Clinical Scorecard: Mortality Rates from All Causes and Specific Conditions in Individuals Diagnosed with Bipolar II Disorder

At a Glance

Key Highlights

• BD-II is characterized by at least one major depressive episode and one hypomanic episode without a history of mania.
• Lifetime prevalence of BD-II is approximately 0.4%, with higher rates in females.
• BD-II is associated with a significant increase in all-cause mortality, particularly from suicide and cardiovascular disease.
• Patients with BD-II may experience a 10- to 20-year reduction in life expectancy.
• Mortality studies often do not differentiate between BD-II and BD-I, leading to uncertainty in specific mortality profiles.

Guideline-Based Recommendations

Diagnosis

• Diagnosis requires at least one major depressive episode and one hypomanic episode.
• Use ICD-9-CM and ICD-10-CM codes for accurate diagnosis.

Management

• Monitor depressive and hypomanic episodes closely.
• Consider the impact of prescribed agents on mortality risk.

Monitoring & Follow-up

• Regular follow-up for psychiatric health care use and medical comorbidities.
• Assess risk factors for suicide and cardiovascular disease.

Risks

• Elevated risk of suicide (12-fold) and other unnatural causes (7-fold).
• Increased natural-cause deaths, particularly from cardiovascular disease.

Patient & Prescribing Data

Individuals diagnosed with BD-II aged 12 years and older.

Treatment should address both depressive and hypomanic symptoms while considering the potential adverse effects of medications.

Clinical Best Practices

• Utilize a comprehensive approach to manage both psychiatric and physical health comorbidities.
• Engage in family-based interventions to minimize environmental confounding factors.
