"We have nice policies but…": implementation gaps in the Ghana adolescent health service policy and strategy (2016-2020).

Introduction: Although policies for adolescent health exist in Ghana, their implementation is challenging. Availability of services for adolescent sexual and reproductive health and adolescent mental health remains less than desired, with adolescent mental health being particularly neglected despite being an important contributor to poor health outcomes. This study presents an analysis of gaps in the implementation of the Ghana Adolescent Health Service Policy and Strategy (2016-2020), including how and why the context influenced the observed implementation gaps.
