Are skull caps superior to surgical bouffant caps? Here are the facts.
At any time the skin is violated, there is the possibility of infection. Cosmetic surgeons, certainly, have actually known this since they began taking sharp objects to the skin, either to eliminate arm or legs or organs or reposition anatomy for healing intent. We also know that the danger of a surgical site infection (SSI) varies relying on the procedure. Today that expertise is codified right into surgical injury categories:
Clean: These surgical injuries are uninfected and also without preexisting swelling, and systems where germs might stay (e.g., respiratory system, GI, GU systems) are not gone into. These wounds are closed mainly; i.e., stapled or stitched closed at the end of the treatment. Instances: Removal of skin lesions, mastectomy, thyroid surgical procedure, rupture repair service, splenectomy.
Clean-contaminated: These are injuries in procedures in which the breathing, GI, or GU system is gone into, but in a planned, controlled fashion. There is no unusual contamination with the materials of those systems, since they are gone into in a controlled style as well as contamination is minimized. Instances: Cholecystectomy, tiny digestive tract resection, Whipple procedure, gastric surgery, lung surgical treatment, colon surgery.
Infected: These injuries occur in situations such as taking care of open, fresh unexpected wounds; instances in which there is a major break in clean and sterile technique, gross spillage from the GI system or acute nonpurulent (no pus) swelling.
Dirty: “Dirty situations” are, as you might think of, quite filthy. They include, as an example, old stressful injuries with debilitated tissue from an automobile accident; existing bowel opening, infection, and even gross abscess. The factor is that the gross contamination and organisms exist before the treatment begins. Instances: Incision and also drainage of an abscess, repair of a perforated digestive tract, peritonitis, wound debridement, and so on.
The greater the medical course, in general, the greater the risk of a postoperative wound infection. Or two surgical dogma has generally educated (a lot more on that particular later).
Additionally, in general, preoperative anti-biotics are carried out before situations that are course 2 (clean-contaminated) or above, and key closure of the skin is usually not advised for class 3 (infected) as well as over. As holds true of a lot of stuff in medicine, the policies are not necessarily hard and fast, yet this is the straightforward version taught to medical students. Additionally, establishing what does and also does not work in regards to avoiding SSIs has actually turned out to be not as simple as one would certainly assume. There’s a lot of conviction here, and recommendations have actually transformed throughout the years.
SSIs, not surprisingly, has become a focus of high-quality improvement, with fantastic initiative, particularly by the American College of Surgeons’ National Surgical Quality Improvement Program (ACS NSQIP ®). I would certainly such as to concentrate on simply one conflict that’s been making over the last couple of years that (lastly, I wish) has most likely been dealt with and in doing so have what I wish to be an enjoyable modification of speed from my normal tirades. So today I will be talking about a relatively focused topic as well as major research that was just published in the August issue of the Journal of the American College of Surgeons resolving a crucial inquiry: Bouffant vs Skull Cap as well as Impact on Surgical Site Infection: Does Operating Room Headwear Really Matter? In other words, does the option of headgear to maintain that nasty hair of your own far from the medical field matter? (Spoilers: It does not.) Prior to we reach the study, let’s take a look at the discussion as well as its history.
Skullcap versus bouffant?
Any person that’s remained in the operating room (or enjoyed clinical dramas on tv) is most likely conscious that surgical headgear can be found in 2 types: the skullcap or the bouffant. The skullcap normally resembles this:
Skull caps are what the amazing specialists all wear, right?
As you can see, it’s limited and also lean and actually relatively good-looking. Certainly, here’s a selfie I took a few years earlier, before my health center removed the medical skullcap (and before I grew my present beard):.
Dr, David Gorski: Ready for action.
Tolerable, if I do say so myself. I nearly resemble an actual cosmetic surgeon in this photo.
After that there’s the bouffant cap. You can really see one aware above, yet the head of the woman who’s using it is partially covered by the surgeon putting on the skullcap. Below’s another specialist putting on a bouffant cap:.
If you don’t select a bouffant cap, you’re most likely to be giving your people nasty infections, approximately AORN appears to be claiming.
