• Registration Number: NCT02583230
• Lead Sponsor: Northwestern University

Brief Summary

The goal of this project is to develop and pilot a mobile smartphone delivered intervention that will improve antidepressant medication care by providing medication adherence monitoring and support to the patient, feedback on patient adherence and response to treatment to the primary care team, and information to both patients and providers on guideline-congruent care personalized to the patient's response to antidepressant medication.

Detailed Description

Major depressive disorder (MDD) is common and imposes a very high societal burden in terms of cost, morbidity, suffering, and mortality. While primary care is the de facto site for treatment of MDD, outcomes in primary care are poor. Two principal reasons for the poor outcomes in primary care are poor patient adherence to antidepressant medications (ADMs) and the failure of physicians to provide guideline-congruent care. This problem is aggravated by a lack of communication between patients and the care team.

A growing body of research indicates that primary care-centered strategies aimed at enhancing guideline-congruent care have not been effective. Interventions aimed at improving adherence in the patient have been successful in changing patient adherence behavior; however these frequently fail to improve depression outcomes, particularly when there is no intervention on the physician side to encourage optimization of ADMs. Recent developments in information and communications technologies (ICT) have opened new opportunities to improve health and mental health care, and to link patients and their providers. This study harnesses these advances to develop and pilot a system where ADM adherence will be passively measured using an electronic pill dispenser. The dispenser is connected to a mobile smartphone via Global System for Mobile Communications (GSM), so that targeted, timely reminders can be provided when the patient fails to take the ADM. When the patient is adherent, the patient will not be bothered with reminders. Depressive symptoms and side-effects will be periodically monitored weekly via the phone. Every 4 weeks, or if indicated (e.g intolerable side effects or urgent situations), primary care teams will receive notifications via the electronic medical record that include a summary of patient data on treatment response and side effects, guideline-congruent treatment recommendations based on patient data and a recommendation to contact the patient, if indicated. Simultaneously, a similar message will be provided to the patient, including feedback, possible treatment options, and a recommendation to contact the physician's office. Thus, both the patient and care team will be activated to provide, request and adhere to guideline-congruent care.

The aim of this 8 week field trial is to develop and pilot the MedLink system. Development will employ an iterative user-centered approach. Primary outcome will be patient adherence; secondary outcomes will be depression, system use, and usability and satisfaction.

Arm && Interventions

Group	Intervention	Description
MedLink	MedLink System	For 8 weeks, the patient who is newly prescribed antidepressant medication will receive a mobile phone app (and a phone if they do not have a compatible Android phone) and a GSM enable pill bottle in order to provide and receive feedback regarding medication adherence.

Primary Outcome Measures

Name	Time	Method
Adherence to Antidepressant Medication	8 weeks	Number of days medication was taken when a dose was expected. Measured through % of days adherent on Wisepill pillbox as well as 2. Self-reported adherence: Patient Adherence Questionnaire (PAQ).

Secondary Outcome Measures

Name	Time	Method
Patient Health Questionnaire-9 (PHQ-9)	Baseline, Week 4, and Week 8	The PHQ-9 measures degree of depression severity. Possible range of scores for the PHQ-9 is 0-27. Higher values represent a worse outcome. Specifically, scores of 0-4 indicate minimal or no depression; 5-9 is mild; 10-14 is moderate; 15-19 is moderately severe; and 20-27 is severe.
Quick Inventory of Depressive Symptomatology Clinician Rating (QIDS-C)	Baseline, Week 4, and Week 8	This measure assesses depressive symptom severity. The total score is obtained by adding the scores for each of the nine symptom domains of the DSM-IV MDD (major depressive disorder) criteria: depressed mood, loss of interest or pleasure, concentration/decision making, self-outlook, suicidal ideation, energy/fatigability, sleep, weight/appetite change, and psychomotor changes (Rush et al. 2003). Sixteen items are used to rate the nine criterion symptom domains of a major depressive episode. Each item is rated 0-3. For symptom domains that require more than one item, the highest score of the item relevant for each domain is taken. The total score ranges from 0-27. Higher values represent a worse outcome. Specifically, scores of 0-5 indicate no depression; 6-10 is mild; 11-15 is moderate; 16-20 is severe; and 21-27 is very severe.
