AAP Recommended Cardiac Screening Questions in Preparticipation Physical Evaluation Forms.

To evaluate the utilization of the American Academy of Pediatrics' (AP) cardiovascular screening questions within preparticipation physical evaluation forms from the 50 state high school athletic associations. We found that fewer than half of state forms incorporated all 10 AAP questions; moreover, a subset failed to adhere to criteria recommended by either the AAP or American Heart Association.

Limited Axial Interpretation of Coronary CT Angiography in the Emergency Department Setting.

PURPOSE: Incorporating coronary CT angiographic (CCTA) imaging into emergency department (ED) workflows has been limited by the need for 24/7 real-time postprocessing. The aim of this study was to determine whether interpretation of transaxial CCTA images alone (limited axial interpretation [LI]) is noninferior to interpretation of combined transaxial and multiplanar reformation images (full interpretation [FI]) in assessing patients with acute chest pain in the ED. METHODS: CCTA examinations from 74 patients were evaluated by two radiologists, one without dedicated CCTA training and one with basic CCTA experience. Each examination was evaluated three times in separate sessions, once by LI and twice by FI, in random order. Nineteen coronary artery segments were rated as having significant stenoses (≥50%) or not. Interreader agreement was assessed using Cohen's κ statistic. The primary analysis was whether the accuracy of LI for detecting significant stenosis was noninferior to that of FI at the patient level (margin = -10%). Secondary analyses included similar analyses of sensitivity and specificity, at both the patient and vessel levels. RESULTS: Interreader agreement for significant stenosis was good for both LI and FI (κ = 0.72 vs 0.70, P = .74). Average accuracy for significant stenosis at the patient level was 90.5% for LI and 91.9% for FI, with a difference of -1.4%. The accuracy of LI was noninferior to FI, because the confidence interval did not include the noninferiority margin. Noninferiority was also found for patient-level sensitivity and for accuracy, sensitivity, and specificity at the vessel level. CONCLUSIONS: LI of the coronary arteries using transaxial CCTA images may be sufficient for the detection of significant coronary artery disease in the ED setting.

Premorbid weight in pulmonary arterial hypertension.

Relationships between obesity and outcomes in pulmonary arterial hypertension (PAH) are complex. Previous work suggested obesity, occurring alongside PAH, may be associated with better survival. In our work, we suggest obesity prior to PAH development is associated with worse survival. This may add a novel temporal element to the "obesity-paradox."

Pacing in Pediatric Patients with Postoperative Atrioventricular Block.

Surgery for congenital heart disease may compromise atrioventricular (AV) nodal conduction, potentially resulting in postoperative AV block. In the majority of cases, AV nodal function recovers during the early postoperative period and may only require short-term pacing support, typically provided via temporary epicardial wires. Permanent pacing is indicated when the postoperative AV block persists for more than 7 to 10 days due to the risk of mortality if a pacemaker is not implanted. Although there is a subset of patients who may have late recovery of AV nodal function, those with continued postoperative AV block will need lifelong pacing therapy.

Development of PIVOT with MI: A motivational Interviewing-Based vaccine communication training for pediatric clinicians.

Delay or refusal of childhood vaccines is common and may be increasing. Pediatricians are parents' most trusted source for vaccine information, yet many struggle with how to communicate with parents who resist recommended vaccines. Evidence-based communication strategies for vaccine conversations are lacking. In this manuscript, we describe the development and perceived usefulness of a curriculum to train clinicians on a specific vaccine communication strategy as part of the PIVOT with MI study, a cluster randomized trial testing the effectiveness of this communication strategy on increasing childhood vaccination uptake among 24 pediatric practices in Colorado and Washington. The communication strategy is based on the existing evidence-based communication strategies of a presumptive format for initiating vaccine conversations and use of motivational interviewing if hesitancy persists. Focus groups and semi-structured interviews with pediatric clinicians helped inform the development of the training curriculum, which consisted of an introductory video module followed by 3 training sessions. Between September 2019 and January 2021, 134 pediatric clinicians (92 pediatricians, 42 advanced practice providers) participated in the training as part of the PIVOT with MI study. Of these, 92 % viewed an introductory video module, 93 % attended or viewed a baseline synchronous training, 82 % attended or viewed a 1st refresher training, and 77 % attended or viewed a 2nd refresher training. A follow-up survey was administered August 2020 through March 2021; among respondents (n = 100), >95 % of participants reported that each component of the training program was very or somewhat useful. These data suggest that the PIVOT with MI training intervention is a useful vaccine communication resource with the potential for high engagement among pediatric clinicians.

