How do UK physiotherapists address weight loss among individuals with hip osteoarthritis? A mixed-methods study

Feasibility of conducting a cohort randomized controlled trial assessing the effectiveness of a nurse-led package of care for knee pain

OBJECTIVE

To evaluate the feasibility of conducting a cohort randomized controlled trial (RCT) of a nurse-led package of care for knee pain and determining a treatment sequence for use in a future trial.

METHODS

This study was an open-label, three-arm, single-centre, mixed-methods, feasibility cohort RCT. Adults aged ≥40 years with moderate-to-severe knee pain for ≥3 months were eligible. Participants were randomized into group A (non-pharmacological treatment first), group B (pharmacological treatment first), or group C (usual care). The intervention was delivered over 26 weeks. Outcomes were dropout rate, recruitment rate, intervention fidelity, ability to collect outcome data, and treatment acceptability.

RESULTS

Seventeen participants were randomized and enrolled into each of groups A and B (5.2% recruitment rate), and 174 participants were randomized to group C. The participant characteristics at randomization were comparable across the three arms. Coronavirus disease (COVID-19) paused the study from March-November 2020. Participants enrolled in groups A and B before March 2020 were withdrawn at the restart. Of the 20 participants enrolled after the restart, 18 completed the study (10% dropout). The nurse reported delivering most aspects of the intervention with high fidelity. The participants viewed the package of care as structured, supportive and holistic, they learnt about self-managing knee pain, and they could engage with and follow the non-pharmacological treatment. Most found the non-pharmacological treatment more useful than the pharmacological treatment, preferring to receive it before or alongside analgesia. Many self-report questionnaires were not fully completed.

CONCLUSION

The nurse-led package of care for knee pain was acceptable, with low dropout, although the cohort RCT design may not be feasible for a definitive trial.

Co-development and testing of an extended community pharmacy model of service delivery for managing osteoarthritis: protocol for a sequential, multi-methods study (PharmOA)

BACKGROUND

Osteoarthritis is a common, painful and disabling long-term condition. Delivery of high-quality guideline-informed osteoarthritis care that successfully promotes and maintains supported self-management is imperative. However, osteoarthritis care remains inconsistent, including under use of core non-pharmacological approaches of education, exercise and weight loss. Community pharmacies are an accessible healthcare provider. United Kingdom government initiatives are promoting their involvement in a range of long-term conditions, including musculoskeletal conditions. It is not known what an enhanced community pharmacy role for osteoarthritis care should include, what support is needed to deliver such a role, and whether it would be feasible and acceptable to community pharmacy teams. In this (PharmOA) study, we aim to address these gaps, and co-design and test an evidence-based extended community pharmacy model of service delivery for managing osteoarthritis.

METHODS

Informed by the Theoretical Domains Framework, Normalisation Process Theory, and the Medical Research Council (MRC) framework for developing complex interventions, we will undertake a multi-methods study involving five phases: 1. Systematic review to summarise currently available evidence on community pharmacy roles in supporting adults with osteoarthritis and other chronic (non-cancer) pain. 2. Cross-sectional surveys and one-to-one qualitative interviews with patients, healthcare professionals and pharmacy staff to explore experiences of current, and potential extended community pharmacy roles, in delivering osteoarthritis care. 3. Stakeholder co-design to: a) agree on the extended role of community pharmacies in osteoarthritis care; b) develop a model of osteoarthritis care within which the extended roles could be delivered (PharmOA model of service delivery); and c) refine existing tools to support community pharmacies to deliver extended osteoarthritis care roles (PharmOA tools). 4. Feasibility study to explore the acceptability and feasibility of the PharmOA model of service delivery and PharmOA tools to community pharmacy teams. 5. Final stakeholder workshop to: a) finalise the PharmOA model of service delivery and PharmOA tools, and b) if applicable, prioritise recommendations for its wider future implementation.

DISCUSSION

This novel study paves the way to improving access to and availability of high-quality guideline-informed, consistent care for people with osteoarthritis from within community pharmacies.

Clinical reasoning in managing chronic hip pain: One in two Australian and New Zealand physiotherapists diagnosed a case vignette with clinical criteria for hip OA as hip OA. A cross-sectional survey

OBJECTIVES

Using a case vignette of an adult (George) presenting with hip pain consistent with hip OA, this study aimed to describe: (a) whether physiotherapists make diagnoses and identify bodily structures using either patient history and/or physical examination findings; (b) which diagnoses and bodily structures physiotherapists attribute to the hip pain; (c) how confident physiotherapists were in their clinical reasoning using patient history and physical examination findings; (d) what treatments physiotherapists would offer to George.

