Characterizing Utilization and Outcomes of Digoxin Immune Fab for Digoxin Toxicity.

BACKGROUND: Digoxin is a widely prescribed drug for congestive heart failure and atrial fibrillation. Digoxin has a narrow therapeutic index and toxicity can develop quite easily. Digoxin immune fab (DIF) is an effective treatment for toxicity, however there are limited studies characterizing its impact on clinical outcomes in real-world clinical practice. OBJECTIVES: The aim of this study was to identify factors and healthcare outcomes associated with digoxin immune fab (DIF) treatment in patients with confirmed/suspected digoxin toxicity. METHODS: An IRB-approved retrospective chart review of digoxin toxic patients (2011-2020) presenting at an academic healthcare system was conducted. Demographic and clinical data were collected. Patients were stratified by DIF treatment versus non-DIF treatment. DIF utilization patterns (appropriate, use when not indicated, or underutilized) were determined using pre-defined criteria. Severe digoxin toxicity was defined as having one or more of the following: mental status disturbances, antiarrhythmic therapy, acute renal impairment or dehydration, serum digoxin concentration (SDC) > 4 ng/mL, or serum K+ > 5 mEq/mL. Logistic multivariable regression analysis evaluated factors associated with DIF use. All statistical analyses were performed in R version 4.1. RESULTS: Data from 96 patients (non-DIF treated group = 49; DIF treated group = 47) were analyzed. DIF was used appropriately in 70 patients (73%), underutilized in 19 (20%), and administered to 7 (7%) patients when it was not indicated. Several clinical parameters differentiated the DIF from the non-DIF group (p < 0.05) including higher mean SDC (3.41 ± 1.63 vs 2.87 ± 1.17), higher mean potassium (5.33 ± 1.48 vs 4.55 ± 0.87), more toxicity severity (85% vs 49%), and more likely to require cardiac pacing (26% vs 4%). Digoxin toxicity resolved sooner in the DIF group (coefficient - 0.702, 95% CI - 1.137 to - 0.267) (p < 0.01) and they had shorter intensive care unit lengths of stay (12.4 ± 20.3 vs 24.4 ± 28.7 days; p = 0.018). The all-cause mortality rate in patients appropriately managed with DIF therapy versus those patients where DIF was underutilized was 11% and 21%, respectively. CONCLUSIONS: Based on our study population, DIF therapy appears to be beneficial in limiting duration of toxicity and intensive care unit lengths of stay in digoxin toxic patients. Although DIF was appropriately utilized in most cases, there was a relatively high proportion of cases in which DIF treatment was either underutilized or not indicated.

Early Administration of Steroids in the Ambulance Setting: An Observational Design Trial (EASI-AS-ODT).

BACKGROUND: In the emergency department (ED), prompt administration of systemic corticosteroids for pediatric asthma exacerbations decreases hospital admission rates. However, there is sparse evidence for whether earlier administration of systemic corticosteroids by emergency medical services (EMS) clinicians, prior to ED arrival, further improves pediatric asthma outcomes. METHODS: Early Administration of Steroids in the Ambulance Setting: An Observational Design Trial is a multicenter, observational, nonrandomized stepped-wedge design study with seven participating EMS agencies who adopted an oral systemic corticosteroid (OCS) into their protocols for pediatric asthma treatment. Using univariate analyses and multivariable mixed-effects models, we compared hospital admission rates for pediatric asthma patients ages 2-18 years before and after the introduction of a prehospital OCS and for those who did and did not receive a systemic corticosteroid from EMS. RESULTS: A total of 834 patients were included, 21% of whom received a systemic corticosteroid from EMS. EMS administration of systemic corticosteroids increased after the introduction of an OCS from 14.7% to 28.1% (p < 0.001). However, there was no significant difference between hospital admission rates and ED length of stay before and after the introduction of OCS or between patients who did and did not receive a systemic corticosteroid from EMS. Mixed-effects models revealed that age 14-18 years (coefficient -0.83, p = 0.002), EMS administration of magnesium (coefficient 1.22, p = 0.04), and initial EMS respiratory severity score (coefficient 0.40, p < 0.001) were significantly associated with hospital admission. CONCLUSIONS: In this multicenter study, the addition of an OCS into EMS agency protocols for pediatric asthma exacerbations significantly increased systemic corticosteroid administration but did not significantly decrease hospital admission rates. As overall EMS systemic corticosteroid administration rates were low, further work is required to understand optimal implementation of EMS protocol changes to better assess potential benefits to patients.

