Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, what research his Department has conducted or commissioned on the length of time taken by doctors to adjust to day shifts after night shifts; and whether his Department has formed a policy on the minimum and maximum number of consecutive night shifts doctors should work.

The Department has not directly commissioned such research. A number of previously published papers and studies on shift working informed negotiations with the British Medical Association (BMA). The limits on working hours in the new contract were agreed in discussions with the BMA and include a maximum of four consecutive night shifts and a minimum of 48 hours rest after three or four consecutive night shifts. We have also agreed to review the operation of the contract with the BMA to identify whether we can move further on night working.
