Title: Randomized Trial of Liaison Psychiatry in Primary Care
Brief Summary: This study will evaluate the effectiveness of a nurse-led case management intervention in improving disease control and depression symptoms in adults with diabetes and/or heart disease who are also depressed.


Options:
A: Inclusion Criteria:

* Diagnosis of type 2 diabetes mellitus (HgA1c\>7%), requiring the patient to take at least one tablet per day or one insulin injection per day and a diagnosis of hypertension (130/80) requiring them to take at least one medication per day;
* Participants must identify themselves as African-American;
* Participant resides in or proximal to the North Lawndale neighborhood;
* Secure written permission from their physician to engage in moderate physical activity. This set of participants may be at high risk for cardiac disease and this exclusion avoids putting them at undue risk;
* BMI ≥ 25. Participant must be overweight because the main goal of our intervention is weight loss of 5% or more of initial body weight.

Exclusion Criteria:

* Diet-controlled diabetes;
* Hypertension controlled with lifestyle modification only;
* Endstage renal disease, stroke with paresis, congestive heart failure (NYHA class 3 or 4), or other major endorgan complication of diabetes;
* Comorbid conditions limiting probable life span to \<4 years (e.g. cancer, AIDS) or indication of end-stage complications of diabetes (kidney dialysis, or transplant, blindness, or lower extremity amputation);
* Receiving treatment for a major psychiatric disorder (i.e. schizophrenia);
* Unable to give informed consent;
* Are under the age of 18-While type-2 diabetes and hypertension are increasing in those under the age of 18, adolescent medicine is a separate specialty area from adult medicine. Interventions should be targeted specifically toward this age group to take into consideration the specific emotional and psychological needs of adolescents;
* Alcoholism as measured by the CAGE.screener for alcohol abuse.
B: Inclusion Criteria:

* Veterans with comorbid diabetes and depressive symptoms receiving primary care services at VA CBOCs throughout Southeast Texas
* as well as MEDVAMC patients living \>20 miles from the hospital who face similar distance related treatment barriers

Participants must have:

* a diagnosis of diabetes mellitus
* an average HbA1c level \>7.5% in the prior 6 months
* clinically significant symptoms of depression
* Verification of diabetes mellitus diagnoses will be based on data collected from the VA data warehouse.
* To verify that participants meet the depression criteria, the investigators will use participant self-report of clinically significant depressive symptoms according to the PHQ-9, where a score of greater than/equal to 10 on the PHQ-9 will signify a clinically meaningful symptom burden.

Exclusion Criteria:

* The investigators will exclude potential participants only for clinical factors that would render a telephone-based behavioral activation intervention inappropriate.
* Specific exclusion criteria are:

  * lack of regular access to a telephone
  * significant cognitive impairment (three or more errors) on an established six-item screening exam
  * meeting criteria for bipolar, psychotic, or substance-abuse disorders
  * presence of uncorrected hearing or vision impairment
  * their medical chart recommends not titrating therapy due to prior history of significant hypoglycemic events
  * they live within 20 miles of the MEDVAMC.
* Patients will be secondarily excluded if their HbA1C level falls below 7.5% at baseline assessment, or if they report suicidal ideation on the PHQ-9 at baseline assessment.
* Patients receiving mental health services at the time of study recruitment will not be excluded.
* All mental health treatments and health service-use characteristics will be included in study analyses as covariates.
C: Inclusion Criteria:

* patients aged 65 years and older
* must have a minimum of three chronic or vitality threatening diseases and/or use five or more medical drugs chronically in the last year
* must have dyspnea and/or reduced exercise tolerance (scored by two short questionnaires)

Exclusion Criteria:

* patients with both confirmed COPD and heart failure (Spirometry performed \< 1 year ago and heart failure confirmed by echocardiography)
* patients unable or unwilling to sign informed consent
D: Inclusion Criteria:

* Diagnosis of diabetes and/or heart disease
* Poor disease control (defined as an HbA1c level of at least 8.5%, blood pressure greater than 140/90 mm Hg, LDL cholesterol greater than 130 mg/dL)
* Diagnosis of major depressive disorder

Exclusion Criteria:

* History of psychosis
* At high risk for suicide
* Cognitive impairment
* Current alcohol or substance abuse disorder
* Does not own a telephone
* Currently seeking psychiatric care
* Pregnant or breastfeeding
* Currently enrolled in a Group Health Cooperative disease management program
