Core Outcomes for Early Phase Surgical Innovation and Devices: the COHESIVE study
Are you a surgeon innovator, researcher, trialist or device manufacturer?
The COHESIVE study developed a core outcome set (COS) for evaluating new surgical procedures and devices. Use of the COS in all early phase studies will make innovation safer, more transparent and ensure efficient evaluation. The final COS consists of 8 outcome domains, including outcomes specific to innovation and outcomes shared with effectiveness studies (randomised controlled trials).

How was the COS developed?
The COS was developed with multiple international stakeholders, and using robust methodology. You can read more about this in the published protocol. Explanations of each outcome domain are available for download here (PDF, 257kB) or can be viewed in the results publication.
The COS is freely available and ready for use in research, clinical practice and audit.
Next steps
A core measurement set is currently being developed to define optimal measurement instruments to assess the outcomes domains in the COHESIVE COS.
Our Ennovate study is also developing an electronic platform for the real-time measurement and sharing of information and outcomes of surgical innovation.
