Diagnostic labels and advice for rotator cuff disease influence perceived need for shoulder surgery: an online randomised experiment

Negative expectations and related nocebo effects in shoulder pain: a perspective for clinicians and researchers

The nocebo effect, a phenomenon wherein negative expectations can worsen symptoms, is increasingly acknowledged within the context of musculoskeletal conditions. While experimental evidence has, to some extent, examined negative expectations in shoulder pain, their specific relationship with nocebo effects and their manifestation in clinical practice remains unexplored. In this perspective, clinicians and researchers are guided by first examining the psychobiology and neurophysiology underlying nocebo effects from a basic science standpoint, thereby equipping clinicians with a robust understanding of the phenomenon. What are considered the primary potential sources of nocebo effects in individuals with shoulder pain are then outlined - namely, diagnostic labels, diagnostic imaging and special tests, the medicalization of normality, and overtreatment. Practical clinical strategies are subsequently proposed to mitigate nocebo effects arising from these sources. Finally, the research implications for advancing the study of nocebo effects in people with shoulder pain are discussed. Overall, this perspective provides a comprehensive overview of the impact of negative expectations and associated nocebo effects on shoulder pain outcomes. By identifying potential sources of nocebo effects that may emerge in everyday clinical practice, guidance on mitigating related negative expectations in patients with shoulder pain is offered.

The effectiveness of education for people with shoulder pain: A systematic review

OBJECTIVES

To investigate the effectiveness of education for people with shoulder pain.

DESIGN

Systematic review LITERATURE SEARCH: We searched several databases (e.g. MEDLINE, EMBASE, CENTRAL, CINAHL) and trial registries from inception to May 25, 2023.

STUDY SELECTION CRITERIA

Randomised controlled trials investigating any education for people with shoulder pain.

DATA SYNTHESIS

Pain and disability were primary outcomes. The Physiotherapy Evidence Database (PEDro) scale was used to assess methodological quality. Meta-analysis was not appropriate due to heterogeneity.

RESULTS

We included 14 trials (8 had high methodological quality). The one trial on rotator-cuff related shoulder pain did not assess pain or disability but found best practice education (vs. structure-focused education) increased reassurance and intentions to stay active. The one trial on adhesive capsulitis found daily reminders, encouragement, and education about exercise via text did not improve pain and disability compared to no education. For post-operative shoulder pain, two (of four) trials found education reduced some measure of pain, but none found an effect on disability or any other outcomes. For 'shoulder complaints' (i.e. mixed or unclear diagnosis), no trials found education was more effective than home exercise or no education for improving pain or disability.

CONLUSION

Some forms of education appear to improve reassurance, treatment intentions, perceived treatment needs, recovery expectations, and knowledge, but their effect on pain and disability is unclear. High-quality trials are needed to resolve uncertainty surrounding the benefit of education for shoulder pain, particularly rotator-cuff related shoulder pain and adhesive capsulitis.

Patient education for the management of subacromial pain syndrome: A scoping review

OBJECTIVE

To identify the extent of the literature on patient education for subacromial pain syndrome (SAPS).

METHODS

A scoping review was conducted in accordance with PRISMA-ScR standards. Nine databases were searched until November 2022 to identify articles describing patient education interventions for the management of SAPS. Interventions were extracted and described according to the Template for intervention description and replication (TIDieR) checklist and the core sets for shoulder-related health conditions of the International Classification of Functioning, Disability and Health (ICF).

RESULTS

Sixty studies of various designs met the inclusion criteria, including thirty RCTs. Patient education was a primary intervention in seven of the included RCTs. In most of the educational interventions identified in the included studies, the descriptions did not adequately cover a majority of the TIDieR's checklist items. Patient education content was often mentioned and covered most, but not all, of the ICF core sets for shoulder disorders.

CONCLUSION

Available data in current literature on patient education interventions for SAPS is scarce and lacks description.

PRACTICE IMPLICATIONS

This study presents the content elements of patient education for the management of SAPS that are described in the literature and that clinicians could consider when treating individuals with SAPS.

