Summary Background Antimicrobial resistance is increasingly prevalent worldwide. The inappropriate use of antimicrobials, including in the hospital setting, is considered a major driver of antimicrobial resistance. Aim To inform improvements in antimicrobial stewardship, we undertook point prevalence surveys of antimicrobial prescribing at Yangon Children's Hospital and Yangon General Hospital in Yangon, Myanmar. Methods We conducted our surveys using the Global Point-Prevalence Survey of Antimicrobial Consumption and Resistance (Global-PPS) method. All inpatients who were prescribed an antimicrobial on the day of the survey were included in the analysis. Findings We evaluated a total of 1,980 patients admitted to two hospitals during December 2019. Of these, 1,255 (63.4%) patients were prescribed a total of 2,108 antimicrobials. Among antimicrobials prescribed, 722 (34.3%) were third-generation cephalosporins, the most commonly prescribed antimicrobial class. A total of 940 (44.6%) antimicrobials were prescribed for community-acquired infection, and 724 (34.3%) for surgical prophylaxis. Of 2,108 antimicrobials, 317 (15.0%) were prescribed for gastrointestinal tract prophylaxis, 305 (14.5%) for skin, soft tissue, bone and joint prophylaxis, and 303 (14.4%) for pneumonia treatment. A stop or review date was documented for 350 (16.6%) antimicrobial prescriptions, 673 (31.9%) antimicrobial prescriptions were guideline compliant, and 1,335 (63.3%) antimicrobials were administered via the parenteral route. Of 1,083 antimicrobials prescribed for a therapeutic use, 221 (20.4%) were targeted therapy. Conclusion Our findings underscore the need to update and expand evidence-based guidelines for antimicrobial use, promote the benefits of targeted antimicrobial therapy, and support the implementation of hospital-based antimicrobial stewardship programmes at the hospitals surveyed.

Background Accurate estimates of typhoid disease burden are needed to guide policy decisions, including on vaccine use. Data on the incidence of enteric fever in Myanmar are scarce. We estimated typhoid and paratyphoid fever incidence among adolescents and adults in Yangon, Myanmar, by combining sentinel hospital surveillance with a healthcare utilization survey. Methods We conducted a population-based household health care utilization survey in the Yangon Region 12 March through 5 April 2018. Multipliers derived from this survey were then applied to hospital-based surveillance of Salmonella Typhi and Paratyphi A bloodstream infections from 5 October 2015 through 4 October 2016 at Yangon General Hospital (YGH) to estimate the incidence of typhoid and paratyphoid fevers among person ≥12 years of age. Results A total of 336 households representing 1598 persons were enrolled in the health care utilization survey, and multipliers were derived based on responses to questions about healthcare seeking in the event of febrile illness. Of 671 Yangon residents enrolled over a 1-year period at YGH, we identified 33 (4.9%) with Salmonella Typhi and 9 (1.3%) with Salmonella Paratyphi A bloodstream infection. After applying multipliers, we estimated that the annual incidence of typhoid was 391 per 100 000 persons and paratyphoid was 107 per 100 000 persons. Conclusions Enteric fever incidence is high in Yangon, Myanmar, warranting increased attention on prevention and control, including consideration of typhoid conjugate vaccine use as well as nonvaccine control measures. Research on incidence among infants and children, as well as sources and modes of transmission is needed.
