Background. FORECAST is a prospective longitudinal cohort study exploring mechanism-based prognostic factors for pain persistence in sciatica. Here, we share an update on this largest deeply-phenotyped primary care sciatica cohort. Methods/results. Our cohort includes 180 people with sciatica (score >4 on Stynes’ Sum Score), aged 18–85, within 3 months of symptom onset. Psychosocial factors, self-reported sensory profiling, clinical examination, quantitative sensory testing (QST), biological samples (blood and skin samples), and Magnetic Resonance Neurography of lumbar nerve roots were collected at baseline. Pain persistence was determined at three and twelve months with the Sciatica Bothersomeness Index (SBI) and a numeric pain rating scale (NRS) as primary outcomes. Recruitment nears completion, with 160 participants enrolled to date. 127 and 96 participants have completed 3 and 12 months follow-up respectively. Overall, 56% of our cohort are female, with a mean age (SD) of 54.14yrs (16.57). Ethnicity data approximates local populations. SBI at baseline was (median [IQR]) 13[10-17], and interim longitudinal data shows stepwise improvement at 3 and 12 months. Baseline ‘average’ pain intensity was 5.56 (2.15) for leg pain, and 4.14(2.82) for low back pain (LBP). Overall, pain scores decreased at 3 and 12 months, with greater reductions in leg pain than LBP at 12 months. However, around 55–80% and 40–65% of people reported persistent pain at 3 and 12 months respectively. Conclusion. Leg pain severity was moderate and higher than LBP at baseline. All primary outcome measures demonstrate improvement over time, however 40–65% of patients report persistent pain at 12 months. Conflicts of interest.

Background. Involving research users in setting priorities for research is essential to ensure research outcomes are patient-centred and to maximise research value and impact. The Musculoskeletal (MSK) Disorders Research Advisory Group Versus Arthritis led a research priority setting exercise across MSK disorders. Methods. The Child Health and Nutrition Research Initiative (CHRNI) method of setting research priorities with a range of stakeholders were utilised. The MSKD RAG identified, through consensus, four research Domains: Mechanisms of Disease; Diagnosis and Impact; Living Well with MSK disorders and Successful Translation. Following ethical approval, the research priority exercise involved four stages and two surveys, to: 1) gather research uncertainties; 2) consolidate these; 3) score uncertainties using agreed criteria of importance and impact on a score of 1–10; and 4) analyse scoring, for prioritisation. Results. The first survey had 209 respondents, who described 1290 research uncertainties, which were refined into 68 research questions. 285 people responded to the second survey. The largest group of respondents represented patients and carers, followed by researchers and healthcare professionals. A ranked list was produced, with scores ranging between 12 and 18. Key priorities included developing and testing new treatments, better targeting of treatments, early diagnosis, prevention and better understanding and management of pain, with an emphasis on understanding underpinning mechanisms. Conclusions. For the first time, we have summarised priorities for research across MSKD, from discovery science to applied clinical and health research, including translation. We present a call to action to researchers and
Background. It has become increasingly important to conduct studies assessing clinical outcomes, reoperation rates, and revision rates to better define the indications and efficacy of lumbar spinal procedures and its association with symptomatic adjacent segment degeneration (sASD). Adjacent segment degeneration (ASD) is defined as the radiographic change in the intervertebral discs adjacent to the surgically treated spinal level. SASD represents adjacent segment degeneration which causes pain or numbness due to post-operative spinal instability or nerve compression at the same level. The most common reason for early reoperation and late operation is sASD, therefore is in our best interest to understand the causes of ASD and make steps to limit the occurrence. Method. A comprehensive literature search was performed selecting Randomized controlled trials (RCTs) and retrospective or prospective studies published up to December 2023. Meta-analysis was performed on 38 studies that met the inclusion criteria and included data of clinical outcomes of patients who had degenerative disc disease, disc herniation, radiculopathy, and spondylolisthesis and underwent lumbar fusion or motion-preservation device surgery; and reported on the prevalence of ASD, sASD, reoperation rate, visual analogue score (VAS), and Oswestry disability index (ODI) improvement. Results. When compared to fusion surgery, a significant reduction of ASD, sASD and reoperation was observed in the cohort of patients that underwent motion-preserving surgery. Conclusion. Dynamic fusion constructs are treatment options that may help to prevent sASD. Conflicts of interest. This research was
Background. Our current research aims to develop technologies to predict spinal loads in vivo using a combination of imaging and modelling methods. To ensure the project's success and inform future applications of the technology, we sought to understand the opinions and perspectives of patients and the public. Methods. A 90-minute public and patient involvement event was developed in collaboration with Exeter Science Centre and held on World Spine Day 2023. The event involved a brief introduction to the project goals followed by an interactive questionnaire to gauge the participants’ background knowledge and interest. The participants then discussed five topics: communication, future directions of the research, concerns about the research protocol, concerns about data, and interest in the project team and research process. A final questionnaire was used to determine their thoughts about the event. Results. Twelve adults attended the event, many motivated by their experience or interest in back pain. A thematic analysis was used to review participant comments on the research project, identifying the need to relate the research to everyday life, present risks in various ways, and be transparent about
