BACKGROUND: Within the United Kingdom's National Health System (NHS), patients suffering from obesity may be provided with bariatric surgery. After receiving surgery many of these patients require further support to continue to lose more weight or to maintain a healthy weight. Remotely monitoring such patients' physical activity and other health-related variables could provide healthworkers with a more 'ecologically valid' picture of these patients' behaviours to then provide more personalised support. The current study assesses the feasibility of two smartphone apps to do so. In addition, the study looks at the barriers and facilitators patients experience to using these apps effectively. METHODS: Participants with a BMI > 35 kg/m2 being considered for and who had previously undergone bariatric surgery were recruited. Participants were asked to install two mobile phone apps. The 'Moves' app automatically tracked participants' physical activity and the 'WLCompanion' app prompted participants to set goals and input other health-related information. Then, to learn about participants' facilitators and barriers to using the apps, some participants were asked to complete a survey informed by the Theoretical Domains Framework. The data were analysed using regressions and descriptive statistics. RESULTS: Of the 494 participants originally enrolled, 274 participants data were included in the analyses about their activity pre- and/or post-bariatric surgery (ages 18-65, M = 44.02, SD ± 11.29). Further analyses were performed on those 36 participants whose activity was tracked both pre- and post-surgery. Participants' activity levels pre- and post-surgery did not differ. In addition, 54 participants' survey responses suggested that the main facilitator to their continued use of the Moves app was its automatic nature, and the main barrier was its battery drain. CONCLUSIONS: The current study tracked physical activity in patien

Childhood obesity is a major public health concern; behavioural interventions induce weight reduction in some, but success is variable. Heart rate variability (HRV) has been associated with impulse control and extent of dieting success. This study investigated the relationship between HRV and post childhood obesity intervention weight-management success, and involved recording the frequency-domain HRV measures ratio between low frequency and high frequency power (LF/HF) and high frequency power (HF), and the time-domain measure, percentage of successive beat-to-beat intervals that differ by more than 50ms (PNN50). It was expected that greater LF/HF and lower HF would be associated with greater post-intervention weight gain, and that greater PNN50 would be associated with greater impulse control. Seventy-four participants aged 9–14 (M=10.7; s.d.: 1.1) attended a weight-management camp, where HRV was recorded. Stop signal reaction time (SSRT) was also recorded as a measure of impulse control. As expected, SSRT was positively associated with pre-intervention body mass (r=0.301, P=0.010) and negatively associated with PNN50 (β=0.29, P=0.031). Post-intervention body mass change was positively associated with LF/HF (β=0.34, P=0.037), but was not associated with HF. Lifestyle interventions may have a greater chance of effectively supporting long-term weight-management for children with lower LF/HF; assessing HRV of obese children may be helpful in informing obesity treatment decisions.
Taylor D, Murphy J, Ahmad M, et al., 2016, Quantified-self for obesity: physical activity behaviour sensing to improve health outcomes, Publisher: IOS Press, Pages: 414-416, ISSN: 1879-8365
Physical activity levels in bariatric patients have not been well documented, despite their importance in maintaining weight loss following surgery. This study investigated the feasibility of tracking physical activity using a smartphone app with minimal user interaction. Thus far, we have obtained good quality data from 255 patients at various points in their weight loss journey. Preliminary analyses indicate little change in physical activity levels following surgery with pre-surgery patients reaching an average of 16 minutes per day and post-surgery patients achieving a daily average of 21 minutes. Further analyses using machine-learning techniques will be conducted to determine whether physical activity is a critical factor in distinguishing between successful and unsuccessful weight loss outcomes and in the resolution of comorbid conditions in patients with similar clinical profiles.
Taylor MJ, Taylor D, Gamboa P, et al., 2016, Using Motion-Sensor Games to Encourage Physical Activity for Adults with Intellectual Disability., Medicine Meets Virtual Reality 22, Publisher: IOS Press Ebooks, Pages: 417-423, ISBN: 978-1-61499-625-5
Adults with Intellectual Disability (ID) are at high risk of being in poor health as a result of exercising infrequently; recent evidence indicates this is often due to there being a lack of opportunities to exercise. This pilot study involved an investigation of the use of motion-sensor game technology to enable and encourage exercise for this population. Five adults (two female; 3 male, aged 34-74 [M = 55.20, SD = 16.71] with ID used motion-sensor games to conduct exercise at weekly sessions at a day-centre. Session attendees reported to have enjoyed using the games, and that they would like to use the games in future. Interviews were conducted with six (four female; two male, aged 27-51 [M = 40.20, SD = 11.28]) day-centre staff, which indicated ways in which the motion-sensor games could be improved for use by adults with ID, and barriers to consider in relation to their possible future implementation. Findings indicate motion-sensor games provide a useful, enjoyable and accessible way for adults with ID to exercise. Future research could investigate implementation of motion-sensor games as a method for exercise promotion for this population on a larger scale.
Taylor MJ, Arriscado D, Vlaev I, et al., 2016, Measuring perceived exercise capability and investigating its relationship with childhood obesity: a feasibility study, International Journal of Obesity, Vol: 40, Pages: 34-38, ISSN: 1476-5497
Background/Objectives: According to the COM-B ('Capability', 'Opportunity', 'Motivation' and 'Behaviour') model of behaviour, three factors are essential for behaviour to occur: capability, opportunity and motivation. Obese children are less likely to feel capable of exercising. The implementation of a new methodological approach to investigate the relationship between perceived exercise capability (PEC) and childhood obesity was conducted, which involved creating a new instrument, and demonstrating how it can be used to measure obesity intervention outcomes.Subjects/Methods: A questionnaire aiming to measure perceived exercise capability, opportunity and motivation was systematically constructed using the COM-B model and administered to 71 obese children (aged 9–17 years (12.24±0.2.01), body mass index (BMI) standard deviation scores (SDS) 2.80±0.660) at a weight-management camp in northern England. Scale validity and reliability was assessed. Relationships between PEC, as measured by the questionnaire, and BMI SDS were investigated for the children at the weight-management camp, and for 45 Spanish schoolchildren (aged 9–13 years, (10.52±1.23), BMI SDS 0.80±0.99). A pilot study, demonstrating how the questionnaire can be used to measure the effectiveness of an intervention aiming to bring about improved PEC for weight-management camp attendees, was conducted. No participants withdrew from these studies.Results: The questionnaire domain (exercise capability, opportunity and motivation) composite scales were found to have adequate internal consistency (a=0.712–0.796) and construct validity (χ2/degrees of freedom=1.55, root mean square error of approximation=0.072, comparative fit index=0.92). Linear regression revealed that low PEC was associated with higher baseline BMI SDS for both UK (b=−0.289, P=0.010) and Spanish (b=−0.446, P=0.047) participants. Pilot study findings provide preliminary evidence for P

