Determining if a proposed project is a non-research quality improvement (QI) activity or research involving human subjects is challenging. Federal regulations define research as "a systematic investigation, including research development, testing, and evaluation, designed to develop or contribute to generalizable knowledge".
By design, many QI projects are systematic in nature. Most QI projects do not meet the definition of research though because they are not designed to be generalizable. Research studies are intended to create new knowledge that can be generalizable to other populations and settings, while QI in healthcare uses existing knowledge to improve health care outcomes within a local health care institution or setting.
It is important to note that some QI projects may also be research (systematic and generalizable) and therefore require IRB approval. The table below illustrates some of the key differences between research and (non-research) QI.
|
RESEARCH |
QUALITY IMPROVEMENT |
Purpose |
Test a formal hypothesis. Develop or contribute to generalizable knowledge. |
Assess and/or improve a process, system, or program within a particular institution. Focus on translating existing knowledge from research into clinical practice to improve the quality of health care for individuals and populations. |
Starting Point |
A prospectively designed, formal, written research hypothesis or research question. |
An established set of standards. |
Design |
Systematic; generally follows a rigid or strict protocol that remains unchanged through the research. May involve randomization. |
Typically, an adaptive, iterative design (i.e., PDSA cycle). Generally, does not involve randomization. |
Effect on Program or Practice Evaluated |
Findings are not intended to directly affect institutional or programmatic practice. |
Findings are intended to directly affect institutional practice where the QI project is conducted. |
Benefits |
May or may not benefit directly; intended to benefit future patients. |
Directly benefits a process, system, or program; may or may not benefit participants. |
Risks |
May place participants at risk. |
Does not significantly increase risk to patients, except possible risks to privacy or confidentiality of data. |
End Point |
Answer research question. |
Use existing knowledge to improve a process, system, or program. |
Analysis |
Statistically test a hypothesis. |
Measuring outcomes after changes based on current evidence. |
