Psychotropic drug initiation in patients diagnosed with chronic myeloid leukemia: a population-based study in France

Psychotropic drugs (PD) are often used close to a cancer diagnosis and may be considered as a way of coping. We aimed to determine the incidence of anxiolytics, hypnotics, antidepressants, and antipsychotics initiation around a diagnosis of chronic myelogenous leukemia (CML). Population-based cohort: Data were extracted from Systeme National des donnees de Sante (SNDS, the French health insurance database) at the regional level (Midi-Pyrenees area, 2.9 million inhabitants). All newly diagnosed patients treated by a CML tyrosine kinase inhibitor (TKI) between 10/01/2011 and 04/01/2014 were included. Pre-CML (9 months before to 3 months before first TKI prescription-F-TKI) and CML (3 months before to 9 months after F-TKI) phases were defined. The main evaluation criterion was the initiation of PD during CML phase. Determinants associated with this incident PD use were studied through a logistic regression model. We compared pre-CML and CML healthcare consumption. The cohort included 103 patients (mean age of 60.8 years). PD initiation rate was 35.9%, anxiolytics being the most initiated PD (59.5%). Advanced age was associated with PD initiation (adjusted OR = 1.029, 95% CI = 1.001-1.056). The number of consultations during the pre-CML phase and female gender tended to be associated with increased risk of PD initiation in univariate analysis. For PD initiators, healthcare consumption was greater in CML but not in pre-CML phase. PD initiation is a frequent finding around a CML diagnosis. Its risk increases with age. It could be a way to identify a subgroup with higher healthcare consumption.