Ventricular Tachycardia in a Pediatric Patient with High-Risk Thrombotic Thrombocytopenia Purpura.

An 8-year-old previously healthy male was diagnosed with thrombotic thrombocytopenic purpura (TTP) and increased serum cardiac troponin I. Telemetry recorded non-sustained ventricular tachycardia, without ST-segment changes or other abnormalities on serial electrocardiogram. This case illustrates that cardiac monitoring by telemetry should be considered in high-risk TTP with elevated cardiac troponin.

Validation of a Process for Shared Decision-Making in Pediatrics.

OBJECTIVE: We sought to confirm, refute, or modify a 4-step process for implementing shared decision-making (SDM) in pediatrics that involves determining 1) if the decision includes >1 medically reasonable option; 2) if one option has a favorable medical benefit-burden ratio compared to other options; and 3) parents' preferences regarding the options; then 4) calibrating the SDM approach based on other relevant decision characteristics. METHODS: We videotaped a purposive sample of pediatric inpatient and outpatient encounters at a single US children's hospital. Clinicians from 7 clinical services (craniofacial, neonatology, oncology, pulmonary, pediatric intensive care, hospital medicine, and sports medicine) were eligible. English-speaking parents of children who participated in inpatient family care conferences or outpatient problem-oriented encounters with participating clinicians were eligible. We conducted individual postencounter interviews with clinician and parent participants utilizing video-stimulated recall to facilitate reflection of decision-making that occurred during the encounter. We utilized direct content analysis with open coding of interview transcripts to determine the salience of the 4-step SDM process and identify themes that confirmed, refuted, or modified this process. RESULTS: We videotaped 30 encounters and conducted 53 interviews. We found that clinicians' and parents' experiences of decision-making confirmed each SDM step. However, there was variation in the interpretation of each step and a need for flexibility in implementing the process depending on specific decisional contexts. CONCLUSIONS: The 4-step SDM process for pediatrics appears to be salient and may benefit from further guidance about the interpretation of each step and contextual factors that support a modified approach.

Symptoms and Comorbidities Differ Based on Race and Weight Status in Persons with HIV in the Northern United States: a Cross-Sectional Study.

BACKGROUND: Persons with HIV (PWHIV) on highly active antiretroviral treatments (HAART) may require specialized care based on health and demographic indicators. This study investigated the association of comorbidities, race, weight status, and gastrointestinal (GI) and cardiovascular (CV) symptoms among PWHIV. METHODS: The Symptom Checklist, Co-Morbidity Questionnaire, and Sociodemographic Questionnaire were used to assess weight status and GI and CV symptoms among 283 PWHIV. Data were analyzed using latent class analysis on John's Macintosh Project 13 Platform. RESULTS: Participants were majority Black (50%), 69% male, and 35% AIDS diagnosed. Ages were 25 to 66. Clusters included least symptomatic status, weight gain, and weight loss by Black and non-Black participants. The non-Black weight gain cluster reported a higher incidence of AIDS (70.6% vs 38.2%), nausea (70.6% vs 17.6%), diarrhea (70.6% vs 26.5%), and shortness of breath (58.8% vs 20.6%) compared to the Black weight gain cluster. The Black weight loss cluster reported a higher incidence of CV symptoms such as chest palpitations (42.2% vs 2.7%), chest pain (44.4% vs 8.1%), and shortness of breath (73.3% vs 35.1%). Moreover, the Black weight loss cluster reported a higher incidence of all GI symptoms with the most prominent being diarrhea (71.1% vs 48.6%) compared to the non-Black weight loss cluster. CONCLUSIONS: The existing racial disparities in health-related quality of life for PWHIV may be improved through precision health and nutrition modifications. Continued research is needed investigating differential health outcomes among PWHIV on HAART. CLINICAL TRIAL REGISTRATION NUMBER: NCT00222716. Registered 22 September 2005. Retrospectively registered, https://clinicaltrials.gov/ct2/show/NCT00222716?term=NCT00222716&draw=2&rank=1.

Preparticipation State Cardiac Screening Forms for Athletes.

