Establishing a case-finding and referral system for at-risk older individuals in the emergency department setting: the SIGNET model.

Older emergency department (ED) patients have complex medical, social, and physical problems. We established a program at four ED sites to improve case finding of at-risk older adults and provide comprehensive assessment in the ED setting with formal linkage to community agencies. The objectives of the program are to (1) improve case finding of at-risk older ED patients, (2) improve care planning and referral for those returning home, and (3) create a coordinated network of existing medical and community services. The four sites are a 1,000-bed teaching center, a 700-bed county teaching hospital, a 400-bed community hospital, and a health maintenance organization (HMO) ED site. Ten community agencies also participated in the study: four agencies associated with the hospital/HMO sites, two nonprofit private agencies, and four public agencies. Case finding is done using a simple screening assessment completed by the primary or triage nurse. A geriatric clinical nurse specialist (GCNS) further assesses those considered at risk. Patients with unmet medical, social, or health needs are referred to their primary physicians or to outpatient geriatric evaluation and management centers and to community agencies. After 18 months, the program has been successfully implemented at all four sites. Primary nurses screened over 70% (n = 28,437) of all older ED patients, GCNSs conducted 3,757 comprehensive assessments, participating agency referrals increased sixfold, and few patients refused the GCNS assessment or subsequent referral services. Thus, case finding and community linkage programs for at-risk older adults are feasible in the ED setting.

Improved outcome after early fixation of acetabular fractures.

This study was done in order to evaluate the effect of the timing of fixation for acetabular and pelvic ring fractures on patient outcome. Demographic, clinical and outcome data for 5821 trauma patients admitted from January 1993 through January 1996 were retrospectively reviewed. Pelvic fractures were classified according to Young and Burgess. Patients who had fixation within 24 h of admission were compared with those who had later operation. Main outcome measures were Multiple Organ Dysfunction Score according to Moore, hospital and intensive care unit length of stay and discharge disposition. Out of 416 patients with pelvic fractures, one hundred patients had fracture fixation [90 open reduction and internal fixation, 10 external fixation]. There were 59 acetabular fractures and 41 pelvic ring fractures. The overall mortality was 4%. Early fixation of acetabular fractures was associated with lower MODS (p < 0.006) and decreased total length of stay (p < 0.026). Length of hospital stay was also less with early fixation of pelvic ring fractures (p < 0.04). Functional outcome was improved in early fixation of acetabular fractures with a greater proportion of patients being discharged home rather than to rehabilitation or skilled care (p = 0.05). Patients who underwent early repair of acetabular and pelvic ring fractures had a shorter length of hospital stay compared to those with late fixation. Patients with early repair of acetabular fractures had significantly less organ dysfunction and exhibited improved functional outcome.

Utility of clinical characteristics in identifying depression in geriatric ED patients.

We will determine if clinical characteristics can be useful in identifying depression in geriatric Emergency Department (ED) patients. We have provided a cross-sectional observational study of geriatric patients presenting to an urban university-affiliated public hospital. A brief self-rated depression scale (SRDS) was used to identify depression. Clinical characteristics, examined retrospectively, included chief complaint, chronic illnesses, mode and time of arrival and discharge disposition. Relative prevalence of depression was calculated for these clinical characteristics. 70 (27%; 95% CI, 22% to 32%) of 259 patients were found to be depressed by the SRDS. Patients with nonspecific chief complaints were more commonly depressed than patients with system-specific chief complaints, but not significantly (relative prevalence 1.6; 95% CI, 1.0 to 2.4; p = 0.19). The relative prevalence of depression also did not vary significantly when analyzed by specific chronic illness (P = 0.42) except cardiac disease (1.6; 95% CI, 1.1 to 2.4), PM or night arrival (1.3; 95% CI, 0.8 to 2.3; p = 0.17), ambulance use (1.1; 95% CI, 0.7 to 1.7; p = 0.88), or need for medical admission (1.0; 95% CI, 0.7 to 1.5; p = 0.97). Depression is common in geriatric ED patients. Clinical characteristics fail to identify elderly ED patients who are likely to be depressed. Use of a brief SRDS can aid in recognition of depression in this group.

Academic emergency medicine staffing nonacademic emergency department sites: a national survey.

