The efficacy-effectiveness (EE) gap shows treatment outcomes differ between clinical trials and real-world practice. This gap impacts survival, quality of life, and costs, influencing healthcare decisions.
Area of Science:
- Health Services Research
- Clinical Trials
- Comparative Effectiveness
Background:
- The efficacy-effectiveness (EE) gap highlights discrepancies between controlled clinical trial results and real-world patient outcomes.
- This gap traditionally focuses on survival differences, potentially overlooking other critical patient and system impacts.
Purpose of the Study:
- To broaden the understanding of the EE gap beyond survival outcomes.
- To emphasize the importance of considering quality of life, toxicity, cost-effectiveness, and patient time in treatment decisions.
Main Methods:
- Review of existing evidence on EE gaps in various domains.
- Commentary on the implications of these gaps for patients, clinicians, and healthcare systems.
Main Results:
- Evidence supports the existence of EE gaps in quality of life, time toxicity, and cost-effectiveness.
- These broader EE gaps can lead to unrealistic expectations regarding therapy benefits.
Conclusions:
- The EE gap encompasses more than just survival, affecting quality of life, toxicity, and economic factors.
- Further research is crucial to fully understand and address these multifaceted EE gaps for informed clinical and healthcare policy decisions.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
