Unintended consequences: quantifying the benefits, iatrogenic harms and downstream cascade costs of musculoskeletal MRI in UK primary care

Co-creating a Choosing Wisely leaflet supporting the reduction of imaging usage in low back pain management - A multi-method study

OBJECTIVE

The objective was to co-create an information resource in the form of a leaflet, to be distributed in clinical settings, websites or social media targeting people with low back pain.

METHODS

This multi-method study was conducted in four stages: literature search, input from practice consultants, program theory development, and think-aloud interviews with people experiencing low back pain. Each stage was followed by a consensus meeting in which the steering group refined the leaflet based on the emerging knowledge.

RESULTS

The literature search highlighted patients' need for easy-to-understand information about their back pain diagnosis, management strategies, social activities, work and solutions for supported self-management strategies. Practice consultants emphasized concise, relatable content. The program theory identified potential mechanisms for content creation, development, and implementation of the leaflet, such as addressing patient concerns, reducing diagnostic uncertainty, insights into management options, and validation. Think-aloud interviews with 18 people living with low back pain informed the iteration of the leaflet, enhancing language clarification and content comprehension.

CONCLUSIONS

We co-created a new Choosing Wisely leaflet, created with end-users in mind, specifically focused on reducing unnecessary imaging for low back pain.

PRACTICE IMPLICATIONS

This leaflet may support clinical settings in delivering evidence-based approaches and supporting self-management.

Evaluating musculoskeletal imaging communication interventions using behavioural science: a scoping review using the COM-B model

OBJECTIVES

Clinicians and patients have been found to attribute musculoskeletal (MSK) pain to normal age-related changes seen on imaging, which can negatively impact patient outcomes and increase healthcare costs. While some studies have tested interventions to improve how MSK imaging findings are communicated, their impact has been limited. Applying a behavioural science framework has the potential to identify the rationale and target of these interventions to inform future intervention design-an analysis that has not yet been conducted. This study aims to identify the Behaviour Change Techniques (BCTs), the behavioural targets and the theoretical basis of interventions seeking to affect the communication of MSK imaging.

DESIGN

Scoping review using the Capability, Opportunity, Motivation - Behaviour (COM-B) model.

DATA SOURCES

Searches of MEDLINE, EMBASE, CINAHL, AMED and PsycINFO from inception to 9 February 2024.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We included studies that have developed or evaluated interventions which target the communication of MSK imaging findings. Interventions targeting both patients and clinicians were included. Experimental and quasi-experimental study designs were included, and studies that focused on serious or specific known causes of MSK pain were excluded.

DATA EXTRACTION AND SYNTHESIS

Two independent authors extracted study participant data and intervention details. A theory of behaviour called the COM-B model was used to map the BCTs and behavioural components targeted by studies.

RESULTS

We identified 11 studies from 2486 studies in our electronic search. 11 different BCTs were identified across 11 studies. The most common techniques were framing/reframing (nine studies), adding objects to the environment (eight studies), incompatible beliefs (seven studies) and avoidance/reducing exposure to cues for the behaviour (four studies). Only two studies (feasibility studies) used behavioural theory to guide their intervention design. While one study showed a large effect, most interventions had little to no impact on pain, disability, or fear over time.

CONCLUSION

This review highlighted a lack of studies targeting clinician knowledge and the provision of high-quality patient resources about the nature of MSK pain, even though the broader literature identifies both as enablers of effective health communication. Additionally, the absence of a theory-informed design likely resulted in attempts to reassure patients about normal age-related imaging findings without providing an alternate, more coherent explanation for symptoms. Future interventions should focus on enhancing clinician psychological capability (knowledge) as well as clinician and patient reflective motivation (beliefs) to enable more helpful explanations of MSK symptoms. The key challenge for future interventions will be achieving these aims in a way that is effective, consistent and practical.

Overuse of medical imaging and effects of payer-provider integration: quasi-experimental evidence from Finland

BACKGROUND

Healthcare expenditures have risen in middle- and high-income countries. One of the potential contributors is the overuse of diagnostics. I explore whether medical imaging is overused when privately owned clinics in Finland treat patients with voluntary private health insurance (VPHI).

METHODS

I employ administrative insurance claims data from a major Finnish insurance company, covering 2016-2019, and exploit two market entries of clinics owned by the company in 2017. The underlying assumption is that the insurance company's own clinics had weaker incentives to overuse imaging than other privately owned clinics because the payer and the provider belonged to the same entity. I identify the overuse using the staggered difference-in-differences (DID) strategy, in which I consider patients from cities with a market entry as the treatment group and compare them to patients in other similar cities.

RESULTS

I find that the market entries decreased the use of radiography and ultrasound imaging in the treatment of VPHI policyholders, suggesting that private clinics overused these imaging technologies. The more expensive computed tomography (CT) and magnetic resonance imaging (MRI) were, however, not overused.

CONCLUSIONS

The results show that private clinics in Finland overused some imaging technologies when treating VPHI policyholders. The extent and magnitude of overuse can, however, vary considerably between imaging technologies and medical ailments.

Knowledge translation and exercise for degenerative meniscal pathology and early osteoarthritis (KNEE-DEeP): Protocol for a single arm feasibility study

Background

The Knowledge Translation and Exercise for Degenerative Meniscal Pathology and Early Knee Osteoarthritis (KNEE-DEeP) intervention was designed to promote greater uptake of evidence-based non-surgical treatments for knee pain attributed to degenerative meniscal pathology and early knee osteoarthritis (OA) in primary care, by tackling barriers at a service, clinician and patient level. Evidence indicates that patients frequently do not access first-line treatments, namely exercise and patient education, prior to specialist referral. The KNEE-DEeP intervention supports general practitioners (GPs) and physiotherapists to enhance their skills and confidence in managing patients with this type of knee pain through professional development workshops. In turn, patients will receive an 'enhanced consultation' from their GP and be referred to an early 'best practice' physiotherapy session. Physiotherapists will work with patients to develop a collaborative action plan focussing on self-management and exercise.

