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. 

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. 

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%) (>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 >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

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.

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.

Substandard and falsified medical product recalls in Zambia from 2018 to 2021 and implications on the quality surveillance systems

BACKGROUND: Substandard and falsified (SF) medical products are removed from circulation through a process called 'product recall' by medicines regulatory agencies. In Zambia, the Zambia Medicines Regulatory Authority (ZAMRA) is responsible for recalling SF medical products from the Zambian market through passive and active surveillance methods. This study aimed to describe the prevalence of recalls of SF medical products and to analyse the frequently recalled therapeutic categories, dosage forms, categories of defects that led to the recalls and their sources with respect to the country of the marketing authorisation holder (MAH) or manufacturer. METHODS: We conducted a descriptive cross-sectional review of the product recalls issued by ZAMRA between January 2018 and December 2021. A search for all medical product alerts and recalls issued by ZAMRA was carried out by reviewing the internal post-marketing surveillance database kept at ZAMRA headquarters. Data were extracted using a structured Excel database and analysed using Microsoft Excel. RESULTS: A total of 119 alerts were received during the review period, of which 83 (69.7%) were product recalls. Oral solid dosage forms were the most recalled dosage form (53%). Furthermore, the number of recalls increased in 2020 (44.6%) and 2021 (22.9%), with the majority (20.5%) of the recalled products being substandard products classified as antiseptics and disinfectants and were attributed to the high demand during the COVID-19 pandemic. Manufacturing laboratory control issues were the reason for product recall in almost half (47.4%) of the cases. Most of the products recalled originated from India (38.6%), followed by Zambia (25.3%). Only one suspected falsified product was recalled between 2018 and 2021. A total of 66 recalls of the 83 products were initiated by ZAMRA, with only 17 voluntarily by foreign MAHs. No product recall was initiated by the local representatives of foreign manufacturers or MAH. CONCLUSION: The majority of the pharmaceutical product recalls in Zambia were substandard products. Manufacturing laboratory control issues lead to most recalls and require investigation of the root causes, preventive action, and strict compliance with the good manufacturing practices guidelines by manufacturers

Familiarity, Knowledge and Practices of Healthcare Professionals Regarding the Pharmacovigilance of Biological Medicines in Lusaka, Zambia: A Multi-Facility Cross-Sectional Study.

Background: Pharmacovigilance of biological medicines is crucial because it ensures that medicines meet the World Health Organization (WHO) standards. In Zambia, there is little information on healthcare professionals’ familiarity, knowledge and practices on the pharmacovigilance of biological and biosimilar medicines. Therefore, this study investigated the familiarity, knowledge, and practices related to the pharmacovigilance (PV) of biological and biosimilar medicines at selected hospitals in Lusaka, Zambia. Methods: The study was an analytical questionnaire-based cross-sectional study conducted among healthcare professionals (HCPs) at the Adult hospital, Cancer Diseases hospital, Paediatrics hospital and Women and New Born Hospital in Lusaka. Data were collected over four weeks in May and June 2021 and subsequently analysed using IBM SPSS version 21. The statistical significance was set at a 95% confidence interval. Results: Of 245 participants, only 115 (48.9%) of the HCPs were familiar with biological medicines to a basic understanding. Regarding the term biosimilars, most of the HCPs (40.9%) never heard of this word. The mean score for knowledge regarding the PV considerations of biological medicines was 4.1 out of 8 questions. Most HCPs used non-proprietary names (44.2%) when prescribing, dispensing, or administering biological medicines. Additionally, more than half (57.3%) of HCPs did not record batch numbers when dispensing or administering biological medicines. Conclusion: Healthcare professionals were more familiar with the term biological medicines than biosimilars. Healthcare professionals generally scored poorly when their knowledge regarding the PV considerations of biological medicines was assessed. Thus, there is a need to provide adequate training and continuous professional development among healthcare professionals on the pharmacovigilance of biological and biosimilar medicines

Knowledge and practices toward COVID-19 among healthcare students: A cross-sectional study at the University of Zambia

