Assessment of Hypertension Control Among Adults Participating in a Mobile Technology Blood Pressure Self-management Program.

Importance: It is unclear whether mobile technology hypertension self-management programs are associated with blood pressure (BP) control. Objective: To examine whether engagement with a hypertension self-management program with a BP monitor and connected smartphone application with clinically based digital coaching was associated with BP control during a follow-up period of as long as 3 years. Design, Setting, and Participants: This cohort study enrolled US adults with elevated BP or hypertension between January 1, 2015, and July 1, 2020. The hypertension self-management program was provided through the participant's (or their spouse's) employer health plan. Exposures: Program engagement, defined by average number of application sessions. Main Outcomes and Measures: Systolic and diastolic BP measured by a US Food and Drug Administration-cleared BP monitor, with categories defined as normal (systolic BP, <120 mm Hg), elevated (systolic BP, 120-129 mm Hg), stage 1 hypertension (systolic BP, 130-139 mm Hg), and stage 2 hypertension (systolic BP ≥140 mm Hg). Other measures included age, gender, depression, anxiety, diabetes, high cholesterol, smoking, geographic region, area deprivation index, self-reported weight, and device-measured physical activity (steps per day). Results: Among 28 189 participants (median [IQR] age, 51 [43-58] years; 9424 women [40.4%]; 13 902 men [59.6%]), median (IQR) baseline systolic BP was 129.5 mm Hg (120.5-139.6 mm Hg) and diastolic BP was 81.7 mm Hg (75.7-88.4 mm Hg). Median systolic BP at 1 year improved at least 1 category for 495 of 934 participants (53.0%) with baseline elevated BP, 673 of 966 (69.7%) with baseline stage 1 hypertension, and 920 of 1075 (85.7%) with baseline stage 2 hypertension. Participants in the program for 3 years had a mean (SEM) systolic BP reduction of 7.2 (0.4), 12.2 (0.7), and 20.9 (1.7) mm Hg compared with baseline for those starting with elevated, stage 1 hypertension, and stage 2 hypertension, respectively. Greater engagement was associated with lower systolic BP over time (high-engagement group: 131.2 mm Hg; 95% CI, 115.5-155.8 mm Hg; medium-engagement group: 133.4 mm Hg; 95% CI 116.3-159.5 mm Hg; low-engagement group: 135.5 mm Hg; 95% CI, 117.3-164.8 mm Hg; P < .001); these results persisted after adjusting for age, gender, depression, anxiety, diabetes, high cholesterol, smoking, area deprivation index rank, and US region, which was partially mediated by greater physical activity. A very high BP (systolic BP >180 mm Hg) was observed 11 637 times from 3778 participants. Greater engagement was associated with lower risk of very high BP; the estimated probability of a very high BP was greater in the low-engagement group (1.42%; 95% CI, 1.26%-1.59%) compared with the medium-engagement group (0.79%; 95% CI, 0.71%-0.87%; P < .001) and the high-engagement group (0.53%; 95% CI, 0.45%-0.60%; P < .001 for comparison with both groups). Conclusions and Relevance: The findings of this study suggest that a mobile technology hypertension self-management program can support long-term BP control and very high BP detection. Such programs may improve real-world BP monitoring and control.

Does Google Fit provide valid energy expenditure measurements of functional tasks compared to those of Fibion accelerometer in healthy individuals? A cross-sectional study.

BACKGROUND AND AIMS: Smartphone applications (e.g., Google Fit) may be a good alternative tool for accelerometers in estimating energy expenditure of physical activities because they are affordable, easy to use, and freely downloadable on smartphones. We aimed to determine the concurrent validity of the Fibion and Google Fit for measuring energy expenditure of functional tasks in healthy individuals. METHODS: In this cross-sectional study, 28 healthy individuals (21.25 ± 1.84 years) performed certain tasks (lying, standing, 6-min walk test, treadmill walking, stair climbing and cycling) for ∼90 min, while wearing a Fibion accelerometer on their thigh and having the Google Fit application in a smartphone placed in their trouser pocket. Concurrent validity between the energy expenditure data of the Google Fit and Fibion was assessed using the Spearman rho correlation coefficient (data were not normally distributed), Bland-Altman plots and linear regression. RESULTS: Neither energy expenditure for the whole duration nor for the tasks, except sitting + treadmill walking (r = 0.419, p = 0.027), showed significant correlations between the Google Fit and Fibion measurements. A proportional bias was evident for almost all comparisons. CONCLUSIONS: The Google Fit did not provide valid energy expenditure measurements compared to the Fibion for most of the investigated tasks in healthy individuals.

