BNMS SeHCAT Survey

Welcome to the BNMS SeHCAT Survey

It would be greatly appreciated if you could take a few minutes to complete this survey relating to SeHCAT testing. It is hoped that the information provided will be of interest to other practitioners using the technique.

Please respond even if you don't use SeHCAT currently, this will involve only answering two questions apart from your own details.

If you don't know the answer to any of the questions, or it would be too time-consuming to find out, we'd rather you left those questions blank rather than not returning the survey at all.

Once you start the survey, it is possible to leave it partly completed and come back to it later (if you leave the page/close the browser before finally submitting it). Your replies will be preserved provided you access the survey again from the same computer (your previous replies are linked by a cookie stored on the computer on which you access the survey).

Any questions, please contact

Dr Mike Smith, Rotherham General Hospital email: [email protected]
