RESUMO

Objectives: Children and adolescents with medical complexity benefit from care coordination and specialized pediatric care, but many access barriers exist. We implemented a virtual wraparound model to support patients with medical complexity and their families and used an economic framework to measure outcomes. Methods: Children with medical complexity were identified and enrolled in a virtual complex care program with a dedicated multidisciplinary team, which provided care coordination, education, parental support, acute care triage, and virtual visits. A retrospective pre- and postanalysis of data obtained from the Hospital Industry Data Institute (HIDI) database measured inpatient, outpatient, and emergency department (ED) utilization and charges before implementation and during the 2-year program. Results: Eighty (n = 80) children were included in the economic evaluation, and 75 had sufficient data for analysis. Compared to the 12 months before enrollment, patients had a 35.3% reduction in hospitalizations (p = 0.0268), a 43.9% reduction in emergency visits (p = 0.0005), and a 16.9% reduction in overall charges (p = 0.1449). Parents expressed a high degree of satisfaction, with a 70% response rate and 90% satisfaction rate. Conclusions: We implemented a virtual care model to provide in-home support and care coordination for medically complex children and adolescents and used an economic framework to assess changes in utilization and cost. The program had high engagement rates and parent satisfaction, and a pre/postanalysis demonstrated statistically significant reduction in hospitalizations and ED visits for this high-cost population. Further economic evaluation is needed to determine sustainability of this model in a value-based payment system.

RESUMO

Building the next generation of telehealth enabled professionals requires a mixture of team-based, interprofessional practice with novel technologies that connect providers and patients. Effective telehealth education is critical for the development of multidisciplinary training curricula to ensure workforce preparedness. In this study, we evaluated the impact of a formal telehealth education curriculum for interprofessional students through an online elective. Over 12 semesters, 170 students self-selected to enroll in the 3-credit hour interprofessional elective and took part in structured didactic, experiential and interprofessional learning opportunities. Mixed-method assessments show significant knowledge and confidence gains with students reflecting on their roles as future healthcare providers. The results from five years' worth of course data shows not only an opportunity to advance the individual knowledge of trainees, but a larger movement to facilitate changes in practice toward population health goals. Recent global health events have further highlighted the need for a rapid response to public health emergencies by highly trained provider teams who are able to utilize technology as the cornerstone for the continuity of care.

RESUMO

The use of telehealth technology to connect with patients has expanded significantly over the past several years, particularly in response to the global coronavirus disease 2019 pandemic. This technical report describes the present state of telehealth and its current and potential applications. Telehealth has the potential to transform the way care is delivered to pediatric patients, expanding access to pediatric care across geographic distances, leveraging the pediatric workforce for care delivery, and improving disparities in access to care. However, implementation will require significant efforts to address the digital divide to ensure that telehealth does not inadvertently exacerbate inequities in care. The medical home model will continue to evolve to use telehealth to provide high-quality care for children, particularly for children and youth with special health care needs, in accordance with current and evolving quality standards. Research and metric development are critical for the development of evidence-based best practices and policies in these new models of care. Finally, as pediatric care transitions from traditional fee-for-service payment to alternative payment methods, telehealth offers unique opportunities to establish value-based population health models that are financed in a sustainable manner.

RESUMO

Background: The COVID-19 pandemic accelerated the development of telehealth services and thus the need for telehealth education and training to support rapid implementation at scale. A national survey evaluating the current state of the telehealth landscape was deployed to organizational representatives, and included questions related to education and training. Materials and Methods: In the summer of 2020, 71 survey participants (31.8%) completed an online survey seeking to determine the utilization of telehealth services across institutional types and locations. This included data collected to specifically compare the rates and types of formal telehealth education provided before and during the pandemic. Results: Thirty percent of organizations reported no telehealth training before COVID-19, with those in suburban/rural settings significantly less likely to provide any training (55% vs. 82%) compared with urban. Pandemic-related training changes applied to 78% of organizations, with more change happening to those without any training before COVID-19 (95%). Generally, organizations offering training before the pandemic reported deploying COVID-19-related telehealth services, while a higher percentage of those without any training beforehand reported that they either did not plan on providing these services or were in the early planning stages. Discussion: Telehealth education is moving from elective to essential based on the need to prepare and certify the workforce to support high-quality telehealth services. Conclusions: As telehealth continues to evolve to meet the future health care service needs of patients and providers, education and training will advance to meet the needs of everyday clinical encounters and broader public health initiatives.

