Applying the antecedent, behaviour, and consequence taxonomy to unintentional firearm injury as determined by a collaborative firearm injury database.

BACKGROUND: Unintentional firearm injury (UFI) remains a significant problem in the USA with respect to preventable injury and death. The antecedent, behaviour and consequence (ABC) taxonomy has been used by law enforcement agencies to evaluate unintentional firearm discharge. Using an adapted ABC taxonomy, we sought to categorise civilian UFI in our community to identify modifiable behaviours. METHODS: Using a collaborative firearm injury database (containing both a university-based level 1 trauma registry and a metropolitan law enforcement database), all UFIs from August 2008 through December 2021 were identified. Perceived threat (antecedent), behaviour and injured party (consequence) were identified for each incident. RESULTS: During the study period, 937 incidents of UFI were identified with 64.2% of incidents occurring during routine firearm tasks. 30.4% of UFI occurred during neglectful firearm behaviour such as inappropriate storage. Most injuries occurred under situations of low perceived threat. UFI involving children was most often due to inappropriate storage of weapons, while cleaning a firearm was the most common behaviour in adults. Overall, 16.5% of UFI involved injury to persons other than the one handling the weapon and approximately 1.3% of UFI resulted in mortality. CONCLUSIONS: The majority of UFI occurred during routine and expected firearm tasks such as firearm cleaning. Prevention programmes should not overlook these modifiable behaviours in an effort to reduce UFIs, complications and deaths.

Patterns of geographic variability in mortality and eligible deaths between organ procurement organizations.

Eligible deaths are currently used as the denominator of the donor conversion ratio to mitigate the effect of varying mortality patterns in the populations served by different organ procurement organizations (OPOs). Eligible death is an OPO-reported metric rather than a product of formal epidemiological analysis, however, and may be confounded with OPO performance. Using Scientific Registry of Transplant Recipients and Centers for Disease Control and Prevention data, patterns of mortality and eligible deaths within each OPO were analyzed with the use of formal geostatistical analysis to determine whether eligible deaths truly reflect the geographic patterns they are intended to mitigate. There was a 2.1-fold difference in mortality between the OPOs with the highest and lowest rates, with significant positive spatial autocorrelation evident in mortality rates (Moran I = .110; P < .001), meaning geographically proximate OPOs tended to have similar mortality rates. The eligible death ratio demonstrated greater variability, with a 4.5-fold difference between the OPOs with the highest and lowest rates. Contrary to the pattern of mortality rates, the geographic distribution of eligible deaths among OPOs was random (Moran I = -.002; P = .410). This finding suggests geographic patterns do not play a significant role in eligible deaths, thus questioning its continuing use in OPO performance comparisons.

Predictors of oliguria in post-traumatic acute kidney injury.

BACKGROUND: Acute kidney injury is classified by urine output into non-oliguric and oliguric variants. Non-oliguric acute kidney injury has lower morbidity and mortality and accounts for up to 64% of acute kidney injury in hospitalized patients. However, the incidence of non-oliguric acute kidney injury in the trauma population and whether the 2 variants of acute kidney injury share the same risk factors is unknown. We hypothesized that oliguria would be present in the majority of acute kidney injury in severely injured trauma patients and that unique risk factors would predispose patients to the development of oliguria. METHODS: Patients admitted to the trauma intensive care unit and diagnosed with an acute kidney injury between 2016 to 2021 were identified. Cases were categorized based on urine output into oliguric (<400 mL per day) and non-oliguric (>400 mL per day) disease. Risk factors, management, and outcomes were compared. Logistic regression was used to identify risk factors associated with oliguria. RESULTS: A total of 227 patients met inclusion criteria. Non-oliguric acute kidney injury accounted for 74% of all cases and was associated with greater survival (78% vs 35.6%, P < .001). Using logistic regression, female sex, vasopressor use, and a greater net fluid balance at 48 hours were all predictive of oliguria (while controlling for age, race, shock index, massive transfusion, operative intervention, cardiac arrest, and nephrotoxic medication exposure). CONCLUSION: Non-oliguria accounts for the majority of post-traumatic acute kidney injury and is associated with improved survival. Specific risk factors for the development of oliguric acute kidney injury include female sex, vasopressor use, and a higher net fluid balance at 48 hours.

