Characterization of Thrombocytopenia in Pediatric Patients in Noncritical Hospital Setting: An Institutional Review From Pakistan.

Pediatric thrombocytopenia is frequently observed in critical care and oncology settings with an increased risk of bleeding and platelet transfusions. However, little is known about low platelets in childhood during seasonal influence. This study aimed to evaluate the frequency and severity of pediatric thrombocytopenia in the postflood period. The patients 1 to 18 years of age with thrombocytopenia (platelet count <150×109/L) were studied from August to December 2022 after institutional ethical approval (ERC-Path-2022-8044-23395). Data was collected from electronic health records and laboratory information systems. Of 2318 admitted patients, 192 (8.3%) including 128 males and 64 females had thrombocytopenia. The median (IQR) age was 12 (8 to 15) years. Mild, moderate, and severe thrombocytopenia were seen in 109 (56.8%), 76 (39.5%), and 7 (3.6%) patients, respectively. Concomitant leucopenia was observed in 77 of 192 patients (40.1%). Infection was the predominant cause of low platelets (N=175 or 91.1%). Only 15 patients (7.8%) had grade 1/2 bleeding. Overall, 176 patients (92%) were discharged in stable conditions and no mortality was observed. The frequency of pediatric thrombocytopenia in the noncritical and nononcological care settings was <10% and mostly observed in association with underlying infections. The frequency of bleeding manifestation and platelet transfusions was minimal in this group.
