RESUMEN

Patient-generated health data (PGHD) is data created, captured, or recorded by patients in between healthcare appointments, and is an important supplement to data generated during periodic clinical encounters. PGHD has potential to improve diagnosis and management of chronic conditions, improve health outcomes, and facilitate more "connected health" between patients and their care teams. Electronic PGHD is rapidly accelerating due to the proliferation of consumer health technologies, remote patient monitoring systems, and personal health platforms. Despite this tremendous growth in PGHD and anticipated benefits, broadscale use of PGHD has been challenging to implement with significant gaps in current knowledge about how PGHD can best be employed in the service of high-quality, patient-centered care. While the role of PGHD in patient self-management continues to grow organically, we need a deeper understanding of how data collection and sharing translate into actionable information that supports shared decision-making and informs clinical care in real-world settings. This, in turn, will foster both clinical adoption and patient engagement with PGHD. We propose an agenda for PGHD-related research in the Veterans Health Administration that emphasizes this clinical value to enhance our understanding of its potential and limitations in supporting shared decision-making and informing clinical care.

RESUMEN

Although the availability of virtual care technologies in the Veterans Health Administration (VHA) continues to expand, ensuring engagement with these technologies among Veterans remains a challenge. VHA Health Services Research & Development convened a Virtual Care State of The Art (SOTA) conference in May 2022 to create a research agenda for improving virtual care access, engagement, and outcomes. This article reports findings from the Virtual Care SOTA engagement workgroup, which comprised fourteen VHA subject matter experts representing VHA clinical care, research, administration, and operations. Workgroup members reviewed current evidence on factors and strategies that may affect Veteran engagement with virtual care technologies and generated key questions to address evidence gaps. The workgroup agreed that although extensive literature exists on factors that affect Veteran engagement, more work is needed to identify effective strategies to increase and sustain engagement. Workgroup members identified key priorities for research on Veteran engagement with virtual care technologies through a series of breakout discussion groups and ranking exercises. The top three priorities were to (1) understand the Veteran journey from active service to VHA enrollment and beyond, and when and how virtual care technologies can best be introduced along that journey to maximize engagement and promote seamless care; (2) utilize the meaningful relationships in a Veteran's life, including family, friends, peers, and other informal or formal caregivers, to support Veteran adoption and sustained use of virtual care technologies; and (3) test promising strategies in meaningful combinations to promote Veteran adoption and/or sustained use of virtual care technologies. Research in these priority areas has the potential to help VHA refine strategies to improve virtual care user engagement, and by extension, outcomes.

RESUMEN

BACKGROUND: Video and other technologies are reshaping the delivery of health care, yet barriers related to workflow and possible provider fatigue suggest that a thorough evaluation is needed for quality and process improvement. OBJECTIVE: This scoping review explored the relationship among technology, fatigue, and health care to improve the conditions for providers. METHODS: A 6-stage scoping review of literature (from 10 databases) published from 2000 to 2020 that focused on technology, health care, and fatigue was conducted. Technologies included synchronous video, telephone, informatics systems, asynchronous wearable sensors, and mobile health devices for health care in 4 concept areas related to provider experience: behavioral, cognitive, emotional, and physical impact; workplace at the individual, clinic, hospital, and system or organizational levels; well-being, burnout, and stress; and perceptions regarding technology. Qualitative content, discourse, and framework analyses were used to thematically analyze data for developing a spectrum of health to risk of fatigue to manifestations of burnout. RESULTS: Of the 4221 potential literature references, 202 (4.79%) were duplicates, and our review of the titles and abstracts of 4019 (95.21%) found that 3837 (90.9%) were irrelevant. A full-text review of 182 studies revealed that 12 (6.6%) studies met all the criteria related to technology, health care, and fatigue, and these studied the behavioral, emotional, cognitive, and physical impact of workflow at the individual, hospital, and system or organizational levels. Video and electronic health record use has been associated with physical eye fatigue; neck pain; stress; tiredness; and behavioral impacts related to additional effort owing to barriers, trouble with engagement, emotional wear and tear and exhaustion, cognitive inattention, effort, expecting problems, multitasking and workload, and emotional experiences (eg, anger, irritability, stress, and concern about well-being). An additional 14 studies that evaluated behavioral, emotional, and cognitive impacts without focusing on fatigue found high user ratings on data quality, accuracy, and processing but low satisfaction with clerical tasks, the effort required in work, and interruptions costing time, resulting in more errors, stress, and frustration. Our qualitative analysis suggests a spectrum from health to risk and provides an outline of organizational approaches to human factors and technology in health care. Business, occupational health, human factors, and well-being literature have not studied technology fatigue and burnout; however, their findings help contextualize technology-based fatigue to suggest guidelines. Few studies were found to contextually evaluate differences according to health professions and practice contexts. CONCLUSIONS: Health care systems need to evaluate the impact of technology in accordance with the Quadruple Aim to support providers' well-being and prevent workload burden, fatigue, and burnout. Implementation and effectiveness approaches and a multilevel approach with objective measures for clinical, human factors, training, professional development, and administrative workflow are suggested. This requires institutional strategies and competencies to integrate health care quality, technology and well-being outcomes.

