Referral and treatment outcomes of tuberculosis patients who crossed the border from Japan to the philippines.

Abstract

The referral and treatment outcomes of tuberculosis (TB) patients referred from Japan to the Philippines have not yet been systematically reported. This study aimed to describe the cross-border referral process for TB patients referred from Japan to the Philippines. This is a retrospective descriptive review of the referral process between the two countries. The data on the pathways of Filipino patients with TB or latent TB infection initially treated in Japan from 2009 to mid-2018 were summarized. We calculated the proportion of the referred-and-accessed and that of the successfully treated in the health facilities in the Philippines. The Chi-square test or Fisher's exact test was applied to test significant differences between categorical data. Among the 36 Filipino TB patients referred, 83.3% (30 patients) were successful in accessing any of the health facilities. Among these, 28 patients confirmed that they had started TB treatment in the Philippines. Age groups (P = 0.17), gender (P = 0.76), planned place of residence (P = 0.44), bacteriological results (P = 0.81), and TB patient types (P = 0.96) did not show any significant differences in the referred-and-access rate. The treatment success rate among the 23 TB patients (excluding five patients who were still receiving treatment as of writing) was 91.3%. However, only three out of five multidrug-resistant TB patients successfully started treatment. The current cross-border TB patient referral mechanism between Japan and the Philippines indicated successful results. However, it needs to be enhanced by strengthening the mechanism to track referral outcomes systemically.
