Figure 2. Incidence of Surgical Site Infection (SSI) and Noninfectious Wound Complications (NIWCs) After Secondary Reconstruction (SR) Stratified by SSI and NIWC After Immediate Implant Reconstruction .

^aSSIs attributable to the immediate implant reconstruction (implant IR) were identified within 90 days of the index procedure. Follow-up to identify SR was performed through 365 days after mastectomy.

^bIndicates attributable to implant IR.

^cOf these, 273 (39.9%) did not have a secondary reconstructive procedure within 365 days of the index surgery.

^dExcludes 9 women with an SSI or cellulitis within 30 days before SR, not attributable to implant IR.

^eIf we included the 105 women with SSI more than 90 days after implant IR who had SR in the uninfected category, an additional 8 women had an SSI and 6 women had an NIWC after SR, bringing the total number of SSIs attributable to SR to 139 (2.9%) and the total number of NIWCs attributable to SR to 126 (2.6%). Compared with the incidence of SSI and NIWCs for women who had SSI within 90 days after implant IR, the differences remain statistically significant (P < .001).

^fNIWCs attributable to the immediate implant reconstruction were identified within 90 days of the index procedure. Follow-up to identify SR was performed through 365 days after mastectomy.

^gIndicates attributable to implant IR.

^hIf we included the 79 women with NIWCs more than 90 days after implant IR who had SR into the uncomplicated category, an additional 2 women had an SSI and 3 women had an NIWC after SR, bringing the total number of SSIs attributable to SR to 144 (3.0%) and the total number of NIWCs attributable to SR to 116 (2.4%). Compared with the incidence of SSI and NIWCs for women who had NIWCs within 90 days after implant IR, the differences remain statistically significant (P < .001).
