It was suggested that statin may improve the outcomes of pneumonia patients. However, there are sparse data regarding this topic in ethnic Chinese populations. In the present study, we investigated associations between previous statin use and pneumonia outcomes in Taiwan with a large-scale matched cohort study. A total of 11 576 patients with pneumonia were selected, comprising 2894 patients with previous statin use and 8682 matched patients. We used a separate conditional logistic regression to explore relationships between statin use and each clinical outcome, including 'intensive care unit admission,' 'use of mechanical ventilation,' 'acute respiratory failure' and 'in-hospital death'. We found that patients who were statin users were 0.81 (95% CI 0.74-0.89), 0.80 (95% CI 0.71-0.89), 0.84 (95% CI 0.75-0.94) and 0.69 times (95% CI 0.57-0.85) less likely to be admitted to the intensive care unit, to have acute respiratory failure, to need mechanical ventilation, and to die in the hospital, respectively, than patients who were not statin users. In addition, it consistently revealed that compared with patients who were not statin users, regular statin users had lower ORs of intensive care unit admission, acute respiratory failure, the use of mechanical ventilation and in-hospital death. However, there were no significant differences in the above adverse outcomes between irregular users of statin and non-statin users. We concluded that patients with regular previous statin use were significantly associated with favourable outcomes during admission for pneumonia in Taiwan.
