Shifting practice in pediatric prescription opioid use in the emergency department for fractures.

OBJECTIVES: Judicious opioid use is important for balancing patient comfort and safety. Although opioid use is well studied in adult populations, pediatric opioid prescription practices are less understood and there are very few guidelines regarding its usage. The purpose of this study was to investigate pediatric opioid prescription trends by emergency medicine physicians over the last ten years, including assessing proxies for the adequacy of pain control and risk of any opioid-related adverse events including overdose. METHODS: A retrospective analysis was performed of all patients age 0 to 18 who presented to an urban county hospital emergency department (ED) between 2007 and 2017 for acute fracture care. Data collected included age, opioids given in the ED, opioid prescriptions from the ED, adverse events, and secondary opioid prescriptions. Opioid prescription quantities were assessed in morphine equivalents (Meqs). RESULTS: Out of 4713 patients diagnosed with acute fracture, opioid prescriptions from the ED were given to 1772 patients (37.6%), with a mean quantity of 107.0 Meqs (SD = 69.1). Over the ten-year period studied, prescription rates declined from 54.8% in 2007 to 13.6% in 2017. Although 201 (4.3%) fracture patients had a second fracture-related ED visit, only 27 visits (0.57%) were for inadequate pain control, with no significant differences in year-to-year analysis. During the ten-year study period, there were zero opioid overdoses reported among pediatric fracture patients. CONCLUSIONS: A major shift has occurred in the last ten years, as emergency medicine physicians now favor non-opioid pain management regimens over opioids for the majority of pediatric fracture patients. There was no increase in the rate of inadequate pain control requiring a return to the ED, even as opioid prescription rates declined during the study period.

Early Patient-Centered Outcomes Research Experience With the Use of Telehealth to Address Disparities: Scoping Review.

BACKGROUND: Health systems and providers across America are increasingly employing telehealth technologies to better serve medically underserved low-income, minority, and rural populations at the highest risk for health disparities. The Patient-Centered Outcomes Research Institute (PCORI) has invested US $386 million in comparative effectiveness research in telehealth, yet little is known about the key early lessons garnered from this research regarding the best practices in using telehealth to address disparities. OBJECTIVE: This paper describes preliminary lessons from the body of research using study findings and case studies drawn from PCORI seminal patient-centered outcomes research (PCOR) initiatives. The primary purpose was to identify common barriers and facilitators to implementing telehealth technologies in populations at risk for disparities. METHODS: A systematic scoping review of telehealth studies addressing disparities was performed. It was guided by the Arksey and O'Malley Scoping Review Framework and focused on PCORI's active portfolio of telehealth studies and key PCOR identified by study investigators. We drew on this broad literature using illustrative examples from early PCOR experience and published literature to assess barriers and facilitators to implementing telehealth in populations at risk for disparities, using the active implementation framework to extract data. Major themes regarding how telehealth interventions can overcome barriers to telehealth adoption and implementation were identified through this review using an iterative Delphi process to achieve consensus among the PCORI investigators participating in the study. RESULTS: PCORI has funded 89 comparative effectiveness studies in telehealth, of which 41 assessed the use of telehealth to improve outcomes for populations at risk for health disparities. These 41 studies employed various overlapping modalities including mobile devices (29/41, 71%), web-based interventions (30/41, 73%), real-time videoconferencing (15/41, 37%), remote patient monitoring (8/41, 20%), and store-and-forward (ie, asynchronous electronic transmission) interventions (4/41, 10%). The studies targeted one or more of PCORI's priority populations, including racial and ethnic minorities (31/41, 41%), people living in rural areas, and those with low income/low socioeconomic status, low health literacy, or disabilities. Major themes identified across these studies included the importance of patient-centered design, cultural tailoring of telehealth solutions, delivering telehealth through trusted intermediaries, partnering with payers to expand telehealth reimbursement, and ensuring confidential sharing of private information. CONCLUSIONS: Early PCOR evidence suggests that the most effective health system- and provider-level telehealth implementation solutions to address disparities employ patient-centered and culturally tailored telehealth solutions whose development is actively guided by the patients themselves to meet the needs of specific communities and populations. Further, this evidence shows that the best practices in telehealth implementation include delivery of telehealth through trusted intermediaries, close partnership with payers to facilitate reimbursement and sustainability, and safeguards to ensure patient-guided confidential sharing of personal health information.

