Incidence, causes, and risk factors for unplanned readmission in patients admitted with pulmonary tuberculosis in China.

Introduction: To investigate the incidence, causes, and risk factors for unplanned readmission within 30 days of discharge in patients with pulmonary tuberculosis (TB). Methodology: The clinical data of 1,062 patients with confirmed pulmonary TB who were admitted to our hospital from October 2018 to October 2021 were analysed retrospectively. The subjects were divided into a readmission group (354 cases) and a non-readmission group (708 cases) according to whether there was an unplanned admission within 30 days of discharge. We analysed the risk factors for unplanned readmission within 30 days after discharge with pulmonary TB. Results: The incidence of unplanned readmission in patients with pulmonary TB was 5.2%. Being female (OR = 0.63, 95% CI: 0.434-0.942) and living in cities (OR = 0.218, 95% CI: 0.151-0.315) were protective factors for the readmission of patients with TB (p < 0.05). However, being = 65 years old (OR = 2.574, 95% CI: 1.709-3.870), being a smoker (OR = 2.773, 95% CI: 1.751-4.390), having chronic obstructive pulmonary disease (COPD) (OR = 3.373, 95% CI: 1.708-6.660), having viral hepatitis (OR= 2.079, 95% CI: 1.067-4.052), receiving nonstandard treatment (OR = 15.620, 95% CI: 10.413-23.431), having medical side effects (OR = 6.138, 95% CI: 3.798-9.922) and l unauthorised discharge (OR = 2.570, 95% CI: 1.509-4.376) were risk factors for the readmission to hospital of patients with TB (p < 0.05). Conclusions: Gender, age, place of residence, smoking, COPD, hepatitis, non-standard treatment, adverse drug reactions and unauthorised discharge were risk factors of TB for unplanned readmission.
