The findings of this paper reflect the pooled experience of members from only ten with the CTUs registered with the UK Clinical Investigation Collaboration in . Although this sample of CTUs is diverse in terms of funding, portfolios and organisation, it is unlikely that they are totally representative of all UK units. In unique, the comparative costs exercise is based on detailed feedback from a selfselected sample of just 5 CTUs that had been able to prioritise an unfunded contribution to this exercise, fewer than thought of satisfactory for thematic saturation . Our remit didn’t permit a detailed in the influence of access to core infrastructure on the charges and activity of any unique CTU, while the group felt that such access had a vital effect on analysis costsHind et al. A second limitation could be the extent to which costing of your vignette by a CTU followed processes that would have been applied when costing an actual application for funding for any trial. The formatting of the charges that have been reported by CTUs and information provided in subsequent interviews demonstrated that the fees had been generated by staff familiar with CTUs’ usual costing processes and seasoned in applying them. On the other hand, the exercise couldn’t reproduce all the formal steps for an actual grant submission and it’s probable that additional checks, essential as a part of approving a grant for actual submission, may have led to some revisions.Findings within the context of earlier trial literature of findingsOur findings confirm that, for some trial activities for instance MedChemExpress EPZ031686 statistical assistance there is outstanding similarity in approaches to costing involving CTUs. Also, despite the variations in headline CTU charges, even the lowest CTU fees exceeded . m. We mention this figure because some funding opportunities invite applications for nonpilot trials and, nevertheless, specify this, or a reduce figure, as a funding ceiling; specifying a ceiling in this way tends to result in trial budgets just below the ceiling but that are not credible.Table Consistency in part definition roles as tedRole QA Trial manager Data manager Senior statistician Junior statistician RA Administrative CTU suggestions ClericalCTU clinical trials unit, QA good quality assurance, RA research assistantConsistency (kappa) . Similarity may well arise either simply because the underlying fees of an activity are, indeed, comparable across CTUs or simply mainly because CTUs have adopted a equivalent model for costing potentially, communicated from one CTU to another because `that’s what the funder will accept’. The extent to which CTUs cost planned research in the amount of the process was discussed, and was observed to differ; some did this (albeit, not with the granularity a CRO would use) and other folks relied on standard costing templates in which many elements can vary only in the R1487 (Hydrochloride) chemical information margins from project to project. 
Several members argued that taskbased costing is hard and timeconsuming to complete, and not necessarily predictive from the actual work necessary on a project. This study has begun the procedure of documenting real differences within the activities and associated costs which CTUs really feel are essential to deliver a specific trial, and how they express these requirements.

Similarity might arise either for the reason that the underlying costs of an activity are, indeed, related across CTUs or just mainly because CTUs have adopted a similar model for costing potentially, communicated from a single CTU to another due to the fact `that’s what the funder will accept’. The extent to which CTUs expense planned analysis at the amount of the task was discussed, and was observed to differ; some did this (albeit, not with the granularity a CRO would use) and others relied on standard costing templates in which numerous components can differ only at the margins from project to project.
