Incremental clinical effectiveness and cost effectiveness of providing supervised physiotherapy in addition to usual medical care in patients with osteoarthritis of the hip or knee: 2-year results of the MOA randomised controlled trial

Orthopaedic Manual Physical Therapy: A Modern Definition and Description

Currently, orthopaedic manual physical therapy (OMPT) lacks a description of practice that reflects contemporary thinking and embraces advances across the scientific, clinical, and educational arms of the profession. The absence of a clear definition of OMPT reduces understanding of the approach across health care professions and potentially limits OMPT from inclusion in scientific reviews and clinical practice guidelines. For example, it is often incorrectly classified as passive care or incorrectly contrasted with exercise-therapy approaches. This perspective aims to provide clinicians, researchers, and stakeholders a modern definition of OMPT that improves the understanding of this approach both inside and outside the physical therapist profession. The authors also aim to outline the unique and essential aspects of advanced OMPT training with the corresponding examination and treatment competencies. This definition of practice and illustration of its defining characteristics is necessary to improve the understanding of this approach and to help classify it correctly for study in the scientific literature. This perspective provides a current definition and conceptual model of OMPT, defining the distinguishing characteristics and key elements of this systematic and active patient-centered approach to improve understanding and help classify it correctly for study in the scientific literature.

Progressive Resistance Training or Neuromuscular Exercise for Hip Osteoarthritis : A Multicenter Cluster Randomized Controlled Trial

BACKGROUND

Exercise is recommended as first-line treatment for patients with hip osteoarthritis (OA). However, randomized controlled trials providing evidence for the optimal exercise type are lacking.

OBJECTIVE

To investigate whether progressive resistance training (PRT) is superior to neuromuscular exercise (NEMEX) for improving functional performance in patients with hip OA.

DESIGN

Multicenter, cluster-randomized, controlled, parallel-group, assessor-blinded, superiority trial. (ClinicalTrials.gov: NCT04714047).

SETTING

Hospitals and physiotherapy clinics.

PARTICIPANTS

160 participants with clinically diagnosed hip OA were enrolled from 18 January 2021 to 28 April 2023 and randomly assigned to PRT (n = 82) or NEMEX (n = 78).

INTERVENTION

Twelve weeks of PRT or NEMEX with 2 supervised 60-minute group sessions each week. The PRT intervention consisted of 5 high-intensity resistance training exercises targeting muscles at the hip and knee joints. The NEMEX intervention included 10 exercises and emphasized sensorimotor control and functional stability.

MEASUREMENTS

The primary outcome was change in the 30-second chair stand test (30s-CST). Key secondary outcomes were changes in scores on the pain and hip-related quality of life (QoL) subscales of the Hip Disability and Osteoarthritis Outcome Score (HOOS).

RESULTS

The mean changes from baseline to 12-week follow-up in the 30s-CST were 1.5 (95% CI, 0.9 to 2.1) chair stands with PRT and 1.5 (CI, 0.9 to 2.1) chair stands with NEMEX (difference, 0.0 [CI, -0.8 to 0.8] chair stands). For the HOOS pain subscale, mean changes were 8.6 (CI, 5.3 to 11.8) points with PRT and 9.3 (CI, 5.9 to 12.6) points with NEMEX (difference, -0.7 [CI, -5.3 to 4.0] points). For the HOOS QoL subscale, mean changes were 8.0 (CI, 4.3 to 11.7) points with PRT and 5.7 (CI, 1.9 to 9.5) points with NEMEX (difference, 2.3 [CI, -3.0 to 7.6] points).

LIMITATION

Participants and physiotherapists were not blinded.

CONCLUSION

In patients with hip OA, PRT is not superior to NEMEX for improving functional performance, hip pain, or hip-related QoL.

What are participant beliefs regarding physical therapy led treatment? A qualitative study of people living with femoroacetabular impingement syndrome

BACKGROUND

Physical therapist-led treatment programs are recommended for patients with femoroacetabular impingement (FAI) syndrome. Views of people with FAI syndrome regarding such interventions are currently unknown, including perceptions of potential barriers and facilitators to participation and adherence to exercise programs.

OBJECTIVES

To explore participant perceptions of physical therapist-led programs for FAI syndrome, including barriers and facilitators for accessing physical therapy, and adhering to a rehabilitation program.

METHODS

Our qualitative study used semi-structured interviews to explore the perceptions of patients with FAI syndrome undertaking physical therapy-led treatment, where treatment was ceased due to Coronavirus Disease 2019 (COVID-19). The interview topic guide was informed by the Theoretical Domain Framework. Interviews were transcribed verbatim and data categories were developed using inductive thematic analysis. Themes were discussed between researchers until consensus was reached.

RESULTS

Fourteen participants (mean age: 30 years) with a range of physical activity backgrounds undertook interviews. We identified four key themes, 1) Patients believed their hip pain was caused by structural damage worsened through exercise; 2) Barriers and facilitators on the feasibility of physical therapist-led programs; 3) Participants held beliefs regarding the importance of adjunct treatments to exercise; and 4) Impact of FAI syndrome on physical activity participation.

CONCLUSION

People with FAI syndrome believe they have structural damage which leads to their hip pain and are often afraid to exercise due to fear of causing more damage to their hip. Our findings suggest that people with FAI syndrome want clear education about exercise, imaging, and expectations of cost and duration of treatment.

Cost-Effectiveness of Treatments for Musculoskeletal Conditions Offered by Physiotherapists: A Systematic Review of Trial-Based Evaluations

BACKGROUND

Musculoskeletal conditions are a leading contributor to disability worldwide. The treatment of these conditions accounts for 7% of health care costs in Germany and is often provided by physiotherapists. Yet, an overview of the cost-effectiveness of treatments for musculoskeletal conditions offered by physiotherapists is missing. This review aims to provide an overview of full economic evaluations of interventions for musculoskeletal conditions offered by physiotherapists.

METHODS

We systematically searched for publications in Medline, EconLit, and NHS-EED. Title and abstracts, followed by full texts were screened independently by two authors. We included trial-based full economic evaluations of physiotherapeutic interventions for patients with musculoskeletal conditions and allowed any control group. We extracted participants' information, the setting, the intervention, and details on the economic analyses. We evaluated the quality of the included articles with the Consensus on Health Economic Criteria checklist.

