Attitudes Toward COVID-19 Vaccines Among Pregnant and Recently Pregnant Individuals.

Importance: Pregnant people and infants are at high risk of severe COVID-19 outcomes. Understanding changes in attitudes toward COVID-19 vaccines among pregnant and recently pregnant people is important for public health messaging. Objective: To assess attitudinal trends regarding COVID-19 vaccines by (1) vaccination status and (2) race, ethnicity, and language among samples of pregnant and recently pregnant Vaccine Safety Datalink (VSD) members from 2021 to 2023. Design, Setting, and Participants: This cross-sectional surveye study included pregnant or recently pregnant members of the VSD, a collaboration of 13 health care systems and the US Centers for Disease Control and Prevention. Unvaccinated, non-Hispanic Black, and Spanish-speaking members were oversampled. Wave 1 took place from October 2021 to February 2022, and wave 2 took place from November 2022 to February 2023. Data were analyzed from May 2022 to September 2023. Exposures: Self-reported or electronic health record (EHR)-derived race, ethnicity, and preferred language. Main Outcomes and Measures: Self-reported vaccination status and attitudes toward monovalent (wave 1) or bivalent Omicron booster (wave 2) COVID-19 vaccines. Sample- and response-weighted analyses assessed attitudes by vaccination status and 3 race, ethnicity, and language groupings of interest. Results: There were 1227 respondents; all identified as female, the mean (SD) age was 31.7 (5.6) years, 356 (29.0%) identified as Black race, 555 (45.2%) identified as Hispanic ethnicity, and 445 (36.3%) preferred the Spanish language. Response rates were 43.5% for wave 1 (652 of 1500 individuals sampled) and 39.5% for wave 2 (575 of 1456 individuals sampled). Respondents were more likely than nonrespondents to be White, non-Hispanic, and vaccinated per EHR. Overall, 76.8% (95% CI, 71.5%-82.2%) reported 1 or more COVID-19 vaccinations; Spanish-speaking Hispanic respondents had the highest weighted proportion of respondents with 1 or more vaccination. Weighted estimates of somewhat or strongly agreeing that COVID-19 vaccines are safe decreased from wave 1 to 2 for respondents who reported 1 or more vaccinations (76% vs 50%; χ21 = 7.8; P < .001), non-Hispanic White respondents (72% vs 43%; χ21 = 5.4; P = .02), and Spanish-speaking Hispanic respondents (76% vs 53%; χ21 = 22.8; P = .002). Conclusions and Relevance: Decreasing confidence in COVID-19 vaccine safety in a large, diverse pregnant and recently pregnant insured population is a public health concern.

Dermatology Life Quality Index survey in patients with Down syndrome and caregivers.

Down syndrome (DS) is associated with many dermatological conditions, including hidradenitis suppurativa, folliculitis, and alopecia areata. Despite the high incidence of skin conditions in this population, there are no quality of life (QoL) studies in the dermatology literature focused on patients with DS or their caregivers. The frequently used QoL assessment tool, the Dermatology Life Quality Index (DLQI), has yet to be studied in this population. This study addresses these disparities by capturing how various skin conditions affect the QoL of people with DS and their caregivers and assessing the utility of the DLQI.

Associations between low body weight, weight loss, and medical instability in adults with eating disorders.

OBJECTIVE: The physical complications of atypical anorexia nervosa remain understudied, with most studies completed in adolescents. This study seeks to examine the impact of various weight measures as predictors of medical instability in a large cohort of adult eating disorder patients. METHODS: In this retrospective cohort study, the impact of admission body mass index (BMI), weight suppression, and recent weight loss (the rate of weight loss within the last 12 months) toward the development of medical complications of malnutrition were examined. Multivariable logistic regression assessed the association of binary clinical outcomes of interest with recent weight loss and weight suppression (adjusting for age, admission BMI, gender, and purging behaviors). Odds ratios (OR) and 99% confidence intervals were reported. RESULTS: Greater recent weight loss increased the odds of developing low prealbumin and reduced hand grip strength. A greater weight suppression was associated with increased likelihood of amenorrhea, reduced systolic blood pressure, nadir hemoglobin, and weekly weight gain upon nutritional rehabilitation. Lower admission BMI was predictive of all the medical outcomes examined, with the exception of bradycardia, and was generally the strongest predictor based on standardized coefficients. DISCUSSION: Recent weight loss and weight suppression are predictive of some of the physiologic changes of malnutrition, although low BMI is seemingly the greatest predictor for the development of these complications. These findings suggest that some patients with aggressive weight suppression and/or acute weight loss would benefit from medical stabilization, although this needs to be further defined. PUBLIC SIGNIFICANCE: In adults, low BMI seems to be a better predictor of medical complications than weight suppression or aggressive recent weight loss. In adults, greater weight suppression is associated with increased likelihood of amenorrhea, reduced systolic blood pressure, nadir hemoglobin, and weight gain upon nutritional rehabilitation.

