Introduction: Health literacy is a multidisciplinary term that includes patient-provider interactions, involvement in the healthcare system, rights and duties, and health information-seeking habits. It has an impact on illness prevention, individual and social competency, and health outcomes. This study aimed to model the costs and outcomes associated with potentially implementing a teach-back educational intervention compared to a regular educational intervention to improve health literacy in Nigeria.
Method: A decision tree analysis was designed to capture the progression of participants through a teach back education intervention, a regular education intervention and no intervention (control). The decision tree model was built in Microsoft excel, and the various input were obtained from literature and best estimates were applicable.
Result: Baseline results from the model estimated a cost of ₦765,000 and ₦670,000 for the teach back & regular education intervention respectively, while cumulative outcomes include Quality of life gain (228.36 vs 140.96), In-Patient hospital costs reduction (-₦ 462,137.40 vs -₦ 285,270.00), Increased adherence rates (145.80 vs 90.00), Gain in self-care ability (31.21 vs 19.26) for the teach back & regular education intervention respectively. Scenario analysis showed the same trends.
Conclusion: Education remains the major channel for improving health literacy, and implementing a teach-back intervention will substantially yield more benefits and costs compared to a regular education method. By prioritising health literacy, Nigerian health authorities can empower individuals to take an active role in their healthcare, leading to improved health outcomes and overall well-being.
