Ethnicity/race and service-connected disability disparities in civilian traumatic brain injury mechanism of injury and VHA health services costs in military veterans: Evidence from a Level 1 Trauma Center and VA Medical Center

Introduction

The objective of this study was to examine the association of military veteran socio-demographics and service-connected disability with civilian mechanism of traumatic brain injury and long-term Veterans Health Administration (VHA) costs.

Methods

We conducted a 17-year retrospective longitudinal cohort study of veterans with a civilian-related traumatic brain injury from a Level 1 Trauma Center between 1999 and 2013, with VHA follow-up through 2016. We merged trauma center VHA data, and used logit to model mechanism of injury, and generalized linear model to model VHA costs.

Results

African American race or Hispanic ethnicity veterans had a higher unadjusted rate of civilian assault/gun as mechanism of injury (15.38%) relative to non-Hispanic White (7.19%). African American race or Hispanic veterans who were discharged from the trauma center with traumatic brain injury and followed in VHA had more than twice the odds of assault/gun (OR 2.47; 95% CI 1.16:5.26), after adjusting for sex, age, and military service-connected disability. Veterans with service-connected disability ≥50% had more than twice the odds of assault/gun (OR 2.48; 95% CI 0.97:6.31). Assault/gun was associated with significantly higher annual VHA costs post-discharge ($16,807; 95% CI 672:32,941) among non-Hispanic White veterans. Military service-connected disability ≥50% was associated with higher VHA costs among both non-Hispanic White ($44,987; 95% CI $17,159:$72,816) and African American race or Hispanic ($37,901; 95% CI $4,543:$71,258) veterans.

Conclusions

We found that African American race or Hispanic veterans had higher adjusted likelihood of assault/gun mechanism of traumatic brain injury, and non-Hispanic White veterans had higher adjusted annual VHA resource costs associated with assault/gun, post trauma center discharge. Veterans with higher than 50% service-connected disability had higher likelihood of assault/gun and higher adjusted annual VHA resource costs. Assault/gun prevention efforts may be indicated within the VHA, especially in minority and service-connected disability veterans. More data from Level 1 Trauma Centers are needed to assess the generalizability of these findings.

Contribution of age and gender to outcome of blunt splenic injury in adults: multicenter study of the eastern association for the surgery of trauma

BACKGROUND

The purpose of this study was to examine the contribution of age and gender to outcome after treatment of blunt splenic injury in adults.

METHODS

Through the Multi-Institutional Trials Committee of the Eastern Association for the Surgery of Trauma (EAST), 1488 adult patients from 27 trauma centers who suffered blunt splenic injury in 1997 were examined retrospectively.

RESULTS

Fifteen percent of patients were 55 years of age or older. A similar proportion of patients > or = 55 went directly to the operating room compared with patients < 55 (41% vs. 38%) but the mortality for patients > or = 55 was significantly greater than patients < 55 (43% vs. 23%). Patients > or = 55 failed nonoperative management (NOM) more frequently than patients < 55 (19% vs. 10%) and had increased mortality for both successful NOM (8% vs. 4%, p < 0.05) and failed NOM (29% vs. 12%, p = 0.054). There were no differences in immediate operative treatment, successful NOM, and failed NOM between men and women. However, women > or = 55 failed NOM more frequently than women < 55 (20% vs. 7%) and this was associated with increased mortality (36% vs. 5%) (both p < 0.05).

CONCLUSION

Patients > or = 55 had a greater mortality for all forms of treatment of their blunt splenic injury and failed NOM more frequently than patients < 55. Women > or = 55 had significantly greater mortality and failure of NOM than women < 55.

What's a trauma surgeon worth? A salary survey of the Eastern Association for the Surgery of Trauma

BACKGROUND

Professional compensation is an important consideration for all physicians. Few objective data specific to trauma surgery are available to those seeking employment or contract renegotiation in the United States. National benchmark salary data should assist trauma surgeons in securing fair and equitable compensation. The purpose of this study was to survey trauma surgeons who are members of the Eastern Association for the Surgery of Trauma regarding current salary levels, benefits, contract arrangements, practice descriptors, and opinions on professional reimbursement.

