The impact of month and season on the incidence of giant cell arteritis: an Intelligent Research in Sight (IRIS) Registry analysis.

PURPOSE: Previous investigations into the relationship between season and the incidence of giant cell arteritis (GCA) have produced conflicting results. This study aimed to explore the impact of season and new diagnoses of GCA in a more definitive sense by employing the large dataset of the Intelligent Research in Sight (IRIS) database. METHODS: The IRIS Registry was queried to identify new cases of GCA from 2013 to 2021. Statistical analyses were performed to determine the significance of the relationship between the time of year and the incidence of GCA on regional and nationwide bases via Cochran's Q statistical test. RESULTS: A total of 27,339 eyes with a new diagnosis of GCA were identified. Neither the month nor the season of the year correlated with the incidence of GCA, regardless of geographic location within the USA (p > 0.05 for each variable). CONCLUSIONS: In the USA, the incidence of GCA does not appear to vary by month or season. While this finding contradicts certain previous studies that identified a relationship, the cohort of patients identified from the IRIS Registry is much larger than that of previous investigations. Clinicians should be mindful of the possibility of GCA, regardless of the time of the year.

Developing a Novel Interactive Colorectal Cancer Educational Session for First-Year Medical Students to Enhance Interest in Public Health.

Medical students need more exposure to and a greater understanding of their role in public health throughout their training, which may influence more of them to pursue careers in public health or change how they practice medicine in the future. A novel colorectal cancer education session was created for first year medical students to attempt to increase public health interest, improve colorectal cancer knowledge and discuss barriers to colorectal cancer screening. We constructed a novel integrated interactive peer led colorectal cancer educational session of panelists with a wide range of experiences in colorectal cancer and colorectal cancer screening. The session involved a didactic component, case presentation, and group exercises followed by assembly discussion. We surveyed first-year medical students over two consecutive years to assess their interest in public health, knowledge of colorectal cancer, and perceptions of barriers to colorectal cancer screening before and after the educational session. We also evaluated student satisfaction with the session. We compared the pre- and post-survey results to assess for changes in interest, knowledge and perceptions. 74.63% of students in 2018 and 67.7% in 2019 evaluated the session as excellent or good, with knowledge regarding colorectal cancer screening markedly increased after the educational session. Students reported knowledge and access to healthcare among the biggest patient barriers to colorectal cancer screening. Interest in public health increased by 7.5% and 5.6% in 2018 and 2019, respectively. The implementation of this interactive educational peer led exercise can increase interest in public health, improve knowledge of colorectal cancer prevention and facilitate discussions of colorectal cancer screening barriers. We hope to encourage other programs to adopt this preliminary model.

Patients' Perspectives on Emergency Department COVID-19 Vaccination and Vaccination Messaging Through Randomized Vignettes.

OBJECTIVES: Emergency departments (EDs) could play an important role in the COVID-19 pandemic response by reaching patients who would otherwise not seek vaccination in the community. Prior to expanding COVID-19 vaccination to the acute care setting, we assessed ED patients' COVID-19 vaccine status, perspectives, and hypothetical receptivity to ED-based vaccination. METHODS: From January 11 through March 31, 2021, we conducted a multisite (Albany Medical Center, Boston Medical Center, Buffalo General Hospital, University of Cincinnati Medical Center, and Upstate Medical Center), cross-sectional survey of ED patients, with embedded randomization for participants to receive 1 of 4 vignette vaccination messages (simple opt-in message, recommendation by the hospital, community-oriented message, and acknowledgment of vaccine hesitancy). Main outcomes included COVID-19 vaccination status, prior intention to be vaccinated, and receptivity to randomized hypothetical vignette messages. RESULTS: Of 610 participants, 122 (20.0%) were vaccinated, 234 (38.4%) had prior intent to be vaccinated, 111 (18.2%) were unsure as to prior intent, and 143 (23.4%) had no prior intent to be vaccinated. Vaccine hesitancy (participants who were vaccine unsure or did not intend to receive the vaccine) was associated with the following: age <45 years, female, non-Hispanic Black, no primary health care, and no prior influenza vaccination. Overall, 364 of 565 (64.4%; 95% CI, 60.3%-68.4%) were willing to accept a hypothetical vaccination in the ED. Among participants with prior vaccine hesitancy, a simple opt-in message resulted in the highest acceptance rates to hypothetical vaccination (39.7%; 95% CI, 27.6%-52.8%). CONCLUSIONS: EDs have appropriate patient populations to initiate COVID-19 vaccination programs as a supplement to community efforts. A simple opt-in approach may offer the best messaging to reach vaccine-hesitant ED patients.

