Installation of an Advanced Air Purification System in a Hospital Setting Led to Improved Environmental and Clinical Outcomes

A peer-reviewed study published in RenaRum examining the environmental and clinical effects of installing LifeAire’s advanced air purification system in a hospital setting. The study measured changes in airborne and surface pathogen burden, volatile organic compound levels, and clinical outcome metrics following LifeAire installation, contributing to the growing body of peer-reviewed operational evidence supporting advanced air purification as a clinical intervention in acute care hospital environments.

The impact of comprehensive air purification on patient duration of stay, discharge outcomes, and health care economics: A retrospective cohort study

A peer-reviewed, IRB-approved retrospective cohort study examining the impact of comprehensive air purification on patient length of stay, discharge outcomes, and healthcare economics at St. Luke’s University Health Network. The study compared 8,255 patients across a LifeAire-protected medical-surgical unit and a HEPA-only control unit over 12 months. Documented outcomes in the LifeAire-protected unit included a 39.5% reduction in patient length of stay, improved discharge metrics, and 23% cost savings per patient bed. The study confirms a direct relationship between advanced air purification and measurable improvements in both clinical and economic hospital performance. Published in Surgery, September 2020.

Comprehensive and live air purification as a key environmental, clinical, and patient safety factor: A prospective evaluation

A peer-reviewed book chapter published in Vignettes in Patient Safety, Volume 4, edited by Stanislaw P. Stawicki and Michael S. Firstenberg (IntechOpen, March 2019). The chapter presents the first comprehensive prospective evaluation of infectious and aerosolized pathogens — including their speciation, location, and concentration — within a typical hospital setting, and examines the relationship between airborne pathogens and air filtration methodologies in the context of the molecular and microbial epidemiology of illness and infection in clinical environments. The study represents foundational environmental evidence from St. Luke’s University Health Network that preceded the full retrospective cohort study published in Surgery in 2020. Published in IntechOpen, March 2019. DOI: 10.5772/intechopen.84530. Authors: Stawicki, S.P.; Brisendine, C.; Levicoff, L.; Ford, F.; Snyder, B.; Eid, S.; Worrilow, K.C.
