Systematic Review of Shoulder Imaging Abnormalities in Asymptomatic Adult Shoulders (SCRUTINY): Abnormalities of the glenohumeral joint.

OBJECTIVE: The primary objective was to determine the population prevalence of glenohumeral joint imaging abnormalities in asymptomatic adults. METHOD: We systematically reviewed studies reporting the prevalence of X-ray, ultrasound (US), computed tomography, and magnetic resonance imaging (MRI) abnormalities in adults without shoulder symptoms (PROSPERO registration number CRD42018090041). This report presents the glenohumeral joint imaging findings. We searched Ovid MEDLINE, Embase, CINAHL and Web of Science from inception to June 2023 and assessed risk of bias using a tool designed for prevalence studies. The primary analysis was planned for the general population. The certainty of evidence was assessed using a modified Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) for prognostic studies. RESULTS: Thirty-five studies (4 X-ray, 10 US, 20 MRI, 1 X-ray and MRI) reported useable prevalence data. Two studies were population-based (846 shoulders), 15 studies included miscellaneous study populations (1715 shoulders) and 18 included athletes (727 shoulders). All were judged to be at high risk of bias. Clinical diversity precluded pooling. Population prevalence of glenohumeral osteoarthritis ranged from 15% to 75% (2 studies, 846 shoulders, 1 X-ray, 1 X-ray and MRI; low certainty evidence). Prevalence of labral abnormalities, humeral head cysts and long head of biceps tendon abnormalities were 20%, 5%, 30% respectively (1 study, 20 shoulders, X-ray and MRI; very low certainty evidence). CONCLUSION: The population-based prevalence of glenohumeral joint imaging abnormalities in asymptomatic individuals remains uncertain, but may range between 30% and 75%. Better estimates are needed to inform best evidence-based management of people with shoulder pain.

Association of state-level prescription drug monitoring program implementation with opioid prescribing transitions in primary care in Australia.

AIMS: This study aimed to evaluate whether voluntary and mandatory prescription drug monitoring program (PDMP) use in Victoria, Australia, had an impact on prescribing behaviour, focusing on individual patients' prescribed opioid doses and transition to prescribing of nonmonitored medications. METHODS: This was a retrospective cross-sectional study using routinely collected primary healthcare data. A 90-day moving average prescribed opioid dose in oral morphine equivalents was used to estimate opioid dosage. A Markov transition matrix was used to describe how patients prescribed medications transitioned between opioid dose groups and other nonopioid treatment options during 3 transition periods: transition between 2 control periods prior to PDMP implementation (T1 to T2); during the voluntary PDMP implementation (T2 to T3); and during mandatory PDMP implementation (T3 to T4). RESULTS: Among patients prescribed opioids in our study, we noted an increased probability of transitioning to not being prescribed opioids during the mandatory PDMP period (T3 to T4). This increase was attributed mainly to the ceasing of low-dose opioid prescribing. Membership in an opioid dose group remained relatively stable for most patients who were prescribed high opioid doses. For those who were only prescribed nonmonitored medications initially, the probability of being prescribed opioids increased during the mandatory PDMP when compared to other transition periods. CONCLUSION: The introduction of PDMP mandates appeared to have an impact on the prescribing for patients who were prescribed low-dose opioids, while its impact on individuals prescribed higher opioid doses was comparatively limited.

Patients' experience of shoulder disorders: a systematic review of qualitative studies for the OMERACT Shoulder Core Domain Set.

OBJECTIVES: To describe the experiences (including symptoms and perceived impacts on daily living) of people with a shoulder disorder. METHODS: Systematic review of qualitative studies. We searched for eligible qualitative studies indexed in Ovid MEDLINE, Ovid Embase, CINAHL (EBSCO), SportDiscus (EBSCO) and Ovid PsycINFO up until November 2017. Two authors independently screened studies for inclusion, appraised their methodological quality using the Critical Appraisal Skills Programme checklist, used thematic synthesis methods to generate themes describing the experiences reported by participants and assessed the confidence in the findings using the Grading of Recommendations Assessment, Development and Evaluation Confidence in Evidence from Reviews of Qualitative research (GRADE-CERQual) approach. RESULTS: The inclusion criteria were met by eight studies, which included 133 participants (49 females and 84 males) with either rotator cuff disease, adhesive capsulitis, proximal humeral fracture, shoulder instability or unspecified shoulder pain. We generated seven themes to describe what people in the included studies reported experiencing: pain; physical function/activity limitations; participation restriction; sleep disruption; cognitive dysfunction; emotional distress; and other pathophysiological manifestations (other than pain). There were interactions between the themes, with particular experiences impacting on others (e.g. pain leading to reduced activities and sleep disruption). Following grading of the evidence, we considered it likely that most of the review findings were a reasonable representation of the experiences of people with shoulder disorders. CONCLUSION: Patients with shoulder disorders contend with considerable disruption to their life. The experiences described should be considered by researchers seeking to select the most appropriate outcomes to measure in clinical trials and other research studies in people with shoulder disorders.

