ObjectivesTo evaluate risk factors associated with 31-day unplanned readmission(s) for pulmonary tuberculosis (TB) in China.MethodsThis retrospective study enrolled patients (age, >14 years) with pulmonary TB who experienced 31-day unplanned readmissions to a specialized hospital for TB between January 2018 and December 2019. For each confirmed readmission, 2 control subjects were randomly selected from among patients with pulmonary TB but did not experience an unplanned readmission within 31 days.ResultsA total of 402 pulmonary TB patients (5.9%) experienced unplanned readmission within 31 days after discharge. In univariate analysis, readmission was associated with gender, age, insurance coverage, residing in a rural area, active smoking, chronic obstructive pulmonary disease (COPD), drug-induced hepatitis, and leaving hospital against medical advice. The final logistic regression model revealed that higher risks for unplanned readmissions were associated with male gender (odds ratio [OR] 1.44, [95% confidence interval (CI) : 1.06-1.95]), age >65 years (OR 2.94, 95%CI: 2.03-4.27), rural residence (OR 8.86, 95%CI: 6.61-11.87), active smoking (OR 2.15, 95% CI 1.37-3.40), COPD (OR 2.77, 95%CI: 1.59-4.81), and leaving hospital against physician advice (OR 4.11, 95%CI: 1.43-11.83). The median time to 31-day unplanned readmission was 24 days. Major reasons for unplanned readmission included fever, exacerbation of dyspnea, and hemoptysis.ConclusionUnplanned readmission for pulmonary TB within 31 days of discharge was higher among older males residing in rural areas, active smokers, and those leaving hospital against medical advice.Copyright: © Saudi Medical Journal.
