Informing patients about group adverse events.

Group adverse events are those affecting a multitude of individuals rather than a single patient. Although uncommon a group adverse mishap has the potential to cause widespread patient harm and wreak havoc at the implicated institution. The ensuing investigation and surrounding publicity can impact adversely on public confidence. The quantum of error varies enormously. On the one hand the error may be small and risk of harm negligible. While on the other hand the risk of injury may be substantial. When an adverse event affecting a group of patients takes place the issue of disclosure is of central importance. It is important to appreciate what the term means. Disclosure is the forthright and empathetic discussion with a patient or group of patients about the clinical facts surrounding a harmful event or an event that could cause harm in the future. In general terms there is an ethical and legal obligation to inform patients about any mishap or potential mishap that has been sustained during their care.
