Knowledge, attitude and practices regarding antimicrobial use and resistance among community members of Mtendere Township in Lusaka, Zambia: findings and implications on antimicrobial stewardship

Background: Antibiotic resistance is a public health problem affecting all countries and leads to an increase in morbidity and mortality rates. In Zambia, there is little information on the knowledge, attitude, and practices of community members about antibiotic use and resistance. This study assessed the knowledge, attitude and practices (KAP) regarding antimicrobial use (AMU) and antimicrobial resistance (AMR) among community members in Mtendere township of Lusaka Zambia. Methods: This was a cross-sectional study that was conducted from May 2020 to August 2020 using a structured questionnaire among 369 Mtendere residents. The data were analyzed using Statistical Package for Social Sciences (SPSS) version 22.0. Results: Of the 369 participants, 50.9% were male and 62.1% were aged between 18 and 29 years. Overall, this study found a poor KAP (38% good knowledge, 58% positive attitudes, and 52% good practices) regarding AMU and AMR. More than half of the participants 66.7% (246/369) had heard of antibiotics, 33.6% heard of AMR, and 23% heard of antimicrobial-resistant infections. Most of the participants 48.2% were not aware that AMR is a public health issue. A total of 52.8% (195/369) of the participants said they did not take antibiotics without consulting a doctor or pharmacist, translating into a prevalence of self-medication of 47.2%. Conclusions: This study showed that Mtendere residents had poor KAP towards antibiotic use and resistance. There is a need to implement community-based interventional campaigns including antimicrobial stewardship programmes address the gaps in KAP identified in this study

Assessment of knowledge, attitude and practices on antibiotic resistance among undergraduate medical students in the school of medicine at the University of Zambia

Background: The issue of antibiotic resistance has become a global public health concern, with an extensive clinical and economic burden. The study aimed to assess the knowledge, attitude, and practices of antibiotic resistance among undergraduate medical students at the University of Zambia.Methods: This cross-sectional study was conducted at the University of Zambia Ridgeway Campus. A structured questionnaire was administered to 260 randomly selected undergraduate medical students. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 22.0. Associations between dependent and independent variables were done using a Chi-square test. The statistical significance was done at 95% confidence level (p<0.05). Ethical approval was done by the University of Zambia Health Sciences Research Ethics Committee.Results: The study found that 227 of 260 (87.3%) of the medical students had good knowledge on antibiotic use and resistance. The majority of the medical students 252 of 260 (96.9%) had positive attitudes and 195 of 260 (75%) had good practices towards antibiotic resistance. There was a significant difference between the year of study and the level of knowledge (χ2=16.333, p=0.003). There was no significant difference between the year of study and the attitude of the participants (χ2=4.061, p=0.398). A significant difference was found between the year of study and the practices of the respondents (χ2=10.926, p=0.027).Conclusions: The medical students had good knowledge, a positive attitude, and good practices towards antibiotic resistance. Final year students had higher levels of knowledge and attitude but lower levels of practice compared to other years of study

Impact of COVID-19 on academic activities of final year nursing students: a Zambian reflection

Background: The novel coronavirus disease 2019 (COVID-19) has had many impacts on the education sector. The pandemic has had negative impacts on the academic activities of nursing students globally. Therefore, we assessed the impact of the COVID-19 on final year nursing students’ academic activities in Lusaka and Mufulira districts of Zambia.Methods: This was a cross-sectional study that employed quantitative methods using a structured questionnaire among 196 final year nursing students from 1August 2020 to 30 September 2020. Data were analysed using the statistical package for social sciences (SPSS) version 21.Results: A female predominance (67.9%) and a response rate of 86% were obtained. Many students strongly agreed (32.7%) and agreed (20.4%) that they did not complete their course work resulting in some concepts being poorly taught, 86.1% strongly agreed that they had delayed final examinations, and 51.5% strongly agreed that they did not do their clinical attachments. Students strongly disagreed (40.3%) that the e-library and wireless facilities in their school were well-stocked. Hence, this resulted in some students (40.3%) missing class lessons and assessments.Conclusions:The COVID-19 epidemic has negatively affected the academic activities of nursing students in Zambia. Ministries responsible for education must put in place measures that will mitigate the impact of COVID-19 on the education sector. Schools must adapt to the changes in the way of conducting learning and assessment sessions. Finally, schools must improve on their e-library and wireless facilities to effectively support online learning. 