Local- and regional-scale racial and ethnic disparities in air pollution determined by long-term mobile monitoring.

Disparity in air pollution exposure arises from variation at multiple spatial scales: along urban-to-rural gradients, between individual cities within a metropolitan region, within individual neighborhoods, and between city blocks. Here, we improve on existing capabilities to systematically compare urban variation at several scales, from hyperlocal (<100 m) to regional (>10 km), and to assess consequences for outdoor air pollution experienced by residents of different races and ethnicities, by creating a set of uniquely extensive and high-resolution observations of spatially variable pollutants: NO, NO2, black carbon (BC), and ultrafine particles (UFP). We conducted full-coverage monitoring of a wide sample of urban and suburban neighborhoods (93 km2 and 450,000 residents) in four counties of the San Francisco Bay Area using Google Street View cars equipped with the Aclima mobile platform. Comparing scales of variation across the sampled population, greater differences arise from localized pollution gradients for BC and NO (pollutants dominated by primary sources) and from regional gradients for UFP and NO2 (pollutants dominated by secondary contributions). Median concentrations of UFP, NO, and NO2 are, for Hispanic and Black populations, 8 to 30% higher than the population average; for White populations, average exposures to these pollutants are 9 to 14% lower than the population average. Systematic racial/ethnic disparities are influenced by regional concentration gradients due to sharp contrasts in demographic composition among cities and urban districts, while within-group extremes arise from local peaks. Our results illustrate how detailed and extensive fine-scale pollution observations can add new insights about differences and disparities in air pollution exposures at the population scale.

Digital Health Engagement in the US Population: Insights From the 2018 Health Information National Trends Survey.

Objectives. To examine prevalence and predictors of digital health engagement among the US population. Methods. We analyzed nationally representative cross-sectional data on 7 digital health engagement behaviors, as well as demographic and socioeconomic predictors, from the Health Information National Trends Survey (HINTS 5, cycle 2, collected in 2018; n = 2698-3504). We fitted multivariable logistic regression models using weighted survey responses to generate population estimates. Results. Digitally seeking health information (70.14%) was relatively common, whereas using health apps (39.53%) and using a digital device to track health metrics (35.37%) or health goal progress (38.99%) were less common. Digitally communicating with one's health care providers (35.58%) was moderate, whereas sharing health data with providers (17.20%) and sharing health information on social media (14.02%) were uncommon. Being female, younger than 65 years, a college graduate, and a smart device owner positively predicted several digital health engagement behaviors (odds ratio range = 0.09-4.21; P value range < .001-.03). Conclusions. Many public health goals depend on a digitally engaged populace. These data highlight potential barriers to 7 key digital engagement behaviors that could be targeted for intervention.

An App-Based Intervention to Support First Responders and Essential Workers During the COVID-19 Pandemic: Needs Assessment and Mixed Methods Implementation Study.

BACKGROUND: The COVID-19 pandemic has created unprecedented challenges for first responders (eg, police, fire, and emergency medical services) and nonmedical essential workers (eg, workers in food, transportation, and other industries). Health systems may be uniquely suited to support these workers given their medical expertise, and mobile apps can reach local communities despite social distancing requirements. Formal evaluation of real-world mobile app-based interventions is lacking. OBJECTIVE: We aimed to evaluate the adoption, acceptability, and appropriateness of an academic medical center-sponsored app-based intervention (COVID-19 Guide App) designed to support access of first responders and essential workers to COVID-19 information and testing services. We also sought to better understand the COVID-19-related needs of these workers early in the pandemic. METHODS: To understand overall community adoption, views and download data of the COVID-19 Guide App were described. To understand the adoption, appropriateness, and acceptability of the app and the unmet needs of workers, semistructured qualitative interviews were conducted by telephone, by video, and in person with first responders and essential workers in the San Francisco Bay Area who were recruited through purposive, convenience, and snowball sampling. Interview transcripts and field notes were qualitatively analyzed and presented using an implementation outcomes framework. RESULTS: From its launch in April 2020 to September 2020, the app received 8262 views from unique devices and 6640 downloads (80.4% conversion rate, 0.61% adoption rate across the Bay Area). App acceptability was mixed among the 17 first responders interviewed and high among the 10 essential workers interviewed. Select themes included the need for personalized and accurate information, access to testing, and securing personal safety. First responders faced additional challenges related to interprofessional coordination and a "culture of heroism" that could both protect against and exacerbate health vulnerability. CONCLUSIONS: First responders and essential workers both reported challenges related to obtaining accurate information, testing services, and other resources. A mobile app intervention has the potential to combat these challenges through the provision of disease-specific information and access to testing services but may be most effective if delivered as part of a larger ecosystem of support. Differentiated interventions that acknowledge and address the divergent needs between first responders and non-first responder essential workers may optimize acceptance and adoption.