BACKGROUND Mass casualty incidents are unfortunately becoming more common. The coordination of mass casualty incident response is highly complex. Currently available options for training, however, are limited by either lack of realism or prohibitive expense and by a lack of assessment tools. Virtual worlds represent a potentially cost-effective, immersive, and easily accessible platform for training and assessment. The aim of this study was to assess feasibility of a novel virtual-worlds–based system for assessment and training in major incident response.METHODS Clinical areas were modeled within a virtual, online hospital. A major incident, incorporating virtual casualties, allowed multiple clinicians to simultaneously respond with appropriate in-world management and transfer plans within limits of the hospital’s available resources. Errors, delays, and completed actions were recorded, as well as Trauma-NOnTECHnical Skills (T-NOTECHS) score. Performance was compared between novice and expert clinician groups.RESULTS Twenty-one subjects participated in three simulations: pilot (n = 7), novice (n = 8), and expert groups (n = 6). The novices committed more critical events than the experts, 11 versus 3, p = 0.006; took longer to treat patients, 560 (299) seconds versus 339 (321) seconds, p = 0.026; and achieved poorer T-NOTECHS scores, 14 (2) versus 21.5 (3.7), p = 0.003, and technical skill, 2.29 (0.34) versus 3.96 (0.69), p = 0.001. One hundred percent of the subjects thought that the simulation was realistic and superior to existing training options.CONCLUSION A virtual-worlds–based model for the training and assessment of major incident response has been designed and validated. The advantages of customizability, reproducibility, and recordability combined with the low cost of implementation suggest that this potentially represents a powerful adjunct to existing training methods and may be applicable to further areas of surgery as well.

Students applying to medical school may benefit from a better understanding of the clinical environment and the duties of a doctor. Despite attachments at hospital they may feel detached from the decision making process which is a pivotal part of being a clinician. A simulated hospital environment was tried on 30 pre-med students from an urban environment to test the feasibility of using structured clinical scenarios to augment their experience of a clinical setting.

Childhood obesity is a serious problem in the UK, with around 20% of children aged 10-11 being overweight or obese. Lifestyle interventions can be effective, but there is limited evidence of their effectiveness in delivering sustained weight loss. The present research explored potential of web-based, 3-dimensional virtual worlds (VWs) for facilitation of weight-management, well-being and patient and public involvement (PPI) for young people. Attendees of a weight management camp took part in induction sessions for use of the VW of Second Life. All participants successfully learned how to interact with one another and navigate the virtual environment. Participant appraisals of Second Life were varied. Some found it complicated and difficult to use, and some found it fun and the majority stated that they would choose to use VWs again. There is considerable potential for use of VWs to promote weight management, and Second Life or a similar VW could be used to deliver this. Potential barriers include members of the target sample having limited access to computers with necessary system requirements for running VWs, and that some may find VW-based educational experiences unappealing or challenging to navigate. For some however, VWs may provide a useful mode for provision of education, PPI and support relating to weight management.

