Brief Summary:
The C3PO pilot and feasibility study uses a rigorous, mixed-method research design to provide information needed to refine and implement a technology-mediated primary care outreach intervention approach before conducting a larger and more definitive future intervention trial.

Detailed Description:
This study will implement and evaluate a pragmatic and generalizable framework for population management of obesity by the primary care sector. With patient and other stakeholder input, the C3PO intervention will be designed to leverage existing primary care professionals and technologies to implement a scalable framework for population obesity management that coordinates primary care services with extant intensive lifestyle interventions in community settings to achieve wider reach and population-level effectiveness. A rigorous, mixed-method pilot and feasibility study will provide critical information needed to optimize the intervention design and prepare us for a larger and definitive future trial.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 80 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: The active intervention "C3PO" involves enhanced use of pragmatic electronic health record system technologies and members of the primary care workforce to increase supportive accountability and problem solving support for weight loss goals and behavior, which in turn will lead to routine self-weighing, increased take up into intensive community programs, and increased adoption and maintenance of healthy eating and physical activity behaviors that collectively lead to greater weight loss at a population level.
Masking: Double (Investigator, Outcomes Assessor)
Masking Description: Patients will be randomized to either Basic Resources and Services or the C3PO intervention arm. Although patients will be aware of the specific forms of support they are receiving throughout the trial, each individual will not be aware that they are part of a randomized experiment and will not know that other patients may be receiving different levels of support. For this reason, the non-concealed nature of the behavioral support intervention for participating patients should not introduce bias. Investigators and outcome assessors will not be aware of intervention assignment during the study conduct or evaluation phase.

Arm Intervention/treatment
Active Comparator: Basic Resources and Services
Patients will receive outreach engagement in goal setting via MyChart, an electronic scale, telemonitoring of self weighing, and information about linkages to extant intensive lifestyle interventions in the community
Behavioral: Outreach Support for Weight Loss Goal Setting and Self-Weighing
Patients will receive a MyChart activation message assessing weight loss interest that invites them to complete a MyChart Survey encouraging a weight loss goal using principles adapted from Brief Action Planning. Patients will then receive a cellular network-enabled electronic body weight scale, and weighing data transmitted by the scale will be received and integrated into the electronic health record for access by the patient's primary care team.

Behavioral: Outreach Decision Support to Encourage Linkages to Intensive Community Lifestyle Interventions
Patients will receive via MyChart information and decision support designed to encourage linkages to and participation in intensive lifestyle programs available in the community. Patients who request information or clinical referrals will also receive them. "Refreshes" of community linkage information will be sent by MyChart every 1 to 4 weeks.

Experimental: Coordinated Primary Care Population Management (C3PO)
Patients will receive outreach engagement in goal setting via MyChart, an electronic scale, telemonitoring of self weighing, information about linkages to extant intensive lifestyle interventions, and outreach MyChart messages that are tailored to each individual's pattern of self-weighing and progress towards their weight goal, and more intensive support from a primary care nurse based on self-weighing behavior and weight loss success.

Behavioral: Adaptive Tailoring of Information Delivery and Intensity of Primary Care Outreach Support
Data received into the electronic health record from the cellular network-enabled electronic scale will categorize each patient based on their daily self-weighing behaviors and rate of progress towards their weight loss goal. Patients who are not engaged in daily self-weighing or are not making progress towards their goal will receive more intensive outreach support in the form of automated weekly MyChart problem solving messages, more frequent encouragement to access a broader array of community resources, and telephonic support from a nurse care coordinator who is an existing member of the primary care team. Support from this nurse care coordinator will be facilitated by the incorporation of each patient's self-weighing data into an EpicCare patient dashboard accessible to the nurse coordinator and other members of the care team