Programme frequency, type, time and duration do not explain the effects of balance exercise in older adults: a systematic review with a meta-regression analysis.

OBJECTIVE: The objective of this systematic review was to examine the effects of different balance exercise interventions compared with non-balance exercise controls on balance task performance in older adults. DESIGN: Systematic review. DATA SOURCES: Medline, Cumulative Index to Nursing and Allied Health Literature, EMBASE, Scopus and Cochrane Database of Systematic Reviews were searched until July 2017. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Systematic reviews and meta-analyses of randomised trials of balance exercise interventions for older adults were identified for extraction of eligible randomised trials. Eligibility criteria for inclusion of randomised trials in meta-analyses were comparison of a balance exercise intervention with a control group that did not perform balance exercises, report of at least one end-intervention balance outcome measurement that was consistent with the five subgroups of balance exercise identified, and full-text article available in English. RESULTS: Ninety-five trials were included in meta-analyses and 80 in meta-regressions. For four balance exercise types (control centre of mass, multidimensional, mobility and reaching), significant effects for balance exercise interventions were found in meta-analyses (standardised mean difference (SMD) 0.31-0.50), however with considerable heterogeneity in observed effects (I2: 50.4%-80.6%). Risk of bias assessments (Physiotherapy Evidence Database score and funnel plots) did not explain heterogeneity. One significant relationship identified in the meta-regressions of SMD and balance exercise frequency, time and duration explained 2.1% of variance for the control centre of mass subgroup. CONCLUSION: Limitations to this study included the variability in design of balance interventions, incomplete reporting of data and statistical heterogeneity. The design of balance exercise programmes provides inadequate explanation of the observed benefits of these interventions.

Effectiveness of a weekend physiotherapy service on short-term outcomes following hip and knee joint replacement surgery: a quasi-experimental study.

OBJECTIVE:: To investigate the effect of an acute weekend physiotherapy service compared to no physiotherapy service on short-term outcomes following lower limb joint replacement. DESIGN:: Pre-post intervention (quasi-experimental) study nested within two stepped-wedge cluster randomized controlled trials. SETTING:: Public tertiary hospital in Melbourne, Australia. SUBJECTS:: Consecutive patients undergoing hip and knee replacement. INTERVENTIONS:: This study analysed a subgroup of one cluster of the parent trials where acute weekend physiotherapy services were sequentially discontinued in random order from one cluster at a time. Intervention (at the ward level) included six months of existing acute weekend physiotherapy services (Phase 1; n = 130) followed by six months when these services were discontinued (Phase 2; n = 146). MAIN MEASURES:: Acute hospital length of stay and other short-term patient and hospital measures. RESULTS:: Availability of weekend physiotherapy was associated with increased odds of discharge directly home (odds ratio (95% confidence interval): 3.151 (1.039-9.555), P = 0.043) and improved mobility (coefficient: 4.301 (1.500-7.101), P = 0.003). However, hospitalization was perceived as less helpful (coefficient: -1.743 (-2.417 to -1.069), P = 0.013) and acute length of stay was longer, only in multivariable analyses (coefficient: 1.003 (0.105-1.890), P = 0.020) than when weekend physiotherapy services were unavailable. Similar results were observed when examining data according to receipt of weekend physiotherapy services rather than the intervention phase to which each patient was allocated. CONCLUSION:: The weekend physiotherapy service appears to have had beneficial impacts on discharge destination and patient mobility that may outweigh the unfavourable impacts on acute length of stay and patient-perceived helpfulness of hospitalization.

Impact of disinvestment from weekend allied health services across acute medical and surgical wards: 2 stepped-wedge cluster randomised controlled trials.

