Reframing pain: the power of individual and societal factors to enhance pain treatment

The effectiveness of analgesics can be increased if synergistic behavioural, psychological, and pharmacological interventions are provided within a supportive environment.

Effectiveness of a Web-Guided Self-Managed Telerehabilitation Program Enhanced with Outdoor Physical Activity on Physical Function, Physical Activity Levels and Pain in Patients with Knee Osteoarthritis: A Randomized Controlled Trial

Background: Telerehabilitation to guide self-management has been shown to be a feasible care strategy for knee osteoarthritis (KOA). The aim of this study was to explore the effectiveness of a blended web-based rehabilitation program enhanced with outdoor physical activity (BWR-OPA) and consultation versus an OPA (usual care) program in KOA patients. Methods: Forty-four KOA participants were prescribed to follow the programs five times/week for 6 weeks. The primary outcome was self-reported physical function, measured by the Knee Injury and Osteoarthritis Outcome Score (KOOS). The secondary outcomes were pain, PA, function (timed up-and-go (TUG) test, 30 s chair rise test (30 s CRT)), psychological functioning and QoL. Results: There was a significant difference between the groups' KOOSs for pain and symptom subscales at the 6- and 12-week post-intervention assessments compared to baseline (p < 0.005) favoring the BWR-OPA group. There was a superior improvement in PA in the BWR-OPA training group (p < 0.05). Statistical and clinical improvements were found (p < 0.001) with effect sizes over 2.0 for objective measures of function. Similar improvements were recorded over time (p < 0.005) at 12 weeks for QoL, KOOS subscales for ADL, QoL and sports/recreation and psychological functioning for both groups. Conclusions: A blended web-based self-managed care program with outdoor PA was superior in many respects to usual care in KOA participants.

Intravenous cangrelor use for neuroendovascular procedures: a two-center experience and updated systematic review

Background

The optimal antiplatelet therapy regimen for certain neuroendovascular procedures remains unclear. This study investigates the safety and feasibility of intravenous dose-adjusted cangrelor in patients undergoing acute neuroendovascular interventions.

Methods

We conducted a retrospective chart review of all consecutive patients on intravenous cangrelor for neuroendovascular procedures between September 1, 2020, and March 13, 2022. We also conducted an updated systematic review and meta-analysis using PubMed, Scopus, Web of Science, Embase and the Cochrane Library up to February 22, 2023.

Results

In our cohort, a total of 76 patients were included [mean age (years): 57.2 ± 18.2, males: 39 (51.3), Black: 49 (64.5)]. Cangrelor was most used for embolization and intracranial stent placement (n = 24, 32%). Approximately 44% of our patients had a favorable outcome with a modified Rankin Scale (mRS) score of 0 to 2 at 90 days (n = 25/57); within 1 year, 8% of patients had recurrent or new strokes (n = 5/59), 6% had symptomatic intracranial hemorrhage [sICH] (4/64), 3% had major extracranial bleeding events (2/64), and 3% had a gastrointestinal bleed (2/64). In our meta-analysis, 11 studies with 298 patients were included. The pooled proportion of sICH and intraprocedural thromboembolic complication events were 0.07 [95% CI 0.04 to 1.13] and 0.08 [95% CI 0.05 to 0.15], respectively.

Conclusion

Our study found that intravenous cangrelor appears to be safe and effective in neuroendovascular procedures, with low rates of bleeding and ischemic events. However, further research is needed to compare different dosing and titration protocols of cangrelor and other intravenous agents.

Using theory of change to co-create a programme theory for a telerehabilitation intervention for pain management in people with haemophilia

BACKGROUND

Improved approaches for chronic pain management are a clinical and research priority for people with haemophilia (PWH). Involving people with lived experience in the design of a complex rehabilitation intervention strengthens the credibility and plausibility of the intervention, particularly in relation to rare disorders. Here we describe using a 'Theory of Change' (ToC) dialogue-based stakeholder process to create a programme theory for a telerehabilitation intervention.

METHODS

An online workshop was convened and stakeholders received a briefing document in advance. Five stakeholders took part (3 PWH and 2 physiotherapists). At the workshop the group first agreed the overall aim of the intervention. Discussions then identified the resources, activities, barriers and enablers needed to achieve this outcome. All discussions were recorded and annotated by the workshop moderator. Behaviour change techniques were mapped for inclusion in the theory.

RESULTS

A programme theory and narrative report were produced. All stakeholders reviewed these for clarity and to ensure a true reflection of the workshop discussions. Agreement was based on how meaningful, well-defined, do-able, plausible, credible, and testable each component was. Stakeholders highlighted the importance of issues unique to PWH. Key components included the need for physiotherapists to be knowledgeable of the condition, a range of exercises that were inclusive of all abilities, and the need for people to feel safe and supported whilst taking part.

CONCLUSIONS

Co-developed theory based approaches to intervention design offer an inclusive and transparent way to develop novel and meaningful interventions for people with complex health conditions. The ToC is wholly transparent in its design and content. Together with the identified behaviour change techniques, the theory informs the protocol for a feasibility study evaluating a telerehabilitation intervention. Importantly, it allows the opportunity to revise, adapt and improve the programme theory for further implementation and evaluation.

Community-based care for people with chronic knee and hip pain: Preliminary clinical outcomes and healthcare utilisation for ESCAPE-pain

BACKGROUND

Joint pain impairs physical and psychosocial wellbeing, quality of life (QoL) and has a significant socioeconomic impact. Enabling Self-management and Coping with Arthritic Pain using Exercise, ESCAPE-pain, is a rehabilitation programme that mitigates the wide impacts of joint pain. Financial, logistical and workforce constraints in health systems severely limit access to the programme. Delivering the programme by trained exercise professionals in community venues could increase access and reduce costs.

METHODS

Four hundred eighty-two exercise professionals were trained to deliver ESCAPE-pain at community sites to people >55 years with chronic knee or hip pain. Pain, physical function, QoL, self-reported activity, mental wellbeing and healthcare utilisation (consultations, investigations, treatments, medication) were measured before, immediately after and 6 months after the programme.