Interventions to de-implement unnecessary antibiotic prescribing for ear infections (DISAPEAR Trial): protocol for a cluster-randomized trial.

BACKGROUND: Watchful waiting management for acute otitis media (AOM), where an antibiotic is used only if the child's symptoms worsen or do not improve over the subsequent 2-3 days, is an effective approach to reduce antibiotic exposure for children with AOM. However, studies to compare the effectiveness of interventions to promote watchful waiting are lacking. The objective of this study is to compare the effectiveness and implementation outcomes of two pragmatic, patient-centered interventions designed to facilitate use of watchful waiting in clinical practice. METHODS: This will be a cluster-randomized trial utilizing a hybrid implementation-effectiveness design. Thirty-three primary care or urgent care clinics will be randomized to one of two interventions: a health systems-level intervention alone or a health systems-level intervention combined with use of a shared decision-making aid. The health systems-level intervention will include engagement of a clinician champion at each clinic, changes to electronic health record antibiotic orders to facilitate delayed antibiotic prescriptions as part of a watchful waiting strategy, quarterly feedback reports detailing clinicians' use of watchful waiting individually and compared with peers, and virtual learning sessions for clinicians. The hybrid intervention will include the health systems-level intervention plus a shared decision-making aid designed to inform decision-making between parents and clinicians with best available evidence. The primary outcomes will be whether an antibiotic was ultimately taken by the child and parent satisfaction with their child's care. We will explore the differences in implementation effectiveness by patient population served, clinic type, clinical setting, and organization. The fidelity, acceptability, and perceived appropriateness of the interventions among different clinician types, patient populations, and clinical settings will be compared. We will also conduct formative qualitative interviews and surveys with clinicians and administrators, focus groups and surveys of parents of patients with AOM, and engagement of two stakeholder advisory councils to further inform the interventions. DISCUSSION: This study will compare the effectiveness of two pragmatic interventions to promote use of watchful waiting for children with AOM to reduce antibiotic exposure and increase parent satisfaction, thus informing national antibiotic stewardship policy development. CLINICAL TRIAL REGISTRATION: NCT06034080.

Reducing length of antibiotics for children with ear infections: protocol for a cluster-randomized trial in the USA.

Aim: Preventing unnecessarily long durations of antibiotic therapy is a key opportunity to reduce antibiotic overuse in children 2 years of age and older with acute otitis media (AOM). Pragmatic interventions to reduce durations of therapy that can be effectively scaled and sustained are urgently needed. This study aims to fill this gap by evaluating the effectiveness and implementation outcomes of two low-cost interventions of differing intensities to increase guideline-concordant antibiotic durations in children with AOM. Methods: The higher intensity intervention will consist of clinician education regarding guideline-recommended short durations of antibiotic therapy; electronic health record (EHR) prescription field changes to promote prescribing of recommended short durations; and individualized clinician audit and feedback on adherence to recommended short durations of therapy in comparison to peers, while the lower intensity intervention will consist only of clinician education and EHR changes. We will explore the differences in implementation effectiveness by patient population served, clinician type, clinical setting and organization as well as intervention type. The fidelity, feasibility, acceptability and perceived appropriateness of the interventions among different clinician types, patient populations, clinical settings and intervention type will be compared. We will also conduct formative qualitative interviews with clinicians and administrators and focus groups with parents of patients to further inform the interventions and study. The formative evaluation will take place over 1.5 years, the interventions will be implemented over 2 years and evaluation of the interventions will take place over 1.5 years. Discussion: The results of this study will provide a framework for other healthcare systems to address the widespread problem of excessive durations of therapy for AOM and inform national antibiotic stewardship policy development. Clinical Trial Registration: NCT05608993 (ClinicalTrials.gov).

Cost-Effectiveness of AF Screening With 2-Week Patch Monitors: The mSToPS Study.