Communication of pain by school-age children with cancer using a game-based symptom assessment app: A secondary analysis.

PURPOSE: To evaluate the self-reported pain experiences of school-age children with cancer participating in a feasibility trial of a game-based symptom assessment app. METHOD: Nineteen children (median: 8 years, range 6-12 years old) receiving cancer treatment were recruited to complete five days of symptom tracking between clinical visits using a symptom assessment app. Children could report pain as a general symptom with the ability to further localize pain on an avatar. Children could also describe symptoms in response to the app's free-text questions or the app's diary. Descriptive statistics characterized reports of pain frequency, severity, bother, and location. Free-text responses were examined for pain-related statements and analyzed using content analysis. RESULTS: All 19 children documented pain on at least one day of app reporting between clinical visits. Pain was most frequently recorded as of mild severity and mild bother. Participants localized pain most frequently to the head, followed by the stomach, chest, extremities, and mouth. Eleven children documented 32 qualitative statements which included rich descriptions of pain-related topics (i.e., "my port hurts a little") and location (i.e., "my vision aching"). CONCLUSIONS: These results demonstrate that school-age children with cancer are willing to describe their ambulatory pain experiences on a game-based mobile app through quantitative reports and by using narrative descriptions. Additionally, these findings can potentially guide clinicians in using multiple approaches to elicit a clinically meaningful evaluation of pain in this population.

Mobility network models of COVID-19 explain inequities and inform reopening.

The coronavirus disease 2019 (COVID-19) pandemic markedly changed human mobility patterns, necessitating epidemiological models that can capture the effects of these changes in mobility on the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)1. Here we introduce a metapopulation susceptible-exposed-infectious-removed (SEIR) model that integrates fine-grained, dynamic mobility networks to simulate the spread of SARS-CoV-2 in ten of the largest US metropolitan areas. Our mobility networks are derived from mobile phone data and map the hourly movements of 98 million people from neighbourhoods (or census block groups) to points of interest such as restaurants and religious establishments, connecting 56,945 census block groups to 552,758 points of interest with 5.4 billion hourly edges. We show that by integrating these networks, a relatively simple SEIR model can accurately fit the real case trajectory, despite substantial changes in the behaviour of the population over time. Our model predicts that a small minority of 'superspreader' points of interest account for a large majority of the infections, and that restricting the maximum occupancy at each point of interest is more effective than uniformly reducing mobility. Our model also correctly predicts higher infection rates among disadvantaged racial and socioeconomic groups2-8 solely as the result of differences in mobility: we find that disadvantaged groups have not been able to reduce their mobility as sharply, and that the points of interest that they visit are more crowded and are therefore associated with higher risk. By capturing who is infected at which locations, our model supports detailed analyses that can inform more-effective and equitable policy responses to COVID-19.

The multi-faceted usage patterns of nutrition apps: a survey on the appropriation of nutrition apps among German-speaking users of MyFitnessPal.

