Major Depressive Disorder (MDD) One or more major depressive episodes Absence of any history of manic, mixed, or hypomanic episodes Relapsing and remitting Episodes may last months or, more rarely, years Half of all episodes fully remit within 6 to 12 months with or without treatment Up to 20% of those who experience an initial episode may develop chronic depression After an initial episode, the patient is predisposed to additional episodes which become more severe and last longer Moore DP, Jefferson JW. Mood Disorders. In: Moore & Jefferson: Handbook of Medical Psychiatry, 2nd ed. Philadelphia: Mosby; 2004
Depression Very common Associated with significant dysfunction Under diagnosed Often chronic or recurrent Commonly present with other GMC Highly treatable Multiple safe and effective treatments are available
Major Depressive Disorder Relapsing and remitting course • May eventually become chronic Minimum duration ≥ two weeks Clear distinction between episodes and inter-episodic function • Often well or at least much better between episodes
Two Questions Over the last two weeks: • Have you felt down, depressed, or hopeless? (Mood) • Have you felt little interest or pleasure in doing things? (Interest)
Two-Steps for Depression Screening Over the past 2 weeks have you felt down, depressed, or hopeless? Over the past 2 weeks have you felt little interest or pleasure in doing things? Probe deeper, be proactive, engage in conversation about mood and changes in behavior 24% - 40% of patients with positive screen receive MDD diagnosis Others may have dysthmia, subsyndromal depressive disorders, anxiety, PTSD, substance abuse, panic disorder, or grief disorder Step One: Two-Question Depression Screen Step Two: If Screen is Positive… A “yes” to either question is a positive initial screen for depression… US Preventive Services Task Force.

Visual Screening Tool Ask the patient to point to theface that best represents how she/hehas felt in the past 2 weeks. Depression in Women Series, PACE, 2007
Recommended Instruments • QIDS: Quick Inventory of Depressive Symptomatology (http://www.ids-qids.org) • PHQ-9: Patient Health Questionnaire-9(www.phqscreeners.com) Both instruments are… Validated Quickly and easily administered and scored Available to download Available in English and Spanish Helpful for initial screening AND evaluation of treatment response
SIGECAPS S I G E C A P S - Changes in sleep pattern - Changes in interests or activity - Feelings of guilt or increased worry - Changes in energy - Changes in concentration - Changes in appetite - Psychomotor disturbances - Suicidal ideation
Major Depressive Disorder Core symptoms: SIGECAPS • Depressed mood (sad, down, blue) AND/OR • Reduced interest or pleasure (I) Somatic symptoms: • Change in appetite (A) • Change in sleep pattern (S) • Reduced energy level (E) • Psychomotor agitation/retardation (P) Cognitive symptoms: • Poor concentration/easy distraction (C) • Inappropriate guilt/self reproach (G) • Thoughts of death, dying, suicide (S) 5 out of 9 for at least two weeks
The Suicide Question If an adult, child, or adolescent says, “I want to kill myself, or I'm going to commit suicide” Always take this statement seriously and immediately seek assistance from a qualified mental health professional People often feel uncomfortable talking about death. However, asking the adult, child, or adolescent whether he or she is depressed or thinking about suicide can be helpful. Rather than putting thoughts in the person's head, such a question will provide assurance that somebody cares and will give the person the chance to talk about problems
U.S. Suicides 11th leading cause of death 8th leading cause of death for males 19th leading cause of death for females 1.3% deaths suicide • 29% heart diseases • 23% malignant neoplasms • 6.8% cerebrovascular disease

Antidepressant Warnings All patients being treated with antidepressants for any indication should be monitored closely for: • Clinical worsening • Suicidality • Unusual changes in behavior Monitor these patients especially during the initial few months of a course of drug therapy, or at times of dose changes, either increases or decreases. Antidepressant Use in Children, Adolescents, and Adults http://www.fda.gov/cder/drug/antidepressants/default.htm
Practice Recommendation Base a choice of antidepressant on the patient’s prior response, patient and clinician preference, potential side effects, and cost. Choose any class of antidepressant as a first-line treatment for MDD. Ask patients from different ethnicgroups about their treatment preference for MDD. AAFP Approved source: National Guideline Clearinghouse. http://www.guideline.gov/summary/summary.aspx?ss=15&doc_id=9632&nbr=5152
Maintenance Patients with one lifetime episode of MDD who achieve remission on antidepressants should continue to take them for another 6 to 12 months. Patients with two or more episodes should be maintained an additional 15 months to 3 years. Patients with chronic MDD or MDD with concurrent dysthymia should be continued on antidepressants an additional 15 to 28 months after the acute phase treatment. Kaiser Permanente Care Management Institute. Depression clinical guidelines. http://www.guideline.gov/summary/summary.aspx?doc_id=9632&nbr=5152&ss=6&xl=999
Practice Recommendation Follow up with patients on antidepressants for MDD: • At least once within the first month • At least once more 4 to 8 weeks after the first contact Assess for adherence, side effects, suicidal ideation, and response. AAFP Approved Source: National Guideline Clearinghouse. http://www.guideline.gov/summary/summary.aspx?ss=15&doc_id=9632&nbr=5152 Strength of evidence: Consensus-based. A practice is recommended based on the consensus or expert opinion of the Guideline Development Team.
Practice Recommendation Advise patients that: Most people need to be on antidepressant medication for at least 6 months. It may take 2 to 6 weeks to see any improvement. It is very important to take the medication as prescribed, even after they start feeling better. They should not stop taking the medication without calling the provider first. Changing the dose or dose schedule can help manage side effects.

Steps for Choosing an Effective Antidepressant Recognize that some antidepressants may be more effective in certain populations even though most are generally of equal effectiveness. Ask about personal or family history of treatment with antidepressants, particularly about side effects. Consider the burden of side effects, particularly weight gain and sexual side effects in midlife women. Consider drug-drug interactions with other medications the patient is taking or may take. Consider the potential lethality of the antidepressant in the case of an overdose. Use antidepressant side effects for efficacy. Moore DP, Jefferson JW. Mood Disorders.

Other Options Include . . . Combine antidepressants and psychotherapy Increase dose of initial antidepressant Combine treatment with SSRI and low-dose desipramine (monitoring for TCA toxicity) Switch to different antidepressant of same or different class Augment with low-dose (300–600 mg/day) lithium in consultation with psychiatrist Switch from psychotherapy to antidepressants, or antidepressants to psychotherapy Kaiser Permanente Care Management Institute.

Treatment Goal The goal of treatment with antidepressant medication in the acute phase is the remission of major depressive disorder symptoms APA Practice Guidelines for the Treatment of Psychiatric Disorders.
Follow Up after Initial Treatment Follow up with patients on antidepressants for MDD: • Individualize visit frequency for each patient • Patient’s starting or switching to a new RX should be seen every two weeks until stable • Patient’s at increased risk for suicidality or self-injury seen more frequently • Contact all patients in early phase of treatment to assess for suicidality or self-injury • Assess response with validated tool Texas Medication Algorithm Project (TMAP) Treatment of Major Depressive Disorder Clinician’s Manual- http://www.dshs.state.tx.us/mhprograms/tmapover.shtm
Maintenance 50% of MDD patients will experience recurrence after initial episode without long-term treatment 3< episodes – maintain AD therapy as preventative Duration varies depending on risk factors from 1 year to lifetime Consider maintenance after 2 episodes for patients with high risk factors, PTSD, co-morbid anxiety, chronic depression or serious personality disorder Increased stressors may warrant longer maintenance Weilburg JB, O'Leary KM, Meigs JB, Hennen J, Stafford RS.
