Michele P Hamm; Annabritt Chisholm; Jocelyn Shulhan; Andrea Milne; Shannon D. Scott; Lisa M. Given; Lisa Hartling

Objective To map the state of the existing literature evaluating the use of social media in patient and caregiver populations. Design Scoping review. Data sources Medline, CENTRAL, ERIC, PubMed, CINAHL Plus Full Text, Academic Search Complete, Alt Health Watch, Health Source, Communication and Mass Media Complete, Web of Knowledge and ProQuest (2000–2012). Study selection Studies reporting primary research on the use of social media (collaborative projects, blogs/microblogs, content communities, social networking sites, virtual worlds) by patients or caregivers. Data extraction Two reviewers screened studies for eligibility; one reviewer extracted data from relevant studies and a second performed verification for accuracy and completeness on a 10% sample. Data were analysed to describe which social media tools are being used, by whom, for what purpose and how they are being evaluated. Results Two hundred eighty-four studies were included. Discussion forums were highly prevalent and constitute 66.6% of the sample. Social networking sites (14.8%) and blogs/microblogs (14.1%) were the next most commonly used tools. The intended purpose of the tool was to facilitate self-care in 77.1% of studies. While there were clusters of studies that focused on similar conditions (eg, lifestyle/weight loss (12.7%), cancer (11.3%)), there were no patterns in the objectives or tools used. A large proportion of the studies were descriptive (42.3%); however, there were also 48 (16.9%) randomised controlled trials (RCTs). Among the RCTs, 35.4% reported statistically significant results favouring the social media intervention being evaluated; however, 72.9% presented positive conclusions regarding the use of social media. Conclusions There is an extensive body of literature examining the use of social media in patient and caregiver populations. Much of this work is descriptive; however, with such widespread use, evaluations of effectiveness are required. In studies that have examined effectiveness, positive conclusions are often reported, despite non-significant findings.

OBJECTIVES To assess inter-rater reliability and validity of the Newcastle Ottawa Scale (NOS) used for methodological quality assessment of cohort studies included in systematic reviews. STUDY DESIGN AND SETTING Two reviewers independently applied the NOS to 131 cohort studies included in eight meta-analyses. Inter-rater reliability was calculated using kappa (κ) statistics. To assess validity, within each meta-analysis, we generated a ratio of pooled estimates for each quality domain. Using a random-effects model, the ratios of odds ratios for each meta-analysis were combined to give an overall estimate of differences in effect estimates. RESULTS Inter-rater reliability varied from substantial for length of follow-up (κ = 0.68, 95% confidence interval [CI] = 0.47, 0.89) to poor for selection of the nonexposed cohort and demonstration that the outcome was not present at the outset of the study (κ = -0.03, 95% CI = -0.06, 0.00; κ = -0.06, 95% CI = -0.20, 0.07). Reliability for overall score was fair (κ = 0.29, 95% CI = 0.10, 0.47). In general, reviewers found the tool difficult to use and the decision rules vague even with additional information provided as part of this study. We found no association between individual items or overall score and effect estimates. CONCLUSION Variable agreement and lack of evidence that the NOS can identify studies with biased results underscore the need for revisions and more detailed guidance for systematic reviewers using the NOS.

BACKGROUND Pain management is integral to the management of hip fracture. PURPOSE To review the benefits and harms of pharmacologic and nonpharmacologic interventions for managing pain after hip fracture. DATA SOURCES 25 electronic databases (January 1990 to December 2010), gray literature, trial registries, and reference lists, with no language restrictions. STUDY SELECTION Multiple reviewers independently and in duplicate screened 9357 citations to identify randomized, controlled trials (RCTs); nonrandomized, controlled trials (non-RCTs); and cohort studies of pain management techniques in older adults after acute hip fracture. DATA EXTRACTION Independent, duplicate data extraction and quality assessment were conducted, with discrepancies resolved by consensus or a third reviewer. Data extracted included study characteristics, inclusion and exclusion criteria, participant characteristics, interventions, and outcomes. DATA SYNTHESIS 83 unique studies (64 RCTs, 5 non-RCTs, and 14 cohort studies) were included that addressed nerve blockade (n = 32), spinal anesthesia (n = 30), systemic analgesia (n = 3), traction (n = 11), multimodal pain management (n = 2), neurostimulation (n = 2), rehabilitation (n = 1), and complementary and alternative medicine (n = 2). Overall, moderate evidence suggests that nerve blockades are effective for relieving acute pain and reducing delirium. Low-level evidence suggests that preoperative traction does not reduce acute pain. Evidence was insufficient on the benefits and harms of most interventions, including spinal anesthesia, systemic analgesia, multimodal pain management, acupressure, relaxation therapy, transcutaneous electrical neurostimulation, and physical therapy regimens, in managing acute pain. LIMITATIONS No studies evaluated outcomes of chronic pain or exclusively examined participants from nursing homes or with cognitive impairment. Systemic analgesics (narcotics, nonsteroidal anti-inflammatory drugs) were understudied during the search period. CONCLUSION Nerve blockade seems to be effective in reducing acute pain after hip fracture. Sparse data preclude firm conclusions about the relative benefits or harms of many other pain management interventions for patients with hip fracture.

