Antidepressants are the most frequently prescribed class of psycho¬tropic medications and the most common treatment for depression and anxiety disorders—yet patient adherence is poor and is widely viewed as contributing to reduced effectiveness. However, traditionally-delivered adherence promotion programs are complex, staff-intensive, and costly—barriers to wider adoption, implementation, and maintenance of these programs in real-world settings. Our aim is to carry out a trial of a low-cost, IT-enabled Antidepressants adherence program, specifically a direct-to-patient, automated telephone interactive voice recognition (IVR) intervention to boost patient Antidepressants persistence. We will conduct a randomized clinical trial enrolling at least 6,000 Kaiser Permanente NW Region health plan members ages 21 to 75, who had recently started on Antidepressants medications for depression and/or anxiety diagnoses. Participants will be randomized one of four arms;1. a no contact control arm, 2. a treatment as usual (TAU) control condition 3. to TAU plus the IVR automated telephone program and 4. a TAU plus the IVR automated telephone program plus receipt of psycho-education materials about antidepression medication use. Recruitment will continue for up to 18 months, with periodic participant-level follow-up assessment for the intervention participants for 40 weeks. The IVR intervention portion of the program will deliver reminder and/or tardy calls timed to projected Antidepressants refill dates. The intervention also optionally offers brief psycho-education, or transfer to a live pharmacist or the Kaiser mail refill pharmacy. The primary outcome will be the Estimated Level of Persistence with Therapy (continued us of Antidepressants medications). This will be based on prescription refill data abstracted from the Kaiser's electronic medical record (EMR). We hypothesize that participants in the IVR + psycho-education materials study arm will have a significantly higher rate of Antidepressants persistence than those in the TAU control condition ons only IRV call arms. We will also conduct cost-effectiveness analyses to assess the value-for-money (cost per depression free day gained, and cost per quality adjusted life year gained) of the IVR technology compared to TAU. Costs will include IVR development and implementation as well as EMR-derived healthcare utilization data (visits, medications, etc.), augmented with participant report of out-of-plan services.

Eligibility |
Inclusion Criteria: - Participants must be Kaiser Permanente NW Region health plan members ages of 21 and 75 and be members for at least 6 months prior to the initial antidepressive medications dispense. - Participants must have an EMR chart diagnosis or presenting complaint of a unipolar mood diagnosis, anxiety disorder, or any subclinical or "not otherwise categorized" (NOC) variant of these. - The participants' providers must give permission to study staff for their patients' enrollment in the study. There must be no indication of pending HMO disenrollment in the membership data. - Participants must have an initial dispense of an antidepressant medication, with no dispense of any of these agents in the prior 6 months. Exclusion Criteria: - Participants must have no EMR chart diagnosis that is likely to impair participant ability to complete evaluations or take part in the intervention. These include psychiatric diagnoses such as bipolar disorder I (BP II is acceptable), schizophrenia, schizo-affective disorder, or similar diagnoses indicating psychosis. - The investigators will also exclude individuals with any chart diagnosis indicating significant intellectual impairment, such as any dementia disorder, mental retardation, or profound developmental disorder such as autism. |

Primary | Participants in the IVR study arm will have a significantly higher rate of AD persistence (ELPT) than those in the TAU control condition | A randomized controlled trial of adult members of a (HMO) starting an incident episode of antidepressant treatment, (a) nocontact control,(b) treatment as usual (TAU) versus (c) TAU plus the IVR automated telephone adherence program, (d)TAU plus the IVR automated telephone adherence program plus mailed psycho-education materials. The primary outcome will be antidepressant persistence, operationalized as the Estimated Level of Persistence with Therapy. Secondary outcomes will include patient and provider satisfaction, healthcare utilization, and patient self-reported depression and anxiety. | assessments at 4, 8,12 and 40 weeks | No |
Secondary | cost-effectiveness analyses | We will also conduct cost-effectiveness analyses comparing the arms of the study. We will employ healthcare utilization data (visits, medications, etc.) obtained from the electronic medical record, augmented with participant report of out-of-plan healthcare services. These will compare study conditions on the cost to achieve units of improvement in depression free days and quality-adjusted life years. We expect that costs per unit of improvementfor the IVR intervention will be within standard boundaries of decision-makers willingness to pay. | at the end of week 40 | No |
