Use of mobile phones as a tool for weight loss: a systematic review

We conducted a systematic review of the literature on the use of mobile phones for weight loss. A total of 43 studies were identified on obese or overweight adults, aged 18 years or over. After review, ten articles met the inclusion criteria. There were 19–534 participants per study. Participants were from European, Asian and North American regions. The mean body mass index (BMI) of the subjects varied from 22 to 36 kg/m2. Two studies used text messaging or multimedia messaging. All the other studies used mobile-phone apps or web-based programmes that could be accessed from mobile phones as a part of a weight-loss intervention or for evaluating their potential for use and their acceptance. Most studies lasted 2–4 months and the maximum duration was 1 year. All but two studies showed reductions in the participants’ bodyweight, BMI, waist circumference and body fat in the various interventions. There appeared to be a proportional relationship between weight loss and programme use. The programmes most benefited those who took a pro-active approach to everyday problems. Frequent self-recording of weight seemed to be important, as was the personalisation of the intervention (counselling and individualized feedback). Finally, a social support system acted as a motivational tool.

The co-learning process in healthcare professionals

The VCoP users effectiveness does not influence on satisfaction.The VCoP users efficiency to be positively influences on satisfaction.The degree of individual participation in the community influence on satisfaction.This tool can make decisions to improve the success and results of the VCoP. Communities of practice are nowadays an important concept in the healthcare sector. Particularly, the intensive use of ICT has allowed their creation into a virtual environment - Virtual Communities of Practice (VCoPs) developing optimal conditions to make possible the collaborative learning process. The VCoPs antecedents can be situated on social network phenomenon, where individuals with different traits but a common interest/objective are linked, use ICT potency (especially social media) to interchange information, experiences and contents among them. And as a result, people create and share knowledge, and learn collaboratively. VCoP users have a higher satisfaction level in the collaborative learning process when they can: (1) Achieve benefits related to patient diagnosis and treatment (cost reductions, faster management, quality and accuracy of diagnosis, etc.); (2) Increase the share capital of participants and creating networks of trusted individuals. Given the interest in this topic, the objective of this work is to identify the factors that determine user satisfaction in relation to Community Practice (CoP) and the process of building shared knowledge. For this, a sample of 130 Spanish health professionals participating in an online community, and developed in a virtual community of practice, is discussed. The results obtained from an analysis of logistic regression show evidence of the perception of efficiency and effectiveness in collaboration with the members of the VCoP as positively influencing the perceived satisfaction with the CoP. Also, the degree of individual participation in the community affects the degree of perceived satisfaction. The conclusions provide interesting strategic recommendations in the management process of the CoP.

Modelling and predicting eHealth usage in Europe: A multidimensional approach from an online survey of 13,000 European Union Internet users

Background More advanced methods and models are needed to evaluate the participation of patients and citizens in the shared health care model that eHealth proposes. Objective The goal of our study was to design and evaluate a predictive multidimensional model of eHealth usage. Methods We used 2011 survey data from a sample of 13,000 European citizens aged 16–74 years who had used the Internet in the previous 3 months. We proposed and tested an eHealth usage composite indicator through 2-stage structural equation modelling with latent variables and measurement errors. Logistic regression (odds ratios, ORs) to model the predictors of eHealth usage was calculated using health status and sociodemographic independent variables. Results The dimensions with more explanatory power of eHealth usage were health Internet attitudes, information health Internet usage, empowerment of health Internet users, and the usefulness of health Internet usage. Some 52.39% (6811/13,000) of European Internet users’ eHealth usage was more intensive (greater than the mean). Users with long-term health problems or illnesses (OR 1.20, 95% CI 1.12–1.29) or receiving long-term treatment (OR 1.11, 95% CI 1.03–1.20), having family members with long-term health problems or illnesses (OR 1.44, 95% CI 1.34–1.55), or undertaking care activities for other people (OR 1.58, 95% CI 1.40–1.77) had a high propensity toward intensive eHealth usage. Sociodemographic predictors showed that Internet users who were female (OR 1.23, 95% CI 1.14–1.31), aged 25–54 years (OR 1.12, 95% CI 1.05–1.21), living in larger households (3 members: OR 1.25, 95% CI 1.15–1.36; 5 members: OR 1.13, 95% CI 0.97–1.28; ≥6 members: OR 1.31, 95% CI 1.10–1.57), had more children <16 years of age (1 child: OR 1.29, 95% CI 1.18–1.14; 2 children: OR 1.05, 95% CI 0.94–1.17; 4 children: OR 1.35, 95% CI 0.88–2.08), and had more family members >65 years of age (1 member: OR 1.33, 95% CI 1.18–1.50; ≥4 members: OR 1.82, 95% CI 0.54–6.03) had a greater propensity toward intensive eHealth usage. Likewise, users residing in densely populated areas, such as cities and large towns (OR 1.17, 95% CI 1.09–1.25), also had a greater propensity toward intensive eHealth usage. Educational levels presented an inverted U shape in relation to intensive eHealth usage, with greater propensities among those with a secondary education (OR 1.08, 95% CI 1.01–1.16). Finally, occupational categories and net monthly income data suggest a higher propensity among the employed or self-employed (OR 1.07, 95% CI 0.99–1.15) and among the minimum wage stratum, earning ≤€1000 per month (OR 1.66, 95% CI 1.48–1.87). Conclusions We provide new evidence of inequalities that explain intensive eHealth usage. The results highlight the need to develop more specific eHealth practices to address different realities.