BACKGROUND: The mSToPS study (mHealth Screening to Prevent Strokes) reported screening older Americans at risk for atrial fibrillation (AF) and stroke using 2-week patch monitors was associated with increased rates of AF diagnosis and anticoagulant prescription within 1 year and improved clinical outcomes at 3 years relative to matched controls. Cost-effectiveness of this AF screening approach has not been explored. METHODS: We conducted a US-based health economic analysis of AF screening using patient-level data from mSToPS. Clinical outcomes, resource use, and costs were obtained through 3 years using claims data. Individual costs, survival, and quality-adjusted life years (QALYs) were projected over a lifetime horizon using regression modeling, US life tables, and external data where needed. Adjustment between groups was performed using propensity score bin bootstrapping. RESULTS: Screening participants (mean age, 74 years, 41% female, median CHA2DS2-VASC score 3) wore on average 1.7 two-week monitors at a mean cost of $614/person. Over 3 years, outpatient visits were more frequent for monitored than unmonitored individuals (difference 190 per 100 patient-years [95% CI, 82-298]), but emergency department visits (-8.3 [95% CI, -12.6 to -4.1]) and hospitalizations (-15.2 [CI, -22 to -8.6]) were less frequent. Total adjusted 3-year costs were slightly higher (mean difference, $1551 [95% CI, -$1047 to $4038]) in the monitoring group. In patient-level projections, the monitoring group had slightly greater quality-adjusted survival (8.81 versus 8.71 QALYs, difference, 0.09 [95% CI, -0.05 to 0.24]) and slightly higher lifetime costs, resulting in an incremental cost-effectiveness ratio of $36 100/QALY gained. With bootstrap resampling, the incremental cost-effectiveness ratio for monitoring was <$50 000/QALY in 64% of study replicates, and <$150 000/QALY in 91%. CONCLUSIONS: Using lifetime projections derived from the mSToPS study, we found that AF screening using 2-week patch monitors in older Americans was associated with high economic value. Confirmation of these uncertain findings in a randomized trial is warranted. REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT02506244.

Gabapentin, melatonin, and acepromazine combination prior to hospital visits decreased stress scores in aggressive and anxious dogs in a prospective clinical trial.

OBJECTIVE: To evaluate sedative and behavioral effects of a client-administered preappointment protocol with PO gabapentin and melatonin and oral-transmucosal acepromazine (GMA protocol). ANIMALS: 45 client-owned dogs between 1 and 12 years old that underwent standardize examinations between February and August 2021. METHODS: In this clinical trial, dogs with a history of anxiety, fearfulness, and/or aggression during hospital visits were assessed and videotaped before (baseline) and after administration of the GMA protocol. For the second visit, owners administered PO gabapentin (20 to 25 mg/kg) in the evening prior to the next visit and PO gabapentin (20 to 25 mg/kg), PO melatonin (3 to 5 mg/dog), and oral-transmucosal acepromazine (0.05 mg/kg) 90 to 120 minutes prior to the second appointment. Examinations were performed, and behavioral stress and sedation levels were evaluated with semiquantitative rating scales. Randomized videos were analyzed, and a paired t test was used to compare stress and sedation scores between baseline and GMA. A Pearson correlation coefficient was used to evaluate the effect of age on the scores. RESULTS: Stress scores were significantly lower after the GMA protocol, and sedation scores were significantly higher when compared to baseline (21.84 vs 27.11 and 1.39 vs 0.68, respectively). A significant correlation between increasing age and lower stress scores post-GMA and higher sedation scores post-GMA were observed. CLINICAL RELEVANCE: Preappointment administration of the GMA protocol reduced signs of stress, fear, and fear-based aggression during hospital visits and provided sedation in this dog population. This protocol could represent an adjunct tool for veterinarians to improve quality of care and reduce animal-related injury.

Clinical Characteristics Associated with Musculoskeletal Extracutaneous Manifestations in Pediatric and Adult Morphea: A Prospective, Cohort Study.