METHODS

We conducted a cross-sectional online survey of physiotherapists in Australia and New Zealand. We used descriptive statistics to analyse closed questions and content analysis for open-text responses.

RESULTS

Two hundred and twenty physiotherapists completed the survey (39% response-rate). After receiving the patient history, 64% diagnosed George's pain and 49% of these as hip OA; 95% attributed George's pain to a bodily structure(s). After receiving the physical examination, 81% diagnosed George's hip pain and 52% of these as hip OA; 96% attributed George's hip pain to a bodily structure(s). Ninety-six percent of respondents were at least somewhat confident in their diagnosis after the patient history, and 95% were similarly confident after the physical examination. Most respondents offered advice (98%) and exercise (99%), but fewer offered treatments for weight loss (31%), medication (11%), and psychosocial factors (<15%).

DISCUSSION

About half of the physiotherapists that diagnosed George's hip pain made a diagnosis of hip OA, despite the case vignette including clinical criteria for a diagnosis of OA. Physiotherapists offered exercise and education, but many physiotherapists did not offer other clinically indicated and recommended treatments, such as weight loss and sleep advice.

Physiotherapy for patients with hip and knee osteoarthritis in Germany: a survey of current practice

BACKGROUND

Osteoarthritis (OA) of the hip and the knee is common and leads to pain, stiffness and disability. Clinical practice guidelines (CPG) provide recommendations to assist healthcare professionals in clinical decision-making. Although evidence-based physiotherapy has been shown to be effective in the management OA, a gap between clinical practice and guideline recommendations exists. Little is known about OA management provided by physiotherapists in Germany and whether treatment aligns with CPGs. The objectives of this study were (1) to investigate the current physiotherapy practice in patients with hip and/or knee OA in Germany, (2) to evaluate physiotherapists' adherence to guideline recommendations and (3) to explore barriers and facilitators to guideline use.

METHODS

A cross-sectional online survey was conducted among physiotherapists. The questionnaire collected information on demographic characteristics, physiotherapists' management of hip and knee OA and the use of CPGs in clinical practice. Guideline adherence was evaluated by comparing the survey findings with guideline recommendations. Full adherence was assumed if all recommended treatment options were chosen.

RESULTS

In total, 447 (74.9%) of 597 eligible physiotherapists completed the survey. Data from 442 participants (mean age 41.2 ± 12.8 years; 288 female (65.1%)) were included in the analysis. The most common treatment choices for both hip and knee OA were exercise therapy (hip OA: 424/442, 95.9%; knee OA: 426/442, 96.4%), self-management advice (hip OA: 413/442, 93.2%; knee OA: 395/442, 89.4%) and education (hip OA: 325/442, 73.5%; knee OA: 331/442, 74.9%), followed by manual therapy (hip OA: 311/442, 70.4%; knee OA: 311/442, 70.4%) and joint traction (hip OA: 208/442, 47.1%; knee OA: 199/442, 45.0%). Full guideline adherence was found in 17.2% (76/442) of physiotherapists for hip OA management and in 8.6% (38/442) for knee OA. Less than half of the respondents (212/430, 49.3%) were aware of an OA guideline.

CONCLUSIONS

In accordance with current guideline recommendations, most physiotherapists provide exercise therapy and education for patients with hip and/or knee OA. Interventions with low or conflicting evidence were also frequently provided. The limited awareness of existing OA guidelines and the low guideline adherence indicate an insufficient implementation of CPGs in German physiotherapy practice.

Factors That Patients Consider in Their Choice of Non-Surgical Management for Hip and Knee Osteoarthritis: Formative Qualitative Research for a Discrete Choice Experiment

BACKGROUND

Approximately half of patients with hip and knee osteoarthritis have tried non-surgical management before surgical consultation. Understanding the many factors affecting the uptake of recommended strategies is important to inform future development of such management strategies.

OBJECTIVES

The aim of this study was to explore and identify factors that patients with osteoarthritis consider when choosing non-surgical management for hip and knee osteoarthritis, as formative research for a study of patient preferences for non-surgical management programs for osteoarthritis.

METHODS

A qualitative research design was used. Participants were recruited using a combination of stratified and convenience sampling. Interviews were conducted, using a semi-structured interview guide, with English-speaking patients who had self-reported hip and/or knee osteoarthritis and at least one joint that had not undergone replacement surgery. Data were thematically analyzed.

