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.

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.

Metabolic syndrome among type 2 diabetic patients in Ethiopia: a cross-sectional study.

BACKGROUND: Metabolic syndrome (MetS) increases risk of cardiovascular diseases (CVD), premature death as well as cost related to health care.This study was aimed at investigating the prevalence of MetS and its determinant factors among type2 diabetes mellitus (T2DM) patients attending a specialized hospital. METHODS: A cross-sectional study was conducted on a total of 256 T2DM patients from the first march to 30th May 2017 at university of gondar comprehensive specialized hospital (UGCSH). Data was collected based on STROBE (strengthening the reporting of observational studies in epidemiology) statement. Bivariable and multivariable logistic regression analysis were run to identify predictors of MetS from the independent variables and significance test was set at P <  0.05. RESULTS: The prevalence of MetS in this study was 70.3, 57 & 45.3% and it is more common in females (66.1, 83.3 & 70.7%) by using national cholesterol education program adult treatment panel III (NCEP-ATP III), International diabetic federation (IDF) and world health organization (WHO) criteria respectively. The most prevalent components of MetS were low level of high density lipoprotein (HDL) and triglyceride(TG). By usingIDF criteria, female gender was significantly associated with MetS (AOR = 0.2 at 95%CI: 0.1, 0.6 P = 0.00). Where as by NCEP-ATP IIIcriteria, age between 51 and 64 years old (AOR = 2.4 95% CI: 1.0,5.8, P = 0.04), self employment (AOR = 2.7 95% CI:1.1, 6.5, P = 0.03), and completetion of secondary school and above (AOR = 3.2, 95% CI:1.6,6.7, P = 0.001) were predictors for the development of MetS. In the WHO criteria, being single in marital status was significantly associated with MetS (AOR = 17 at 95%CI: 1.8, 166, P = 0.000). CONCLUSIONS: This study demonstrates that Metabolic syndrome is a major health concern for diabetic patients in Ethiopia and they are at increased risk of developing complications such as cardiovascular diseases and premature mortality. The predictors female gender, age between 51 and 64 years old, urban area residence, and being single are modifiable.Thus,health authorities shall provide targeted interventions such as life style modifications to these most at risk sub-populations of diabetic patients.

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.

Pattern and predictors of medicine use among households in Gondar Town, northwestern Ethiopia: a community-based medicine utilization study.

BACKGROUND: Medicine use can be influenced by several factors. Health managers need specific information about irrational use of medicines, in order to identify opportunities to enhance rational use of medicines in their communities. This study aimed to assess the pattern and factors associated with household medicine use in Gondar town, northwestern Ethiopia. METHODS: An interviewer-administered cross-sectional survey was conducted on 771 households, carried out between 5 April and 6 May 2015. The questionnaire contained items focusing on different aspects of medicine use in the households. The analysis involved descriptive summary and binary logistic regression test, which assessed association of independent variables with medicine use. RESULTS: Of the households interviewed, 22.4% (173/771) disclosed the presence of at least one chronic disease in the family; while 49.2% reported the use of medicine in the one month prior to the study. Almost all of the households (92.6%) reported a habit of discontinuing medicines, and 17.8% disclosed a practice of sharing medicines with household members and others. Level of education, presence of health professionals, and individuals with chronic illness in the households were linked to increased likelihood of reporting medicine use. Discarding leftover medicines with garbage (56.7%) was the principal means of disposal reported by the households. CONCLUSIONS: A high proportion of reported medicine use, together with problems such as sharing with other people and leaving medicines unfinished were found among the households in the study.

In vivo antiplasmodial activity evaluation of the leaves of Balanites rotundifolia (Van Tiegh.) Blatter (Balanitaceae) against Plasmodium berghei.

Balanites rotundifolia (BR) (Van Tiegh.) Blatter (Balanitaceae) has been used in Ethiopian folk medicine to treat malaria, despite the lack of scientific validation. Therefore, the present study was carried out to evaluate the antiplasmodial activity of 80% methanol leaf extract of BR in mice. Both the 4-day suppressive test and Rane's test were employed. Three extract doses (BR100 mg/kg, BR200 mg/kg, and BR400 mg/kg/d) were given orally, and chloroquine was the standard drug administered through the same route. Outcome measures for evaluating antiplasmodial efficacy were parasitemia level, packed cell volume, survival time, and body temperature as well as body weight change. Moreover, preliminary phytochemical and acute toxicity studies were carried out. With the 4-day suppressive test, BR demonstrated dose-dependent significant reduction in parasitemia level at all test doses compared to the negative control: BR400 (67%, P<0.001), BR200 (42%, P<0.01), and BR100 (37%, P<0.05). With Rane's test as well, BR significantly (P<0.001 for all test doses) reduced the parasitemia level by 38% (BR100), 45% (BR200), and 69% (BR400) in comparison to vehicle treatment. The crude extract was estimated to have oral median lethal dose higher than 2,000 mg/kg, and the presence of alkaloids and cardiac glycosides was confirmed. Therefore, this study for the first time validated the antiplasmodial activity of crude leaf extract of BR. Further investigations for isolating specific phytochemicals and elucidating mechanisms are needed to address the quest for novel antimalarial drugs.

