Prognostic indicators for poor outcomes in low back pain patients consulted in primary care.

ABSTRACT: BACKGROUND:Non-specific low back pain (NSLBP) is the most prevalent musculoskeletal condition in western countries and is associated with persistent disability and high consumption of health care resources. NSLBP patients first seek primary health care services but the outcomes are often uncertain. This study aimed to examine the clinical course of the outcomes and to identify prognostic indicators for poor outcomes in NSLBP patients who consulted primary care. METHODS:A prospective cohort study of 115 patients seeking treatment for NSLBP in primary care was conducted. Participants were consecutively recruited by their General Practitioners (GPs) and then assessed at baseline and 2 and 6 months later. Baseline assessment included socio-demographic and clinical data, psychosocial factors, pain, disability, and health related quality of life (HRQoL). Pain, disability, HRQoL and global perception of change were also assessed at 2 and 6-months' follow-up. In addition, information regarding the GP' practice was collected. Poor outcomes were determined according to the cut-off point used to define a persistent disabling condition and the minimal important change established for disability, pain and for global perception of change. The relationship between variables on baseline and poor outcomes was modulated through binary logistic regression analysis. The significance of associations was evaluated at ? 0.05 p-value with 95% confidence intervals (CI) and adjusted odds ratios (AOR). RESULTS:110 (94.8%) and 104 (89.7%) participants completed the follow-up assessment at 2 and 6 months, respectively. The mean age (±SD) was 48.06 ± 11.41, with 53.9%, (N = 62) reporting an acute presentation of NSLBP. Six months after GP consultation, 53.8% (N = 56) of the participants reported a persistent disabling condition. An "LBP episode of less than 12 weeks" [AOR: 0.26; 95% CI (0.10, 0.65); AOR: 0.34; 95% CI (0.14, 0.81); AOR: 0.21; 95% CI (0.09, 0.53)],"maladaptive psychosocial factors" [AOR: 2.06; 95% CI (1.40, 3.04); AOR: 1.82; 95% CI (1.27, 2.59); AOR: 1.72; 95% CI (1.20, 2.47)] were significantly associated with poor outcomes on disability, pain and global perception of change, respectively. Besides these factors, being employed reduces the chances of poor outcomes on disability [AOR 0.31; 95% CI (0.11, 0.92)]. CONCLUSIONS:A large proportion of LBP patients seeking primary health care reported poor outcomes 6 months after GP consultation. Patients who report chronic LBP, maladaptive psychosocial factors and are unemployed have a significant increase in the risk of poor outcome. These findings suggest the need of implementing effective models of care able to provide early screening and appropriate treatment to those at greatest risk of a poor outcome.

Project description:Low-back related leg pain with or without nerve root involvement is associated with a poor prognosis compared to low back pain (LBP) alone. Compared to the literature investigating prognostic indicators of outcome for LBP, there is limited evidence on prognostic factors for low back-related leg pain including the group with nerve root pain. This 1 year prospective consultation-based observational cohort study will describe the clinical, imaging, demographic characteristics and health economic outcomes for the whole cohort, will investigate differences and identify prognostic indicators of outcome (i.e. change in disability at 12 months), for the whole cohort and, separately, for those classified with and without nerve root pain. In addition, nested qualitative studies will provide insights on the clinical consultation and the impact of diagnosis and treatment on patients' symptom management and illness trajectory.Adults aged 18 years and over consulting their General Practitioner (GP) with LBP and radiating leg pain of any duration at (n = 500) GP practices in North Staffordshire and Stoke-on-Trent, UK will be invited to participate. All participants will receive a standardised assessment at the clinic by a study physiotherapist and will be classified according to the clinically determined presence or absence of nerve root pain/involvement. All will undergo a lumbar spine MRI scan. All participants will be managed according to their clinical need. The study outcomes will be measured at 4 and 12 months using postal self-complete questionnaires. Data will also be collected each month using brief postal questionnaires to enable detailed description of the course of low back and leg pain over time. Clinical observations and patient interviews will be used for the qualitative aspects of the study.This prospective clinical observational cohort will combine self-reported data, comprehensive clinical and MRI assessment, together with qualitative enquiries, to describe the course, health care usage, patients' experiences and prognostic indicators in an adult population presenting in primary care with LBP and leg pain with or without nerve root involvement.

Project description:The purpose of this study was to define and select a core set of outcome-based quality indicators, accepted by stakeholders on usability and perceived added value as a quality improvement tool, and to formulate recommendations for the next implementation step. In phase 1, 15 potential quality indicators were defined for patient-reported outcome measures and associated domains, namely the Numeric Pain Rating Scale (NPRS) for pain intensity, the Patient Specific Functioning Scale (PSFS) for physical activity, the Quebec Back Pain Disability Scale for physical functioning, and the Global Perceived Effect-Dutch Version for perceived effect. Their comparability and discriminatory characteristics were described using cohort data. In phase 2, a core set of quality indicators was selected based on consensus among stakeholders in focus group meetings. In total, 65,815 completed treatment episodes for patients with nonspecific low back pain were provided by 1009 physical therapists from 219 physical therapist practices. The discriminability between physical therapists of all potential 15 quality indicators was adequate, with intraclass correlation coefficients between 0.08 and 0.30. Stakeholders selected a final core set of 6 quality indicators: 2 process indicators (the routine measurement of NPRS and the PSFS) and 4 outcome indicators (pretreatment and posttreatment change scores for the NPRS, PSFS, Quebec Back Pain Disability Scale, and the minimal clinically important difference of the Global Perceived Effect-Dutch Version). This study described and selected a core set of outcome-based quality indicators for physical therapy in patients with nonspecific low back pain. The set was accepted by stakeholders for having added value for daily practice in physical therapy primary care and was found useful for quality improvement initiatives. Further studies need to focus on improvement of using the core set of outcome-based quality indicators as a quality monitoring and evaluation instrument. Patient-reported outcome-based quality indicators developed from routinely collected clinical data are promising for use in quality improvement in daily practice.

