Factors Affecting Mortality in Critical Patients Admitted to Intensive Care Unit Due to Coronavirus Disease 2019

Acute Physiology and Chronic Health Evaluation II Score

The score can help in the assessment of patients to determine the level \& degree of diagnostic \& therapeutic intervention. Interpretation of APACHE II: minimum 0 and maximum 71; increasing score is associated with an increasing risk of hospital death.

Time frame: APACHE II score on the first admission of ICU

Sequential Organ Failure Assessment Score

The Sequential Organ Failure Assessment (SOFA) score is a scoring system that assesses the performance of several organ systems in the body (neurologic, blood, liver, kidney, and blood pressure/hemodynamics) and assigns a score based on the data obtained in each category. The SOFA score is made of 6 variables, each representing an organ system. Each organ system is assigned a point value from 0 (normal) to 4 (high degree of dysfunction/failure). Score ranges from 0 (best) to 24 (worst) points.

Time frame: SOFA score on the first admission of ICU

Kidney Disease: Improving Global Outcomes Scores

It is a system used to determine the severity of kidney failure. It is a classification consisting of four stages: 0-1-2-3. It indicates that the level of failure worsens as the stage increases.

Time frame: When the patients were admitted to ICU for the first time.
