Cause-and-effect analysis of risk management files to assess patient care in the emergency department

Emergency Department and Urgent Care Medical Malpractice Claims 2001-15

Introduction

This study reviews malpractice, also called medical professional liability (MPL), claims involving adult patients cared for in emergency departments (ED) and urgent care settings.

Methods

We conducted a retrospective review of closed MPL claims of adults over 18 years, from the Medical Professional Liability Association’s Data Sharing Project database from 2001–2015, identifying 6,779 closed claims. Data included the total amount, origin, top medical specialties named, chief medical factors, top medical conditions, severity of injury, resolution, average indemnity, and defense costs of closed claims.

Results

Of 6,779 closed claims, 65.9% were dropped, withdrawn, or dismissed. Another 22.8% of claims settled for an average indemnity of $297,709. Of the 515 (7.6%) cases that went to trial, juries returned verdicts for the defendant in 92.6% of cases (477/515). The remaining 7.4% of cases (38/515) were jury verdicts for the plaintiff, with an average indemnity of $816,909. The most common resulting medical condition cited in paid claims was cardiac or cardiorespiratory arrest (10.4%). Error in diagnosis was the most common chief medical error cited in closed claims. Death was the most common level of severity listed in closed (38.5%) and paid (42.8%) claims. Claims reporting major permanent injury had the highest paid-to-closed ratio, and those reporting grave injury had the highest average indemnity of $686,239.

Conclusion

This retrospective review updates the body of knowledge surrounding medical professional liability and represents the most recent analysis of claims in emergency medicine. As the majority of emergency providers will be named in a MPL claim during their career, it is essential to have a better understanding of the most common factors resulting in MPL claims.

Perceived Roles of Bhutanese Health Care Professionals in Improving Patient Safety: A Qualitative Exploratory Descriptive Study

BACKGROUND AND OBJECTIVES

Patient safety is a vital component of high quality health care and all health care professionals have a responsibility for ensuring the delivery of safe care to patients. However, little is known about how Bhutanese health care professionals perceive their roles in improving patient safety. This study aimed to explore how Bhutanese health care professionals, educators, managers, and policy makers perceived their roles in improving patient safety.

METHODS

Undertaken as a naturalistic inquiry using a qualitative exploratory descriptive research approach, a criterion-based stratified purposive sample of 94 health care professionals and managers from the Ministry of Health, a training institute, and 3 levels of hospitals were interviewed. All interview data were analyzed using content and thematic analysis strategies.

RESULTS

Data analysis identified 4 broad themes. Health care professionals' perceived role in safety and quality included formulating and implementing patient safety rules; management and administration of units and hospitals; patient assessment and management; and setting professional norms (including norms about peer influence and patient care/interaction).

CONCLUSION

The findings revealed that Bhutanese health care professionals were aware of their roles in improving patient safety processes and practices, and providing interprofessional education or training to all levels of health care professionals could help improve communication and patient safety in the Bhutanese health care system.

Many Opportunities to Record, Diagnose, or Treat Injection Drug-related Infections Are Missed: A Population-based Cohort Study of Inpatient and Emergency Department Settings

BACKGROUND

Injection drug use (IDU) and IDU-related infections have increased dramatically. However, the incidence of IDU-related infections may be underreported because drug use is not recorded in diagnostic records where associated infections are identified. Our goal was to estimate a more accurate incidence of IDU-related infections by including IDU-related infections not recorded at the time infections are diagnosed.

METHODS

We performed a retrospective cohort study using inpatient and emergency department visits from the Healthcare Cost and Utilization Project for California, Florida, and New York. We identified all patients diagnosed with bacteremia or sepsis, endocarditis, osteomyelitis or septic arthritis, and skin or soft tissue infection. We estimated the incidence of IDU-related infections by identifying cases where drug use was recorded at the time of an infection and cases where drug use was not recorded at the time of infection but within 6 months before or after the infection diagnosis. We also analyzed factors associated with unrecorded IDU.

RESULTS

There has been an increasing trend in the number of IDU-related infections. The annual number of IDU-related infections increased between 105% and 218% after incorporating infections in which drug use was unrecorded. Factors associated with drug use being unrecorded included emergency department diagnosis, the level of hospital experience treating drug use, age <18 years, and having Medicare as the primary payer.

