Integrated Management of Neonatal and Childhood Illnesses (IMNCI) guidelines provide a standardized process for effectively managing child health. The guidelines address the most common pediatric problems for children under 5 through (1) assessing and classifying illnesses, (2) identifying appropriate treatments, (3) treating children and counseling caretakers, and (4) providing follow-up care. An integrated approach has advantages like speeding urgent treatment, prompt referral for serious conditions, involving parents in home care, and cost-effectively addressing multiple diseases through immunization, nutrition, and breastfeeding practices.
