Drug Utilization Trends in Patients With Posttraumatic Stress Disorder in a Postconflict Setting: Consistency With Clinical Practice Guidelines

Objective: The objective of this study was to compare observed patterns of drug utilization among patients with posttraumatic stress disorder (PTSD) in a postconflict setting with current guidelines and to present baseline period prevalence and change in period prevalence from 2 time periods, 2002 and 2012.

Method: The study provides details of the annual number of patients with PTSD with at least 1 redeemed prescription containing the diagnostic code F43.1 according to International Classification of Diseases (ICD-10) for fiscal years 2002 through 2012 in Croatia. Using longitudinal data analysis, overall change in medication use frequency was calculated for each medication and therapeutic subgroup classified by the Anatomic Therapeutic Chemical classification system according to absolute frequency.

Results: Over the 11-year study period, the number of patients receiving pharmacotherapy associated with PTSD increased 7-fold. The annual frequency of drug use was highest for anxiolytics, with use of anxiolytics increasing from 73.32% in 2002 to 75.83% in 2012; antidepressants, from 44.56% to 61.36%; hypnotics, from 18.67% to 35.68%; and antipsychotics, from 21.81% to 30.21%. Overall change in drug utilization frequency was most prominent for hypnotics (17.01%), antidepressants (16.80%), and antipsychotics (8.40%) during the period 2002-2012.

Conclusions: Drug utilization trends in our postconflict setting were predominantly inconsistent with current guidelines for treatment of PTSD due to excessive anxiolytic use, implying that psychopharmacotherapy was used mainly for tranquilizing properties to address non-diagnosis-specific symptoms. Promising rising trends in utilization of antidepressants were not followed with compensatory reductions in anxiolytic use. These data revealed areas of inconsistent use of drugs, generating suggestions for interventions to improve drug use and also hypotheses for additional research.