Purpose and Background. Clinical practice guidelines (CPGs) recommend self-management for low back pain (LBP). Our recent narrative review on self-management needs revealed a consensus with respect to the critical components of self-management interventions. With mobile health advancements, apps offer innovative support for LBP management. This study aims to identify current apps for the self-management of LBP, assessing them for their quality, intervention content, theoretical approaches, and risk management approaches. Methods and Results. We identified 69 apps for LBP self-management from a systematic search in the UK iTunes and Google Play stores. The most recommended interventions are muscle stretching (n=51, 73.9%), muscle strengthening (n=42, 60.9%), and core stability exercises (n=32, 46.4%). The average MARS (SD) overall score for the included apps was 2.4 (0.44) out of a possible 5 points, with the engagement and information dimension scoring the lowest at 2.1. In terms of theoretical and risk management approaches, no apps offered a theoretical care model and all failed to specify the age group targeted; only one (1.4%) provided a tailored care approach; 18 (26.1%) included intervention progression; and 11 (15.9%) reported management safety checks. Conclusion. This study shows that app developers generally select interventions endorsed by CPGs. However, the application of a biopsychosocial care model is not being considered. Most of them are of low quality, lacking theoretical approaches to care and consideration of associated risks. It is essential to involve clinicians and patients in developing LBP self-management apps to improve the quality and related approach. Conflicts of interest. None. Sources of
Background and study purpose. A recent systematic review with meta-analysis of eight randomised controlled trials concluded that Cognitive Functional Therapy (CFT) for low back pain might be effective in reducing disability, pain and fear-avoidance beliefs. However, the descriptions of a CFT intervention are not always clear. This study aimed to rate the replicability of the CFT interventions and control groups in the systematic review. Methods. Two reviewers independently extracted data from the study articles, protocols and appendices into Microsoft Excel using the Template for Intervention Description and Replication (TIDieR) checklist. This checklist has 12 items to describe the ‘why’, ‘what’, ‘who’, ‘how’, ‘where’, ‘when and how much’, ‘tailoring’, ‘modifications’, and ‘how well’ for each intervention. We rated the replicability of the CFT interventions and control groups as ‘reported’, ‘partially reported’ and ‘not reported’ and resolved discrepancies by consensus. Results. No studies reported 100% of the TIDieR items; the mean ‘reported’ rating was 54% (range 33–67%) for the CFT interventions and 35% (range 8–67%) for controls. The six most replicable items were the same for both CFT and control groups. These were ‘brief name’ (CFT=100%; control=100%), ‘why’ (CFT=100%; control=50%), ‘how’ (CFT=100%; control=50%), ‘what procedures’ (CFT=88%; control=63%), ‘where’ (CFT=88%; control=75%) and ‘planned adherence’ (CFT=75%; control=38%). Items that were not sufficiently ‘reported’ for either CFT or control groups included ‘when and how much’, ‘tailoring’ and ‘adherence’. Conclusion. Incomplete descriptions of CFT interventions mean that clinicians and patients cannot implement those that have demonstrated effectiveness, and poor descriptions of control groups prevent researchers from replicating them in future studies.

Background. Disability is an important multifaceted construct. Identifying sources of disability could help optimise patient care. The aim of this study was to test an approach that not only estimates severity of disability, but also identifies the source(s) of this disability. Methods. An online survey was used to collect data from a convenience sample, recruited via email and social media invitations. Two generic measures of disability, the 8-item Universal Disability Index (UDI8) and Groningen Activity Restriction Scale (GARS) were used to estimate the prevalence and severity of disability in this sample. Non-zero UDI8 item responses generated conditional sub-questions, in which participants could attribute their activity limitations to one or more sources (pain, fatigue, worry, mood, and other). This allowed for a decomposition of UDI8 scores into source components. Results. 403 participants enrolled; 334 completed all UDI8 and GARS items. Of these, 85.3% (285/334) reported at least one restricted activity via the UDI8, while 43.4% (145/334) reported some reduced independence via the GARS. Disability severity increased with age until approximately 40 years, after which it decreased gradually. Pain component scores were high in all individuals with higher and lower disability severity, whereas fatigue component scores were highest in individuals reporting higher disability severity. Worry, mood, and other component scores were not high at any level of disability severity. Conclusions. This approach should be used to identify the prevalence, severity and sources of disability in the general population and in specific patient groups. Conflicts of interest. No conflicts of interest.

