Patterns of pain medication usage and self-reported pain in older Irish adults with osteoarthritis: A latent class analysis of data from the Irish Longitudinal Study on Ageing.

BACKGROUND: This study aimed to identify and describe links between pain medication use and self-reported pain among people aged ≥ 50 years with osteoarthritis (OA) in an Irish population, and to examine the relationships between pain, medication usage and socioeconomic and clinical characteristics. METHODS: Secondary data analysis of wave 1 cross-sectional data from The Irish Longitudinal Study on Ageing (TILDA) was undertaken of 1042 people with self-reported doctor-diagnosed OA. We examined use of medications typically included in OA clinical guidelines, including non-opioid analgesics (e.g. paracetamol), topical and oral non-steroidal anti-inflammatory drugs (NSAIDs), opioids and nutraceuticals. Latent Class Analysis (LCA) was used to identify underlying clinical subgroups based on medication usage patterns, and self-reported pain severity. Multinomial logistic regression was used to explore sociodemographic and clinical characteristic links to latent class membership. RESULTS: A total of 358 (34.4%) of the 1042 people in this analysis were taking pain medications including oral NSAIDs (17.5%), analgesics (11.4%) and opioids (8.7%). Nutraceutical (glucosamine/chondroitin) use was reported by 8.6% and topical NSAID use reported by 1.4%. Three latent classes were identified: (1) Low medication use/no pain (n = 382, 37%), (2) low medication use/moderate pain (n = 523, 50%) and (3) moderate medication use/high pain (n = 137, 13%). Poorer self-rated health and greater sleep disturbance were associated with classes 2 and 3; depressive symptoms and female gender were associated with class 2, and retirement associated with class 3. CONCLUSIONS: Whilst pain medication use varied with pain severity, different medication types reported broadly aligned with OA guidelines. The two subgroups exhibiting higher pain levels demonstrated poorer self-rated health and greater sleep disturbance.

The Evolving Role of Artificial Intelligence in Radiotherapy Treatment Planning-A Literature Review.

This paper examines the integration of artificial intelligence (AI) in radiotherapy for cancer treatment. The importance of radiotherapy in cancer management and its time-intensive planning process make AI adoption appealing especially with the escalating demand for radiotherapy. This review highlights the efficacy of AI across medical domains, where it surpasses human capabilities in areas such as cardiology and dermatology. Focusing on radiotherapy, the paper details AI's applications in target segmentation, dose optimization, and outcome prediction. It discusses adaptive radiotherapy's benefits and AI's potential to enhance patient outcomes with much improved treatment accuracy. The paper explores ethical concerns, including data privacy and bias, stressing the need for robust guidelines. Educating healthcare professionals and patients about AI's role is crucial as it acknowledges potential job-role changes and concerns about patients' trust in the use of AI. Overall, the integration of AI in radiotherapy holds transformative potential in streamlining processes, improving outcomes, and reducing costs. AI's potential to reduce healthcare costs underscores its significance with impactful change globally. However, successful implementation hinges on addressing ethical and logistical challenges and fostering collaboration among healthcare professionals and patient population data sets for its optimal utilization. Rigorous education, collaborative efforts, and global data sharing will be the compass guiding its' success in radiotherapy and healthcare.

Veterinary Students' Sense of Belonging: Growing Community with Small Group Academic Enhancement.

A student's sense of belonging to a university is associated with success in academic setting, happiness, and satisfaction. It is therefore unsurprising that universities commonly strive to improve student measures of belonging especially considering its negative correlation with attrition rates. This study documents the implementation and assessment of a new curricular intervention at Ross University School of Veterinary Medicine (RUSVM) and measures associated changes in students' feeling of belonging to the university and accountability for their success. Specifically, small, group, faculty-guided weekly discussion sessions were introduced to the Veterinary Professional Foundation (VPF) course to complement a series of updated didactic only lectures. Voluntary surveys ("belonging to the university scale" [1] and the "personal accountability in education scale" [2]) were utilized to document student attitudes and feelings surrounding these variables. Likert scores from a control group of students who completed the VPF course prior to the curricular change were compared to the intervention group who engaged in the weekly guided discussion sessions via a Wilcoxon test. The intervention group reported significantly improved feelings of belonging to the university (p-values ranging from 0.008 to 0.027). Minimal change was noted between groups associated with accountability. The addition of weekly small group meetings has proven valuable at RUSVM in improving student sense of belonging to the university. Further research is indicated to determine if accountability may be improved over a longer period of monitoring with continued interventions.

