Accuracy of the Emergency Severity Index triage instrument for identifying elder emergency department patients receiving an immediate life-saving intervention.

OBJECTIVES The study objective was to determine the sensitivity and specificity of the Emergency Severity Index (ESI) triage instrument for the identification of elder patients receiving an immediate life-saving intervention in the emergency department (ED). METHODS The authors reviewed medical records for consecutive patients 65 years or older who presented to a single academic ED serving a large community of elders during a 1-month period. ESI triage scores were compared to actual ED course with attention to the occurrence of an immediate life-saving intervention. The sensitivity and specificity of an ESI triage level of 1 for the identification of patients receiving an immediate intervention was calculated. For 50 cases, the triage nurse ESI designation was compared to the triage level determined by an expert triage nurse based on retrospective record review. RESULTS Of 782 consecutive patients 65 years or older who presented to the ED, 18 (2%) had an ESI level of 1, 176 (23%) had an ESI level of 2, 461 (60%) had an ESI level of 3, 100 (13%) had an ESI level of 4, and 18 (2%) had an ESI level of 5. Twenty-six patients received an immediate life-saving intervention. ESI triage scores for these 26 individuals were as follows: ESI 1, 11 patients; ESI 2, nine patients; and ESI 3, six patients. The sensitivity of ESI to identify patients receiving an immediate intervention was 42.3% (95% confidence interval [CI]=23.3% to 61.3%); the specificity was 99.2% (95% CI=98.0% to 99.7%). For 17 of 50 cases in which actual triage nurse and expert nurse ESI levels disagreed, undertriage by the triage nurses was more common than overtriage (13 vs. 4 patients). CONCLUSIONS The ESI triage instrument identified fewer than half of elder patients receiving an immediate life-saving intervention. Failure to follow established ESI guidelines in the triage of elder patients may contribute to apparent undertriage.

Predicting hospital admission and returns to the emergency department for elderly patients.

OBJECTIVES Methods to accurately identify elderly patients with a high likelihood of hospital admission or subsequent return to the emergency department (ED) might facilitate the development of interventions to expedite the admission process, improve patient care, and reduce overcrowding. This study sought to identify variables found among elderly ED patients that could predict either hospital admission or return to the ED. METHODS All visits by patients 75 years of age or older during 2007 at an academic ED serving a large community of elderly were reviewed. Clinical and demographic data were used to construct regression models to predict admission or ED return. These models were then validated in a second group of patients 75 and older who presented during two 1-month periods in 2008. RESULTS Of 4,873 visits, 3,188 resulted in admission (65.4%). Regression modeling identified five variables statistically related to the probability of admission: age, triage score, heart rate, diastolic blood pressure, and chief complaint. Upon validation, the c-statistic of the receiver operating characteristic (ROC) curve was 0.73, moderately predictive of admission. We were unable to produce models that predicted ED return for these elderly patients. CONCLUSIONS A derived and validated triage-based model is presented that provides a moderately accurate probability of hospital admission of elderly patients. If validated experimentally, this model might expedite the admission process for elderly ED patients. Our models failed, as have others, to accurately predict ED return among elderly patients, underscoring the challenge of identifying those individuals at risk for early ED returns.

Predictive Value of Initial Triage Vital Signs for Critically Ill Older Adults

Introduction: Triage of patients is critical to patient safety, yet no clear information exists as to the utility of initial vital signs in identifying critically ill older emergency department (ED) patients. The objective of this study is to evaluate a set of initial vital sign thresholds as predictors of severe illness and injury among older adults presenting to the ED. Methods: We reviewed all visits by patients aged 75 and older seen during 2007 at an academic ED serving a large community of older adults. Patients’ charts were abstracted for demographic and clinical information including vital signs, via automated electronic methods. We used bivariate analysis to investigate the relationship between vital sign abnormalities and severe illness or injury, defined as intensive care unit (ICU) admission or ED death. In addition, we calculated likelihood ratios for normal and abnormal vital signs in predicting severe illness or injury. Results: 4,873 visits by patients aged 75 and above were made to the ED during 2007, and of these 3,848 had a complete set of triage vital signs. For these elderly patients, the sensitivity and specificity of an abnormal vital sign taken at triage for predicting death or admission to an ICU were 73% (66,81) and 50% (48,52) respectively (positive likelihood ratio 1.47 (1.30,1.60); negative likelihood ratio 0.54 (0.30,0.60). Conclusion: Emergency provider assessment and triage scores that rely primarily on initial vital signs are likely to miss a substantial portion of critically ill older adults.

