Improving prehospital stroke diagnosis using natural language processing of paramedic reports.
Accurate prehospital diagnosis of stroke by emergency medical services (EMS) can increase treatments rates, mitigate disability, and reduce stroke deaths. IN this study, the investigators aimed to develop a model that utilized natural language processing of EMS reports and machine learning to improve prehospital stroke identification. The investigators conducted a retrospective study of patients transported by the Chicago EMS to 17 regional primary and comprehensive stroke centers.

Qualitative study to understand ordering of CT angiography to diagnose pulmonary embolism in the emergency room setting.
The purpose of the study was to better understand, using semi-structured interviews, the decision making behind the ordering of CT pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism (PE) in the emergency department. The authors found that EM providers were the main drivers of CTPA ordering, and there was a marginalized role for the radiologist. Experience- and gestalt-based heuristics were the main influencers of CTPA ordering.

Cincinnati prehospital stroke scale can identify large vessel occlusion stroke.
This study explores the hypothesize that a cut-off score of the Cincinnati Prehospital Stroke Scale (CPSS), an assessment tool currently used by emergency medical services (EMS) providers, can be used to identify large vessel occlusion (LVO). Patients with acute ischemic stroke arriving via EMS at a high-volume stroke center in a large city were identified in a prospective, single-center registry. LVO was confirmed via head and neck vessel imaging and CPSS scores were abstracted from pre-hospital EMS records. The researchers conclude that a CPSS score of 3 identifies LVO in AIS patients reliably, and that EMS providers may be able to use the CPSS with a cut-off score to screen for patients with suspected LVO.

Simulation and the diagnostic process: a pilot study of trauma and rapid response teams.
Simulation can be used to recreate conditions that engage teams in the diagnostic process. In contrast to most instruction about diagnostic error, teams learn through realistic experiences and receive timely feedback about their decision-making skills. The purpose of this study was to assess how trauma teams (TrT) and pediatric rapid response teams (RRT) managed scenarios that included a diagnostic error.

Nonlinear imputation of PaO2/FIO2 from SpO2/FIO2 among mechanically ventilated patients in the ICU: a prospective, observational study.
The objective of the study was to validate the superiority of nonlinear imputation of PaO2/FIO2 (a clinical indicator of hypoxaemia) among mechanically ventilated patients and understand what factors influence the accuracy of imputation. It concluded that in mechanically ventilated patients, nonlinear imputation of PaO2/FIO2 from SpO2/FIO2 seems accurate, especially for moderate-severe hypoxemia. Linear and log-linear imputations cannot be recommended.

Paramedic perspectives on barriers to prehospital acute stroke recognition.
The researchers aimed to understand systematically the challenges and barriers faced by paramedics in recognizing stroke presentations in the field. They concluded that while challenges to stroke recognition in the field were slightly different for rural and urban emergency medical service providers, participants concurred that timely, systematic feedback on individual patients and case-based training would strengthen early stroke recognition skills.

Opportunities for earlier HIV diagnosis in a pediatric ED.
The researchers sought to determine whether there were opportunities for earlier HIV diagnosis in the PED for a cohort of young adults diagnosed with HIV. They concluded that there are opportunities for earlier diagnosis of HIV in PEDs, affirming the importance of HIV screening implementation in these settings. However, PEDs are unlikely to have the same frequency of contact with undiagnosed individuals as do adult EDs.

Missed diagnoses of acute myocardial infarction in the emergency department: variation by patient and facility characteristics.
The purpose of this study is to estimate the frequency of missed heart attacks or their precursors (e.g., unstable angina) in the emergency department (ED) by examining use of EDs in the week prior to hospitalization for heart attack. This study of 111,973 patients found an overall rate of 0.9 percent for missed diagnoses of heart attacks.

Motor vehicle crash severity estimations by physicians and prehospital personnel.
The purpose of this study was to determine whether emergency physicians (EPs) and EMS personnel differ in their assessment of motor vehicle collision severity and the potential for serious injury when viewing crash scene photographs. They found excellent crash and injury agreement at both ends of the severity spectrum but only modest agreement, and therefore greater variability, in the middle of the severity spectrum.