RESULTS

Thirteen patients participated in these interviews. Sixteen factors that participants considered when choosing non-surgical osteoarthritis management were identified. Eleven were extrinsic, relating to features of programs and services, and are categorized as types of interventions, general program and service details, and program-specific details. Five were intrinsic to the individual and influenced how decisions for osteoarthritis management were approached and the options available to choose from. Three novel factors included participants' desire for further management, their views about joint replacement surgery, and whether they felt personal choice was available in osteoarthritis management strategies.

CONCLUSION

Key factors were identified that patients considered when making decisions about non-surgical management for their osteoarthritis that will be used to inform a discrete choice experiment (DCE) that aims to measure preferences for these factors.

Patient and practitioner priorities and concerns about primary healthcare interactions for osteoarthritis: A meta-ethnography

OBJECTIVE

To explore primary care practitioners' (PCPs) and patients' priorities and concerns for healthcare interactions for osteoarthritis (OA) in primary care.

METHODS

We searched Embase, CINAHL, Medline, PsychInfo (1990 to present) for primary qualitative and mixed methods studies with findings concerning healthcare interactions for OA symptoms. Patient and PCP perceptions were analysed separately then inter-related using a 'line of argument' synthesis.

RESULTS

Twenty-six studies reporting qualitative data from 557 patients and 199 PCPs were synthesised. Our findings suggest that therapeutic interactions for OA can be based on discordant priorities and concerns; some patients perceive that PCPs hold negative attitudes about OA and feel their concerns about impact are not appreciated; some PCPs feel patients have misconceptions about prognosis, and hold pessimistic views about outcomes; and both tend to de-prioritise OA within consultations.

CONCLUSION

Greater working in partnership could build mutual trust, facilitate tailored provision of information, and foster a shared understanding of OA upon which to build realistic goals for management.

PRACTICE IMPLICATIONS

Developing a better shared understanding of OA has the potential to improve the quality of healthcare interactions for both patients and PCPs. The significant impact of OA on everyday life means it should be given higher priority in primary care consultations.

Mind the Gap: Exploring Nutritional Health Compared With Weight Management Interests of Individuals with Osteoarthritis

Background

For persons with osteoarthritis (OA), nutrition education may facilitate weight and OA symptom management.

Objectives

The primary aim of this study was to determine preferred OA-related nutritional and weight management topics and their preferred delivery modality. The secondary aim was to determine whether there is a disconnect between what patients want to know about nutrition and OA management and what information health-care professionals (HCPs) are providing to patients.

Methods

The Osteoarthritis Action Alliance surveyed individuals with OA to identify their preferences, categorized in 4 domains: 1) strategies for weight management and a healthy lifestyle; 2) vitamins, minerals, and other supplements; 3) foods or nutrients that may reduce inflammation; and 4) diets for weight loss. HCPs were provided these domains and asked which topics they discussed with patients with OA. Both groups were asked to select currently utilized or preferred formats of nutritional resources.

Results

Survey responses from 338 individuals with OA and 104 HCPs were included. The highest preference rankings in each domain were: 1) foods that make OA symptoms worse (65%), foods and nutrients to reduce inflammation (57%), and healthy weight loss (42%); 2) glucosamine (53%), vitamin D (49%), and omega-3 fatty acids (45%); 3) spices and herbs (65%), fruits and vegetables (58%), and nuts (40%); and 4) Mediterranean diet (21%), low-carbohydrate diet (18%), and fasting or intermittent fasting (15%). There was greater than 20% discrepancy between interests reported by individuals with OA and discussions reported by HCPs on: weight loss strategies, general information on vitamins and minerals, special dietary considerations for other conditions, mindful eating, controlling caloric intake or portion sizes, and what foods worsen OA symptoms. Most respondents preferred to receive nutrition information in a passive format and did not want information from social media messaging.

Conclusions

There is disparity between the nutrition education content preferred by individuals with OA (which often lacks empirical support) and evidence-based topics being discussed by HCPs. HCPs must communicate evidence-based management of joint health and OA symptoms in patient-preferred formats. This study explored the information gap between what individuals with OA want to know and what HCPs believe they need to know.

Effects of an Online Education Program on Physical Therapists' Confidence in Weight Management for People With Osteoarthritis: A Randomized Controlled Trial

OBJECTIVE

To evaluate effects of an online education program about weight management for osteoarthritis on physical therapists' self-reported confidence in knowledge and skills in weight management and attitudes toward obesity.

