PIPC® Psychiatry In Primary Care MOOD DISORDERS Robert K. Schneider, MD Departments of Psychiatry, Internal Medicine and Family Practice The Medical College of Virginia at the Virginia Commonwealth University Richmond, Virginia PIPC® Goals • Effectively recognize, diagnose and treat mental illness in primary care • Bring the psychiatry skills and knowledge base of the primary care physician on par with other medical specialty knowledge bases Outline • PIPC 1 – Introduction – PIPC Interview ® – MAPS-O – Mood Disorders – Suicide ® Outline • PIPC 2 – Anxiety Disorders • PIPC 3 – Neurotransmitters – The 3 Phases and the 5Rs – Medications – Cases and Discussion “de facto mental health system” Regier,1978 • 54% of people with mental illness who seek treatment are exclusively seen in the “general medical sector” • 25% of patients in primary care setting have a diagnosable mental illness Why Now? • Great scientific evidence – Genetic basis for disease • Twin studies and Human Genome Project – Neuroscience Research • CT to MRI to PET to SPECT scanning • Neurotransmitter basic science • Somatic Therapies – Psychiatric Medication Explosion (“SSRI Surge”) • Economic pressures (Managed Care) PIPC Interview ® PIPC Interview • Organized by “organ system” approach – Hypothesis driven interview • Makes psychiatric knowledge assessable • Demonstrates holes in knowledge base for PCP • Creates a foundation for evidence to be applied Data Gathering: Hypothesis Driven Interview • Notice cues from patient –pattern recognition • Develop differential diagnosis • Collect target symptoms • Ask further questions to rule in or rule out Example: Chest Pain • Target symptoms – Chest pain, Shortness of Breath • Differential diagnosis – Cardiac (ischemic, valvular, cardiomyopathy) – GI (esophageal spasm, PUD) – Pulmonary (COPD, pleuresy, pneumonia) – Musculoskeletal (intercostal spasm, rib fx) • Further questions – Age, onset, associated symptoms, etc….. Example: Depression • Target symptoms: – Poor sleep, fatigue, isolation (no enjoyment) • Differential diagnosis: – Major Depression (single episode vs recurrent) – Dysthymia (2 year history) – Bipolar (mania/hypomania) – Substance induced mood disorder (mood during periods on abstinence) • Further questions: – Age, onset, associated symptoms, etc… Screening Strategies vs. Case Finding Strategies • High false positives if everyone screened • Practicing physicians think using casefinding strategies • High comorbidity • Different tools: – Interviewing questions – Diagnostic checklists – Disease specific scales How can a primary care doc make a reasonable psychiatric differential diagnosis? • Language: – Symptoms – Diagnostic categories • DSM-IV: – 6484 signs, symptoms, inclusion criteria – 405 diagnoses – 18 diagnostic categories • DSM-IV PC starts the process but is inefficient and “psychiatric” HELLO DATA GATHERING NEGOTIATION D A T A CUES HYPOTHESES (MAPSO©) G A T H E R I N G CASE FINDING QUESTIONS DIAGNOSTIC CRITERIA (DSM-IV) Comorbidities (ROS) DIAGNOSIS N E G O T I A T I O N TREATMENTS PATIENT PREFERENCE E PD AU TC IA ET N I TO N DIAGNOSIS & TREATMENT CHOICE MAPS-O ® MAPS-O® Mood Disorders Anxiety Disorders Psychotic Disorders Substance Abuse Other –“Organic” –Other Psych MAPS-O® • Most prevalent disorders in primary care • Proven treatments available • If “other” psychiatric disorder is diagnosed (somatization, personality disorders), • Then successful treatment requires diagnosing one of these categories first MAPS-O® Mood Disorders Anxiety Disorders Psychotic Disorders Substance Abuse Other MAPS-O® Mood Disorders Anxiety Disorders Psychotic Disorders Substance Abuse Other Major Depression, Dysthymia, Bipolar Disorder MAPS-O® Mood Disorders Anxiety Disorders GAD, Panic Disorder, PTSD, OCD, Phobias (Social/Specific) Psychotic Disorders Substance Abuse Other MAPS-O® Mood Disorders Anxiety Disorders Psychotic Disorders Substance Abuse Other Schizophrenia, Schizoaffective MAPS-O® Mood Disorders Anxiety Disorders Psychotic Disorders Substance Abuse Other Alcohol, Cocaine, Nicotine, Other Psychoactive Substances MAPS-O® Mood Disorders Anxiety Disorders Psychotic Disorders Substance Abuse Other “Organic”: Stroke, Dementia, HIV, TBI Other Psych: Personality Disorders, ADHD, Somatization,Eating Disorders MOOD DISORDERS Mood Disorders • Major Depression – Single episode – Recurrent • Dysthymia • “Double” Depression • Bipolar Disorder – Mania – Hypomania • Psychotic Depression EPISODE OF DEPRESSION RECOVERY OR REMISSION NORMAL MOOD DEPRESSION TIME 6 - 24 months 5-1 Stahl S M, Essential Psychopharmacology (2000) Mood Disorders – Major Depression 5 or more of the 9 symptoms at least 2 weeks (everyday, all day) –Depressed mood –Anhedonia –Worthless/Guilt –Death/Suicidal –Appetite –Sleep –Fatigue –Concentration –Psychomotor Major Depression – Questions: • How is your mood? • Have you been feeling sad, blue or depressed? • Have you lost interest in or do you get less pleasure from the things you used to enjoy? • Has there been any change in your appetite?
