A survey about management of febrile children without source by primary care physicians

BACKGROUND: The management of young children with fever without source is controversial, and differences between physician specialties have been noted previously. The emergence of penicillin-resistant Streptococcus pneumoniae, the sharp decline in invasive Haemophilus influenzae infections in immunized populations and publication of practice guidelines have potentially altered physician practices. OBJECTIVE: To determine the present practice preferences of pediatricians, family medicine physicians (FP) and emergency medicine physicians (EP). METHODS: We mailed a checklist survey to 1600 randomly selected pediatricians, family medicine practitioners (FP) and emergency medicine physicians (EP) in the United States and replicated the methodology of a 1991/1992 survey. Physicians were asked about their evaluation and management of children of various ages (3 weeks, 7 weeks, 4 months and 16 months) with fever without source. RESULTS: Most primary care physicians would admit the 3- and 7-week-old infants. For the 4-month-old infant 59% of EP, 45% of pediatricians and 28% of FP would give empiric antibiotic(s) as an outpatient (P=0.005 for FP compared with pediatricians and P=0.02 for EP compared with pediatricians). The majority of physicians would manage the 16-month-old child as an outpatient without antibiotic therapy. Ceftriaxone was the preferred antibiotic for outpatient empiric therapy. There was a 3-fold increase (28% vs. 9%) for pediatricians in the use of empiric outpatient antibiotics for the 7-week-old infant in the present survey compared with the 1991/1992 survey. CONCLUSIONS: Physicians in the United States generally agree in their management of the young febrile infant, but with increasing patient age there is considerable variation. FP were the least aggressive in their evaluation and EP were the most aggressive.     

Clinicopathologic characteristics of replication error-positive gastric carcinoma

OBJECTIVES: To determine the incidence of skull fracture (SF) and intracranial injury (ICA) among children younger than 2 years evaluated in a pediatric emergency department for head trauma; whether historical features and/or physical findings are predictive of injury type; and whether clinical criteria could allow a selective approach to radiographic imaging. DESIGN: Retrospective medical record review. SETTING: Tertiary pediatric emergency department. PATIENTS: Case series of 278 children aged younger than 24 months evaluated for head injury. MAIN OUTCOME MEASURES: Presence of SF and/or ICA. RESULTS: Diagnoses at discharge included 227 minor head injuries, 39 isolated SF, 9 ICA with SF, and 3 isolated ICA. Children younger than 12 months had the highest incidence of SF/ICA (29%) vs 4% for children aged 13 to 24 months (P<.001). Seven percent of complications from SF/ICA resulted from falls 3 ft (0.9 m) or less [corrected]. Incidence of behavioral change, loss of consciousness, emesis, and seizures did not differ significantly between those with minor head injuries and those with SF/ICA. Scalp abnormalities were more common in children with SF/ICA (P<.001). Sixty-two percent of children with isolated SF and 58% of children with ICA had no history of loss of consciousness, emesis, seizure, or behavioral change. Ninety-two percent of children with isolated SF and 75% of children with ICA had normal levels of consciousness and nonfocal neurologic examinations at diagnosis. Among children who fell 3 ft or less (0.9 m) [corrected] and had no loss of consciousness, emesis, seizure, behavioral change, or scalp abnormality, none of 31 (95% confidence interval [CI], 0-0.10) children younger than 24 months and none of 20 (95% CI, 0-0.15) children younger than 12 months had SF/ICA. CONCLUSIONS: Both SF and ICA are common in children younger than 2 years evaluated for head trauma. Children younger than 12 months are at highest risk. Injuries resulted from relatively minor falls and occurred in alert, neurologically normal children. Clinical signs and symptoms were insensitive predictors of SF/ICA; however, a grouping of features (fall < or = 3 ft [0.9 m], no history of neurologic symptoms, and normal scalp physical examination results) identified a subset of children at low risk for complications.     

