In the mid to late 2000s, while Executive Director of the Association of Salaried Medical Specialists, I used the term
‘data cleansing’ to describe a policy under the then Labour-led government when Pete Hodgson was health minister.
When general practitioners considered that their patients required further investigations by hospital specialists, they
would refer them to the relevant district health boards (DHB).
These further investigations are called ‘first specialist assessments’ (FSA’s). Those patients who could be assessed
were then placed on a waitlist for their treatment such as surgery. The prescribed maximum waiting time was four months.
The issue was the growing number of patients requiring further investigation who were not placed on the waitlist.
Instead, due to a mix of hospital underfunding and understaffing, they were referred back to their GPs from whence they
had come.
Inevitably patients were placed under stress as a result of this continued uncertainty about their health and when their
necessary further investigations would be undertaken.
Unsurprisingly, their worried GPs were also stressed. Few things are more worrying for a GP than knowing that their
patients are fretting and at increased risk of harm or death because further investigations into their conditions have
been denied.Cleansing data
Unfortunately there was a conscious decision not to report (and most likely record) data on the number of patients who
were referred but denied access to FSAs. Data reporting was confined to just those patients who accessed them.
This is what I called data cleansing. The official data looked good; the real situation for many was dire; for some
fatally so.
Strictly speaking this was not technically accurate. In the IT world, data cleansing is the process of finding and
removing errors, inconsistencies, duplications, and missing entries from data to increase data consistency and quality.
However, levering off the expression ‘ethnic cleansing’, I adapted the term accordingly. The bad news is that this
practice has gotten worse as the crisis in Aotearoa New Zealand’s health system further deteriorates.
The relatively good news is that “groundbreaking” academic research has made this transparent. In the words of the
researchers it reveals a “national scandal”.Revealing a national health scandal
Undertaken by the University of Otago, in conjunction with General Practice New Zealand (GPNZ), the research was
released on 4 June: Impact of unmet patient need on general practices.
It is positive to see this sort of collaboration between university academia (Professor Robin Gauld, Dr Jerram Bateman
and Dr Nick Bowden) and a major general practice body such as GPNZ, which represents the primary care organisations.
They are to be congratulated for doing what the Ministry of Health and Health New Zealand (Te Whatu Ora) have failed to
take responsibility for; the duplicity of data cleansing.
GPNZ released its own statement on the research two days later: Research reveals hidden pressures on general practices.
The same day Radio New Zealand’s health correspondent Rowan Quinn also covered the findings: Over 85,000 GP referred patients annually prevented from seeing hospital specialists for necessary investigations.Drilling down to the study’s findings
The study was based on both quantitative and qualitative analysis leading it to conclude that unmet health needs are
jeopardising patient healthcare and straining general practices.
It drilled down further to conclude that:access to hospital specialist services was declining;there were equity and regional disparities;patients were experiencing delayed treatments, poorer health outcomes, and exacerbating health inequities;already stretched GPs were being overburdened; andthere were negative financial implications for both patients and general practices.
In the words of Porirua GP and Chair of GPNZ, Dr Bryan Betty:
The study shows more and more New Zealanders are unable to access specialist care in a timely way, leaving GPs to manage
these complex cases without extra resources. This not only affects patients, who suffer from delayed treatments, but
also puts immense pressure on GPs, making it harder for them to provide quality care.
Some of these at least 85,000 referred patients a year are being turned away from seeing a hospital specialist; worse
still some of them are dying as a result.
In the words of Professor Gauld it was “appallingly bad” for patients who could be in pain or disabled because their
condition could not be treated. “We have thousands and thousands of people around the country not living life to their
full potential.”Time to end this health scandal
Retired Christchurch general surgeon Phil Bagshaw has been campaigning for years for a full investigation into the level
of unmet health need in New Zealand but has been batted off by successive governments.
This research is not the full investigation he and his colleagues wanted. But it is an important step in the right
direction and provides some badly needed transparency. It has indeed exposed a national health scandal. This work needs
to continue.
More importantly, the political and bureaucratic leadership of our health system need to focus as a matter of exigency
on addressing the causes of this scandal beginning with across-the-board workforce shortages.
