Serum Vitamin D and Chronic Musculoskeletal Pain: A Cross-Sectional Study of 349,221 Adults in the UK.

Insufficient and deficient vitamin D may be associated with chronic musculoskeletal pain, but study findings are conflicting, and few account for important confounding factors. This cross-sectional study explored the association between serum vitamin D status and chronic musculoskeletal pain in various body sites, adjusting for a wide range and a number of potential confounding factors. Data collected at the baseline assessments of 349,221 UK Biobank participants between 2006 and 2010 were analyzed. Serum 25-hydroxyvitamin D was measured and categorized as <25.0 nmol/L (severe deficiency), 25.0 to 49.9 nmol/L (deficiency), 50.0 to 74.9 nmol/L (insufficiency), and ≥75.0 nmol/L (sufficiency). The outcome was self-reported chronic musculoskeletal pain at any site, neck/shoulder, back, hip, knee, or widespread pain that interfered with usual activities. Potential confounders were identified using directed acyclic graphs and included sociodemographic, lifestyle, psychological factors, and medical comorbidities. Simple models adjusted for age and sex showed significant associations between suboptimal vitamin D status and chronic pain across all sites (odds ratios [ORs] ranged 1.07-2.85). These associations were weakened or became insignificant after accounting for all confounding factors (ORs ≤ 1.01) for chronic regional musculoskeletal pain. Severe vitamin D deficiency remained a significant and positive association with chronic widespread pain after adjusting for all confounding factors (OR [95% confidence interval]: 1.26 [1.07, 1.49]). This study suggests that, while vitamin D status is not a key independent determinant of chronic regional musculoskeletal pain, severe vitamin D deficiency may be associated with chronic widespread pain. PERSPECTIVES: After accounting for various confounders, vitamin D deficiency was not associated with regional musculoskeletal pain. However, the relationship between chronic widespread pain severe vitamin D deficiency remained after confounder adjustment. Use of vitamin D supplements in individuals with chronic widespread pain and severe vitamin D deficiency warrants further exploration.

C-Reactive Protein (CRP) is Associated With Chronic Pain Independently of Biopsychosocial Factors.

Inflammation is linked with chronic pain but the extent to which this relationship is associated with biopsychosocial factors is not known. We investigated relationships between blood C-reactive protein (CRP) and regional chronic pain conditions adjusting for a large range and number of potential confounders. We performed cross-sectional analyses using the UK Biobank (N = 415,567) comparing CRP in people reporting any of 9 types of regional chronic pain with pain-free controls. Using logistic regression modelling, we explored relationships between CRP and the presence of chronic pain, with demographic, socioeconomic, psychological/lifestyle factors, and medical comorbidities as covariates. CRP was higher in chronic pain at any site compared with controls (Females: median [interquartile range] 1.60 mg/L [2.74] vs 1.17 mg/L [1.87], P < .001; Males: 1.44 mg/L [2.12] vs 1.15 mg/L [1.65], P < .001). In males, associations between CRP and all types of chronic pain were attenuated but remained significant after adjustment for biopsychosocial covariates (OR range 1.08-1.49, P ≤ .001). For females, adjusted associations between CRP and pain remained significant for most chronic pain types (OR range 1.07-1.34, P < .001) except for facial pain (OR 1.04, P = .17) and headache (OR 1.02, P = .07)-although these non-significant findings may reflect reduced sample size. The significant association between CRP and chronic pain after adjustment for key biopsychosocial confounders implicates an independent underlying biological mechanism of inflammation in chronic pain. The presence of yet unknown or unmeasured confounding factors cannot be ruled out. Our findings may inform better-targeted treatments for chronic pain. PERSPECTIVE: Using a large-scale dataset, this article investigates associations between chronic pain conditions and blood C-reactive protein (CRP), to evaluate the confounding effects of a range of biopsychosocial factors. CRP levels were higher in those with chronic pain versus controls after adjusting for confounders-suggesting a possible independent biological mechanism.

Objectively and subjectively measured physical activity levels in individuals with whiplash associated disorder and aged-matched healthy controls.