RESULTS

One thousand four hundred ninety-two people (mean age 70 years) were recruited. ESCAPE-pain improved pain, function, QoL, mental wellbeing and objective physical function (p < 0.0001). Before the programme, only 24% of participants were classified as 'fairly active/active' (doing ≥30 min activity/week); after the programme, 78% were classified as 'fairly active/active'; 6 months later, 69% were still 'fairly active/active'. Participants used less healthcare after ESCAPE-pain, resulting in savings of £326.16/participant.

CONCLUSIONS

Older people with chronic joint pain were willing to attend ESCAPE-pain when delivered by exercise professionals in community centres, and it was found to be as effective as when delivered by physiotherapists in hospitals. Delivering ESCAPE-pain in the community could facilitate access to effective care and on-going support to sustain the benefits of healthcare programmes, producing a more efficient use of health and community resources.

Outcomes of Chimeric Antigen Receptor (CAR) T-Cell Therapy in Patients with Large B-Cell Lymphoma (LBCL): A Single-Institution Experience

Chimeric antigen receptor T-cell (CAR T-cell) therapy has revolutionized the treatment of relapsed/refractory (R/R) large B-cell lymphoma (LBCL). We describe the real-world baseline characteristics, efficacy, safety, and post-relapse outcomes of adult patients with R/R LBCL who received CAR T-cell therapy at the University of California San Diego. A total of 66 patients with LBCL were treated with tisagenlecleucel or axicabtagene ciloleucel. The median age was 59.5, and 21% were over 70 years old. Additionally, 20% of the patients had an Eastern Cooperative Oncology Group (ECOG) performance score of ≥2. Cytokine release syndrome incidence was 88%; immune effector cell-associated neurotoxicity syndrome incidence was 56%. All-grade infection occurred in 48% of patients and in 79% of patients > 70 years old. Complete response (CR) was achieved in 53% and partial response in 14%. Median progression-free survival (PFS) was 10.3 months; median overall survival (OS) was 28.4 months. Patients who relapsed post-CAR T-cell therapy had poor outcomes, with a median OS2 of 4.8 months. Upon multivariate analysis, both ECOG (HR 2.65, 95% CI: 1.30-5.41; p = 0.007) and ≥2 sites of extranodal involvement (HR 2.22, 95% CI: 1.15-4.31; p = 0.018) were significant predictors of PFS. Twenty-six patients were R/R to CAR T-cell therapy; six patients were in remission at the time of data cut off, one of whom received allogeneic transplant. Overall, older patients can safely undergo CAR T-cell therapy, despite the increased risk of all-grade infection. In our cohort, ECOG performance score and ≥2 sites of extranodal disease are significant predictors of PFS.

The experiences and beliefs of people with severe haemophilia and healthcare professionals on pain management, and their views of using exercise as an aspect of intervention: a qualitative study

PURPOSE

To explore the experiences, views and beliefs of people with severe haemophilia and healthcare professionals (HCPs) on approaches for pain management, as well as their views on exercise being used as an aspect of management.

METHODS

Taking a qualitative inquiry approach using focus groups and semi-structured interviews, participants included people with severe haemophilia living with chronic pain and haemophilia HCPs. Data were analysed using reflexive thematic analysis.

RESULTS

Fourteen men with haemophilia with a median age of 47 (range 23-73) and six haemophilia HCPs agreed to participate. Of the people with haemophilia, 11 attended two focus groups and three were interviewed over telephone. Healthcare professionals were interviewed face-to-face. Two themes were conceptualised from the data: (i) haemophilia management and pain management is discordant (imbalance between good haemophilia care but poor pain management, historical medico-social influences on pain management, the need for trust); (ii) uncertain about exercise but clear on what matters (conflicting views on exercise, the need for proof of safety, personalised care).

CONCLUSIONS

Options for effective pain management remain limited and what is used is heavily influenced by beliefs and experience. Exercise as a treatment option in pain management is conceptually acceptable for people with haemophilia. Effective pain management requires understanding of individual beliefs and fears, and a personalised approach supported by knowledgeable, trusted clinicians.Implications for rehabilitationMusculoskeletal joint pain and its relationship with bleeding in people with haemophilia continues to be a management challenge.Current pain management strategies are of limited effectiveness with little evidence of an approach that reflects the multi-modal pain experience.Whilst exercise and rehabilitation approaches are conceptually possible for people with severe haemophilia, barriers remain regarding perception of overall safety and effectiveness.People with severe haemophilia may consider exercise as part of a pain management strategy if it is individualised, and they are supported to do it by clinicians who understand them and their haemophilia.

How does a lifetime of painful experiences influence sensations and beliefs about pain in adults with severe haemophilia? A qualitative study

PURPOSE

To explore the life experiences of pain in people with severe haemophilia and understand how such experiences influence beliefs and sensation of pain in adulthood.

METHODS

A qualitative inquiry approach using focus groups and semi-structured individual interviews was used. Participants included people with severe haemophilia living with chronic pain. Data were analysed using reflexive thematic analysis.

RESULTS

Fourteen men with a median age of 47 (range 23-73) agreed to take part. Eleven participated in two focus groups and three were interviewed over telephone. Two themes were conceptualised from the data: (i) haemophilia and pain - an evolving life biography (the personal narrative, historical, social, and medical context, continuous adaptation of activity choices, surveillance of pain and its meaning); (ii) "My normal isn't normal" - identity and self-agency (pain as a feature of life and identify with severe haemophilia, loss of enjoyable activities balanced against staying active, barriers to participation).

