A cross-sectional study was conducted in Purulia district, West Bengal, India, to assess the skill of 155 frontline workers implementing Integrated Management of Neonatal and Childhood Illness (IMNCI) and the logistic support thereof. The skills of counting respiratory rate, assessing immunization status in both age groups, assessment of breastfeeding in young infants and plotting of weight in a growth chart in case of children aged 2-59 months were acquired by majority of workers. Around two-thirds workers synthesized correct classification and nearly 60% gave appropriate management of at least one subgroup. In 30-40% cases, carers received feeding advices. Around 50% casesheets were complete and timely report submission rate was nearly 70%. Necessary equipments were available with majority of workers except the utensils for preparation of ORS. The supply of essential drugs varied from 33.5 to 71.6%. These findings suggest that IMNCI program offered a scope for capacity-building and infrastructure strengthening of the health system.