Project description:BACKGROUND:The STarT Back strategy for categorizing and treating patients with low back pain (LBP) improved patients' function while reducing costs in England. OBJECTIVE:This trial evaluated the effect of implementing an adaptation of this approach in a US setting. DESIGN:The Matching Appropriate Treatments to Consumer Healthcare needs (MATCH) trial was a pragmatic cluster randomized trial with a pre-intervention baseline period. Six primary care clinics were pair randomized, three to training in the STarT Back strategy and three to serve as controls. PARTICIPANTS:Adults receiving primary care for non-specific LBP were invited to provide data 2 weeks after their primary care visit and follow-up data 2 and 6 months (primary endpoint) later. INTERVENTIONS:The STarT Back risk-stratification strategy matches treatments for LBP to physical and psychosocial obstacles to recovery using patient-reported data (the STarT Back Tool) to categorize patients' risk of persistent disabling pain. Primary care clinicians in the intervention clinics attended six didactic sessions to improve their understanding LBP management and received in-person training in the use of the tool that had been incorporated into the electronic health record (EHR). Physical therapists received 5 days of intensive training. Control clinics received no training. MAIN MEASURES:Primary outcomes were back-related physical function and pain severity. Intervention effects were estimated by comparing mean changes in patient outcomes after 2 and 6 months between intervention and control clinics. Differences in change scores by trial arm and time period were estimated using linear mixed effect models. Secondary outcomes included healthcare utilization. KEY RESULTS:Although clinicians used the tool for about half of their patients, they did not change the treatments they recommended. The intervention had no significant effect on patient outcomes or healthcare use. CONCLUSIONS:A resource-intensive intervention to support stratified care for LBP in a US healthcare setting had no effect on patient outcomes or healthcare use. TRIAL REGISTRATION:National Clinical Trial Number NCT02286141.

Project description:IntroductionLow back pain (LBP) is the most prevalent musculoskeletal condition worldwide and it is responsible for high healthcare costs and resources consumption. It represents a challenge for primary care services that struggle to implement evidence-based practice. Models of care (MoCs) are arising as effective solutions to overcome this problem, leading to better health outcomes. Although there is growing evidence regarding MoCs for the management of LBP patients, an analysis of the existing body of evidence has not yet been carried out. Therefore, this scoping review aims to identify and map the current evidence about the implementation of MoCs for LBP in primary healthcare. Findings from this study will inform policy makers, health professionals and researchers about their characteristics and outcomes, guiding future research and best practice models.Methods and analysisThis protocol will follow the Joanna Briggs Institute methodological guidelines for scoping reviews. Studies that implemented an MoC for LBP patients in primary healthcare will be included. Searches will be conducted on PubMed, EMBASE, Cochrane Central Register of Controlled Trials, PEDro, Scopus, Web of Science, grey literature databases and relevant organisations websites. This review will consider records from 2000, written in English, Portuguese or Spanish. Two researchers will independently screen all citations and full-text articles and abstract data. Data extracted will include the identification of the MoC, key elements of the intervention, organisational components, context-specific factors and patient-related, system-related and implementation-related outcomes.Ethics and disseminationAs a secondary analysis, this study does not require ethical approval. It will provide a comprehensive understanding on existing MoCs for LBP, outcomes and context-related challenges that may influence implementation in primary healthcare, which is meaningful knowledge to inform future research in this field. Findings will be disseminated through research papers in peer-reviewed journals, presentations at relevant conferences and documentation for professional organisations and stakeholders.

Project description:BackgroundBack pain is one of the UK's costliest and least understood health problems, whose prevalence still seems to be increasing. Educational interventions for general practitioners on back pain appear to have had little impact on practice, but these did not include quality improvement learning, involve patients in the learning, record costs or document practice activities as well as patient outcomes.MethodsWe assessed the outcome of providing information about quality improvement techniques and evidence-based practice for back pain using the Clinical Value Compass. This included clinical outcomes (Roland and Morris Disability Questionnaire), functional outcomes, costs of care and patient satisfaction. We provided workshops which used an action learning approach and collected before and after data on routine practice activity from practice electronic databases. In parallel, we studied outcomes in a separate cohort of patients with acute and sub-acute non-specific back pain recruited from the same practices over the same time period. Patient data were analysed as a prospective, split-cohort study with assessments at baseline and eight weeks following the first consultation.ResultsData for 1014 patients were recorded in the practice database study, and 101 patients in the prospective cohort study. We found that practice activities, costs and patient outcomes changed little after the intervention. However, the intervention was associated with a small, but statistically significant reduction in disability in female patients. Additionally, baseline disability, downheartedness, self-rated health and leg pain had small but statistically significant effects (p < 0.05) on follow-up disability scores in some subgroups.ConclusionsGP education for back pain that both includes health improvement methodologies and involves patients may yield additional benefits for some patients without large changes in patterns of practice activity. The effects in this study were small and limited and the reasons for them remain obscure. However, such is the impact of back pain and its frequency of consultation in general practice that this kind of improvement methodology deserves further consideration.Trial registration numberISRCTN: ISRCTN30420389.
