Frequency of a very brief intervention by physiotherapists to increase physical activity levels in adults:A pilot randomised controlled trial

Background: There is evidence that brief physical activity interventions by health professionals can increase physical activity levels. In addition, there is some evidence that simply measuring physical activity alone can increase physical activity behaviour. However, preliminary work is required to determine the effects of potential measurement frequency. The aim of this pilot study was to examine whether frequency of physical activity measurement, with very brief advice from a physiotherapist, influenced objectively measured physical activity in insufficiently active adults. Methods: Using concealed allocation and blinded assessments, eligible participants (n = 40) were randomised to a lower-measurement-frequency (baseline and 18-weeks) or higher-measurement-frequency group (baseline, 6, 12 and 18-weeks). The primary outcome was daily minutes of moderate-to-vigorous physical activity (accelerometry). Secondary outcomes included functional aerobic capacity (STEP tool), quality-of-life (AQoL-6D), body mass index, waist circumference, waist-to-hip ratio and blood pressure. Results: Between-group comparisons were not significant in intention-to-treat analyses. However, there was a trend for the higher-measurement-frequency group to complete more daily minutes of moderate-to-vigorous physical activity at 18-weeks (mean difference 19.6 vs - 11.9 mins/week, p = 0.084), with a medium effect size (Cohen's d = 0.58). This was significant in per-protocol analysis (p = 0.049, Cohen's d = 0.77). Within-group comparisons indicated both groups increased their aerobic fitness (p ≤ 0.01), but only the higher-measurement-frequency group decreased their waist circumference (mean decrease 2.3 cm, 95%CI 0.3-4.3, p = 0.024), diastolic blood pressure (mean decrease 3.4 mmHg, 95%CI 0.03-6.8, p = 0.048) and improved their quality-of-life for independent living (mean increase 3.3, 95%CI 0.2-6.4, p = 0.031). Conclusion: Very brief physical activity interventions by physiotherapists may be an efficient approach to increase physical activity in community-dwelling adults. A larger trial is warranted.

Transformational change in healthcare: an examination of four case studies

Objectives Healthcare leaders around the world are calling for radical, transformational change of our health and care systems. This will be a difficult and complex task. In this article, we examine case studies in which transformational change has been achieved, and seek to learn from these experiences. Methods We used the case study method to investigate examples of transformational change in healthcare. The case studies were identified from preliminary doctoral research into the transition towards future sustainable health and social care systems. Evidence was collected from multiple sources, key features of each case study were displayed in a matrix and thematic analysis was conducted. The results are presented in narrative form. Results Four case studies were selected: two from the US, one from Australia and one from the UK. The notable features are discussed for each case study. There were many common factors: a well communicated vision, innovative redesign, extensive consultation and engagement with staff and patients, performance management, automated information management and high-quality leadership. Conclusions Although there were some notable differences between the case studies, overall the characteristics of success were similar and collectively provide a blueprint for transformational change in healthcare. What is known about the topic? Healthcare leaders around the world are calling for radical redesign of our systems in order to meet the challenges of modern society. What does this paper add? There are some remarkable examples of transformational change in healthcare. The key factors in success are similar across the case studies. What are the implications for practitioners? Collectively, these key factors can guide future attempts at transformational change in healthcare. </jats:p

What is orthopaedic triage? A systematic review

RATIONALE, AIMS AND OBJECTIVES: Complex and chronic disease is placing significant pressure on hospital outpatient departments. Novel ways of delivering care have been developed recently and are often described as ‘triage’ services. This paper reviews the literature pertaining to definitions and descriptions of orthopaedic/musculoskeletal triage processes, in order to provide information on ‘best practice’ to assist health care facilities. METHOD: A comprehensive open-ended search was conducted using electronic databases to identify studies describing models of triage clinics for patients with a musculoskeletal/orthopaedic complaint, who have been referred to hospital outpatient clinics for a surgical consultation. Studies were critically appraised using the McMaster quality appraisal tool and ranked using the National Health and Medical Research Council hierarchy of evidence. A thematic analysis of the definitions, processes and procedures of triage described within the literature was undertaken. RESULTS: 1930 studies were identified and 45 were included in the review (including diagnostic and evaluative research). The hierarchy of evidence ranged from I to IV; however, the majority were at low levels of evidence and scored poorly on the critical appraisal tool. Three broad themes of triage were identified: presence of a referral, configuration of the triage (who, how and where) and the aim of triage. However, there were significant inconsistencies across these themes. CONCLUSIONS: This systematic review highlighted the need for standardization of the definition of triage, the procedures of assessment and management and measures of outcome used in orthopaedic/musculoskeletal triage to ensure best-practice processes, procedures and outcomes for triage clinics

