The administration of prophylactic antibiotics is essential in the prevention of surgical site infection, particularly when metalwork is implanted. Intravenous Cefuroxime has been the antibiotic of choice for prophylaxis in our unit over the last few years. Unfortunately this has been linked to an increased rate of Clostridium Difficile infection. Our departmental antibiotic prophylaxis guidelines, based on the Scottish Intercollegiate Guidelines Network (SIGN), were therefore revised, such that intravenous Flucloxacillin and Gentamicin became the first line agents.

We primarily aimed to assess whether prophylactic antibiotics were being administered according to our revised local guidelines. Steps were then taken to improve adherence to the guidelines, and the audit repeated.

Data was collected prospectively between 1^st November 2010 and 28^th November 2010 (cycle 1). Demographic data, type of surgery, details of choice, dose and timing of antibiotic administration were compiled. The quality of documentation was also reviewed. Interventions to improve adherence to the guidelines were commenced between 1^st January 2011 and 28^th February 2011. This included a departmental presentation, supplementary distribution of the guidelines and email communication to all orthopaedic surgeons and anaesthetists to increase awareness. A repeat audit cycle was performed between 1^st March 2011 and 28^th March 2011 (cycle 2). All data was stored and statistically analysed using SPSS for Windows 17.0.

A total of 130 patients were included, with 65 patients in each cycle. Demographic data and type of surgery were reasonably similar in both cycles. Intravenous antibiotics, when required, were administered within 30 minutes of the surgical incision in most cases in both cycles of the audit. In the first cycle of the audit only 9 out of 65 patients (14%) received the correct antibiotics as suggested by our updated guidelines. This improved significantly to 46 out of 57 patients (81%) in the second cycle. Documentation of antibiotic prescribing in the anaesthetic record, operation note and drug charts also improved in the second cycle.

We observed poor initial adherence to our updated guidelines as most patients received incorrect antibiotic prophylaxis. However, following our audit interventions to increase awareness of the new guidelines, we witnessed a significant improvement in compliance. Our next step will be to ensure that the new policy of using intravenous Flucloxacillin and Gentamicin does indeed reduce the rate of Clostridium Difficile infection while maintaining a low rate of deep and superficial wound infection.

Adverse weather conditions during the winter months put increased pressure on orthopaedic trauma departments across the country. The increased incidence of injuries has resulted in a strain on resources at a local level and a situation can arise whereby cases need to be prioritised according to clinical need and fitness of the patient. Ankle fractures, frequently caused by slipping in adverse weather conditions, tend to be an injury where a high proportion of patients are young and active and can therefore cope better physiologically waiting several days for their operation. It is well documented that there is a window of opportunity when operating on ankle fractures, during which the swelling will permit fixation. We aimed to establish whether a link exists between delay to surgery for ankle fractures, the length of post-op hospital stay and the rate of complications.

We included all patients who underwent surgical fixation of an ankle fracture over a three month period between 1.1.10 and 31.01.11. Data was obtained through theatre records, discharge and clinic letters and from the local PACS X-ray system. Basic patient data, admission, theatre and discharge dates were collected along with details regarding mechanism of injury, type of fracture, fixation and documented complications. Patients were subdivided into two groups: those who underwent surgery within 48 hours of injury and those who waited longer than 48 hours. Many of the patients in the delayed surgery group remained inpatient until after their surgery whilst those more capable of mobilising with crutches were allowed home to elevate.

64 patients underwent fixation of an acute ankle fracture during the three month study period. 28 patients (44%) had a documented fall on ice or snow. 29 patients were operated upon within 48 hours. 35 patients surgery was delayed by a mean of 9 days (3-28). The mean length of post op hospital stay for the early surgery group was 3.00 days. In the delayed surgery group the mean length of stay was 4.28 days (p=0147). There were 4 complications in the early group (14%) compared with 7 in the delayed group (20%).

Delaying surgery for ankle fractures more than 48 hours suggests a trend towards an increased length of post-operative hospital stay and a slightly increased rate of complications but not to significant levels. A larger sample size may have provided a significant difference. Given this trend, we recommend early fixation of ankle fractures wherever possible providing soft tissue swelling allows tension free wound closure.