Video-assisted thoracoscopy as an important tool for trauma surgeons: a systematic review.

PURPOSE: Trauma patients frequently have serious chest injuries. Retained hemothoraces and persistent pneumothoraces are among the most frequent complications of chest injuries which may lead to major, long-term morbidity and mortality if these complications are not recognized and treated appropriately. Video-assisted thoracoscopy (VATS) is a well-established technique in surgical practice. The usefulness of VATS for treatment of complications after chest trauma has been demonstrated by several authors. However, there is an ongoing debate about the optimal timing of VATS. METHODS: A computerized search was conducted which yielded 450 studies reporting on the use of VATS for thoracic trauma. Eighteen of these studies were deemed relevant for this review. The quality of these studies was assessed using a check-list and the PRISMA guidelines. Outcome parameters were successful evacuation of the retained hemothorax or treatment of other complications as well as reduction of empyema rate, length of hospital stay, and hospital costs. RESULTS: There was only one randomized trial and two prospective studies. Most studies report case series of institutional experiences. VATS was found to be very successful in evacuation of retained hemothoraces and seems to reduce the empyema rate subsequently. Furthermore, the length of hospital stay and costs can be drastically reduced with the early use of VATS. CONCLUSION: Early VATS is an effective treatment for retained hemothoraces or other complications of chest trauma. We propose a clinical pathway, in which VATS is used as an early intervention in order to prevent serious complications such as empyemas or trapped lung.

Traumatic injury may be a predisposing factor for cerebrovascular accident.

The purpose of the study was to assess whether trauma may be an independent risk factor for stroke. Evidence has shown that trauma patients experience a hypercoagulable state postinjury, increasing the risk of thrombotic events. A case-controlled, retrospective analysis was performed on admitted trauma patients over a 2-year period. Results revealed that trauma patients are 1.6 times more likely to have a cerebrovascular accident (CVA) during their hospital admission, when compared with nontrauma patients with similar CVA risk factors. Several statistically significant differences between the groups were identified. On the basis of these results, trauma appears to be an independent, nonmodifiable risk factor for CVA.

A Decade of Analysis of Unplanned Extubation Etiology in Trauma Patients Including the Impact of the COVID Pandemic.

BACKGROUND: Unplanned extubations (UEs) in injured patients are potentially fatal, but etiology and patient characteristics are not well described. We have been prospectively characterizing the etiology of UEs after we identified a high rate of UEs and implemented an educational program to address it. This period of monitoring included the years of the COVID-19 pandemic that produced high rates of workforce turnover in many hospitals, dramatically affecting nursing and respiratory therapy services. We hypothesized that frequency of UEs would depend on the etiology and that the workforce changes produced by the COVID-19 pandemic would increase UEs. METHODS: This study was a prospective tracking and retrospective review of trauma registry and performance improvement data from 2012-2021. RESULTS: UE subjects were younger, were more frequently male, were diagnosed more frequently with pneumonia (38% vs 27%), and had longer hospital (19 d vs 15 d) and ICU length of stay (LOS) (12 d vs 10 d) (all P < .05). Most UEs were due to patient factors (self-extubation) that decreased after education, while UEs from other etiologies (mechanical, provider) were stable. Subjects with UEs from mechanical or provider etiologies had longer ICU LOS, higher mortality, and were less likely to be discharged home. The COVID-19 pandemic was associated with more total patient admissions and more days of ventilator use, but the rate of UEs was not changed. CONCLUSIONS: UEs were decreased by education with ongoing tracking, and UEs from patient factors were associated with better outcome than other etiologies. Workforce changes produced by the COVID-19 pandemic did not change the rate of UEs.

