Hospitals in England are working to get patients home for Christmas and recover from disruption caused by five days of doctor strikes.
Resident doctors - previously called junior doctors - are returning to work after a walkout over ongoing pay disputes.
Thousands of elective and outpatient appointments were cancelled as senior doctors were redeployed to cover emergency and urgent care. The NHS Confederation, which represents hospital trusts, says the full impact on patients is still being assessed.
The strike went ahead amid surging flu cases, and despite last-minute talks between the British Medical Association (BMA) and the government.
