Official title

Antidepressant Adherence Via Telephonic Interactive Voice Recognition (IVR)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
