RESUMO

Purpose: Extension for Community Health Outcomes (ECHO) is a model of continuing medical education meant to connect academic medical center-based specialists with community providers to increase capacity in managing complex health conditions. The purpose of this study was to evaluate the effectiveness of a shortened "bootcamp" ECHO model in increasing participant competence with topics related to transgender and gender diverse (TGD) health care and the impact of "bootcamp" participation on enrollment in an ongoing ECHO series. Methods: An ongoing monthly ECHO series was instituted on topics of TGD health. After 2 years, the team implemented a four-session "bootcamp" for four consecutive weeks during March 2022 to introduce foundational topics for new participants who had joined or were considering joining the ongoing series. Qualitative and quantitative results were collected from self-reported pre-/post-surveys as well as from in-session quizzes. Results: There were 71 participants in the "bootcamp" including health care providers and support staff. Attendees reported a 10.3% increase (p = 0.02) in self-reported comfort providing care to transgender patients. Pre-/post-knowledge improved in areas of health inequities (50% vs. 74% correct pre/post), surgical requirements (33% vs. 74%), and effects of masculinizing (55% vs. 70%) and feminizing (64% vs. 89%) hormone therapy. Prescribing providers reported a significant change across four areas of practice competency. Among 71 "bootcamp" participants, 15 registered for the ongoing program. Conclusion: Use of a "bootcamp" highlights ways to increase participant comfort and knowledge in providing TGD health care in a shortened timeframe and recruit new participants to an ongoing ECHO curriculum.

RESUMO

Background: We evaluated the impact of electronic consultation (eConsult) in reducing the environmental pollutants associated with health care delivery. Methods: A retrospective analysis of the eConsult data between July 2018 and December 2022 was extracted from the electronic health record (Epic). Travel time and mileage from the patient home to the academic medical center (AMC) were calculated along with fuel expenditure and greenhouses gas savings. Projected savings through the end of the decade were forecast using a random walk model. Results: A total of 15,499 eConsults were submitted to AMC specialist providers from community primary care providers. Completed eConsults (n = 11,590) eliminated the need for a face-to-face visit with a specialist provider, eliminating mileage, fuel, time, and pollutants associated with face to face visits. In-state travel distance saved was 310,858 miles, travel time saved was 5,491 h, with an associated fuel reduction of 13,575 gallons and $56,893 savings. This reduced greenhouse gas emissions by 128 metric tons of carbon dioxide, 0.022 tons of nitrogen oxide, 0.005 tons of methane, and 0.001 tons of nitrous oxide. Out of state travel distance saved was 188,346 miles with 2,842 h reduced travel time, and associated fuel reduction of 8,225 gallons and of $34,118. Reduced greenhouse gas emissions were equivalent to 77 metric tons of carbon dioxide, 0.0132 tons of nitrogen oxide, 0.0033 tons of methane, and 0.0007 tons of nitrous oxide. Conclusion: This study indicates that medical care provided through telehealth modalities reduces the environmental impact of pollutants associated with face to face visits.

RESUMO

PURPOSE: Evidence supports treatment for opioid use disorder (OUD) with buprenorphine in primary care practices (PCPs). Barriers that slow implementation of this treatment include inadequately trained staff. This study aimed to increase the number of rural PCPs providing OUD treatment with buprenorphine. This evaluation describes the impact of a practice team training on the implementation and delivery of OUD treatment with buprenorphine in PCPs of rural Colorado. METHODS: Implementing Technology and Medication Assisted Treatment Team Training in Rural Colorado (IT MATTTRs) was a multilevel implementation study that included a practice-focused intervention to improve awareness, adoption, and use of buprenorphine treatment for OUD. Participating PCP teams received the IT MATTTRs Practice Team Training and support. Practices' implementation of treatment components was assessed before and after training. Practice-reported and population-level data from the Prescription Drug Monitoring Program were obtained to describe changes in delivery of treatment after training. RESULTS: Forty-two practices received team training. Practices reported an average of 4.7 treatment-related components in place at baseline compared with 13.0 at 12-month follow-up (F[2,56] = 31.17, P <.001). The proportion of participating practices providing or referring patients for treatment increased from 18.8% to 74.4%. The increase in number of people with a prescription for buprenorphine was significantly greater in the study region over a 4-year period compared with the rest of the state (Wald χ2 = 15.73, P <.001). CONCLUSIONS: The IT MATTTRs training for PCP teams in OUD treatment with buprenorphine addressed elements beyond clinician waiver training to make implementation feasible and effectively increased implementation and delivery of this treatment in rural Colorado.

