Background Use of social media has become widespread across the United States. Although businesses have invested in social media to engage consumers and promote products, less is known about the extent to which hospitals are using social media to interact with patients and promote health. Objective The aim was to investigate the relationship between hospital social media extent of adoption and utilization relative to hospital characteristics. Methods We conducted a cross-sectional review of hospital-related activity on 4 social media platforms: Facebook, Twitter, Yelp, and Foursquare. All US hospitals were included that reported complete data for the Centers for Medicare and Medicaid Services Hospital Consumer Assessment of Healthcare Providers and Systems survey and the American Hospital Association Annual Survey. We reviewed hospital social media webpages to determine the extent of adoption relative to hospital characteristics, including geographic region, urban designation, bed size, ownership type, and teaching status. Social media utilization was estimated from user activity specific to each social media platform, including number of Facebook likes, Twitter followers, Foursquare check-ins, and Yelp reviews. Results Adoption of social media varied across hospitals with 94.41% (3351/3371) having a Facebook page and 50.82% (1713/3371) having a Twitter account. A majority of hospitals had a Yelp page (99.14%, 3342/3371) and almost all hospitals had check-ins on Foursquare (99.41%, 3351/3371). Large, urban, private nonprofit, and teaching hospitals were more likely to have higher utilization of these accounts. Conclusions Although most hospitals adopted at least one social media platform, utilization of social media varied according to several hospital characteristics. This preliminary investigation of social media adoption and utilization among US hospitals provides the framework for future studies investigating the effect of social media on patient outcomes, including links between social media use and the quality of hospital care and services.

Out-of-hospital cardiac arrest is a major public health problem that affects an estimated 300 000 people in the United States every year.1,2 The application of an automated external defibrillator (AED) to patients who have experienced cardiac arrest has saved many lives. AEDs coupled with cardiopulmonary resuscitation can significantly improve survival from cardiac arrest from 50%.3–5 AEDs can be used easily by untrained laypeople. When accessed and opened, most devices provide audible and visual instructions on use and how to perform cardiopulmonary resuscitation. However, AED effectiveness is extremely time dependent, and presently, in a crisis no comprehensive map of these devices exists to help bystanders find and use them.3,6–9 Previous work from a large database of out-of-hospital cardiac arrest in the United States suggests low (4%, 1166 of 31 689) use of AEDs by bystanders.10 An accurate, easily accessible map of AEDs could help people locate them in an emergency, either directly through smart phone applications (apps) or through communication with map-equipped 911 emergency responders.11 Creating such a map is challenging, and currently, there is no publicly accessible, accurate, comprehensive crowdsourced map for any region in the world. Although sending out an army of staff might allow canvassing of a geographic region, such an approach would be expensive and not clearly scalable. Furthermore, because AEDs can move locations and require maintenance, ensuring that a database of devices had valid, routinely updated data would be a difficult task. Crowdsourcing is increasingly used to address major creative and data gathering challenges.12–15 Crowdsourcing involves taking a task conventionally assigned to particular individuals and instead soliciting help for the task from a large group of diverse individuals (ie, the crowd). The task is often posted online to …

Importance There are few data on the prevalence or outcome of bystander cardiopulmonary resuscitation (BCPR) in children 18 years and younger. Objective To characterize BCPR in pediatric out-of-hospital cardiac arrests (OHCAs). Design, Setting, and Participants This analysis of the Cardiac Arrest Registry to Enhance Survival database investigated nontraumatic OHCAs in children 18 years and younger from January 2013 through December 2015. Exposures Bystander CPR, which included conventional CPR and compression-only CPR. Main Outcomes and Measures Overall survival and neurologically favorable survival, defined as a Cerebral Performance Category score of 1 or 2, at the time of hospital discharge. Results Of the 3900 children younger than 18 years with OHCA, 2317 (59.4%) were infants, 2346 (60.2%) were female, and 3595 (92.2%) had nonshockable rhythms. Bystander CPR was performed on 1814 children (46.5%) and was more common for white children (687 of 1221 [56.3%]) compared with African American children (447 of 1134 [39.4%]) and Hispanic children (197 of 455 [43.3%]) (P < .001). Overall survival and neurologically favorable survival were 11.3% (440 of 3900) and 9.1% (354 of 3900), respectively. On multivariable analysis, BCPR was independently associated with improved overall survival (adjusted proportion, 13.2%; 95% CI, 11.81-14.58; adjusted odds ratio, 1.57; 95% CI, 1.25-1.96) and neurologically favorable survival (adjusted proportion, 10.3%; 95% CI, 9.10-11.54; adjusted odds ratio, 1.50; 95% CI, 1.21-1.98) compared with no BCPR (overall survival: adjusted proportion, 9.5%; 95% CI, 8.28-10.69; neurologically favorable survival: adjusted proportion, 7.59%; 95% CI, 6.50-8.68). For those with data on type of BCPR, 697 of 1411 (49.4%) received conventional CPR and 714 of 1411 (50.6%) received compression-only CPR. On multivariable analysis, only conventional CPR (adjusted proportion, 12.89%; 95% CI, 10.69-15.09; adjusted odds ratio, 2.06; 95% CI, 1.51-2.79) was associated with improved neurologically favorable survival compared with no BCPR (adjusted proportion, 9.59%; 95% CI, 6.45-8.61). There was a significant interaction of BCPR with age. Among infants, conventional BCPR was associated with improved overall survival and neurologically favorable survival while compression-only CPR had similar outcomes to no BCPR. Conclusions and Relevance Bystander CPR is associated with improved outcomes in pediatric OHCAs. Improving the provision of BCPR in minority communities and increasing the use of conventional BCPR may improve outcomes for children with OHCA.

