In many low- and middle-income countries scarcity of local data on health outcomes and health-related quality of life (HRQoL) is a hindrance to conducting cost-effectiveness analyses. The Tunisian National Authority for Accreditation and Assessment in Healthcare (INEAS) developed a set of methodological guidelines to support pharmaceutical companies in the submission of health technology assessment (HTA) dossiers. The guidelines include INEAS’ methodological choices for pharmacoeconomic analysis, which take into consideration the specificities and constraints of the Tunisian context. We aimed to present the principal recommendations of the Tunisian guidelines for pharmacoeconomic studies, with a focus on patient-reported outcome and HRQoL measurement.

The INEAS pharmacoeconomic analysis guidelines were reviewed and the recommendations regarding outcome measurement and HRQoL were retrieved and reported.

To populate the economic model, INEAS recommends using the best available evidence. Health outcomes should be measured in terms of life-years gained and quality-adjusted life-years (QALYs); disability-adjusted life-years can be used but are not the preferred method. To estimate QALYs, INEAS favors the indirect measure of patient preferences with a validated measurement instrument. Alternatively, other measures of utility may be used, including those identified through a systematic review of the scientific literature and the publications of other HTA agencies. Justification and details of the source of the data must be provided. The utility values selected should be recent and representative of the Tunisian population, as far as possible. The guidelines refer to a set of generic preference-based HRQoL instruments, including the EuroQol five-dimensions (EQ5D), the Health Utilities Index Mark 2 (HUI2) and Mark 3 (HUI3), and the Short-Form Six-Dimension (SF-6D), but do not provide any explicit recommendations on their use.

The INEAS pharmacoeconomic analysis guidelines adhere to international best practices but provide more flexibility for overcoming the lack of local data. The INEAS economic guidelines constitutes a further milestone in the process of implementing HTA in Tunisia and in the Middle Eastern and African regions.