CONCLUSIONS

Pain is a constantly evolving, lifetime feature for many adults with haemophilia and it is viewed as part of their identity with their condition. Healthcare professionals working in haemophilia should try to better understand the influence of an individuals lived experience with their haemophilia on beliefs and behaviours of pain.Implications for rehabilitationSevere haemophilia is a rare bleeding disorder that results in musculoskeletal joint disease.Adults with severe haemophilia have experienced multiple episodes of bleeding related musculoskeletal pain since childhood.Pain beliefs and behaviours in adulthood appear to be influenced by a lifetime of painful experiences associated with haemophilia.In order to better support people with haemophilia and chronic pain, healthcare professionals in haemophilia need to better understand how an individuals lived experience of pain helps inform their beliefs about it.

A qualitative evaluation of participants experiences of living with back pain, lumbar fusion surgery, and post-operative rehabilitation

Background

The use of lumbar fusion surgery is increasing in developed economies. High levels of patient dissatisfaction are reported post-operatively. To address this need, we developed a theoretically informed rehabilitation programme for use following lumbar fusion surgery (the REFS programme). We conducted a mixed methods randomised controlled feasibility study (REFS v ‘usual care’). The numerical and feasibility outcomes are reported separately. The current qualitative study was ‘nested’ within the main feasibility study to explore participants’ experiences before and after lumbar fusion surgery including the impact of rehabilitation content. This facilitated a deeper understanding of potential mechanisms of action, for theoretical and programme refinement.

Methods

A purposive sample (n = 10 ‘usual care’, n = 10 REFS) was identified from the main feasibility study cohort. Individual semi-structured interviews were conducted post-operatively (median 8 months, range 5–11). Interview data were transcribed verbatim, coded, and analysed thematically.

Results

Three themes were constructed: the breadth and severity of impact associated with a chronic lumbar disorder was summarised in theme 1, ‘Ever-decreasing circles; living with a chronic lumbar disorder’. Theme 2, ‘What have I done? Reflections on recovery from lumbar fusion surgery’, illustrated participants post-operative helplessness, which was associated with worsening mental health, problematic use of opioids, fear related to the instillation of metalware, and the important mitigating effect of informal social support. Theme 3 ‘Rehabilitation experiences’ identified critical rehabilitation programme content including exercise, a shared rehabilitation experience, the opportunity for vicarious learning, and professional expertise.

Conclusions

To enhance patient benefit future REFS programme iterations should consider reinforcement of the identified valued programme content. Additional content should be considered to mitigate post-operative fear, which frequently aligned with the instillation of metalware into the spine. Participant’s perceptions regarding the necessity of lumbar fusion surgery has potential implications for the surgical consent process.

P107 Improving care for people with chronic low back pain - ESCAPE-pain for back

Background/Aims

Chronic low back pain (cLBP) is extremely prevalent, difficult to manage and impinges and all aspects of an individual’s life and its socioeconomic impact is enormous. ESCAPE-pain is an effective rehabilitation programme for knee and hip pain that is now being rolled out across the UK and beyond. We adapted ESCAPE-pain making it relevant to people with cLBP to improve their management. This study evaluated the efficacy of the programme in improving pain, function and mental well-being for people with cLBP.

Methods

Participants attended 12 sessions (2/week over 6 weeks) in groups of ∼10. Each session lasted 60-90 minutes, comprised of education and supervised, progressive exercise regimen. It was delivered by physiotherapists and therapy assistants. Data collected before and after the programme on MSK-HQ, self-reported physical activity (days active for 30 minutes each week) and function (30 second sit-to-stand). Feasibility was established from the number of Trusts willing to deliver the programme, participant recruitment and attendance. Participant and clinician satisfaction with, acceptability and experiences of the programme was gleaned from qualitative feedback from the “friends and family test” and semi-structured interviews.

Results

Four NHS Trusts took up the offer to deliver the programme, 165 people (106 women), mean age 55yrs were recruited. On average 78% of participants attended 74% of the programme. All Trusts were planning the continue to deliver and expand the programme after the evaluation ended. This uptake by organisations and participants is a proxy measure of the acceptability of the programme to providers and participants. The average number of days each week participant’s undertook for more than 30 mins physical activity increased from 2.3 to 3.6, number of sit-to-stand participants could perform in 30 seconds increased from 8 to 12, and mean MSK-HQ score increased from 25.5 to 35.2 (9.97).

Participant feedback was very positive describing how they “⋯gained lots of information to help me manage my pain...”,“⋯when I started I could only walk for 10 minutes before the pain started. I can now walk a lot further and I do not need to stop...”,“⋯I received the knowledge to understand that it is not just rest that I need for my pains but also activity and exercise...”,“⋯helped me feel more motivated and confident to exercise⋯”,“⋯it has improved the quality of my life and I feel a whole lot better⋯”

Conclusion: ESCAPE-pain for backs was accepted, well liked and improved clinical outcomes. The programme delivered care in line with NICE guidelines. The organisations were planning to expand delivery across other sites within their Trusts. Following wide expressions of interest we are rolling out of ESCAPE-pain for backs in NHS, leisure and community centres across the UK.

P108 Delivering NICE Joint Pain Advice in the workplace

Background/Aims

Knee, hip and back pain is ubiquitous. NICE’s recommendations are that people with persistent knee, hip and/or back pain receive self-management advice about the importance of physical activity and maintaining healthy body weight. However, people worry about moving and activity which they associate with the onset of pain, fear activity may do more harm than good and consequently refrain from activity (fear-avoidance behaviour), which causes muscles, cartilage and bone atrophy and joint stiffness. Delivering NICE advice to many millions of people is problematic because of limited time and expertise needed to deliver effective lifestyle advice. We introduced a Joint Pain Advice (JPA) service to deliver NICE advice in a variety of health and community settings delivered by a variety of professionals (physiotherapists, health trainers and navigators, community pharmacists). We have now extended JPA by training occupational health and workplace champions to deliver the service in workplace settings.

Methods

In workplaces, 2-3 people were trained to deliver the JPA service. This involved an initial (30-minute) assessment when the Advisor assessed participant’s pain, function, activity level, body mass, taught simple self-management strategies (weight control, exercise), used behavioural change techniques (motivational interviewing, goal-setting, action/coping planning) and constructed personalised care plans. Participants were reviewed 3 times up to 6-months later, when outcome measures were repeated, progress highlighted, health messages reinforced, on-going support offered and reassurance and encouragement given. Qualitative interviews assessed people's opinions of the effectiveness and value.

