Medical Outcomes of Acute Aspirin Single Substance Poisoning in Pediatric Patients.

BACKGROUND: A consensus guideline on salicylate poisoning recommends referring patients to the emergency department if they ingested 150 mg/kg of aspirin. The dose of aspirin associated with severe poisoning in pediatric patients has not been investigated. OBJECTIVE: This study aims to associate medical outcomes with aspirin overdoses in patients 5 years old and younger. METHODS: A retrospective review of data on pediatric patients with single substance aspirin exposures reported from poison centers across the country was conducted. The primary endpoint was to associate aspirin doses with medical outcomes. Secondary endpoints included evaluation of the signs, symptoms, and treatments of ingestion and their association with medical outcomes. RESULTS: There were 26 488 included exposures with aspirin exposures resulting in no effect (92.5%), minor effect (6.0%), moderate effect (1.4%), major effect (0.2%), and death (0.02%). There were 8921 cases with available weight-based dosing information. Median doses associated with no effect, minor effects, moderate effects, major effects, and death ranged between 28.4 and 40.9 mg/kg, 52.5 and 82.3 mg/kg, 132.1 and 182.3 mg/kg, 132.3 and 172.8 mg/kg, and 142.2 and 284.4 mg/kg, respectively. Minor effect and moderate effect exposures were more likely to have alkalinization documented compared to no effect exposures (odds ratio [OR] = 1.75, 95% confidence interval [CI] = 1.41-2.17; OR = 1.79, 95% CI = 1.12-2.86). There was no difference in rates of alkalinization between minor and moderate exposures (OR = 1.02, 95% CI: 0.61-1.7). CONCLUSIONS AND RELEVANCE: Reevaluation of the current recommendation of 150 mg/kg for referral to a healthcare facility is necessary for pediatric acute salicylate overdoses.

Non-adherence to Labeling Standards Can Misrepresent Safety of Ingredients in Cosmetic Cleansers.

US Labeling requirements for cosmetic products are established by the US Food and Drug Administration (USFDA) and detailed in the Code of Federal Regulations (21 CFR 701.3).1 Over 16,000 cosmetic ingredients names have been documented and ingredient nomenclature resources are recommended by the USFDA for use by manufacturers and suppliers.

Designing better cloth masks: The effect of fabric and attachment-style on discomfort.

Cloth masks are a tool for controlling community transmission during pandemics, as well as during other outbreak situations. However, cloth masks vary in their designs, and the consequences of this variability for their effectiveness as source control have received little attention, particularly in terms of user discomfort and problematic mask-wearing behaviors. In the present studies, common design parameters of cloth masks were systematically varied to ascertain their effect(s) on the subjective discomfort and frequency of problematic mask-wearing behaviors, which detract from the effectiveness of cloth masks as source control. The type of fabric comprising a mask (flannel or twill made of 100% cotton) and the attachment-style of a mask (i.e., ear loops or fabric ties) were varied in adults (18 to 65 years) and children (ages 6 to 11 years). For adults, ear loops were less comfortable than ties (p = .035) and were associated with greater face- (p = .005) and mask-touching (p = .001). Children, however, found flannel masks to be more breathable than twill masks (p = .007) but touched their masks more frequently when wearing a mask made of flannel than twill (p = .033). Common design parameters of cloth masks not only affect user discomfort and behavior but do so differently in adults and children. To improve the effectiveness of cloth masks as source control, the present studies highlight the importance of measuring the effect(s) of design decisions on user discomfort and behavior in different populations.

A method for the tribological assessment of oral pharmaceutical liquids.

