This case concerns the care provided by Te Whatu Ora to a woman who requires five-yearly surveillance colonoscopies.
The results of a surveillance colonoscopy noted that four polyps were removed, and two biopsies were carried out, all of which were reported as normal. It was recommended that five-yearly surveillance colonoscopies continue.
Despite these results, the woman received a telephone call from the colonoscopy clinic two days later advising that the reporting specialist had referred her for a further urgent colonoscopy, which was scheduled accordingly.
Prior to the urgent colonoscopy appointment, the woman left voicemails for the referring specialist to confirm the reasons for the further procedure, to which she received no response.
At the colonoscopy appointment, the woman asked the registered nurse undertaking the consenting process why the colonoscopy was required. The nurse provided no reasoning for the colonoscopy and did not record the query in the patient’s clinical records or follow up with the specialist who was to undertake the colonoscopy.
During the procedure, the specialist undertaking the colonoscopy (who was not the referring specialist) noted that the findings on the referral form were not consistent with what was being seen in the colonoscopy in real time.
The specialist performing the procedure contacted the referring specialist and it was picked up that there had been an accidental mix-up of National Health Index (NHI) numbers, and the incorrect patient was having the urgent colonoscopy.
After the woman’s sedation had worn off, the specialist informed her that there had been a mix-up with NHI numbers, resulting in her having an unnecessary colonoscopy.
Post-colonoscopy the woman received a verbal apology from the referring specialist. She also received a letter from the Clinical Quality and Risk Manager, who apologised and advised the woman that an adverse event review (AER) would be undertaken to determine the cause of the NHI number mix-up. The AER found the following:
1. The referring specialist made a documentation error when using the Gastro Admin email and accidently attached the incorrect NHI number to the email.
2. The report results stating that all tests were normal were available the next day, but no one looked at or questioned the results with the referring specialist.
3. The telephone call from the woman was a missed opportunity for the administrative staff to identify the error of urgent booking, and it is unclear why this did not occur.
4. The consent process was performed by a registered nurse, and neither the nurse nor the specialist who performed the procedure looked at previous reports when the woman questioned why she needed the procedure.
The Deputy Health and Disability Commissioner, Vanessa Caldwell, considered that a serious incident had occurred, which had resulted in a patient receiving a colonoscopy she did not require. This was identified in the AER completed by Te Whatu Ora. In addition, this type of incident is captured in the Te Tāhū Hauora|Health Quality and Safety Commission’s ‘always report and review list’. Two previous HDC cases found a breach of the Code of Health and Disability Services Consumers’ Rights (the Code) in similar circumstances.
The Deputy Commissioner considered that Te Whatu Ora failed to provide services to the woman with reasonable care and skill. As such, she found Te Whatu Ora in breach of Right 4(1) of the Code.
