Recommendations from the Australasian Faculty of Occupational and Environmental Medicine on low back imaging, opioids, time off work and asbestos exposure. The Australasian Faculty of Occupational & Environmental Medicine (AFOEM) is a Faculty of the Royal Australasian College of Physicians (RACP) that connects and represents Occupational and Environmental Medicine Fellows and trainees in Australia and New Zealand.

Do not order X-rays or other imaging for acute non-specific low back pain, unless there are red flags or other clinical reasons to suspect serious spinal pathology.

Date reviewed: 22 September 2017

As little as two per cent of low back pain cases represent potentially serious conditions requiring surgical or medical intervention. The majority of acute low back pain episodes are benign, self-limiting cases that do not warrant any X-ray or imaging studies. Indeed, unnecessary X-rays and imaging can be harmful due to the potential adverse health effects associated with radiation exposure, incidental findings that trigger more imaging to be performed, and description of asymptomatic, age-related changes in the spine that can result in inappropriate patient anxiety. Moreover, the attribution of symptoms to unrelated incidental findings can then lead to unnecessary surgery.

It is therefore recommended that X-rays and other imaging of the lower back should be performed only if there are red flags such as: a history of significant trauma, cauda equina syndrome, symptoms suggestive of a tumour or infection (fever, weight loss, and a history of cancer), and steroid use. Also, plain radiography is insufficiently sensitive and specific pain associated with these risk factors with the exception of suspected ‘low energy’ fractures e.g. low-height falls in the elderly or osteoporotic. In these cases, plain radiography can be useful to determine whether a fracture is present and inform investigation and treatment of patients at risk of osteoporosis to prevent further fragility fractures.

How this list was made How this list was made

The College worked with the President and EVOLVE Lead Fellow of AFOEM to compile and refine a list of nine recommendations regarding low-value clinical practices in occupational and environmental medicine. This initial list served as the basis for an online survey. Based on survey responses, each of the nine recommendations was assigned a score and ranked accordingly. Based on the ranking of the initial nine, and the review of newly suggested items, these five low-value practices and interventions were chosen.