BACKGROUND: Disinvestment (removal, reduction, or reallocation) of routinely provided health services can be difficult when there is little published evidence examining whether the services are effective or not. Evidence is required to understand if removing these services produces outcomes that are inferior to keeping such services in place. However, organisational imperatives, such as budget cuts, may force healthcare providers to disinvest from these services before the required evidence becomes available. There are presently no experimental studies examining the effectiveness of allied health services (e.g., physical therapy, occupational therapy, and social work) provided on weekends across acute medical and surgical hospital wards, despite these services being routinely provided internationally. The aim of this study was to understand the impact of removing weekend allied health services from acute medical and surgical wards using a disinvestment-specific non-inferiority research design. METHODS AND FINDINGS: We conducted 2 stepped-wedge cluster randomised controlled trials between 1 February 2014 and 30 April 2015 among patients on 12 acute medical or surgical hospital wards spread across 2 hospitals. The hospitals involved were 2 metropolitan teaching hospitals in Melbourne, Australia. Data from n = 14,834 patients were collected for inclusion in Trial 1, and n = 12,674 in Trial 2. Trial 1 was a disinvestment-specific non-inferiority stepped-wedge trial where the 'current' weekend allied health service was incrementally removed from participating wards each calendar month, in a random order, while Trial 2 used a conventional non-inferiority stepped-wedge design, where a 'newly developed' service was incrementally reinstated on the same wards as in Trial 1. Primary outcome measures were patient length of stay (proportion staying longer than expected and mean length of stay), the proportion of patients experiencing any adverse event, and the proportion with an unplanned readmission within 28 days of discharge. The 'no weekend allied health service' condition was considered to be not inferior if the 95% CIs of the differences between this condition and the condition with weekend allied health service delivery were below a 2% increase in the proportion of patients who stayed in hospital longer than expected, a 2% increase in the proportion who had an unplanned readmission within 28 days, a 2% increase in the proportion who had any adverse event, and a 1-day increase in the mean length of stay. The current weekend allied health service included physical therapy, occupational therapy, speech therapy, dietetics, social work, and allied health assistant services in line with usual care at the participating sites. The newly developed weekend allied health service allowed managers at each site to reprioritise tasks being performed and the balance of hours provided by each professional group and on which days they were provided. Analyses conducted on an intention-to-treat basis demonstrated that there was no estimated effect size difference between groups in the proportion of patients staying longer than expected (weekend versus no weekend; estimated effect size difference [95% CI], p-value) in Trial 1 (0.40 versus 0.38; estimated effect size difference 0.01 [-0.01 to 0.04], p = 0.31, CI was both above and below non-inferiority margin), but the proportion staying longer than expected was greater with the newly developed service compared to its no weekend service control condition (0.39 versus 0.40; estimated effect size difference 0.02 [0.01 to 0.04], p = 0.04, CI was completely below non-inferiority margin) in Trial 2. Trial 1 and 2 findings were discordant for the mean length of stay outcome (Trial 1: 5.5 versus 6.3 days; estimated effect size difference 1.3 days [0.9 to 1.8], p < 0.001, CI was both above and below non-inferiority margin; Trial 2: 5.9 versus 5.0 days; estimated effect size difference -1.6 days [-2.0 to -1.1], p < 0.001, CI was completely below non-inferiority margin). There was no difference between conditions for the proportion who had an unplanned readmission within 28 days in either trial (Trial 1: 0.01 [-0.01 to 0.03], p = 0.18, CI was both above and below non-inferiority margin; Trial 2: -0.01 [-0.02 to 0.01], p = 0.62, CI completely below non-inferiority margin). There was no difference between conditions in the proportion of patients who experienced any adverse event in Trial 1 (0.01 [-0.01 to 0.03], p = 0.33, CI was both above and below non-inferiority margin), but a lower proportion of patients had an adverse event in Trial 2 when exposed to the no weekend allied health condition (-0.03 [-0.05 to -0.004], p = 0.02, CI completely below non-inferiority margin). Limitations of this research were that 1 of the trial wards was closed by the healthcare provider after Trial 1 and could not be included in Trial 2, and that both withdrawing the current weekend allied health service model and installing a new one may have led to an accommodation period for staff to adapt to the new service settings. Stepped-wedge trials are potentially susceptible to bias from naturally occurring change over time at the service level; however, this was adjusted for in our analyses. CONCLUSIONS: In Trial 1, criteria to say that the no weekend allied health condition was non-inferior to current weekend allied health condition were not met, while neither the no weekend nor current weekend allied health condition demonstrated superiority. In Trial 2, the no weekend allied health condition was non-inferior to the newly developed weekend allied health condition across all primary outcomes, and superior for the outcomes proportion of patients staying longer than expected, proportion experiencing any adverse event, and mean length of stay.

What makes weekend allied health services effective and cost-effective (or not) in acute medical and surgical wards? Perceptions of medical, nursing, and allied health workers.

BACKGROUND: There is strong public support for acute hospital services to move to genuine 7-day models, including access to multidisciplinary team assessment. This study aimed to identify factors that might enable an effective and cost-effective weekend allied health services on acute hospital wards. METHODS: This qualitative study included 22 focus groups within acute wards with a weekend allied health service and 11 telephone interviews with weekend service providers. Data were collected from 210 hospital team members, including 17 medical, 97 nursing, and 96 allied health professionals from two Australian tertiary public hospitals. All were recorded and imported into nVivo 10 for analysis. Thematic analysis methods were used to develop a coding framework from the data and to identify emerging themes. RESULTS: Key themes identified were separated into issues perceived as being enablers or barriers to the effective or cost-effective delivery of weekend allied health services. Perceived enablers of effectiveness and cost-effectiveness included prioritizing interventions that prevent decline, the right person delivering the right service, improved access to the patient's family, and ability to impact patient flow. Perceived barriers were employment of inexperienced weekend staff, insufficient investment to see tangible benefit, inefficiencies related to double-handling, unnecessary interventions and/or inappropriate referrals, and difficulty recruiting and retaining skilled staff. CONCLUSIONS: Suggestions for ensuring effective and cost effective weekend allied health care models include minimization of task duplication and targeting interventions so that the right patients receive the right interventions at the right time. Further research into the effectiveness and cost effectiveness of these services should factor in hidden costs, including those associated with managing the service.