World Health Organization AWaRe framework for antibiotic stewardship: Where are we now and where do we need to go? An expert viewpoint

The AWaRe classification categorizes antibiotics and is a tool for antimicrobial stewardship. To combat antimicrobial resistance, prescribers must adhere to the AWaRe framework, which promotes the rational use of antibiotics. Therefore, increasing political will, dedicating resources, building capacity, and improving awareness and sensitization campaigns may promote adherence to the framework

Knowledge, attitude, and practices on disposal methods of expired and unused medicines among students in public academic institutions in Lusaka, Zambia

Background: Unsafe disposal of unused and expired household medicines is a public health problem and mostly occur because of a lack of knowledge towards suitable medicine disposal methods. Thus, we aimed to assess the knowledge, attitude, and practices on the disposal methods of unused and expired medicines among students in public academic institutions in Lusaka, Zambia.Methods: This was a cross-sectional study in which 385 students from three higher learning academic institutions were interviewed face to face using a structured questionnaire from 10th May to 24th June 2019. The cleaned data was then transferred to statistical package for social science (SPSS) version 25.0 for analysis.Results: The mean age of the participants was 23 (SD±2.9). Out of the 385 participants, 215 (55.8%) did not know much about medical waste and 345 (89.6%) of them did not have any previous information regarding proper and safe disposal of unused and expired medicine. However, 351 (91.4%) of the participants appropriately responded that unsafe disposal of unused and expired medicine poses a threat to human health and can harm the environment. Throwing unused and expired medicine in household garbage/bin was the most frequently used disposal practice followed by flushing them in toilet/sink as responded by 231 (60.0%) and 128 (33.3%) of participants respectively. Only 17 (4.42%) reported returning unused and expired medicines to the nearest pharmacy.  Conclusions: The majority of the study participants used unsafe methods to dispose of unused and expired medicine. However, most of the participants acknowledged that unsafe disposal of unused and expired medicines is a public health problem and proposed the need to introduce drug take-back programs in the communities. 

Effects of medication knowledge on medication adherence among hypertensive patients at Matero level one hospital, Lusaka city, Zambia: a cross sectional study

Background: Medication adherence is the mainstay to good treatment outcomes. Failure to adhere to medication in hypertensive patients may lead to considerable deterioration of the disease resulting in increased costs of healthcare and mortality. Knowledge about the name of the drug, indications and side effects may enhance medication adherence. Therefore, the aim of this study was to assess effects of medication knowledge on medication adherence among hypertensive patients.Methods: This was a cross-sectional study that involved 120 hypertensive patients. A structured questionnaire was used to collect data on demographic characteristics. Adherence was assessed using the 8-item Morisky medication adherence scale while patient’s medication knowledge was assessed using a 7-item scale. Multiple logistic regression was used to assess factors associated with medication adherence.Results: The mean age of participants was 59 years (SD±14.9) and 10 (8.3%), 42 (35%) and 68 (56.7%) had adequate, average and poor medication knowledge respectively. The prevalence of adherence in this study was 37.5%. In multivariable logistic regression analysis, uncontrolled blood pressure (BP) (AOR: 0.38, CI: 0.16-0.90) was associated with lower likelihood of adhering to medication.Conclusions: The adherence level to treatment was low and medication knowledge of hypertensive patients was generally poor. Uncontrolled BP was associated with non-adherence. Patients with uncontrolled hypertension should be given health education and counselling regarding their condition to improve medication adherence.

