The impact of performance status on tuberculosis-related death among elderly patients with lung tuberculosis-related death among elderly patients with lung tuberculosis

Background: While advanced age is a main prognostic factor in patients with tuberculosis, the factors that specifically affect tuberculosis-related death are unclear because elderly people are at a risk for other age-related lethal diseases.We hypothesized that performance status, a prognostic factor originally developed for cancer patients, would predict the prognosis of elderly tuberculosis patients.We aimed to assess the impact of performance status on
