General practitioners (GP) can identify potential cardiac arrest victims. They have the opportunity to inform cardiac patients and their families about the risk of sudden cardiac death and can motivate family members to attend a CPR-course. To study actual counselling practices concerning basic CPR-training a questionnaire was mailed to a representative sample of Belgian GPs (n = 1119). The level of CPR-training of the GPs was fairly good: 67% had received BLS training on a manikin and 63% had already attended a cardiac arrest event. A discrepancy was observed between the positive attitude towards CPR and the counselling of family members to attend a CPR-course (9%). GPs feared to inflict additional stress to the patient (32%) or the family (43%) or did not know where CPR courses were organised (37%). GPs are a primary target group for CPR-training and should learn how to counsel potential bystanders of a cardiac arrest to attend a CPR-course without inflicting additional anxiety on the patient or his family.
