Antibiotic Prevalence Study and Factors Influencing Prescription of WHO Watch Category Antibiotic Ceftriaxone in a Tertiary Care Private Not for Profit Hospital in Uganda

Prevalence of antimicrobial use and healthcare-associated infections in the UAE: Results from the first nationwide point-prevalence survey

OBJECTIVES

The WHO's Global Antimicrobial Resistance Surveillance System (GLASS) 2017-2018 reported a significant increase in antimicrobial resistance among nosocomial pathogens. This was the first national point of prevalence survey in United Arab Emirates.

METHODS

A one-day multicenter cross-sectional survey using a unified web-based platform was conducted in forty-four hospitals across the country from 3 to 23 November 2019 to estimate the prevalence of antimicrobial use and healthcare-associated infections among both governmental and private sectors.

RESULTS

All in all, 3657 inpatients in the 44 participating hospitals were surveyed; 51.4 % were on at least one antibiotic at that time. Pneumonia was the most frequently reported hospital-acquired (47 %), followed by intra-abdominal sepsis (10.9 %), upper respiratory tract infections (10.6 %), and urinary tract infections (9.9 %). Ceftriaxone and piperacillin/Tazobactam were the most frequently used antibiotics (13.5 %, 9.6 %). Compliance with guidelines was reported in 70.3 % of prescriptions. Only 11.4 % of patients received a single dose of surgical prophylaxis.

CONCLUSION

Our results on antimicrobial use and hospital-acquired infection prevalence are comparable to other regional and international findings. Local guidelines are needed to reduce the excessive use of Watch and Reserve antibiotics, reduce prolonged antibiotic use after surgery, and decrease hospital-acquired infections.

A comparison of oral bacteriome isolated from periodontal pockets of participants with or without diabetes mellitus in Uganda: a case control study

OBJECTIVE

Diabetes mellitus predisposes patients to increased incidence and severe forms of periodontal disease. Currently, information on the bacterial diversity of patients with diabetes mellitus and periodontitis in Uganda is scanty. This study set out to describe the bacteria associated with periodontitis in patients with diabetes mellitus in Uganda, as part of a larger study describing the association between periodontal disease and diabetes mellitus.

RESULTS

This was a case control involving 45 samples of gingival crevicular fluid collected from participants with periodontitis, the cases being 26 participants with diabetes mellitus and controls 19 participants without diabetes mellitus. Sequencing using the 16s Oxford nanopore long read protocol was followed by a bioinformatics analysis pipeline for alpha and beta diversity indices in the two groups. Multivariate tests were done to determine the differences in the bacterial composition in the two groups. Of the 739 Operational Taxonomic Units and 500 phyla identified, 37.9% (280/739) were from participants with diabetes mellitus. Analysis of beta diversity revealed a dissimilarity between the two study groups (CAP score = 0) with a significant association noted between periodontitis and the subgingival bacteria (P = 0.001). Diabetes mellitus reduced the quantity and altered the composition of the subgingival microbiome in the study participants.

Point Prevalence Survey of Antibiotic Use across 13 Hospitals in Uganda

Standardized monitoring of antibiotic use underpins the effective implementation of antimicrobial stewardship interventions in combatting antimicrobial resistance (AMR). To date, few studies have assessed antibiotic use in hospitals in Uganda to identify gaps that require intervention. This study applied the World Health Organization’s standardized point prevalence survey methodology to assess antibiotic use in 13 public and private not-for-profit hospitals across the country. Data for 1077 patients and 1387 prescriptions were collected between December 2020 and April 2021 and analyzed to understand the characteristics of antibiotic use and the prevalence of the types of antibiotics to assess compliance with Uganda Clinical Guidelines; and classify antibiotics according to the WHO Access, Watch, and Reserve classification. This study found that 74% of patients were on one or more antibiotics. Compliance with Uganda Clinical Guidelines was low (30%); Watch-classified antibiotics were used to a high degree (44% of prescriptions), mainly driven by the wide use of ceftriaxone, which was the most frequently used antibiotic (37% of prescriptions). The results of this study identify key areas for the improvement of antimicrobial stewardship in Uganda and are important benchmarks for future evaluations.
