Near-miss events detected using the emergency department trigger tool.
The purpose of this study was to explore near misses and their significance for quality and safety in the emergency department (ED). This study presents a secondary analysis of data from a retrospective investigation of the ED Trigger Tool (EDTT) at an urban, academic ED. The EDTT, a computerized query for triggers, was applied to 13 months of ED visit data, and 5582 selected records were reviewed using a two-tiered approach. Events were categorized by occurrence (ED vs. present on arrival [POA]), severity, omission/commission, and type, employing a taxonomy featuring categories, subcategories, and cross-cutting modifiers. The researchers identified 1458 ED near misses in 1269 of the 5582 records and 80 near misses that were POA. Patient care events constituted the majority of ED near misses, including diagnostic delays, treatment delays, and monitoring failures, primarily influenced by ED boarding and overcrowding. Medication events ranked second in frequency (17%), with 80 medication administration errors identified. Among the 80 POA events, 42% were linked to overanticoagulation. It was estimated that 19.3% of all ED visits involved a near miss.

Perspectives of emergency clinicians about medical errors resulting in patient harm or malpractice litigation.
This cross-sectional study examined survey responses about medical error outcomes completed by emergency department attending physicians and advanced practice clinicians regarding what might be considered excessive testing. The authors surveyed 1222 clinicians and the mean score was greater for fear of harm to patients than fear of a malpractice suit. This finding was true regardless of clinician subtype, experience, or sex.

Multicenter test of an emergency department trigger tool for detecting adverse events.
This study details a novel emergency department (ED) trigger tool to detect adverse events using a multidisciplinary, multicenter approach developed by the authors. They conducted a multicenter test of the tool and assessed its performance. The study was conducted during a 13-month period at 4 EDs. Patients age 18 years and older with Emergency Severity Index acuity levels of 1 to 3 by a provider were eligible. Fifty randomly selected visits at each site were reviewed a month. Events were classified by level of harm using the Medication Event Reporting and Prevention (MERP) Index, ranging from a near miss (A) to patient death (I). They captured 2594 visits that are representative, within site, of their patient population. Overall, the sample is 64% white, 54% female, and with a mean age of 51. Variability was observed between sites for age, race, and insurance, but not sex. A total of 240 events were identified in 228 visits (8.8%) of which 53.3% were present on arrival, 19.7% were acts of omission, and 44.6% were medication related. A MERP F score (contributing to need for admission, higher level of care, or prolonged hospitalization) was the most common severity level at 35.4%. Overall, 185 (77.1%) of 240 events involved patient harm (MERP level ≥ E), affecting 175 visits (6.7%). Triggers were present in 951 visits (36.6%). Presence of any trigger was strongly associated with an AE. Ten triggers were individually associated with AEs. Variability was observed across sites in individual trigger associations, event rates, and categories, but not in severity ratings of events. The overall false-negative rate was 6.1%.

Practical considerations in use of trigger tool methodology in the emergency department.
This article’s purpose was to provide general observations, guidance, and lessons learned in the use of a trigger tool in the emergency department (ED) for adverse events (AEs). The authors identified 46 triggers in the initial ED trigger tool. They tried to include triggers of various types to capture events related to different aspects of an ED visit. The trigger events were reviewed by first-level reviewers, who are typically nurses, and then by second-level reviewers, who are usually other clinicians. An AE was identified using the AHRQ definition adopted by the IHI GTT, which is limited to physical (but not emotional or mental) harm. It must be unintentional and attributable to healthcare. Acts of omission must be included not just acts of commission. They used a modified National Coordinating Council’s Medication Event Reporting and Prevention (MERP) Index to assess severity of harm. MERP E-I events are identified as those that had interventions, with MERP A-D events noted. They outlined several salient areas for consideration in implementing a trigger tool in the ED setting and also specified how to address the highlighted issues.

Identifying trigger concepts to screen emergency department visits for diagnostic errors.
The diagnostic process is a vital component of safe and effective emergency department (ED) care. There are no standardized methods for identifying or reliably monitoring diagnostic errors in the ED, impeding efforts to enhance diagnostic safety. In this study, the investigators sought to identify trigger concepts to screen ED records for diagnostic errors and describe how they can be used as a measurement strategy to identify and reduce preventable diagnostic harm.

Adverse events and emergency department opioid prescriptions in adolescents.
Understanding the risks associated with opioid prescription in adolescents is critical for informing opioid policy, but the risks are challenging to quantify given the lack of randomized trial data. Using a regression discontinuity design, the investigators exploited a discontinuous increase in opioid prescribing in the emergency department (ED) when adolescents transitioned from "child" to "adult" at age eighteen to estimate the effect of an ED opioid prescription on subsequent opioid-related adverse events.

