Quantifying antimicrobial access and practices for paediatric diarrheal disease in an urban community setting in Southeast Asia
AbstractAntimicrobial-resistant infections are increasing across Asia. Aiming to evaluate antimicrobial access and practices in Ho Chi Minh City (HCMC) of Vietnam, we mapped pharmacy locations and used a simulated client method to calculate antimicrobial sales for paediatric diarrheal disease. We additionally evaluated healthcare choices for parents and caregivers when their children experienced diarrhoea. District 8 (population 396,175) of HCMC had 301 pharmacies (one for every 1,316 people), with a density of 15.8 pharmacies/km2. A wide range of different treatments (n=57) were sold for paediatric diarrheal disease, with 8% (3/37) and 22% (8/37) of the sampled pharmacies selling antimicrobials for watery and mucoid diarrhoea, respectively. Despite the apparent abundance of pharmacies, the majority of caregivers chose to take their child to a specialized hospital, with 81% (319/396) and 88% (347/396) of responders selecting this as their first, second, or third choice for watery and mucoid diarrhoea, respectively. Lastly, by combining denominators derived from caregiver interviews and diarrheal incidence figures, we calculated that 16% (2,359/14,427) of watery or mucoid diarrhoea episodes of the District 8 population aged 1 to <5 years would receive an antimicrobial for diarrhoea annually, but antimicrobial prescribing was almost ten times greater in hospitals than in the community. Our novel mixed-methods approach found that, whilst antimicrobials are commonly available for paediatric diarrhoea in the community of HCMC, usage is greater in hospitals. The observed non-standardized approach to diarrheal treatments is indicative of poor recommendations. We advocate better guidelines, training and dissemination of information regarding antimicrobials and their use in this location.