Methods

This protocol outlines a single arm non-randomised feasibility study with a mixed method process evaluation. The study intends to recruit 15 GPs, five physiotherapists and 36 patients from general practices in the South-West of Ireland. Eligible patients, will be aged between 35 years and 69 years inclusive, and attend their GP with an episode of non-traumatic knee pain attributed to a degenerative meniscal tear (DMT) or early OA. Physiotherapists and GPs will be trained in intervention delivery. Within two weeks of receiving an 'enhanced consultation' from their participating GP, patients will attend the one-hour 'best practice' physiotherapy session. Patient data will be collected via online questionnaires at baseline, 12 weeks and 6 months. Qualitative interviews to assess the feasibility and acceptability of the intervention will be conducted with a purposive sample of GPs, physiotherapists and their enrolled patients.

Ethics and Dissemination

Approved by Clinical Research Ethics Committee of the Cork Teaching Hospitals. Results will be presented in peer-reviewed journals and at international conferences.

Theory-Informed Development of a Multicomponent Intervention to Implement Clinical Practice Guideline Recommendations in the Management of Shoulder Pain

OBJECTIVE

Suboptimal primary health care management of shoulder pain has been reported in previous studies. Implementing clinical practice guidelines (CPGs) recommendations using a theoretical approach is recommended to improve shoulder pain management. This study aims to identify determinants of implementing recommendations from shoulder CPGs to help develop an intervention based on the identified determinants.

METHODS

Family physicians and physical therapists managing patients with shoulder pain in primary care were invited to participate in a qualitative study to identify determinants to implementing recommendations from shoulder CPGs. The Theoretical Domains Framework (TDF) was used to inform the creation of the semi-structured interview guide and for deductive coding of transcriptions. The determinants were mapped to intervention functions and behavior change techniques (BCT) using the Behavior Change Wheel method and strategies for implementing CPGs recommendations were identified.

RESULTS

Interviews were conducted with 16 family physicians and 19 physical therapists. We identified 12 barriers and 6 facilitators within 7 TDF domains: knowledge, skills, beliefs about capabilities, beliefs about consequences, intentions, environmental context and resources, and social influence. We identified 6 intervention functions and 12 BCT addressing the relevant determinants. The 11 implementation strategies identified include the development and distribution of educational material, interactive educational outreach visits, and audit and feedback. Other components to consider are the identification and preparation of champions in primary care clinical settings, revision of professional roles, and creation of interdisciplinary clinical teams.

CONCLUSIONS

The identification of barriers and facilitators to implementing recommendations from shoulder CPGs allowed us to select implementation strategies at individual and organizational levels.

IMPACT

The implementation strategies will be adapted to specific primary care contexts in consultation with stakeholders and operationalized into a multicomponent implementation intervention. Implementing the intervention has the potential to improve shoulder pain management in primary care and facilitate the use of evidence-based recommendations from CPGs.

Clinical and cost-effectiveness of first contact physiotherapy for musculoskeletal disorders in primary care: the FRONTIER, mixed method realist evaluation

Background

First-contact physiotherapists assess and diagnose patients with musculoskeletal disorders, determining the best course of management without prior general practitioner consultation.

Objectives

The primary aim was to determine the clinical and cost-effectiveness of first-contact physiotherapists compared with general practitioner-led models of care.

Design

Mixed-method realist evaluation of effectiveness and costs, comprising three main phases: A United Kingdom-wide survey of first contact physiotherapists. Rapid realist review of first contact physiotherapists to determine programme theories. A mixed-method case study evaluation of 46 general practices across the United Kingdom, grouped as three service delivery models: General practitioner: general practitioner-led models of care (no first contact physiotherapists). First-contact physiotherapists standard provision: standard first-contact physiotherapist-led model of care. First-contact physiotherapists with additional qualifications: first-contact physiotherapists with additional qualifications to enable them to inject and/or prescribe.

Setting

United Kingdom general practice.

Participants

A total of 46 sites participated in the case study evaluation and 426 patients were recruited; 80 staff and patients were interviewed.

Main outcome measures

Short Form 36 physical outcome component score and costs of treatment.

Results

No statistically significant difference in the primary outcome Short Form 36 physical component score measure at 6-month primary end point between general practitioner-led, first-contact physiotherapist standard provision and first-contact physiotherapist with additional qualifications models of care. A greater number of patients who had first-contact physiotherapist standard provision (72.4%) and first-contact physiotherapist with additional qualifications (66.4%) showed an improvement at 3 months compared with general practitioner-led care (54.7%). No statistically significant differences were found between the study arms in other secondary outcome measures, including the EuroQol-5 Dimensions, five-level version. Some 6.3% of participants were lost to follow-up at 3 months; a further 1.9% were lost to follow-up after 3 months and before 6 months. Service-use analysis data were available for 348 participants (81.7%) at 6 months. Inspecting the entire 6 months of the study, a statistically significant difference in total cost was seen between the three service models, irrespective of whether inpatient costs were included or excluded from the calculation. In both instances, the general practitioner service model was found to be significantly costlier, with a median total cost of £105.50 versus £41.00 for first-contact physiotherapist standard provision and £44.00 for first-contact physiotherapists with additional qualifications. Base-case analysis used band 7 for first-contact physiotherapist groups. A sensitivity analysis was undertaken at band 8a for first-contact physiotherapists with additional qualifications; the general practitioner-led model of care remained significantly costlier. Qualitative investigation highlighted key issues to support implementation: understanding role remit, integrating and supporting staff including full information technology access and extended appointment times.

Limitations

Services were significantly impacted by COVID-19 treatment restrictions, and recruitment was hampered by additional pressures in primary care. A further limitation was the lack of diversity within the sample.

