Writing the Curriculum Vitae and Personal Statement.

Two of the most important components of the medical student's application for the National Resident Matching Program are the curriculum vitae (CV) and personal statement (PS). The aim of the CV is to give an itemized account of the applicant's accomplishments since the beginning of their undergraduate studies, with the main emphasis on their activities and performance in medical school. The PS, on the other hand, is the applicant's chance to give program directors (PDs) a sense of who they are. The purpose of the PS is to complement but not rehash the CV. It is an opportunity to convey what makes them fit for a residency in emergency medicine (EM). A well-written statement should guide the reader through the heartbreaks, triumphs, and inspirations that drive the applicant. Applicants should remember that the CV and PS are the first impression they brand. Both the CV and PS should be brief; easy to read; professional; honest; consistent; and free of clichés, spelling mistakes, and grammatical errors.

Prospective correlation of arterial vs venous blood gas measurements in trauma patients.

OBJECTIVE: The objective of this study is to assess if venous blood gas (VBG) results (pH and base excess [BE]) are numerically similar to arterial blood gas (ABG) in acutely ill trauma patients. METHODS: We prospectively correlated paired ABG and VBG results (pH and BE) in adult trauma patients when ABG was clinically indicated. A priori consensus threshold of clinical equivalence was set at ± less than 0.05 pH units and ± less than 2 BE units. We hypothesized that ABG results could be predicted by VBG results using a regression equation, derived from 173 patients, and validated on 173 separate patients. RESULTS: We analyzed 346 patients and found mean arterial pH of 7.39 and mean venous pH of 7.35 in the derivation set. Seventy-two percent of the paired sample pH values fell within the predefined consensus equivalence threshold of ± less than 0.05 pH units, whereas the 95% limits of agreement (LOAs) were twice as wide, at -0.10 to 0.11 pH units. Mean arterial BE was -2.2 and venous BE was -1.9. Eighty percent of the paired BE values fell within the predefined ± less than 2 BE units, whereas the 95% LOA were again more than twice as wide, at -4.4 to 3.9 BE units. Correlations between ABG and VBG were strong, at r(2) = 0.70 for pH and 0.75 for BE. CONCLUSION: Although VBG results do correlate well with ABG results, only 72% to 80% of paired samples are clinically equivalent, and the 95% LOAs are unacceptably wide. Therefore, ABG samples should be obtained in acutely ill trauma patients if accurate acid-base status is required.

The worsening of ED on-call coverage in California: 6-year trend.

To reassess problems with on-call physician coverage in California, we repeated our anonymous 2000 survey of the California chapter of the American College of Emergency Physicians. Physicians responded from 77.4% of California emergency departments (EDs), 51.0% of ED directors, and 34% of those surveyed. Of 21 specialties, on-call availability worsened since 2000 for 9, was unchanged for 11, and improved for 1. Of ED directors, 54% report medical staff rules require on-call duty, down from 72% in 2000. Hospitals have increased specialist on-call payments (from 21% to 35%, with 75% paying at least one specialty). Most emergency physicians (80.3%) report insurance status negatively affects on-call physician responsiveness, up from 42% in 2000. Emergency departments with predominantely minority or uninsured patients had fewer specialists and more trouble accessing them. Insurance status has a major negative effect on ED consultation and follow-up care. The on-call situation in California has worsened substantially in 6 years.

Personal digital assistants change management more often than paper texts and foster patient confidence.

