The association between emergency department crowding and analgesia administration in acute abdominal pain patients

Better performance on length-of-stay benchmarks associated with reduced risk following emergency department discharge: an observational cohort study

Introduction

Emergency department (ED) crowding is associated with adverse outcomes. Several jurisdictions have established benchmarks and targets for length-of-stay (LOS) to reduce crowding. An evaluation has been conducted on whether performance on Ontario’s ED LOS benchmarks is associated with reduced risk of death or hospitalization.

Methods

A retrospective cohort study of discharged ED patients was conducted using population-based administrative data from Ontario (April 2008 to February 2012). For each ED visit, the proportion of patients seen during the same shift that met ED LOS benchmarks was determined. Performance was categorized as <80%, 80% to <90%, 90% to <95%, and 95%–100% of same-shift ED patients meeting the benchmark. Logistic regression models analysed the association between performance on ED LOS benchmarks and 7-day death or hospitalization, controlled for patient and ED characteristics and stratified by patient acuity.

Results

From 122 EDs, 2,295,256 high-acuity and 1,626,629 low-acuity visits resulting in discharge were included. Deaths and hospitalizations within 7 days totalled 1,429 (0.062%) and 49,771 (2.2%) among high-acuity, and 220 (0.014%) and 9,005 (0.55%) among low-acuity patients, respectively. Adverse outcomes generally increased among patients seen during shifts when a lower proportion of ED patients met ED LOS benchmarks. The adjusted odds ratios (and 95% confidence intervals) among high- and low-acuity patients seen on shifts when <80% met ED benchmarks (compared with ≥95%) were, respectively, 1.32 (1.05–1.67) and 1.84 (1.21–2.81) for death, and 1.13 (1.08–1.17) and 1.40 (1.31–1.49) for hospitalization.

Conclusions

Better performance on Ontario’s ED LOS benchmarks for each shift is associated with a 10%–45% relative reduction in the odds of death or admission 7 days after ED discharge.

Opioid analgesia for acute abdominal pain in children: A systematic review and meta-analysis

OBJECTIVES

There are long-held concerns that analgesia in patients with acute abdominal pain may obscure the physical examination and lead to missing a diagnosis of appendicitis. Despite evidence to the contrary, analgesia continues to be underutilized and suboptimally dosed in children with acute abdominal pain. The objective of this systematic review and meta-analysis was to determine if opioids provide analgesia without an increase in side effects and appendicitis-related complications.

METHODS

Trials were identified through electronic searches of MEDLINE (1946-2013), EMBASE (1980-2013), Cochrane Central Register of Controlled Trials (2013), CINAHL (1981-2013), and Google Scholar (2013). All randomized controlled trials (RCTs) of children aged 0-18 years with acute abdominal pain that compared any opioid analgesic to placebo were included. The methodologic qualities of studies and the overall quality of evidence were evaluated using the Cochrane Collaboration's Risk of Bias tool and the Grading of Recommendations Assessment, Development, and Evaluation system, respectively.

RESULTS

Six RCTs met inclusion criteria, and each compared a single-dose parenteral opioid to a placebo, providing data on 342 children aged 5 to 18 years. The pooled mean pre/post difference in self-reported pain scores was 19.61 mm (95% confidence interval [CI] = -1.16 to 40.37 mm) lower in those receiving opioid analgesia. There was no significant increase in the risk of perforation or abscess associated with opioids in cases of appendicitis (relative risk [RR] = 1.03, 95% CI = 0.55 to 1.93). The risk of side effects was significantly greater in patients who received opioids (RR = 6.06, 95% CI = 1.10 to 33.49). Subtherapeutic dosing of opioids was detected in all six trials.

CONCLUSIONS

The use of opioids in undifferentiated acute abdominal pain in children is associated with no difference in pain scores and an increased risk of mild side effects. However, there is no increased risk of perforation or abscess. The overall quality of evidence is low, suggesting the need for larger, high-quality trials that are powered to detect both serious complications of appendicitis and determine the most efficacious opioid dosing for children.

Effects of emergency department expansion on emergency department patient flow

OBJECTIVES

Emergency department (ED) crowding is an increasing problem associated with adverse patient outcomes. ED expansion is one method advocated to reduce ED crowding. The objective of this analysis was to determine the effect of ED expansion on measures of ED crowding.