BACKGROUND: Whiplash associated disorders (WAD) are the most common non-hospitalised injuries resulting from a motor vehicle crash. Half of individuals with WAD experience ongoing pain and disability. Furthermore, individuals with persistent WAD have lower levels of aerobic capacity and isometric strength compared with age-matched controls. It is not known whether these differences are associated with increased levels of pain and disability, or with reduced physical activity (PA) participation. OBJECTIVE: Our primary aim was to compare PA levels in individuals with persistent WAD with healthy controls. Secondary aims were to: compare objective and subjective measurements of PA; explore factors that may influence PA; and describe proportions of these populations meeting World Health Organisation PA guidelines. METHODS: Objective (ActiGraph accelerometer; seven days) and subjective (International Physical Activity Questionnaire (IPAQ)) PA data were collected for n = 53 age-matched participants (WAD n = 28; controls n = 25). RESULTS: Independent sample t-tests showed no significant difference in objectively measured PA (p>0.05) between WAD and controls. For the subjective measure (IPAQ), controls reported more overall weekly PA (t = 0.219, p<0.05), while WAD participants reported more weekly walking minutes (t = -0.712, p<0.05). Linear regression showed mental health quality-of-life predicted objectively measured moderate intensity PA (R2 = 0.225, F (2, 44) = 6.379, p<0.004) and subjectively reported overall PA (R2 = 0.132, F (1, 41) = 6.226, p<0.017). Bland-Altman analyses indicated that subjects over-reported MVPA and under-reported sedentary time using the IPAQ. CONCLUSIONS: Individuals with WAD had levels of physical and mental health quality-of-life significantly lower than controls and below population norms yet participated in similar levels of PA. Given that increased perceptions of mental health quality-of-life were positively associated with objectively measured MVPA and subjectively reported overall PA, strategies to help people with WAD achieve adequate doses of MVPA may be beneficial. ActiGraph-measured and IPAQ-reported PA were discordant. Hence, IPAQ may not be a reliable measure of habitual PA in WAD.

Implementation of a risk-stratified, guideline-based clinical pathway of care to improve health outcomes following whiplash injury (Whiplash ImPaCT): a multicentre, randomized, controlled trial.

ABSTRACT: Current pathways of care for whiplash follow a "stepped care model," result in modest treatment outcomes and fail to offer efficient management solutions. This study aimed to evaluate the effectiveness of a risk-stratified clinical pathway of care (CPC) compared with usual care (UC) in people with acute whiplash. We conducted a multicentre, 2-arm, parallel, randomised, controlled trial in primary care in Australia. Participants with acute whiplash (n = 216) were stratified for risk of a poor outcome (low vs medium/high risk) and randomised using concealed allocation to either the CPC or UC. In the CPC group, low-risk participants received guideline-based advice and exercise supported by an online resource, and medium-risk/high-risk participants were referred to a whiplash specialist who assessed modifiable risk factors and then determined further care. The UC group received care from their primary healthcare provider who had no knowledge of risk status. Primary outcomes were neck disability index (NDI) and Global Rating of Change (GRC) at 3 months. Analysis blinded to group used intention-to-treat and linear mixed models. There was no difference between the groups for the NDI (mean difference [MD] [95% confidence interval (CI)] -2.34 [-7.44 to 2.76]) or GRC (MD 95% CI 0.08 [-0.55 to 0.70]) at 3 months. Baseline risk category did not modify the effect of treatment. No adverse events were reported. Risk-stratified care for acute whiplash did not improve patient outcomes, and implementation of this CPC in its current form is not recommended.

A cost-minimisation analysis comparing alternative telemedicine screening approaches for retinopathy of prematurity.