Morphea is an autoimmune condition of the skin associated with functional sequelae resulting from musculoskeletal involvement. Systematic investigation of risk for musculoskeletal involvement is limited, particularly in adults. This knowledge gap impairs patient care because practitioners are unable to risk stratify patients. To address this gap, we determined the frequency, distribution, and type of musculoskeletal (MSK) extracutaneous manifestations affecting joint and bone with overlying morphea lesions using cross-sectional analysis of 1,058 participants enrolled in two prospective cohort registries (Morphea in Children and Adults Cohort [n = 750] and National Registry for Childhood Onset Scleroderma [n = 308]). Additional analysis included the identification of clinical features associated with MSK extracutaneous manifestations. MSK extracutaneous manifestations occurred in 274 of 1,058 participants (26% overall, 32% pediatric, and 21% adults). Children had a limited range of motion of larger joints (i.e., knees/hips/shoulders), whereas the involvement of smaller joints (i.e., toes/temporomandibular joint) was more common in adults. Multivariable logistic regression showed that deep tissue involvement had the strongest association with musculoskeletal features, with a lack of deep tissue involvement having a negative predictive value of 90% for MSK extracutaneous manifestations. Our results underscore the need to evaluate MSK involvement in adult and pediatric patients and the utility of using depth of involvement in addition to anatomic distribution to risk stratify patients.

Post-pubertal developmental trajectories of laryngeal shape and size in humans.

Laryngeal morphotypes have been hypothesized related to both phonation and to laryngeal pathologies. Morphotypes have not been validated or demonstrated quantitatively and sources of shape and size variation are incompletely understood but are critical for the explanation of behavioral changes (e.g., changes of physical properties of a voice) and for therapeutic approaches to the larynx. This is the first study to take this crucial step and results are likely to have implications for surgeons and speech language pathologists. A stratified human sample was interrogated for phenotypic variation of the vocal organ. First, computed tomography image stacks were used to generate three-dimensional reconstructions of the thyroid cartilage. Then cartilage shapes were quantified using multivariate statistical analysis of high dimensional shape data from margins and surfaces of the thyroid cartilage. The effects of sex, age, body mass index (BMI) and body height on size and shape differences were analyzed. We found that sex, age, BMI and the age-sex interaction showed significant effects on the mixed sex sample. Among males, only age showed a strong effect. The thyroid cartilage increased in overall size, and the angulation between left and right lamina decreased in older males. Age, BMI and the age-height interaction were statistically significant factors within females. The angulation between left and right lamina increased in older females and was smaller in females with greater BMI. A cluster analysis confirmed the strong age effect on larynx shape in males and a complex interaction between the age, BMI and height variables in the female sample. The investigation demonstrated that age and BMI, two risk factors in a range of clinical conditions, are associated with shape and size variation of the human larynx. The effects influence shape differently in female and male larynges. The male-female shape dichotomy is partly size-dependent but predominantly size-independent.

Lumbar multifidus muscle ultrasound imaging: Is handheld technology reliable?

BACKGROUND: Advancement in ultrasound imaging technology has led to the development of handheld devices that are more accessible to physical therapists due to decreased cost, reduced size, and improved ease of use relative to current established units. Physical therapists use ultrasound imaging of the lumbar multifidus muscle (LMM) to assist in rehabilitation of patients with lumbar pathology. OBJECTIVES: To identify the inter-device reliability of measuring the LMM thickness during a sustained contraction when comparing handheld (Butterfly iQ+) and established (SonoSite M-Turbo) ultrasound units. A secondary purpose was to determine the reliability of a student physical therapist using both devices. DESIGN: A reliability measurement study METHOD: A blinded examiner identified the LMM at the L4 vertebral level and measured the thickness of the contracted muscle utilizing both the handheld and established ultrasound devices. ICC values were calculated to determine the inter-device and intra-rater reliability. RESULTS: The study included 42 healthy participants, 30 females and 12 males, with a mean age of 38.5 years. The inter-device reliability during a sustained LMM contraction was excellent (ICC = 0.92, 95% CI: 0.87-0.94) and the intra-rater reliability was good for both the handheld (ICC = 0.85, 95% CI: 0.73-0.92) and established (ICC = 0.89, 95% CI: 0.82-0.93) ultrasound units. CONCLUSION: Results support the use of handheld ultrasound by physical therapists and students to measure the LMM thickness. Future studies could investigate the reliability of handheld ultrasound in a variety of musculoskeletal and pathological structures important to PT practice.

Efficacy, perception, and utilization of pediatric teledermatology: A systematic review.

