Skull Cap or Bouffant Cap: Why It Matters

In 2014, the Association of periOperative Registered Nurses (AORN) published guidelines on operating room attire. The guidelines stated: “A bouffant hat should be worn to cover all of the hair, scalp, and ears to minimize skin and hair shedding and protect surgical patients from bacteria.”1 A related article from the AORN stated to: “prohibit personnel from wearing skull caps altogether unless they are completely covered by a bouffant hat.”2 The guidelines also stated that health care providers’ arms should be covered with long-sleeve apparel while in the OR.

What followed was a de facto prohibition on skull caps. Virtually overnight, OR managers across the United States removed skull caps from locker rooms, forbade personal skull caps made of cloth, and mandated the use of jackets within the OR areas. Surgeons and anesthesiologists were caught off guard and became upset as these top-down mandates were suddenly implemented with little or no physician input. The medical community was doubly frustrated to find that these guidelines were not based on rigorous scientific evidence, but rather “a number of studies showing that hair can be a source of bacterial organisms and potential surgical site infection.”3

Surgical attire mandates were quickly incorporated into local hospital policies and Joint Commission surveys, facilitated by AORN guidelines which provided OR managers with ready language.

The American Society of Anesthesiologists (ASA), for its part, assembled a working group in response to the AORN guidelines and actively met with the ACS, AORN and other stakeholders to ensure that anesthesiologists’ voices were heard and that future guidelines would be based on medical science.
Fast forward to the present. The AORN recently released updated guidelines for surgical attire. Perhaps in response to recent studies and the input from the ASA and ACS, the AORN appears to have backtracked on the more contentious points in the previous guidelines. The new proposed guidelines state that “no recommendation can be made” regarding head covers, clothing underneath scrubs, and arm coverage; decision making is largely deferred to the local institution. To its credit, the AORN held a 60-day open comment period which closed on Feb. 22, 2019, and more than 200 comments were submitted. Final guidelines are scheduled to be published this summer.

The debate over surgical attire raises troubling questions regarding the roles of societies and individuals working in health care, the promulgation of policies, and the level of scientific evidence behind these policies. What is the authority of AORN, and how did its guidelines come to have such widespread influence? Why did the Joint Commission include the AORN surgical attire guidelines in its surveys with little or no physician input? How many other Joint Commission standards have dubious scientific justification? What other latent opportunities exist for nonphysicians to influence physician practice?

Prior to this episode, many physicians would have deemed a study of OR head covering an amusing sideshow—perhaps even a waste of time—but this controversy demonstrates that any issue, no matter how trivial, can become an opportunity for nonphysicians and regulators to influence physician practice. Only by taking proactive ownership of all things in the perioperative arena can we ensure that policies are held to the same “burden of proof” as our clinical practices. Ample opportunities exist for us to establish medical evidence and best practices in scientific, regulatory and policy areas. If we don’t do it, others will do it for us.

“As Director of Surgical Services Departments there has been considerable changes have occurred in my department and Anesthesia Experts has always risen to meet our demands of our facility. They have been very pro-active in meeting the increase volumes allowing us to keep our surgeons and patients very satisfied with our services.”

AR BSN 346 beds AL   

“Before AE took over the anesthesia department was described by the surgeons as the worst in the history of our hospital. The prior management company was having a cancelled surgery per day. I am happy to report there has not been one since they have taken over the department. Additionally we have seen a 905 reduction if requested preop
lab tests. The anesthesia department is now the very best hospital department in our entire facility.”

DS CEO 272 beds MS   

“Anesthesia Experts has provided consistent anesthesia providers who display a high degree of integrity, responsibility and professionalism. They have become a more valuable part of our facility and community.”

LR CEO 150 beds TX   

“Even though they are physically located 1000 miles away Anesthesia Experts just does not provide great anesthesia coverage they personally engage surgeons to increase their business. Last year my surgical volume rose by 24% and we are currently 50% ahead of last year and all of that growth is organic.”

JE FACHE CEO AL 92 bed hospital   

“Anesthesia Experts is more responsive than anyone I have dealt with. They are available by phone whenever needed and will be on site for any need or request and has been on site to address issues before we can make the request.”

SW CEO 25 beds NM   

“While problems are extremely rare when they do occur Anesthesia Experts quickly and professionally implements a solution. Our surgical volume has grown over 100 cases per month and now our GI docs want to perform all of their endoscopies in our hospital instead of their GI lab that they own!”

SP CEO 346 beds AL   

“Our anesthesia department was a thorn in my side that kept me awake at night. Anesthesia Experts swept in and brought order to our mess and our department was quickly redirected.”
