Factors associated with delay in diagnosis of Kawasaki disease in India.

A retrospective analysis was carried out to identify factors associated with delay in diagnosis of Kawasaki disease in a tertiary care pediatric hospital setting in Chennai, India. Over a period of 2 years, a total of 37 cases were studied. The cases were divided into Early Diagnosis Group (EDG) and Delayed Diagnosis Group (DDG) with the cut-off for early diagnosis being ten days. A greater proportion of cases in the EDG presented primarily to our institution (P=0.004). In the DDG group greater number of cases had received medical attention from practicing pediatricians prior to referral. There was greater interval in onset of individual symptoms in the DDG group. There was no difference between the two groups with regard to age, gender, total blood counts, CRP, liver enzymes, urine analysis or serum albumin values. Platelet counts were higher in the DDG compared to the EDG (P=0.004).Coronary abnormalities were more common in the DDG (P=0.05). Our findings suggest that children presenting primarily to a tertiary care centre with symptoms of Kawasaki disease are more likely to be associated with early diagnosis and delay in onset of neck swelling or oral lesions may be associated with delayed diagnosis. There is a need for creating more awareness about Kawasaki disease among practicing pediatricians in India.