METHODS

This was a retrospective study using administrative data from two 11-month periods before and after the expansion of an ED from 33 to 53 adult beds in an academic medical center. ED volume, staffing, and hospital admission and occupancy data were obtained either from the electronic health record (EHR) or from administrative records. The primary outcome was the rate of patients who left without being treated (LWBT), and the secondary outcome was total ED boarding time for admitted patients. A multivariable robust linear regression model was used to determine whether ED expansion was associated with the outcome measures.

RESULTS

The mean (±SD) daily adult volume was 128 (±14) patients before expansion and 145 (±17) patients after. The percentage of patients who LWBT was unchanged: 9.0% before expansion versus 8.3% after expansion (difference = 0.6%, 95% confidence interval [CI] = -0.16% to 1.4%). Total ED boarding time increased from 160 to 180 hours/day (difference = 20 hours, 95% CI = 8 to 32 hours). After daily ED volume, low-acuity area volume, daily wait time, daily boarding hours, and nurse staffing were adjusted for, the percentage of patients who LWBT was not independently associated with ED expansion (p = 0.053). After ED admissions, ED intensive care unit (ICU) admissions, elective surgical admissions, hospital occupancy rate, ICU occupancy rate, and number of operational ICU beds were adjusted for, the increase in ED boarding hours was independently associated with the ED expansion (p = 0.005).

CONCLUSIONS

An increase in ED bed capacity was associated with no significant change in the percentage of patients who LWBT, but had an unintended consequence of an increase in ED boarding hours. ED expansion alone does not appear to be an adequate solution to ED crowding.

Treatment of acute abdominal pain in the emergency room: a systematic review of the literature

Appropriate pain therapy prior to diagnosis in patients with acute abdominal pain remains controversial. Several recent studies have demonstrated that pain therapy does not negatively influence either the diagnosis or subsequent treatment of these patients; however, current practice patterns continue to favour withholding pain medication prior to diagnosis and surgical treatment decision. A systematic review of PubMed, Web-of-Science and The-Cochrane-Library from 1929 to 2011 was carried out using the key words of 'acute', 'abdomen', 'pain', 'emergency' as well as different pain drugs in use, revealed 84 papers. The results of the literature review were incorporated into six sections to describe management of acute abdominal pain: (1) Physiology of Pain; (2) Common Aetiologies of Abdominal Pain; (3) Pre-diagnostic Analgesia; (4) Pain Therapy for Acute Abdominal Pain; (5) Analgesia for Acute Abdominal Pain in Special Patient Populations; and (6) Ethical and Medico-legal Considerations in Current Analgesia Practices. A comprehensive algorithm for analgesia for acute abdominal pain in the general adult population was developed. A review of the literature of common aetiologies and management of acute abdominal pain in the general adult population and special patient populations seen in the emergency room revealed that intravenous administration of paracetamol, dipyrone or piritramide are currently the analgesics of choice in this clinical setting. Combinations of non-opioids and opioids should be administered in patients with moderate, severe or extreme pain, adjusting the treatment on the basis of repeated pain assessment, which improves overall pain management.

Suitability of emergency department attenders to be assessed in primary care: survey of general practitioner agreement in a random sample of triage records analysed in a service evaluation project

OBJECTIVES

To assess the proportion of emergency department (ED) attendances that would be suitable for primary care and the inter-rater reliability of general practitioner (GP) assessment of primary care suitability.

DESIGN OF STUDY

Survey of GPs' agreement of suitability for primary care on a random anonymised sample of all ED patients attending over a 1-month period.

SETTING

ED of a UK Hospital serving a population of 600 000.

METHOD

Four GPs independently used data extracted from clinical notes to rate the appropriateness for management in primary care as well as need for investigations, specialist review or admission. Agreement was assessed using Cohen's κ.

RESULTS

The mean percentage of patients that GPs considered suitable for primary care management was 43% (range 38-47%). The κ for agreement was 0.54 (95% CI 0.44 to 0.64) and 0.47(95% CI 0.38 to 0.59). In patients deemed not suitable for primary care, GPs were more likely to determine the need for specialist review (relative risks (RR)=3.5, 95% CI 3.0 to 4.2, p<0.001) and admission (RR=3.9, 95% CI 3.2 to 4.7, p<0.001). In patients assessed as suitable for primary care, GPs would initiate investigations in 51% of cases. Consensus over primary care appropriateness was higher for paediatric than for adult attenders.

CONCLUSIONS

A significant number of patients attending ED could be managed by GPs, including those requiring investigations at triage. A stronger agreement among GPs over place of care may be seen for paediatric than for adult attenders. More effective signposting of patients presenting with acute or urgent problems and supporting a greater role for primary care in relieving the severe workflow pressures in ED in the UK are potential solutions.

