Seventy patients treated for COVID-19 by Østfold Hospital Trust.

Background: There is a need for further data on the COVID-19 situation in Norway. Our aim was to describe the patients admitted to our local hospital with COVID-19 in the spring of 2020.
Material and Method: Data were retrieved retrospectively from our local quality register for COVID-19 and include all patients admitted to Østfold Hospital in the period 10 March 2020-31 May 2020.
Results: A total of 70 patients were admitted, of whom 47 (67 %) were men. The mean age was 59 years (range 18-95). The most common comorbid conditions were obesity (n = 22, 31 %), chronic coronary artery disease (n = 21, 30 %) and diabetes (n = 17, 24 %). Thirteen patients (19 %) had no comorbidities. The most common symptoms were cough (n = 56, 80 %), dyspnoea (n = 51, 73 %) and fever (n = 48, 69 %). The most frequent complications were cardiac manifestations (n = 18, 26 %), acute respiratory distress syndrome (n = 14, 20 %) and acute kidney injury (n = 9, 13 %). Four (6 %) patients developed venous thromboembolism. Twenty patients (29 %) became critically ill. Thirteen (19 %) received treatment in the intensive care unit, and seven (10 %) died while in hospital.
Interpretation: Most of those admitted were middle-aged men. Many had no comorbidities. The most frequent non-respiratory complications were cardiac manifestations and kidney injury. A large proportion of patients became critically ill secondary to acute respiratory distress syndrome.
