RESULTS: The results are presented as four positions that healthcare professionals take, describing their attitudes towards counselling patients about risk disclosure to relatives. The position depends on whether they perceive healthcare or the patient as ultimately responsible for risk information reaching relatives, and whether their focus is on the patient or the at-risk relatives.