The limitations of hospital and law enforcement databases in characterizing the epidemiology of firearm injury.

BACKGROUND: Current data on the epidemiology of firearm injury in the United States are incomplete. Common sources include hospital, law enforcement, consumer, and public health databases, but each database has limitations that exclude injury subgroups. By integrating hospital (inpatient and outpatient) and law enforcement databases, we hypothesized that a more accurate depiction of the totality of firearm injury in our region could be achieved. METHODS: We constructed a collaborative firearm injury database consisting of all patients admitted as inpatients to the regional level 1 trauma hospital (inpatient registry), patients treated and released from the emergency department (ED), and subjects encountering local law enforcement as a result of firearm injury in Jefferson County, Kentucky. Injuries recorded from January 1, 2016, to December 31, 2020, were analyzed. Outcomes, demographics, and injury detection rates from individual databases were compared with those of the combined collaborative database and compared using χ2 testing across databases. RESULTS: The inpatient registry (n = 1,441) and ED database (n = 1,109) were combined, resulting in 2,550 incidents in the hospital database. The law enforcement database consisted of 2,665 patient incidents, with 2,008 incidents in common with the hospital database and 657 unique incidents. The merged collaborative database consisted of 3,207 incidents. In comparison with the collaborative database, the inpatient, total hospital (inpatient and ED), and law enforcement databases failed to include 55%, 20%, and 17% of all injuries, respectively. The hospital captured nearly 94% of survivors but less than 40% of nonsurvivors. Law enforcement captured 93% of nonsurvivors but missed 20% of survivors. Mortality (11-26%) and injury incidence were markedly different across the databases. DISCUSSION: The utilization of trauma registry or law enforcement databases alone do not accurately reflect the epidemiology of firearm injury and may misrepresent areas in need of greater injury prevention efforts. LEVEL OF EVIDENCE: Epidemiological, level IV.

Early VATS for blunt chest trauma: a management technique underutilized by acute care surgeons.

BACKGROUND: Retained hemothorax and/or empyema is a commonly recognized complication of penetrating chest injuries that may be treated by early video-assisted thoracoscopy (VATS). However, the use of VATS in blunt chest trauma is less well defined. Our acute care surgeon (ACS) group aggressively treats complications of penetrating chest trauma with VATS, and our results suggested that the early use of VATS by ACS should be expanded. MATERIALS: A retrospective review of Trauma Center admissions between January 2007 and December 2009 was performed to identify patients with blunt thoracic injuries who underwent VATS. RESULTS: Eighty-three patients underwent VATS to manage thoracic complications arising from their blunt chest trauma. All operations were performed by ACS. The majority of patients (73%, 61 of 83) were treated with VATS for retained hemothorax, 18% for empyema (15 of 83), and 10% for persistent air leak (8 of 83). All (15) patients who developed empyema had chest tubes placed in the emergency department. No patient treated with VATS for a persistent air leak required further operation or conversion to thoracotomy. VATS performed ≤5 days after injury was associated with a lower conversion to open thoracotomy (8% vs. 29.4%, p < 0.05). Hospital length of stay (LOS) was significantly lower for patients receiving VATS ≤5 days after injury (11 ± 6 vs. 16 ± 8, p < 0.05). No patient treated with VATS ≤5 days had persistent empyema; however, five patients treated with VATS for retained hemothorax or empyema >5 days after injury required further intervention for thoracic infection. Multivariate analysis demonstrated that both a diagnosis of empyema and VATS >5 days after injury were predictors of increased LOS and increased conversion to thoracotomy. CONCLUSIONS: Early VATS can decrease hospital LOS and thoracotomy rate in patient suffering blunt thoracic injuries. ACS can perform this procedure safely and effectively.

Catastrophic gastrointestinal injury due to battery acid ingestion.

