BackgroundThere is limited information on the costs and benefits of alternative adjunct non-pharmacological treatments for knee osteoarthritis and little guidance on which should be prioritised for commissioning within the NHS. This study estimates the costs and benefits of acupuncture, braces, heat treatment, insoles, interferential therapy, laser/light therapy, manual therapy, neuromuscular electrical stimulation, pulsed electrical stimulation, pulsed electromagnetic fields, static magnets and transcutaneous electrical nerve Stimulation (TENS), based on all relevant data, to facilitate a more complete assessment of value.MethodsData from 88 randomised controlled trials including 7,507 patients were obtained from a systematic review. The studies reported a wide range of outcomes. These were converted into EQ-5D index values using prediction models, and synthesised using network meta-analysis. Analyses were conducted including firstly all trials and secondly only trials with low risk of selection bias. Resource use was estimated from trials, expert opinion and the literature. A decision analytic model synthesised all evidence to assess interventions over a typical treatment period (constant benefit over eight weeks or linear increase in effect over weeks zero to eight and dissipation over weeks eight to 16).ResultsWhen all trials are considered, TENS is cost-effective at thresholds of £20–30,000 per QALY with an incremental cost-effectiveness ratio of £2,690 per QALY vs. usual care. When trials with a low risk of selection bias are considered, acupuncture is cost-effective with an incremental cost-effectiveness ratio of £13,502 per QALY vs. TENS. The results of the analysis were sensitive to varying the intensity, with which interventions were delivered, and the magnitude and duration of intervention effects on EQ-5D.ConclusionsUsing the £20,000 per QALY NICE threshold results in TENS being cost-effective if all trials are considered. If only higher quality trials are considered, acupuncture is cost-effective at this threshold, and thresholds down to £14,000 per QALY.

Background: Trauma is a leading contributor to the burden of disease in Canada, accounting for more than 15 000 deaths annually. Although caring for injured patients at designated trauma centres (TCs) is consistently associated with survival benefits, it is unclear how travel time to definitive care influences outcomes. Using a population-based sample of trauma patients, we studied the association between predicted travel time (PTT) to TCs and mortality for patients assigned to ground transport. Methods: Victims of penetrating trauma or motor vehicle collisions (MVCs) in Nova Scotia between 2005 and 2014 were identified from a provincial trauma registry. We conducted cost distance analyses to quantify PTT for each injury location to the nearest TC. Adjusted associations between TC access and injury-related mortality were then estimated using logistic regression. Results: Greater than 30 minutes of PTT to a TC was associated with a 66% increased risk of death for MVC victims (p = 0.045). This association was lost when scene deaths were excluded from the analysis. Sustaining a penetrating trauma greater than 30 minutes from a TC was associated with a 3.4-fold increase in risk of death. Following the exclusion of scene deaths, this association remained and approached significance (odds ratio 3.48, 95% confidence interval 0.98-14.5, p = 0.053). Conclusion: Predicted travel times greater than 30 minutes were associated with worse outcomes for victims of MVCs and penetrating injuries. Improving communication across the trauma system and reducing prehospital times may help optimize outcomes for rural trauma patients. Contexte : Les traumatismes contribuent pour une bonne part au fardeau de la maladie au Canada; on leur attribue plus de 15 000 décès annuellement. Même si les soins prodigués aux patients victimes de traumatismes dans les centres de traumatologie désignés (CTD) sont toujours associés à des gains au plan de la survie, on ignore quelle est l'influence du temps de transfert vers le CTD sur l'issue. À partir d'un échantillon de patients polytraumatisés basé dans la population, nous avons analysé le lien entre le temps de transfert prévu (TTP) vers le CTD et la mortalité des patients transportés par voie terrestre. Méthodes : On a identifié les victimes de traumatismes pénétrants ou d'accidents de la route en Nouvelle-Écosse entre 2005 et 2014 à partir d'un registre provincial de traumatologie. Nous avons analysé la distance de coût pour quantifier le TTP à partir de chaque scène vers le CTD le plus proche. Les liens ajustés entre l'accès au CTD et la mortalité liée au traumatisme ont ensuite été estimés par régression logistique. Résultats : Un délai de TTP de plus de 30 minutes pour arriver au CTD a été associé à un accroissement de 66 % du risque de décès chez les patients polytraumatisés (p = 0,045). Ce lien s'annulait si on excluait de l'analyse les décès survenus sur la scène de l'accident. Subir un traumatisme ouvert à plus de 30 minutes de distance d'un CTD a été associé à une augmentation par un facteu...
