Insights
Rational use of medicines (RUM) in children is challenging. A study found that passive interventions like training and formulary distribution were ineffective in improving RUM in Sri Lankan children.
Area of Science:
- Pediatric pharmacotherapy
- Health services research
Background:
- Rational use of medicines (RUM) in pediatric populations presents unique challenges compared to adults.
- Limited data exists on RUM in children within Sri Lanka.
Purpose of the Study:
- To evaluate the current status of RUM in children in Sri Lanka.
- To determine the effectiveness of a combined intervention in enhancing RUM in pediatric patients.
Main Methods:
- A non-randomized controlled before-and-after study was conducted in two pediatric hospital units.
- An intervention group received one-time training and a pediatric formulary, while a control group did not.
- Fourteen indicators, including WHO guidelines and investigator-developed metrics, were used to assess medicine use at baseline, three months, and one year post-intervention.
Main Results:
- At baseline, 9 out of 14 indicators were satisfactory in both units.
- Post-intervention, only three indicators showed favorable changes: recorded prescription reasons, treatment without regular medicines, and appropriate paracetamol dosing.
- The use of abbreviations in prescriptions undesirably increased in the intervention unit compared to the control unit.
Conclusions:
- Passive interventions, such as training and formulary provision, appear insufficient to improve RUM in children.
- General medicine use indicators may not adequately capture the specific complexities of pediatric pharmacotherapy.
Introduction:
Challenges in rational use of medicines (RUM) in children are different from that of adults. In Sri Lanka, data on RUM in children are limited.
Objective:
To assess the current status and to investigate effectiveness of an intervention in improving RUM in children.
Methods:
Non-randomised controlled before and after study design was employed. Study settings were one paediatric unit in two Teaching Hospitals one for intervention (IU) and the other as a control (CU) unit. After assessing the current status in both units, a combined intervention (one-time training and distribution of a paediatric formulary) was offered to IU and medicine use was re-assessed in both units three months and one year after intervention. Fourteen indicators (7 WHO and 7 developed by investigators) were employed in the assessment. Any improvement was analysed using percentage changes, Chi-square or t tests as appropriate.
Results:
A total of 1134 charts, 735 (3197 medicines) in IU and 399 (1539 medicines) in CU were subjected to analysis. At base level, of the 14 indicators, 9 were assessed satisfactory in both units. Four could not be assessed without knowing the clinical setting. The remaining indicator, reason for prescribing was recorded for 48% and 76% of medicines respectively in IU and CU. After intervention, only three indicators, medicines that had the reason for prescription recorded in the patient records, children treated without regular medicines, and children received the recommended doses of paracetamol, showed favourable changes in three months and one year. Percentage of medicines written in abbreviation showed an undesirable increase in IU (6.9, 16.2, 29.6) which was higher than what was observed in CU (3.2, 13.5, 18.4).
Conclusions:
Passive interventions appear to be ineffective in improving RUM in children. In addition, general medicine use indicators seem to be insensitive to capture the true challenges in paediatric pharmacotherapy.

For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