RESULTS

We identified 5141 eligible publications and included 83 articles. The articles were based on 78 clinical trials. They addressed conditions of the spine (n = 39), the upper limb (n = 8), the lower limb (n = 30), and some other conditions (n = 6). The most investigated conditions were low back pain (n = 25) and knee and hip osteoarthritis (n = 16). The articles involved 69 comparisons between physiotherapeutic interventions (in which we defined primary interventions) and 81 comparisons in which only one intervention was offered by a physiotherapist. Physiotherapeutic interventions compared to those provided by other health professionals were cheaper and more effective in 43% (18/42) of the comparisons. Ten percent (4/42) of the interventions were dominated. The overall quality of the articles was high. However, the description of delivered interventions varied widely and often lacked details. This limited fair treatment comparisons.

CONCLUSIONS

High-quality evidence was found for physiotherapeutic interventions to be cost-effective, but the result depends on the patient group, intervention, and control arm. Treatments of knee and back conditions were primarily investigated, highlighting a need for physiotherapeutic cost-effectiveness analyses of less often investigated joints and conditions. The documentation of provided interventions needs improvement to enable clinicians and stakeholders to fairly compare interventions and ultimately adopt cost-effective treatments.

Difficulties Experienced by Patients with Knee Osteoarthritis during the Conservative Treatment Process: A Qualitative Study

BACKGROUND AND OBJECTIVES

This study aimed to investigate the difficulties faced by patients with knee osteoarthritis during the conservative treatment process.

MATERIALS AND METHODS

We included twenty-one patients who were diagnosed with knee osteoarthritis and admitted to the orthopedics and traumatology outpatient clinic of the hospital where the researcher worked between January 2022 and April 2022. We interviewed each patient using semi-structured face-to-face interviews. To analyze the interviews, the researcher used the directed content analysis method. Data were analyzed using the NVIVO 10 software package. The authors and the expert trained in qualitative research who generously supported the authors continued the analysis independently of each other until they reached a consensus.

RESULTS

After analysis of the interviews held with the participants, the following three main themes emerged: lack of information about conservative treatment, frequent change of physicians, and non-compliance with lifestyle changes. Two sub-themes were identified within the theme of frequent change of physicians: distrusting health personnel, and not being able to make an appointment. In addition, most of the patients were not knowledgeable enough about either the definition of the disease or the treatment process. These patients stated that they were confused because they had to change physicians frequently; thus, they distrusted physicians because each physician they visited made a different plan for the treatment process.

CONCLUSIONS

At the end of the study, we determined that during the conservative treatment process of patients with knee osteoarthritis, a multidisciplinary approach should be adopted, and orthopedic surgeons, physical therapy and rehabilitation physicians, dietitians, and physiotherapists should be in harmony with the patient. In addition, health personnel should provide patients with detailed information to eliminate questions they have during the conservative treatment process. In order for healthcare team members to establish a trusting relationship between the patients, they should allocate enough time to the patient.

Knee osteoarthritis patient perspectives of their care in an australian private physiotherapy setting: a qualitative exploratory interview study

PURPOSE

This study aimed to understand perceptions that knee osteoarthritis patients have regarding their experiences of guideline-based recommendations within their care received from physiotherapists in private practice.

METHODS

A qualitative semi-structured interview study nested within a larger trial auditing care provided by physiotherapists. Recruited adults ≥ 45 years with knee osteoarthritis across nine primary care physiotherapy practices. Interview questions were anchored around the core elements recommended in guidelines for the management of knee osteoarthritis and patient perceptions of these were analysed using both content and thematic qualitative analysis approaches. Patient satisfaction with care received was asked at the time of interview.

RESULTS

Twenty-six patients volunteered for the study (mean 60 years, 58% female). Analysis identified that physiotherapists focused on treating symptoms through quadriceps strengthening exercises, which patients found to be effective, though focussed less on other aspects of evidenced-based care. Patient's perceived treatment to be effective in relieving pain and enabling them to stay active and they appreciated the positive role that their physiotherapist provided in alleviating their concerns. Overall, patients were satisfied with their physiotherapy care but would have liked more specific osteoarthritis education and longer-term management.

CONCLUSION

The description of the physiotherapy-related care received by people with knee osteoarthritis aligns with guideline recommendations, though mainly for strength-related exercise prescription. Despite some perceived shortfalls in care, patients do appear to be satisfied. However, improvements in patient outcomes may be possible if more elements of guideline-base care are regularly provided, including enhancing osteoarthritis education and fostering behaviour change.

CycLing and EducATion (CLEAT): protocol for a single centre randomised controlled trial of a cycling and education intervention versus standard physiotherapy care for the treatment of hip osteoarthritis

BACKGROUND

Osteoarthritis (OA) is a chronic degenerative joint disorder for which there is no known cure. Non-surgical management for people with mild-to-moderate hip OA focuses mainly on alleviating pain and maximising function via the National Institute for Health and Care Excellence (NICE) recommended combination of education and advice, exercise, and, where appropriate, weight loss. The CHAIN (Cycling against Hip pAIN) intervention is a group cycling and education intervention conceived as a way of implementing the NICE guidance.

METHODS

CycLing and EducATion (CLEAT) is a pragmatic, two parallel arm, randomised controlled trial comparing CHAIN with standard physiotherapy care for the treatment of mild-to-moderate hip OA. We will recruit 256 participants referred to the local NHS physiotherapy department over a 24-month recruitment period. Participants diagnosed with hip OA according to NICE guidance and meeting the criteria for GP exercise referral will be eligible to participate. Primary outcome is the difference in Hip Disability and Osteoarthritis Outcome Score (HOOS) function, daily living subscale between those receiving CHAIN and standard physiotherapy care. Secondary outcomes include performance-based functional measures (40 m walking, 30s chair stand and stair climb tests), ability for patient to self-care (patient activation measure) and self-reported health-related resource use including primary and secondary care contacts. The primary economic endpoint is the number of quality adjusted life years (QALYs) at 24 weeks follow-up. The study is funded by the National Institute for Health Research, Research for Patient Benefit PB-PG-0816-20033.

DISCUSSION

The literature identifies a lack of high-quality trials which inform on the content and design of education and exercise in the treatment of patients with hip OA and explore cost-effectiveness. CLEAT is a pragmatic trial which seeks to build further evidence of the clinical benefits of the CHAIN intervention compared to standard physiotherapy care within a randomised, controlled trial setting, and examine its cost-effectiveness.

