Reconstitution of oral antibiotic suspensions for paediatric use in households: a cross-sectional study among caregivers of 3-5-year-old children from a selected district, Sri Lanka.

Introduction: Reconstitution of oral pediatric antibiotic suspension by primary caregivers plays an essential role in determining the overall health outcome of the child. Incorrect reconstitution techniques could lead to underdosing, overdosing, or introduction of infection. Underdosing could lead to non-resolving infection and antimicrobial resistance.

Objectives: To assess the practice and associated factors on reconstitution of oral pediatric antibiotic suspensions (OPAS) among primary caregivers of 3-5-year-old children in a selected district in Sri Lanka.

Methods: A cross-sectional study was carried out among 835 primary caregivers selected using two-stage cluster sampling at field clinics to assess practices for the reconstitution of OPAS. A live demonstration of the reconstitution of the OPAS was assessed by a checklist. Associated factors with caregiver practices on reconstitution were assessed using Chi-square with the statistical significance level set at 0.05.

Results: A total of 820 respondents were recruited and completed the study (response rate = 98.2%). Overall, 56.0% displayed good performance in the demonstration of reconstitution of oral pediatric antibiotic suspension. Poorest performances were observed in shaking the bottle to loosen the powder (Correct: 53.7%), topping up the bottle with water up to the marked line (Correct: 58.0%), and filling the water below the marked line in the bottle (Correct: 59.0%). Caregivers in urban areas compared to rural and estate regions (45.6% vs. 22.7% and 26.5% respectively) and caregivers aged 35 years or above compared to less than 35 years age group (31.5% vs. 22.5%) performed the reconstitution of OPAS poorly. Parental factors, namely age, gender, level of education, and geographical region (urban/rural/estate) were significantly associated with the performance in reconstituting the oral paediatric antibiotic suspension (p = 0.002, p < 0.001, p < 0.001, and p < 0.001 respectively). Factors related to the child, specifically whether they attend preschool and whether they have an older sibling, were found to have a significant association with the correct execution of the reconstitution of OPAS (p = 0.017, and p = 0.030 respectively).

Conclusions And Recommendations: A significant number of primary caregivers displayed poor practice in key steps during the reconstitution of OPAS, which could have a negative impact on the health of the child. Targeted place-based behavioural change health programs with the use of infographic leaflets/ posters may correct the practices of caregivers.
