Abstract

Background: Cytochrome P-450 2D6 (CYP2D6) and 2C19 (CYP2C19) are known to contain functional polymorphisms that can alter the metabolic rate of many antidepressants (AD) and antipsychotics (AP). Individuals with no metabolic activity and with increased activity may be at risk for an unsatisfactory drug response. Objectives: Aim of this study was to assess the influence of CYP2D6 and CYP2C19 phenotypes on the consumption of care in psychiatric patients. Methods: The study was conducted in a psychiatric hospital in the Netherlands, including all admissions from July 2001 until July 2010, of patients genotyped for (at least) the CYP2D6 ∗3 ∗4 and gene multiplication and CYP2C19 ∗2. Patients were classified as poor metabolizers (PM), ultrarapid metabolizers (UM), intermediate metabolizers (IM) and extensive metabolizers (EM). To study the consumption of care, several outcome measures were calculated for PM and UM and compared to EM. Results: 7377 admissions were analyzed, belonging to 3859 unique patients. The total duration of hospital stays with AP and/or AD treatment was longer for CYP2D6 UM than for CYP2D6 EM (66 versus 48 days, p
