Feasibility of a virtual reality-based exercise intervention and low-cost motion tracking method for estimation of motor proficiency in youth with autism spectrum disorder.

BACKGROUND: Motor impairment is widely acknowledged as a core feature in children with autism spectrum disorder (ASD), which can affect adaptive behavior and increase severity of symptoms. Low-cost motion capture and virtual reality (VR) game technologies hold a great deal of promise for providing personalized approaches to motor intervention in ASD. The present study explored the feasibility, acceptability and potential efficacy of a custom-designed VR game-based intervention (GaitWayXR™) for improving gross motor skills in youth with ASD. METHODS: Ten children and adolescents (10-17 years) completed six, 20-min VR-based motor training sessions over 2 weeks while whole-body movement was tracked with a low-cost motion capture system. We developed a methodology for using motion tracking data to quantify whole-body movement in terms of efficiency, synchrony and symmetry. We then studied the relationships of the above quantities with standardized measures of motor skill and cognitive flexibility. RESULTS: Our results supported our presumption that the VR intervention is safe, with no adverse events and very few minor to moderate side-effects, while a large proportion of parents said they would use the VR game at home, the most prohibitive reasons for adopting the system for home therapy were cost and space. Although there was little evidence of any benefits of the GaitWayXR™ intervention in improving gross motor skills, we showed several positive correlations between the standardized measures of gross motor skills in ASD and our measures of efficiency, symmetry and synchrony from low-cost motion capture. CONCLUSIONS: These findings, though preliminary and limited by small sample size, suggest that low-cost motion capture of children with ASD is feasible with movement exercises in a VR-based game environment. Based on these preliminary findings, we recommend conducting larger-scale studies with methods for improving adherence to VR gaming interventions over longer periods.

Special delivery: an analysis of mHealth in maternal and newborn health programs and their outcomes around the world.

Mobile health (mHealth) encompasses the use of mobile telecommunication and multimedia into increasingly mobile and wireless health care delivery systems and has the potential to improve tens of thousands of lives each year. The ubiquity and penetration of mobile phones presents the opportunity to leverage mHealth for maternal and newborn care, particularly in under-resourced health ecosystems. Moreover, the slow progress and funding constraints in attaining the Millennium Development Goals for child and maternal health encourage harnessing innovative measures, such as mHealth, to address these public health priorities. This literature review provides a schematic overview of the outcomes, barriers, and strategies of integrating mHealth to improve prenatal and neonatal health outcomes. Six electronic databases were methodically searched using predetermined search terms. Retrieved articles were then categorized according to themes identified in previous studies. A total of 34 articles and reports contributed to the findings with information about the use and limitations of mHealth for prenatal and neonatal healthcare access and delivery. Health systems have implemented mHealth programs to facilitate emergency medical responses, point-of-care support, health promotion and data collection. However, the policy infrastructure for funding, coordinating and guiding the sustainable adoption of prenatal and neonatal mHealth services remains under-developed. The integration of mobile health for prenatal and newborn health services has demonstrated positive outcomes, but the sustainability and scalability of operations requires further feedback from and evaluation of ongoing programs.

Innovation spaces: six strategies to inform health care.

Innovation remains an understudied resource within health care. Furthermore, the goals of US health care reform make innovation vitally important, while the time and resource limitations characteristic of health care make new strategies for innovation both necessary and potentially highly meaningful. The purpose of this study was to examine strategies for innovation in various industries and draw lessons for improving innovation in health care. This qualitative study began with literature research that provided a framework for discussion and identified a recurrent challenge in innovation: balancing the freedom to be creative with the need for structured management of ideas. Researchers then identified leading innovative companies and conducted phone interviews with innovation officers and other experts about their strategies for addressing the major innovation challenge. This article breaks out innovation strategies into 6 categories (dedicated times, formal teams, outside ideas, idea-sharing platforms, company/job goals, and incentives) and evaluates them for levels of control, yield, and pervasiveness. Based on this analysis, recommendations are offered for improving innovation in health care, calling for employee time allocated to innovation, dedicated innovation teams, and the incorporation of outside ideas.

Comparison Between QT and Corrected QT Interval Assessment by an Apple Watch With the AccurBeat Platform and by a 12­Lead Electrocardiogram With Manual Annotation: Prospective Observational Study.