Overuse of computed tomography pulmonary angiography in the evaluation of patients with suspected pulmonary embolism in the emergency department

BACKGROUND

Clinical decision rules have been developed and validated for the evaluation of patients presenting with suspected pulmonary embolism (PE) to the emergency department (ED).

OBJECTIVES

The objective was to assess the percentage of computed tomographic pulmonary angiography (CT-PA) procedures that could have been avoided by use of the Wells score coupled with D-dimer testing (Wells/D-dimer) or pulmonary embolism rule-out criteria (PERC) in ED patients with suspected PE.

METHODS

The authors conducted a prospective cohort study of adult ED patients undergoing CT-PA for suspected PE. Wells score and PERC were calculated. A research blood sample was obtained for D-dimer testing for subjects who did not undergo testing as part of their ED evaluation. The primary outcome was PE by CT-PA or 90-day follow-up. Secondary outcomes were ED length of stay (LOS) and CT-PA time as defined by time from order to initial radiologist interpretation.

RESULTS

Of 152 suspected PE subjects available for analysis (mean ± SD age = 46.3 ± 15.6 years, 74% female, 59% black or African American, 11.8% diagnosed with PE), 14 (9.2%) met PERC, none of whom were diagnosed with PE. A low-risk Wells score (≤4) was assigned to 110 (72%) subjects, of whom only 38 (35%) underwent clinical D-dimer testing (elevated in 33/38). Of the 72 subjects with low-risk Wells scores who did not have D-dimers performed in the ED, archived research samples were negative in 16 (22%). All 21 subjects with low-risk Wells scores and negative D-dimers were PE-negative. CT-PA time (median = 160 minutes) accounted for more than half of total ED LOS (median = 295 minutes).

CONCLUSIONS

In total, 9.2 and 13.8% of CT-PA procedures could have been avoided by use of PERC and Wells/D-dimer, respectively.

Predictive variables of an emergency department quality and performance indicator: a 1-year prospective, observational, cohort study evaluating hospital and emergency census variables and emergency department time interval measurements

OBJECTIVE

Emergency department (ED) crowding impacts negatively on quality of care. The aim was to determine the association between ED quality and input, throughput and output-associated variables.

METHODS

This 1-year, prospective, observational, cohort study determined the daily percentage of patients leaving the ED in <4 h (ED quality and performance indicator; EDQPI). According to the median EDQPI two groups were defined: best-days and bad-days. Hospital and ED variables and time interval metrics were evaluated as predictors.

RESULTS

Data were obtained for 67 307 patients over 364 days. Differences were observed between the two groups in unadjusted analysis: number of daily visits, number of patients as a function of final disposition, number boarding in the ED, and time interval metrics including wait time to triage nurse and ED provider, time from ED admission to decision, time from decision to departure and length of stay (LOS) as a function of final disposition. Five variables remained significant predictors for bad-days in multivariate analysis: wait time to triage nurse (OR 2.36; 95% CI 1.36 to 4.11; p=0.002), wait time to ED provider (OR 1.93; 95% CI 1.05 to 3.54; p=0.03), number of patients admitted to hospital (OR 1.86; 95% CI 1.09 to 3.19; p=0.02), LOS of non-admitted patients (OR 9.5; 95% CI 5.17 to 17.48; p<0.000001) and LOS of patients admitted to hospital (OR 2.46; 95% CI 1.44 to 4.2; p=0.0009).

CONCLUSIONS

Throughput is the major determinant of EDQPI, notably time interval reflecting the work dynamics of medical and nursing teams and the efficacy of fast-track routes for low-complexity patients. Output also significantly impacted on EDQPI, particularly the capacity to reduce the LOS of admitted patients.

Selection and validation of quality indicators for the Shorter Stays in Emergency Departments National Research Project

OBJECTIVE

Despite the spread of time targets for ED lengths of stay around the world, there have been few studies exploring the effects of such policies on quality of ED care. The Shorter Stays in Emergency Departments (SSED) National Research Project seeks to address this. The purpose of this paper was to describe how the indicators for the SSED study in New Zealand were selected and validated.

METHODS

A literature review was used to identify potential indicators. A reference group of 25 key stakeholders from across the health system was convened, with the aims of validating the suggested indicators and to ensure that other candidate indicators were not overlooked. A thematic analysis using a general inductive approach was used to analyse focus group discussions.

