Whatís New in the Patient Safety World

HAIís: Costs, WHO Hand Hygiene, etc.

 

 

Healthcare-associated infections (HAIís) have been a major focus of quality improvement and patient safety initiatives as well as pay-for-performance initiatives over the last decade. Recently, a study sought to quantify the financial impact of HAIís (Zimlichman 2013). Many prior publications on the financial impact of HAIís have looked at total costs. The current study looked at costs attributable to the HAIís (that is, costs that would not have been incurred had the HAI not occurred). They found that the average cost for HAIís was as follows:

 

CLABSI (central lineĖassociated bloodstream infections)††††††††† $45,814

VAP (ventilator-associated pneumonia)†††††††††††††††††††††††† $40,144

SSI (surgical site infections)†††††††††††††††††††††††††††††††††††††††††††††††††††††† $20,785

C. diff (Clostridium difficile infection)†††††††††††††††††††††††††††† $11,285

CAUTI (catheter-associated urinary tract infections)††††††††††††††††† $†††† 896

 

Taking into account the frequency of the various HAIís they estimate the total annual costs for the 5 major HAIís to be $9.8 billion, with SSIís and VAP each accounting for almost a third of that.

 

But who is currently footing that bill? In some cases in the current reimbursement world there is actually little incentive to improve. A recent study (Hsu 2013) evaluated the impact of a central lineĖassociated bloodstream infection (CLABSI) initiative on costs, reimbursements, and margins for a hospital and its payers. They concluded that hospitals reduce costs by preventing CLABSIs but also decrease their margins by preventing CLABSIís, creating a perverse incentive.

 

The trend for Medicare and other payors to no longer reimburse hospitals for potentially preventable complications has not yet had a significant impact on HAI rates. However, over the next several years value-based purchasing programs and penalties under the Affordable Care Act will begin to include more weight to HAIís and should serve as an incentive for hospitals to prevent HAIís.

 

One of the interventions usually touted to reduce HAIís is handwashing. There have been a variety of programs designed to improve compliance of healthcare workers with handwashing (see our Patient Safety Tips of the Week for January 5, 2010 ďHowís Your Hand Hygiene?Ē and May 24, 2011 ďHand Hygiene ResourcesĒ). One of the more widely known initiatives has been that espoused by the World Health Organization (WHO). Recently results of a study on the WHO hand hygiene program at six pilot sites in Costa Rica, Italy, Mali, Pakistan, and Saudi Arabia was published (Allegranzi 2013). Implementation had a major effect on compliance of health-care workers across all sites and healthcare workersí knowledge of microbial transmission and hand hygiene principles improved as well. The positive results have been sustained over time. However, what is still missing is data on the actual impact of these improvements on the rates of various HAIís.