BACKGROUND: Acids account for 20% of all chemical exposures through various routes. Caustic acids such as hydrochloric and sulfuric acid are common ingredients in many household and industrial products. Due to the corrosive properties of these substances, tissue injury caused by oral exposure can lead to severe esophageal and gastrointestinal burns. CASE REPORT: We report a case of a patient presenting with severe acidosis, who required multiple laparoscopic evaluations to assess various gastrointestinal tract injuries and who ultimately underwent total gastrectomy. The diagnosis was made primarily based on the arterial blood gas and esophagogastroduodenoscopy findings, as well as the pathological examinations of various biopsied and resected tissues showing hemorrhagic necrosis of the esophagus, stomach, and small bowel. This patient eventually admitted to having ingested an unspecified amount of battery acid. CONCLUSIONS: Collaborative efforts by Emergency Medicine, Pathology, and General Surgery services are required for timely diagnosis, treatment, and management of patients after caustic acid exposures.

A Review of "Prehospital Hypotension as a Valid Indicator of Trauma Team Activation" (2000).

Prehospital hypotension has been utilized for decades as a surrogate marker of injury severity. Several studies have discussed the correlation between injury and hypotension both in the field as well as in the emergency department. Increases have been noted in injury severity score and mortality. Resource utilization is higher in this patient population. This study revisits our original work from 2000 and reviews the current literature regarding hypotension and injury severity. We also examine the role of prehospital hypotension as an indicator of trauma team activation and resource allocation. This review serves as a part of a Literary Festschrift in honor of Dr J David Richardson's role as the Editor-in-Chief of The American Surgeon.

Optimization of donor management goals yields increased organ use.

Multiple strategies have been used in an effort to increase the pool of organs for transplantation. Standardizing donor management has produced promising results. Donor management goals (DMGs) are now being used as end points of intensive care unit care during the prerecovery phase but no prospective results have been reported. Data from the United Network for Organ Sharing Region 11 were collected for successful achievement of eight common donor management goals (mean airway pressure [MAP], central venous pressure [CVP], pH, PaO2, sodium, glucose, single pressor use, and urine output) before organ recovery. Two time periods were studied with different panels of DMGs. The analysis identified the success rate of transplantation. Goals were stratified by their statistical correlation with the number of organs transplanted per donor (OTPD) in an effort to identify the most important parameter(s). Eight hundred five organ donors were studied with 2685 organs transplanted. DMGs were assessed through two phases of the study. Achieving DMGs rose from 18 to 66 per cent associated with significant improvement in OTPD (range, 2.96 to 3.45). The success of transplantation was primarily associated with limitations in vasopressor use and PaO2. Tight glucose control did affect the rate of pancreatic transplants. Thoracic organs were the most sensitive to DMGs with a 10- to 15-fold increase in lung transplantation when PaO2 rose above 100 mmHg. MAP, CVP, pH, sodium, and urine output had little effect on transplantation. Standardization of end points of donor management was associated with increased rates of transplantation. Surprisingly, not all standard goals are necessary for optimal organ use. The most significant parameters were the low use of vasopressor agents and oxygenation. Donor management strategies should strive to optimize these goals.

Decreasing regional neurosurgical workforce-a blueprint for disaster.

BACKGROUND: Traumatic brain injuries are a frequent cause of death and a substantial source of morbidity. Neurosurgeons (NS) are commonly involved in the management of patients with moderate and severe traumatic brain injuries to minimize morbidity from both primary and secondary brain injuries. However, NS willing to care for injured patients have become increasingly scarce. Although many institutions have been individually affected by shortages of NS providing care to injured patients, data on regional changes in NS availability and the effect on patient care are limited. METHODS: We queried a state discharge database for all traumatic intracranial hemorrhages (ICH) and skull fractures from 2004 to 2007 by International Classification of Diseases-9th Rev.-Clinical Modification codes. Institutions were categorized as those that admitted >30 or <30 ICH patients per year. The state medical society provided the number of NS practicing in the state per year. RESULTS: The total number of patients with significant head injuries increased over the study period. The number of NS decreased over the same time period. A greater proportion of patients were managed in centers admitting >30 ICH per year, and the number of facilities admitting <30 ICH per year decreased. CONCLUSION: In this state, increasing numbers of patients with ICH are being concentrated in a small number of centers, while the number of NS available to care for them has decreased. Shortages in neurosurgical workforce for patients with traumatic ICH have the potential for catastrophic consequences on a regional basis if effective solutions to this manpower issue are not created.