The Influence of "Labels" for Neck Pain on Recovery Expectations Following a Motor Vehicle Crash: An Online-Randomized Vignette-Based Experiment

OBJECTIVES: To (1) investigate whether different labels for neck pain after a motor vehicle crash (MVC) influenced recovery expectations and management beliefs, (2) explore reasons for low recovery expectations and greater likelihood for lodging a claim, and (3) explore the moderating effect of neck pain history and sociodemographic characteristics. DESIGN: Online randomized experiment with nested qualitative content analysis. METHODS: We randomized 2229 participants from the general population (mean age: 46.7 ± 17.5 years; 72.4% females; 66% with previous or current neck pain; 10% with an MVC experience) to read 1 of 5 scenarios describing a patient with neck pain after an MVC, each was labeled as whiplash injury, whiplash-associated disorder, posttraumatic neck pain, neck pain, or neck strain. The primary outcome was recovery expectations, rated on a 0- to 10-point scale. RESULTS: Participants allocated to whiplash-associated disorder or neck pain had lower recovery expectations than those allocated to neck strain (adjusted mean difference [95% confidence interval]: -0.5 [-0.9 to -0.1] for both comparisons). Whiplash-associated disorder led to more recovery uncertainty, while neck pain led to greater doubt about the health care provider. Most secondary outcomes showed significant but small differences. Participants allocated to neck strain were less inclined to claim than those allocated to whiplash-associated disorder or whiplash injury due to less perceived need for financial support. Neck pain history moderated labeling effects on recovery expectations; household income moderated the claim intention. CONCLUSIONS: Labels for neck pain after an MVC influenced recovery expectations and management preferences. The clinical relevance of the small effects was unclear.

Use of a surgical referral algorithm within a standardized shoulder physical therapy program to assist clinical decision-making

PURPOSE

Determine (a) utility of a shoulder referral algorithm, (b) patients improving ≥15% on the Western Ontario Rotator Cuff(WORC) score with standardized Physical Therapy(PT) +home exercises, and (c) presenting characteristics among PT-Only, PT + Surgical Consult and Surgery participants.

MATERIALS AND METHODS

Prospective cohort study of patients 30-65 years old with shoulder pain. A standardized PT program assessed pain, ROM, strength and exercise tolerance (i.e., referral algorithm) at 2-, 6- and 12-weeks to determine if a surgical consultation might be beneficial. A blinded research assessor evaluated pain, ROM, strength and WORC score at 6-, 12-weeks and 6-months. The proportion improving WORC scores ≥15% and group differences were also evaluated.

RESULTS

32/128 (25%) participants underwent consultation with 16 (12.5%) undergoing surgery. WORC scores improved ≥15% by 12-weeks in most PT-Only/PT + Surgical Consult participants (n = 77[70%]) and was maintained at 6-months. Surgery participants used more NSAIDs (p = 0.01), injections (p = 0.002) and trended to higher opioid use (p = 0.06). PT + Surgical Consult/Surgery participants (n = 16/32; 50%) knew diagnostic imaging results more than PT-Only (n = 26; 31%) (p = 0.02). Surgery participants presented with worse pain, ROM, strength and WORC scores than PT-Only (p < 0.05).

CONCLUSIONS

The algorithm identified those with worse symptomology (25%), 50% of whom underwent surgery. WORC scores improved ≥15% in most participants (70%). Presenting characteristics were significantly worse between PT-Only and Surgery participants.

Perceptions of advice for acute low back pain: a content analysis of qualitative data collected in a randomised experiment

OBJECTIVES

To explore how people perceive three different forms of advice for acute low back pain (LBP).

DESIGN

Content analysis of qualitative data collected in a three-arm randomised experiment.

PARTICIPANTS

2200 participants with acute LBP (ie, pain duration for ≤6 weeks) were randomly assigned to receive three types of advice: guideline advice and guideline advice with the addition of either brief pain science or ergonomics messages.