OBJECTIVES Automated external defibrillators (AEDs) are lifesaving, but little is known about where they are located or how to find them. We sought to locate AEDs in high employment areas of Philadelphia and characterize the process of door-to-door surveying to identify these devices. METHODS Block groups representing approximately the top 3rd of total primary jobs in Philadelphia were identified using the US Census Local Employment Dynamics database. All buildings within these block groups were surveyed during regular working hours over six weeks during July-August 2011. Buildings were characterized as publically accessible or inaccessible. For accessible buildings, address, location type, and AED presence were collected. Total devices, location description and prior use were gathered in locations with AEDs. Process information (total people contacted, survey duration) was collected for all buildings. RESULTS Of 1420 buildings in 17 block groups, 949 (67%) were accessible, but most 834 (88%) did not have an AED. 283 AEDs were reported in 115 buildings (12%). 81 (29%) were validated through visualization and 68 (24%) through photo because employees often refused access. In buildings with AEDs, several employees (median 2; range 1-8) were contacted to ascertain information, which required several minutes (mean 4; range 1-55). CONCLUSIONS Door-to-door surveying is a feasible, but time-consuming method for identifying AEDs in high employment areas. Few buildings reported having AEDs and few permitted visualization, which raises concerns about AED access. To improve cardiac arrest outcomes, efforts are needed to improve the availability of AEDs, awareness of their location and access to them.

OBJECTIVES We sought to explore the feasibility of using a crowdsourcing study to promote awareness about automated external defibrillators (AEDs) and their locations. METHODS The Defibrillator Design Challenge was an online initiative that asked the public to create educational designs that would enhance AED visibility, which took place over 8 weeks, from February 6, 2014, to April 6, 2014. Participants were encouraged to vote for AED designs and share designs on social media for points. Using a mixed-methods study design, we measured participant demographics and motivations, design characteristics, dissemination, and Web site engagement. RESULTS Over 8 weeks, there were 13 992 unique Web site visitors; 119 submitted designs and 2140 voted. The designs were shared 48 254 times on Facebook and Twitter. Most designers-voters reported that they participated to contribute to an important cause (44%) rather than to win money (0.8%). Design themes included: empowerment, location awareness, objects (e.g., wings, lightning, batteries, lifebuoys), and others. CONCLUSIONS The Defibrillator Design Challenge engaged a broad audience to generate AED designs and foster awareness. This project provides a framework for using design and contest architecture to promote health messages.

BACKGROUND Social media provide new channels for hospitals to engage with communities, a goal of increasing importance as non-profit hospitals face stricter definitions of community benefit under the Affordable Care Act. We describe the variability in social media presence among US childrens hospitals and the distribution of their Facebook content curation. METHODS Social media data from freestanding childrens hospitals were extracted from September-November 2013. Social media adoption was reviewed for each hospital-generated Facebook, Twitter, YouTube, Google+ and Pinterest platform. Facebook page (number of Likes) and Twitter account (number of followers) engagement were examined by hospital characteristics. Facebook posts from each hospital over a 6-week period were thematically characterized. RESULTS We reviewed 5 social media platforms attributed to 45 childrens hospitals and 2004 associated Facebook posts. All hospitals maintained Facebook and Twitter accounts and most used YouTube (82%), Google+ (53%) and Pinterest (69%). Larger hospitals were more often high performers for Facebook (67% versus 10%, p<0.01) and Twitter (75% versus 17%, p<0.05) engagement than small hospitals. The most common Facebook post-themes were hospital promotion 35% (706), education and information 35% (694), community partnership or benefit 24% (474), fundraising 21% (426), and narratives 12% (241). Of health education posts, 73% (509) provided pediatric health supervision and anticipatory guidance. CONCLUSIONS Social media adoption by US childrens hospitals was widespread. IMPLICATIONS Beyond its traditional marketing role, social media can serve as a conduit for health education, engagement with communities, including community benefit.