RESUMO

All children and adolescents deserve access to quality health care regardless of their race/ethnicity, health conditions, financial resources, or geographic location. Despite improvements over the past decades, severe disparities in the availability and access to high-quality health care for children and adolescents continue to exist throughout the United States. Economic and racial factors, geographic maldistribution of primary care pediatricians, and limited availability of pediatric medical subspecialists and pediatric surgical specialists all contribute to inequitable access to pediatric care. Robust, comprehensive telehealth coverage is critical to improving pediatric access and quality of care and services, particularly for under-resourced populations.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic led to an unprecedented demand for health care at a distance, and telehealth (the delivery of patient care using telecommunications technology) became more widespread. Since our 2018 state-of-the-art review assessing the pediatric telehealth landscape, there have been many changes in technology, policy, payment, and physician and patient acceptance of this care model. Clinical best practices in telehealth, on the other hand, have remained unchanged during this time, with the primary difference being the need to implement them at scale.Because of the pandemic, underlying health system weaknesses that have previously challenged telehealth adoption (including inequitable access to care, unsustainable costs in a fee-for-service system, and a lack of quality metrics for novel care delivery modalities) were simultaneously exacerbated. Higher volume use has provided a new appreciation of how patients from underrepresented backgrounds can benefit from or be disadvantaged by the shift toward virtual care. Moving forward, it will be critical to assess which COVID-19 telehealth changes should remain in place or be developed further to ensure children have equitable access to high-quality care.With this review, we aim to (1) depict today's pediatric telehealth practice in an era of digital disruption; (2) describe the people, training, processes, and tools needed for its successful implementation and sustainability; (3) examine health equity implications; and (4) critically review current telehealth policy as well as future policy needs. The American Academy of Pediatrics (AAP) is continuing to develop policy, specific practice tips, training modules, checklists, and other detailed resources, which will be available later in 2021.

RESUMO

Clinical trials are a fundamental tool in evaluating the safety and efficacy of new drugs, medical devices, and health system interventions. Clinical trial visits generally involve eligibility assessment, enrollment, intervention administration, data collection, and follow-up, with many of these steps performed during face-to-face visits between participants and the investigative team. Social distancing, which emerged as one of the mainstay strategies for reducing the spread of SARS-CoV-2, has presented a challenge to the traditional model of clinical trial conduct, causing many research teams to halt all in-person contacts except for life-saving research. Nonetheless, clinical research has continued during the pandemic because study teams adapted quickly, turning to virtual visits and other similar methods to complete critical research activities. The purpose of this special communication is to document this rapid transition to virtual methodologies at Clinical and Translational Science Awards hubs and highlight important considerations for future development. Looking beyond the pandemic, we envision that a hybrid approach, which implements remote activities when feasible but also maintains in-person activities as necessary, will be adopted more widely for clinical trials. There will always be a need for in-person aspects of clinical research, but future study designs will need to incorporate remote capabilities.

RESUMO

Background: Health care is experiencing significant disruptive innovation with the use of technology, including telemedicine and virtual modalities to deliver care. These new models can dramatically improve access to care and reduce health care disparities for patients, especially in underserved and vulnerable populations like children. Problem: To assure diffusions and retention of new approaches they must be assessed for economic value. However, measuring telehealth programs using only an institutional financial viewpoint fails to convey all the societal value of such interventions, so economic studies of telehealth are needed but complex to design. Methods: We reviewed economic study guidelines, details from telehealth study research protocols, IRB submission questions, and telehealth study design literature. We then used an iterative consensus process to develop a framework for measuring value of virtual care at the societal level. Results: The work produced a set of tools that are useful for designing studies for measuring value of virtual care at the societal level. The framework and tools are presented in this report. Conclusions: The conceptual framework for economic evaluation was feasible for use when applied to measure pediatric telehealth value.

RESUMO

BACKGROUND: The American Academy of Pediatrics 2015 policy statement on telehealth proposed that telehealth could increase access to high-quality pediatric care and that pediatricians should work to reduce barriers to telehealth for their patients. However, little is known about pediatricians' experiences with and attitudes toward telehealth. METHODS: Data from a nationally representative survey of American Academy of Pediatrics postresidency US member pediatricians in 2016, restricted to respondents providing direct patient care (n = 744; response rate = 48.7%). Survey collected information on experience with telehealth in the previous 12 months, perceived barriers to telehealth incorporation, and conditions under which nonusers would consider using telehealth. In addition to descriptive statistics, we used multivariable logistic regression to examine characteristics associated with any telehealth experience in the past 12 months. RESULTS: Fifteen percent of pediatricians reported any telehealth use in the 12 months prior to the survey. The most commonly reported barriers to telehealth adoption were insufficient payment and billing issues. Multivariable regression models indicated that pediatricians in rural areas, the West, and subspecialists were most likely to report telehealth use, and identifying barriers was negatively associated with telehealth use. Among nonusers, over half indicated they would consider adopting telehealth if they were paid for the visits. CONCLUSION: Telehealth is considered an important health care delivery mechanism, but only 15% of pediatricians in 2016 reported having used telehealth. Reducing barriers will be instrumental in promoting future telehealth adoption. Many barriers have been reduced during the response to COVID-19, and the impact of these policy changes will need further study.