COVID-19 and beyond: Lessons learned from emergency department HIV screening for population-based screening in healthcare settings.

Emergency departments (EDs) have played a major role in the science and practice of HIV population screening. After decades of experience, EDs have demonstrated the capacity to provide testing and linkage to care to large volumes of patients, particularly those who do not otherwise engage the healthcare system. Efforts to expand ED HIV screening in the United States have been accelerated by a collaborative national network of emergency physicians and other stakeholders called EMTIDE (Emergency Medicine Transmissible Infectious Diseases and Epidemics). As the COVID-19 pandemic evolves, EDs nationwide are being tasked with diagnosing and managing COVID-19 in a myriad of capacities, adopting varied approaches based in part on know-how, local disease trends, and the supply chain. The objective of this article is to broadly summarize the lessons learned from decades of ED HIV screening and provide guidance for many analogous issues and challenges in population screening for COVID-19. Over time, and with the accumulated experience from other epidemics, ED screening should develop into an overarching discipline in which the disease in question may vary, but the efficiency of response is increased by prior knowledge and understanding.

Lack of active SARS-CoV-2 virus in a subset of PCR-positive COVID-19 congregate care patients.

Highly sensitive nucleic acid amplification tests (NAATs) designed to detect SARS-CoV-2 RNA are the standard of care for the diagnosis of COVID-19. However, the accuracy of these methods for the quantitation of active virus rather than non-infectious RNA fragments that can persist for extended periods of time has been unclear. This issue is particularly relevant for congregate care patients who are unable to return to their home residence until fully negative by NAATs. We tested paired samples from individual patients for the presence of virus at both early and later stages of disease. Culture of nasopharyngeal swab samples for 10 days in Vero E6 cells revealed active virus in only 4 out of 14 (28.6%) patients. The ability to isolate viral plaque-forming units (PFU) correlated with viral RNA loads of >6.79 log genomic copies/ml and only occurred in samples collected from patients early after symptom onset and before development of antibody. Culture in Vero E6 cells lacking the STAT1-dependent interferon signaling pathway increased the numbers of viral PFU detected but did not affect the incidence of positive cultures. We conclude that culturable virus is correlated with SARS-CoV-2 NAATs detection only during early symptom onset and with high viral titers/low antibody titers in non-immunosuppressed patients.

Compliance with American College of Chest Physicians (ACCP) recommendations for thromboembolic prophylaxis in the intensive care unit: a level I trauma center experience.