Researcher's Perspective on Musculoskeletal Conditions in Primary Care Physiotherapy Units through the International Classification of Functioning, Disability, and Health (ICF): A Scoping Review

(1) Background: Musculoskeletal disorders are the second cause of disability in the world. The International Classification of Functioning Disability and Health (ICF) is a tool for systematically describing functioning. Outcome measures for musculoskeletal disorders and functioning concepts embedded in them have not been described under the ICF paradigm. The objective of this scoping review was to identify ICF categories representing the researcher's perspective and to compare them with the ICF core set for post-acute musculoskeletal conditions. (2) Methods: This review was conducted as follows: (a) literature search using MEDLINE/PubMed, CINAHL, Web of Science, and Scopus databases; (b) study selection applying inclusion criteria (PICOS): musculoskeletal conditions in primary care, application of physiotherapy as a treatment, outcome measures related to functioning, and experimental or observational studies conducted in Western countries during the last 10 years; (c) extraction of relevant concepts; (d) linkage to the ICF; (e) frequency analysis; and (f) comparison with the ICF core set. (3) Results: From 540 studies identified, a total of 51 were included, and 108 outcome measures were extracted. In the ICF linking process, 147 ICF categories were identified. Analysis of data showed that 84.2% of the categories in the ICF core set for post-acute musculoskeletal conditions can be covered by the outcome measures analyzed. Sixty-eight relevant additional ICF categories were identified. (4) Conclusion: Outcome measures analyzed partially represent the ICF core set taken as a reference. The identification of additional categories calls into question the applicability of this core set in primary care physiotherapy units.

Activity-related pain predicts pain and functional outcomes in people with knee osteoarthritis: A longitudinal study

Knee Osteoarthritis (OA) is a prevalent musculoskeletal condition, commonly resulting in pain and disability. However, pain and disability in this population are poorly related with the degree of structural joint damage. Underlying pain mechanisms, including activity-related pain and sensitization assessed via Quantitative Sensory Testing (QST), may better predict pain and functional outcomes of those with knee OA. Therefore, the aim of this study was to explore whether activity-related pain and sensitization assessed via QST predict future pain, function, fatigue, physical performance and quality of life outcomes in those living in the community with knee OA. Eighty-six participants with knee OA were recruited in Dunedin, New Zealand. Those eligible to participate underwent baseline testing including QST as well as measures of activity-related pain including Movement-evoked Pain (MEP) and Sensitivity to Physical Activity (SPA). Outcome measures exploring pain, function, fatigue and quality of life outcomes were collected at baseline, and two follow-up periods (two and nine weeks). Univariable linear regression models were developed followed by multivariable linear regression models for each prognostic marker adjusting for age, gender, BMI, OA duration, baseline pain intensity and socioeconomic status. Activity-related measures of pain, including MEP and SPA, demonstrated predictive associations with pain and functional outcomes prospectively in those with knee OA. Therefore, those demonstrating activity-related pain are at future risk of greater pain, disability and reduced quality of life. Larger, externally validated longitudinal studies are required which include individuals with more severe knee OA.

No evidence for stratified exercise therapy being cost-effective compared to usual exercise therapy in patients with knee osteoarthritis: Economic evaluation alongside cluster randomized controlled trial

BACKGROUND

A stratified approach to exercise therapy may yield superior clinical and economic outcomes, given the large heterogeneity of individuals with knee osteoarthritis (OA).

OBJECTIVE

To evaluate the cost-effectiveness during a 12-month follow-up of a model of stratified exercise therapy compared to usual exercise therapy in patients with knee OA, from a societal and healthcare perspective.

METHODS

An economic evaluation was conducted alongside a cluster-randomized controlled trial in patients with knee OA (n = 335), comparing subgroup-specific exercise therapy for a 'high muscle strength subgroup', 'low muscle strength subgroup', and 'obesity subgroup' supplemented by a dietary intervention for the 'obesity subgroup' (experimental group), with usual ('non-stratified') exercise therapy (control group). Clinical outcomes included quality-adjusted life years - QALYs (EuroQol-5D-5 L), knee pain (Numerical Rating Scale) and physical functioning (Knee Injury and Osteoarthritis Outcome Score in daily living). Costs were measured by self-reported questionnaires at 3, 6, 9 and 12-month follow-up. Missing data were imputed using multiple imputation. Data were analyzed through linear regression. Bootstrapping techniques were applied to estimate statistical uncertainty.

RESULTS

During 12-month follow-up, there were no significant between-group differences in clinical outcomes. The total societal costs of the experimental group were on average lower compared to the control group (mean [95% confidence interval]: € 405 [-1728, 918]), albeit with a high level of uncertainty. We found a negligible difference in QALYs between groups (mean [95% confidence interval]: 0.006 [-0.011, 0.023]). The probability of stratified exercise therapy being cost-effective compared to usual exercise therapy from the societal perspective was around 73%, regardless of the willingness-to-pay threshold. However, this probability decreased substantially to 50% (willingness-to-pay threshold of €20.000/QALY) when using the healthcare perspective. Similar results were found for knee pain and physical functioning.

CONCLUSIONS

We found no clear evidence that stratified exercise therapy is likely to be cost-effective compared to usual exercise therapy in patients with knee OA. However, results should be interpreted with caution as the study power was lower than intended, due to the Coronavirus disease (COVID-19) pandemic.

Economic evaluation: a reader's guide to studies of cost-effectiveness

BACKGROUND

Understanding what an economic evaluation is, how to interpret it, and what it means for making choices in a health delivery context is necessary to contribute to decisions about healthcare resource allocation. The aim of this paper to demystify the working parts of a health economic evaluation, and explain to clinicians and clinical researchers how to read and interpret cost-effectiveness research.

MAIN BODY

This primer distils key content and constructs of economic evaluation studies, and explains health economic evaluation in plain language. We use the PICOT (participant, intervention, comparison, outcome, timeframe) clinical trial framework familiar to clinicians, clinical decision-makers, and clinical researchers, who may be unfamiliar with economics, as an aide to reading and interpreting cost-effectiveness research. We provide examples, primarily of physiotherapy interventions for osteoarthritis.

CONCLUSIONS

Economic evaluation studies are essential to improve decisions about allocating resources, whether those resources be your time, the capacity of your service, or the available funding across the entire healthcare system. The PICOT framework can be used to understand and interpret cost-effectiveness research.

The influence of manual therapy dosing on outcomes in patients with hip osteoarthritis: a systematic review

OBJECTIVE

To 1) Determine if specific dosing parameters of manual therapy are related to improved pain, disability, and quality of life outcomes in patients with hip osteoarthritis and 2) to provide recommendations for optimal manual therapy dosing based on our findings.

DESIGN

A systematic review of randomized controlled trials from the PubMed, CINAHL, and OVID databases that used manual therapy interventions to treat hip osteoarthritis was performed. Three reviewers assessed the risk of bias for included studies and extracted relevant outcome data based on predetermined criteria. Baseline and follow-up means and standard deviations for outcome measures were used to calculate effect sizes for within and between-group differences.