Prospective observational study investigating the predictive validity of the STarT Back tool and the clinical effectiveness of stratified care in an emergency department setting.

PURPOSE: To determine the predictive validity of the STarT Back tool (SBT) undertaken at baseline and 6 weeks to classify Emergency Department (ED) patients with LBP into groups at low, medium or high risk of persistent disability at 3 months. A secondary aim was to evaluate the clinical effectiveness of pragmatic risk-matched treatment in an ED cohort at 3 months. METHODS: A prospective observational multi-centre study took place in the physiotherapy services linked to the ED in four teaching hospitals in Dublin, Ireland. Patients were stratified into low, medium and high-risk groups at their baseline assessment. Participants received stratified care, where the content of their treatment was matched to their risk profile. Outcomes completed at baseline and 3 months included pain and disability. Linear regression analyses assessed if baseline or 6-week SBT score were predictive of disability at 3 months. Changes in the primary outcome of disability were dichotomised into those who achieved/ did not achieve a 30% improvement in their RMDQ at 6 weeks and 3 months. RESULTS: The study enrolled 118 patients with a primary complaint of LBP ± leg pain with 67 (56.7%) completing their 6-week and 3-month follow-up. Baseline RMDQ and being in medium or high risk SBT group at 6 weeks were predictive of persistent disability at 3 months. A total of 54 (80.6%) participants reported a > 30% improvement at 3 months. CONCLUSION: Disability at baseline and SBT administered at 6 weeks more accurately predicted disability at 3 months than SBT at baseline in an ED population.

The steroid metabolome of pregnancy, insights into the maintenance of pregnancy and evolution of reproductive traits.

Modes of mammalian reproduction are diverse and not always conserved among related species. Progesterone is universally required to supports pregnancy but sites of synthesis and metabolic pathways vary widely. The steroid metabolome of mid-to late gestation was characterized, focusing on 5α-reduced pregnanes in species representing the Perissodactyla, Cetartiodactyla and Carnivora using mass spectrometry. Metabolomes and steroidogenic enzyme ortholog sequences were used in heirarchial analyses. Steroid metabolite profiles were similar within orders, whales within cetartiodactyls for instance, but with notable exceptions such as rhinoceros clustering with goats, and tapirs with pigs. Steroidogenic enzyme sequence clustering reflected expected evolutionary relationships but once again with exceptions. Human sequences (expected outgroups) clustered with perissodactyl CYP11A1, CYP17A1 and SRD5A1 gene orthologues, forming outgroups only for HSD17B1 and SRD5A2. Spotted hyena CYP19A1 clustered within the Perissodactyla, between rhinoceros and equid orthologues, whereas CYP17A1 clustered within the Carnivora. This variability highlights the random adoption of divergent physiological strategies as pregnancy evolved among genetically similar species.

Physiotherapy management of greater trochanteric pain syndrome (GTPS): an international survey of current physiotherapy practice.

OBJECTIVES: This study aimed to establish and compare current physiotherapy management of GTPS in Australia, New Zealand (NZ) and Ireland. DESIGN: Cross-sectional observational survey of physiotherapists. METHODS: An online survey was distributed to registered musculoskeletal physiotherapists in Australia, NZ and Ireland. Ordinal and nominal data were analysed using frequency counts or mean ranks; median and interquartile ranges were calculated for numerical data. Inter-country comparisons were made using Chi-squared analyses for nominal/ordinal data and Kruskal-Wallis tests for numerical data. Statistical significance was set at P<0.05. RESULTS/FINDINGS: Valid responses were received from 361 physiotherapists, 61% were female and 80% worked in private practice. Overall, consistency in treatment of GTPS was observed across the three countries. All physiotherapists used education and exercise (most commonly strengthening and neuromuscular control) primarily targeting the gluteal muscles. Other interventions included massage (90%), stretching (53%), range of motion (40%), thermal modalities (50%), taping (38%) and electrotherapy (25%), whilst 40% commonly recommended up to 2 to 3 corticosteroid injections per patient/per annum. Physiotherapists used pain severity scales as their primary outcome measure (79%). Single leg stance was the most common physical measure used (68%), and global rating scores or standardised physical measures were less commonly used. CONCLUSION: This international survey established the physiotherapy management of GTPS. Education used in conjunction with exercise is in line with current evidence, but a proportion of clinicians use adjunct treatments without clear rationale or supporting evidence. Results indicate the need to further define optimal management of GTPS using robust methodologies such as randomised controlled trials.