BACKGROUND: Recommendations are for nearly universal venous thromboembolism (VTE) prophylaxis in critically ill hospitalized patients because of their well-recognized risks. In those intensive care units (ICUs) where patient care is more uniformly directed, it may be expected that VTE prophylaxis would more closely follow this standard over units that are less uniform, such as open-model ICUs. METHODS: This was a retrospective cohort study on all patients aged 18+ admitted to an open ICU between 6/1/2017 and 5/31/2018. Patients were excluded if they had instructions to receive comfort measures only or required therapeutic anticoagulant administration. Prophylaxis administration practices, including administration of mechanical and/or pharmacologic prophylaxis and delayed (≥48 h post-ICU admission) initiation of pharmacologic prophylaxis, were compared between patients admitted to the ICU by the trauma service versus other departments. Root causes for opting out of pharmacological prophylaxis were documented and compared between the two study groups. RESULTS: One-hundred two study participants were admitted by the trauma service, and 98 were from a non-trauma service. Mechanical (98% trauma vs. 99% non-trauma, P = 0.99) and pharmacologic (54% vs. 44%, P = 0.16) prophylaxis rates were similar between the two admission groups. The median time from ICU admission to pharmacologic prophylaxis initiation was 53 h for the trauma service and 10 h for the non-trauma services (P ≤ 0.01). In regression analyses, trauma-service admission (odds ratio (OR) = 2.88, 95% confidence interval (CI) 1.21-6.83) and increasing ICU length of stay (OR = 1.13, 95% CI 1.05-1.21) were independently associated with pharmacologic prophylaxis use. Trauma-service admission (OR = 8.30, 95% CI 2.18-31.56) and increasing hospital length of stay (OR = 1.15, 95% CI 1.03-1.28) were independently associated with delayed prophylaxis initiation. CONCLUSIONS: Overall, the receipt of VTE prophylaxis of any type was close to 100%, due to the nearly universal use of mechanical compression devices among ICU patients in this study. However, when examining pharmacologic prophylaxis specifically, the rate was considerably lower than is currently recommended: 54% among the trauma services and 44% among non-trauma services.

Basic Life Support Awareness and Knowledge in High School Students.

INTRODUCTION: Cardiovascular disease is the leading cause of death in the United States. When cardiovascular disease results in cardiac arrest, the ability to perform basic life support (BLS) can change the outcome from death to survival. There is no definitive statistical data on high schoolers' awareness of basic life support (BLS). METHODS: A survey-based research study was conducted to find high schoolers' awareness of BLS. A total of 105 students, primarily from Kansas City suburbs, took a survey with questions ranging from their views on whether BLS courses should be integrated into the high school curriculum to the steps they would take when a person collapses on the ground. Results were analyzed to determine the students' knowledge of different aspects of BLS and their interest in taking a BLS course in school. RESULTS: Over 70% of the students would take a BLS course should it be offered in a high school class. Most students answered questions regarding BLS steps correctly but lacked critical knowledge on an automated external defibrillator (AED). CONCLUSIONS: Although over 70% of the students were aware of the basics of BLS, most students lacked knowledge on the critical aspects of BLS, such as the use of an AED. Most students recognize the importance of BLS in the high school curriculum and would acquire the skills in a high school class. Introducing a BLS course in the high school curriculum would improve the students' knowledge and contribute to improved survival rates of victims of out-of-hospital cardiac arrest.

Evaluation of Specimen Types and Saliva Stabilization Solutions for SARS-CoV-2 Testing.

Identifying SARS-CoV-2 infections through aggressive diagnostic testing remains critical to tracking and curbing the spread of the COVID-19 pandemic. Collection of nasopharyngeal swabs (NPS), the preferred sample type for SARS-CoV-2 detection, has become difficult due to the dramatic increase in testing and consequent supply strain. Therefore, alternative specimen types have been investigated that provide similar detection sensitivity with reduced health care exposure and the potential for self-collection. In this study, the detection sensitivity of SARS-CoV-2 in nasal swabs (NS) and saliva was compared to that of NPS using matched specimens from two outpatient cohorts in New York State (total n = 463). The first cohort showed only a 5.4% positivity, but the second cohort (n = 227) had a positivity rate of 41%, with sensitivity in NPS, NS, and saliva of 97.9%, 87.1%, and 87.1%, respectively. Whether the reduced sensitivity of NS or saliva is acceptable must be assessed in the settings where they are used. However, we sought to improve on it by validating a method to mix the two sample types, as the combination of nasal swab and saliva resulted in 94.6% SARS-CoV-2 detection sensitivity. Spiking experiments showed that combining them did not adversely affect the detection sensitivity in either. Virus stability in saliva was also investigated, with and without the addition of commercially available stabilizing solutions. The virus was stable in saliva at both 4°C and room temperature for up to 7 days. The addition of stabilizing solutions did not enhance stability and, in some situations, reduced detectable virus levels.

