Live tweeting in medicine: 'Tweeting the meeting'.

Medical conferences create an opportunity for lifelong learning for healthcare practitioners. The use of Twitter at such conferences continues to expand. This article focuses on how Twitter can be used by physicians and other healthcare providers at regional, national and international conferences, and also at local conferences, such as grand rounds. It also addresses the potential utility of Twitter chats and journal clubs in the promotion of lifelong learning. The impact of Twitter use in healthcare in general, and specifically at conferences, and how it can be measured, is discussed.

A Novel Maneuver to Treat Refractory Atelectasis in Mechanically Ventilated Children.

We developed a novel airway clearance and lung recruitment maneuver for children with refractory unilateral atelectasis undergoing invasive mechanical ventilation. In this retrospective, single-center, proof of concept study, we describe the steps involved in this novel maneuver and evaluate its effectiveness in 15 patients through objective quantitation of changes in respiratory system compliance and in the degree of atelectasis assessed by a validated Modified Radiology Atelectasis Score. Compared with the premaneuver baseline, the median atelectasis score improved significantly following the maneuver (9 [7.5-10] vs. 1 [0-3.3], respectively, p < 0.01). Likewise, dynamic compliance was significantly higher following the maneuver (0.3 [0.32-0.44] vs. 0.61 [0.53-0.69] mL/kg/cm H 2 O, respectively, p < 0.01). No patients required a bronchoscopy. This simple and effective maneuver resulted in a significant improvement in the degree of atelectasis and dynamic compliance in this cohort of mechanically ventilated children with refractory unilateral atelectasis.

The Temporal Relationship Between Local School Closure and Increased Incidence of Pediatric Diabetic Ketoacidosis.

Importance: The incidence of pediatric diabetic ketoacidosis (DKA) increased early in the COVID-19 pandemic, but the relative contribution of behavioral changes and viral-related pathophysiology are unknown. Objective: To evaluate the relationship between school closure date and onset of increased DKA to help clarify the etiology of the increased incidence. Design: A multi-center, quality-controlled Pediatric Intensive Care Unit (PICU) database was used to identify the number of admissions to a participating PICU with DKA on each calendar day from 60 days before local school closure to 90 days after, and compared to baseline data from the same periods in 2018-2019. Interrupted time series and multiple linear regression analyses were used to identify admission rates that differed significantly between 2020 and baseline. Setting: Eighty-one PICUs in the United StatesParticipants: Children ages 29 days to 17 years admitted to a PICU with DKAExposures: Statewide school closureMain outcome/measure: Rate of admission to the PICU for DKA. Results: There were 1936 admissions for children with DKA in 2020 and 1795 admissions/year to those same PICUs in 2018-2019. Demographics and clinical outcomes did not differ before school closure, but pandemic-era patients were less often white and had longer hospital length of stay in the post-school closure period. The difference between 2020 admissions and 2018-2019 admissions was not different than zero before school closure, and significantly higher than zero after school closure, but was significantly increased in 2020 at >30 days after school closure (p = 0.039). Conclusions/Relevance: An increase in pediatric DKA admissions began one month after school closures. Given that behavioral changes started near school closure dates and viral activity peaked weeks after, this suggests that behavioral factors may not be the primary etiology and it is possible that SARS-CoV-2 infection may have direct effects on pediatric DKA.

Changes in Pediatric ICU Utilization and Clinical Trends During the Coronavirus Pandemic.

BACKGROUND: Children have been less affected by the COVID-19 pandemic, but its repercussions on pediatric illnesses may have been significant. This study examines the indirect impact of the pandemic on a population of critically ill children in the United States. RESEARCH QUESTION: Were there significantly fewer critically ill children admitted to PICUs during the second quarter of 2020, and were there significant changes in the types of diseases admitted? STUDY DESIGN AND METHODS: This retrospective observational cohort study used the Virtual Pediatric Systems database. Participants were 160,295 children admitted to the PICU at 77 sites in the United States during quarters 1 (Q1) and 2 (Q2) of 2017 to 2019 (pre-COVID-19) and 2020 (COVID-19). RESULTS: The average number of admissions was similar between pre-COVID-19 Q1 and COVID-19 Q1 but decreased by 32% from pre-COVID-19 Q2 to COVID-19 Q2 (20,157 to 13,627 admissions per quarter). The largest decreases were in respiratory conditions, including asthma (1,327 subjects in pre-COVID-19 Q2 (6.6% of patients) vs 241 subjects in COVID-19 Q2 (1.8%; P < .001) and bronchiolitis (1,299 [6.5%] vs 121 [0.9%]; P < .001). The percentage of trauma admissions increased, although the raw number of trauma admissions decreased. Admissions for diabetes mellitus and poisoning/ingestion also increased. In the multivariable model, illness severity-adjusted odds of ICU mortality for PICU patients during COVID-19 Q2 increased compared with pre-COVID-19 Q2 (OR, 1.165; 95% CI, 1.00-1.357; P = .049). INTERPRETATION: Pediatric critical illness admissions decreased substantially during the second quarter of 2020, with significant changes in the types of diseases seen in PICUs in the United States. There was an increase in mortality in children admitted to the PICU during this period.

Adherence to pediatric diabetic ketoacidosis guidelines by community emergency departments' providers.

BACKGROUND: Diabetic ketoacidosis (DKA) is a common presentation of type I diabetes mellitus to the emergency departments. Most children with DKA are initially managed in community emergency departments where providers may not have easy access to educational resources or pediatric-specific guidelines and protocols that are readily available at pediatric academic medical centers. The aim of this study is to evaluate adherence of community emergency departments in the state of Indiana to the pediatric DKA guidelines. METHODS: We performed a retrospective chart review of patients, age 18 years of age or under, admitted to the pediatric intensive care unit with a diagnosis of DKA. RESULTS: A total of 100 patients were included in the analysis. Thirty-seven percent of patients with DKA were managed according to all six guideline parameters. Only 39% of patients received the recommended hourly blood glucose checks. Thirty percent of patients received intravenous insulin bolus, which is not recommended. CONCLUSIONS: Non-adherence to pediatric DKA guidelines still exists in the state of Indiana. Further, larger studies are needed to reveal the etiology of non-adherence to pediatric DKA guidelines and strategies to improve that adherence.