Evaluation of pharmacological prophylaxis for deep venous thrombosis in hospitalized patients with risk factors at the university teaching hospitals, Lusaka, Zambia

Background: Deep venous thrombosis is a common clinical problem accounting for high rates of morbidity and mortality. The existence of risk factors, which include trauma, venous stasis, and hypercoagulability, is linked to the occurrence of the condition. Objective of current study was to evaluate DVT risk factors and prophylaxis pattern of use for patients who were admitted at the University Teaching Hospitals in Lusaka, Zambia.Methods: A cross-sectional study was conducted using medical files for patients who were hospitalized at the University Teaching Hospitals in Lusaka, Zambia from May 2020 to June 2021. Two hundred and ninety-six patient files were reviewed, and the Caprini risk assessment model was used to stratify patients into DVT risk categories. Multilinear regression analysis was used to identify factors associated with DVT prophylaxis.Results: Of the 296 patient files that were sampled from ICU, medical, and surgical wards, 198 (66.9%) (&gt;2 caprini score) were eligible for DVT prophylaxis, but only 77 (38.9%) of these eligible patients received prophylaxis. The number of eligible patients for DVT prophylaxis per department was as follows; ICU 50 (100%), Medical 71 (57.7%) and Surgery 77 (62.6%) wards. However, DVT prophylaxis was given to 21 (42%), 33 (46.5%), and 23 (29.9%) patients from the ICU, medical, and surgery, respectively. Enoxaparin was the most commonly used anticoagulant for Venous thromboembolism (VTE) prophylaxis with a mean dose of 60mg (SD±5). Across all departments, the most common predisposing risk factors for DVT were bed confinement for &gt;72 hours (167, 56.4%) and age of 41-60 years (118, 39.8%). In the adjusted model, swollen legs (AOR: 3.6, CI: 1.97, 6.57) and history of VTE (AOR: 21.3, CI: 9.87, 46.08) were significantly associated with a higher likelihood of DVT prophylaxis.Conclusions: Pharmacologic thromboprophylaxis is underutilized in patients in ICU, medical and surgical wards at the university teaching hospitals in Lusaka, Zambia. This study underscores the importance of implementing a DVT risk assessment technique for patients in ICU, medical and surgical wards and administering prophylaxis unless contraindicated

Antihyperglycemic and Antihyperlipidemic Effects of Aqueous Extracts of Lannea edulis in Alloxan-Induced Diabetic Rats

Lannea edulis (Sond.) Engl. commonly known as wild grape is used traditionally for the treatment of diabetes. It is only found in Eastern and Southern Africa. Phytochemical screening, antihyperglycemic and antihyperlipidemic effects of aqueous extracts of L. edulis in alloxan induced diabetic rats were carried out. We report herein the findings of this research work. Lannea edulis crude aqueous extracts were obtained by hot infusion and evaporation method. Phytochemical screening was carried out and subsequently toxicity studies of the aqueous extracts were performed to establish the Lethal Dose 50 (LD50) in albino rats. Alloxan monohydrate was used to induce diabetes in the rats. Lannea edulis positive control group doses of 100, 300, and 500 mg/kg were administered to 3 groups for 14 days. The positive control group was administered 5 mg/kg of glibenclamide. The negative and normal control groups were administered distilled water. To determine fasting blood glucose, blood was drawn on days 0, 1, 3, 5, 7, and 14 while it was drawn on days 0 and 14 for the determination of lipids. Phytochemical screening revealed the presence of flavonoids, saponins, tannins, cardiac glycosides, alkaloids and steroids. L. edulis diabetic positive control groups showed significant (P &lt; 0.05) dose dependent reductions in fasting blood glucose levels. When day 0 mean blood glucose levels were compared to day 3 mean blood glucose levels of their respective groups, the 300 mg/kg L. edulis group showed a 23.3% drop and the 500 mg/kg L. edulis group showed a 52.6% drop. The 100 mg/kg L. edulis diabetic positive control group showed a 25.1% drop by day 5, the day on which it showed statistical significance (P &lt; 0.05) compared to the diabetic control. In addition, administration of aqueous extracts of L. edulis to diabetic rats for 14 days significantly decreased (P &lt; 0.05) the levels of serum total cholesterol, triglycerides, Low Density Lipoprotein (LDL) and Very Low Density Lipoprotein (VLDL) whilst increasing the levels of High Density Lipoprotein (HDL), when compared to the diabetic control group. It was concluded that L. edulis showed significant and dose dependent antihyperglycemic and antihyperlipidemic effects thus confirming its traditional use

