BACKGROUND: Suicide is an important public health concern. Firearms are the most common mechanism of suicide death. This study describes the epidemiology of fatal and nonfatal firearm suicide injuries (FSI) in one metropolitan area from 2002 through 2004 using a firearm injury surveillance system. METHODS: Records were obtained of all victims of firearm injuries from hospitals, police, and the coroner. All injuries categorized as suicide were included. RESULTS: Local age adjusted suicide rates were significantly higher than state or national rates for ages 15 to 24, and significantly higher than national rates for ages 25 to 44. Men were FSI victims more than five times as often as women were. There was no seasonal pattern identified. Handguns were used nearly three out of four times. Eighty-six percent of FSI victims died, two-thirds at the scene. Most wounds were in the head or chest. Mental illness or relationship problems were common. Most suicides occurred in a residence. CONCLUSIONS: Community level firearm injury surveillance effectively identifies local trends that may differ from national statistics. Collaboration among various groups is used to support injury prevention programs. These data can both complement and contribute to national statistics. Language: en

Background: The medical benefits of trauma centers have been well documented; studies have reported substantial financial losses attributed to trauma care. This study demonstrates the dependence of Level I trauma centers on Disproportionate Share Hospital (DSH) governmental funds and tax dollars. Furthermore, specific injury groups have greater dependence on these funds. Methods: Records of 553 trauma patients admitted to a public urban Level I trauma center during a 6-month period were reviewed. Patients were grouped according to blunt, penetrating, and thermal injuries. Data for each group included charges, costs, payments, and the source of reimbursement. Profit and loss margins were compared with and without government funds. Results: With diminished DSH funds and tax dollars, a net loss over $2.1 million was incurred. The greatest disparity originates from Medicaid, self-pay, and prisoner patient groups. Inclusion of government funds provided a positive return of over $600,000. Conclusion: The financial stability of urban public level I trauma centers without additional funding is tenuous because of a high proportion of uninsured and underinsured patients. Government tax dollars and DSH funds are required for their continued solvency.

Objective : To analyze the indications for and the success rate, complications, and neurologic outcomes of surgical cricothyroidotomy when performed in the field by ambulance paramedics. Methods : The ambulance and hospital records of all trauma patients on whom a surgical cricothyroidotomy was attempted in the field by ambulance paramedics over a 5-year period were reviewed. A telephone survey of survivors was used to assess long-term complications and neurologic outcome. Results : Surgical cricothyroidotomy was attempted on 50 patients, or 9.8% of those requiring definitive airway control. The most common indications were clenched teeth, blood or vomit obscuring visualization of the upper airway, severe maxillofacial injuries, and inaccessibility because the patient was trapped. Airway establishment was successful in 47 patients (94%). Major complications occurred in 2 patients (4%), where inadvertent dislodgement of the tube developed, requiring replacement. No patient developed significant subglottic stenosis. Nineteen patients (38%) survived and no patient died because of an inadequate airway. Evaluation of neurologic outcome revealed 12 patients (63%) with no significant deficits, 3 (16%) with moderate disability, 2 (10%) with severe disability, and only 2 in a persistent vegetative state. Conclusions : Surgical cricothyroidotomy can be performed on the critically injured patient in the field by ambulance paramedics with a high success rate and a low complication rate. The use of surgical cricothyroidotomy should be included in airway protocols for well-trained, ambulance Advanced Life Support paramedics.

Because of difficulties in rapid exposure and control, injuries of the retrohepatic veins and retrohepatic vena cava continue to have mortality rates approaching 100%. Current strategies include shunt and finger fracture techniques, with controversy continuing over the optimal approach. We describe a new technique which involves mobilization of the liver by transecting the superhepatic vena cava, and affords a posterior approach to these injuries. Cadaveric dissection and clinical experience are described.

We reviewed 72 patients with penetrating trauma to the extremities who underwent arteriography for proximity injury only. None of the patients had clinical evidence of vascular trauma. There were 62 males and ten females, with a mean age of 29.9 years. Gunshot wounds were the most common cause of injury (91.7%) and the thigh was the most common site of injury (47.2%). A normal arteriogram was found in 55 of 72 patients (76.4%). The remaining 17 patients (23.6%) had arteriographic abnormalities that did not warrant surgery. Only one patient was explored (1.4%) for spasm of the popliteal artery. No vascular injury was found at surgery. This study suggests that routine arteriography in proximity injury only may be unnecessary and that these patients could safely be admitted to the hospital for a 24-hour period of observation.

We prospectively evaluated the efficacy of comprehensive field triage in 8,891 trauma patients transported to trauma centers in Dade County, Florida, over a 1-year period ending in September 1986. There were 5,685 males (63.9%) and 3,206 females (36.1%) with a mean age of 32.4 +/- 18.4 years. The overall accuracy for identifying severe injury for the entire group was 30.2%. A Trauma Score less than or equal to 12 was the most accurate predictor of severe injury. Of 669 patients in this group, 617 (92.2%) sustained severe injury and 361 died (54.0%). High-speed (greater than 40 m.p.h.) motor vehicle accident was the most common reason for triage; however, of 2,277 in this group 201 patients (9.0%) had severe injury and four patients (0.2%) died. Only nine deaths (0.9%) occurred in 1,004 patients with penetrating trauma whose Trauma Scores were greater than 12. Of the 8,891 patients 4,791 (53.9%) had moderate to severe injury. The overtriage rate was therefore 46.1% using this field categorization system.

In order to reassess the value of diagnostic peritoneal lavage (DPL) in patients with blunt abdominal trauma, we conducted a prospective study over a 15-month period involving 138 patients. There were 29 (28.3%) patients with positive DPL and 103 (71.7%) with negative DPL in this series. Of the 29 patients with positive DPL, 28 (96.5%) were found to have significant intra-abdominal injuries; 27 by exploratory laparotomy and in one case at autopsy. One patient with a grossly positive DPL had a negative exploratory laparotomy (3.4% false positive rate). All 109 patients with negative DPL were admitted. In only one case a significant intra-abdominal injury was demonstrated (0.9% false negative rate). The overall mortality in this series was 11.6% and there were no complications related to the DPL. Our results suggest that DPL is indeed an accurate indicator of significant intra-abdominal injuries in patients with blunt abdominal trauma.
