Extent of disability among paediatric Japanese encephalitis survivors and predictors of poor outcome: a retrospective cohort study in North India

ObjectiveTo determine the Japanese encephalitis (JE)-associated long-term functional and neurological outcomes, the extent of reduced social participation and predictors of poor outcomes among paediatric JE survivors.DesignA retrospective cohort study.SettingLaboratory-confirmed JE-positive paediatric cases (Participants126 patients were included in the study; median age was 7.5 years (range: 1.5–15 years), and 74 (58.73%) were male.Outcome measuresFunctional outcome defined by Liverpool Outcome Score (LOS) dichotomised into poor (LOS=1–2) and good (LOS=3–5) outcome groups compared for demographic, clinical and biochemical parameters for prognostic factors of poor outcomes. Social participation of patients scaled on Child and Adolescent Scale of Participation score 2–5.ResultsAbout 94 of 126 (74.6%) children developed neurological sequelae at different levels of severity. Age-expected social participation was compromised in 90 out of 118 children. In multivariate logistic regression analysis, a combination of parameters, JE unvaccinated status (OR: 61.03, 95% CI (14.10 to 264); pχ2=3.13, p=0.988), and area under the receiver operating characteristic curve was 0.950.ConclusionThis study estimates the burden of JE-presenting post-discharge deaths (15.4%) and disability (63.08%). Those who did not receive JE vaccine, were suffering from malnutrition, had GCS ≤8 at admission and required endotracheal intubation had poorer outcomes.
