Improving estimators of HIV mortality and retention in care by linking clinical cohort data with national registries in Mexico.

ABSTRACT:

Introduction

Loss to follow-up (LTFU) bias mortality estimates in cohort studies. This study aimed to estimate the corrected incidence of LTFU, retention in care, and mortality rates in people with HIV (PWH) in an HIV/AIDS Clinic in Mexico City, by linking clinic and national registry data, and to identify characteristics associated with LTFU.

Methods

We linked adult PWH who met lost to follow-up criteria while enrolled at a Mexico City clinic with the national death registry, a national administrative HIV database and a clinical national registry in May 2019 and January 2021. We defined lost to follow-up as absence of a documented clinical contact in the previous 180 days. We estimated corrected LTFU, retention in care, mortality rates, and survival, and identified characte
