This investigation was in response to data suggesting that the rates of mortality at Mid Staffordshire NHS Foundation Trust may be high compared with other trusts, particularly in the area of emergency admissions.

The Healthcare Commission is pioneering systems that use information to spot problems before they become serious. This particular investigation was triggered by an alert system that identified apparently high mortality rates.

We will look at the ability of the trust's information systems to provide an accurate picture of mortality rates and identify potential problems. We will also investigate the quality of care at the trust, in particular the care given to older people, following a number of concerns raised by patients.