Posibilidades de las aplicaciones móviles para el abordaje de la obesidad según los profesionales

INTRODUCTION Given the increasing use and importance of mobile telephone applications (apps) in the health setting, this study aimed to ascertain the views of health professionals involved in the treatment of obesity about their current needs and gaps in their requirements, their willingness to use mobile apps, and the features these devices should have for the treatment of obesity. METHODS A qualitative study was conducted through semi-structured interviews with experts treating obesity. RESULTS The experts believed that apps could be useful to interact or deal with patients. However, their willingness to use apps contrasts with the current limited use of these devices. Practitioners felt that apps could partly compensate for the lack of daily contact between patients and professionals and could increase interaction with patients, achieving more favourable weight control results, especially with regard to improved adherence and motivation. In terms of the functionality and requirements of such apps, the main elements to be included were records of weight, physical activity and food consumption. CONCLUSIONS Adding apps to the existing treatment of overweight and obesity still requires further definition of its functions. Additionally, further investigation is needed into both the role and involvement of professionals in the design process and during treatment.

Keys to success of a community of clinical practice in primary care: a qualitative evaluation of the ECOPIH project

BackgroundThe current reality of primary care (PC) makes it essential to have telemedicine systems available to facilitate communication between care levels. Communities of practice have great potential in terms of care and education, and that is why the Online Communication Tool between Primary and Hospital Care was created. This tool enables PC and non-GP specialist care (SC) professionals to raise clinical cases for consultation and to share information. The objective of this article is to explore healthcare professionals’ views on communities of clinical practice (CoCPs) and the changes that need to be made in an uncontrolled real-life setting after more than two years of use.MethodsA descriptive-interpretative qualitative study was conducted on a total of 29 healthcare professionals who were users and non-users of a CoCP using 2 focus groups, 3 triangular groups and 5 individual interviews. There were 18 women, 21 physicians and 8 nurses. Of the interviewees, 21 were PC professionals, 24 were users of a CoCP and 7 held managerial positions.ResultsFor a system of communication between PC and SC to become a tool that is habitually used and very useful, the interviewees considered that it would have to be able to find quick, effective solutions to the queries raised, based on up-to-date information that is directly applicable to daily clinical practice. Contact should be virtual – and probably collaborative – via a platform integrated into their habitual workstations and led by PC professionals. Organisational changes should be implemented to enable users to have more time in their working day to spend on the tool, and professionals should have a proactive attitude in order to make the most if its potential. It is also important to make certain technological changes, basically aimed at improving the tool’s accessibility, by integrating it into habitual clinical workstations.ConclusionsThe collaborative tool that provides reliable, up-to-date information that is highly transferrable to clinical practice is valued for its effectiveness, efficiency and educational capacity. In order to make the most of its potential in terms of care and education, organisational changes and techniques are required to foster greater use.

Availability of information in Public Health on the Internet: An analysis of national health authorities in the Spanish-speaking Latin American and Caribbean countries

