Insights
COVID-19 deaths were more common in males, averaging 66.99 years old. Mortality rates were higher during day shifts and on workdays, with diabetes and cardiovascular disease as frequent comorbidities.
Area of Science:
- Epidemiology
- Public Health
- Infectious Diseases
Background:
- The COVID-19 pandemic posed a significant global health challenge.
- Understanding the characteristics of deceased patients is crucial for public health strategies.
Purpose of the Study:
- To analyze the demographic and clinical features of patients who died from COVID-19.
- To identify patterns in mortality related to time of day, shifts, and holidays.
Main Methods:
- A cross-sectional study of deceased COVID-19 patients at Imam Reza Hospital, Iran (March 2020 - September 2021).
- Data collected included age, gender, symptoms, and time/day of death.
- Analysis focused on demographic factors and confounding conditions like diabetes and cardiovascular disease.
Main Results:
- 3364 COVID-19 deaths were recorded; 60.46% were male, with a mean age of 66.99 years.
- Mortality was slightly higher during day shifts compared to night shifts.
- Diabetes (22.44%) and cardiovascular diseases (15.36%) were the most prevalent comorbidities.
Conclusions:
- COVID-19 mortality disproportionately affected males and older individuals.
- Peak mortality occurred during daytime shifts and on workdays.
- Comorbidities significantly influenced COVID-19 fatality rates.
Introduction:
The COVID-19 pandemic has been considered an international problem. This study aimed to survey the demographic and clinical characteristics of the deceased COVID-19 patients.
Methods:
The present cross-sectional study was performed on all deceased COVID-19 patients who died in Imam Reza Hospital, Mashhad, Iran, from March 20, 2020, to September 23, 2021. Their data, including age, gender, complaints, and clinical symptoms at the time of admission, as well as information at the time of death (hour, shift, holiday/non-holiday) were analyzed and reported.
Results:
3364 deaths due to COVID-19 have been registered during the study period (60.46% male). The patients' mean age was 66.99±16.97 (range: 1-101) years (92.7% of them were Iranian). The mortality at night shifts was less than day shifts (1643 vs. 1721). The average amount of deaths/day on holidays and workdays was (5.63 vs. 6.24). The number of deaths varied during the various hours of the day and night. Diabetes and cardiovascular diseases were the most common confounding factors, which were observed in 22.44% and 15.36% of the cases, respectively.
Conclusion:
Based on the findings of this series, COVID-19 mortality was frequently observed in male patients, those with the mean age of 66.99 years, morning shifts, and workdays.
