Factors Associated with Attrition: Analysis of an HIV Clinic in Japan

This study evaluated the impact of a public medical interpreter on the follow-up clinic attendance rate of foreign-born people with HIV who live in Japan. Participants were patients who visited Nagoya Medical Center from 2009 to 2016. Lost to follow-up was defined as an absence from follow-up visits for more than six months without any notification. A log-rank test was conducted to compare the lost-to-follow-up rates by patients' nation of origin and medical interpreter use. Of the 931 participants, 114 were foreign patients, whose overall attendance rate at 5 years was 75.5%, which was significantly lower than that of Japanese patients (94.1%, p < 0.001). There was no significant difference in regular attendance with respect to medical interpreter use (p = 0.09). Social support in addition to a medical interpreter may be needed to improve attendance rates in the study population.