Conclusions

First-contact physiotherapists and general practitioner models of care are equally clinically effective for people with musculoskeletal disorders. Analysis showed the general practitioner-led model of care is costlier than both the first-contact physiotherapist standard provision and first-contact physiotherapist with additional qualifications models. Implementation is supported by raising awareness of the first-contact physiotherapist role, retention of extended appointment times, and employment models that provide first-contact physiotherapists with professional support.

Future research

Determining whether shifting workforce impacts physiotherapy provision and outcomes across the musculoskeletal pathway.

First contact physiotherapy: an evaluation of clinical effectiveness and costs

BACKGROUND

First contact physiotherapy practitioners (FCPPs) are embedded within general practice, providing expert assessment, diagnosis, and management plans for patients with musculoskeletal disorders (MSKDs), without the prior need for GP consultation.

AIM

To determine the clinical effectiveness and costs of FCPP models compared with GP-led models of care.

DESIGN AND SETTING

Multiple site case-study design of general practices in the UK.

METHOD

General practice sites were recruited representing the following three models: 1) GP-led care; 2) FCPPs who could not prescribe or inject (FCPPs-standard [St]); and 3) FCPPs who could prescribe and/or inject (FCPPs-additional qualifications [AQ]). Patient participants from each site completed outcome data at baseline, 3 months, and 6 months. The primary outcome was the SF-36 Physical Component Summary (PCS) score. Healthcare usage was collected for 6 months.

RESULTS

In total, 426 adults were recruited from 46 practices across the UK. Non-inferiority analysis showed no significant difference in physical function (SF-36 PCS) across all three arms at 6 months (P = 0.667). At 3 months, a significant difference in numbers improving was seen between arms: 54.7% (n = 47) GP consultees, 72.4% (n = 71) FCPP-St, and 66.4% (n = 101) FCPP-AQ (P = 0.037). No safety issues were identified. Following initial consultation, a greater proportion of patients received medication (including opioids) in the GP-led arm (44.7%, n = 42), compared with FCPP-St (18.4%, n = 21) and FCPP-AQ (24.7%, n = 40) (P<0.001). NHS costs (initial consultation and over 6-month follow-up) were significantly higher in the GP-led model (median £105.5 per patient) versus FCPP-St (£41.0 per patient) and FCPP-AQ (£44.0 per patient) (P<0.001).

CONCLUSION

FCPP-led models of care provide safe, clinically effective patient management, with cost-benefits and reduced opioid use in this cohort.

Identifying physical therapists' attitudes, beliefs, and barriers toward diagnostic imaging referral: a mixed-methods study

OBJECTIVE

Ten states, including the District of Columbia, have laws that currently permit physical therapists (PTs) to directly order diagnostic imaging (DI) in the United States. Military and civilian PTs order DI judiciously and appropriately demonstrating optimal patient outcomes and satisfaction when compared to other medical professionals. However, no studies have explored perceived attitudes, beliefs, and barriers to PT DI referral specific to North Dakota (ND). Therefore, the purpose of this mixed-methods study was to identify ND PTs' attitudes, beliefs, and barriers toward DI referral.

METHODS

A total of 147 participants completed an online survey with a subset of 17 participants agreeing to an interview. Frequency counts of demographic data and perceived barriers were completed. A binary logistic regression was run on demographic data. One-on-one interviews were conducted with a thematic coding process completed within a qualitative analysis.

RESULTS

Seventy-four percent of PTs reported not currently referring for DI, although 71% felt that it would improve their patient outcomes. PTs with post-professional training (OR = 4.59), a doctorate degree (OR = 3.84), practicing in an orthopaedic or sports setting (OR = 3.55), and practicing within an urban setting of ND (OR = 3.01) were more likely to refer for DI. The main barriers identified in the survey included: (1) the logistics of performing a DI referral, (2) DI referrals only privileged to other medical providers, (3) provider/work relationship dynamics, (4) the cost of continuing education (CE), (5) and the inability to identify CE. One-on-one interviews further identified five main themes related to DI referral.

DISCUSSION/CONCLUSION

Several barriers identified resulted in 74.1% of PTs not directly referring for DI, although certain characteristics (post-professional training, doctorate degree, orthopaedic/sports setting, practicing in an urban area in ND) were more likely to refer for DI. This study may help improve future adoption and implementation of DI referral in current and future states.

Regional variation in low-value musculoskeletal surgery: a nationwide study from the Finnish Care Register

BACKGROUND AND PURPOSE

Healthcare systems globally are grappling with resource constraints and rising costs. Concerns have been raised about "low-value" care, which consumes healthcare resources without benefiting patients. We aimed to examine regional differences in common low-value musculoskeletal surgeries in Finland and explore explanatory factors behind the variation.

METHODS

Using data from the Finnish Care Register for Health Care, surgeries conducted from 2006-2007 compared with 2020-2021 were analyzed across 20 hospital districts. Selected surgeries (acromioplasty, rotator cuff repair, partial meniscectomy, wrist arthroscopy, ankle arthroscopy, and distal radius fracture fixation) were categorized based on NOMESCO procedure codes, and incidence rates in older populations were calculated based on population size derived from Statistics Finland.

RESULTS

We found substantial regional disparities in low-value surgeries. The incidence rates were higher in hospitals with high historical incidence rates and smaller population sizes, suggesting that the uptake of evidence is slower in small non-academic hospitals.

CONCLUSION

The incidence of low-value surgery is declining but regional differences remain large. It is unlikely that regional variation in disease incidence explains such large variation in low-value surgery. Instead, local treatment culture seems to be the driving force behind low-value surgery, and the practices seem to be more entrenched in small hospitals.

Do Maladaptive Imaging Beliefs Predict Self-Reported Pain Interference and Physical Function in Patients With Musculoskeletal Disorders?

