ItemAddressing surgical inequity for Aboriginal and Torres Strait Islander people in Australia's universal health care system: a call to action(WILEY, 2021-03)Aboriginal and Torres Strait Islander people continue to experience health inequity within the Australian health care system. Little research has examined how disparities in surgical care access and outcomes contribute to Aboriginal health. In this narrative review and call to action, we discuss five care points along the journey to high-quality surgical care: health care seeking, primary health care services, specialist services, surgery and surgical outcomes. We highlight barriers and disparities that exist along this journey, drawing examples from the field of joint replacement surgery. Finally, we present opportunities for change at the health system, health service and clinician level, calling upon researchers, clinicians and policy makers to confront the surgical disparities experienced by Aboriginal and Torres Strait Islander people.

ItemMisconceptions and the Acceptance of Evidence-based Nonsurgical Interventions for Knee Osteoarthritis. A Qualitative Study(GEORG THIEME VERLAG KG, 2021-11)BACKGROUND: In contrast to best practice guidelines for knee osteoarthritis (OA), findings from several different healthcare settings have identified that nonsurgical treatments are underused and TKA is overused. Empirical evidence and qualitative observations suggest that patients' willingness to accept nonsurgical interventions for knee OA is low. A qualitative investigation of why patients may feel that such interventions are of little value may be an important step toward increasing their use in the treatment of knee OA QUESTIONS/PURPOSES: This qualitative study was embedded in a larger study investigating patient-related factors (beliefs/attitudes toward knee OA and its treatment) and health-system related factors (access, referral pathways) known to influence patients' decisions to seek medical care. In this paper we focus on the patient-related factors with the aim of exploring why patients may feel that nonsurgical interventions are of little value in the treatment of knee OA. METHODS: A cross-sectional qualitative study was conducted in a single tertiary hospital in Australia. Patients with endstage knee OA on the waiting list for TKA were approached during their preadmission appointment and invited to participate in one-to-one interviews. As prescribed by the qualitative approach, data collection and data analysis were performed in parallel and recruitment continued until the authors agreed that the themes identified would not change through interviews with subsequent participants, at which point, recruitment stopped. Thirty-seven patients were approached and 27 participated. Participants were 48% female; mean age was 67 years. Participants' beliefs about knee OA and its treatment were identified in the interview transcripts. Beliefs were grouped into five belief dimensions: identity beliefs (what knee OA is), causal beliefs (what causes knee OA), consequence beliefs (what the consequences of knee OA are), timeline beliefs (how long knee OA lasts) and treatment beliefs (how knee OA can be controlled). RESULTS: All participants believed that their knee OA was "bone on bone" (identity beliefs) and most (> 14 participants) believed it was caused by "wear and tear" (causal beliefs). Most (> 14 participants) believed that loading the knee could further damage their "vulnerable" joint (consequence beliefs) and all believed that their pain would deteriorate over time (timeline beliefs). Many (>20 participants) believed that physiotherapy and exercise interventions would increase pain and could not replace lost knee cartilage. They preferred experimental and surgical treatments which they believed would replace lost cartilage and cure their knee pain (treatment beliefs). CONCLUSIONS: Common misconceptions about knee OA appear to influence patients' acceptance of nonsurgical, evidence-based treatments such as exercise and weight loss. Once the participants in this study had been "diagnosed" with "bone-on-bone" changes, many disregarded exercise-based interventions which they believed would damage their joint, in favor of alternative and experimental treatments, which they believed would regenerate lost knee cartilage. Future research involving larger, more representative samples are needed to understand how widespread these beliefs are and if/how they influence treatment decisions. In the meantime, clinicians seeking to encourage acceptance of nonsurgical interventions may consider exploring and targeting misconceptions that patients hold about the identity, causes, consequences, timeline, and treatment of knee OA. LEVEL OF EVIDENCE: Level II, prognostic study.