Patient and Therapist Agreement on Performance-Rated Ability Using the de Morton Mobility Index.

OBJECTIVE: To determine the level of agreement between patient self-report and therapist-assessed performance of mobility using the de Morton Mobility Index (DEMMI). DESIGN: Interrater agreement study. SETTING: Outpatient hospital clinic. PARTICIPANTS: Consecutive sample of patients (N=128) undergoing preoperative assessment for elective lower limb (LL) arthroplasty. INTERVENTIONS: Participants completed a therapist-directed assessment of the DEMMI followed by self-report of performance. A random subsample (n=62, 48%) also completed a self-report of anticipated performance before the therapist-directed assessment. Both raters (participant and therapist) were blinded to the scores obtained from the other rater. MAIN OUTCOME MEASURES: Interrater agreement between patient self-report and therapist-directed assessment of the total DEMMI scores was assessed using the intraclass correlation coefficient model 2,1 (ICC2,1) with a 95% confidence interval. The Bland-Altman plots were also used to illustrate the agreement between the 2 raters. RESULTS: The intraclass correlation coefficient (ICC) between patient self-report after performance and therapist-directed assessment of the total DEMMI score was .967 (95% confidence interval, .952-.977). The ICC between patient self-report of anticipated performance and therapist-directed assessment of the total DEMMI score was .830 (95% confidence interval, .730-.894). The Bland-Altman plots depicted higher levels of agreement among participants with impaired levels of mobility (≤74 out of 100) than did those with near-maximum DEMMI scores. CONCLUSIONS: Patient self-report of anticipated performance is an acceptable proxy for DEMMI scores derived from the therapist rating of performance. Caution should be exercised when interpreting self-report scores of patients with near-maximum levels of mobility. Further research is required to establish whether these results can be generalized across a range of patient populations and to clinicians with differing backgrounds and expertise.

Are clinically unimportant findings qualified as benign in lumbar spine imaging reports? A content analysis of plain X-ray, CT and MRI reports.

BACKGROUND: Lumbar spine diagnostic imaging reports may cause patient and clinician concern when clinically unimportant findings are not explicitly described as benign. Our primary aim was to determine the frequency that common, benign findings are reported in lumbar spine plain X-ray, computed tomography (CT) and magnetic resonance imaging (MRI) reports as either normal for age or likely clinically unimportant. METHODS: We obtained 600 random de-identified adult lumbar spine imaging reports (200 X-ray, 200 CT and 200 MRI) from a large radiology provider. Only reports requested for low back pain were included. From the report text, one author extracted each finding (e.g., 'broad-based posterior disc bulge') and whether it was present or absent (e.g., no disc bulge) until data saturation was reached, pre-defined as a minimum of 50 reports and no new/similar findings in the last ten reports within each imaging modality. Two authors independently judged whether each finding was likely clinically unimportant or important. For each likely clinicially unimportant finding they also determined if it had been explicitly reported to be benign (expressed as normal, normal for age, benign, clinically unimportant or non-significant). RESULTS: Data saturation was reached after coding 262 reports (80 X-ray, 82 CT, 100 MRI). Across all reports we extracted 3,598 findings. Nearly all reports included at least one clinically unimportant finding (76/80 (95%) X-ray, 80/82 (98%) CT, 99/100 (99%) MRI). Over half of the findings (n = 2,062, 57%; 272 X-Ray, 667 CT, 1123 MRI) were judged likely clinically unimportant. Most likely clinically unimportant findings (90%, n = 1,854) were reported to be present on imaging (rather than absent) and of those only 18% (n = 331) (89 (35%) X-ray, 93 (16%) CT and 149 (15%) MRI) were explicitly reported as benign. CONCLUSION: Lumbar spine imaging reports frequently include findings unlikely to be clinically important without explicitly qualifying that they are benign.

Clinician and health service interventions to reduce the greenhouse gas emissions generated by healthcare: a systematic review.