CONCLUSIONS

More than half of all IDU-related infections may be unrecorded in existing surveillance estimates. There may be many missed opportunities to record, diagnose, or treat underlying drug abuse among patients presenting with IDU-related infections.

Debunking the myth that the majority of medical errors are attributed to communication

CONTEXT

Many articles, book chapters and presentations begin with a declaration that the majority of medical errors are attributed to communication. However, this statement may not be supported by the research reported in the literature.

OBJECTIVES

The purpose of this systematic review is to identify where errors are reported in the research literature.

METHODS

A systematised review was conducted of research articles over the last 20 years (1998-2018) indexed in PubMed/MEDLINE and the Cumulative Index to Nursing and Allied Health (CINAHL) using term combinations: medical errors, research and communication. Inclusion was based on reported generalised primary research of medical error and the reported causes.

RESULTS

This systematised review resulted in 2881 research articles, which produced 42 that met the inclusion criteria. Although there was some overlap, three categories of errors were dominant in this research: errors of commission (20 articles; 47.6%), errors of omission (six articles; 14.2%) and errors through communication (four articles; 9.5%). There were 12 (28.5%) articles in which all three categories together significantly contributed to error. Of these 12 articles, errors of commission or omission were dominant in nine articles (21.4%) and errors of communication were prevalent in only three articles (7%).

CONCLUSIONS

The assertion that the majority of medical errors can be attributed to miscommunication is not supported by this systematic review. Overwhelmingly, most reported errors are attributed to errors of omission or commission. Intentionally or unintentionally providing misinformation may mislead patient safety initiatives, and research and funding agency priorities.

Anaesthesiology students' Non-Technical skills: development and evaluation of a behavioural marker system for students (AS-NTS)

BACKGROUND

Non-Technical Skills (NTS) are becoming more important in medical education. A lack of NTS was identified as a major reason for unsafe patient care, favouring adverse events and team breakdown. Therefore, the training of NTS should already be implemented in undergraduate teaching. The goal of our study was to develop and validate the Anaesthesiology Students' Non-Technical Skills (AS-NTS) as a feasible rating tool to assess students' NTS in emergency and anaesthesiology education.

METHODS

The development of AS-NTS was empirically grounded in expert- and focus groups, field observations and data from NTS in medical fields. Validation, reliability and usability testing was conducted in 98 simulation scenarios, during emergency and anaesthesiology training sessions.

RESULTS

AS-NTS showed an excellent interrater reliability (mean 0.89), achieved excellent content validity indexes (at least 0.8) and was rated as feasible and applicable by educators. Additionally, we could rule out the influence of the raters' anaesthesiology and emergency training and experience in education on the application of the rating tool.

CONCLUSIONS

AS-NTS provides a structured approach to the assessment of NTS in undergraduates, providing accurate feedback. The findings of usability, validity and reliability indicate that AS-NTS can be used by anaesthesiologists in different year of postgraduate training, even with little experience in medical education.

Malpractice in Emergency Medicine-A Review of Risk and Mitigation Practices for the Emergency Medicine Provider

BACKGROUND

Malpractice in emergency medicine is of high concern for medical providers, the fear of which continues to drive decision-making. The body of evidence evaluating risk specific to emergency physicians is disjointed, and thus it remains difficult to derive cohesive themes and strategies for risk minimization.

OBJECTIVE

This review evaluates the state of malpractice in emergency medicine and summarizes a concise approach for the emergency physician to minimize risk.

DISCUSSION

The environment of the emergency department (ED) represents moderate overall malpractice risk and yields a heavy burden in finance and time. Key areas of relatively high litigation occurrence include missed acute myocardial infarction, missed fractures/foreign bodies, abdominal pain/appendicitis, wounds, intracranial bleeding, aortic aneurysm, and pediatric meningitis. Mitigation of risk is best accomplished through constructive communication, intelligent documentation, utilization of clinical practice guidelines and generalizable diagnoses, careful management of discharge against medical advice, and establishing follow-up for diagnostic studies ordered while in the ED (especially x-ray studies). Communication breakdown seems to be more predictive of malpractice litigation than injury experienced.

CONCLUSIONS

There are consistent diagnoses that are associated with increased litigation incidence. A combination of mitigation approaches may assist providers in mitigation of malpractice risk.

