Better health while you wait: a controlled trial of a computer-based intervention for screening and health promotion in the emergency department.

STUDY OBJECTIVE: We evaluate a computer-based intervention for screening and health promotion in the emergency department and determine its effect on patient recall of health advice. METHODS: This controlled clinical trial, with alternating assignment of patients to a computer intervention (prevention group) or usual care, was conducted in a university hospital ED. The study group consisted of 542 adult patients with nonurgent conditions. The study intervention was a self-administered computer survey generating individualized health information. Outcome measures were (1) patient willingness to take a computerized health risk assessment, (2) disclosure of behavioral risk factors, (3) requests for health information, and (4) remembered health advice. RESULTS: Eighty-nine percent (470/542) of eligible patients participated. Ninety percent were black. Eighty-five percent (210/248) of patients in the prevention group disclosed 1 or more major behavioral risk factors including current smoking (79/248; 32%), untreated hypertension (28/248; 13%), problem drinking (46/248; 19%), use of street drugs (33/248; 13%), major depression (87/248; 35%), unsafe sexual behavior (84/248; 33%), and several other injury-prone behaviors. Ninety-five percent of patients in the prevention group requested health information. On follow-up at 1 week, 62% (133/216) of the prevention group patients compared with 27% (48/180) of the control subjects remembered receiving advice on what they could do to improve their health (relative risk 2.3, 95% confidence interval 1.77 to 3.01). CONCLUSION: Using a self-administered computer-based health risk assessment, the majority of patients in our urban ED disclosed important health risks and requested information. They were more likely than a control group to remember receiving advice on what they could do to improve their health. Computer methodology may enable physicians to use patient waiting time for health promotion and to target at-risk patients for specific interventions.

Triage and initial evaluation of the oral facial emergency.

Essentially, emergency medicine encompasses the efficient application of limited resources to provide timely care to patients in health crisis. The appropriate triage, management, and disposition of patients with orofacial complaints requires systematic evaluation with attention to the ABCs. The first priority is to secure the airway. Once such a patient has been stabilized, a thorough examination, with documentation of the oropharyngeal and facial examination, should be conducted. Unfortunately, many conditions seen initially in the ED through patient self-referral ultimately require specialist care. Therefore, emergency physicians must temporarily provide pain relief and begin initial treatment of traumatic, infectious, or inflammatory conditions that await more definitive intervention. The emergency physician should consider it his or her role to exclude life threats, prevent complications, provide patient comfort, and ensure adequate and timely follow-up care.

Fatal vascular catastrophe in Ehlers-Danlos syndrome: a case report and review.

The Ehlers-Danlos syndrome (EDS) is a group of hereditary connective tissue disorders that are characterized by abnormalities of the skin, joints, and a diversity of other phenotypic manifestations. An awareness of the disease is vital for optimal outcome in this rare group of patients who may present with a variety of life-threatening illnesses. Ehlers-Danlos type IV has been associated with vascular catastrophes, perforated viscous, ruptured uterus, and pneumothorax (1-4). We present a case of aneurysmal formation and spontaneous rupture of the great vessels in a 15-year-old male with EDS type IV, who remained undiagnosed until the time of autopsy.

Utility of laboratory studies in the emergency department patient with a new-onset seizure.

Extensive laboratory testing is often performed in the emergency department evaluation of the new-onset seizure patient. To determine the utility of such testing, a prospective study of patients with a new-onset seizure presenting to the ED of an inner-city, university-affiliated teaching hospital was done. One hundred thirty-six patients were entered into the study between October 1984 and January 1988. All patients had uniform data collection performed. Pertinent historical information and physical examination findings were recorded on a standardized form before laboratory abnormality was a sole or contributory cause of the seizure disorder. These included four patients with hypoglycemia, four with hyperglycemia, two with hypocalcemia, and one with hypomagnesemia. Only two cases (hypoglycemia) were not suspected on the basis of findings on the history or physical examination. In ED patients, the incidence of a new-onset seizure due to a correctable metabolic disturbance is low. We conclude that, with the exception of the serum glucose, the extensive ED laboratory workup often done for the evaluation of a new-onset seizure is unnecessary. Further test ordering should be directed by the medical history and physical examination.