RESUMEN

Automated text messaging interventions can effectively improve self-care and were used to support the U.S. Veterans Health Administration's (VHA) public health outreach during the COVID pandemic. Currently, significant gaps exist in knowledge about VHA patients' texting protocol preferences that may impact user receptivity, engagement, and effectiveness. This study qualitatively evaluated patient suggestions to improve two VHA Covid-related texting interventions and preferences for future text message protocols. We reviewed cross-sectional type-written survey responses from patients receiving either the "Coronavirus Precautions" or the "Coping During COVID" multi-week text protocols. Two team members independently and inductively coded all responses allowing for an upward abstraction of qualitative data. Nine hundred five patients (72.8% male) responded to the open-response item questions targeted by this research. An item that sought feedback to improve protocol acceptability generated thirteen distinct descriptive categories (inter-rater reliability 83.5%). Codable feedback showed, for example, that patients desired to manipulate message frequency and to have a more sophisticated interaction with messages. Patients' suggestions for future automated text messaging protocols yielded nine distinct topic areas. Patients offered suggestions that may impact receptivity and engagement of future automated text message protocols, particularly as they relate to outreach during a public health crisis. In addition, patients offered specific topics they would like to see in future text message protocols. We discuss how the findings can be used to increase engagement in current and post-pandemic public health interventions.

RESUMEN

The shift to communication technologies during the pandemic has had positive and negative effects on clinical social worker practice. Best practices are identified for clinical social workers to maintain emotional well-being, prevent fatigue, and avoid burnout when using technology. A scoping review from 2000 to 21 of 15 databases focused on communication technologies for mental health care within four areas: (1) behavioral, cognitive, emotional, and physical impact; (2) individual, clinic, hospital, and system/organizational levels; (3) well-being, burnout, and stress; and (4) clinician technology perceptions. Out of 4795 potential literature references, full text review of 201 papers revealed 37 were related to technology impact on engagement, therapeutic alliance, fatigue and well-being. Studies assessed behavioral (67.5%), emotional (43.2%), cognitive (57.8%), and physical (10.8%) impact at the individual (78.4%), clinic (54.1%), hospital (37.8%) and system/organizational (45.9%) levels. Participants were clinicians, social workers, psychologists, and other providers. Clinicians can build a therapeutic alliance via video, but this requires additional skill, effort, and monitoring. Use of video and electronic health records were associated with clinician physical and emotional problems due to barriers, effort, cognitive demands, and additional workflow steps. Studies also found high user ratings on data quality, accuracy, and processing, but low satisfaction with clerical tasks, effort required and interruptions. Studies have overlooked the impact of justice, equity, diversity and inclusion related to technology, fatigue and well-being, for the populations served and the clinicians providing care. Clinical social workers and health care systems must evaluate the impact of technology in order to support well-being and prevent workload burden, fatigue, and burnout. Multi-level evaluation and clinical, human factor, training/professional development and administrative best practices are suggested.

