Introduction: Health literacy describes patient-provider interactions, involvement in the healthcare system, rights and duties, and health information-seeking habits. It’s resultant impact on illness prevention, individual and social competency, and health outcomes make it relevant for patients and health authorities. This study aimed to model the costs and outcomes associated with 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 educational intervention, a regular educational 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 where applicable.
Result: Baseline results from the model estimated a cost of ₦765,000 and ₦670,000 for the teach- back & regular educational 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 educational 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.