Results

12 employers delivered JPA, 417 people accessed the service. Overall musculoskeletal health and function measured by the MSK-HQ increased by 8 points (CI 6.6 to 9.2), pain decreased 1 point (CI -1.33 to -0.88), number of sit-to-stand performed in 30secs increased by 2.8 (CI 2.0 to 3.6), number of days active for &gt;30mins each week increased by 1.5 (1.1 to 1.8) and self-reported physical function increased 1.5 point (CI 1.1 to 1.8). Employer’s satisfaction with JPA was good (most were considering embedding the service into their organisation) and participant attendance was good (75%), suggesting employers and employees found JPA acceptable and valuable. Problems (inappropriate referrals, failure to attend) were identified and surmounted as possible. People valued advice tailored to their individual needs, appreciated access to care, and the tangible benefits. We are currently evaluating the impact of JPA on absenteeism, presenteeism and healthcare utilisation.

Conclusion

Delivering core NICE advice through a Joint Pain Advice service in workplace settings is needed, practicable, beneficial and valued. JPA has the potential to treat people in their workplaces and communities and “prevent turning people into patients”. We are planning to increase the access of employees to JPA in small medium or large employers.

Characterization of Internal Medicine Chief Resident Administrative, Educational, and Clinical Experiences

IMPORTANCE

The internal medicine (IM) chief residency is a position of leadership and honor common in IM programs, but the goals, responsibilities, and experiences of those who undertake it can be highly variable. Studies assessing the experience and impressions of the chief resident (CR) position from the viewpoint of the IM CRs are lacking.

OBJECTIVE

To describe the structure, responsibilities, and perceptions of the IM CR role across IM residency programs.

DESIGN, SETTING, AND PARTICIPANTS

A cross-sectional, simple descriptive electronic survey for current CRs was administered between April and June 2018 across US IM residency programs accredited by US Accreditation Council for Graduate Medical Education. A 2-step nonrandom sampling approach was used: first, snowball sampling was performed using the authors' professional networks, and second, the survey was sent to the Association of Program Directors in Internal Medicine (APDIM) CR listserv. Data analysis was performed from June 2020 to August 2020.

EXPOSURES

Participation as a CR for an IM residency program in the 2017 to 2018 academic year.

MAIN OUTCOMES AND MEASURES

Descriptive CR personal and program characteristics and CR perceptions of administrative, clinical, and leadership experiences.

RESULTS

Among 169 unique responses, 77 participants (46%) were female and 89 (53%) were White. The response rate was 57% (70 of 122 surveys) in the snowball sample and 12% (99 of 842 surveys) in the APDIM listserv. The 2 sampled groups were combined for analysis. Most respondents (125 CRs [74%]) were from academic or university-based programs. Common across CR responses was responsibility for administrative tasks, clinical work, and educational efforts. Most CRs (111 of 157 respondents [71%]) reported being the primary schedulers for the residency program. Clinical work differed widely across respondents. Only 70 of 156 respondents (45%) reported having an academic title associated with the CR role. CRs reported inconsistent evaluation throughout the year, with high percentages reporting never receiving feedback on teaching (34 respondents [23%]), clinical abilities (67 respondents [45%]), or leadership abilities (60 respondents [40%]). Most CRs (107 respondents [69%]) agreed that they find work as a CR fulfilling and 117 (74%) agreed they would do chief residency again.

CONCLUSIONS AND RELEVANCE

Despite its ubiquity in training programs across the US, the IM CR experience is very different across programs. Recommendations are provided to consider for improvement of the CR experience, including structured feedback opportunities, maximizing educational and clinical experiences, and standardizing policies.

Assessing CAR T-Cell Therapy Response Using Genome-Wide Sequencing of Cell-Free DNA in Patients With B-Cell Lymphomas

Methods that enable monitoring of therapeutic efficacy of autologous chimeric antigen receptor (CAR) T-cell therapy will be clinically useful. The aim of this study is to demonstrate the feasibility of blood-derived cell-free DNA (cfDNA) to predict CAR T-cell therapy response in patients with refractory B-cell lymphomas. Whole blood was collected before and throughout CAR T-cell therapy until day 154. Low-coverage (∼0.4×), genome-wide cfDNA sequencing, similar to that established for noninvasive prenatal testing, was performed. The genomic instability number (GIN) was used to quantify plasma copy number alteration level. Twelve patients were enrolled. Seven (58%) patients achieved a complete response (CR); 2 (25%), a partial response. Median progression-free survival was 99 days; median overall survival was not reached (median follow-up, 247 days). Altogether, 127 blood samples were analyzed (median, 10 samples/patient [range 8-13]). All 5 patients who remained in CR at the time of last measurement had GIN <170 (threshold). Two patients who attained CR, but later relapsed, and all but one patient who had best response other than CR had last GIN measurement of >170. In 5 of 6 patients with relapsed or progressive disease, increasing GIN was observed before the diagnosis by imaging. The abundance of CAR T-cell construct (absolute number of construct copies relative to the number of human genome equivalents) also showed a trend to correlate with outcome (day 10, P = .052). These data describe a proof-of-concept for the use of multiple liquid biopsy technologies to monitor therapeutic response in B-cell lymphoma patients receiving CAR T-cell therapy.

Providing easier access to community-based healthcare for people with joint pain: Experiences of delivering ESCAPE-pain in community venues by exercise professionals

Background

Joint pain adversely impacts the physical, mental, socioeconomic and emotional wellbeing of many millions of people. Enabling Self‐management and Coping with Arthritic Pain using Exercise, ESCAPE‐pain, is a rehabilitation programme that reduces joint pain and its impact. The programme is usually delivered in clinical settings by physiotherapists but delivering it in community venues would improve access greatly.

