Tuberculosis (TB) is one of the most important infectious diseases in the world, and caused by Mycobacterium TB. In accordance with World Health Organization (WHO) report in 2020, the incidence of TB was approximately 10 million (range, 8.9-11.0 million), with 1.4 million deaths worldwide.1 In 2020, the incidence rate of TB was estimated to be 58 per 100,000 population in China.2 Although the prevalence of TB has decreased through 2 decades of effort and short-course strategy programs (such as, directly observed treatment, short course [DOTS]), China still ranks second in terms of the largest burden of TB in the world, which is also associated with enormous economic implications.3
Unplanned re-hospitalization within 31 days of discharge refers to a situation in which a patient is readmitted to hospital for the same or related disease within 31 days after initial discharge,and is considered to be a “sentinel event” reflecting poor-quality hospital care.4 Moreover, unplanned readmission(s) after hospitalization also impose a burden on patients and health care resources due to high costs.5 In 2004, hospital readmissions in the United States cost the medicare system approximately $17.5 billion, accounting for approximately one-fifth of the country’s total hospital costs.6 A cross-sectional study reported a hospital readmission rate of 5.9%, which varied among hospitals, ranging from 9.8% to 17.0% in France.7 The readmission rates continue to rise, causing widespread concern across countries. The United States and China announced in 2007 and 2011, respectively, that early unplanned readmission should be used as an important indicator for evaluating medical quality.8,9
Considering the additional costs that unplanned readmission impose to the health system, correlational research may improve our clinical decision-making on unplanned hospitalization. A systematic study in 2020, chronic obstructive pulmonary disease (COPD)-related readmission rates have differences in 30 countries, risk factors and the local healthcare environment should be interventions.10 According to a 3-year study carried out in Iran, a common cause of early readmission were drug-induced hepatitis, dyspnea.11 In addition, comorbidities and socioeconomic factors were also considered to be associated with readmission.12,13 So far, readmissions for major disease and surgical diagnoses have been studied, but the risk factors for early unplanned readmission among patients with pulmonary TB without research....