Temporal Dynamics of Collaborative Networks in Large Scientific Consortia.

The emergence of collective creative enterprise such as large scientific consortia is a unique feature in modern scientific research. We analyzed the temporal co-authorship network structures of ENCODE and modENCODE consortia. Our analysis revealed that the consortium members work closely as a community whereas non-members collaborate in the scale of a few laboratories. We also identified a few brokers playing an important role to facilitate collaborations with outside researchers.

Enzyme-Free Nucleic Acid Amplification Assay Using a Cellphone-Based Well Plate Fluorescence Reader.

Nucleic acids, DNA and RNA, provide important fingerprint information for various pathogens and have significant diagnostic value; however, improved approaches are urgently needed to enable rapid detection of nucleic acids in simple point-of-care formats with high sensitivity and specificity. Here, we present a system that utilizes a series of toehold-triggered hybridization/displacement reactions that are designed to convert a given amount of RNA molecules (i.e., the analyte) into an amplified amount of signaling molecules without any washing steps or thermocycling. Fluorescent probes for signal generation were designed to consume products of the catalytic reaction in order to push the equilibrium and enhance the assay fold amplification for improved sensitivity and reaction speed. The system of toehold-assisted reactions is also modeled to better understand its performance and capabilities, and we empirically demonstrate the success of this approach with two analytes of diagnostic importance, i.e., influenza viral RNA and a micro RNA (miR-31). We also show that the amplified signal permits using a compact and cost-effective smartphone-based fluorescence reader, an important requirement toward a nucleic-acid-based point-of-care diagnostic system.

Insight into NSCLC through novel analysis of gene interactions and characteristics.

Around 80 to 85% of all lung cancers are non-small cell lung cancer (NSCLC). Previous research has aimed at exploring the genetic basis of NSCLC through individual approaches, but studies have yet to investigate the results of combining them. Here we show that analyzing NSCLC genetics through three approaches simultaneously creates unique insights into our understanding of the disease. Through a combination of previous research and bioinformatics tools, we determined 35 NSCLC candidate genes. We analyzed these genes in 3 different approaches. First, we found the gene fusions between these candidate genes. Second, we found the common superfamilies between genes. Finally, we identified mutational signatures that are possibly associated with NSCLC. Each approach has its individual, unique results. Fusion relationships identify specific gene fusion targets, common superfamilies identify possible avenues to determine novel target genes, and identifying NSCLC associated mutational signatures has diagnostic and prognostic benefits. Combining the approaches, we found that gene CD74 has significant fusion relationships, but it has no association with the other two approaches, suggesting that CD74 is associated with NSCLC mainly because of its fusion relationships. Targeting the gene fusions of CD74 may be an alternative NSCLC treatment. This genetic analysis has indeed created unique insight into NSCLC genes. Both the results from each of the approaches separately and combined allow pursuit of more effective treatment strategies for this cancer. The methodology presented can also apply to other cancers, creating insights that current analytical methods could not find.

Adverse Childhood Experiences (ACEs) in Unhoused Children Increase Odds of Psychiatric Illness, Physical Illness, and Psychiatric Admission.

Unhoused children and adolescents have high rates of adverse childhood experiences (ACEs). The objective of this study was to characterize a large cohort of unhoused children and investigate rates of psychiatric diagnoses, medical diagnoses, and utilization of emergency department (ED) resources depending on the presence of additional documented ACEs. A retrospective cohort of all unhoused children who presented to the ED of a large Midwestern health system from January 2014 to July 2019 were included. Unhoused status was determined by address field or ICD-10 code for homelessness (Z59.0). Demographics and ED visits were extracted from the electronic health record. Past medical history, ACEs, chief complaint (CC), length of stay (LOS), imaging, and labs were extracted by chart review. T-tests, chi square tests, and Fisher's exact tests were completed for each sub-analysis. Unhoused children with at least one additional ACE had higher odds of the following psychiatric disorders: depression (OR = 5.2, 95% CI = 3.4- 7.9), anxiety (OR = 3.4, 95% CI = 32.1-5.5), behavioral disorder (OR = 7.2, 95% CI = 35.1- 10.4), psychoses (OR = 6.0, 1.9-18.4), bipolar disorder (OR = 19.8, 95% CI = 34.6-84.9), suicidal ideation (OR = 8.0, 95% CI = 34.8-13.4), post-traumatic stress disorder (OR = 10.1, 95% CI = 35.4-18.6), and attention deficit hyperactive disorder (OR = 4.1, 3.0-5.7). Patients with additional documented ACEs were also more likely to have a prior psychiatric admission (p < 0.001). Unhoused children and adolescents with exposure to additional documented ACEs are more likely to have some serious psychiatric and medical diagnoses compared to other unhoused children.