RESUMO

Background: Clinic-to-clinic telemedicine can increase visit frequency in pediatric patients with type 1 diabetes (T1D) living far from a diabetes specialty clinic, but the impact on adoption of diabetes technology is unclear. Materials and Methods: Pediatric patients with T1D in Colorado and surrounding states who received diabetes care using clinic-to-clinic telemedicine were enrolled. Medical records and surveys were reviewed to ascertain technology use, and data were compared to patients from the main clinic population. Results: Patients (N = 128, baseline mean age 12.4 ± 4.2 years, median T1D duration 3.3 years [IQR 1.4-7.7], mean A1c 8.9% ± 1.8%, 60% male, 75% non-Hispanic white, 77% private insurance) who utilized telemedicine were included. Technology use among telemedicine patients was not associated with gender, T1D duration, insurance, distance from the main clinic or rural designation but was associated with ethnicity and A1c. Compared to the main clinic cohort (N = 3636), continuous glucose monitor (CGM) use and pump/CGM combination use was lower among patients participating in clinic-to-clinic telemedicine (CGM: 29.7% vs. 56.0%, P < 0.001; CGM/pump combination: 27.3% vs. 40.3%, P = 0.004). Technology use was associated with lower A1c regardless of cohort. Conclusions: Compared to patients attending in-person clinic, pediatric T1D patients who use clinic-to-clinic telemedicine due to their distance from the main clinic, have lower CGM and combination CGM/pump use. For both telemedicine and main clinic patients, CGM and CGM/pump combination was associated with lower A1c. Additional research is needed to explore reasons for this discrepancy and find methods to improve CGM use in this population.

RESUMO

As the COVID-19 health crisis continues to reshape healthcare, systems across the country face increasing pressure to adapt their models of care to expand access to care, while also improving efficiency and quality in the face of limited resources. Consequently, many have shown a growing interest and receptivity to the expansion of telehealth models to help meet these demands. Electronic consultations (eConsults) are a telehealth modality that allow for a non-face-to-face asynchronous consultation between a primary care provider (PCP) and a specialist aimed at facilitating specialist input without the need for a patient visit. The aim of this case study is to describe eConsults, how they differ from traditional in person models of care and other models of telemedicine and to review the evidence related to the effectiveness of eConsults by PCPs and clinicians from multiple specialties at the University of Colorado School of Medicine. We have worked to develop an infrastructure, delivery system integration, and care model adaptations that aim to improve delivery system performance by ensuring proper care in appropriate settings and lowering costs through reduced utilization. Lastly, we have increased care coordination, improved collaboration and better care transitions through strengthening of relationships between community-based PCPs and academic medical center-based specialists. This work has resulted in cost savings to patients and positive provider satisfaction.

RESUMO

Type I diabetes (T1D) is one of the most common childhood diseases and Type 2 diabetes (T2D) is increasing at alarming rates. Given that children spend a great percentage of their time in school, this setting is a critical environment for models of care that lead to better management of this and other health conditions. The School Nurses Managing Diabetes Care ECHO was offered to Colorado school nurses to build their capacity in providing evidence-based management of T1D. The purpose of this effort was to (1) determine whether or not the model could be used as a tool of collaboration and dissemination for school nurses across Colorado and (2) assess the effectiveness of the "School Nurses Managing Diabetes Care" ECHO learning series. Post-series survey results demonstrated a 25% increase in self-efficacy ratings, moving learners from "average among my peers" toward "competent." Additionally, all respondents planned to make one or more practice changes to improve care for students with T1D. Expanding the use of the ECHO model to implement intensive management of children and youth with T1D is critically important as rates of this and other chronic conditions continue to increase.