RESUMEN

The assessment and treatment of traumatic brain injury (TBI) has become a difficult challenge for the DoD medical health system. Clinical neuropsychologists are being asked to make statements regarding a soldier's functional skills, ability to return to active duty, and competence in tasks of community living. Given the increasing prevalence of blast injuries to the head, and the fact that many brain injuries may have no external marker of injury, there is need for researching innovative assessment methods in detecting blast-related brain injury. To address these issues, two virtual reality-based Paced Auditory/Visual Serial Addition Tests (PA/VSAT) were developed that involve the participant being immersed in a Virtual Middle Eastern City as serial addition stimuli are presented. This study is an initial validation of the VRPASAT and VRPVSAT as assessments of neurocognitive functioning. When compared to the paper-and-pencil version of the test, as well as the Automated Neuropsychological Assessment Metrics, the VRPASAT and VRPVSAT appear to have enhanced capacity for providing an indication of a participant's performance while immersed in a military relevant simulation.

RESUMEN

Art workshops have been looked at before in terms of impact for people with dementia but never those conducted remotely during a pandemic lockdown. Two artists, working with local museums, provided Art workshops for people with dementia and their caregivers. Due to the first Covid 19 lockdown in the UK, the artists set up a weekly delivery service of Home Art Boxes to thirty-three people with dementia and their caregivers over a period spanning 11 months. The artists received funding from local organisations and the Community Lottery Fund. Thematic analysis of the feedback from the participants regarding the project and the artists themselves provided the data for this evaluation of the project. Seven main themes were identified: organisation of the project; community and connections; supporting the caregivers; enjoyment and enrichment; well-being and cognitive benefits of the projects; equipment and instructions; and drawbacks within the project. The participants' feedback enabled the artists to improve the contents and instructions given each week so that they were able to adjust the activities for those people with dementia whose condition was declining. Implications are that remote Art workshops are possible during lockdown restrictions, but that personal communication is equally important.

RESUMEN

Implementation efforts to increase adoption of health technologies (e.g., telehealth, mobile health, electronic health records, patient portals) have commonly focused on increasing the adoption of specific health technologies in specific service lines. To facilitate adoption of multiple health technologies across a hospital setting, four Virtual Health Resource Centers (VHRCs) were established to provide clinical adoption support to healthcare staff and patients in four hospitals in a large healthcare system. This study spanned a 3-year period, with the first half including pre-implementation efforts, and the second half involved in implementation efforts. In order to compare sites to the national population, a binomial regression was used which allowed for adjustment of relevant covariates (e.g., differences in number of enrollees, level of complexity of facility). The pre-implementation phase and the initial year-and-a-half of the implementation phase resulted in an increase in internal facilitators' knowledge and skills of virtual care technologies, an increase in facilitator and site capacity, and high levels of adherence to implementation strategies were maintained across sites. Virtual care utilization increased across all sites and across the healthcare system during the implementation phase; however, a comparison to the increase in national level virtual care utilization metrics yielded no meaningful difference. While many implementation strategies aim to increase the adoption of a particular health technology product (e.g., a particular app or remote monitoring use case), the establishment of VHRCs may increase efficiencies in delivery of virtual care training and consultation to healthcare staff and patients, which may increase capacity and decrease barriers to adoption. However, due to the impact of the COVID-19 pandemic on the need for rapid adoption of technology and decreased in person care and services, it is not yet known the longer term impact that the establishment of VHRCs may have on the sustained adoption of health technologies.

RESUMEN

Web-based self-care resources have a number of potential benefits for military service members (SMs) and their families such as convenience, anonymity, and immediate 24/7 access to useful information. There is limited data available, however, regarding SM and military healthcare provider use of online self-care resources. Our goal with this study was to conduct a preliminary survey assessment of self-care Web site awareness, general attitudes about use, and usage behaviors of Web-based self-care resources among SMs and military healthcare providers. Results show that the majority of SMs and providers use the Internet often, use Internet self-care resources, and are willing to use additional Web-based resources and capabilities. SMs and providers also indicated a preference for Web-based self-care resources as adjunct tools to face-to-face/in-person care. Data from this preliminary study are useful for informing additional research and best practices for integrating Web-based self-care for the military community.