Background. The association between lumbar intervertebral disc degeneration (LDD) and low back pain (LBP) is modest. We have recently shown that genetic propensity to pain is an effect modifier of the LDD-LBP relationship when LDD is defined as a summary score of LDD (LSUM), suggesting the association may be driven by individuals with the greatest genetic predisposition to pain. This study examined the association between individual spine magnetic resonance imaging (MRI)-determined LDD features and LBP in subgroups defined by genetic predisposition to pain. Method. We developed a polygenic risk score (PRS) for “genetic propensity to pain” defined as the number of non-back pain locations (head, face, neck/shoulder, stomach/abdomen, hip, and knee) with duration ≥3 months in 377,538 UK Biobank participants of European ancestry. This PRS was used to stratify TwinsUK MRI samples (n=645) into four strata of genetic propensity to pain. We examined the association between LBP and MRI features of lumbar disc height, disc signal intensity, disc bulge, and osteophytes with adjustments for age, sex, PRS strata, interaction terms for each MRI feature x PRS strata, and twin status. Results. We found significant effect modification of the LDD-LBP relationship by genetic propensity to pain for the lumbar MRI features of disc height (p=0.03 for the interaction term with highest quartile of genetically-predicted propensity to pain) and disc signal intensity (p=0.001), but not for disc bulge and osteophytes. Conclusion. Genetic propensity to pain modifies the association between individual LDD features and LBP and should be considered in LBP clinical studies. Conflicts of interest.

Purpose and background of the study. Self-management and behaviour change is at the core of back pain management. Despite the high-rate of recurrence and healthcare utilisation, clinical guidelines do not include guidance for clinicians on return consultations. This project aimed to identify primary care clinicians’ reported practices and experiences of delivering self-management advice for people returning with persistent low back pain (LBP), to inform future delivery of self-management care. Methods and Results. In this qualitative study involving 27 primary care clinicians, four focus groups and two semi-structure interviews were conducted online. GPs (n=5) and physiotherapists working in primary care roles (First contact practitioners n=7, community and interface roles n=7, and mixed roles n=8) in England and Scotland shared their experience of delivering self-management advice to people returning with persistent LBP. Video recordings were transcribed verbatim and analysed with reflexive thematic analysis. Clinicians unanimously shared their frustrations identifying the challenges involved in supporting people who return with LBP. Helpful strategies to support self-management in return consultations were identified by clinicians in addition to service and system-level changes vital to optimise care. Patient-factors affecting delivery of care, lack of defined responsibility and challenges in meeting patients’ expectations illustrated the tensions that exist in return consultations. Conclusion. This novel study provides insight into the experiences and practices of the frontline primary care workforce seeing patients return with persistent or recurrent LBP. It identifies the tensions that exist between services, professional roles and between clinicians and patients regarding self-management. Important practice implications have been identified to improve information-sharing, agenda-setting, and exploring expectations. No conflicts of interest. . Source of
Background. Disability is an important multifaceted construct. The aim of this study was to develop and evaluate a brief, generic self-reported disability questionnaire: the Universal Disability Index (UDI). Methods. Convenience sampling was used to collect general population data via an online survey. Data were randomly divided into training and validation subsets. The dimensionality and structure of eight UDI questionnaire items were evaluated using exploratory factor analysis (EFA, training subset) followed by confirmatory factor analysis (CFA, validation subset). To assess concurrent validity, the UDI summed score from the full dataset was compared to the Groningen Activity Restriction Scale (GARS) and the Graded Chronic Pain Scale (GCPS) disability scores. Internal consistency was also assessed. Results. 