Aim

To explore the feasibility of delivering ESCAPE‐pain in community venues, and the experiences of organisations and facilitators delivering it.

Methods

Semi‐structured interviews were conducted with managers of 17 community organisations and 10 facilitators.

Results

People were happy to attend ESCAPE‐pain delivered by exercise professionals at community venues, which they found convenient and valuable. It expanded community organisation's offer to older people, utilised their facilities off‐peak and advanced facilitator's personal and professional development. Recruitment onto the programme was easiest where there were good links with local clinical providers. Although collecting outcome data was burdensome it demonstrated the programme's effectiveness to commissioners. Some clinical commissioners contracted community organisations to deliver ESCAPE‐pain reducing their costs and freeing up clinical facilities. Organisations also financed ESCAPE‐pain by charging participants a nominal fee for the programme, post‐programme classes to support participants remain active and/or a membership fee.

Conclusions

ESCAPE‐pain delivered in community venues facilitated access to better care and on‐going support. Partnerships between healthcare commissioners and community providers maximised efficient use of their facilities and resources and fulfilled national policy of encouraging self‐management of long‐term conditions in the community.

Sacrificed: Ontario Healthcare Workers in the Time of COVID-19

Healthcare workers (HCWs) in Ontario, Canada have faced unprecedented risks during the COVID-19 pandemic. They have been infected at an elevated rate compared to the general public. HCWs have argued for better protections with minimal success. A worldwide shortage of N95s and comparable respirators appears to have influenced guidelines for protection, which stand at odds with increasing scientific evidence. In-depth interviews were conducted with ten frontline HCWs about their concerns. They reported that the risk of contracting COVID-19 and infecting family members has created intense anxiety. This, in conjunction with understaffing and an increased workload, has resulted in exhaustion and burnout. HCWs feel abandoned by their governments, which failed to prepare for an inevitable epidemic, despite recommendations. The knowledge that they are at increased risk of infection due to lack of protection has resulted in anger, frustration, fear, and a sense of violation that may have long-lasting implications.Sacrifié: Le personnel de la santé ontarien à l'époque de la COVID-19RésuméEn Ontario, au Canada, le personnel de la santé a eu à faire face à des risques sans précédent durant la pandémie de COVID-19. On y a constaté un taux d'infection plus élevé chez les travailleuses et travailleurs de la santé (TTS) qu'au sein de la population en général. Les TTS ont revendiqué des moyens de protection améliorés, sans grand succès. Une pénurie mondiale de masques respirateurs de type N95 ou similaires semble avoir joué sur les directives en matière de protection, qui ne cadrent pas avec une accumulation de preuves scientifiques. Lors d'entretiens en profondeur, dix TTS de première ligne ont été invités à donner leur avis sur la situation. à les entendre, le risque de contracter la COVID-19 et d'infecter les membres de leur famille leur cause beaucoup d'anxiété. Associée à un manque de personnel et à une charge de travail accrue, cette anxiété se traduit par un épuisement physique et professionnel. Les TTS se sentent abandonnés par leurs gouvernements, qui ont manqué de se préparer à l'inévitabilité d'une épidémie, malgré ce qui leur avait été recommandé. Leur réalisation d'être exposés à un plus grand risque d'infection par manque d'équipement de protection s'est muée en colère, frustration et peur, et en un sentiment de violation de leurs droits dont on peut craindre qu'il subsiste fort longtemps.

Physiotherapy interventions for pain management in haemophilia: A systematic review

PURPOSE

Approximately 35%-50% of people with haemophilia (PWH) report living with chronic musculoskeletal pain. Although exercise based rehabilitation is effective for pain in other arthritises, there are no published guidelines for management of chronic pain in PWH. This review aims to evaluate and appraise the current evidence of effectiveness of physiotherapy interventions on (a) pain intensity, (b) quality of life (QoL) and (c) function in PWH.

METHODS

A systematic review of five databases AMED and CINAHL, EMBASE and MEDLINE and PEDro, as well as trial registries, grey literature and hand searching key journals was completed. Included studies were critically appraised and evaluated for risk of bias. The GRADE approach was used to rate the quality of the evidence.

RESULTS

Nine trials consisting of 235 participants met the inclusion criteria. All studies had an overall risk of bias with low methodological quality. Meta-analysis was not possible due to heterogeneity across trials. Studies comparing a range of physiotherapy interventions against no intervention showed no clear beneficial effect on pain intensity or QoL. Only one study, investigating hydrotherapy or land-based exercise against control, showed positive effect for pain intensity, but rated very low on GRADE assessment. Studies comparing one physiotherapy intervention against another showed no clear benefit on pain intensity, QoL or function. LASER with exercise and hydrotherapy were shown to have some positive effects on pain intensity, but no clear benefit on function.

CONCLUSIONS

At present, there is limited evidence for the use of physiotherapy interventions in addressing the issue of pain in PWH. Better designed trials with higher quality and explicit methodology along with user involvement are needed to assess the efficacy of any proposed intervention.

Breaking Point: Violence Against Long-Term Care Staff

Direct resident care in long-term care facilities is carried out predominantly by personal support workers and registered practical nurses, the majority of whom are women. They experience physical, verbal, and sexual violence from residents on a regular basis. To explore this widespread problem, fifty-six staff in seven communities in Ontario, Canada, were consulted. They identified such immediate causes of violence as resident fear, confusion, and agitation and such underlying causes as task-driven organization of work, understaffing, inappropriate resident placement, and inadequate time for relational care. They saw violence as symptomatic of an institution that undervalues both its staff and residents. They described how violence affects their own health and well-being-causing injuries, unaddressed emotional trauma, job dissatisfaction, and burnout. They outlined barriers to preventing violence, such as insufficient training and resources, systemic underfunding, lack of recognition of the severity and ubiquity of the phenomenon, and limited public awareness.

