Various prognostic factors for COVID-19 severity have emerged and their replication across different clinical settings providing health services is ongoing. We aimed to describe the clinical characteristics and their association with outcomes in patients hospitalised with COVID-19 in the University Hospital of Ioannina. We assessed a cohort of 681 consecutively hospitalised patients with COVID-19 from January 2020 to December 2021. Demographic data, underlying comorbidities, clinical presentation, biochemical markers, radiologic findings, COVID-19 treatment and outcome data were collected at the first day of hospitalisation and up to 90 days. Multivariable Cox regression analyses were performed to investigate the associations between clinical characteristics (hazard ratios (HRs) per standard deviation (\n                    <jats:sc>s.d.<\/jats:sc>\n                    )) with intubation and\/or mortality status. The participants' mean age was 62.8 (\n                    <jats:sc>s.d.<\/jats:sc>\n                    , 16.9) years and 57% were males. The most common comorbidities were hypertension (45%), cardiovascular disease (19%) and diabetes mellitus (21%). Patients usually presented with fever (81%), cough (50%) and dyspnoea (27%), while lymphopenia and increased inflammatory markers were the most common laboratory abnormalities. Overall, 55 patients (8%) were intubated, and 86 patients (13%) died. There were statistically significant positive associations between intubation or death with age (HR: 2.59; 95% CI 1.52\u20134.40), lactate dehydrogenase (HR: 1.44; 95% CI 1.04\u20131.98), pO\n                    <jats:sub>2<\/jats:sub>\n                    \/FiO\n                    <jats:sub>2<\/jats:sub>\n                    ratio &lt; 100 mmHg (HR: 3.52; 95% CI 1.14\u201310.84), and inverse association with absolute lymphocyte count (HR: 0.54; 95% CI 0.33\u20130.87). These data might help to identify points for improvement in the management of COVID-19 patients.\n                  <\/jats:p>","DOI":"10.1017\/s0950268822001364","type":"journal-article","created":{"date-parts":[[2022,8,16]],"date-time":"2022-08-16T03:18:48Z","timestamp":1660619928000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":2,"title":["Association of patient characteristics with clinical outcomes in a cohort of hospitalised patients with SARS-CoV-2 infection in a Greek referral centre for COVID-19"],"prefix":"10.1017","volume":"150","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1735-5839","authenticated-orcid":false,"given":"I.","family":"Rapti","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Asimakopoulos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Liontos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Kosmidou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Christaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Biros","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"O.","family":"Milionis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Tsourlos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Ntotsikas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Ntzani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Evangelou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Gartzonika","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Georgiou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Tzoulaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Tsilidis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Milionis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2022,8,16]]},"reference":[{"key":"S0950268822001364_ref28","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.m1985"},{"key":"S0950268822001364_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(20)30854-0"},{"key":"S0950268822001364_ref36","doi-asserted-by":"crossref","first-page":"499","DOI":"10.1001\/jama.2021.11330","article-title":"Association between administration of IL-6 antagonists and mortality Among patients hospitalized for COVID-19: a meta-analysis","volume":"326","author":"Shankar-Hari","year":"2021","journal-title":"JAMA"},{"key":"S0950268822001364_ref6","unstructured":"6.
