In order to leverage novel sequencing techniques for cloning genes in eukaryotic organisms with complex genomes, the false positive rate of variant discovery must be controlled for by experimental design and informatics. We sequenced five lines from three pedigrees of EMS mutagenized Sorghum bicolor, including a pedigree segregating a recessive dwarf mutant. Comparing the sequences of the lines, we were able to identify and eliminate error prone positions. One genomic region contained EMS mutant alleles in dwarfs that were homozygous reference sequence in wild-type siblings and heterozygous in segregating families...

Providing safe and error-free patient care should resonate well with all healthcare providers including emergency medical technicians. The environments and circumstances in which emergency medical services (EMS) provide patient care inevitably create risks to both the provider and patient. This article explores the concepts of patient safety, errors, near misses, adverse events, and Just Culture. Literature raises concerns about the lack of data collection on both patient and provider safety and research on these safety topics in EMS...

BACKGROUND: Prehospital pediatric drug dosing errors affect 56,000 U.S. children annually. An accurate weight is the first step in accurate dosing. To date, the accuracy of Emergency Medical Dispatcher (EMD) obtained weights has not been evaluated. We hypothesized that EMD could obtain accurate pediatric weights. METHODS: We used a convenience sample of patients 12 years and younger that were transported by EMS to one children's hospital. EMD obtained patient weight (DW) from the 9-1-1 caller...

INTRODUCTION: Current Emergency Medical Services (EMS) documentation practices usually occur from memory after an event is over. While this practice is fairly standard, it is unclear if it can introduce significant error. Modern technology has seen the increased use of recorded video by society to more objectively document notable events. Stationary mounted cameras, cell-phone cameras, and law enforcement officer Body-Worn Cameras (BWCs) are increasingly used by society for this purpose...

We investigated feasibility and safety of the RhinoChill (RC) transnasal cooling system initiated before achieving a protected airway during cardiopulmonary resuscitation (CPR) in a prehospital setting.In out-of-hospital cardiac arrest (OHCA), transnasal evaporative cooling was initiated during CPR, before a protected airway was established and continued until either the patient was declared dead, standard institutional systemic cooling methods were implemented or cooling supply was empty. Patients were monitored throughout the hypothermia period until either death or hospital discharge...

BACKGROUND: Motif search is an important step in extracting meaningful patterns from biological data. The general problem of motif search is intractable and there is a pressing need to develop efficient, exact and approximation algorithms to solve this problem. In this paper, we present several novel, exact, sequential and parallel algorithms for solving the (l,d) Edit-distance-based Motif Search (EMS) problem: given two integers l,d and n biological strings, find all strings of length l that appear in each input string with atmost d errors of types substitution, insertion and deletion...

OBJECTIVES: Patient handoff occurs when responsibility for patient diagnosis, treatment, or ongoing care is transferred from one healthcare professional to another. Patient handoff is an integral component of quality patient care and is increasingly identified as a potential source of medical error. However, evaluation of handoff from field providers to ED personnel is limited. We here present a quantitative analysis of the information transferred from EMS providers to ED physicians during handoff of critically ill and injured patients...

INTRODUCTION: Telemedical concepts in emergency medical services (EMS) lead to improved process times and patient outcomes, but their technical performance has thus far been insufficient; nevertheless, the concept was transferred into EMS routine care in Aachen, Germany. This study evaluated the system's technical performance and compared it to a precursor system. METHODS: The telemedicine system was implemented on seven ambulances and a teleconsultation centre staffed with experienced EMS physicians was established in April 2014...

Mixed methods research has significant potential to broaden the scope of emergency care and specifically emergency medical services investigation. Mixed methods studies involve the coordinated use of qualitative and quantitative research approaches to gain a fuller understanding of practice. By combining what is learnt from multiple methods, these approaches can help to characterise complex healthcare systems, identify the mechanisms of complex problems such as medical errors and understand aspects of human interaction such as communication, behaviour and team performance...

BACKGROUND: In many industries, limiting variability in process has been associated with a reduction in errors. Hypoglycemia is a common prehospital diabetic emergency for which most EMS systems have a treatment protocol. OBJECTIVE: To examine the treatment variability for prehospital hypoglycemia within EMS protocols in the U.S. METHODS: EMS protocols were reviewed in a structured fashion from 2 sources: the website and through manual identification from the 50 largest populated cities in the U...