An international survey of current physiotherapy practice in diagnosis and knowledge translation of greater trochanteric pain syndrome (GTPS).

PURPOSE: To evaluate how physiotherapists across three countries (Australia, New Zealand (NZ) and Ireland) diagnose greater trochanteric pain syndrome (GTPS) using clinical tests and imaging findings, and how physiotherapists update their knowledge regarding GTPS. DESIGN: Cross-sectional observational study of physiotherapists. METHODS: An online survey was distributed to registered physiotherapists in Australia, NZ and Ireland. Ordinal and nominal data were analysed using frequency counts or mean ranks; medians and interquartile ranges were calculated for numerical data. Comparisons between the three countries were made using Chi-squared analyses for nominal/ordinal data and Kruskal Wallis tests for numerical data. Statistical significance was set at p < 0.05. RESULTS/FINDINGS: Valid responses were received from 361 physiotherapists; 61% were female and 79.8% worked in private practice. Most respondents were very confident in diagnosing GTPS (67.9%) and incorporated a range of symptoms and tests, including validated tests, in their diagnosis. However, many physiotherapists were not commonly using some available validated diagnostic tests (e.g. FABER and FADER-R). Approximately 30% of physiotherapists used imaging to inform assessment, with ultrasound being most preferred. Physiotherapists rated hands-on experience as most valuable for updating their knowledge of GTPS, followed by courses. CONCLUSION: While most clinicians appear to be using current evidence in their assessment of patients with GTPS, a proportion use suboptimal methods and/or a limited range of diagnostic tests, suggesting that despite their confidence in diagnosis, further knowledge translation may be required. Future research should determine the best methods of facilitating knowledge acquisition and translation of research into practice.

Evaluating the immediate effects of wearing foot orthotics in children with Joint Hypermobility Syndrome (JHS) by analysis of temperospatial parameters of gait and dynamic balance: A preliminary study.

Joint Hypermobility Syndrome (JHS) in children, presents with increased joint range of motion and can lead to altered gait strategies and reduced dynamic balance. Despite limited evidence foot orthoses are sometimes prescribed to patients with JHS with the aim to improve the stability of their gait pattern and theoretically reduce associated symptoms of fatigue and joint pain. The purpose of this study was therefore to analyse the immediate effects of 'off the shelf' orthoses on temporospatial parameters of gait and dynamic balance in this cohort. METHODS: A total of 21 patients were recruited for the study (13 female) with a median age of 10 years (IRQ = 4.12). Each patient had their gait analysed using the GAITRite walkway in their own footwear and immediately after being prescribed the orthoses. Gait was tested at both the patients' preferred speed and when asked to walk slower to challenge their dynamic balance. RESULTS: Gait appeared more synchronised, with a reduction in step length and width variability, when participants were provided with orthotics. The variation was greatest when participants were asked to walk slower. Double stance was significantly less at slower speeds when orthotics were added (1.61%, 95% CI = 0.34, 2.89, p = 0.015) CONCLUSION: Results of this study indicate that orthotics have a definite immediate influence on gait patterns in patients with JHS. Future studies should investigate the long-term effects of orthotics in this population and include outcome measures for symptoms such as pain.

Musculoskeletal services in primary care in the Republic of Ireland: an insight into the perspective of physiotherapists.

OBJECTIVES: With a shift in musculoskeletal physiotherapy from secondary to primary care in Ireland, this study aimed to explore physiotherapists' experiences of providing musculoskeletal physiotherapy in primary care to gain an insight into their changing roles, challenges in service delivery and continuing professional development (CPD) needs. DESIGN: Qualitative design using focus group interviews. SETTING: Primary care physiotherapy services in the Republic of Ireland. PARTICIPANTS: Four focus groups with four junior and 15 senior physiotherapists working in a musculoskeletal public primary care setting took place nationally, representing an urban and rural case mix. RESULTS: Physiotherapists identified significant differences in the provision of musculoskeletal physiotherapy services across primary care sites. A number of environmental barriers were identified that impacted on service delivery, including physical infrastructure, equipment, interaction with acute sites, administration support and engagement in CPD. The role of the physiotherapist in the context of the broader multidisciplinary team also emerged as a theme, as well as the balance between the generalist versus specialist role of the physiotherapist in the primary care setting. CONCLUSIONS: Considerable variation exists in the provision of physiotherapy, and CPD opportunities and support across primary care sites. Future research should focus on pragmatic methods to optimise service delivery and patient care in this setting.

