County Durham and Darlington NHS Foundation Trust

County Durham and Darlington NHS Foundation Trust is an NHS Foundation Trust based in North East England. It runs two acute hospitals in University Hospital of North Durham and Darlington Memorial Hospital as well as further non-acute centres at Shotley Bridge Hospital, Sedgefield Community Hospital, Richardson Community Hospital, Weardale Community Hospital, Bishop Auckland Hospital and Chester-le-Street Hospital. The Chief Executive is Sue Jacques. The most recent review of the Trust by the Care Quality Commission in 2019 provided an "Overall: Good" rating.

In 2015 the trust established a subsidiary company, Synchronicity Care Ltd. The intention was to achieve VAT benefits, as well as pay bill savings, by recruiting new staff on less expensive non-NHS contracts. VAT benefits arise because NHS trusts can only claim VAT back on a small subset of goods and services they buy. The Value Added Tax Act 1994 provides a mechanism through which NHS trusts can qualify for refunds on contracted out services.

In 2018 it made a 14-year managed service agreement with Royal Philips Electronics to run imaging and cardiology services across four sites.
