Proportion of seriously injured patients admitted to hospitals in the US with a high annual injured patient volume: a metric of regionalized trauma care

BACKGROUND: Multiple regional trauma systems have been implemented over the past 3 decades to achieve the goal of regionalized care for injured patients. The American College of Surgeons Committee on Trauma (ACS-COT) advocates that seriously injured patients should be treated in designated Level I trauma centers that meet criteria including admitting more than 1,200 injured patients annually. Reliable measures are needed to evaluate the implementation of regionalized care nationally. The goal of this study was to measure the proportion of seriously injured patients treated at high injury-volume hospitals. STUDY DESIGN: We performed a retrospective observational study of injured patients hospitalized in the US during the years 1995 to 2003, drawn from the Nationwide Inpatient Sample. Hospitals were ranked in order of annual volume of injured patient admissions. A patient's severity of injury was calculated using ICD-9-based Injury Severity Score (ICISS). The principal measure was the proportion of seriously injured patients (ICISS相似文献   

Multidisciplinary approach to the patient with multiple trauma: a case report

A multidisciplinary approach to severe polytraumatized patient is very important for a rapid, uncomplicated recovery. Specialized centres with special beds, monitoring equipment, and a multidisciplinary team are required. The authors report a case of a 26-year-old man admitted to their department in an emergency setting for a crush injury (occupational trauma) of the lumbar, gluteal and perineal areas, complicated with septic shock and gas gangrene of the injured areas. A multidisciplinary approach to the patient, consisting in surgical and plastic surgical therapy, hyperbaric oxygen therapy and the use of a special antidecubitus fluidized bed allowed complete recovery within 7 months without any motor or sphincter disorders.     

The multiple injured patient with bladder trauma

Trauma of the bladder from external force is associated with severe multiple injuries and the resulting mortality rate is substantial. The major associated injury was fracture of the pelvic bones which was present in 346 (83%) of the 417 patients with bladder trauma. Contusion of the bladder was present in 280 (67%), intraperitoneal rupture in 53 (13%), extraperitoneal rupture in 76 (18%), and both intra- and extraperitoneal rupture in eight (2%). Radiologic evaluation of the bladder by a retrograde cystogram using 400 ml of dye is recommended to diagnose the type of bladder injury. Nonoperative (catheter) management of extraperitoneal rupture of the bladder was used in 18 patients and resulted in complications in four of the 18.     

Pediatric trauma nurse practitioners provide excellent care with superior patient satisfaction for injured children

Purpose

Work hour restrictions for house staff have forced a reevaluation of the traditional roles of all health care providers. In 2001, our level I pediatric trauma center augmented the role of our trauma pediatric nurse practitioners (PNPs) to include in-patient management. We hypothesized that a PNP can provide injured children a level of care commensurate with a resident (RES).

Methods

All children between 2 months and 17 years old admitted to the Trauma Service were considered for the study. Patients were randomized to PNP or RES care groups. Types of injuries, injury severity score, missed injuries, readmissions, hospital length of stay (LOS), and cost were recorded. Satisfaction surveys were administered to all families.

Results

A total of 76 children were enrolled. During the study period, there were no missed injuries or readmissions. The PNP group had a significantly shorter LOS and received significantly higher satisfaction survey scores with regard to information on injuries, tests and treatment, and frequency of visits provided to the patient/family.

Conclusions

PNPs provide equivalent care for injured children with significantly shorter LOS and higher patient satisfaction than RESs. In-patient trauma nurse practitioners provide added value to the care of the injured child in the era of reduced RES work hours.     

Influence of trauma system implementation on process of care delivered to seriously injured patients in rural trauma centers

BACKGROUND: Statewide trauma systems are implemented by health care policy makers whose intent is to improve the process of care delivered to seriously injured patients. In Oregon, Advanced Trauma Life Support (ATLS) training was mandated for all physicians employed in the emergency department of trauma centers. The purpose of this study was to test the hypothesis that mandatory ATLS training favorably influenced processes of care. METHODS: Seriously injured patients treated at 9 rural Level 3 and Level 4 hospitals were studied before (PRE) and after (POST) implementation of Oregon's trauma system. The processes of care evaluated on the basis of chart review were 20 diagnostic and therapeutic interventions advocated in the ATLS course. A cumulative process score (CPS) between 0 and 1 was assigned on the basis of the processes of care delivered. A CPS of 1 indicated optimal process of care. RESULTS: Mean CPS for 506 PRE period patients (0.44 +/- 0.27) was significantly lower than the mean CPS for 512 POST period patients (0.57 +/- 0.27) with an unpaired t test (P <.001). For the subgroup with injury severity score of 16 to 34, the mean CPS of survivors (0.67 +/- 0.19) was significantly higher than the mean CPS of decedents (0.57 +/- 0.25). CONCLUSIONS: Process of care for seriously injured patients improved after categorization of rural trauma centers in Oregon. Evidence shows improved process of care may have benefitted patients with serious but survivable injuries. Measurement of process of care is an alternative to mortality analysis as an indication of the quality of care.     

