Healthcare Professionals' Knowledge of Pharmacogenetics and Attitudes Towards Antimicrobial Utilization in Zambia: Implications for a Precision Medicine Approach to Reducing Antimicrobial Resistance

Global knowledge, attitudes, and practices towards antimicrobial resistance among healthcare workers: a systematic review and meta-analysis

BACKGROUND

The rising prevalence of antimicrobial resistance (AMR) poses a critical global health challenge. Healthcare workers (HCWs) play a pivotal role in combating AMR by implementing effective preventive strategies and adhering to good practices. This study aimed to evaluate the global knowledge, attitudes, and practices (KAP) of HCWs towards AMR.

METHODS

A comprehensive search of PubMed/MEDLINE, ScienceDirect, Scopus, Web of Science, Cochrane Library, and Google Scholar was conducted for English-language articles published up to August 2024. Inclusion criteria were observational studies reporting KAP data among HCWs related to AMR. Study quality was assessed using the Joanna Briggs Institute critical appraisal checklist. Statistical analyses, including heterogeneity (I² statistic, Cochran Q), were conducted using STATA version 14. Random-effects models were applied for pooled estimates, and subgroup analyses, meta-regression, and sensitivity analyses were performed. Publication bias was assessed via Egger's test and adjusted using the trim-and-fill method. Geographical distribution was analyzed with ArcGIS 10.3 software, and evidence certainty was evaluated using the GRADE framework.

RESULTS

A meta-analysis of 108 studies involving 29,433 HCWs assessed their knowledge of AMR. Additionally, 51 studies with 13,660 HCWs evaluated attitudes, and 43 studies with 10,569 HCWs examined practices regarding AMR. The pooled proportion of HCWs with good knowledge of AMR was 56.5% (95% CI: 50.4-62.6%, I² = 99.5%), with the highest prevalence in Europe (70.3%) and the lowest in the Western Pacific (45.9%). Positive attitudes towards AMR were reported in 60.4% (95% CI: 48.5-72.3%, I² = 99.8%), with the highest prevalence in the Eastern Mediterranean Region (64.5%) and among those with less than five years of experience (77.8%). Good practices were observed in 48.5% (95% CI: 36.5-60.5%, I² = 99.7%), with the highest adherence in Europe (56.6%) and the lowest in Africa (39.1%). Subgroup analysis revealed that younger HCWs (under 30 years) showed better KAP scores across all domains.

CONCLUSION

The findings underscore the need for targeted interventions to enhance the knowledge, attitudes, and practices of HCWs regarding AMR. Priority should be given to designing and implementing robust training programs tailored to the specific needs of HCWs in resource-constrained settings. Strengthening AMR-related education and practice among HCWs is crucial for combating the global AMR crisis effectively.

Impact of a hub-and-spoke approach to hospital antimicrobial stewardship programmes on antibiotic use in Zambia

Background

Antimicrobial stewardship programmes (ASPs) aim to optimize antibiotic use and prevent antimicrobial resistance.

Objective

This study assessed the impact of ASPs, initiated using a hub-and-spoke approach, on antibiotic use in Zambian public hospitals.

Methods

A pre-post study was conducted in 10 ASP-naive hospitals across Zambia using the Centers for Disease Control and Prevention (CDC)'s hospital-based ASP core elements (i.e. leadership, accountability, pharmacy expertise, stewardship actions, tracking progress, reporting and education) checklist and the global point prevalence survey methodology. The intervention involved technical staff from a national 'hub' hospital with an established ASP providing on-site orientation and mentorship to multidisciplinary teams of healthcare workers at 10 'spoke' hospitals to build capacity in antimicrobial stewardship. ASP core elements and inpatient antibiotic use prevalence (AUP) were assessed before and 12 months after ASP implementation. Data were statistically analysed.

Results

The adoption of ASP core elements improved significantly (P = 0.001, 95% CI: -17.8 to -5.42). AUP decreased from 50.1% (±5.8, n = 1477) to 44.3% (±4.6, n = 1400) after 12 months, though the reduction was not statistically significant (P = 0.442; 95% CI: -9.8 to 21.6), with 'Watch' list antibiotics remaining the most commonly prescribed across the hospitals.

Conclusions

The hub-and-spoke approach successfully catalysed ASPs in public hospitals in Zambia, demonstrating the potential for improving antibiotic use practices over time, provided structural challenges are addressed. This approach and insights can guide stakeholders in Zambia and similar settings in enhancing hospital ASPs.

Healthcare providers' knowledge of cardiovascular disease risk after preeclampsia: A pilot of five healthcare facilities in Lusaka, Zambia

OBJECTIVE

To assess Healthcare providers (HCPs') knowledge of cardiovascular disease risk after preeclampsia across five healthcare facilities in Lusaka, Zambia.

