We performed a systematic review on the relationship between comorbidity and length of hospital stay (LOS) and hospital costs (HC). Electronic databases were systematically searched for relevant studies, conducting methodological quality assessment and best-evidence synthesis: 317 articles were identified, 10 of which fit the inclusion criteria; nine studies determined the relationship between comorbidity and LOS, with eight reporting a positive correlation; five studies were considered to be of high quality, four of which found a positive correlation; two studies analyzed the relationship between comorbidity and HC and reported significantly higher HC for patients with comorbidities, and were considered to be of high quality. In conclusion, there is limited evidence that patient comorbidity has a positive correlation with LOS and HC.