BACKGROUND: Abnormal prolongation or shortening of the QT interval is associated with increased risk for ventricular arrhythmias and sudden cardiac death. For continuous monitoring, widespread use, and prevention of cardiac events, advanced wearable technologies are emerging as promising surrogates for conventional 12­lead electrocardiogram (ECG) QT interval assessment. Previous studies have shown a good agreement between QT and corrected QT (QTc) intervals measured on a smartwatch ECG and a 12-lead ECG, but the clinical accuracy of computerized algorithms for QT and QTc interval measurement from smartwatch ECGs is unclear. OBJECTIVE: The prospective observational study compared the smartwatch-recorded QT and QTc assessed using AccurKardia's AccurBeat platform with the conventional 12­lead ECG annotated manually by a cardiologist. METHODS: ECGs were collected from healthy participants (without any known cardiovascular disease) aged >22 years. Two consecutive 30-second ECG readings followed by (within 15 minutes) a 10-second standard 12-lead ECG were recorded for each participant. Characteristics of the participants were compared by sex using a 2-sample t test and Wilcoxon rank sum test. Statistical comparisons of heart rate (HR), QT interval, and QTc interval between the platform and the 12-lead ECG, ECG lead I, and ECG lead II were done using the Wilcoxon sign rank test. Linear regression was used to predict QTc and QT intervals from the ECG based on the platform's QTc/QT intervals with adjustment for age, sex, and difference in HR measurement. The Bland-Altman method was used to check agreement between various QT and QTc interval measurements. RESULTS: A total of 50 participants (32 female, mean age 46 years, SD 1 year) were included in the study. The result of the regression model using the platform measurements to predict the 12-lead ECG measurements indicated that, in univariate analysis, QT/QTc intervals from the platform significantly predicted QT/QTc intervals from the 12-lead ECG, ECG lead I, and ECG lead II, and this remained significant after adjustment for sex, age, and change in HR. The Bland-Altman plot results found that 96% of the average QTc interval measurements between the platform and QTc intervals from the 12-lead ECG were within the 95% confidence limit of the average difference between the two measurements, with a mean difference of -10.5 (95% limits of agreement -71.43, 50.43). A total of 94% of the average QT interval measurements between the platform and the 12-lead ECG were within the 95% CI of the average difference between the two measurements, with a mean difference of -6.3 (95% limits of agreement -54.54, 41.94). CONCLUSIONS: QT and QTc intervals obtained by a smartwatch coupled with the platform's assessment were comparable to those from a 12-lead ECG. Accordingly, with further refinements, remote monitoring using this technology holds promise for the identification of QT interval prolongation.

Consumer acceptance of using a digital technology to manage postpartum depression.

The goal of the study was to evaluate the end user experience using the MamaLift Plus app for 2 weeks to support the treatment of their postpartum depression (PPD). A total of 14 participants completed the study and their experiences are reported in this publication. Participants reported that MamaLift Plus is an acceptable, highly usable, and practical mobile tool to use weekly for the management of their PPD. More research is warranted to evaluate the benefit of digital behavior health interventions, especially in patient populations where mental health care may be limited or harder to access by patients.

A Comparative Evaluation of Measurement-Based Psychiatric Care Delivered via Specialized Telemental Health Platform Versus Treatment As Usual: A Retrospective Analysis.

Background and objective A significant proportion of the adult population in the United States (US) live with some form of mental illness. The more prevalent conditions of depression and anxiety are typically managed in primary care settings rather than specialty care. The aim of this study was to determine the efficacy of a novel, measurement-driven psychiatric treatment platform delivered via an online telemental health platform as compared to treatment as usual (TAU). Methods The TAU dataset and the telemental health platform (Brightside) dataset were constructed based on the total populations of adult patients receiving care for depression from January 2018 through December 2020 (November 2018 through March 2021 for the Brightside group). Patients in both groups had a primary mental health diagnosis of depression and the presence of a positive screen for depression as measured by the Patient Health Questionnaire-9 (PHQ-9) upon initiation of treatment. HITLAB, an independent digital health verification and testing lab, conducted comparative analyses of the two groups using the Chi-square test of independence. Results Close to 80% of telemental health platform patients experienced a reduction of 5 or more points from their baseline PHQ-9 score as compared to 52% of TAU patients. The mean reduction in PHQ-9 score was slightly higher in the Brightside group (-11.5) versus the TAU group (-10.1). Chi-square tests of independence [x2 (1, n=6281) = 256.75, p≤0.001] for meaningful reduction and for remission [x2 (1, n=6281) = 105.50 p≤0.001] were highly significant. Conclusion The telemental health platform patients performed significantly better than those under psychiatric TAU in terms of reduction in symptoms of depression in adults.