Background: The use of teledermatology abruptly expanded with the arrival of COVID-19. Here, we review recent studies regarding the efficacy, perception, and utilization of telemedicine in the pediatric population. Objective: To evaluate the current state of pediatric teledermatology. Methods: A literature search was performed using the terms "pediatric," "teledermatology," "dermatology," "telemedicine" and "telehealth" in PubMed, Scopus, Embase, and Google Scholar. 44 articles published between 2008 and 2022 were included. Results: Diagnostic concordance between pediatric teledermatologist and in-person dermatologist ranged from 70.1% to 89%. Conditions treated with pediatric teledermatology were similar to those treated in-person. The rate of in-person follow-up after an initial telemedicine appointment pre and postpandemic was 12% to 51.9% and 13.5% to 28.1%, respectively. Patient satisfaction with teledermatology was between 70% to 98% and provider satisfaction was approximately 95%. The integration of teledermatology can reduce missed appointments and wait times among pediatric patients. However, considerable technological challenges exist, particularly in underserved communities. Globally, teledermatology may expand access to care though limited literature exists regarding its use in pediatric populations. Conclusion: Telemedicine is effective for the diagnosis and treatment of many dermatological conditions in children, with high patient and provider satisfaction. Implementation of teledermatology can potentially increase access to care both locally and globally, but obstacles to engagement remain.

The burden of Chronic Pelvic Pain (CPP): Costs and quality of life of women and men with CPP treated in outpatient referral centers.

INTRODUCTION: Chronic Pelvic Pain (CPP) is a complex, multifaceted condition that affects both women and men. There is limited literature on the cost utilization the healthcare system and CPP patients incur. The purpose of this analysis is to characterize the overall healthcare utilization, cost burden, and quality-of-life restrictions experienced by CPP patients using data from an outpatient pelvic rehabilitation practice. METHODS: Healthcare utilization data was gathered by systematically reviewing and analyzing data from new patient visit progress notes stored in the clinic's electronic health records (EHR). We obtained in-network costs by using the FAIR Health Consumer online database. Overall costs were then calculated as the utilization times the per-unit costs from the FAIR database. Additionally, data on patients' visual analogue scale (VAS), absenteeism, presenteeism emergency room visits, usage of common pain medications, use of diagnostics, and participation in common treatment modalities was gathered. RESULTS: Data from 607 patients was used. The overall cost burden per patient for all surgeries combined was $15,750 for in-network services. The cost burden for diagnostics was $5,264.22 and treatments was $8,937 per patient for in-network treatments. CONCLUSION: Chronic Pelvic Pain was found to have a large cost burden of $29,951 for in-network services which includes treatments, diagnostics, and surgeries. This analysis sets the stage for future investigations involving data on costs of medications that patients have tried prior to presenting to us and costs associated with work hours lost.

Intramuscular alfaxalone with or without buprenorphine or hydromorphone provides sedation with minimal adverse effects in healthy rabbits (Oryctolagus cuniculus) in a randomized blinded controlled trial.

OBJECTIVE: To evaluate the effects of alfaxalone administered IM with or without buprenorphine or hydromorphone in healthy rabbits (Oryctolagus cuniculus). ANIMALS: 24 male rabbits undergoing elective orchiectomy between August 21, 2021, and November 6, 2021. PROCEDURES: In this controlled clinical trial, rabbits were randomly assigned to receive alfaxalone (4 mg/kg, IM) alone (group A; n = 8) or with buprenorphine (0.03 mg/kg, IM; group BA; 8) or hydromorphone (0.1 mg/kg, IM; group HA; 8). Vital signs and sedation scores were recorded immediately prior to (T0) and 10 minutes after (T1) treatment. Ease of IV catheter placement and pain scores were also evaluated. All rabbits received ketamine (2.5 mg/kg, IV), midazolam (0.13 mg/kg, IV), and meloxicam (0.5 mg/kg, SC) before orchiectomy but after IM treatments. Results were compared across groups with ANOVA or Fisher exact tests and across time with paired t tests. RESULTS: Sedation score, median time to recumbency, and ease of catheter placement did not differ among groups. Supraglottic airway device placement was possible for 1 rabbit in group A, 1 in group BA, and 2 in group HA. Mean respiratory rate at T1 versus T0 was significantly decreased for groups BA (63.8 vs 128.6 breaths/min) and HA (66.7 vs 123.2 breaths/min). Mean postoperative pain scores were significantly lower for rabbits in group HA (0.58), compared with those in groups A (2.25) and BA (2.06). CLINICAL RELEVANCE: All 3 treatments provided reliable sedation; however, alfaxalone (4 mg/kg, IM) combined with hydromorphone (0.1 mg/kg, IM) may be a better choice for painful procedures.

