SIR – I have recently undergone a serious operation at Airedale Hospital. I am now back home on the way to recovery, mainly due to the doctors, nurses and carers in the intensive care unit, Ward 13 and finally three weeks’ convalescence at Troutbeck Nursing Home, Ilkley.

I cannot praise the patience and devotion of the staff at these institutions highly enough. Thank you all, you are a credit to your profession and the NHS.

Desmond Dawson, Merlin Court, Keighley