Firearm injury prevention counseling by pediatricians and family physicians. Practices and beliefs

OBJECTIVES: To ascertain and compare beliefs, attitudes, and counseling practices of primary care physicians of children and adolescents regarding firearm injury prevention counseling. DESIGN: Cross-sectional survey. SETTING: State of Washington. SUBJECTS: All active members of the state chapters of the American Academy of Pediatrics and American Academy of Family Physicians. A total of 979 pediatricians and family physicians (53%) responded to the survey after two mailings. MAIN OUTCOME MEASURES: Attitudes, beliefs, and current practices with regard to firearm safety counseling among families of child and adolescent patients. RESULTS: Only 25% of pediatricians and 12% of family physicians currently counsel more than 5% of their patients. Pediatricians were more likely than family physicians (70% vs 46%, P < .001, chi 2 test) to believe that physicians have a responsibility to counsel families about firearm safety. Pediatricians recommended removing guns from the home more frequently than family physicians (32% vs 19%, P < .001, chi 2 test), but most physicians of both specialties perceived that parents are rarely receptive to this advice. However, 97% of physicians from both specialties agreed that firearms should be stored locked separately from ammunition, and a substantial majority believed that parents would be receptive to this advice. Compared with physicians who owned guns (32%), non-owners were 15 times more likely (odds ratio, 15; 95% confidence interval, 10 to 23) to agree that families with children should not keep firearms in the home. CONCLUSIONS: Few primary care physicians who see children and adolescents currently counsel families about firearm safety, although many agree that they have such a responsibility. At least half of these physicians would potentially benefit from an intervention to improve their knowledge of and counseling skills on this topic.     

Identification of ethanol-intoxicated patients with minor head trauma requiring computed tomography scans

OBJECTIVE: To determine whether clinical parameters and neurologic scores can be used to guide the decision to obtain computed tomography (CT) head scans for ethanol- intoxicated patients with presumed-minor head injuries. METHODS: In a prospective cohort analysis, 107 consecutive adult patients who presented to a county emergency department (ED) with serum ethanol levels >80 mg/dL and minor head trauma were studied. Commonly used clinical variables were determined for each patient. Each patient also underwent an abbreviated neurologic scoring examination and a Glasgow coma scale (GCS) score evaluation at the time of presentation and one hour later, after which a cranial CT scan was done. For purposes of analysis, patients with and patients without intracerebral injuries visible on CT scans of the head were compared. RESULTS: Nine of 107 patients (8.4%; 95% confidence interval [CI] = 3.9-15.4%) had CT scans that were positive for intracerebral injury. Two patients (1.9%; 95% CI = 0.2-6.6%) needed craniotomy. Five patients had hemotympanum and two patients had bilateral periorbital ecchymosis, but CT scans were negative for intracerebral injury in these patients. There was no statistically significant difference between the patients with and without CT scan abnormalities, based on the clinical variables, the GCS scores, or the abbreviated neurologic scoring examinations at presentation or at one hour. CONCLUSION: The prevalence of intracerebral injury in CT scans of ethanol-intoxicated patients with minor head injuries was 8.4%. Commonly used clinical parameters and neurologic scores at presentation and one hour later were unable to predict which patients would have intracerebral injuries and evidenced by CT scans. Our low (1.9%) neurosurgical intervention rate supports the need to develop a selective approach to CT scanning in this population.     

CT of head trauma

The advent of CT in the early 1970s revolutionized the diagnosis and management of head trauma patients. CT remains to be the imaging modality of choice in the evaluation of patients with acute head trauma. High resolution CT is excellent for evaluating facial and skull fractures. Neurosurgically significant lesions such as epidural hematomas, subdural hematomas, or depressed skull fractures are already detected by CT. The early detection of extra-axial hematomas made possible by the increased availability of CT, results in early surgical interventions with marked improvement in morbidity and mortality in head trauma patients.     

Mild head trauma

Patients with mild traumatic brain injury constitute the overwhelming majority of head-injured patients seen in the emergency department. The indications for radiologic imaging in these patients are still undergoing study and revision. The Glasgow Coma Scale is a widely used triage score for head injury, but is less useful at identifying which patients with mild head injuries have intracranial pathology. There have been several retrospective studies and a few prospective studies examining the indications for imaging in mild to moderate head trauma. They all show that it is not easy to predict which patients will have CT abnormalities, and that some of these patients do go on to require neurosurgery. No set of clinical predictors have yet been put together that is capable of identifying all patients who are safe to be discharged without a CT scan. Pharmacologic therapy to help reduce axonal damage after head trauma and thus minimize the postconcussive sequelae of mild traumatic brain injury remains a challenge for physicians and neurobiologists into the next century.     