BACKGROUND AND OBJECTIVES: Annual preparticipation physical evaluation (PPE) is used in the United States to screen adolescents for potential causes of sudden cardiac death. The American Heart Association recommends 14 screening elements of history and physical examination. This study sought to define the utilization of these screening elements by each of the 50 states before high school athletics. METHODS: PPE forms were obtained from the public website of the high school athletics governing body in every state. Form content was analyzed to identify which of the 14 screening elements were explicitly fulfilled. Additional PPE forms provided by private/parochial schools, other professional societies, or independent groups were excluded from this study. RESULTS: A total of 48 states (96%) had PPE forms posted online. The remaining 2 states (4%) deferred the specific method of PPE documentation to individual school districts and provided no standardized form. Of the 48 states providing PPE forms, 13 (27%) included all 14 American Heart Association screening elements. The median criteria included by each state was 11 (range 3-14). The 3 criteria most commonly absent were (1) the examination of femoral pulses to exclude coarctation (58%), (2) a family history of specific inherited cardiac disease (31%), and (3) personal history of hypertension (27%). CONCLUSIONS: Annual preparticipation forms are important screening tools. Only a minority of states include all 14 cardiac screening elements recommended by the American Heart Association.

Transfer patient imaging: secondary interpretation reimbursement.

INTRODUCTION: Trauma center radiologists vary widely in the degree to which they provide secondary interpretations for transferred patients' advanced imaging. A general perception of uncertainty over reimbursement for these exams often results in reluctance to provide routine overreads. The purpose of this study is to assess the difference in reimbursement rates between primary interpretations and secondary interpretations in the emergency department (ED) setting. MATERIALS AND METHODS: Billing records for the three CT procedures most commonly performed in a single, major level 1 trauma center ED from January 1, 2021, to December 31, 2021, constituted the dataset. Gross charges, total receipts, and payer status were recorded for each exam, and reimbursement rates calculated. RESULTS: In total, 19,754 exams met the inclusion criteria. Primary interpretation was performed on 16,507 (83.6%) exams and secondary interpretation on 3247 (16.4%). For the three CPT codes examined, the average reimbursement percentage was 32.9% for primary interpretation and 43.5% for secondary interpretation. The average reimbursement percentage for commercial payers was 56.5% for primary interpretation and 65.9% for secondary interpretation. The average reimbursement percentage for Health Insurance Exchange payers was 58.5% for primary interpretation and 59.5% for secondary interpretation. The average reimbursement percentage for Medicaid was 24.7% for primary interpretation and 39.9% for secondary interpretation. The average reimbursement percentage for Medicare was 31.1% for primary interpretation and 30.2% for secondary interpretation. The average reimbursement percentage for self-paying patients was 2.3% for primary interpretation and 3.5% for secondary interpretation. CONCLUSION: Regardless of payer status, reimbursement for secondary interpretation of the three most common transfer patients' CT exams is near or greater than that of primary interpretations.

Transfer Patient Imaging: Assessment of the Impact of Discrepancies Identified by Emergency Radiologists.

PURPOSE: Advanced imaging examinations of emergently transferred patients (ETPs) are overread to various degrees by receiving institutions. The practical clinical impact of these second opinions has not been studied in the past. The purpose of this study is to determine if emergency radiology overreads change emergency medicine decision making on ETPs in the emergency department (ED). METHODS: All CT and MRI examinations on patients transferred to a level I trauma center during calendar year 2018 were routinely overread by emergency radiologists and discrepancies with the outside report electronically flagged. All discrepant reports compared with the outside interpretations were reviewed by one of four emergency medicine physicians. Comparing the original and final reports, reviewers identified changes in patient management that could be attributed to the additional information contained in the final report. Changes in patient care were categorized as affecting ED management, disposition, follow-up, or consulting services. RESULTS: Over a 12-month period, 5,834 patients were accepted in transfer. Among 5,631 CT or MRI examinations with outside reports available, 669 examinations (12%) had at least one discrepancy in the corresponding outside report. In 219 examinations (33%), ED management was changed by discrepancies noted on the final report; patient disposition was affected in 84 (13%), outpatient follow-up in 54 (8%), and selection of consulting services in 411 (61%), and ED stay was extended in 544 (81%). Discrepant findings affected decision making in 613 of 669 of examinations (92%). CONCLUSION: Emergency radiology overreading of transferred patients' advanced imaging examinations provided actionable additional information to emergency medicine physicians in the care of 613 of 669 (92%) examinations with discrepant findings. This added value is worth the effort to design workflows to routinely overread CT and MRI examinations of ETPs.

Parent Attitudes Towards Childhood Vaccines After the Onset of SARS-CoV-2 in the United States.

