Emergency Department Initiated Versus Trauma Team Initiated Massive Transfusion Protocols After Injury: A Review of Activation, Time to Transfusion, and Clinical Outcomes

Background. Atopic dermatitis, psoriasis, scabies, and tinea share clinical features and require different treatment. We examined how often diagnoses made by primary care and emergency physicians agreed with dermatologist assessments and which conditions accounted for disagreement. Methods. We reviewed original comparative studies published through 31 May 2026. We extracted disease-specific sensitivity, positive predictive value, agreement, and documented diagnostic errors. Differences in patient selection, denominators, and reference assessments supported narrative synthesis. Results. We included twelve original studies. In a Spanish referral cohort, sensitivity was 85% for atopic dermatitis, 88.8% for psoriasis, and 25% for scabies. In North Indian primary care, the physician recognized two of fourteen dermatologist-diagnosed psoriasis cases and sixteen of eighteen scabies cases. Eleven eczema cases received a scabies diagnosis. In Bahrain, clinicians agreed on six of eight psoriasis cases, ten of fourteen scabies cases, and two of six tinea cases. Maritime physicians recognized two of twelve dermatologist-diagnosed tinea cases. French pediatricians agreed with a dermatologist on 73% of atopic dermatitis diagnoses across emergency and community settings. Emergency studies generally reported agreement across mixed skin disorders. Conclusion. Diagnostic performance varied between conditions and clinical settings. Scabies was both missed and overdiagnosed, while psoriasis recognition differed markedly between cohorts. Tinea estimates were based on small samples.
