Implementation of a patient reminder system in Haiti in a socio-political crisis context: evaluation of outcomes.

ABSTRACT

BACKGROUND: In Haiti, patient's adherence to treatment and compliance with medical appointments are very challenging due to different local factors. We aimed to assess the effectiveness of a reminder system implemented in health facilities in Haiti in a context of socio-political crisis. METHODS: We used appointment data from patients aged 15 years and older between January 2021 and November 2023 from four healthcare centers in the Port-au-Prince metropolitan area. We performed descriptive analysis, crossing covariates with appointment attendance. We performed Pearson's Chi-squared test, and multivariate regression analysis using a mixed-effect logistic regression model in order to explore the association between sending reminders and appointment attendance, with and without adjustment for other patient-level covariates. RESULTS: A total of 14 108 appointments were registered on the reminder systems, with 2 479 (17.6%) attendances. Among those to whom reminders were sent, the number of attendances was 167 (17.4%) for email recipients only, 199 (36.7%) for SMS recipients only, and 19 (42.2%) for both SMS and email recipients - versus 2 094 (16.7%) for non-reminders. After adjusting on all other covariates, we found that patients to whom a reminder was sent via email (aOR 1.45; CI 1.08, 1.94), SMS (aOR 2.95; CI 2.41, 3.60), and both SMS and email (aOR 2.86, CI 1.37, 5.96) were more likely to show up on their appointment day compared to those who did not receive any reminder. Other socio-demographic factors such as being 50 years and older (aOR 1.31; CI 1.10, 1.56) compared to under 30 years, living as couple (aOR 1.23; CI 1.10, 1.37), and not having children (aOR 1.21; CI 1.07, 1.37) were significantly associated with appointment attendance. CONCLUSIONS: Our study suggests that patient reminder systems may be used to reduce non-attendance in Haiti, even in a context of socio-political crisis.
