Mixed States: Diagnosis, Assessment and Diagnostic Stability

Area of Science:

• Psychiatry
• Clinical Psychology
• Pharmacology

Background:

• Psychiatric disorders represent a significant global health burden, with diagnostic stability being crucial for effective treatment.
• Mixed states within mood disorders are often underdiagnosed, leading to poorer prognosis, increased hospitalizations, and higher suicide risk.
• The DSM-5 introduced a specifier for mixed features in mood disorders, requiring at least three overlapping manic/hypomanic and depressive symptoms.

Purpose of the Study:

• To investigate the prevalence of mixed states in psychiatric inpatients.
• To assess the utility of the G.T.-MSRS scale in identifying mixed states.
• To explore the diagnostic and treatment patterns for patients with mixed states.

Main Methods:

• Retrospective analysis of data from 691 patients admitted to a psychiatric hospital between January 1st and December 31st, 2021.
• Administration of the G.T.-MSRS scale to assess mixed state features.
• Review of discharge diagnoses and prescribed psychotropic medications, particularly mood stabilizers.

Main Results:

• A high prevalence of mixed states was identified, with 74% of men and 76% of women meeting the criteria.
• Despite meeting criteria for mixed states, only about 31-34% of patients received an Affective Disorder diagnosis upon discharge.
• A significant majority (70%) of patients, regardless of gender, were prescribed mood stabilizers, indicating clinical recognition of mood instability.

Conclusions:

• There is a high prevalence of underdiagnosed mixed states in psychiatric inpatient populations.
• The G.T.-MSRS scale is a valuable tool for early detection of mixed states during hospitalization.
• Timely identification of mixed states can guide tailored psychopharmacological treatment, potentially improving patient prognosis and quality of life.