METHODS

In a 2-group randomized controlled trial, 80 physical therapists (58 female physical therapists) were randomized to education or control groups. The theoretically informed and evidence-informed online self-directed training program covered biopsychosocial elements of obesity and weight management. The primary outcome was self-reported confidence in knowledge in weight management using a customized validated tool (scale 14-70, higher scores indicating higher confidence) assessed at baseline and 6 weeks. Secondary measures included confidence in nutrition care, clinical skills in weight management, and weight stigma. Process measures evaluated participant experience. Differences in change between groups were compared using linear regression models adjusted for baseline scores and stratifying variables (clinical setting; confidence in weight management). Moderation analysis was performed using an interaction approach in a linear regression model and multivariable fractional polynomial interaction approach.

RESULTS

A total of 79 participants (99%) completed outcome measures at 6 weeks. The education group demonstrated greater improvement in confidence in knowledge than the control group (adjusted mean difference 22.6 units, 95% confidence interval 19.6, 25.5). Greater improvement in knowledge was associated with lower baseline values (interaction P = 0.002). Secondary outcomes showed greater improvements in confidence in skills and nutrition care and in weight stigma domains favoring the education group. Over 90% of participants would recommend the program to peers.

CONCLUSION

An online education program improves physical therapists' short-term confidence in knowledge and skills in weight management for people with osteoarthritis and reduces weight-stigmatized attitudes.

Experience of the COVID-19 pandemic as lived by patients with hip and knee osteoarthritis: an Italian qualitative study

OBJECTIVE

To examine the experience of the COVID-19 pandemic as lived by people with hip and knee osteoarthritis (OA), in Italy.

DESIGN

A qualitative study based on semi-structured interviews.

SETTING

Urban and suburban areas in northern Italy.

PARTICIPANTS

A total of 11 people with OA were enrolled through a purposeful sampling and completed the study.

PRIMARY OUTCOME MEASURE

The experience of Italian people with OA during the COVID-19 pandemic.

RESULTS

Four themes were brought to the forefront from the analysis of the interviews. (1) Being Stressed for the Limited Social Interactions and for the Family Members at High Risk of Infection, as the interviewees were frustrated because they could not see their loved ones or felt a sense of apprehension for their relatives. (2) Recurring Strategies to Cope with the Pandemic such as an active acceptance towards the situation. (3) Being Limited in the Possibility of Undergoing OA Complementary Treatments and Other Routine Medical Visits. (4) Being Unaware of the Importance of Physical Activity as First-Line Interventions which was an attitude already present before the pandemic.

CONCLUSION

The COVID-19 pandemic and related restrictions impacted the quality of life and the care of individuals with hip and knee OA. The social sphere seemed to be the most hindered. However, the interviewees developed a good level of acceptance to deal with the pandemic. When it came to their care, they faced a delay of routine medical visits not related to OA and of other complementary treatments (eg, physical therapies) to manage OA. Finally, a controversial result that emerged from these interviews was that first-line interventions for OA (ie, therapeutic exercise) was not sought by the interviewees, regardless of the restrictions dictated by the pandemic. Policy-making strategies are thus necessary to support the awareness of the importance of such interventions.

Italian physiotherapists' knowledge of and adherence to osteoarthritis clinical practice guidelines: a cross-sectional study

INTRODUCTION

Implementation of clinical practice guidelines (CPGs) to manage musculoskeletal conditions among physiotherapists appears suboptimal. Osteoarthritis is one of the most disabling conditions worldwide and several studies showed a lack of knowledge of and adherence to osteoarthritis CPGs in physiotherapists' clinical practice. However, those studies are not conclusive, as they examine the knowledge of and adherence to CPGs only in isolation, or only by focussing on a single treatment. Thus, analysis of the knowledge of and adherence to CPGs in the same sample would allow for a better understanding of the evidence-to-practice gap, which, if unaddressed, can lead to suboptimal care for these patients. This study aims at assessing Italian physiotherapists' evidence-to-practice gap in osteoarthritis CPGs.

METHODS

An online survey divided into two sections investigating knowledge of and adherence to CPGs was developed based on three high-quality, recent and relevant CPGs. In the first section, participants had to express their agreement with 24 CPG statements through a 1 (completely disagree) to 5 (completely agree) scale. We defined a ≥ 70% agreement with a statement as consensus. In the second section, participants were shown a clinical case, with different interventions to choose from. Participants were classified as 'Delivering' (all recommended interventions selected), 'Partially Delivering' (some recommended interventions missing) and 'Non-Delivering' (at least one non-recommended interventions selected) the recommended intervention, depending on chosen interventions.