The mental status evaluation. Application in the emergency department.

The mental status evaluation is a useful test in the emergency department. The major purposes of the examination are to determine the presence of neuropsychiatric illness and to determine whether this illness is functional or organic. The most accepted evaluation of mental status is the formal mental status evaluation. This extensive test is rarely necessary in the emergency department; rather a short test of cognitive function, such as the Cognitive Capacity Screening Examination or Mini-Mental Status Examination, may be more appropriate. With frequent repetition in use and the concomitant development of clear standards for interpretation of the examination used, the emergency physician will become more comfortable with bedside mental status testing.

The red eye.

The patient with a red eye constitutes a very common clinical problem encountered in the Emergency Department setting. Conjunctivitis, the most common cause of the red eye, generally is not associated with disturbance of vision or associated ocular pain. If either of these symptoms is present, a more serious disorder must be suspected. Treatment of infectious conjunctivitis is guided by interpretation of a Gram's stain and subsequent culture of any exudate present. Initial treatment of most cases includes use of topical antibiotic and local comfort measures. Complications of infectious conjunctivitis include more invasive disease such as keratitis or abscess formation, with potential corneal perforation and destruction. All patients should be referred for ophthalmologic followup, both to assess adequacy of treatment and to treat unexpected complications. Remember that allergic conjunctivitis is a common condition that responds to antihistamine decongestant medications given orally or topically. Occasionally these conditions are caused by self-prescribed use of ocular medication, and discontinuation of all eye medication is required. Corticosteroid eye drops are rarely indicated and should be used only at the direction of an ophthalmologist. When the diagnosis is uncertain, treatment is best withheld, as "shotgun" therapy is seldom beneficial.

Efficacy of a "standard" seizure workup in the emergency department.

In many institutions it is the "standard of care" to obtain serum chemistries and anticonvulsant levels as part of the emergency department evaluation of seizure patients. To determine the efficacy of such a workup in the ED, 163 seizure patients presenting to an inner-city teaching hospital were studied in a standardized, prospective manner. After the clinical examination all patients had CBC, serum electrolyte, BUN, creatinine, glucose, calcium, magnesium, and if indicated, anticonvulsant drug level determinations performed. Any patient presenting with a first-time seizure (in patients greater than 6 years old), recent head trauma, focal neurologic deficit, or focal seizure activity had cranial computerized tomography (CCT). After obtaining historical and physical examination and before receiving laboratory results, as many as five likely etiologies were listed and assigned probability ratings. After review of the laboratory data (and CCT scan, if obtained), final etiologies again were listed and assigned percentages of likelihood. Significant abnormalities (ie, those that changed diagnosis, management, or disposition) were found in 104 patients; 96 had subtherapeutic anticonvulsant levels, five had abnormal CCT scans, two had hypoglycemia, and one had hyperglycemia as the cause of seizure. The clinical examination successfully predicted those abnormalities in all but two cases (one each of hyperglycemia and subdural hematoma). We contend tha routine serum chemistries in patients presenting to the ED are of extremely low yield, and that the clinical examination can predict accurately the need to obtain these studies. CCT scanning is useful in selected patients, and was found to be abnormal in five of 19 (25%) patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Plaster splints: techniques and indications.

Various plaster splints can be used in the management of many acute musculoskeletal injuries seen in the emergency setting. These include gutter splints of thumb, radial and ulnar types; volar forearm, sugar-tong and posterior elbow splints, and knee, short leg and stirrup splints. When properly made, these devices afford symptomatic relief, mechanical support and sometimes even definitive therapy for fractures and soft tissue injuries of the extremities.