Methyl-CpG-binding protein MBD2 plays a key role in maintenance and spread of DNA methylation at CpG islands and shores in cancer.

Cancer is characterised by DNA hypermethylation and gene silencing of CpG island-associated promoters, including tumour-suppressor genes. The methyl-CpG-binding domain (MBD) family of proteins bind to methylated DNA and can aid in the mediation of gene silencing through interaction with histone deacetylases and histone methyltransferases. However, the mechanisms responsible for eliciting CpG island hypermethylation in cancer, and the potential role that MBD proteins play in modulation of the methylome remain unclear. Our previous work demonstrated that MBD2 preferentially binds to the hypermethylated GSTP1 promoter CpG island in prostate cancer cells. Here, we use functional genetic approaches to investigate if MBD2 plays an active role in reshaping the DNA methylation landscape at this locus and genome-wide. First, we show that loss of MBD2 results in inhibition of both maintenance and spread of de novo methylation of a transfected construct containing the GSTP1 promoter CpG island in prostate cancer cells and Mbd2-/- mouse fibroblasts. De novo methylation was rescued by transient expression of Mbd2 in Mbd2-/- cells. Second, we show that MBD2 depletion triggers significant hypomethylation genome-wide in prostate cancer cells with concomitant loss of MBD2 binding at promoter and enhancer regulatory regions. Finally, CpG islands and shores that become hypomethylated after MBD2 depletion in LNCaP cancer cells show significant hypermethylation in clinical prostate cancer samples, highlighting a potential active role of MBD2 in promoting cancer-specific hypermethylation. Importantly, co-immunoprecipiation of MBD2 shows that MBD2 associates with DNA methyltransferase enzymes 1 and 3A. Together our results demonstrate that MBD2 has a critical role in 'rewriting' the cancer methylome at specific regulatory regions.

Judicious use of prophylactic antimicrobials to reduce abdominal surgical site infections in periparturient cows: part 1 - a risk factor review.

Surgical site infections (SSI) are an uncommon, but significant, consequence of surgical interventions. There are very few studies investigating SSI risk in veterinary medicine, and even fewer in cattle, despite the fact that major surgeries are commonly conducted on livestock. Furthermore, the suboptimal conditions under which such surgeries are frequently performed on livestock could be considered an important risk factor for the development of SSIs. With increasing public concern over the contribution of veterinary-prescribed antimicrobials to the emergence of antimicrobial-resistant bacteria in people, there is widespread scrutiny and criticism of antimicrobial use in livestock production medicine systems. While the causal link between antimicrobial resistance in livestock and people is heavily debated, it is clear that the prevalence of antimicrobial resistance, in any population, is closely correlated with the antimicrobial 'consumption' within that population. As the veterinary profession explores ways of addressing the emergence and selection of antimicrobial-resistant bacteria in food-producing animals, there is a need for veterinarians and producers to carefully consider all areas of antimicrobial use, and employ an evidence-based approach in designing appropriate clinical protocols. This paper aims to review current knowledge regarding the risk factors related to abdominal SSI in periparturient cows, and to encourage practitioners to judiciously evaluate both their standard operating procedures and their use of antimicrobials in these situations. In a second paper, to be published in a subsequent issue of Veterinary Record, these principles will be used to provide specific evidence-based recommendations for antimicrobial use in bovine abdominal surgery.

Neonatal-perinatal medicine fellow procedural experience and competency determination: results of a national survey.

OBJECTIVE: Ensuring that neonatal-perinatal medicine (NPM) fellows attain competency in performing neonatal procedures is a requirement of training-competent neonatologists. STUDY DESIGN: A survey of NPM fellows was performed to determine the procedural experience of current fellows, investigate techniques used to track procedural experience and examine the methods programs use to verify procedural competency. RESULTS: One hundred and sixty-three fellows in 57 accredited training programs responded to the survey. Reported number of procedures provide contemporary normative data on procedural experience during training. The majority of fellows reported using an online reporting system to track experience. The most common technique to verify procedural competency was supervised practice until an arbitrary number of procedures had been performed. CONCLUSIONS: NPM fellow procedural experience increases significantly for most, but not all, procedures duration training. We speculate that supplemental simulation training for rare neonatal procedures would help ensure the competency of graduating NPM fellows. Experience alone is insufficient to verify competency. Further work on the accurate tracking of experience and verification of procedural competency is needed.

Effect of flip-flops on lower limb kinematics during walking: a cross-sectional study using three-dimensional gait analysis.