Patient and public involvement is fundamental in healthcare and many methods attempt to facilitate this engagement. The present study investigated use of computer-generated environments known as 'virtual worlds' (VW) as an involvement method. The VW used in the present research was Second Life, which is 3-dimensional, publically accessible and internet-based. It is accessed using digital self-representations, or 'avatars', through which users navigate the virtual environment and communicate with one another. Participants were patients with long-term conditions, frequently involved in shaping health research and care. Some had mobility and communication difficulties, potentially making involvement through traditional face-to-face modes of engagement challenging. There were 2 stages to this study. Stage-1: Participants were introduced to VWs and Second Life. This was followed by a face-to-face focus group discussion (FGD) in order to gain their views on use of SL. Stage-2: An FGD attended by 8 people (4 patients, 3 researchers, 1 healthcare professional) was conducted in Second Life. Training and support on using Second Life had been provided for participants. The FGD took place successfully, although some technical and communication difficulties were experienced. Data was collected in the form of interviews and questionnaires from the patients about their experience of using the virtual world. Participants recognised the potential of VWs as a platform for patient engagement, especially for those who suffer from chronic conditions that impact severely upon their mobility and communication. Participant feedback indicated that potential barriers include technical problems with VW programs and potential user inexperience of using VWs, which may be counteracted by ensuring provision of continuous training and support. In conclusion, this study established the feasibility of using VWs for patient FGDs and indicates a potential of use of VWs for engagement in future, partic

Forty nurses were subsequently recruited to participate within the simulation and assess its feasibility.
Taylor D, Hall V, Conboy-Hill S, 2011, Using Virtual Reality to Provide Health Care Information to People With Intellectual Disabilities: Acceptability, Usability, and Potential Utility, Journal of Medical Internet Research, Vol: 4
Background: People with intellectual disabilities have poor access to health care, which may be further compromised by a lack of accessible health information. To be effective, health information must be easily understood and remembered. People with intellectual disabilities learn better from multimodal information sources, and virtual reality offers a 3-dimensional (3D) computer-generated environment that can be used for providing information and learning. To date, research into virtual reality experiences for people with intellectual disabilities has been limited to skill-based training and leisure opportunities within the young to mid age ranges.Objective: This study assessed the acceptability, usability, and potential utility of a virtual reality experience as a means of providing health care-related information to people with intellectual disabilities. We designed a prototype multimodal experience based on a hospital scenario and situated on an island in the Second Life 3D virtual world. We wanted to know how people of different ages and with varying levels of cognitive function would participate in the customized virtual environment, what they understood from being there, and what they remembered a week later.Methods: The study drew on qualitative data. We used a participatory research approach that involved working alongside people with intellectual disabilities and their supporters in a community setting. Cognitive function was assessed, using the Matrix Analogies Test and the British Picture Vocabulary Scale, to describe the sample. Participants, supported by facilitators, were video recorded accessing and engaging with the virtual environment. We assessed recall 1 week later, using a specialized interview technique. Data were downloaded into NVivo 8 and analyzed using the framework analysis technique.Results: Study participants were 20 people aged between 20 and 80 years with mild to severe intellectual disabilities. All participants were able to access th
BackgroundThis study assessed the implementation of a theater induction curriculum through a didactic lecture, an online Second Life operating room, and a simulated operating suite.MethodsSixty operating room novices were randomized into 4 groups: control (n = 15), didactic lecture (n = 15), Second Life (n = 15), and simulated operating suite (n = 15). The study followed a pretest and posttest design with a training intervention between operating room attendances. Outcome measures were knowledge, skills, and attitudes, measured using observed behavior and a self-report scale, with knowledge further assessed using multiple-choice questionnaires.ResultsThe lecture, Second Life, and simulated operating suite groups demonstrated significant improvements in all outcome measures. After the intervention, these 3 groups had significantly higher behavior (P < .001), self-report (P < .05), and knowledge (P < .05) scores than the control group.ConclusionsThis study demonstrates the value of delivering a theater induction curriculum for operating room preparation.

The development and use of virtual patients has become more expansive. Previous strategies to aid their development have been described to aid their formation. This study describes the development of a series of virtual patients following a methodology proposed by Posel et al . Ten virtual patients with surgical pathology were developed using a reproducible framework. This article serves to guide virtual patient authors as a working description of virtual patient design in order to assist them for future virtual patient development.
Taylor D, Patel V, Cohen D, et al., 2011, Single and multi-user virtual patient design in the virtual world, Studies in Health Technology and Informatics, Vol: 163: Medicine Meets Virtual Reality 18, Pages: 650-652
This research addresses the need for the flexible creation of immersive clinical training simulations for multiple interacting participants and virtual patients by using scalable open source virtual world technologies. Initial development of single-user surgical virtual patients has been followed by that of multi-user multiple casualties in a field environment and an acute hospital emergency department. The authors aim to validate and extend their reproducible framework for eventual application of virtual worlds to whole hospital major incident response simulation and to multi-agency, pan-geographic mass casualty exercises.
