Objective evaluations of resident performance can be difficult to simulate. A novel competency based surgical OSCE was developed to evaluate surgical skill. The goal of this study was to test the construct validity comparing previously validated Ottawa scores (O-scores) and Orthopaedic in-training evaluation scores (OITE). An OSCE designed to simulate typical general orthopaedic surgical cases was developed to evaluate resident surgical performance. Post-graduate year (PGY) 3–5 trainees have an encounter (interview and physical exam) with a standardized patient and perform a correlating surgery on a cadaver. Examiners evaluate all components of the treatment plan and provide an overall score on the OSCE and also provide an O-score on overall surgical performance. Convergent and divergent validity was assessed comparing OSCE scores to O-scores and OITE scores. SPSS was used for statistical analysis. ANOVA was used to compare PGY averages and Pearson correlation coefficients were calculated to compare OSCE versus O-score and OITE scores. A total of 96 simulated surgical cases were evaluated over a 3 year period for 24 trainees. There was a significant difference in OSCE scores based on year of training. (PGY3 − 6.06/15, PGY4 − 8.16/15 and PGY5 − 11.14/15, p < 0 .001). OSCE and O-scores demonstrated a strong positive correlation of +0.89 while OSCE and OITE scores demonstrated a moderate positive correlation of 0.68. OSCE scores demonstrated strong convergent and moderate divergent correlation. A positive trajectory based on level of training and stronger correlations with established, validated scores supports the construct validity of the novel surgical OSCE.
Despite several hundred RCTs of exercise for persistent non-specific low back pain (NSLBP), the treatment targets of exercise are unclear. In a systematic review we observed 30 direct and indirect treatment targets of exercise described across 23 RCTs for persistent NSLBP. Since not all treatment targets and outcomes can be assessed in all RCTs, it is therefore important to prioritise these treatment targets through consensus from key stakeholders. These consensus workshops aimed to agree treatment targets for the use of exercise interventions in randomised controlled trials (RCTs) in persistent NSLBP using nominal group workshop (NGW) methodology. The first UK workshop included people who had experience of exercise to manage their persistent NSLBP, clinicians who prescribe exercise for persistent NSLBP, and researchers who design exercise interventions tested in RCTs. The second workshop included participants attending an international back and neck pain research workshop. Twelve participants took part in the UK NGW and fifteen took part in the final ranking of the exercise treatment targets. In addition to the original list of 30 treatment targets, a further 26 ideas were generated. After grouping and voting, 18 treatment targets were prioritised. The top five ranked targets of exercise interventions for persistent NSLBP were: pain reduction, improvement in function, reduction of fear of movement, encouragement of normal movement and improvement of mobility. The results of the international NGW will also be presented.Background and Aim of Study
Methods and Results
Complex interventions, such as exercise for LBP, often have many treatment targets. Matching a primary outcome to the target(s) of exercise interventions may provide greater standardized mean differences (SMDs) than using an unmatched primary outcome. We aimed to explore whether the conclusions of exercise trials for LBP might differ with i) improved matching of outcomes to treatment targets and ii) the use of composite outcome measures. We investigated i) matching in five trials (n=1033) that used an unmatched primary outcome but included some of their matched outcomes as secondary outcomes; ii) composite outcomes in four trials (n=864). The composite consisted of standardised averaged matched outcomes. All analyses replicated the primary outcome analysis, applied to the matched or composite outcome in each dataset. When not possible, SMDs were calculated for the primary and matched outcomes. i) Of five trials, three had greater SMDs and increased statistical significance with matched outcomes (pooled effect SMD 0.35 (95% CI 0.16, 0.54), p=0.0003) compared to an unmatched primary outcome (pooled effect SMD 0.13 (95% CI 0.04, 0.23) p=0.007). ii) Of four composite outcomes: two matched trials had greater SMDs and improved statistical precision in the primary outcome than the composite outcome; two unmatched trials had greater SMDs and improved statistical precision in the composite compared to the primary outcome.Background
Methods and Results
Exercise is a complex intervention, and often has more than one treatment target. Results from randomised controlled trials (RCTs) of exercise interventions for chronic low back pain (CLBP) typically show small to moderate effect sizes, but these may differ where outcomes better reflect the targets of interventions. This review aimed to describe what treatment targets, outcome domains and primary outcome measures are used in exercise RCTs, and examined how well the selected outcome domains match the treatment targets used in each RCT. A computer-aided literature search was performed in eight databases, from inception to August 2018. Inclusion criteria: RCTs in CLBP, exercise compared to a non-exercise arm, sample size >60 per arm. Title and abstract review, subsequent full text review, data extraction and risk of bias assessment were independently undertaken by pairs of reviewers. Of 18251 initially identified titles and abstracts, 23 trials were included in the review. 30 treatment targets were extracted, and 6 primary outcome domains identified. A logic model of the treatment targets and outcomes demonstrated diverse relationships. Only 5 RCTs matched their primary outcome domain to the identified treatment targets, 12 used primary outcomes that did not match the reported treatment targets, and 6 were partially matched.Background
