Objectives: Community - Acquired Pneumonia (CAP) is the leading cause of morbidity and mortality of children in developing country that overburden national health cost. Mean platelet volume has been known as inflammatory biomarker in many infectious disease including pneumonia. This study aimed to predict length of stay in children hospitalized with CAP using MPV value. Methods: This was a prospective study including patients in pediatric departments in Saiful Anwar General Hospital Malang between January and Juny 2017. Forty five children aged 2 – 96 months hospitalized with pneumonia were enrolled. Blood samples were examined for complete blood count and MPV. Association between MPV value, sex and age with hospital length of stay were determined using logistic regression. Statistical analysis was performed using SPSS 24.0 computer software. Results: A total 45 patients were diagnosed with CAP during the study period. Twenty two (48%) subjects were male and twenty three (52%) were girls. MPV (cut-off point 9.15 fL) was not associated with LOS of > 7 days (OR 3.28, 95% CI 0.833- 12.979) and OR 0.027 (p=0.000 95% CI 0.005 – 0.155) after adjusted with aged and sex. Conclusion: The MPV value is poor predictor for length of stay in patients with hospitalized community – acquired pneumonia.
