Emergency Physician Knowledge, Attitudes, and Behavior Regarding ACEP's Choosing Wisely Recommendations: A Survey Study

Clinical competence, communication ability and adherence to choosing wisely recommendations for lipid reducing drug use in older adults

BACKGROUND

Although lipid-lowering drugs are not recommended for primary prevention in patients 75+, prevalence of use is high and there is unexplained variation in prescribing between physicians. The objective of this study was to determine if physician communication ability and clinical competence are associated with prescribing lipid-lowering drugs for primary and secondary prevention.

METHODS

We used a cohort of 4,501 international medical graduates, 161,214 U.S. Medicare patients with hyperlipidemia (primary prevention) and 49,780 patients with a history of cardiovascular disease (secondary prevention) not treated with lipid-lowering therapy who were seen by study physicians in ambulatory care. Clinical competence and communication ability were measured by the ECFMG clinical assessment examination. Physician citizenship, age, gender, specialty and patient characteristics were also measured. The outcome was an incident prescription of lipid-lowering drug, evaluated using multivariable GEE logistic regression models for primary and secondary prevention for patients 75+ and 65-74.

RESULTS

Patients 75+ were less likely than those 65-74 to receive lipid-lowering drugs for primary (OR 0.62, 95% CI 0.59-0.66) and secondary (OR 0.70, 95% CI 0.63-0.78) prevention. For every 20% increase in clinical competence score, the odds of prescribing therapy for primary prevention to patients 75+ increased by 24% (95% CI 1.02-1.5). Communication ability had the opposite effect, reducing the odds of prescribing for primary prevention by 11% per 20% score increase (95% CI 0.8-0.99) for both age groups. Physicians who were citizens of countries with higher proportions of Hispanic (South/Central America) or Asian (Asia/Oceania) people were more likely to prescribe treatment for primary prevention, and internal medicine specialists were more likely to treat for secondary prevention than primary care physicians.

CONCLUSION

Clinical competence, communication ability and physician citizenship are associated with lipid-lowering drug prescribing for primary prevention in patients aged 75+.

What works for and what hinders deimplementation of low-value care in emergency medicine practice? A scoping review

OBJECTIVES

Low-value care can harm patients and healthcare systems. Despite a decade of global endeavours, low value care has persisted. Identification of barriers and enablers is essential for effective deimplementation of low-value care. This scoping review is an evidence summary of barriers, enablers and features of effective interventions for deimplementation of low-value care in emergency medicine practice worldwide.

DESIGN

A mixed-methods scoping review was conducted using the Arksey and O'Malley framework.

DATA SOURCES

Medline, CINAHL, Embase, EMCare, Scopus and grey literature were searched from inception to 5 December 2022.

ELIGIBILITY CRITERIA

Primary studies which employed qualitative, quantitative or mixed-methods approaches to explore deimplementation of low-value care in an EM setting and reported barriers, enablers or interventions were included. Reviews, protocols, perspectives, comments, opinions, editorials, letters to editors, news articles, books, chapters, policies, guidelines and animal studies were excluded. No language limits were applied.

DATA EXTRACTION AND SYNTHESIS

Study selection, data collection and quality assessment were performed by two independent reviewers. Barriers, enablers and interventions were mapped to the domains of the Theoretical Domains Framework. The Mixed Methods Appraisal Tool was used for quality assessment.

RESULTS

The search yielded 167 studies. A majority were quantitative studies (90%, 150/167) that evaluated interventions (86%, 143/167). Limited provider abilities, diagnostic uncertainty, lack of provider insight, time constraints, fear of litigation, and patient expectations were the key barriers. Enablers included leadership commitment, provider engagement, provider training, performance feedback to providers and shared decision-making with patients. Interventions included one or more of the following facets: education, stakeholder engagement, audit and feedback, clinical decision support, nudge, clinical champions and training. Multifaceted interventions were more likely to be effective than single-faceted interventions. Effectiveness of multifaceted interventions was influenced by fidelity of the intervention facets. Use of behavioural change theories such as the Theoretical Domains Framework in the published studies appeared to enhance the effectiveness of interventions to deimplement low-value care.

CONCLUSION

High-fidelity, multifaceted interventions that incorporated education, stakeholder engagement, audit/feedback and clinical decision support, were administered daily and lasted longer than 1 year were most effective in achieving deimplementation of low-value care in emergency departments. This review contributes the best available evidence to date, but further rigorous, theory-informed, qualitative and mixed-methods studies are needed to supplement the growing body of evidence to effectively deimplement low-value care in emergency medicine practice.

Management of acute non-specific low back pain in the emergency department: do emergency physicians follow the guidelines? Results of a cross-sectional survey

OBJECTIVES

Clinical guidelines for acute non-specific low back pain (LBP) recommend avoiding imaging studies or invasive treatments and to advise patients to stay active. The aim of this study was to evaluate the management of acute non-specific LBP in the emergency departments (ED).