403 participants enrolled; 364 completed at least one UDI item. Three single-factor versions of the UDI were assessed (8-item, 7-item, and 6-item). All versions performed well during EFA and CFA (182 cases assigned to each), but none met the RMSEA (Root Mean Square Error of Approximation) criterion (≤ 0.08). All versions of the UDI had high internal consistency (Cronbach's α > 0.90) and were strongly correlated (Pearson's r > 0.7) with both GARS and GCPS disability scores, indicating concurrent validity. Conclusions. A brief, generic self-reported disability questionnaire was found to be valid and to possess good psychometric properties. The UDI has a single factor structure and either a 6-item, 7-item or 8-item version can be used to measure disability. For brevity and parsimony, the 6-item UDI is recommended, but further testing of all versions is warranted. Conflicts of interest. No conflicts of interest. Sources of
Introduction. Lumbosacral transitional vertebrae (LSTV) are increasingly recognized as a common anatomical variant and is the most common congenital anomaly of the lumbosacral spine. Patients can have symptomatic LSTV, known as Bertolotti's Syndrome, where transitional anatomy can cause back, L5 distribution leg, hip, and groin pain. We propose an outline for diagnosis and treatment of Bertolotti's Syndrome. Methods. We retrospectively reviewed over 500 patients presenting to the primary author with low back, buttock, hip, groin and/or leg pain from April 2009 through April 2024. Patients with radiographic findings of an LSTV and clinical presentation underwent diagnostic injections to confirm diagnosis of Bertolotti's syndrome. Treatment was determined based on patient's LSTV classification. 157 patients with confirmed Bertolotti's syndrome underwent surgical treatment. Results. Over 500 patients presented with an appropriate clinical presentation and radiographic findings of an LSTV. Diagnostic injections were targeted into the transitional anatomy confirming the LSTV as the primary pain generator to make the diagnosis of Bertolotti's syndrome. The decision in the type of surgical intervention, resection or fusion, was made based on patient's LSTV anatomy. 157 patients with confirmed Bertolotti's Syndrome underwent surgical treatment (121 fusions (77%), 36 resections (23%)). The classification system and surgical outcomes, in part, have been previously published in World Neurosurgery. Conclusion. We have outlined the best practice of diagnosis and treatment selection for Bertolotti's syndrome. We have shown significant improvement in outcomes based on this method. We hope to aid in both patient education and provide an outline on how clinicians can become knowledgeable on Bertolotti's syndrome. Conflicts of interest. No conflicts of interest. Sources of
Introduction. Vertebral compression fractures are the most common type of osteoporotic fracture. Though 89% of clinical fractures occur anteriorly, it is challenging to replicate these ex vivo with the underlying intervertebral discs (IVDs) present. Furthermore, the role of disc degeneration in this mechanism is poorly understood. Understanding how disc morphology alters vertebral strain distributions may lead to the utilisation of IVD metrics in fracture prediction, or inform surgical decision-making regarding instrumentation type and placement. Aim. To determine the effect of disc degeneration on the vertebral trabecular bone strain distributions in axial compression and flexion loading. Methods. Eight cadaveric thoracolumbar segments (T11-L3) were prepared (N=4 axial compression, N=4 flexion). µCT-based digital volume correlation was used to quantify trabecular strains. A bespoke loading device fixed specimens at the resultant displacement when loaded to 50N and 800N. Flexion was achieved by adding 6° wedges. Disc degeneration was quantified with Pfirrmann grading and T2 relaxation times. Results. Anterior axial strains were 80.9±39% higher than the posterior region in flexion (p<0.01), the ratio of which was correlated with T2 relaxation time (R. 2. =0.80, p<0.05). In flexion, the central-to-peripheral axial strain ratio in the endplate region was significantly higher when the underlying IVDs were non-degenerated relative to degenerated (+38.1±12%, p<0.05). No significant differences were observed in axial compression. Conclusion. Disc degeneration is a stronger determinant of the trabecular strain distribution when flexion is applied. Load transfer through non-degenerate IVDs under flexion appears to be more centralised, suggesting that disc degeneration predisposes flexion-type compression fractures by shifting high strains anteriorly.

