Antidepressant prescribing: a comparison between general practitioners and psychiatrists
1Department of Psychological Medicihe, Ely Hospital, Cardiff.
Summary
Psychiatrists prescribed higher antidepressant dosages and longer treatment durations than general practitioners. Both groups frequently deviated from recommended dosages and treatment lengths, indicating a need for improved prescribing education.
Area of Science:
- Psychiatry
- General Practice
- Pharmacology
Background:
- The 'defeat depression' campaign highlights the need for appropriate antidepressant prescribing.
- General practice plays a key role in managing depression.
Purpose of the Study:
- To examine and compare the antidepressant prescribing patterns of general practitioners and psychiatrists.
- To identify potential discrepancies in treatment approaches.
Main Methods:
- A postal questionnaire survey was distributed to 123 general practitioners and 97 psychiatrists in South Wales.
- Response rates were 60% for general practitioners and 67% for psychiatrists.
Main Results:
- Psychiatrists used significantly higher daily antidepressant dosages and longer treatment durations for adult and elderly patients compared to general practitioners.
- A substantial proportion of general practitioners (52%) and psychiatrists (17%) reported using sub-therapeutic daily dosages for adults.
- Many general practitioners (40%) and a smaller percentage of psychiatrists (7%) employed shorter-than-recommended continuation therapy periods (less than four months).
- Both specialties exhibited considerable variability in the utilization of maintenance therapy.
Conclusions:
- Significant differences exist in antidepressant prescribing habits between general practitioners and psychiatrists.
- Both groups demonstrate suboptimal prescribing practices regarding dosage and duration.
- Targeted educational interventions are recommended to enhance the prescribing competence of both general practitioners and psychiatrists.