RESULTS

Ten studies were included in the final analyses totaling 768 participants, and half were graded as high risk of bias. Trends emerged: 1) large effect sizes were seen using long-axis distraction, mobilization and thrust manipulation, 2) mobilization with movement showed large effects for pain and range of motion, and (3) small effects were associated with graded mobilization. Durations of 10 to 30 minutes per session, and frequency 2-3 times per week for 2-6 weeks were the most common dosing parameters.

CONCLUSIONS

There were varied effect sizes associated with pain, function, and quality of life for both thrust and non-thrust mobilizations, and mobilization with movement into hip flexion and internal rotation. Due to the heterogeneity of MT dosage, it is difficult to recommend a specific manual therapy dosage for those with hip osteoarthritis.

The Benefits of Adding Manual Therapy to Exercise Therapy for Improving Pain and Function in Patients With Knee or Hip Osteoarthritis: A Systematic Review With Meta-analysis

OBJECTIVE: To evaluate if there was an additional benefit of combining manual therapy (MT) and exercise therapy over exercise therapy alone on pain and function in patients with hip or knee osteoarthritis. DESIGN: Intervention systematic review LITERATURE SEARCH: We (1) searched 4 databases from inception to June 20, 2021; (2) hand searched a reference list of included trials and relevant systematic reviews; and (3) contacted 2 researchers in the field. STUDY SELECTION CRITERIA: We included randomized controlled trials that compared MT and exercise therapy to similar exercise therapy programs alone in patients with hip or knee osteoarthritis. DATA SYNTHESIS: The data were combined using random-effects meta-analyses where appropriate. The certainty of evidence for each outcome was judged using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. RESULTS: We included 19 trials. There was very low to moderate certainty of evidence that MT added benefit in the short term for pain, and combined pain, function, and stiffness (WOMAC global scale), but not for performance-based function and self-reported function. In the medium term, there was low- to very-low-certainty evidence that MT added benefit for performance-based function and WOMAC global score, but not for pain. There was high-certainty evidence that MT provided no added benefit in the long term for pain and function. CONCLUSION: There was very low to moderate certainty of evidence supporting MT as an adjunct to exercise therapy for pain and WOMAC global scale, but not function in patients with knee or hip osteoarthritis in the short term. There was high certainty of evidence of no benefit for additional MT over exercise therapy alone in the long term. J Orthop Sports Phys Ther 2022;52(10):675-684. Epub: 27 July 2022. doi:10.2519/jospt.2022.11062.

Effectiveness of Maitland and Mulligan mobilization methods for adults with knee osteoarthritis: A systematic review and meta-analysis

BACKGROUND

As a serious global problem, knee osteoarthritis (KOA) often leads to pain and disability. Manual therapy is widely used as a kind of physical treatment for KOA.

AIM

To explore further the efficacy of Maitland and Mulligan mobilization methods for adults with KOA.

METHODS

We searched PubMed, the Cochrane Library, EMbase, Web of Science and Google Scholar from inception to September 20, 2020 to collect studies comparing Maitland and Mulligan mobilization methods in adults with KOA. The quality of the studies was assessed using the Physiotherapy Evidence Database Scale for randomized controlled trials. Data analyses were performed using Review Manager 5.0 software.

RESULTS

A total of 341 articles were screened from five electronic databases (PubMed, the Cochrane Library, EMbase, Web of Science and Google Scholar) after excluding duplicates. Ultimately, eight trials involving 471 subjects were included in present systematic review and meta-analysis. The mean PEDro scale score was 6.6. Mulligan mobilization was more effective in alleviating pain [standardized mean difference (SMD) = 0.60; 95% confidence interval (CI): 0.17 to 1.03, P = 0.007; I 2 = 60%, P = 0.020) and improving Western Ontario and McMaster Universities function score (SMD = 7.41; 95%CI: 2.36 to 12.47, P = 0.004; I 2 = 92%, P = 0.000). There was no difference in the effect of the two kinds of mobilization on improving the range of motion (SMD = 9.63; 95%CI: -1.23 to 20.48, P = 0.080; I 2 = 97%, P = 0.000).

CONCLUSION

Mulligan mobilization technique is a promising intervention in alleviating pain and improving function score in KOA patients.

Cost-effectiveness of an 8-week supervised education and exercise therapy programme for knee and hip osteoarthritis: a pre-post analysis of 16 255 patients participating in Good Life with osteoArthritis in Denmark (GLA:D)

OBJECTIVES

To evaluate 1-year cost-effectiveness of an 8-week supervised education and exercise programme delivered in primary care to patients with symptomatic knee or hip osteoarthritis (OA).

DESIGN

A registry-based pre-post study linking patient-level data from the Good Life with osteoArthritis in Denmark (GLA:D) registry to national registries in Denmark.

SETTING AND PARTICIPANTS

16 255 patients with symptomatic knee or hip OA attending GLA:D.

INTERVENTION

GLA:D is a structured supervised patient education and exercise programme delivered by certified physiotherapists and implemented in Denmark.

OUTCOME MEASURES

Adjusted healthcare costs per Quality-Adjusted Life Year (QALY) gained from baseline to 1 year (ratio of change in healthcare costs to change in EuroQoL 5-Dimensions 5-Level questionnaire (EQ-5D)). All adjusted measures were estimated using a generalised estimating equation gamma regression model for repeated measures. Missing data on EQ-5D were imputed with Multiple Imputations (3 months: 23%; 1 year: 39 %).

RESULTS

Adjusted change in healthcare cost was 298€ (95% CI: 206 to 419) and 640€ (95% CI: 400 to 1009) and change in EQ-5D was 0.035 (95% CI: 0.033 to 0.037) and 0.028 (95% CI: 0.025 to 0.032) for knee and hip patients, respectively. Hence estimated adjusted healthcare costs per QALY gained was 8497€ (95% CI: 6242 to 11 324) for knee and 22 568€ (95% CI: 16 000 to 31 531) for hip patients. In patients with high compliance, the adjusted healthcare costs per QALY gained was 5438€ (95% CI: 2758 to 9231) for knee and 17 330€ (95% CI: 10 041 to 29 364) for hip patients. Healthcare costs per QALY were below conventional thresholds for willingness-to-pay at 22 804€ (20 000£) and 43 979€ (US$50 000), except the upper limit of the 95% CI for hip patients which was in between the two thresholds.

CONCLUSIONS

A structured 8-week supervised education and exercise programme delivered in primary care was cost-effective at 1 year in patients with knee or hip OA supporting large-scale implementation in clinical practice.