Abstract TMP108: Evaluation of Cerebral Arteriovenous Malformations using Flow Distribution Network Graphs and Dual-VENC 4D Flow MRI

Introduction: Cerebral arteriovenous malformation (AVM) is the most common cause of hemorrhagic stroke in young adults. AVM affects the total blood flow to the brain as well as the extranidal flow distribution, yet quantitative data relating AVM hemodynamic parameters to hemorrhage risk are lacking. 4D Flow MRI provides time-resolved 3D blood flow velocity with full volumetric coverage of principal arteries and veins. This study aims to investigate the impact of anatomical differences in vessel connectivity on blood flow, and to identify potential quantitative biomarkers for AVM stroke risk stratification.

Methods: 4D flow MRI was obtained for healthy controls (n = 26) and patients with unruptured AVM (n = 5, Fig. 1A). A semiautomated in-house tool was used to compute blood flow and peak velocity at multiple points per vessel from 4D flow data (Fig. 1B). Results and vessel connectivity are schematically summarized as a Flow Distribution Network Graph (FDNG) for group comparison and secondary metrics.

Results: In the healthy cohort, we identified 3 main COW variants: A (complete COW, n = 13), B (no RPCOM, n = 5) and C (both PCOMs missing, n = 4). Group comparison FDNGs (Fig. 1C) show significant differences between groups A and B in RICA flow (p = 0.026) and right A/P flow ratio (p = 0.036). AVMs were characterized by total cerebral blood flow and flow diversion to the nidus. AVM draining veins had significantly higher peak velocity (p = 0.032) relative to feeding arteries than non-draining veins relative to non-feeding arteries and control venous/arterial ratios (p = 0.002, Fig. 1D).

Conclusions: Network analysis of 4D flow MRI data can identify significant differences in flow distribution between normal variant groups and provide standardized metrics of AVM hemodynamics, including peak velocity, which specifically distinguishes AVM nidal flow. These metrics account for individual vascular network variation and may provide a path forward for risk stratification.

A qualitative study exploring therapists' experiences of implementing a complex intervention promoting meaningful activity for residents in care homes

OBJECTIVES:

To explore the experiences of occupational therapists and physiotherapists and to reveal any factors that can facilitate delivering a complex care home intervention promoting meaningful activity.

DESIGN:

Qualitative interview study using data from three focus groups conducted longitudinally post intervention implementation. Data were analysed thematically.

SETTING:

Three residential care homes in South London, UK.

SUBJECTS:

All therapists involved in the implementation of the intervention: three occupational therapists and three physiotherapists.

RESULTS:

Three interconnected themes emerged from the analysis: (1) developing trusting relationships, (2) empowering staff and (3) remaining flexible. Therapists described how successfully implementing a complex care home intervention was dependant on developing trusting relationships with care staff. This enabled the therapists to empower care staff to take ownership of the intervention and help embed it in care home culture, facilitating long-term change. The therapists described how remaining flexible in their approach helped keep care staff engaged for the duration of implementation.

CONCLUSION:

This study has revealed several important factors that can help facilitate therapists delivering complex interventions in care homes.

Exercise interventions and patient beliefs for people with hip, knee or hip and knee osteoarthritis: a mixed methods review

BACKGROUND

Chronic peripheral joint pain due to osteoarthritis (OA) is extremely prevalent and a major cause of physical dysfunction and psychosocial distress. Exercise is recommended to reduce joint pain and improve physical function, but the effect of exercise on psychosocial function (health beliefs, depression, anxiety and quality of life) in this population is unknown.

OBJECTIVES

To improve our understanding of the complex inter-relationship between pain, psychosocial effects, physical function and exercise.

SEARCH METHODS

Review authors searched 23 clinical, public health, psychology and social care databases and 25 other relevant resources including trials registers up to March 2016. We checked reference lists of included studies for relevant studies. We contacted key experts about unpublished studies.

SELECTION CRITERIA

To be included in the quantitative synthesis, studies had to be randomised controlled trials of land- or water-based exercise programmes compared with a control group consisting of no treatment or non-exercise intervention (such as medication, patient education) that measured either pain or function and at least one psychosocial outcome (self-efficacy, depression, anxiety, quality of life). Participants had to be aged 45 years or older, with a clinical diagnosis of OA (as defined by the study) or self-reported chronic hip or knee (or both) pain (defined as more than six months' duration).To be included in the qualitative synthesis, studies had to have reported people's opinions and experiences of exercise-based programmes (e.g. their views, understanding, experiences and beliefs about the utility of exercise in the management of chronic pain/OA).

DATA COLLECTION AND ANALYSIS

We used standard methodology recommended by Cochrane for the quantitative analysis. For the qualitative analysis, we extracted verbatim quotes from study participants and synthesised studies of patients' views using framework synthesis. We then conducted an integrative review, synthesising the quantitative and qualitative data together.

