RESUMO

BACKGROUND: Social networking platforms offer a wide reach for public health interventions allowing communication with broad audiences using tools that are generally free and straightforward to use and may be combined with other components, such as public health policies. We define interactive social media as activities, practices, or behaviours among communities of people who have gathered online to interactively share information, knowledge, and opinions. OBJECTIVES: We aimed to assess the effectiveness of interactive social media interventions, in which adults are able to communicate directly with each other, on changing health behaviours, body functions, psychological health, well-being, and adverse effects. Our secondary objective was to assess the effects of these interventions on the health of populations who experience health inequity as defined by PROGRESS-Plus. We assessed whether there is evidence about PROGRESS-Plus populations being included in studies and whether results are analysed across any of these characteristics. SEARCH METHODS: We searched CENTRAL, CINAHL, Embase, MEDLINE (including trial registries) and PsycINFO. We used Google, Web of Science, and relevant web sites to identify additional studies and searched reference lists of included studies. We searched for published and unpublished studies from 2001 until June 1, 2020. We did not limit results by language. SELECTION CRITERIA: We included randomised controlled trials (RCTs), controlled before-and-after (CBAs) and interrupted time series studies (ITSs). We included studies in which the intervention website, app, or social media platform described a goal of changing a health behaviour, or included a behaviour change technique. The social media intervention had to be delivered to adults via a commonly-used social media platform or one that mimicked a commonly-used platform. We included studies comparing an interactive social media intervention alone or as a component of a multi-component intervention with either a non-interactive social media control or an active but less-interactive social media comparator (e.g. a moderated versus an unmoderated discussion group). Our main outcomes were health behaviours (e.g. physical activity), body function outcomes (e.g. blood glucose), psychological health outcomes (e.g. depression), well-being, and adverse events. Our secondary outcomes were process outcomes important for behaviour change and included knowledge, attitudes, intention and motivation, perceived susceptibility, self-efficacy, and social support. DATA COLLECTION AND ANALYSIS: We used a pre-tested data extraction form and collected data independently, in duplicate. Because we aimed to assess broad outcomes, we extracted only one outcome per main and secondary outcome categories prioritised by those that were the primary outcome as reported by the study authors, used in a sample size calculation, and patient-important. MAIN RESULTS: We included 88 studies (871,378 participants), of which 84 were RCTs, three were CBAs and one was an ITS. The majority of the studies were conducted in the USA (54%). In total, 86% were conducted in high-income countries and the remaining 14% in upper middle-income countries. The most commonly used social media platform was Facebook (39%) with few studies utilising other platforms such as WeChat, Twitter, WhatsApp, and Google Hangouts. Many studies (48%) used web-based communities or apps that mimic functions of these well-known social media platforms. We compared studies assessing interactive social media interventions with non-interactive social media interventions, which included paper-based or in-person interventions or no intervention. We only reported the RCT results in our 'Summary of findings' table. We found a range of effects on health behaviours, such as breastfeeding, condom use, diet quality, medication adherence, medical screening and testing, physical activity, tobacco use, and vaccination. For example, these interventions may increase physical activity and medical screening tests but there was little to no effect for other health behaviours, such as improved diet or reduced tobacco use (20,139 participants in 54 RCTs). For body function outcomes, interactive social media interventions may result in small but important positive effects, such as a small but important positive effect on weight loss and a small but important reduction in resting heart rate (4521 participants in 30 RCTs). Interactive social media may improve overall well-being (standardised mean difference (SMD) 0.46, 95% confidence interval (CI) 0.14 to 0.79, moderate effect, low-certainty evidence) demonstrated by an increase of 3.77 points on a general well-being scale (from 1.15 to 6.48 points higher) where scores range from 14 to 70 (3792 participants in 16 studies). We found no difference in effect on psychological outcomes (depression and distress) representing a difference of 0.1 points on a standard scale in which scores range from 0 to 63 points (SMD -0.01, 95% CI -0.14 to 0.12, low-certainty evidence, 2070 participants in 12 RCTs). We also compared studies assessing interactive social media interventions with those with an active but less interactive social media control (11 studies). Four RCTs (1523 participants) that reported on physical activity found an improvement demonstrated by an increase of 28 minutes of moderate-to-vigorous physical activity per week (from 10 to 47 minutes more, SMD 0.35, 95% CI 0.12 to 0.59, small effect, very low-certainty evidence). Two studies found little to no difference in well-being for those in the intervention and control groups (SMD 0.02, 95% CI -0.08 to 0.13, small effect, low-certainty evidence), demonstrated by a mean change of 0.4 points on a scale with a range of 0 to 100. Adverse events related to the social media component of the interventions, such as privacy issues, were not reported in any of our included studies. We were unable to conduct planned subgroup analyses related to health equity as only four studies reported relevant data. AUTHORS' CONCLUSIONS: This review combined data for a variety of outcomes and found that social media interventions that aim to increase physical activity may be effective and social media interventions may improve well-being. While we assessed many other outcomes, there were too few studies to compare or, where there were studies, the evidence was uncertain. None of our included studies reported adverse effects related to the social media component of the intervention. Future studies should assess adverse events related to the interactive social media component and should report on population characteristics to increase our understanding of the potential effect of these interventions on reducing health inequities.

