Factors associated with the duration of hospitalisation among COVID-19 patients in Vietnam: A survival analysis

Abstract

Background The median duration of hospital stays due to COVID-19 has been reported in several studies on China as 10−13 days. Global studies have indicated that the length of hospitalisation depends on different factors, such as the time elapsed from exposure to symptom onset, and from symptom onset to hospital admission, as well as specificities of the country under study. The goal of this paper is to identify factors associated with the median duration of hospital stays of COVID-19 patients during the second COVID-19 wave that hit Vietnam from 5 March to 8 April 2020. Method We used retrospective data on 133 hospitalised patients with COVID-19 recorded over at least two weeks during the study period. The Cox proportional-hazards regression model was applied to determine the potential risk factors associated with length of hospital stay. Results There were 65 (48.9%) females, 98 (73.7%) patients 48 years old or younger, 15 (11.3%) persons with comorbidities, 21 (16.0%) severely ill patients and 5 (3.8%) individuals with life-threatening conditions. Eighty-two (61.7%) patients were discharged after testing negative for the SARS-CoV-2 virus, 51 were still in the hospital at the end of the study period and none died. The median duration of stay in a hospital was 21 (IQR: 16–34) days. The multivariable Cox regression model showed that age, residence and sources of contamination were significantly associated with longer duration of hospitalisation. Conclusion A close look at how long COVID-19 patients stayed in the hospital could provide an overview of their treatment process in Vietnam, and support the country's National Steering Committee on COVID-19 Prevention and Control in the efficient allocation of resources over the next stages of the COVID-19 prevention period.

Treatment Profiles and Clinical Outcomes of Covid-19 Patients at Private Hospital in Jakarta

“…The mean duration of stay due to COVID-19 has been reported in several studies in China as 10-13 days (Guan et al, 2020; Wang et al, 2020). However, the length of stay depends on various factors, such as the time elapsed from exposure to the onset of symptoms, and from the time of onset to the time of hospital admission, as well as various factors related to the countryspecific context (Thai et al, 2020). Older age, higher SOFA scores, and d-dimers of more than 1 μ g / mL are associated with an increased likelihood of death (Zhou et al, 2020).…”

Considerations for diagnostic COVID-19 tests

“…In other developing regions, similar initiatives were promoted by regional and international health surveillance institutes. In South-East Asia this was pushed, for instance, by the Vietnam National Steering Committee 106 , whereas, for instance in South America, the state of São Paulo in Brazil actively supported the use of diagnostics in maintaining social distancing guidelines 107 . Still, and despite this type of support, suboptimal and delayed diagnostics in many developing regions and consequent problems in the efficacy of disease suppression were expected 108 – 110 .…”

Acute myocardial infarction secondary to COVID-19 infection: A case report and review of the literature

“…[31][32][33] Numerous longlasting complications of prolonged critical care have been described, 34 likely directly applicable to critically ill COVID-19 patients given prolonged length of stay in the ICU. 35,36 Given the risk of thrombotic complication in patients with COVID-19, clinical guidelines have been issued recommending the use of anticoagulation in hospitalized COVID-19 patients with continuation for those with high risk. 37 Clinically, a high level of suspicion should be raised for thrombosis in patients with SARS-CoV-2 infection and appropriate imaging ordered for confirmation so therapeutic anticoagulation can be initiated to prevent long term complications of Fig.…”
