Complications were 1 fractured greater trochanter wired intra-operatively and 1 femoral nerve palsy which resolved in 3 months. There were no PE’s, dislocations or deep infections. No hip replacement has required revision.
This is a prospective study to determine if we could identify patients who may benefit from preoperative catheterisation in lower limb arthroplasty. 211 consecutive patients undergoing total hip and knee arthroplasty were recruited. There were 131 female (62%) and 80 male (32%), the mean age (+−1 S.D.) was 68+−12 years old. Patients’ demographic details and pre-operative urinary symptoms were recorded. Previous urological surgery and past history of urinary catherisation were also documented. The anaesthetist who was blinded from the study selected the type of anaesthesia and the post-operative analgesia regime. All patients were required to produce mid-stream urine sample before surgery and at post-operation. Urine tract infection was confirmed on a positive microbiological culture. Regression analysis was used to assess various co-variables to identify the high-risk groups. 35 female (56%) and 27 male (44%) were catheterised, the mean age (+−1 S.D.) was 72+/−14 years old. The frequency of catheterisation was unrelated to the surgical procedure, the type of anaesthesia or the postoperative pain control regime. Age over 65 years old and nocturia were significant indicators for urinary catheterisation (p<
0.05). Patients with urinary incontinence and nocturia were strong determinant for urinary catheterisation (p<
0.03). Males over the age 65 years with a past history of urinary catheterisation (p=0.037) were more likely to be catheterised than females of the same group (p=0.947). This has become more evidential if patients have coexisting urinary incontinence and nocturia (p=0.005). Females over the age of 65 years with urinary incontinence were also significant (p=0.013). The sensitivity for urinary catheterisation in patients over the age of 65 years with previous history of catheterisation, urinary incontinence or nocturia was 89.7%. This group of patients would benefit from pre-operative urinary catheterisation.
To assess the cost involved and whether orthopaedic patients with Methicillin-resistant Staphylcoccus aureus (MRSA) infections were being managed according to national guidelines, retrospective survey of all MRSA infections over a 26 months period was performed. Demographic details and risk factors were identified. Infection control measures were compared with national guidelines. Total length of hospital stays, treatments received and cost were noted. In total, 78 patients were diagnosed with a MRSA infection (31 male and 47 female) with a mean age 66.4 years +/− 20.8 SD. MRSA infections occurred in 75 (97%) trauma patients and in 2 (3%) elective patients. MRSA infections were isolated from wounds in 62 patients, others sites include sputum, blood, urine and skin colonization. The average time of diagnosis after admission was 20.6 days +/− 16.6 SD. Major risk factors were internal fixation of fractures (97%), previous antibiotics (97%), nursing home residents and hospital transfers (50%). Normal national guidelines were followed in 86% of the cases. Antibiotics were used in 67 patients after microbiological confirmation; this additional cost exceeded £19,000. The mean hospital stay was 50.7 days and the cost of hospitalization per patients exceeded £19,700 (£388.60 per day). Incidence of MRSA infection in trauma and elective patients were 2.4% and 0.1% respectively. Infection control policies were strictly followed in 86% of the cases. Long hospitalization and antibiotics were a significant risk factor for developing MRSA infections. Considering the low incidence of MRSA infection in elective surgery, segregation of trauma and elective patients is an important measure in reducing the incidence and cost of MRSA infections. Substantial saving can be achieved with firmer antibiotics policies.
Do patients’ recollections of disease severity following joint replacement surgery accurately reflect their pre-operative disability? Oxford Knee score questionnaires were sent to 100 patients who had undergone primary knee replacement surgery between January 1998 and July 2000.They were asked to complete these in a manner reflecting their pre-operative disability. The results were then compared with actual scores completed by the same group of patients prior to their surgery. The response rate was 78%.The mean pre-operative score was 45 compared to the recall score of 46.9. The difference was not significant (p=0.77).We believe that recall of disability using a simple knee score is a reliable method of assessing pre-operative disability.
