Factors influencing the conduction of confidential conversations with adolescents in the emergency department: A multicenter, qualitative analysis.

BACKGROUND: Health care providers (HCPs) in the emergency department (ED) frequently must decide whether to conduct or forego confidential conversations with adolescent patients about sensitive topics, such as those related to mental health, substance use, and sexual and reproductive health. The objective of this multicenter qualitative analysis was to identify factors that influence the conduct of confidential conversations with adolescent patients in the ED. METHODS: In this qualitative study, we conducted semistructured interviews of ED HCPs from five academic, pediatric EDs in distinct geographic regions. We purposively sampled HCPs across gender, professional title, and professional experience. We used the Theoretical Domains Framework (TDF) to develop an interview guide to assess individual and system-level factors affecting HCP behavior regarding the conduct of confidential conversations with adolescents. Enrollment continued until we reached saturation. Interviews were recorded, transcribed, and coded by three investigators based on thematic analysis. We used the coded transcripts to collaboratively generate belief statements, which are first-person statements that reflect shared perspectives. RESULTS: We conducted 38 interviews (18 physicians, 11 registered nurses, five nurse practitioners, and four physician assistants). We generated 17 belief statements across nine TDF domains. Predominant influences on having confidential conversations included self-efficacy in speaking with adolescents alone, wanting to address sexual health complaints, maintaining patient flow, experiencing parental resistance and limited space, and having inadequate resources to address patient concerns and personal preconceptions about patients. Perspectives divided between wanting to provide focused medical care related only to their chief complaint versus self-identifying as a holistic medical HCP. CONCLUSIONS: The factors influencing the conduct of confidential conversations included multiple TDF domains, elucidating how numerous intersecting factors influence whether ED HCPs address sensitive adolescent health needs. These data suggest methods to enhance and facilitate confidential conversations when deemed appropriate in the care of adolescents in the ED.

Neurofeedback through the lens of reinforcement learning.

Despite decades of experimental and clinical practice, the neuropsychological mechanisms underlying neurofeedback (NF) training remain obscure. NF is a unique form of reinforcement learning (RL) task, during which participants are provided with rewarding feedback regarding desired changes in neural patterns. However, key RL considerations - including choices during practice, prediction errors, credit-assignment problems, or the exploration-exploitation tradeoff - have infrequently been considered in the context of NF. We offer an RL-based framework for NF, describing different internal states, actions, and rewards in common NF protocols, thus fashioning new proposals for characterizing, predicting, and hastening the course of learning. In this way we hope to advance current understanding of neural regulation via NF, and ultimately to promote its effectiveness, personalization, and clinical utility.

Computed Tomography Use in Children With Minor Head Trauma Presenting to 21 Community Emergency Departments Within an Integrated Health-Care System.

INTRODUCTION: Decreasing unnecessary cranial computed tomography (CT) use in pediatric head trauma patients remains important for emergency departments (EDs) across the US. Our study evaluated CT use in children with minor blunt head trauma in 21 community EDs within an integrated health-care system. METHODS: We studied all children younger than 18 years old presenting to 21 community EDs between 2016 through 2018 with acute minor blunt head trauma, defined by an algorithm of ED chief complaints and diagnoses. We excluded patients with traumatic brain injuries diagnosed in the prior year, a CT within 24 hours prior to the ED visit, or an ED Glasgow Coma Scale score of less than 14. RESULTS: Among 39,792 pediatric minor head trauma ED visits, the aggregate CT use proportion across all EDs was 12.9% [95% confidence interval (CI), 12.6-13.3%; facility-level range, 5.4-21.6%]. The 7 facilities that had previously received a clinical decision support system intervention implementing the Pediatric Emergency Care Applied Research Network rules during 2013 through 2014 had an aggregate mean CT ordering rate of 11.2% (95% CI, 10.7-11.7%; facility-level range, 5.4-14.3%) compared to 14.1% (95% CI, 13.6-14.5%; facility-level range, 7.3-21.6%) for the nonintervention facilities. CONCLUSION: CT use for children with minor blunt head trauma in the community EDs of an integrated health-care system was low and stable across facilities from 2016 through 2018. This may be indicative of the safe stewardship of resources in the system, including the absence of financial or medicolegal incentives to scan very low-risk patients as well the availability of resources for close patient follow-up.

Emergency physicians' knowledge and attitudes of clinical decision support in the electronic health record: a survey-based study.

