Data were collected in June 2021, through face-to-face, audio-recorded interviews with 36 health professionals selected for convenience and subjected to content analysis, thematic modality. Results: many Primary Care professionals, especially community workers, technicians and nursing assistants, have little knowledge or a distorted view of palliative care, but in their daily lives they assist patients and families.