Are manual therapy or booster sessions worthwhile in addition to exercise therapy for knee osteoarthritis: Economic evaluation and 2-year follow-up of a randomized controlled trial

BACKGROUND

Exercise therapy is known to be an effective intervention for patients with osteoarthritis, however the evidence is limited as to whether adding manual therapy or booster sessions are cost-effective strategies to extend the duration of benefits.

OBJECTIVE

To investigate the cost-effectiveness, at 2-year follow-up, of adding manual therapy and/or booster sessions to exercise therapy.

DESIGN

2-by-2 factorial randomized controlled trial.

METHODS

Participants with knee osteoarthritis were randomly allocated (1:1:1:1) to: exercise therapy delivered in consecutive sessions within 9 weeks (control group), exercise therapy distributed over 1 year using booster sessions, exercise therapy plus manual therapy delivered within 9 weeks, and exercise therapy plus manual therapy with booster sessions. The primary outcome was incremental cost-effectiveness from health system and societal perspectives interpreted as incremental net monetary benefit (INMB).

RESULTS

Of 75 participants, 66 (88 %) were retained at 1-year and 40 (53 %) at 2-year follow-up. All three interventions were cost-effective from both the health system and societal perspectives (INMBs, at 0.5 × GDP/capita willingness to pay (WTP) threshold: $3278 (95%CI -3244 to 9800) and $3904 (95%CI -2823 to 10,632) respectively for booster sessions; $2941 (95%CI -3686 to 9568) and $2618 (95%CI -4005 to 9241) for manual therapy; $270 (95%CI -6139 to 6679) and $404 (95%CI -6097 to 6905) for manual therapy with booster sessions).

CONCLUSION

Manual therapy or booster sessions in addition to exercise therapy are cost-effective at 2-year follow-up. The evidence did not support combining both booster sessions and manual therapy in addition to exercise therapy.

Reported practices related to, and capability to provide, first-line knee osteoarthritis treatments: a survey of 1064 Australian physical therapists

BACKGROUND

Physical therapists play a key role in providing first-line knee osteoarthritis treatments, including patient education and exercise therapy.

OBJECTIVES

Describe Australian physical therapists' awareness of guidelines; reported practices; and beliefs about capability, opportunity, motivation, and evidence.

METHODS

An online cross-sectional survey was completed by physical therapists prior to attending the Good Living with osteoArthritis from Denmark (GLA:D®) Australia training courses (March 2017 to December 2019). The survey instrument was developed by an expert panel and was informed by the Theoretical Domains Framework.

RESULTS

1064 physical therapists from all Australian states and territories participated. 11% (n = 121) could name an accepted guideline, 98% agreed it was their job to deliver patient education and exercise therapy, and 92% agreed this would optimise outcomes. Most reported providing strength exercise (99%), written exercise instructions (95%), treatment goal discussion (88%), and physical activity advice (83%) all or most of the time. Fewer provided aerobic exercise (66%), neuromuscular exercise (54%), and weight management discussion (56%) all or most of the time. Approximately one quarter (23-24%) believed they did not have the skills, knowledge, or confidence to provide education and exercise therapy recommended by guidelines, and just 48% agreed they had been trained to do so.

CONCLUSION

Australian physical therapists treating knee osteoarthritis typically provide strength-based home exercise with written instructions, alongside goal setting and physical activity advice. Just one in nine could name a guideline. Education and training activities are needed to support physical therapists to access, read and implement guidelines, especially for aerobic and neuromuscular exercise, and weight management.

Measurement Instruments of Productivity Loss of Paid and Unpaid Work: A Systematic Review and Assessment of Suitability for Health Economic Evaluations From a Societal Perspective

OBJECTIVES

This study aimed (1) to perform a systematic literature review of instruments for measuring productivity loss of paid and unpaid work and (2) to assess the suitability (in terms of identification, measurement, and valuation) of these instruments for use in health economic evaluations from a societal perspective.

METHODS

Articles published from 2018 were sourced from PubMed/Medline, PsycInfo, Embase, and Econlit. Using 2 separate search strategies, eligible economic evaluations and validation studies were selected and unique measurement instruments identified. A data-extraction form was developed by studying previous literature and consulting an international panel of experts in the field of productivity costs. This data-extraction form was applied to assess the suitability of instruments for use in economic evaluations.

RESULTS

A total of 5982 articles were retrieved from the databases, of which 99 economic evaluations and 9 validation studies were included in the review. A total of 42 unique measurement instruments were identified. Nine instruments provided quantified measures of absenteeism, presenteeism, and unpaid work. Five instruments supplied the necessary information to enable the use of at least 1 common valuation method. The Health and Labour Questionnaire-Short Form, Health and Labour Questionnaire, and Institute for Medical Technology Assessment Productivity Cost Questionnaire met both criteria. Nevertheless, the developers replaced the Health and Labour Questionnaire-Short Form and Health and Labour Questionnaire by the more recently developed Institute for Medical Technology Assessment Productivity Cost Questionnaire.

CONCLUSIONS

Although many instruments for measuring productivity loss were identified, most were not suitable for capturing productivity changes for economic evaluations from a societal perspective. Future research can benefit from this study by making an informed instrument choice for the measurement of productivity loss of paid and unpaid work.

How Do People Communicate About Knee Osteoarthritis? A Discourse Analysis

OBJECTIVE

To explore the ways in which people talk about knee osteoarthritis and how this may influence engagement in physical activity and activity-based interventions as recommended by clinical practice guidelines.

DESIGN

A qualitative synthesis using discourse analysis methods.

METHODS

Systematic review methods were used to identify qualitative studies exploring the perceptions of people with knee osteoarthritis, their carers, and/or clinicians. Methodological quality was evaluated through the use of the Critical Appraisal Skills Programme. Raw quotes extracted from each study were analyzed with inductive discourse analysis.

RESULTS

A search of five electronic databases from inception until August 2019 yielded 778 articles. Sixty-two articles from 56 studies were included, reporting data (1,673 direct quotes) from people with knee osteoarthritis, carers, and clinicians in 16 countries. Two overarching discourses were identified-impairment and participation. The overarching impairment discourse prevailed in all participant groups and study settings. In this discourse, knee osteoarthritis was likened to a machine that inevitably wore down over time and required a doctor to repair. The overarching participatory discourse almost always coexisted alongside an impairment discourse. According to this discourse, a "busy body" was perceived as "healthy," and people could remain active despite knee osteoarthritis.