OBJECTIVE: Patient acceptance of pediatric formulations is critical to compliance and consequently therapeutic outcomes; thus, having an in vitro method to evaluate sensory perception of pharmaceutical products would be beneficial. The objective of this research is to develop a sensitive and reproducible tribological method to characterize pharmaceutical suspensions at low force and sliding speeds. METHODS: The discriminating potential of the method was examined using tribology profiles (coefficient of friction (COF) vs. sliding speed) for commercially available products and products made for this study with widely varying sweetness, thickness, and grittiness; these formulations were used to judge the sensitivity of the method. Samples were measured using 3M Transpore™ surgical tape to simulate the tongue surface, steel half ring geometry, constant gap setting, target axial force of 2 N in a 600 s exponential ramp for rotation speed. RESULTS: The COF ranged from 0.1 to 0.6. For the speeds studied, the high viscosity commercial suspension ibuprofen drops and acetaminophen suspension show a classic Stribeck curve with an increasing COF at the higher rotation speeds, which indicates these formulations entered the hydrodynamic lubrication phase, while the lower viscosity suspensions only reached the mixed lubrication phase. CONCLUSION: The contribution of particles affects the COF in a dynamic tribologic pattern compared to products that are categorized as either low gritty or high viscosity. These results are important as they provide a potentially rapid in vitro method for screening pediatric medications and help to identify the factors that affect the palatability of pediatric formulations.

Surviving Sepsis Campaign: Guidelines on the Management of Critically Ill Adults with Coronavirus Disease 2019 (COVID-19).

BACKGROUND: The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of a rapidly spreading illness, Coronavirus Disease 2019 (COVID-19), affecting thousands of people around the world. Urgent guidance for clinicians caring for the sickest of these patients is needed. METHODS: We formed a panel of 36 experts from 12 countries. All panel members completed the World Health Organization conflict of interest disclosure form. The panel proposed 53 questions that are relevant to the management of COVID-19 in the ICU. We searched the literature for direct and indirect evidence on the management of COVID-19 in critically ill patients in the ICU. We identified relevant and recent systematic reviews on most questions relating to supportive care. We assessed the certainty in the evidence using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, then generated recommendations based on the balance between benefit and harm, resource and cost implications, equity, and feasibility. Recommendations were either strong or weak, or in the form of best practice recommendations. RESULTS: The Surviving Sepsis Campaign COVID-19 panel issued 54 statements, of which four are best practice statements, nine are strong recommendations, and 35 are weak recommendations. No recommendation was provided for six questions. The topics were: 1) infection control, 2) laboratory diagnosis and specimens, 3) hemodynamic support, 4) ventilatory support, and 5) COVID-19 therapy. CONCLUSION: The Surviving Sepsis Campaign COVID-19 panel issued several recommendations to help support healthcare workers caring for critically ill ICU patients with COVID-19. When available, we will provide new evidence in further releases of these guidelines.

Post-operative non-steroidal anti-inflammatory drug use for pain in infant and paediatric cardiac surgery patients.

BACKGROUND: Pain control is an important element of care for patients after surgery, leading to better outcomes, quicker transitions to recovery, and improvement in quality of life. The purpose of this study was to evaluate the safety and efficacy of non-steroidal anti-inflammatory drugs in children after cardiac surgery. MATERIALS AND METHODS: Patients between the ages of 1 month and 18 years of age, who received intravenous or oral non-steroidal anti-inflammataory drugs after cardiac surgery, from November 2015 until September 2017 were included in this study. The primary endpoints were non-steroidal anti-inflammataory drug-associated renal dysfunction and post-operative bleeding. Secondary endpoints examined the effect of non-steroidal anti-inflammataory drug use on total daily dose of narcotics, number of intravenous PRN narcotic doses received, and pain assessment score. Data were analysed using descriptive statistics for frequencies and ranges. Multivariate analysis was performed to measure the association of all predictors and outcomes. Wilcoxon singed-rank test was performed for secondary outcomes. RESULTS: There was no association between the incidence of renal dysfunction and the use of or duration of non-steroidal anti-inflammataory drugs; in addition no association was found with increased chest tube output. There was a statistically significant reduction of patients' median Face, Legs, Activity, Cry, Consolability (FLACC) scores (2-0; p = 0.003), seen within first 24 hours after initiation of ketorolac, and a significant reduction of morphine requirements seen from day 1 to day 2 (0.3 mg/kg versus 0.1 mg/kg; p < 0.001) and number of as-needed doses. CONCLUSION: Non-steroidal anti-inflammataory drugs in paediatric cardiac surgery patients are safe and effective for post-operative pain management.

Pharmacists and Pediatric Medication Adherence: Bridging the Gap.

