Insufficient evidence to link forced-air, SSI increase
Independent, nonprofit research organization publishes guidance following literature review: "does not believe that the currently available evidence justifies discontinuing the use of forced-air warming during surgery."
Independent research organization
"Forced-air is safe, effective, easy to use..."
“Before the development of forced-air warming, there was no good way to keep surgical patients warm. Forced-air is safe, effective, easy to use and inexpensive. It has thus become the most common way of keeping patients warm during surgery.”
Anesthesiologist Dr. Daniel Sessler
"I’m confident in the use of forced-air warming..."
“I’m confident in the use of forced-air warming blankets at my institution for patients undergoing total joint arthroplasty in laminar flow equipped ORs. Normothermia maintenance plays a critical role in minimizing complications following any surgery and should be exercised whenever possible.”
Dr. Javad Parvizi

Benefits

A proven, widely trusted practice

For more than 25 years, forced-air warming has been the gold standard for managing perioperative normothermia in surgical patients worldwide.1-4 Professional organizations such as the Association of periOperative Registered Nurses (AORN), the American Society of Anesthesiologists (ASA) and the American Society of Peri-Anesthesia Nurses (ASPAN), all note the important role of normothermia maintenance in SSI reduction—as do national quality initiatives including those developed by the Institute for Healthcare Improvement (IHI) and the Surgical Care Improvement Project (SCIP). Several of these organizations and initiatives specifically name forced-air warming as a key means of maintaining normothermia.

High-quality randomized trials show that maintaining normothermia may:5

  • Reduce surgical bleeding and the need for blood products
  • Reduce the risk of surgical wound infection
  • Decrease the risk of postoperative myocardial infarction (heart attack)
  • Shorten postoperative recovery and the duration of hospitalization
  • Improve patient comfort
  • Offer a potential savings of $2,500 to $7,000 per patient

FAW FAQs

Your forced-air warming questions…answered

Do convective and conductive warming methods have the same warming efficiency?

Research has shown 3M™ Bair Hugger™ therapy warms patients significantly better than conductive resistive electric-type blankets and mattresses1,2 In fact, one clinical trial showed that a Bair Hugger full body blanket rewarmed patients two times faster than a resistive electric full body blanket.1 In addition, one study found the Bair Hugger full access underbody blanket to be significantly better in reducing post-bypass temperature afterdrop than a resistive heating mattress.2

What types of warming options are available on the marketplace?

From warmed cotton blankets to forced-air warming blankets, a wide array of methods with varying degrees of effectiveness are available to help prevent unintended hypothermia. Active warming modalities included in the current CMS normothermia measure are forced-air warming, conductive warming, warm-water garments and resistive warming.

How should I choose the best warming modality for my facility?

Ultimately, it comes down to a question of what technology will best position the hospital to warm every surgical patient, achieve the guideline goal of perioperative normothermia and even improve patient satisfaction – all in a cost-effective way.

 In order to decide which warming modality is the best fit for a particular facility, there are several key considerations to keep in mind, including:

  • Is it proven?
  • Is it safe?
  • Does it improve outcomes?
  • Does it increase patient satisfaction?
  • Does it help lower costs?
  • Is it easy to implement?
  • Will staff embrace it?

How is patient satisfaction linked to the financial strength of my facility?

Patient satisfaction and the entire care experience are increasingly emphasized in consumer-directed healthcare plans and pay-for-performance reimbursement arrangements. A positive patient experience can become a distinct competitive advantage for a healthcare facility. Research conducted by Press Ganey show a direct correlation between patient satisfaction scores and financial strength. The findings revealed that the higher the patient satisfaction score, the more profitable the hospital.3 High patient satisfaction can set a hospital apart from competition, driving traffic and feeding the revenue stream.

Clearly patient satisfaction is a potent mechanism for increasing and sustaining market share and the bottom line.4 Working to improve patient satisfaction more than pays for itself, 4which is another great reason to comply with SCIP-Inf-10 in an effort to keep patients healthy, and therefore happy.