As you can see, it’s primarily a much looser-fitting cap with flexible to maintain it on the head. The majority of older doctors, specifically male cosmetic surgeons, also dislike it.
Throughout my virtually 30 years as a surgeon (if you count my residency), I’ve utilized both selections of caps. I tend to favor the skullcap since it’s better-fitting for someone with brief hair, as well as the bouffant cap has a tendency to migrate on my head as I move around doing procedures. The one disadvantage to the skullcap is that it squashes my hair to the factor that, when I return after a day in the operating area, my other half occasionally teases my “operation head”.
Why, you might ask, should anybody care about this? If you don’t work in an operating room, there’s most likely no great factor to care. Among those people who do, the issue has actually become, instead unusually, a pretty passionate argument. For instance, take a look at this write-up from 2 years back in the Boston Globe:.
Doctors for many years have stepped into operating rooms using their surgical cap– a snug covering that ties in back and also is available in standard-issue blue or numerous personalized designs.
Yet a suppression seems underway on that nearly spiritual item of headgear.
Assessors in January reprimanded running area personnel at Brigham and Women’s Hospital in Boston for having the hair around their ears revealed throughout surgical procedure– as well as for sporting visible facial hair. As Well As a New York surgeon was written for revealing 3 inches of hair at the neck of his neck.
Without a doubt, various other operating space team wear surgical caps, however, they have actually long been the hat of selection for lots of surgeons. The trouble is the hats typically leave percentages of hair as well as the ears subjected– a circumstance that an influential nursing team says could promote infection.
Regulatory authorities have taken the nurses’ problems to heart, compelling some healthcare facilities to switch over to bath cap-like “bouffants,” which can be pulled down over a user’s entire head.
To be honest, I’ve never actually utilized a towel skull cap in the operating space, as well as whenever I’ve seen a specialist sporting one I constantly wondered when the last time it had actually been washed was. If such a cap, regardless of just how spiffy the layout, hasn’t been washed after every one or more days of use, directly I couldn’t help however think: Ew. So rather, I used the nonreusable paper caps.
Primarily, what we’re checking out here is a recurring spat in between the Association of periOperative Registered Nurses (AORN) and specialists, represented by the American College of Surgeons. AORN standards in technique restriction the skull cap and also require the bouffant cap, while ACS standards mention that skull caps with very little hair direct exposure serve. Why do I say the AORN guidelines prohibit the skull cap “in practice”? Continue reading as well as figure out.
This is what the battle in between skull caps as well as bouffant caps is beginning to appear like.
Cage match: ACS vs. AORN.
To be straightforward, I’ve rarely seen a tiff between 2 professional organizations over a medical standard based upon so little evidence and also instilled with much feeling. Checking out each side’s placement declarations while composing this message, I had a hard time not ending, “A pox on both your homes”. (I understand that some doctors will likely watch me as a traitor or apostate for stating that. Such is life.) Regardless, let’s consider the ACS reaction to AORN’s standards.
First, it is amazing just how much wide agreement there was between the two organizations. On the various other hand, I was a little bit ashamed at exactly how the ACS mentioned that its “guidelines for appropriate outfit are based on professionalism and trust, sound judgment, decorum, as well as the available evidence”. Why is evidence listed last? And also who appreciates sound judgment? Nevertheless, here are the areas of basic agreement, besides some quibbling around the sides, which I won’t go over carefully:
- Soiled scrubs and/or hats ought to be altered as quickly as feasible and also absolutely before consulting with relative after a surgery.
- Scrubs and hats put on throughout unclean or contaminated instances must be altered prior to subsequent instances even if not visibly stained.
- Masks ought to not be worn hanging at any moment.Running space (OR) scrubs must not be worn in the health center facility outside of the OR location without a clean laboratory coat or proper hide over them.
- OR scrubs must not be used at any moment outside of the health center perimeter.
- OR scrubs need to be changed at least daily.
- During intrusive treatments, the mouth, nose, and also hair (skull and face) need to be covered to stay clear of prospective wound contamination. Big sideburns as well as ponytails must be covered or consisted of. There is no proof that leaving ears, a minimal amount of hair on the nape of the neck or
- a moderate sideburn exposed adds to wound infections.
