The purpose of this study is to conduct a randomized control trial of a behavioral intervention delivered by nurses via an electronic medical record (EMR) patient web portal to determine if this is an efficacious method for supporting medication adherence.

Condition Intervention
Antiretroviral Medication Adherence Other: attention control Behavioral: adherence intervention

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Patient Portal to Support Treatment Adherence

Further study details as provided by Group Health Cooperative:

Primary Outcome Measures:
  • Lapses in medication adherence over the last 7 and 30 days (self report) and over previous 12 months (pharmacy records). [ Time Frame: 12 months ]

Secondary Outcome Measures:
  • Web service utilization. [ Time Frame: 12 months ]

Enrollment: 304
Study Start Date: June 2009
Study Completion Date: September 2012
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: staff emails
Attention control that includes staff sending emails with information about using health information technology system.
Other: attention control
9 informational email messages sent by study staff about the features of the shared electronic medical record system and how to use them.
Experimental: study nurse messages
A series of 6 proactive secure messages and 3 proactive booster messages (for a total of 9 secure and personalized messages) sent by the study nurse via the EMR patient web portal.
Behavioral: adherence intervention
9 messages tailored by the study nurse and guided by the IMB model

Detailed Description:
300 adult HIV+ patients will be randomized to one of two arms. 150 will be assigned to receive secure messages focused on antiretroviral adherence from a nurse through the health plan EMR patient website. 150 will be assigned to an attention control comparison arm, and will receive electronic messages from a study staff member that provide information about the various features of the health plan patient website. Patients will be invited by mail to be telephone screened for enrollment in the study. Patients will be provided the opportunity to opt out of being contacted by the study. Eligible and interested patients will be mailed an access code and separately emailed a link to a secure study website where they will complete a web consent form and a baseline web survey before being randomized to an intervention arm. This trial will allow us to evaluate the effectiveness of using health information technology as an intervention delivery vehicle to improve patient disease management behaviors such as treatment adherence.
