Manifestasi klinis demam berdarah dengue (DBD) masih menjadi permasalahan dalam kesehatan masyarakat di Indonesia. Berdasarkan derajat keparahan DBD menurut kritera WHO 2011 terbagi atas DBD derajat I, DBD derajat II, DBD derajat III, dan DBD derajat IV. Di Indonesia insiden DBD meningkat walaupun angka kematiannya menurun, untuk itu penelitian ini bertujuan meneliti faktor-faktor yang berhubungan dengan keparahan DBD, dimana DBD derajat II, III, dan IV dikategorikan sebagai DBD parah. Penelitian cross-sectional yang menggunakan data sekunder dari studi etiologi demam akut dari delapan rumah sakit di Indonesia, didapatkan proporsi keparahan DBD sebesar 43,3%. Faktor-faktor yang berhubungan dengan keparahan DBD didapatkan faktor jenis serotipe virus DENV-2 (OR = 3,06 95%CI 1,43-6,55), DENV-3 (OR = 2,62 95% CI 1,33-5,15), faktor lama demam (OR = 1,91 95%CI 1,09-3,35), dan faktor jumlah leukosit (OR = 1,79 95%CI 1,02-3,16). Skoring didapatkan sebesar 67% kemampuan untuk memprediksi keparahan. Dengue hemorrhagic fever (DHF) as a clinical manifestasion of dengue infection remains a public health problem in Indonesia. According to WHO, DHF severity grade was divided into DHF I, DHF II, DHF III and DHF IV. In Indonesia, the incidence of DHF increased eventhough the mortality rate decreased. Therefore, the study aims to examine prognostic factors related to the severity of DHF, with the category of severe DHF is including DHF II, DHF III and DHF IV. This cross-sectional study using secondary data from the Acute Febrile Illness Etiology Study of eight Hospitals in Indonesia. The result as follow, the proportion of severe DHF category is 43.3%, the prognostic factors associated with DHF severity are DENV serotype (DENV-2, OR = 3.06 95% CI 1.43 - 6.55; DENV-3, OR = 2.62 95% CI 1.33 - 5.15), day of illness (OR = 1.91 95% CI 1.09 - 3.35), and leucocyte count (OR = 1.79 95% CI 1.02 - 3.16). The scoring with contributing of DENV serotype, day of illness, and leucocyte count as prognostic factors, has only 67% ability to predict DHF severity. |
