The X-ray was done and a few hours later the ICU night team handed over duties to the ICU day team.
Neither teams reviewed the X-ray. That afternoon, the man died. The man's X-rays were reviewed for the first time at a multi-disciplinary radiology meeting the following day.
A large tension pneumothorax - which could affect normal breathing - was visible on his chest X-ray which had not previously been detected by any member of staff.
Mr Hill determined that the failure to review the X-ray was caused by a lack of clarity from Southern District Health Board regarding who was ultimately responsible for ordering and reviewing postoperative X-ray.
He said that in this case, individual clinicians "accepted a presumptive diagnosis" without having regard to the "bigger picture of the patient's presentation".
"All these issues were compounded by poor communication...which ultimately affected the quality and continuity of services provided to the man," Mr Hill said in his report.
Mr Hill recommended that the Southern District Health Board apologise to the man's family, review its processes regarding handover of care and responsibility of reviewing X-rays.