RESUMO

Background: The Telehealth Dissemination Forum brought together a cross section of telehealth providers and constituents to review the latest telehealth research funded by Patient-Centered Outcomes Research Institute (PCORI) and to ascertain whether there were known gaps in the research. Methods: A pre- and postsurvey was conducted before and after the general overview of the market and research presentations. Using elements of human-centered design, participants were exposed to alternative problem solving and program design methods with the goal of translating the research into practice. Participants were stratified into four groups each with a moderator. Designers instructed the group throughout the design session. Results: A debrief was conducted at the end of the day to determine the value of the session as written evaluations were often not completed or less constructive. Postmeeting surveys were analyzed. Conclusions: We determined that the dissemination was effective; knowledge, attitudes, practices, and beliefs changed based on how this information was presented. The forum had an impact on participants as they left with design tools to assist with complex problem solving.

RESUMO

The growth and evolution of telehealth are opening new avenues for efficient, effective, and affordable pediatric health care services in the United States and around the world. However, there remain several barriers to the integration of telehealth into current practice. Establishing the necessary technical, administrative, and operational infrastructure can be challenging, and there is a relative lack of rigorous research data to demonstrate that telehealth is indeed delivering on its promise. That being said, a knowledge of the current state of pediatric telehealth can overcome many of these barriers, and programs are beginning to collaborate through a new pediatric telehealth research network called Supporting Pediatric Research on Outcomes and Utilization of Telehealth (SPROUT). In this report, we provide an update on the landscape of pediatric telehealth and summarize the findings of a recent SPROUT study in which researchers assessed pediatric telehealth programs across the United States. There were >50 programs representing 30 states that provided data on their implementation barriers, staffing resources, operational processes, technology, and funding sources to establish a base understanding of pediatric telehealth infrastructure on a national level. Moving forward, the database created from the SPROUT study will also serve as a foundation on which multicenter studies will be developed and facilitated in an ongoing effort to firmly establish the value of telehealth in pediatric health care.

RESUMO

OBJECTIVE: To examine the relationship between pediatric critical care telemedicine consultation to rural emergency departments and triage decisions. We compare the triage location and provider rating of the accuracy of remote assessment for a cohort of patients who receive critical care telemedicine consultations and a similar group of patients receiving telephone consultations. DESIGN: Retrospective evaluation of consultations occurring between April 2012 and March 2016. SETTING: Pediatric critical care telemedicine and telephone consultations in 52 rural healthcare settings in South Carolina. PATIENTS: Pediatric patients receiving critical care telemedicine or telephone consultations. INTERVENTION: Telemedicine consultations. MEASUREMENTS AND MAIN RESULTS: Data were collected from the consulting provider for 484 total consultations by telephone or telemedicine. We examined the providers' self-reported assessments about the consultation, decision-making, and triage outcomes. We estimate a logit model to predict triage location as a function of telemedicine consult age and sex. For telemedicine patients, the odds of triage to a non-ICU level of care are 2.55 times larger than the odds for patients receiving telephone consultations (p = 0.0005). Providers rated the accuracy of their assessments higher when consultations were provided via telemedicine. When patients were transferred to a non-ICU location following a telemedicine consultation, providers indicated that the use of telemedicine influenced the triage decision in 95.7% of cases (p < 0.001). For patients transferred to a non-ICU location, an increase in transfers to a higher level of care within 24 hours was not observed. CONCLUSION: Pediatric critical care telemedicine consultation to community hospitals is feasible and results in a reduction in PICU admissions. This study demonstrates an improvement in provider-reported accuracy of patient assessment via telemedicine compared with telephone, which may produce a higher comfort level with transporting patients to a lower level of care. Pediatric critical care telemedicine consultations represent a promising means of improving care and reducing costs for critically ill children in rural areas.

