A Systematic Review on the Readmission of COVID-19 Patient: Frequency and Individual Factors

Background and Objectives: The COVID-19 pandemic has severely damaged the world economy. Due to the COVID-19 infection, hospitalization is in high demand. Numerous COVID-19 patients are treated medically, released from the hospital, and then relapse and need to undergo treatment because they test positive. This places a strain on the health services, and the number of relapses is rarely reported in the literature. The purpose of the study is to assess individual and frequency-based factors that influence readmission of COVID-19 patients.

Methods: This study uses a systematic review of the literature, using the PICO strategy for the construction of the research question, the bibliographic search and the best available scientific information in the systematization.

Results: The traits of the chosen studies are compiled in Table 3. In the period from March 30, 2020, to February 23, 2021, 28 studies were published. The majority of studies were carried out in China, with Wuhan reporting the highest number. There were also some studies conducted outside of China, including one from South Korea, six from the United States specifically, one from Spain, and one from Turkey. Age 65 was a risk factor for readmission or re-positive rates, which ranged from 3.6% to 67.1%.

Conclusion: The hospital strictly controls Covid-19 patients before they are allowed to leave the hospital to prevent recurrence as a result of relapse in Covid-19 patients during the pandemic.