OBJECTIVE: To determine if maladaptive imaging beliefs correlated with, and predicted pain interference and physical function outcomes in people with musculoskeletal pain disorders. DESIGN: A prospective cohort study of patients with musculoskeletal disorders receiving outpatient physical therapy from April 2022 to August 2023. METHODS: Four questions about imaging were asked to assess maladaptive beliefs, the need to rule out serious conditions, guide treatment, determine diagnosis, and validate symptoms. Correlations with beliefs and outcomes were assessed using Kendall's tau rank and Spearman's rho correlation coefficients. Generalized linear models determined if these beliefs predicted outcomes at baseline and 6 weeks. RESULTS: The cohort included 152 participants (mean [standard deviation] age: 56.13 [15.13]; 32.2% male). Maladaptive imaging beliefs correlated positively with pain interference and negatively with physical function. The need to rule out serious conditions and validate symptoms correlated with pain interference (range: τb = 0.17, 0.20; P = .003, .0121) and physical function (range: ρ = -0.22, -0.22; P = .006, .008). All but 1 belief correlated with pain interference (range: τb = 0.19, 0.24; P<.001, .004) and physical function (range: ρ = -0.26, -0.21; P = .001, .009) at 6 weeks. Each additional belief slightly increased pain interference at 6 weeks (β = 0.01; 95% CI: 0.001, 0.03; P = .04) and lowered physical function at both baseline (β = -0.97; 95% CI: -1.66, -0.28; P = .01) and 6 weeks (β = -0.76; 95% CI: -1.37, -0.15; P = .02). CONCLUSION: Maladaptive imaging beliefs were significantly (albeit weakly) correlated with pain and physical function. Each additional maladaptive imaging belief increased pain interference at 6 weeks and lowered physical function at baseline and 6 weeks. Beliefs about the necessity of imaging to properly manage musculoskeletal disorders may influence outcomes. J Orthop Sports Phys Ther 2024;54(9):1-10. Epub 5 July 2024. doi:10.2519/jospt.2024.12625.

Level of diagnostic agreement in musculoskeletal shoulder diagnosis between remote and face-to-face consultations: A retrospective service evaluation

Background and Aims

To determine the level of diagnostic agreement between remote and face-to-face consultation in assessing shoulder complaints.

Methods

A retrospective service evaluation with three groups of patient data; those assessed only face-to-face (group 1), remotely then face-to-face (group 2), remotely only (group 3). Patient data were extracted from 6 secondary care shoulder Advanced Physiotherapy Practitioner's (APPs) records, covering six sites. Three-hundred-and-fifty-nine sets of patient data were included in the final evaluation. The main outcome measure was the percentage of agreement between diagnosis at initial and follow-up consultation, when assessed by APPs across the three groups. A Pearson χ 2 test was used to assess the relationship between the method of consultation and the level of diagnostic agreement. Diagnoses were categorized as either the same, similar, or different by an independent APP. Secondary outcome measures investigated whether age or the length of time between appointments had any effect in determining the level of diagnostic concordance.

Results

There was exact agreement of 77.05% and 85.52% for groups 1 and 3, respectively, compared with 34.93% for patient data in group 2. Similar clinical impressions across both initial and follow-up were seen 16.39% of the time in group 1, 7.24% of the time in group 3, and 36.99% in group 2. Lastly, the percentage of times a diagnosis was changed between initial and review appointments occurred in only 6.56% of group 1 contacts, 7.24% of group 3 contacts, but 28.08% of the time in group 2.

Conclusion

There was a large mismatch in the diagnosis of musculoskeletal shoulder complaints, when patients are initially assessed remotely and then followed-up in-person. This has implications for the future provision of shoulder assessment in physiotherapy.

Low-value MRI of the knee in Norway: a register-based study to identify the proportion of potentially low-value MRIs and estimate the related costs

OBJECTIVES

The objective of this study is to investigate the proportion of potentially low-value knee MRI in Norway and to provide an estimate of the related costs.

DESIGN

Register study based on conditional data extraction and analysis of data from Control and Reimbursement of Healthcare Claims registry in Norway.

SETTING

MRI in public specialist healthcare with universal health coverage (Norway).

PARTICIPANTS

48 212 MRIs for 41 456 unique patients and 45 946 reimbursement claims.

OUTCOME MEASURES

Proportion of MRIs of the knee that (1) did not have a relevant tentative diagnosis prior to the knee MRI, (2) did not have a relevant alternative image of the knee before the MRI or (3) did not have a relevant code from the specialist care within 6 months after the MRI, and those that had combinations of 1, 2 and 3. Estimated costs for those that had combinations of 1, 2 and 3.

RESULTS

Very few patients (6.4%) had a relevant diagnosis code or prior imaging examination when having the MRI and only 14.6% got a knee-related diagnosis code from the specialist care within 6 months after the MRI. 21.8% of the patients had knee X-ray, CT or ultrasound within 6 months before the MRI. Between 58% and 85% of patients having knee MRIs in Norway have no relevant examinations or diagnoses six months prior to or after the MRI examination. These examinations are unlikely to benefit patients and they correspond to between 24 108 and 35 416 MRIs at a cost of €6.7-€9.8 million per year.

CONCLUSION

A substantial proportion of MRIs of the knee in Norway have no relevant examinations or diagnoses before or after the MRI and are potentially of low value. Reducing low-value MRIs could free resources for high-value imaging, reduce waiting times, improve the quality of care and increase patient safety and professional integrity.

Cost of chiropractic versus medical management of adults with spine-related musculoskeletal pain: a systematic review

BACKGROUND

The cost of spine-related pain in the United States is estimated at $134.5 billion. Spinal pain patients have multiple options when choosing healthcare providers, resulting in variable costs. Escalation of costs occurs when downstream costs are added to episode costs of care. The purpose of this review was to compare costs of chiropractic and medical management of patients with spine-related pain.

