Antidepressant use and resource utilization in the general practitioner setting in The Netherlands

Area of Science:

• Pharmacotherapy
• General Practice
• Clinical Pharmacy

Background:

• Antidepressant therapy is a cornerstone of depression management.
• General practitioners (GPs) play a crucial role in initiating and managing antidepressant treatment.
• Understanding patterns of antidepressant use and resource utilization is essential for optimizing patient care.

Purpose of the Study:

• To evaluate antidepressant prescribing patterns and healthcare resource utilization.
• To compare the use of selective serotonin reuptuptake inhibitors (SSRIs) versus tricyclic antidepressants (TCAs).
• To assess adherence to Dutch treatment guidelines in general practice.

Main Methods:

• A retrospective longitudinal study utilizing a Dutch patient database.
• Inclusion of 869 patients initiating therapy with either an SSRI or a TCA.
• Analysis of antidepressant therapy duration within 90 days and GP resource utilization within 180 days.

Main Results:

• SSRI initiators were younger and more likely to have a depression diagnosis compared to TCA initiators.
• Patients initiating SSRIs were more likely to receive guideline-consistent doses and therapy duration (over 30 days within 90 days).
• Extended antidepressant therapy (over 30 days) correlated with increased GP visits for both SSRI and TCA users.

Conclusions:

• SSRI initiation in Dutch general practice is more aligned with recommended doses and durations than TCA initiation.
• These findings support the guideline-adherent use of SSRIs in primary care settings.
• Further research could explore long-term outcomes and cost-effectiveness.
