Explaining the rise in antidepressant prescribing: a descriptive study using the general practice research database

Area of Science:

• Pharmacovigilance
• Epidemiology
• General Practice Research

Background:

• Antidepressant prescribing has increased in the UK.
• Understanding the drivers of this trend is crucial for healthcare policy.

Purpose of the Study:

• To investigate the factors contributing to the rise in antidepressant prescribing in the UK between 1993 and 2005.

Main Methods:

• Retrospective analysis of anonymised data from the General Practice Research Database.
• Inclusion of over 3 million patients across 170 UK general practices.
• Extraction of data on new depression cases and antidepressant prescriptions from 1993 to 2005.

Main Results:

• Antidepressant prescribing nearly doubled from 1993 to 2004.
• The proportion of patients receiving antidepressants upon initial diagnosis remained stable.
• Increased long-term prescribing and treatment for recurrent depression episodes were key drivers.

Conclusions:

• The rise in antidepressant use is primarily linked to changes in long-term treatment patterns.
• Future guidelines should emphasize appropriate long-term antidepressant management and regular patient review.
• Focus needs to shift from initiation to sustained, appropriate use of antidepressants.
