THE INFLUENCE OF COMPLICATION OF INTERSTITIAL LUNG DISEASE TO MORTALITY AND LENGTH OF STAY IN WARD FOR THE PATIENTS WITH PULMONARY TUBERCULOSIS

Background and Aims: Although we sometimes experienced patients with pulmonary tuberculosis complicated with interstitial lung disease (ILD), there are only limited information about the influence of complication of ILD to mortality and length of stay in ward for the patients with pulmonary tuberculosis. Methods: The information of the patients who admitted to the tuberculosis care unit of our hospital since 2015 to 2017 were reviewed with clinical chart. Patients were divided into two groups, one is ILD group and the other is non-ILD group. Mortality and length of stay in ward were compared in the two groups. Fisher’s exact test and Mann-Whitney test were used. Results: 371 patients were enrolled and the percentage of the patients with ILD was 7.3% (27/371). The mortality of the ILD group and non-ILD group were 22.2% and 11.9%, respectively (P = 0.132). The length of stay in ward of the two groups were 67. 0.3 and 55. 1.9 days respectively (P = 0.480). Conclusion: Complication of ILD for the patients with pulmonary tuberculosis resulted in the trend of higher mortality and longer stay in ward, but they were not significant.