Prevalence and Homology of the Pneumococcal Serine-Rich Repeat Protein at the Global Scale.

Pneumococcal pneumonia remains a WHO high-priority disease despite multivalent conjugate vaccines administered in clinical practice worldwide. A protein-based, serotype-independent vaccine has long-promised comprehensive coverage of most clinical isolates of the pneumococcus. Along with numerous pneumococcal surface protein immunogens, the pneumococcal serine-rich repeat protein (PsrP) has been investigated as a potential vaccine target due to its surface exposure and functions toward bacterial virulence and lung infection. Three critical criteria for its vaccine potential - the clinical prevalence, serotype distribution, and sequence homology of PsrP - have yet to be well characterized. Here, we used genomes of 13,454 clinically isolated pneumococci from the Global Pneumococcal Sequencing project to investigate PsrP presence among isolates, distribution among serotypes, and interrogate its homology as a protein across species. These isolates represent all age groups, countries worldwide, and types of pneumococcal infection. We found PsrP present in at least 50% of all isolates across all determined serotypes and nontypeable (NT) clinical isolates. Using a combination of peptide matching and HMM profiles built on full-length and individual PsrP domains, we identified novel variants that expand PsrP diversity and prevalence. We also observed sequence variability in its basic region (BR) between isolates and serotypes. PsrP has a strong vaccine potential due to its breadth of coverage, especially in nonvaccine serotypes (NVTs) when exploiting its regions of conservation in vaccine design. IMPORTANCE An updated outlook on PsrP prevalence and serotype distribution sheds new light on the comprehensiveness of a PsrP-based protein vaccine. The protein is present in all vaccine serotypes and highly present in the next wave of potentially disease-causing serotypes not included in the current multivalent conjugate vaccines. Furthermore, PsrP is strongly correlated with clinical isolates harboring pneumococcal disease as opposed to pneumococcal carriage. PsrP is also highly present in strains and serotypes from Africa, where the need for a protein-based vaccine is the greatest, giving new reasoning to pursue PsrP as a protein vaccine.

Antemortem Health System Utilization in People Experiencing Homelessness Who Died in the Emergency Department.

People experiencing homelessness (PEH) have high rates of mortality, medical and psychiatric comorbidities, and emergency department utilization. In this study, a health system's emergency department encounters were evaluated to identify PEH who died in the emergency department. Patient demographics, medical history, prehospital and emergency department characteristics, and health care utilization patterns were collected. Descriptive statistics were calculated. We identified 48 PEH pronounced dead in the emergency department; mean age at death was 46.5. Forty-four (92%) decedents presented in cardiac arrest, 12 (25%) of which were substance use-related; 4 (8%) presented with trauma. Out of 44 patients presenting in cardiac arrest, (20.5%) had bystander cardiopulmonary resuscitation (CPR) performed before arrival of emergency medical services. In the year prior to death, 15 (32%) decedents had no documented health care utilization, while 16 (33%) had 10 or more emergency department/outpatient visits. Our study is the first to characterize PEH who died in the emergency department, analyzing the pre-hospital and in-hospital characteristics and antemortem health system utilization in this population. A sizeable proportion of deceased PEH had no health system contact in the 12 months prior to death, suggesting that those with high mortality risk may underutilize health services. Conversely, a similar proportion of decedents had extensive (more than 10) health system utilization in the year prior to death, representing possible opportunities to reduce mortality.

Playing in the clinical decision support sandbox: tools and training for all.