INTRODUCTION: Screening for retinopathy of prematurity (ROP) is an important procedure in the prevention of blindness in high-risk preterm infants. In the regionalised healthcare system of Queensland (Australia), outside of the major centres, some preterm infants are cared for in special care nurseries (SCNs). When necessary, infants in these nurseries who are at risk of ROP are transferred to a tertiary hospital for screening by paediatric ophthalmologists. The transport of preterm infants for eye examinations adds risk and incurs significant costs to the health system. Using a cost-minimisation approach, we aimed to compare the costs of the current ROP screening practice with two alternative telemedicine approaches. METHODS: We constructed a decision analytic model to estimate costs from a health service perspective with a five-year analysis horizon; activity data from a tertiary ROP screening service were used to inform the models. The three models assessed were: (a) a digital retinal photography (DRP)-equipped travelling nurse, (b) equipping SCNs with DRP, and providing training to local nurses, and (c) current practice of infant transfer. In all cases, the tertiary centre provides specialist ophthalmologic review. RESULTS: Of the three models, we estimated the most expensive option to be equipping SCNs with DRP and providing training to local nurses (AUD$4114/infant). We found that the current practice of transferring infants was the second most expensive (AUD$1021/infant). The most economical model was the specialist nurse travelling to each SCN with a portable DRP (AUD$363/infant). A sensitivity analysis, which assessed uncertainty and variability around the cost estimates, found that the ranking for the expected costs of the alternative models of care did not change. DISCUSSION: This is the first economic and cost-minimisation analysis in Australia to compare the costs of the current screening programme with two alternative telemedicine approaches for screening ROP. Telemedicine programmes that facilitate non-physician screening may improve the cost efficiency of the health system while maintaining the health outcomes for children, and reducing the risk associated with infant transport.

The Origins and Evolution of the Field of Masculinity and Suicide: A Bibliometric and Content Analysis of the Research Field.

BACKGROUND: In most countries, men complete suicide at twice the rate of women; masculinity plays an important role in placing men at a greater risk of suicide. This study identifies and describes trends in the topics discussed within the masculinity and suicide literature and explores changes over time. METHODS: We retrieved publications relating to masculinity and suicide from eight electronic databases and described origins in the field of research by reference to the first decade of publications. We then explored the subsequent evolution of the field by analysis of the content of article titles/abstracts for all years since the topic first emerged, and then separately by three epochs. RESULTS: We included 452 publications (1954-2021); research output has grown substantially in the last five years. Early publications framed suicide in the context of severe mental illness, masculinity as a risk factor, and suicidality as being aggressive and masculine. We observed some differences in themes over time: Epoch 1 focused on sex differences in suicidality, a common theme in epochs 2 was relationship to work and its effect on men's mental health and suicidality, and epoch 3 had a focus on help-seeking in suicidality. CONCLUSION: The research field of masculinity and suicide is growing strongly, as evidenced by recent increase in publication volume. The structure, content and direction of the masculinity and suicide research are still evolving. Researchers must work with policymakers and practitioners to ensure that emerging findings are translated for use in programs designed to address suicide in boys and men.HIGHLIGHTSMasculinity and suicide as a field is not new, with its origins in the literature dating back to 1954.More than half of the total research output in the field (1954-2021) has been published in the last five years.Early work focused on individual-level risk factors to male suicide (e.g., severe mental illness), while contemporary research focused on social and cultural determinants of male suicide (e.g., help-seeking).

Medical students' perceptions and expectations regarding digital health education and training: A qualitative study.

INTRODUCTION: Digital health - the convergence of digital technologies within health and health care to enhance the efficiency of health-care delivery - is fast becoming an integral part of routine medical practice. The integration of digital health into traditional practice brings significant changes. Logic dictates that for medical practitioners to operate in this new digitally enabled environment, they require specific knowledge, skills and competencies relating to digital health. However, very few medical programmes in Australia and globally include digital health within their regular curriculum. This pilot study aimed to explore medical students' perceptions and expectations of digital health education and training (ET). METHODS: An online survey and focus groups were used to collect information about medical students' perceptions and expectations relating to digital health and ET relating to this field within the medical programme at the University of Queensland. Sixty-three students took part in the survey, and 17 students were involved in four focus groups. RESULTS: Most participants had no formal ET in digital health. Most participants (n = 43; 68%) expressed a willingness to learn about digital health as part of their medical programme. DISCUSSION: Primarily, knowledge- and practice-related factors have motivated students to learn about digital health. The analysis of focus group data identified two superordinate themes: (a) drivers of digital health ET and (b) expectations relating to digital health ET. Students agreed that digital health is a relevant field for their future practice that should be taught as part of their regular curriculum.

Telemedicine: Niche or mainstream? A bibliometric analysis and review of the output of highly ranked clinical journals.