Quantitative changes in the ultrastructure of myocardial cells in Japanese quail during hypergravity, hypodynamia and space flight

To assess the consultation patterns of pediatric emergency physicians in the management of injured children and to describe the spectrum of pediatric trauma, we retrospectively reviewed 601 patients treated in the emergency department for injuries during four one-week periods at a designated level I regional pediatric trauma center (50,000 patients/year) with a pediatric emergency medicine fellowship. The majority (94%) of pediatric trauma was minor; only 2% of children had injuries severe enough to require direct transfer to the operating room. The highest volume of patients, the greatest number of consultations, and the majority of admissions to the operating room occurred between 4 PM and midnight. No patients went to the operating room on the night shift. Musculoskeletal injuries constituted the predominant category of pediatric trauma, and lacerations were the most common specific injury. One half of all procedures involved laceration repair, and one third involved splinting or casting. Four hundred ten patients (68%) were managed by physicians in the emergency department without consultation. The orthopedic service performed one half of all consultations and admitted the largest number of patients; the majority of patients taken directly to the operating room had musculoskeletal injuries.(ABSTRACT TRUNCATED AT 250 WORDS)     

Whole body spiral CT in primary diagnosis of patients with multiple trauma in emergency situations

PURPOSE: The aim of this study was to evaluate the role of a fast whole body helical CT scanner for primary diagnosis in trauma patients. METHODS: 27 severely injured patients (9 women, 18 men; mean age 43 years) were first examined with a helical CT scanner allowing for digital radiograms up to a length of 1024 mm and continuous helical scans of up to 70 seconds (slice thickness 3 to 10 mm, pitch factor up to 2). The primary CT diagnosis was verified either by x-ray after the CT examination or during the subsequent days, by abdominal ultrasound, by additional CT scans in the following days, and by clinical follow-up. RESULTS: CT showed all clinically relevant injuries of the head, spine, chest, abdomen and pelvis. The diagnosis and classification of vertebral fractures was performed immediately. 4% of the fractures of the extremities and the ribs were not seen primarily. 6% of the injuries were outside the CT scan field. CONCLUSION: Helical CT is a reliable and fast method to obtain vital information and to improve management planning in severely injured patients. It reduces the number of conventional x-ray examinations. In certain cases, additional x-rays of extremity fractures may be required.     

Evaluation of head injury in a pediatric emergency department: pretrauma and posttrauma system

OBJECTIVE: To determine if trauma center protocols affect the number of tests and consultations performed and the length of time spent in the emergency department or hospital. DESIGN: A retrospective review and comparison of treatment for children with isolated head injury admitted to the emergency department before trauma center designation (group 1, 1985), and 5 years after implementation of trauma center protocols (group 2, 1991). SETTING: Urban children's hospital, level I trauma center. RESULTS: One hundred sixty-five children met the enrollment criteria in 1985 and 162 met the criteria in 1991. Falls were the predominant mechanism of injury (55%) for both years. For patients with moderate injury (Glasgow Coma Scale score, 9-12) or severe injury (Glasgow Coma Scale score, <9), there was no difference in radiographic or laboratory evaluation. For patients with minimal head injury (Glasgow Coma Scale score, 15, no loss of consciousness, amnesia, seizure, focal neurologic findings, or persistent symptoms) and minor head injury (Glasgow Coma Scale score, >12, and loss of consciousness or amnesia), more radiologic and laboratory studies were done in 1991 that showed no clinically significant abnormalities. Patients with minimal head injury in group 2 were 14 times more likely to have cranial computed tomographic scans performed (95% confidence interval [CI], 3.4-67); 11 times more likely to have cervical spine radiographs (95% CI, 2.2-76.6); and 23 times more likely to have hepatic enzymes obtained (95% CI, 3-491). These differences persisted when analyzed by both the age of the patient and mechanism of injury. CONCLUSIONS: Application of trauma system protocols to isolated head injury patient evaluation results in increased use of laboratory and radiologic services. These practices have the potential to increase the cost of medical care without significantly improving outcome.     