RESUMO

INTRODUCTION: Project Extension for Community Health Outcomes (ECHO) was originally developed by the University of New Mexico's Health Science Center (UNMHSC) to build the capacities of primary-care providers and to increase specialty-care access to rural and underserved populations. ECHO Colorado, a replication site at the University of Colorado Anschutz Medical Campus (CUAMC), was developed with the same purpose and to help build the health workforce of Colorado. The CUAMC and its community-based partners recognized that by reducing unnecessary referrals to the medical campus and building primary-care capacity in communities, both would increase their scope and expand overall capacity. This study examines the key factors that influence participant engagement, how participants value the ECHO experience, and the utility of the ECHO Colorado experience according to participants. METHODS: This study used a mixed-methods approach including 42 interviews and 34 completed surveys. Transcribed interview recordings were coded in NVivo 11, and codes were queried in NVivo and Excel to identify key themes. Survey responses were analyzed in SPSS. Data were examined between and across four attendance groups and triangulated to assess the reliability of the data and validity of overall findings. FINDINGS: Key factors increasing registrant engagement included relevant and practical curriculum content; strong and supportive relationships among learners, ECHO faculty, and workplace colleagues; and innovative learning approaches that included opportunities for active, virtual participation through technology, participant management activities, and ECHO's unique curriculum design. CONCLUSION: Findings from this study validated many of the important elements of ECHO Colorado that make it unique from other iterations of the model being implemented nationally and internationally and identified participant-driven strategies for further amplifying its impact.

RESUMO

Introduction: To improve access to care and engage adolescent transplant recipients for adherence-promoting interventions, innovative solutions utilizing technology are needed. Materials and Methods: This study describes the implementation of a five-session group intervention targeting medication adherence in adolescent transplant recipients through home-based telemedicine. Results: Seven videoconferencing groups were conducted with a total of 33 participants living a median of 57 miles away from their transplant medical center. The median coefficient of variation (CV) of tacrolimus (immunosuppression medication) decreased from 32.2% to 23.5% from the pregroup to postgroup phase. Analyses indicated that the group was acceptable and engaging for participants, as highlighted by one participant reporting, "I liked how me and the group members came together… it felt like a little family." Overall satisfaction with the group and with the technology was endorsed by 86%. The group intervention was generally feasible; however, there were technological difficulties reported by participants and the facilitator, particularly given the diversity of the home-based connections and equipment. Other adaptations helped improve recruitment, attendance, and participation. Discussion: Implementing a telehealth group can pose unique challenges, especially with a group of adolescent participants. Although nonsignificant, we observed a decrease in the median CV of tacrolimus, indicating that medication adherence generally improved after group intervention. Our experience facilitating these groups provides insights into strategies to optimize feasibility and the participant experience. Distance of participants from the hospital is an important consideration and provides a strong rationale for the need for telemedicine-enabled approaches. We explore and discuss the challenges to implementing a home-based group, suggest practical strategies and developmentally sensitive adjustments when working with adolescents, and propose strategies to prepare clinicians for obstacles that may present when implementing a telehealth group with youth.

RESUMO

BACKGROUND: Helping Babies Breathe (HBB) is a neonatal resuscitation curriculum that teaches life-saving interventions utilized in the first minutes after birth, reducing morbidity and mortality. Traditionally, it requires in-person facilitators for didactic and hands-on training. OBJECTIVES: The aim of this study was to offer HBB to nurses and nursing students in Guatemala, with the lead facilitator presenting concepts via telehealth and in-person facilitators providing hands-on demonstration. METHODS: Learners completed pre- and post-tests that included the standard HBB knowledge check, as well as an assessment of the course teaching model. Learners also completed the standard Objective Structured Clinical Evaluations (OSCEs). RESULTS: Eighteen learners were included in the analysis. All but one learner (94%) passed the course, and the average percent improvement from the pre- to post-test was 12%. All learners achieved passing scores on the OSCEs. Learners responded positively to questions regarding the technology, connection with the instructor, and ability to ask questions. Ninety-four percent of the learners agreed with the statement "this lecture was as good via telehealth as in person." A cost analysis demonstrated approximately USD 3,979.00 in savings using telehealth compared to a standard in-person course. CONCLUSIONS: The telehealth model was successful in delivering course material to the learners and was well received. This model represents a cost-effective way to improve access to HBB. This study may not be generalizable to other populations, and the ability to use telehealth requires reliable internet connectivity, which may not be available in all settings. Further study and expansion of this pilot are needed to assess success in other settings.

