Abstract
OBJECTIVE:
To assess expert knowledge, perceptions, and experience on the role of the built environment in the acquisition and transmission of healthcare-associated infections (HAIs), facility design decision-making considerations, and strategies for intervention through facility design and technologies.
BACKGROUND:
Healthcare-associated infections pose a serious and costly threat to public health in the United States. A growing evidence base suggests that the built environment can play a role in interrupting the chain of infection.
METHODS:
Semi-structured individual interviews and triads were conducted with 26 experts in hospital administration, architecture, interior design, infection control, and air and water quality. A grounded theory approach was used for interview coding and interpretation.
RESULTS:
Participants characterized the shift in thinking about the relationship between the built environment and HAI transmission as a “progression,” as accountability for infection prevention has expanded beyond clinicians. Organizational leaders aim to make informed design decisions, but this can be challenging due to the paucity of efficacy and return on investment data. Emerging interventions include copper impregnated materials, seamless flooring, and chilled beams.
CONCLUSIONS:
No single intervention is entirely effective in mitigating HAI risk; multiple interventions are needed. In addition to the built environment, human behavior must be considered, as noncompliance can render even the best designs ineffective. Increased multidisciplinary collaboration is needed to improve the application of evidence and experience in healthcare facility design. In the absence of conclusive evidence regarding interventions aimed at reducing HAI transmission, a combination of research data and practical experience should be used to inform design decisions.
