Improved nurse job satisfaction and job retention with the transition from a "mandatory consultation" model to a "semiclosed" surgical intensive care unit: a 1-year prospective evaluation.
OBJECTIVE: The change from a "mandatory consultation" to a "semiclosed" surgical intensive care unit (SICU) model will impact nurses considerably. We hypothesize that nurse job satisfaction, job turnover rates, and hospital costs for temporary agency nurses will improve and these improvements will be more dramatic in SICU sections with greater involvement of a dedicated surgical critical care service (SCCS). DESIGN: Prospective longitudinal survey. SETTING: Tertiary-care university hospital. SUBJECTS: SICU staff nurses. INTERVENTIONS: Change from mandatory consultation to semiclosed SICU. MEASUREMENTS AND MAIN RESULTS: We surveyed SICU nurses during the year-long transition to a semiclosed SICU service (five time points, 3-month intervals). The first four surveys included ten questions on nurse job satisfaction. The final survey included two additional questions. All questions were on a 5-point Likert scale (1 = strongly disagree to 5 = strongly agree). Nurse job turnover rates and money spent on agency nurses were compared over time; 503 of a possible 914 surveys were completed (55% overall return rate). Nurse job satisfaction scores significantly improved over time for all questions (p < .05). Hospital spending on agency nurses decreased significantly (p = .0098). The yearly nurse job turnover rate dropped from 25% to 16% (p = .15). The scores for both year-end statements ("I am more satisfied with my job now than 1 year ago" and "The SCCS management of all orders has improved my job satisfaction") were significantly higher in sections with greater SCCS involvement (p = .0070 and p < .0001). CONCLUSIONS: Nurse job satisfaction improved significantly with the transition to a semiclosed SICU. This higher satisfaction was associated with a significant decrease in spending on temporary agency nurses and a trend toward increased staff nurse job retention. SICU sections with greater SCCS involvement had more dramatic improvements. This semiclosed SICU model may help retain SICU nurses in a competitive job market in which experienced nurses are in short supply.

Analgesic use in intubated patients during acute resuscitation.
BACKGROUND: Pain relief can often be overlooked during a busy trauma resuscitation, especially in patients who are intubated. We sought to investigate qualitative and quantitative aspects of analgesic use in intubated patients during the acute phase of resuscitation. METHODS: We evaluated a retrospective cohort of consecutive adult patients who were intubated during the acute trauma resuscitation (first 6 hours) from January 2001 to May 2002 at a Level I trauma center in the United States. Patient demographics, injuries, vital signs, medications, trauma bay procedures, and disposition status were analyzed. Analgesia was recorded as the type of analgesic, route of administration, elapsed time to receive the first analgesic, total dosage, and time intervals between two successive doses. Fisher's exact test, chi test, and ANOVA were used to analyze data. RESULTS: A total of 120 patients were included. Sixty-one (51%) patients received analgesia during their stay in the emergency department. Using logistic regression analysis, patients who more likely to receive analgesia were those who did not require immediate surgical operation and were transferred to the intensive care unit (odds ratio [OR]=3.91; 95% CI=1.75-8.76) and those who were admitted during the hours of 8 am to 6 pm (OR=3.17; CI=1.40-7.16). Among those patients receiving analgesia, 30 (25%) patients received analgesia within 30 minutes upon arrival. The mean time of receiving the first analgesia dose was 57 minutes. The average morphine equivalent dose given to the patients was 15.7 mg. The most frequently given single dose was 100 mug of intravenous fentanyl. Most of the analgesics (37%) were given between 30 to 60 minutes apart. CONCLUSION: Our findings suggest that patients who are intubated during the acute resuscitation probably receive inadequate analgesia. The inadequacy appears to be in the timing and repetition of administration, rather than the dose. Patients who were transferred early to the intensive care unit were more likely to receive analgesics.