Barriers to cross--institutional health information exchange: a literature review.

While the development of health information technology, particularly electronic health records (EHR), is a triumph for the advancement of healthcare, non-interoperable clinical data systems lead to fragmented communication and incomplete records. If interoperable HIT systems could be achieved integrated HIT could be leveraged to lessen medical errors, improve patient care and optimize epidemiological research. To understand the barriers to interoperability or health information exchange (HIE), we reviewed the literature on HIT and barriers to HIE. Our search yielded 492 articles, 25 meeting our inclusion criteria. In general, we found that the predominant barriers to HIE are need for standards, security concerns, economic loss to competitors, and federated systems. Research on interoperability is limited because most HIE programs are still in formative stages. More research is needed to fully understand interoperability of HIT, how to overcome the barriers to interoperability, and how to design HIT to better facilitate HIE.

The prevalence and impact of anergia (lack of energy) in subjects with heart failure and its associations with actigraphy.

BACKGROUND: Anergia (lack of energy) is a newly delineated, criterion-based geriatric syndrome. Because heart failure (HF) is a common chronic condition among older adults and a because a cardinal symptom of HF is reduced energy, we characterized the degree of anergia in subjects with HF and evaluated its relevance to disease severity, functional performance, and quality of life. METHODS AND RESULTS: Prospective 3-month cohort study among a convenience sample of 61 subjects (61 +/- 15 years, 48% women, ejection fraction 41 +/- 16%) with New York Heart Association (NYHA) Class I-III HF were studied. The criterion for anergia was based on the major criterion "sits around for lack of energy" and any 2 of 6 minor criteria. Principal measures in addition to demographic and clinical characteristics included functional performance (NYHA class, 6-minute walk, cardiopulmonary exercise testing), plasma B-type natriuretic peptide, and quality of life (SF-12 and Minnesota Living with Heart Failure Questionnaire). To evaluate the relevance of anergia to daily function, each subject wore an Actigraph, a watch-like wrist device that continuously and automatically monitors patient activity levels and energy expenditure, for 3 months. Anergia was prevalent in 39% of this population. Anergia was associated with decrements in functional capacity (higher NYHA Class and lower 6-minute walk distance) as well as reduction in quality of life, but was not associated with ejection fraction. Actigraphy data demonstrated that HF subjects with anergia spent significantly less time performing moderate physical activity and the peak activity counts per day were significantly lower than HF subjects without anergia. Additionally, the amplitude of circadian rhythm was lower, suggesting altered sleep and activity patterns in HF subjects with anergia compared with those without anergia. Over the 3 months of follow-up, there was a significant association between anergia and intercurrent hospitalization. CONCLUSIONS: Anergia is significantly associated with several of the cardinal domains of HF. Its presence is associated with demonstrable differences in both physical activity and circadian rhythm as measured by actigraphy and an increased risk of hospitalizations. Accordingly, anergia may be a target for intervention among HF subjects.

Understanding communication capacity. Communication patterns and ICT usage in clinical settings.

Organizational complexity and interruptive workflows present challenges to communication in clinical workspaces, compromising healthcare quality and cost, and potentially leading to negative patient outcomes. To understand how information communication technology (ICT) could be improved, we reviewed the literature on inter-clinician communication problems, impacts on clinical workflows, ICT usage and barriers to communication. Our search yielded more than 300 articles; 98 met our inclusion criteria. In general, we found that clinical communication tends to flow along synchronous channels and is highly interruptive. Both electronic and non-electronic solutions to communication problems have met with mixed results. Implementation failures have been linked to barriers to technology adoption, including such factors as age, gender and computer experience. More research is needed to understand how improved communication reduces adverse clinical events and healthcare costs. Cost-effective ICTs to improve communication efficiency and workflow patterns in healthcare settings have great potential to enhance quality of care and reduce medical costs.

The Impact of Wearable Device Enabled Health Initiative on Physical Activity and Sleep.