Review article: A systematic review of emergency department incident classification frameworks

As in any part of the hospital system, safety incidents can occur in the ED. These incidents arguably have a distinct character, as the ED involves unscheduled flows of urgent patients who require disparate services. To aid understanding of safety issues and support risk management of the ED, a comparison of published ED specific incident classification frameworks was performed. A review of emergency medicine, health management and general medical publications, using Ovid SP to interrogate Medline (1976-2016) was undertaken to identify any type of taxonomy or classification-like framework for ED related incidents. These frameworks were then analysed and compared. The review identified 17 publications containing an incident classification framework. Comparison of factors and themes making up the classification constituent elements revealed some commonality, but no overall consistency, nor evolution towards an ideal framework. Inconsistency arises from differences in the evidential basis and design methodology of classifications, with design itself being an inherently subjective process. It was not possible to identify an 'ideal' incident classification framework for ED risk management, and there is significant variation in the selection of categories used by frameworks. The variation in classification could risk an unbalanced emphasis in findings through application of a particular framework. Design of an ED specific, ideal incident classification framework should be informed by a much wider range of theories of how organisations and systems work, in addition to clinical and human factors.

Artificial neural network modeling enhances risk stratification and can reduce downstream testing for patients with suspected acute coronary syndromes, negative cardiac biomarkers, and normal ECGs

Despite uncertain yield, guidelines endorse routine stress myocardial perfusion imaging (MPI) for patients with suspected acute coronary syndromes, unremarkable serial electrocardiograms, and negative troponin measurements. In these patients, outcome prediction and risk stratification models could spare unnecessary testing. This study therefore investigated the use of artificial neural networks (ANN) to improve risk stratification and prediction of MPI and angiographic results. We retrospectively identified 5354 consecutive patients referred from the emergency department for rest-stress MPI after serial negative troponins and normal ECGs. Patients were risk stratified according to thrombolysis in myocardial infarction (TIMI) scores, ischemia was defined as >5 % reversible perfusion defect, and obstructive coronary artery disease was defined as >50 % angiographic obstruction. For ANN, the network architecture employed a systematic method where the number of neurons is changed incrementally, and bootstrapping was performed to evaluate the accuracy of the models. Compared to TIMI scores, ANN models provided improved discriminatory power. With regards to MPI, an ANN model could reduce testing by 59 % and maintain a 96 % negative predictive value (NPV) for ruling out ischemia. Application of an ANN model could also avoid 73 % of invasive coronary angiograms while maintaining a 98 % NPV for detecting obstructive CAD. An online calculator for clinical use was created using these models. The ANN models improved risk stratification when compared to the TIMI score. Our calculator could also reduce downstream testing while maintaining an excellent NPV, though further study is needed before the calculator can be used clinically.

Missed diagnoses of acute myocardial infarction in the emergency department: variation by patient and facility characteristics

: An estimated 1.2 million people in the US have an acute myocardial infarction (AMI) each year. An estimated 7% of AMI hospitalizations result in death. Most patients experiencing acute coronary symptoms, such as unstable angina, visit an emergency department (ED). Some patients hospitalized with AMI after a treat-and-release ED visit likely represent missed opportunities for correct diagnosis and treatment. The purpose of the present study is to estimate the frequency of missed AMI or its precursors in the ED by examining use of EDs prior to hospitalization for AMI.

: We estimated the rate of probable missed diagnoses in EDs in the week before hospitalization for AMI and examined associated factors. We used Healthcare Cost and Utilization Project State Inpatient Databases and State Emergency Department Databases for 2007 to evaluate missed diagnoses in 111,973 admitted patients aged 18 years and older.

: We identified missed diagnoses in the ED for 993 of 112,000 patients (0.9% of all AMI admissions). These patients had visited an ED with chest pain or cardiac conditions, were released, and were subsequently admitted for AMI within 7 days. Higher odds of having missed diagnoses were associated with being younger and of Black race. Hospital teaching status, availability of cardiac catheterization, high ED admission rates, high inpatient occupancy rates, and urban location were associated with lower odds of missed diagnoses.

: Administrative data provide robust information that may help EDs identify populations at risk of experiencing a missed diagnosis, address disparities, and reduce diagnostic errors.

The impact structured patient assessment frameworks have on patient care: an integrative review

AIMS AND OBJECTIVES

To evaluate structured patient assessment frameworks' impact on patient care.