OBJECTIVE: To synthesise the available evidence on the effects of interventions designed to improve the delivery of healthcare that reduces the greenhouse gas (GHG) emissions of healthcare. DESIGN: Systematic review and structured synthesis. SEARCH SOURCES: Cochrane Central Register of Controlled Trials, PubMed, Web of Science and Embase from inception to 3 May 2023. SELECTION CRITERIA: Randomised, quasi-randomised and non-randomised controlled trials, interrupted time series and controlled or uncontrolled before-after studies that assessed interventions primarily designed to improve the delivery of healthcare that reduces the GHG emissions of healthcare initiated by clinicians or healthcare services within any setting. MAIN OUTCOME MEASURES: Primary outcome was GHG emissions. Secondary outcomes were financial costs, effectiveness, harms, patient-relevant outcomes, engagement and acceptability. DATA COLLECTION AND ANALYSIS: Paired authors independently selected studies for inclusion, extracted data, and assessed risk of bias using a modified checklist for observational studies and the certainty of the evidence using Grades of Recommendation, Assessment, Development and Evaluation. Data could not be pooled because of clinical and methodological heterogeneity, so we synthesised results in a structured summary of intervention effects with vote counting based on direction of effect. RESULTS: 21 observational studies were included. Interventions targeted delivery of anaesthesia (12 of 21), waste/recycling (5 of 21), unnecessary test requests (3 of 21) and energy (1 of 21). The primary intervention type was clinician education. Most (20 of 21) studies were judged at unclear or high risk of bias for at least one criterion. Most studies reported effect estimates favouring the intervention (GHG emissions 17 of 18, costs 13 of 15, effectiveness 18 of 20, harms 1 of 1 and staff acceptability 1 of 1 studies), but the evidence is very uncertain for all outcomes (downgraded predominantly for observational study design and risk of bias). No studies reported patient-relevant outcomes other than death or engagement with the intervention. CONCLUSIONS: Interventions designed to improve the delivery of healthcare that reduces GHG emissions may reduce GHG emissions and costs, reduce anaesthesia use, waste and unnecessary testing, be acceptable to staff and have little to no effect on energy use or unintended harms, but the evidence is very uncertain. Rigorous studies that measure GHG emissions using gold-standard life cycle assessment are needed as well as studies in more diverse areas of healthcare. It is also important that future interventions to reduce GHG emissions evaluate the effect on beneficial and harmful patient outcomes. PROSPERO REGISTRATION NUMBER: CRD42022309428.

Referral Patterns for People With Musculoskeletal Complaints in General Practice: An Analysis From an Australian Primary Care Database.

OBJECTIVE: Our objective was to examine referral patterns for people with musculoskeletal complaints presenting to Australian general practitioners (GPs). METHODS: This longitudinal analysis from the Population Level Analysis Reporting (POLAR) database includes 133,279 patients with low back (≥18 years old) or neck, shoulder, and/or knee (≥45 years old) complaints seen by 4,538 GPs across 269 practices from 2014 through 2018. Referrals to allied health and medical and/or surgical specialists were included. We determined the number of patients with referrals and GPs who made referrals and examined their timing, associations, and trends over time. RESULTS: A total of 43,666 patients (33%) received and 3,053 GPs (67%) made at least one referral. Most referrals were to allied health (n = 25,830, 19%), followed by surgeons (n = 18,805, 14%). Surgical referrals were higher for knee complaints (n = 6,140, 24%) compared with low back, neck, and shoulder complaints (range 8%-15%). The referral category varied predominantly by body region followed by gender, socioeconomic status, and primary health network. Time to allied health referral ranged between median (interquartile range [IQR]) 14 days (0-125 days) for neck complaints and 56 days (5-177 days) for knee complaints. Surgical referrals occurred sooner for those with knee complaints (15 days, IQR 0-128 days). There was a 2.2% (95% confidence interval [CI] 1.9%-2.4%) annual increase in the proportion of allied health referrals and a 1.9% (95% CI 1.6%-2.1%) decrease in surgical referrals across all sites. CONCLUSION: One-third of patients receive, and two-thirds of GPs make, referrals for musculoskeletal complaints. Understanding the reasons for referral and differences between GPs who refer more and less frequently may identify factors that explain variations in practice.

Evolving and evaluating the OMERACT fellows program: insights and implications from OMERACT 2023 fellows.