Prehospital care of the patient with an injured chest

The trauma patient with thoracic injury poses special problems for the paramedic. A chest injury frequently is a signal of other injury and alerts the paramedic to transport the patient to the regional trauma center, regardless of triage criteria applicable in any general area. In patients with chest injury, fluids should be judiciously administered, and pneumatic garments should NOT be applied. Trocar chest tubes should be avoided. Airway management is of prime importance, and the airway can be assured and protected by the paramedics. As time is of prime concern, the patient with thoracic injury should be transported as soon as possible to a regional trauma center. For distances of less than 35 miles, advanced life-support ground ambulances are preferable to air ambulances.     

Occult orthopaedic trauma in the multiply injured patient

A retrospective review of 111 multitrauma patients revealed that of 401 orthopaedic injuries, 24 injuries (6%) were not initially diagnosed in 20 patients. Patients with occult injuries tended to have greater overall trauma, as reflected by lower trauma and lower Glasgow coma scores and longer hospital and intensive-care unit stays. Twenty prospectively identified cases were added to the series to further define risk factors. Seventy percent of occult bony injuries were ultimately diagnosed by physical examination and plain radiographs alone. Only 27% of cases required sophisticated imaging techniques for diagnosis. Based on these 44 cases of occult injuries in multitrauma victims, the following risk factors were identified: (1) significant multisystem trauma with another more apparent orthopaedic injury within the same extremity, (2) trauma victim too unstable for full initial orthopaedic evaluation, (3) altered sensorium, (4) hastily applied emergency splint obscuring a less apparent injury, (5) poor quality or inadequate initial radiographs, and (6) inadequate significance assigned to minor signs/symptoms in a major trauma victim. Due to the nature and extent of the overall trauma, all injuries cannot be diagnosed on initial patient evaluation.     

Renal trauma in the multiple injured patient.

Immediate radiological evaluation of renal injuries by a large dose or infusion excretory urogram resulted in a definitive diagnosis in 87% of the cases. Further radiological evaluation or exploration was required to make a definitive diagnosis in the remaining 13%. Blunt external trauma was responsible for 94% of the renal injuries. Less morbidity and a sharp reduction in delayed renal operation followed the introduction of immediate surgical management with the more severe types of renal injury. Clamping of the renal vessels prior to opening Gerota's fascia prevents reactivation of hemorrhage and allows for a deliverate operation with conservation of undamaged renal tissue. Associated injuries were present in 73% of the patients, including intra-abdominal injuries in 42%. The over-all nephrectomy rate of 5% in this study compares favorably to the nephrectomy rate in studies reporting the expectant management of renal injuries.     

Diagnostic approach to the patient with jaundice following trauma.

BACKGROUND AND AIMS: Jaundice in trauma patients may reflect serious underlying pathology. The aim of this review was to determine the appropriate diagnostic approach to the patient with jaundice following trauma. METHODS: A MEDLINE search was performed to retrieve publications which outlined the causes of jaundice in trauma patients. RESULTS: The main causes of jaundice in trauma patients were found to be bilirubin overload caused by breakdown of transfused- and extravasated blood and hepatic dysfunction caused by sepsis, infections, initial shock and systemic hypotension. Bile duct injury or drug induced liver injury are rare. Liver function tests are often uninformative but commonly show a cholestatic pattern. Ultrasound, CT or ERCP are the diagnostic imaging methods most widely used. Abdominal ultrasound and CT may reveal specific organ injuries, bile duct dilatation, intraabdominal fluid collections, hematomas or acalculus cholecystitis. ERCP is often diagnostic and permits a therapeutic intervention when a bile duct injury is present. CONCLUSIONS: The primary aim of the diagnostic approach should be to identify all cases of bile duct injury or obstruction. Sepsis and infections should be actively looked for. The number of blood transfusions must be calculated. Ultrasound, CT or ERCP are the diagnostic imaging methods most widely used.     