Future trends for experimental surgery in laboratory animal science

It has been suggested that all children with skull fractures require urgent CT scanning to exclude intracranial injury. Adhering to such a policy could both tax limited scanning facilities and result in unnecessary exposure to radiation. The aim of this study is to assess the level of consciousness in determining the need for urgent CT scanning, and the possible role of the mechanism of injury as a secondary risk factor. We identified 140 children admitted during a 7-year period with a skull fracture after falling outside the home. Thirteen children had a diminished level of consciousness. Scans were performed in nine, and seven of the scans revealed significant intracranial injuries. By comparison, all 127 children with a normal level of consciousness recovered fully. Scanning was performed in only eight of them; seven scans were normal and one revealed a small subarachnoid heamorrhage which did not require active treatment. In addition, all 13 children with a diminished level of consciousness had sustained their injuries by falling from greater than their own standing height. By comparison, none of the children who had sustained their skull fractures by tripping up had a diminished level of consciousness or a significant intracranial injury. We conclude that all children with a diminished level of consciousness need to undergo an urgent CT scan. Children with skull fractures and a normal conscious level may be managed initially by neuroobservations and the clinician may be further reassured if the child's injury resulted from tripping up.     

Computed tomography scanning and delirium in elder patients

OBJECTIVE: 1) To examine the ordering of head CT scans in elder patients with delirium and cognitive impairment; and 2) to report CT scan findings associated with these conditions. METHODS: This was a 2-part study. Part 1 was a prospective, observational study of 560 adults > 70 years of age evaluated at 3 separate EDs using a 200-hour stratified sampling process at each ED. During Part 1, the frequencies of specific findings (i.e., delirium, impaired consciousness, and impaired cognition) and CT scan rates for these groups were determined. Part 2 was a retrospective analysis of CT scan reports and medical records (n = 279) for patients > 70 years of age in the prospective sample (n = 79) and from a sample (n = 200) of CT scans obtained at a fourth ED. Part 2 examined clinical findings detected in the ED to determine those factors that were associated with acute findings on CT scan. RESULTS: Part 1: There were 333 (59.4%) patients prospectively classified as having impaired cognition, impaired consciousness, or delirium; 79 (23.7%) of these patients had a head CT scan. Of these 3 groups, delirious patients were more frequently scanned (p < 0.001). Part 2: Of 279 CT scans, 42 (15.0%) were positive for an acute condition (hemorrhage, hematoma, space-occupying lesion, infarct). Of 42 positive scans, 40 (95.1%) were found in the 102 (36.6%) patients with either impaired consciousness or a new focal neurologic finding detected in the ED. CONCLUSIONS: Considerable variability in ED CT scan ordering exists for elder patients with neurologic findings. Impaired consciousness and/or new focal neurologic signs are associated with acute findings on CT scan in elder patients. Acute CT abnormalities are uncommon in elder ED patients with other neurologic findings. Additional prospective evaluation is warranted prior to guideline development for CT scans in this patient population.     

Middle cerebral artery dissection

A 12-year-old girl had minor head trauma, with resultant mild headache, one day prior to onset of an apparently generalized tonic clonic seizure, right hemiparesis and dysphasia. A cranial CT scan showed evidence of a left middle cerebral artery infarct. Despite ventilation, fluid restriction, mannitol, thiopental infusion and intracranial pressure monitoring she deteriorated and died. Autopsy demonstrated dissection of the left middle cerebral artery with an intact internal carotid artery and no evidence of vasculitis. Middle cerebral artery dissection in children is very rare. Most reported cases are diagnosed at autopsy. The pathogenesis of cerebral artery dissection may include preceding minor head trauma or exertion and this should be sought for in the history.     

Moderate head injuries in children as compared to other age groups, including the cases who had talked and deteriorated

Patients defined as having a moderate head injury on the basis of Glasgow Coma Scale scores within the ranges of 9 to 13 after acute nonsurgical procedures were selected. Almost 1600 cases were hospitalized in the Neurosurgery Department. The cases were admitted through the Emergency Unit of Gaz University Medical School, Ankara, Turkey during the period between 1979 and 1992. The group studied consisted of 231 selected patients assessed separately in paediatric, adult and elderly age groups. Possible risk factors such as: GCS score, anisocoria, unilateral or bilateral fixed pupils, impaired oculocephalic reflexes, presence of multiple systemic injuries, aetiology of head trauma, presence of linear or depressed skull fractures, space occupying mass on CT or operation was also assessed. Subarachnoid haemorrhage turned out to be the only independent significant risk factor in predicting mortality. The data about the patients who have "talked and deteriorated" were also reported so as to assisst physicians charged with the care of trauma victims.     