Prehospital Pediatric Asthma Care during COVID-19: Changes to EMS Treatment Protocols and Downstream Clinical Effects.

INTRODUCTION: During the COVID-19 pandemic, many emergency medical services (EMS) agencies modified treatment guidelines for clinical care and standard operating procedures. For the prehospital care of pediatric asthma exacerbations, modifications included changes to bronchodilator administration, systemic corticosteroid administration, and introduction of alternative medications. Since timely administration of bronchodilators and systemic corticosteroids has been shown to improve pediatric asthma clinical outcomes, we investigated the association of COVID-19 protocol modifications in the prehospital management of pediatric asthma on hospital admission rates and emergency department (ED) length-of-stay. METHODS: This is a multicenter, retrospective, observational cohort study comparing prehospital pediatric asthma patients treated by EMS clinicians from four EMS systems before and after implementation of COVID-19 interim EMS protocol modifications. We included children ages 2-18 years who were treated and transported by ground EMS for respiratory-related prehospital primary complaints, and who also had asthma-related ED discharge diagnoses. Patient data and outcomes were compared from 12 months prior to and 12 months after the implementation of interim COVID-19 prehospital protocol modifications using univariate and multivariable statistics. RESULTS: A total of 430 patients met inclusion criteria with a median age of 8 years. There was a slight male predominance (57.9%) and the majority of patients were African American (78.4%). There were twice as many patients treated prior to the COVID-19 protocol modifications (N = 287) compared to after (N = 143). There was a significant decrease in EMS bronchodilator administration from 76% to 59.4% of patients after COVID-19 protocol guidelines were implemented (p < 0.0001). Mixed effects models for hospital admission (to both pediatric inpatient units and pediatric intensive care units) as well as ED length-of-stay did not show any significant effect after the COVID-19 protocol change period (p = 0.18 and p = 0.55, respectively). CONCLUSIONS: Despite a decrease in prehospital bronchodilator administration after COVID-19 changes to prehospital pediatric asthma management protocols, hospital admission rates and ED length-of-stay did not significantly increase. However, this finding is tempered by the marked decrease in study patients treated after COVID-19 prehospital protocol modifications. Given the potential for future waves of COVID-19 variants, further studies with larger patient populations are warranted.

Exploration of Relationships among Clinical Gastrointestinal Indicators and Social and Sensory Symptom Severity in Children with Autism Spectrum Disorder.

Autism Spectrum Disorders (ASD) are associated with co-morbidities such as gastrointestinal (GI) symptomatology, which in the absence of known causes are potential indicators of gut microbiota that may influence behavior. This study's purpose was to explore relationships among clinical GI indicators-diet, abdominal pain, and stool status-and ASD symptom severity, specifically social and sensory symptoms. Participants were 33 children with ASD, 3 to 16 years. The Social Responsiveness Scale (SRS-2) and the Child Sensory Profile Scale (CSP-2) were used to appraise social and sensory symptomatology. Significant difference was found in overall SRS-2, t(31) = -3.220, p = 0.003 when compared by abdominal pain status using independent samples t-tests. Significant difference was observed for overall CSP-2, t(31) = -2.441, p = 0.021, when grouped by stool. The three clinical GI variables predicted overall SRS-2 score using multiple linear regression, F(3, 32) = 3.257, p = 0.036; coefficient for abdominal pain significantly contributed to the outcome. Findings contribute to the growing literature signaling the need to understand occurrence of GI symptomatology more deeply, and in consideration of diet status and its implications in the children's everyday lives, behaviors, and symptom severity.

Clinical Course of Motor Deficits from Lumbosacral Radiculopathy Due to Disk Herniation.

