Methods: This research reviews past quantitative studies available in the databases of NCBI-PUBMED, Springer Link, Cochrane and Google Scholar. They must be peer-reviewed articles published in English from 2017 to 1 October 2022, and the mean age of the patients being discussed is 18 years or more. As this study only reviews full articles, abstract-only texts were excluded. In addition, the data form the selected papers were extracted by three researchers. Discussion: From many factors influencing patient's length of stay, besides the fact that comorbidities affect the duration of the disease suffered by the patient, malnutrition during illness is the most dominant one.