RESULTS

The major themes were communication, access, timeliness, appropriateness and satisfaction. The 12 indicators selected after literature review were confirmed and two further indicators added after the thematic analysis. The indicators are: hospital and ED length of stay; re-presentation within 48 h; mortality; times to reperfusion, antibiotics, asthma treatment, analgesia, CT for head injury and to theatre (appendicitis and fractured neck of femur); triage time compliance; proportion who left without being seen; quality of discharge information; and ED overcrowding/access block.

CONCLUSION

Through literature review and consultation with stakeholders, an evidence-based and clinically relevant set of indicators was compiled with which to measure the effect of the SSED target. This indicator set is consistent with recent international recommendations for measuring quality of care in EDs.

Implementing performance improvement in New Zealand emergency departments: the six hour time target policy national research project protocol

BACKGROUND

In May 2009, the New Zealand government announced a new policy aimed at improving the quality of Emergency Department care and whole hospital performance. Governments have increasingly looked to time targets as a mechanism for improving hospital performance and from a whole system perspective, using the Emergency Department waiting time as a performance measure has the potential to see improvements in the wider health system. However, the imposition of targets may have significant adverse consequences. There is little empirical work examining how the performance of the wider hospital system is affected by such a target. This project aims to answer the following questions: How has the introduction of the target affected broader hospital performance over time, and what accounts for these changes? Which initiatives and strategies have been successful in moving hospitals towards the target without compromising the quality of other care processes and patient outcomes? Is there a difference in outcomes between different ethnic and age groups? Which initiatives and strategies have the greatest potential to be transferred across organisational contexts?

METHODS/DESIGN

The study design is mixed methods; combining qualitative research into the behaviour and practices of specific case study hospitals with quantitative data on clinical outcomes and process measures of performance over the period 2006-2012. All research activity is guided by a Kaupapa Māori Research methodological approach. A dynamic systems model of acute patient flows was created to frame the study. Consequences of the target (positive and negative) will be explored by integrating analyses and insights gained from the quantitative and qualitative streams of the study.

DISCUSSION

At the time of submission of this protocol, the project has been underway for 12 months. This time was necessary to finalise both the case study sites and the secondary outcomes through key stakeholder consultation. We believe that this is an appropriate juncture to publish the protocol, now that the sites and final outcomes to be measured have been determined.

Association of emergency department length of stay with safety-net status

CONTEXT

Performance measures, particularly pay for performance, may have unintended consequences for safety-net institutions caring for disproportionate shares of Medicaid or uninsured patients.

OBJECTIVE

To describe emergency department (ED) compliance with proposed length-of-stay measures for admissions (8 hours or 480 minutes) and discharges, transfers, and observations (4 hours or 240 minutes) by safety-net status.

DESIGN, SETTING, AND PARTICIPANTS

The 2008 National Hospital Ambulatory Medical Care Survey (NHAMCS) ED data were stratified by safety-net status (Centers for Disease Control and Prevention definition) and disposition (admission, discharge, observation, transfer). The 2008 NHAMCS is a national probability sample of 396 hospitals (90.2% unweighted response rate) and 34 134 patient records. Visits were excluded for patients younger than 18 years, missing length-of-stay data or dispositions of missing, other, left against medical advice, or dead on arrival. Median and 90th percentile ED lengths of stay were calculated for each disposition and admission/discharge subcategories (critical care, psychiatric, routine) stratified by safety-net status. Multivariable analyses determined associations with length-of-stay measure compliance.

MAIN OUTCOME MEASURES

Emergency Department length-of-stay measure compliance by disposition and safety-net status.

RESULTS

Of the 72.1% ED visits (N = 24 719) included in the analysis, 42.3% were to safety-net EDs and 57.7% were to non-safety-net EDs. The median length of stay for safety-net was 269 minutes (interquartile range [IQR], 178-397 minutes) for admission vs 281 minutes (IQR, 178-401 minutes) for non-safety-net EDs; 156 minutes (IQR, 95-239 minutes) for discharge vs 148 minutes (IQR, 88-238 minutes); 355 minutes (IQR, 221-675 minutes) for observations vs 298 minutes (IQR, 195-440 minutes); and 235 minutes (IQR, 155-378 minutes) for transfers vs 239 minutes (IQR, 142-368 minutes). Safety-net status was not independently associated with compliance with ED length-of-stay measures; the odds ratio was 0.83 for admissions (95% CI, 0.52-1.34); 1.03 for discharges (95% CI, 0.83-1.27); 1.05 for observations (95% CI, 0.57-1.95), 1.30 for transfers (95% CI, 0.70-2.45]); or subcategories except for psychiatric discharges (1.67, [95% CI, 1.02-2.74]).