SETTING

We invited all department chiefs of Swiss EDs and their physician staff to participate in a web-based survey using two clinical case vignettes of patients with acute non-specific LBP presenting to an ED. In both cases, no neurological deficits or red flags were present. Guideline adherence and low-value care was defined based on current guideline recommendations.

RESULTS

In total, 263 ED physicians completed at least one vignette, while 212 completed both vignettes (43% residents, 32% senior/attending physicians and 24% chief physicians). MRI was considered in 31% in vignette 1 and 65% in vignette 2. For pain management, non-steroidal anti-inflammatory drugs, paracetamol and metamizole were mostly used. A substantial proportion of ED physicians considered treatments with questionable benefit and/or increased risk for adverse events such as oral steroids (vignette 1, 12% and vignette 2, 19%), muscle relaxants (33% and 38%), long-acting strong opioids (25% and 33%) and spinal injections (22% and 43%). Although guidelines recommend staying active, 72% and 67% of ED physicians recommended activity restrictions.

CONCLUSION

Management of acute non-specific LBP in the ED was not in agreement with current guideline recommendations in a substantial proportion of ED physicians. Overuse of imaging studies, the use of long-acting opioids and muscle relaxants, as well as recommendations for activity and work restrictions were prevalent and may potentially be harmful.

Exploring emergency physicians’ knowledge, attitudes, and behaviour towards Choosing Wisely in Taiwan

Background

In 2012, the American Board of Internal Medicine Foundation launched the Choosing Wisely campaign to reduce unnecessary care. However, it is unclear how much emergency physicians in Taiwan understand about Choosing Wisely. The purpose of this study was to explore the knowledge, attitude, and behaviour of emergency physicians in Taiwan regarding Choosing Wisely and its related factors; the intention was to identify the baseline knowledge on the basis of which to promote Choosing Wisely in Taiwan.

Methods

This was a cross-sectional study including emergency physicians in Taiwan as research subjects who answered online questionnaires. A 42-item questionnaire was designed according to the Knowledge, Attitude, and Behaviour model (KAB). The questionnaire linkages were delivered to emergency physicians through social media (eg., Line, Facebook) and received assistance from different hospital directors. A total of 162 valid questionnaires were collected. Data analyses include t-test, analysis of variance, chi-square test, Pearson’s correlation, and multivariate linear regression model.

Results

The study determined that although only 38.9% of emergency physicians had heard of Choosing Wisely, the mean correct rate of knowledge score among emergency physicians was 70.1%. Attitude and the behaviour related to Choosing Wisely were positively associated, which means that the more positive the attitude towards Choosing Wisely is, the more positive the behaviour towards Choosing Wisely is. In multiple linear regression analyses, having served as a supervisor, belonging to divisions of health insurance service, and having heard of Choosing Wisely (P < 0.05) positively affect the knowledge of Choosing Wisely, but age presented a negative association.

Conclusion

This study found that physicians’ knowledge does not influence their attitudes and behaviours, which may be related to barriers of practicing Choosing Wisely activities. To effectively promote Choosing Wisely campaign, it is recommended to focus on the significant factors associated with emergency physicians’ perceptions regarding knowledge, attitude, and behavior of Choosing Wisely. Based on these factors, appropriate practice guidelines for Choosing Wisely can be formulated and promoted.

Accuracy of presenting symptoms, physical examination, and imaging for diagnosis of ruptured abdominal aortic aneurysm: Systematic review and meta-analysis

OBJECTIVES

Ruptured abdominal aortic aneurysm (rAAA) is a life-threatening condition, and rapid diagnosis is necessary to facilitate early surgical intervention. We sought to evaluate the accuracy of presenting symptoms, physical examination signs, computed tomography with angiography (CTA), and point-of-care ultrasound (PoCUS) for diagnosis of rAAA.

METHODS

We searched six databases from inception through April 2021. We included studies investigating the accuracy of any of the above tests for diagnosis of rAAA. The primary reference standard used in all studies was intraoperative diagnosis or death from rAAA. Because PoCUS cannot detect rupture, we secondarily assessed its accuracy for the diagnosis of AAA, using the reference standard of intraoperative or CTA diagnosis. We used GRADE to assess certainty in estimates.

RESULTS

We included 20 studies (2,077 patients), with 11 of these evaluating signs and symptoms, seven evaluating CTA, and five evaluating PoCUS. Pooled sensitivities of abdominal pain, back pain, and syncope for rAAA were 61.7%, 53.6%, and 27.8%, respectively (low certainty). Pooled sensitivity of hypotension and pulsatile abdominal mass were 30.9% and 47.1%, respectively (low certainty). CTA had a sensitivity of 91.4% and specificity of 93.6% for diagnosis of rAAA (moderate certainty). In our secondary analysis, PoCUS had a sensitivity of 97.8% and specificity of 97.0% for diagnosing AAA in patients suspected of having rAAA (moderate certainty).

CONCLUSIONS

Classic clinical symptoms associated with rAAA have poor sensitivity, and their absence does not rule out the condition. CTA has reasonable accuracy, but misses some cases of rAAA. PoCUS is a valuable tool that can help guide the need for urgent transfer to a vascular center in patients suspected of having rAAA.