STUDY DESIGN

A cross-sectional study was conducted at selected health facilities in Lusaka Zambia from August 5, 2023, to October 31, 2023. A self-administered questionnaire was distributed among obstetricians, general practitioners, registered nurse midwives, registered nurses, enrolled nurses, enrolled midwives, medical licentiates, and registered public health nurses. The knowledge scores were calculated for each participant, and Logistic regression was used to assess the predictors of high knowledge of cardiovascular disease risk after preeclampsia.

MAIN OUTCOME

The overall mean knowledge score of cardiovascular disease risk after preeclampsia was 4.7/7 (67.1 %). The majority correctly reported hypertension 101 (92.7 %), Ischemic heart disease 84 (77.1 %), Stroke 83 (76.2 %), and kidney disease 75(68.8 %) as future conditions associated with preeclampsia. Knowledge and practice had a significant but moderate negative correlation (r = -0.21, p = 0.037). Compared to obstetricians/general practitioners, registered nurse midwives (adjusted odds ratio [aOR] = 0.21, 95 % CI: 0.05-0.80, p = 0.023) and enrolled midwives/enrolled nurses/medical licentiates/registered public health nurses (aOR = 0.15, 95 % CI: 0.03-0.91, p = 0.039) were less likely to have high knowledge. Additionally, HCPs with 5-10 years (aOR = 7.15, 95 % CI: 1.99-25.72, p = 0.003) and more than 15 years of work experience (aOR = 3.21, 95 % CI: 1.03-9.99, p = 0.017) were more likely to have high knowledge than those with less than five years.

CONCLUSION

Most HCPs were knowledgeable about the future risk of cardiovascular diseases after preeclampsia. Nevertheless, positive behavioral change interventions may be required to address the disconnect between knowledge and practice.

Scholarly literature on nurses and pharmacogenomics: A scoping review

BACKGROUND

Pharmacogenomics is the bioscience investigating how genes affect medication responses. Nurses are instrumental in medication safety. Pharmacogenomics is slowly being integrated into healthcare, and knowledge and understanding of it is now pertinent to nursing practice.

PURPOSE

This paper aims to map the scholarly literature on pharmacogenomics in relation to nurses.

METHODS

A scoping review was conducted in four databases: CINAHL, Embase (Ovid), ProQuest Health and Medicine and PubMed using the search terms pharmacogenomic*, pharmacogenetic*, PGx*, and nurs*, resulting in 263 articles of which 77 articles met the inclusion criteria.

FINDINGS

Most articles (85 %, n = 65) were non-empirical and 12 presented empirical data (15 %, n = 12). The articles were USA-centric (81 %, n = 62) and represented a broad range of nursing specialties.

CONCLUSION

The majority of scholarly literature on nurses and pharmacogenomics is narrative reviews. Further empirical research is warranted to investigate nurses' current knowledge levels and potential involvement with pharmacogenomics in clinical practice.

Qualitative assessment of knowledge, attitude and practice of oncologists about precision medicine in cancer patients- study from Lahore, Pakistan

BACKGROUND

Precision medicine (PM) is in great progressive stages in the West and allows healthcare practitioners (HCPs) to give treatment according to the patient's genetic findings, physiological and environmental characteristics. PM is a relatively new treatment approach in Pakistan Therefore, it is important to investigate the level of awareness, attitude, and challenges faced by oncology physicians while practicing PM for various therapies, especially cancer treatment.

OBJECTIVES

The present study aims to explore the level of awareness, attitude, and practice of PM in Pakistan along with the challenges faced by the oncologists for the treatment of cancer using the PM approach.

METHODS

Phenomenology-based qualitative approach was used. Face-to-face in-depth interviews were conducted using the purposive sampling approach among oncologists in Lahore, Pakistan. The data were analyzed using thematic content analysis to identify themes and sub-themes.

RESULTS

Out of 14 physicians interviewed 11 were aware of PM. They were keen on training to hone their skills and agreed on providing PM. Oncologists believed PM was expensive and given to affluent patients only. Other impeding factors include cost, lack of knowledge, and drug unavailability.

CONCLUSIONS

Despite basic knowledge and will to practice, resource and cost constraints were marked as significant barriers. Additional training programs and inclusion into the curriculum may help to pave the way to PM implementation in the future. In addition, health authorities and policymakers need to ensure a cheaper PM treatment can be made available for all cancer patients.

Antibiotic resistance in Sudan: assessing the knowledge and practices of healthcare workers in Khartoum

Background

Antibiotic resistance (ABR) is a major public health issue, associated with increased patient morbidity and mortality globally, with significantly higher rates in low- and middle-income countries (LMICs). Assessment of contextual factors, such as information, education, infrastructure and regulations are important for developing local solutions against ABR.