- Jewelry and fashion jewelry worn on the head or neck where they might come under or pollute the sterilized area should all be eliminated or appropriately covered during procedures.
- The ACS encourages tidy proper expert attire (not scrubs) to be worn throughout all individual experiences beyond the OR.
- Currently right here’s an additional twist. The ACS action specified:.
The skullcap is symbolic of the medical occupation. The skullcap can be put on when near to the completeness of hair is covered by it and only a minimal quantity of hair on the neck of the neck or a small sideburn continues to be uncovered. Like OR scrubs, cloth head caps need to be cleansed as well as transformed daily. Paper skull caps should be gotten rid of daily and also following every filthy or polluted instance. Religious beliefs regarding headwear must be appreciated without compromising patient safety.
Indeed, among surgeons, much is made in this debate about how the skull cap is probably the “symbol” of the medical career, and perhaps it is– or was, a minimum of when almost all specialists were guys with brief hair. These days, an enhancing percent of doctors are ladies, a lot of whom probably have longer hair as well as can not use a head cap because it doesn’t cover their hair adequately. To argue in 2016 that the skull cap is the “symbol” of the medical profession exposed a blindness to the reality of surgical treatment today. Perhaps the head cap was once the “symbol” of the surgical occupation, yet I would argue that, also if that was once the situation, it should not be any longer.
Stay with the evidence and not some psychological add-on to the days of yore, when males were males and females, mostly, were not surgeons. Also, most of the people in the operating space are not surgeons. There are registered nurses, scrub techs, anesthesiologists, nurse anesthetists, and so on. They probably do not care if the head cap is a “symbol” of the surgical occupation. Yes, we specialists tend to think we’re the facility of deep space.
Undoubtedly, all too often the doctors’ debate basically comes down to “I like it as well as have actually been doing it by doing this for 20 years,” also if the surgeon needs to extend quite a bit to make reasons that boil down to, “I don’t such as bouffant caps” seem like something else:.
None of that is to claim that the AORN placement, at the very least with respect to surgical caps, is especially evidence-based. (Unfortunately, you need to be a member of AORN to see the real declaration on the AORN web site. WTF, AORN?) Take a look at its feedback to the ACS standards, specifically the part where it responds to the statement concerning just how the skull cap is symbolic of the medical occupation.
Putting on a particular head covering based upon its symbolism is not evidence-based, as well as ought to not be a basis for an across the country method suggestion. Numerous kinds of proof exist that assistance referrals that perioperative workers cover their head and ears in the OR. This evidence includes the reality that human skin, as well as hair, is naturally colonized with numerous microorganisms, as well as perioperative employees dropped microorganisms right into the air around them. We know air-borne germs in the OR can fall under the operative area, add to the general air contamination of the OR, as well as place patients in danger of medical website infections. Completely covering the hair can minimize the number of bacteria presented right into OR air by perioperative employees.
I ‘d state that the ACS needs an icepack for that melt, compounded by AORN’s various other retort that, “up until an evidence-based definition of ‘limited’ or ‘small’ can be figured out [d], there is no chance for facilities to apply such a suggestion” that only “restricted” hair can be left exposed.
Nevertheless, in spite of invoking “evidence-based” definitions, notice that AORN really did not point out any kind of real … oh, you recognize … proof to reveal that wearing medical head caps is related to an increased SSI price. It makes a not unreasonable argument in regards to just how the skin as well as hair are colonized with germs and just how surgical workers can lose them. Nonetheless, that’s a disagreement that practically depends on previous likelihood.
Yes, it’s not unreasonable to mention that exposed hair may drop microorganisms onto the surgical field. Nevertheless, cosmetic surgeons used to do a lot of things to decrease SSI rates based upon suggestions that appeared to make good sense at the time however were later found in controlled research studies either to make no distinction or to be counterproductive. Comprehensive shaving of the medical website, specifically the evening previously, enters your mind. Nowadays, we do not cut surgical websites unless there’s a lot of hair, and afterward we only just utilize clippers to cut it really short ideal before surgical procedure, right before the surgical preparation with an antiseptic option.