PRIMARY AND SECONDARY OUTCOMES

After receiving the advice, participants answered two questions: 'If your health professional gave you this advice, how would it make you feel?' and 'If your health professional gave you this advice, what treatments (if any) do you think you would need?' Two researchers coded responses using deductive content analysis.

RESULTS

We analysed 4400 free-text responses from 2200 participants. There were little to no differences in participants' feelings, thoughts and expectations after receiving three types of advice for acute LBP. Participants most commonly expressed feeling positive about the advice (38%-35%), reassured (23%-22%) and empowered (10%-8%). Some expressed being unhappy or being frustrated with the advice (4%-3%). Participants most commonly thought they needed no treatment apart from staying active, followed by exercise and medication.

CONCLUSIONS

Guideline advice with or without the addition of brief pain science or ergonomics messages generated positive feelings, reassurance or a sense of empowerment in many people with acute LBP, with no difference between types of advice.

Education can reassure people with rotator cuff-related shoulder pain: a 3-arm, randomised, online experiment

ABSTRACT

We aimed to investigate the immediate effect of best practice education (with and without pain science messages) and structure-focused education on reassurance among people with rotator cuff-related shoulder pain. We conducted a 3-arm, parallel-group, randomised experiment. People with rotator cuff-related shoulder pain were randomised (1:1:1) to (1) best practice education (highlights that most shoulder pain is not serious or a good indicator of tissue damage and recommends simple self-management strategies); (2) best practice education plus pain science messages (which attempt to improve understanding of pain); and (3) structure-focused education (highlighting that structural changes are responsible for pain and should be targeted with treatment). Coprimary outcomes were self-reported reassurance that no serious condition is causing their pain and continuing with daily activities is safe. Secondary outcomes measured management intentions, credibility and relevance of the education, and similarity to previous education. Two thousand two hundred thirty-seven participants were randomised and provided primary outcome data. Best practice education increased reassurance that no serious condition is causing their pain (estimated mean effect 0.5 on a 0-10 scale, 95% confidence interval [CI] 0.2-0.7) and continuing with daily activities is safe (0.6, 95% CI 0.3-0.8) compared with structure-focused education . Adding pain science messages to best practice education slightly increased both measures of reassurance (0.2, 95% CI 0.0-0.4). Clinicians treating patients with rotator cuff-related shoulder pain should highlight that most shoulder pain is not serious or a good indicator of tissue damage and recommend simple self-management strategies. The benefit of adding pain science messages is small.

Adding Brief Pain Science or Ergonomics Messages to Guideline Advice Did Not Increase Feelings of Reassurance in People With Acute Low Back Pain: A Randomized Experiment

OBJECTIVE: To investigate the effects of adding pain science or ergonomics messages to guideline advice on feelings of reassurance and management intentions among people with acute low back pain (LBP). DESIGN: Three-arm parallel-group randomized experiment. METHODS: We recruited people with acute LBP (pain for ≤6 weeks) to participate in an online experiment. Participants were randomized at a 1:1:1 ratio to one of three groups: guideline advice alone or guideline advice with the addition of brief pain science or ergonomics messages. The intervention was delivered via prerecorded videos in all 3 groups. Coprimary outcomes were reassurance that (1) no serious condition is causing LBP and (2) continuing with daily activities is safe. Secondary outcomes were perceived risk of developing chronic pain, management intentions (bed rest, see a health professional, see a specialist, and imaging), credibility, and relevance of the advice in addressing the participant's concerns. RESULTS: Two thousand two hundred ninety-seven responses (99.3% of 2,313 randomized) were analyzed. Adding brief pain science or ergonomics messages to guideline advice did not change reassurance that LBP was not caused by serious disease. The addition of ergonomics advice provided worse reassurance that it is safe to continue with daily activities compared to guideline advice (mean difference [MD], -0.33; 95% CI: 0.13, 0.53). There was no difference between groups on management intentions. CONCLUSION: Adding pain science or ergonomics messages to guideline advice did not increase reassurance or change management intentions in people with acute LBP. Ergonomics messages may lead to reduced feelings of reassurance. J Orthop Sports Phys Ther 2023;53(12)1-11. Epub 26 September 2023. doi:10.2519/jospt.2023.12090.

