Introduction And Core Philosophy
- Comprehensive Under-5 Screening Program (CUSP) is a structured, multi-dimensional clinical framework designed for early identification of developmental delays, nutritional deficiencies, sensory impairments, and congenital or acquired disorders in children from birth to 60 months.
- Operationalized as the expanded Rashtriya Bal Swasthya Karyakram (RBSK) 2.0 under the Ministry of Health and Family Welfare (MoHFW) in May 2026.
- The first five years represent a critical window of maximal neuroplasticity; CUSP shifts child healthcare from a reactive treatment model to a proactive, preventive strategy.
Recent Enhancements In RBSK 2.0
- Expanded Scope: Extends the original RBSK framework of the "4 Ds" (Defects at birth, Diseases, Deficiencies, Developmental delays) to screen for over 32 common conditions.
- New Integrations: Mandates screening for emerging non-communicable diseases (NCDs) like diabetes, hypertension, and obesity, alongside early mental health and behavioral red flags.
- Digital Linkage: Integrates with the U-WIN portal to track developmental outcomes, minimize dropout rates in follow-up, and ensure seamless linkage to tertiary care.
Core Pillars And Dimensions Of Screening
| Screening Domain | Clinical Metrics And Standardized Tools |
|---|---|
| Anthropometric & Nutritional | - Tracks Weight-for-Age, Height/Length-for-Age, and Head Circumference on WHO Growth Charts.- Severe Acute Malnutrition (SAM) screening using MUAC < 11.5 cm (6–59 months).- Clinical screening for nutritional anemia, Vitamin D (rickets), and Vitamin A (Bitot's spots) deficiencies. |
| Neurodevelopmental | - Longitudinal surveillance at 2, 4, 6, 9, 12, 18, 24, 36, 48, and 60 months.- Utilizes standardized tools like the Trivandrum Developmental Screening Chart (TDSC) and Denver Developmental Screening Test (DDST-II).- Mandates M-CHAT-R/F at 18 and 24 months to detect Autism Spectrum Disorder (ASD). |
| Sensory (Hearing & Vision) | - Universal Newborn Hearing Screening (UNHS) using TEOAE and AABR.- Infant vision screening via Brückner test (red reflex) for cataracts or retinoblastoma.- Visual acuity testing in toddlers (3–5 years) using Snellen E-charts or Lea Symbols. |
| Congenital & Systemic | - Clinical screening for developmental dysplasia of the hip (Barlow/Ortolani maneuvers), clubfoot, and undescended testes.- Critical congenital heart disease (CCHD) screening via routine pulse oximetry.- Targeted heel-prick screening for congenital hypothyroidism, G6PD deficiency, and hemoglobinopathies. |
Operational Implementation Framework
- Tier 1 (Community Level): Frontline community health workers (ASHA, Anganwadi workers, and mobile health teams) perform basic tracking of physical growth, visible birth defects, and gross milestone delays at homes, schools, and Anganwadi centers.
- Tier 2 (Primary Health Facility): Medical officers or primary pediatricians review referred children utilizing formal screening toolkits and parental questionnaires.
- Tier 3 (Specialized Early Intervention): Multidisciplinary teams (developmental pediatricians, neurologists, speech therapists) at District Early Intervention Centers (DEICs) conduct definitive diagnostics and initiate customized, free early intervention plans.
Society Guidelines
- Indian Academy of Pediatrics (IAP 2025–2026): Strongly endorses CUSP integration into well-child visits.
- Recommends developmental surveillance at every visit and formal screening at 9, 18, 24, 30, and 36 months.
