"Nurses did not always wash their hands between patients. The cleaning was often dilatory. No one appeared to supervise the cleaners and none was done at weekends." Carole Heatly, chief executive at Kingston Hospital NHS Trust, said: "We can only apologise for Mr Baker's experience. As he has identified in his article, our staff are superb, as is our clinical care. However, we recognise that there is still more for us to do to improve cleanliness on site, which is a hugely important area for us."