Historically, telemedicine research is predominantly published in discipline-specific telemedicine journals. However, in recent times the number of publications on telemedicine in clinical journals has increased. Acceptance of telemedicine research by clinical journals indicates a maturing of the telemedicine field. This bibliometric study reviewed telemedicine-related literature published in clinical journals from 2008 to 2018. A search was conducted in PubMed using two types of clinical outlets. (1) Top 20 journals with highest Impact Factor in the field of Medicine. (2) Top five journals with highest Impact Factor in most common Medical Specialty Areas. Analysis showed that there is a steady growth of literature relating to research and non-research publications appearing in clinical journals. Top five journals in the field of Medicine - BMJ, JAMA, Cochrane database, Medical Journal of Australia and Lancet have published 64% (n = 270) of telemedicine-related articles for the study period. Disease areas associated with telemedicine publications are consistent with global disease priorities. The review demonstrated that the most significant increase in telemedicine research published in clinical journals was focused on patient care.

Development and use of mobile messaging for individuals with musculoskeletal pain conditions: a scoping review protocol.

INTRODUCTION: Previous reviews of mobile messaging for individuals with musculoskeletal pain have shown positive effects on pain and disability. However, the configuration of digital content, method of presentation and interaction, dose and frequency needed for optimal results remain unclear. Patient preferences concerning such systems are also unclear. Addressing these knowledge gaps, incorporating evidence from both experimental and observational studies, may be useful to understand the extent of the relevant literature, and to influence the design and outcomes of future messaging systems. We aim to map information that could be influential in the design of future mobile messaging systems for individuals with musculoskeletal pain conditions, and to summarise the findings of efficacy, effectiveness, and economics derived from both experimental and observational studies. METHODS AND ANALYSIS: We will include studies describing the development and/or use of mobile messaging to support adults (≥18 years) with acute or chronic musculoskeletal pain. We will exclude digital health studies that lack a mobile messaging component, or those targeted at other health conditions unrelated to the bones, muscles and connective tissues, or involving surgical or patients with cancer, or studies involving solely healthy individuals. Our sources of information will be online databases and reference lists of relevant papers. We will include papers published in English in the last 10 years. Two pairs of independent reviewers will screen, select and extract the data, with any disagreements mediated by a third reviewer. We will report the results according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews checklist. We will synthesise the findings in a tabular format and provide a descriptive summary. ETHICS AND DISSEMINATION: Formal ethical approval is not required. We will disseminate the findings through publication in a peer-reviewed journal, relevant conferences, and relevant consumer forums.

Weight and weight control behaviors during long-term endometrial cancer survivorship: Results of the Laparoscopic Approach to Cancer of the Endometrium long-term follow-up study.

BACKGROUND: Overweight or obesity is common in endometrial cancer (EC). This study aimed to examine sociodemographic, clinical, and psychosocial characteristics associated with being discontent with current weight and use of weight control methods among long-term EC survivors. METHODS: Women diagnosed with early-stage EC who participated in the Laparoscopic Approach to Cancer of the Endometrium (LACE) trial (n = 516) were invited to complete a long-term follow-up survey at least 4.5 years after treatment. Chi-square test and multivariate logistic regression models adjusted for time since surgery were used to determine factors associated with being discontent with current weight. RESULTS: On average 9 years after surgery, 190/259 (73%) of participants were currently discontent with their weight, and 146 (56%) had used one or more weight loss methods during the past 12 months. Women who were discontent with their weight were more likely to be younger than 70 years (p < 0.000), and used one or more weight loss methods ever or during the past 12 months (p < 0.000). Among the weight loss methods used, exercise (40.1%), meal reductions (52.7%), or fat/sugar reductions (48.5%) were much more commonly reported than fasting (2.6%) or designated weight loss programs (2.3%). CONCLUSIONS: Our study provides evidence that the majority of long-term EC survivors in this clinical trial population are discontent with their weight and over half continue to use multiple methods to lose weight each year. These data indicate that health professionals and lifestyle educators need to assess weight issues, and develop a tailored plan to address the specific needs of long-term survivors to assist them become content with their weight after treatment for EC.

A randomised controlled trial of implementation of a guideline-based clinical pathway of care to improve health outcomes following whiplash injury (Whiplash ImPaCT): Statistical analysis plan.