Methods and Results
Healthcare practitioners' (HCPs) attitudes and beliefs about MSK pain influence their practice behaviour. The Pain Attitudes and Beliefs Scale (PABS), developed for use in the context of LBP, consists of two subscales (biomedical and biopsychosocial) is the most widely used measure. However, poor performance of the biopsychosocial orientation scale is attributed, in part, to inadequate conceptualisation of the orientation. To develop a new biopsychosocial scale and adapt the PABS to assess HCPs' attitudes and beliefs about common MSK pain.Purpose of the study and background
Purpose
The biopsychosocial (BPS) model is recommended for managing non-specific low back pain (NSLBP) but the best method for teaching the BPS model is unclear. E-learning is a promising alternative to face-to-face methods. This study was a pilot randomised controlled trial (RCT) with embedded interview study to investigate the feasibility of conducting a main RCT and to explore the impact of an BPS for NSLBP e-learning programme on experienced practitioners' attitudes to back pain. Mixed methods evaluated the impact of an evidence-based e-learning programme on participants' attitudes to back pain. A pilot RCT assessed 45 experienced osteopaths' attitudes before and after the intervention, using the Pain Attitudes and Beliefs Scale (PABS) and the Attitudes to Back Pain Scale (ABS). The qualitative study explored 9 participants' views on the e-learning programme and possible impact on their clinical practice. 91% of participants completed the course and the overall satisfaction was very high. Participants' views on the BPS model ranged between not being structural enough, already done and transformative. The e-learning programme was well accepted. It would be feasible to run a main study using the same recruitment procedures, eligibility criteria, randomisation procedure, consent process, data collection and outcome measures.A statement of the purposes of the study and background
A summary of the methods used and the results
Early intervention is advocated to prevent long-term work absence due to musculoskeletal (MSK) pain. The SWAP trial tested whether adding a vocational advice (VA) service to best current care led to fewer days work absence over 4 months. The SWAP trial was a cluster randomised controlled trial in 6 general practices, 3 randomised to best current care (control), 3 randomised to best current care and the VA service (intervention). Patients were ≥18 years, absent from work ≤6 months or struggling at work due to MSK pain. Primary outcome was number of days absent over 4 months. Exploratory subgroup analyses examined whether the effect was larger for patients with spinal pain compared to other MSK pain.Introduction
Methods
Low back pain (LBP) is the most common symptom encountered by osteopaths in the UK and affects a third of the UK population each year. Guidelines recommend using the biopsychosocial (BPS) model for non-specific LBP but it remains unclear what the BPS model actually is and how it applies in osteopathy. The aim of this study was to define the factors included in a BPS approach for non-specific LBP in a manual therapy using a systematic search and scoping review. An online search was performed on seven electronic databases. Guidelines and systematic reviews published after 2004 were included. 10% of the articles randomly selected were analysed by second reviewer to assess consistency of information extraction. Disagreements were discussed between the two reviewers. Mediation from the third author was not required.Background:
Methods:
A wide array of measures has been developed to assess the role of psychological factors in the development and persistence of pain. Yet there is likely to be considerable conceptual overlap between such measures, and consequently a lack of clarity about the importance of psychological factors. To investigate whether conceptual overlap exists within psychological measures used in back pain research.Background
Purpose
The physiotherapy profession has experienced a paradigm shift in recent years where mounting research evidence, indicating better patient outcomes, has led to an increase in popularity of a biopsychosocial model of care. In turn physiotherapists have begun to address psychosocial ‘obstacles’ to recovery, as means of improving outcomes for patients. To date, research has not examined how this change has affected the perceptions of physiotherapists about delivering care. The aim of this study was to explore these perceptions through exploratory interviews with physiotherapists in the UK. A qualitative interview study using a purposive sample of physiotherapists (n=12), nested within a larger study, exploring the attitudes and behaviours of UK general practitioners and physiotherapists about managing patients with low back pain. Interview transcripts were coded by the lead researcher and independently validated by a further team member. Transcripts were coded thematically using the constant comparative method to identify similarities and differences between the data and to determine fit and relevance.Background
Methods
The existence of pulmonary metastases in patients presenting with osteosarcoma is known to indicate a poor prognosis. Lung resection of solitary lesions is now a standard treatment approach, but with limited successful long-term results. We report the progress of a 16-year-old girl with osteosarcoma of the proximal tibia who underwent 11 lung resections for pulmonary metastases over a two-year period, and who has since then been free of disease for seven years.
