Effective communication is crucial in Primary Health Care (PHC) but often lacks structured training in in-service programs. This report describes the implementation of video analysis using the Calgary-Cambridge Observation Guide (CCOG) within a specialization course for a large-scale national primary care provision program in Brazil.We analyzed 20 video-recorded consultations from 10 family medicine trainees. The 28-item version of the CCOG was used as a formative assessment tool. Following established feedback protocols, sessions prioritized the learner's agenda and anchored comments to specific guide items , avoiding clinical judgment to focus strictly on communication skills. The process aimed to identify specific behavioral gaps in a safe learning environmentThis experience is innovative in its systematic application of the CCOG within a massive public health training program. It differentiates itself by using quantitative video data to deconstruct the common assumption among professionals that "politeness" is equivalent to "technical communication competence."Data revealed a distinct pattern: while 100% of participants excelled in politeness and initial rapport (Items 1-3), significant technical gaps were identified. Notably, 85% failed to use internal summaries (Item 17), 75% did not negotiate the agenda (Item 5), and 55% used unclear language (Item 10). Furthermore, 40% missed exploring the patient's perspective (Items 13-14). Future training must shift focus from general humanization to specific structuring techniquesThe results suggest that physicians in this context possess strong relational skills but lack structural techniques. The high failure rate in "agenda setting" and "summarizing" indicates reactive rather than proactive consultation management. Video evidence was pivotal in highlighting these deficits, including non-verbal interferences like computer use, observed in 25% of cases.Using the CCOG on video recordings transformed subjective perceptions into actionable educational data. It proved effective in diagnosing specific skill gaps, demonstrating that empathy must be paired with structured communication techniques to improve quality of care.
