[COVID-19-associated deaths].

Introduction: In December 2019, the new infectious coronavirus disease 2019 (COVID-19) first appeared in China. So far, no systematic evaluation of death certificates of COVID-19-associated deaths has been presented.

Methods: The death certificates of all deaths in Munich during the period from 1 March to 31 July 2020 were analyzed. The previously defined inclusion criteria were the indication of corona, COVID-19 and SARS-CoV‑2 in the death certificates. The variables were entered anonymously according to a developed key. The collected data were evaluated descriptively.

Results: In the period under investigation, a total of 5840 people died in the Munich City area. Of these deaths 332 (5.7%) were COVID-19-associated. In 281 deaths (84.6%) there was a definite COVID-19 and in 51 deaths (15.4%) the suspicion of this disease. The most frequent causes of death were acute respiratory distress syndrome or respiratory insufficiency (59.1%), multiple organ failure (21.4%) and sepsis (10%). An average of 1.8 pre-existing illnesses were reported in the death certificates. Most frequently mentioned were diseases of the circulatory system (54.8%), the nervous system (22.8%) and metabolic diseases (18.9%). The average age at death was 79 years and the most frequent place of death was a hospital (85%). An autopsy was attempted by the doctors who issued the death certificates for 18.1% of the collective, most frequently in the case of unexplained or unnatural causes of death and young age of the deceased. Clinical pathological autopsies were performed on 11% of the collective and judicial autopsies on 1%.

Discussion: This study is the first evaluation of death certificates with respect to the novel infectious COVID-19. Number and essential characteristics of COVID-19-associated deaths in Munich during the so-called first wave could be mapped. The interest of physicians in autopsies was rather low despite the appearance of a new infectious disease.
