Background: Rising numbers of patients on the liver transplant waiting list has led to the utilization of organs from higher-risk donors that are more likely to be discarded and are prone to post-transplant complications. Storage and transportation of these livers at low temperatures can cause damage. OrganOx metra is a portable device intended to preserve and maintain the donated liver in normothermic conditions for up to 24 h prior to transplantation. Objective: To evaluate the cost-utility of normothermic machine perfusion with OrganOx metra in liver transplantation compared to the current practice of static cold storage (SCS). Methods: A de novo decision analytic model (a decision tree along with a Markov model), based on current treatment pathways, was developed to estimate the costs and outcomes. Results from a randomized clinical trial and national standard sources were used to inform the model. Costs were estimated from the National Health Service and Personal Social Services perspective. Deterministic and probabilistic sensitivity analyses (PSA) were conducted to explore uncertainty surrounding input parameters. Results: Over a lifetime time horizon, liver transplantation with OrganOx metra was more costly and more effective than the current practice of static cold storage. The total costs per patient were £37,370 vs £46,711, and the total effectiveness per patient was 9.09 QALYs vs 10.27 QALYs for SCS and OrganOx metra groups, respectively. The estimated ICER was £7,876 per each QALY gained. Results from the PSA showed that use of OrganOx metra has 99% probability of being cost-effective at a £20,000 willingness-to-pay threshold. OrganOx metra led to the utilization of 54 additional livers with patients experiencing lower rates of early allograft dysfunction and adverse events. Conclusions: Use of OrganOx metra for the perfusion and transportation of livers prior to transplantation is a cost-effective strategy.

Background Acute coronary syndrome patients receiving dual antiplatelet therapy who need emergent or urgent cardiac surgery are at high risk of major bleeding, which can impair postoperative outcomes. CytoSorb ® , a blood purification technology based on adsorbent polymer, has been demonstrated to remove ticagrelor from blood during on-pump cardiac surgery. Objective The aim of this study was to evaluate the cost utility of intraoperative removal of ticagrelor using CytoSorb versus usual care among patients requiring emergent or urgent cardiac surgery in the UK. Methods A de novo decision analytic model, based on current treatment pathways, was developed to estimate the short-and long-term costs and outcomes. Results from randomised clinical trials and national standard sources such as National Health Service (NHS) reference costs were used to inform the model. Costs were estimated from the NHS and Personal Social Services perspective. Deterministic and probabilistic sensitivity analyses (PSAs) explored the uncertainty surrounding the input parameters. Results In emergent cardiac surgery, intraoperative removal of ticagrelor using CytoSorb was less costly (£12,933 vs. £16,874) and more effective (0.06201vs. 0.06091 quality-adjusted life-years) than cardiac surgery without physiologic clearance of ticagrelor over a 30-day time horizon. For urgent cardiac surgery, the use of CytoSorb was less costly than any of the three comparators-delaying surgery for natural washout without adjunctive therapy, adjunctive therapy with short-acting antiplatelet agents, or adjunctive therapy with low-molecular-weight heparin. Results from the PSAs showed that CytoSorb has a high probability of being cost saving (99% in emergent cardiac surgery and 53-77% in urgent cardiac surgery, depending on the comparators). Cost savings derive from fewer transfusions of blood products and re-thoracotomies, and shorter stay in the hospital/intensive care unit. Conclusions The implementation of CytoSorb as an intraoperative intervention for patients receiving ticagrelor undergoing emergent or urgent cardiac surgery is a cost-saving strategy, yielding improvement in perioperative and postoperative outcomes and decreased health resource use.