Influence of school community and fitness on prevalence of overweight in Australian school children

AbstractThe study objectives were (1) to determine the variation in prevalence of overweight between school communities, (2) to evaluate the relationship between cardiorespiratory fitness and the probability of being overweight among different school communities, and (3) to test whether this relationship varies between school communities. Using a repeated cross-sectional design, data from 31,424 (15,298 girls, 16,126 boys) Australian school children who had objective assessments of body composition and physical performance were used. Ninety-one schools located across 5 states and territories were included. Independent samples were taken across 12 school years (2000–2011). Analysis used generalised linear mixed models in R with a two-level hierarchical structure—children, nested within school communities. Predictor variables considered were: level 1—gender, age, cardiorespiratory fitness and year of measurement; level 2—school community. A total of 24.6% of the children were overweight and 69% were of low fitness. Variation in the prevalence of overweight between school communities was significant, ranging from 19% to 34%. The probability of being overweight was negatively associated with increasing cardiorespiratory fitness. The relationship was steepest at low fitness and varied markedly between school communities. Children of low fitness had probabilities of being overweight ranging between 26% and 75% depending on school community, whereas those of high fitness had probabilities of <2%. Our findings suggest that most might be gained from a public health perspective by focusing intervention on the least fit children in the worst-performing communities

Site-selective, catalytic, and diastereoselective sp3 C–H hydroxylation and alkoxylation of vicinally functionalized lactams

The C–H bond functionalization of sp3 carbon centres presents a significant challenge due to the inert nature of hydrocarbons as well as the need to selectively functionalize one of the numerous aliphatic C–H bonds embodied in organic molecules. Here, we describe catalytic, diastereoselective, and site-selective sp3 C–H hydroxylation/alkoxylation protocols featuring dihydroisoquinolones, γ-, and δ-lactams, which bear vicinal stereocenters. The hydroxylation strategy utilizes oxygen, a waste-free oxidant and affords attractive fragments for potential drug discovery. Fe-catalyzed dehydrative coupling of the resulting tertiary alcohols with simple primary alcohols has led to the construction of highly versatile unsymmetrical dialkyl ethers

Is Walk Score associated with hospital admissions from chronic diseases? Evidence from a cross-sectional study in a high socioeconomic status Australian city-state

Objectives: To explore patterns of non-communicable diseases (NCDs) in the Australian Capital Territory (ACT).To ascertain the effect of the neighbourhood built environmental features and especially walkability on health outcomes, specifically for hospital admissions from NCDs. Design: A cross-sectional analysis of public hospital episode data (2007–2013). Setting: Hospitalisations from the ACT, Australia at very small geographic areas. Participants: Secondary data on 75 290 unique hospital episodes representing 39 851 patients who were admitted to ACT hospitals from 2007 to 2013. No restrictions on age, sex or ethnicity. Main exposure measures: Geographic Information System derived or compatible measures of general practitioner access, neighbourhood socioeconomic status, alcohol access, exposure to traffic and Walk Score walkability. Main outcome measures: Hospitalisations of circulatory diseases, specific endocrine, nutritional and metabolic diseases, respiratory diseases and specific cancers. Results: Geographic clusters with significant high and low risks of NCDs were found that displayed an overall geographic pattern of high risk in the outlying suburbs of the territory. Significant relationships between neighbourhood walkability as measured by Walk Score and the likelihood of hospitalisation with a primary diagnosis of myocardial infarction (heart attack) were found. A possible relationship was also found with the likelihood of being hospitalised with 4 major lifestylerelated cancers. Conclusions: Our research augments the growing literature underscoring the relationships between the built environment and health outcomes. In addition, it supports the importance of walkable neighbourhoods, as measured by Walk Score, for improved health.Full Tex
