In order to investigate the potential cases of SSI, the researcher personally followed the patients in the preoperative period, in the POI and at the time of hospital discharge, using a data collection instrument. In order to evaluate the occurrence of SSI after hospital discharge, the researcher used the following strategies: a review of the chart associated with patient follow-up during outpatient return when possible, which would occur on average on the 35th postoperative day; telephone contact from the 30th day until the 40th postoperative day (PO), using a post-discharge surveillance instrument. Continuous and discrete quantitative variables were evaluated using the Wilcoxon-Mann-Whitney test.

Qualitative (categorical) variables were evaluated using the Pearson X² test. The Wilcoxon-Mann-Whitney test was used for qualitative (categorical) variables, whose distribution was different from normal.