Effects of propofol on ischemia-reperfusion and traumatic brain injury.

Oxidative stress exacerbates brain damage following ischemia-reperfusion and traumatic brain injury (TBI). Management of TBI and critically ill patients commonly involves use of propofol, a sedation medication that acts as a general anesthetic with inherent antioxidant properties. Here we review available evidence from animal model systems and clinical studies that propofol protects against ischemia-reperfusion injury. However, evidence of propofol toxicity in humans exists and manifests as a rare complication, "propofol infusion syndrome" (PRIS). Evidence in animal models suggests that brain injury induces expression of the p75 neurotrophin receptor (p75NTR), which is associated with proapoptotic signaling. p75NTR-mediated apoptosis of neurons is further exacerbated by propofol's superinduction of p75NTR and concomitant inhibition of neurotrophin processing. Propofol is toxic to neurons but not astrocytes, a type of glial cell. Evidence suggests that propofol protects astrocytes from oxidative stress and stimulates astroglial-mediated protection of neurons. One may speculate that in brain injury patients under sedation/anesthesia, propofol provides brain tissue protection or aids in recovery by enhancing astrocyte function. Nevertheless, our understanding of neurologic recovery versus long-term neurological sequelae leading to neurodegeneration is poor, and it is also conceivable that propofol plays a partial as yet unrecognized role in long-term impairment of the injured brain.

Barriers to Healthcare for People Who Inject Drugs: A Survey at a Syringe Exchange Program.

Objective: Despite research demonstrating increased need for healthcare services among people who use drugs, few studies have investigated barriers to general healthcare in this population. We explored the most common barriers to general healthcare faced by clients utilizing syringe access services. Methods: Clients of Project Safe Point- a syringe access service serving Albany, NY and surrounding regions-were surveyed on their general health practices and specific health care barriers. Descriptive analyses were used to identify which barriers were most prevalent. Results: Of the clients surveyed (n = 59), the most common specific barriers were deprioritization of medical care (i.e., procrastination [80%], finding it easier to ignore the problem [63%]), cost (i.e., not having insurance [59%], not being able to afford the cost of care [58%]), transportation (53%), and judgement by clinicians (53%). When participants were asked to choose which was their biggest barrier to healthcare, judgement by clinicians was chosen more than twice as often as any other barrier. Conclusion: While people who inject drugs at a syringe access program often experience traditional barriers to healthcare (i.e., logistical barriers, procrastination), nearly a quarter of the clients reported feeling judged by clinicians as their most significant barrier. Future work in this field should explore interventions that motivate clients to seek care and that reduce stigma in healthcare interactions.

The effect of discharge destination and primary insurance provider on hospital discharge delays among patients with traumatic brain injury: a multicenter study of 1,543 patients.

BACKGROUND: Hospital length of stay (HLOS) is a commonly used measure of hospital quality and is influenced by clinical and non-clinical factors. To reduce HLOS, it is key to identify factors placing patients at increased risk of lengthy HLOS and discharge delays. METHODS: This was a retrospective cohort study of patients age ≥ 18 admitted to four level 1 trauma centers between 1/1/2015 and 3/31/2018 with traumatic brain injury (TBI). The primary outcome was discharge delay, defined as discharge ≥24 h after case management notes indicated the patient was ready for discharge. The independent variables of interest were primary insurance provider and discharge destination. Chi-square, Fisher exact, and unadjusted and adjusted logistic regression analyses were used to assess associations between discharge delay and the two primary independent variables, as well as other patient demographic and clinical characteristics. Complications developing during the delay period were also examined. RESULTS: A total of 1543 patients with TBI were included. The median age was 61 years, and the median HLOS was 5 days. Approximately half of patients were discharged home (54%). The most common insurance providers were Medicare (35%) and commercial/private (35%). Two-hundred ten (14%) patients experienced a discharge delay. The median delay period was 3 days, and the most common reasons for delay were insurance authorization (52%) and lack of accepting bed (41%). Compared to being discharged home, patients discharged to a skilled nursing facility (adjusted odds ratio (AOR) = 10.35) or intermediate care facility (AOR = 10.64) had the highest odds of discharge delay. Compared to Medicare patients, uninsured/self-pay patients (AOR = 2.98) and those with Medicaid (AOR = 2.83) or commercial/private insurance (AOR = 2.22) had higher odds of delay. Thirty-two patients (15% of those delayed) experienced at least one complication during the delay, some of which were clinically severe. CONCLUSIONS: A substantial portion of TBI patients in this study experienced discharge delays, and discharge destination and primary insurance provider were significant drivers of these delays. Evaluation of a facility's quality of care should consider the specific causes of these delays.