Using screen-based simulation to improve performance during pediatric resuscitation.

OBJECTIVES To assess the ability of a screen-based simulation-training program to improve emergency medicine and pediatric resident performance in critical pediatric resuscitation knowledge, confidence, and skills. METHODS A pre-post, interventional design was used. Three measures of performance were created and assessed before and after intervention: a written pre-course knowledge examination, a self-efficacy confidence score, and a skills-based high-fidelity simulation code scenario. For the high-fidelity skills assessment, independent physician raters recorded and reviewed subject performance. The intervention consisted of eight screen-based pediatric resuscitation scenarios that subjects had 4 weeks to complete. Upon completion of the scenarios, all three measures were repeated. For the confidence assessment, summary pre- and post-test summary confidence scores were compared using a t-test, and for the skills assessment, pre-scores were compared with post-test measures for each individual using McNemars chi-square test for paired samples. RESULTS Twenty-six of 35 (71.3%) enrolled subjects completed the institutional review board-approved study. Increases were observed in written test scores, confidence, and some critical interventions in high-fidelity simulation. The mean improvement in cumulative confidence scores for all residents was 10.1 (SD +/-4.9; range 0-19; p < 0.001), with no resident feeling less confident after the intervention. Although overall performance in simulated codes did not change significantly, with average scores of 6.65 (+/-1.76) to 7.04 (+/-1.37) out of 9 possible points (p = 0.58), improvement was seen in the administering of appropriate amounts of IV fluids (59-89%, p = 0.03). CONCLUSIONS In this study, improvements in resident knowledge, confidence, and performance of certain skills in simulated pediatric cardiac arrest scenarios suggest that screen-based simulations may be an effective way to enhance resuscitation skills of pediatric providers. These results should be confirmed using a randomized design with an appropriate control group.

Nursing home revenue source and information availability during the emergency department evaluation of nursing home residents.

OBJECTIVES Lack of access to medical information for nursing home residents during emergency department (ED) evaluation is a barrier to quality care. We hypothesized that the quantity of information available in the ED differs based on the funding source of the residents nursing home. DESIGN Cross-sectional observational study. SETTING Single academic ED. PARTICIPANTS Participants were 128 skilled nursing facility (SNF) residents age 65 or older from 12 SNFs. MEASUREMENTS Emergency physicians documented knowledge of 9 essential information items. SNFs were categorized as accepting or not accepting Medicaid. RESULTS Questionnaires were completed for 128 patients, of whom 95 (74%) were from 1 of 8 Medicaid-funded SNFs and 33 (26%) were from 1 of 4 SNFs not accepting Medicaid. Patients from SNFs accepting Medicaid were younger (79 versus 87, P < .001) and less frequently white (62% versus 97%, P < .001). The mean number of 9 possible information items available was lower for patients from SNFs that accept Medicaid (7.13 versus 8.15, P < .001). Emergency providers also reported lower satisfaction regarding access to information for residents from SNFs that accept Medicaid (P < .05). The association between residence in an SNF that accepts Medicaid and lower ED information scores remained after linear regression with clustering by SNF controlling for age, gender, and race. The most common source of information for residents from both types of SNFs was transfer papers from the SNF. CONCLUSION Less information is available to ED providers for patients from SNFs that accept Medicaid than for residents from SNFs that do not accept Medicaid. Further study is needed to examine this information gap.