OBJECTIVE: To understand the influence of a novel infectious disease epidemic on parent general attitudes about childhood vaccines. METHODS: We conducted a natural experiment utilizing cross-sectional survey data from parents of infants in Washington and Colorado participating in a larger trial that began on September 27, 2019. At enrollment, parents completed the short version of the Parental Attitudes about Childhood Vaccines (PACV-SF), a validated survey scored from 0 to 4, with higher scores representing more negative attitudes. The exposure variable was onset of the SARS-CoV-2 pandemic in the United States, with the before-period defined as September 27, 2019 to February 28, 2020 and the after-period defined as April 1, 2020-December 10, 2020, with the after-period further separated into proximate (April 1, 2020-July 31, 2020) and distant periods (August 1, 2020-December 10, 2020). The outcome variable was parent negative attitudes about childhood vaccines, defined as a score of ≥2 on the PACV-SF. We estimated the probability of the outcome after (vs before) the exposure using log-binomial regression with generalized estimating equations adjusted for demographic confounding variables. RESULTS: Among 4562 parents, the risk of negative attitudes was lower immediately after (vs before) SARS-CoV-2 onset (adjusted risk ratio [aRR] = 0.58; 95% confidence interval [CI], 0.36, 0.94; P = .027), but by August-December 2020, the average rate of negative attitudes was 35% higher than during April-July 2020 (aRR: 1.35; 95% CI: 1.13, 1.61; P = .0009). CONCLUSIONS: A reduced risk of negative general vaccine attitudes observed immediately after SARS-CoV-2 onset was quickly attenuated.

Echocardiographic characteristics of patients with antisynthetase syndrome.

Right ventricular (RV) dysfunction and pulmonary hypertension (PH) occurs in approximately one-third of patients with interstitial lung disease (ILD) and is associated with reduced 6-minute walk distance (6MWD), and increased hospitalizations and mortality. Although the impact of RV dysfunction and PH has been well described in several types of ILD, data is scarce on antisynthetase syndrome. Therefore, we sought to examine the presence of RV dysfunction and PH in patients with antisynthetase syndrome and the impact on clinical outcomes. We conducted a retrospective study of patients with antisynthetase syndrome. Seventy-five subjects were identified. Fifty-one (68%) subjects had echocardiographic data. Patients were grouped into those with normal fractional area change (FAC) ≥ 35% and reduced FAC < 35%. Clinical, echocardiographic, and right heart catheterization data were compared between the two groups. Subjects with FAC < 35% had lower diffusion capacity of the lung for carbon monoxide (29% vs. 47%, p = 0.004), fibrotic features on computed tomography of the chest (79% vs. 33%, p = 0.005), larger RV diameter (5.4 vs. 3.9 cm, p < 0.001), higher right atrial pressures (8 vs. 5 mmHg, p = 0.02), and required supplemental oxygen more frequently (100% vs. 44%, p < 0.001) compared to those with FAC ≥ 35%. We found no difference in 6MWD and hospitalizations between the two groups. The presence of RV dysfunction in antisynthetase syndrome may identify patients at risk of poor outcomes.

Postoperative Breath-Holding Spells Requiring Cardiopulmonary Resuscitation After Cardiopulmonary Bypass.

Breath-holding spells are common in childhood and can be associated with bradycardia and pulselessness. This report details severe breath-holding spells complicating postoperative management after atrial septal defect closure. The patient required cardiopulmonary resuscitation despite the use of a temporary pacemaker to prevent bradycardia. After multiple episodes of chest compressions, the decision was made to not intervene immediately to pulselessness and the patient was able to recover without further intervention.

Transfer Patient Imaging: A Novel Peer Feedback Program Beyond Institutional Boundaries.

BACKGROUND: At our level 1 trauma center, we overread cross-sectional scans on all transferred patients, initially reported by community radiologists (CR). We designed a unique peer feedback learning model to address discrepancies encountered with outside overreads with the goal of practice improvement on the part of the CRs. Although there is ample literature on internal peer review and peer learning programs, no publications address errors committed by peers outside institutional boundaries. In this paper we describe our model and report a survey analyzing the perception of the program by the CRs. MATERIALS AND METHODS: Outside CT and MR exams and reports of patients transferred to our level 1 trauma center were imported into PACS and prospectively overread by specialist trauma radiologists. Our report contained a summary of the outside findings as well as our findings. In the case of a significant discrepancy, a paper copy of our final report was sent by US mail to the originating CR. When the program had been active for 18 months, an invitation to participate in a survey was sent to all radiologists who had been sent reports. RESULTS: Eight thousand three hundred forty patients were transferred, of which 4331 (52%) had 9175 exams with outside reports (8666 CT scans and 509 MRI). One hundred seventy six final report letters containing significant discrepancies were sent to 139 individual radiologists. These 139 radiologists also later received our survey letter. Thirty-eight (27%) responses were received. Thirty-two respondents (84%) recalled receiving the report and reviewed the exam in question. Twenty-eight of them (85%) agreed with the overread and 30 (88%) believed that our feedback program should be continued. CONCLUSION: We have designed a novel peer feedback learning model to address discrepancies in outside overreads which is administratively simple and well received by the CRs getting feedback. Those CR who responded to the survey rated the experience favorably and wanted the practice continued, although the overall response rate did not allow statistical analysis. Also, institutions trying to design similar or new peer learning models can benefit from our experience.