Integrating emergency general surgery with a trauma service: impact on the care of injured patients

BACKGROUND: There has been considerable discussion on the national level on the future of trauma surgery as a specialty. One of the leading directions for the field is the integration of emergency general surgery as a wider and more attractive scope of practice. However, there is currently no information on how the addition of an emergency general surgery practice will affect the care of injured patients. We hypothesized that the care of trauma patients would be negatively affected by adding emergency general surgery responsibilities to a trauma service. METHODS: Our institution underwent a system change in August 2001, where an emergency general surgery (ES) practice was added to an established trauma service. The ES practice included emergency department and in-house consultations for all urgent surgical problems except thoracic and vascular diseases. There were no trauma staff changes during the study period. Trauma registry data (demographics, injuries, injury severity, and procedures) and performance improvement data (peer-review judgments for all identified errors, denied days, audit filters, and deaths) were abstracted for two 15-month periods surrounding this system change. Chi-square, Fisher's exact, and t tests provided between-group comparisons. RESULTS: The trauma staff evaluated a total of 5,874 patients during the 30-month study. There were 1,400 (51%) trauma admissions in the pre-ES group and 1,504 (48%) in the post-ES group, of which 1,278 and 1,434, respectively, met severity criteria for report to our statewide database (Pennsylvania Trauma Outcome Study [PTOS]). There were 163 (12.7% of PTOS) deaths in the pre-ES group compared with 171 (11.9% PTOS) deaths in the post-ES group (p = not significant [NS]). There was one death determined to be preventable by the peer review process for the pre-ES group, and none in the post-ES group. Both groups had 10 potentially preventable deaths, with the remaining mortalities being categorized as nonpreventable (p = NS). Unexpected deaths by TRISS methodology were 36 (2.8%) and 41 (2.9%) for the two groups, respectively (p = NS). There was no difference in the number of provider-specific complications between the groups (23, [1.8%] vs. 19 [1.3%], p = NS). The addition of emergency surgery has resulted in an additional average daily workload of 1.3 cases and 1.2 admissions. CONCLUSION: Despite an increase in trauma volume over the study period, the addition of emergency surgery to a trauma service did not affect the care of injured patients. The concept of adding emergency surgery responsibilities to trauma surgeons appears to be a valid way to increase operative experience without compromising care of the injured patient.     

Remifentanil in the ICU: a new approach to patient care

In recent years, it has become increasingly common practice to sedate patients continuously during their stay in intensive care units (ICUs). The aim has been to keep them calm and comfortable, avoid anxiety and agitation and facilitate processes such as ventilatory support, tracheostomy and extubation. In large part this trend has been due to the availability of the new sedative/hypnotic agents propofol and midazolam, which can provide effective long-term sedation.The focus on sedation (which might more properly be termed hypnosis, since its aim is to make the patient sleepy) has been at the expense of a more precise attention to analgesia. Today we usually titrate the sedative to effect, and consider pain relief as adjunctive therapy. The consequence of this approach is that often our patients are over-sedated. This not only brings the danger of increased morbidity and mortality, it also increases costs, through the need for a greater number of expensive tests such as CAT scans of the brain, prolonged mechanical ventilation and longer stays in both the ICU and hospital. Furthermore, many patients in the ICU continue to feel pain and complain of insufficient analgesia.In future, we should concentrate on pain relief first and add sedation and anxiolysis as and when necessary. Analgesia will in itself relieve much anxiety and many patients will not require sedatives at all.The adoption of a ‘pain relief first’ policy has in the past, however, been hampered by the lack of suitable opioids, due to their unpredictability and their slow onset and offset times. The introduction of a new opioid, remifentanil, should overcome these difficulties. Remifentanil is a new and novel opioid. Unlike many other opioids, which are non-specific, it is selective for the μ receptors that mediate pain. It has uniquely predictable effects, including a rapid onset time (around 1min) and a rapid offset (recovery) time (<10min). This mode of action allows the depth of analgesia to be quickly titratable to the patient's needs. It also means a reduced use in sedative/hypnotic drugs such as propofol and midazolam.The consequences should be an improvement in patient care (not least in better communications between patients, relatives and carers), a reduction in costs and a more efficient use of resources. Improvements in morbidity and mortality might also be expected. Further detailed studies need to be carried out to confirm that routine analgesia with remifentanil improves patient comfort, reduces mortality and mortality and cuts costs.     

The injured elderly in the trauma intensive care unit

The injured elderly patient in the ICU presents many challenges. Demographic changes in western society will dramatically increase the patient population in question, and new, older, subsets are growing. The association of severe injury, preinjury comorbidity, and the aging process narrows the ability of the patient to respond to the stress of injury. When compared with younger patients, the elderly have greater mortality, morbidity, and higher costs. Age alone, however, does not predict outcome. Although aggressive or maximally supportive care is advocated, controlled data supporting this approach are lacking. Significant economic, sociologic, and ethical issues confront the care providers in almost every case. Continued and heightened study of all aspects of our injured elders focusing on the determinants of outcome is required. A realistic appraisal of the limitations of care and a reassessment of the financial implications of providing extended care are critical to the continuing ability to respond to this growing need.
