Abstract

Dengue fever remains a significant public health problem in Indonesia, where hematological parameters are commonly used to assess disease severity and support clinical decision-making. Strengthening early detection through laboratory-based indicators is essential to improve patient outcomes and health system preparedness. This study aimed to analyze the association between platelet count, hematocrit levels, and length of hospital stay among dengue patients treated at Hospital X in Mataram. An observational analytic study with a retrospective design was conducted using secondary data from confirmed dengue cases with complete medical records. Spearman correlation analysis was applied due to non-normal data distribution. The results demonstrated a moderate and statistically significant positive correlation between platelet count and length of hospital stay, while hematocrit levels showed no significant association with hospitalization duration. These findings suggest that length of stay in dengue patients is influenced not only by hematological parameters but also by clinical management practices and contextual healthcare factors. This study highlights the importance of contextual interpretation of routine laboratory findings and supports the integration of hospital-based laboratory surveillance to strengthen preparedness and response to dengue outbreaks.