Maintaining patient throughput on an evolving trauma/emergency surgery service.
BACKGROUND: The case-management team (CMT) has been an effective tool to decrease denied days and improve hospital throughput on a trauma service. With the addition of emergency general surgery (EGS) to our practice, we reviewed the ability of the case management team to absorb EGS patients on the inpatient trauma service while maintaining the improvements initially realized. METHODS: An interdisciplinary CMT was implemented in January 1999. CRNPs were added in August 2003 to address the Accreditation Council for Graduate Medical Education resident work-hour restrictions. "Key communications" for each CMT member are reported three times per week as defined by a hospital-approved policy. Beginning in August 2001, the trauma service was expanded to include EGS patients. Data from the trauma registry, hospital utilization review, and finance office were analyzed before (1998 and 1999) and after (2003 and 2004) the addition of EGS. Tests of proportion were used to evaluate questions of interest. RESULTS: The number of injured patients admitted to the trauma service remained relatively constant during the study periods, ranging from a high of 1,365 in 1999 to a low of 1,116 in 2003. Beginning in 2003, the influx of emergency surgery patients to the service was marked. By 2004, there were 561 emergency surgery admissions, representing more than 30% of the total service admissions. As a result, the total number of service admissions has dramatically increased, reaching 1,833 in CY 2004, a 56% increase from CY 1998 levels. Hospital length of stay data varied from a low of 5.5 days in CY 1999 to a high of 6.9 days in CY 2003. Length of stay appeared to be associated with injury severity (mean Injury Severity Score 11.8 in 1999 and 13.1 in 2003) and case mix, but not associated with denied days. The percent of denied days decreased over the study periods, from 4.6% in 1998 (before the implementation of the CMT) to 0.5% in 2004 (p<0.01). The percent of readmissions also fell significantly over the study periods (4.0% in 1998 to 1.8% in 2004; p<0.01). CONCLUSIONS: The initial improvements in patient throughput noted after the introduction of a CMT in January 1999 have been maintained in recent years despite the addition of an EGS component to the trauma service. Percent denied days and readmissions have continued to decrease. The length of stay for these patients remains, in part, dependent on other factors. The CMT plays an integral role in maintaining the efficiency of a trauma/emergency surgery service.

Anemia management program reduces transfusion volumes, incidence of ventilator-associated pneumonia, and cost in trauma patients.
BACKGROUND: Strategies to restrict transfusions are gaining acceptance in critical care. We implemented an anemia management program (AMP) for trauma patients in the Surgical Intensive Care Unit. AMP was based on a transfusion trigger of 7 g/dL hemoglobin once hemodynamic sufficiency was achieved. We hypothesized that AMP would decrease the transfusion of packed red blood cells (PRBCs) and cost without detriment in clinical outcomes. METHODS: Transfusion data were retrospectively collected for all trauma patients treated in our Surgical Intensive Care Unit between July 2002 and December 2003. AMP was implemented in a step-wise fashion during a 6-month period (January to June 2003). Data were compared for the 6-month period before (Group I, July to December 2002) and after (Group II, July to December 2003) complete AMP implementation. Blood transfusion volumes were compared using negative binomial regression. Clinical outcomes (length of stay [LOS], death, myocardial infarction [MI], and ventilator-associated pneumonia [VAP]) were compared using risk ratios. Age, sex, and injury severity score (ISS) were examined as potential confounders. RESULTS: In all, 514 trauma patients were treated during the study period (n = 270 in Group I and n = 244 in Group II). Group I and Group II were similar in age (mean: 43.6 versus 42.9) and ISS (mean: 18.3 versus 17.0). Mean PRBCs per patient transfused decreased from 23.1 units to 17.1 units (p = 0.057), reflecting a 22.5% reduction adjusted for confounders (p = 0.097). Outcome data revealed no differences in LOS (mean: 6.4 versus 5.9, p = 0.920), risk of death (4.1% versus 6.1%, p = 0.158), or MI (0.7% versus 0.8%, p = 0.974), but a significant reduction in the incidence of VAP (8.1% versus 0.8%, p = 0.002). Total PRBC cost decreased during the study period from 503,000 dollars to 397,000 dollars. CONCLUSIONS: An anemia management program appears to be safe when applied in the acute ICU phase of trauma care. Implementation of AMP in the ICU reduced the volume of PRBCs transfused with significant cost savings. No significant differences in length of stay, mortality rate, or MI rate were seen. The significant decrease in the rate of VAP requires further elucidation. Further long-term and larger studies are indicated.