METHODS

Anonymous self-report questionnaires were mailed to active members of the Eastern Association for the Surgery of Trauma. Only general surgeons practicing in the United States were included. Data were maintained in a confidential database.

RESULTS

Of 385 surveys mailed, 207 (53.7%) were returned. There were 172 usable questionnaires, for an overall response rate of 44.6%. Nearly 93% of respondents worked in states east of the Mississippi River. Mean age was 42.4 years (range, 33-50 years) and 94.7% were male. Over 66% of the surgeons were fellowship trained in trauma, and 44% were chiefs of trauma services. The mean years of experience was 8.8 years (range, 1-17 years). Most respondents worked at teaching institutions (88%) and Level I centers (66%). The mean annual compensation was $229,142+/-$78,045 (range, $90,000-$528,000). These salaries were comparable to ranges from academic surveys of general surgeons. Few surgeons had professional guidance negotiating their compensation. Survey respondents were aware of few objective data specific to trauma surgery.

CONCLUSION

This preliminary survey provides a unique benchmark for trauma surgeon salaries. Trauma surgeons should benefit from a more informed and structured approach to salary negotiations. Detailed trauma surgeon-specific data obtained periodically are essential to ensuring fair and equitable compensation in this specialty.

Blunt splenic injury in adults: Multi-institutional Study of the Eastern Association for the Surgery of Trauma

BACKGROUND

Nonoperative management of blunt injury to the spleen in adults has been applied with increasing frequency. However, the criteria for nonoperative management are controversial. The purpose of this multi-institutional study was to determine which factors predict successful observation of blunt splenic injury in adults.

METHODS

A total of 1,488 adults (>15 years of age) with blunt splenic injury from 27 trauma centers in 1997 were studied through the Multi-institutional Trials Committee of the Eastern Association for the Surgery of Trauma. Statistical analysis was performed with analysis of variance and extended chi2 test. Data are expressed as mean +/- SD; a value of p < 0.05 was considered significant.

RESULTS

A total of 38.5 % of patients went directly to the operating room (group I); 61.5% of patients were admitted with planned nonoperative management. Of the patients admitted with planned observation, 10.8% failed and required laparotomy; 82.1% of patients with an Injury Severity Score (ISS) < 15 and 46.6% of patients with ISS > 15 were successfully observed. Frequency of immediate operation correlated with American Association for the Surgery of Trauma (AAST) grades of splenic injury: I (23.9%), II (22.4%), III (38.1%), IV (73.7%), and V (94.9%) (p < 0.05). Of patients initially managed nonoperatively, the failure rate increased significantly by AAST grade of splenic injury: I (4.8%), II (9.5%), III (19.6%), IV (33.3%), and V (75.0%) (p < 0.05). A total of 60.9% of the patients failed nonoperative management within 24 hours of admission; 8% failed 9 days or later after injury. Laparotomy was ultimately performed in 19.9% of patients with small hemoperitoneum, 49.4% of patients with moderate hemoperitoneum, and 72.6% of patients with large hemoperitoneum.

CONCLUSION

In this multicenter study, 38.5% of adults with blunt splenic injury went directly to laparotomy. Ultimately, 54.8% of patients were successfully managed nonoperatively; the failure rate of planned observation was 10.8%, with 60.9% of failures occurring in the first 24 hours. Successful nonoperative management was associated with higher blood pressure and hematocrit, and less severe injury based on ISS, Glasgow Coma Scale, grade of splenic injury, and quantity of hemoperitoneum.

Billing, coding, and documentation in the critical care environment

Optimal conduct of modern-day physician practices involves a thorough understanding and application of the principles of documentation, coding, and billing. Physicians' role in these activities can no longer be secondary. Surgeons practicing critical care must be well versed in these concepts and their effective application to ensure that they are competitive in an increasingly difficult and demanding environment. Health care policies and regulations continue to evolve, mandating constant education of practicing physicians and their staffs and surgical residents who also will have to function in this environment. Close, collaborative relationships between physicians and individuals well versed in the concepts of documentation, coding, and billing are indispensable. Similarly, ongoing educational and review processes (whether internal or consultative from outside sources) not only can decrease the possibility of unfavorable outcomes from audit but also will likely enhance practice efficiency and cash flow. A financially viable practice is certainly a prerequisite for a surgical critical care practice to achieve its primary goal of excellence in patient care.