Overuse of medical care in paediatrics: A survey from five countries in the European Academy of Pediatrics

Studies and initiatives such as the "Choosing wisely" (CW) campaign emphasise evidence-based investigations and treatment to avoid overdiagnosis and overtreatment. The perception of the extent of medical overactivity among professionals and drivers behind are not well studied in the paediatric field.

AIM

We aimed to investigate the physicians' opinion and clarify the main drivers regarding medical overactivity in member countries of the European Academy of Paediatrics (EAP).

METHODS

In this study, paediatricians, paediatric residents, primary care paediatricians, and family doctors treating children were surveyed in Norway, Lithuania, Ukraine, Italy, and Switzerland. Over-investigation was defined as "diagnostic work-up or referral that is unlikely to provide information which is relevant for a patient" and overtreatment was defined as "treatment that does not benefit or can harm more than benefit the patient." The original questionnaire was developed in 2018 by a working group from the Norwegian Paediatric Association.

RESULTS

Overall, 1,416 medical doctors participated in the survey, ranging from 144 in Lithuania to 337 in Switzerland. 83% stated that they experienced over-investigation/overtreatment, and 81% perceived this as a problem. The majority (83%) perceived expectations from family and patients as the most important driver for overtreatment in their country. Other drivers for overuse were use of national guidelines/recommendations, worry for reactions, and reduction of uncertainty.

CONCLUSION

This is the first study investigating knowledge and attitude toward medical overactivity in European countries. Despite different cultural and economic environments, the patterns and drivers of increased investigations and medicalisation are similar.

Trends in the Evaluation and Management of Back Pain in Emergency Departments, United States, 2007-2016

OBJECTIVE

Back pain is one of the most common pain syndromes in the United States, but there has been limited recent description of the role of emergency departments (EDs) in caring for patients with back pain. We investigated trends in the evaluation and management of back pain in U.S. EDs from 2007 to 2016.

METHODS

We performed a retrospective analysis of the National Hospital Ambulatory Medical Care Survey, a nationally representative annual survey of ED visits, which includes data on patient-, hospital-, and visit-level characteristics. We evaluated trends among adult ED visits for back pain, including demographics, resource utilization, and disposition. Trends were assessed through the use of survey-weighted analyses.

RESULTS

Visit rates as a proportion of overall ED visits were stable from 2007 to 2016 (9.1% [95% confidence interval (CI): 8.5-9.6] vs. 9.3% [95% CI: 8.6-10.0]; P = 0.44). Admission rates declined from 6.4% (95% CI: 5.1-8.0) to 5.0% (95% CI: 3.5-6.9; P < 0.001). Imaging utilization increased from 51.7% (95% CI: 49.3-54.1) to 57.6% (95% CI: 53.3-61.7; P = 0.023), with an increase of 58.3% in computed tomography. Overall opioid utilization declined from 53.5% (95% CI: 49.4-57.5) to 46.5% (95% CI: 43.2-49.8; P < 0.001). Tramadol use increased over the study period (4.1% [95% CI: 3.0-5.8] vs. 8.4% [95% CI: 6.6-10.7]; P < 0.001).

CONCLUSIONS

Opioid utilization during ED visits for back pain decreased from 2007 to 2016, whereas tramadol use more than doubled. Care intensity increased significantly despite declining admission rates. Further research into optimal strategies for back pain management in the ED is needed.

Determinants for the use and de-implementation of low-value care in health care: a scoping review

BACKGROUND

A considerable proportion of interventions provided to patients lack evidence of their effectiveness. This implies that patients may receive ineffective, unnecessary or even harmful care. However, despite some empirical studies in the field, there has been no synthesis of determinants impacting the use of low-value care (LVC) and the process of de-implementing LVC.

AIM

The aim was to identify determinants influencing the use of LVC, as well as determinants for de-implementation of LVC practices in health care.

METHODS

A scoping review was performed based on the framework by Arksey and O'Malley. We searched four scientific databases, conducted snowball searches of relevant articles and hand searched the journal Implementation Science for peer-reviewed journal articles in English. Articles were included if they were empirical studies reporting on determinants for the use of LVC or de-implementation of LVC. The abstract review and the full-text review were conducted in duplicate and conflicting decisions were discussed until consensus was reached. Data were charted using a piloted data charting form and the determinants were inductively coded and categorised in an iterative process conducted by the project group.

RESULTS

In total, 101 citations were included in the review. Of these, 92 reported on determinants for the use of LVC and nine on determinants for de-implementation. The studies were conducted in a range of health care settings and investigated a variety of LVC practices with LVC medication prescriptions, imaging and screening procedures being the most common. The identified determinants for the use of LVC as well as for de-implementation of LVC practices broadly concerned: patients, professionals, outer context, inner context, process and evidence and LVC practice. The results were discussed in relation to the Consolidated Framework for Implementation Research.

CONCLUSION

The identified determinants largely overlap with existing implementation frameworks, although patient expectations and professionals' fear of malpractice appear to be more prominent determinants for the use and de-implementation of LVC. Thus, existing implementation determinant frameworks may require adaptation to be transferable to de-implementation. Strategies to reduce the use of LVC should specifically consider determinants for the use and de-implementation of LVC.

