In Depth

Common HAIs include surgical-site infections and C. difficile, many linked to surfaces in the patient environment. Rigorous cleaning and disinfection of high-touch surfaces measurably reduce HAI transmission.

Why It Matters

HAIs harm patients and carry major financial and reputational costs for providers. Environmental cleaning is one of the most cost-effective levers for reducing them.