CONCLUSION

Compliance with proposed ED length-of-stay measures for admissions, discharges, transfers, and observations did not differ significantly between safety-net and non-safety-net hospitals.

Time to take stock: a meta-analysis and systematic review of analgesic treatment disparities for pain in the United States

BACKGROUND

The recent Institute of Medicine Report assessing the state of pain care in the United States acknowledged the lack of consistent data to describe the nature and magnitude of unrelieved pain and identify subpopulations with disproportionate burdens.

OBJECTIVES

We synthesized 20 years of cumulative evidence on racial/ethnic disparities in analgesic treatment for pain in the United States. Evidence was examined for the 1) magnitude of association between race/ethnicity and analgesic treatment; 2) subgroups at an increased risk; and 3) the effect of moderators (pain type, setting, study quality, and data collection period) on this association.

METHODS

United States studies with at least one explicit aim or analysis comparing analgesic treatment for pain between Whites and a minority group were included (SciVerse Scopus database, 1989-2011).

RESULTS

Blacks/African Americans experienced both a higher number and magnitude of disparities than any other group in the analyses. Opioid treatment disparities were ameliorated for Hispanics/Latinos for "traumatic/surgical" pain (P = 0.293) but remained for "non-traumatic/nonsurgical" pain (odds ratio [OR] = 0.70, 95% confidence interval [CI] = 0.64-0.77, P = 0.000). For Blacks/African Americans, opioid prescription disparities were present for both types of pain and were starker for "non-traumatic/nonsurgical" pain (OR = 0.66, 95% CI = 0.59-0.75, P = 0.000). In subanalyses, opioid treatment disparities for Blacks/African Americans remained consistent across pain types, settings, study quality, and data collection periods.

CONCLUSION

Our study quantifies the magnitude of analgesic treatment disparities in subgroups of minorities. The size of the difference was sufficiently large to raise not only normative but quality and safety concerns. The treatment gap does not appear to be closing with time or existing policy initiatives. A concerted strategy is needed to reduce pain care disparities within the larger quality of care initiatives.

Emergency department crowding is associated with decreased quality of analgesia delivery for children with pain related to acute, isolated, long-bone fractures

OBJECTIVES

The authors sought to determine which quality measures of analgesia delivery are most influenced by emergency department (ED) crowding for pediatric patients with long-bone fractures.

METHODS

This cross-sectional, retrospective study included patients 0-21 years seen for acute, isolated long-bone fractures, November 2007 to October 2008, at a children's hospital ED. Nine quality measures were studied: six were based on the timeliness (1-hour receipt) and effectiveness (receipt/nonreceipt) of three fracture-related processes: pain score, any analgesic, and opioid analgesic administration. Three equity measures were also tested: language, identified primary care provider (PCP), and insurance. The primary independent variable was a crowding measure: ED occupancy. Models were adjusted for age, language, insurance, identified PCP, triage level, ambulance arrival, and time of day. The adjusted risk of each timeliness or effectiveness quality measure was measured at five percentiles of crowding and compared to the risk at the 10th and 90th percentiles. The role of equity measures as moderators of the crowding-quality models was tested.

RESULTS

The study population included 1,229 patients. Timeliness and effectiveness quality measures showed an inverse association with crowding-an effect not moderated by equity measures. Patients were 4% to 47% less likely to receive timely care and were 3% to 17% less likely to receive effective care when each crowding measure was at the 90th than at the 10th percentile (p < 0.05). For three of the six quality measures, quality declined steeply between the 75th and 90th crowding percentiles.

CONCLUSIONS

Crowding is associated with decreased timeliness and effectiveness, but not equity, of analgesia delivery for children with fracture-related pain.