REGISTRATION

The review has not been registered.

Sociocognitive approach to behaviour change for reducing low-value care

Social and cognitive factors that predispose to low-value care (LVC), and strategies for countering them, may be underarticulated in campaigns aimed at reducing LVC. A sociocognitive approach, in addition to traditional knowledge translation strategies, may augment understanding and changing clinician behaviour underpinning LVC.

Why clinicians overtest: development of a thematic framework

BACKGROUND

Medical tests provide important information to guide clinical management. Overtesting, however, may cause harm to patients and the healthcare system, including through misdiagnosis, false positives, false negatives and overdiagnosis. Clinicians are ultimately responsible for test requests, and are therefore ideally positioned to prevent overtesting and its unintended consequences. Through this narrative literature review and workshop discussion with experts at the Preventing Overdiagnosis Conference (Sydney, 2019), we aimed to identify and establish a thematic framework of factors that influence clinicians to request non-recommended and unnecessary tests.

METHODS

Articles exploring factors affecting clinician test ordering behaviour were identified through a systematic search of MedLine in April 2019, forward and backward citation searches and content experts. Two authors screened abstract titles and abstracts, and two authors screened full text for inclusion. Identified factors were categorised into a preliminary framework which was subsequently presented at the PODC for iterative development.

RESULTS

The MedLine search yielded 542 articles; 55 were included. Another 10 articles identified by forward-backward citation and content experts were included, resulting in 65 articles in total. Following small group discussion with workshop participants, a revised thematic framework of factors was developed: "Intrapersonal" - fear of malpractice and litigation; clinician knowledge and understanding; intolerance of uncertainty and risk aversion; cognitive biases and experiences; sense of medical obligation "Interpersonal" - pressure from patients and doctor-patient relationship; pressure from colleagues and medical culture; "Environment/context" - guidelines, protocols and policies; financial incentives and ownership of tests; time constraints, physical vulnerabilities and language barriers; availability and ease of access to tests; pre-emptive testing to facilitate subsequent care; contemporary medical practice and new technology CONCLUSION: This thematic framework may raise awareness of overtesting and prompt clinicians to change their test request behaviour. The development of a scale to assess clinician knowledge, attitudes and practices is planned to allow evaluation of clinician-targeted interventions to reduce overtesting.

Reducing length of stay for patients presenting to general surgery with acute non-surgical abdominal pain

BACKGROUND

Acute abdominal pain is a common surgical presentation. We previously found that over the last decade, more patients were admitted to hospital with non-surgical diagnoses (e.g. gastroenteritis, constipation and non-specific abdominal pain) and length of stay and use of imaging (mainly computed tomography scan) for these patients increased. This study aimed to reduce length of stay and use of imaging for patients admitted with non-surgical abdominal pain.

METHODS

A prospective study was undertaken in a tertiary centre evaluating length of stay and use of additional imaging in patients with a non-surgical diagnosis after a quality improvement intervention was implemented.

RESULTS

A total of 454 patients were included; 204 (44.9%) presented with non-surgical abdominal pain. During the study period, a significant reduction in computed tomography scan requests was observed (38.5-25.0%, P = 0.037) and an increasing proportion of these patients were discharged within 12 h (33.3-57.1%, P = 0.018). The number of re-presentations remained unchanged (P = 0.358).

CONCLUSIONS

The study intervention increased the proportion of patients with non-surgical diagnoses that were successfully discharged within 12 h and reduced the use of additional imaging in this group. This may lead to improved use of health care resources for patients with more urgent diagnoses.

Choosing wisely in emergency medicine: Early results and insights from the ACEP emergency quality network (E-QUAL)

PURPOSE

To characterize performance among ED sites participating in the Emergency Quality Network (E-QUAL) Avoidable Imaging Initiative for clinical targets on the American College of Emergency Physicians Choosing Wisely list.

METHODS

This was an observational study of quality improvement (QI) data collected from hospital-based ED sites in 2017-2018. Participating EDs reported imaging utilization rates (UR) and common QI practices for three Choosing Wisely targets: Atraumatic Low Back Pain, Syncope, or Minor Head Injury.

RESULTS

305 ED sites participated in the initiative. Among all ED sites, the mean imaging UR for Atraumatic Low Back Pain was 34.7% (IQR 26.3%-42.6%) for XR, 19.1% (IQR 11.4%-24.9%) for CT, and 0.09% (IQR 0%-0.9%) for MRI. The mean CT UR for Syncope was 50.0% (IQR 38.0%-61.4%). The mean CT UR for Minor Head Injury was 72.6% (IQR 65.6%-81.7%). ED sites with sustained participation showed significant decreases in CT UR in 2017 compared to 2018 for Syncope (56.4% vs 48.0%; 95% CI: -12.7%, -4.1%) and Minor Head Injury (76.3% vs 72.1%; 95% CI: -7.3%, -1.1%). There was no significant change in imaging UR for Atraumatic Back Pain for XR (36.0% vs 33.3%; 95% CI: -5.9%, -0;5%), CT (20.1% vs 17.7%; 95% CI: -5.1%, -0.4%) or MRI (0.8% vs 0.7%, 95% CI: -0.4%, -0.3%).