Objectives: Introduce the CDS-Sandbox, a cloud-based virtual machine created to facilitate Clinical Decision Support (CDS) developers and implementers in the use of FHIR- and CQL-based open-source tools and technologies for building and testing CDS artifacts. Materials and Methods: The CDS-Sandbox includes components that enable workflows for authoring and testing CDS artifacts. Two workshops at the 2020 and 2021 AMIA Annual Symposia were conducted to demonstrate the use of the open-source CDS tools. Results: The CDS-Sandbox successfully integrated the use of open-source CDS tools. Both workshops were well attended. Participants demonstrated use and understanding of the workshop materials and provided positive feedback after the workshops. Discussion: The CDS-Sandbox and publicly available tutorial materials facilitated an understanding of the leading-edge open-source CDS infrastructure components. Conclusion: The CDS-Sandbox supports integrated use of the key CDS open-source tools that may be used to introduce CDS concepts and practice to the clinical informatics community.

Treatment of Misophonia with Risperidone in a Patient with Autism Spectrum Disorder.

We report the case of a 32-year-old male with autism spectrum disorder (ASD) suffering from severe misophonia. After titrating risperidone to 2 mg twice a day, the patient reported a significant reduction in his symptoms and his Amsterdam misophonia scale-revised (AMISOS-R) score dropped by from 31 to 5. Upon discharge, the patient was noted to have decreased irritability and overall improved behavior and effect. This significant symptomatic improvement was likely not explained by inpatient admission alone or other simultaneous pharmacologic treatments, as the effect was seen during an isolated titration of risperidone with other treatments remaining constant. Although, unfortunately, follow-up findings indicated that the treatment was not curative for the patient, risperidone's potential for treating misophonia may warrant systematic investigation.

Selecting venues for AMIA events and conferences: guiding ethical principles.

A discussion and debate on the American Medical Informatics Association's (AMIA) Ethical, Legal, and Social Issues (ELSI) Working Group listserv in 2021 raised important issues related to a forthcoming conference in Texas. Texas had recently enacted a restrictive abortion law and restricted voting rights. Several AMIA members advocated for a boycott of the state and the scheduled conference. The discussion led the AMIA Board of Directors to request that the organization's Ethics Committee provide general guidance for principle-based venue selection. This document recommends overarching principles for the venue selection for future AMIA events and conferences. Discussions by the AMIA Board, the Ethics Committee, and the ELSI Working Group informed these recommendations, and this document on guiding principles was approved by the AMIA Board of Directors in April 2022.

Ethics and informatics in the age of COVID-19: challenges and recommendations for public health organization and public policy.

The COVID-19 pandemic response in the United States has exposed significant gaps in information systems and processes that prevent timely clinical and public health decision-making. Specifically, the use of informatics to mitigate the spread of SARS-CoV-2, support COVID-19 care delivery, and accelerate knowledge discovery bring to the forefront issues of privacy, surveillance, limits of state powers, and interoperability between public health and clinical information systems. Using a consensus-building process, we critically analyze informatics-related ethical issues in light of the pandemic across 3 themes: (1) public health reporting and data sharing, (2) contact tracing and tracking, and (3) clinical scoring tools for critical care. We provide context and rationale for ethical considerations and recommendations that are actionable during the pandemic and conclude with recommendations calling for longer-term, broader change (beyond the pandemic) for public health organization and policy reform.

Evaluating visual analytics for health informatics applications: a systematic review from the American Medical Informatics Association Visual Analytics Working Group Task Force on Evaluation.

OBJECTIVE: This article reports results from a systematic literature review related to the evaluation of data visualizations and visual analytics technologies within the health informatics domain. The review aims to (1) characterize the variety of evaluation methods used within the health informatics community and (2) identify best practices. METHODS: A systematic literature review was conducted following PRISMA guidelines. PubMed searches were conducted in February 2017 using search terms representing key concepts of interest: health care settings, visualization, and evaluation. References were also screened for eligibility. Data were extracted from included studies and analyzed using a PICOS framework: Participants, Interventions, Comparators, Outcomes, and Study Design. RESULTS: After screening, 76 publications met the review criteria. Publications varied across all PICOS dimensions. The most common audience was healthcare providers (n = 43), and the most common data gathering methods were direct observation (n = 30) and surveys (n = 27). About half of the publications focused on static, concentrated views of data with visuals (n = 36). Evaluations were heterogeneous regarding setting and measurements used. DISCUSSION: When evaluating data visualizations and visual analytics technologies, a variety of approaches have been used. Usability measures were used most often in early (prototype) implementations, whereas clinical outcomes were most common in evaluations of operationally-deployed systems. These findings suggest opportunities for both (1) expanding evaluation practices, and (2) innovation with respect to evaluation methods for data visualizations and visual analytics technologies across health settings. CONCLUSION: Evaluation approaches are varied. New studies should adopt commonly reported metrics, context-appropriate study designs, and phased evaluation strategies.

