[Observance, adherence, compliance ...different words for better therapeutic results]

IMPROVING OBSERVANCE: For antiretroviral treatments including protease inhibitors, twice daily regimens have been tried instead of the t.i.d protocols. Available data are insufficient to determine the effect on observance. VERIFYING OBSERVANCE: Indinavir assays in the hair of treated patients have shown that the indinavir level is higher in responders than in non responders. BETTER UNDERSTANDING OF PRESCRIPTION MODALITIES: This can be a very useful tool in helping the patient understand his/her treatment and its duration.
