Primary care nutrition training is widely recognized as inadequate for the practical needs of clinicians, and educators and clinical researchers need evidence to redesign curricula and systems. According to the PLOS One study by Hildebrand et al. (2026), 32 primary care physicians were interviewed to map gaps across training, clinical practice, and collaboration with dietitians. This post translates that qualitative evidence into actionable implications for medical educators, health services researchers, and qualitative teams, and shows how AI-enabled qualitative research methods can accelerate synthesis, reproducible coding, and cross-segment comparisons to inform curriculum and system reform.
Key Takeaways
According to the PLOS One study by Hildebrand et al. (2026) PLOS One, primary care physicians report that nutrition belongs in primary care but training, time, and dietitian access make consistent, actionable counseling rare.
- 32 primary care physicians were interviewed between September 2023 and March 2024, according to Hildebrand et al., PLOS One (2026).
- Of 59 initiated recruitment surveys, 52 were completed and 47 were eligible, with interviews conducted after initial recruitment emails beginning on August 23, 2023 and reminders through February 9, 2024, according to PLOS One (2026).
- According to PLOS One (2026), 50% of participants were family physicians and in Table 1 41% reported being "somewhat" confident and 34% "fairly" confident addressing nutrition in clinical practice.
- According to Hildebrand et al., PLOS One (2026), PCPs named four interrelated problems in July 2026: unclear PCP role, insufficient training and frameworks, weak interprofessional collaboration with dietitians, and system/societal barriers.
What Happened: the PLOS One qualitative study and methods
The PLOS One study by Hildebrand et al. (2026) interviewed 32 primary care physicians to understand training, practice, and collaboration barriers for nutrition counseling.
According to Hildebrand et al., PLOS One (2026), semi-structured interviews ran from September 2023 to March 2024, averaged 28 minutes, and were transcribed and coded using Dedoose software with two coders establishing codebook reliability.
According to PLOS One (2026), recruitment began with 412 alumni emails and the study moved from screening surveys (59 initiated, 52 completed) to purposive interview scheduling, yielding 32 interviewed PCPs who graduated UNC School of Medicine (classes 2015–2023).
According to Hildebrand et al., PLOS One (2026), analysis combined episode profiles, cross-participant matrices, and thematic content analysis to produce a conceptual framework of four overlapping problems and illustrative participant quotes, for example a PCP who said, "I can’t remember it in med school…it’s not really coming back to me as like a specific block or something."

|---|---|---|---|
| Aug 23, 2023–Feb 9, 2024 | Recruitment invitations and reminders | 412 emails sent; 59 initiated surveys; 52 completed; 47 eligible | Recruitment concentrated on UNC SOM graduates; limits generalizability but yields detailed end-user data |
| Sept 2023–Mar 2024 | Interviews completed | 32 PCP interviews; average duration 28 minutes | Rich, in-depth qualitative data for design-thinking problem definition |
| Table 1 (reported in study) | Specialty mix | 50% family physicians; nearly half see adult and pediatric patients | Cross-spectrum primary care perspectives captured |
| Study reporting (published Jul 31, 2026) | Self-reported confidence | 41% somewhat confident; 34% fairly confident addressing nutrition | Highlights a training and confidence gap that curriculum redesign should target |
| Study conclusions (published Jul 31, 2026) | Identified problem domains | Four overlapping problems: role clarity, training/frameworks, RD collaboration, system/societal barriers | Use guiding frameworks and interprofessional models to break the cycle |
Implications for medical educators and qualitative researchers
The PLOS One study by Hildebrand et al. (2026) implies that educators must define realistic PCP competencies and teach brief, actionable nutrition counseling framed for 10–15 minute visits.
- According to PLOS One (2026), physicians often learned nutrition ad hoc, so medical educators should map a minimal, prioritized competency set (e.g., brief dietary assessment, one concrete recommendation, and an RD referral trigger) and measure those competencies longitudinally.
- According to Hildebrand et al., PLOS One (2026), interprofessional education with dietitians should be formalized because 64% of family physicians in related surveys previously reported not having an on-site RD, indicating structural access problems.
- According to PLOS One (2026), system-level barriers such as 15-minute visit templates and food environment constraints require policy and delivery-model experiments (for example, co-visits, tele-dietetics, or shared appointments) to test feasibility and equity.