BACKGROUND Survival from out-of-hospital cardiac arrest (OHCA) is generally poor and varies by geography. Variability in automated external defibrillator (AED) locations may be a contributing factor. To inform optimal placement of AEDs, we investigated AED access in a major US city relative to demographic and employment characteristics. METHODS AND RESULTS This was a retrospective analysis of a Philadelphia AED registry (2,559 total AEDs). The 2010 US Census and the Local Employment Dynamics database by ZIP code was used. Automated external defibrillator access was calculated as the weighted areal percentage of each ZIP code covered by a 400-m radius around each AED. Of 47 ZIP codes, only 9% (4) were high-AED-service areas. In 26% (12) of ZIP codes, less than 35% of the area was covered by AED service areas. Higher-AED-access ZIP codes were more likely to have a moderately populated residential area (P = .032), higher median household income (P = .006), and higher paying jobs (P =. 008). CONCLUSIONS The locations of AEDs vary across specific ZIP codes; select residential and employment characteristics explain some variation. Further work on evaluating OHCA locations, AED use and availability, and OHCA outcomes could inform AED placement policies. Optimizing the placement of AEDs through this work may help to increase survival.

Background Social media and mobile applications that allow people to work anywhere are changing the way people can contribute and collaborate. Objective We sought to determine the feasibility of using mobile workforce technology to validate the locations of automated external defibrillators (AEDs), an emergency public health resource. Methods We piloted the use of a mobile workforce application, to verify the location of 40 AEDs in Philadelphia county. AEDs were pre-identified in public locations for baseline data. The task of locating AEDs was posted online for a mobile workforce from October 2011 to January 2012. Participants were required to submit a mobile phone photo of AEDs and descriptions of the location. Results Thirty-five of the 40 AEDs were identified within the study period. Most, 91% (32/35) of the submitted AED photo information was confirmed project baseline data. Participants also provided additional data such as business hours and other nearby AEDs. Conclusions It is feasible to engage a mobile workforce to complete health research-related tasks. Participants were able to validate information about emergency public health resources.

OBJECTIVES We described the risk for maltreatment among toddlers of US Army soldiers over different deployment cycles to develop a systematic response within the US Army to provide families appropriate supports. METHODS We conducted a person-time analysis of substantiated maltreatment reports and medical diagnoses among children of 112,325 deployed US Army soldiers between 2001 and 2007. RESULTS Risk of maltreatment was elevated after deployment for children of soldiers deployed once but not for children of soldiers deployed twice. During the 6 months after deployment, children of soldiers deployed once had 4.43 substantiated maltreatment reports and 4.96 medical diagnoses per 10,000 child-months. The highest maltreatment rate among children of soldiers deployed twice occurred during the second deployment for substantiated maltreatment (4.83 episodes per 10,000 child-months) and before the first deployment for medical diagnoses of maltreatment (3.78 episodes per 10,000 child-months). CONCLUSIONS We confirmed an elevated risk for child maltreatment during deployment but also found a previously unidentified high-risk period during the 6 months following deployment, indicating elevated stress within families of deployed and returning soldiers. These findings can inform efforts by the military to initiate and standardize support and preparation to families during periods of elevated risk.

ABSTRACT Objective: To assess the feasibility of a mobile health, inhaled corticosteroid (ICS) adherence reminder intervention and to characterize adherence trajectories immediately following severe asthma exacerbation in high-risk urban children with persistent asthma. Methods: Children aged 2–13 with persistent asthma were enrolled in this pilot randomized controlled trial during an asthma emergency department (ED) visit or hospitalization. Intervention arm participants received daily text message reminders for 30 days, and both arms received electronic sensors to measure ICS use. Primary outcomes were feasibility of sensor use and text message acceptability. Secondary outcomes included adherence to prescribed ICS regimen and 30-day adherence trajectories. Group-based trajectory modeling was used to examine adherence trajectories. Results: Forty-one participants (mean age 5.9) were randomized to intervention (n = 21) or control (n = 20). Overall, 85% were Black, 88% had public insurance, and 51% of the caregivers had a high school education or less. Thirty-two participant families (78%) transmitted medication adherence data; of caregivers who completed the acceptability survey, 25 (96%) chose to receive daily reminders beyond that study interval. Secondary outcome analyses demonstrated similar average daily adherence between groups (intervention = 36%; control = 32%, P = 0.73). Three adherence trajectories were identified with none ever exceeding 80% adherence. Conclusions: Within a high-risk pediatric cohort, electronic monitoring of ICS use and adherence reminders delivered via text message were feasible for most participants, but there was no signal of effect. Adherence trajectories following severe exacerbation were suboptimal, demonstrating an important opportunity for asthma care improvement.
