Improving Healthcare Air Quality: A Continuous Quality Improvement Strategy to Support

Accreditation and Patient Safety

Healthcare organizations are continuously challenged to improve patient safety, ensure regulatory compliance, and demonstrate high-quality care. While much of this work has traditionally focused on hand hygiene, sterilization, and medication safety, air quality management is increasingly recognized as an essential component of continuous quality improvement (CQI) programs. Maintaining clean, safe air is not only critical for infection prevention but also directly supports compliance with accreditation requirements from The Joint Commission, DNV, and the Accreditation Association for Ambulatory Health Care (AAAHC). 

The Link Between Air Quality and Patient Safety

The perioperative and inpatient care environments are uniquely vulnerable to airborne pathogens and contaminants. Surgical site infections (SSIs), respiratory illnesses, and cross-contamination risks can all be exacerbated by inadequate ventilation, poor air exchange rates, or lapses in filtration. Beyond infection prevention, air quality affects staff well-being, environmental comfort, and even operational efficiency. 

In recent years, healthcare-associated infections (HAIs) have drawn heightened scrutiny from accrediting bodies and regulatory agencies. The Centers for Medicare & Medicaid Services (CMS) links reimbursement to infection outcomes, while accrediting bodies have reinforced their expectations that hospitals and ambulatory facilities maintain strict environmental controls.

Accreditation Standards and Expectations

The Joint Commission

The Joint Commission emphasizes air quality management under the Environment of Care (EC) standards, particularly EC.02.05.01, which requires hospitals to manage risks associated with their utility systems. Specific elements of performance include maintaining air pressure relationships, filtration, and humidity in critical care areas such as operating rooms, isolation rooms, and sterile processing departments. Surveyors often assess whether facilities not only meet technical requirements but also monitor performance as part of a CQI process.

DNV

DNV Healthcare, which integrates ISO 9001 quality management principles into its accreditation model, places strong emphasis on continuous monitoring, documentation, and corrective action. For air quality, this means facilities must go beyond compliance checklists to demonstrate that air quality metrics are being consistently measured, trended over time, and acted upon when variances are identified. CQI in this context requires organizations to establish measurable goals, track performance, and show evidence of ongoing improvement efforts.

 AAAHC

The Accreditation Association for Ambulatory Health Care (AAAHC) requires ambulatory surgery centers and outpatient clinics to maintain safe, sanitary environments, with specific attention to ventilation and infection control practices. In the ambulatory setting, where resources may be leaner, AAAHC surveyors look for clear policies on HVAC system maintenance, documentation of filter changes, and adherence to air exchange requirements in surgical and procedure rooms. Facilities must demonstrate that air quality oversight is not a one-time task but an integral part of their quality improvement initiatives.

Air Quality as Continuous Quality Improvement

Viewing air quality through a CQI lens transforms compliance from a static requirement into an active process of improvement. Here are several ways facilities can strengthen their approach:

1. Baseline Assessments – Conduct comprehensive audits of current air handling systems, including ventilation, filtration, humidity control, and monitoring practices. Use these audits to establish a baseline for improvement.
2. Data-Driven Monitoring – Implement systems that provide real-time or near-real-time data on air quality metrics. Continuous monitoring allows for early identification of issues and supports timely corrective actions.
3. Interdisciplinary Collaboration – Involve infection preventionists, biomedical engineers, facilities staff, perioperative nurses, and quality leaders in air quality oversight. This ensures that clinical, technical, and operational perspectives are represented in improvement efforts.
4. Integration into QAPI Programs – Incorporate air quality metrics into Quality Assessment and Performance Improvement (QAPI) initiatives, a key expectation of all three accrediting bodies. Track trends, set measurable goals, and present results in quality committee meetings.
5. Education and Awareness – Train frontline staff to understand the importance of air quality in patient safety. Staff should know how to report environmental concerns and recognize when air quality controls (e.g., positive/negative pressure) are not functioning as intended.
6. Link to Patient Outcomes – Where possible, correlate air quality metrics with infection outcomes, procedure delays, or staff safety reports. Demonstrating this link reinforces the value of investments in air quality management.

Moving Beyond Compliance 

Too often, healthcare organizations view accreditation standards as the ceiling for performance. However, in the area of air quality, accrediting bodies expect organizations to move beyond minimal compliance toward demonstrable continuous improvement. The Joint Commission, DNV, and AAAHC all recognize that safe care requires proactive identification of risks and evidence of measurable progress.

Facilities that embed air quality management into their CQI culture position themselves not only for successful surveys but also for sustainable improvements in patient safety. This proactive stance also strengthens staff confidence and public trust, as patients and families increasingly look for evidence that organizations are doing everything possible to protect them. 

Conclusion

Air quality is no longer a hidden or purely technical issue; it is a core patient safety priority and a critical element of accreditation readiness. By treating air quality management as part of continuous quality improvement, healthcare organizations can align with The Joint Commission, DNV, and AAAHC expectations, reduce infection risks, and demonstrate their commitment to the highest standards of care.

In the pursuit of safer outcomes and stronger survey performance, healthcare leaders should view every cubic foot of clean, well-managed air as part of their promise to deliver safe, high-quality, and accredited care.