Fidelity evaluation of the dialogue around respiratory illness treatment (DART) program communication training.

OBJECTIVE: To evaluate receipt fidelity of communication training content included in a multifaceted intervention known to reduce antibiotic over-prescribing for pediatric acute respiratory tract infections (ARTIs), by examining the degree to which clinicians implemented the intended communication behavior changes. METHODS: Parents were surveyed regarding clinician communication behaviors immediately after attending 1026 visits by children 6 months to < 11 years old diagnosed with ARTIs by 53 clinicians in 18 pediatric practices. Communication outcomes analyzed were whether clinicians: (A) provided both a combined (negative + positive) treatment recommendation and a contingency plan (full implementation); (B) provided either a combined treatment recommendation or a contingency plan (partial implementation); or (C) provided neither (no implementation). We used mixed effects multinomial logistic regression to determine whether these 3 communication outcomes changed between baseline and the time periods following each of 3 training modules. RESULTS: After completing the communication training, the adjusted probability of clinicians fully implementing the intended communication behavior changes increased by an absolute 8.1% compared to baseline (95% Confidence Interval [CI]: 2.4%, 13.8%, p = .005). CONCLUSIONS: Our findings support the receipt fidelity of the intervention's communication training content. PRACTICAL IMPLICATIONS: Clinicians can be trained to implement communication behaviors that may aid in reducing antibiotic over-prescribing for ARTIs.

What's in a Name? Report of the ACR Task Force on General Radiology and Multi-Subspecialization.

The ACR Council passed Resolution 47 at its 2020 annual meeting establishing a representative task force (TF) to explore the concept of the "multispecialty radiologist," previously proposed in 2012. The TF held eight virtual meetings over 8 months, considered data from a 2020 ACR Membership Tracking Survey, conducted a review of current literature, and collected anecdotal experience from TF members and ACR leadership. ACR legal counsel and a cross-section of ACR Commissions and Committees also provided input. The TF concluded that there is scant interest from the radiology community in the multispecialty radiologist title and no agreed-upon definition for the term. Radiologists may identify as diagnostic or subspecialty radiologists; however, the roles they fill in clinical practice include general, multispecialty, and subspecialized radiology. The TF proposes definitions for each of these terms to support radiologist recruitment aligned with optimal patient care in the practice community and to improve the quality of data collection about the field. To reduce ambiguity, the TF proposes adoption of the defined terms by the radiology community, including radiologist recruiters and employers, and suggests ways in which resident training and the ABR board examination can be adapted to support this new structure. Additionally, as part of an exploration of hyperspecialization and trainee preparedness for clinical practice, the TF discussed the challenges faced by community-based practices seeking to provide a full range of high-quality, radiologist-delivered diagnostic and interventional services to their patient populations.

Transfer patient imaging: discordances between community and subspecialist emergency radiologists.

PURPOSE: To determine the rate and nature of significant discordances between community and subspecialist emergency radiologists' interpretations of cross-sectional exams performed on patients transferred to our trauma center. METHODS: Outside hospital CT and MRI exams performed on transfer trauma patients are routinely overread by subspecialist emergency radiologists, specifying either concordance or discordance with the interpretation by the community radiologist. We evaluated the discordant reports for clinical significance, defined as an additional finding or difference in interpretation which was likely to affect patient management. The total rate of significant discordances, rate by modality, rate by body region, and rate per patient transferred were calculated. The most common errors were identified, and the distribution of errors among individual community radiologists was examined. RESULTS: 9175 exams were reviewed. Significant discordances were encountered in 4.1% of exams: 3.9% for CT and 6.7% for MRI; 5.1% for head and neck exams, 3.3% for spine, 3.8% for torso, and 2.9% for extremities. The discordance rate per patient transferred was 7.7%. The most common discordances involved missing injuries to the cranio-cervical junction, missing or misinterpreting vascular injuries in the neck, and incompletely characterizing facial fractures. Discordances were evenly spread among 220 community radiologists. CONCLUSION: There is frequent discordance between community and emergency radiologists' interpretations of CT and MRI exams, leading to a change in transferred patient management. Thus, trauma center radiologists provide added value overreading these patients' exams. It is difficult to predict which patients or exams will contain discordances, justifying routine overreading of all such exams.