Pediatric medication nonadherence is a major problem in the United States health care system. Age of the child, lack of understanding about the disease or treatment, culture, socioeconomic status, family structure, schedule of medications, and taste can all contribute to this problem. Strategies that target interventions to the individual patient and family can be most effective. Pharmacists are at the forefront of patient care and can help children become more adherent to their medications through counseling and building a trusting relationship with the family. This article highlights some common problems to adherence and some solutions to increase adherence.

Validation of the STERIS Amsco 630LS steam sterilizer autoclave for inactivation of category a medical waste from patients with high-consequence infectious diseases.

Hospitals caring for patients with high-consequence pathogens may need to safely manage large volumes of category A waste. Using biological indicators to assess for successful sterilization, autoclave cycle parameters that would inactivate 4 categories of waste were identified and validated utilizing a STERIS Amsco 630LS Steam Sterilizer.

A bacteriophage-based validation of a personal protective equipment doffing procedure to be used with high-consequence pathogens.

OBJECTIVE: To determine if the high-level personal protective equipment used in the treatment of high-consequence infectious diseases is effective at stopping the spread of pathogens to healthcare personnel (HCP) while doffing. BACKGROUND: Personal protective equipment (PPE) is fundamental to the safety of HCPs. HCPs treating patients with high-consequence infectious diseases use several layers of PPE, forming complex protective ensembles. With high-containment PPE, step-by-step procedures are often used for donning and doffing to minimize contamination risk to the HCP, but these procedures are rarely empirically validated and instead rely on following infection prevention best practices. METHODS: A doffing protocol video for a high-containment PPE ensemble was evaluated to determine potential contamination pathways. These potential pathways were tested using fluorescence and genetically marked bacteriophages. RESULTS: The experiments revealed existing protocols permit contamination pathways allowing for transmission of bacteriophages to HCPs. Updates to the doffing protocols were generated based on the discovered contamination pathways. This updated doffing protocol eliminated the movement of viable bacteriophages from the outside of the PPE to the skin of the HCP. CONCLUSIONS: Our results illustrate the need for quantitative, scientific investigations of infection prevention practices, such as doffing PPE.

Efficacy of a Flavored Lubricating Oral Spray on Medication Swallowing in Older Individuals.

Background Difficulty swallowing occurs in up to 35% of patients 50 years of age or older and can contribute to medication nonadherence and other alterations. The use of a flavored lubricating spray, available over-the-counter and found to be helpful in children to swallow oral solid medications, is not well studied in older adults. Objective To evaluate the effect of a flavored lubricating spray on the ability to swallow oral solid medication in older people. Methods A randomized, open-label, crossover study included community-dwelling individuals 65 to 88 years of age who took at least one solid oral medication daily and were not diagnosed with dysphagia, Parkinson's disease, or esophageal tumor. Participants were randomized to the strawberry-flavored lubricating spray or usual care and then crossed over to the alternate option. The median rating for swallowing difficulty for their regular medications was compared using a Likert scale, from 1 (very difficult) to 5 (very easy). To provide a degree of standardization between participants, all participants were also instructed to swallow a vitamin C (1,000 mg) tablet both with and without the flavored spray and rate their difficulty swallowing the tablet using the same Likert scale. Results There were 39 (90.7%) participants who completed the study. The median rating for swallowing difficultly was 5 (very easy) with the spray vs. 4 (easy) with usual care (P < 0.0001). For the 66.7% who took the vitamin C tablets, the median rating for swallowing difficulty was 5 (very easy) with the spray vs. 3.5 (between neutral and easy) without (P < 0.0001). There were 94.8% of participants who found the spray easy/ very easy to use, and 89.7% reported it tasted okay to delicious. Conclusion The use of a flavored lubricating spray provided an effective and easy-to-use tool to make medication swallowing easier in community-dwelling older adults without a diagnosis associated with difficulty swallowing.

Left heart remodelling in hypertensive patients: a comprehensive echocardiography and computed tomography study.

