Emerging data has shown increased risks of severe infections, increased in ICU admissions, longer durations of admission, and increased mortality among coronavirus disease 2019 (COVID-19) patients with diabetes. We performed a subgroup analysis comparing the outcomes of patients diagnosed with DM (n\u2009=\u20092191) versus patients without DM (n\u2009=\u20098690) on our data from our study based on a nationwide, comparative, retrospective, cohort study among adult, hospitalized COVID-19 patients involving 37 hospital sites from around the Philippines. We determined distribution differences between two independent samples using Mann\u2013Whitney U and t tests. Data on the time to onset of mortality, respiratory failure, intensive care unit (ICU) admission were used to build Kaplan\u2013Meier curves and to compute for hazard ratios (HR). The odds ratios (OR) for longer ventilator dependence, longer ICU stay, and longer hospital stays were computed via multivariate logistic regression. Adjusted hazard ratios (aHR) and ORs (aOR) with 95% CI were calculated. We included a total of 10,881 patients with confirmed COVID-19 infection (2191 have DM while 8690 did not have DM). The median age of the DM cohort was 61, with a female to male ratio of 1:1.25 and more than 50% of the DM population were above 60\u00a0years old. The aOR for mortality was significantly higher among those in the DM group by 1.46 (95% CI 1.28\u20131.68; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) as compared to the non-DM group. Similarly, the aOR for respiratory failure was also significantly higher among those in the DM group by 1.67 (95% CI 1.46\u20131.90). The aOR for developing severe COVID-19 at nadir was significantly higher among those in the DM group by 1.85 (95% CI 1.65\u20132.07; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). The aOR for ICU admission was significantly higher among those in the DM group by 1.80 (95% CI 1.59\u20132.05) than those in the non-DM group. DM patients had significantly longer duration of ventilator dependence (aOR 1.33, 95% CI 1.08\u20131.64; <jats:italic>p<\/jats:italic>\u2009=\u20090.008) and longer hospital admission (aOR 1.13, 95% CI 1.01\u20131.26; <jats:italic>p<\/jats:italic>\u2009=\u20090.027). The presence of DM among COVID-19 patients significantly increased the risk of mortality, respiratory failure, duration of ventilator dependence, severe\/critical COVID-19, ICU admission, and length of hospital stay.<\/jats:p>","DOI":"10.1038\/s41598-021-03898-1","type":"journal-article","created":{"date-parts":[[2021,12,24]],"date-time":"2021-12-24T11:02:55Z","timestamp":1640343775000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["The
