Surgical site infections in day surgery settings.

BACKGROUND

Because major complications are rare in day surgery, minor morbidities such as surgical site infections, which become evident only after patient discharge, have a major impact on the perceived quality of care. We performed an audit of such infections over a oneyear period.

METHODS

All procedures were performed in a multidisciplinary day surgery setting. There were 155 inguinal hernia repairs, 44 excisions of lipomas, and 27 excisions of pilonidal cysts. All patients received antibiotic prophylaxis according to a rotation protocol.

RESULTS

One patient (0.65%) operated on for inguinal hernia developed a deep incisional infection caused by Staphylococcus schleiferi. The patient was treated using selective antibiotics, and complete recovery ensued. One patient (2.27%) who underwent excision of a lipoma revealed developed a deep incisional infection associated with fever (39 degrees C) caused by Staphylococcus aureus. He was treated by daily antibiotics and application of dressings for two weeks and recovered. One patient (3.7%) treated for pilonidal cyst developed a deep incisional surgical site infection. A group A Streptococcus was isolated, and he received an intravenous antibiotic for ten days. In the seven patients treated for pilonidal cyst with the wound left open, swab specimens were taken because of persisting local pain, and the following bacteria were found: Pseudomonas aeruginosa, Escherichia coli, Staphylococcus epidermidis, Proteus vulgaris, and Streptococcus constellatus. No antibiotic therapy was given, and local wound care led to complete recovery.

CONCLUSIONS

In our day surgery unit, the rates of surgical site infection are similar to those described in the literature. Continuing audit is essential to maintain and improve the quality and standard of the surgery provided. Prevention of surgical site infection is very much the responsibility of the persons working in the operating theater. Therefore, it is vital not only to apply strict regulations concerning everyday management but also to maintain a high degree of motivation among the personnel.
