OBJECTIVE: In this study, we aimed to assess the predictive value of Intermountain Risk Score (IMRS) in intensive care unit (ICU) patients with COVID-19.

PATIENTS AND METHODS: Our retrospective study included the data of 194 patients who were admitted to the COVID-19 ICU of a tertiary care center. COVID-19 diagnoses were made by a positive result from a real-time reverse-transcriptase (RT) polymerase chain reaction (PCR) assay of nasal and pharyngeal swab specimens. Patients who had negative RT-PCR results or who were not admitted to ICU and patients under 18 years old were excluded from the study. Complete blood count, biochemistry panel, and blood gas analysis results were gathered and compiled.

RESULTS: 194 ICU patients with COVID-19 (PCR positive) were included in the study. The patients were divided into two groups according to IMRS (if IMRS was <15 in women and <17 in men, patients were included in the non-high-risk group, while patients with IMRS ≥15 in women and ≥17 in men were defined as a high-risk group). Multivariate regression analysis was performed to predict in-hospital mortality. The IMRS [OR: 1.17 (1.08-1.27) p<0.001)] was found to predict in-hospital mortality.

CONCLUSIONS: In this study, we showed that the IMRS score at admission can predict in-hospital mortality in intensive care unit patients with a diagnosis of COVID-19.
