Background. Internet delivered interventions may provide a route to rapid support for behavioural self-management for low back pain (LBP) that could be widely applied within primary care. Although evidence is emerging that more complex technologies (mobile apps linked to digital wristbands) can have some impact on LBP-related disability, there is a need to determine the effectiveness of highly accessible, web-based support for self-management for LBP. Methods and results. We conducted a multi-centre pragmatic randomised controlled trial, testing ‘SupportBack’, an accessible internet intervention developed specifically for primary care. We aimed to determine the effectiveness of the SupportBack interventions in reducing LBP-related physical disability in primary care patients. Participants were randomised to 1 of 3 arms: 1) Usual care + internet intervention + physiotherapy telephone support, 2) Usual care + internet intervention, 3) Usual care alone. Utilising a repeated measures design, the primary outcome for the trial was disability over 12 months using the Roland Morris Disability Questionnaire (RMDQ) at 6 weeks, 3, 6 and 12 months. Results: 826 were randomised, with follow-up rates: 6 weeks = 83%; 3 months = 72%; 6 months = 70%; 12 months = 79%. Analysis is ongoing, comparing each intervention arm versus usual care alone. The key results will be presented at the conference. Conclusion. We believe this to be the largest trial of it's kind internationally. The trial will extend knowledge regarding the effectiveness of highly accessible internet interventions to support self-management and activity in people with LBP consulting in primary care.

Background:. Internet interventions provide an opportunity to encourage patients with LBP to self-manage and remain active, by tailoring advice and providing evidence-based support for increasing physical activity. This paper reports the development of the ‘SupportBack’ internet intervention, designed for use with usual primary care, as the first stage of a feasibility RCT currently underway comparing: usual primary care alone; usual care plus the internet intervention; usual care plus the internet intervention with physiotherapist telephone support. Methods:. The internet intervention delivers a 6-week, tailored programme focused on graded goal setting, self-monitoring, and provision of tailored feedback to encourage physical activity/exercise increases or maintenance. 22 patients with back pain from primary care took part in ‘think aloud’ interviews, to qualitatively explore the intervention, provide feedback on its relevance and quality and identify any extraneous content or omissions. Results:. Valuable feedback and suggested amendments from patients included individually-tailoring the activity programme, using the individual's current pain or activity level. Patients reported that the goal setting module was helpful, and were content with the range of activities offered by ‘SupportBack’. The majority of patients reported they would accept their GP's recommendation and use a credible internet intervention such as this programme to help improve self-management. Conclusions:. The development of the ‘SupportBack’ internet intervention has worked with patients to create an acceptable online tailored resource to supplement primary care management for patients with low back pain. The intervention is currently being trialled to determine feasibility and the most appropriate way to support its delivery

Background. A cornerstone in treating low back pain (LBP) is the provision of information to patients, and the internet is increasingly being used as a source of health information delivery. However, the effect of and satisfaction with online information have been questioned. Purpose. To develop a multi-item instrument to measure an index score of satisfaction with online information for patients with LBP. Methods. The conceptualization of this patient reported outcome is modelled on the assumption of a formative model. The first draft of the questionnaire was developed based on a previous published interview study of 15 patients and evaluated for face validity by seven experts. The second draft of the questionnaire was pilot-tested in 20 patients to optimize content validity. Patients were recruited from a rehabilitation center and from social media. Results. An eight-item questionnaire was developed after assessing content and face validity. The items were related to design, readability, customization, credibility, usability, and coping. A labelled categorical scale was used for response options. Each item is scored from 0–3, where 0 indicates not at all satisfied, 1 indicates little satisfaction, 2 indicates some satisfaction, and 3 indicates very satisfied giving an overall index score between 0 and 24 points. Conclusion. An eight-item questionnaire measuring satisfaction with an index score from 0–24 points has been developed. The OPSI questionnaire is now being tested for construct validity, reproducibility and interpretation on 150 patients with LBP. No conflicts of interest.

Aims

Spinal deformity surgery carries the risk of neurological injury. Neurophysiological monitoring allows early identification of intraoperative cord injury which enables early intervention resulting in a better prognosis. Although multimodal monitoring is the ideal, resource constraints make surgeon-directed intraoperative transcranial motor evoked potential (TcMEP) monitoring a useful compromise. Our experience using surgeon-directed TcMEP is presented in terms of viability, safety, and efficacy.

The aim of this study was to determine whether obesity affects pain, surgical and functional outcomes following lumbar spinal fusion for low back pain (LBP).

A systematic literature review and meta-analysis was made of those studies that compared the outcome of lumbar spinal fusion for LBP in obese and non-obese patients. A total of 17 studies were included in the meta-analysis. There was no difference in the pain and functional outcomes. Lumbar spinal fusion in the obese patient resulted in a statistically significantly greater intra-operative blood loss (weighted mean difference: 54.04 ml; 95% confidence interval (CI) 15.08 to 93.00; n = 112; p = 0.007) more complications (odds ratio: 1.91; 95% CI 1.68 to 2.18; n = 43858; p < 0.001) and longer duration of surgery (25.75 mins; 95% CI 15.61 to 35.90; n = 258; p < 0.001). Obese patients have greater intra-operative blood loss, more complications and longer duration of surgery but pain and functional outcome are similar to non-obese patients. Based on these results, obesity is not a contraindication to lumbar spinal fusion.

We validated the North American Spine Society (NASS) outcome-assessment instrument for the lumbar spine in a computerised touch-screen format and assessed patients’ acceptance, taking into account previous computer experience, age and gender.

Fifty consecutive patients with symptomatic and radiologically-proven degenerative disease of the lumbar spine completed both the hard copy (paper) and the computerised versions of the NASS questionnaire. Statistical analysis showed high agreement between the paper and the touch-screen computer format for both subscales (intraclass correlation coefficient 0.94, 95% confidence interval (0.90 to 0.97)) independent of computer experience, age and gender. In total, 55% of patients stated that the computer format was easier to use and 66% preferred it to the paper version (p < 0.0001 among subjects expressing a preference). Our data indicate that the touch-screen format is comparable to the paper form. It may improve follow-up in clinical practice and research by meeting patients’ preferences and minimising administrative work.

Increasing numbers of posterior lumbar fusions are being performed. The purpose of this study was to identify trends in demographics, mortality and major complications in patients undergoing primary posterior lumbar fusion. We accessed data collected for the Nationwide Inpatient Sample for each year between 1998 and 2008 and analysed trends in the number of lumbar fusions, mean patient age, comorbidity burden, length of hospital stay, discharge status, major peri-operative complications and mortality. An estimated 1 288 496 primary posterior lumbar fusion operations were performed between 1998 and 2008 in the United States. The total number of procedures, mean patient age and comorbidity burden increased over time. Hospital length of stay decreased, although the in-hospital mortality (adjusted and unadjusted for changes in length of hospital stay) remained stable. However, a significant increase was observed in peri-operative septic, pulmonary and cardiac complications. Although in-hospital mortality rates did not change over time in the setting of increases in mean patient age and comorbidity burden, some major peri-operative complications increased. These trends highlight the need for appropriate peri-operative services to optimise outcomes in an increasingly morbid and older population of patients undergoing lumbar fusion.
