Is Outcomes Research on Cancer Ready for Prime Time?

Contemporary treatment of patients with cancer has been challenged by the same influences that have stimulated broad interest among stakeholders in assessing the outcomes or “results” of medical care. These interrelated external forces include growing awareness of practice variations, increased recognition of the patient’s central role in decision making, acknowledgment that treatment decisions for situations where cure is not possible require explicit metrics to assess trade-offs between length and quality of life, strong interest in cost containment, and broad public concern that efforts to rationalize spending may have led to decreases in quality of care. Clinical and health services researchers interested in cancer diagnosis and treatment have striven to address these issues and have been in the forefront of efforts to develop and use valid measures of health-related quality of life. However, the current challenges to the field of outcomes research are equally applicable to those applying its tools and methods to the study of cancer: lack of standardization of outcomes measures, limited evidence that assessing outcomes of care is followed by improved outcomes in practice, and development of a research infrastructure that links the products of outcomes research with informed, shared decision making in routine practice. The purpose of this article is to provide a brief overview of lessons learned from the first decade of outcomes research sponsored by the Agency for Healthcare Research and Quality that will inform suggested directions for future directions for cancer outcomes research.