Acinetobacter calcoaceticus pneumonia and the formation of pneumatoceles

Pneumatoceles are cystic lesions of the lungs often seen in children with staphylococcal pneumonia and positive-pressure ventilation. Acinetobacter calcoaceticus is an aerobic, short immobile gram-negative rod, or coccobacillus, which is an omnipresent saprophyte. The variant anitratus is the most clinically significant pathogen in this family, usually presenting as a lower respiratory tract infection. Acinetobacter has been demonstrated to be one of the most common organisms found in the ICU. We present three critically ill surgery patients with Acinetobacter pneumonia, high inspiratory pressures, and the subsequent development of pneumatoceles. One of these patients died from a ruptured pneumatocele, resulting in tension pneumothorax. Treatment of pneumatoceles should center on appropriate intravenous antimicrobial therapy. This should be culture directed but is most often accomplished with Imipenem. Percutaneous, computed tomographic-guided catheter placement or direct tube thoracostomy decompression of the pneumatocele may prevent subsequent rupture and potentially lethal tension pneumothorax.

Diagnosis and management of blunt small bowel injury: a survey of the membership of the American Association for the Surgery of Trauma

BACKGROUND

Blunt small bowel injury (SBI) may be difficult to diagnose accurately. Diagnostic delays are associated with increased morbidity and mortality.

METHODS

A cross-sectional survey of members of the American Association for the Surgery of Trauma was conducted. A Likert-type multiple-choice scale was used to evaluate use and usefulness of diagnostic and laboratory tests. Data were analyzed by using univariate and multivariate techniques.

RESULTS

A total of 461 of the 702 members (68%) surveyed responded, of which 133 members (29%) were excluded because they did not currently manage adult SBI. Of the remaining 328 respondents, 244 members (74%) reported prior experience as the most important influence on their current practice of diagnosing blunt SBI. None of the standard laboratory tests were reported as useful. Seventy-seven percent of respondents use computed tomographic (CT) scan most or all of the time for diagnosis (p < 0.05 compared with other modalities). Most respondents estimated their annual incidence of SBI at 5% with a >15% frequency of delay in diagnosis. Forty-four percent of the respondents estimated the mortality associated with a delay in diagnosis at < or =5%. Respondents varied significantly in their management of the patient with an unreliable abdominal exam and a CT scan finding of isolated free fluid. In patients with head injuries, 28% observe, 12% repeat the CT scan, 42% perform diagnostic peritoneal lavage, and 16% operate. For intoxicated patients, 51% observe, 11% repeat the CT scan, 26% perform diagnostic peritoneal lavage, and 10% operate. A more aggressive approach with diagnostic and operative intervention was significantly (p < 0.05) advocated by respondents practicing without residents, more than 15 years out from residency, or by those with a perception of higher morbidity and mortality from delays in diagnosis.

CONCLUSION

There is significant variation in the diagnostic approach to the patient with suspected SBI. The perceived mortality of delayed diagnosis is much less than reported. Those surgeons with more experience or perception of greater morbidity and mortality from a delayed diagnosis are more aggressive. Further investigation into the diagnosis and treatment of this injury is needed.

Relatively short diagnostic delays (<8 hours) produce morbidity and mortality in blunt small bowel injury: an analysis of time to operative intervention in 198 patients from a multicenter experience

OBJECTIVE

Blunt small bowel injury (SBI) is uncommon, and its timely diagnosis may be difficult. The impact of operative delays on morbidity and mortality has been unclear. The purpose of this study was to determine the relationship of diagnostic delays to morbidity and mortality in blunt SBI.