The value of provider-to-provider telehealth.

Telehealth has great potential to improve access to care, but its adoption in routine healthcare has been slow. The lack of clarity about the value of telehealth implementations has been one reason cited for this slow adoption. The Center for Information Technology Leadership has examined the value of telehealth encounters in which there is a provider both with the patient and at a distance from the patient. We considered three models of telehealth: store-and-forward, real-time video, and hybrid systems. Evidence from the literature was extrapolated using a computer simulation, which found that the hybrid model was the most cost effective. The simulation predicted savings of $4.3 billion per year if hybrid telehealth systems were implemented in emergency rooms, prisons, nursing home facilities, and physician offices across the United States. We also conducted a sensitivity analysis to determine which factors most influence costs and savings. Payers, providers, and policymakers should work together to remove the barriers to the adoption of telehealth so that this cost savings can be realized in the U.S. healthcare system.

The value proposition in the widespread use of telehealth.

Telehealth has great potential to improve access to care but its adoption in routine health care has been slow. The lack of clarity about the value of telehealth implementations has been one reason cited for this slow adoption. The Center for Information Technology Leadership has examined the value of telehealth encounters in which there is a provider both with the patient and at a distance from the patient. We considered three models of telehealth: store-and-forward, real-time video and hybrid systems. Evidence from the literature was extrapolated using a simulation, which found that the hybrid model was the most cost-effective of the three. The simulation predicted savings of $4.3 billion per year if hybrid telehealth systems were to be implemented in emergency rooms, prisons, nursing home facilities and physician offices across the US. We also conducted a sensitivity analysis to determine which factors most affected costs and savings. For all three telehealth models, the highest sensitivities were to the cost of a face-to-face visit, the cost of a telehealth visit and the success rate of a telehealth visit, i.e. the proportion of telehealth visits that avoided the need for a face-to-face visit. Payers, providers and policy-makers should work together to remove the barriers to the adoption of telehealth in order to make it widely available to all.

Enhanced Recovery via Peripheral Nerve Block for Open Hepatectomy.

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols are now commonplace in many fields of surgery, but only limited data exists for their use in hepatobiliary surgery. We implemented standardized ERAS protocols for all open hepatectomies and replaced thoracic epidurals with a transversus abdominis plane (TAP) block. METHODS: We performed a retrospective cohort study of all patients undergoing open hepatectomy during the 14 months before and 19 months after implementation of an ERAS protocol at our institution (January 2014-September 2016). Trained abstractors reviewed charts for patient demographics, perioperative details, and healthcare utilization. All nursing-reported visual analog scale pain scores were sampled to identify patients with uncontrolled pain (daily mean score > 5). Outcomes included length of stay (LOS), costs, and 30-day readmission. RESULTS: A total of 127 patients (mean age 54.6 ± 13.0 years, 44% female) underwent open liver resection (69 [54%] after ERAS implementation). ERAS protocols were associated with significantly lower rates of ICU admission (47 vs. 13%, p < 0.001), shorter LOS (median 5.3 vs. 4.3 days, p = 0.007), and lower median costs ($3566 less, p = 0.03). Readmission remained low throughout the study period (5% pre-ERAS, 4% during ERAS, p = 0.83). Rates of uncontrolled pain were either the same or better after ERAS implementation through post-operative day #3 (41% pre-ERAS, 23% during ERAS, p = 0.03). DISCUSSION: The use of TAP block for hepatectomy as part of an ERAS protocol is associated with improved quality and cost of care. Surgeons performing liver resections should consider standardization of evidence-based best practices in all patients.

Crossing the evidence chasm: building evidence bridges from process changes to clinical outcomes.