CONCLUSION

The prevailing impairment discourse may potentially discourage people from using knees that have passed their "use-by date" and increase reliance on doctors to repair joint damage. Consistent with recommendations in clinical practice guidelines, a participatory discourse may provide an alternative way of communicating that may encourage people with knee osteoarthritis to continue to engage in physical activity by focusing on what they can do, rather than what they cannot do.

Total Hip and Knee Arthroplasties Are Highly Cost-Effective Procedures: The Importance of Duration of Follow-Up

BACKGROUND

Total hip and knee arthroplasties (THA/TKA) are clinically effective but high cost procedures. The aim of this study is to perform a cost-effectiveness analysis of THA and TKA in the New Zealand (NZ) healthcare system.

METHODS

Data were collected from 713 patients undergoing THA and 520 patients undergoing TKA at our local public hospital. SF-6D utility values were obtained from participants preoperatively and 1-year postoperatively, and deaths and any revision surgeries from patient records and the New Zealand Joint Registry at minimum 8-year follow-up. A continuous-time state-transition simulation model was used to estimate costs and health gains to 15 years. Quality-adjusted life years (QALYs), treatment costs, and incremental cost-effectiveness ratios (ICERs) were calculated to determine cost effectiveness. ICERs below NZ gross domestic product (GDP; NZ$60 600) and 0.5 times GDP per capita were considered "cost effective" and "highly cost effective" respectively.

RESULTS

Cumulative health gains were 2.8 QALYs (THA) and 2.3 QALYs (TKA) over 15 years. Cost effectiveness improved from ICERs of NZ$74,400 (THA) and NZ$93,000 (TKA) at 1 year to NZ$6000 (THA) and NZ$7500 (TKA) at 15 years. THA and TKA were cost effective after 2 years and highly cost effective after 3 years. QALY gains and cost effectiveness were greater in patients with worse preoperative functional status and younger age.

CONCLUSION

THA and TKA are highly cost-effective procedures over longer term horizons. Although preoperative status and age were associated with cost effectiveness, both THA and TKA remained cost effective in patients with less severe preoperative scores and older ages.

Are education, exercise and diet interventions a cost-effective treatment to manage hip and knee osteoarthritis? A systematic review

OBJECTIVE

To identify research gaps and inform implementation we systematically reviewed the literature evaluating cost-effectiveness of recommended treatments (education, exercise and diet) for the management of hip and/or knee OA.

METHODS

We searched Medline, Embase, Cochrane Central Register of Controlled Trials, National Health Services Economic Evaluation Database, and EconLit from inception to November 2019 for trial-based economic evaluations investigating hip and/or knee OA core treatments. Two investigators screened relevant publications, extracted data and synthesized results. Risk of bias was assessed using the Consensus on Health Economic Criteria list.

RESULTS

Two cost-minimization, five cost-effectiveness and 16 cost-utility analyses evaluated core treatments in six health systems. Exercise therapy with and without education or diet was cost-effective or cost-saving compared to education or physician-delivered usual care at conventional willingness to pay (WTP) thresholds in 15 out of 16 publications. Exercise interventions were cost-effective compared to physiotherapist-delivered usual care in three studies at conventional WTP thresholds. Education interventions were not cost-effective compared to usual care or placebo at conventional WTP thresholds in three out of four publications.

CONCLUSIONS

Structured core treatment programs were clinically effective and cost-effective, compared to physician-delivered usual care, in five health care systems. Providing education about core treatments was not consistently cost-effective. Implementing structured core treatment programs into funded clinical pathways would likely be an efficient use of health system resources and enhance physician-delivered usual primary care.

Improving function in people with hip-related pain: a systematic review and meta-analysis of physiotherapist-led interventions for hip-related pain

OBJECTIVE

To report the effectiveness of physiotherapist-led interventions in improving pain and function in young and middle-aged adults with hip-related pain.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

A comprehensive, reproducible search strategy was performed on five databases in May 2019. Reference lists and grey literature were also searched.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Population: people aged ≥18 years with hip-related pain (with or without a diagnosis of femoroacetabular impingement syndrome).

INTERVENTION(S)

physiotherapist-led interventions for hip pain. Comparators: sham treatment, no treatment or other treatment (eg, hip arthroscopic surgery).

OUTCOMES

primary outcomes included patient-reported hip pain and function. Secondary outcomes included physical function measures.

RESULTS

1722 papers were identified. After exclusion criteria were applied, 14 studies were included for analysis. They had varied risk of bias. There were no full-scale placebo-controlled randomised controlled trials (RCTs) of physiotherapist-led treatment. Pooled effects ranged from moderate effects (0.67 (95% CI 0.07 to 1.26)) favouring physiotherapist-led intervention over no treatment post-arthroscopy, to weak effects (-0.32 (95% CI 0.57 to 0.07)) favouring hip arthroscopy over physiotherapist-led treatment.

CONCLUSION

Physiotherapist-led interventions might improve pain and function in young and middle-aged adults with hip-related pain, however full-scale high-quality RCT studies are required.

A systematic review and meta-analysis of health state utility values for osteoarthritis-related conditions

BACKGROUND

Health state utility values (HSUVs) are a key input in health economic modelling but HSUVs of people with osteoarthritis (OA)-related conditions have not been systematically reviewed and meta-analysed.

OBJECTIVE

To systematically review and meta-analyse the HSUVs for people with OA.

METHODS

Searches within health economic/biomedical databases were performed to identify eligible studies reporting OA-related HSUVs. Data on study design, participant characteristics, affected OA joint sites, treatment type, HSUV elicitation method, considered health states, and the reported HSUVs were extracted. HSUVs for people with knee, hip and mixed OA in pre- and post-treatment populations were meta-analysed using random effects models.

RESULTS

One-hundred and fifty-one studies were included in the systematic review, and 88 in meta-analyses. Of 151 studies, 56% were conducted in Europe, 75% were in people with knee and/or hip OA and 79% were based on the EQ-5D. The pooled mean (95% confidence interval [CI]) baseline HSUVs for knee OA core interventions, medication, injection and primary surgery treatments were 0.64 (0.61-0.66), 0.56 (0.45-0.68), 0.58 (0.50-0.66) and 0.52 (0.49-0.55), respectively. These were 0.71 (0.59-0.84) for hip OA core interventions and 0.52 (0.49-0.56) for hip OA primary surgery. For all knee OA treatments and hip OA primary surgery, pooled HSUVs were significantly higher in the post- than the pre- treatment populations.

CONCLUSION

This study provides a comprehensive summary of OA-related HSUVs and generates a HSUVs database for people with different affected OA joint sites undergoing different treatments to guide HSUV choices in future health economic modelling of OA interventions.