METHODS

Patients with blunt SBI with perforation were identified from the registries of eight trauma centers (1989-1997). Patients with duodenal injuries were excluded. Data were extracted by individual chart review. Patients were classified as multi-trauma (group 1) or near-isolated SBI (group 2 with Abbreviated Injury Scale score < 2 for other body areas). Time to operation and its impact on mortality and morbidity was determined for each patient.

RESULTS

A total of 198 patients met inclusion criteria: 66.2% were male, mean age was 35.2 years (range, 1-90 years) and mean Injury Severity Score was 16.7 (range, 9-47). 100 patients had multiple injuries (group 1). There were 21 deaths (10.6%) with 9 (4.5%) attributable to delay in operation for SBI. In patients with near-isolated SBI, the incidence of mortality increased with time to operative intervention (within 8 hours: 2%; 8-16 hours: 9.1%; 16-24 hours: 16.7%; greater than 24 hours: 30.8%, p = 0.009) as did the incidence of complications. Delays as short as 8 hours 5 minutes and 11 hours 15 minutes were associated with mortality attributable to SBI. The rates of delay in diagnosis were not significantly associated with age, gender, intoxication, transfer status, or presence of associated injuries.

CONCLUSION

Delays in the diagnosis of SBI are directly responsible for almost half the deaths in this series. Even relatively brief delays (as little as 8 hours) result in morbidity and mortality directly attributable to "missed" SBI. Further investigation into the prompt diagnosis of this injury is needed.

Accuracy of administrative data in trauma

BACKGROUND

Accurate data are needed to evaluate outcomes, therapeutics, and quality of care. This study assesses the accuracy of administrative databases in recording information about trauma patients.

METHODS

Patients with thoracic aorta injury were identified with a state trauma registry, and the medical records were reviewed. Data collected were compared to administrative data on patients with thoracic aorta injuries, at the same hospitals in the same time period.

RESULTS

Fifteen patients (16.3%) with thoracic aorta injury were not recorded in the administrative database, and 23 patients (18.7%) were misdiagnosed. Ninety-one patients were found in both data sources. The administrative database significantly (P < .05) underrecorded abdominal injuries (50 vs 35), orthopedic injuries (117 vs 75), and chest injuries (77 vs 48). The number of aortograms (78 vs 8), type of operative procedures (use of graft; 70 vs 30), use of bypass (35 vs 16), and complications (77 vs 33) were underreported (P < .05). The Injury Severity Score was underestimated by the administrative database (38.65 +/- 12.41 vs 25.66 +/- 9.53; P < .05).

CONCLUSIONS

Administrative data lack accuracy in the recording of associated injury, injury severity, diagnostic, and procedural data. Whether these data should be used to evaluate treatment or quality of care in trauma is questionable.

The utility of traditional prehospital interventions in maintaining thermostasis

OBJECTIVE

Hypothermia can have a negative effect on the metabolic and hemostatic functions of patients with traumatic injuries. Multiple methods of rewarming are currently used in the prehospital arena, but little objective evidence for their effectiveness in this setting exists. The purpose of this study was to assess the relative effectiveness of traditional prehospital measures in maintaining thermostasis in trauma patients.

METHODS

Participating helicopter and ground ambulance ALS units were prospectively randomized to provide either routine care only (passive or no warming) or routine care (passive warming) in conjunction with active warming (either reflective blankets, hot pack rewarming, or warmed IV fluids). A total of 174 trauma code patients, aged >14 years, who met inclusion criteria were prospectively enrolled by prehospital providers. Patients who received a non-assigned intervention or who had incomplete temperature data were dropped from the analysis. A total of 134 patients were included in the final analysis.

RESULTS

Patients who received hot pack rewarming showed a mean increase in body temperature during transport (+1.36 degrees F/0.74 degrees C), while all other groups (no intervention, passive rewarming, reflective blankets, warmed IV fluids, warmed IV fluid plus reflective blanket) showed a mean decrease in temperature during transport [-0.34 to -0.61 degrees F (-0.2 to -0.4 degrees C); p<0.01]. In addition, the hot pack group was consistent, with every patient who received hot pack warming showing an increase in body temperature during transport, while in all other groups there were patients who had both increases and decreases in temperature. The intervention groups did not differ significantly on exposure to precipitation, transport unit temperature, total prehospital time, initial vital signs, amount of fluid administered, Injury Severity Score, or Glasgow Coma Score.