OBJECTIVE: To describe the evolution of the OMERACT Fellows Program (OM FP) and to evaluate the innovative changes implemented in the 2023 program. METHODS: The OM FP, the first of its kind in global rheumatology, was developed in 2000 to mentor early career researchers in methods and processes for reaching evidence-driven consensus for outcome measures in clinical studies. The OM FP has evolved through continuing iterations of face to face and online feedback. Key new features delivered in 2023 included e-learning modules, virtual introductory pre-meetings, increased networking with Patient Research Partners (PRPs), learning opportunities to give and receive personal feedback, ongoing performance feedback during the meeting from Fellow peers, PRPs, senior OMERACTers (members of the OMERACT community) and Emerging Leader mentors, involvement in pitching promotions, two-minute Lightning Talks in a plenary session and an embedded poster tour. An online survey was distributed after the meeting to evaluate the program. RESULTS: OM FP has included 208 fellows from 16 countries across 4 continents covering 47 different aspects of rheumatology outcomes since its inception. Over 50 % have remained engaged with OMERACT work. In 2023, 18 Fellows attended and 15 (83 %) completed the post-meeting survey. A dedicated OM FP was deemed important by all respondents, and 93 % would attend the meeting in future. The PRP/Fellow Connection Carousel and Lightning Talks were rated exceptional by 93 %. Key components to improve included clarification of expectations, overall workload, the Emerging Leaders Mentoring Program, and the content and duration of daily summary sessions. CONCLUSION: The innovations in the 2023 OM FP were well received by the majority of participants and supports early career rheumatology researchers to develop collaborations, skills and expertise in outcome measurement. Implementation of feedback from Fellows will enhance the program for future meetings, continuing to facilitate learning and succession planning within OMERACT.

Prevalence and characteristics of musculoskeletal complaints in primary care: an analysis from the population level and analysis reporting (POLAR) database.

BACKGROUND: Electronic health record datasets have been used to determine the prevalence of musculoskeletal complaints in general practice but not to examine the associated characteristics and healthcare utilisation at the primary care level. AIM: To describe the prevalence and characteristics of patients presenting to general practitioners with musculoskeletal complaints. DESIGN AND SETTING: A five-year analysis within three Primary Health Networks (PHNs) in Victoria, Australia. METHOD: We included patients with at least one face-to-face consultation 2014 to 2018 inclusive and a low back (≥ 18 years), and/or neck, shoulder or knee (≥ 45 years) complaint determined by SNOMED codes derived from diagnostic text within the medical record. We determined prevalence, socio-demographic characteristics and diagnostic codes for patients with an eligible diagnosis; and number of consultations within one year of diagnosis. RESULTS: 324,793/1,294,021 (25%) presented with at least one musculoskeletal diagnosis, of whom 41% (n = 133,279) fulfilled our inclusion criteria. There were slightly more females (n = 73,428, 55%), two-thirds (n = 88,043) were of working age (18-64 years) and 83,816 (63%) had at least one comorbidity. Over half had a low back diagnosis (n = 76,504, 57%) followed by knee (n = 33,438, 25%), shoulder (n = 26,335, 20%) and neck (n = 14,492, 11%). Most codes included 'pain' and/or 'ache' (low back: 58%, neck: 41%, shoulder: 32%, knee 26%). Median (IQR) all-cause consultations per patient within one year of diagnosis was 7 (4-12). CONCLUSION: The burden of MSK complaints at the primary care level is high as evidenced by the prevalence of people with musculoskeletal complaints presenting to a general practitioner, the preponderance of comorbidities and the numerous consultations per year. Identification and evaluation of strategies to reduce this burden are needed.

Patterns of Imaging Requests By General Practitioners for People With Musculoskeletal Complaints: An Analysis From a Primary Care Database.

OBJECTIVE: The aim of this study was to examine imaging requested by general practitioners (GPs) for patients with low back, neck, shoulder, and knee complaints over 5 years (2014-2018). METHODS: This analysis from the Australian Population Level Analysis and Reporting database included patients presenting with a diagnosis of low back, neck, shoulder, and/or knee complaints. Eligible imaging requests included low back and neck x-ray, computed tomography (CT), and magnetic resonance imaging (MRI); knee x-ray, CT, MRI, and ultrasound; and shoulder x-ray, MRI, and ultrasound. We determined number of imaging requests and examined their timing, associated factors, and trends over time. Primary analysis included imaging requests from 2 weeks before diagnosis to 1 year after diagnosis. RESULTS: There were 133,279 patients (57% low back, 25% knee, 20% shoulder, and 11% neck complaints). Imaging was most common among those with a shoulder (49%) complaint, followed by knee (43%), neck (34%), and low back complaints (26%). Most requests occurred simultaneously with the diagnosis. Imaging modality varied by body region and, to a lesser extent, by gender, socioeconomic status, and primary health network. For low back, there was a 1.3% (95% confidence interval [95% CI] 1.0-1.6) annual increase in proportion of MRI and a concomitant 1.3% (95% CI 0.8-1.8) decrease in CT requests. For neck, there was a 3.0% (95% CI 2.1-3.9) annual increase in proportion of MRI and a concomitant 3.1% (95% CI 2.2-4.0) decrease in x-ray requests. CONCLUSION: GPs commonly request early diagnostic imaging for musculoskeletal complaints at odds with recommended practice. We observed a trend towards more complex imaging for neck and back complaints.