RESUMO

Although geared towards a common goal - improved patient-centred care - quality improvement strategies and patient engagement-focused approaches are often developed and conducted in silos. The lack of integration may lead, on the one hand, to the uptake of patient suggestions that do not always take into consideration implications for the delivery of quality care and, on the other hand, to inadequate understanding of patient views required to create optimal services. The Children's Hospital of Eastern Ontario (CHEO)'s action plans to address gaps in patient engagement and quality improvement, two of its priority areas, were initially carried out in isolation of each other. While implementing a key patient engagement initiative using an experience-based co-design approach, Lean process improvement tools were used to plan and implement projects to improve patient, family and staff experiences of care. Preliminary assessments of this project revealed that the integration of these two approaches is feasible and that it was well received by both staff and families. There is important synergy to be found between patient engagement and quality improvement that needs to be leveraged by organizational structures and processes to fulfill the commitments inherent in both fields.

RESUMO

Our study aimed to investigate the impact of various emulsifiers, namely whey protein isolate (WPI), soy protein isolate (SPI), and Tween 80 (Tw), on their ability to encapsulate cannabis oil with maltodextrin as the wall material. The physicochemical properties of the powder, the stability of the cannabinoids, and their bioaccessibility during static in vitro digestion were examined. The average diameter of fat globules in liquid nanoemulsions was 170, 259, and 95 nm for WPI, SPI, and Tw, respectively. The encapsulation efficiency was high for protein emulsifiers (>95%) compared to Tw (∼16%). Upon powder reconstitution in water, the emulsified fat droplets remained stable for WPI (176 nm); however, higher fat globule size (diameters of 346 nm and 210 nm) was observed for SPI and Tw powders, respectively. All oil powders had high solubility (>97%). The peroxide value (PV) showed nearly a fourfold increase for the oil extracted from the powder than the initial PV of bulk oil (5.2 mEq). However, UPLC-TUV analysis of the main cannabinoids (CBD, THC, and CBN) indicated that there is no significant difference between the various formulations and the bulk oil, except for lower Tw. The in vitro digestion model results showed higher bioaccessibility of the cannabinoids for Tw (∼53%) than for proteins (WPI ∼ 7% and SPI ∼ 10%). These findings suggest that the emulsifiers used for spray drying nanoencapsulation of cannabis oil have an impact on the encapsulation efficiency and cannabinoid bioaccessibility, highlighting the importance of choosing adequate emulsifiying agents for their optimal oral delivery.

RESUMO

It describes how the lessons learned from and the approaches to setting priorities for funding health services are translated into setting priorities for funding health services research, in which the paymasters want to use the finite human and financial resources for those areas most likely to improve health services delivery.
