Aim The aim of this paper is to reveal the experiences and meaning of confidenti-ality for Australian nurses in the context of whistle blowing. Background Despite the ethical, legal and moral importance of confidentiality within the health-care context, little work has addressed the implications of confi-dentially related to whistle-blowing events. Methods The study used qualitative narrative inquiry. Eighteen Australian nurses, with first-hand experience of whistle blowing, consented to face-to-face semi-structured interviews. Results Four emergent themes relating to confidentiality were identified: (1) confi-dentiality as enforced silence; (2) confidentiality as isolating and marginalizing; (3) confidentiality as creating a rumour mill; and (4) confidentiality in the context of the public's 'right to know'. Conclusions The interpretation and application of confidentiality influences the outcomes of whistle blowing within the context of health-care services. Conversely, confidentially can be a protective mechanism for health-care institutions. Implications for nursing management It is beholden upon nurse manager to care-fully risk manage whistleblowing events. It is important that nurse managers are aware of the consequences of their interpretation and application of confidentiality to whistle-blowing events, and the potentially competing outcomes for individuals and the institution.