CONCLUSIONS

Early data from the E-QUAL Avoidable Imaging Initiative suggests QI interventions could potentially improve imaging stewardship and reduce low-value care. Further efforts to translate the Choosing Wisely recommendations into practice should promote data-driven benchmarking and learning collaboratives to achieve sustained practice improvement.

A Patient-focused Information Design Intervention to Support the Minor Traumatic Brain Injuries (mTBI) Choosing Wisely Canada Recommendation

Introduction The first Choosing Wisely Canada (CWC) recommendation for Emergency Medicine states: "Don't order CT head scans in adults and children who have suffered minor head injuries (unless positive for a validated head injury clinical decision rule)". In order to provide patients with information on the risks and benefits of computed tomography (CT) scans in minor traumatic brain injuries (mTBI) and to encourage discussions between patients and their doctor, we designed a patient-focused mTBI infographic for the emergency department (ED). Methods Stakeholders worked with content experts to co-design the infographic, which was posted in two emergency department (ED) waiting rooms. A survey was administered to evaluate whether the infographic influenced patient beliefs about the risks and benefits of CT scans and to gauge patient willingness to have a discussion with their doctor about the necessity of a scan. Results One hundred fifteen patients completed the survey. Prior to participating, 38% of patients thought a CT after an mTBI was always a good idea and 60% thought it was sometimes a good idea. After viewing the poster, 87% of respondents stated they better understood when a CT scan may be appropriate, 93% felt they better understood the risks of CT scans, and 76% understood that their doctor can often rule out serious illness without a CT scan. Only 19% of patients still felt that a CT was always necessary after an mTBI. Conclusions The mTBI infographic changed patient perceptions regarding the need for CT scans and increased awareness of the indications and risks of CT scans. This study demonstrates that targeted patient education materials can help support CWC recommendations.

Trends in United States emergency department visits and associated charges from 2010 to 2016

BACKGROUND

Demographic shifts and care delivery system evolution affect the number of Emergency Department (ED) visits and associated costs. Recent aggregate trends in ED visit rates and charges between 2010 and 2016 have not been evaluated.

METHODS

Data from the National Emergency Department Sample, comprising approximately 30 million annual patient visits, were used to estimate the ED visit rate and charges per visit from 2010 to 2016. ED visits were grouped into 144 mutually exclusive clinical categories. Visit rates, compound annual growth rates (CAGRs), and per visit charges were estimated.

RESULTS

From 2010 to 2016, the number of ED visits increased from 128.97 million to 144.82 million; the cumulative growth was 12.29% and the CAGR was 1.95%, while the population grew at a CAGR of 0.73%. Expressed as a population rate, ED visits per 1000 persons increased from 416.92 in 2010 to 448.19 in 2016 (p value <0.001). The mean charges per visit increased from $2061 (standard deviation $2962) in 2010 to $3516 (standard deviation $2962) in 2016; the CAGR was 9.31% (p value <0.001). Of 144 clinical categories, 140 categories had a CAGR for mean charges per visit of at least 5%.

CONCLUSION

The rate of ED visits per 1000 persons and the mean charge per ED visit increased significantly between 2010 and 2016. Mean charges increased for both high- and low-acuity clinical categories. Visits for the 5 most common clinical categories comprise about 30% of ED visits, and may represent focus areas for increasing the value of ED care.

Semistructured interviews regarding patients' perceptions of Choosing Wisely and shared decision-making: an Australian study

OBJECTIVES

This study aimed to examine how patients perceive shared decision-making regarding CT scan referral and use of the five Choosing Wisely questions with their general practitioner (GP).

DESIGN

This is a qualitative exploratory study using semistructured interviews.

SETTING

This study was conducted in a large metropolitan public healthcare organisation in urban Australia.

PARTICIPANTS

Following purposive sampling, 20 patients and 2 carers participated. Patient participants aged 18 years or older were eligible if they were attending the healthcare organisation for a CT scan and referred by their GP. Carers/family were eligible to participate when they were in the role of an unpaid carer and were aged 18 years or older. Participants were required to speak English sufficiently to provide informed consent. Participants with cognitive impairment were excluded.

FINDINGS

Eighteen interviews were conducted with the patient only. Two interviews were conducted with the patient and the patient's carer. Fourteen participants were female. Five themes resulted from the thematic analysis: (1) needing to know, (2) questioning doctors is not necessary, (3) discussing scans is not required, (4) uncertainty about questioning and (5) valuing the Choosing Wisely questions. Participants reported that they presented to their GP with a health problem that they needed to understand and address. Participants accepted their GPs decision to prescribe a CT scan to identify the nature of their problem. They reported ambivalence about engaging in shared decision-making with their doctor, although many participants reported valuing the Choosing Wisely questions.