MAIN RESULTS

Twenty-one trials (2372 participants) met the inclusion criteria for quantitative synthesis. There were large variations in the exercise programme's content, mode of delivery, frequency and duration, participant's symptoms, duration of symptoms, outcomes measured, methodological quality and reporting. Comparator groups were varied and included normal care; education; and attention controls such as home visits, sham gel and wait list controls. Risk of bias was high in one and unclear risk in five studies regarding the randomisation process, high for 11 studies regarding allocation concealment, high for all 21 studies regarding blinding, and high for three studies and unclear for five studies regarding attrition. Studies did not provide information on adverse effects.There was moderate quality evidence that exercise reduced pain by an absolute percent reduction of 6% (95% confidence interval (CI) -9% to -4%, (9 studies, 1058 participants), equivalent to reducing (improving) pain by 1.25 points from 6.5 to 5.3 on a 0 to 20 scale and moderate quality evidence that exercise improved physical function by an absolute percent of 5.6% (95% CI -7.6% to 2.0%; standardised mean difference (SMD) -0.27, 95% CI -0.37 to -0.17, equivalent to reducing (improving) WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) function on a 0 to 100 scale from 49.9 to 44.3) (13 studies, 1599 participants)). Self-efficacy was increased by an absolute percent of 1.66% (95% CI 1.08% to 2.20%), although evidence was low quality (SMD 0.46, 95% CI 0.34 to 0.58, equivalent to improving the ExBeliefs score on a 17 to 85 scale from 64.3 to 65.4), with small benefits for depression from moderate quality evidence indicating an absolute percent reduction of 2.4% (95% CI -0.47% to 0.5%) (SMD -0.16, 95% CI -0.29 to -0.02, equivalent to improving depression measured using HADS (Hospital Anxiety and Depression Scale) on a 0 to 21 scale from 3.5 to 3.0) but no clinically or statistically significant effect on anxiety (SMD -0.11, 95% CI -0.26 to 0.05, 2% absolute improvement, 95% CI -5% to 1% equivalent to improving HADS anxiety on a 0 to 21 scale from 5.8 to 5.4; moderate quality evidence). Five studies measured the effect of exercise on health-related quality of life using the 36-item Short Form (SF-36) with statistically significant benefits for social function, increasing it by an absolute percent of 7.9% (95% CI 4.1% to 11.6%), equivalent to increasing SF-36 social function on a 0 to 100 scale from 73.6 to 81.5, although the evidence was low quality. Evidence was downgraded due to heterogeneity of measures, limitations with blinding and lack of detail regarding interventions. For 20/21 studies, there was a high risk of bias with blinding as participants self-reported and were not blinded to their participation in an exercise intervention.Twelve studies (with 6 to 29 participants) met inclusion criteria for qualitative synthesis. Their methodological rigour and quality was generally good. From the patients' perspectives, ways to improve the delivery of exercise interventions included: provide better information and advice about the safety and value of exercise; provide exercise tailored to individual's preferences, abilities and needs; challenge inappropriate health beliefs and provide better support.An integrative review, which compared the findings from quantitative trials with low risk of bias and the implications derived from the high-quality studies in the qualitative synthesis, confirmed the importance of these implications.

AUTHORS' CONCLUSIONS

Chronic hip and knee pain affects all domains of people's lives. People's beliefs about chronic pain shape their attitudes and behaviours about how to manage their pain. People are confused about the cause of their pain, and bewildered by its variability and randomness. Without adequate information and advice from healthcare professionals, people do not know what they should and should not do, and, as a consequence, avoid activity for fear of causing harm. Participation in exercise programmes may slightly improve physical function, depression and pain. It may slightly improve self-efficacy and social function, although there is probably little or no difference in anxiety. Providing reassurance and clear advice about the value of exercise in controlling symptoms, and opportunities to participate in exercise programmes that people regard as enjoyable and relevant, may encourage greater exercise participation, which brings a range of health benefits to a large population of people.

Improving access to better care for people with knee and/or hip pain: service evaluation of allied health professional-led primary care

INTRODUCTION

Chronic knee and hip pain is prevalent, impairing mobility, function and quality of life. Allied health professions (AHPs) are better trained and have more time than general practitioners in primary care to advise and support people to adopt healthier lifestyles (maintain healthy weight, increase physical activity) that reduce joint pain. We evaluated whether AHP-led primary care delivering person-centred, practical lifestyle coaching was a feasible, effective way to manage chronic knee and/or hip pain.

METHODS

At initial assessment the 'Joint Pain Advisor' assessed pain, function, quality of life, physical activity, waist circumference and body mass, taught simple self-management strategies and used behaviour change techniques (motivational interviewing, goal setting, action/coping planning) to alter participants' lifestyles. Participants were invited for 6-week and 6-month reviews, when the Advisor reassessed clinical outcomes, fed back progress and reinforced health messages. Feasibility and effectiveness of the service was evaluated using quantitative and qualitative methods.

RESULTS

Uptake of the service was good: 498 people used the service. Between initial assessment and reviews, participants' pain, function, quality of life, weight, waist circumference and physical activity improved (p < 0.005). Service user satisfaction was high; they reported easier access to advice and support tailored to their needs that translated into clinical benefits and a more efficient pathway reducing unnecessary consultations and investigations. Relatively few people returned for a 6-month review as they considered they had received sufficient advice.

CONCLUSIONS

AHP-led care is a popular, effective, efficient and sustainable way to manage joint pain, without compromising safety or quality of care.

Assaulted and Unheard: Violence Against Healthcare Staff

Healthcare workers regularly face the risk of violent physical, sexual, and verbal assault from their patients. To explore this phenomenon, a collaborative descriptive qualitative study was undertaken by university-affiliated researchers and a union council representing registered practical nurses, personal support workers, and other healthcare staff in Ontario, Canada. A total of fifty-four healthcare workers from diverse communities were consulted about their experiences and ideas. They described violence-related physical, psychological, interpersonal, and financial effects. They put forward such ideas for prevention strategies as increased staffing, enhanced security, personal alarms, building design changes, "zero tolerance" policies, simplified reporting, using the criminal justice system, better training, and flagging. They reported such barriers to eliminating risks as the normalization of violence; underreporting; lack of respect from patients, visitors, higher status professionals, and supervisors; poor communication; and the threat of reprisal for speaking publicly. Inadequate postincident psychological and financial support compounded their distress.

Active residents in care homes: A holistic approach to promoting and encouraging meaningful activity for residents living in care homes: Innovative Practice

The active residents in care homes intervention aim to promote meaningful activity among care home residents. Residents, family members and staff from three residential care homes in South London are participating. It is a whole systems approach which involves formal and ‘on the floor’ training to empower care home staff to facilitate activity. Training is delivered by two occupational therapists, a physiotherapist and a rehabilitation assistant. This paper describes the active residents in care homes intervention, the evaluation methods and discusses some preliminary findings.

High-risk sexual behaviours among gay and bisexual men: comparing event-level casual sex encounters among seroconverters and non-seroconverters

BACKGROUND

With increasing use of non-condom-based HIV risk reduction strategies by gay and bisexual men (GBM), we compared occasions of condomless anal intercourse with casual partners (CLAIC) that resulted in HIV transmission and similar occasions when HIV transmission did not occur.

