AbstractObjective The incidence of tuberculosis in Japan has been decreasing in the overall population but is increasing in older patients ≥90 years old. A poor performance status due to underlying diseases makes it difficult for patients with tuberculosis to receive standard oral treatment. However, there is no consensus concerning alternative treatments. This study examined the treatments and outcomes of older patients with tuberculosis and a poor performance status and determined the limitations of tuberculosis treatment for them. Methods We retrospectively enrolled 121 older patients with tuberculosis and a performance status of 3 or 4 due to underlying diseases during their hospitalization between April 2015 and March 2017 at National Hospital Organization Tokyo National Hospital. We classified them according to the drug administration route (oral, enteral, and injection routes) on admission and compared the characteristics and prognoses among the three groups. Results There were 79 patients in the oral route group, 28 (35.4%) of whom died during hospitalization. Among the 15 patients in the enteral route group, 6 (40.0%) died. Among the 27 patients in the injection route group who received non-oral agents, 22 (81.5%) died. The prognosis of the injection route group was poor, with a median survival time of 21 days. Conclusion Treatment success cannot be expected with injection treatment in patients with a poor general condition because of complications. Although injection treatment may be a viable alternative treatment, its establishment as the standard treatment cannot be currently endorsed.
