Advancing Biopsychosocial Care Training Initiative

This project will compare two training approaches for US Preventive Services Task Force recommended obesity care in Federally Qualified Health Centers (FQHC) across four aims. Aim 1 compares patient-level effectiveness [i.e., patient relative weight change and the proportion of patients who achieve clinically significant weight loss]. Aim 2 compares reach (patient treatment utilization). Aim 3 compares primary care provider (PCP) referrals to USPSTF-recommended care at 12 (adoption) and 24 months (maintenance) and short- and long-term changes in provider obesity care competencies . Aim 4 compares implementation and service costs.

Treatment and study plan

Comprehensive Multidisciplinary Obesity Care

Other

CMOC is an innovative approach to obesity care delivery that leverages policy, clinical and community linkages, and digital technology for scalability. CMOC involves training providers (medical providers, registered dietitians, and behavioral health providers) to deliver guideline-based obesity care for youth and adults with obesity who receive Medicaid. Guidelines-based care involves screening, identification, weight counseling, and referral to intensive behavioral treatment by medical providers, and delivery of multicomponent intensive behavioral treatment by behavioral health providers and registered dietitians.

Other names: Core+

Implementation as Usual Control

Other

The standard of care implemented in FQHCs in the absence of CMOC training.

Other names: Core

Primary outcomes

  1. Change in patient percent overweight

    Time frame: Months 2-29 post-enrollment