BACKGROUND: The clinical course of motor deficits from lumbosacral radiculopathy appears to improve with or without surgery. Strength measurements have been confined to manual muscle testing (MMT) and have not been extensively followed and quantified in prior studies. OBJECTIVE: To determine if motor weakness and patient-reported outcomes related to lumbosacral radiculopathy improve without surgical intervention over the course of 12 months. DESIGN: Prospective observational cohort. SETTING: Outpatient academic spine practice. PARTICIPANTS: Adults with acute radicular weakness due to disk herniation. METHODS: Forty patients with radiculopathy and strength deficit were followed over a 12-month period. Objective strength and performance tests as well as survey-based measurements were collected at baseline and then every 3 months. Patients underwent comprehensive pain management and rehabilitation and/or surgical approaches as determined in coordination with the treating specialist. This study was approved by the institutional review board of Colorado. MAIN OUTCOME MEASUREMENTS: Testing of strength was through MMT, handheld dynamometer, and performance-based testing. Furthermore, visual analog scale, modified Oswestry Disability Index, and 36-Item Short Form Health Survey (SF-36) were used to measure pain and disability outcomes. RESULTS: Of the 40 patients, 33 (82.5%) did not have surgery; 7 (17.5%) had surgery. Twenty-four of the 33 patients (60%) did not undergo surgery and were followed for 12 months (Comprehensive Pain Management and Rehabilitation, Complete [CPM&R-C]), and 9 (22%) did not have surgery and lacked at least one follow-up evaluation (Comprehensive Pain Management and Rehabilitation, Incomplete [CPM&R-I]). No statistically significant differences were found on baseline measures of strength deficits and SF-36 domains between the CPM&R-C, Surgery, and CPM&R-I groups. Pain and disability scores in the Surgery group were significantly higher than in the CPM&R-C at baseline. There were statistically significant improvements in all areas of strength, pain, and function when comparing measurements at the 12-month follow-up to baseline in the CPM&R-C group. CONCLUSIONS: Individuals with motor deficits due to lumbosacral radiculopathy improve over time regardless of treatment choice. Most did not choose surgery, and almost all of these patients regained full strength at 1 year. Strength recovery typically occurred in the first 3 months, but there was ongoing recovery over the course of a year. LEVEL OF EVIDENCE: II.

Developing and Testing the Short-Form Knowledge, Efficacy, and Practices Instrument for Assessing Cultural Competence.

The importance of educating dental students in cultural competence has been widely emphasized, but there is a need to assess cultural competence in a consistent and reliable way. The aims of this study were to determine latent constructs for the initial measure of cultural competence for oral health providers, the Knowledge, Efficacy, and Practices Instrument (KEPI), and to determine how well these factors related to previously identified latent constructs. Data were collected in surveys of dental students and from dental hygiene, dental assisting, and dental faculty members in 44 academic dental institutions from 2012 to 2015. There were a total of 1,786 respondents to the surveys; response rates to individual surveys ranged from 35% to 100%. There were 982 (55%) female and 804 (45%) male respondents, 286 (16%) underrepresented minority (URM) and 1,500 (84%) non-URM respondents, and 339 (19%) faculty and 1,447 (81%) student respondents. Three latent constructs were identified. Female respondents scored significantly higher on the culture-centered practice and efficacy of assessment factors, while URM respondents had significantly higher scores on all three of the KEPI factors. Measurements indicated that the long-form KEPI could be shortened by ten questions and still have three meaningful measurements. Continued research in assessing other health care providers' cultural competence is needed to expand the KEPI to measure providers' cultural competence with patients with minority sexual orientation and gender identity issues and those with physical disabilities, mental illness, and autism to advance patient-centric communication.

Risk Factors for Urosepsis in Older Adults: A Systematic Review.

Objective: To identify factors that predispose older adults to urosepsis and urosepsis-related mortality. Method: A systematic search using PubMed and CINAHL databases. Articles that met inclusion criteria were assessed using the Strengthening the Reporting of OBservational studies in Epidemiology (STROBE) criteria and were scored on a 4-point Likert-type scale. Results: A total of 180 articles were identified, and six met inclusion criteria. The presence of an internal urinary catheter was associated with the development of urosepsis and septic shock. Although a number of factors were examined, functional dependency, number of comorbidities, and low serum albumin were associated with mortality across multiple studies included in this review. Discussion: Little scientific evidence is available on urosepsis, its associated risk factors, and those factors associated with urosepsis-related mortality in older adults. More research is warranted to better understand urosepsis in this vulnerable population in an effort to improve the quality of patient care.
