Abstract

Background

            The Covid-19 infection is an infectious disease that has plagued health care systems for over the past three years. Mortality from Covid-19 is reported to be associated with the presence of underlying diseases and older age. On the other hand, Covid-19 vaccines have been found to be effective in preventing severe disease. The aim of this study is to describe and assess the vaccination status and the comorbidities of patients who died, as a direct consequence of Covid-19 infection.

Methods

This is an observational retrospective study of adult patients admitted to a 26 bed internal medicine department and a 3 bed ICU of a military hospital of Athens from 26th of March 2020 to 31st of July 2022. The sample consisted of 52 unvaccinated patients (61.2%), 16 (18.8%) non-booster patients and 17 fully vaccinated patients (20.0%).

Results

The most common comorbidities were cardiovascular diseases (67.1%) and diabetes mellitus Type 2 (22.4%), followed by renal failure (15.3%), cancer (15.3%) and dementia (14.1%). 81.2% of patients who died, had at least one chronic underlying condition and 11.8% had more than 3 chronic medical problems.

Conclusions

Male patients, older patients and patients with comorbidities are at a greater risk of losing the battle against Covid-19. Cardiovascular disease was the most frequent comorbidity of deceased patients due to Covid-19. Vaccination against Covid-19 has been proven efficient and able to prevent mortality in patients with chronic medical conditions.