Objectives: This study aimed to assess left heart remodelling changes in hypertension, excluding underlying ischaemic heart disease, utilising computed tomography coronary angiography (CTCA) and transthoracic echocardiography (TTE). Methods: A total of 178 patients (mean age 60 ± 9 years, 53% female) were enrolled in the study: Group 1 consisted of patients with essential hypertension (n = 96, Group 1), and Group 2 served as age-matched controls (n = 82, Group 2). All participants underwent both CTCA and TTE. TTE measurements included left ventricle (LV) concentricity and function and left atrial (LA) volume and function. Using both CTCA and TTE, we measured LV diastasis volume (LVdias) and LA diastasis volume (LAdias). Results: LV mass index and LV mass/height2.7 were similar in both the groups. However, Group 1 had a higher prevalence of concentric LV remodelling, characterised by a larger mean LV wall thickness, increased relative wall thickness ratio, and a reduced ratio of LV end-diastolic volume (LVED) index to mean wall thickness (55 ± 14 vs. 65 ± 15, p = 0.0007). Group 1 showed higher LAdias and LA minimal volumes, while LA reservoir function was lower in Group 2. The LVdias/LAdias ratio was lower in Group 1 compared to Group 2 (TTE 1.77 ± 0.61 vs. 2.24 ± 1.24, p = 0.0025, CTCA 1.50 ± 0.23 vs. 1.69 ± 0.41, p = 0.0002). A composite score based on four combined TTE parameters, namely, LVED index/mean wall thickness ≤57, ratio of early diastolic mitral inflow to mitral annular tissue velocities (E/e') >8, LVdias/LAdias ≤1.62, and LA reservoir function ≤0.58, yielded the highest discriminatory power (area under the curve-AUC = 0.772) for distinguishing patients with hypertensive heart disease (HHD). Collectively, we refer to these parameters as the LEDA score, with each parameter scored as one point. For LEDA scores of 0, 1, 2, 3, 4, the probability of underlying HHD was 0%, 23%, 59%, 80%, and 95%, respectively. Furthermore, a CTCA-derived LVdias/LAdias ≤1.76, considered as a single parameter, demonstrated modest accuracy in differentiating patients with HHD (AUC = 0.646). Conclusions: The TTE LEDA score, based on four parameters, namely, LVED index/mean wall thickness, E/e', LVdias/LAdias, and LA reservoir function, proved to be the most effective in defining left heart remodelling in hypertension.

Understanding Experience of Patients With Highly Infectious Diseases During Extended Isolation: A Design Perspective.

OBJECTIVES: This study aimed to develop a better understanding of the unique needs of patients with highly infectious diseases and their perceptions of being placed in isolation. We explore the subjective experiences of patients treated for Ebola in a biocontainment unit (BCU) and the healthcare personnel who cared for them. BACKGROUND: The 2014 Ebola outbreak and the COVID-19 pandemic have brought to focus some major challenges of caring for patients with serious infectious diseases. Previous studies on BCU design have looked at ways to prevent self- and cross-contamination, but very few have examined how the built environment can support an improved patient experience. METHOD: A qualitative study was conducted with four patients treated for Ebola and two critical care nurses who provided direct care to them at a single BCU in the U.S. Data were collected through in-depth semi-structured interviews to capture the actual patients' perception and experience of isolation. The interviews were analyzed using the thematic analysis approach. RESULTS: The Ebola patients placed in source isolation perceived the BCU as an artificial environment where they lacked control, agency, autonomy, and independence. The physical separation from other patients, visitor restrictions, and staff wearing PPE contributed to feelings of social and emotional isolation, and loneliness. CONCLUSIONS: The isolation can take a toll on physiological and psychological well-being. A thoughtful design of isolation units may improve patients' experience by supporting human and social interactions, empowering patients through space flexibility and personalization of space, and supporting a more holistic approach to isolation care.

Connecting pathogen transmission and healthcare worker cognition: a cognitive task analysis of infection prevention and control practices during simulated patient care.

