“…It is the most reported symptom in COVID-19 patients and found to be more common in severe patients, as a meta-analysis found that the incidences of fever in the total study population and in the severe patients were 89.1% and 93.5% respectively [ 30 ]. Despite that fever was less common in our study than in the other studies due to the admission criteria of Fangcang hospitals that excluded severe COVID-19 cases, our findings suggest that patients who reported having fever at the early stage of infection require longer hospitalization, which is consistent with previous studies [ 21 , 22 ]. Similarly, as a result of pulmonary inflammation caused by viral infection, radiological changes in the lungs is common among COVID-19 patients.…”

“…As a result, patients outside of Wuhan were admitted to and hospitalized in local general hospitals regardless of disease severity. In many existing studies conducted outside of Wuhan, both non-severe and severe patients who were hospitalized in tertiary hospitals were included in the study populations [ 15 , 22 , 25 , 26 ]. However, studies in the setting of Fangcang hospitals were scarce.…”

“…Many existing studies suggest that patients' characteristics that influence disease severity are likely to influence the length of stay (LOS) in hospitals [15][16][17][18][19], but no conclusion is drawn because LOS is often reported as one of the secondary outcomes without being further analyzed [20]. We only found three studies that investigated the risk factors influencing LOS among COVID-19 patients [21][22][23]. In these studies, prolonged hospitalization of COVID-19 patients was found to be associated with being female, having fever, having chronic liver or kidney disease on admission, higher creatine level, lymphopenia, and bilateral pneumonia on CT scan [21,22].…”

As a novel concept of responding to disease epidemics, Fangcang shelter hospitals were deployed to expand the health system's capacity and provide medical services for nonsevere COVID-19 patients during the outbreak in Wuhan. To give insights on patient management within Fangcang hospitals, we conducted a retrospective analysis to: 1) describe the characteristics of the patients admitted to Fangcang hospitals and 2) explore risk factors for longer length of stay (LOS). We enrolled 136 confirmed COVID-19 patients, including asymptomatic patients and those with mild symptoms, who were hospitalized in the Wuti Fangcang Hospital. 58 patients completed the treatment and discharged before 1 March 2020. After describing patients' demographic and clinical characteristics, exposure history, treatment received and time course of the disease, we conducted linear regression analysis to identify factors influencing LOS. We found that patients having fever before admission were hospitalized 3.5 days (95%CI 1.39 to 5.63, p = 0.002) longer than those without fever and that patients having bilateral pneumonia were hospitalized 3.4 days (95%CI 0.49 to 6.25, p = 0.023) longer than those with normal CT scan results. We also found weak evidence suggesting that patients with diabetes were hospitalized 3.2 days longer than those without diabetes (95%CI-0.2 to 6.56, p = 0.065). However, we observed no significant differences in LOS between symptomatic and asymptomatic patients and between patients who received treatment and those without treatment. Longer duration of hospitalization among non-severe COVID-19 patients is associated with having fever, bilateral pneumonia on CT scan and diabetes. However, being asymptomatic and using supportive medications at the early stage of infection do not have significant influences on LOS. Our study is a single-centered study with relatively small sample size. The findings provide evidence for predicting

“…LOS was also defined commonly as the number of days in hospital admission due to COVID-19. One study described it as normal or prolonged, based on their measured average LOS (<17 days – normal; >17 - prolonged) (20). Consequently, they assessed LOS as a binary outcome.…”

Background: The current pandemic, COVID-19, caused by a novel coronavirus SARS-CoV-2 has claimed over a million lives worldwide in a year, warranting the need for more research into the wider determinants of COVID-19 outcomes to support evidence-based policies. Objective: This study aimed to investigate what factors determined the mortality and length of hospitalisation in individuals with COVID-19. Data Source: This is a systematic review with data from four electronic databases: Scopus, Google Scholar, CINAHL and Web of Science. Eligibility Criteria: Studies were included in this review if they explored determinants of COVID-19 mortality or length of hospitalisation, were written in the English Language, and had available full-text. Study appraisal and data synthesis: The authors assessed the quality of the included studies with the Newcastle Ottawa Scale and the Agency for Healthcare Research and Quality checklist, depending on their study design. Risk of bias in the included studies was assessed with risk of bias assessment tool for non-randomised studies. A narrative synthesis of the evidence was carried out. Results: The review included 22 studies from nine countries, with participants totalling 239,830. The included studies quality was moderate to high. The identified determinants were categorised into demographic, biological, socioeconomic and lifestyle risk factors, based on the Dahlgren and Whitehead determinant of health model. Increasing age (ORs 1.04-20.6, 95%CIs 1.01-22.68) was the common demographic determinant of COVID-19 mortality while living with diabetes (ORs 0.50-3.2, 95%CIs -0.2-0.74) was one of the most common biological determinants of COVID-19 length of hospitalisation. Review limitation: Meta-analysis was not conducted because of included studies heterogeneity. Conclusion: COVID-19 outcomes are predicted by multiple determinants, with increasing age and living with diabetes being the most common risk factors. Population-level policies that prioritise interventions for the elderly population and the people living with diabetes may help mitigate the outbreak's impact.