Objectives To conduct a systematic review of randomised controlled trials (RCTs) examining the use of social media to promote healthy diet and exercise in the general population. Data sources MEDLINE, CENTRAL, ERIC, PubMed, CINAHL, Academic Search Complete, Alt Health Watch, Health Source, Communication and Mass Media Complete, Web of Knowledge and ProQuest Dissertation and Thesis (2000–2013). Study eligibility criteria RCTs of social media interventions promoting healthy diet and exercise behaviours in the general population were eligible. Interventions using social media, alone or as part of a complex intervention, were included. Study appraisal and synthesis Study quality was assessed using the Cochrane Risk of Bias Tool. We describe the studies according to the target populations, objectives and nature of interventions, outcomes examined, and results and conclusions. We extracted data on the primary and secondary outcomes examined in each study. Where the same outcome was assessed in at least three studies, we combined data in a meta-analysis. Results 22 studies were included. Participants were typically middle-aged Caucasian women of mid-to-high socioeconomic status. There were a variety of interventions, comparison groups and outcomes. All studies showed a decrease in programme usage throughout the intervention period. Overall, no significant differences were found for primary outcomes which varied across studies. Meta-analysis showed no significant differences in changes in physical activity (standardised mean difference (SMD) 0.13 (95% CI −0.04 to 0.30), 12 studies) and weight (SMD −0.00 (95% CI −0.19 to 0.19), 10 studies); however, pooled results from five studies showed a significant decrease in dietary fat consumption with social media (SMD −0.35 (95% CI −0.68 to −0.02)). Conclusions Social media may provide certain advantages for public health interventions; however, studies of social media interventions to date relating to healthy lifestyles tend to show low levels of participation and do not show significant differences between groups in key outcomes.

The widespread detection of perfluorinated acids (PFAs) in humans and known developmental toxicity in animals has raised concern about their potential effects on human reproductive health. Our objective was to determine whether increasing maternal exposure to PFAs is associated with adverse effects on fetal growth and length of gestation in women giving birth in Alberta, Canada. We examined the concentrations of perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), and perfluorohexane sulfonate (PFHxS) in a cohort of 252 pregnant women who gave birth to live singletons. Each of the women had undergone an early second trimester prenatal screen, and her serum was analyzed for PFA concentrations. Data on infant and maternal variables were collected from the delivery record completed at birth. Adjusted changes in birth weight per natural log (ng/ml) of PFOA (median 1.5 ng/ml), PFHxS (median 0.97 ng/ml), and PFOS (median 7.8 ng/ml) were −37.4 g (95% confidence interval (CI): −86.0 to 11.2 g), 21.9 g (−23.4 to 67.2 g), and 31.3 g (−43.3 to 105.9 g), respectively. Mean birth weight z-score, standardized for gestational age and gender, length of gestation, and risk of preterm birth did not appear to be influenced by maternal PFA exposure. When PFA concentrations were divided into tertiles, similar patterns were observed. These results suggest that maternal PFA exposure has no substantial effect on fetal weight and length of gestation at the concentrations observed in this population.

