Expanding PrEP access necessitates training that supports healthcare providers' progression along the PrEP implementation cascade, moving from PrEP awareness to prescription. We surveyed 359 USA providers about PrEP training content and format recommendations. We examined the association between cascade location and training recommendations. Most providers were aware of PrEP (100%), willing to prescribe PrEP (97.2%), had discussed PrEP with patients (92.2%), and had prescribed PrEP (79.9%). Latent class regression analysis revealed that cascade location was associated with training recommendations. Although all providers recommended PrEP-specific content (e.g., patient eligibility), providers who were located further along the cascade also recommended more comprehensive content, including sexual history-taking and sexual and gender minority competence training. Providers further along the cascade were also more likely to recommend interactive training formats (e.g., role-playing). These insights from providers furthest along the cascade indicate the importance of including comprehensive content and interactive formats in future PrEP training initiatives.
