Practice Patterns for Acute Asthma Exacerbation in Adult Patients Admitted to US Intensive Care Units.

RATIONALE: Guidelines recommend systemic corticosteroids and inhaled beta-agonists for patients with severe asthma exacerbation admitted to intensive care units (ICUs). The benefits and utilization of adjunct treatments after guideline recommended first-line treatments have been initiated are unclear. METHODS: Using the Premier Inc. PINC AI multicenter database (2016-2022), we sought to explore the use of adjunct interventions (medications [e.g., magnesium, leukotriene inhibitors, terbutaline, heliox]; and procedures [e.g., invasive and non-invasive mechanical ventilation]) for adult patients admitted to United States (US) ICUs with acute asthma exacerbations. We used hierarchical generalized linear models to calculate risk-adjusted rates of adjunct interventions and quantified between-hospital variation in adjunct interventions using the intraclass correlation coefficient (ICC - higher values correspond to higher between hospital variation). We then used K-means clustering to identify groups of hospitals with similar risk-adjusted practice profiles of all adjunct treatments and examined associations between identified hospital clusters and patient outcomes. RESULTS: We identified 62,392 patients from 961 hospitals for inclusion. Adjunct interventions with the highest between hospital variation after risk-adjustment were heliox (ICC 91%), inhaled steroids (ICC 23%), invasive mechanical ventilation (ICC 21%), terbutaline (ICC 22%), paralytics (ICC 16%), and non-invasive ventilation (ICC 15%). K-means clustering identified two distinct hospital clusters: patients admitted to cluster 1 hospitals (399 hospitals) had higher risk-adjusted rates of non-invasive ventilation (51% vs 33%) compared to patients admitted to cluster 2 hospitals (234 hospitals) which had higher risk-adjusted rates of invasive mechanical ventilation (63% vs 30%). Cluster 2 was associated with fewer hospital free days (beta -0.75 days, CI -0.95, -0.55 days) and increased in-hospital mortality (aOR 1.28, CI 1.17, 1.40). CONCLUSIONS: The use of adjunct interventions for patients with severe asthma exacerbations vary widely across US hospitals; however, hospitals generally fall into two clusters differentiated primarily by the use of invasive or non-invasive mechanical ventilation. Our results help to inform usual care arms of future comparative effectiveness studies and efforts to standardize asthma practice.

Impact of sleep deficiency on surgical performance: a prospective assessment.

STUDY OBJECTIVES: Sleep deficiency can adversely affect the performance of resident physicians, resulting in greater medical errors. However, the impact of sleep deficiency on surgical outcomes, particularly among attending surgeons, is less clear. METHODS: Sixty attending surgeons from academic and community departments of surgery or obstetrics and gynecology were studied prospectively using direct observation and self-report to explore the effect of sleep deprivation on patient safety, operating room communication, medical errors, and adverse events while operating under 2 conditions, post-call (defined as > 2 hours of nighttime clinical duties) and non-post-call. RESULTS: Each surgeon contributed up to 5 surgical procedures post-call and non-post-call, yielding 362 cases total (150 post-call and 210 non-post-call). Most common were caesarian section and herniorrhaphy. Hours of sleep on the night before the operative procedure were significantly less post-call (4.98 ± 1.41) vs non-post-call (6.68 ± 0.88, P < .01). Errors were infrequent and not related to hours of sleep or post-call status. However, Non-Technical Skills for Surgeons ratings demonstrated poorer performance while post-call for situational awareness, decision-making, and communication/teamwork. Fewer hours of sleep also were related to lower ratings for situational awareness and decision-making. Decreased self-reported alertness was observed to be associated with increased procedure time. CONCLUSIONS: Sleep deficiency in attending surgeons was not associated with greater errors during procedures performed during the next day. However, procedure time was increased, suggesting that surgeons were able to compensate for sleep loss by working more slowly. Ratings on nontechnical surgical skills were adversely affected by sleep deficiency. CITATION: Quan SF, Landrigan CP, Barger LK, et al.

Inpatient albuterol spacing as an indicator of discharge readiness.

INTRODUCTION: In children admitted for asthma exacerbation, multiple evidence-based, clinical practice guidelines exist to identify readiness for discharge. At many institutions, weaning of albuterol is part of the discharge process, though presently there is limited evidence to guide best practice. We sought to determine how many children required escalation of care once placed on every 4-h dosing of albuterol. METHODS: We performed a consecutive case series of pediatric patients between 5 and 18 years of age admitted to a single tertiary care center's pediatric hospitalist service between April 2015 and April 2018 with a discharge diagnosis of asthma. Patients admitted to the intensive care unit (PICU) or a subspecialty service were excluded, as has been done previously. Time between albuterol administrations was tracked. "Treatment escalation" was defined as when a patient required more frequent albuterol more dosing after previously tolerating albuterol doses separated by more than 3.5 h. RESULTS: A total of 331 patients met inclusion criteria; 136 were female (41.1%), and the average age was 8.8 years. Twenty-six of the 331 patients (7.8%) required escalation of albuterol therapy. Eleven patients returned to the emergency department (ED) following discharge, 2 of which had experienced treatment escalation while admitted. CONCLUSIONS: Our case series showed that most patients were safe to discharge after spacing albuterol treatments to 4 h, with few returns to the ED and readmissions. Albuterol spacing to every 4 h once appears to be a reasonable discharge criterion, but future studies are needed to determine if this is a safe and efficient.