UNLABELLED: Changing health care markets have threatened academic health centers and their traditional focus on teaching and research. OBJECTIVES: To determine the number of academic emergency medicine departments (AEMDs) that staff additional non-academic ED sites and to determine whether clinical reimbursement monies from those ED sites are used for academic purposes. METHODS: A two-part survey of all 119 academic EM programs listed in the 1997-1998 Graduate Medical Education Directory was conducted. Questionnaires were addressed to each AEMD chair. AEMDs and ED sites were characterized. Hiring difficulties, EM faculty academic productivity, and use of ED site reimbursement monies for academic activities were assessed. RESULTS: Ninety-nine of 119 (83%) AEMDs responded. Twenty-three (23%) AEMDs staffed 28 added ED sites. These sites tended to be urban (65%), with moderate volumes (25,000-35,000 patients/year), and had an equal or better reimbursement rate than the AEMD (89%). ED sites were commonly staffed by academic EM faculty (79%) and EM residents (29%). Ninety-six percent of the AEMDs had hired additional faculty; hiring new faculty was considered easy. Academic productivity at AEMDs with added ED sites was reported as unchanged. Reimbursement monies from these ED sites were commonly used for faculty salary support, faculty development, and EM research and residency activities. CONCLUSIONS: Academic EM departments are often affiliated with nonacademic ED sites. These additional sites are commonly staffed by academic EM faculty and EM residents. Academic productivity does not appear to decrease when additional ED sites are added. Reimbursement monies from these ED sites commonly supports academic activities.

Usefulness of the total iron binding capacity in the evaluation and treatment of acute iron overdose.

The ingestion of iron-containing products is a potential toxicologic emergency. The total iron binding capacity (TIBC) has been used widely as a predictor of end-organ toxicity and a guide to the need for deferoxamine therapy. When the TIBC is greater than the serum iron concentration (SIC), it is held that no free iron is present to cause toxicity. The TIBC fails as a marker of toxicity for several reasons. First, the laboratory methods used to measure TIBC are inaccurate in the setting of iron overload. Second, the presence of deferoxamine, the antidote for iron poisoning, has been shown to make the TIBC measurement inaccurate. Third, TIBC measurements have been shown to be variable. Finally, studies and case reports demonstrate toxicity even when the TIBC is greater than the SIC. These shortcomings of the TIBC invalidate it as a predictor of toxicity in iron poisoning.

Out-of-hospital cervical spine clearance: agreement between emergency medical technicians and emergency physicians.

OBJECTIVE: Determine the level of agreement between emergency medical technicians (EMTs) and emergency physicians (EPs) when applying an existing emergency medical services/fire department protocol for out-of-hospital clinical cervical spine injury (CSI) clearance in blunt trauma patients. METHODS: Prospective observational study of consecutive blunt trauma patients transported by emergency medical services/fire department during a 3-month study period. The setting was an urban Level I trauma center. Measurement of interrater agreement (kappa) was determined. RESULTS: Mean age of the 190 patients was 34+/-19 years (range, 6 -98 years). Fifty-nine percent of the patients were male. One hundred forty-six patients (77%) were immobilized by EMTs; 17 of these patients were clinically cleared by EPs. Forty-four patients (23%) were clinically cleared by EMTs and presented without CSI precautions; of these, 61% (27 of 44) were immobilized by EPs and 57% (25 of 44) had cervical spine radiographs obtained. Overall, 141 patients (74%) required radiographic clearance. CSI were detected in five patients (2.6%); all five were immobilized in the out-of-hospital setting. Overall disagreement between EMTs and EPs regarding out-of-hospital CSI clearance occurred in 44 patients (23%) (kappa=0.29; 95% confidence interval, 0.15-0.43; p < 0.01). CONCLUSION: Significant disagreement in clinical CSI clearance exists between EMTs and EPs. Further research and education is recommended before widespread implementation of this practice.

Effectiveness of a 2-specialty, 2-tiered triage and trauma team activation protocol.

STUDY OBJECTIVE: To determine the effectiveness, safety, and resource allocation of a 2-specialty, 2-tiered triage and trauma team activation protocol. METHODS: We conducted a 6-month retrospective analysis of a 2-specialty, 2-tiered trauma team activation system at an urban Level I trauma center. Based on prehospital data, patients with a high likelihood of serious injury were assigned to triage category 1 and patients with a low likelihood of serious injury were assigned to category 2. Category 1 patients were immediately evaluated by both emergency medicine and trauma services. Category 2 patients were evaluated initially by emergency medicine staff with a mandatory trauma service consultation. Main outcomes measured included mortality, need for emergency procedures, need for emergency surgery, complications, and discharge disposition. Potential physician-hours saved were calculated for category 2 cases. RESULTS: Five hundred sixty-one patients were assigned a triage classification (272 to category 1 and 289 to category 2). Category 1 patients had a higher mortality rate (95% confidence interval [CI] for difference of 15.9%, 11.1% to 20.7%, P < .0001), need for emergency surgery (10.7% versus 1.4%, 95% CI for difference of 9.3%, 5.2% to 13.4%; P < .0001), need for emergency procedures (89% of total procedures, 95% CI 83% to 95%; P < .0001), and discharges to rehabilitation facilities (95% CI for difference of 15.1%, 9.3% to 21.0%; P < .0001). The 2-tiered response system saved an estimated 578 physician-hours of time for the trauma service over the study period. CONCLUSION: This evaluation tool effectively predicts likelihood of serious injury, mortality, need for emergency surgery, and need for rehabilitation. Patients with a low likelihood of serious injury may be initially evaluated by the emergency medicine service effectively and safely, thus allowing more efficient use of surgical personnel.