Purpose To conduct a scoping review of the literature on social media use by health care professionals and trainees. Method The authors searched MEDLINE, CENTRAL, ERIC, PubMed, CINAHL Plus Full Text, Academic Search Complete, Alt Health Watch, Health Source, Communication and Mass Media Complete, Web of Knowledge, and ProQuest for studies published between 2000 and 2012. They included those reporting primary research on social media use by health care professionals or trainees. Two reviewers screened studies for eligibility; one reviewer extracted data and a second verified a 10% sample. They analyzed data descriptively to determine which social media tools were used, by whom, for what purposes, and how they were evaluated. Results The authors included 96 studies in their review. Discussion forums were the most commonly studied tools (43/96; 44.8%). Researchers more often studied social media in educational than practice settings. Of common specialties, administration, critical appraisal, and research appeared most often (11/96; 11.5%), followed by public health (9/96; 9.4%). The objective of most tools was to facilitate communication (59/96; 61.5%) or improve knowledge (41/96; 42.7%). Thirteen studies evaluated effectiveness (13.5%), and 41 (42.7%) used a cross-sectional design. Conclusions These findings provide a map of the current literature on social media use in health care, identify gaps in that literature, and provide direction for future research. Social media use is widespread, particularly in education settings. The versatility of these tools suggests their suitability for use in a wide range of professional activities. Studies of their effectiveness could inform future practice.

IMPORTANCE Social media has had a profound effect on how children and adolescents interact. While there are many benefits to the use of social media, cyberbullying has emerged as a potential harm, raising questions regarding its influence on mental health. OBJECTIVE To review existing publications that examine the health-related effects of cyberbullying via social media among children and adolescents. EVIDENCE REVIEW We searched 11 electronic databases from January 1, 2000, through January 17, 2012 (updated June 24, 2014). Studies were screened by 2 independent reviewers and were included if they reported primary research, described or evaluated the use of a social media tool in the context of cyberbullying, and were conducted with children or adolescents. Data were extracted by 1 reviewer and verified by a second. All studies were assessed by 2 reviewers for methodological quality using the Mixed Methods Appraisal Tool. Results were not pooled owing to heterogeneity in study objectives and outcomes; a narrative analysis is presented. FINDINGS Thirty-six studies in 34 publications were included. Most were conducted in the United States (21 [58.3%]), sampled middle and high school populations (24 [66.7%]), and included adolescents who were 12 to 18 years of age (35 [97.2%]). The median reported prevalence of cyberbullying was 23.0% (interquartile range, 11.0%-42.6%). Five studies reported inconsistent and/or weak correlations between cyberbullying and anxiety. Ten studies found a statistically significant association between cyberbullying and report of depression. Five studies investigated self-harm or suicidality, with conflicting results. Results indicate that the most common reason for cyberbullying is relationship issues, with girls most often being the recipients. Responses to cyberbullying are most often passive, with a pervasive lack of awareness or confidence that anything can be done. CONCLUSIONS AND RELEVANCE There is a consistent relationship across studies between cyberbullying and depression among children and adolescents; however, the evidence of the effect of cyberbullying on other mental health conditions is inconsistent. This review provides important information that characterizes cyberbullying within the context of social media, including attributes of the recipients and perpetrators, reasons for and the nature of bullying behaviors, and how recipients react to and manage bullying behaviors. This information is critical to the development of effective prevention and management strategies.

A systematic review of the use and effectiveness of social media in child health

Michele P Hamm; Jocelyn Shulhan; Gillian Williams; Andrea Milne; Shannon D. Scott; Lisa Hartling

BackgroundSocial media use is highly prevalent among children, youth, and their caregivers, and its use in healthcare is being explored. The objective of this study was to conduct a systematic review to determine: 1) for what purposes social media is being used in child health and its effectiveness; and 2) the attributes of social media tools that may explain how they are or are not effective.MethodsWe searched Medline, CENTRAL, ERIC, PubMed, CINAHL, Academic Search Complete, Alt Health Watch, Health Source, Communication and Mass Media Complete, Web of Knowledge, and Proquest Dissertation and Theses Database from 2000–2013. We included primary research that evaluated the use of a social media tool, and targeted children, youth, or their families or caregivers. Quality assessment was conducted on all included analytic studies using tools specific to different quantitative designs.ResultsWe identified 25 studies relevant to child health. The majority targeted adolescents (64%), evaluated social media for health promotion (52%), and used discussion forums (68%). Most often, social media was included as a component of a complex intervention (64%). Due to heterogeneity in conditions, tools, and outcomes, results were not pooled across studies. Attributes of social media perceived to be effective included its use as a distraction in younger children, and its ability to facilitate communication between peers among adolescents. While most authors presented positive conclusions about the social media tool being studied (80%), there is little high quality evidence of improved outcomes to support this claim.ConclusionsThis comprehensive review demonstrates that social media is being used for a variety of conditions and purposes in child health. The findings provide a foundation from which clinicians and researchers can build in the future by identifying tools that have been developed, describing how they have been used, and isolating components that have been effective.