There was at the time of AORN’s referrals generally no proof recommending that choice of medical headwear affects SSI rates. Also the Boston Globe tale noted that 2 large testimonials of released studies in the last five years before 2016 showed little or no proof that doctor surgical headgear selection influenced SSI prices. It likewise noted AORN’s argument that there can not be any type of randomized regulated trials because such a test “would potentially reveal patients to the risk of infection from health care workers whose skin and also hair were uncovered …” I concur that such a study would be unwise, but not for that factor.
There is what I would call genuine medical equipoise in the concern; we truthfully didn’t know if headgear made a distinction in SSI rates and also the proof to that factor suggested that it probably did not. AORN was method off-base in declaring that such a trial would certainly be dishonest because of absence of scientific equipoise. The genuine reason it would certainly be unwise is due to the fact that no one would certainly wish to agree to be randomized to one sort of cap or an additional. Logistically, such a research would certainly be a nightmare.
Let’s come back to the trouble. In practice, the AORN guidelines for medical attire have caused the outlawing of making use of medical head caps. Why do I say “in practice”? The reason is straightforward. AORN’s suggestions have actually been, basically, adopted by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO), the company that recognizes health centers in the US, and also the Agency for Healthcare Research and also Quality (AHRQ), the U.S. Department of Health and Human Services firm committed to research study and also evidence-based standards to improve the safety and top quality of health care. Keep in mind that tale above? Who were the assessors that mentioned the health centers for violations of surgical headgear standards? JCAHO. Therefore:.
After it familiarized the raised examination, Beth Israel Deaconess Medical Center in Boston removed doctors’ conventional scrub hats. Dr. Daniel Jones now wears a bouffant pulled down over his ears– but he’s not thrilled about it. “Doubt the ear hairs pose any type of risk,” he said in an email. “Some in fact put on a scrub hat under the bouffant to dress it up.”.
And that’s what’s taking place all over the nation. The OR leadership in my very own hospital stated that skull caps would no longer be permitted, once more, based upon no evidence.
Amusingly, AORN is a little bit annoyed at this entire conflict. Certainly, last year, it provided a declaration denying that its guidelines outlaw using head caps. It explained that the 2014 guidelines mentioned, “A tidy medical head cover or hood that confines all hair as well as completely covers the ears, scalp skin, sideburns, and also nape of the neck ought to be put on.” AORN bases this referral on the observation that hair can nurture germs that can possibly fall under the surgical area. Certainly, AORN took wonderful umbrage at the idea that it has actually “prohibited head caps” in its declaration, lamenting how its setting had actually been “misrepresented” in media reports. If this PowerPoint discussion on the official AORN design template on getting rid of the skull cap as well as supporting for bouffant caps rather is any kind of indicator, AORN was most certainly advocating for eliminating the head cap.
Now, readers who aren’t regulars and don’t value my tendency in the direction of preference to preach on the background of a problem before reaching the research present are most likely annoyed that I haven’t specified yet. So here we go, allow’s reach it: “Bouffant vs Skull Cap and Impact on Surgical Site Infection: Does Operating Room Headwear Really Matter?”.
The authors note in the intro the aspects connected with enhanced risk of SSI:.
Roughly 300,000 medical website infections (SSIs) happen yearly, representing around one-third of hospital-acquired infections.1, 2, 3 Many elements add to this, consisting of surgery kind, glucose control, and client body temperature level. Current interest has been offered to the sort of headwear as a threat variable for SSIs. Little study is available on the efficacy of different head covers in lowering the occurrence of SSIs. Regardless of the lack of clear evidence, there is a continuous difference over which kind of head cover should be recommended in the perioperative setting.