ItemWhat do people post on social media relative to low back pain? A content analysis of Australian data(ELSEVIER, 2021-08)OBJECTIVE: Low back pain is the leading contributor to the global disability burden. The Global Spine Care Initiative (GSCI) recommend patient-centred care to stem the cost of low back pain. One way to enhance patient-centred care is by better understanding what is relevant for people with low back pain. Exploring social media posts about low back pain could offer this insight and provide valuable information for health care professionals to facilitate active participation in patient-centred care. METHODS: We used an inductive content analysis method. In the form of social media posts, data on Twitter and Instagram were collected from June to August 2018. The posts were geo-targeted to Australia. We recorded the number of status broadcasts that contained a low back pain keyword and responses. We developed a codebook to describe the data and applied it to identify low back pain themes. RESULTS: We analysed 768 posts containing 457 status broadcasts and 311 responses. Almost half (49%) of status broadcasts about low back pain seemed to seek validation. Expressing sympathy (31%) was the most common response to a status broadcast about low back pain. There were no public responses to 76% of status broadcasts about low back pain. Our analysis yielded two core themes, "hear my pain" and "I feel for you". CONCLUSIONS: Posts about low back pain on social media often seem to suggest that the person posting is seeking validation. Responses typically express sympathy or a shared experience; yet, there is no response to most social media posts about low back pain.

ItemHow Do People Communicate About Knee Osteoarthritis? A Discourse Analysis(OXFORD UNIV PRESS, 2021-05)OBJECTIVE: To explore the ways in which people talk about knee osteoarthritis and how this may influence engagement in physical activity and activity-based interventions as recommended by clinical practice guidelines. DESIGN: A qualitative synthesis using discourse analysis methods. METHODS: Systematic review methods were used to identify qualitative studies exploring the perceptions of people with knee osteoarthritis, their carers, and/or clinicians. Methodological quality was evaluated through the use of the Critical Appraisal Skills Programme. Raw quotes extracted from each study were analyzed with inductive discourse analysis. RESULTS: A search of five electronic databases from inception until August 2019 yielded 778 articles. Sixty-two articles from 56 studies were included, reporting data (1,673 direct quotes) from people with knee osteoarthritis, carers, and clinicians in 16 countries. Two overarching discourses were identified-impairment and participation. The overarching impairment discourse prevailed in all participant groups and study settings. In this discourse, knee osteoarthritis was likened to a machine that inevitably wore down over time and required a doctor to repair. The overarching participatory discourse almost always coexisted alongside an impairment discourse. According to this discourse, a "busy body" was perceived as "healthy," and people could remain active despite knee osteoarthritis. CONCLUSION: The prevailing impairment discourse may potentially discourage people from using knees that have passed their "use-by date" and increase reliance on doctors to repair joint damage. Consistent with recommendations in clinical practice guidelines, a participatory discourse may provide an alternative way of communicating that may encourage people with knee osteoarthritis to continue to engage in physical activity by focusing on what they can do, rather than what they cannot do.

ItemPlacebo Surgery Controlled Trials Do They Achieve What They Set Out To Do? A Systematic Review(LIPPINCOTT WILLIAMS & WILKINS, 2021-06)OBJECTIVE: To explore whether placebo surgery controlled trials achieve what they set out to do by investigating discrepancy between projected and actual design aspects of trials identified through systematic review methods. SUMMARY BACKGROUND: Interest in placebo surgery controlled trials is growing in response to concerns regarding unnecessary surgery and the societal cost of low-value healthcare. As questions about the justifiability of using placebo controls in surgery have been addressed, attention is now being paid to more practical concerns. METHODS: Six databases were searched from inception - May 2020 (MEDLINE, Embase, Emcare, APA PsycInfo, CINAHL, Cochrane Library). Placebo surgery controlled trials with a published protocol were included. Three authors extracted "projected" design aspects from protocols and "actual" design aspects from main findings papers. Absolute and relative difference between projected and actual design aspects were presented for each trial. Trials were grouped according to whether they met their target sample size ("completed") and were concluded in a timely fashion. Pairs of authors assessed risk of bias. RESULTS: Of 24 trials with data available to analyse; 3 were completed and concluded within target timeframe; 10 were completed and concluded outside the target timeline; 4 were completed without clear target timeframes; 2 were incomplete and concluded within the target framework; 5 were incomplete and concluded outside the target timeline. Trials which reached the recruitment target underestimated trial duration by 88% and number of recruitment sites by 87%. CONCLUSIONS: Trialists need to factor additional time and sites into future placebo surgery controlled trials. A robust reporting framework of projected and actual trial design is imperative for trialists to learn from their predecessors. REVIEW REGISTRATION: PROSPERO (CRD42019133296).

