The STarT Back approach comprises subgrouping of LBP patients according to risk of persistent LBP-related disability, and matches patients to appropriate treatments. In a clinical trial and implementation study, this stratified care approach was clinically and cost-effective compared to usual non-stratified care. However, the long-term cost- effectiveness is unknown, and could be established with decision modelling. A systematic review of model-based economic evaluations in LBP found shortcomings with existing models, including inadequate characterisation of the condition in health states and absence of long-term modelling. This study conceptualises the first decision model of this stratified care approach for LBP management, and assesses long-term cost-effectiveness. A cost-utility analysis from the NHS perspective compared stratified care with usual care, in patients consulting in primary care with non-specific LBP. A Markov state-transition model was constructed where long-term patient prognosis over ten years was dependent upon physical function achieved at twelve months. Consultation with experts helped define condition health states, inform the long-term modelling, and choice of sensitivity analyses.Background and Purpose
Methods
Smoking is negatively implicated in healing and may increase the risk of surgical complications in orthopaedic patients. Carbon monoxide (CO) breath testing provides a rapid way of measuring recent smoking activity, but so far, to our knowledge, this has not been studied in elective orthopaedic patients. We studied whether CO-testing can be performed preoperatively in elective orthopaedic patients and whether testing accurately correlates with self-reported smoking status? CO breath testing was performed on and a brief smoking history was obtained from 154 elective orthopaedic patients on the day of surgery. All patients admitted over 6 weeks for elective orthopaedic intervention were enrolled. 16.2% patients admitted to smoking. The mean CO levels were 15.2 ppm for self-reported smokers and 3.1 ppm for self-reporting non-smokers. One self-reporting non-smoker admitted to smoking after testing. 5 non-smoking patients had a CO breath of >=7, 1 had a CO level of >= 10 ppm. Using a cutoff of 7 ppm gave a sensitivity of 65.4% and a specificity of 96.1%, whilst a cutoff of 10 ppm gave a sensitivity of 57.6% and specificity of 99.2%. Whilst most patients are honest about smoking, CO testing can identify non-disclosing smokers undergoing elective orthopaedic procedures. Due to the high specificity, speed and cost-effectiveness, CO breath testing could be performed routinely to identify patients at risk from smoking-related complications in pre-assessment clinics. Smoking cessation services may reduce the risk of harm. CO testing on admission may demonstrate the efficacy of smoking cessation services.
To determine effectiveness of Collagenase Clostridium Histolyticum (CCH) in deformity correction and hand function for patients with Dupuytren's disease. Patients with MCPJ contractures with no previous surgery to the same finger were included. Treatment consisted of one Xiapex injection to a prominent pretendinous band as an outpatient procedure. Follow up was arranged at 48 hours, 3 weeks and final follow up > 6 months.Aim
Materials & Methods
Displaced distal radius fractures in children have been treated in above elbow plaster casts since the last century. Cast index has been calculated previously, which is a measure of the sagittal cast width divided by the coronal cast width measurement at the fracture site. This indicates how well the cast was moulded to the contours of the forearm. We retrospectively analysed the cast index in post manipulation radiographs to evaluate its relevance in redisplacement or reangulation of distal forearm fractures. Consecutive radiographic analysis.Introduction