Access to trauma centers in the United States.
CONTEXT: Previous studies have reported that the number and distribution of trauma centers are uneven across states, suggesting large differences in access to trauma center care. OBJECTIVE: To estimate the proportion of US residents having access to trauma centers within 45 and 60 minutes. DESIGN AND SETTING: Cross-sectional study using data from 2 national databases as part of the Trauma Resource Allocation Model for Ambulances and Hospitals (TRAMAH) project. Trauma centers, base helipads, and block group population were counted for all 50 states and the District of Columbia as of January 2005. MAIN OUTCOME MEASURES: Percentages of national, regional, and state populations having access to all 703 level I, II, and III trauma centers in the United States by either ground ambulance or helicopter within 45 and 60 minutes. RESULTS: An estimated 69.2% and 84.1% of all US residents had access to a level I or II trauma center within 45 and 60 minutes, respectively. The 46.7 million Americans who had no access within an hour lived mostly in rural areas, whereas the 42.8 million Americans who had access to 20 or more level I or II trauma centers within an hour lived mostly in urban areas. Within 45 and 60 minutes, respectively, 26.7% and 27.7% of US residents had access to level I or II trauma centers by helicopter only and 1.9% and 3.1% of US residents had access to level I or II centers only from trauma centers or base helipads outside their home states. CONCLUSION: Selecting trauma centers based on geographic need, appropriately locating medical helicopter bases, and establishing formal agreements for sharing trauma care resources across states should be considered to improve access to trauma care in the United States.

Bilateral dismembered laparoscopic pediatric pyeloplasty via a transperitoneal 4-port approach.
PURPOSE: Laparoscopic pyeloplasty is gaining acceptance for the treatment of ureteropelvic junction obstruction in the pediatric population, with success rates approaching those of traditional open pyeloplasty. We report our technique with a transperitoneal 4-port approach and positioning method, allowing bilateral laparoscopic dismembered pyeloplasty with 1 uninterrupted sterile field. MATERIALS AND METHODS: Two children were diagnosed with bilateral ureteropelvic junction obstruction. Following cystoscopic ureteral stent placement operative positioning was achieved with intravenous pressure infuser bags placed under each side of the patient and rotation of the table to a lateral decubitus position. Four-port transperitoneal access was used to perform bilateral dismembered pyeloplasty with interrupted 6-zero polyglactin sutures. RESULTS: Both patients had bilateral crossing vessels to the lower pole of the kidneys. Total operative time was 268 minutes and 284 minutes for the 8-year-old and the 14-year-old, respectively. The ureteral stents were removed separately at 6 and 8 weeks after repair with the patients under sedation. CONCLUSIONS: Bilateral laparoscopic pyeloplasty appears feasible for the pediatric patient.

The invisible trauma patient: emergency department discharges.
BACKGROUND: As the malpractice and financial environment has changed, injured patients evaluated by the trauma team and discharged from the emergency department (ED) are now commonplace. The evaluation, care, and disposition of this population has become a significant workload component but is not reported to accrediting organizations and is relatively invisible to hospital administrators. Our objective was to quantify and begin to qualify the evolving picture of the trauma ED discharge population as a work component of trauma service function in an urban, Level I trauma center with an aeromedical program. METHODS: Trauma registry (contacts, mechanism, transport, injuries, and disposition) and hospital databases (ED closure, occupancy rates) were queried for a 5-year period (1999-2003). Trend analysis provided statistical comparisons for questions of interest. RESULTS: During the 5-year study period, the total number of trauma contacts rose by 18.1% (2,220 in 1999 vs. 2,622 in 2003; trend p < 0.05). This increase in total contacts was not a manifestation of an increase in admissions (1,672 in 1999 vs. 1,544 in 2003) but rather a reflection of a marked increase in patients seen primarily by the trauma team and discharged from the ED (473 in 1999 vs. 1,000 in 2003; trend p < 0.05). These ED discharge patients were increasingly transported by helicopter (12.3% in 1999 vs. 29.2% in 2003; trend p < 0.05) and less frequently from urban areas (57.1% in 1999 vs. 48.1% in 2003; trend p < 0.05) over the course of the study period. Average injury severity of this group increased over the study period (Injury Severity Score of 2.7 +/- 0.1 in 1999 vs. 3.3 +/- 0.1 in 2003; trend p < 0.05). ED length of stay for this group increased 19.8% over the study period (trend p < 0.05), averaging nearly 5 hours in 2003. CONCLUSION: The total number, relative percentage, and injury severity of patients evaluated by the trauma team and discharged from the ED has significantly increased over the last 5 years, representing nearly 5,000 patient care hours in 2003. Systems to care for these patients in a cost- and resource-efficient fashion should be put in place. The impact of this growing population of patients on the workload of the trauma center should be recognized by accrediting agencies, hospital administration, and Emergency Medical Services.