Knowledge, attitudes and practices on antimicrobial resistance among pharmacy personnel and nurses at a tertiary hospital in Ndola, Zambia: implications for antimicrobial stewardship programmes.

Introduction: Antimicrobial resistance (AMR) is a global public health problem that has led to increased morbidity and mortality, especially in low- and middle-income countries such as Zambia. This study evaluated AMR knowledge, attitudes and practices among pharmacy personnel and nurses at Ndola Teaching Hospital, Zambia's second-largest hospital. Methods: A descriptive cross-sectional study was conducted among 263 participants using a structured questionnaire. Data analysis was performed with IBM SPSS version 23.0. All statistical tests were conducted at a 95% confidence level. Univariate analysis was used to determine differences in knowledge, attitudes and practices on AMR between pharmacy personnel and nurses. Results: Of the 263 participants, 225 (85.6%) were nurses and 38 (14.4%) were pharmacy personnel. Compared with nurses, pharmacy personnel had better knowledge of the spread of resistant bacteria from one person to another (P = 0.001) and the use of antibiotics in livestock as a contributing factor to AMR (P = 0.01). Pharmacy personnel had better attitudes towards AMR as a public health problem (P = 0.001) and the use of antibiotics in livestock as a source of resistant pathogens (P = 001). Lastly, more pharmacy personnel than nurses participated in awareness campaigns (P = 0.029), continued professional development (P = 0.001) and courses on the use of antibiotics and AMR (P = 0.028). Conclusions: The study showed that most participants had adequate knowledge, a positive attitude and good practices towards AMR. Significant differences in knowledge, attitudes and practices were observed between pharmacy personnel and nurses in AMR, highlighting a need for increased educational programmes for these healthcare personnel

Medication omissions in the first 48 hours after admission: failure in prescribed medicines reaching in-patients in paediatrics wards at the University Teaching Hospitals, Children’s Hospital in Lusaka, Zambia

Background: The first few days of in-patient care are possibly the most significant in a patient’s recovery and any omitted medications during this period may harm the patient or increase their hospital length of stay. Therefore, our study aimed at assessing the frequency of medication administration omission errors and their reasons for the omission in the paediatric wards after admission at University Teaching Children’s Hospital.Methods: This was a descriptive study in which 259 patient files and drug charts were reviewed. Admission prescription charts were studied in detail over a period of four weeks and all drugs prescribed but then not given in the first 48 hours were recorded as omitted medications, along with the reason given for their omission.Results: From the 259 drug charts, a total of 1598 doses of drugs were ordered within 48 hours of admission. However, from this, only a total of 1132 doses were administered with the remaining 466 doses omitted, which accounted for a frequency of 29.2%. When the frequency of medication omission errors was compared, parenteral drugs (70.8% vs. 25.3%, [p=0.0001]), afternoon shift (48.5% vs. 15.8%, [p=0.0001]), and anti-infective medications (69.1% vs. 39.4%, [p=0.0001]) were found to be the most frequently omitted medications. There were also considerably more medication omissions in patients prescribed with more medications (median number: 4, I QR [2, 6] vs. median number: 2, IQR [2, 4], [p=0. 0.001]). The most common reason for the omission was medication unavailability (89.3%), followed by work overload (71.4%), and the patient is off the ward (71.4%).Conclusions: This study revealed that medication omissions are a continuing problem and this may result in increased morbidity and mortality rates. There is a need to put in place specific strategies to reduce this problem.