OBJECTIVES: The Personal Health Management Study (PHMS) is an assessment of the effect of a voluntary employee-facing health initiative using a commercially-available wearable device implemented among 565 employees of Boehringer Ingelheim Pharmaceuticals, Inc. The results of the initiative on physical activity (measured as steps) and sleep is reported. METHODS: This was a 12-month, prospective, single-cohort intervention study using a wearable activity-measuring device tracking steps and sleep (entire study period) and a system of health-promoting incentives (first nine months of study period). The findings from the first nine study months are reported. RESULTS: The mixed model repeated measures approach was used to analyze the data. There was no significant difference in steps between the first month (7915.6 mean steps per person per day) and the last month (7853.4 mean steps per person per day) of the intervention. However, there was a seasonal decline in steps during the intervention period from fall to winter, followed by an increase in steps from winter to spring. In contrast, sleep tended to increase steadily throughout the study period, and the number of hours slept during the last month (7.52 mean hours per person per day) of the intervention was significantly greater than the number of hours slept during the first month (7.16 mean hours per person per day). CONCLUSIONS: The impact of the initiative on physical activity and sleep differed over the period of time studied. While physical activity did not change between the first and last month of the intervention, the number of hours slept per night increased significantly. Although seasonal changes and study-device habituation may explain the pattern of change in physical activity, further evaluation is required to clarify the reasons underlying the difference in the impact of the initiative on the dynamics of steps and sleep.

Do patients "like" good care? measuring hospital quality via Facebook.

With the growth of Facebook, public health researchers are exploring the platform's uses in health care. However, little research has examined the relationship between Facebook and traditional hospital quality measures. The authors conducted an exploratory quantitative analysis of hospitals' Facebook pages to assess whether Facebook "Likes" were associated with hospital quality and patient satisfaction. The 30-day mortality rates and patient recommendation rates were used to quantify hospital quality and patient satisfaction; these variables were correlated with Facebook data for 40 hospitals near New York, NY. The results showed that Facebook "Likes" have a strong negative association with 30-day mortality rates and are positively associated with patient recommendation. These exploratory findings suggest that the number of Facebook "Likes" for a hospital may serve as an indicator of hospital quality and patient satisfaction. These findings have implications for researchers and hospitals looking for a quick and widely available measure of these traditional indicators.

Falling short: recruiting elderly individuals for a fall study.

Despite the importance of movement and activity indicators in predicting the risk of falls in older adults, collection and analysis of such data are limited. The dearth may result from recruitment challenges faced by fall-related studies that capture data on movement and activity in older adults. This article addresses recruitment and sampling methodology issues and draws attention to the gap in best practices left by previous literature. Authors conducted a systematic review of methods used to recruit elderly individuals for "activity-related fall studies" that assessed subjects' movement and mobility, and investigated incidence of real falls. The review highlighted effective recruitment strategies and identified challenges across several settings. Literature review findings were compared to recruitment challenges encountered in an activity-related fall study from 2011, focused on enrolling a target group of older adults with both high risk of falling and the requisite cognitive capacity to adhere to activity protocols. The analysis yielded several recommendations for improving recruitment of older adults for activity-related fall studies, including: recruiting from community-based settings; utilizing short-term activity protocols to promote involvement among institutionalized elderly; establishing eligibility criteria that may include those with lower cognitive functioning, mobility restrictions, and co-morbidities; employing direct-mail recruitment methods; and utilizing intermediaries to recruit institutionalized elderly.

How will we know if it's working? A multi-faceted approach to measuring usability of a specialty-specific electronic medical record.

The most effective use of electronic medical records (EMRs) will result from wide-scale adoption and appropriate use of the technology-two factors that rely heavily on a system's usability. We conducted a qualitative and quantitative usability assessment of an EMR developed specifically for treating the HIV/AIDS patient population. The purpose of this study was to inform developers on how to prioritize resources for their impending software rebuild initiative and to evaluate a dual methodology consisting of both quantitative and qualitative components. The results indicated that the methodology was valid, although there were some variations recommended for future usability assessments of EMRs. The study also underscored the need to assess usability based on user feedback and to employ multiple methods to elicit information; this research revealed many insights into the software that contradicted initial assumptions and also found that asking questions in multiple ways yielded more complete feedback.

"Think different": a qualitative assessment of commercial innovation for diabetes information technology programs.

BACKGROUND: This study reviews the state of diabetes information technology (IT) initiatives and presents a set of recommendations for improvement based on interviews with commercial IT innovators. MATERIALS AND METHODS: Semistructured interviews were conducted with 10 technology developers, representing 12 of the most successful IT companies in the world. Average interview time was approximately 45 min. Interviews were audio-recorded, transcribed, and entered into ATLAS.ti for qualitative data analysis. Themes were identified through a process of selective and open coding by three researchers. RESULTS: We identified two practices, common among successful IT companies, that have allowed them to avoid or surmount the challenges that confront healthcare professionals involved in diabetes IT development: (1) employing a diverse research team of software developers and engineers, statisticians, consumers, and business people and (2) conducting rigorous research and analytics on technology use and user preferences. CONCLUSIONS: Because of the nature of their respective fields, healthcare professionals and commercial innovators face different constraints. With these in mind we present three recommendations, informed by practices shared by successful commercial developers, for those involved in developing diabetes IT programming: (1) include software engineers on the implementation team throughout the intervention, (2) conduct more extensive baseline testing of users and monitor the usage data derived from the technology itself, and (3) pursue Institutional Review Board-exempt research.

