Care of children with congenital rubella syndrome (CRS) in Indonesia.

Introduction: Congenital rubella syndrome (CRS) is associated with severe birth defects, that lead to disability in later life. Hence, early detection and intervention are needed to prevent permanent disability and mortality in children with CRS. We evaluated the time to diagnosis or correction intervention related to survival rate using survival analysis.

Methodology: A retrospective cohort study was conducted to evaluate the follow-up of CRS-confirmed cases from 2011-2018 at a national referral hospital in Jakarta, Indonesia. Parents of eligible children who registered in the national CRS registry as laboratory-confirmed CRS cases were contacted through phone calls or home visits and interviewed about the current situation of their child's health. We also obtained clinical data from the medical records.

Results: Fifty children, age 4 to 14 years, identified with laboratory-confirmed CRS were included in this study. Half (54%) of these children were female. All were born from mothers with no previous rubella vaccination history. Ophthalmic abnormalities such as congenital cataracts (88%) were the most common birth defect. Multiple congenital abnormalities including congenital heart disease, ocular abnormalities, and auditory defects were identified in 52% of the children. Based on Kaplan-Meier analysis, 50% of children were diagnosed at four months. Ophthalmic corrections such as cataract surgery were performed earlier than heart or auditory correction, with 50% of children undergoing eye correction one month after the diagnosis.

Conclusions: There is a vital need to implement CRS surveillance in Indonesia to know the burden of CRS and reinforce the preventive actions, including vaccination against rubella.