RESUMEN

Sensor, wearable, and remote patient monitoring technologies are typically used in conjunction with video and/or in-person care for a variety of interventions and care outcomes. This scoping review identifies clinical skills (i.e., competencies) needed to ensure quality care and approaches for organizations to implement and evaluate these technologies. The literature search focused on four concept areas: (1) competencies; (2) sensors, wearables, and remote patient monitoring; (3) mobile, asynchronous, and synchronous technologies; and (4) behavioral health. From 2846 potential references, two authors assessed abstracts for 2828 and, full text for 521, with 111 papers directly relevant to the concept areas. These new technologies integrate health, lifestyle, and clinical care, and they contextually change the culture of care and training-with more time for engagement, continuity of experience, and dynamic data for decision-making for both patients and clinicians. This poses challenges for users (e.g., keeping up, education/training, skills) and healthcare organizations. Based on the clinical studies and informed by clinical informatics, video, social media, and mobile health, a framework of competencies is proposed with three learner levels (novice/advanced beginner, competent/proficient, advanced/expert). Examples are provided to apply the competencies to care, and suggestions are offered on curricular methodologies, faculty development, and institutional practices (e-culture, professionalism, change). Some academic health centers and health systems may naturally assume that clinicians and systems are adapting, but clinical, technological, and administrative workflow-much less skill development-lags. Competencies need to be discrete, measurable, implemented, and evaluated to ensure the quality of care and integrate missions.

RESUMEN

AIMS: Upon suspicion of infective endocarditis, the causative microorganism must be identified to optimize treatment. Blood cultures and culturing of removed valves are the mainstay of this diagnosis and should be complemented by growth-independent methods. We assessed the diagnostic benefit of examining removed endocarditis valves by broad-range bacterial PCR to detect causative bacteria in cases where culturing was not available, negative, or inconclusive because a skin commensal was detected, in patients from our clinical routine practice. METHODS AND RESULTS: Patients from Heidelberg University Hospital with suspicion of endocarditis, followed by valve replacement and analysis by 16S rDNA PCR, between 2015 and 2018, were evaluated. 146 patients with definite infective endocarditis, confirmed by the valve macroscopics and/or histology, were included. Valve PCRs were compared to corresponding blood and valve culture results. Overall, valve PCR yielded an additional diagnostic benefit in 34 of 146 cases (23%) and was found to be more sensitive than valve culture. In 19 of 38 patients with both negative blood and valve cultures, valve PCR was the only method rendering a pathogen. In 23 patients with positive blood cultures detecting skin commensals, 4 patients showed discordant valve PCR results, detecting a more plausible pathogen, and in 11 of 23 cases, valve PCR confirmed commensals in blood culture as true pathogens. Only the remaining 8 patients had negative valve PCRs. CONCLUSION: Valve PCR was found to be a valuable diagnostic tool in surgical endocarditis cases with negative blood cultures or positive blood cultures of unknown significance. TRIAL REGISTRATION: S-440/2017 on 28.08.2017 retrospectively registered. Subdividing of all infective endocarditis patients in this study, showing that valve PCR yields valuable information for patients with skin commensals in blood cultures, which were either confirmed by the same detection in valve PCR or refuted by the detection of a different and typical pathogen in valve PCR. Additionally, benefit was determined in patients with negative or not available blood cultures and only positive detection in valve PCR. +: Positive; -: negative; n/a: not available results.