Cohort profile: Using primary care data to understand Opioid Prescribing, Policy Impacts and Clinical Outcomes (OPPICO) in Victoria, Australia.

PURPOSE: The OPPICO cohort is a population-based cohort based on non-identifiable electronic health records routinely collected from 464 general practices in Victoria, Australia, created with the aim of understanding opioid prescribing, policy impacts and clinical outcomes. The aim of this paper is to provide a profile of the study cohort by summarising available demographic, clinical and prescribing characteristics. PARTICIPANTS: The cohort described in this paper comprises people who were aged at least 14 years at cohort entry, and who were prescribed an opioid analgesic at least once at participating practices for a total of 1 137 728 person-years from 1 January 2015 to 31 December 2020. The cohort was formed using the data collected from electronic health records through the Population Level Analysis and Reporting (POLAR) system. The POLAR data primarily consist of patient demographics, clinical measurements, Australian Medicare Benefits Scheme item numbers, diagnoses, pathology testing and prescribed medications. FINDING TO DATE: In total, the cohort consists of 676 970 participants with 4 389 185 opioid prescription records from 1 January 2015 to 31 December 2020. Approximately half (48.7%) received a single opioid prescription, and 0.9% received more than 100 opioid prescriptions. The mean number of opioid prescriptions per patient was 6.5 (SD=20.9); prescriptions for strong opioids accounted for 55.6% of all opioid prescriptions. FUTURE PLANS: The OPPICO cohort data will be used for various types of pharmacoepidemiological research, including examining the impact of policy changes on coprescription of opioids with benzodiazepines and gabapentin, and monitoring trends and patterns of other medication utilisation. Through data-linkage between our OPPICO cohort and hospital outcome data, we will examine whether policy changes for opioid prescribing lead to changes in prescription opioid-related harms, and other drug and mental health-related outcomes.

Breakeven, cost benefit, cost effectiveness, and willingness to pay for web-based versus face-to-face education delivery for health professionals.

BACKGROUND: The introduction of Web-based education and open universities has seen an increase in access to professional development within the health professional education marketplace. Economic efficiencies of Web-based education and traditional face-to-face educational approaches have not been compared under randomized controlled trial conditions. OBJECTIVE: To compare costs and effects of Web-based and face-to-face short courses in falls prevention education for health professionals. METHODS: We designed two short courses to improve the clinical performance of health professionals in exercise prescription for falls prevention. One was developed for delivery in face-to-face mode and the other for online learning. Data were collected on learning outcomes including participation, satisfaction, knowledge acquisition, and change in practice, and combined with costs, savings, and benefits, to enable a break-even analysis from the perspective of the provider, cost-effectiveness analysis from the perspective of the health service, and cost-benefit analysis from the perspective of the participant. RESULTS: Face-to-face and Web-based delivery modalities produced comparable outcomes for participation, satisfaction, knowledge acquisition, and change in practice. Break-even analysis identified the Web-based educational approach to be robustly superior to face-to-face education, requiring a lower number of enrollments for the program to reach its break-even point. Cost-effectiveness analyses from the perspective of the health service and cost-benefit analysis from the perspective of the participant favored face-to-face education, although the outcomes were contingent on the sensitivity analysis applied (eg, the fee structure used). CONCLUSIONS: The Web-based educational approach was clearly more efficient from the perspective of the education provider. In the presence of relatively equivocal results for comparisons from other stakeholder perspectives, it is likely that providers would prefer to deliver education via a Web-based medium.

The effect of transferring weekend physical therapy services from the acute to sub-acute setting in patients following hip and knee arthroplasty: a quasi-experimental study.

BACKGROUND: Weekend physical therapy services in the acute and/or sub-acute setting may optimize postoperative recovery following hip and knee arthroplasty, though evidence supporting these services is limited. PURPOSE: To explore the change in patient and service outcomes of transferring a weekend physical therapy service from the acute to the sub-acute setting following hip and knee arthroplasty. METHODS: This was a quasi-experimental research design nested within two stepped-wedge cluster randomized controlled trials. Acute weekend physical therapy services were sequentially discontinued and reallocated to the sub-acute setting in a random order from one ward at a time within the broader trial. Patient and service outcomes for participants 6 weeks following hip and knee arthroplasty (N = 247) were compared during 6 months of acute weekend physical therapy services (Phase 1, n = 117) followed by 6 months of sub-acute services (Phase 2, n = 130). Intention-to-treat statistical analyses were conducted. RESULTS: The intervention had a negligible effect on medium-term outcomes. The only statistically significant difference observed was slightly higher ratings of "worst pain experienced over the past week" [coefficient 0.865 (0.123 to 1.606), p = .022] during Phase 2. No interaction effects were observed despite a 2.4-day reduction in length of stay amongst complex patients during Phase 2 (18.28 and 15.86 days in Phase 1 and 2, respectively). CONCLUSIONS: No comparative advantage or disadvantage was observed by reallocating a weekend physical therapy budget from the acute to sub-acute setting following hip and knee arthroplasty. Further research investigating the cost-effectiveness of these services in the sub-acute setting may be warranted for complex patients.