BACKGROUND: Current systematic reviews of randomized controlled trials suggest positive influences of mobile app-based health promotion programs on dietary and physical activity behaviors. However, the actual adoption of and rates of nutrition app use remain low among the overall population. Therefore, we took a step back and investigated actual use patterns. In doing so, we took an appropriation perspective in order to reveal different styles of everyday life integration of these apps. METHODS: We conducted an online survey with 761 German-speaking users of the MyFitnessPal app. Respondents were asked about their detailed use of nutrition apps according to an adapted version of the mobile phone appropriation model. Based on a cluster analysis, different user types were identified. These user types were compared and further described based on analyses of variance. In addition, we conducted a multinomial logistic regression to determine significant predictors of the varying usage patterns. RESULTS: Four different user types were identified: (1) Supported, (2) Indifferent, (3) Health-conscious, and (4) Socializer. These user types mainly differed regarding three aspects: (1) their willingness to adjust default settings to one's own needs and abilities, (2) the role of social support and social norms, and (3) app use for socializing and competition. CONCLUSIONS: Our study sheds light on the multi-faceted appropriation patterns of nutrition apps in Germany, thus paving the way for future studies on mHealth appropriation patterns and the design of more refined mHealth-interventions.

Short-term effect of a smartphone application on the mental health of university students: A pilot study using a user-centered design self-monitoring application for mental health.

BACKGROUND: Despite the widespread recognition of the importance of mental health in young people, only a small proportion of young people with a mental disorder, including university students, receive mental health care. OBJECTIVE: We developed a smartphone application (Mental App) for the university students and examined the effects of the app on their mental health. METHODS: The app was designed according to a questionnaire survey conducted before this study. The Mental App was installed on the students' smartphone and the psychological tests (the Link Stigma Scale, the Center for Epidemiologic Studies Depression Scale, and the 12-item General Health Questionnaire) were performed on the same day. After using the App for two weeks, the students completed a questionnaire survey and underwent the same psychological tests. We compared the results between the app user and non-user group. RESULTS: A total of 68 students participated, of which 57 students completed the study (app user group, n = 28; control group, n = 29). The mean number of days spent using the app was 5.66 ± 3.16 (mean ± SD). The mean total screen time of the app was 9:03 ± 06:41(min:sec). The mean number of total actions (screen taps or swipes) was 161.91 ± 107.34. There were no significant between-group differences in the ΔLink Stigma Scale score (-0.11 ± 4.28 vs. -0.59 ± 3.30, p = 0.496) or the ΔCenter for Epidemiologic Studies Depression Scale score (-4.39 ± 7.13 vs. -2.07 ± 8.78, p = 0.143). There was a significant between-group difference in the ΔGeneral Health Questionnaire score (-2.21± 2.23 vs. -0.17 ± 2.69, p = 0.007). CONCLUSIONS: This non-randomized controlled pilot study indicates that the app we developed, may provide effective mental health care for university students, even in the short-term. Trial registration: UMIN000040332.

Technology usage and barriers to the use of behavioral intervention technologies in adolescents and young adults with spina bifida.

PURPOSE: The majority of behavioral intervention technologies (BITs) have been designed and targeted towards the general population (i.e., typically-developing individuals); thus, little is known about the use of BITs to aid those with special needs, such as youth with disabilities. The current study assessed adolescents and young adults with spina bifida (AYA-SB) for: 1) their technology usage, and 2) anticipated barriers to using technology to help manage their health. METHODS: AYA-SB completed a survey of their media and technology usage. A card sorting task that ranked and grouped anticipated barriers to using a mobile app to manage health was also completed. Ranked means, standard deviations, and the number of times a barrier was discarded were used to interpret sample rankings. RESULTS: AYA-SB reported less frequent technology and media use than the general population. However, differences emerged by age, with young adults endorsing higher usage than their younger counterparts. Top concerns focused on usability, accessibility, safety, personal barriers due to lack of engagement, technological functioning, privacy, and efficacy. CONCLUSIONS: AYA-SB appear to be selective users of technology. It is therefore critical that the design of BITs address their concerns, specifically aiming to have high usability, accessibility, and engagement.

A mobile app to capture EPA assessment data: Utilizing the consolidated framework for implementation research to identify enablers and barriers to engagement.