Guidance for implementing best practice therapeutic exercise for people with knee and hip osteoarthritis: what does the current evidence base tell us?

OBJECTIVE

Therapeutic exercise is a recommended first-line treatment for people with knee and hip osteoarthritis. However, there is little specific advice or practical resources to guide clinicians in its implementation. As the first in a series of projects by the Osteoarthritis Research Society International Rehabilitation Discussion Group to address this gap, we aim to synthesize current literature informing the implementation of therapeutic exercise for people with knee and hip osteoarthritis.

METHODS

Narrative review focusing on evidence from systematic reviews and randomized controlled trials.

RESULTS

Therapeutic exercise is safe for people with knee and hip osteoarthritis. Numerous types of therapeutic exercise (including aerobic, strengthening, neuromuscular, mind-body exercise) may be utilised at varying doses and in different settings to improve pain and function. Benefits from therapeutic exercise appear greater when dosage recommendations from general exercise guidelines for healthy adults are met. However, interim therapeutic exercise goals may also be useful, given that many barriers to achieving these dosages exist among this patient group. Theoretically-informed strategies to improve adherence to therapeutic exercise, such as patient education, goal setting, monitoring and feedback, may help maintain participation and optimise clinical benefits over the longer-term. Sedentary behaviour is also a risk factor for disability and lower quality of life in people with knee and hip osteoarthritis, although limited evidence exists regarding how best to reduce this behaviour.

CONCLUSION

Current evidence can be used to inform how to implement best practice therapeutic exercise, at a sufficient and appropriate dose, for people with knee and hip osteoarthritis.

Cost-effectiveness of 12 weeks of supervised treatment compared to written advice in patients with knee osteoarthritis: a secondary analysis of the 2-year outcome from a randomized trial

OBJECTIVE

To assess the 24-month cost-effectiveness of supervised treatment compared to written advice in knee osteoarthritis (OA).

DESIGN

100 adults with moderate-severe OA not eligible for total knee replacement (TKR) randomized to a 12-week individualized, supervised treatment (exercise, education, diet, insoles and pain medication) or written advice. Effectiveness was measured as change in quality-adjusted life years (QALYs) from baseline to 24 months, including data from baseline, 3, 6, 12 and 24 months, while healthcare costs and transfer payments were derived from national registries after final follow-up. Incremental costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs) were calculated. A sensitivity analysis resampling existing data was conducted and the probability of cost-effectiveness was estimated using a 22,665 Euros/QALY threshold. In a sensitivity analysis, cost-effectiveness was calculated for different costs of the supervised treatment (actual cost in study; cost in private practice; and in-between cost).

RESULTS

Average costs were similar between groups (6,758 Euros vs 6,880 Euros), while the supervised treatment were close to being more effective (incremental effect (95% CI) of 0.075 (-0.005 to 0.156). In the primary analysis excluding deaths, this led the supervised treatment to be cost-effective, compared to written advice. The sensitivity analysis demonstrated that the results were sensitive to changes in the cost of treatment, but in all scenarios the supervised treatment was cost-effective (ICERs of 6,229 to 20,688 Euros/QALY).

CONCLUSIONS

From a 24-month perspective, a 12-week individualized, supervised treatment program is cost-effective compared to written advice in patients with moderate-severe knee OA not eligible for TKR.

Minimally Invasive Therapies for Osteoarthritic Hip Pain: a Comprehensive Review

PURPOSE OF REVIEW

Osteoarthritis (OA) is a highly prevalent cause of chronic hip pain, affecting 27% of adults aged over 45 years and 42% of adults aged over 75 years. Though OA has traditionally been described as a disorder of "wear-and-tear," recent studies have expanded on this understanding to include a possible inflammatory etiology as well, damage to articular cartilage produces debris in the joint that is phagocytosed by synovial cells which leads to inflammation.

RECENT FINDINGS

Patients with OA of the hip frequently have decreased quality of life due to pain and limited mobility though additional comorbidities of diabetes, cardiovascular disease, poor sleep quality, and obesity have been correlated. Initial treatment with conservative medical management can provide effective symptomatic relief. Physical therapy and exercise are important components of a multimodal approach to osteoarthritic hip pain. Patients with persistent pain may benefit from minimally invasive therapeutic approaches prior to consideration of undergoing total hip arthroplasty. The objective of this review is to provide an update of current minimally invasive therapies for the treatment of pain stemming from hip osteoarthritis; these include intra-articular injection of medication, regenerative therapies, and radiofrequency ablation.

Autologous cell-free serum preparations in the management of knee osteoarthritis: what is the current clinical evidence?

Background

There is paucity in the current literature regarding clinical outcomes of autologous cell-free serum preparations. The objective of this paper is to collate the clinical evidence and review the results of intraarticular injections of autologous cell-free serum preparations in the management of knee osteoarthritis (OA).

Methods

A comprehensive English literature search was undertaken using the healthcare database website (https://hdas.nice.org.uk/). The PubMed, Medline, CINAHL, Embase and the Cochrane library databases were searched to identify all studies of autologous protein solution/autologous conditioned serum (ACS/APS) in the management of knee OA. We evaluated the reported clinical outcomes with respect to pain, function, morbidity, adverse effects and complications.

Results

Fifteen relevant articles were identified in the current literature. Outcomes following injection of ACS/APS have been reported in patients with age range (34–87 years) and unilateral or bilateral knee OA. Seven studies reported improvement in visual analog scale (VAS) whereas the Western Ontario and McMaster Universities osteoarthritis instrument (WOMAC) score improved in nine studies. Considerable variation was noted in the injection technique and duration of post-procedure assessment with only one study reporting long-term follow-up beyond 24 months. Joint swelling and injection-site pain were reported to be the most common complications; only one study reported a case of septic arthritis. However, no evidence is available to clearly identify factors that may predict the outcomes following this procedure.

Conclusion

Current data from the clinical studies would suggest that the intraarticular administration of autologous cell-free serum preparations, such as ACS/APS, in patients with knee OA may improve pain and function, with limited morbidity. High-quality clinical trials with stratified patient cohorts, longer follow-up duration and robust reporting of outcome measures are essential to improve the understanding of the indications and clinical effectiveness of these novel products.

