How should I refer a patient with bipolar disorder to psychiatry, including documentation of age, gender, symptom timeline, psychiatric and medical history, current medications, labs, safety assessment, and urgent referral criteria?

How to Refer a Patient with Bipolar Disorder to Psychiatry

Immediate Referral Criteria (Urgent/Emergency)

Refer immediately to emergency psychiatric services or inpatient psychiatry if the patient exhibits active suicidal ideation with plan or intent, acute psychotic symptoms with dangerous behavior, severe mania with impaired judgment posing safety risk, or inability to care for basic needs. 1, 2

• Bipolar disorder carries an annual suicide rate of approximately 0.9% (compared to 0.014% in the general population), with 15-20% of individuals dying by suicide 3
• Acute manic episodes with psychotic features require immediate psychiatric evaluation and often hospitalization 1, 2

Essential Documentation for Psychiatry Referral

Demographic and Identifying Information

• Document patient's age, gender, and contact information 4
• Note current living situation and available support systems 4

Symptom Timeline and Episode Characterization

Provide a detailed longitudinal timeline (life chart) documenting the onset, duration, and pattern of mood episodes, including periods of mania/hypomania, depression, and euthymia. 1, 2

• Specify whether manic episodes lasted ≥7 days (or required hospitalization) for Bipolar I, or hypomanic episodes lasted ≥4 days for Bipolar II 2, 5, 3
• Document decreased need for sleep (feeling rested after only 2-4 hours), distinct periods of elevated/expansive mood, increased goal-directed activity, racing thoughts, and grandiosity 1, 2
• Note whether irritability is episodic (suggesting bipolar) versus chronic (suggesting alternative diagnoses) 2, 5
• Describe depressive episodes: duration, severity, presence of psychomotor retardation, hypersomnia, or psychotic features 1, 6
• Document rapid cycling if ≥4 distinct mood episodes occurred within 12 months 1, 2

Psychiatric History

• List all prior psychiatric diagnoses, including any that may have been incorrect 2
• Document history of psychiatric hospitalizations and emergency department visits for mood-related issues 2
• Critically important: Note any antidepressant-induced mood elevation, agitation, or manic switching, as this strongly suggests underlying bipolar disorder 1, 2, 3
• Include response to past psychiatric medications (lithium, valproate, antipsychotics, antidepressants) 1, 2

Family Psychiatric History

• Document family history of bipolar disorder, as first-degree relatives have a 4-6 fold increased risk 2
• Note family history of other mood disorders, suicide, or psychiatric hospitalizations 1, 2

Current Medications and Allergies

• List all current psychiatric and non-psychiatric medications with doses 2
• Document medication allergies and adverse reactions 2
• Note adherence patterns, as >50% of bipolar patients are non-adherent 3

Laboratory and Medical Workup

Include recent laboratory results to exclude organic causes and establish baseline for psychiatric medication monitoring: 1, 2

• Thyroid function tests (TSH, free T4) 1, 2
• Complete blood count 1, 2
• Comprehensive metabolic panel (including renal function: BUN, creatinine) 1, 2
• Fasting glucose and lipid panel 1
• Pregnancy test for females of childbearing age 1
• Toxicology screening if substance use is suspected 2

Medical History and Comorbidities

• Document chronic medical conditions, particularly cardiovascular disease, metabolic syndrome, obesity, diabetes, and thyroid disorders 2, 3
• Note that bipolar patients have higher rates of metabolic syndrome (37%), obesity (21%), type 2 diabetes (14%), and cardiovascular disease 3

Safety Assessment

Conduct and document a thorough suicide risk assessment, as this is the highest mortality risk in bipolar disorder: 1, 2, 3

• Prior suicidal ideation, plans, attempts (including aborted or interrupted attempts) 2
• Current suicidal thoughts, intent, access to lethal means 1, 2
• History of aggressive behaviors, homicidal ideation, or violence 2
• Current impulsivity level 2

Substance Use History

• Document current and past use of alcohol, marijuana, cocaine, hallucinogens, tobacco, and other substances 2
• Note temporal relationship between substance use and mood symptoms to rule out substance-induced mood disorder 2, 5
• Rates of substance abuse are particularly high in adolescents with bipolar disorder 2

Comorbid Psychiatric Conditions

Screen for and document common comorbidities that require integrated treatment: 2, 3, 7

• Anxiety disorders 2, 3
• ADHD (particularly in pediatric populations) 2
• Substance use disorders 2, 3, 7
• Eating disorders 3, 6
• PTSD 2
• Personality disorders 2

Functional Impairment

• Describe impact on work/school performance, relationships, and activities of daily living 2
• Note any recent changes in functioning during mood episodes 2

Referral Format and Communication

Written Referral Components

• Summarize chief complaint and reason for referral in opening paragraph 4
• Provide concise but complete information in bulleted format for easy review 4
• Include your contact information for questions or clarification 4
• Specify urgency level: routine (weeks), urgent (days), or emergent (same day) 1

Collateral Information

Whenever possible, obtain and include information from family members or other observers, as patients often lack insight during manic episodes and can describe behavioral changes more objectively. 2

Common Pitfalls to Avoid

• Never delay referral waiting for "complete" workup if safety concerns exist 1
• Do not dismiss bipolar disorder in patients presenting with depression alone, as depressive episodes are the most common presentation and patients spend 75% of symptomatic time depressed 3, 6
• Avoid labeling treatment-resistant depression without considering bipolar disorder, as bipolar depression may respond poorly to antidepressants and these medications can destabilize the illness 5, 6
• Do not overlook substance-induced mood symptoms; always document temporal relationships 2, 5
• Never assume a single assessment is sufficient; bipolar disorder diagnosis often requires longitudinal observation 2

Special Populations

Pediatric and Adolescent Referrals

• Peak age of onset is 15-25 years, making adolescent referrals common 3
• Document that DSM criteria (including duration) must be followed in children and adolescents 2
• Note that juvenile mania often presents with irritability, lability, and mixed features rather than euphoria 2
• Differentiate from ADHD, disruptive behavior disorders, and PTSD 2
• Exercise extreme caution diagnosing bipolar disorder in children under age 6, as diagnostic validity is not established 2

Geriatric Referrals

• Document cognitive status, as dementia may coexist 4
• Note increased vulnerability to medication side effects 1

Expected Timeline

• Routine referrals: psychiatry appointment within 2-4 weeks 4
• Urgent referrals: within 1-7 days for active symptoms without immediate safety risk 4, 1
• Emergent referrals: same-day evaluation for safety concerns 1
• Mean delay from initial depressive episode to diagnosis is approximately 9 years; early referral improves prognosis 3