Interventions to improve patient-centered care during times of emergency department crowding

Patient-centered care is defined by the Institute of Medicine (IOM) as care that is responsive to individual patient needs and values and that guides treatment decisions. This article is the result of a breakout session of the 2011 Academic Emergency Medicine consensus conference "Interventions to Assure Quality in the Crowded Emergency Department" and focuses on three broad domains of patient-centered care: patient satisfaction, patient involvement, and care related to patient needs.The working group provided background information and an overview of interventions that have been conducted in the domains of patient satisfaction, patient involvement (patients' preferences and values in decision-making), and patient needs (e.g., comfort, information, education). Participants in the breakout session discussed interventions reported in the medical literature as well as initiated at their institutions, discussed the effect of crowding on patient-centered care, and prioritized, in a two-step voting process, five areas of focus for establishing a research agenda for studying patient-centered care during times of crowding. The research priorities for enhancing patient-centered care in all three domains during periods of crowding are discussed. These include assessing the effect of other quality domains on patient satisfaction and determining the effects of changes in ED operations on patient satisfaction; enhancing patient involvement by determining the effect of digital records and health information technology (HIT); rapid assessment areas with focused patient-provider communication; and meeting patients' needs through flexible staffing, use of HIT to enhance patient communication, discharge instructions, and postdischarge telephone calls.

Achieving efficiency in crowded emergency departments: a research agenda

In 2011, Academic Emergency Medicine convened a consensus conference entitled "Interventions to Assure Quality in the Crowded Emergency Department." This article, a product of the breakout session on "interventions to safeguard efficiency of care," explores various elements of the research agenda on efficiency and quality in crowded emergency departments (EDs). The authors discuss four areas identified as critical to achieving progress in the research agenda for improving ED efficiency: 1) What measures can be used to understand and improve the efficiency and quality of interventions in the ED? 2) Which factors outside of the ED's control affect ED efficiency? 3) How do workforce factors affect ED efficiency? 4) How do ED design, patient flow structures, and use of technology affect efficiency? Filling these knowledge gaps is vital to identifying interventions that improve the delivery of emergency care in all EDs.

The association between length of emergency department boarding and mortality

OBJECTIVES

Emergency department (ED) boarding has been associated with several negative patient-oriented outcomes, from worse satisfaction to higher inpatient mortality rates. The current study evaluates the association between length of ED boarding and outcomes. The authors expected that prolonged ED boarding of admitted patients would be associated with higher mortality rates and longer hospital lengths of stay (LOS).

METHODS

This was a retrospective cohort study set at a suburban academic ED with an annual ED census of 90,000 visits. Consecutive patients admitted to the hospital from the ED and discharged between October 2005 and September 2008 were included. An electronic medical record (EMR) system was used to extract patient demographics, ED disposition (discharge, admit to floor), ED and hospital LOS, and in-hospital mortality. Boarding was defined as ED LOS 2 hours or more after decision for admission. Descriptive statistics were used to evaluate the association between length of ED boarding and hospital LOS, subsequent transfer to an intensive care unit (ICU), and mortality controlling for comorbidities.

RESULTS

There were 41,256 admissions from the ED. Mortality generally increased with increasing boarding time, from 2.5% in patients boarded less than 2 hours to 4.5% in patients boarding 12 hours or more (p < 0.001). Mean hospital LOS also showed an increase with boarding time (p < 0.001), from 5.6 days (SD ± 11.4 days) for those who stayed in the ED for less than 2 hours to 8.7 days (SD ± 16.3 days) for those who boarded for more than 24 hours. The increases were still apparent after adjustment for comorbid conditions and other factors.

CONCLUSIONS

Hospital mortality and hospital LOS are associated with length of ED boarding.

Transvaginal evisceration progressing to peritonitis in the emergency department: a case report

Background

Abdominal pain is a common complaint among emergency department patients, making it essential to identify those with life-threatening etiologies. We report on the rare finding of atraumatic transvaginal bowel evisceration in a patient presenting to the emergency department with the primary complaint of abdominal pain.

Case Description

A 63-year-old female presented ambulatory to the emergency department with abdominal pain and foreign body sensation in her vagina after coughing. Physical exam demonstrated evisceration of her small bowel through her vagina. During her clinical course, she rapidly deteriorated from appearing well without abdominal tenderness to hypotensive with frank peritonitis.

Conclusion

This case demonstrates the need to perform a thorough physical exam on all patients with abdominal pain and details the management of vaginal evisceration. This case also highlights the difficulty of appropriate triage for patients with complaints not easily assessed in triage. In an era of emergency department crowding, emergency physicians should reevaluate nursing education on triaging abdominal pain to prevent delays in caring for well-appearing patients who have underlying life-threatening illnesses.

Educational excellence in a crowded emergency department: consensus recommendations from the council of emergency medicine residency directors 2010

OBJECTIVE

Emergency Department (ED) crowding is a major public health problem and one that has not been well studied for its effects on education. The objective of this article was to identify best-practice, consensus recommendations to help emergency medicine (EM) residency programs and faculty maintain educational excellence in an era of ED crowding.