The American College of Surgeons standards indicate that skull caps with marginal hair direct exposure are acceptable, and the Association of Perioperative Registered Nurses recommends bouffant caps with insurance coverage of all hair. Furthermore, they suggest covering the ears, sideburns, scalp, and nape of the neck, on the basis that hair and also skin in these sites are known to harbor germs that can be spread.4, 5, 6, 7 However, no clinical evidence has revealed a considerable benefit in SSI decrease with either cap. This study aimed to figure out the impact of medical cap selection on SSI prices by comparing the incidence of SSIs based upon going to specialists’ use skull caps or bouffant caps in the perioperative setting.
So just how did the investigators, led by matching writer Shanu N. Kothari, MD at the Gundersen Health System in La Cross, WI, method this trouble? Generally by reanalyzing information from a big randomized regulated test that considered whether clipping hair at the surgical site influenced SSI prices. (It didn’t, incidentally. The only factor we often tend to clip hair these days is for benefit when there’s a great deal of it.) Primarily, information from this randomized research study were re-analyzed to identify the effect of cosmetic surgeon choice for bouffant vs skull cap, despite whether hair was clipped or left undamaged. In brief, patients were grouped based upon the participating in doctors’ headwear, and the main end factor was SSI observed. Additional variables consisted of preoperative comorbidities, personnel approach, and also procedure type.
In general, there were 1,543 clients in the analysis, with participating in doctors using bouffant caps in 39% of the situations as well as head caps in 61% of the cases. The authors found that individuals whose cosmetic surgeons wore a bouffant cap had a tendency to be somewhat older, have a lower BMI, as well as were going through primarily hernia/other treatments. 6 people in both the bouffant and head cap teams had a history of colonization with methicillin-resistant Staphylococcus aureus (MRSA). Use perioperative antibiotics coincided in both groups. The raw numbers revealed that SSIs were observed in 96 (6.2%) of individuals, with 8.1% in the bouffant group and also 5.0% in the skull cap team. Nonetheless, after changing for the sort of procedure and also surgical approach in a multivariate logistic regression design, no distinction in SSI rates for head cap versus bouffant cap was spotted.
This research study has a lot of strengths. It was pretty big, with over 1,500 people, and also, since the research study being reanalyzed was research clearly designed to check out SSI rates in between control and also experimental group, the analysis criteria for SSI medical diagnosis were standardized and also extensive. Naturally, its key constraint is that it is an article hoc analysis of an existing RCT dataset checking out a variable not included in the previous design. The writers likewise noted:.
The previous research data were biased toward male people, as additional criteria consisted of sufficient body hair to warrant hair clipping. Specialist cap choice was related to their specialized and procedure kinds. For instance, the substantial bulk of foregut cases were carried out by surgeons that chose head caps. In addition, although the head covering of the participating in specialist was understood, we did not record the head treatments that participants of the medical team wore. Additionally, the research was conducted in the setup of elective general surgical procedures as well as omitted vascular, anorectal, orthopedic, obstetric, and also gynecologic treatments. Analysis of cap product, including actions of pore dimension and comparison orbit counts, along with quantifying microbial sedimentation price, were beyond the extent of this research study.
Despite those constraints, when absorbed the context of the evidence base existing prior to this research was performed, these data are yet one more solid piece of proof that choice of medical headgear likely does not matter and also doesn’t effect SSI rates. As the authors keep in mind, this follows what we understood previously, and this study isn’t alone. For example, a large retrospective research study by Shallwani et alia fell short to discover a statistically significant modification in the SSI price from 13 months before to 13 months after the new AORN plans.
Custom versus proof in the operating room
One aspect of the research above that led me for more information about this concern is a recent magazine by Bartek et al, “Naked Surgeons? The Debate About What to Wear in the Operating Room”, which was cited by the writers. This certain viewpoint item with targeted literature testimonial pointed out how steeped in practice, as opposed to proof, a lot of infection control procedures in the operating area are as well as how heterogeneous and contrasting the proof is for a number of them. It’s a fascinating read and also appears not to be behind a paywall; I suggest it.