RESUMEN

INTRODUCTION: The study's objectives were to improve providers' knowledge of mobile health core competencies; increase providers' knowledge and clinical use of the Virtual Hope Box (VHB) mobile app as an evidence-based treatment tool; and test elements of a structured knowledge translation paradigm. MATERIALS AND METHODS: knowledge translation best practices were integrated into a training workshop with the goal to increase provider adoption of the VHB. Providers were trained at three sites and provided feedback before the training, post-training, and at 3, 6, and 12 months following the training. RESULTS: Pretraining, <22% of respondents indicated that they had used the VHB in clinical practice; post-training, 89% of respondents reported their intent to use the VHB. At 3 and 6 months, 82% of evaluation respondents indicated actual use of the VHB. CONCLUSIONS: Using a public-facing technology, this study successfully integrated knowledge translation methods within an existing provider training program. Implementation planning should be deliberate and consider a target site's capacity for new ideas and potential adoption barriers. Lessons learned have implications for future efforts to bridge the gap between research and practice in improving the quality and impact of clinical care.

RESUMEN

Traditional cultural models typically address factors like ethnicity, language, and race as important concerns pertaining to treatment efficacy, but over the years, professionals have expanded the focus to include gender, sexual orientation, age, socioeconomic status, and other aspects of identity and experience, including military cultural issues. As the integration of mobile health increases in clinical care, another important cultural factor that can impact care is technological culture. Differences in perception of technological competence by patient and provider can impact the provider's ability to effectively connect with the patient and fully leverage tools to support evidence-based treatment. In this article, we describe provider- and patient-level cultural issues in the provision of clinical care in the military and veteran populations and how the development of cultural competency in technological culture can improve patient care. We apply traditional models in the development of cultural competency to technological culture as well as provide recommendations for providers in Department of Defense and Department of Veterans Affairs health care systems that may be relevant to outside clinicians as well. Key factors are addressed when considering the cultural issues involved in the clinical integration of mobile health in the military and veteran populations.

RESUMEN

Mobile applications (apps) to support behavioral health are increasing in number and are recommended frequently by medical providers in a variety of settings. As with the use of any adjunct tool in therapy, psychologists adopting new technologies in clinical practice must comply with relevant professional ethics codes and legal standards. However, emerging technologies can outpace regulations regarding their use, presenting novel ethical considerations. Therefore, it is incumbent upon providers to extrapolate current ethical standards and laws to new technologies before they recommend them as adjuncts to face-to-face treatment. This article identifies best practices for incorporating apps into treatment, including competence in the use of smartphones in general and familiarity with the specific apps recommended. Psychologists must conduct informed consent procedures in accordance with existing evidence, as well as privacy and security concerns relating to a particular app, in order to mitigate potential liability regarding the collection of client-generated data. Psychologists also should be prepared to educate clients about how best to safeguard their data, such as through encryption, password protection, or remote deletion of data. By doing so, psychologists can balance potentially competing demands of leveraging emerging technology to improve care while simultaneously ensuring ethical and legal compliance in these new areas.

RESUMEN

Background: It has been documented that international students face diverse challenges due to language and cultural barriers. International medical students suffer from personal distress, a lack of support and perform poorer than local fellow-students in clinical examinations. It has been documented that international medical students benefit from peer-led tutorials in their first year. We investigated the effectiveness of a tutorial offered for international medical students in their second year. Methods: A peer-guided examination preparation course with interactive elements for second year international medical students was designed, learning objectives were defined. Two evaluations were undertaken: In a quantitative assessment, students were asked to fill out five multiple-choice-questions at the beginning of every session of the tutorial (pre-test) as well as to participate in a post-test at the end of the semester in which all former multiple-choice-questions were re-used. Using a qualitative approach, participants were asked for their thoughts and comments in a semi-structured interview at the end of the semester. Results: International students (N=12) showed significantly better results in the post- than in the pre-test (t(11)=-8.48, p<.001, d=1.95). Within the interviews, international students (N=10) reported to have benefited from technical and didactic, as well as social learning experiences. The individual lectures students were asked to contribute were discussed controversially. Conclusion: Our peer-guided tutorial for second year international medical students is an effective and well accepted possibility to prepare these students for examinations.

