ABSTRACT
Fever accounts for around 15% of emergency visits in elderly age group and around 5% in adults. The spectrum of etiologies ranges from non-infectious to infectious etiologies. There are very few studies done in the past highlighting the approach of patients with acute febrile illness without any localizing signs and symptoms. OBJECTIVES: The aim of the study was to formulate a targeted approach for evaluation and treatment of patients with acute undifferentiated febrile illness without evidence of localizing symptoms and signs. The secondary objective was to study the etiology and final outcome of patients with acute undifferentiated febrile illness. MATERIALS AND METHODS: A protocol was devised for patients aged more than 18 years, who presented in emergency department with complaints of fever without localizing symptoms or signs of sepsis over a period of 6 months from April 2018 to September 2018. Patient's data were collected retrospectively from the hospital record section. RESULTS: A total of 212 patients of undifferentiated acute febrile illness were enrolled in the study. Maximum number of patients [n = 69 (32.5%)], presented on second day of illness. All the patients presenting within 1 or 2 days of fever experienced defervescence. Out of these 69 patients, 35 (36.4%) were investigated of which in 29 (82.2%) investigations were not found to be useful; 75 (78.1%) patients with 1 or 2 days history of fever improved without investigations. Surprisingly, 54 patients (72%) with 1 or 2 days' history of acute febrile illness experienced defervescence without the need of antibiotics. CONCLUSION: There is an urgent need to devise a standardized protocol for diagnosis and treatment of patients with acute undifferentiated febrile illness in order to avoid unnecessary investigations and antimicrobial use.