RESUMO

OBJECTIVE: This study evaluated a videoconference-based psychiatric emergency consultation program (telepsychiatry) at geographically dispersed emergency department (ED) sites that are part of the network of care of an academic children's hospital system. The study compared program outcomes with those of usual care involving ambulance transport to the hospital for in-person psychiatric emergency consultation prior to disposition to inpatient care or discharge home. METHODS: This study compared process outcomes in a cross-sectional, pre-post design at five network-of-care sites before and after systemwide implementation of telepsychiatry consultation in 2015. Clinical records on 494 pediatric psychiatric emergencies included ED length of stay, disposition/discharge, and hospital system charges. Satisfaction surveys regarding telepsychiatry consultations were completed by providers and parents or guardians. RESULTS: Compared with children who received usual care, children who received telepsychiatry consultations had significantly shorter median ED lengths of stay (5.5 hours and 8.3 hours, respectively, p<.001) and lower total patient charges ($3,493 and $8,611, p<.001). Providers and patient caregivers reported high satisfaction with overall acceptability, effectiveness, and efficiency of telepsychiatry. No safety concerns were indicated based on readmissions within 72 hours in either treatment condition. CONCLUSIONS: Measured by charges and time, telepsychiatry consultations for pediatric psychiatric emergencies were cost-efficient from a hospital system perspective compared with usual care consisting of ambulance transport for in-person consultation at a children's hospital main campus. Telepsychiatry also improved clinical and operational efficiency and patient and family experience, and it showed promise for increasing access to other specialized health care needs.

RESUMO

BACKGROUND: Young adults with type 1 diabetes (T1D) face many challenges in managing their diabetes, resulting in suboptimal glycemic control and often loss to follow-up. Comprehensive strategies are needed to engage this population in diabetes care and improve outcomes. This pilot study investigated the feasibility and acceptability of the Colorado Young Adults with Type 1 Diabetes (CoYoT1) Clinic-an innovative clinical care model for young adults with T1D, incorporating telemedicine and peer interactions. SUBJECTS AND METHODS: Forty-five patients with T1D, 18-25 years of age, participated in this study. Patients completed one routine, diabetes clinic appointment, using Health Insurance Portability and Accountability-approved, Web-based videoconferencing from a location of their choosing. The clinic visit consisted of an individual appointment with a diabetes provider and a group appointment with other young adults, facilitated by a certified diabetes educator. Patients completed a satisfaction survey and reported the time lost from school or work to complete the virtual appointment compared with time typically lost to complete a traditional, in-person, visit. RESULTS: Patients reported high levels of satisfaction with the virtual clinic and high levels of perceived support from the peer interaction. Additionally, patients reported saving over 6 h from their work or school day when completing their diabetes clinic visit virtually instead of in-person. CONCLUSIONS: In this cross-sectional pilot study, the CoYoT1 Clinic, incorporating Web-based videoconferencing and peer interactions, was feasible and acceptable for young adults with T1D. This model may potentially increase engagement with diabetes care in the young adult population. However, further research is needed to fully evaluate the intervention.