METHODS

A geographically diverse group of 37 clinician-educator leaders in EM convened at the 2010 Council of Emergency Medicine Residency Directors Academic Assembly. The participants discussed innovative ideas and solutions to address the many educational challenges that ED crowding poses.

RESULTS

To cope with crowding, the consensus group identified 3 educational domains, focusing on the educator, the learner, and the institutional system. Core subthemes included optimizing teaching opportunities, providing alternative teaching approaches, and redefining what faculty and learners traditionally think of as teaching. An ED rotation provides ample opportunities for teaching not only about patient care and medical knowledge but also other Accreditation Council for Graduate Medical Education competencies, such as interpersonal and communication skills, professionalism, and system-based practice.

CONCLUSIONS

Crowding in EDs poses educational challenges, but with some creativity, flexibility, and desire to make the most of a challenging situation, educational excellence is an achievable goal.

The effect of emergency department crowding on length of stay and medication treatment times in discharged patients with acute asthma

OBJECTIVES

This study sought to determine if emergency department (ED) crowding was associated with longer ED length of stay (LOS) and time to ordering medications (nebulizers and steroids) in patients treated and discharged with acute asthma and to study how delays in ordering may affect the relationship between ED crowding and ED LOS.

METHODS

A retrospective cohort study was performed in adult ED patients aged 18 years and older with a primary International Classification of Diseases, 9th Revision (ICD-9), diagnosis of asthma who were treated and discharged from two EDs from January 1, 2007, to January 1, 2009. Four validated measures of ED crowding (ED occupancy, waiting patients, admitted patients, and patient-hours) were assigned at the time of triage. The associations between the level of ED crowding and overall LOS and time to treatment orders were tested by analyzing trends across crowding quartiles, testing differences between the highest and lowest quartiles using Hodges-Lehmann distances, and using relative risk (RR) regression for multivariable analysis.

RESULTS

A total of 1,716 patients were discharged with asthma over the study period (932 at the academic site and 734 at the community site). LOS was longer at the academic site than the community site for asthma patients by 90 minutes (95% confidence interval [CI] = 79 to 101 minutes). All four measures of ED crowding were associated with longer LOS and time to treatment order at both sites (p < 0.001). At the highest level of ED occupancy, patients spent 75 minutes (95% CI = 58 to 93 minutes) longer in the ED compared to the lowest quartile of ED occupancy. In addition, comparing the highest and lowest quartiles of ED occupancy, time to nebulizer order was 6 minutes longer (95% CI = 1 to 13 minutes), and time to steroid order was 16 minutes longer (95% CI = 0 to 38 minutes). In the multivariable analysis, the association between ED crowding and LOS remained significant. Delays in nebulizer and steroid orders explained some, but not all, of the relationship between ED crowding and ED LOS.

CONCLUSIONS

Emergency department crowding is associated with longer ED LOS (by more than 1 hour) in patients who ultimately get discharged with asthma flares. Some but not all of longer LOS during crowded times is explained by delays in ordering asthma medications.

Emergency department throughput, crowding, and financial outcomes for hospitals

Emergency department (ED) crowding has been identified as a major public health problem in the United States by the Institute of Medicine. ED crowding not only is associated with poorer patient outcomes, but it also contributes to lost demand for ED services when patients leave without being seen and hospitals must go on ambulance diversion. However, somewhat paradoxically, ED crowding may financially benefit hospitals. This is because ED crowding allows hospitals to maximize occupancy with well-insured, elective patients while patients wait in the ED. In this article, the authors propose a more holistic model of hospital flow and revenue that contradicts this notion and offer suggestions for improvements in ED and hospital management that may not only reduce crowding and improve quality, but also increase hospital revenues. Also proposed is that increased efficiency and quality in U.S. hospitals will require changes in systematic microeconomic and macroeconomic incentives that drive the delivery of health services in the United States. Finally, the authors address several questions to propose mutually beneficial solutions to ED crowding that include the realignment of hospital incentives, changing culture to promote flow, and several ED-based strategies to improve ED efficiency.

