There was a predominance of men (59.3% (283)) burdened by comorbidities, with increased inflammation at admission. Patients aged \u2265 81 years were significantly more likely to be admitted to and die in infectious diseases units (IDU) due to respiratory failure, their hospital stays were shorter, and they were most likely not to receive specialist treatment. The most common COVID-19 complications included acute kidney injury in 31.2% (149) patients and thromboembolic complications in 23.5% (112). The course of hospitalisation was complicated by healthcare-associated infections (HAI) in 33.3% (159) of cases, more often in those treated with baricitinib (p &lt; 0.001). The initial use of an antibiotic, although common (94.8% (452)), was unwarranted in almost half of the cases (47.6% (215)). Complications of hospitalisation (46.1% (220)) and adverse events involving staff (49.7% (237)) were found in almost half of the patients. In 88.7% (423) of the cases, death was due to respiratory failure in the course of SARS-CoV-2 infection. Adverse events during hospitalisation should be considered as an additional factor that, in addition to the infection itself, may have influenced the death of patients.<\/jats:p>","DOI":"10.3390\/v15071430","type":"journal-article","created":{"date-parts":[[2023,6,26]],"date-time":"2023-06-26T02:05:02Z","timestamp":1687745102000},"page":"1430","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Unpacking the Complexity of COVID-19 Fatalities: Adverse Events as Contributing Factors\u2014A Single-Center, Retrospective Analysis of the First Two Years of the Pandemic"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4725-123X","authenticated-orcid":false,"given":"Aleksander","family":"Zi\u0144czuk","sequence":"first","affiliation":[{"name":"Department of Forensic Medicine, Wroclaw Medical University, 50-369 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marta","family":"Rorat","sequence":"additional","affiliation":[{"name":"Department of Forensic Medicine, Wroclaw Medical University, 50-369 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krzysztof","family":"Simon","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases and Hepatology, Wroclaw Medical University, 50-369 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0110-0276","authenticated-orcid":false,"given":"Tomasz","family":"Jurek","sequence":"additional","affiliation":[{"name":"Department of Forensic Medicine, Wroclaw Medical University, 50-369 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"533","DOI":"10.1016\/S1473-3099(20)30120-1","article-title":"An interactive web-based dashboard to track COVID-19 inealime","volume":"20","author":"Dong","year":"2020","journal-title":"Lancet Infect.
