Novel techniques in performing extraoral ultrasound in diagnosing dental abscesses.

INTRODUCTION: Dental abscesses are a common reason patients present to the emergency department (ED). Facial and dental imaging are sometimes necessary to support the clinical diagnosis. While radiographs and computed tomography scans are frequently used, point-of-care ultrasound (US) offers several advantages, including decreased radiation exposure, reduced costs, and shorter patient length of stay. This report outlines the use of US in evaluating patients with suspected dental abscesses in the ED. DISCUSSION: The typical orofacial US techniques include examining the affected area for cobblestoning or fluid collections. To improve the accuracy of diagnoses, novel techniques such as the Oral Hydroscan (OHS) and the Tongue Pointing Techniques (TPT) may be employed in specific cases. The OHS utilizes a water-filled oral cavity to enhance the spatial resolution of ultrasound images, providing improved visualization of near-field structures and preventing air accumulation between the gingiva and the buccal mucosa. The TPT involves asking the patient to extend their tongue towards the affected area, pointing to the painful location, and serving as a visual reference for an extraoral US. CONCLUSION: US presents several advantages as an alternative imaging method for patients with suspected dental abscesses in the ED. Using innovative techniques such as the OHS and the TPT can further increase the visibility of tissue planes and help define the area of interest in these cases.

POCUS-first for nephrolithiasis: A Monte Carlo simulation illustrating cost savings, LOS reduction, and preventable radiation.

OBJECTIVES: Non-contrast computed tomography (NCCT) is the gold standard for nephrolithiasis evaluation in the emergency department (ED). However, Choosing Wisely guidelines recommend against ordering NCCT for patients with suspected nephrolithiasis who are <50 years old with a history of kidney stones. Our primary objective was to estimate the national annual cost savings from using a point-of-care ultrasound (POCUS)-first approach for patients with suspected nephrolithiasis meeting Choosing Wisely criteria. Our secondary objectives were to estimate reductions in ED length of stay (LOS) and preventable radiation exposure. METHODS: We created a Monte Carlo simulation using available estimates for the frequency of ED visits for nephrolithiasis and eligibility for a POCUS-first approach. The study population included all ED patients diagnosed with nephrolithiasis. Based on 1000 trials of our simulation, we estimated national cost savings in averted advanced imaging from this strategy. We applied the same model to estimate the reduction in ED LOS and preventable radiation exposure. RESULTS: Using this model, we estimate a POCUS-first approach for evaluating nephrolithiasis meeting Choosing Wisely guidelines to save a mean (±SD) of $16.5 million (±$2.1 million) by avoiding 159,000 (±18,000) NCCT scans annually. This resulted in a national cumulative decrease of 166,000 (±165,000) annual bed-hours in ED LOS. Additionally, this resulted in a national cumulative reduction in radiation exposure of 1.9 million person-mSv, which could potentially prevent 232 (±81) excess cancer cases and 118 (±43) excess cancer deaths annually. CONCLUSION: If adopted widely, a POCUS-first approach for suspected nephrolithiasis in patients meeting Choosing Wisely criteria could yield significant national cost savings and a reduction in ED LOS and preventable radiation exposure. Further research is needed to explore the barriers to widespread adoption of this clinical workflow as well as the benefits of a POCUS-first approach in other patient populations.

A Qualitative Exploration of Sacred Moments in Radiation Oncology.

Purpose: While there are many benefits to radiation oncology services, there can be emotional burdens in the care of patients with advanced cancer. Burnout is a prevalent problem in oncology. Existing literature suggests refocusing attention on providers' sense of purpose to protect against burnout. "Sacred moments" are moments of deep interconnection between people with accompanying spiritual emotions such as awe, joy, and gratitude. These moments naturally occur in health care settings, offering potential benefits to both patient and provider. Little is known about the prevalence and impact of sacred moments among health care workers in a radiation oncology setting. Methods and Materials: We conducted an exploratory qualitative study of 13 semi-structured interviews among physicians, registered nurses, and advanced practice providers of a radiation oncology consult service at a large National Cancer Institute-designated cancer center between March and May 2023. Interviews were recorded, transcribed, and analyzed to identify key themes. Data were systematically coded and analyzed in NVivo software and organized into a codebook organized by domains and themes. Results: Of the 13 health care workers interviewed, 12 interviewees reported experiencing at least one sacred moment during their clinical careers. None of the interviewees were initially familiar with the term; however, all understood the concept once explained. Interview findings were organized into four domains: (1) common elements, (2) impact, (3) barriers, and (4) provider reactions. Common elements included a moment of deep interconnection between provider and patient, often involving end-of-life patients. The impact of these moments was most commonly described as an increased sense of purpose in their role. Lack of time with patients was the most common barrier. Conclusions: Sacred moments are commonly experienced by health care workers in a radiation oncology consult service. They helped to humanize the patient, buffer against provider burnout, and increase a sense of purpose and job satisfaction.

Mindfulness-Based Interventions for the Reduction of Postoperative Pain in Hip and Knee Arthroplasty Patients: A Systematic Review and Meta-Analysis.

PURPOSE: The aim of this systematic review and meta-analysis is to evaluate the effect of mindfulness-based interventions (MBIs) on post-surgical pain in patients undergoing a total hip replacement (THR) or total knee replacement (TKR). METHODS: We performed a systematic review and meta-analysis in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A search of multiple databases, including PubMed and EMBASE, was performed for studies from database inception through March 2nd, 2022. Data were extracted, and pooled estimates of standardized mean differences in pain scores were calculated using a random effects model and inverse probability weighting. RESULTS: Two randomized control trials were eligible for inclusion (299 patients). The average ages of participants in each study were similar at 65.5 and 64.8 years, and both studies were predominantly female at 72.4% and 61.9%. The mindfulness intervention ranged from an eight-week program to a 20-minute session. Both individual studies reported statistically significant reductions in postoperative pain for MBI groups. The pooled standardized mean difference in pain scores for the MBI groups compared to the control groups was -1.94 (-3.39; -0.48). CONCLUSIONS: There exists preliminary evidence for the beneficial effect of MBIs on reducing the postoperative pain experience in this patient population. Given the significant consequences of postoperative pain and the necessity for non-opioid forms of analgesia, this topic represents a promising area of research that warrants future randomized control trials to better understand the role of MBIs for postoperative analgesia.
