1. 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

2. 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

3. Outline PIPC 1 –Introduction –PIPC ® Interview –MAPS-O ® –Mood Disorders –Suicide

4. Outline PIPC 2 –Anxiety Disorders PIPC 3 –Neurotransmitters –The 3 Phases and the 5Rs –Medications –Cases and Discussion

5. “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

6. 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)

7. PIPC ® Interview

8. 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

9. 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

10. 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…..

11. 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…

12. Screening Strategies vs. Case Finding Strategies High false positives if everyone screened Practicing physicians think using case- finding strategies High comorbidity Different tools: –Interviewing questions –Diagnostic checklists –Disease specific scales

13. 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”

19. 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

26. MOOD DISORDERS

28. Mood Disorders Major Depression –Single episode –Recurrent Dysthymia “Double” Depression Bipolar Disorder –Mania –Hypomania Psychotic Depression

29. DEPRESSION NORMAL MOOD RECOVERY OR REMISSION EPISODE OF DEPRESSION TIME 6 - 24 months 5-1 Stahl S M, Essential Psychopharmacology (2000)