OBJECTIVES: The objective was to investigate clinician knowledge of and attitudes toward clinical decision support (CDS) and its incorporation into the electronic health record (EHR). METHODS: This was an electronic survey of emergency physicians (EPs) within an integrated health care delivery system that uses a complete EHR. Randomly assigned respondents completed one of two questionnaires, both including a hypothetical vignette and self-reported knowledge of and attitudes about CDS. One vignette version included CDS, and the other did not (NCDS). The vignette described a scenario in which a cranial computed tomography (CCT) is not recommended by validated prediction rules (the Pediatric Emergency Care Applied Research Network [PECARN] rules). In both survey versions, subjects responded first with their likely approach to evaluation and then again after receiving either CDS (the PECARN prediction rules) or no additional support. Descriptive statistics were used for self-reported responses and multivariate logistic regression was used to identify predictors of self-reported knowledge and use of the PECARN rules, as well as use of vignette responses. RESULTS: There were 339 respondents (68% response rate), with 172 of 339 (51%) randomized to the CDS version. Initially, 25% of respondents to each version indicated they would order CCTs. After CDS, 30 of 43 (70%) of respondents who initially would order CCTs changed their management decisions to no CCT versus two of 41 (5%) with the NCDS version (chi-square, p = 0.003). In response to self-report questions, 81 of 338 respondents (24%) reported having never heard of the PECARN prediction rules, 122 of 338 (36%) were aware of the rules but not their specifics, and 135 of 338 (40%) reported knowing the rules and their specifics. Respondents agreed with favorable statements about CDS (75% to 96% agreement across seven statements) and approaches to its implementation into the EHR (60% to 93% agreement across seven statements). In multivariable analyses, EPs with tenure of 5 to 14 years (odds ratio [AOR] = 0.51, 95% confidence interval [CI] = 0.30 to 0.86) and for 15 years or more (AOR = 0.37, 95% CI = 0.20 to 0.70) were significantly less likely to report knowing the specifics of the PECARN prediction rules compared with EPs who practiced for fewer than 5 years. In addition, in the initial vignette responses (across both versions), physicians with ≥15 years of ED tenure compared to those with fewer than 5 years of experience (AOR = 0.30, 95% CI = 0.13 to 0.69), and those reporting knowing the specifics of the PECARN prediction rules were less likely to order CCTs (AOR = 0.53, 95% CI = 0.30 to 0.92). CONCLUSIONS: EPs incorporated pediatric head trauma CDS via the EHR into their clinical judgment in a hypothetical scenario and reported favorable opinions of CDS in general and their inclusion into the EHR.

Accuracy of plain radiographs to exclude the diagnosis of intussusception.

OBJECTIVES: To prospectively determine the test characteristics of the 3-view abdominal radiograph to decrease the likelihood of ileocolic intussusception. METHODS: We conducted a prospective cross-sectional study of children aged 3 months to 3 years suspected of having intussusception at a children's hospital emergency department. Clinicians obtained supine, prone, and left lateral decubitus radiographs. We determined the presence or absence of intussusception by air enema, ultrasound, operative report, or clinical follow-up. A masked pediatric radiologist reviewed all radiographs. The criteria evaluated were whether air was visualized in the ascending colon on each view and in the transverse colon on the supine view. RESULTS: Nineteen (14.8%) of 128 patients had intussusception. Using air in the ascending colon on all 3 views as the diagnostic criteria, the test characteristics of the 3-view radiograph were sensitivity, 100% (95% confidence interval [CI], 79.1-100); specificity, 17.4% (95% CI, 11.1-26.1); negative predictive value, 100% (95% CI, 79.1-100); and likelihood ratio of a negative test, 0. When 2 or more of 3 views had air in the ascending colon, sensitivity decreased to 89.5% (95% CI, 75.7-100) and specificity improved to 45.0% (95% CI, 35.6-54.3). Air in the transverse colon had moderate sensitivity, 84.2% (95% CI, 67.8-100), but further improved specificity, 63.3% (95% CI, 54.2-72.4). CONCLUSIONS: The presence of air in the ascending colon on the 3-view abdominal radiograph can decrease the likelihood of or exclude intussusception. When clinical suspicion is low, the presence of specific criterion on a 3-view abdominal radiograph series may obviate the need for further studies.

Serotonin selectively modulates reward value in human decision-making.

Establishing a function for the neuromodulator serotonin in human decision-making has proved remarkably difficult because if its complex role in reward and punishment processing. In a novel choice task where actions led concurrently and independently to the stochastic delivery of both money and pain, we studied the impact of decreased brain serotonin induced by acute dietary tryptophan depletion. Depletion selectively impaired both behavioral and neural representations of reward outcome value, and hence the effective exchange rate by which rewards and punishments were compared. This effect was computationally and anatomically distinct from a separate effect on increasing outcome-independent choice perseveration. Our results provide evidence for a surprising role for serotonin in reward processing, while illustrating its complex and multifarious effects.