BACKGROUND: Statistical analysis plans describe the processes of data handling and analysis in clinical trials; by doing so they increase the transparency of the analysis and reporting of studies. This paper reports the planned statistical analysis plan for the Whiplash ImPaCT study. For individuals with whiplash injury, Whiplash ImPaCT aims to assess the effectiveness of a guidelines-based clinical pathway of care compared with usual care. METHODS: We report the planned procedures, methods, and reporting for the primary and secondary analyses of the Whiplash ImPaCT study. The primary outcomes are Global Recovery and Neck Disability Index at 3 months post-randomisation. Outcomes will be analysed according to the intention to treat principle using linear mixed models. A cost-utility analysis will be conducted to compute the incremental cost-effectiveness of the intervention to usual care. We describe data handling, our analytical approach, assumptions about missing data, and our planned methods of reporting. DISCUSSION: This paper will provide a detailed description of the planned analyses for the Whiplash ImPaCT trial.

Long-term quality of life outcomes of women treated for early-stage endometrial cancer.

OBJECTIVE: To compare long-term quality of life in women treated for early-stage endometrial cancer with population norms, and to compare quality of life outcomes of patients who had total laparoscopic or total abdominal hysterectomy. METHODS: Once the last enrolled patient had completed 4.5 years of follow-up after surgery, participants in the Laparoscopic Approach to Cancer of the Endometrium (LACE) clinical trial were asked to complete a self-administered questionnaire. Two instruments-EuroQol 5 Dimension 3-level (EQ-5D-3L) and the Functional Assessment of Cancer Treatment-General Population (FACT-GP)-were used to determine quality of life. The mean computed EQ-5D-3L index scores for LACE participants at different age categories were compared with Australian normative scores; and the FACT-GP scores were compared between patients treated with surgical treatments. RESULTS: Of 760 women originally enrolled in the LACE trial, 259 (50.2%) of 516 women consented to provide long-term follow-up data at a median of 9 years (range 6-12) after surgery. On the EQ-5D-3L, long-term endometrial cancer survivors reported higher prevalence of anxiety/depression than normative levels across all age groups (55-64 years, 30% vs 14.9%; 65-74 years, 30.1% vs 15.8%; ≥75 years, 25.9% vs 10.7%). For women ≥75 years of age, the prevalence of impairment in mobility (57.6% vs 43.3%) and usual activities (58.8% vs 37.9%) was also higher than for population norms. For the FACT-GP, the physical (effect size: -0.28, p<0.028) and functional (effect size: -0.30, p<0.015) well-being sub-scale favored the total laparoscopic hysterectomy compared with total abdominal hysterectomy recipients. CONCLUSION: Compared with population-based norms, long-term endometrial cancer survivors reported higher prevalence of anxiety/depression across all age groups, and deficits in mobility and usual activities for women aged ≥75 years. Physical and functional well-being were better among women who were treated with total laparoscopic hysterectomy than among those receiving total abdominal hysterectomy.

Trauma-focused cognitive behavioural therapy and exercise for chronic whiplash with comorbid posttraumatic stress disorder: a randomised controlled trial.

ABSTRACT: Many people with chronic whiplash-associated disorders (WAD) have also symptoms of posttraumatic stress disorder (PTSD), but this is rarely considered in usual predominantly exercise-based interventions. We aimed to investigate the effectiveness of combined trauma-focused cognitive behavioural therapy (TF-CBT) and exercise compared with supportive therapy (ST) and exercise for people with chronic WAD and PTSD. A randomised controlled multicentre trial with concealed allocation, assessor blinding, and blinded analysis was conducted. One hundred three participants with chronic WAD (>3 months and <5 years, grade II) and PTSD were randomised to TF-CBT and exercise (n = 53) or ST and exercise (n = 50). Both interventions comprised 10 weeks of TF-CBT or ST, followed by 6 weeks of exercise. Outcomes were measured at baseline, 10, 16 weeks, 6, and 12 months after randomisation. Analysis was intention to treat using linear mixed models. There was no difference between the interventions on the primary outcome of neck pain-related disability at any time point. At 16 weeks, the treatment effect on the 0 to 100 Neck Disability Index was 0.59 (95% confidence interval [CI] 5.51 to -4.33), at 6 months 1.18 (95% CI 6.15 to -3.78), and at 12 months 1.85 (95% CI 6.81 to -3.11). In addition, there was no difference between the interventions for most secondary outcomes at any time. Exceptions were in favour of TF-CBT and exercise, where improvements in PTSD symptoms were found at 16 weeks. From 16 weeks onwards, both groups achieved a clinically important improvement in neck pain-related disability. However, both groups remained moderately disabled.