CONCLUSIONS

Most traditional methods of maintaining trauma patient temperature during prehospital transport appear to be inadequate. Aggressive use of hot packs, a simple, inexpensive intervention to maintain thermostasis, deserves further study as a potential basic intervention for trauma patients.

The conundrum of the Glasgow Coma Scale in intubated patients: a linear regression prediction of the Glasgow verbal score from the Glasgow eye and motor scores

BACKGROUND

The Glasgow Coma Scale (GCS), which is the foundation of the Trauma Score, Trauma and Injury Severity Score, and the Acute Physiology and Chronic Health Evaluation scoring systems, requires a verbal response. In some series, up to 50% of injured patients must be excluded from analysis because of lack of a verbal component for the GCS. The present study extends previous work evaluating derivation of the verbal score from the eye and motor components of the GCS.

METHODS

Data were obtained from a state trauma registry for 24,565 unintubated patients. The eye and motor scores were used in a previously published regression model to predict the verbal score: Derived Verbal Score = -0.3756 + Motor Score * (0.5713) + Eye Score * (0.4233). The correlation of the actual and derived verbal and GCS scales were assessed. In addition the ability of the actual and derived GCS to predict patient survival in a logistic regression model were analyzed using the PC SAS system for statistical analysis. The predictive power of the actual and the predicted GCS were compared using the area under the receiver operator characteristic curve and Hosmer-Lemeshow goodness-of-fit testing.

RESULTS

A total of 24,085 patients were available for analysis. The mean actual verbal score was 4.4 +/- 1.3 versus a predicted verbal score of 4.3 +/- 1.2 (r = 0.90, p = 0.0001). The actual GCS was 13.6 + 3.5 versus a predicted GCS of 13.7 +/- 3.4 (r = 0.97, p = 0.0001). The results of the comparison of the prediction of survival in patients based on the actual GCS and the derived GCS show that the mean actual GCS was 13.5 + 3.5 versus 13.7 + 3.4 in the regression predicted model. The area under the receiver operator characteristic curve for predicting survival of the two values was similar at 0.868 for the actual GCS compared with 0.850 for the predicted GCS.

CONCLUSIONS

The previously derived method of calculating the verbal score from the eye and motor scores is an excellent predictor of the actual verbal score. Furthermore, the derived GCS performed better than the actual GCS by several measures. The present study confirms previous work that a very accurate GCS can be derived in the absence of the verbal component.

Immediate endoscopic injection therapy of bleeding oesophageal varices: a prospective comparative evaluation of injecting materials in Egyptian patients with portal hypertension

The present study was conducted to compare usual sclerosants: polidocanol 1%, ethanolamine oleate 5% and the tissue adhesive: cyanoacrylate in the control of oesophageal variceal bleeding in Egyptian patients with portal hypertension in a prospective comparative trial. Sixty patients with portal hypertension due to schistosomal hepatic fibrosis and/or posthepatitic liver cirrhosis who had presented with acute oesophageal variceal bleeding were enrolled. Patients received balloon tamponade prior to injection were excluded. Resuscitation had been done before or during emergency endoscopy. Emergency endoscopy was conducted within 2 hours from the onset of hematemesis. Patients were immediately randomized during emergency endoscopy to receive polidocanol 1%, ethanolamine oleate 5% or tissue adhesive. Variceal rebleeding was managed by reinjection. The three groups were comparable for age, sex, etiology of portal hypertension, Child-Pugh class and findings at emergency endoscopy. No active bleeding was observed at the end of all injection sessions. Rebleeding had been occurred within the first 24 hours in 2 (10%) patients in polidocanol group and 3 (15%) patients in ethanolamine group (P > 0.05). Reinjection did control rebleeding in 2 (10%) patients in ethanolamine group with a total success rate of 95%. Exsanguinating rebleeding occurred in 2 (10%) patients in polidocanol group and one (5%) patient in ethanolamine group (P > 0.05). Postinjection large ulcers were diagnosed either in polidocanol (15%) or ethanolamine (10%) groups (P > 0.05). Other complications were minor and showed no significant differences between the three groups. In coclusion, polidocanol, ethanolamine and cyanoacrylate are equally safe and effective. For immediate endoscopic injection therapy an experienced team must be available.