CONCLUSIONS

Shared decision-making is an important principle underpinning Choosing Wisely. Practice implementation requires understanding patients' motivations to engage in shared decision-making with a focus on attitudes, beliefs, knowledge and emotions. Systems-level support and education for healthcare practitioners in effective communication is important. However, this needs to emphasise communication with patients who have varying degrees of motivation to engage in shared decision-making and Choosing Wisely.

A Broader View of Quality: Choosing Wisely Recommendations From Other Specialties With High Relevance to Emergency Care

STUDY OBJECTIVE

The American College of Emergency Physicians (ACEP) joined the Choosing Wisely campaign in 2013 and has contributed 10 recommendations to reduce low-value care. Recommendations from other specialties may also identify opportunities to improve quality and patient safety in emergency care. The Choosing Wisely work group of the ACEP Quality and Patient Safety Committee seeks to identify and characterize the Choosing Wisely recommendations from other professional societies with the highest relevance to emergency care.

METHODS

In June 2016, all Choosing Wisely recommendations from other specialties were obtained from the American Board of Internal Medicine Foundation. Using a modified Delphi method, the 10 group members rated recommendations for relevance on a validated 7-point scale. Recommendations identified as highly relevant (median score=7) were rated on 3 additional characteristics: cost savings (1=large, 5=none), risk-benefit profile (1=benefit >risk, 5=risk >benefit), and actionability by emergency physicians (1=complete, 5=none). Results are presented as overall means (eg, mean of subcategory means) and subcategory means with SDs.

RESULTS

Initial review of 412 recommendations identified 49 items as highly relevant to emergency care. Eleven were redundant with ACEP recommendations, leaving 38 items from 25 professional societies. Overall means for items ranged from 1.57 to 3.1. Recommendations' scores averaged 3.2 (SD 0.6) for cost savings, 1.9 (SD 0.4) for risk-benefit, and 1.6 (SD 0.5) for actionability. The most common conditions in these recommendations were infectious diseases (14 items; 37%), head injury (4 items; 11%), and primary headache disorders (4 items; 11%). The most frequently addressed interventions were imaging studies (11 items; 29%) and antibiotics (9 items; 24%).

CONCLUSION

Thirty-eight Choosing Wisely recommendations from other specialties are highly relevant to emergency care. Imaging studies and antibiotic use are heavily represented among them.

Baseline Performance of Real-World Clinical Practice Within a Statewide Emergency Medicine Quality Network: The Michigan Emergency Department Improvement Collaborative (MEDIC)

STUDY OBJECTIVE

Large-scale quality and performance measurement across unaffiliated hospitals is an important strategy to drive practice change. The Michigan Emergency Department Improvement Collaborative (MEDIC), established in 2015, has baseline performance data to identify practice variation across 15 diverse emergency departments (EDs) on key emergency care quality indicators.

METHODS

MEDIC is a unique physician-led partnership supported by a major third-party payer. Member sites contribute electronic health record data and trained abstractors add supplementary data for eligible cases. Quality measures include computed tomography (CT) appropriateness for minor head injury, using the Canadian CT Head Rule for adults and Pediatric Emergency Care Applied Network rules for children; chest radiograph use for children with asthma, bronchiolitis, and croup; and diagnostic yield of CTs for suspected pulmonary embolism. Baseline performance was established with statistical process control charts.

RESULTS

From June 1, 2016, to October 31, 2017, the MEDIC registry contained 1,124,227 ED visits, 23.2% for children (<18 years). Overall baseline performance included the following: 40.9% of adult patients with minor head injury (N=11,857) had appropriate CTs (site range 24.3% to 58.6%), 10.3% of pediatric minor head injury cases (N=11,183) exhibited CT overuse (range 5.8% to 16.8%), 38.1% of pediatric patients with a respiratory condition (N=18,190) received a chest radiograph (range 9.0% to 62.1%), and 8.7% of pulmonary embolism CT results (N=16,205) were positive (range 7.5% to 14.3%).

CONCLUSION

Performance varied greatly, with demonstrated opportunity for improvement. MEDIC provides a robust platform for emergency physician engagement across ED practice settings to improve care and is a model for other states.

An Evaluation of Guideline-Discordant Ordering Behavior for CT Pulmonary Angiography in the Emergency Department

PURPOSE

The aim of this study was to determine rates of and possible reasons for guideline-discordant ordering of CT pulmonary angiography for the evaluation of suspected pulmonary embolism (PE) in the emergency department.

METHODS

A retrospective review was performed of 212 consecutive encounters (January 6, 2016, to February 25, 2016) with 208 unique patients in the emergency department that resulted in CT pulmonary angiography orders. For each encounter, the revised Geneva score and two versions of the Wells criteria were calculated. Each encounter was then classified using a two-tiered risk stratification method (PE unlikely versus PE likely). Finally, the rate of and possible explanations for guideline-discordant ordering were assessed via in-depth chart review.

RESULTS

The frequency of guideline-discordant studies ranged from 53 (25%) to 79 (37%), depending on the scoring system used; 46 (22%) of which were guideline discordant under all three scoring systems. Of these, 18 (39%) had at least one patient-specific factor associated with increased risk for PE but not included in the risk stratification scores (eg, travel, thrombophilia).