OBJECTIVE: Although demand for information about the effectiveness and efficiency of health care information technology grows, large-scale resource-intensive randomized controlled trials of health care information technology remain impractical. New methods are needed to translate more commonly available clinical process measures into potential impact on clinical outcomes. DESIGN: The authors propose a method for building mathematical models based on published evidence that provides an evidence bridge between process changes and resulting clinical outcomes. This method combines tools from systematic review, influence diagramming, and health care simulations. MEASUREMENTS: The authors apply this method to create an evidence bridge between retinopathy screening rates and incidence of blindness in diabetic patients. RESULTS: The resulting model uses changes in eye examination rates and other evidence-based population parameters to generate clinical outcomes and costs in a Markov model. CONCLUSION: This method may serve as an alternative to more expensive study designs and provide useful estimates of the impact of health care information technology on clinical outcomes through changes in clinical process measures.

The cost of information technology-enabled diabetes management.

As a result of the high cost of diabetes, an array of interventions for managing this disease has been developed. Estimating the cost of various approaches to diabetes disease management is critical to inform purchasing decisions. This review focuses on 5 provider- and payer-sponsored diabetes management approaches that use information technology (IT) and provides cost estimates for each approach based on a literature review and interviews with 38 provider practices, hospitals, payers, and vendors. Cost estimates are reported for "typical" small, medium, and large provider practices and payers. Provider-sponsored diabetes registries are estimated to be the least expensive approach for small and medium sized practices. For large practices with electronic health record systems, modifying such systems with diabetes-specific clinical decision support capabilities is projected to be the most economical approach. While limited data prevented the inclusion of all implementation costs, these projections serve as a starting point to inform the purchasing decisions of organizations planning to introduce IT-enabled diabetes management.

The economic benefits of health information exchange interoperability for Australia.

OBJECTIVE: To estimate costs and benefits for Australia of implementing health information exchange interoperability among health care providers and other health care stakeholders. DESIGN: A cost-benefit model considering four levels of interoperability (Level 1, paper based; Level 2, machine transportable; Level 3, machine readable; and Level 4, machine interpretable) was developed for Government-funded health services, then validated by expert review. RESULTS: Roll-out costs for Level 3 and Level 4 interoperability were projected to be $21.5 billion and $14.2 billion, respectively, and steady-state costs, $1470 million and $933 million per annum, respectively. Level 3 interoperability would achieve steady-state savings of $1820 million, and Level 4 interoperability, $2990 million, comprising transactions of: laboratory $1180 million (39%); other providers, $893 million (30%); imaging centre, $680 million (23%); pharmacy, $213 million (7%) and public health, $27 million (1%). Net steady-state Level 4 benefits are projected to be $2050 million: $1710 million more than Level 3 benefits of $348 million, reflecting reduced interface costs for Level 4 interoperability due to standardisation of the semantic content of Level 4 messages. CONCLUSIONS: Benefits to both providers and society will accrue from the implementation of interoperability. Standards are needed for the semantic content of clinical messages, in addition to message exchange standards, for the full benefits of interoperability to be realised. An Australian Government policy position supporting such standards is recommended.

Highly Stable and Sensitive Nucleic Acid Amplification and Cell-Phone-Based Readout.

Key challenges with point-of-care (POC) nucleic acid tests include achieving a low-cost, portable form factor, and stable readout, while also retaining the same robust standards of benchtop lab-based tests. We addressed two crucial aspects of this problem, identifying a chemical additive, hydroxynaphthol blue, that both stabilizes and significantly enhances intercalator-based fluorescence readout of nucleic acid concentration, and developing a cost-effective fiber-optic bundle-based fluorescence microplate reader integrated onto a mobile phone. Using loop-mediated isothermal amplification on lambda DNA we achieve a 69-fold increase in signal above background, 20-fold higher than the gold standard, yielding an overall limit of detection of 25 copies/µL within an hour using our mobile-phone-based platform. Critical for a point-of-care system, we achieve a >60% increase in fluorescence stability as a function of temperature and time, obviating the need for manual baseline correction or secondary calibration dyes. This field-portable and cost-effective mobile-phone-based nucleic acid amplification and readout platform is broadly applicable to other real-time nucleic acid amplification tests by similarly modulating intercalating dye performance and is compatible with any fluorescence-based assay that can be run in a 96-well microplate format, making it especially valuable for POC and resource-limited settings.