INTRODUCTION: During mass-casualty incidents (MCIs), patient volume often overwhelms available Emergency Medical Services (EMS) personnel. First responders are expected to triage, treat, and transport patients in a timely fashion. If other responders could triage accurately, prehospital EMS resources could be focused more directly on patients that require immediate medical attention and transport. HYPOTHESIS: Triage accuracy, error patterns, and time to triage completion are similar between second-year primary care paramedic (PCP) and fire science (FS) students participating in a simulated MCI using the Sort, Assess, Life-saving interventions, Treatment/Transport (SALT) triage algorithm...

INTRODUCTION: The objective is to evaluate the accuracy of medication dosing and the time to medication administration in the prehospital setting using a novel length-based pediatric emergency resuscitation tape. METHODS: This study was a two-period, two-treatment crossover trial using simulated pediatric patients in the prehospital setting. Each participant was presented with two emergent scenarios; participants were randomized to which case they encountered first, and to which case used the National Park Service (NPS) emergency medical services (EMS) length-based pediatric emergency resuscitation tape...

BACKGROUND: The self-consciousness and practicality of preferentially prescribed essential medicines (EMs) are not high enough in county hospitals. The purposes of this study were to use the information-motivation-behavioral skills (IMB) model to identify the predictors of essential medicines prescribing behavior (EMPB) among doctors and to examine the association between demographic variables, IMB, and EMPB. METHODS: A cross-sectional study was carried out to assess predictive relationships among demographic variables and IMB model variables using an anonymous questionnaire administered in nine county hospitals of Anhui province...

BACKGROUND: Mass-casualty incidents (MCIs) present a unique challenge with regards to triage as patient volume often outweighs the number of available Emergency Medical Services (EMS) providers. A possible strategy to optimize existing triage systems includes the use of other first responder groups, namely fire and police, to decrease the triage time during MCIs, allowing for more rapid initiation of life-saving treatment and prioritization of patient transport. Hypothesis First-year primary care paramedic (PCP), fire, and police trainees can apply with similar accuracy an internationally recognized MCI triage tool, Sort, Assess, Life-saving interventions, Treatment/transport (SALT), immediately following a brief training session, and again three months later...

Prehospital dosing errors affect approximately 56,000 US children yearly. To decrease these errors, barriers, enablers and solutions from the paramedic (EMT-P) and medical director (MD) standpoint need to be understood. We conducted a mixed-methods study of EMT-P and MDs in Michigan utilizing focus groups (FG). FGs were held at EMS agencies and state EMS conferences. Questions focused on the drug dose delivery process, barriers and enablers to correct dosing and possible solutions to decrease errors. Responses were coded by the research team for themes and number of response mentions...

Two of the most prominent frameworks to develop in ecology over the past decade are metacommunity ecology, which seeks to characterize multispecies distributions across space, and occupancy modeling, which corrects for imperfect detection in an effort to better understand species occurrence patterns. Although their goals are complementary, metacommunity theory and statistical occupancy modeling methods have developed independently. For instance, the elements of metacommunity structure (EMS) framework uses species occurrence data to classify metacommunity structure and link it to underlying environmental gradients...

UNLABELLED: Prehospital treatment protocols call for intravenous (IV) fluid for patients with shock, yet the measurement accuracy of administered fluid volume is unknown. The purpose of the current study was to assess the accuracy of documented and self-reported fluid volumes administered to medical patients by paramedics during prehospital care. We conducted a pilot, observational study nested within a parent cohort study of prehospital biomarkers in a single EMS agency transporting patients to a tertiary care hospital in Pittsburgh, Pennsylvania over 8 months...

In quantitative emission tomography, tumor activity is typically estimated from calculations on a region of interest (ROI) identified in the reconstructed slices. In these calculations, unpredictable bias arising from the null functions of the imaging system affects ROI estimates. The magnitude of this bias depends upon the tumor size and location. In prior work it has been shown that the scanning linear estimator (SLE), which operates on the raw projection data, is an unbiased estimator of activity when the size and location of the tumor are known...