INTRODUCTION Access to reliable and quality health information and appropriate medical advice can contribute to a dramatic reduction in the mortality figures of countries. The governments of the Americas are faced with the opportunity to continue working on this challenge, and their institutional presence on their websites should play a key role in this task. In a setting where the access to information is essential to both health professionals and citizens, it is relevant to analyze the role of national health authorities. Given that search engines play such a key role in the access to health information, it is important to specifically know - in connection to national health authorities - whether health information offered is easily available to the population, and whether this information is well-ranked in search engines. METHODS Quantitative methods were used to gather data on the institutional presence of national health authorities on the web. An exploratory and descriptive research served to analyze and interpret data and information obtained quantitatively from different perspectives, including an analysis by country, and also by leading causes of death. A total of 18 web pages were analyzed. Information on leading causes of death was searched on websites of national health authorities in the week of August 10-14, 2015. RESULTS The probability of finding information of national health authorities on the 10 leading causes of death in a country, among the top 10 results on Google, is 6.66%. Additionally, ten out the 18 countries under study (55%) do not have information ranked among the top results in Google when searching for the selected terms. Additionally, a total of 33 websites represent the sources of information with the highest visibility for all the search strategies in each country on Google for the ten leading causes of death in a country. Two websites, the National Library of Medicine and Wikipedia, occur as a result with visibility in the total of eighteen countries of the sample. CONCLUSIONS Taking into consideration that providing reliable and quality information on these topics to the population should be one of the priorities of national health authorities, these results suggest that national health authorities need to take measures to try to better position their contents.

Understanding the discriminant factors that influence the adoption and use of clinical communities of practice: the ECOPIH case

BackgroundThe aim of the study presented in this article is to analyse the discriminant factors that have an influence on the use of communities of practice by primary and specialist healthcare professionals (physicians and nurses) for information sharing. Obtaining evidence from an ex-ante analysis to determine what factors explain healthcare professionals’ clinical community of practice use allows aspects of its use to be identified.MethodsA theoretical model based on a modified technology acceptance model was used as the analysis tool, and a discriminant analysis was performed. An ad-hoc questionnaire was designed and sent to a study population of 357 professionals from the Badalona-Sant Adrià de Besòs Primary Care Service in Catalonia, Spain, which includes nine primary care centres and three specialist care centres. The study sample was formed by the 166 healthcare professionals who responded.ResultsThe results revealed three main drivers for engagement in a CoP: First, for the whole sample, perceived usefulness for reducing costs associated with clinical practice was the factor with the greatest discriminant power that distinguished between users and non-users, followed by perceived usefulness for improving clinical practice quality, and lastly habitual social media website and application use. Turning to the two sub-samples of healthcare professions (physicians and nurses, respectively), we saw that the usefulness stemming from community of practice use changed. There were differences in the levels of motivation of healthcare professionals with regards to their engagement with CoP. While perceived usefulness for reducing costs associated with clinical practice was the main factor for the physicians, perceived usefulness of the Web 2.0 platform use for communication for improving clinical practice quality and perceived ease of use were the main factors for the nurses.ConclusionsIn the context of communities of practice, the perception of usefulness of Web 2.0 platform use for communication is determined by organisational, technological and social factors. Specifically, the position that professionals have within the healthcare structure and particularly the closer healthcare professionals’ activity is to patients and their professional experience of using social networks and ICTs are crucial to explaining the use of such platforms. Public policies promoting Web 2.0 platform use for communication should therefore go beyond the purely technological dimension and consider other professional and social determinants.

Modeling and Predicting Outcomes of eHealth Usage by European Physicians: Multidimensional Approach from a Survey of 9196 General Practitioners

Background The literature has noted the need to use more advanced methods and models to evaluate physicians’ outcomes in the shared health care model that electronic health (eHealth) proposes. Objective The goal of our study was to design and evaluate a predictive multidimensional model of the outcomes of eHealth usage by European physicians. Methods We used 2012-2013 survey data from a sample of 9196 European physicians (general practitioners). We proposed and tested two composite indicators of eHealth usage outcomes (internal practices and practices with patients) through 2-stage structural equation modeling. Logistic regression (odds ratios, ORs) to model the predictors of eHealth usage outcomes indicators were also calculated. Results European general practitioners who were female (internal practices OR 1.15, 95% CI 1.10-1.20; practices with patients OR 1.19, 95% CI 1.14-1.24) and younger—aged <35 years (internal practices OR 1.14, 95% CI 1.02-1.26; practices with patients OR 1.32, 95% CI 1.13-1.54) and aged 36-45 years (internal practices OR 1.16, 95% CI 1.06-1.28; practices with patients OR 1.21, 95% CI 1.10-1.33)—had a greater propensity toward favorable eHealth usage outcomes in internal practices and practices with patients. European general practitioners who positively valued information and communication technology (ICT) impact on their personal working processes (internal practices OR 5.30, 95% CI 4.73-5.93; practices with patients OR 4.83, 95% CI 4.32-5.40), teamwork processes (internal practices OR 4.19, 95% CI 3.78-4.65; practices with patients OR 3.38, 95% CI 3.05-3.74), and the doctor-patient relationship (internal practices OR 3.97, 95% CI 3.60-4.37; practices with patients OR 6.02, 95% CI 5.43-6.67) had a high propensity toward favorable effects of eHealth usage on internal practices and practices with patients. More favorable eHealth outcomes were also observed for self-employed European general practitioners (internal practices OR 1.33, 95% CI 1.22-1.45; practices with patients OR 1.10, 95% CI 1.03-1.28). Finally, general practitioners who reported that the number of patients treated in the last 2 years had remained constant (internal practices OR 1.08, 95% CI 1.01-1.17) or increased (practices with patients OR 1.12, 95% CI 1.03-1.22) had a higher propensity toward favorable eHealth usage outcomes. Conclusions We provide new evidence of predictors (sociodemographic issues, attitudes toward ICT impacts, and working conditions) that explain favorable eHealth usage outcomes. The results highlight the need to develop more specific policies for eHealth usage to address different realities.