Patient Weight as a Predictor of Pain Response to Morphine in the Emergency Department

Study Objectives: There is little evidence that patient weight is associated with pain response to morphine in the emergency department (ED). The primary outcome of this study is to identify demographic variables including patient weight that are associated with an adequate pain reduction after the first dose of morphine. Methods: A retrospective chart review of all patients with severe nontraumatic abdominal pain receiving intravenous morphine was conducted in our ED over a 3-month time period. Pain score, using an 11-point verbal numerical pain scale (0-10), was measured before and after each dose of morphine. Adequate response was defined as a ≥ 4-point reduction from baseline pain score. Results: A total of 105 patients were included in the analysis. Univariate logistic regression analyses stratified by dose (2 or 4 mg) showed that patient weight was not predictive of adequate pain response after the first dose of morphine (2 mg: odds ratio = 1; 95% confidence interval 0.97-1.03; P = .88; 4 mg: odds ratio = 1; 95% confidence interval 0.97-1.03; P = .86). Conclusions: Patient weight may not predict pain response to morphine in the ED. Dosing strategies based on patient weight may not be necessary in this patient population.

The effect of emergency department crowding on analgesia in patients with back pain in two hospitals

OBJECTIVES

The authors assessed the association between measures of emergency department (ED) crowding and treatment with analgesia and delays to analgesia in ED patients with back pain.

METHODS

This was a retrospective cohort study of nonpregnant patients who presented to two EDs (an academic ED and a community ED in the same health system) from July 1, 2003, to February 28, 2007, with a chief complaint of "back pain." Each patient had four validated crowding measures assigned at triage. Main outcomes were the use of analgesia and delays in time to receiving analgesia. Delays were defined as greater than 1 hour to receive any analgesia from the triage time and from the room placement time. The Cochrane-Armitage test for trend, the Cuzick test for trend, and relative risk (RR) regression were used to test the effects of crowding on outcomes.

RESULTS

A total of 5,616 patients with back pain presented to the two EDs over the study period (mean+/-SD age=44+/-17 years, 57% female, 62% black or African American). Of those, 4,425 (79%) received any analgesia while in the ED. A total of 3,589 (81%) experienced a delay greater than 1 hour from triage to analgesia, and 2,985 (67%) experienced a delay more than 1 hour from room placement to analgesia. When hospitals were analyzed separately, a higher proportion of patients experienced delays at the academic site compared with the community site for triage to analgesia (87% vs. 74%) and room to analgesia (71% vs. 63%; both p<0.001). All ED crowding measures were associated with a higher likelihood for delays in both outcomes. At the academic site, patients were more likely to receive analgesia at the highest waiting room numbers. There were no other differences in ED crowding and likelihood of receiving medications in the ED at the two sites. These associations persisted in the adjusted analysis after controlling for potential confounders of analgesia administration.

CONCLUSIONS

As ED crowding increases, there is a higher likelihood of delays in administration of pain medication in patients with back pain. Analgesia administration was not related to three measures of ED crowding; however, patients were actually more likely to receive analgesics when the waiting room was at peak levels in the academic ED.

Percentage of US emergency department patients seen within the recommended triage time: 1997 to 2006

BACKGROUND

The wait time to see a physician in US emergency departments (EDs) is increasing and may differentially affect patients with varied insurance status and racial/ethnic backgrounds.

METHODS

Using a stratified random sampling of 151 999 visits, representing 539 million ED visits from 1997 to 2006, we examined trends in the percentage of patients seen within the triage target time by triage category (emergent, urgent, semiurgent, and nonurgent), payer type, and race/ethnicity.

RESULTS

The percentage of patients seen within the triage target time declined a mean of 0.8% per year, from 80.0% in 1997 to 75.9% in 2006 (P < .001). The percentage of patients seen within the triage target time declined 2.3% per year for emergent patients (59.2% to 48.0%; P < .001) compared with 0.7% per year for semiurgent patients (90.6% to 84.7%; P < .001). In 2006, the adjusted odds of being seen within the triage target time were 30% lower than in 1997 (odds ratio, 0.70; 95% confidence interval, 0.55-0.89). The adjusted odds of being seen within the triage target time were 87% lower (odds ratio, 0.13; 95% confidence interval, 0.11-0.15) for emergent patients compared with semiurgent patients. Patients of each payment type experienced similar decreases in the percentage seen within the triage target over time (P for interaction = .24), as did patients of each racial/ethnic group (P = .05).

CONCLUSIONS

The percentage of patients in the ED who are seen by a physician within the time recommended at triage has been steadily declining and is at its lowest point in at least 10 years. Of all patients in the ED, the most emergent are the least likely to be seen within the triage target time. Patients of all racial/ethnic backgrounds and payer types have been similarly affected.
