Results:
Pearson’s correlation coefficient and two-sample t-tests were used to evaluate the 213 patients who had a positive COVID-19 PCR test and were hospitalized in the isolation service of our hospital.
Of the 213, 118 were male (55.3%). The average age was 56 years. The number of patients who died was 26 (12.2%). The average age of the 26 patients who died was 60.9 years and the majority were men (17 males, 9 females). The mortality of men is 14.4%, and the mortality of women is 9.4%.
In CT imaging with a staging of maximum 4 points and minimum 0 points, the mean value resulted in 1.95. The average radiological stage of the dead patients group was reported as 2.56. There was a correlation between the radiological predictor and the outcome status (p-value: 0.002). In other words, the radiological stage seems statistically significant in predicting death.
127 patients (59.6%) had chronic disease (hypertension, diabetes mellitus, congestive heart disease, asthma, chronic obstructive pulmonary disease, or other cardiovascular diseases). Of the 26 deceased patients, 13 had a chronic disease, nine had multiple chronic diseases, and four patients did not have any chronic diseases. As expected, the effect of additional chronic disease on death was significant (p-value: 0.003464).
The number of smokers was 14 (6.5%). Of the 26 patients who died, 3 were smokers and 23 were non-smokers. Male patients were more likely to be smokers (p-value: 0.018151).
However, there was no significant distribution of smoking regarding age (p-value: 0.2585). The effect of smoking on radiological staging could not be demonstrated (p-value: 0.368121). We did not see any significant effect on smoking mortality (p-value: 0.2777). There was also no significant effect on discharge time (p-value: 0.2496).
The average discharge time was 13.8 days. Before starting the study, we expected those with high radiological staging to have a longer discharge time. We strengthened this statistically (p-value: 0.0049).
In our study, gender and age did not have a significant effect on death (p-values: 0.276459, 0.10029). Wbc, neutrophil, and magnesium values ​​did not have a significant effect on death (p-values: 0.577682, 0.073708, 0.452292). However, low lymphocyte and high CRP levels showed significant effect on death (p-values: 0.000046, 0.010678). Low calcium also had a significant effect on death (p-value: 0.000001), as did D-dimer and troponin values ​(p-values: 0.000069, 0.003491).