BACKGROUND

Accurate patient assessment is imperative to determine the status and needs of the patient and the delivery of appropriate patient care. Nurses must be highly skilled in conducting timely and accurate patient assessments to overcome environmental obstacles and deliver quality and safe patient care. A structured approach to patient assessment is widely accepted in everyday clinical practice, yet little is known about the impact structured patient assessment frameworks have on patient care.

DESIGN

Integrative review.

METHODS

An electronic database search was conducted using Cumulative Index to Nursing and Allied Health Literature, Medical Literature Analysis and Retrieval System, PubMed and ProQuest Dissertations and Theses. The reference sections of textbooks and journal articles on patient assessment were manually searched for further studies. A comprehensive peer review screening process was undertaken. Research studies were selected that evaluated the impact structured patient assessment frameworks have on patient care. Studies were included if frameworks were designed for use by paramedics, nurses or medical practitioners working in prehospital or acute in-hospital settings.

RESULTS

Twelve studies met the inclusion criteria. There were no studies that evaluate the impact of a generic nursing assessment framework on patient care. The use of a structured patient assessment framework improved clinician performance of patient assessment. Limited evidence was found to support other aspects of patient care including documentation, communication, care implementation, patient and clinician satisfaction, and patient outcomes.

CONCLUSION

Structured patient assessment frameworks enhance clinician performance of patient assessment and hold the potential to improve patient care and outcomes; however, further research is required to address these evidence gaps, particularly in nursing.

RELEVANCE TO CLINICAL PRACTICE

Acute care clinicians should consider using structured patient assessment frameworks in clinical practice to enhance their performance of patient assessment.

Emergency department crowding and risk of preventable medical errors

The objective of the study is to determine the association between emergency department (ED) crowding and preventable medical errors (PME). This was a retrospective cohort study of 533 ED patients enrolled in the National ED Safety Study (NEDSS) in four Massachusetts EDs. Individual patients' average exposure to ED crowding during their ED visit was compared with the occurrence of a PME (yes/no) for the three diagnostic categories in NEDSS: acute myocardial infarction, asthma exacerbation, and dislocation requiring procedural sedation. To accommodate site-to-site differences in available administrative data, ED crowding was measured using one of three previously validated crowding metrics (ED Work Index, ED Workscore, and ED Occupancy). At each site, the continuous measure was placed into site-specific quartiles, and these quartiles then were combined across sites. We found that 46 (8.6%; 95% confidence interval, 6.4-11.3%) of the 533 patients experienced a PME. For those seen during higher levels of ED crowding (quartile 4 vs. quartile 1), the occurrence of PMEs was more than twofold higher, both on unadjusted analysis and adjusting for two potential confounders (diagnosis, site). The association appeared non-linear, with most PMEs occurring at the highest crowding level. We identified a direct association between high levels of ED crowding and risk of preventable medical errors. Further study is needed to determine the generalizability of these results. Should such research confirm our findings, we would suggest that mitigating ED crowding may reduce the occurrence of preventable medical errors.

An epidemiologic study of closed emergency department malpractice claims in a national database of physician malpractice insurers

OBJECTIVES

The objective was to perform an epidemiologic study of emergency department (ED) medical malpractice claims using data maintained by the Physician Insurers Association of America (PIAA), a trade association whose participating malpractice insurance carriers collectively insure over 60% of practicing physicians in the United States.

METHODS

All closed malpractice claims in the PIAA database between 1985 and 2007, where an event in an ED was alleged to have caused injury to a patient 18 years of age or older, were retrospectively reviewed. Study outcomes were the frequency of claims and average indemnity payments associated with specific errors identified by the malpractice insurer, as well as associated health conditions, primary specialty groups, and injury severity. Indemnity payments include money paid to claimants as a result of settlement or court adjudication, and this financial obligation to compensate a claimant constitutes the insured's financial liability. These payments do not include the expenses associated with resolving a claim, such as attorneys' fees. The study examined claims by adjudicatory outcome, associated financial liability, and expenses of litigation. Adjudicatory outcome refers to the legal disposition of a claim as it makes its way into and through the court system and includes resolution of claims by formal verdict as well as by settlement. The study also investigated how the number of claims, average indemnity payments, paid-to-close ratios (the percentage of closed claims that resolved with a payment to the plaintiff), and litigation expenses have trended over the 23-year study period.