RESUMEN

Despite widespread use of the bacille Calmette-Guérin (BCG) vaccine, tuberculosis (TB) remains a leading cause of global mortality from a single infectious agent (Mycobacterium tuberculosis or Mtb). Here, over two independent Mtb challenge studies, we demonstrate that subcutaneous vaccination of rhesus macaques (RMs) with rhesus cytomegalovirus vectors encoding Mtb antigen inserts (hereafter referred to as RhCMV/TB)-which elicit and maintain highly effector-differentiated, circulating and tissue-resident Mtb-specific CD4+ and CD8+ memory T cell responses-can reduce the overall (pulmonary and extrapulmonary) extent of Mtb infection and disease by 68%, as compared to that in unvaccinated controls, after intrabronchial challenge with the Erdman strain of Mtb at ∼1 year after the first vaccination. Fourteen of 34 RhCMV/TB-vaccinated RMs (41%) across both studies showed no TB disease by computed tomography scans or at necropsy after challenge (as compared to 0 of 17 unvaccinated controls), and ten of these RMs were Mtb-culture-negative for all tissues, an exceptional long-term vaccine effect in the RM challenge model with the Erdman strain of Mtb. These results suggest that complete vaccine-mediated immune control of highly pathogenic Mtb is possible if immune effector responses can intercept Mtb infection at its earliest stages.

RESUMEN

BACKGROUND: Therapy with local anesthetics (LAs), also known as neural therapy, is used in integrative medicine because of its anti-inflammatory properties. Ester-linked LAs are often avoided because of their alleged high allergenicity. Little data supports this assumption and hence the importance of our investigation on type-1 allergies against ester- and amide-linked LAs. We performed a prospective, double-blinded, placebo-controlled observational study. METHODS: 177 patients received 340 intracutaneous injections with 1% procaine, 0.5% lidocaine, 1% mepivacaine, or saline solution. Every patient received two different tests on each forearm. Reactions were monitored for 15 minutes. RESULTS: No type-1 allergy was observed. The mean erythema diameter of the wheals after 10 minutes was procaine 8.0 ± 6.4 mm, mepivacaine 7.6 ± 6.3 mm, lidocaine 4.4 ± 4.8 mm, and NaCl 3.7 ± 3.2 mm. The wheal diameter of all substances showed a crescendo-decrescendo phenomenon. The procaine and mepivacaine wheals were significantly larger than those of lidocaine and NaCl. No general signs of hypersensitivity were observed. Diameter and intensity were independent of the injection site, order of injection, age, gender, and body mass index. CONCLUSION: This study shows no higher type-1 allergenicity of the ester-linked LA procaine, compared to the amide-linked LAs lidocaine and mepivacaine, and supports its use in therapy and short-track surgery.

RESUMEN

Randomized controlled trials (RCTs) support the effectiveness of virtual reality exposure therapy (VRET) for anxiety disorders; however, the overall quality of the VRET RCT literature base has yet to be evaluated. This study reviewed 27 VRET RCTs and the degree of adherence to 8 RCT research design criteria derived from existing standards. Adherence to the study quality criteria was generally low as the articles met an average 2.85 criteria (SD=1.56). None of the studies met more than six quality criteria. Study quality did not predict effect size; however, a reduction in effect size magnitude was observed for studies with larger sample sizes when comparing VRET to non-active control groups. VRET may be an effective method of treatment but caution should be exercised in interpreting the existing body of literature supporting VRET relative to existing standards of care. The need for well-designed VRET research is discussed.

RESUMEN

Virtual environments provide the ability to systematically deliver test stimuli in simulated contexts relevant to real world behavior. The current study evaluated the validity of the Virtual Reality Stroop Task (VRST), which presents test stimuli during a virtual reality military convoy with simulated combat threats. Active duty Army personnel (N = 49) took the VRST, a customized version of the Automated Neuropsychological Assessment Metrics (ANAM)-Fourth Edition TBI Battery (2007) that included the addition of the ANAM Stroop and Tower tests, and traditional neuropsychological measures, including the Delis-Kaplan Executive Function System version of the Color-Word Interference Test. Preliminary convergent and discriminant validity was established, and performance on the VRST was significantly associated with computerized and traditional tests of attention and executive functioning. Valid virtual reality cognitive assessments open new lines of inquiry into the impact of environmental stimuli on performance and offer promise for the future of neuropsychological assessments used with military personnel.
