Knowledge and perception of antimicrobial resistance and antimicrobial stewardship among healthcare students in Nigeria.

Background: Assessment of knowledge and perception of healthcare students regarding antimicrobial resistance (AMR) and antimicrobial stewardship (AMS) would facilitate more effective education of these future prescribers. Objectives: To assess knowledge and perception of AMR and AMS among healthcare students in Nigerian universities. Methods: This was a questionnaire-based, cross-sectional survey of medical, nursing and pharmacy undergraduate students from November 2019 to January 2020, using both paper and electronic modes of self-administration. Results: A total of 335 students participated in the survey. Mean age of respondents was 23±3 years; 114 (34.4%) were in their 5th year of study. Most (78.9%) of the respondents agreed that widespread use of antimicrobials promotes AMR. Only 70 (21.1%) were aware that poor hand hygiene promotes AMR; 45.9% (42.7%, 37.3% and 57.7% for medicine, nursing and pharmacy respectively, p = 0.007) agreed that AMR is promoted by substandard quality of antimicrobials. Majority (94.3%) perceived AMR as a worldwide problem. Over half (60.8%) were not familiar with the term 'antimicrobial stewardship'. Eleven (3.3%) and 122 (36.9%) rated their AMS knowledge as 'very good' and 'poor' respectively. Conclusions: Nigerian healthcare students had suboptimal knowledge of AMR and AMS. Current undergraduate healthcare curriculum should be reviewed to incorporate AMS principles.

Microbial contamination of packaged drinking water in Nigeria.

OBJECTIVES: About 18% of urban households in Nigeria depend on packaged sachet water as the primary source of drinking water. This review assessed microbial contamination of these products with an emphasis on total coliforms and the faecal indicator bacteria (FIB) - Escherichia coli (E. coli) and thermotolerant coliforms (TTC). METHODS: PubMed/Medline, African Index Medicus, AfroLib, Global Health Library, Embase and the ISI Web of Science databases were searched to identify original research published up to October 2020. The literature findings were synthesised narratively in line with the review objectives. To assess prevalence of microbial contamination, a random effects meta-analysis, was also conducted using the R metafor package in RStudio. The protocol for this review is registered on PROSPERO with reference number CRD 42019128474. RESULTS: Fifty-two of 429 studies were identified for inclusion. At 53.27%, contamination prevalence was higher for total coliforms (95% CI: 39.05-66.98, I2  = 81%, p < 0.01, 42 studies) than FIB (12.38%, 95% CI: 7.92-18.85, I2  = 61%, p < 0.01, 33 studies) suggesting that treatment failure is a major contributor to the poor microbial quality reported in the included studies. Within the FIB group, the prevalence of contamination with E. coli was 13.30% (95% CI: 8.23-20.80, I2  = 65%, p < 0.01, 27 studies) versus 6.24% (95% CI: 1.12-28.06, I2  = 72%, p < 0.01, six studies) for TTCs. Other microbial contaminants reported were Pseudomonas aeruginosa, Klebsiella and Enterococcus faecalis and these showed multidrug antibiotic resistance. CONCLUSIONS: The findings of this review highlight the need for improved regulatory oversight with more stringent monitoring of the microbial quality of sachet water products in Nigeria.

Clinical pharmacy services provided in public sector hospitals in Nigeria: a national survey.

OBJECTIVES: Studies show that clinical pharmacy services are effective in optimizing medicines use and patients' outcomes. This study aimed to determine the clinical pharmacy services provided in public sector hospitals in Nigeria. METHODS: This was an online survey of 296 primary, secondary and tertiary care hospitals sampled purposively across the 36 States and Federal Capital Territory in Nigeria. Data analysis was conducted descriptively via χ 2 test and multivariate analysis of variance (MANOVA). KEY FINDINGS: Responses were obtained from 272 hospitals in the country with a survey completion rate of 88%. This included 55 tertiary, 72 secondary and 145 primary healthcare centres (PHCs). Pharmacists provided pharmaceutical care services in all the tertiary care hospitals, 94% of the secondary and in only 6% of the PHCs surveyed. Most of the secondary and tertiary care hospitals provided medicines information, patient education and counselling, and in-patient dispensing services [n = 97 (79%), 116 (94%), 88 (72%)], respectively. However, fewer than a third reported involvement in multidisciplinary ward rounds, medication chart review and antibiotic stewardship programmes [n = 18 (15%), 33 (27%), 22 (18%), respectively]. Furthermore, medication error reporting and pharmacovigilance services were each routinely provided in only about half of the secondary and tertiary care hospitals [n = 62 (50%)], and this was not associated with the level of care (P > 0.05). CONCLUSIONS: The findings of this study demonstrate disparity in clinical pharmacy service availability across the various levels of care in Nigeria and emphasize the need to prioritize their integration within the primary care sector.

