Introduction

Pre-operative urine screening is accepted practice during pre-operative assessment in elective orthopaedic practice. There is no evidence surrounding the benefits, effects or clinical outcomes of such a practice.

Carpal Tunnel Syndrome is the most common entrapment neuropathy encountered in clinical practice. Previous studies have suggested that the disease has a higher prevalence in the elderly(Stevens JC etal, Neurology 1988;) and that this sub group also tends to have a higher prevalence of severe CTS.(Seror P, Ann Hand Surg 1991; Bland etal, J Neurol Neurosurg Psychiatry). Surgical decompression of the median nerve is the treatment of choice with a reported success rate of between 53 and 97 %.(Katz et al, J Hand Surg 1998).

There has been some controversy regarding the effectiveness of surgery in elderly patients. The aim of our study was to evaluate the results of carpal tunnel release in patients over the age of 75 years at the time of surgery. A literature search revealed few studies carried out in elderly patients–Weber etal-(mean age 75 years), Porter etal (mean age 59.8 years) and Leit et al (mean age 79 years). The average age of our patient group (80.4 years) is the highest reported in literature so far.

We posted questionnaires to all patients who were over 75 years at the time of their surgery. There were a total of 49 patients (65 hands) operated over the last 10 years who belonged to this age group. We used the Brigham And Women’s Hospital Questionnaire devised by Levine et al. (1993). In addition, we added some questions to assess patient satisfaction with the procedure. 65% of the patients were females. The average age was 80.4 years.

The completed questionnaires were used to calculate the Pre and Post operative scores. The mean pre operative score was found to be 3.18, which improved post operatively to 1.8. (Scale of 1 to 5, with 1 being the best and 5 the worst). Importantly, although all symptoms improved, some such as pain and numbness showed a much greater improvement than grasping power. On the Visual Analogue Scale, pain scores improved from 6.4 to 2.3 post surgery. 82 % of patients had no scar tenderness, 12 % had mild to moderate tenderness, while 6 % reported severe scar tenderness. Overall 79% of patients showed improvement, 15 % felt that the surgery had made no difference, while 6% reported worsening of their symptoms after surgery.

Our study showed that 8 out of 10 elderly patients will improve after carpal tunnel release, though all symptoms are unlikely to improve. The symptom least likely to improve is weakness of the hand. The results of this study are important to counsel this sub group of elderly patients, so that they may take an informed decision on whether to proceed with the surgery.

Introduction: Infection remains the single most important complication in elective joint replacement. 1.1% of patients suffer early deep infection and 10–17% of patients superficial infection [1]. Antibiotic prophylaxis has been used extensively in elective orthopaedic practice, approximately halving the post-operative infection rate [2]. Cefuroxime is almost universally used in the UK. However there is an increased incidence of multiple drug resistant bacteria within the environment in addition cephalosporin use and resistance is widespread [3]. Many patients are treated pre-operatively for urinary tract infections with cephalosporins, and a further group of patients are already colonised with cephalosporin resistant staphylococcus. We have previously shown that 8.1% of patients fall into one or other of these categories.

Methods: We present a prospective series of 630 serial elective orthopaedic admissions from all orthopaedic disciplines. We have examined notes and reviewed lab records in order to determine outcomes. The centre for disease control [4] definition was used for suspected infections, and confirmed with wound swabs. 48 cases were confirmed infectious from a suspected 142 cases meeting this definition.

Results: We found a positive correlation between previous urine infection, MRSA status, revision surgery, and diabetes and wound infection. Nearly 35% of bacterium cultured were cephalosporin resistant, and 12% demonstrated multiple antibiotic resistance.

Discussion: It is good clinical practice to provide antibiotic prophylaxis in joint replacement, but the blind use of cephalosporins in all patients does not make sense because of increased incidence of antibiotic resistant bacteria. We present evidence based guidelines for the use of antibiotic prophylaxis in elective orthopaedic surgery and empirical antibiotic treatment in patients with wound infection before culture results are available.

All multidisciplinary audit projects from January 1998 to March 2002 involving an Orthopaedic department were assessed to measure their impact on improving clinical practice. Data were derived from reports formulated by the Trust’s Audit department, which listed findings, conclusions and proposals for each project.

Among 41 studies performed, 37 listed a formal proposal of actions. 4 projects had a completed outcome of which 2 closed the loop with re-audit. 9 other projects recommended re-audit but none had been initiated. Although Trusts actively partake in regular audit, it seems more as a service or training commitment, rather than contributing towards improving the quality of healthcare.
