IRB Review Versus Quality Improvement: Key Distinctions

One of the most common questions in healthcare quality is whether a project requires Institutional Review Board (IRB) review. Understanding the distinction between quality improvement and human subjects research is important for practice and for the CPHQ exam.

Defining Quality Improvement

Quality improvement activities are designed to improve care delivery processes within a specific institution. The primary intent is to improve the quality of care for patients within that organization. QI projects typically use existing data, apply evidence-based interventions, and measure results within the local context. The knowledge gained is primarily for internal use, though it may be shared more broadly.

Defining Human Subjects Research

Research involves a systematic investigation designed to develop or contribute to generalizable knowledge. Human subjects research includes any activity where researchers interact with living individuals or obtain identifiable private information. The key distinguishing factor is the intent to produce generalizable knowledge that extends beyond the specific institution. Research requires prospective IRB review and informed consent from participants.

The Gray Area

Many projects fall into a gray area between QI and research. A project may begin as QI but evolve into research if the team decides to publish findings or compare results across multiple sites. Some institutions use decision tools or checklists to help project leaders determine whether IRB review is needed. When in doubt, consult your organization's IRB office for guidance. They can provide a formal determination letter that protects both the project team and the institution.

Common Decision Criteria

Several factors help distinguish QI from research. QI projects typically implement established best practices, while research tests new or unproven interventions. QI benefits the patients involved, while research may or may not benefit participants directly. QI uses data collected as part of routine care, while research may require additional data collection. QI has minimal risk beyond standard care, while research may introduce additional risk.

CPHQ Exam Relevance

The CPHQ exam may include questions about when IRB review is required, the ethical principles underlying research protections, and the characteristics that distinguish QI from research. Be familiar with the Belmont Report principles (respect for persons, beneficence, and justice) and how they apply in the healthcare quality context.
