The (Sterile) Gloves Are Coming Off
Your practice manager, on a quest to reduce expenses, asks whether your practice could reduce the amount of money spent on gloves for procedures. How do you reply?
The effect of a small difference spread over a large number of events can be sizable. For example, the added cost of using sterile, as opposed to nonsterile, gloves for minor procedures is relatively modest and certainly worthwhile if the sterile gloves reduce the number of surgical site infections (SSIs). However, if there is no difference in SSIs, the extra cost becomes a large unnecessary expense, given the volume of minor procedures performed.
The decision to use sterile gloves often stems from habit, product availability, or perceived benefit of fewer SSIs.2 Providers’ choice of gloves varies widely, despite some evidence comparing sterile and nonsterile gloves.3-5
STUDY SUMMARY
Sterile no better than nonsterile gloves
This systematic review and meta-analysis of 13 RCTs and observational (prospective or retrospective) studies compared infection rates using sterile versus nonsterile gloves in 11,071 unique patients. The methods used in the review followed the Cochrane collaboration guidelines.6 Patients included in each study underwent outpatient cutaneous or mucosal surgical procedures, including laceration repair, standard excisions, Mohs micrographic surgery, or tooth extractions. In addition to glove type, documentation of postoperative SSI was necessary for inclusion.
Methodology. A total of 512 publications were reviewed for inclusion; 14 met the criteria but one study was removed due to incomplete data, leaving 13 trials with a total of 11,071 patients for the analysis. In the RCTs, 1,360 patients were randomly assigned to treatment with sterile gloves and 1,381 to treatment with nonsterile gloves as the intervention. In the prospective or retrospective observational trials, 4,680 patients were treated with sterile gloves, and 3,650 were treated with nonsterile gloves. Heterogeneity was low. Of note, the researchers performed a subgroup analysis on nine studies (4 RCTs and 5 observational studies) involving only cutaneous surgeries; these represented procedures most likely performed in the primary care setting.
The primary outcome of this review was postoperative wound infection. The results did not show any difference in SSIs between sterile and nonsterile gloves in all trials (2% vs 2.1%; relative risk [RR], 1.06). There was also no difference in infection rate in the subgroup analysis (2.2% vs 2.2%, respectively; RR, 1.02) or an analysis limited to only RCTs.
WHAT’S NEW
Highest-quality evidence shows no difference
This systematic review found no difference in SSI rates when using sterile versus nonsterile gloves. Given that the analysis represents the highest-quality level of evidence (a systematic review of RCTs) and that sterile gloves are several times more expensive per pair than nonsterile gloves, the findings should impact future practice.

Risk for bias and limited applicability
Not every trial in this meta-analysis was an RCT, and the inclusion of observational studies increases the risk for bias. However, the results of the observational studies were similar to those of the RCTs, somewhat alleviating this potential threat to validity.
It is worth noting that more extensive surgeries and more complicated repairs were not included in the trials, meaning that the findings are limited to oral surgery, Mohs micrographic surgery, standard incisions, and laceration repairs.
CHALLENGES TO IMPLEMENTATION
Inertia, medicolegal concerns, and personal preference
Clinical inertia may lead to slow adoption of these recommendations. Providers may worry about potential medicolegal ramifications from this change.1 Lastly, some providers may prefer the fit and feel of sterile gloves for their procedures.

Time to switch to nonsterile gloves for these procedures?
ILLUSTRATIVE CASE
Your practice manager comes to you to discuss ways that you can reduce expenses. He asks whether the practice could reduce the amount of money spent on gloves for procedures. How do you reply?
A decision involving a small difference, spread over a larger number of events, can have a sizable effect. An example is whether to use sterile vs nonsterile gloves for minor procedures. The cost difference between a box of sterile gloves and a box of nonsterile gloves is relatively small, and certainly worth the difference if the more expensive sterile gloves reduce the number of surgical site infections (SSIs).
However, if there is no difference in the number of SSIs, there may be no value to the extra cost, which, given the number of such procedures, becomes a large unnecessary expense. The choice to use sterile gloves often stems from habit, product availability, or the perceived benefit of fewer SSIs.2 While some evidence exists comparing glove choice, there is wide variability in physicians’ choice of gloves.3-5 This large systematic review compared rates of SSIs using sterile vs nonsterile gloves.
STUDY SUMMARY
RCTs/observational studies find sterile no better than nonsterile gloves
This systematic review and meta-analysis of 13 randomized controlled trials (RCTs) and observational (prospective or retrospective) studies compared infection rates using sterile vs nonsterile gloves in 11,071 unique patients undergoing cutaneous surgery, including Mohs microsurgery or outpatient dental procedures. The methods used in the review followed the Cochrane collaboration guidelines.6 The inclusion criteria were that the studies had to be either RCTs or observational studies. Patients included in each study underwent outpatient cutaneous or mucosal surgical procedures, including laceration repair, standard excisions, Mohs micrographic surgery, or tooth extractions. In addition to glove type, documentation of postoperative SSI was necessary for inclusion.
Methodology. The authors of the analysis reviewed a total of 512 publications for inclusion; of these, 14 met the inclusion criteria. One study was later removed due to incomplete data, leaving a total of 13 trials for the analysis. Of the 11,071 patients included in the final analysis, 1360 patients were randomly assigned to treatment with sterile gloves, while 1381 patients were assigned to treatment with nonsterile gloves as the intervention in a clinical trial. The remaining patients participated in either prospective or retrospective observational trials; 4680 patients were treated with sterile gloves, and 3650 patients were treated with nonsterile gloves. Heterogeneity was low for the included studies. Of note, the researchers performed a subgroup analysis on 9 total studies (4 RCTs and 5 observational studies) involving cutaneous surgeries only. These represented procedures most likely performed in the primary care setting.
The primary outcome of this review was postoperative wound infection. The results did not show any difference in SSIs between sterile vs nonsterile gloves in all trials (2% vs 2.1%; relative risk [RR]=1.06; 95% confidence interval [CI], 0.81-1.39). There was also no difference in infection rates in the subgroup analysis of 9 trials limited to cutaneous surgery (2.2% vs 2.2%, respectively; RR=1.02; 95% CI, 0.78-1.34) or when the analysis was limited to only RCTs.