Computer‐facilitated Review of Electronic Medical Records Reliably Identifies Emergency Department Interventions in Older Adults

OBJECTIVES An estimated 14% to 25% of all scientific studies in peer-reviewed emergency medicine (EM) journals are medical records reviews. The majority of the chart reviews in these studies are performed manually, a process that is both time-consuming and error-prone. Computer-based text search engines have the potential to enhance chart reviews of electronic emergency department (ED) medical records. The authors compared the efficiency and accuracy of a computer-facilitated medical record review of ED clinical records of geriatric patients with a traditional manual review of the same data and describe the process by which this computer-facilitated review was completed. METHODS Clinical data from consecutive ED patients age 65 years or older were collected retrospectively by manual and computer-facilitated medical record review. The frequency of three significant ED interventions in older adults was determined using each method. Performance characteristics of each search method, including sensitivity and positive predictive value, were determined, and the overall sensitivities of the two search methods were compared using McNemars test. RESULTS For 665 patient visits, there were 49 (7.4%) Foley catheters placed, 36 (5.4%) sedative medications administered, and 15 (2.3%) patients who received positive pressure ventilation. The computer-facilitated review identified more of the targeted procedures (99 of 100, 99%), compared to manual review (74 of 100 procedures, 74%; p < 0.0001). CONCLUSIONS A practical, non-resource-intensive, computer-facilitated free-text medical record review was completed and was more efficient and accurate than manually reviewing ED records.

Toward a new paradigm: goal-based residency training.

OBJECTIVES Many factors affect the clinical training experience of emergency medicine (EM) residents, and length of training currently serves as a proxy for clinical experience. Very few studies have been published that provide quantitative information about clinical experience. The goals of this study were to determine the numbers of clinical encounters for each resident in emergency department (ED) rotations during training in a 3-year program, to characterize these encounters by patient acuity and age, to determine the numbers of encounters for selected clinical disorders, and to assess the variation in clinical experience between residents. METHODS This was a retrospective analysis of the ED clinical and administrative databases at two hospitals that provide EM training for a southeastern U.S. EM residency program. Data were gathered for three complete cohorts of residents, with entering years of 2003, 2004, and 2005, so the total study period was 2003-2008. ED clinical encounter information included hospital training site (tertiary or community), postgraduate year (PGY) of the resident, patient triage acuity reflected by the Emergency Severity Index (ESI); patient International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic code; and patient age group. RESULTS There were 25 residents with 120,240 total ED clinical encounters from 2003 to 2008. The median number of ED clinical encounters for a resident during his or her training was 4,836 (range = 3,831 to 5,780), based on a maximum of an 80-hour work week, and 24 or 25 four-week blocks of EM rotations. Overall, clinical encounters increased by 30% from PGY 1 to PGY 2, and another 14% from PGY 2 to PGY 3. There was 30% to 60% variation in clinical encounters between individual residents. Variability was most prominent in the care of children and in the care of time-sensitive critical illness. Resident encounters with lower-acuity problems during training were much less than the anticipated lower-acuity burden during practice. Additionally, residents did not encounter some high-risk conditions clinically during the study period. CONCLUSIONS Methods should be developed to decrease resident variance in both numbers and types of clinical encounters and to provide curriculum supplementation for individuals and for the entire residency cohort in areas that are important for the clinical practice of EM, but that are rare or not encountered during residency training.

Implementation of a Web-based system to improve the transitional care of older adults.

We constructed a bidirectional Web-based system to transmit critical patient information in real time between referring nursing homes and a university hospital emergency department (ED) to facilitate the care of patients referred to our ED. Our model was inexpensive, improved measures of information transfer, and increased provider satisfaction.

Shared Decision Making to Improve the Emergency Care of Older Adults: A Research Agenda

Older emergency department patients have high rates of serious illness and injury, are at high risk for side effects and adverse events from treatments and diagnostic tests, and in many cases, have nuanced goals of care in which pursuing the most aggressive approach is not desired. Although some forms of shared decision making (SDM) are commonly practiced by emergency physicians caring for older adults, broader use of SDM in this setting is limited by a lack of knowledge of the types of patients and conditions for which SDM is most helpful and the approaches and tools that can best facilitate this process. We describe a research agenda to generate new knowledge to optimize the use of SDM during the emergency care of older adults.

Telephone Follow‐Up for Older Adults Discharged to Home from the Emergency Department: A Pragmatic Randomized Controlled Trial

Telephone calls after discharge from the emergency department (ED) are increasingly used to reduce 30‐day rates of return or readmission, but their effectiveness is not established. The objective was to determine whether a scripted telephone intervention by registered nurses from a hospital‐based call center would decrease 30‐day rates of return to the ED or hospital or of death.