INTRODUCTION: Rapid retrieval of information, including drug treatment options, is critical to emergency department practice. OBJECTIVES: To assess feasibility and patient acceptance of personal digital assistants and to determine the scope of management changes. METHODS: Emergency medicine residents (EMRs, n = 18) and emergency medicine attending (EMAs, n = 12) used personal digital assistants with drug database and clinical references. Text versions were also available in the emergency department. We did a prospective, random, cross-over time-motion study, recording retrieval time, source, and changes to patient care for 16 and 8 h for EMRs and EMAs, respectively. We surveyed patients for confidence in EMRs and EMAs with personal digital assistants, and perceived efficiency. RESULTS: EMRs accessed paper (n = 131) or personal digital assistant (n = 181) information on 92.3% of patients (n = 17, both). They accessed personal digital assistant on 61.4% of patients vs. 44.5% with texts (odds ratio 1.99, 95% confidence interval 1.4-2.80). Mean access times were 9.3 and 9.4 s, respectively, +1.4 for both. Personal digital assistant access was 75%/25% between pharmacopeia and clinical resource. Personal digital assistants changed drug choice in 39/181 patients (21.5%), and other management (diagnosis, treatment or disposition) in 15/181 patients (8.3%). Odds ratio for change in management for personal digital assistant vs. paper was 2.00 (95% confidence interval 1.11-3.60). We surveyed patient perception for 198 of 295 patients (67.1%). Fifty percent reported more confidence in their EMRs and EMAs with a personal digital assistant, while 5% reported less confidence. Sixty percent agreed strongly that there is too much medical information to remember. CONCLUSIONS: Personal digital assistants are feasible in an academic emergency department and change management more often than texts. EMRs accessed personal digital assistants more often than paper texts. Patient perceptions of physicians who use personal digital assistants are neutral or favorable.

Defining "therapeutically inconsequential" head computed tomographic findings in patients with blunt head trauma.

STUDY OBJECTIVE: Many injuries detected by computed tomographic (CT) imaging of blunt head trauma patients are considered "therapeutically inconsequential." We estimate the prevalence of these findings and determine how frequently affected patients had "important neurosurgical outcomes," defined as either a directed intervention or a poor Glasgow Outcome Scale score. METHODS: We prospectively enrolled all blunt head trauma patients undergoing emergency head CT imaging at 18 centers participating in the National Emergency X-radiography Utilization Study II (NEXUS). From these cases, we identified all patients whose official CT reading met predefined criteria for "therapeutically inconsequential" injuries. We obtained detailed follow-up information on all such patients at 6 sites, including the need for neurosurgical intervention and Glasgow Outcome Scale scores. Among patients having "important neurosurgical outcomes," we assessed the frequency of 2 potential clinical identifiers: altered mental status and coagulopathy. RESULTS: "Therapeutically inconsequential" head CT findings were present in 155 of 8,374 subjects (1.85%; 95% confidence interval 1.57% to 2.16%). Sites participating in the follow-up study enrolled 81 of these patients, of whom 10 (12%) had "important neurosurgical outcomes." Follow-up information was available for 9 patients, all of whom had abnormal mental status at CT scanning. Coagulopathy was also present in 5 of 7 patients for whom coagulation status was known. CONCLUSION: "Therapeutically inconsequential" findings are identified in less than 2% of blunt head trauma patients who undergo CT scanning. A small proportion of these patients have an "important neurosurgical outcome," but it appears that such patients may be identified clinically by the presence of abnormal mental status or coagulopathy.

Can ED staff accurately estimate the weight of adult patients?

PURPOSE: The purpose of the study was to determine the accuracy of adult weight estimates by emergency department personnel. BASIC PROCEDURES: This was a prospective, nonrandomized, observational study in a university tertiary referral center. All patient care staff and all adult patients were eligible. Patients were weighed at the bedside, then staff were asked individually for estimates. Data were analyzed using SPSS general linear modeling procedures (SPSS, Chicago, IL) to obtain a generalized analysis of variance. MAIN FINDINGS: Eighty-seven staff provided 957 estimates on 241 patients. Providers were within 5% of true weight on 33% of estimates (95% confidence interval [CI], 28-38). In our a priori subgroups, a significant difference was noted only for body mass index (BMI); percentages of correct estimates were 16% (95% CI, 0-33; n = 33) for BMI < 18.5; 38% (95% CI, 33-43; n = 654) for 18.5 < or = BMI < or = 30; and 23% (95% CI, 17-30; n = 270) for BMI > 30 (P < .001). PRINCIPAL CONCLUSIONS: Emergency department personnel provided accurate weights in only 33% of estimates. Estimates became significantly less accurate in underweight and obese patients (defined by BMI).

Performance of a decision rule to predict need for computed tomography among children with blunt head trauma.

