Background and Objectives: Dengue is an acute self-limited systemic viral infection caused by the dengue virus of the family Flaviviridae. The incidence of dengue fever has been increasing for the past few years and dengue has become a global problem. The current data required for further improving the treatment policies are scanty. Our study aims to capture the demographic and clinical characteristics of the patients enrolled in the study, to see any correlation between thrombocytopenia and bleeding tendencies and other transfusion-related parameters. Methods: The study is a prospective cohort study. All seropositive dengue cases were included in the study. A format was prepared for documenting the demographic data, history, clinical characteristics, spectrum of the disease, the laboratory details of the patient (platelet count, prothrombin time, activated partial thromboplastin time, Hematocrit, and indication). All the transfusion requirement data were collected from the blood center registers. Overall mortality in the study group, number of hospital readmissions, and episodes of exacerbation of symptoms was recorded separately. Results: A total of 270 cases were included in the audit who fulfilled the inclusion and exclusion criteria. The median age of the patient pool was 27 (4–66 years range). Twenty-six percent of the cases developed hemorrhages. Eighty-four single-donor platelets (SDPs) and 340 random-donor platelets (RDPs) were used. A mean of 270 ml of products was transfused per patient. The mortality rate was 0.8%. The mean duration of hospitalization was 1 week. In 72% of cases, platelet count was restored in single-unit transfusion. Ninety-nine percent of the product utilization were within the guidelines recommended. Conclusion: A good monthly audit of blood product utilization is a good guide for treatment. Quality control and rational use of SDPs and RDPs are important in sick and thrombocytopenic patients resulting in better clinical outcomes.