Digital health in the Americas: advances and challenges in connected health

In 2005, all WHO Member States pledged to fight for universal health coverage (UHC). The availability of financial, human and technological resources seems to be necessary to develop efficient health policies and also to offer UHC. One of the main challenges facing the health sector comes from the need to innovate efficiently. The intense use of information and communication technologies (ICTs) in the health field evidences a notable improvement in results obtained by institutions, health professionals and patients, principally in developed countries. In the Americas, the relationship between economic development and health innovation is not particularly evident. Data from 19 of 35 countries surveyed in the 2015 Third Global Survey on eHealth for the region of the Americas were analysed. 52.6% of the countries of the Americas have a national policy or strategy for UHC. 57.9% of the countries in the sample indicate that they have a national eHealth policy or strategy, but only 26.3% have an entity that supervises the quality, safety and reliability regulations for mobile health applications. The survey data indicate that high-income and low-income to middle-income countries show higher percentages in relation to the existence of entities that promote innovation. These countries also exceed 60%—compared with 40% and 50% in lower-income countries—in all cases regarding the use of eHealth practices, such as mobile health, remote patient monitoring or telehealth. 100% of low-income countries report offering ICT training to healthcare professionals, compared with 83% of wealthy countries and 81% of middle-income to high-income countries.

Natural User Interfaces Is It a Solution to Accomplish Ubiquitous Training in Minimally Invasive Surgery

Dear Editor: Graphical user interfaces have evolved to become a standard in the interaction between man and computer. Touch screens have become popular but they require physical contact. Natural user interfaces (NUIs) or gesture-based user interfaces are designed to use human behavior to interact with computers. One behavior can be hand gestures. NUIs allow one to manage without the use of mechanical devices and physical contact with devices such as mouse and keyboards; this characteristic has remarkable importance in medical environments such as operating and autopsy rooms. The methods used for gestures acquisition can be divided in those that include a specific device that the user can physically hold or annex to the body and those that are hands-free/body-free, which do not require physical contact. In 2013, the Leap Motion Controller (Leap Motion, Inc, San Francisco, CA) was launched. It is a device to detect the position and gestures. The Leap Motion Controller, with its API (application programmer interface), detects the position of predetermined objects (hands, fingers, instruments, pens) in a Cartesian plane in real time and reports discrete positions, gestures, and motion. The system consists of 3 infrared light transmitters and 2 infrared cameras (optical tracking system based on stereo vision), which can be classified as an optical tracking system based on the stereo vision principle. Among its applications the manipulation of medical images in dental surgery, urology, orthopedics, and general and hand surgery have been described as well as for manipulation of images during the making of angiography procedures and autopsies. Vargas and Vivas were the first to publish the use of the Leap Motion for the manipulation of a virtual surgical robot. Currently within the framework of the PhD program in e-Learning at the Universitat Oberta de Catalunya, an interdisciplinary working group formed by a pediatric surgeon, engineers, and education experts is designing a virtual 3D online environment for learning basic motor skills in minimally invasive surgery, using exercises from the Minimally Invasive Surgery Trainer-Virtual Reality and an additional from the Fundamentals of Laparoscopic Surgery program. The environment is designed in Unity, and it is used as the device for interaction with the laparoscopic surgery forceps of the Leap Motion Controller. In the current phase, the metrics and the feedback to proceed to make the studies of subjective and objective validation are taking place (Figure 1). If it is possible to demonstrate that the 3D online environments mediated by NUIs allow the learning of motor skills in minimally invasive surgery, a new research field and development in the area of surgical simulation will be opened. On the other hand, the dream of learning motor skills everywhere anytime with low-cost devices 639145 SRIXXX10.1177/1553350616639145Surgical InnovationAlvarez-Lopez et al letter2016