Importance of bone attenuation in brain SPECT quantification

The purpose of this study was to determine the effects of nonuniform attenuation on relative quantification in brain SPECT and to compare the ability of the Chang and Sorenson uniform attenuation corrections (UACs) to achieve volumetric relative quantification. METHODS: Three head phantoms (dry human skull, Rando and Radiology Support Devices (RSD) phantoms) were compared with a human head using a gamma camera transmission CT (gammaTCT) SPECT system and x-ray CT. Subsequently, the RSD phantom's brain reservoir was filled with a uniform water solution of 99mTc, and SPECT and gammaTCT data were acquired using fanbeam collimation. The attenuating effects of bone, scalp and head-holder in individual projections were determined by an analytical projection technique using the SPECT and gammaTCT reconstructions. The Chang UAC used brain and head contours that were segmented from the gammaTCT reconstruction to demarcate its attenuation map, whereas the Sorenson UAC fit slice-specific ellipses to the SPECT projection data. For each UAC, volumetric relative quantification was measured with varying attenuation coefficients (mus) of the attenuation map. RESULTS: Gamma camera transmission CT and x-ray CT scans showed that the dry skull and Rando phantoms suffered from a dried trabecular bone compartment. The RSD phantom most closely reproduced the attenuation coefficients of the human gammaTCT and x-ray CT scans. The analytical projections showed that the attenuating effects of bone, scalp and head-holder were nonuniform across the projections and accounted for 18%-37% of the total count loss. Volumetric relative quantification was best achieved with the Chang (zero iterations) attenuation correction using the head contour and mu = 0.075 cm(-1); however, cortical activity was found to be 10% higher than cerebellar activity. For all UACs, the optimal choices of mu were experimentally found to be lower than the recommended 0.12 cm(-1) for brain tissue. This result is theoretically supported here. CONCLUSION: The magnitude of errors resulting from uniform attenuation corrections can be greater than the magnitudes of regional cerebral blood flow deficits in patients with dementia, as compared with normal controls. This suggests that nonuniform attenuation correction in brain SPECT imaging must be applied to accurately estimate regional cerebral blood flow.     

Botulinum toxin injections in the internal anal sphincter for the treatment of chronic anal fissure: long-term results after two different dosage regimens

OBJECTIVE: To determine whether the recently published guidelines on neuroimaging in patients with new-onset seizures are applicable to children. METHODS: We carried out a retrospective analysis of 107 neurologically normal children (excluding children with simple febrile seizures) who had undergone neuroimaging when they presented to the emergency department with a possible "first seizure." RESULTS: Eight of the 107 children had nonepileptic events (gastroesophageal reflux, syncopal event, rigor). Of the remaining 99 children, 49 had provoked seizures (complicated febrile seizure, meningo-encephalitis, toxic or metabolic abnormalities), and 50 had unprovoked seizures. A total of 19 children had brain abnormalities identified on computed tomography (CT) scan; 7 received further investigation or intervention as a result of CT scan findings (2 with tumors, 3 with vascular anomalies, 1 with cysticercosis, and 1 with obstructive hydrocephalus). CT scan abnormalities requiring treatment or monitoring were more frequently seen in children with their first unprovoked seizure (P < .01) and in those children whose seizure onset had been focal or who had focal abnormalities identified on postictal neurologic examination (P < .04). CONCLUSION: In a child, a seizure in the setting of a fever rarely indicates the presence of an unexpected CT scan lesion requiring intervention.     

Critical review of the diagnostic protocol in patients with head injury

The results of a retrospective review of the conventional radiographs performed on head injury patients are reported. Skull radiography findings were compared with clinical symptoms and CT results, when CT was performed, to investigate the presence of intracranial lesions. The radiographs of 2,285 adult patients of both sexes were evaluated: skull fractures were observed in 21/2,285 patients (0.9%) only. CT was positive for an intracranial lesion in 18 of 21 patients (85.71%). Clinical symptoms were divided into three groups according to lesion severity and to neurologic impairment. 979 patients were asymptomatic and 1,306 were symptomatic: 1,114 patients were included in group I, their symptoms being nausea, vomit and loss of consciousness for less than ten minutes, 124 were included in group II (epistaxis and loss of consciousness for more than 10 minutes) and 68 were included in group III (coma and focal neurologic signs). All the patients in groups II and III and 30 patients in group I were submitted to CT--222 CT exams on the whole. Thirty-five patients in group III and 9 in group II had an intracranial lesion on CT, while CT findings were normal in all group-I patients. Thus, we conclude that the presence of a skull fracture is not always correlated with the presence of intracranial lesions. The latter are more likely to be correlated with clinical symptoms, especially coma and neurologic impairement. Therefore, the higher value is confirmed of the clinical examination than of conventional radiographs in head injury patients.     