RESUMO

BACKGROUND: The American Diabetes Association (ADA) recommends that children with type 1 diabetes (T1D) see a multidisciplinary team and have hemoglobin A1c (A1C) levels measured every 3 months. Patients in rural areas may not follow guidelines because of limited specialty care access. We hypothesized that videoconferencing would result in equivalent A1C compared with in-person visits and increased compliance with ADA recommendations. MATERIALS AND METHODS: The Barbara Davis Center (BDC) (Aurora, CO) telemedicine program provides diabetes care to pediatric patients in Casper and Cheyenne, WY, via remote consultation with annual in-person visits. Over 27 months, 70 patients were consented, and 54 patients completed 1 year in the study. RESULTS: Patients were 70% male, with a mean age of 12.1 ± 4.1 years and T1D duration of 5.4 ± 4.1 years. There was no significant change between baseline and 1-year A1C levels for patients with data at both time points. Patients saw diabetes specialists an average of 2.0 ± 1.3 times per year in the year prior to starting telemedicine and 2.9 ± 1.3 times (P < 0.0001) in the year after starting telemedicine. Patients and families missed significantly less school and work time to attend appointments. CONCLUSIONS: Our study suggests telemedicine is equivalent to in-person visits to maintain A1C, whereas families increase the number of visits in line with ADA recommendations. Patients and families miss less school and work. Decreased financial burden and increased access may improve overall diabetes care and compliance for rural patients. Further study is needed to detect long-term differences in complications screenings and the financial impact of telemedicine on pediatric diabetes care.

RESUMO

OBJECTIVES: In September 2008, the Texas coast was directly hit by Hurricane Ike. Galveston Island was flooded by 4.25 m of storm surge, affecting most of the island's housing and infrastructure. The purpose of this study is to examine whether youth who did not evacuate (11 percent), and subsequently were exposed to Hurricane Ike, exhibit higher rates of substance use and physical and sexual teen dating violence (TDV; both perpetration and victimization) when compared with adolescents who did evacuate. SETTING: Public high school in southeast Texas that was in the direct path of Hurricane Ike. PARTICIPANTS: An anonymous survey was conducted in March 2009 to 1,048 high school students who returned to the Galveston Island post-storm (41 percent Hispanic, 23 percent African American, and 27 percent White). MAIN OUTCOME MEASURES: Teen dating violence and substance use. RESULTS: Mantel-Haenszel odds ratios, adjusting for age and ethnicity, were computed. When compared with boys who evacuated, nonevacuating boys were more likely to perpetrate physical dating violence and sexual assault and to be a victim of sexual assault. Nonevacuating boys and girls were more likely to report recent use of excessive alcohol, marijuana, and cocaine than those who did evacuate. CONCLUSIONS: School personnel, medical personnel, and mental health service providers should consider screening for evacuation status in seeking to identify those adolescents who most need services after a natural disaster. In addition to addressing internalized emotions and psychological symptoms associated with experiencing trauma, intervention programs should focus on reducing externalized behavior such as substance use and TDV.

RESUMO

Psychological problems are overlooked and undertreated in adolescents, especially in low-income and ethnically-diverse youth. School-based health centers are one way to increase health care utilization, and may be particularly important for accessing hard-to-reach populations. The present study examines adolescents' psychological health and their experiences with receiving needed mental health care. Participants included 1,695 African-American (31%), Hispanic (38%), and White (31%) high-school students in southeast Texas. All students were from the same high school and all had access to a school-based mental health clinic. Twenty six percent of the sample had symptoms indicative of major depression, and 18% had scores consistent with subthreshold depression. Across all ethnicities, the prevalence of depressive symptoms was highest among females. Depressed White students were more likely than depressed minority youth to report having received a prior diagnosis of depression and to have been treated for depression. Thus, ethnic disparities in obtaining needed mental health care may persist even in settings where access to equivalent care is readily available.

RESUMO

An experimental thermal pulse combustor and a differential equation model of this device are shown to exhibit chaotic behavior under certain conditions. Chaos arises in the model by means of a progression of period-doubling bifurcations that occur when operating parameters such as combustor wall temperature or air/fuel flow are adjusted to push the system toward flameout. Bifurcation sequences have not yet been reproduced experimentally, but similarities are demonstrated between the dynamic features of pressure fluctuations in the model and experiment. Correlation dimension, Kolmogorov entropy, and projections of reconstructed attractors using chaotic time series analysis are demonstrated to be useful in classifying dynamical behavior of the experimental combustor and for comparison of test data to the model results. Ways to improve the model are suggested. (c) 1995 American Institute of Physics.