The evolving role of interventional radiology in trauma care.
BACKGROUND: Although the traditional role of radiology in trauma care has been diagnostic, therapeutic interventional radiology (IR) techniques have now become essential in the management of many injuries. We hypothesized that IR has evolved at our institution over the last decade from a largely diagnostic to a more therapeutic role in the care of the injured patient. METHODS: Demographic information, computed tomographic scans of the chest and abdomen, and angiographic procedures (APs) performed within 48 hours of admission were reviewed in all patients evaluated at a Level I trauma center for the periods 1993 to 1995 and 2000 to 2002. All APs performed with the intent to embolize, stent, or insert a device into a vessel were designated as therapeutic. Analysis by means of chi provided between-group comparisons for questions of interest and the Student's t test was used for comparison of means. RESULTS: A total of 4,750 patients were reviewed, 1,677 from the time period 1993 to 1995 and 3,073 from the period 2000 to 2002. Overall injury severity as measured by the Injury Severity Score (ISS) was similar in both groups (9.6 vs. 9.9, p = not significant). The number of angiograms obtained decreased significantly from 7.1% to 4.0% of all patients (p < 0.01). Concurrently, the fraction of all angiograms that were considered therapeutic rose from 10% to 22% (p < 0.05). The overall number of aortic arch angiograms decreased over time (from 3.6% to 0.9%, p < 0.01), and the percentage of positive examinations increased from 5.0% to 21.4%. In comparison, the number of computed tomographic scans of the chest increased from 1.6% of all patients to 10.8% (p < 0.01). CONCLUSION: Axial imaging studies are being used more frequently to screen trauma patients for injury. Concurrently, diagnostic APs are less frequently performed but are more frequently positive. In addition, IR studies are increasingly focused on therapeutic intervention. IR program development and support is an integral aspect of modern trauma care. These findings have prompted our institution to equip the IR suite to function as an active resuscitation area similar to the trauma bay and intensive care unit.

Use of goniometry to predict inadequate flexion-extension roentgenograms: a preliminary study.
BACKGROUND: Flexion-extension roentgenograms (FER) of the cervical spine are often inadequate because of limited range of motion (ROM). The purpose of this study was to determine the utility of goniometry to predict a patient's ability to achieve sufficient ROM to obtain adequate FER. METHODS: We evaluated 65 consecutive blunt trauma patients undergoing evaluation by FER in the emergency department. Patients were evaluated by goniometry before performing FER. Adequate ROM was defined as flexion and extension of >30 degrees from neutral. RESULTS: Seventy-five percent of patients had adequate FER. All of these patients were predicted to have sufficient ROM by goniometry. Goniometry predicted limited ROM in 69% of patients who had inadequate FER. The positive predicative value of goniometry in predicting inadequate FER was 100%. The incidence of cervical spine injuries was 44% in patients with inadequate ROM by goniometry and 23.0% in patients with inadequate FER (versus 7.69% in patients with adequate FER). CONCLUSION: Goniometry accurately predicted those patients who were unable to achieve sufficient ROM for adequate FER. Patients with inadequate FER were at a higher risk for cervical spine injury compared with patients with adequate FER (23.0 versus 7.69%). Early identification of these patients will help limit the number of inadequate studies obtained and expedite evaluation of high-risk patients.