Rock-Climbing Shoes: A Survey of Attitudes and Practices.

BACKGROUND: There is a paucity of literature regarding rock climbing footwear. Rock climbers anecdotally voice numerous complaints regarding their current footwear. In an effort to improve existing rock-climbing footwear, implementation of a survey tool assessing the attitudes and practices of rock climbers was undertaken. METHODS: A Web-based survey was developed to assess the demographics, attitudes, and practices of individuals active in rock climbing, with a focus on footwear. RESULTS: Forty-five of the 417 respondents were male and 55% were female. The average years climbing was 7, with a majority of respondents in the 18- to 34-year-old category. The majority climbed 5 to 10 hours/week. Eighty percent identified as intermediate or advanced climbers. Climbing shoes were an average of 0.83 size smaller than the climber's street shoes. The more elite the climber, the greater the mismatch. Overall satisfaction with current rock-climbing shoes was 88%; however, as the age of climber and number of years of participation increased, the level of satisfaction decreased. The most frequently reported problems with shoes included inconsistent sizing between brands and poor heel fit. The most commonly reported locations of pain were the toes and heel. CONCLUSIONS: The authors concluded the following: 1) a surprisingly high satisfaction with current rock-climbing shoes was reported; 2) the difference in size between climbing shoes and street shoes was less than expected; 3) more shoe fitting problems were experienced by those with the most experience in climbing and those who spend the most time climbing; 4) the most common locations for experiencing pain were the toes and the posterior heel or Achilles tendon; 5) higher than expected satisfaction levels with climbing shoes contrasted with the very high number of specific complaints and recommendations for improvement; and 6) because of the increasing popularity of rock climbing, foot care providers should learn about the various types of climbing and the shoe gear needs that result therefrom.

A proposed algorithm for evaluation and management of pediatric hemophilia patients who present to the emergency department with head trauma.

Hemophilia is the deficiency of plasma clotting factor VIII (hemophilia A) or IX (hemophilia B) where management focuses on the prevention and treatment of acute bleeding symptoms and their sequelae. The most concerning risk is for life-threatening bleeding, including intracranial hemorrhage (ICH), which is caused by head trauma. Guidelines exist for the evaluation and management of pediatric head trauma, including the Pediatric Emergency Care Applied Research Network (PECARN) protocol, but limited evidence exists for when hemophilia patients present to the emergency department (ED), specifically with head trauma. Literature is limited regarding ICH and hemophilia, which further supports the culture of uncertainty among providers. The objective of this study is to conduct a retrospective chart review to determine the prevalence and clinical characteristics of ICH, and to describe computed tomography (CT) scan use in hemophilia patients who present to Phoenix Children's Hospital (PCH) ED with head trauma from January 1, 2007 to June 1, 2019. A total of 89 ED visits and 43 patients met inclusion criteria, and prevalence of ICH was determined to be 4% with the patients presenting with varied clinical characteristics and few commonalities. Using these data, we propose a new algorithm to aid clinicians in determining the need for CT scan in pediatric hemophilia patients who present to the ED with head trauma.

Opioid-Free Anesthesia and Certified Registered Nurse Anesthetists: Barriers to Implementation.

While knowledge surrounding opioid-free anesthesia (OFA) has increased in current literature, there is an absence of research specific to nurse anesthesia practice. This study aimed to identify the number of surveyed Certified Registered Nurse Anesthetists (CRNAs) who incorporated OFA into practice and uncovered barriers to its implementation. This quantitative survey solicited data from 2,883 CRNAs across the United States. Of the participants, 81% administered OFA, and 88% felt that OFA techniques are beneficial in anesthesia practice. The results of the survey revealed that gender may be a barrier to the implementation of OFA. Female respondents were less likely to administer OFA often due to the facility culture. The level of education also influenced how CRNAs perceived their facility's culture as a barrier. Perceived access to a variety of multimodal anesthetics was also problematic. While most of those surveyed had administered OFA and acknowledged its benefit, barriers to wider implementation still exist.

Assessment of communication and physical exam skills: A comparison of students, faculty and standardized patients.