BACKGROUND: Flip-flops are a popular footwear choice in warm weather however their minimalist design offers little support to the foot. AIM: To investigate the effect of flip-flops on lower limb gait kinematics in healthy adults, to measure adherence between the flip-flop and foot, and to assess the effect on toe clearance in swing. METHODS: Fifteen healthy adults (8 male, mean age 27 years) completed a three-dimensional gait analysis assessment using Codamotion. Kinematic and lower limb temporal-spatial data were captured using the Modified Helen Hayes marker set with additional markers on the hallux and flip-flop sole. RESULTS: Compared to barefoot walking, there were no differences in temporal-spatial parameters walking with flip-flops. There was an increase in peak knee flexion in swing (mean difference 4.6°, 95 % confidence interval (CI) [-5.8°, -3.4°], p < 0.001) and peak ankle dorsiflexion at terminal swing (mean difference 2°, 95 % CI [-3°, -1°], p = 0.001). Other kinematic parameters were unchanged. Peak separation between foot and flip-flop was 8.8 cm (SD 1.48), occurring at pre-swing. Minimum toe clearance of the hallux in barefoot walking measured 4.2 cm (SD 0.8). Minimum clearance of the flip-flop was 1.6 cm (SD 0.56). CONCLUSIONS: Healthy adults adapted well to flip-flops. However, separation of the flip-flop from the foot led to increased knee flexion and ankle dorsiflexion in swing, probably to ensure that the flip-flop did not contact the ground and to maximise adherence to the foot. Minimum clearance of the flip-flop was low compared to barefoot clearance. This may increase the risk of tripping over uneven ground.

Prevalence and burden of osteoarthritis amongst older people in Ireland: findings from The Irish LongituDinal Study on Ageing (TILDA).

OBJECTIVE: To investigate the prevalence of osteoarthritis (OA) in a population aged ≥50 years in Ireland, and to determine its relationship with demographic and health-related variables. METHODS: Cross-sectional data from Wave 1 of The Irish Longitudinal Study on Ageing (TILDA), a population-based study of 8175 people aged ≥50 years were analyzed. Logistic regression was used to determine associations between the presence of OA and a range of demographic and health-related variables. RESULTS: A total of 8175 people ≥50 years in Ireland were identified from the TILDA database of whom 45.7% (n = 2941) were male and 54.3% (n = 4431) were female. The overall prevalence of OA was 12.9% (women-17.3%; men-9.4%). Prevalence increased with age, with prevalence in those aged ≥ 80 years twice that [17.7%; 95% confidence interval (CI) 13.97, 21.54] of those aged 50-60 years (8.23, 95% CI 7.32, 9.13). On multivariable analysis, OA was significantly associated (P < 0.02) with female gender, older age, pain severity, higher body mass index (BMI), fear of falling, greater number of physical limitations and medication use. In particular, there was a strong association between the use of NSAIDS and the presence of OA [adj odd ratio (OR) = 5.88, 95% CI 4.16, 8.31]. A significant association was also found between OA and increasing number of chronic diseases (adj OR = 2.75 9, 95% CI = 2.44, 3.09). CONCLUSIONS: OA is a common and multifaceted condition, with comparable prevalence of self-reported OA in Ireland with similar populations. Assessment and management should focus on potentially modifiable factors such as BMI, pain, physical limitations, polypharmacy and fear of falling. More research is required to understand the complex inter-relationships between these and other risk-associated variables.

Development and validation of a feline abdominal palpation model and scoring rubric.

Simulation in veterinary education enables clinical skills practice without animal use. A feline abdominal palpation model was created that allows practice in this fractious species. This study assessed the model and rubric using a validation framework of content evidence, internal structure and relationship with level of training. Content Evidence: Veterinarians accepted this model as a helpful training tool for students (median=4 on five-point Likert scale). Internal Structure Evidence: G-coefficients were low for first- and second-year students (0.28 and 0.23), but were acceptable for veterinarians (0.61). Internal consistency values (0.24, 0.42 and 0.67) followed a similar pattern. Thus, scores were more reliable for veterinarians than for the students. Evidence of Relationship with Level of Training: Although level of training impacted reliability, its effect on performance scores was inconsistent. Analysis of variance (ANOVA) identified no differences among the groups of students and veterinarians. However, effect size between first- and third-year students was medium to large (0.62). Effect sizes between the veterinarians and student groups were small. Although the model and rubric appeared valid for experts, modifications would be necessary to generate reliable scores for students. These results allow greater understanding of the needs of students utilising a low-fidelity model.

