1. It implements the conditional model, as described in A systematic review of models to predict recruitment to multicentre clinical trials by Barnard, Dent and Cook ( ), and because the maths is similar can generate and show the unconditional model too.
2. Recruitment Modeller is a tool for clinical researchers undertaking studies which require the prospective rectuitment of participants from multiple centres.
3. What a modelling tool like does facilitate, however, is rapid sensitivity analysis through the comparison of possible recruitment profiles across a variety of study scenarios, and tracking actual recruitment as it occurs.
4. Of course the unconditional model is rarely useful, except in single centre studies, but may be interesting as a best case example of what can be acheived.
5. The models used in Recruitment Modeller are deterministic - that is they produce the same answer every time.
6. You’ll only get a good prediction from Recruitment Modeller if you give it good data.
7. It’s well known that trials tend to over predict their ability to recruit.
8. They are also - obviously - only as good at the parameters they are given.