ItemDemystifying Qualitative Research for Musculoskeletal Practitioners Part 1: What Is Qualitative Research and How Can It Help Practitioners Deliver Best-Practice Musculoskeletal Care?(J O S P T, 2021-11)A progressive understanding of pain, disability, and health requires consideration of factors that may not easily be captured quantitatively. Qualitative research is a valuable tool to explore these "uncountable" phenomena and inform high-quality patient-centered care. Despite the utility of qualitative research in a musculoskeletal context, many practitioners are not familiar with qualitative terms and therefore may not reap the benefits of qualitative approaches. This editorial discusses what qualitative research is and how it can inform musculoskeletal clinical practice. J Orthop Sports Phys Ther 2021;51(11):531-532. doi:10.2519/jospt.2021.0110.

ItemFactors Underlying Patient and Surgeon Willingness to Participate in a Placebo Surgery Controlled trial: A Qualitative Investigation.(Ovid Technologies (Wolters Kluwer Health), 2021-12)OBJECTIVE: To investigate the factors underlying willingness to participate in a hypothetical trial among patients and surgeons, to inform the design of future placebo surgery controlled trials. BACKGROUND: Placebo surgery controlled trials are the gold standard for testing the efficacy of surgical procedures. However, these trials commonly fail to meet the target sample size and terminate underpowered. METHODS: From October 2019 to July 2020, eligible patients were identified from the orthopedic waiting list at a single tertiary hospital and surgeons were identified from orthopedic clinics at three tertiary hospitals in Australia. Qualitative interviews explored factors underlying willingness to participate in a hypothetical trial, including understanding of trial concepts; attitudes; and trial design preferences. Data collection and analysis were conducted in parallel. Recruitment ceased when no new concepts emerged. Interview data were analyzed using reflexive thematic analysis. RESULTS: The majority of surgeons and only a few patients indicated a willingness to participate in a placebo surgery controlled trial. Factors underlying willingness were captured in four themes: (1) Understanding and attitudes toward placebo; (2) Attitudes towards randomization/perception of equipoise; (3) Perception of risk; and (4) Ethical concerns. CONCLUSIONS: To optimize recruitment in the future, trialists may consider embedding strategies into the recruitment process that validate patients' symptoms, encourage an altruistic mindset, address surgeon biases, and involve surgeons in explaining trial concepts to patients. Trialists may also consider designing three arm trials that meet surgeons' preferences for a "low" and "high" fidelity placebo.

ItemDemystifying Qualitative Research for Musculoskeletal Practitioners Part 2: Understanding the Foundations of Qualitative Research(J O S P T, 2021-12)In this second editorial about qualitative research for musculoskeletal practitioners, we turn our attention to the foundational assumptions that underpin all qualitative research. Specifically, we discuss research paradigms, which consist of ontological and epistemological assumptions, as well as the "lens" of the researcher. Understanding these foundational assumptions will help readers interpret the findings of qualitative studies relevant to a musculoskeletal context. J Orthop Sports Phys Ther 2021;51(12):559-561. doi:10.2519/jospt.2021.0113.
