An umbrella search of systematic reviews was conducted in January 2024.<\/jats:p>\n <\/jats:sec>\n \n Study Selection<\/jats:title>\n Included studies reported data on 24 infant clinical signs informed by current World Health Organization (WHO) Integrated Management of Childhood Illness (IMCI) and hospital-based algorithms for the care of sick young infants reporting odds ratios (OR), risk ratios, or sensitivity and specificity.<\/jats:p>\n <\/jats:sec>\n \n Data Extraction and Synthesis<\/jats:title>\n Data were extracted independently by 2 reviewers. Quality assessment used the Newcastle-Ottawa, Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2), and Quality Assessment of Prognostic Accuracy Studies (QUAPAS) scales. OR data were pooled using random-effects models. Data analysis was performed from July to September 2025.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n OR of all-cause mortality, culture-confirmed sepsis, or clinical sepsis (with access to laboratory investigations).<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Of 7641 studies, 52 studies with 140\u202f885 participants were included. A total of 16 clinical signs were significantly associated with mortality, 11 with culture-confirmed sepsis, and 13 with clinical sepsis. For mortality, the 5 strongest associations were weak, abnormal, or absent cry (OR, 20.48; 95% CI, 6.59-63.67); not able to feed at all (OR, 18.32; 95% CI, 6.00-55.97); not feeding well (OR, 13.39; 95% CI, 6.97-25.72); drowsiness or unconsciousness (OR, 12.46; 95% CI, 6.06-25.62); and prolonged capillary refill (OR, 12.06; 95% CI, 2.77-52.53). The top 5 signs associated with culture-confirmed sepsis were not feeding well (OR, 4.52; 95% CI, 1.10-18.59); prolonged capillary refill (OR, 3.59; 95% CI, 2.05-6.28); lethargy (OR, 3.44; 95% CI, 1.89-6.26); drowsiness or unconsciousness (OR, 3.07; 95% CI, 2.01-4.68); and feeding intolerance (OR, 2.95; 95% CI, 1.67-5.21).<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n All current WHO IMCI clinical signs were significantly associated with mortality or culture-confirmed sepsis. Several signs not in IMCI were identified that may improve identification of life-threatening illness in young infants in resource-limited settings where clinical sign algorithms are the primary diagnostic tool.<\/jats:p>\n <\/jats:sec>","DOI":"10.1001\/jamapediatrics.2025.5967","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T16:00:21Z","timestamp":1770048021000},"page":"384","source":"Crossref","is-referenced-by-count":6,"title":["Clinical Signs Associated With Mortality and Sepsis in Young Infants"],"prefix":"10.1001","volume":"180","author":[{"given":"Sophie","family":"Driker","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Division of Newborn Medicine, Brigham and Women\u2019s Hospital, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sitarah","family":"Mathias","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Boston Children\u2019s Hospital, Boston, Massachusetts"},{"name":"Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alastair","family":"Fung","sequence":"additional","affiliation":[{"name":"Division of Paediatric Medicine, The Hospital for Sick Children, University of Toronto, Toronto, Ontario, Canada"},{"name":"Centre for Global Child Health, The Hospital for Sick Children, Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suci Ardini","family":"Widyaningsih","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Division of Newborn Medicine, Brigham and Women\u2019s Hospital, Boston, Massachusetts"},{"name":"Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naomi","family":"Schmeck","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Division of Newborn Medicine, Brigham and Women\u2019s Hospital, Boston, Massachusetts"},{"name":"Harvard T.H.
