Main Study Findings

Author's Conclusions

Lipp and Edwards, 2002 (updated 2012)⁷

2106 patients in three trials – no statistically significant differences found

Postoperative Wound Infections – Clean Surgery Only
ODR<1 favours SFM
2 quasi-RCTs

ODR(95%CI): 1.34 (0.58, 3.07)
ODR(95%CI): 0.07 (0.00, 1.63)

1 RCT

ODR(95%CI):1.17 (0.70, 1.97)

“From the limited results, it is unclear whether the wearing of surgical face masks by the surgical team either increases or reduces the risk of surgical site infection in patients undergoing clean surgery.”⁷ (p. 10)

Bahli, 2009¹

8311 patients in three trials

Postoperative Would Infections
2 quasi-RCTs – no statistically significant differences

3.5% without SFM, 4.7% with SFM
30% without SFM, 0% with SFM

1 PCS – statistical significance favouring no SFMs

1.8% without SFM, 4.4% with SFM (P<0.05)

“Evidence regarding effectiveness of surgical facemasks in preventing postoperative wound infection in elective surgery is inconclusive. It is difficult to alter current clinical practice of wearing facemasks in theatres on the basis of current evidence.”¹ (p. 170)