How do people perceive different advice for rotator cuff disease? A content analysis of qualitative data collected in a randomised experiment

OBJECTIVES

To explore how people perceive different advice for rotator cuff disease in terms of words/feelings evoked by the advice and treatment needs.

SETTING

We performed a content analysis of qualitative data collected in a randomised experiment.

PARTICIPANTS

2028 people with shoulder pain read a vignette describing someone with rotator cuff disease and were randomised to: bursitis label plus guideline-based advice, bursitis label plus treatment recommendation, rotator cuff tear label plus guideline-based advice and rotator cuff tear label plus treatment recommendation. Guideline-based advice included encouragement to stay active and positive prognostic information. Treatment recommendation emphasised that treatment is needed for recovery.

PRIMARY AND SECONDARY OUTCOMES

Participants answered questions about: (1) words/feelings evoked by the advice; (2) treatments they feel are needed. Two researchers developed coding frameworks to analyse responses.

RESULTS

1981 (97% of 2039 randomised) responses for each question were analysed. Guideline-based advice (vs treatment recommendation) more often elicited words/feelings of reassurance, having a minor issue, trust in expertise and feeling dismissed, and treatment needs of rest, activity modification, medication, wait and see, exercise and normal movements. Treatment recommendation (vs guideline-based advice) more often elicited words/feelings of needing treatment/investigation, psychological distress and having a serious issue, and treatment needs of injections, surgery, investigations, and to see a doctor.

CONCLUSIONS

Words/feelings evoked by advice for rotator cuff disease and perceived treatment needs may explain why guideline-based advice reduces perceived need for unnecessary care compared to a treatment recommendation.

Should low-risk DCIS lose the cancer label? An evidence review

BACKGROUND

Population mammographic screening for breast cancer has led to large increases in the diagnosis and treatment of ductal carcinoma in situ (DCIS). Active surveillance has been proposed as a management strategy for low-risk DCIS to mitigate against potential overdiagnosis and overtreatment. However, clinicians and patients remain reluctant to choose active surveillance, even within a trial setting. Re-calibration of the diagnostic threshold for low-risk DCIS and/or use of a label that does not include the word 'cancer' might encourage the uptake of active surveillance and other conservative treatment options. We aimed to identify and collate relevant epidemiological evidence to inform further discussion on these ideas.

METHODS

We searched PubMed and EMBASE databases for low-risk DCIS studies in four categories: (1) natural history; (2) subclinical cancer found at autopsy; (3) diagnostic reproducibility (two or more pathologist interpretations at a single time point); and (4) diagnostic drift (two or more pathologist interpretations at different time points). Where we identified a pre-existing systematic review, the search was restricted to studies published after the inclusion period of the review. Two authors screened records, extracted data, and performed risk of bias assessment. We undertook a narrative synthesis of the included evidence within each category.

RESULTS

Natural History (n = 11): one systematic review and nine primary studies were included, but only five provided evidence on the prognosis of women with low-risk DCIS. These studies reported that women with low-risk DCIS had comparable outcomes whether or not they had surgery. The risk of invasive breast cancer in patients with low-risk DCIS ranged from 6.5% (7.5 years) to 10.8% (10 years). The risk of dying from breast cancer in patients with low-risk DCIS ranged from 1.2 to 2.2% (10 years). Subclinical cancer at autopsy (n = 1): one systematic review of 13 studies estimated the mean prevalence of subclinical in situ breast cancer to be 8.9%. Diagnostic reproducibility (n = 13): two systematic reviews and 11 primary studies found at most moderate agreement in differentiating low-grade DCIS from other diagnoses. Diagnostic drift: no studies found.

CONCLUSION

Epidemiological evidence supports consideration of relabelling and/or recalibrating diagnostic thresholds for low-risk DCIS. Such diagnostic changes would need agreement on the definition of low-risk DCIS and improved diagnostic reproducibility.