The inefficiency of plain radiography to evaluate the cervical spine after blunt trauma.
BACKGROUND: Controversy persists regarding the most efficient and effective method of cervical spine evaluation after blunt trauma. Historic guidelines for patients undergoing computed tomography (CT) of the head advocate imaging the occiput-C2 as part of that study. For the remaining cervical spine, plain cervical spine radiographs (CSR) with supplemental CT are recommended. Many patients who require head CT also undergo supplemental cervical spine CT after plain CSR, which leads to separate, discontinuous cervical spine CT scans. We sought to determine the incidence of this in our population. We hypothesized that plain CSR alone often proves inadequate to evaluate the cervical spine in patients who require head CT. METHODS: The Eastern Association for the Surgery of Trauma (EAST) guidelines for cervical spine evaluation after blunt trauma were previously adopted and followed during the study period from December 1, 2002 to July 1, 2003. Our protocol included cross-table lateral and anteroposterior CSR with the occiput-C2 imaged with the head CT. We used segmental cervical spine CT to supplement those regions inadequately visualized by plain films. The electronic charts of 848 consecutive blunt trauma victims were retrospectively reviewed. The data abstracted included demographics, injury severity score, and the use and results of head CT and radiographic evaluation of the cervical spine. RESULTS: Of 848 consecutive blunt trauma patients, 716 (84.4%) underwent head CT. Average age was 44 years old, and average Injury Severity Score was 9. Seventy-six patients (11.6%) had clinical cervical spine examination alone, whereas 640 (89.4%) underwent plain CSR. In 178 patients (27.8%), plain two-view CSR visualized the entire cervical spine. Plain CSR were inadequate to visualize the complete cervical spine in 462 patients (72.2%). Of these patients, segmental CT was performed in 400 (87.6%). The remaining 62 (13.4%) patients did not have radiologic completion of their cervical spine evaluation before clinical examination. Nineteen patients (3.0%) had cervical spine fractures diagnosed on CT, of which only 6 (31.6%) were seen on plain CSR. The sensitivity and specificity of CSR to detect fractures was 31.6 and 99.2%, respectively. CONCLUSION: Plain CSR are inadequate to fully evaluate the cervical spine after blunt trauma, and supplemental CT is commonly required. Complete cervical spine CT is available, efficient, and accurate. Our findings support a growing body of literature that suggests that this modality should be used for blunt trauma patients who require radiographic evaluation of the cervical spine. Plain cervical spine radiographs need not be obtained. The EAST guidelines for cervical spine evaluation after blunt trauma should be updated to reflect this evolving practice pattern.

Respiratory complications and mortality risk associated with thoracic spine injury.
BACKGROUND: Cervical spinal cord injury (SCI) has a well-established association with a high risk of respiratory complications. We sought to determine whether high-thoracic (HT) SCI was associated with a similar increased risk of respiratory complications and death. METHODS: This was a retrospective cohort study of all adult patients with thoracolumbar injuries entered into the Pennsylvania Trauma System Foundation registry between January 1993 and December 2002. Records were reviewed for the documentation of respiratory complications (intubation, tracheostomy, bronchoscopy, pneumonia) and mortality. The data were then evaluated controlling for age, sex, Glasgow Coma Scale, and Injury Severity Score. RESULTS: In all, 11,080 patients met inclusion criteria: 4,258 patients had thoracic spine fractures and 6,226 patients had lumbar spine fractures, all without SCI; and 596 patients had thoracic SCI (T1 to T6, 231; T7 to T12, 365). Respiratory complications occurred in 51.1% of patients with T1 to T6 SCI (versus 34.5% in T7 to T12 SCI and 27.5% in thoracic fractures). The need for intubation, the risk of pneumonia, and risk of death were significantly greater for patients with T1- to T6-level spinal cord injuries. Among patients with an Injury Severity Score less than 17 (n = 6427), the relative mortality risk was 26.7 times higher among those who developed respiratory complications (9.9% versus 0.4%). CONCLUSION: Compared with patients with low thoracic SCI or thoracolumbar fractures, patients with HT-SCI have an increased risk of pneumonia and death. Respiratory complications significantly increase the mortality risk in less severely injured patients. The current findings suggest that HT-SCI patients warrant intensive monitoring and aggressive pulmonary care and attention, similar to that given for patients with cervical SCI.