Recidivism rates following firearm injury as determined by a collaborative hospital and law enforcement database.

BACKGROUND: Recidivism is a key outcome measure for injury prevention programs. Firearm injury recidivism rates are difficult to determine because of poor longitudinal follow-up and incomplete, disparate databases. Reported recidivism rates from trauma registries are 2% to 3%. We created a collaborative database merging law enforcement, emergency department, and inpatient trauma registry data to more accurately determine rates of recidivism in patients presenting to our trauma center following firearm injury. METHODS: A collaborative database for Jefferson County, Kentucky, was constructed to include violent firearm injuries encountered by the trauma center or law enforcement from 2008 to 2019. Iterative deterministic data linkage was used to create the database and eliminate redundancies. From patients with at least one hospital encounter, raw recidivism rates were calculated by dividing the number of patients injured at least twice by the total number of patients. Cox proportional hazard models were used to evaluate risk factors for recidivism. The cumulative incidence of recidivism over time was estimated using a Kaplan-Meier survival model. RESULTS: There were 2, 363 assault-type firearm injuries with at least 1 hospital encounter, approximately 9% of which did not survive their initial encounter. The collaborative database demonstrated raw recidivism rates for assault-type firearm injuries of 9.5% compared with 2.5% from the trauma registry alone. Risk factors were young age, male sex, and African American race. The predicted incidence of recidivism was 3.6%, 5.6%, 11.4%, and 15.8% at 1, 2, 5, and 10 years, respectively. CONCLUSION: Both hospital and law enforcement data are critical for determining reinjury rates in patients treated at trauma centers. Recidivism rates following violent firearm injury are four times higher using a collaborative database compared with the inpatient trauma registry alone. Predicted incidence of recidivism at 10 years was at least 16% for all patients, with high-risk subgroups experiencing rates as high as 26%. LEVEL OF EVIDENCE: Epidemiological, level III.

Impact of hollow viscus injuries on outcome of abdominal gunshot wounds.

Abdominal gunshot wounds (GSW) are a source of morbidity and mortality. Limited data are available on the effect of hollow viscus injuries (HVI) secondary to gunshot wounds. GSW sustained in the Louisville area from 2004 to 2007 were reviewed. Attention was given to the impact of HVI from abdominal GSW. Statistical significance was determined. One-hundred ten patients sustained GSW with peritoneal violation. Eighty-six had HVI. Eighteen died after laparotomy with 15 having an HVI. Patients undergoing damage control (DC) have a significant increase in mortality compared with those not requiring DC. Exsanguination was the major cause of mortality (67%). Mortality directly related to HVI was found in 11 per cent. Twenty patients underwent DC with 11 deaths. Isolated HVI did not show a significantly increased mortality compared with other injury patterns involving solid organ or major vascular structures. Various methods of repair showed no significant survival advantage. Recognition and repair of HVI in abdominal GSW is crucial to patient salvage. Definitive repair of HVI at the initial operation should be considered. Primary repair of HVI is preferred although no survival disadvantage is seen in other forms of repair in marginally stable patients. Definitive repair at the initial operation decreases complications.

Incremental increases in organ retrieval after protocol driven change in an organ procurement organization: a 15-year assessment.