METHODS

A Medline search was conducted from inception through October 31, 2022, for cost data on U.S. adults treated for spine-related pain. The search included economic studies, randomized controlled trials and observational studies. All studies were independently evaluated for quality and risk of bias by 3 investigators and data extraction was performed by 3 investigators.

RESULTS

The literature search found 2256 citations, of which 93 full-text articles were screened for eligibility. Forty-four studies were included in the review, including 26 cohort studies, 17 cost studies and 1 randomized controlled trial. All included studies were rated as high or acceptable quality. Spinal pain patients who consulted chiropractors as first providers needed fewer opioid prescriptions, surgeries, hospitalizations, emergency department visits, specialist referrals and injection procedures.

CONCLUSION

Patients with spine-related musculoskeletal pain who consulted a chiropractor as their initial provider incurred substantially decreased downstream healthcare services and associated costs, resulting in lower overall healthcare costs compared with medical management. The included studies were limited to mostly retrospective cohorts of large databases. Given the consistency of outcomes reported, further investigation with higher-level designs is warranted.

Irish general practitioner (GP) perspectives on impact of direct access radiology on patient care in the community: results from a mixed-methods study

BACKGROUND

Since winter 2020/21, general practitioners (GPs) in the Republic of Ireland (RoI) have been granted access to diagnostic imaging studies on a new publicly funded pathway, expediting access to services previously obtained via hospital-based doctors.

AIMS

Outline GP perspectives on imaging studies obtained via the new "GP Access to Community Diagnostics" initiative.

METHODS

A mixed-methods design was employed. Referrals over the first six months of 2019 and 2021 were collated by a private imaging provider, and a randomly selected subset of 2021 studies (maximum 30 referrals per GP) was returned to participating GPs to provide detail on the impact on each patient's care. In-depth qualitative interviews were also conducted with participating GPs.

RESULTS

Eleven GPs supplied detailed information on 81 studies organized through the new initiative. GPs reported that the initiative had led to a large proportion of cases being managed solely in general practice, with an 81% reduction in referrals to acute hospital settings and a 58% reduction in referrals to secondary care clinics. GPs felt imaging studies improved patient care in 86% of cases and increased GP workload in 58% of cases. GP qualitative interviews revealed four key themes: improved patient care, increased GP workload, reduction in hospital referrals, and opinions on ongoing management of such initiatives, including guidelines.

CONCLUSIONS

GPs felt enhancing access to diagnostics improved patient care by expediting diagnosis, decision-making, and treatment and by reducing hospital referrals. GPs were generally positive about the initiative and made some suggestions on future management of the initiative.

Diagnostic testing in children: A qualitative study of pediatricians' considerations

AIMS AND OBJECTIVES

Studies in adult medicine have shown that physicians base testing decisions on the patient's clinical condition but also consider other factors, including local practice or patient expectations. In pediatrics, physicians and parents jointly decide on behalf of a (young) child. This might demand more explicit and more complex deliberations, with sometimes conflicting interests. We explored pediatricians' considerations in diagnostic test ordering and the factors that influence their deliberation.

METHOD

We performed in-depth, semistructured interviews with a purposively selected heterogeneous sample of 20 Dutch pediatricians. We analyzed transcribed interviews inductively using a constant comparative approach, and clustered data across interviews to derive common themes.

RESULTS

Pediatricians perceived test-related burden in children higher compared with adults, and reported that avoiding an unjustified burden causes them to be more restrictive and deliberate in test ordering. They felt conflicted when parents desired testing or when guidelines recommended diagnostic tests pediatricians perceived as unnecessary. When parents demanded testing, they would explore parental concern, educate parents about harms and alternative explanations of symptoms, and advocate watchful waiting. Yet they reported sometimes performing tests to appease parents or to comply with guidelines, because of feared personal consequences in the case of adverse outcomes.

CONCLUSION

We obtained an overview of the considerations that are weighed in pediatric test decisions. The comparatively strong focus on prevention of harm motivates pediatricians to critically appraise the added value of testing and drivers of low-value testing. Pediatricians' relatively restrictive approach to testing could provide an example for other disciplines. Improved guidelines and physician and patient education could help to withstand the perceived pressure to test.

The lived experiences of musculoskeletal physiotherapists managing patient expectations for diagnostic imaging: A qualitative study using a phenomenological analysis

OBJECTIVES

Unnecessary diagnostic imaging for musculoskeletal presentations is a pervasive phenomenon, placing a substantial weight on healthcare resources. Their overuse can lead to iatrogenic consequences associated with overdiagnosis and overtreatment. Factors which contribute to inappropriate imaging are multifactorial. Clinician-patient beliefs, behaviours, and expectations have been identified as central drivers. Physiotherapists play an important role in the utilisation of diagnostic imaging for musculoskeletal presentations throughout healthcare settings. This study aims to explore the lived experiences of physiotherapists managing patient expectations for diagnostic imaging.

DESIGN

A qualitative study using an interpretative phenomenological analysis. Five participants were purposefully recruited and took part in semi-structured individual interviews.

RESULTS

The central themes identified were expectations for diagnostic imaging, managing expectations, communicating imaging findings, imaging as a therapeutic tool, and risk and uncertainty.

CONCLUSION

The findings from this study gives new insights into how musculoskeletal physiotherapists manage expectations for diagnostic imaging, the associated complexities, and the challenges encountered.

Management of acute non-specific low back pain in the emergency department: do emergency physicians follow the guidelines? Results of a cross-sectional survey

OBJECTIVES

Clinical guidelines for acute non-specific low back pain (LBP) recommend avoiding imaging studies or invasive treatments and to advise patients to stay active. The aim of this study was to evaluate the management of acute non-specific LBP in the emergency departments (ED).

SETTING

We invited all department chiefs of Swiss EDs and their physician staff to participate in a web-based survey using two clinical case vignettes of patients with acute non-specific LBP presenting to an ED. In both cases, no neurological deficits or red flags were present. Guideline adherence and low-value care was defined based on current guideline recommendations.