Statewide, population-based, time-series analysis of the frequency and outcome of pulmonary embolus in 318,554 trauma patients

The low occurrence, nonspecific signs and symptoms, and high rate of associated morbidity and mortality of pulmonary embolus (PE) create major problems in the prevention, diagnosis, and treatment of PE. The purpose of this study was to analyze the frequency and outcome of PE in an entire state's trauma population using a large, population-based, hospital discharge data base. With the inclusion of an entire population, the reported incidence, high risk groups of patients, and specific risk factors regarding PE were assessed. A multivariate, logistic regression model was created from the data to determine predictive power of selected risk factors in patients at risk.

METHODS

The data source was a statewide, hospital discharge data base that includes data on all hospitalized patients for all of the hospitals in North Carolina. Data were available from 1988 to 1993. Using primary discharge diagnosis and nine additional ICD-9 coded diagnoses from the discharge abstract, patients were selected by presence of diagnostic codes for traumatic injury (800-959.9) and PE (415.1). Statistical analysis was performed using univariate and multivariate analysis to determine significant risk factors and to create a candidate model for the prediction of risk in the study population.

RESULTS

Of 318,554 patients, 952 (0.30%) had a recorded diagnosis of PE. The mortality rate for patients with PE (26%) was 10 times higher than the mortality rate in patients without PE (2.6%). In evaluating specific risk factors, age was a significant predictor of the risk of PE: 0.05% for patients under age 55 and 0.7% in those 55 years and over. The rate of PE, 0.3%, was low for the entire study population, but was highest in patients with injuries of the extremities, 0.53%. Increasing Injury Severity Score and Abbreviated Injury Scale score for determined body systems were also found to correlate with an increasing risk of PE. Over the course of the study, the incidence of PE among patients discharged from non-trauma centers showed a significant decrease. There was also a decrease in the mortality in non-trauma centers for PE. This finding cannot be due to coding changes coincident with the advent of diagnosis related groups because it would be associated with more vigorous combing of charts for diagnoses? It may well be that the use of prophylactic measures in injured patients initially used at trauma centers was adopted by the physicians at non-trauma centers over this time with the resultant decline in PE and associated mortality. From the univariate linear regression models, a logistic regression model was created that confirmed age as the most significant risk factor, followed by Injury Severity Score and Abbreviated Injury Scale score for soft tissue, extremity, and chest. The calculated area under the receiver operator characteristic curve was 0.72.

CONCLUSION

Using a large, population-based data base, we were able to determine the reported incidence of PE among trauma patients and establish specific risk factors. The reported incidence of PE in this population is low, 0.30%. The mortality among those with PE, however, is significant at 26%. In this study, age, Injury Severity Score, and injury to specific body regions (soft tissue, extremity, chest) were associated with an increased risk of PE. The investigation of prophylaxis of PE and the general management of injured patients may be influenced by the overall low reported frequency of PE and the specific high risk populations described in this study. In light of the low incidence of PE in patients without specific risk factors, prophylactic interventions cannot be routinely recommended unless their benefits clearly outweigh their risks.

Survival, quality of life, and charges in critically III surgical patients requiring prolonged ICU stays

Critical care consumes a significant portion of health care costs. Although there are currently increasing pressures to limit expenditures, data are not always available to allow physicians and patients to make informed therapeutic or triage decisions regarding prolonged intensive care unit (ICU) stays. The purpose of this study was to evaluate long-term outcome, quality of life, and charges in surgical patients requiring prolonged ICU stays (> 14 days).

