The Guardian reports that twin children have been killed by a serious untoward incident - it would appear, by a clinical error in rate of medication dosage - at Mid-Staffordshire NHS Foundation Trust.

Oh no. Not again.

A culture of learning from error - and patient safety - seems to be as far away as ever.

UPDATE: A Press Association report today suggests that the babies may have died from prematurity.

The Guardian also carries a report from the police that states, "preliminary results suggest that the twins died because of their prematurity rather than as a direct result of any medical treatment."".
