The potential effects on clients, relatives and staff members when things go wrong, can be devastating. Duty of candour, implemented under the Health and Social Care Act 2008 (Regulated Activities) Regulations 2014: Regulation 20, outlines the principles that staff members should use when communicating with clients, relatives and/or carers following an incident where harm has occurred, or where there is a risk or possibility that the incident could lead to or result in harm. It underpins a culture of openness, honesty and transparency, and is a duty on the organisation as a whole, as well as individual staff members working within the organisation.
