The Independent Medicines and Medical Devices Safety Review (IMMDSR) has recently published evidence submitted to the Review, following its oral hearings. ISCAS provided written evidence to emphasise the important role played by independent adjudication in affording private patients an escalation pathway for unresolved complaints about subscribing organisations. Our evidence included an overview of what is covered by the ISCAS Code, background on the regulatory context including with reference to practising privileges, the key elements of the Information Sharing Agreement (ISA) with the Care Quality Commission (CQC) and how lessons learned our incorporated into ISCAS training events. The issue regarding the lack of access to the Parliamentary and Health Services Ombudsman (PHSO) for private patients treated in the majority of NHS Private Patient Units (PPUs) was also outlined.
