          Abstract

          Low back pain is a common and costly condition and for most people is likely to be a recurrent problem throughout their lifetime. The management of patients with low back pain has been positively influenced by the rise in high quality clinical trials and systematic reviews in recent decades, and this body of evidence, synthesized in many clinical practice guidelines, has improved our knowledge about which treatments for low back pain are useful and which are not. For the largest group of patients, those with non-specific low back pain for whom a clear diagnosis cannot be given, the reality is that the treatments we have to offer tend to produce small effects, often only in the short term and none appear to effectively change long-term prognosis. This commentary summarizes the array of treatments currently available, notes the results of recent trials and guidelines and considers alternative approaches that may prove more valuable in achieving better patient outcomes in the future.

          Low back pain: what is the long-term course? A review of studies of general patient populations.

          It is often claimed that up to 90% of low back pain (LBP) episodes resolve spontaneously within 1 month. However, the literature in this area is confusing due to considerable variations regarding the exact definitions of LBP as well as recovery. Therefore, the claim--attractive as it might be to some--may not reflect reality. In order to investigate the long-term course of incident and prevalent cases of LBP, a systematic and critical literature review was undertaken. A comprehensive search of the topic was carried out utilizing both Medline and EMBASE databases. The Cochrane Library and the Danish Article Base were also screened. Journal articles following the course of LBP without any known intervention were included, regardless of study type. However, the population had to be representative of the general patient population and a follow-up of at least 12 months was a requirement. Data were extracted independently by two reviewers using a standard check list. The included articles were also independently assessed for quality by the same two reviewers before they were studied in relation to the course of LBP using various definitions of recovery. Thirty-six articles were included. The results of the review showed that the reported proportion of patients who still experienced pain after 12 months was 62% on average (range 42-75%), the percentage of patients sick-listed 6 months after inclusion into the study was 16% (range 3-40%), the percentage who experienced relapses of pain was 60% (range 44-78%), and the percentage who had relapses of work absence was 33% (range 26-37%). The mean reported prevalence of LBP in cases with previous episodes was 56% (range 14-93%), which compared with 22% (range 7-39%) for those without a prior history of LBP. The risk of LBP was consistently about twice as high for those with a history of LBP. The results of the review show that, despite the methodological variations and the lack of comparable definitions, the overall picture is that LBP does not resolve itself when ignored. Future research should include subgroup analyses and strive for a consensus regarding the precise definitions of LBP.

            Group cognitive behavioural treatment for low-back pain in primary care: a randomised controlled trial and cost-effectiveness analysis.

            Low-back pain is a common and costly problem. We estimated the effectiveness of a group cognitive behavioural intervention in addition to best practice advice in people with low-back pain in primary care. In this pragmatic, multicentre, randomised controlled trial with parallel cost-effectiveness analysis undertaken in England, 701 adults with troublesome subacute or chronic low-back pain were recruited from 56 general practices and received an active management advisory consultation. Participants were randomly assigned by computer-generated block randomisation to receive an additional assessment and up to six sessions of a group cognitive behavioural intervention (n=468) or no further intervention (control; n=233). Primary outcomes were the change from baseline in Roland Morris disability questionnaire and modified Von Korff scores at 12 months. Assessment of outcomes was blinded and followed the intention-to-treat principle, including all randomised participants who provided follow-up data. This study is registered, number ISRCTN54717854. 399 (85%) participants in the cognitive behavioural intervention group and 199 (85%) participants in the control group were included in the primary analysis at 12 months. The most frequent reason for participant withdrawal was unwillingness to complete questionnaires. At 12 months, mean change from baseline in the Roland Morris questionnaire score was 1.1 points (95% CI 0.39-1.72) in the control group and 2.4 points (1.89-2.84) in the cognitive behavioural intervention group (difference between groups 1.3 points, 0.56-2.06; p=0.0008). The modified Von Korff disability score changed by 5.4% (1.99-8.90) and 13.8% (11.39-16.28), respectively (difference between groups 8.4%, 4.47-12.32; p<0.0001). The modified Von Korff pain score changed by 6.4% (3.14-9.66) and 13.4% (10.77-15.96), respectively (difference between groups 7.0%, 3.12-10.81; p<0.0001). The additional quality-adjusted life-year (QALY) gained from cognitive behavioural intervention was 0.099; the incremental cost per QALY was 1786 pound sterling, and the probability of cost-effectiveness was greater than 90% at a threshold of 3000 pound sterling per QALY. There were no serious adverse events attributable to either treatment. Over 1 year, the cognitive behavioural intervention had a sustained effect on troublesome subacute and chronic low-back pain at a low cost to the health-care provider.

              Outcome of low back pain in general practice: a prospective study.

              To investigate the claim that 90% of episodes of low back pain that present to general practice have resolved within one month. Prospective study of all adults consulting in general practice because of low back pain over 12 months with follow up at 1 week, 3 months, and 12 months after consultation. Two general practices in south Manchester. 490 subjects (203 men, 287 women) aged 18-75 years. Proportion of patients who have ceased to consult with low back pain after 3 months; proportion of patients who are free of pain and back related disability at 3 and 12 months. Annual cumulative consultation rate among adults in the practices was 6.4%. Of the 463 patients who consulted with a new episode of low back pain, 275 (59%) had only a single consultation, and 150 (32%) had repeat consultations confined to the 3 months after initial consultation. However, of those interviewed at 3 and 12 months follow up, only 39/188 (21%) and 42/170 (25%) respectively had completely recovered in terms of pain and disability. The results are consistent with the interpretation that 90% of patients with low back pain in primary care will have stopped consulting with symptoms within three months. However most will still be experiencing low back pain and related disability one year after consultation.