CONCLUSIONS

Many of the guideline-discordant orders were placed for patients who presented with evidence-based risk factors for PE that are not included in the risk stratification scores. Therefore, guideline-discordant ordering may indicate that in the presence of these factors, the assessment of risk made by current scoring systems may not align with clinical suspicion.

Healthcare professionals' opinions, barriers and facilitators towards low-value clinical practices in the hospital setting

OBJECTIVE

To explore healthcare professionals' opinions about low-value practices, identify practices of this kind possibly present in the hospital and barriers and facilitators to reduce them. Low-value practices include those with little or no clinical benefit that may harm patients or lead to a waste of resources.

METHOD

Using a mixed methodology, we carried out a survey and two focus groups in a tertiary hospital. In the survey, we assessed doctors' agreement, subjective adherence and perception of usefulness of 134 recommendations to reduce low-value practices from local and international initiatives. We also identified low-value practices possibly present in the hospital. In the focus groups with professionals from surgical and medical fields, using a phenomenological approach, we identified additional low-value practices, barriers and facilitators to reduce them.

RESULTS

169 doctors of 25 specialties participated (response rate: 7%-100%). Overall agreement with recommendations, subjective adherence and usefulness were 83%, 90% and 70%, respectively. Low-value practices form 22 recommendations (16%) were considered as possibly present in the hospital. In the focus groups, the professionals identified seven more. Defensive medicine and scepticism due to contradictory evidence were the main barriers. Facilitators included good leadership and coordination between professionals.

CONCLUSIONS

High agreement with recommendations to reduce low-value practices and high perception of usefulness reflect great awareness of low-value care in the hospital. However, there are several barriers to reduce them. Interventions to reduce low-value practices should foster confidence in decision-making processes between professionals and patients and provide trusted evidence.

Overuse of plain abdominal radiography in emergency departments: a retrospective cohort study

BACKGROUND

Plain abdominal radiography (PAR) is routinely performed in emergency departments (EDs). This study aimed to (1) identify the indications for PAR in EDs and compare them against international guidelines, (2) uncover predictors of non-compliance with guidelines, and (3) describe the use of additional radiological examinations in EDs.

METHODS

Retrospective cohort study in the EDs of two hospitals in Geneva, Switzerland, including all adult patients who underwent PAR in the EDs. Indications were considered "appropriate" if complying with guidelines. Predictors of non-compliance were identified by univariate and multivariate analyses.

RESULTS

Over 1 year, PAR was performed in 1997 patients (2.2% of all admissions). Their mean age was 59.7 years, with 53.1% of female patients. The most common indications were constipation (30.8%), suspected ileus (28.9%), and abdominal pain (15.3%). According to the French and American guidelines, only 11.8% of the PARs were indicated, while 46.2% of them complied with the Australian and British guidelines. On multivariate analysis, admission to the private hospital ED (odds ratio [OR] 3.88, 95% CI 1.78-8.45), female gender (OR 1.95, 95% CI 1.46-2.59), and an age >  65 years (OR 2.41, 95%CI 1.74-3.32) were associated with a higher risk of inappropriate PAR. Additional radiological examinations were performed in 73.7% of patients.

CONCLUSIONS

Most indications for PAR did not comply with guidelines and elderly women appeared particularly at risk of being exposed to inappropriate examination. PAR did not prevent the need for additional examinations. Local guidelines should be developed, and initiatives should be implemented to reduce unnecessary PARs.

Use of CT for Head Trauma: 2007-2015

BACKGROUND AND OBJECTIVES

International efforts have been focused on identifying children at low risk of clinically important traumatic brain injury in whom computed tomography (CT) neuroimaging can be avoided. We sought to determine if CT use for pediatric head trauma has decreased among US emergency departments (EDs).

METHODS

This was a cross-sectional analysis of the National Hospital Ambulatory Care Medical Survey database of nationally representative ED visits from 2007 to 2015. We included children <18 years of age evaluated in the ED for head injury. Survey weighting procedures were used to estimate the annual proportion of children who underwent CT neuroimaging and to perform multivariable logistic regression.

RESULTS

There were an estimated 14.3 million pediatric head trauma visits during the 9-year study period. Overall, 32% (95% confidence interval [CI]: 29%-35%) of children underwent CT neuroimaging with no significant annual linear trend (P trend = .50). Multivariate analysis similarly revealed no difference by year (adjusted odds ratio [aOR]: 1.02; 95% CI: 0.97-1.07) after adjustment for patient- and ED-level covariates. CT use was associated with age ≥2 years (aOR: 1.51; 95% CI: 1.13-2.01), white race (aOR: 1.43; 95% CI: 1.10-1.86), highest triage acuity (aOR: 8.24 [95% CI: 4.00-16.95]; P < .001), and presentation to a nonteaching (aOR: 1.47; 95% CI: 1.05-2.06) or nonpediatric (aOR: 1.53; 95% CI: 1.05-2.23) hospital.

