Abstract: PURPOSE:To compare scoring systems and their ability to capture short and long-term recovery of paediatric patients with acute encephalitis. To identify clinical predictors of short-term outcomes by correlating functional outcome measures at 1 month post diagnosis of acute encephalitis. METHODS:Patients with encephalitis diagnosed between July 2011 and 2016 based on Granerod’s criteria were studied in this retrospective cohort study. Functional outcome scores on WeeFIM, LOS, GOS-E, mRS and ICF at initial presentation and 1, 3, 6 and 12 months later were compared. RESULTS:WeeFIM and LOS scores both showed maximum change in the first 3 months, reflecting highest recovery in this period. With WeeFIM, the greatest change occurred within the first month following diagnosis. On univariate analysis, seizure frequency in the first month, presence of movement disorder, presence of autonomic dysfunction and lower baseline functional score was associated with poorer WeeFIM scores at 1 month. The latter three variables remained statistically significant on multivariate analysis. CONCLUSION:WeeFIM is a potentially preferred functional outcome assessment tool as it demonstrated greatest recovery within the first month due to a trend of high responsiveness and relatively low ceiling effect. Presence of autonomic dysfunction and movement disorders at diagnosis correlated with poorer outcome at 1 month post diagnosis.