METHODS

Adults requiring over 14 days of surgical ICU care from January 1991 to September 1993 were selected from our ICU data base. Survivors to hospital discharge were evaluated for outcome and quality of life by mail survey and/or telephone interview in addition to chart review.

RESULTS

Eighty-three patients spent over 14 days in the surgical ICU during the study period. Fifty-two patients (62.6%) survived to hospital discharge. Average age was 53 years, average ICU length of stay was 26 days, and average hospital length of stay was 50 days. Complete follow-up data were available for 39 patients (75%). Thirty of the 39 patients (77%) were alive at an average follow-up of 18 months. Long-term survival in patients over 65 years old was 67% compared with 83% for younger patients (p < 0.05). Seventy percent reported less than 50% functional recovery. Seventy percent wer living at home and 23% were on disability. Of 11 patients employed before discharge, five had returned to work. Eighty percent of respondents reported good to fair quality of life, and 81% stated that they would undergo critical care again. The average ICU charge was $51,512 per patient, and the average hospital charge was $164,019 per patient. The average charge to achieve one long-term survivor was $247,812.

CONCLUSIONS

In this population, prolonged ICU stays resulted in acceptable quality of life and a relatively high survival rate despite significant economic investment. This study does not support withdrawal of therapy or triage decisions based solely or primarily on age or length of ICU stay.

Management and outcome of splenic injury: the results of a five-year statewide population-based study

Although splenectomy was the preferred method of treating the injured spleen in the past, the methods of splenorrhaphy and nonoperative management have appeared to gain in popularity. The purpose of this study was to determine whether the management of splenic injuries has changed over the course of time and if there has been any differences in the morbidity and mortality associated with different methods of treatment. We retrospectively examined the discharge records from 2627 patients with splenic injuries from the North Carolina Discharge Database. There were 2258 adults and 369 pediatric patients for evaluation. The rate of nonoperative therapy increased from 33.9 per cent to 46.3 per cent over the 5 years of the study, whereas the rate of splenectomy decreased from 52.9 per cent to 43.4 per cent over the same time period. Splenorrhaphy was used in approximately 10 per cent of the injuries over the course of the entire study period. Adults treated nonoperatively required late operation 6.0 per cent (49/811) of the time. The pediatric late operation rate for nonoperative management was 0.4 per cent(1/231). Reoperation after splenorrhaphy was 2.9 per cent (7/240) for adult patients and 4.3 per cent (2/47) for pediatric patients. The majority of adults (57.2%) with an Injury Severity Score (ISS) < or = 15 were able to be cared for via nonoperative methods, whereas the majority of adults (66.4%) with an ISS > 15 required splenectomy. The majority of pediatric patients were able to be cared for in a nonoperative fashion in both the ISS < or = 15 (83.4%) and ISS > 15 (45.5%).

The impact of laparoscopic cholecystectomy on the management and outcome of biliary tract disease in North Carolina: a statewide, population-based, time-series analysis

BACKGROUND

Laparoscopic cholecystectomy (LC) has had a major impact on the treatment of patients with biliary tract disease, but the magnitude and the details of its effects on biliary surgery remain incompletely described. The purpose of this study was to perform a statewide, population-based, time-series analysis of the effects of LC on biliary surgery.

STUDY DESIGN

Patient data were obtained from the statewide hospital discharge database that collects data from all 157 hospitals in the state of North Carolina. All patients with hospital admissions for biliary tract disease from 1988 through 1993 were selected for analysis.

RESULTS

The use of open cholecystectomy (OC) dropped from 100 percent of all cholecystectomies in 1988 to 32.3 percent in 1993, while LC increased from eight cases in 1988 to over 7,800 per year in 1993. The increase in the rate of LC was not associated with an increase in the overall rate of cholecystectomy. Bile duct (BD) repairs increased from 13 in 1988 to a high of 36 in 1992. There was a strong, statistically significant correlation between the rate of LCs and the rate of BD repairs (R = 0.89, p = 0.0001). Hospital charges and component charges were lower for patients having elective LC compared to those having elective OC (p = 0.001). This remained true after stratification by age and type of gallbladder disease. Hospital stays were shorter for patients having LC than for those having OC (p = 0.001 for all). Surgeons in smaller hospitals were slower at adopting LC. Younger and board certified surgeons adopted LC more rapidly than older and non-board certified surgeons.

