Real-world evidence (RWE) in Health Economics and Outcomes Research (HEOR) refers to data and information collected from real-world sources, such as observational studies, registries, electronic health records, claims databases, and patient-reported outcomes. Unlike data from clinical trials, which are conducted in controlled settings and often involve selected patient populations, RWE is derived from the routine clinical care and experiences of patients in everyday clinical practice.
HEOR is an area of research that assesses the value of healthcare interventions, treatments, and technologies. It aims to understand their real-world effectiveness, safety, and economic impact. RWE is increasingly recognized as an important component in HEOR because it can provide valuable insights into how treatments and interventions perform in real-life scenarios, which may differ from the highly controlled environment of clinical trials.
Key characteristics of Real-world evidence (RWE) in HEOR include:
1. Observational nature: RWE is gathered from non-experimental studies, where researchers observe and analyze data from existing patient populations without intervening in their care.
2. Broader patient populations: Unlike clinical trials, which often include strict eligibility criteria, RWE reflects the diversity of patients encountered in routine clinical practice, making the findings more applicable to a wider population.
3. Longitudinal data: RWE can track patient outcomes over time, providing insights into the long-term effects and potential safety issues associated with interventions.
4. Real-world outcomes: RWE evaluates the effectiveness and real-world impact of treatments by assessing various outcomes, such as clinical effectiveness, patient-reported outcomes, quality of life, healthcare resource utilization, and cost-effectiveness.
5. Comparative effectiveness research: RWE can be used to compare different treatments or interventions, helping clinicians, payers, and policymakers make informed decisions on healthcare resource allocation.
Overall, Real-world evidence (RWE) plays a vital role in complementing the findings from clinical trials and offers valuable insights into the real-world benefits and risks associated with healthcare interventions. This evidence is crucial for informing healthcare decision-making, including clinical guidelines, reimbursement decisions, and health policy.
