  2. Translating Positive findings in Aging to Younger Adults

  3. Disclosures • NIMH • K08 Award • ACSIR • NIDA • Center for Studies on Addiction • NIAAA • R01 • VA • Merit Early Entry • MIRECC • HSRD Merit Award • Industry Support • DuPont Pharma • Forest Labs • Hazelden Foundation • Pfizer

  4. Relevance of comorbidity to an aging population • Cohort changes in exposure – we will see more elderly patients using illicit substances (current and past abuse) • Consequences may be greater in older adults • Direct toxicity / withdrawal • Indirect interactions with medications or other illnesses • Comorbidity is a significant issue perhaps uniquely so for the elderly • Cognition • Minor depression • Suicide • Anxiety and personality problems • Changing environment • Social isolation • Limited resources • Limited access to care

  5. Comorbidity and Drug/Alcohol Dependence • Higher than expect rates in representative community samples • Markedly higher rates in treatment seeking samples • Increased morbidity and mortality particularly suicide • Presents diagnostic difficulties • Poor prognostic factor • Call for integrated care system

  6. Suicide • Highest rates of suicide occur in late life among men. • Depression causes a 5.8 fold increase in risk of suicide compared to death from other causes • Heavy drinking (3+ drinks/day) causes a 8.9 fold increase in risk of suicide compared to death from other causes • Moderate drinking (1-2 drinks/day) causes a 10.6 fold increase in risk of suicide compared to death from other causes Grabble, et al. 1997

  7. The difficulty • Extremely limited research • Drug and alcohol dependence are exclusions to most geriatric trials • Age >65 is almost always an exclusion for drug and alcohol trials

  8. What is the Extent of the Issues?In the Community

  9. Baby Boomers Aging Grant, et. al. Drug and Alcohol Dependence 2004

  10. Veterans (Age 60 and Over) in Addiction Treatment Alcohol Only 51.8% Street Drugs Only 9.1% Prescription Medications only 3.6% Alcohol and Street Drugs 26.4% Alcohol and Prescription Medications 5.5% Street Drugs and Prescription Medications 0.9% All three categories of substances 1.8% Missing data 0.9% Sample of 110 subjects in a special geri-addiction program Schonfeld et al. 1990

  11. Past History of Heavy drinking/alcoholism • Many older adults especially those of the “Woodstock” generation will enter late life with a past history of alcohol or drug abuse • 5 fold increase in late life mental disorders (depression and dementia) • Treatment of late life depression (3-5 yr outcomes) • 88% of those without an alcohol history significantly improved • 57% of those with an alcohol history significantly improved Saunders et al. 1991, Cook et al. 1991

  12. Behavioral Health Laboratory (BHL): Links To Primary Care

  13. Research to Practice:Behavioral Health Laboratory • The BHL is an automated telephone assessment and triage service for patients identified by primary care providers as having depressive symptoms or at-risk drinking. • The depression and alcohol clinical reminder system generates a consultation request to the BHL. • The BHL conducts a brief telephone (20-30 minutes) assessment generating a report for the PCP including diagnosis, severity, and general treatment recommendations.

  14. Drug Use Among Primary Care Patients with Minor or Major Depression

  15. Types of Substance Use Among Older Adults (50+)

  16. Drug Use Among Older Patients with Minor or Major Depression

  17. Treatment

  18. Depression Alcohol Aging Trial • Hypotheses • Among older adults with major depression and comorbid alcoholism, naltrexone combined with sertraline improves the outcomes of both drinking and mood. • Reduction in alcohol consumption will be associated with improved mood regardless of randomization. • Naltrexone will lead to a reduction in alcohol consumption independent of changes in mood.

  19. Concurrent Treatment of Depression Complicated by Alcohol Dependence • Current depressive syndrome • Current alcohol dependence • Age 55 and over • 10 sessions of compliance enhancement therapy • 1/2 of subjects are randomly assigned to receive naltrexone 50 mg • All subjects receive sertraline 100 mg • Outcomes at 3 months (Oslin, 2004)

  20. Pre-Treatment Clinical Characteristics

  21. Relationship between heavy drinking during the trial and depression outcomes

  22. Overall Treatment Outcomes

  23. Substance Induced Depression in the elderly? • Less than 50% resolution of symptoms early in treatment • No relationship between clinical impression of primary vs. secondary depression and early response

  24. Not just Dependence • Moving beyond DSM in conceptualizing risk

  25. Disease and Behavior • Substance dependence • Follows the biomedical model of an illness • At-risk use • Public health model • Recognizes risks (health, economic, etc.) associated with use in individuals not suffering with the “disease” • Most relevant for alcohol, medications, marijuana and nicotine.

  26. What about moderate or abusive drinking (non-dependent drinking) • Most common pattern of drinking among those with depression • May be beneficial for heart disease • Safety concerns may be less with newer medications (SSRIs) than older meds (TCAs)

  27. Response to Standard Depression Care Among the Elderly • PROSPECT study • Remission of depression (men only) • Non-drinkers – 41 % • Moderate drinkers – 18.2% • PRISM-E study (preliminary) • Remission of depression (men only) • Non-drinkers – 33.8 % • Moderate drinkers – 6.3 % (Personal Communication, 2002)

  28. Telephone Disease Management for Depression and At-Risk Drinking • To develop a method for delivering high quality depression and alcoholism treatment in Primary Care, CBOCs, and other clinics in which there are significant transportation, staff resource, or other impediments to the delivery of face-to-face MH/SA care. • To develop methods for translating effects demonstrated in randomized clinical trials to clinic populations.

  29. Treatments • Telephone Disease Management is algorithm driven care delivered by a Behavioral Health Specialist. • Enhanced Usual care. The PCP can monitor, treat, and/or refer. The PCP is provided a diagnosis and references for treatment options.

  30. Improvements with TDM Oslin, et. al. 2003

  31. Is Sedative/Hypnotic Use a Co-Occurring Problem? • Association with falls • Association with memory impairment • ?Association with treatment of depression

  32. How to Define Inappropriate Benzodiazepine Use • Chronic Use (>3 months) • Use of long-acting agents • Undocumented response • Lowest effective dose (harm reduction)

  33. Sedative/Hypnotic UseA Disappearing Problem? M:W p= 0.0393, Positive: Negative p=0.002

  34. Types of Sedative/Hypnotics Used