METHODS

We compared two demographically similar samples of Australian GBM. The HIV Seroconversion Study (SCS) was an online cross-sectional survey of GBM recently diagnosed with HIV. The Pleasure and Sexual Health (PASH) study was an online cross sectional survey of GBM generally. Using logistic regression, we compared accounts of CLAIC reported by men in SCS as being the event which led to them acquiring HIV, with recent CLAIC reported by HIV-negative men in PASH.

RESULTS

In SCS, 85.1% of men reported receptive CLAIC, including 51.8% with ejaculation; 32.1% reported having previously met this partner and 28.6% believed this partner to be HIV-negative. Among HIV-negative men in PASH reporting recent CLAIC, 65.5% reported receptive CLAIC, including 29.9% with ejaculation; 59.3% reported having previously met this partner and 70.1% believed this partner to be HIV-negative.

CONCLUSIONS

While both groups of men engaged in CLAIC, how they engaged in CLAIC differed, and the context in which they did so was different. A generic measure of CLAIC conceals the critical elements of HIV risk, particularly the role of receptive CLAIC, among GBM that distinguish those who seroconverted and those who did not. Detailed information about the context and nature of the practise of CLAIC is required for a more complete understanding of HIV risk among GBM.

Forecasting Trends in Disability in a Super-Aging Society: Adapting the Future Elderly Model to Japan

Japan has experienced pronounced population aging, and now has the highest proportion of elderly adults in the world. Yet few projections of Japan's future demography go beyond estimating population by age and sex to forecast the complex evolution of the health and functioning of the future elderly. This study estimates a new state-transition microsimulation model - the Japanese Future Elderly Model (FEM) - for Japan. We use the model to forecast disability and health for Japan's future elderly. Our simulation suggests that by 2040, over 27 percent of Japan's elderly will exhibit 3 or more limitations in IADLs and social functioning; almost one in 4 will experience difficulties with 3 or more ADLs; and approximately one in 5 will suffer limitations in cognitive or intellectual functioning. Since the majority of the increase in disability arises from the aging of the Japanese population, prevention efforts that reduce age-specific morbidity can help reduce the burden of disability but may have only a limited impact on reducing the overall prevalence of disability among Japanese elderly. While both age and morbidity contribute to a predicted increase in disability burden among elderly Japanese in the future, our simulation results suggest that the impact of population aging exceeds the effect of age-specific morbidity on increasing disability in Japan's future.

Developing a Web-Based Version of An Exercise-Based Rehabilitation Program for People With Chronic Knee and Hip Pain: A Mixed Methods Study

Background

Osteoarthritis is highly prevalent and has enormous personal and socioeconomic impact. Enabling Self-management and Coping with Arthritic Pain through Exercise (ESCAPE-pain) is an integrated rehabilitation program that helps people understand how exercise can improve physical and psychosocial well-being. Unfortunately, its availability is limited. A Web-based version of the program could increase access for more people. Many Web-based resources are developed without end-user input and result in over-complex, unwanted, ineffective products with limited uptake.

Objective

The objective of this study was to codesign a Web-based version of ESCAPE-pain that people with chronic joint pain find engaging, informative, and useful.

Methods

To establish older persons' Internet use we conducted a postal survey of 200 people. To establish their opinions, likes or dislikes, and requirements for a Web-based version of the ESCAPE-pain program, we conducted two focus groups with 11 people who had participated in a program based on ESCAPE-pain and two with 13 people who had not. Information from the postal survey and focus groups was used to develop an online prototype website. People's opinions of the prototype website were gauged from thematic analysis of eight semistructured “think aloud” interviews.

Results

The survey response rate was 42% (83/200), of whom 67% (56/83) were female and mean age was 67 years. Eighty-three percent of the people had used the Internet, 69% described themselves as either very confident or confident Internet users, and 77% had looked online for health information. With regard to participating online, 34% had read a commentary or watched a video of someone else’s experience of a health problem and 23% had tracked a health issue. Key qualitative themes emerged that included engagement, acceptability and usability, and structure and content of the program.

Conclusions

Older people use the Internet as a source of health information but have concerns about safe use and quality of information. Users require a credible website that provides personalized information, support, monitoring, and feedback.

Osteoarthritis and mortality: A prospective cohort study and systematic review with meta-analysis

OBJECTIVES

Osteoarthritis (OA) is a leading cause of disability, but the relationship with premature mortality remains uncertain. We aimed to investigate the relationship between OA and mortality from any cause and from cardiovascular disease (CVD).

METHODS

Electronic literature databases searches were conducted to identify prospective studies comparing mortality in a sample of people with and without OA. Risk of all-cause and CVD mortality were summarized using adjusted hazard ratios (HRs) for joint specific (hand, hip, and knee) and joint non-specific OA. New data from the Progetto Veneto Anziani (PRO.V.A.) study were also included.

RESULTS

From the PRO.V.A. study (N = 2927), there was no significant increase in mortality risk for participants with any joint OA (N = 1858) compared to non-OA (all-cause, HR = 0.95, 95% CI: 0.77-1.15 and CVD, HR = 1.12, 95% CI: 0.82-1.54). On meta-analysis, seven studies (OA = 10,018/non-OA = 18,541), with a median 12-year follow-up, reported no increased risk of any-cause mortality in those with OA (HR = 1.10, 95% CI: 0.97-1.25). After removing data on hand OA, a significant association between OA and mortality was observed (HR = 1.18, 95% CI: 1.08-1.28). There was a significant higher risk of overall mortality for (1) studies conducted in Europe, (2) patients with multi-joint OA; and (3) a radiological diagnosis of OA. OA was associated with significantly higher CVD mortality (HR = 1.21, 95% CI: 1.10-1.34).

CONCLUSIONS

People with OA are at increased risk of death due to CVD. The relationship with overall mortality is less clear and may be moderated by the presence of hand OA.