A household survey of medicine storage practices in Gondar town, northwestern Ethiopia.

BACKGROUND: Household surveys are crucial to get accurate information on how medicines are acquired, and used by consumers, as they provide the best evidence in the area. The objective of this study was to document household medicine storage practices in Gondar town, northwestern Ethiopia. METHODS: A cross-sectional household survey was conducted from April 5 to May 6, 2015. In the study, 809 households were surveyed from four sub-cities in the town selected through multistage sampling with 771 included in the final analysis. Data on the extent of storage, storage conditions, sources of medicines and their current status among others were collected through structured interviews and observations. The data were entered in to Epidata version 3.1, exported to and analyzed using Statistical Packages for Social Sciences (SPSS) version 21. RESULTS: Of the 771 households in the study, 44.2% stored medicines. Presence of family members with chronic illness(es) and higher levels of household incomes predicted higher likelihood of medicine storage. In the households which allowed observation of stored medicines (n = 299), a mean of 1.85 [SD = 1.09] medicines per household were found. By category, anti-infectives for systemic use (23.9%), medicines for alimentary tract and metabolism (19.2%) and those for cardiovascular system (17.7%) ranked top. Among individual medicines stored, diclofenac (10.7%), paracetamol (9.9%) and amoxicillin (8.0%) were on top of the list. Dispensaries (97.8%) and physicians (83.5%) were almost exclusive sources of medicines and advices/orders for medicines respectively. Nearly two-thirds of the medicines found were on use and a vast majority (76.5%) were stored in chests of drawers. Proportion of expired medicines was very low (3.14%). CONCLUSIONS: The use of physicians' and pharmacists' advice to get medicines; use of dispensaries as principal sources, large proportion of medicines being in use and very low proportion of expiry showed good practices. However, storage places of medicines were not purpose built. Encouraging good practices through continued medicine use education and advocating appropriate medicine storage in medicine cabinets is required to improve storage conditions and consequent use of medicines.

Self-Medication Pattern among Social Science University Students in Northwest Ethiopia.

Background. Inappropriate self-medication causes wastage of resources among others. Method. This survey study was conducted to determine self-medication pattern of 404 social science university students in Northwest Ethiopia, who were selected through stratified random sampling technique. Data were collected using self-administered questionnaire and analyzed with SPSS version 20 statistical software. Binary Logistic Regression analysis was employed with P value < 0.05 considered statistically significant. Result. At 95.3% response rate, mean age of 21.26 ± 1.76 years, and male/female ratio of 1.26, the prevalence of self-medication during the six month recall period was 32.7%. Headache (N = 87, 69.1%) was the primary complaint that prompted the practice and hence analgesics (N = 67, 53.2%) were the mostly used drugs followed by antimicrobials (N = 50, 39.7%). The top two reasons driving the practice were nonseverity of the illness (N = 41, 32.5%) and suggestions from friends (N = 33, 26.2%). Female sex (P = 0.042) and higher income (P = 0.044) were associated with the practice. Conclusion. Self-medication practice, involving the use of both nonprescription and prescription drugs such as antimicrobials, among the social science university students is high. Therefore health education interventions regarding the risks of inappropriate self-medication are essential.

Evaluation of anti-ulcer activity of the leaf extract of Osyris quadripartita Decne. (Santalaceae) in rats.

Osyris quadripartita (OQ) Salzm. ex Decne. has been used to treat peptic ulcer disease in Ethiopian folk medicine, but its efficacy has not been validated. The present study was therefore carried out to evaluate the anti-ulcer activity of 80% methanol leaf extract of OQ in rats. The effect of OQ extract on gastric ulcer in rats in pylorus ligation-induced and ethanol-induced models was studied using single dosing (100, 200, 400 mg/kg) and repeated dosing (200 mg/kg for 10 and 20 days) approaches. Ranitidine (50 mg/kg) and sucralfate (100 mg/kg) were used as the standard drugs. Depending on the model, outcome measures were volume and pH of gastric fluid, total acidity, ulcer score, percent inhibition of ulcer score, ulcer index as well as percent inhibition of ulcer index. Data were analyzed using one-way analysis of variance followed by Tukey's post hoc test, and P<0.05 was considered as statistically significant. OQ significantly (P<0.001) reduced gastric ulcer index by 55.82% and 62.11%, respectively, in pylorus ligation-induced and ethanol-induced ulcer models at the 400 mg/kg dose, which is comparable to the standard drugs. Ten and 20 days pre-treatment with OQ200 exhibited significant (P<0.001) ulcer inhibition by 66.48% and 68.36% (pylorus ligation-induced model) as well as 71.48% and 85.35% (ethanol-induced model), respectively. OQ possesses both dose-dependent and time-dependent anti-ulcer effect in the two models. The oral median lethal dose (LD50) is estimated to be higher than 2000 mg/kg for the crude hydroalcoholic extract, and secondary metabolites such as flavonoids, tannins, and saponins were present. The findings of this study confirmed that OQ has anti-ulcer pharmacologic activity due to one or more of the secondary metabolites present in it. Therefore, this study validates its anti-ulcer use in Ethiopian folk medicine. Further investigations on isolation of specific phytochemicals and elucidating mechanisms of action are needed.
