Health Economics & Outcomes Research (HEOR)

Building the Evidence Package

Health economics and outcomes research (HEOR) is the foundation of building a data-driven evidence package substantiating the value proposition and differentiators in alignment with Health Technology Assessment (HTA) guidelines. HEOR comprises three essential elements.

Evidence identification with literature review

Systematic, HTA-compliant review of literature is a fundamental aspect of HEOR. These reviews encompass existing clinical trial outcomes, impact of treatments on quality of life, product comparators, economic evidence, and more. Our team performs both qualitative and quantitative reviews to identify the data required for reimbursement and eliminate risk of bias. We adapt our approach to meet your objectives, conducting literature reviews that are well-suited to your study.

Health Economic Modeling

Health Economic Modeling focuses on substantiating the value proposition and value differentiator of your product based on real-world and clinical trial data. This work entails simplifying the data by building models and generating key parameters to help the decision maker determine economic consequences. While there are many types of models, the most prevalent are cost utility, budget impact, and cost efficiency. Parexel is pioneering the trend of creating web-based data visualization solutions to drive evidence-generation decision-making with targeted product profiles and scenario testing – complementing our traditional economic modeling solutions.

Clinical Outcomes Assessments

The science of clinical outcomes assessments (COA) is intrinsic to drug development today, even as standards for use of this methodology are continually evolving. As an active participant in leading-edge industry organizations, Parexel has extensive expertise in COA. We offer strategic and scientific guidance on design, implementation and dissemination of patient-centric projects throughout the product development lifecycle, including end-to-end reporting.

Design of survey instruments entails interviewing patients to ensure that they understand how to participate, testing the integrity of the questions and evaluating the protocol. We are experts in patient-reported outcomes (PROs), including PRO licensing, translation and migration to electronic PRO (ePRO).

One of the most challenging areas in COA is in rare disease, especially because so many trials involve young children. This requires knowledge and skills beyond technical and clinical COA capabilities. At Parexel, our team has exceptional strength in pediatrics to apply to developing and validating effective COA instruments for caregivers and clinicians. Our multilingual team works with patients of all ages, all over the globe, helping our customers design COA programs that take into consideration country-specific sensitivities and nuances.