BACKGROUND: Relatively little is known about the cognitive processes of healthcare workers that mediate between performance-shaping factors (eg, workload, time pressure) and adherence to infection prevention and control (IPC) practices. We taxonomised the cognitive work involved in IPC practices and assessed its role in how pathogens spread. METHODS: Forty-two registered nurses performed patient care tasks in a standardised high-fidelity simulation. Afterwards, participants watched a video of their simulation and described what they were thinking, which we analysed to obtain frequencies of macrocognitive functions (MCFs) in the context of different IPC practices. Performance in the simulation was the frequency at which participants spread harmless surrogates for pathogens (bacteriophages). Using a tertiary split, participants were categorised into a performance group: high, medium or low. To identify associations between the three variables-performance groups, MCFs and IPC practices-we used multiblock discriminant correspondence analysis (MUDICA). RESULTS: MUDICA extracted two factors discriminating between performance groups. Factor 1 captured differences between high and medium performers. High performers monitored the situation for contamination events and mitigated risks by applying formal and informal rules or managing their uncertainty, particularly for sterile technique and cleaning. Medium performers engaged more in future-oriented cognition, anticipating contamination events and planning their workflow, across many IPC practices. Factor 2 distinguished the low performers from the medium and high performers who mitigated risks with informal rules and sacrificed IPC practices when managing tradeoffs, all in the context of minimising cross-contamination from physical touch. CONCLUSIONS: To reduce pathogen transmission, new approaches to training IPC (eg, cognitive skills training) and system design are needed. Interventions should help nurses apply their knowledge of IPC fluidly during patient care, prioritising and monitoring situations for risks and deciding how to mitigate risks. Planning IPC into one's workflow is beneficial but may not account for the unpredictability of patient care.

Pediatric Practitioner Knowledge of Arsenic in Baby Food.

OBJECTIVE: Rice, one of the first solid foods introduced to infants, is 10 times more absorbent of inorganic arsenic than any other grain. An evaluation has not been performed about practitioner knowledge of arsenic content in infant foods. The purpose of this survey was to determine pediatric practitioners' knowledge of current US Food and Drug Administration (FDA) recommendations to limit exposure to arsenic-containing foods in infants. METHODS: This was a convenience sample of pediatric practitioners conducted as an online survey. The survey contained 19 questions related to knowledge of arsenic-containing foods, FDA recommendations, practitioner recommendations on feeding infants, and demographic information. Participants were recruited using organization list servs. Participants were reminded to complete the survey 2 months after the initial email. An infographic on arsenic was provided at the end of the survey. RESULTS: One hundred thirty-seven individuals completed the survey. The majority of respondents were physicians or pharmacists and have been in practice less than 6 years. Nine percent of respondents (11/123) stated the FDA arsenic limit of 100 ppb. Sixteen percent (20/123) identified white rice as having a lower inorganic arsenic content than brown rice and 27% (36/132) identified that there is no difference in inorganic arsenic content between organic infant rice cereal and conventional infant rice cereal. CONCLUSIONS: The vast majority of participants were not aware of the FDA's proposed limit on arsenic consumption or the concern of heavy metals in baby foods. More education is needed to increase knowledge regarding arsenic in baby foods.

Development and validation of the discomfort of cloth Masks-12 (DCM-12) scale.

During the COVID-19 pandemic, the use of face masks by the public has helped to slow the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the community. Cloth masks have been recommended because of their effectiveness, availability, and reusability. Like other types of face masks, however, user discomfort while wearing cloth masks is thought to engender behaviors that limit the effectiveness of cloth masks as source control (e.g., adjusting or removing one's mask temporarily while in public). To design cloth masks that are more tolerable, a measurement instrument for assessing subjective user discomfort is needed. Across two studies, we identified and confirmed a two-dimensional factor structure underlying the discomfort of cloth masks - discomfort related to the breathability and discomfort related to the tightness of the mask against the face and head. Additionally, we provide replicable evidence that both factor-subscales predict the self-reported frequencies of problematic mask-wearing behaviors.

Healthcare design to improve safe doffing of personal protective equipment for care of patients with COVID-19.