Self-Management of Hip Osteoarthritis Five Years After a Cycling and Education Treatment Pathway

The Cycling against Hip Pain (CHAIN) programme is a six-week cycling and education treatment pathway for people with hip osteoarthritis. Preliminary results demonstrated significant improvements in clinical and patient-reported outcome measures following the course. Whilst the benefits of exercise for osteoarthritis are often reported in the short term, less is known about the long-term effects for this patient group. This study explores whether participants continued to self-manage their hip osteoarthritis five years after completing the course. A cross-sectional survey was conducted to collect data from participants who completed the CHAIN programme between October 2013 and February 2015 (n = 96). Questionnaires were sent by post in April 2019, and then non-responders were followed up again four weeks later. Eighty-three (87%) participants responded to the survey. Five years (range 4–6) after completion of a six-week cycling and education programme, 37 (45%) participants had not returned to their general practitioner for further treatment of their hip pain, and 47 (57%) had not pursued surgical intervention. All participants were still engaged in at least one physical activity per week and many reported that they had purchased a bike (29%), joined a gym (30%) or cycled regularly (indoor cycling 25%, outdoor cycling 24%). Eighty (96%) participants reported an increase in knowledge of self-managing their symptoms. The findings from this study suggest that many patients are motivated to self-manage their hip osteoarthritis, five years following a six-week cycling and education treatment pathway that encourages lifestyle change.

'My hip is damaged': a qualitative investigation of people seeking care for persistent hip pain

OBJECTIVES

Clinicians who use the biopsychosocial approach to manage musculoskeletal pain disorders aim to understand how patients make sense of their symptoms. Treatment includes targeting the negative beliefs and coping responses that can lead to progressive pain and disability. We aimed to explore how people seeking care for persistent hip pain and disability make sense of their symptoms.

METHODS

Cross-sectional qualitative study. People were eligible if they were aged ≥18 years, were consulting an orthopaedic surgeon for persistent hip pain and offered a non-surgical intervention. Data were collected through interviews that explored patients' beliefs about the identity (diagnosis), causes, consequences, timeline and controllability of their symptoms, their strategies to cope with pain and their experiences in seeking healthcare. Transcribed interview data were analysed thematically using a framework approach.

RESULTS

Sixteen people (median age=51, range=33-73 years; median duration hip pain=3 years, range=3 months-20 years) participated. Most participants (10/16) believed their pain was caused by an exercise-related injury. Because of the results of imaging and interactions with healthcare professionals, all participants believed they had damaged hip structures. All described ineffective strategies to manage their pain and multiple failed treatments. For many (7/16), a lack of control over symptoms threatened their physical and mental health.

CONCLUSIONS

The way participants with persistent hip pain and disability made sense of their symptoms contributed to them avoiding physical activity, and it impaired their sleep, emotional well-being and physical health.

The Effect of the Phytocomplex Electrophoresis on the Clinical Symptomatology and Quality of Life of Patients with the Knee Joint Osteoarthritis

BACKGROUND:

Improving the effectiveness of rehabilitation of patients with osteoarthritis necessitates the use of drug electrophoresis with sinusoidal modulated currents (SMC-electrophoresis) in conjunction with drug therapy. The phytocomplex is proposed for electrophoresis composed of the compared, alfalfa and hops dry extract, containing flavonoids, coumestans, polysaccharides, steroids, essential amino acids, vitamins, mineral components and causing its possible use in osteoarthritis.

AIM:

The research aims to study the effect of the phytocomplex SMC-electrophoresis on the clinical symptoms and quality of life of patients with the knee joint osteoarthritis.

METHODS:

One hundred and eight patients were randomly distributed into 3 groups (n = 36). The phytocomplex SMC-electrophoresis was assigned to the first group, the amplipulse therapy (SMC) – to the second group, and the “basic” drug therapy – to the third group. The drug therapy of the patients of the third group was comparable with the drug treatment of those in the first two groups. The concentration of phytocomplex in the working solution was 10%. The electrotherapy was carried out in the aligned SMC mode in the first and fourth kind of works. Comparative indicators were as follows: WOMAC index, pain level on a visual analogue scale (VAS), Lequesne index, joint range of motion (JROM), articular and tendon indices, quality of life as per Health Assessment Questionnaire (HAQ).

RESULTS:

The use of the phytocomplex SMC-electrophoresis had a more pronounced positive effect on pain, knee joint function and quality of life of the patients compared with the treatment with drugs alone or using amplitude therapy. This was especially pronounced immediately after the rehabilitation. The analgesic effect was consistently maintained in the patients of the first group for up to 6 – 12 months, the second group – up to 3 – 6 months in terms of the level of pain according to the WOMAC and Lequesne indices, VAS, articular and tendon indices. Stable results have been obtained for improving the functions of the knee joint for up to 6 – 12 months using the phytocomplex SMC-electrophoresis as per the WOMAC and Lequesne indices. In the treatment by the phytocomplex SMC-electrophoresis, no side effects were registered.

CONCLUSION:

The obtained results give grounds for further research on the evaluation of the effectiveness of using the phytocomplex SMC-electrophoresis in microcirculatory disorders in the affected joint, for correcting connective tissue metabolism and electrolyte metabolism in the patients with the knee joint osteoarthritis.

Implementation of a 'Joint Clinic' to resolve unmet need for orthopaedic services in patients with hip and knee osteoarthritis: a program evaluation

Background

Osteoarthritis is the most common form of arthritis, principally affecting the older population. Highly prevalent, disabling diseases such as osteoarthritis strain the capacity of health systems, and can result in unmet need for services. The Joint Clinic was initiated to provide secondary care consultations and access to outpatient services for people with advanced hip or knee osteoarthritis, who were referred by their general practitioner for orthopaedic consultation but not offered an orthopaedic specialist appointment.

Methods

This longitudinal programme evaluation comprised four components: a proof-of-concept evaluation; an implementation evaluation; a process evaluation; and an outcomes evaluation. Interviews and surveys of general practitioners, staff, and patients were conducted pre- and post-implementation. Interviews were transcribed, and thematic analysis was completed. In addition, Joint Clinic patient visits and outcomes were reviewed.

Results

One hundred and eleven primary care physicians (GPs) and 66 patients were surveyed, and 28 semi-structured interviews of hospital staff and GPs were conducted. Proof of concept was satisfied. Interim and final implementation evaluations indicated adherence to the concept model, high levels of acceptance of and confidence in the programme and its staff, and timely completion within budget. Process evaluation revealed positive impacts of the programme and positive stakeholder perceptions, with some weaknesses in communication to the outer context of primary care. The Joint Clinic saw a total of 637 patient visits during 2 years of operation. Unmet need was reduced by 90%. Patient and referring physician satisfaction was high. Hospital management confirmed that the programme will continue.

Conclusions

This evaluation indicates that the Joint Clinic concept model is fit for purpose, functioned well within the organisation, and achieved its primary objective of reducing unmet need of secondary care consultation for those suffering advanced hip or knee osteoarthritis.