OBJECTIVE: To assess the ability of the NEXUS II head trauma decision instrument to identify patients with clinically important intracranial injury (ICI) from among children with blunt head trauma. METHODS: An analysis was conducted of the pediatric cohort involved in the derivation set of National Emergency X-Radiography Utilization Study II (NEXUS II), a prospective, observational, multicenter study of all patients who had blunt head trauma and underwent cranial computed tomography (CT) imaging at 1 of 21 emergency departments. We determined the test performance characteristics of the 8-variable NEXUS II decision instrument, derived from the entire NEXUS II cohort, in the pediatric cohort (0-18 years of age), as well as in the very young children (<3 years). Clinically important ICI was defined as ICI that required neurosurgical intervention (craniotomy, intracranial pressure monitoring, or mechanical ventilation) or was likely to be associated with significant long-term neurologic impairment. RESULTS: NEXUS II enrolled 1666 children, 138 (8.3%) of whom had clinically important ICI. The decision instrument correctly identified 136 of the 138 cases and classified 230 as low risk. A total of 309 children were younger than 3 years, among whom 25 had ICI. The decision instrument identified all 25 cases of clinically important ICI in this subgroup. CONCLUSIONS: The decision instrument derived in the large NEXUS II cohort performed with similarly high sensitivity among the subgroup of children who were included in this study. Clinically important ICI were rare in children who did not exhibit at least 1 of the NEXUS II risk criteria.

Epidemiology of blunt head injury victims undergoing ED cranial computed tomographic scanning.

STUDY OBJECTIVE: We sought to describe the epidemiology of emergency department (ED) patients with blunt head injury undergoing cranial computed tomography (CT) scanning for the evaluation of possible traumatic brain injury (TBI). METHODS: Prospective, multicenter, observational study of ED patients undergoing cranial CT after blunt head injury. Patient's date of birth, sex, and race/ethnicity were documented before CT scanning. Individual patients were considered to have "significant" TBI if the official radiographic interpretation at the end of all imaging studies associated with the trauma was consistent with any of a set of predefined diagnoses. The relative prevalence of TBI among various prespecified groups from those undergoing cranial CT scanning was also calculated. RESULTS: Of 13728 patients who were enrolled, 8988 (65%) were men and 1193 (8.7%) had a significant acute TBI. Demographic findings associated with increased risk of TBI, among patients selected for scanning, included the following: age below 10 years (relative risk [RR] = 1.44, 95% confidence interval [CI], 1.19-1.77); age above 65 years (RR = 1.59; 95% CI, 1.40-1.80), and male sex (RR = 1.27; 95% CI, 1.30-1.43). CONCLUSION: Among patients selected for cranial CT scanning after blunt head injury, men, patients younger than 10 years, and those older than 65 years have an increased likelihood of significant TBI.

The Frequency of Reevaluation or Peak Flow Meter Documentation in Acute Asthma Exacerbations in the Emergency Department: Are We Treating in Accordance with NIH/NAEPP Guidelines?

OBJECTIVES: To evaluate the frequency of peak expiratory flow rate (PEFR) measurement and clinical re-evaluation in the management of ED asthmatic patients. METHODS: This was a retrospective chart review examining consecutive asthma patients who presented to the University of California Irvine ED between September 1, 2003 and December 31, 2003. Patients were excluded if they had a diagnosis of COPD, lung cancer, pneumonia, congestive heart failure, alpha 1 anti-trypsin deficiency or were under 5 years of age. Data collected included patient demographics, pulse oximetry reading(s), ED treatments rendered, and frequencies of PEFR measurement (pre and post therapy), of clinical re-evaluations in the ED, and of ED return visits. RESULTS: Of the 122 ED visits from 111 patients, 11 (10%) patients returned during the 4 month study period, with 5 patients (4.5%) returning in less than 72 hours. Seven (6.0%) patients had PEFR done both pre and post treatment and 24 (20%) had one or more PEFR performed either before or after treatment. Only 61 (50%) of the visits had a documented clinical re-evaluation prior to disposition. CONCLUSIONS: Despite their documented role in asthma treatment algorithms, PEFR was performed infrequently and clinical re-evaluation was documented in only half of cases. Recommended algorithms for asthma management were not commonly followed in this academic ED.