OBJECTIVE: Understand how the built environment can affect safety and efficiency outcomes during doffing of personal protective equipment (PPE) in the context of coronavirus disease 2019 (COVID-19) patient care. STUDY DESIGN: We conducted (1) field observations and surveys administered to healthcare workers (HCWs) performing PPE doffing, (2) focus groups with HCWs and infection prevention experts, and (3) a with healthcare design experts. SETTINGS: This study was conducted in 4 inpatient units treating patients with COVID-19, in 3 hospitals of a single healthcare system. PARTICIPANTS: The study included 24 nurses, 2 physicians, 1 respiratory therapist, and 2 infection preventionists. RESULTS: The doffing task sequence and the layout of doffing spaces varied considerably across sites, with field observations showing most doffing tasks occurring around the patient room door and PPE support stations. Behaviors perceived as most risky included touching contaminated items and inadequate hand hygiene. Doffing space layout and types of PPE storage and work surfaces were often associated with inadequate cleaning and improper storage of PPE. Focus groups and the design charrette provided insights on how design affording standardization, accessibility, and flexibility can support PPE doffing safety and efficiency in this context. CONCLUSIONS: There is a need to define, organize and standardize PPE doffing spaces in healthcare settings and to understand the environmental implications of COVID-19-specific issues related to supply shortage and staff workload. Low-effort and low-cost design adaptations of the layout and design of PPE doffing spaces may improve HCW safety and efficiency in existing healthcare facilities.

Healthcare worker mental models of patient care tasks in the context of infection prevention and control.

OBJECTIVE: Understanding the cognitive determinants of healthcare worker (HCW) behavior is important for improving the use of infection prevention and control (IPC) practices. Given a patient requiring only standard precautions, we examined the dimensions along which different populations of HCWs cognitively organize patient care tasks (ie, their mental models). DESIGN: HCWs read a description of a patient and then rated the similarities of 25 patient care tasks from an infection prevention perspective. Using multidimensional scaling, we identified the dimensions (ie, characteristics of tasks) underlying these ratings and the salience of each dimension to HCWs. SETTING: Adult inpatient hospitals across an academic hospital network. PARTICIPANTS: In total, 40 HCWs, comprising infection preventionists and nurses from intensive care units, emergency departments, and medical-surgical floors rated the similarity of tasks. To identify the meaning of each dimension, another 6 nurses rated each task in terms of specific characteristics of tasks. RESULTS: Each HCW population perceived patient care tasks to vary along 3 common dimensions; most salient was the perceived magnitude of infection risk to the patient in a task, followed by the perceived dirtiness and risk of HCW exposure to body fluids, and lastly, the relative importance of a task for preventing versus controlling an infection in a patient. CONCLUSIONS: For a patient requiring only standard precautions, different populations of HCWs have similar mental models of how various patient care tasks relate to IPC. Techniques for eliciting mental models open new avenues for understanding and ultimately modifying the cognitive determinants of IPC behaviors.

Performance of Verigene Rapid Diagnostic Testing for Detection of Inpatient Pediatric Bacteremia.

OBJECTIVE: Verigene blood culture panels comprise rapid diagnostic testing, which aids in early bacteremia species identification. This study determined the concordance of Verigene rapid diagnostic results compared with the Vitek reference standard in patients admitted to a children's hospital. METHODS: This was a 3-year retrospective observational study of neonatal and pediatric patients ≤18 years admitted to a children's hospital with confirmed bacteremia for whom Verigene testing was performed. Verigene testing was conducted on cultures with reported growth on Gram stain and final organism speciation confirmed via Vitek. Percent concordance and positive percent agreement with 95% CIs were calculated for Verigene panel-identifiable organisms. Negative percent agreement with 95% CIs was calculated for non-panel organisms. Time-to-result was calculated from Gram stain reporting to both Verigene and Vitek final organism susceptibility. RESULTS: One hundred thirty-five Gram-positive (GP) and 51 Gram-negative (GN) isolates were identified through Vitek. Verigene GP panel-detectable organisms were correctly identified 96.9% (125/129) at the genus level and 95.3% (123/129) at the species level. Overall positive percent agreement was 95.3 (CI: 90.2-98.3). Negative percent agreement was 83.3 (CI: 35.9-99.6) for the 6 non-panel GP organisms. All GN isolates were correctly identified on Verigene. Median time-to-result was 2.9 hours (IQR 2.6, 3.2) and 44.4 hours (IQR: 35.4, 52.5) for Verigene and final susceptibilities, respectively. There was a statistically significant time savings of 41.5 hours (CI: 29.8-53.2) for identification and detection of resistance markers (p < 0.0001). CONCLUSION: Verigene concordance at our institution aligns with results from previously published studies and can be considered a reliable clinical decision-support tool.
