CORRELATION OF LYMPHOCYTE-MONOCYTE RATIO AND MORTALITY OF COVID-19 INTENSIVE CARE UNIT PATIENTS: PRELIMINARY STUDY

Abstract

Background: The world faces a pandemic caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCov-2). Because of the limitations as a developing country, Indonesia needs to do its activities efficiently in time,
money, and human resource. This research aims to accurately determine a concrete mortality predictor to predict
the patients' mortality. One of the mortality predictors is the lymphocyte-monocyte ratio (LMR).
Method: This research is observational analytic research using a cross-sectional study method. Data obtained
from the Medical Record & Casemix Room of RSUD Raden Mattaher.
Results: Out of 115 samples, most patients were male (65 patients). The patients' age group was mainly younger
than 65 (79%). The most common comorbidity was diabetes mellitus (43 patients). The correlation between LMR
and mortality rate to be weak with the following results: Pearson coefficient(p=0.045), gamma coefficient (P=0.325),
Somers' D test (P=0.167), odds ratio (1.833), AUC (58%), specificity (58%), sensitivity (56%), and intersection point
(1,79).
Conclusions: There is a weak correlation between LMR and the mortality rate of COVID-19 patients in RSUD
Raden Mattaher.
Keywords: Characteristics of COVID-19 patients, comorbidity of COVID-19 patients, LMR (Lymphocyte-monocyte
ratio), a mortality rate of COVID-19 patients.
