Multi-centre Evaluation of Renal Impairment in Thoracic Surgery

We would like to invite your unit to participate in the MERITS multi-centre project being run in collaboration with SCTS Students

Consultants, trainees, students, data managers


Mortality is very low in thoracic surgery and so using it as a quality discriminator has limitations. Other morbidity measures are needed. Data on acute kidney injury (AKI) is now routinely collected in the NHS.

A pilot audit on AKI post thoracic surgery has been conducted at the Royal Papworth Hospital and presented at the annual meeting of the Society for Cardiothoracic Surgery in March 2018 along with a proposal for a multi-centre audit.

This was discussed and considered highly desirable and as of early April 2018, more than half the GB & I units have expressed an interest to participate.


A pragmatic, high-quality multi-centre audit to evaluate AKI post thoracic surgery.

Useful for benchmarking, quality improvement and safety.
