The effect of appointment spacing model of care on virological suppression and associated factors among HIV-positive individuals on antiretroviral therapy at public health facilities of Debre Markos town, Northwest Ethiopia: interrupted time series design

Abstract

Introduction: Appointment spacing model (ASM) of care is crucial for human immunodeficiency viruses (HIV) patients receiving antiretroviral therapy in order to improve service quality and patient's clinical outcomes, including viral suppression. However, there is a paucity of information about the effectiveness of ASM on viral suppression. Therefore, this study aimed to assess the level and trends of virological suppression and associated factors among patients on antiretroviral therapy enrolled into ASM in Northwest Ethiopia.
