Compliance of WHO Guideline on Dengue Management among Indian Patients: An Interventional Quality Improvement Study

Dengue fever management is guided by WHO guideline, the recent one being 2009; however, compliance to the guideline is difficult to assess and in India there is no data on it. The present study, a longitudinal pre-post interventional quality improvement study, was done to determine the compliance to the guideline on dengue patients before and after resident physicians' training during two peak seasons and their impact on survival.

This study was conducted in a tertiary health care centre in North India over 18 months. Data of hospitalized patients who admitted with dengue fever diagnosis in a peak season was collected in the form of quality indicators as described by the WHO-2009 guideline on dengue. Resident physicians were then given appropriate training about the guideline during the off season. Data of new dengue patients in next peak season after resident training was collected and compared with the baseline by standard statistical tests.

The post-intervention compliances of all components increased (total mean score by giving one point to each of the quality indicators reached 7.9 from 6.4). The compliance to individual indicator also increased: the admission criteria (baseline, 44% to post-intervention, 52%, p = 0.37), classification criteria (91.7% to 96%, p = 0.33), correct staging/triage (42.9% to 86%, p <0.001), vitals monitoring (85.7% to 92%, p = 0.28), correct usage of bolus fluids (34.3% to 69.5%, p <0.001), crystalloid as choice of fluid (100% in both groups), proper fluid titration (26.2% to 56%, p <0.001), hematocrit monitoring (95.2% to 98%, p = 0.42), platelet transfusion when indicated (65.5% to 58%, p = 0.39), antibiotic use when required (61.5% to 80%, p = 0.03), and discharge criteria (100% in both groups). The mortality decreased from 7.1% (baseline) to zero (post-intervention). The median duration of hospital stay also reduced by 1 day.

The study affirms that the compliance to WHO guideline on dengue management in India can be further improved by regular physician training on the guideline. Simultaneously, this educational intervention not only improves patient outcomes but also direct proper resource utilization especially platelet transfusion and antibiotic use. Furthermore, every hospital/institute should have an internal quality improvement program like this to improve the management of dengue patients. Future studies are needed to understand various barriers to 100% implementation of the guideline.
