WHY BACK PAIN TRIAGE

Abstract

Three developments in the last 10 to 15 years have made it necessary to review how we ensure rapid access to treatment of patients with disabling low back pain.

Firstly, there would appear to be an increase in the numbers of patients seeking medical help for low back pain, whether due to increased patient expectation, or better reporting, or a true increase associated with the increasing sedentary nature of life, is uncertain. Secondly, there is the realisation that amongst the factors that encourage acute back pain to become chronic is being off work, and the sooner a diagnosis and treatment is started the more likely that chronicity will be prevented, so a long waiting time to be seen in a clinic is productive of disability. Thirdly, reorganisation of consultant services has created the spinal surgeon, who in return for being allowed to practice spinal surgery almost exclusively undertakes the load of patients referred with back pain, amongst whom lurk those with a surgically remediable problem. The effect has been that although waiting times for general orthopaedic patients have dropped, as general orthopaedic, or other specialist orthopaedic surgeons no longer see spinal cases, the specialist spinal surgeon is overwhelmed by a large group of patients with back pain for whom there is not a surgical solution. Unfortunately, there is a shortage of spinal surgeons, which is likely in the UK at any rate to get worse. Being overwhelmed with non-surgical back pain interferes with their ability to deal with surgical problems. It also does create a recruitment problem, as back pain is not seen as a rewarding or satisfying problem to treat.

Triage is a method of screening patients into groups at an early stage, identifying those who might benefit from surgery, and fast tracking them, identifying those who will benefit from other management and tracking them accordingly. Pioneered in general orthopaedics by Robin Ling in Exeter, it has been developed in the hospital setting somewhat randomly, by dedicated enthusiasts, many of whom will be speaking today. The purpose of this meeting today is to hear about the various systems, their funding and organisation and location, the triage staff used, the investigations used in primary triage and the effect on hospital specialist waiting times, the safety and patient satisfaction. Is a multiplicity of systems best, is one better than another, why have some units achieved no waiting times for MRI, and others six months etc?

In 1994, the Clinical Standards Advisory Group produced two books, An epidemiological Review, largely the work of Gordon Waddell, and a second book on Back Pain, chaired by Professor Michael Rosen with, I suspect, considerable input from Professor Waddell and others. Many of us met them when they toured the country collecting facts about the treatment and management of back pain. It discusses back pain triage, and suggests that it can be done within the average GP Consultation time of 9 minutes. It deals with simple back ache, “red flags”, (we now have “yellow flags” denoting the psycho-social factors) nerve root pain, cauda equina and inflammatory disorders. It is to be noted that chronic back pain, is not alluded to in the diagnostic triage, but it is stated that 90% of simple back ache recovers in six weeks. Their management guidelines emphasise the value of physical therapy (manipulation and active exercises), but it will be noted that they are addressed to a group of patients, 90% of whom will recover in six weeks. Sadly, therefore, the effect of this very sensible document, in ignoring in the triage system the chronic patient, has in many cases directed therapy in general practice towards open access for patients who in any event will improve spontaneously.

We must therefore address where triage should be, hospital, or GP level. Certainly a GP gatekeeper will remove the acute back pains that are going to get better soon anyway from attending hospital and in certain units, a separate fast track is provided for acute radicular problems (Acute Sciatic Clinics).

Any successful triage system involving chronic back pain must be associated with treatment possibilities, and I shall briefly discuss these, although the main thrust of the afternoon will be the triage organisation itself.

The session is designed to allow considerable audience participation, as it is hoped that information, comments and criticisms from the audience will allow us to subsequently produce a booklet, hopefully with support from our Professional Societies, describing what we feel is Best Practice in Back Pain Triage, which we hope, after appropriate circulation, will encourage Trusts and Community Health Groups to develop such units and ensure that back pain patients get a better deal.
