Knowledge, attitude and perception on antimicrobial use and antimicrobial resistance among final year medical students in the College of Medicine, Malawi.

Background: Medical curricula need to provide adequate knowledge on antimicrobial medicine use and antimicrobial resistance (AMR). Such knowledge is critical in shaping correct attitudes and perceptions among future prescribers. However, the extent of preparation provided by medical curricula remains unknown. Aim: The current study sought to determine knowledge, attitude and perception on antimicrobial use and AMR among final year medical students in Malawi. Methods: A descriptive cross-sectional study was undertaken among all final year medical students at the College of Medicine, University of Malawi in 2016. Total population sampling and self-administered questionnaires were used. Data were entered using Microsoft Excel and analysed with Epi info. Descriptive analysis for categorical data was done using frequencies and proportions, and for continuous data using measures of central tendency. Results: The response rate in this study was 95%. The mean and median aggregated scores were 7.2 and 7, respectively, for the 11 knowledge questions. Over 88% of the respondents answered more than half of the knowledge questions correctly. Respondents agreed that antimicrobials are overused both at national (50; 69%) and at hospital (52; 72%) levels. Conclusion: This study reports high aggregated knowledge scores on antimicrobial use and resistance with wide variations on correct knowledge scores per question. The study further shows varying level in attitudes and perceptions among medical students. Overall, there were gaps on antimicrobial use and knowledge of AMR which the medical curriculum should addresses.

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.