Comparative effectiveness of physical exercise interventions for chronic non-specific neck pain: a systematic review with network meta-analysis of 40 randomised controlled trials.

OBJECTIVE: To compare the effectiveness of different physical exercise interventions for chronic non-specific neck pain. DESIGN: Systematic review and network meta-analysis. DATA SOURCES: Electronic databases: AMED, CINAHL, Cochrane Central Register of Controlled Trials, Embase, MEDLINE, Physiotherapy Evidence Database, PsycINFO, Scopus and SPORTDiscus. ELIGIBILITY CRITERIA: Randomised controlled trials (RCTs) describing the effects of any physical exercise intervention in adults with chronic non-specific neck pain. RESULTS: The search returned 6549 records, 40 studies were included. Two networks of pairwise comparisons were constructed, one for pain intensity (n=38 RCTs, n=3151 participants) and one for disability (n=29 RCTs, n=2336 participants), and direct and indirect evidence was obtained. Compared with no treatment, three exercise interventions were found to be effective for pain and disability: motor control (Hedges' g, pain -1.32, 95% CI: -1.99 to -0.65; disability -0.87, 95% CI: -1.45 o -0.29), yoga/Pilates/Tai Chi/Qigong (pain -1.25, 95% CI: -1.85 to -0.65; disability -1.16, 95% CI: -1.75 to -0.57) and strengthening (pain -1.21, 95% CI: -1.63 to -0.78; disability -0.75, 95% CI: -1.28 to -0.22). Other interventions, including range of motion (pain -0.98 CI: -2.51 to 0.56), balance (pain -0.38, 95% CI: -2.10 to 1.33) and multimodal (three or more exercises types combined) (pain -0.08, 95% CI: -1.70 to 1.53) exercises showed uncertain or negligible effects. The quality of evidence was very low according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria. CONCLUSION: There is not one superior type of physical exercise for people with chronic non-specific neck pain. Rather, there is very low quality evidence that motor control, yoga/Pilates/Tai Chi/Qigong and strengthening exercises are equally effective. These findings may assist clinicians to select exercises for people with chronic non-specific neck pain. PROSPERO REGISTRATION NUMBER: CRD42019126523.

Patient-Reported Experiences After Hysterectomy: A Cross-Sectional Study of the Views of Over 2300 Women.

OBJECTIVE: To evaluate women's experiences after hysterectomy and predictors of their contentment and regret with the surgical approaches. METHODS: Cross-sectional, Patient-Reported Experience Measures survey in 2319 Australian women aged 21 to 90 years (median age of 52 years) who had received hysterectomy in the preceding 2 years. RESULTS: Overall, the vast majority of women (>96%) did not regret having had the hysterectomy. Women who received an open abdominal hysterectomy reported slower recovery with about 7% of women still not fully recovered after 12 months compared to those whose surgery was through a less invasive approach. Women who reported no adverse events, having been given a choice of type of hysterectomy, women who received an alternative to open abdominal hysterectomy, and women who felt prepared for discharge from hospital were significantly more likely to be content with their hysterectomy and report positive patient experiences. CONCLUSIONS: Compared with those who received a less invasive approach to hysterectomy, women who received open surgery were more likely to express negative experiences relating to their hospital stay and recovery from surgery. The results inform future improvements of care for women planning a hysterectomy.

The comparative effectiveness of physical exercise interventions in individuals with chronic non-specific neck pain: protocol for a network meta-analysis.