The need for transplantable organs exceeds the available supply. Organ procurement organizations (OPOs) have undergone both voluntary and mandated changes to optimize available organs. The data from a single statewide OPO was reviewed from 1993 to 2008 and tracked with implementation of new protocols. During the study, 5548 organs were recovered with 4875 transplanted from 1441 donors (3.38 organs transplanted/donor (OTPD)). The conversion rate (CR) for consent rose from 42 to 72 per cent whereas the average age of donors increased from 33 to 45 years. After implementation of a family support liaison program, a higher performing hospital in the OPO realized an increase in CR from 57 to 97 per cent over 8 years. Implementation of an intensivist program improved OTPD. The number of standard criteria donors and extended criteria donors (ECD) increased. The increase in standard criteria donors yielded a large number of thoracic organs. ECD increased as did the organ discard rate from 8 to 16 per cent. Increases in organ retrieval were noted after incremental changes in OPO protocol. Family support and intensivist programs enhanced CR and OTPD. Increases in the number of ECD were noted with increasing age after the introduction of the intensivist program and an increase in transplant center use of these organs.

Management differences for pediatric solid organ injuries in a rural state.

Pediatric liver and spleen injuries are frequently treated in specialized hospitals. Not all injured children, however, are treated in referral centers. We evaluated the management of pediatric liver and spleen injuries in a rural state without a state trauma system to determine if differences existed between trauma centers and nontrauma centers. A state database was queried for patients < or = 15-years-old who suffered liver and spleen injuries from 2003 to 2005. Iatrogenic injuries were excluded. There were 115 pediatric liver and 183 pediatric spleen injuries. Fifty per cent of liver and 63 per cent of spleen injuries in nontrauma centers were isolated solid organ injuries compared with 18 per cent and 36 per cent, respectively, in trauma centers. The mortality rate for both liver and spleen injuries was similar in trauma and nontrauma centers. Hospital charges were higher in trauma centers but this was due to patients with associated injuries. The nonoperative management rate was similar for liver injuries. Pediatric patients with splenic injuries had a lower rate of nonoperative management in nontrauma centers (75% to 90%, nontrauma vs trauma). In Kentucky, pediatric solid organ injuries are usually managed nonoperatively in both trauma and nontrauma centers, but trauma centers cared for fewer isolated solid organ injuries.

An analysis of risk-taking behavior among adolescent blunt trauma patients.

INTRODUCTION: The impact of risk-taking behavior among adolescent blunt trauma patients is not fully appreciated. This study examined the relationship between adolescent risk-taking behaviors, the resultant injury severity, and outcome for blunt trauma. METHODS: Between January 2000 and December 2005, data were collected on adolescent blunt trauma patients (12-18 years) admitted to either a Level I adult trauma center or large urban pediatric hospital. Five groups of risk-taking behavior were examined: ATV riders, drug and alcohol users, unhelmeted motorcyclists, unhelmeted extreme sports participants and unrestrained motor vehicle occupants. Demographic data, mechanism of injury, injury severity, hospital course and outcomes were evaluated for each group. RESULTS: A total of 2030 adolescents were admitted following blunt trauma; 723 adolescents (36%) were engaged in risk-taking behavior at the time of their injury. Most patients were male (68%). Unrestrained MVA occupants were the most frequently encountered risk takers (37%); among this subset, most were unrestrained passengers (74%). Head injuries were frequent (22%) among risk takers. When compared to non-risk-takers, there were no significant age, race, gender, or ISS differences. However, a significantly higher number of positive head CT scans were found among risk-taking adolescents (22%, p < 0.05). Mortality was low (3%). CONCLUSIONS: Risk-taking behavior is prevalent among adolescent blunt trauma patients. Improved injury prevention strategies are needed to discourage these behaviors during adolescence.

Operative Management of Thoracic Gunshot Wounds: More Aggressive Treatment Has Been Required over Time.