The presence of S-sulfonated transthyretin in commercial human serum albumin solutions: Potential contribution to neuropathy.

BACKGROUND: Commercial solutions of human serum albumin (HSA) are administered to critically ill patients for the treatment of shock, restoration of blood volume, and the acute management of burns. Previously, conflicting results on the effects of HSA administration have been reported varying from a favorable increase in total plasma antioxidant capacity to a higher mortality rate in traumatic brain injury (TBI) patients. These results could be partially explained due to the known heterogeneity of HSA solutions. We report the discovery of S-sulfonated human transthyretin (hTTR) in HSA solutions. METHODS: Proteomics was performed on commercially available solutions of 5% HSA by LC-MS analysis. The MS charge envelope for hTTR was deconvolved to the uncharged native hTTR parent mass (13,762 Da). The parent mass was then integrated, and relative proportions of the 2 major species of hTTR, native and S-sulfonated hTTR (13,842 Da), were calculated. RESULTS: The majority of hTTR found in 5% commercial HSA solutions is in the S-sulfonated form regardless of the age of the HSA solution. S-sulfonation of hTTR at the free cysteine residue in position 10 appears to be the result of a mixed disulfide exchange possibly with S-cysteinylated hTTR or S-cysteinylated HSA. hTTR is a tetramer composed of four identical monomers each containing a reduced cysteine residue in position 10. S-sulfonation of hTTR at this cysteine residue can destabilize the hTTR tetramer, an important step in the formation of TTR-related amyloid fibrils. CONCLUSIONS: Administration of a commercial HSA solution that already contains S-sulfonated hTTR could potentially contribute to the development of amyloid-related/polyneuropathy in the critically ill.

Teaching for Practice: The Impact of a Large-Scale Interprofessional Foundational Program.

PURPOSE: The University of Kansas Medical Center has developed an interprofessional education (IPE) foundational program using TeamSTEPPS, a curriculum designed to improve patient care through effective communication and teamwork. The purpose of this study was to understand the impact of the Level 1 program on learners as they develop the attitudes, knowledge, and skills related to interprofessional collaborative practice. METHODS: Learners (n=715) representing 15 professions participated in the Level 1 program. A mixed-methods approach was used to assess achievement of learning objectives, learner reactions, modifications of perceptions and attitudes, acquisition of knowledge and skills, and anticipated behaviors. RESULTS: Learners (n=585, 81.8%) agreed that the program was valuable. Positive changes in attitudes were significant pre-post (p<0.001). An average of 80.3% of learners who responded (n=196, 27.4%) correctly answered knowledge survey questions. Furthermore, analysis of open-ended questions suggested that learners gained an increased appreciation for interprofessional communication and better understanding of the roles of other healthcare professions. CONCLUSIONS: Based on positive learner reactions, changes in attitudes and knowledge, and anticipated behaviors associated with this program, similar approaches that incorporate TeamSTEPPS early in professional curricula may be useful for foundational IPE programming due to the intentional alignment with collaborative practice and orientation towards the Quadruple Aim.

Hospitalized patients' and family members' preferences for real-time, transparent access to their hospital records.