A review of the use of mobile phone text messaging in clinical and healthy behaviour interventions.

We reviewed the literature on the use of text messaging for clinical and healthy behaviour interventions. Electronic databases were searched in December 2009 using keywords related to text messaging and health interventions. The final review included 24 articles. Of those, seven covered medication adherence, eight discussed clinical management and nine reported on health-related behaviour modification. Sixteen were randomized controlled trials (RCT), five were non-controlled pre-post comparison studies and three were feasibility pilots not reporting a behavioural outcome. The frequency of messaging ranged from multiple messages daily to one message per month. Among the 16 RCTs, 10 reported significant improvement with interventions and six reported differences suggesting positive trends. Text messaging received good acceptance and showed early efficacy in most studies. However, the evidence base is compromised by methodological limitations and is not yet conclusive.

Maximum daily 6 minutes of activity: an index of functional capacity derived from actigraphy and its application to older adults with heart failure.

OBJECTIVES: To compare the correlation between the maximum 6 minutes of daily activity (M6min) and standard measures of functional capacity in older adults with heart failure (HF) with that in younger subjects and its prognostic utility. DESIGN: Prospective, cohort study. SETTING: Tertiary care, academic HF center. PARTICIPANTS: Sixty, ambulatory, adults, New York Heart Association (NYHA) Class I to III, stratified into young (50.9 +/- 9.4) and older cohorts (76.8 +/- 8.0). MEASUREMENTS: Correlation between M6min and measures of functional capacity (6-minute walk test; 6MWT) and peak oxygen consumption (VO(2)) according to cardiopulmonary exercise testing in a subset of subjects. Survival analysis was employed to evaluate the association between M6min and adverse events. RESULTS: Adherence to actigraphy was high (90%) and did not differ according to age. The correlation between M6min and 6MWT was higher in subjects aged 65 and older than in those younger than 65 (correlation coefficient (r=0.702, P<.001 vs r=0.490, P=.002). M6min was also significantly associated with peak VO(2) (r=0.612, P=.006). During the study, 26 events occurred (2 deaths, 10 hospitalizations, 8 emergency department visits, and 6 intercurrent illnesses). The M6min was significantly associated with subsequent events (hazard ratio=2.728, 95% confidence interval=1.10-6.77, P=.03), independent of age, sex, ejection fraction, NYHA class, brain natriuretic peptide, and 6MWT. CONCLUSION: The high adherence to actigraphy and association with standard measures of functional capacity and independent association with subsequent morbid events suggest that it may be useful for monitoring older adults with HF.

Synchronous communication facilitates interruptive workflow for attending physicians and nurses in clinical settings.

STUDY OBJECTIVE: Inter-clinician communication accounts for more than half of all information exchanges within the health care system. A non-participatory, qualitative time-and-motion observational study was conducted in order to gain a better understanding of inter-clinician communication behaviors, routine workflow patterns, and the use of information communication technologies (ICTs) within the clinical workspace. METHOD: Over a 5-day period, seven attending physicians and two nurses were shadowed for 2-4h at a time. Inter-clinician communication events were tracked in real-time using synchronized digital stopwatches. Observations were recorded on a paper-based, semi-structured observation tool and later coded for analysis. RESULTS: Nine hundred and eighty-seven communication events were observed over 2024.67 min. Clinicians were observed to spend the majority of their time on patient care (85.4% in this study) with about three-fourths of that time spent on indirect patient care (e.g. charting). Clinicians were observed to prefer using synchronous communication modes, which led to multitasking and created a highly interrupted workflow. Forty-two percent (n=415) of communication events were coded as interruptions and study participants were seen multitasking 14.8% of the time. Though each interruption was short-lived (on average 0.98+/-2.24 min for attending physicians), they occurred frequently. Both attending physicians and nurses were the recipients of more interruptions than they initiated. CONCLUSION: This study demonstrated that the clinical workspace is a highly interruptive environment. Multiple interruptions in the communication processes between clinicians consume time and have the potential to increase the risk of error. This workflow analysis may inform the development of communication devices to enhance inter-clinician communication by reducing interruptions or deferring interruptions to more appropriate times.
