A professional world without borders would allow for more appropriate collaboration between the Coroner's office and the healthcare sector in their endeavours to improve patient safety. In Victoria (Australia), the Clinical Liaison Service draws on the distinct experiences and expertise of medical, nursing and research personnel to evaluate clinical evidence for the investigation of healthcare deaths reported to the State Coroner's Office. This approach allows for greater intersectoral collaboration between the Coroner's office and healthcare sector than a traditional English-style coronial system that relies on the expertise of coroners, forensic pathologists and police officers to investigate unexpected deaths. Encouraging collaboration between these two sectors may have averted or at least mitigated the atrocities caused by Harold Shipman or the events at Bristol's Royal Infirmary. This paper describes the work processes employed by the Clinical Liaison Service (CLS) to investigate healthcare deaths in a coronial setting. To describe how this work has fostered the advancement of patient care.
