Frequently asked questions

Is the first call free?

Yes. Thirty minutes to understand the problem and tell you honestly whether we can help, and how. If we are not the right team, we say so and point you to someone who is.

Do you work with small budgets?

It depends on the scope. A rapid review answers some questions well; others need a full systematic review. On the call we narrow the scope to what you actually need in order to decide, almost always less than what gets asked for at the start.

Do you sign confidentiality agreements?

Yes, before we receive any sensitive information. We also work under whatever data processing agreements your institution requires.

Do you take on projects outside Colombia?

Yes. We work in Spanish and English. Our CEO works with the WHO in Geneva as methodologist for the iCAM guideline, directs the Colombia GRADE Network and has served as a guideline methodologist for the Saudi Ministry of Health.
