Sub-study descriptions involved in needs assessment.

Sub-study	Procedures
On-site primary care staff interviews regarding the MA referral process and coaching in 4 study clinics Sample size: 24 MAs and 5 RNs	An interview was conducted with semi-structured questions regarding the proposed program, perceived usability of the proposed prompt, usual workflow, and provider-staff communication methods (Supplementary Appendix A).
On-site primary care administrator interviews in 4 clinics Sample size: 3 clinic administrators	We presented the MAINTAIN PRIME program to clinic administrators and asked them to describe the clinic approval process and any concerns or suggestions that they had in implementing the program. Usual workflow, communication patterns of providers and staff, staffing concerns and adjustments to COVID were discussed (Supplementary Appendix B).
Provider interviews via Zoom in 4 clinics Sample size: 20 providers who had (1) relatively high rates of referrals to dietitians; (2) identified as opinion leaders; and (3) were active in already existing wellness programs were selected.	A 1:1 interview using a critical incident approach with semi-structured questions was used. Providers described a specific patient with whom they had a recent weight management conversation, their clinical goals with that patient, information needs, and usual data collected. The proposed intervention was then presented, and a short usability interview was conducted to review the provider-facing referral prompt prototype (Supplementary Appendix C).
