Anxiety/Depression

Lauren Waskowicz

Background 

  • Anxiety disorders: spectrum of disorders characterized by excessive fear, anticipatory anxiety of future threat, or avoidance behaviors
    • Includes generalized anxiety disorder (GAD), panic disorder, social anxiety disorder, specific phobias, substance-induced anxiety disorder
  • Mood disorders:
    • Include major depressive disorder (MDD), bipolar disorder (BPD), seasonal affective disorder, dysthymia

Presentation 

  • MDD: 2+ weeks of ≧ 5/9 SIGECAPS (sleep, interest, guilt, energy, concentration, appetite, psychomotor, suicide), or PHQ-2 screen >2 / PHQ-9 score > 4
  • GAD: 6+ months of anxiety and associated restlessness, fatigue, impaired concentration, sleep disturbances (use GAD-7 tool to assess)

Evaluation 

  • Screen for personal and family history of substance use disorders (often comorbid with mood disorders)
  • Screen for family members with MDD/GAD, and if positive, which SSRIs have worked (genetic component of responsiveness)
  • Screen for suicidal ideation (“Have you ever had thoughts about wanting to be dead? Not wanting to wake up?”)
    • If “yes,” assess for active/passive (“in the past week, have you had any actual thoughts of killing yourself?”), plan/intent (“do you have a plan to kill yourself and do you have intent to act on them?”)
    • Ask about prior psychiatric hospitalizations o Ask about firearms in the house
  • Screen for periods of mania (“have you ever felt like you have needed <3-4 hours a night of sleep?”) as this is a contraindication for SSRIs (below)
  • PHQ-9 > 4 abnormal, >9 consider therapy +/- pharamcotherapy

Management

  • No psychotherapy offered through VUMC. Counsel to call insurance customer service and ask for in-network counselors accepting new pts. Can also recommend psychology today website ( https://www.psychologytoday.com/us) for assistance in finding therapy based on insurance coverage (.PSYCHTODAY)
    • EPIC dot phrase for Nashville therapists (who have accepted OHO pts in the past): .CTLPSY-CHRESOURCES and .LRWPSYCHCOMMUNITY
  • Persons in crisis: for pts expressing active suicidal ideation with intent, can refer to:
    • Centerstone (TN crisis line): (800) 681-7444
    • Mental Health Cooperative (emergency line): (615) 726-0125