INTRODUCTION: Mobile apps that utilize the framework of entrustable professional activities (EPAs) to capture and deliver feedback are being implemented. If EPA apps are to be successfully incorporated into programmatic assessment, a better understanding of how they are experienced by the end-users will be necessary. The authors conducted a qualitative study using the Consolidated Framework for Implementation Research (CFIR) to identify enablers and barriers to engagement with an EPA app. METHODS: Structured interviews of faculty and residents were conducted with an interview guide based on the CFIR. Transcripts were independently coded by two study authors using directed content analysis. Differences were resolved via consensus. The study team then organized codes into themes relevant to the domains of the CFIR. RESULTS: Eight faculty and 10 residents chose to participate in the study. Both faculty and residents found the app easy to use and effective in facilitating feedback immediately after the observed patient encounter. Faculty appreciated how the EPA app forced brief, distilled feedback. Both faculty and residents expressed positive attitudes and perceived the app as aligned with the department's philosophy. Barriers to engagement included faculty not understanding the EPA framework and scale, competing clinical demands, residents preferring more detailed feedback and both faculty and residents noting that the app's feedback should be complemented by a tool that generates more systematic, nuanced, and comprehensive feedback. Residents rarely if ever returned to the feedback after initial receipt. DISCUSSION: This study identified key enablers and barriers to engagement with the EPA app. The findings provide guidance for future research and implementation efforts focused on the use of mobile platforms to capture direct observation feedback.

Adaptation and Acceptability of a Digitally Delivered Intervention for Parents of Very Low Birth Weight Infants.

BACKGROUND: Very low birth weight (VLBW) infants are at elevated risk for behavioral problems as early as the second year of life. The purpose of this feasibility study was to evaluate the adaptation and acceptability of an existing digitally delivered behavioral parent training program-the ezParent program, with the addition of weekly coaching calls-for parents of former VLBW infants in their second year of life. OBJECTIVES: To assess the adaptation of ezParent for this population, we assessed parent access and use of ezParent and coaching calls, parent learning of strategies from ezParent, and changes in parenting practices or child behavior after using ezParent plus coaching calls. For acceptability, we assessed if parents viewed ezParent content as applicable to their experiences of parenting a former VLBW infant and how parents viewed coaching calls. METHODS: Ten parents of VLBW infants (20 months of age adjusted for prematurity) were recruited from a neonatal intensive care follow-up clinic. Parents completed the six modules of ezParent plus weekly coaching calls over 10-week intervention period. ezParent usage data were electronically uploaded to secure servers. Completion and timing of coaching calls were monitored using a tracking log. Parents completed child behavior and parenting belief and practice questionnaires pre- and postintervention. Calls were recorded and transcribed to assess for learning of parenting strategies, acceptability with the VLBW population, and acceptability of coaching calls. RESULTS: On average, parents completed 85% of the ezParent modules and 89% of the scheduled coaching calls, respectively. Parents spontaneously introduced 44% of the ezParent strategies during their coaching calls. Modest within-group effect sizes were detected for improvement in parenting self-efficacy and child externalizing behavior. Parents felt the ezParent content applied to their experiences parenting a preterm infant and had high satisfaction with coaching calls as a method of reinforcing program content and assessing knowledge and supporting accountability for program participation. DISCUSSION: ezParent with coaching calls is a feasible method of delivering behavioral parent training to parents of former VLBW infants in their second year of life. Coaching calls have high potential to be a low-cost, time-efficient component of digitally delivered programs that would allow for rapid integration into clinical practice.

The use of WhatsApp group messaging in the coordination of measles supplemental immunization activity in Cross Rivers State, Nigeria, 2018.

INTRODUCTION: Cross Rivers State, in southern Nigeria, conducted measles Supplemental Immunization Activities (SIAs) in 2 phases from 2 -15 March, 2018. The SIAs coordination was led by the State technical coordination committee. A total of 90 supervisors from the national and subnational levels, including consultants were deployed to support the SIAs. The instant messaging service - WhatsApp was utilized to help in the communication and coordination among the State and field teams. METHODS: We reviewed the chat logs from the WhatsApp group exchanges made between 28 February 2018 and 31 March 2018. Thematic content analysis was done. RESULTS: A total of 653 WhatsApp messages were posted among the 55 group members during the study period, including text messages and media content. Eleven percent of the posts related to monitoring processes and data sharing, while posts related to vaccine logistics and waste management made up about 6% of the total. Overall coordination and deployment was covered in 6% of the posts. Forty percent of the media content showed vaccination service delivery and SIAs launching events or monitoring meetings in various areas. The coordination team used WhatsApp to send reminders to the field staff about data sharing, vaccine and waste management, as well as feedback on coverage and completeness of data sharing. The WhatsApp group discussions did not include most of the logistical and hesitancy challenges documented in the State SIAs technical report. CONCLUSION: We recommend focusing group discussions on instant messaging platforms so that they can be used for problem solving and sharing best practices, integrating it with other supervisory processes and tools, as well as providing feedback based on processed data from the field.