RESULTS

In total, 263 ED physicians completed at least one vignette, while 212 completed both vignettes (43% residents, 32% senior/attending physicians and 24% chief physicians). MRI was considered in 31% in vignette 1 and 65% in vignette 2. For pain management, non-steroidal anti-inflammatory drugs, paracetamol and metamizole were mostly used. A substantial proportion of ED physicians considered treatments with questionable benefit and/or increased risk for adverse events such as oral steroids (vignette 1, 12% and vignette 2, 19%), muscle relaxants (33% and 38%), long-acting strong opioids (25% and 33%) and spinal injections (22% and 43%). Although guidelines recommend staying active, 72% and 67% of ED physicians recommended activity restrictions.

CONCLUSION

Management of acute non-specific LBP in the ED was not in agreement with current guideline recommendations in a substantial proportion of ED physicians. Overuse of imaging studies, the use of long-acting opioids and muscle relaxants, as well as recommendations for activity and work restrictions were prevalent and may potentially be harmful.

Magnetic Resonance Imaging in the Year Prior to Total Knee Arthroplasty: A Potential Overutilization of Healthcare Resources

BACKGROUND

Total knee arthroplasty (TKA) is a common procedure for late-stage degenerative changes, a situation for which magnetic resonance imaging (MRI) is typically not considered useful. In an era attempting to contain healthcare expenditures, the rate, timing, and predictors for MRI before TKA were assessed in a large, national, administrative data set.

METHODS

The 2010 to Q3 2020 MKnee PearlDiver data set was used to identify patients undergoing TKA for osteoarthritis. Those with lower extremity MRI for knee indications within 1 year before TKA were then defined. Patient age, sex, Elixhauser Comorbidity Index, region in the country, and insurance plan were characterized. Predictors of having had an MRI were assessed by univariate and multivariate analyses. The costs and timing of the obtained MRIs were also assessed.

RESULTS

Of 731,066 TKAs, MRI was obtained within 1 year prior for 56,180 (7.68%) with 28,963 (51.9%) within the 3 months of TKA. Independent predictors of having had an MRI included younger age (odds ratio [OR], 0.74 per decade increase), female sex (OR, 1.10), higher Elixhauser Comorbidity Index (OR, 1.15), region of the country (relative to South, Northeast OR, 1.08, West OR, 1.22, Midwest OR, 1.36), and insurance (relative to Medicare, Medicaid OR, 1.36 and Commercial OR, 1.35) with P < 0.0001 for each. The total cost of MRIs among patients who received a TKA is $44,686,308.

CONCLUSION

Noting that TKA is typically done for advanced degenerative changes, MRI should rarely be indicated in the preoperative period for this procedure. Nonetheless, this study found that MRI was done within the year before TKA for 7.68% of the study cohort. In an era striving for evidence-based medicine, the almost $45 million dollars spent on MRI in the year before TKA may represent overutilization.

Impact of enhancing GP access to diagnostic imaging: A scoping review

BACKGROUND

Direct access to diagnostic imaging in General Practice provides an avenue to reduce referrals to hospital-based specialities and emergency departments, and to ensure timely diagnosis. Enhanced GP access to radiology imaging could potentially reduce hospital referrals, hospital admissions, enhance patient care, and improve disease outcomes. This scoping review aims to demonstrate the value of direct access to diagnostic imaging in General Practice and how it has impacted on healthcare delivery and patient care.

METHODS

A search was conducted of 'PubMed', 'Cochrane Library', 'Embase' and 'Google Scholar' for papers published between 2012-2022 using Arksey and O'Malley's scoping review framework. The search process was guided by the PRISMA extension for Scoping Reviews checklist (PRISMA-ScR).

RESULTS

Twenty-three papers were included. The studies spanned numerous geographical locations (most commonly UK, Denmark, and Netherlands), encompassing several study designs (most commonly cohort studies, randomised controlled trials and observational studies), and a range of populations and sample sizes. Key outcomes reported included the level of access to imaging serves, the feasibility and cost effectiveness of direct access interventions, GP and patient satisfaction with direct access initiatives, and intervention related scan waiting times and referral process.

CONCLUSION

Direct access to imaging for GPs can have many benefits for healthcare service delivery, patient care, and the wider healthcare ecosystem. GP focused direct access initiatives should therefore be considered as a desirable and viable health policy directive. Further research is needed to more closely examine the impacts that access to imaging studies have on health system operations, especially those in General Practice. Research examining the impacts of access to multiple imaging modalities is also warranted.

An economic impact of incorrect referrals for MRI and CT scans: A retrospective analysis

Background and Aims

Up to date, no research on the economic efficacy of diagnostic modalities, such as magnetic resonance imaging (MRI) and computerized tomography (CT), has been done in Central Asia. The aim of this study was to analyse the inappropriate appointments of MRI and CT scanning procedures in Kazakhstan.

Methods

We used the imaging diagnostic reports and medical records from 9725 planned outpatient CT and MRI exams performed in two major hospitals in Almaty. The study period was for the period 2014-2019. The independent experts-radiologists evaluated the MRI and CT exams for validity using the ACR® compliance standards and RCR recommendations.

Results

The results showed that the combined costs of MRI and CT scans increased by $17.982 between 2014 ($22.537) and 2019 ($40.519), p = 0.002. The highest rate of MRI examinations was observed in 2019, with a rate of 6.9 per 10,000 people. It was determined that in 2019 the highest rate for men who undertook CT was equal to 12.4 per 10,000 people, while for women it was equivalent to 5.7 per 10,000 patients. The majority of non-corresponding imaging examinations (n = 1304) were referred for MRI and CT scans by general practitioners. We detected the irrational referrals for head and neck radiological examinations in n = 178 (13.7%) cases, and the abdominal cavity checks in n = 249 (19.1%) cases (p = 0.001). The main portion of erroneously unreasonable referrals for examination of the abdominal organs was made by surgeons in n = 43 (3.3%) cases.

