“…The scaled-up evaluation could use any type of comparative design (eg RCT, quasi-RCT). Similar to previous reviews, (13)(14)(15) in order to be considered a "scaleup" the study had to be delivered on a larger scale than the original (prescale) trial, such as with a larger number of participants, and also include at least one outcome (either primary or secondary outcome) in common with the original trial to allow for comparison of effects across the trials. We supplemented this search by searching the intervention website (if available) for additional relevant publications or resources and the reference list of the published trials.…”

“…A 2017 systematic review of public health interventions targeting behavioural risk factors such as smoking, alcohol, nutrition, physical activity, and obesity prevention identified just 40 scaled-up interventions globally. (12) Concerningly, reviews of obesity prevention, (13) nutrition, (14) and physical activity (15) interventions found that scaled-up interventions fail to retain their pre-scale up effect (also known as voltage drop), demonstrating less than half of their original effect. However, none of the previous reviews have included studies targeting children in the first 2 years of life.…”

Child obesity is one of the most significant public health issue globally. Given the high prevalence of overweight and obesity in children, there is a need to identify effective obesity prevention efforts that can be delivered at scale to improve child health. Intervention in infants and young children are critical as this is a period of rapid growth and establishing of lifelong lifestyle behaviours. This rapid review therefore aimed to i) identify obesity prevention interventions targeted at children aged 0-2 that have been scaled-up, and their relative efficacy compared to their prescale trial, ii) describe adaptations made, and the extent to which domains related to scalability have been reported. Of the 14 identified prescale trials, only one formally evaluation of the scale-up trial was identified. For BMI, <10% of the effect was retained, however for nutrition and behavioural outcomes, the proportion of effect retained varied from -11.1% to 144%. Significant adaptations to modality were made in the scaled up trial primarily to reduce cost and increase reach of the intervention. Reporting of scalability domains varied across the 14 trials, with only one trial reporting information for all assessed domains. The findings suggest that there is substantial need for the development and rigorous evaluation of interventions in children aged 0-2 which are designed with scalability in mind.

“…Whilst guidelines have the potential to underpin safe practice and provide safeguards for both patients and clinicians [47], expert and consensus approaches can go beyond high quality evidence, sometimes resulting in inappropriate recommendations [48]. However, evidence-based medicine demands 'the integration of best research evidence with clinical expertise and patient values' [49] while basing recommendations on small-scale or poorly designed trials without the application of expertise and patient values, leading to poor policy [50][51][52][53].…”

Aim Guidelines benefit patients and clinicians by distilling evidence into easy‐to‐read recommendations. The literature around the management of haemorrhoids is immense and guidelines are invaluable to improve treatment integrity and patient outcomes. We identified current haemorrhoid guidelines and assessed them for quality and consistency. Methods A systematic search of the literature from January 2011 to October 2021 was carried out. Guidelines identified were assessed for quality using the AGREE II instrument and for consistency in terms of tabulated treatment recommendations. Results During this period nine guidelines were identified worldwide. The general quality was poor with only one guideline considered of high enough quality for use. In general, expert selection criteria for guideline development groups were vaguely defined. There were inconsistencies in the interpretation of the published evidence leading to variation in treatment recommendations. Discussion Fewer, higher quality guidelines, with more consistent results, are needed. Particular attention should be given to defining the selection of experts involved.

“…However, interventions are expensive [12][13][14], and still commonly reach only a relatively small proportion of individuals [15]. Approaches and attempts to scale up interventions to promote physical activity [16] and healthy eating [17] are encouraging. Despite their success, however, existing approaches seem insufficient given the magnitude of the problem: For example, 27.5% of the world population and 81% of schoolchildren aged 11-17 are not sufficiently physically active [18], and an estimated 2 billion people worldwide are overweight or obese, largely due to an unhealthy diet [19].…”

Background Extensive research has aimed to develop effective interventions for physical inactivity and unhealthy diets, but progress in behavior change techniques (BCTs) has been limited. This study introduces proactive behavior change techniques (ProBCTs) as a novel approach to the problem. By examining techniques people use naturally, without external intervention, the study explores associations, potential causes, and success in behavior change. Methods We translated Abraham & Michie's (2008) 26-BCT taxonomy into a ProBCT questionnaire and administered it to 504 participants via a web survey. Participants reported self-imposed goals in physical activity (PA) and healthy nutrition (NUT), along with their importance, difficulty, and progress. Physical activity and healthy eating questionnaires served as indicators of successful behavior change. Results Using Bayesian statistics, we found variations in the usage intensity of ProBCTs. Similarities and differences emerged between PA and NUT domains. For example, "time management" was commonly used in both, while "information seeking" was more prevalent in NUT. For some ProBCTs, weak evidence emerged for gender differences and age effects. ProBCTs formed clusters similar to BCTs, supported by Bayesian psychometric network analyses. Tests for potential preconditions and consequences of ProBCTs revealed moderate-to-strong support for positive relations with goal importance, and strong support for positive relationships of ProBCTs with behavior change. Moreover, PA was best predicted by a combination of the ProBCTs "time management" plus "detailed plans," whereas for NUT, a complex pattern of six ProBCTs was the best-fitting predictive model. Discussion We discuss the potential of ProBCTs for promoting physical activity and healthy eating add what is still needed to make them work efficiently. Conclusions The ProBCT approach can contribute to the scalability of health behaviour change strategies.
