  • Background: Surgical site infections (SSI) are one of the most common types of hospital acquired infections. Postoperative hyperglycemia is one risk factor that has been demonstrated to increase SSIs in with cardiac procedures, but the link to colorectal surgeries has not been established.

    Methods: This case-controlled study has evaluated post-operative serum glucose levels on day 1 and day 2 after surgery in SSI patients, and compared them to an age, sex, ASA score and surgical time matched controls. An independent sample t-test was conducted to compare the average of post-operative day one (POD1) and post-operative day two (POD2) in the SSI group to the no SSI group.

    Results: There was a significant difference in the average of POD1 and POD2 for the SSI group (Mean = 145.2 mg/dL, SD = 38.29) and no SSI (Mean = 133.5mg/dL, SD = 30.14; t (160) = 2.160, p = .032). The magnitude of the differences in the means is as follows (mean difference = 11.69, 95% CI: 1.00 to 22.37).

    Conclusion: This association of high serum glucose levels and SSI’s indicates that higher post-operative serum glucose levels may be an important risk factor for a SSI. Additional studies should be conducted to confirm these findings in a larger population set. If proven true, this knowledge will be useful in clinical practice by instituting measures that will ensure better control of serum glucose control post-operatively in order to reduce the incidence of SSIs.