Our department has a database of thoracic gunshot wounds (GSWs), which has cataloged these injury patterns over the past five decades. Prevailing wisdom on the management of these injuries suggested operative treatment beyond tube thoracostomy is not commonly required. It was our clinical impression that the operative treatment required beyond chest tube placement has greatly increased over the past several decades, whereas the operative management of cardiac GSWs seemed to be increasingly infrequent events. To test these observations, we analyzed the treatment of GSWs to the chest and heart in four distinct time periods, categorized as "historical" (1973-1975 and 1988-1990) and "modern" (2005-2007 and 2015-2017). There was a significant increase in emergent thoracotomy, delayed thoracic operations, overall operative interventions, and pulmonary resections from the historical period to the modern era. There was a decline in cardiac injuries treated, whereas the number of injuries remained constant. Mortality was unchanged between the early and later periods. Operative treatment beyond tube thoracostomy was much more prevalent for noncardiac thoracic GSWs in the past two decades than in the prior decades, whereas the number of cardiac wounds treated decreased by half.

Self-Inflicted Stab Wounds: A Single-Center Experience from 2010 to 2016.

Despite low mortality rates, self-inflicted stab wounds (SISWs) can result in significant morbidity and often reflect underlying substance abuse and mental health disorders. This study aimed to characterize demographics, comorbidities, and outcomes seen in self-inflicted stabbings and compare these metrics to those seen in assault stabbings. A Level I trauma center registry was queried for patients with stab injuries between January 2010 and December 2015. Classification was based on whether injuries were SISWs or the result of assault stab wounds (ASWs). Demographic, injury, and outcome measures were recorded. Differences between genders, ethnicities, individuals with and without psychiatric comorbidities, and SISW and ASW patients were assessed. Within the SIWS cohort, no differences were found when comparing age, gender, or race, including need for operative intervention. However, patients with psychiatric histories were less likely to have a positive toxicology test on arrival than those without psychiatric histories (22% vs. 0%, P = 0.04). When compared with 460 ASW patients, SISW were older (41 vs. 35, P < 0.001), more likely to be white (92% vs. 64%, P < 0.001), more likely to have a psychiatric history (15% vs. 4%, P < 0.001), require operative intervention (65% vs. 50%, P = 0.008), and be discharged to a psychiatric facility (47% vs. 0.2%, P < 0.001). SISW patients have higher rates of psychiatric illness and an increased likelihood to require operative intervention as compared with ASW patients. This population demonstrates an acute need for both inpatient and outpatient psychiatric care with early involvement of multidisciplinary teams for treatment and discharge planning.

Is splenectomy after trauma an endangered species?

Nonoperative management of splenic trauma is now the most common treatment modality for splenic injuries and splenectomy has almost disappeared in some trauma centers. Splenectomy for cancer staging is infrequently performed suggesting that the indications for splenectomy continue to evolve. We evaluated a state database to assess a communitywide experience with splenic surgery. International Classification of Diseases, 9th Revision, Clinical Modification diagnosis codes were used to determine the indication for splenic surgery. Indications for splenic surgery were listed as trauma (injury codes), medical (hematological diseases, neoplasms, or procedures in which the spleen might be removed contiguously like distal pancreatectomy), or incidental (noncontiguous procedures). Splenectomies for medical indications (n = 607, 43%) were more common than splenectomies for trauma (n = 518, 37%) or incidental splenectomies (n = 276, 20%). Splenectomy for medical reasons was associated with hematologic disease in 56 per cent, neoplastic disease in 34 per cent, and other diagnoses in 10 per cent of cases. Incidental splenectomies were most commonly associated with operations on the esophagus/stomach (32%) and colon (30%). Mortality rate and length of stay were greatest for incidental (14.4 +/- 0.9 days, 10.9% mortality) compared with trauma (11.0 +/- 0.5 days, 7.7% mortality) or medical (9.7 +/- 0.4 days, 4.8% mortality) splenectomies (all P < 0.05 versus incidental). Our results suggest that in the era of nonoperative management of splenic injuries, medical indications now represent the most common reason for splenectomy. As laparoscopic techniques for elective splenectomy become more common, the changing indication for splenectomy has important ramifications for surgical education and training.
