Background
In the literature, there are different studies about the mortality and epidemiology of COVID-19 and such researchs are expected to increase even more. We purposed in our study to compare data about the mortality and epidemiology of patients who died from COVID-19 and another disease in January, February, March, April, May and June of 2020 with data of patients who died because of other diseases in the same months of 2018, 2019 and 2020 .
Materials and Methods
We evaluated the files of the patients who died in the months of January, February, March, April, May and June of 2018, 2019 and 2020 retrospectively. Patients died from COVID-19 were exact cases whose reverse transcription polymerase chain reaction was positive. We noted age, gender, nationality, marital status, social security, place of residence of all patients. Mortality in our study describes number of deaths / inpatients.
Results
The number of inpatients in 2018 was 49831, in 2019 was 46429, in 2020 was 37843 and totally was 134103. 1421 of them were inpatients from COVID-19. 39 of 1421 inpatients died because of COVID-19. Average number of mortality in 2018 was 0.92%, in 2019 1.14% and in 2020 1.47% and there was significant relationship between groups (p < 0.0001). The mortality of COVID-19 was determined 2.74 % in our hospital.
Conclusion
In conclusion, in our study, average number of deaths and mortality in 2020 were more than in 2018 and 2019. In addition, COVID-19 may have begun in February 2020, not in March, in Turkey according to the number of deaths in February and March in 2020 of our hospital. Mortality in June 2020 was less than June 2019 and June 2018. We think that our study can contribute to the last epidemiologic data in the world.
