1.6 Research vs. Quality Improvement


Key Differences at a Glance

QI vs. Research Comparison

Dimension Quality Improvement Research

Purpose

Tests or implements changes to improve local systems and processes

Builds new, generalizable knowledge for broader application

Approach

Puts evidence-based practices into action and measures whether they work in your setting

Develops new theories or compares interventions for broader applicability

Oversight

Typically does not require IRB — but always check your institution’s policy

Usually requires IRB approval and informed consent

Dissemination

QI projects can and should be published and shared so others can learn from your experience

Results contribute to the broader scientific literature

Timeline

Rapid-cycle testing (days to weeks per PDSA cycle)

Longer study periods with defined enrollment and follow-up

Generalizability

Focused on local context — what works here, for our patients

Designed to produce findings applicable to other settings

Data Use

Data used for real-time improvement and learning

Data used for hypothesis testing and statistical analysis

⚠️ Keep in Mind

Always check your institution’s policies regarding IRB approval. The line between QI and research can sometimes be unclear, especially when projects are designed to generate publishable findings, when interventions are novel, or when data will be shared externally. When in doubt, consult your IRB or research compliance office early — they can help you determine whether your project meets the definition of research and what review, if any, is needed.
