacy clerkship. Data were collected through a self-administered questionnaire. Relationship between variables was examined using Pearson's Chi-square test of independence, Mann-Whitney U test, and Spearman's rank correlation coefficient. RESULTS: The mean number of HP counseling service types delivered during the clerkship was 6.3 ± 2.8 out of 12. It is positively correlated with the number of HP counseling service types delivered in students' previous training (rho =0.437, p = 0.001). Nearly half (n = 25, 49%) of the students were actively-involved (i.e delivered ≥ 7 types of HP counseling service types) in the service and those who were well involved in previous training are more likely to do the same during the clerkship (X 2 = 4.581, p = 0.032). The main barriers perceived to hinder health promotion service were clients' lack of time and interest as well as absence of a guideline for health promotion service. CONCLUSION: Community pharmacy clerkship is a good opportunity for pharmacy students to develop health promotion counseling skill. Clerkship performance can best be improved through successful exposures to similar activities in previous courses and students shall be encouraged to carry out self-assessments of their health promotion counseling practice against standards set for the clerkship.

Involvement of community pharmacists in continuing professional development (CPD): a baseline survey in Gondar, Northwest Ethiopia.

BACKGROUND: Health care professionals have been striving to maintain their competence to deliver the best quality of service. This study intended to determine involvement in continuing professional development of community pharmacists in Gondar, Northwest Ethiopia. METHODS: About 46 community pharmacists, each from a different setting, were interviewed using structured questionnaire. Data were analyzed using Pearson's Chi-square test of independence and Mann-Whitney U test with p < 0.05 taken as statistically significant. RESULTS: The majority (n = 26, 56.5%) reported of being unaware of the CPD concept. The mean hour spent per week on CPD is 4.1 ± 4.0. Most (n = 34, 73.9%) were engaged in self directed learning and expressed an interest to be more involved in CPD activities (N = 39, 84.8%). Interactive workshops were the most preferred modality. However they seek further support in the process of identifying learning needs (N = 34, 73.9%). The main barriers for CPD engagement include lack of (N = 36, 78.3%) and inaccessibility (N = 34, 73.9%) of CPD opportunities as well as time shortage (N = 33, 71.7%). CONCLUSIONS: The community pharmacists in Gondar, Northwest Ethiopia lack awareness of CPD concept but engaged in various types of CPD activities. They demonstrated good attitude and seek more support. The main barrier was lack of opportunities related to CPD.