CONCLUSIONS

CT neuroimaging did not decrease from 2007 to 2015. Findings suggest an important need for quality improvement initiatives to decrease CT use among children with head injuries.

National Estimates of Emergency Department Visits for Antibiotic Adverse Events Among Adults-United States, 2011-2015

BACKGROUND

Detailed, nationally representative data describing high-risk populations and circumstances involved in antibiotic adverse events (AEs) can inform approaches to prevention.

OBJECTIVE

Describe US burden, rates, and characteristics of emergency department (ED) visits by adults for antibiotic AEs.

DESIGN

Nationally representative, public health surveillance of adverse drug events (National Electronic Injury Surveillance System-Cooperative Adverse Drug Event Surveillance [NEISS-CADES]) and a nationally projected database of dispensed prescriptions (QuintilesIMS), 2011-2015.

PATIENTS

Antibiotic-treated adults (≥ 20 years) seeking ED care.

MAIN MEASURES

Estimated annual numbers and rates of ED visits for antibiotic AEs among outpatients treated with systemically administered antibiotics.

KEY RESULTS

Based on 10,225 cases, US adults aged ≥ 20 years made an estimated 145,490 (95% confidence interval, 115,279-175,701) ED visits for antibiotic AEs each year in 2011-2015. Antibiotics were implicated in 13.7% (12.3-15.2%) of all estimated adult ED visits for adverse drug events. Most (56.6%; 54.8-58.4%) antibiotic AE visits involved adults aged < 50 years, and 71.8% (70.4-73.1%) involved females. Accounting for prescriptions dispensed from retail and long-term care pharmacies, adults aged 20-34 years had twice the estimated rate of ED visits for oral antibiotic AEs compared with those aged ≥ 65 years (9.7 [7.6-11.8] versus 4.6 [3.6-5.7] visits per 10,000 dispensed prescriptions, respectively). Allergic reactions accounted for three quarters (74.3%; 70.0-78.6%) of estimated ED visits for antibiotic AEs. The three most frequently implicated antibiotic classes in ED visits for antibiotic AEs were oral sulfonamides (23.2%; 20.6-25.8%), penicillins (20.8%; 19.3-22.4%), and quinolones (15.7%; 14.2-17.1%). Per-prescription rates declined with increasing age group.

CONCLUSIONS

Antibiotics are a common cause of ED visits by adults for adverse drug events and represent an important safety issue. Quantifying risks of AEs from specific antibiotics for specific patient populations, such as younger adults, provides additional information to help clinicians assess risks versus benefits when making the decision to prescribe or not prescribe an antibiotic. AE rates may also facilitate communication with patients about antibiotic risks.

Appropriateness of CT scans for patients with non-traumatic acute abdominal pain

OBJECTIVE

Acute abdominal pain is the most common reason for surgical admission. CT scans are increasingly used to aid early diagnosis. Excessive use of CT scans is associated with increased length of stay, healthcare costs and radiation. The aim of this study was to evaluate the appropriateness of CT scans for patients presenting with acute abdominal pain.

METHODS

We examined 100 consecutive patients presenting with new acute abdominal pain who underwent a CT scan. Clinical information available at the time the scan was ordered, was summarised and reviewed independently by five consultant general surgeons and five consultant radiologists.

RESULTS

A CT scan was judged to be not indicated in a median of 21% of cases (range 12-53%), more information was required in a median of 16% (0-41%) and in a median of 58% (37-88%) the CT scan was considered indicated. There was a good level of agreement (Cronbach's α 0.704) across the 10 experts.

CONCLUSION

These data suggest that a large proportion of CT scans for patients with acute abdominal pain are not clinically indicated or are being performed prior to adequate clinical work-up. Optimising CT scan requests for this patient group will improve use of healthcare resources. Advances in knowledge: Both radiologists and general surgeons agree that there is no indication for an abdominal CT scan for a patient presenting with acute abdominal pain in a median of 21% of the cases.

Choosing Wisely Campaign: Valuable For Providers Who Knew About It, But Awareness Remained Constant, 2014-17

Together with physician specialty societies, the Choosing Wisely® campaign has codified recommendations of which health care services' use should be questioned and discussed with patients. The ABIM Foundation administered surveys in 2014 and 2017 to examine physicians' attitudes toward and awareness of the use of low-value care. The surveys included questions on the factors driving that use, physicians' comfort in having conversations with patients about that use, and physicians' exposure to the Choosing Wisely campaign. Despite continued publicity and physician outreach efforts, there were no significant changes between 2014 and 2017 in awareness of the campaign among physicians (awareness increased from 21 percent to 25 percent) or physician-reported difficulty in talking to patients about avoiding a low-value service (42 percent reported that such conversations had gotten harder in 2014, and 46 percent did so in 2017). Barriers to the adoption of recommendations included malpractice concerns, patient demand and satisfaction, and physicians' desire for more information to reduce uncertainty. Multifaceted interventions that reinforce guidelines through personalized education, follow-up, and feedback, as well as aligned financial incentives, should be pursued to reduce the use of low-value services.