Introduction. Multiple studies have identified Cutibacterium acnes (C.acnes) and other microbes in intervertebral disc tissue using 16S DNA Sequencing and microbial cultures. However, it remains unclear whether these bacteria are native to the discs or result from perioperative contamination. Our study aimed to detect Gram-positive bacteria in non-herniated human disc samples and explore correlations with Toll-like receptors (TLR) 2, TLR4, NLRP3, and Gasdermin D. Methods. Immunohistochemical staining was conducted on 75 human IVD samples for Gram-positive bacteria, S. aureus, C.acnes, TLR2, TLR4, NLRP3, and Gasdermin D. Cell detection and classification were performed using QuPath. NP cells were treated with Lipopolysaccharide (LPS) and Peptidoglycan (PGN) in monolayer and alginate beads for up to 72 hours, followed by secretome analysis using Luminex. Statistical analysis included Kruskal-Wallis, Dunn's multiple comparison test, and Pearson correlation. Results. Immunohistochemical staining revealed Gram-positive bacteria exclusively within cells, with C. acnes positivity ranging from 5–99% and correlating with patient age (r=0.41, p= 0.007). TLR2 positivity ranged from 5–99% and TLR4 from 3–72%, showing a strong correlation (r= 0.62, p= 1.5e-006). Females with mid-degenerative grades exhibited significantly decreased TLR2 expression compared to those without degeneration signs. Treatment with LPS and PGN increased catabolic cyto- and chemokines associated with IVD degeneration. Conclusion. In conclusion, this study confirms Gram-positive bacteria presence in non-herniated human disc samples and highlights their role in triggering a catabolic response in disc cells.

Objectives. Understanding lumbar facet joint involvement and biomechanical changes post spinal fusion is limited. This study aimed to establish an in vitro model assessing mechanical effects of fusion on human lumbar facet joints, employing synchronized motion, pressure, and stiffness analysis. Methods and Results. Seven human lumbar spinal units (age 54 to 92, ethics 15/YH/0096) underwent fusion via a partial nucleotomy model mimicking a lateral cage approach with PMMA cement injection. Mechanical testing pre and post-fusion included measuring compressive displacement and load, local motion capture, and pressure mapping at the facet joints. pQCT imaging (82 microns isotropic) was carried out at each stage to assess the integrity of the vertebral endplates and quantify the amount of cement injected. Before fusion, relative facet joint displacement (6.5 ± 4.1 mm) at maximum load (1.1 kN) exceeded crosshead displacement (3.9 ± 1.5 mm), with loads transferred across both facet joints. After fusion, facet displacement (2.0 ± 1.2 mm) reduced compared to pre-fusion, as was the crosshead displacement (2.2 ± 0.6 mm). Post-fusion loads (71.4 ± 73.2 N) transferred were reduced compared to pre-fusion levels (194.5 ± 125.4 N). Analysis of CT images showed no endplate damage post-fusion, whilst the IVD tissue: cement volume ratio did not correlate with the post-fusion behaviour of the specimens. Conclusion. An in vitro model showed significant facet movement reduction with stand-alone interbody cage placement. This technique identifies changes in facet movement post-fusion, potentially contributing to subsequent spinal degeneration, highlighting its utility in biomechanical assessment.

Background and study purpose. Low back pain with no identified underlying cause is categorised as primary musculoskeletal pain by the International Association for the Study of Pain. In April 2021, the National Institute for Care and Excellence (NICE) published updated guidance for the management of primary chronic pain conditions in England. As part of the De-STRESS pain study, we explored the perspectives of GPs on the updated guideline and impact upon clinical practice. Methods and results. Semi-structured interviews were conducted with 21 GPs in England. Data were analysed using thematic analysis and constant comparison techniques. GPs agreed with the recommendations restricting pharmacological options for pain management and reflected that they now had an expert reference to back-up their decision-making and could use the guidance in potentially difficult conversations with patients. Frustration was expressed by GPs about the lack of alternative options to medication, as the non-pharmacological recommendations were difficult to implement, had lengthy waiting lists, or were unavailable in their locality. Conclusion. Although GPs discussed benefits of the updated NICE guideline in potentially reducing prescriptions of ineffective and potentially harmful medications, frustration about the lack of alternative strategies added to the difficulties encountered in managing people with persistent back pain in primary care.

Purpose and Background. Patients with low back pain are increasing globally. Physical dysfunction and psychosocial factors such as stress, anxiety, and fear of movement, often referred to as yellow flags, play a role in the persistence of low back pain. What is not known is the extent to which yellow flags are screened for and treatment adjusted accordingly by Physiotherapists in India. The aim was to determine the current knowledge and awareness of physiotherapists in India regarding psychosocial factors for managing patients with low back pain. Methods. Semi-structured interviews gathered data from of six physiotherapists, The interviews were conducted online. The data was transcribed and analysed using thematic analysis. Results. The main finding was that the physiotherapists in India had a limited knowledge regarding psychosocial factors for management of low back pain. They were not supportive of adding yellow flag screening into their routine treatments due to lack of t awareness of such screening tools Physical elements of low back pain were focused on during treatment by the therapists and recommended by management. The physiotherapists noted that high daily patient volume left them with limited time to alter treatment protocols. Conclusion. There appears to be limited information and education delivered to the physiotherapists in India regarding psychosocial factors for managing low back pain. The addition of these factors in the education and treatment protocols could address these important factors when managing patients with low back pain in India.