Recognition of depression in geriatric ED patients by emergency physicians.

STUDY OBJECTIVE: To prospectively evaluate identification of geriatric depression by emergency physicians and to assess the utility of a self-rated depression scale to improve case-finding in geriatric patients presenting to the ED. METHODS: We conducted an observational survey of geriatric ED patients who presented to an urban, university-affiliated public hospital. A brief self-rated depression scale was administered to 101 patients aged 65 years or older. Emergency physicians, blinded to depression scale scores, prospectively rated the likelihood of depression in these patients. Our main outcome measures were prevalence of depression (in accordance with a predetermined cutoff score for detecting depression) and the emergency physicians' clinical recognition of depression. RESULTS: Thirty patients (30%; 95% confidence interval [CI], 21% to 39%) met the predetermined criteria for depression. Age, sex, race, and education were not significantly different between depressed and nondepressed patients. Patients who categorized their health as good were less likely to be depressed than those who considered their health poor or fair (18% versus 37%; 95% CI for difference of 19%, 10% to 35%). Recognition of depression by emergency physicians was poor, with a sensitivity of 27% (95% CI; 12% to 46%), specificity of 75% (95% CI, 63% to 84%), and positive predictive value of 32% (95% CI, 27% to 41%). Only 13% (95% CI, 4% to 31%) of depressed patients were referred for further mental health evaluation. CONCLUSION: Depression is common in older ED patients but often goes unrecognized by emergency physicians. Use of a brief depression scale can improve case-finding in this age group, leading to appropriate referral for further management.

Depression in geriatric ED patients: prevalence and recognition.

STUDY OBJECTIVE: To determine the prevalence of depression in geriatric ED patients and to assess recognition of geriatric depression by emergency physicians. METHODS: We conducted an observational survey of geriatric patients who presented to an urban, university-affiliated public hospital ED. A convenience sample of 259 patients aged 65 years or older were administered a brief, self-rated depression scale. Main outcome measures were prevalence of depression (using a predetermined cutoff score for detecting depression) and recognition of depression by the treating emergency physician, assessed by chart review. RESULTS: Seventy subjects (27%; 95% confidence interval [CI], 22% to 32%) were rated as depressed. Depressed and nondepressed patients were not significantly different with regard to age, sex, race, or education. Forty-seven percent of nursing home residents were depressed, compared with 24% of those living independently (95% CI for difference of 23%, 6% to 41%). Patients who described their health as poor were also more likely to be depressed (33 of 65, 51%) than patients who reported their health to be good or fair (37 of 194, 19%) (95% CI for difference of 32%, 18% to 45%). Emergency physicians failed to recognize depression in all the patients found to be depressed on this scale (95% CI, 0 to 5%). CONCLUSION: The prevalence of unrecognized depression in the geriatric ED patients we studied was high, especially in those who reported their health as poor. Use of a brief depression scale can aid recognition of depression in older patients, leading to appropriate referral and treatment.

Thoracolumbar spine fractures: clinical presentation and the effect of altered sensorium and major injury.

A retrospective review of 145 patients with thoracic or lumbar spine fractures from blunt trauma was conducted to identify the clinical presentation of these patients. The presence of back pain or tenderness (BPT), neurologic injury, altered sensorium from head injury or alcohol intoxication, and concomitant major injury were determined. Any delayed or missed diagnoses were analyzed. One hundred eighteen (81%) patients complained of BPT on their initial presentation. The presence of BPT was significantly higher in those patients without an altered sensorium or other major injury. Of the 27 (19%) patients with a negative finding of BPT, all (100%) had an altered sensorium, concomitant major injury, or neurologic deficit. There were no asymptomatic thoracic or lumbar spine fractures in neurologically intact patients with clear sensoriums and no concomitant major injuries. These patients do not need routine thoracolumbar radiography.

Ligamentous injuries of the wrist.

Wrist injuries occur commonly. Significant wrist injuries such as perilunate dislocation and scapholunate dissociation may occur without carpal bone fracture. The emergency physician can recognize these ligamentous wrist injuries by noting abnormalities of the shapes, joint spaces, and alignments of the carpal bones. Early diagnosis allows for prompt referral and optimal outcome.