Risk factors for early PICC removal: A retrospective study of adult inpatients at an academic medical center.

BACKGROUND: Use of PICCs has been rising since 2001. They are used when long-term intravenous access is needed and for blood draws in patients with difficult venous access. OBJECTIVE: To determine which risk factors contribute to inappropriate PICC line insertion defined as removal of a PICC within five days of insertion for reasons other than a PICC complication. DESIGN: Retrospective, observational study. SETTING: Tertiary-care, Level 1 trauma center. PATIENTS: Adult patients with a PICC removed 1/1/2017 to 5/4/2020. MEASUREMENTS: Frequency of PICC removal within five days of insertion and associated risk factors for early removal. RESULTS: Between 1/1/2017 and 5/4/2020, 995 of 5348 PICCs inserted by the IV nursing team were removed within five days (19%). In 2017, 5 of 429 PICCs developed a central line-associated infection (1.2%) and 29 of 429 PICCs developed symptomatic venous thromboembolism (6.7%). Patients with PICCs whose primary service was in an ICU were independently at higher risk of early removal (OR 1.44, 95% CI 1.14, 1.83); weekday insertion was independently associated with a lower likelihood of early removal compared to weekend insertion (OR 0.60; 95% CI 0.49, 0.75). LIMITATION: PICC removal after discharge was not assessed and paper records were likely incomplete and biased. CONCLUSION: Nearly one in five PICCs were removed within five days. Patients whose primary team was in an ICU and PICCs ordered on weekends were at independently higher risk of early removal.

Combined Medicine-Pediatrics Fellowships: A Guide for Fellowship Directors and Residents.

Dual training in Internal Medicine-Pediatrics (MedPeds) was recognized by the American Board of Medical Specialties in 1967. Residents complete 24 months each in Internal Medicine and Pediatrics and are board-eligible for both at the conclusion of training. Graduates are eligible for fellowships in either or both fields. Many graduates pursue fellowship training. A small absolute number of graduates apply for dual training in adult and pediatric subspecialties, but those that do bring direct, in-depth clinical experience across the lifespan, and familiarity with care in both pediatric and adult settings. As such, they contribute unique perspectives and capabilities to their fellowship and future practice. This includes the ability to provide subspecialty care in settings with limited resources, where they are able to address needs without age restrictions, and in the transition of subspecialty care for emerging adults with childhood-onset conditions. Due to the small number of applicants pursuing joint adult and pediatric fellowships, many fellowship directors may have limited experience with dual fellowships but may want to create opportunities for these unique trainees. This summary was developed jointly by residents, fellows, MedPeds program directors, and fellowship directors in Pediatrics and Internal Medicine subspecialties, and approved by their respective leadership councils to offer some key points on common questions, suggest additional resources, and share best practices, with a goal of facilitating this process for fellowship programs and residents alike.

Double Crossed: A Case of La Crosse Encephalitis.

CASE REPORT: A 10-year-old male with T1DM and recent travel to North Carolina presented to an ED with 1 day of fever, vomiting, and headaches. He was discharged home with the presumptive diagnosis of viral gastroenteritis but returned nine hours later, agitated, and unable to speak. CSF showed pleocytosis. MRI brain was normal, and EEG showed intermittent seizures. He was started on antiepileptics. Antibiotics were discontinued after negative bacterial work-up. Repeat MRI brain one week later showed enhancement in the left cerebral cortex. IVIG was started due to concern for autoimmune encephalitis. Repeat lumbar puncture was positive for La Crosse virus IgM. DISCUSSION: This is the first case of La Crosse encephalitis (LACe) reported in Rhode Island.1 La Crosse virus (LACv) is a ssRNA Bunyavirus transmitted by the eastern tree-hole mosquito typically between July and September. LACv is endemic to the upper Midwestern US and Appalachia. In 2018, 81 of 86 total cases reported by the CDC were pediatric. Children are more likely to present with vomiting, seizures, and focal cortical inflammation or cerebral edema on brain imaging. IgM may be negative early in the disease course. Treatment is antiepileptics and supportive care.

Bioinformatic approach to the genetics of preeclampsia.

OBJECTIVE: To identify candidate genes and genetic variants for preeclampsia using a bioinformatic approach to extract and organize genes and variants from the published literature. METHODS: Semantic data-mining and natural language processing were used to identify articles from the published literature meeting criteria for potential association with preeclampsia. Articles were manually reviewed by trained curators. Cluster analysis was used to aggregate the extracted genes into gene sets associated with preeclampsia or severe preeclampsia, early or late preeclampsia, maternal or fetal tissue sources, and concurrent conditions (ie, fetal growth restriction, gestational hypertension, or hemolysis, elevated liver enzymes, and low platelet count [HELLP]). Gene ontology was used to organize this large group of genes into ontology groups. RESULTS: From more than 22 million records in PubMed, with 28,000 articles on preeclampsia, our data-mining tool identified 2,300 articles with potential genetic associations with preeclampsia-related phenotypes. After curation, 729 articles were "accepted" that contained "statistically significant" associations with 535 genes. We saw distinct segregation of these genes by severity and timing of preeclampsia, by maternal or fetal source, and with associated conditions (eg, gestational hypertension, fetal growth restriction, or HELLP syndrome). CONCLUSION: The gene sets and ontology groups identified through our systematic literature curation indicate that preeclampsia represents several distinct phenotypes with distinct and overlapping maternal and fetal genetic contributions. LEVEL OF EVIDENCE: III.