Conclusion

The findings indicated an increase in the number of referrals for unnecessary CT and MRI tests over the research period (2014-2019). It had a substantial impact on the rise in healthcare system expenses. The results demonstrate the need for the education of GPs and improving the approaches for diagnostics.

The use of low-value imaging: the role of referral practice and access to imaging services in a representative area of Norway

BACKGROUND

Even though imaging is essential to modern medicine, some examinations are of low value as they do not lead to any change in the management of the patient. The Choosing Wisely (CW) campaign aims to reduce the use of such services. In the Norwegian version of CW, specific magnetic resonance imaging (MRI) of the head, lower back, and knee are amongst others identified as potential low-value examinations. However, referral practice and access to imaging may drive low-value utilisation. By using registry data from 2019 and descriptive analysis, this study aimed to examine the role of referral practice and access to imaging on the use of specific CW-examinations in one representative area in Norway.

RESULTS

A total of 237,554 examinations were performed by four public and two private imaging facilities located within the area. Forty-two percent (19,210/45,289) of all MRI examinations were related to CW. Private imaging centres performed most of the CW-imaging. A total of 3700 referrers were identified, and 2.3% were identified as "high-referrers," accounting for 33% of all CW-examinations. Referrers' experience did not influence imaging utilisation. A subset of referrers ("super-referrers," 0.5%) accounted for 10% of CW-examinations. Distance to service had no impact on the use of CW-examinations.

CONCLUSIONS

This study provides valuable insight into the use of imaging and referral practice in one representative area in Norway. A great variation in referral practice was observed. Therefore, targeting referrers with high referral rates may be a promising strategy for reducing the use of low-value imaging.

Can American Orthopaedic Foot and Ankle Society (AOFAS) score prevent unnecessary MRI in isolated ankle ligament injuries?

INTRODUCTION AND OBJECTIVE

Ankle injuries are the most common musculoskeletal injuries. Its incidence is also high among sports injuries. Direct X-ray, ultrasound and MRI can be requested after the history and physical examination in the patient who presents with ankle ligament injury. Some classifications are used for requesting direct X-ray after ankle injury. Since clear limits are not specified in the literature for MRI, the rate of unnecessary MRI examinations is high. We argue that the decision can be made according to the AOFAS score to be checked before MR is requested, and thus unnecessary MR requests can be reduced.

MATERIAL AND METHOD

Ankle MRI images of patients who underwent ankle MRI due to ankle trauma between January 2018 and December 2020 were scanned. 328 patients who met the criteria were included in the study. Patients with AOFAS scores in their outpatient clinic records were identified. AOFAS scores of patients with at least one ligament injury and those with normal MR images were statistically compared. Sensitivity and specificity were determined for the AOFAS score using ROC analysis.

RESULTS

Patients with ligament damage as a result of MRI examination were 21.3% (n=70), and patients without any ligament damage were 78.7% (n=258). There was a statistically significant difference in terms of AOFAS between the group with ligament damage and the group without ligament damage (p&lt; 0.05). In the ROC analysis, the AOFAS threshold value for MR request was determined as 80.5 (84.3% sensitivity and 72.3% specificity). Based on the determined threshold value, 73 patients who had unnecessary MRI would have been eliminated, thus reducing the number of MRIs by 42.6%.

CONCLUSION

The AOFAS scores of patients with ligament damage were statistically significantly lower than those of patients without ligament pathology. Unnecessary MRI can be significantly prevented by using the AOFAS score in ankle traumas without bone fractures.

Assessment and monitoring of Achilles tendinopathy in clinical practice: a qualitative descriptive exploration of the barriers clinicians face

Our primary objective was to explore the barriers preventing clinicians from implementing what they think is ideal practice as it relates to using tools to aid diagnosis and monitor progress in mid-portion Achilles tendinopathy. Our secondary objectives were to describe the assessments employed by clinicians in their own practice to aid with (a) diagnosis and (b) monitoring progress in Achilles tendinopathy and explore the outcome measure domains clinicians believe to be the most and least important when managing patients with Achilles tendinopathy. We employed a qualitative descriptive study design. Thirteen participants (eight female, five male) from across Australia, consisting of two junior physiotherapists, five senior physiotherapists working in private practice, four senior physiotherapists working within elite sports organisations and two sport and exercise medicine doctors, were included and one-on-one interviews were performed. Audio was transcribed then entered into NVivo for coding and analysis. Four main themes were perceived as barriers to implementing ideal practice of assessment and monitoring in people with Achilles tendinopathy: financial constraints, time constraints, access to equipment and patient symptom severity. Assessments related to function, pain on loading, pain over a specified time frame and palpation are commonly used to assist diagnosis. Assessments related to disability, pain on loading, pain over a specified time frame and physical function capacity are used to monitor progress over time. Furthermore, pain on loading and pain over a specified time frame were considered the most important outcome measure domains for assisting diagnosis whereas pain on loading, patient rating of the condition and physical function capacity were the most important outcome measure domains for monitoring progress. A number of barriers exist that prevent clinicians from implementing what they view as ideal assessment and monitoring for Achilles tendinopathy. These barriers should be considered when developing new assessments and in clinical practice recommendations.

Reducing low-value radiological services in Norway -a qualitative multi-professional study on measures and facilitators for change

BACKGROUND

Overuse, underuse, and significant variation in the utilisation of radiological services are well documented in the literature. Several radiological examinations are identified as low-value examinations as they do not lead to a change in diagnosis or course of treatment. Even so, such examinations are frequently performed. Many measures for reducing low-value imaging have been carried out with variable outcomes. While there is little evidence as to why some measures work and others do not, adjusting to the context seems important for success. The objective of this study was to investigate which measures stakeholders consider appropriate for reducing the use of low-value imaging and what it takes to make them work.

