How do you navigate situations where patients request treatments that are not evidence-based?

Today it is not uncommon for patients to want "alternative modalities" or "Complimentary medical treatments". Inquire about any policies governing a patient's right to receive this within your institution. The University Medical Center where I took students for clinicals had a massage therapist, hot stone therapist, NP who did Theraputic Touch and a Reiki Master who would give treatments. They permitted ceremonies done by various clergy of many different faiths from Roman Catholic to Voodoo, but no burning incense nor lit candles were permitted. Herbal preparations had to be approved by both the MD (who often knew nothing about their properties and use) in conjunction with the pharmacy department (who almost always did) to prevent interactions with standard medications given. Then the non-formulary preparations had to be written as a specific kind of prescription in order for a nurse to give them. If you don't have a committee to look at this issue, try to start one. Complimentary treatment is NOT going away, and having policy on this can save a lot of grief in the future.
