The role of the systemic inflammatory index in determining the length of hospital stay in patients with hyperemesis gravidarum.

ABSTRACT

OBJECTIVE: In this study, we aimed to investigate the role of peripheral blood parameters and the systemic inflammatory index (SII) in the diagnosis of hyperemesis gravidarum (HG) and whether they have a predictive value in determining the length of hospital stay and the risk of rehospitalization in HG cases. MATERIALS AND METHODS: In the retrospective study, pregnant women who were hospitalized due to HG (n = 112) and pregnant women who were completely healthy (n = 112) were matched for gestational age. Peripheral blood inflammation parameters of the entire study group were evaluated. The length of hospital stay and rehospitalization rate for HG cases were recorded. A total of 224 patients, 112 (50%) in the control group and 112 (50%) in the HG group were included in the study. There was a positive correlation between increased ketonuria and length of hospitalization, peripheric blood parameters, and SII. The degree of ketonuria was found to be statistically insignificant in determining the risk of rehospitalization (p = 0.927). About 28.57% (n = 32) of all HG cases were readmitted to the hospital. When the length of hospital stay was considered, SII was found to be statistically significant in hospitalizations lasting more than 2 days (p = 0.001), but not in rehospitalizations (p = 0.3). CONCLUSION: SII is significant in diagnosing and determining hospitalization of HG. It is sufficient to determine the length of hospital stay but not rehospitalization risk, which is an indicator of disease severity.
