“…Ethical and professional guidelines, [1][2][3] credentialing organizations, 4 patient safety organizations, 5 and experts on medical errors advocate disclosure of medical errors to patients and families, [6][7][8][9][10][11][12][13][14][15][16][17][18][19] but there is little empirical evidence to guide practitioners. We found empirical support for concluding that disclosure often does not occur, 22,28,30,32,36 that patients and the public favor disclosure, 23,24,29,32,34 and that physicians support disclosure, 23,28,32 but we found no empirical results to guide practitioners with respect to the practical questions of who, what, when, and how to disclose.…”
