About NOGCA
The National Oesophago-Gastric Cancer Audit (NOGCA) measures the quality and outcomes of care for people with oesophageal or gastric cancer in NHS Trusts in England and Health Boards in Wales, with the goal to improve the quality of care provided.
The Audit is commissioned by the Healthcare Quality Improvement Partnership (HQIP), funded by NHS England and the Welsh Government.
The Audit involves a wide range of professionals and organisations that collaborate to ensure its effectiveness. The core group is the NOGCA Project Team, which works in close consultation with its own Clinical Reference Group and a Patient & Public Involvement Forum to integrate expert and patient perspectives.
Beyond these groups, the Audit is a partnership between several organisations; the Healthcare Quality Improvement Partnership (HQIP) commissions the Audit, funding is provided by NHS England and the Welsh Government. The National Cancer Audit Collaborating Centre (NATCAN), which is part of the Royal College of Surgeons of England’s Clinical Effectiveness Unit, is responsible for delivering the Audit and managing the data.