How Evidano Helps: from transcripts to teachable insights
Evidano for qualitative synthesis
Evidano is an AI-powered qualitative data analysis platform that helps researchers analyze interviews, open-ended surveys, and documents.
Evidano can accelerate reproducible coding of interview transcripts like those in the PLOS One study by supporting hierarchical codebooks, co-occurrence networks, and exportable episode profiles to compare approaches across clinician subgroups; see Evidano features.
Problem: Variable, inconsistent advice → Feature: Thematic + cross-segment analysis
According to the PLOS One study (Hildebrand et al., 2026), PCPs described inconsistent nutrition approaches learned informally; Evidano’s thematic and cross-segment analyses let teams quantify topic frequency and map which trainee cohorts mention specific counseling steps.
Evidano’s episode profiles reproduce the study’s approach programmatically so educators can compare trainees by graduation year, specialty, or self-reported confidence and spot training gaps at scale.
Problem: Limited time and resources → Feature: Rapid extraction and templates
According to PLOS One (2026), time limits were a dominant barrier in 15-minute visits; Evidano’s extractive summaries and templated takeaways reduce manual synthesis time, enabling educators to create brief counseling scripts and EMR-friendly after-visit summaries.
Evidano integrates transcription and structured output so programs can prototype short, teachable counseling frameworks and measure adoption.
Problem: Interprofessional gaps with RDs → Feature: Shared data and co-analyzed interviews
According to Hildebrand et al., PLOS One (2026), PCPs worry about being "on the same page" with RDs; Evidano supports shared project spaces and co-coded datasets to surface mismatches between PCP and RD recommendations for targeted interprofessional training.
For teams testing MD–RD co-visit models or tele-dietetics pilots, Evidano helps compare patient and clinician narratives to refine referral criteria and shared language.
Data security and ethics
When analyzing interview transcripts with potentially identifiable information, researchers should follow ethical rules for confidentiality; Evidano supports secure uploads, transcription with PII redaction, and controlled access consistent with research requirements; see Evidano data security.
FAQ: primary care nutrition training
What did the PLOS One study find about PCP confidence in nutrition counseling?
Answer: The PLOS One study found mixed confidence, with many PCPs reporting only modest confidence and learning nutrition outside formal curricula.
According to Hildebrand et al., PLOS One (2026), 41% of participants reported being "somewhat" confident and 34% "fairly" confident addressing nutrition, and many described learning nutrition ad hoc rather than through standardized training.
Why are qualitative interviews useful for redesigning nutrition training?
Answer: Qualitative interviews reveal lived workflows, pain points, and language clinicians use, which quantitative surveys miss.
According to PLOS One (Hildebrand et al., 2026), semi-structured interviews captured variability in assessment, counseling, referrals, and follow-up and produced a conceptual model of four overlapping problems that can directly inform curriculum design and pilots.
Can AI help analyze interview transcripts like those in this study?
Answer: Yes, AI-enabled qualitative tools accelerate coding, theme extraction, and cross-segment frequency analysis while preserving audit trails for reproducibility.
According to the approach described in PLOS One (2026), rigorous qualitative analysis requires validated codebooks and coder agreement; AI tools like Evidano assist by organizing codebooks, visualizing co-occurrence, and producing episode profiles for rapid iteration with human oversight; see Evidano features.
What immediate steps should medical educators take based on these findings?
Answer: Start by defining a minimal, realistic PCP nutrition role and pilot a short framework for 10–15 minute visits.
According to Hildebrand et al., PLOS One (2026), clarifying the PCP role, teaching brief counseling frameworks, and improving RD collaboration are priority actions; educators can use rapid qualitative syntheses to test and refine these interventions.
Conclusion & Next Steps
According to Hildebrand et al., PLOS One (2026), primary care physicians value nutrition but face four core, overlapping barriers: unclear role expectations, inadequate practical training, weak RD collaboration, and system- and societal-level constraints.
Qualitative evidence from 32 in-depth interviews between September 2023 and March 2024 provides concrete, quotable insights to inform curriculum design and system pilots.
AI-enabled qualitative platforms can compress synthesis time, make codebooks reproducible, and support cross-segment comparisons for iterative curriculum development; see Evidano features for relevant capabilities.
