[Reflections on ethnography in the emergency department].

: Ethnography is the principal research method in Anthropology. With a broad scope, it allows using different data collection techniques and incorporates elements observed and obtained in the field into the analysis. In Public Health, it can contribute to understanding the health/disease process and health professionals' and patients' values and attitudes in different healthcare settings. The aim of this article is to present and discuss the ethnographic method based on an empirical study of physicians' hospital work in the face of the limits between life and death. Data collection involved nine months of participant observation and interviews with 43 physicians (25 men and 18 women), 28 to 69 years of age, treating critical patients in different departments of a metropolitan emergency hospital. The various social and cultural aspects experienced by the researcher and obtained from the interlocutors in the field provide a dense description of this hospital ethnography.