Background: Complications after surgical procedures are common and can lead to a prolonged hospital stay, increased rates of postoperative hospital readmission, and increased mortality. Monitoring vital signs is an effective way to identify patients who are experiencing a deterioration in health. SensiumVitals is wireless system that includes a lightweight, digital patch that monitors vital signs at two minute intervals, and has shown promise in the early identification of patients at high risk of deterioration. Objective: To evaluate the cost-utility of continuous monitoring of vital signs with SensiumVitals in addition to intermittent monitoring compared to the usual care of patients admitted to surgical wards. Methods: A de novo decision analytic model, based on current treatment pathways, was developed to estimate the costs and outcomes. Results from randomised clinical trials and national standard sources were used to inform the model. Costs were estimated from the NHS and PSS perspective. Deterministic and probabilistic sensitivity analyses (PSA) were conducted to explore uncertainty surrounding input parameters. Results: Over a 30-day time horizon, intermittent monitoring in addition to continuous monitoring of vital signs with SensiumVitals was less costly than intermittent vital signs monitoring alone. The total cost per patient was £6,329 versus £5,863 for the comparator and intervention groups respectively and the total effectiveness per patient was 0.057 QALYs in each group. Results from the PSA showed that use of SensiumVitals in addition to intermittent monitoring has 73% probability of being costeffective at a £20,000 willingness-to-pay threshold and 73% probability of being cost-saving compared to the comparator. Cost savings were driven by reduced costs of hospital readmissions and length of stays in hospital. Conclusions: Use of SensiumVitals as a postoperative intervention for patients on surgical wards is a cost-saving and cost-effective strategy, yielding improvements in recovery with decreased health resource use. KEY POINTS FOR DECISION MAKERS SensiumVitals has the potential to reduce the length of postoperative hospital stay, readmission rates, and associated costs in postoperative patients. In this study, SensiumVitals has been found to be a cost-saving (dominant) and cost-effective (dominant) intervention for monitoring the vital signs of surgical patients postoperatively.

BackgroundWe undertook a survey of all bariatric centres in Scotland in order to describe current pre- and post-operative care, to estimate their costs and explore differences in financial impact.MethodsA questionnaire was distributed to each health centre. Descriptive statistics were used to present average cost per patient along with 95% confidence intervals, and the range of costs.ResultsResults show nearly a five-fold difference in costs per patient for pre-operative services (range £226 - £1071) and more than a three-fold difference for post-operative services (range £259 - £896).ConclusionsThere is a lack of evidence base and a clear requirement for the evaluation of bariatric surgical services to identify the care pathways pre- and post-surgery which lead to largest improvements in health outcomes and remain cost-effective.Electronic supplementary materialThe online version of this article (10.1186/s40608-018-0223-3) contains supplementary material, which is available to authorized users.

survival model. The model was based on the survival data from published literature, extrapolated to 10 years (results were based on the restricted mean survival time). In BIA, the number of patients was based on data on MIS-SU-AVR in other countries. The patients using MIS-SU-AVR in the new scenario recruit from cSAVR or TAVI; the proportion was based on current diagnosis-related groups statistics. The cost of the procedure was based on current cSAVR cost, adjusting for the device cost; other costs were based of the National Health Fund data. Results: In the CEA, MIS-SU-AVR offers clinical benefits vs cSAVR and TAVI (0.1 and 1.1 life years gained, respectively) and is cost saving vs TAVI (hence, dominant). The incremental cost effectiveness ratio vs cSAVR amounts to 32,544 EUR (below the official threshold). In the BIA, there would be 102, 182, 429, and 560 MIS-SU-AVR patients in consecutive years. Introducing MIS-SU-AVR would result in net savings ('000s EUR): 73, 131, 305, and 403, respectively. Conclusions: MIS-SU-AVR is cost-effective vs cSAVR and TAVI and its reimbursement would result in net savings in Poland.

Representatives for dentists are required for many governing committees, local and national, that contribute to many aspects of the profession related to politics, the workplace, education, or community-building. Developing skills as a representative can begin as an undergraduate in student representation systems as part of UK university governance structures. At one UK dental institution, there was a plan to explore the learning and skill development of current student representatives, review the training, identify any areas where there were gaps or where they should be strengthened, and consider whether a new training programme could be developed. Training gaps in the representation process and preference for peer mentoring in training were identified as students acknowledged learning 'on the job' through observation of experienced peers. Current representation training also fell short of highlighting the relevance to their future dental profession. Staff and students co-designed a bespoke programme of training to help students develop their representation skills, as well as align them to the development of professional skills which were determined to be relevant for their future dental career.