99mTc-HMPAO SPECT of the brain in mild to moderate traumatic brain injury patients: compared with CT--a prospective study

Single photon emission computed tomography (SPECT) with Technetium-99m hexamethyl propylenamine oxime (Tc-99m-HMPAO) was used in 20 patients with mild to moderate traumatic brain injury (TBI) to evaluate the effects of brain trauma on regional cerebral blood flow (rCBF). SPECT scan was compared with CT scan in 16 patients. SPECT showed intraparenchymal differences in rCBF more often than lesions diagnosed with CT scans (87.5% vs. 37.5%). In five of six patients with lesions in both modalities, the area of involvement was relatively larger on SPECT scans than on CT scans. Contrecoup changes were seen in five patients on SPECT alone, two patients with CT alone and one patient had contrecoup lesions on CT and SPECT. Of the eight patients (50%) with skull fractures, seven (43.7%) had rCBF findings on SPECT scan and five (31.3%) demonstrated decrease in rCBF in brain underlying the fracture. All these patients with fractures had normal brain on CT scans. Conversely, extra-axial lesions and fractures evident on CT did not visualize on SPECT, but SPECT demonstrated associated changes in rCBF. Although there is still lack of clinical and pathological correlation, SPECT appears to be a promising method for a more sensitive evaluation of axial lesions in patients with mild to moderate TBI.     

Splenic injury in children: a 10 year experience

The aim of this report was to review retrospectively the management of splenic trauma at a major Australian tertiary referral centre (Westmead Hospital) over a 10 year period. Forty-nine patients (0-15 years of age) with documented blunt splenic trauma were identified. The causes of splenic injury were road trauma (73%) and falls (27%). There were 22 minor injuries (Injury severity score [ISS] < 16) and 27 severe injuries (ISS > or = 16). All nine deaths were related to road trauma (mean ISS = 59). The investigation most commonly used was CT scanning (47%). Peritoneal lavage was performed in six patients (12%). Management involved non-operative care in 29 patients (57%), exploratory laparotomy alone in 5 (10%), splenic salvage in 2 (4%) and splenectomy in 13 (26%). This experience supports the view that non-operative management of splenic injury in haemodynamically stable children is safe and is the preferred treatment. Experienced assessment and meticulous observation is necessary. Laparotomy is indicated if there is continuing haemodynamic instability despite resuscitation. Operative management is aimed at splenic salvage with splenectomy being reserved for uncontrolled haemorrhage.     

Angiotensin II interferes with leukemia inhibitory factor-induced STAT3 activation in cardiac myocytes

BACKGROUND: The 24-hour observation critical pathway for trauma is a clinical tool developed to expedite health care delivery to minimally injured patients. The use of patient care, BS, guidelines and physician-approved standing orders was implemented in a Level I trauma center. METHODS: A retrospective chart review was performed of 122 patients admitted via the emergency department between December 1, 1993, and May 31, 1994. All patients were evaluated in the emergency department by emergency medicine and trauma physicians and deemed appropriate for 24-hour observation. The information collected included patient demographics, hospital charges, injuries, length of stay, diagnostic tests, consultations, and variances from the critical pathway. RESULTS: During the 6-month study period, there were 600 trauma admissions. Of those admissions, 122 patients (20%) were evaluated in the emergency department and deemed appropriate for enrollment in the 24-hour observation pathway. The charts of these patients were reviewed. Fourteen admissions were determined inappropriate for the critical pathway because of the severity of injuries or discharge against medical advice. One hundred eight charts were evaluated further. Eighty-nine patients (80%) completed the critical pathway with a length of stay of 24 hours. CONCLUSION: The 24-hour observation critical pathway was designed and used appropriately as exemplified by an overall 80% completion rate. The critical pathway offers a mechanism to streamline care of the minimally injured trauma patient. It also serves as a quality-improvement tool for increasing efficiency, decreasing utilization of resources, and decreasing length of stay.