METHODS

Semi-structured interviews were conducted among radiographers, radiologists, radiological department managers, hospital clinicians, general practitioners, and health government/authorities' representatives. The interview guide covered two broad areas: Experience with low-value services, and possible future measures deemed appropriate for reducing low-value services. Data were analysed in line with a qualitative framework analysis.

RESULTS

The analysis included information from 27 participants. All participants acknowledged that low-value imaging was a problem, but few had very specific suggestions on reducing this in practice. Suggested measures were to stop referrals from being sent, provide support in assessing referrals, or change the healthcare system. Identified facilitators were categorised as management and resources, evidence, and experienced value. In general, appropriate measures should be practical, well-founded, and valuable.

CONCLUSIONS

This study provides insight into various stakeholders' perceptions of suitable interventions to reduce low-value imaging. While many measures for reducing low-value imaging are available, contextual sensitivity is crucial to make them work.

Unraveling Negative Expectations and Nocebo-Related Effects in Musculoskeletal Pain

This Perspective adapts the ViolEx Model, a framework validated in several clinical conditions, to better understand the role of expectations in the recovery and/or maintenance of musculoskeletal (MSK) pain. Here, particular attention is given to the condition in which dysfunctional expectations are maintained despite no longer being supported by confirmatory evidence (i.e., belief-lifting the arm leads to permanent tendon damage; evidence-after the patient lifts the arm no tendon damage occurs). While the ViolEx Model suggests that cognitive immunization strategies are responsible for the maintenance of dysfunctional expectations, we suggest that such phenomenon can also be understood from a Bayesian Brain perspective, according to which the level of precision of the priors (i.e., expectations) is the determinant factor accounting for the extent of priors' updating (i.e., we merge the two frameworks, suggesting that highly precise prior can lead to cognitive immunization responses). Importantly, this Perspective translates the theory behind these two frameworks into clinical suggestions. Precisely, it is argued that different strategies should be implemented when treating MSK pain patients, depending on the nature of their expectations (i.e., positive or negative and the level of their precision).

Characteristics and Effectiveness of Interventions That Target the Reporting, Communication, or Clinical Interpretation of Lumbar Imaging Findings: A Systematic Review

BACKGROUND

Patients and clinicians may misinterpret the clinical importance of imaging findings in patients with low back pain, leading to potential harm related to overdiagnosis.

PURPOSE

Our aims were to qualitatively summarize the characteristics of tested interventions that target the reporting, communication, or clinical interpretation of lumbar imaging findings and determine whether interventions are effective in improving low back pain-related health outcomes, health care use, or health care costs.

DATA SOURCES

PubMed, MEDLINE, CINAHL, EMBASE, PsycINFO, and the Cochrane Library were searched from inception to October 20, 2021.

STUDY SELECTION

The search retrieved 4394 articles, nine articles (seven studies) met the inclusion criteria to summarize intervention characteristics. Five of these studies had an adequate design for evaluating intervention effectiveness.

DATA ANALYSES

Intervention characteristics were summarized using the Template for Intervention Description and Replication checklist. Effectiveness data were extracted from short, intermediate, and long-term follow-up points. Studies were assessed for risk of bias, and Grading of Recommendations Assessment, Development and Evaluation methodology was used to determine the certainty of the evidence.

DATA SYNTHESIS

Four studies investigated the insertion of prevalence information into imaging reports. Single studies investigated withholding diagnostic information, education, and reassurance. Moderate-quality evidence (from 1 study) suggests that inserting prevalence information into imaging reports probably does not change the overall health care use in the long-term but may reduce opioid prescribing.

LIMITATIONS

The available evidence is limited, and a meta-analysis was not possible.

CONCLUSIONS

Further work is required to develop and test interventions that target the reporting, communication, and clinical interpretation of lumbar imaging findings that may reduce overdiagnosis and improve the management of low back pain.

Effects of whole-body MRI on outpatient health service costs: a general-population prospective cohort study in Mecklenburg-Vorpommern, Germany

OBJECTIVE

Whole-body MRI (wb-MRI) is increasingly used in research and screening but little is known about the effects of incidental findings (IFs) on health service utilisation and costs. Such effects are particularly critical in an observational study. Our principal research question was therefore how participation in a wb-MRI examination with its resemblance to a population-based health screening is associated with outpatient service costs.

DESIGN

Prospective cohort study.

SETTING

General population Mecklenburg-Vorpommern, Germany.

PARTICIPANTS

Analyses included 5019 participants of the Study of Health in Pomerania with statutory health insurance data. 2969 took part in a wb-MRI examination in addition to a clinical examination programme that was administered to all participants. MRI non-participants served as a quasi-experimental control group with propensity score weighting to account for baseline differences.

PRIMARY AND SECONDARY OUTCOME MEASURES

Outpatient costs (total healthcare usage, primary care, specialist care, laboratory tests, imaging) during 24 months after the examination were retrieved from claims data. Two-part models were used to compute treatment effects.

RESULTS

In total, 1366 potentially relevant IFs were disclosed to 948 MRI participants (32% of all participants); most concerned masses and lesions (769 participants, 81%). Costs for outpatient care during the 2-year observation period amounted to an average of €2547 (95% CI 2424 to 2671) for MRI non-participants and to €2839 (95% CI 2741 to 2936) for MRI participants, indicating an increase of €295 (95% CI 134 to 456) per participant which corresponds to 11.6% (95% CI 5.2% to 17.9%). The cost increase was sustained rather than being a short-term spike. Imaging and specialist care related costs were the main contributors to the increase in costs.

CONCLUSIONS

Communicated findings from population-based wb-MRI substantially impacted health service utilisation and costs. This introduced bias into the natural course of healthcare utilisation and should be taken care for in any longitudinal analyses.