Objectives

To determine the knowledge and practices of healthcare workers (HCWs) towards ABR in hospitals in Sudan.

Materials and methods

A survey was conducted in three different hospitals in Khartoum, Sudan from February to December 2020. HCWs of different specialties and expertise were invited to participate. Data were descriptively analysed using Statistical Package for Social Sciences (SPSS).

Results

ABR was identified as a big challenge by 89% of 345 HCWs who participated. The results show that 79% of doctors don't rely on the clinical microbiology laboratory (CML) results for antibiotic prescription or clinical decision-making. Sixty percent of HCWs agreed there are infection prevention and control (IPC) guidelines in their hospital, but 74% of them don't have access to them, and infrequently receive relevant IPC training. Furthermore, HCWs obtain ABR information from other colleagues informally, not through local data or reports.

Conclusions

Despite adequate knowledge of ABR locally, there are significant contextual technical challenges facing HCWs in Sudan, such as availability of policies and accurate data from CMLs. The results indicate a poor link between HCWs and the CMLs for infection management and it is essential to improve communication between the different hospital departments with regard to ABR transmission, and ensure the effectiveness of local IPC policies based on locally available data.

The Case for Pre-Emptive Pharmacogenetic Screening in South Africa

Lack of equitable representation of global genetic diversity has hampered the implementation of genomic medicine in under-represented populations, including those on the African continent. Data from the multi-national Pre-emptive Pharmacogenomic Testing for Preventing Adverse Drug Reactions (PREPARE) study suggest that genotype guidance for prescriptions reduced the incidence of clinically relevant adverse drug reactions (ADRs) by 30%. In this study, hospital dispensary trends from a tertiary South African (SA) hospital (Steve Biko Academic Hospital; SBAH) were compared with the drugs monitored in the PREPARE study. Dispensary data on 29 drugs from the PREPARE study accounted for ~10% of total prescriptions and ~9% of the total expenditure at SBAH. VigiLyze data from the South African Health Products Regulatory Authority were interrogated for local ADRs related to these drugs; 27 were listed as being suspected, concomitant, or interacting in ADR reports. Furthermore, a comparison of pharmacogene allele frequencies between African and European populations was used to frame the potential impact of pre-emptive pharmacogenetic screening in SA. Enumerating the benefit of pre-emptive pharmacogenetic screening in SA will only be possible once we initiate its full application. However, regional genomic diversity, disease burden, and first-line treatment options could be harnessed to target stratified PGx today.

Education and Awareness on Antimicrobial Resistance in the WHO African Region: A Systematic Review

This review documents the status of AMR education and awareness in the WHO African region, as well as specific initiatives by its member states in implementing education and awareness interventions, as a strategic objective of the Global Action Plan on AMR, i.e., improve knowledge and understanding on AMR through effective communication, education, and training. A systematic search was conducted in Google Scholar, PubMed, and African Journals Online Library according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, for articles published in English. Retrieval and screening of articles was performed using a structured search protocol following a pre-set inclusion/exclusion criterion. Eighty-five published articles reporting 92 different studies from 19 Member States met inclusion criteria and were included in the final qualitative synthesis. Nigeria (21) and Ethiopia (16) had most of the studies, while the rest were distributed across the remaining 17 Member States. The majority of the articles were on knowledge, attitude, and practices with regard to AMR and antimicrobial use and most of them documented a general lack and suboptimal knowledge, poor attitude and practices, and widespread self-medication. This review shows low levels of knowledge of AMR coupled with extensive misuse of antimicrobial medicines by different target audiences. These findings underscore the urgent need for enhanced and context-specific educational and positive behavioural change interventions.

Drivers of antimicrobial resistance in layer poultry farming: Evidence from high prevalence of multidrug-resistant Escherichia coli and enterococci in Zambia

Background and Aim

Inappropriate use of antimicrobials exacerbates antimicrobial resistance (AMR) in the poultry sector. Information on factors driving AMR in the layer poultry sector is scarce in Zambia. This study examined the drivers of AMR in the layer poultry sector in the Lusaka and Copperbelt Provinces of Zambia.

Materials and Methods

This cross-sectional study employed a structured questionnaire in 77 layer poultry farms in the provinces of Lusaka and Copperbelt, Zambia, from September 2020 to April 2021. Data analysis was conducted using Stata version 16.1. Antimicrobial resistance was defined as the presence of multidrug resistance (MDR) isolates. Multivariable regression analysis was used to identify drivers of AMR.

