Infants referred for any reason from another health facility or those needing immediate cardiopulmonary resuscitation were excluded.Outcome measures Infants were evaluated for distribution (head, trunk, distal extremities) and degree (mild, moderate, severe) of jaundice by PHWs and physicians. Serum bilirubin level was determined for infants with jaundice, and analyses of sensitivity and specificity of visual estimations of jaundice used bilirubin thresholds of \>260 {\textmu}mol/L (need for phototherapy) and \>340 {\textmu}mol/L (need for emergency intervention in at-risk and preterm babies).Results 1241 (47.0\%) neonates had jaundice. High sensitivity for detecting neonates with serum bilirubin \>340 {\textmu}mol/L was found for {\textquoteleft}any jaundice of the distal extremities (palms or soles) OR deep jaundice of the trunk or head{\textquoteright} for both PHWs (89\%{\textendash}100\%) and physicians (81\%{\textendash}100\%) across study sites; specificity was more variable. {\textquoteleft}Any jaundice of the distal extremities{\textquoteright} identified by PHWs and physicians had sensitivity of 71\%{\textendash}100\% and specificity of 55\%{\textendash}95\%, excluding La Paz. For the bilirubin threshold \>260 {\textmu}mol/L, {\textquoteleft}any jaundice of the distal extremities OR deep jaundice of the trunk or head{\textquoteright} had the highest sensitivity across sites (PHWs: 58\%{\textendash}93\%, physicians: 55\%{\textendash}98\%).Conclusions In settings where serum bilirubin cannot be measured, neonates with any jaundice on the distal extremities should be referred to a hospital for evaluation and management, where delays in serum bilirubin measurement and appropriate treatment are anticipated following referral, the higher sensitivity sign, any jaundice on the distal extremities or deep jaundice of the trunk or head, may be preferred.Data are available upon reasonable request.
