In 2011 health policy dictated a reduction in iatrogenic infections, such as Clostridium difficile (C. diff), this resulted in local change to antimicrobial policy in orthopaedic surgery. Previous antimicrobial policy was Cefuroxime, this was changed to Flucloxacillin and Gentimicin. Following this change an increased number of patients appeared to suffer from acute kidney injury (AKI). We initially evaluated the incidence of AKI pre and post antibiotic change and found a correlation between the Flucloxacillin and AKI. We then made changes to antibiotic policy to mitigate the increased rates of AKI and proceeded to evaluate the outcomes.

In this prospective study all patients admitted with fracture neck of femurs were identified from the National Hip Fracture database and data obtained. The degree of AKI was classified according to the validated RIFILE criteria.

Evaluation showed a 4 fold decrease, from 13% to only 3%, in AKI after introduction of the modified antibiotic policy. C.difficile continues to be non-existent since this change.

Flucloxacillin obviously had a significant impact on this patient group. However, we have shown that with appropriate changes to antibiotic policy AKI associated morbidity can be significantly reduced. Dose dependent antibiotics will now be given based on weight and eGFR.

In late 2011 there was a change in antimicrobial policy in orthopaedic surgery to reduce the Clostridium difficile (C. diff) rate, this was inducted top down from government, to PCT, to hospital trust. The previous antimicrobial policy was Cefuroxime, this was changed to Flucloxacillin and Gentimicin. Following this change it was noticed an increased number of patients appeared to suffer from acute kidney injury (AKI). This led us to evaluate the incidence of AKI pre and post antibiotic change and look at the causes behind this.

In this retrospective study all patients admitted with fracture neck of femurs were identified from the National Hip Fracture database and data pulled. The degree of AKI was classified according to the validated RIFILE criteria.

Evaluation showed 2–4 fold increase in AKI since antibiotic change. Although mortality was decreased in these patients, the incidence of AKI had increased significantly. However, C. difficile has been obliterated by this change.

The investigation highlights potential problems with increased rates of AKI amongst NOF patients, since antibiotic change. Flucloxacillin may have significant impact on this patient group. Dose dependent antibiotics will now be given based on weight and eGFR. Further analysis of this new change needs to be evaluated.

The Enhanced Recovery Pathway aims to improve the patient experience as well as expediting discharge. We aim to discharge 85% of patients by day 3. This audit retrospectively looked at primary total hip replacements (THR) and total knee replacements (TKR) patients who had 7 days length of stay and evaluated the factors contributing to the delay.

There were 24 patients who stayed 7 days, 12 THR and 12 TKR. There were 15 females and 7 males, the mean age was 77 years (52 to 89). Causes for the delay included patient's reluctance to engage in their rehabilitation (21/24) and Occupational Therapists (OT) identifying difficulties in patient's home circumstances on admission (12/24). Medical problems also delayed early mobilisation, particularly urethral catheterisation (9/24), investigation for venous thromboembolism (6/24) and blood transfusion (3/24).

Delay in discharge is multifactorial and requires involvement of MDT. We have identified ways to enhance patient engagement, including a “patient journey” DVD shown preoperatively at “Joint School” and individual white boards for daily goal setting. Fostering greater self-efficacy in patients may improve participation in preoperative discharge planning with OTs. Specific preoperative education may help patients understand the importance of continuing their rehabilitation while medical problems are managed.

Introduction: Periprosthetic fractures are an infrequent but increasingly prevalent problem and can be technically difficult to manage. Various techniques have been described to manage periprosthetic supracondylar fractures around a Total Knee Replacement (TKR) including, immobilisation, plate fixation, rush rods, LISS (less invasive stabilisation system) and retrograde nailing. The aim of this retrospective study was to evaluate the effectiveness of the retrograde intramedullary nail.

Methods: We identified all patients who underwent retrograde intramedullary nail for the treatment of periprosthetic femoral fractures between January 1999 and October 2005. Notes, x-rays and operation data were examined retrospectively. Outcomes were measured by radiological union, limb alignment, return to function, pain and complications.

Results: Of the 15 patients 2 died of coexisting medical problems during the follow-up period, but both with good fracture alignment. 13 united between 12 – 24 weeks (mean 15 weeks), 11 regained pre-injury function with alignment good in 12. 12 were pain free at follow-up, 2 patients required non-steroidal analgesia intermittently. There was one delayed union (53 weeks). There was one post operative complication where a patient with bilateral fractures required one night stay on ITU.

Conclusion: Intramedullary nailing of periprosthetic fractures around a TKR gave excellent functional results and 100% union in this series.