Management of penetrating colon and rectal injuries in the pediatric patient.
PURPOSE: Management of civilian penetrating colon injuries in the adult has evolved from the universal use of fecal diversion to the highly selective use of colostomy. We hypothesized that a similar management approach was appropriate for the pediatric population. METHODS: A retrospective review of pediatric patients (age <17 years) with a penetrating colorectal injury was performed at six Level I trauma centers for the period January 1990 through June 2001. RESULTS: For the period of review, 53 children with a penetrating colorectal injury were identified. Firearms caused 89 percent of the injuries. The colon was injured in 83 percent (n = 44) of patients and the rectum in 17 percent (n = 9) of patients. The colorectal injury was managed without colostomy in 62 percent (n = 33) and with colostomy in 38 percent (colon = 11, rectum = 9). All rectal injuries were treated with colostomy. The hospital length of stay was longer in the colostomy group (17.6 days vs. 11.4 days). The complication rate was higher in the colostomy group (55 percent vs. 27 percent), which included two patients with stoma-related complications. There was no mortality in this series. CONCLUSIONS: Primary repair was used safely in most cases of civilian penetrating colon injuries in the pediatric population. All rectal injuries were treated with colostomy in this series. Fecal diversion was used selectively. Colostomy was performed for selected cases of colon wounds associated with shock, multiple blood transfusions, multiple other injuries, extensive contamination, and high-velocity weapons. In the absence of these associated factors, primary repair appears justified.

Redefining the future of trauma surgery as a comprehensive trauma and emergency general surgery service.
BACKGROUND: Dwindling operative opportunities in trauma care may have a detrimental impact on career satisfaction among trauma surgeons and on career attractiveness to surgical trainees. Addition of emergency general surgery may alleviate some of these concerns. STUDY DESIGN: The trauma service at our institution incorporated nontrauma emergency general surgery over a 3-year period. The institution's trauma registry and hospital perioperative database were queried. The changes in operative caseload are described. Current trauma faculty anonymously completed a Web-based questionnaire about the addition of emergency general surgery to the trauma service. RESULTS: Operations for trauma decreased in 2002 compared with 1999, despite a higher number of penetrating injuries and total trauma contacts. Nontrauma general surgery operations performed by trauma faculty increased in proportion to coverage provided by the trauma service. In 2002, 57% of all cases performed by trauma surgeons were emergency general surgery, which accounted for 32% to 74% of an individual surgeon's caseload. In anonymously completed Web-based questionnaires, current trauma faculty expressed satisfaction with the combined trauma and emergency general surgery model. CONCLUSIONS: The combined trauma and nontrauma surgery service increased operative caseloads and improved satisfaction of trauma surgeons. A comprehensive trauma and emergency general surgery service may be an attractive model for the future of trauma surgery and provide logistical and medical advantages to the emergency general surgery patient population.

Nonoperative management of abdominal gunshot wounds.
Mandatory surgical exploration for gunshot wounds to the abdomen has been a surgical dictum for the greater part of this past century. Although nonoperative management of blunt solid organ injuries and low-energy penetrating injuries such as stab wounds is well established, the same is not true for gunshot wounds. The vast majority of patients who sustain a gunshot injury to the abdomen require immediate laparotomy to control bleeding and contain contamination. Nonoperative treatment of patients with a gunshot injury is gaining acceptance in only a highly selected subset of hemodynamically stable adult patients without peritonitis. Although the physical examination remains the cornerstone in the evaluation of patients with gunshot injury, other techniques such as computed tomography, diagnostic peritoneal lavage, and laparoscopy allow accurate determination of intra-abdominal injury. The ability to exclude internal organ injury nonoperatively avoids the potential complications of unnecessary laparotomy. Clinical data to support selective nonoperative management of certain gunshot injuries to the abdomen are accumulating, but the approach has risks and requires careful collaborative management by emergency physicians and surgeons experienced in the care of penetrating injury.

Trauma system development in North America.
The concepts of organized trauma care, many of which originated in military medicine, have been proven effective in the civilian sector. A formal trauma system includes all phases of care from prehospital through rehabilitation. Although trauma centers assume the leadership role, in a truly inclusive system, all healthcare providers (prehospital providers, community hospitals, and trauma centers) have a defined role in providing care to patients with trauma. As a result, patients receive treatment at the appropriate institution, resources are allocated appropriately, and the clinical outcome is optimized. Such a system ideally is suited to the unique needs of the mass casualty scenario.
