ABSTRACT
Large variation exists in the monitoring of clinical outcome domains in patients with persistent spinal pain syndrome (PSPS). Furthermore, it is unclear which outcome domains are important from the PSPS patient's perspective. The study objectives were to identify patient-relevant outcome domains for PSPS and to establish a PSPS outcomes framework. PubMed, CINAHL, Cochrane, and EMBASE were searched to identify studies reporting views or preferences of PSPS patients on outcome domains. The Arksey and O'Malley framework was followed to identify outcome domains. An expert panel rated the domains based on the importance for PSPS patients they have treated. A framework of relevant outcome domains was established using the selected outcome domains by the expert panel. No studies were found for PSPS type 1. Five studies with 77 PSPS type 2 patients were included for further analysis. Fourteen outcome domains were identified. An expert panel, including 27 clinical experts, reached consensus on the domains pain, daily activities, perspective of life, social participation, mobility, mood, self-reliance, and sleep. Eleven domains were included in the PSPS type 2 outcomes framework. This framework is illustrative of a more holistic perspective and should be used to improve the evaluation of care for PSPS type 2 patients. Further research is needed on the prioritization of relevant outcome domains.
ABSTRACT
RATIONALE: To optimize results with spinal cord stimulation (SCS) for chronic low back pain (CLBP) and/or leg pain, including persistent spinal pain syndrome (PSPS), careful patient selection based on proved predictive factors is essential. Unfortunately, the necessary selection process required to optimize outcomes of SCS remains challenging. OBJECTIVE: This review aimed to evaluate predictive factors of clinically relevant pain relief after SCS for patients with CLBP and/or radicular leg pain, including PSPS. MATERIALS AND METHODS: In August 2023, PubMed, Cinahl, Cochrane, and EMBASE were searched to identify studies published between January 2010 and August 2023. Studies reporting the percentage of patients with ≥50% pain relief after SCS in patients with CLBP and leg pain, including PSPS at 12 or 24 months, were included. Meta-analysis was conducted to pool results for back, leg, and general pain relief. Predictive factors for pain relief after 12 months were examined using univariable and multivariable meta-regression. RESULTS: A total of 27 studies (2220 patients) were included for further analysis. The mean percentages of patients with substantial pain relief were 68% for leg pain, 63% for back pain, and 73% for general pain at 12 months follow-up, and 63% for leg pain, 59% for back pain, and 71% for general pain at 24 months follow-up assessment. The implantation method and baseline Oswestry Disability Index made the multivariable meta-regression model for ≥50% back pain relief. Sex and pain duration made the final model for ≥50% leg pain relief. Variable stimulation and implantation method made the final model for general pain relief. CONCLUSIONS: This review supports SCS as an effective pain-relieving treatment for CLBP and/or leg pain, and models were developed to predict substantial back and leg pain relief. To provide high-grade evidence for predictive factors, SCS studies of high quality are needed in which standardized factors predictive of SCS success, based on in-patient improvements, are monitored and reported.

BACKGROUND: Rising healthcare costs, an increasing general practitioner shortage and an aging population have made healthcare organization transformation a priority. To meet these challenges, traditional roles of non-medical members have been reconsidered. Within the domain of physiotherapy, there has been significant interest in Extended Scope Physiotherapy (ESP). Although studies have focused on the perceptions of different stakeholders in relation to ESP, there is a large variety in the interpretation of ESP. AIM: To identify a paradigm of ESP incorporating goals, roles and tasks, to provide a consistent approach for the implementation of ESP in primary care. METHODS: An exploratory, qualitative multi-step design was used containing a scoping review, focus groups and semi-structured interviews. The study population consisted of patients, physiotherapists, general practitioners and indirect stakeholders such as lecturers, health insurers and policymakers related to primary care physiotherapy. The main topics discussed in the focus groups and semi-structured interviews were the goals, skills and roles affiliated with ESP. The 'framework' method, developed by Ritchie & Spencer, was used as analytical approach to refine the framework. RESULTS: Two focus groups and twelve semi-structured interviews were conducted to explore stakeholder perspectives on ESP in Dutch primary care. A total of 11 physiotherapists, six general practitioners, five patients and four indirect stakeholders participated in the study. There was a lot of support for 'decreasing healthcare costs', 'tackling increased health demand' and 'improving healthcare effectiveness' as main goals of ESP. The most agreement was reached on 'triaging', 'referring to specialists' and 'ordering diagnostic imaging' as tasks fitting for ESP. Most stakeholders also supported 'working in a multidisciplinary team', 'working as a consultant' and 'an ESP role separated from a physiotherapist role' as roles of ESP. CONCLUSIONS: Based on the scoping review, focus groups and interviews with direct and indirect stakeholders, it appears that there is sufficient support for ESP in the Netherlands. This study provides a clear presentation of how ESP can be conceptualized in primary care. A pilot focused on determining the feasibility of ESP in Dutch primary care will be the next step.
