Brief Summary

The investigators will conduct a phase I study involving 41 participants selected randomly among patients prescribed buprenorphine-naloxone for opioid misuse as a feasibility trial of the study of the Pillsy device. The study will track the effectiveness of the Pillsy technology and associated smartphone application by measuring adherence to buprenorphine-naloxone therapy and patient satisfaction with the application and the Pillsy device.

Detailed Description

The purpose of this randomized, controlled trial in Phase I is to determine whether the Pillsy intervention can improve adherence to buprenorphine-naloxone compared to Service As Usual.

This will be a collaborative study between WSU, Pillsy, Inc, and the clinical site Ideal Options (opioid use and other substance use disorders treatment center). The overarching goal is to evaluate if the use of the Pillsy system will improve treatment adherence. The study coordinator will work closely with the clinical site, conducting a scripted screening, by phone or in person, documenting substance use, addiction treatment history, medical and psychiatric history, medication, addiction treatment goals, and availability of social support.

The Pillsy device is a smart cap that tracks pill bottle openings and uses lighted reminders to prompt patients when to take their medication. The Pillsy Helper feature is a smartphone application that sends text and phone reminders as well as links to the participant named family and friend support networks. The Pillsy Helpers feature allows participants to name friends and family members who will also receive a text message notification 1 hour after a missed dose to reach out to offer support. In addition, the prescriber will be contacted when the patient has missed a dose, giving the prescriber the opportunity to intervene. Study participants will be randomized to one of two groups. The control group will receive the Pillsy cap alone. The active group will receive the Pillsy cap and smartphone application with associated benefits. To measure adherence, all participants will provide a urine sample at each study visit and complete a questionnaire (ex: AUDIT, Fagerstrom, Addiction Severity Index, Timeline Follow-Back) and survey that assesses their satisfaction with treatment.

Study Groups

Pillsy arm

Participants in the Pillsy arm will receive a prescription for buprenorphine-naloxone with an ''active'' Pillsy smart cap that will continuously collect data on pill bottle openings, missed doses, text messages sent, automated phone calls made. A participant who misses an entire day of buprenorphine-naloxone will automatically receive a survey about cravings and risk of relapse.

Group Type: ACTIVE_COMPARATOR

Reminders messages to improve adherence.

Intervention Type: BEHAVIORAL

If the participant does not take their medicine at the correct time, a light on the smart pill cap begins to flash. If the bottle is not opened within 20 minutes, the Pillsy application sends an SMS text reminder to the participant's phone. If the bottle is not opened within 60 minutes, the participant receives an automated phone call. The participant may also receive brief motivational phrases or craving surveys that can be tailored to participant needs and preferences. Also, based on pre-populated and adjustable craving and withdrawal levels, the participants' provider could be contacted automatically based on the thresholds being crossed. Pillsy also includes a "Pillsy Helpers" feature in which the patient can name friends and family members who will also receive a text message notification one hour after a missed dose.

Service as usual arm

Participants in the Service As Usual arm will receive a prescription for buprenorphine-naloxone with an ''inactive'' Pillsy smart cap that will track openings but will not provide reminders or any other messaging. They will receive a basic application that can deploy patient satisfaction surveys.

Group Type: NO_INTERVENTION

No interventions assigned to this group