STUDY OBJECTIVE We evaluate the effectiveness of interventions for pediatric patients with suicide-related emergency department (ED) visits. METHODS We searched of MEDLINE, EMBASE, the Cochrane Library, other electronic databases, references, and key journals/conference proceedings. We included experimental or quasiexperimental studies that evaluated psychosocial interventions for pediatric suicide-related ED visits. Inclusion screening, study selection, and methodological quality were assessed by 2 independent reviewers. One reviewer extracted the data and a second checked for completeness and accuracy. Consensus was reached by conference; disagreements were adjudicated by a third reviewer. We calculated odds ratios, relative risks (RRs), or mean differences for each studys primary outcome, with 95% confidence intervals (CIs). Meta-analysis was deferred because of clinical heterogeneity in intervention, patient population, and outcome. RESULTS We included 7 randomized controlled trials and 3 quasiexperimental studies, grouping and reviewing them according to intervention delivery: ED-based delivery (n=1), postdischarge delivery (n=6), and ED transition interventions (n=3). An ED-based discharge planning intervention increased the number of attended post-ED treatment sessions (mean difference=2.6 sessions; 95% CI 0.05 to 5.15 sessions). Of the 6 studies of postdischarge delivery interventions, 1 found increased adherence with service referral in patients who received community nurse home visits compared with simple placement referral at discharge (RR=1.28; 95% CI 1.06 to 1.56). The 3 ED transition intervention studies reported (1) reduced risk of subsequent suicide after brief ED intervention and postdischarge contact (RR=0.10; 95% CI 0.03 to 0.41); (2) reduced suicide-related hospitalizations when ED visits were followed up with interim, psychiatric care (RR=0.41; 95% CI 0.28 to 0.60); and (3) increased likelihood of treatment completion when psychiatric evaluation in the ED was followed by attendance of outpatient sessions with a parent (odds ratio=2.78; 95% CI 1.20 to 6.67). CONCLUSION Transition interventions appear most promising for reducing suicide-related outcomes and improving post-ED treatment adherence. Use of similar interventions and outcome measures in future studies would enhance the ability to derive strong recommendations from the clinical evidence in this area.

BackgroundRandomized controlled trials (RCTs) are the gold standard for trials assessing the effects of therapeutic interventions; therefore it is important to understand how they are conducted. Our objectives were to provide an overview of a representative sample of pediatric RCTs published in 2007 and assess the validity of their results.MethodsWe searched Cochrane Central Register of Controlled Trials using a pediatric filter and randomly selected 300 RCTs published in 2007. We extracted data on trial characteristics; outcomes; methodological quality; reporting; and registration and protocol characteristics. Trial registration and protocol availability were determined for each study based on the publication, an Internet search and an author survey.ResultsMost studies (83%) were efficacy trials, 40% evaluated drugs, and 30% were placebo-controlled. Primary outcomes were specified in 41%; 43% reported on adverse events. At least one statistically significant outcome was reported in 77% of trials; 63% favored the treatment group. Trial registration was declared in 12% of publications and 23% were found through an Internet search. Risk of bias (ROB) was high in 59% of trials, unclear in 33%, and low in 8%. Registered trials were more likely to have low ROB than non-registered trials (16% vs. 5%; p = 0.008). Effect sizes tended to be larger for trials at high vs. low ROB (0.28, 95% CI 0.21,0.35 vs. 0.16, 95% CI 0.07,0.25). Among survey respondents (50% response rate), the most common reason for trial registration was a publication requirement and for non-registration, a lack of familiarity with the process.ConclusionsMore than half of this random sample of pediatric RCTs published in 2007 was at high ROB and three quarters of trials were not registered. There is an urgent need to improve the design, conduct, and reporting of child health research.
