Risk factors for readmission to hospital in patients with tuberculosis in Tehran, Iran: three-year surveillance.
Tuberculosis (TB) is still a major health problem and TB hospital readmission could increase health system costs. In a retrospective study in a tertiary referral hospital for TB in Tehran, Iran, TB patients with readmission were evaluated. These TB patients in the index year who were then readmitted were compared with TB patients in the same year who were not readmitted during the follow-up period. One hundred and forty-six patients had hospital readmission within three-year follow-up with mean age of 51.6 years old of whom 78 patients (53.5%) were men. Univariate analysis revealed married status, smoking, opium smoking, and medical comorbidities (chronic obstructive pulmonary disease [COPD], hypertension, and human immunodeficiency virus [HIV] infection) as risk factors. Final logistic regression model revealed married status and smoking values of (0.478 odds ratio [OR], 0.310-0.737; 95% confidence interval [CI], P = 0.001) and (1.932 OR, 1.269-2.941; 95% CI, P = 0.002), respectively. Readmission predicted probability was 37% for married patients and 31% for active smokers. The most common medical comorbidities in the first readmission were COPD and HIV infection. Dyspnea and anti-TB drug-induced hepatitis were a common cause of early readmission, while failure and default of treatment were more frequent causes of late readmission. Admission and discharge guidelines, outpatient follow-up, and smoking cessation intervention were proposed as important factors in decreasing the readmission rate.
