Training of pharmacists in Zambia: developments, curriculum structure and future perspectives

In Zambia, local training of pharmacists commenced in 2001. Development of pharmaceutical education in Zambia has been largely influenced by the national need for pharmacists in the healthcare sector. Training institutions offer the Bachelor of Pharmacy (B.Pharm.) degree programme which follows a four-year curriculum structure. The B.Pharm. programme aims to produce pharmacists with requisite competences to practise pharmaceutical care and sustain the development of pharmacy in Zambia. Seventeen years down the line, Zambia continues to advance local pharmaceutical education programmes. Over 700 pharmacists have graduated from the national training programmes in Zambia which continue to address the pharmaceutical workforce needs. Pharmaceutical education in Zambia offers a number of career prospects in hospital, community, pharmaceutical manufacturing, medicine regulation, public health administration, and progression to academia. Positive transitions made to advance pharmacists’ training in Zambia give a positive outlook for the future

Antimicrobial stewardship knowledge and perception among physicians and pharmacists at leading tertiary teaching hospitals in Zambia: implications for future policy and practice

Antimicrobial stewardship (AMS) is a key strategy promoting rational antimicrobial use. In Zambia, information on health professionals’ knowledge, attitude, and practice of AMS is limited. This study was undertaken to address this at Zambia’s leading specialized teaching hospitals. Descriptive, cross-sectional study involved 137 physicians and 61 pharmacists. AMS knowledge was relatively low among physicians (51%) and pharmacists (39%). Few physicians (9%) and pharmacists (20%) demonstrated sufficient knowledge of the basic principles of AMS. Physicians’ and pharmacists’ knowledge levels were significantly associated with years of practice, job position or practice rank, and previous AMS training. The majority (95%) perceived AMR as a current problem in their practise. Most physicians (92%) and pharmacists (86%) had not undertaken AMS training before. All indicated the need for context-specific educational interventions to promote AMS in Zambia. Despite positive perceptions, basic knowledge of AMS was relatively low. Context-specific educational interventions and capacity building are needed to address AMS gaps

Evidence on the cost-effectiveness of lifelong antiretroviral therapy for prevention of mother-to-child transmission of HIV : implications for resource-limited countries in sub-Saharan Africa

Introduction: The 2016 World Health Organization (WHO) consolidated guideline recommends lifelong antiretroviral therapy (ART) for all HIV-infected pregnant and breastfeeding women for preventing mother-to-child HIV transmission (PMTCT). Ambiguity remains about the cost-effectiveness of this strategy in resource-limited developing countries. Areas Covered: We reviewed model-based studies on the cost-effectiveness of lifelong ART (formerly Option B+) relative to previous WHO guidelines for PMTCT. Our search using PubMed, Medline and Google Scholar for articles on Option B+ resulted in the final inclusion of seven studies published between 2012 and 2016. The Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist was used to assess the quality of reporting. Outcomes of interest, which included infant infections averted, maternal quality and length of life, and the Incremental Cost Effectiveness Ratio (ICER), were used in comparing cost-effectiveness. Expert Commentary: Despite most model-based studies favouring lifelong ART (Option B+) in terms of cost-effectiveness in comparison to Options A and B, inclusiveness of the evidence remains weak for generalization largely because setting specificity for providing lifelong ART to all pregnant and breastfeeding women may differ significantly in each setting. Therefore, future cost-effectiveness studies should be robust, setting-specific, and endeavor to assess the willingness and ability to pay of each setting

Impact of the coronavirus disease on the mental health and physical activity of pharmacy students at the University of Zambia: a cross-sectional study

Background: The novel coronavirus disease (COVID-19) is a serious global health problem that has negatively impacted the mental health of students.Methods: We conducted an online descriptive cross-sectional study among 273 undergraduate pharmacy students at the University of Zambia from August to September 2020. A partial proportional odds regression model was used to determine the predictors of anxiety. All statistical tests were set at 95% confidence level (p<0.05).Results: A response rate of 70% was obtained with the majority of the students being female 51.6%. Of the 273 respondents, 23.8% did not experience anxiety, 34.4% experienced mild anxiety, 24.9% experienced moderate anxiety while 16.9% experienced severe anxiety about COVID-19. It was also found that 61.2% of students reported that their attention to mental health increased during the COVID-19 pandemic whereas 44.3% reported an increased resting time with a significant reduction in relaxation 51.3% and physical activity 45.4% time. Factors that affected mental health included; reduced family care (OR: 2.27; 95% CI: 1.09-4.74), not changing attention to mental health (OR: 0.33; 95% CI: 0.18-0.62), being in the final year of study (OR: 0.33; 95% CI: 0.13-0.84), reduced time of resting (OR: 2.10; 95% CI: 1.26-3.50) and feeling helpless (OR: 0.42; 95% CI:0.23-0.75).Conclusions: COVID-19 negatively impacted the mental health and physical activity of pharmacy students at the University of Zambia. This can have negative health and academic outcomes for students going forward. Higher learning institutions and key stakeholders should implement measures to aid students to recover from the impact of COVID-19 on their mental health and physical activity

Tryptophan, glutamine, leucine, and micronutrient supplementation improves environmental enteropathy in Zambian adults: a randomized controlled trial.