The environmental impact of health care for musculoskeletal conditions: A scoping review.

BACKGROUND: Health care has significant environmental impact. We performed a scoping review to map what is known about the environmental impact of health care for musculoskeletal conditions. METHODS: We included published papers of any design that measured or discussed environmental impact of health care or health support services for any musculoskeletal condition in terms of climate change or global warming (e.g., greenhouse gas emissions it produces). We searched MEDLINE and Embase from inception to 2 May 2022 using keywords for environmental health and musculoskeletal conditions, and performed keyword searches using Google and Google Scholar. Two independent reviewers screened studies. One author independently charted data, verified by a second author. A narrative synthesis was performed. RESULTS: Of 12,302 publications screened and 73 identified from other searches, 122 full-text articles were assessed for eligibility, and 49 were included (published 1994 to 2022). Of 24 original research studies, 11 measured environmental impact relating to climate change in orthopaedics (n = 10), and medical aids for the knee (n = 1), one measured energy expenditure of laminar versus turbulent airflow ventilation systems in operating rooms during simulated hip replacements and 12 measured waste associated with orthopaedic surgery but did not relate waste to greenhouse gas emissions or environmental effects. Twenty-one editorials described a need to reduce environmental impact of orthopaedic surgery (n = 9), physiotherapy (n = 9), podiatry (n = 2) or occupational therapy (n = 1). Four narrative reviews discussed sustainability relating to hand surgery (n = 2), orthopaedic surgery (n = 1) and orthopaedic implants (n = 1). CONCLUSION: Despite an established link between health care and greenhouse gas emissions we found limited empirical data estimating the impact of musculoskeletal health care on the environment. These data are needed to determine whether actions to lower the carbon footprint of musculoskeletal health care should be a priority and to identify those aspects of care that should be prioritised.

Effectiveness of Web-based versus face-to-face delivery of education in prescription of falls-prevention exercise to health professionals: randomized trial.

BACKGROUND: Exercise is an effective intervention for the prevention of falls; however, some forms of exercises have been shown to be more effective than others. There is a need to identify effective and efficient methods for training health professionals in exercise prescription for falls prevention. OBJECTIVE: The objective of our study was to compare two approaches for training clinicians in prescribing exercise to prevent falls. METHODS: This study was a head-to-head randomized trial design. Participants were physiotherapists, occupational therapists, nurses, and exercise physiologists working in Victoria, Australia. Participants randomly assigned to one group received face-to-face traditional education using a 1-day seminar format with additional video and written support material. The other participants received Web-based delivery of the equivalent educational material over a 4-week period with remote tutor facilitation. Outcomes were measured across levels 1 to 3 of Kirkpatrick's hierarchy of educational outcomes, including attendance, adherence, satisfaction, knowledge, and self-reported change in practice. RESULTS: Of the 166 participants initially recruited, there was gradual attrition from randomization to participation in the trial (n = 67 Web-based, n = 68 face-to-face), to completion of the educational content (n = 44 Web-based, n = 50 face-to-face), to completion of the posteducation examinations (n = 43 Web-based, n = 49 face-to-face). Participant satisfaction was not significantly different between the intervention groups: mean (SD) satisfaction with content and relevance of course material was 25.73 (5.14) in the Web-based and 26.11 (5.41) in the face-to-face group; linear regression P = .75; and mean (SD) satisfaction with course facilitation and support was 11.61 (2.00) in the Web-based and 12.08 (1.54) in the face-to-face group; linear regression P = .25. Knowledge test results were comparable between the Web-based and face-to-face groups: median (interquartile range [IQR]) for the Web-based group was 90.00 (70.89-90.67) and for the face-to-face group was 80.56 (70.67-90.00); rank sum P = .07. The median (IQR) scores for the exercise assignment were also comparable: Web-based, 78.6 (68.5-85.1), and face-to-face, 78.6 (70.8-86.9); rank sum P = .61. No significant difference was identified in Kirkpatrick's hierarchy domain change in practice: mean (SD) Web-based, 21.75 (4.40), and face-to-face, 21.88 (3.24); linear regression P = .89. CONCLUSION: Web-based and face-to-face approaches to the delivery of education to clinicians on the subject of exercise prescription for falls prevention produced equivalent results in all of the outcome domains. Practical considerations should arguably drive choice of delivery method, which may favor Web-based provision for its ability to overcome access issues for health professionals in regional and remote settings.