Implementation of antimicrobial stewardship programmes in African countries: a systematic literature review.

OBJECTIVE: Antimicrobial stewardship is one of the strategic objectives of the WHO global action plan on antimicrobial resistance. This paper sought to review the extent of implementation of antimicrobial stewardship programmes (ASPs) in African countries and the reported outcomes. METHODS: We searched five electronic databases, including PubMed, Scopus, Cochrane library, African Journal Online, CINAHL and Google scholar for papers published between 1990 and March 2019. We combined the names of countries in the five regions of Africa with antimicrobial stewardship terms. Studies of any design, employing any stewardship strategies were included. The quality of included studies was assessed using the National Heart, Lung and Blood Institute (NHLBI) quality assessment tool for before and after studies. RESULTS: Of 1752 titles identified, 13 studies met the criteria for inclusion. Seven of the studies were conducted in South Africa, three in Kenya and one each in Sudan, Tanzania and Egypt. Eleven studies were of high quality with low risk of bias. The included studies mainly assessed the outcome using process measures and these were associated with improved compliance with antibiotic guidelines, appropriateness of prescribing, reduction in antibiotic use and cost savings. Decrease in rate of surgical site infections and nonsignificant change in mortality and 30-day readmission rate were reported in two studies respectively. CONCLUSION: Findings of this review show the paucity of data on implementation of ASPs in African countries. Although the continent is faced with challenges which impact on effective implementation of ASPs, the successes reported in the included studies show that other African countries can implement these programmes.

Antimicrobial Stewardship Programmes in Community Healthcare Organisations in England: A Cross-Sectional Survey to Assess Implementation of Programmes and National Toolkits.

OBJECTIVE: The aim of this study was to assess antimicrobial stewardship activities in Community Healthcare Organisations (CHOs) with focus on the implementation of the two national antimicrobial stewardship toolkits, TARGET (Treat Antibiotics Responsibly, Guidance, Education, Tools) and SSTF (Start Smart, then Focus). The study utilised a web-based survey comprising 34 questions concerning antimicrobial policies and awareness and implementation of antimicrobial stewardship toolkits. This was distributed to pharmacy teams in all 26 CHOs in England. Twenty CHOs (77%) responded. An antimicrobial stewardship (AMS) committee was active in 50% of CHOs; 25% employed a substantive pharmacist post and 70% had a local antibiotic policy. Fourteen of the responding CHOs were aware of both AMS toolkits, five organisations were aware of either SSTF or TARGET, and one organisation was not aware of either toolkit. Of the organisations aware of SSTF and TARGET, eight had formally reviewed both toolkits, though three had not reviewed either. Less than half of the respondents had developed local action plans for either toolkit. National guidance in England has focused attention on initiatives to improve AMS implementation in primary and secondary care; more work is required to embed AMS activities and the implementation of national AMS toolkit recommendations within CHOs.

A Review of Quality Measures for Assessing the Impact of Antimicrobial Stewardship Programs in Hospitals.

The growing problem of antimicrobial resistance (AMR) has led to calls for antimicrobial stewardship programs (ASP) to control antibiotic use in healthcare settings. Key strategies include prospective audit with feedback and intervention, and formulary restriction and preauthorization. Education, guidelines, clinical pathways, de-escalation, and intravenous to oral conversion are also part of some programs. Impact and quality of ASP can be assessed using process or outcome measures. Outcome measures are categorized as microbiological, patient or financial outcomes. The objective of this review was to provide an overview of quality measures for assessing ASP and the reported impact of ASP in peer-reviewed studies, focusing particularly on patient outcomes. A literature search of papers published in English between 1990 and June 2015 was conducted in five databases using a combination of search terms. Primary studies of any design were included. A total of 63 studies were included in this review. Four studies defined quality metrics for evaluating ASP. Twenty-one studies assessed the impact of ASP on antimicrobial utilization and cost, 25 studies evaluated impact on resistance patterns and/or rate of Clostridium difficile infection (CDI). Thirteen studies assessed impact on patient outcomes including mortality, length of stay (LOS) and readmission rates. Six of these 13 studies reported non-significant difference in mortality between pre- and post-ASP intervention, and five reported reductions in mortality rate. On LOS, six studies reported shorter LOS post intervention; a significant reduction was reported in one of these studies. Of note, this latter study reported significantly (p < 0.001) higher unplanned readmissions related to infections post-ASP. Patient outcomes need to be a key component of ASP evaluation. The choice of metrics is influenced by data and resource availability. Controlling for confounders must be considered in the design of evaluation studies to adequately capture the impact of ASP and it is important for unintended consequences to be considered. This review provides a starting point toward compiling standard outcome metrics for assessing ASP.