The emergency department trigger tool: validation and testing to optimize yield.
Researchers validated the emergency department trigger tool (EDTT) in an independent sample and compared record selection approaches to optimize yield for quality improvement. In this single-site study of the EDTT, they observed high levels of validity in trigger selection, yield, and representativeness of adverse events, with yields that are superior to estimates for traditional approaches to adverse event detection. Record selection using weighted triggers outperformed a trigger count threshold approach and far outperformed random sampling from records with at least one trigger. They concluded that the EDTT is a promising efficient and high-yield approach for detecting all-cause harm to guide quality improvement efforts in the emergency department.

Disseminated intravascular coagulation is an independent predictor of adverse outcomes in children in the emergency department with suspected sepsis.
The purpose of this study was to evaluate the impact of early disseminated intravascular coagulation (DIC) on illness severity in children using a database of emergency department ED encounters for children with suspected sepsis, in view of similar associations in adults. The investigators concluded that a DIC score of ≥3 was an independent predictor for both vasopressor use and mortality in this pediatric cohort, distinct from the adult overt DIC score cutoff of ≥5.

The emergency department trigger tool: a novel approach to screening for quality and safety events.
The goal of this study was to develop an automated version of a previously developed emergency department (ED) trigger tool to track the likelihood of an adverse event. Thirty triggers were associated with risk of harm. The authors identified 1,726 records out of 76,894 ED visits with greater than or equal to 1 trigger. They compared the results of the automated tool to the previous version and found it performed well. They began with a broad set of candidate triggers and validated a computerized query that eliminates the need for manual screening of triggers and also identified a refined set of triggers associated with adverse events in the ED.

Adverse events present on arrival to the emergency department: the ED as a dual safety net.
This study examined the prevalence of adverse events due to medication-related or patient care-related events that present on arrival (POA) to the emergency department (ED). This retrospective observation study tested the ED Trigger Tool from data at an urban academic medical center. Adults who completed an ED visit were eligible (N=92,859). A total of 5,582 visits gave a trigger. The majority of AEs (1,181) identified were from patients who were white and older. In total, POA AEs accounted for an estimated 7.65% of ED visits.

Development and validation of a pragmatic natural language processing approach to identifying falls in older adults in the emergency department.
This study examined development and validation of a pragmatic natural language processing (NLP) approach to identify fall risk in older adults after emergency department (ED) visits. A single center retrospective review using data from 500 emergency department provider notes on older adults age 65 and older were random selected for analysis. The NLP algorithm successfully identified falls in ED notes with over 90% precision, and looks promising to reduce labor-intensive manual abstraction.

Critical review, development, and testing of a taxonomy for adverse events and near misses in the emergency department.
Researchers created and tested a taxonomy for adverse events (AEs) and near misses for use in the emergency department (ED). This taxonomy is patient-centered, as opposed to most taxonomies which fail to describe harm experienced by patients and focus instead on errors and uses too broad categorizations. The authors reviewed candidate taxonomies using an iterative process and selected the Adventist Health Systems AE taxonomy and modified it for use in the ED. After testing with reviewers, agreement with the criterion standard was 92% at the category level and 88% at the subcategory level. Performance from individual raters ranged from very good (88%) to near perfect (98%) at the main category level.

Venous thromboembolism prevention in emergency general surgery: a review.
Operatively and nonoperatively treated emergency general surgery patients are at a comparatively high risk of venous thromboembolism (VTE). This review found that, despite gaps in existing literature with respect to this increasing patient population, successful best practices can be applied. Best practices include assessment of VTE risk, optimal prophylaxis, and physician, nurse, and patient education regarding the use of mechanical and pharmacologic VTE prophylaxis and institutional policies.

Using the Hendrich II Inpatient Fall Risk Screen to predict outpatient falls after emergency department visits.
This study examined the utility of using the Hendrich II Inpatient Fall Risk Screen to predict outpatient falls in elderly patients after emergency department (ED) visits. Individuals aged 65 and older seen in the ED from January 2013 to September 30, 2015 participated in the study. The Hendrich II screen was found to correlate with outpatient falls, but it is likely it would have little utility as a stand-alone fall screen. When the screen was combined with other potential confounders or predictors, the screen performed much better.

Voluntary medical incident reporting tool to improve physician reporting of medical errors in an emergency department.
A web-based, password-protected tool was developed by members of a quality assurance committee for ED providers to report incidents that they believe could impact patient safety. The researchers found that the utilization of this system in one residency program with two academic sites resulted in an increase from 81 reported incidents in 2009, the first year of use, to 561 reported incidents in 2012.