Acceptability and usability of a mobile application for management and surveillance of vector-borne diseases in Colombia: An implementation study.

BACKGROUND: Vector-borne diseases are a public health problem in Colombia, where dengue virus infection is hyperendemic. The introduction of other arboviruses, such as chikungunya and Zika in the last three years, has aggravated the situation. Mobile health (mHealth) offers new strategies for strengthening health care and surveillance systems promoting the collection, delivery, and access of health information to professionals, researchers, and patients. Assessing mobile application performance has been a challenge in low- and middle-income countries due to the difficulty of implementing these technologies in different clinical settings. In this study, we evaluate the usability and acceptability of a mobile application, FeverDX, as a support tool in the management of patients with febrile syndrome and suspected arboviruses infection by general practitioners from Colombia. METHODS: A pilot implementation study was conducted to evaluate the usability and acceptability of FeverDX using the modified version of the Mobile Application Rating Scale (uMARS). The evaluation form included 25 questions regarding quantity and quality of information, engagement, functionality, aesthetics, impact, and acceptability by healthcare workers. Each item uses a 5-point scale (1-Inadequate, 2-Poor, 3-Acceptable, 4-Good, 5-Excellent). A global score was obtained for the evaluation form test by determining the median scores of each subsection. A descriptive statistical analysis of the data obtained was performed. RESULTS: Between December 2016 and January 2017, a total of 20 general practitioners from the Emergency room and hospitalization areas evaluated FeverDX. Less than half (9/20) of the evaluators had a comprehensive knowledge of the Colombian Ministry of Health's guidelines for the diagnosis and management of arboviruses, and evaluators partially (4/9) or completely (5/9) agreed that the content of the application follows the management guidelines. On uMARS scale, FeverDX excelled regarding impact (median 5; IQR = 5-5), functionality (median 5; IQR = 4.8-5), and information and scientific basis (median 4; IQR = 4-4). FeverDX scored well regarding user feedback (median 4; IQR = 4-4.5), design and aesthetics (median 4; IQR = 4-4.3), and subjective assessment of quality (median 4.5; IQR = 4.3-4.8). CONCLUSIONS: FeverDX, a mobile application, is a novel mHealth strategy to strengthen care processes and facilitate the detection and reporting of notifiable surveillance diseases. It could improve adherence to clinical practice guidelines for the management and prevention of prevalent diseases as arboviruses in healthcare settings. Although this pilot study used a small sample size, FeverDx performed adequately in a simulated emergency consultation. Further implementation studies are needed to increase the reliability of mHealth technologies in different scenarios.

Assessment of Mobile Health Apps Using Built-In Smartphone Sensors for Diagnosis and Treatment: Systematic Survey of Apps Listed in International Curated Health App Libraries.

BACKGROUND: More than a million health and well-being apps are available from the Apple and Google app stores. Some apps use built-in mobile phone sensors to generate health data. Clinicians and patients can find information regarding safe and effective mobile health (mHealth) apps in third party-curated mHealth app libraries. OBJECTIVE: These independent Web-based repositories guide app selection from trusted lists, but do they offer apps using ubiquitous, low-cost smartphone sensors to improve health? This study aimed to identify the types of built-in mobile phone sensors used in apps listed on curated health app libraries, the range of health conditions these apps address, and the cross-platform availability of the apps. METHODS: This systematic survey reviewed three such repositories (National Health Service Apps Library, AppScript, and MyHealthApps), assessing the availability of apps using built-in mobile phone sensors for the diagnosis or treatment of health conditions. RESULTS: A total of 18 such apps were identified and included in this survey, representing 1.1% (8/699) to 3% (2/76) of all apps offered by the respective libraries examined. About one-third (7/18, 39%) of the identified apps offered cross-platform Apple and Android versions, with a further 50% (9/18) only dedicated to Apple and 11% (2/18) to Android. About one-fourth (4/18, 22%) of the identified apps offered dedicated diagnostic functions, with a majority featuring therapeutic (9/18, 50%) or combined functionality (5/18, 28%). Cameras, touch screens, and microphones were the most frequently used built-in sensors. Health concerns addressed by these apps included respiratory, dermatological, neurological, and anxiety conditions. CONCLUSIONS: Diligent mHealth app library curation, medical device regulation constraints, and cross-platform differences in mobile phone sensor architectures may all contribute to the observed limited availability of mHealth apps using built-in phone sensors in curated mHealth app libraries. However, more efforts are needed to increase the number of such apps on curated lists, as they offer easily accessible low-cost options to assist people in managing clinical conditions.

