Clinical presentation, diagnostic evaluation, treatment and diagnoses of febrile children presenting to the emergency department at Muhimbili national hospital in Dar es Salaam, Tanzania

Abstract

While there are many guidelines for the ED evaluation of febrile children, these are largely derived and validated in high-resource settings. There is limited literature documenting recommended or actual management in resource-limited settings. We describe the presentation, diagnostic evaluation, treatment, and ED diagnoses of febrile children under 5 years old presenting to an urban emergency department in Dar es Salaam. Methods: This was a prospective observational study of children under 5 with fever or reported fever at Muhimbili National Hospital (MNH) ED. Treating physicians prospectively completed a standardized data form. Results: We enrolled 105 children, median age 14 months, with 80% >6 months, and 64% male. Presenting symptoms included poor feeding (47.6%) vomiting (42.9%), cough (34.3), difficulty breathing (28.6%), and diarrhoea (22.9%). 78% had vital sign abnormalities and 82% had abnormal physical examination. Among those undergoing point-of care testing, 11/105 tested (10.5%) had hypoglycaemia, 9/103 (8.7 %) were malaria positive, 17/30 (56.7%) had positive urine dipstick testing, and 5/26 tested (19.2%) were HIV positive. Laboratory-based tests included CBC and chemistry (each performed in 95.2%), VBG (56.2%), CSF (5.7%), blood culture (5.7%), urine culture (10.5%), CSF culture (1.9%), and CXR of chest (25.7%) and abdomen (3.8%). Interventions included antibiotics (70%), antimalarial (12%), IV fluids (54%), and antipyretics (41%). Top ED diagnoses included malaria (24.3%), pneumonia (15.2%), septicaemia (9.5%), urinary tract infections (7.6%), acute watery diarrhoea with dehydration (6.7%), meningitis (4.8%), anaemia (4.8%), skin and soft tissue infections (4.8%), bowel obstructions (3.8%), and pulmonary tuberculosis, sickle cell disease, and hepatitis (2.9% each). Laboratory-based tests were often abnormal; culture results were often unavailable; Conclusion: A wide range of presentations and management were documented. There was a high rate of positive diagnostic test results. Malaria and pneumonia were top diagnoses, but a wide range of infections were diagnosed.
