Introduction:viral suppression of PLHIV in Cameroon is one of the objectives of the national HIV program. The country employs several strategies and interventions to achieve this objective, including therapeutic education (TPE). Despite these deployed resources, the Ebolowa CTA recorded from December 2019 to November 2020, 308 uncontrolled viral load results. The objective was to research, and evaluate the causal effect of TPE, and build a score function to identify the cases of HVL in patients followed at the CTA.
Methods: we used the propensity score matching method with a caliper of 0.28 to obtain two comparable groups from which we calculated the impact parameters of the intervention and the odds ratio.
Results: thus the absolute difference in the risk of the absence of control of the viral load between the group that did not receive TPE and that which provided is significant, and is RRA=5.82%. Therapeutic education reduced the risk of lack of viral load control by RRR=40.74%, with an OR of 1.8. To avoid a case of uncontrolled viral load, it suffices to offer TPE sessions to NNT=17 patients.
Conclusion: the Odd ratio also confirms that the more patients participate in TPE sessions, the more likely they are to have a controlled viral load. With our data, we can predict patients likely to have a viral load with a view to creating an adapted and more specific therapeutic program to follow them. Next step carried out, case qualitative studies, to identify variables that may influence whether or not the viral load is controlled.