PURPOSE/OBJECTIVES: The objective of this retrospective study was twofold: it aimed to investigate dental students' communication and physical exam self-assessment skills by comparing students' self-evaluations with those completed by faculty and standardized patients (SPs). Second, it aimed to compare faculty and SPs assessment of students' communication skills. METHODS: At the end of their first year of training, students (n = 127), participated in one SP encounter about an initial dental consultation. Students completed self-assessment before receiving feedback from faculty (n = 19) and SPs (n = 19). The data source included evaluation forms submitted by students, faculty and SPs. The Wilcoxon signed rank test was used to compare the overall scores between groups. Agreement between evaluations items were analyzed with McNemar's test (p < 0.05). RESULTS: Overall, there were no statistically significant differences in how students and faculty graded for either communication (p = 0.6724) or physical exam (p = 0.1921) skills. However, both students and faculty provided less favorable marks than SPs for communication skills with a statistically significant difference in the overall grading between both students and SPs (p = 0.0146) and between faculty and SPs (p = 0.0045). CONCLUSIONS: While there was disagreement between students and faculty versus SPs, they weren't meaningful differences in scores and the dissimilarities mainly consisted of ratings of explanation skills. We suggest that, when applicable, dental student's self-evaluations may represent an alternative to faculty assessments of communication and physical exam skills. Nonetheless, we recommend that SPs be included in the assessment of communication skills to provide students with comprehensive feedback that more realistically represents the natural patient-provider relationship.

Risk Factors Associated With Nephrotoxicity During Outpatient Intravenous Vancomycin Administration.

Background: Many studies have described an association between intravenous vancomycin and nephrotoxicity; however, the majority have evaluated incidence and risk factors among hospitalized patients. Outpatient administration of intravenous antibiotics is a growing practice and presents its own set of unique challenges. Objective: The aim of this study was to identify risk factors for vancomycin-associated nephrotoxicity in the outpatient setting. Methods: A case-control study of patients who received intravenous vancomycin through an Outpatient Parenteral Antimicrobial Therapy (OPAT) program was conducted. Patients were identified who developed an acute kidney injury (AKI) during treatment. The primary outcome was the incidence of AKI during treatment. Results: A total of 37 out of 130 patients (28.5%) met the criteria for AKI. AKI was more likely to occur in patients with a longer duration of therapy, higher maximum trough concentration, co-administration of a fluoroquinolone or metronidazole, and those who received another potentially nephrotoxic medication. Co-administration of a fluoroquinolone (OR = 5.96, P = 0.009, [CI: 1.59, 24.38]), any nephrotoxic medication (OR = 11.17, P < 0.001, [CI 3.14, 51.23]), and a higher maximum vancomycin trough (OR = 1.29, P < 0.001, [CI 1.17, 1.44]) were all indicative of a higher odds of an AKI. Conclusion: In this cohort, vancomycin-associated nephrotoxicity was common during outpatient intravenous antibiotic therapy. Co-administration of a fluoroquinolone, any nephrotoxic medication, and a higher maximum vancomycin trough were associated with AKI development. Further study is needed to determine how this impacts long-term clinical outcomes and what measures can be taken to reduce nephrotoxicity risk.

Analysis of electrode impedance and its subcomponents for lateral wall, mid-scala, and perimodiolar electrodes in cochlear implants.

OBJECTIVE: Electrode impedances play an important role in cochlear implant patient management. During clinical visits, electrode impedances are calculated from a single point voltage waveform. In the present study, multipoint electrode impedance analysis was performed to study electrode impedance and its subcomponents in patients with three different types of cochlear implant electrode arrays. DESIGN: Voltage waveforms were measured at six different time points during the cathodic phase of a biphasic pulse in forty-seven cochlear implant patients with perimodiolar, mid-scala, or lateral wall electrode arrays. Multipoint electrode impedances were used to determine access resistance and polarization impedance. RESULTS: Access resistance of approximately 5 kΩ was calculated across the three different electrode arrays. Mid-scala electrodes showed a smaller increase in impedances as a function of pulse duration compared to the other electrodes. Patients with lower impedances showed higher capacitance and lower resistance, suggesting that differences in electrochemical reaction at the electrodes' surface can influence impedances in cochlear implants. CONCLUSIONS: Analysis of cochlear implant electrode impedances and their subcomponents provides valuable information about resistance to the flow of current between stimulating and return electrodes, and build an understanding of the contribution of electrochemical processes used to deliver electrical stimulation to the auditory nerve.