BACKGROUND: The COVID-19 pandemic led to the disruption of physical classes for university students globally, as large gatherings fuelled the transmission of the virus. In the efforts to mitigate its transmission and return to normality, prevention measures, including vaccination, have been encouraged. Therefore, it is critical to understand the knowledge and practices of students regarding COVID-19. This study assessed the knowledge and practices toward COVID-19 among healthcare students at the University of Zambia. MATERIALS AND METHODS: This questionnaire-based cross-sectional study was carried out from August 2021 to October 2021 among 478 healthcare students (pharmacy, physiotherapy, nursing, biomedical, medicine, and radiography). We used a previously validated questionnaire to measure knowledge and practice. The predictors of knowledge and practices were assessed using logistic regression with robust estimation of standard errors. Statistical analysis was conducted using Stata/BE version 17.0. RESULTS: Of the 478 respondents, 243 (50.8%) were females. A larger proportion, 175 (36.6%) were in Pharmacy training, and 156 (32.6%) were in their fifth year of study. The overall mean knowledge score of the participants was 87.9 (SD = 16.1), being higher at 89.6 (SD = 14.3) among medical students and the lowest at 86.7 (SD = 17.1) among Pharmacy students, although this was statistically non-significant (p = 0.488). The overall mean practice score was 60.0 (SD = 24.7), being significantly higher at 63.5 (23.4) among nursing, physiotherapy and environmental students compared to other students (p = 0.048). In multivariable analysis, the participant training program was non-significantly associated with knowledge and practice toward COVID-19. However, increased age (AOR = 1.09, 95% CI: 1.01-1.117) and residing in urban areas (AOR = 1.79, 95% CI: 1.07-3.01) than in rural areas were associated with higher odds of good practice toward COVID-19. CONCLUSION: The healthcare students generally showed good knowledge levels and poor practices toward COVID-19. Further, there was no evidence of a difference in knowledge of COVID-19 among healthcare students. These findings suggest the need for implementation strategies to be centered on improving the practices of students toward COVID-19

Awareness and acceptance of COVID-19 vaccines and associated factors among pharmacy students in Zambia

Background: Several vaccines have been developed and administered since coronavirus disease 2019 (COVID-19) was declared a pandemic in March 2020. In April 2021, the authorities in Zambia administered the first doses of the Oxford-AstraZeneca® COVID-19 vaccine. Objective: To assess the awareness and acceptance of COVID-19 vaccines and associated factors among pharmacy students in Zambia. Methods: A cross-sectional study among 326 undergraduate pharmacy students in Lusaka, Zambia, from February through to 25 April 2021. Data were analysed using Stata version 16.1. Multivariable logistic regression was used to determine factors influencing vaccine acceptance. Results: Of the 326 participants, 98.8% were aware of the COVID-19 vaccines, but only 24.5% would accept vaccination. Being of Christian faith was associated with reduced odds of awareness of the COVID-19 vaccine (aOR=0.01; 95% CI: 0.01-0.20). Compared to females, male respondents were 86% more likely to accept the vaccine if it was made available (aOR=1.86; 95% CI: 1.10-3.14). Unmarried compared to married respondents were 2.65 times as likely to accept vaccination (aOR=2.65; 95% CI: 1.06-6.63) whilst unemployed respondents were less likely to accept vaccination (aOR=0.32; 95% CI: 0.16-0.46). Barriers to the acceptability of the vaccine were possible side effects (78.5%) and scepticism about its effectiveness to prevent COVID-19 (10.2%). Conclusion: There was significant vaccine hesitancy toward COVID-19 vaccines among Zambian pharmacy students despite their awareness of the vaccines. Health authorities must work collaboratively with training institutions to mitigate vaccine hesitancy, especially with healthcare students being a key part of the future healthcare workforce overseeing disease prevention strategies

Student’s perspectives, satisfaction and experiences with online and classroom learning during the COVID-19 pandemic : findings and implications on blended learning

Objectives: The coronavirus disease 2019 (COVID-19) pandemic disrupted classroom-based learning, necessitating the adoption of online learning in most universities. However, there has been a lack of information on university students' perspectives regarding online learning during the COVID-19 pandemic. This study assessed the perspectives, satisfaction, and experiences with online and classroom learning among human health students at the University of Zambia. Methods: This cross-sectional study was conducted among 737 students at the University of Zambia from October 2022 to April 2023. Data were analysed using Stata version 16.1. Results: Of the 737 participants, 51.6% were female and 56.5% agreed that blended learning should continue even after the COVID-19 pandemic. However, 78.4% of the students believed that group discussions were more suitable in the classroom than online learning. Most students (67.1%) disagreed that they preferred online learning to classroom learning. Further, 77.6% of the students disagreed that online learning gave more satisfaction than classroom learning. Conclusions: This study found that most students recommended the continuation of blended learning after the pandemic. However, they believed that follow-up tutorials and assessments were better undertaken in physical classrooms than online learning. These findings are important in sensitising stakeholders in the education sector and governments to consider blended learning as a teaching strategy in the future. There is a need to develop and implement curricula that offer blended learning to students as well as ensure the students have the necessary facilities and equipment to support such learning