OBJECTIVES: To better understand patient satisfaction and perceived engagement with traditional hospital-based communication and to elicit patient preferences for health information technologies that would lead to improved satisfaction and engagement. STUDY DESIGN: We performed a mixed-methods study involving qualitative interviews followed by a survey of hospitalized patients and their family members at a single large academic medical center. METHODS: We conducted semi-structured interviews with 41 patients and surveyed 267 patients or family members to elicit their perspectives on satisfaction with traditional hospital communication methods, information needed to more fully engage in the patients' medical care, and potential solutions for improved hospital-based communication. RESULTS: Qualitative interviews revealed patients' and family members' dissatisfaction with current hospital-based communication methods. They would prefer more information, in more flexible forms, with real-time digital access and the ability to share within their social and healthcare networks. Quantitative results from the survey supported these premises, with at least the majority of the 267 patients surveyed agreeing across each survey question. Furthermore, participants identified a "communications point person" as the individual who organizes, understands, and communicates about the patient's care, who was often a family member not available at the bedside during daily rounds. Potential solutions included improved transparency about hospital processes, creating systems that allow patients and family to help coordinate and double-check their own health-related communications, and delivering hospital-based communications through digital media. CONCLUSIONS: These study findings provide empiric evidence to hospital decision-makers regarding patient and family preferences for 21st-century hospital-based communication systems.

Pediatric Patients Discharged from the Emergency Department with Abnormal Vital Signs.

INTRODUCTION: Children often present to the emergency department (ED) with minor conditions such as fever and have persistently abnormal vital signs. We hypothesized that a significant portion of children discharged from the ED would have abnormal vital signs and that those discharged with abnormal vital signs would experience very few adverse events. METHODS: We performed a retrospective chart review encompassing a 44-month period of all pediatric patients (aged two months to 17 years) who were discharged from the ED with an abnormal pulse rate, respiratory rate, temperature, or oxygen saturation. We used a local quality assurance database to identify pre-defined adverse events after discharge in this population. Our primary aim was to determine the proportion of children discharged with abnormal vital signs and the frequency and nature of adverse events. Additionally, we performed a sub-analysis comparing the rate of adverse events in children discharged with normal vs. abnormal vital signs, as well as a standardized review of the nature of each adverse event. RESULTS: Of 33,185 children discharged during the study period, 5,540 (17%) of these patients had at least one abnormal vital sign. There were 24/5,540 (0.43%) adverse events in the children with at least one abnormal vital sign vs. 47/27,645 (0.17%) adverse events in the children with normal vital signs [relative risk = 2.5 (95% confidence interval, 1.6 to 2.4)].However, upon review of each adverse event we found only one case that was related to the index visit, was potentially preventable by a 23-hour hospital observation, and caused permanent disability. CONCLUSION: In our study population, 17% of the children were discharged with at least one abnormal vital sign, and there were very few adverse (0.43%) events associated with this practice. Heart rate was the most common abnormal vital sign leading to an adverse event. Severe adverse events that were potentially related to the abnormal vital sign(s) were exceedingly rare. Additional research is needed in broader populations to better determine the rate of adverse events and possible methods of avoiding them.

Interprofessional Education and Practice Guide No. 7: Development, implementation, and evaluation of a large-scale required interprofessional education foundational programme.

Health profession educators and administrators are interested in how to develop an effective and sustainable interprofessional education (IPE) programme. We describe the approach used at the University of Kansas Medical Centre, Kansas City, United States. This approach is a foundational programme with multiple large-scale, half-day events each year. The programme is threaded with common curricular components that build in complexity over time and assures that each learner is exposed to IPE. In this guide, lessons learned and general principles related to the development of IPE programming are discussed. Important areas that educators should consider include curriculum development, engaging leadership, overcoming scheduling barriers, providing faculty development, piloting the programming, planning for logistical coordination, intentionally pairing IP facilitators, anticipating IP conflict, setting clear expectations for learners, publicising the programme, debriefing with faculty, planning for programme evaluation, and developing a scholarship and dissemination plan.
