Future for Rural Hospitals?

by Kevin Hague

The West Coast is the most sparsely populated region in New Zealand. Just 31,000 people live in the narrow strip of land between the mountains and the sea, while the distance from Karamea in the North to Haast in the South is about the same as that from Auckland to Wellington. That’s a popoulation density just 10% of the New Zealand average, distributed over large distances. It can be a challenging environment to provide services in, particularly when those services are specialised.

Hollowing Out Rural NZ

Rural areas in general have sustained what I call “hollowing out”, where a vicious circle of service losses and population reductions has seen a dramatic shift in the viability of rural life. While we maybe associate this mostly with the wave of closures of banks and Post Offices etc in the 1980s, the trend has continued with school ‘rationalisations’ and so forth. One of the ideas was that technology would help overcome the tyranny of distance. Maybe. But then consider the Government’s roll-out of “super fast broadband”. In fact that will see the digital divide between town and country widen further still, as Rural Women and Federated Farmers have been saying, making rural life harder still (of course there are compensations!)

Rural Heath Services

In health services, rural DHBs have been focusing strongly on good public health services, intended to keep people well. No surprises there. That’s Green Party policy too. Then the focus is on primary care – those community-based services that people are able to access directly when they first seek treatment for a problem. There’s a big problem in recruiting and retaining doctors and nurses to fill these roles: traditional small business models of general practice are often unviable, access to support is thin, the skillset required for rural practice is broad and the after hours requirements can be arduous. Nonetheless the work suits some people, attention is being focused on the area, technology is helping, and it looks to me as if this is starting to turn around.

More at risk are specialist services, typically hospital-based, for rural areas. This last week saw yet another report published concerning the future of these services on the West Coast, which, as the most rural DHB, is at the sharp end of the difficulties faced in rural and provincial New Zealand. A quick glance at the report and I have a strong sense of deja vu – it closely resembles proposals I wrote around 5 years. It’s not surprising really because the issues haven’t changed.

At their heart these are issues around the employment of specialist doctors and surgeons. Not so long ago rural hospitals were staffed by generalists, who were able to work across a broad range of areas of work (the general surgeon would whip out your appendix, set your broken leg or deliver a baby by Caesarian section etc). Therefore rural hospitals didn’t need many of them.  In the intervening years there has been a very rapid trend of specialisation (and sub-specialisation) in these professions. People work now to a much greater degree of skill and depth, but in a much narrower “scope of practice”. That means that a hospital needs more departments to adequately cover the range of health issues that may present. Each of these departments really needs 3 or 4 specialists, to ensure 24/7 acute (urgent) care, and provide cover for training, leave etc.

This is possible for progressively fewer and fewer hospitals. A further problem is that the cost of providing this capacity may well exceed (and over time will be more likely to) the hospital’s income, which is essentially proportional to the population served and services provided. Rural specialist care costs more.

The Two Options

In fact New Zealand stands at a crossroads on rural specialist care. Under current trends, rural (and then provincial) hospitals will be untenable, and replaced by super primary care centres with some beds for observation by GPs and nurse practitioners, and the ability to stabilise patients before shipping them out to city hospitals. This will be an efficient use of the specialists, and patients will have considerable expertise and backup available to them when they arrive in the city hospitals. However this option comes at some costs. For a start the travel by patients is effectively a significant cost-shifting to them, and may be a considerable and sometimes impassable barrier for them. But sometimes they won’t even make it. Sometimes the West Coast is effectively isolated from everywhere else, with aircraft unable to fly and passes blocked. And sometimes a patient’s condition won’t tolerate the further delay of transport – emergency Caesarian, cranial bleeding, torsion of the testes (have never looked into the detail of that one, and don’t think I want to!) If hospital services are further away, some people will die because of the delay in treatment. Probably not many, but some.

But if we don’t want this future of centralisation of specialist services to the main centres only, then we need to do some things very differently. We need to restart training generalists, who will be able to provide the 24/7 acute cover necessary in rural hospitals, and to do so in sufficient numbers. There are some positive signs with the great work done by the doctors from Dunstan Hospital, which has resulted in rural hospital medicine being recognised as a separate vocation, with its own training path and broad scope. The surgical equivalent will also be needed. We will also need different employment arrangements for specialists, to facilitate the provision of their expertise in multiple centres (if we are to maintain local access to specialist services in rural areas and to make the best use possible of the resources we have, then both specialists and patients will sometimes have to travel, for example to take advantage of operating theatres with spare capacity). It won’t make sense for the West Coast to have its own specialist departments, but rather to receive visiting services from the “South Island Regional Surgical Service”. Finally we also need Government to pay for the infrastructure to support this model, including hospital buildings and facilities that are fit for purpose. And as a microcosm of the the problem that rural areas need to be funded for capacity, rather than volume, these rural hospitals won’t stack up on a volume-based affordability test. They will cost more, and the more rural they are, the more they will exceed conventional affordability.

So that’s the choice in stark terms: one alternative will cost more in dollars, while the other will cost more in lives. As you might imagine, people on the West Coast get a bit nervous about earthquake risk. Much of the Grey Base Hospital doesn’t come anywhere near compliance with the new Building Code and, as a result, no changes at all can be made to the buildings without incurring a massive cost to bring the existing building up to compliance. At which point the DHB would have a compliant building, but one which has a layout and functionality designed to meet the way of providing hospital care in vogue some decades ago.

The DHB has submitted plans for a new hospital, designed to suit the needs of what is realistic for a rural hospital staffed by generalists and serviced by visiting specialists. These have been batted back by Ministers as “too expensive”. The Minister will have to choose one or the other. The clock is ticking. And rural and provincial New Zealand will be watching to see what our future holds.