Results

In total, 365 samples were collected, from which 339 (92.9%) Escherichia coli and 308 (84.4%) Enterococcus spp. were isolated. Multidrug resistance was identified in 39% of the E. coli and 86% of the Enterococcus spp. The overall prevalence of AMR in layer poultry farms was 51.7% (95% confidence interval [CI]: 40.3%-63.5%). Large-scale farmers (Adjusted odds ratio [AOR] = 0.20, 95% CI: 0.04%-0.99%) than small-scale and farmers who were aware of AMR than those who were unaware (AOR = 0.26, 95% CI: 0.08%-0.86%) were less likely to experience AMR problems.

Conclusion

This study found a high prevalence of AMR in layer poultry farming linked to the type of farm management practices and lack of AMR awareness. Evidence of high MDR in our study is of public health concern and requires urgent attention. Educational interventions must increase AMR awareness, especially among small- and medium-scale poultry farmers.

Knowledge, attitude and practice towards cervical cancer screening among women living with human immunodeficiency virus: Implication for prevention strategy uptake

AIM

To explore the knowledge, attitude and practices of cervical cancer screening among HIV-infected women in public health facilities in Lusaka, Zambia.

DESIGN

Cross-sectional study.

METHODS

The study was conducted from 1st January 2020 to 28th February 2020. We used a structured questionnaire for data collection. The Structural Equation Modelling (SEM) was used to analyse relationships among latent variables (knowledge, attitude and practice).

RESULTS

The overall knowledge, attitude, and practice scores of cervical cancer screening among women living with HIV were 6.86/11 (62.4%), 6.41/7 (91.6%) and 2.92/8 (36.5%), respectively. Overall, knowledge was positively and significantly associated with attitude (r = .53, p < .001) and practice (r = .38, p < 0.001). Additionally, attitude and practice were significantly associated (r = 0.29, p < .001). Our findings support the reinforcement of current public health interventional programmes to improve the knowledge about cervical cancer and screening uptake.

Investigating Knowledge of Antibiotics, Antimicrobial Resistance and Antimicrobial Stewardship Concepts Among Final Year Undergraduate Pharmacy Students in Northern Nigeria

Introduction

Well trained, knowledgeable and competent pharmacists are indispensable in the fight against antimicrobial resistance (AMR), which is a current global public health problem. The aim of this work was to assess knowledge of antibiotics, antimicrobial resistance and antimicrobial stewardship of fifth year pharmacy students at three universities in Northern Nigeria.

Methods

A descriptive cross-sectional study that used a paper-based questionnaire to collect data from July to September 2021 was conducted. The questionnaire was self-administered and divided into four sections. The first section collected information about the demographic data of respondents, while section B explored their knowledge of antibiotics and AMR. Section C contained six questions assessing knowledge of various aspects of antimicrobial stewardship (AMS), while the final part assessed respondents' preparedness to work with antibiotics and perceptions of their current knowledge of these concepts. Descriptive statistics were used to report the results obtained.

Results

A total of 164 questionnaires were retrieved. Majority of respondents were male (58.3%) and aged between 21 and 25 years (53.4%). Most of them had some knowledge of antibiotics and AMR, however several misconceptions with respect to these concepts were identified. Only 80 (48.8%) of respondents indicated that they knew what AMS was, although most of these students were correctly knowledgeable about the goals and scope of AMS and composition of the AMS team. Generally, less than half of respondents agreed that their current knowledge of antibiotics, AMR or AMS was adequate for their future careers, and over 90% of them agreed that they would like more education about these topics.

Conclusion

Many of the study's' respondents were somewhat knowledgeable about these concepts, although several knowledge gaps were also observed. Improving undergraduate pharmacy education with respect to these concepts is recommended.

Nation-Wide Survey Assessing the Knowledge and Attitudes of Romanian Pharmacists Concerning Pharmacogenetics

Background: Pharmacogenetics (PGx) is an important component of personalized medicine that has the potential to improve medicines' effectiveness and safety. However, despite progress in technology and availability, PGx testing application into patient-care in Eastern Europe countries, has been slow. Objectives: Our aim was to describe knowledge and attitudes of Romanian pharmacists concerning PGx, and identify potential factors limiting PGx implementation. Method: An anonymous, web-based questionnaire was distributed to Romanian pharmacists registered in the National Pharmacists' Association (NPA) via an official e-mail sent by NPA representatives. Results: A total of 1,058 pharmacists completed the questionnaires, resulting in a response rate of 7.6%. Pharmacists were predominantly female (90.1%), younger than 49 years (87.5%) and mostly worked in community pharmacies (80.2%). Most pharmacists (64.8%) had a knowledge score between 30 and 49 points out of 60, and (75.4%) had attitude scores between 9 and 7 out of 10. Attitude and knowledge scores positively correlated. Conclusion: Despite performing fairly well on general questions regarding PGx, Romanian pharmacists may lack in-depth knowledge, which can affect their readiness to discuss PGx information with patients or other healthcare professionals. High pricing was considered an important impediment in PGx implementation.