INTRODUCTION: Neck pain is a global burdensome problem, with a large proportion of neck pain cases becoming chronic. Although physical exercise is a commonly prescribed treatment, the evidence on the effectiveness of isolated exercise interventions remains limited. Traditional pairwise randomised controlled trials (RCTs) and meta-analyses are limited in only comparing two interventions. This protocol describes the design of a network meta-analysis, which enables a comparative investigation of all physical exercise interventions for which RCTs are available. We aim to systematically compare the effectiveness of different types of physical exercise in people with chronic non-specific neck pain. METHODS AND ANALYSIS: Nine electronic databases (AMED, CINAHL, Cochrane Central Register of Controlled Trials, Embase, MEDLINE, Physiotherapy Evidence Database, PsycINFO, Scopus and SPORTDiscus) were searched for RCTs from inception to 12 March 2019. Titles and abstract firstly, and full-text papers secondly, will be screened by two reviewers. Data will be extracted by two reviewers. The primary outcome measure is effectiveness of the intervention. Methodological quality of included studies will be assessed by two reviewers using the PEDro scale. The overall quality of evidence will be assessed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework, which has been adapted for network meta-analyses. The available evidence will be summarised using a network diagram. A contribution matrix will be presented to allow assessment of direct and indirect evidence. Forest plots will be constructed to visualise effects of all included exercise interventions. Pairwise effect sizes will be calculated by including all evidence available in the network. Effect measures for treatments that have not been compared in a pairwise RCT can be compared indirectly by contrasting effect sizes of comparisons with a common comparator. ETHICS AND DISSEMINATION: This work synthesises evidence from previously published studies and does not require ethics review or approval. A manuscript describing the findings will be submitted for publication in a peer-reviewed scientific journal. PROSPERO REGISTRATION NUMBER: CRD42019126523.

Queensland Telepaediatric Service: A Review of the First 15 Years of Service.

In November 2000, the Queensland Telepaediatric Service (QTS) was established in Brisbane, Australia, to support the delivery of telehealth services to patients and clinicians in regional and remote locations. The QTS was built on a centralized coordination model, where telehealth services could be effectively managed by a dedicated telehealth coordinator. In doing so, telehealth referral and consultation processes were efficient and clinicians felt better supported as they adjusted to new processes for engaging with patients. We have conducted a retrospective review of activity associated with the QTS and summarized key activities which have arisen from this extensive program of work. Telehealth service records and associated publications were used to describe the evolution of the QTS over a 15-year period. From November 2000 to March 2016, 23,054 telehealth consultations were delivered for 37 pediatric clinical specialties. The most common service areas included child and youth mental health, neurology, burns care, surgery, and ear nose and throat services. A range of different telehealth service models were developed to align with different clinical service needs and location of services. Whilst most work involved video consultation between hospitals, some services involved the delivery of telehealth services into the home, schools or community health centres. Despite its longevity, the QTS was not immune to the usual challenges associated with telehealth implementation, service redesign and sustainability. Experience reported from the QTS will be useful for other health services seeking to develop comprehensive telehealth services in a rapidly changing healthcare environment.

The mechanisms of effect of a physiotherapist-delivered integrated psychological and exercise intervention for acute whiplash-associated disorders: secondary mediation analysis of a randomized controlled trial.

INTRODUCTION: Integrated psychological and physical treatments can improve recovery for whiplash-associated disorders (WADs). Little is known about how these interventions work. OBJECTIVE: To examine the mechanisms by which a physiotherapist-delivered integrated intervention for acute WAD improves health outcomes. METHODS: Secondary analysis using structural equation modelling of a randomized controlled trial comparing integrated stress inoculation training and exercise to exercise alone for acute WAD. Outcomes were disability, pain self-efficacy, pain intensity, and health-related quality of life at 12 months. The intended intervention target and primary mediator, stress was tested in parallel with pain-related coping, an additional cognitive behavioral mediator that significantly improved at posttreatment (Model 1). Stress-related constructs that commonly co-occur with stress and pain were also tested as parallel mediators: depression and pain-related coping (Model 2); and posttraumatic stress and pain-related coping (Model 3). RESULTS: Reductions in stress mediated the effect of the integrated intervention on disability (ß = -0.12, confidence interval [CI] = -0.21 to -0.06), pain self-efficacy (ß = 0.09, CI = 0.02-0.18), pain (ß = -0.12, CI = -0.21 to -0.06), and health-related quality of life (ß = 0.11, CI = 0.04-0.21). There was an additional path to pain self-efficacy through pain-related coping (ß = 0.06, CI = 0.01-0.12). Similar patterns were found in Models 2 and 3. CONCLUSIONS: Improvements in stress and related constructs of depression and posttraumatic stress, and pain-related coping were causal mechanisms of effect in a physiotherapist-delivered integrated intervention. As integrated interventions are growing in popularity, it is important to further personalize interventions for improved benefit.
