ABSTRACT
Aim: In this study, we aimed tto compare the 30-day mortality prediction abilities of the acute physiology and chronic health evaluation II (APACHE II), CURB-65, pneumonia severity index (PSI), A-DROP, Infectious Diseases Society of America/American Thoracic Society severity criteria, and I-ROAD scores in patients aged over 80 years admitted to the intensive care unit with COVID-19 pneumonia. Material(s) and Method(s): The study was conducted with a single-center retrospective observational design and included patients aged 80 years and older who were admitted to the intensive care unit due to COVID-19 pneumonia between March 2020 and August 2021. Patient demographic data, imaging findings, blood test results, discharge status, length of stay in the intensive care unit, duration of mechanical ventilation, inotropic drug administration status, presence/ absence of mortality and vital signs at the time of admission were obtained from the hospital automation system. Then, the above-mentioned scores were calculated and compared statistically. Result(s): The study was completed with 119 patients, 60 (50.4%) women and 59 (49.6%) men. The mean age of all patients was 84 (80-98) years, and the mortality rate was 84.03% (n=100). Among the scoring systems, I-ROAD had the highest area under the curve (AUC) value (0.703), APACHE II had the highest specificity (94%), and A-DROP had the highest sensitivity (64%). Discussion(s): According to our results, the I-ROAD scoring system is an effective tool that can be used in the prediction of mortality related to COVID-19 pneumonia among intensive care patients aged >=80.Copyright © 2023, Derman Medical Publishing.

ABSTRACT
Introduction: Numerous clinical and laboratory scores that include C-reactive protein (CRP), D-dimer, ferritin, lactate dehydrogenase (LDH), interleukin 6 (IL-6), procalcitonin (PCT), blood urea nitrogen (BUN), creatinine levels and oxygenation (PaO2 and SaO2) have been used for the prognosis of COVID-19. In addition, composite scores have been developed for the assessment of general state and risk in community-acquired pneumonia (CAP) that may be applied for COVID-19 as well. In this study, we assessed severity and potential prognostic risk factors for unfavorable outcome among hospitalized COVID-19 patients. We also applied the A-DROP general scoring system used in CAP to COVID-19. Patients and methods: Altogether 233 patients admitted to our center with COVID-19 were included in the study. Clinical status, several laboratory biomarkers described above, indicators of oxygenation were determined at hospital admission. We also applied the A-DROP composite scoring system that includes Age (≥ 70 years in males and ≥ 75 years in females), Dehydration (BUN ≥ 7.5 mmol/l), Respiratory failure (SaO2 ≤ 90% or PaO2 ≤ 60 mmHg), Orientation disturbance (confusion) and low blood Pressure (systolic BP ≤ 90 mmHg) to COVID-19. Results: At the time of admission, most patients had elevated CRP, LDH, ferritin, D-dimer, and IL-6 levels indicating multisystemic inflammatory syndrome (MIS). Altogether 49 patients (21.2%) required admission to ICU, 46 (19.7%) needed ventilation and 40 patients (17.2%) died. In the binary analysis, admission to ICU, the need for ventilation and death were all significantly associated with the duration of hospitalization, history of hypertension or obesity, confusion/dizziness, as well as higher absolute leukocyte and neutrophil and lower lymphocyte counts, elevated CRP, PCT, LDH, ferritin, IL-6, BUN, and creatinine levels, low PaO2 and SaO2 and higher A-DROP score at the time of admission (p < 0.05). Conclusion: Numerous laboratory biomarkers in addition to obesity, dizziness at the time of admission and the history of hypertension may predict the need for ICU admission and ventilation, as well as mortality in COVID-19. Moreover, A-DROP may be a suitable scoring system for the assessment of general health and disease outcome in COVID-19.
