Quality Improvement (QI) Projects vs. Research

This guidance is intended to help investigators understand the overall difference between research activities and non-research QI activities, and it is not represented as official policy. Additionally, there may be other activities or characteristics not described below that may or may not meet the definition of research involving human subjects. Please refer to the regulatory definitions for "research" and "human subject" as well as other resources provided below. Anyone requiring an official determination about a project should submit the Determination of Human Research Worksheet in iRIS for IRB review.

QI Projects and IRB Review

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.

Definitions

Quality Improvement: an activity that is specifically initiated with a goal of improving the performance of institutional practices in relationship to an established standard.
 

Research: a systematic investigation, including research development, testing, and evaluation, designed to develop or contribute to generalizable knowledge.

  • Systematic Investigation: an activity that involves a prospective plan that incorporates data collection, either quantitative or qualitative, and data analysis to answer a question.
     
  • Generalizable Knowledge: investigations designed to generate new knowledge and expand the knowledge base of a scientific discipline or other scholarly field of study and yield one or both of the following:
    • Results that are applicable to a larger population beyond the site of data collection or the specific subjects studied.
    • Results that are intended to be used to develop, test, or support theories, principles, and statements of relationships, or to inform policy beyond the study or internal program.
       

Human Subject: a living individual about whom an investigator conducting research:

  1. Obtains information or biospecimens through intervention or interaction with the individual, and uses, studies, or analyzes the information or biospecimens; or
  2. Obtains, uses, studies, analyzes, or generates identifiable private information or identifiable biospecimens.