A Structured E-Investigation Into the Prevalence and Acceptance of Smartphone Applications by Exercise Professionals.

Bromilow, L, Stanton, R, and Humphries, B. A structured e-investigation into the prevalence and acceptance of smartphone applications by exercise professionals. J Strength Cond Res 34(5): 1330-1339, 2020-The primary purpose of this study was to examine the prevalence and acceptance of smartphone applications by exercise professionals when interacting with clients and patients. A 29-item anonymous online survey was designed, containing separate sections on demographics, smartphone proficiency, benefits and barriers to using smartphones, and use of smartphones in a professional setting. Accredited members of the Australian Strength and Conditioning Association, and Exercise and Sports Science Australia received an information sheet through organizational communication channels, inviting them to participate. Two hundred forty-nine exercise professionals completed the survey, with men (71%; n = 176) accounting for most of the respondents. Proficiency using smartphone applications is predominantly-advanced (37%; n = 92), intermediate (33%; n = 82), or expert (14%; n = 35). Identified strategies to find smartphone applications included personal searches (67%; n = 167) and colleague recommendations (55%; n = 137). Reported benefits include fast access to information (67%; n = 167), saves time for record keeping (56%; n = 141), and allows performance tracking (55%; n = 138). Almost all respondents (92%; n = 229) identified barriers, such as inexperience with using particular applications (42%; n = 105). Almost all respondents (96%; n = 239) reported they would recommend smartphone applications to clients and patients, primarily for self-tracking (53%; n = 132). Smartphone use among exercise professionals is prevalent; however, application and sensor technology are reluctantly underused. Increasing acceptance requires embedding within educational curricula, recognition from professional organizations, and collaboration with, to maximize the potential capabilities of smartphone technology within working environments.

Evidence-based medicine self-assessment, knowledge, and integration into daily practice: a survey among Romanian physicians and comparison between trainees and specialists.

BACKGROUND: A gap between the attitude towards evidence-based medicine (EBM), knowledge and awareness has been reported among physicians from different parts of the world. However, no investigation on Romanian physicians is available in the scientific literature. Our study aimed, firstly, to assess EBM awareness and the knowledge used by Romanian physicians, and, secondly, to compare resident trainees with specialists. METHODS: Romanian trainee and specialist physicians were invited to participate in this cross-sectional study. The study tool was an online questionnaire designed to explore their awareness, knowledge, usefulness, the attitude in medical documentation, and the use of professional EBM resources. Data were collected by Google Form from January 1st to April 30th, 2017, respecting the responders' anonymity. Two groups of physicians were investigated as trainees and specialists, respectively. Descriptive statistics (number, percentage, median and interquartile range) was used to describe the survey-related variables. Statistical significance on qualitative data was calculated with the Chi-square test, Fisher's exact test, or the Z-test for proportions. RESULTS: Two hundred and 50 physicians participated in this study (68% trainees vs. 32% specialists). In both groups, a significantly high percentage was represented by women as compared to men (trainees 72.4%, specialists 70%). The correct definition of EBM was identified by most respondents (75.6%). Affirmatively, both trainees and specialists always looked at levels of evidence when reading scientific literature, but a small percentage (6.5% trainees and 3% specialists) adequately identified the uppermost types of evidence in the hierarchy. Almost a quarter of the respondents shared the name of mobile EBM resources that they used to support the daily practice. Only six out of the 49 listed mobile resources met the EBM criteria. CONCLUSIONS: The participants proved to have limited knowledge of EBM and a positive attitude towards the concept. They made use of mobile medical resources without understanding which of these were evidence-based.
