Welcome Day-2 (Recruitment and Retention)

[Guest guest]

Dear Members and friends

Welcome you all for the discussion of "Recruitment and Retention of Participants in Clinical Trials".

In continuation to funnel effect...................................

This funnel effect could be extended to include dropout and discontinuation during the clinical trial, but these events are separate and relate to the clinical trial and not to the process of patient recruitment. Typically, subjects either dropout on their own or are discontinued by the investigator. If some or all dropouts are to be replaced in a trial then additional subjects must be recruited.

Dropout rates vary widely (1- 50%) and are influenced by the following factors:

· outcome measure being used

· length of follow up

· type of study intervention

· the trial population itself.

Warm Regards
