Özet:

Aim: This study aims to analyze some demographic characteristics, vaccination status, and mortal causes of COVID-19 deaths retrospectively at a district level. Material and Method: This cross-sectional study retrospectively analyzed a total of 409 COVID-19 deaths between 11 March 2020 and 30 April 2022 in a large district of Istanbul with a low socioeconomic status. Age, gender, marital status, date of death, causes of death, vaccination status and dates, and PCR test dates (considered as diagnosis dates) were obtained from the District Health Directorate records. Results: More than half of those who died were male (51.3%). The average age was 70.9 ± 13.7 years. As age increases, the death number also increases. 58.5% of all deaths were over 70 years old. The marital status of more than half of the deaths (54.8%) was married. 74.3% of all deaths were unvaccinated. Of those vaccinated among deaths, 85% received all vaccine doses with only inactivated virus vaccine. The average time from diagnosis (PCR positive date) to death for COVID-19 deaths is 14.3 ± 11.0 days. The average time from the last vaccination date to death in the vaccinated group was 121.3 ± 89.8 days. This period was statistically significantly different between those who received a single dose of vaccine and those who received two or more doses. Among the diseases reported as the primary cause of death in the death notification system, acute respiratory distress syndrome ranked first with 38.4%. This is followed by pneumonia with 19.2%. Conclusion: The most striking result from our results is that most COVID-19 deaths were unvaccinated or incompletely vaccinated. Those who were vaccinated were mostly immunized with inactivated vaccines. According to the results, it can be determined that vaccines effectively protect COVID-19 patients from death. However, the preventive effect of inactivated vaccines against death in COVID-19 is limited.