Here’s an example that my UK coworkers could value. It’s another AORN guideline that greatly varies from the referrals in the UK, specifically the referral by AORN that all OR personnel keep their arms covered, amusingly under the subject of “The Right To Bare Arms”:
On the topic of covering the arms, AORN advises: “When in the limited locations, all nonscrubbed employees ought to entirely cover their arms with a long-sleeved scrub top or coat”  Remarkably, AORN’s referrals and also the United Kingdom’s NICE’s requirements are inconsistent: As above, AORN advises using a “long-sleeved scrub top or coat,” whereas NICE’s plan is “bare listed below the arm joints” [1, 22] The reality that 2 huge, guideline-producing bodies would certainly recommend totally opposing methods under the rubric of evidence-based medicine is questionable.
Old research studies checking out air-borne bacteria reveal, to name a few points, that ladies using stockings dropped much more bacteria than women with bare legs  NICE took the stance that handwashing is what is key and apparel with sleeves does not impact microbial swarm counts, but that it can affect practitioners’ abilities to clean their hands. This verdict as well has been refuted 
Perhaps several of my British associates that review this blog could chip in the remarks, however, I must admit that I was entertained by this debate.
Bartek et alia additionally note that, the, even more, we dive into the question of microbial losing from people’s skin, the murkier things obtain. For example, they keep in mind that guys dropped twice as lots of germs as women, but no one has actually ever promoted for a constraint on men in the operating area. They additionally keep in mind that the release of bacteria from scrubs and also street clothing was studied as well as located to be roughly equal, yet scrubs continue to be basic and street clothes are prohibited in the OR. Based upon the previous searchings for, if decreasing SSIs is your objective there’s no actual reason not to allow specialists ahead right into the OR in their street garments as well as to gown up over them, the very means doctors were depicted as performing in one of my favorite clinical dramatization of perpetuity, The Knick.
I additionally note that the doctors in the year 1900 represented on The Knick also ran without gloves. (The putting on of sterilized medical gloves by cosmetic surgeons as well as anybody that can touch the operative field is one of minority points that have actually been definitively revealed to lower SSI prices, a finding first reported by a protégé of William Stewart Halsted in 1899, a year prior to the fictional events depicted in the first period of The Knick.).
Maybe the most entertaining monitoring was this:
Another collection of researches reached a much more radical verdict: Naked males shed around a third to a half as several germs as the same guys using road clothing or scrub fits [27, 28] Perhaps “scrubs” actually meet their name: rather than “capturing” squames, which the skin sheds constantly, they might in fact be “rubbing” these bacteria-laden squames from our skin. If we are to abide by the stringent prescription of evidence-based medicine, ought we to disrobe before access into the operating area? We say no, although for reasons that are outside of just how it would affect microbial matters in the operating area.
Does that state there’s no room for it in peer-reviewed clinical literature?
There are other usual methods that truly do not have a strong proof base for them. (Some would also argue that the medical site classification is doing not have in that respect.) As an example, there is no evidence that using surgical masks avoids SSIs. Without a doubt, there’s even a Cochrane review that suggests or else, and also Bartek et alia mention that masks have actually never ever been shown to be reliable in stopping SSIs.
Nevertheless, if your function is to safeguard the specialist as well as others working with the client from being splashed with blood in the mouth or nose, after that requiring a surgical mask makes ideal sense, equally as calling for safety glasses does. That’s likely why no person is proposing that we cosmetic surgeons stop using them. Definitely, as a person that’s been splashed in the confront with blood many times for many years (although much less frequently as well as with much less quantity ever since I limited my method to bust surgical procedure), I’m earned out by the idea of running without a mask.

The lower line is that, although the reaction of specialists and also the ACS to the AORN recommendation struck me as rooted even more in emotion and also practice than anything else, the ACS did have a factor. There was no proof that the option of headgear has a substantial effect on SSI prices, as well as there is no evidence that it does.
In its feedback to the AORN standards, ACS would certainly have been better served by ditching the bit concerning the head cap being a “symbol” of the surgical occupation, which struck me as a callback to our more-than-a-bit sexist past, and also adhering to the proof. In a similar way, AORN would certainly have done well not to overreach as well as extrapolate beyond what the evidence warranted in its referrals. Ultimately, I can not aid but end that this entire kerfuffle was an example of exactly how the tiniest disputes all frequently result in one of the most protracted battles.