RESULTS

The authors identified 11,529 claims arising from an event originating in an ED, representing over $664 million in total liability over the 23-year study period. Emergency physicians (EPs) were the primary defendants in 19% of ED claims. The largest sources of error, as identified by the individual malpractice insurer, included errors in diagnosis (37%), followed by improper performance of a procedure (17%). In 18% of claims, no error could be identified by the insurer. Acute myocardial infarction (AMI; 5%), fractures (6%), and appendicitis (2%) were the health conditions associated with the highest number of claims. Over two-thirds of claims (70%) closed without payment to the claimant. Most claims that paid out did so through settlement (29%). Only 7% of claims were resolved by verdict, and 85% of those were in favor of the clinician. Over time, the average indemnity payments and expenses of litigation, adjusted for inflation, more than doubled, while both the total number of claims and number of paid claims decreased.

CONCLUSIONS

Emergency physicians were the primary defendants in a relatively small proportion of ED claims. The disease processes associated with the highest numbers of claims included AMI, appendicitis, and fractures. The largest share of overall indemnity was attributed to errors in the diagnostic process. The financial liability of medical malpractice in the ED is substantial, yet the vast majority of claims resolve in favor of the clinician. Efforts to mitigate risk in the ED should include the diverse clinical specialties who work in this complex environment, with attention to those health conditions and potential errors with the highest risk.

Interns overestimate the effectiveness of their hand-off communication

OBJECTIVE

Theories from the psychology of communication may be applicable in understanding why hand-off communication is inherently problematic. The purpose of this study was to assess whether postcall pediatric interns can correctly estimate the patient care information and rationale received by on-call interns during hand-off communication.

METHODS

Pediatric interns at the University of Chicago were interviewed about the hand-off. Postcall interns were asked to predict what on-call interns would report as the important pieces of information communicated during the hand-off about each patient, with accompanying rationale. Postcall interns also guessed on-call interns' rating of how well the hand-offs went. Then, on-call interns were asked to list the most important pieces of information for each patient that postcall interns communicated during the hand-off, with accompanying rationale. On-call interns also rated how well the hand-offs went. Interns had access to written hand-offs during the interviews.

RESULTS

We conducted 52 interviews, which constituted 59% of eligible interviews. Seventy-two patients were discussed. The most important piece of information about a patient was not successfully communicated 60% of the time, despite the postcall intern's believing that it was communicated. Postcall and on-call interns did not agree on the rationales provided for 60% of items. In addition, an item was more likely to be effectively communicated when it was a to-do item (65%) or an item related to anticipatory guidance (69%) compared with a knowledge item (38%). Despite the lack of agreement on content and rationale of information communicated during hand-offs, peer ratings of hand-off quality were high.

CONCLUSIONS

Pediatric interns overestimated the effectiveness of their hand-off communication. Theories from communication psychology suggest that miscommunication is caused by egocentric thought processes and a tendency for the speaker to overestimate the receiver's understanding. This study demonstrates that systematic causes of miscommunication may play a role in hand-off quality.

Residents' and attending physicians' handoffs: a systematic review of the literature

PURPOSE

Effective communication is central to patient safety. There is abundant evidence of negative consequences of poor communication and inadequate handoffs. The purpose of the current study was to conduct a systematic review of articles focused on physicians' handoffs, conduct a qualitative review of barriers and strategies, and identify features of structured handoffs that have been effective.

METHOD

The authors conducted a thorough, systematic review of English-language articles, indexed in PubMed, published between 1987 and June 2008, and focused on physicians' handoffs in the United States. The search strategy yielded 2,590 articles. After title review, 401 were obtained for further review by trained abstractors.

RESULTS

Forty-six articles met inclusion criteria, 33 (71.7%) of which were published between 2005 and 2008. Content analysis yielded 91 handoffs barriers in eight major categories and 140 handoffs strategies in seven major categories. Eighteen articles involved research on handoffs. Quality assessment scores for research studies ranged from 1 to 13 (possible range 1-16). One third of the reviewed research studies obtained quality scores at or below 8, and only one achieved a score of 13. Only six studies included any measure of handoff effectiveness.

CONCLUSIONS

Despite the negative consequences of inadequate physicians' handoffs, very little research has been done to identify best practices. Many of the existing peer-reviewed studies had design or reporting flaws. There is remarkable consistency in the anecdotally suggested strategies; however, there remains a paucity of evidence to support these strategies. Overall, there is a great need for high-quality handoff outcomes studies focused on systems factors, human performance, and the effectiveness of structured protocols and interventions.