Background. Chronic back pain (CBP) is a major cause of disability globally and its causes are multifactorial. Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) are human herpes viruses usually acquired in early life. About 50% and over 90% of the population worldwide have been infected with CMV and EBV, respectively. This study investigated a potential causal relationship between CMV infection and CBP. Method. UK Biobank participants provided information on CMV seropositivity and CBP status, which were available for both traits in 5,140 participants. We used EBV seropositivity as a negative control to identify confounding and inaccurate causal inference. A one-sample Mendelian randomization (MR) based on independent genetic variants predicting CMV and EBV positivity was conducted in Northern European participants. To validate the association further, the MR study was repeated using a CMV polygenic risk score (PRS). Results. CMV GWAS revealed 86 independent SNPs having p-value < 2 × 10. −4. for the one-sample MR. These SNPs were used to define genetically-predicted categories of CMV infection risk. CMV infection risk categories were significantly associated with CBP (OR = 1.150; 95% CI: 1.005–1.317, p-value = 0.043), findings which were confirmed using the CMV PRS (OR = 1.299; 95% CI: 1.141–1.479, p-value = 0.001). There was no causal association between EBV and CBP (p-value = 0.17). Conclusion. Our results provide further evidence for a causal relationship between CMV infection and CBP. These results suggest a stratified approach to CBP may be useful, particularly in clinical trials and they shed light on underlying mechanisms in CBP. Conflicts of interest. No conflicts of interest.

Background. Low back pain can lead to neuroplastic changes in the central nervous system, known as nociplastic pain. As nociplastic pain may be provoked by premorbid sensory profiles, such profiles may be prognostic in the development of nociplastic pain over time. Objectives. To investigate whether four sensory profiles are prognostic in the development of symptoms of nociplastic pain in people with acute low back pain. Methods. A longitudinal type 2 prognostic factor research study was performed in accordance with the PROGRESS framework, using a baseline and a follow-up after 12 weeks, between the Adolescent/Adult Sensory Profile and the Central Sensitisation Inventory. Study participants were consecutively included from primary care physiotherapy practices randomly spread throughout the Netherlands. A multivariable regression analysis was performed to adjust sensory profiles by the level of pain, disability, age, and duration of low back pain. Results. After adjustment Low Registration B=0.41, 95%CI (0.37, 0.99), Sensory Seeking B=0.37, 95%CI (0.24, 0.73), Sensory Sensitive B=0.51, 95%CI (0.50, 1.06), Sensation Avoiding B=0.46, 95%CI (0.43, 0.99) were significantly associated with the development of nociplastic pain symptoms. Conclusion. Sensory profiles in people with acute low back pain predict symptoms of nociplastic pain after 12 weeks. Conflict of interest: No conflict of interest. Sources of
Purpose of study and background. Spinal surgery is a high-risk surgical speciality, a patient's understanding of surgical interventions, alternative treatment options, and the benefits and risks must be ascertained to gain informed consent. This pilot study aims to evaluate if the provision of a digital recording of a patient's consultation enhances patient satisfaction, improves recall of clinical diagnosis, recall of treatment options and the risks and benefits of Spinal Surgery. Methodology and results. A coalition team was identified. A safe and secure process for recording and storage identified. Both qualitative and quantitative data was collected via questionnaires. 62 patients were invited to participate in the pilot, 12 declined. Data was collected immediately post consultation, and two weeks following the consultation via telephone. Comparison was made of the relative increase or decrease in patient recall of the clinical diagnosis, treatment options, and the benefits and the risks of spinal surgery. Patient satisfaction was measured pre- and post- consultation. 50 patients (81%) participated. 32 participants (52%) responded to follow up questionnaire at 2 weeks. Recall of risk for surgical intervention increased by 37%, and of benefit by 36%. Patient satisfaction was rated excellent or very satisfied in 93% at initial consultation and at 2 week follow up all participant's rated satisfaction as excellent or very satisfied. Conclusion. This pilot study was small. COVID delayed further recruitment. Initial outcomes demonstrated high levels of patient satisfaction and appear to demonstrate improved recall. Significant technological issues were identified. Further collaborative work needs to be undertaken. Conflicts of interest: No conflicts of interest. Sources of