Treatment of congenital pulmonary lymphangiectasia using ethiodized oil lymphangiography.

Historically, congenital pulmonary lymphangiectasia (CPL) has had poor treatment outcomes despite aggressive therapy. There are recent reports of ethiodized oil (Lipiodol) lymphangiography successfully treating lymphatic leakage in adults. In this report, we describe two infants with CPL complicated by chylothoraces successfully treated by instillation of ethiodized oil into the lymphatic system. Congenital atresia of the thoracic duct was demonstrated on the lymphangiogram in both patients before treatment. Both patients have shown good short-term outcomes without supplemental oxygen or fat restricted diets at 9 months of age. Ethiodized oil lymphangiography represents a new treatment modality for some patients with CPL.

Manual therapy for osteoarthritis of the hip or knee - a systematic review.

The aim of this systematic review was to determine if manual therapy improves pain and/or physical function in people with hip or knee OA. Eight databases were searched for randomised controlled trials (RCTs). Data were extracted and risk of bias assessed by independent reviewers. Four RCTs were eligible for inclusion (280 subjects), three of which studied people with knee OA and one studied those with hip OA. One study compared manual therapy to no treatment, one compared to placebo intervention, whilst two compared to alternative interventions. Meta-analysis was not possible due to clinical heterogeneity of the studies. One study had a low risk of bias and three had high risk of bias. All studies reported short-term effects, and long-term effects were measured in one study. There is silver level evidence that manual therapy is more effective than exercise for those with hip OA in the short and long-term. Due to the small number of RCTs and patients, this evidence could be considered to be inconclusive regarding the benefit of manual therapy on pain and function for knee or hip OA.

The Emotional Well-Being of the Nurse within the Multi-Skill Setting

The emotional well-being of nurses working in a multi-skill setting may be negatively influenced by their challenging work environment. A qualitative; explorative; descriptive and contextual study was conducted to investigate this phenomenon. The purpose of this study was to explore and describe the experience; as well as perceptions of coping mechanisms; of nurses working in the multi-skill setting; and to formulate recommendations to promote their emotional well-being. The population consisted of nurses working in a multi-skill setting (a Level-2 hospital) and included professional nurses; enrolled nurses and nurse assistants. An all-inclusive sample was used. Semi-structured interviews were conducted with three professional nurses; six enrolled nurses and one nurse assistant. These interviews were analysed according to the method described by Creswell (2003:192). The findings indicated that nurses have positive as well as negative experiences of the multi-skill setup. They cope by means of prioritising tasks; faith; self-motivation and mutual support. They also made suggestions for the promotion of their emotional well-being; on personal as well as managerial levels. Recommendations for further research; nurse education and practice were formulated. Recommendations for practice include 'on-the-spot' in-service training; appropriate task allocation; clearly defined scope of practice; time for rest and debriefing; strengthened relationships with management; promotion of strengths and creating a support system

Measuring patient satisfaction with exercise therapy for knee osteoarthritis: evaluating the utility of the physiotherapy outpatient survey.

OBJECTIVES: To assess patient satisfaction with exercise for knee osteoarthritis (OA). METHODS: A convenience sample of 27 patients recruited to a randomized controlled trial (RCT) comparing open kinetic chain and closed kinetic chain exercises for knee OA were reassessed at nine months post-randomization. Clinical outcomes included self-report and physical performance measures of function and pain severity. Patients also completed the Physiotherapy Outpatient Survey (POPS), which is a multi-dimensional measure of patient satisfaction with physiotherapy. RESULTS: There was no significant difference in satisfaction between the two intervention groups. Overall mean satisfaction for the entire cohort was 4.07 of a maximum score of 5 (standard deviation (SD) = 0.52). Lower levels of satisfaction with outcome (mean = 3.56, SD = 0.8) were reported compared with other domains of expectations, communication, organization and the therapist (mean = 3.79-4.49; SDs = 0.42-0.92). Both intervention groups improved from baseline on clinical outcomes of pain, self-report function and walking distance, with no significant differences between the two groups. CONCLUSIONS: High levels of satisfaction were reported in this subsample of knee OA patients participating in an RCT evaluating the effects of different exercise approaches for knee OA. Satisfaction varied depending on the satisfaction domain, with lower satisfaction with outcome compared with other aspects of care. The POPS questionnaire can be used to measure the multi-dimensional aspects of satisfaction with physiotherapy.
