It connects leadership oversight with measurement, staff and patient input, corrective action, and follow-up. Compliance is one part of that work: meeting a rule does not by itself prove that care is safe or high quality.
What quality assurance does in healthcare
QA is not a one-time inspection or a stack of completed forms. It is a repeating organizational process: set priorities, measure performance, investigate concerns, make changes, and monitor what happens next. The AHRQ Quality Indicators toolkit describes measures and practical resources that help hospitals identify areas for investigation, select improvement priorities, engage staff, use evidence-based practices, and track performance over time.
The system should look beyond whether a policy exists. It should ask whether people follow the process, whether the process works as intended, and whether patients experience better outcomes. That requires leadership accountability as well as the participation of the staff who deliver care and the patients and families who experience it.
How the quality-improvement loop works
1. Set priorities and assign accountability
Leaders identify high-risk, high-volume, or problem-prone processes and provide oversight and resources for improvement. A useful priority is specific enough to measure and important enough to warrant action, such as delays in a care transition or medication-related safety concerns. For US hospitals, the governing body has a role in overseeing the hospital-wide QAPI program; details are discussed in the 2023 AHRQ-hosted webinar described below.

2. Measure performance and identify gaps
Indicators can reveal patterns that deserve closer review and show whether performance changes over time. AHRQ’s Quality Indicators use hospital inpatient administrative data to measure and track aspects of quality and patient safety. These measures are one view of care: they do not replace clinical review, frontline staff knowledge, or patients’ accounts of what happened.
Patient-experience measures add information that administrative data may not capture. CAHPS surveys are designed around questions for which patients may be the best or only source. Using patient feedback alongside clinical and operational measures can help an organization see both what happened and how care was experienced.
3. Investigate events and learn from them
When a measure signals a concern—or a patient or staff member reports an event—investigation should examine the process and conditions that contributed to it, not default to blaming one person. Review may include adverse events, near misses, variation in how work is done, and patient feedback. AHRQ’s hospital patient-safety resources include safety-culture tools, Patient Safety Organization information, and CANDOR resources for responding to harm.
Rank #2
CANDOR is a communication-and-resolution approach that emphasizes candid, empathetic communication and timely resolution when a patient is harmed. Such approaches connect event response with organizational learning rather than treating a report as an end in itself.
4. Make a change and check whether it helped
Improvement work should specify the measure being addressed, the starting point, the change introduced, the period observed, and the result. Staff need to understand and be able to carry out the revised process. Monitoring after implementation helps show whether the change was sustained, whether it produced the intended improvement, and whether it created new problems.
AHRQ’s toolkit supports self-assessment, choosing measures and evidence-based practices, staff engagement, and ongoing monitoring. The point is not to collect data for its own sake: measurement becomes useful when it guides action and helps assess whether that action worked.
Compliance and patient safety are connected, but not identical
Compliance means meeting applicable legal, regulatory, accreditation, contractual, and internal requirements. Patient safety and quality improvement ask whether care processes prevent harm and deliver the outcomes patients need. A QA system can connect the two through documented oversight, measurement, event review, corrective action, and monitoring. But passing a compliance review does not, by itself, establish that care is safe or effective.
What the US hospital QAPI rule requires
For US hospitals, the federal QAPI requirement in 42 CFR 482.21 provides a concrete compliance anchor. The regulation states: “The hospital must develop, implement, and maintain an effective, ongoing, hospital-wide, data-driven quality assessment and performance improvement program.” It also assigns the governing body responsibility for ensuring that the program reflects the hospital’s complexity and services, includes departments and services—including contracted services—and focuses on improved health outcomes and the prevention and reduction of medical errors. Hospitals must maintain and demonstrate evidence of the program for CMS review.

Requirements can vary by provider type, state, and jurisdiction. The quoted language is reproduced in an AHRQ-hosted National Action Alliance webinar, which identifies March 9, 2023, as the date of the CMS guidance update and references QSO-23-09-Hospital.

Why safety culture and patient participation matter
Technical measures alone cannot reveal every weakness in a care system. Staff must be able to raise concerns, teams need reliable communication, and patients and families should have a meaningful way to share what they experienced. AHRQ’s Patient Safety Structural Measure offers five domains for organizing this work: leadership commitment to eliminating preventable harm; strategic planning and policy; safety culture and a learning health system; accountability and transparency; and patient and family engagement. It is a framework for discussion, not a universal or exhaustive QA checklist.
For teamwork and communication, AHRQ’s TeamSTEPPS 3.0 organizes evidence-based training around leadership, situation monitoring, mutual support, and communication. Used alongside measurement and review, teamwork practices can help staff coordinate care and address risks as they arise.
For an additional view of adverse events, AHRQ describes the Quality and Safety Review System (QSRS) as a way to measure adverse-event rates among Medicare hospital patients and create a nationally representative baseline for assessing safety initiatives. That measure has a defined population and purpose; it should not be mistaken for a complete account of safety in every setting.

What historical improvement figures can—and cannot—show
Older examples illustrate why measurement and improvement efforts can matter, but they are not current national rates or guarantees of future results. A 1998 US Department of Health and Human Services report, last reviewed by AHRQ in June 2018, attributed the following historical outcomes to reported quality initiatives:
- New York State cardiac-bypass mortality fell 50% over five years, associated in the report with the release of hospital quality data.
- A Michigan hospital cardiac-care unit reported an 80% reduction in drug-reaction complications.
- LDS Hospital reported a 75% reduction in antibiotic-related adverse drug reactions after a quality-improvement program.
The same report cited a 1997 National Committee for Quality Assurance survey finding that 60% of diabetics age 31 and older in surveyed managed-care plans had not received a recommended eye exam in the previous year. That is a historical survey result, not an estimate of current prevalence. The report and its examples are available through AHRQ’s account of the 1998 national quality report.