BACKGROUND: Environmental enteropathy (EE) refers to villus blunting, reduced absorption, and microbial translocation in children and adults in tropical or deprived residential areas. In previous work we observed an effect of micronutrients on villus height (VH). OBJECTIVE: We aimed to determine, in a randomized controlled trial, if amino acid (AA) or multiple micronutrient (MM) supplementation can improve intestinal structure or barrier dysfunction in Zambian adults with EE. METHODS: AA (tryptophan, leucine, and glutamine) and/or MM supplements were given for 16 wk in a 2 × 2 factorial comparison against placebo. Primary outcomes were changes in VH, in vivo small intestinal barrier dysfunction assessed by confocal laser endomicroscopy (CLE), and mechanistic (or mammalian) target of rapamycin complex 1 (MTORC1) nutrient responsiveness in lamina propria CD4+ lymphocytes. RESULTS: Over 16 wk AA, but not MM, supplementation increased VH by 16% (34.5 μm) compared with placebo (P = 0.04). Fluorescein leak, measured by CLE, improved only in those allocated to both AA and MM supplementation. No effect was seen on MTORC1 activation, but posttreatment MTORC1 and VH were correlated (ρ = 0.51; P = 0.001), and change in MTORC1 was correlated with change in VH in the placebo group (ρ = 0.63; P = 0.03). In secondary analyses no effect was observed on biomarkers of microbial translocation. Metabolomic analyses suggest alterations in a number of microbial- and host-derived metabolites including the leucine metabolite β-hydroxy-β-methylbutyrate, which was increased by AA supplementation and correlated with VH. CONCLUSIONS: In this phase 2 trial, AA supplementation protected against a decline in VH over the supplementation period, and improved barrier function when combined with micronutrients. Leucine and MTORC1 metabolism may be involved in the mechanism of effect. This trial was registered at www.pactr.org as PACTR201505001104412

Prescribers' experiences of, and attitudes to, use of morphine for palliative care at a tertiary hospital in Zambia

Objective: To explore medical doctors' experiences of, and attitudes to, use of morphine for palliative care at a tertiary hospital in Zambia. Methods: A qualitative, exploratory case study was undertaken. Semi-structured interviews were used to collect data from 14 medical doctors working in the fields of oncology, pediatrics, and internal medicine at a tertiary hospital in Lusaka, Zambia, regarding their experiences and attitudes to prescribing morphine for palliative care. Thematic analysis of interview transcripts was carried out to establish common themes in the data. The study was approved by BSMS and UNZA research ethics committees. Results: All participants agreed that doctors were becoming more comfortable with the prescribing of morphine, although experiences were notably different for doctors working in oncology, compared to other departments. Themes of difficulty discussing end-of-life, poor recognition of pain, and fear of patient addiction, were more prominent in the responses of non-cancer doctors. Morphine use was generally restricted to cancer and sickle cell disease patients, with most non-cancer doctors stating that they rarely prescribe morphine for outpatient use. Training in pain management and the presence of a palliative care team were perceived to be facilitators to morphine prescribing. Conclusions: Although there is an increased willingness to prescribe morphine, limited knowledge of pain management, especially for nonmalignant disease, underlies many of the findings in this study. Opportunity exists for professional development in pain management to further improve the acceptance and use of opioids in palliative care, especially for out-patients

Synthesis of enantiomerically pure (d) – doxylamine using a novel chiral auxiliary

It is known that the main mode of synthesis of doxylamine is a racemic mixture. However, the active enantiomers of the compound show superior activity to that of the racemate, thus the need to synthesize doxylamine as an enantiopure compound. This study aimed to synthesise an enantiopure (d)-doxylamine and it was achieved through the use of optically active diols synthesised from a novel chiral auxiliary. While most available methods employ Sharpless asymmetric dihydroxylation, this study reports a method that achieves superior enantiomeric excess with consequent better yields of 67% of end products not easily accessible by use of Sharpless Asymmetric Dihydroxylation

Healthcare professionals' knowledge of pharmacogenetics and attitudes towards antimicrobial utilization in Zambia : implications for a precision medicine approach to reducing antimicrobial resistance

Introduction: Sub-Saharan Africa and other low- and middle-income countries (LMICs) have the highest rates of antimicrobial resistance (AMR) driven by high rates of antimicrobial utilization. This is a concern as AMR appreciably increases morbidity, mortality and costs. Pharmacogenetics (PGx) and precision medicine are emerging approaches to combat AMR. Consequently, as a first step there is a need to assess AMR knowledge and attitudes, and knowledge of PGx, among healthcare professionals and use the findings to guide future interventions. Methodology: We conducted a cross-sectional study involving 304 healthcare professionals at tertiary hospitals in Lusaka, Zambia. Structural Equation Modeling (SEM) was used to analyze relationships among latent variables. Results: Overall correctness of answers concerning AMR among healthcare professionals was 60.4% (7/11). Knowledge of pharmacogenetics was low (38%). SEM showed that high AMR knowledge score correlated with a positive attitude toward combating AMR (p < 0.001). Pharmacists had relatively higher AMR knowledge scores (mean = 7.67, SD = 1.1), whereas nurses had lower scores (mean = 5.57, SD = 1.9). A minority of respondents [31.5% (n = 95)] indicated that poor access to local antibiogram data promoted AMR, with the majority [56.5% (n = 190)] responding that poor adherence to prescribed antimicrobials can lead to AMR. Pharmacists had the highest scores for attitude (mean = 5.60, SD = 1.6) whereas nurses had the lowest scores (mean = 4.02, SD = 1.4). Conclusion: AMR knowledge and attitudes, as well as knowledge on PGx among healthcare professionals in Zambia, is sub-optimal and has the potential to affect the uptake of precision medicine approaches to reduce AMR rates. Educational and positive behavioral change interventions are required to address this and in future, we will be seeking to introduce these to improve the use of antimicrobials
