The GP sent a request for a scan to a public hospital but failed to provide any information about the man's symptoms or any assessment findings.
The DHB then did not take action on the scan as the referral was misplaced.
A month later, the man reported new symptoms to his GP, including a "sharp burn" at the back of his throat. The GP then resent the initial referral.
There was no indication of the man's declining health or the urgency of the request, and the referral letter was left on the surgeon's desk until he returned from leave about a month later.
The man then underwent the scan, which showed the cancer had returned. Further investigations showed a blockage in the man's upper abdomen.
He then underwent a laparoscopy, but the surgeon was unable to complete it due to the recurrent cancer. The man never regained consciousness, and later died.
Hill recommended that the GP organise a random audit of 10 referrals and to attend training on communication, and that the DHB review the effectiveness of a number of its measures, including a centralised referral process for tracking referrals.
Hill also recommended that the anaesthetist undergo further training on record-keeping, that the surgeon review his follow-ups after surgery and that the GP, anaesthetist and DHB each apologise to the man's wife for their breaches of the health code.
