Do practitioners managing mood disorders work to a sub-typing or a 'one size fits all' model?

Area of Science:

• Psychiatry
• Pharmacology
• Mood Disorders

Background:

• Mood disorders encompass various subtypes, including bipolar I, bipolar II, and unipolar depression.
• Psychotropic medication selection is a critical aspect of mood disorder management.

Purpose of the Study:

• To investigate whether community-based psychiatrists utilize a mood disorder sub-typing model in their psychotropic medication prescribing practices.

Main Methods:

• Data collected from patients at the Black Dog Institute depression clinic.
• Analysis of previously prescribed and current medications, their effectiveness, and reasons for cessation.
• Medication prevalence was analyzed based on specific diagnoses: bipolar I, bipolar II, unipolar melancholic depression, and unipolar non-melancholic depression.

Main Results:

• Psychiatrists demonstrate differential prescribing patterns aligned with specific mood disorder diagnoses.
• This diagnostic-specific prescribing was evident for both past and current medications, particularly mood stabilizers and antipsychotics.
• Some medications were trialled across the majority of patients irrespective of their diagnosis.

Conclusions:

• Community psychiatrists appear to employ a sub-typing model for mood disorders.
• Medication choices are preferentially made based on the specific subtype of mood disorder diagnosed.