There is a legal and ethical obligation to gain informed consent before treatment commences. A number of bodies have issued guidelines for obtaining consent and these include the Department of Health, the GMC, The Royal College Surgeons of England, and the B.O.A. For a patient to give their informed consent to surgery they must receive sufficient information about their illness, proposed treatment and its prognosis. There are no specific guidelines regarding joint replacement. With this in mind a retrospective case note study was undertaken involving 100 patients who had undergone a hip replacement. Noting the documented discussion at all stages of patient contact.Fifty percent of patients had been seen and listed in the Outpatients by a Consultant, 25% were discussed with the Consultant responsible and the remainder were listed without Consultant input. In only 33 % of cases were any specific risks recorded. This had fallen to 4% on their visit to pre operative assessment clinic. All the consent forms were completed at the time of admission for surgery. Forty percent of these on the day of surgery. The majority were completed by SHOs (58%), while only 4% were completed by consultants. None of the forms noted the lead surgeon. All the consent forms noted some frequently occurring risks. However there was a large variance in the details recorded. The study highlights that the majority of complications are only documented on the consent form, with little note of the dialogue leading up to it. It is also apparent that there is no agreement as to what represents a significant or frequent complication. This review raises a number of important issues. There needs to be a national standardisation of the process of consent. We propose the introduction of a specific consent form for hip replacements that provide improved documentation of the standardised risks involved. This should also include guidelines regarding prosthesis choice, surgical approach and the extent of trainee involvement. In addition we would also suggest there is a need to improve sequential documented discussion up to the point of surgery and introduce specific training for juniors carrying out consent.
Cross match practice for patients with femoral neck fractures continue to cause concern due to a failure of compliance to the existing protocols. We addressed this issue by conducting a number of studies over three years and we report the summation of the studies and demonstrate the reasons for the poor compliance. We provide a simple and effective protocol that has helped reduce preoperative cross matching of femoral neck fractures from 71% to 16.7% two years after its introduction.
Retrospective review of the cross-match practice for 240 femoral neck fractures and reviewed the changes in pre-operative and post-operative haemoglobin levels and association with surgical procedure.
Postal questionnaire of 129 anaesthetic and orthopaedic trainees assessing the perceived cross-match requirements of patients with femoral neck fractures based on preoperative haemoglobin values between 8–13g/dl. In addition reviewed the source of trainees perceptions and practice Study 3 Review of the efficiency of the cross-match protocol two years after its introduction Results
71% patients with femoral neck fractures were cross-matched at admission but only 29% of the patients were subsequently transfused. From the 384 units of blood ordered at admission 230 were returned unused. Inter-trochanteric fractures had a mean blood loss of 3.1g/dl (range 1.5–7.2g/dl) following surgery in comparison to a mean loss of 1.7g/dl (0.9–3.4g/dl) for patients with displaced subcapital fractures
Orthopaedic trainees at all levels of training requested more blood then their anaesthetic counterparts for patients with femoral neck fractures. There was misconceptions regarding blood loss following surgery amongst all trainees and only 14.3% trainees used existing literature to guide their cross-match practice where as 53.4% devised protocols based on their own or colleagues’ experience.
Cross-match protocol was working effectively. Only 16.7% of the patients with femoral neck fractures were cross-matched on admission. Conclusion Cross-match recommendations fail to influence trainees. In order to address this we produced a protocol that does not rely on orthopaedic trainees. The haematology MLSO provides the appropriate amount of preoperative blood for the patient based on our finding of blood loss of different fracture patterns and the patients’ preoperative haemoglobin level. Our results show our protocol is still effective two years following its introduction despite numerous changes in trainees during this period.
This study was performed to evaluate the pre-operative concerns of patients undergoing total knee or hip replacement surgery. A cross-sectional study of 370 patients was performed. The patients completed a postal questionnaire on 29 concerns, each rated on a scale of 1 (not concerned) to 4 (very concerned). SF-12 and Oxford knee or hip scores were also calculated. Analysis was carried out using chi-squared test. 217 questionnaires were returned. The results showed that the greatest concern for patients was cancellation of their operation. This was followed by failure of the operation to reduce pain, loss of a limb and joint infection. Concerns regarding scar problems, nursing care and preoperative tests were the lowest. Women showed statistically significant greater concerns in 9 areas. Younger patients (age<
65) showed increased concerns in 8 areas. Patients who had previously undergone joint replacement were less concerned than those who had not had previous lower limb joint replacements for 6 responses. They showed increased concern in 2 areas, nursing care and hospital food. Those undergoing total hip replacement were more concerned about dislocation, dressing and returning to work (all p<
0.05). The mean Oxford Knee or Hip Score was 42.96 and 45.12 respectively (scale 12–60, 60 being most severe symptoms). The mean SF-12 scores were 41.14 for the mental component and 28.70 for the physical component score (scale 0–100, 100 representing greatest level of good health). The mean level of concern is low at 1.9 (scale 1 to 4). It is encouraging that patients who have had a previous joint replacement are generally less concerned. Possible reasons for increased concerns amongst women and younger patients are discussed. SF-12 and Oxford Knee/Hip Scores are comparable with other studies. In conclusion, this study provides useful information for the preoperative counselling of patients and the production of pre-operative literature.