RESULTS

822 physiotherapists (mean age (SD): 35.8 (13.3); female 47%) completed the survey between June and July 2020. In the first section, consensus was achieved for 13/24 statements. In the second section, 25% of the participants were classified as 'Delivering', 22% as 'Partially Delivering' and 53% as 'Non-Delivering'.

CONCLUSIONS

Our findings revealed an adequate level of knowledge of osteoarthritis CPGs regarding the importance of exercise and education. However, an adequate level of adherence has yet to be reached, since many physiotherapists did not advise weight reduction, but rest from physical activity, and often included secondary treatments (e.g. manual therapy) supported by low-level evidence. These results identify an evidence-to-practice gap, which may lead to non-evidence based practice behaviours for the management of patients with osteoarthritis.

Improving osteoarthritis management in primary healthcare: results from a quasi-experimental study

Background

To improve quality of care for patients with hip and knee osteoarthritis (OA), general practitioners (GPs) and physiotherapists (PTs) in a Norwegian municipality initiated an intervention. The intervention aimed to increase provision of core OA treatment (information, exercise, and weight control) prior to referral for surgery, rational use of imaging for assessing OA and improve communication between healthcare professionals. This study assessed the effectiveness of this intervention.

Methods

Forty-eight PTs and one hundred one GPs were invited to the intervention that included two interactive workshops outlining best practice and an accompanying template for PT discharge reports. Using interrupted time series research design, the study period was divided into three: pre-implementation, transition (implementation) and post-implementation. Comparing the change between pre- and post-implementation, the primary outcome was patient-reported quality of OA care measured with the OsteoArthritis Quality Indicator questionnaire. Secondary outcomes were number of PT discharge reports, information included in GP referral letters to orthopaedic surgeon, the proportion of GP referral letters indicating use of core treatment, and the use of imaging within OA assessment. Analyses involved linear mixed and logistic regression models.

Results

The PT workshop had 30 attendees, and 31 PTs and 33 GPs attended the multidisciplinary workshop. Two hundred eight and one hundred twenty-five patients completed the questionnaire during pre- and post-implementation, respectively. The adjusted model showed a small, statistically non-significant, increase in mean total score for quality of OA care (mean change = 4.96, 95% CI -0.18, 10.12, p:0.057), which was mainly related to items on OA core treatment. Patients had higher odds of reporting receipt of information on treatment alternatives (odds ratio (OR) 1.9, 95% CI 1.08, 3.24) and on self-management (OR 2.4, 95% CI 1.33, 4.32) in the post-implementation phase. There was a small, statistically non-significant, increase in the proportion of GP referral letters indicating prior use of core treatment modalities. There were negligible changes in the number of PT discharge reports, in the information included in the GP referral letters, and in the use of imaging for OA assessment.

Conclusion

This study suggests that a primary care intervention including two inter-active workshops can shift the quality of care towards best practice recommendations.

Do comorbidities predict pain and function in knee osteoarthritis following an exercise intervention, and do they moderate the effect of exercise? Analyses of data from three randomized controlled trials

BACKGROUND

Although exercise is a core treatment for people with knee osteoarthritis (OA), it is currently unknown whether those with additional comorbidities respond differently to exercise than those without. We explored whether comorbidities predict pain and function following an exercise intervention in people with knee OA, and whether they moderate response to: exercise versus no exercise; and enhanced exercise versus usual exercise-based care.

METHODS

We undertook analyses of existing data from three randomized controlled trials (RCTs): TOPIK (n = 217), APEX (n = 352) and Benefits of Effective Exercise for knee Pain (BEEP) (n = 514). All three RCTs included: adults with knee pain attributable to OA; physiotherapy-led exercise; data on six comorbidities (overweight/obesity, pain elsewhere, anxiety/depression, cardiac problems, diabetes mellitus and respiratory conditions); the outcomes of interest (six-month Western Ontario and McMaster Universities Arthritis Index knee pain and function). Adjusted mixed models were fitted where data was available; otherwise linear regression models were used.

RESULTS

Obesity compared with underweight/normal body mass index was significantly associated with knee pain following exercise, as was the presence compared with absence of anxiety/depression. The presence of cardiac problems was significantly associated with the effect of enhanced versus usual exercise-based care for knee function, indicating that enhanced exercise may be less effective for improving knee function in people with cardiac problems. Associations for all other potential prognostic factors and moderators were weak and not statistically significant.

CONCLUSIONS

Obesity and anxiety/depression predicted pain and function outcomes in people offered an exercise intervention, but only the presence of cardiac problems might moderate the effect of exercise for knee OA. Further confirmatory investigations are required.