RESUMO

Telemedicine is by no means a new technology, given that audio-video telecommunication links have been utilized for the provision of medical services since the 1950s. Nonetheless, telemedicine is currently in a phase of rapid growth and evolution. The combination of increasingly affordable and powerful networking, computing, and communication technology, along with the continued nationwide crisis in health care access and costs, has created a "tipping point," whereby telemedicine has progressed from a novel means of practicing medicine to practical tool to help address our nation's health care needs. Telemedicine has also evolved beyond a means of providing care to remote communities to becoming a versatile tool in the delivery of health care in a variety of non-rural settings. Although no one can be everywhere at once, telemedicine allows us to be in more places at once than we've ever been before. The problems of disparities and access to care are even more evident in pediatrics, where subspecialists are fewer in number and more regionalized than adult providers. Numerous successful telemedicine programs across the country have demonstrated the impact that these technologies can have in pediatrics, with many more programs in development. As a versatile means of delivering care, telemedicine can be used at any point during the course of a health care encounter as not only a means of expanding our reach, but also as a means of increasing efficiency. Using telemedicine to provide consultations to community hospitals has been shown to improve quality of care, strengthen the referral base for the consulting facilities, facilitate cost savings, and improve the financial bottom line for both referring and consulting facilities. This review highlights some of the ways in which telemedicine is being used to facilitate timely and effective pediatric care in a variety of hospital settings.

RESUMO

The timber rattlesnake, also known as Crotalus horridus, is well known to cause significant injury from toxins stored within its venom. During envenomation, toxic systemic effects immediately begin to cause damage to many organ systems including cardiovascular, hematologic, musculoskeletal, respiratory, and neurologic. One defining characteristic of the timber rattlesnake is a specific neurotoxin called crotoxin, or the "canebrake toxin," which is a potent ß-neurotoxin affecting presynaptic nerves that can cause paralysis by inhibiting appropriate neuromuscular transmission. We present an unusual case of an 8-year-old boy bitten twice on his calf by a timber rattlesnake, who presented with a life-threatening envenomation and suffered multisystem organ failure as well as a prominent presynaptic neurotoxicity resulting in facial diplegia, pharyngeal paralysis, and ophthalmoplegia.

RESUMO

BACKGROUND/PURPOSE: The aim of this study was to review evidence-based literature addressing pertinent questions about venous thromboembolism (VTE) after traumatic injury in children. METHODS: Data were obtained from English-language articles identified through Pubmed published from 1995 until November 2012, and from bibliographies of relevant articles. Studies were included if they contributed evidence to one of the following questions. In the pediatric traumatic injury population: (1) What is the overall incidence of VTE? (2) Is age (adolescence versus pre-adolescence) associated with higher VTE incidence? (3) Which risk factors are associated with higher VTE incidence? (4) Does mechanical and/or pharmacological prophylaxis impact outcomes? RESULTS: Eighteen articles were included in this systematic review. The evidence regarding each question was evaluated, graded by author consensus, and summarized. CONCLUSIONS: The overall incidence of VTE is low. Older (>13years) and more severely injured patients are at higher VTE risk. Additional factors including injury type or presence of a central venous catheter also place a patient at higher VTE risk. Implementation of a risk-based clinical practice guideline for VTE prophylaxis has been associated with reduced symptomatic VTE at one institution. Randomized, prospective trials analyzing outcomes of VTE prophylaxis in pediatric trauma victims are needed.

RESUMO

BACKGROUND: End-tidal carbon dioxide (P(ETCO(2))) is a surrogate, noninvasive measurement of arterial carbon dioxide (P(aCO(2))), but the clinical applicability of P(ETCO(2)) in the intensive care unit remains unclear. Available research on the relationship between P(ETCO(2)) and P(aCO(2)) has not taken a detailed assessment of physiologic dead space into consideration. We hypothesized that P(ETCO(2)) would reliably predict P(aCO(2)) across all levels of physiologic dead space, provided that the expected P(ETCO(2))-P(aCO(2)) difference is considered. METHODS: Fifty-six mechanically ventilated pediatric patients (0-17 y old, mean weight 19.5 +/- 24.5 kg) were monitored with volumetric capnography. For every arterial blood gas measurement during routine care, we measured P(ETCO(2)) and calculated the ratio of dead space to tidal volume (V(D)/V(T)). We assessed the P(ETCO(2))-P(aCO(2)) relationship with Pearson's correlation coefficient, in 4 V(D)/V(T) ranges. RESULTS: V(D)/V(T) was 0.7 for 54 measurements (11%). The correlation coefficients between P(ETCO(2)) and P(aCO(2)) were 0.95 (mean difference 0.3 +/- 2.1 mm Hg) for V(D)/V(T) 0.7. CONCLUSIONS: There were strong correlations between P(ETCO(2)) and P(aCO(2)) in all the V(D)/V(T) ranges. The P(ETCO(2))-P(aCO(2)) difference increased predictably with increasing V(D)/V(T).