CONCLUSIONS

In North Carolina, LCs progressed from nonexistent to the dominant approach for managing patients with cholelithiasis in a matter of a few years. Associated with this change were shorter hospitalizations and lower charges. Contrary to other published reports, North Carolina did not experience an increase in the overall rate of cholecystectomy with the adoption of LC. There was a highly correlated increase in the rate of bile duct repairs in the first years of the study.

A statewide, population-based time-series analysis of the increasing frequency of nonoperative management of abdominal solid organ injury

Emergency operative intervention has been one of the cornerstones of the care of the injured patient. Over the past several years, nonoperative management has increasing been recommended for the care of selected blunt abdominal solid organ injuries. The purpose of this study was to utilize a large statewide, population-based data set to perform a time-series analysis of the practice of physicians caring for blunt solid organ injury of the abdomen. The study was designed to assess the changing frequency and the outcomes of operative and nonoperative treatments for blunt hepatic and splenic injuries.

METHODS

Data were obtained from the state hospital discharge data base, which tracks information on all hospitalized patients from each of the 157 hospitals in the state of North Carolina. All trauma patients who had sustained injury to a solid abdominal organ (kidney, liver, or spleen) were selected for initial analysis.

RESULTS

During the 5 years of the study, 210,256 trauma patients were admitted to the state's hospitals (42,051 +/- 7802 per year). The frequency of nonoperative interventions for hepatic and splenic injuries increased over the period studied. The frequency of nonoperative management of hepatic injuries increased from 55% in 1988 to 79% in 1992 in patients with hepatic injuries and from 34% to 46% in patients with splenic injuries. The rate of nonoperative management of hepatic injuries increased from 54% to 64% in nontrauma centers compared with an increase from 56% to 74% in trauma centers (p = 0.01). In patients with splenic injuries, the rate of nonoperative management increased from 35% to 44% in nontrauma centers compared with an increase from 33% to 49% in trauma centers (p < 0.05). The rate of nonoperative management was associated with the organ injury severity, ranging from 90% for minor injuries to 19%-40% for severe injuries. Finally, in an attempt to compare blood use in operatively and nonoperatively treated patients, the total charges for blood were compared in the two groups. When compared, based on organ injury severity, the total blood used, as measured by charges, was lower for nonoperatively treated patients.

CONCLUSIONS

This large, statewide, population-based time-series analysis shows that the management of blunt injury of solid abdominal organs has changed over time. The incidence of nonoperative management for both hepatic and splenic injuries has increased. The study indicates that the rates of nonoperative management vary in relation to the severity of the organ injury. The rates increase in nonoperative management were greater in trauma centers than in nontrauma centers. These findings are consistent with the hypothesis that this newer approach to the care of blunt injury of solid abdominal organs is being led by the state's trauma centers.

Prospective analysis of outcome after cardiopulmonary resuscitation in critically ill surgical patients

BACKGROUND

This study was done to examine the outcome of cardiopulmonary resuscitation (CPR) in the surgical intensive care unit (SICU) and to identify factors preceding cardiopulmonary arrest that could predict survival.

STUDY DESIGN

We prospectively collected demographic, laboratory, diagnostic, and complications data in our SICU database on 5,237 consecutive patients and reviewed the charts of all patients receiving CPR.

RESULTS

Cardiopulmonary resuscitation was performed upon 1.1 percent (55 of 5,237 patients) of patients in the SICU. Twenty-nine percent (16 of 55 patients) survived greater than 24 hours but died in the hospital, and 13 percent (seven of 55 patients) survived to discharge. No patient with a worsening Glasgow Coma Scale (GCS) score, acute physiology score (APS), or any acute organ failure who had cardiopulmonary arrest survived. Survival after CPR for patients with a stable or improving APS was 32 percent (p < 0.01).

CONCLUSIONS

Patients in the SICU who survived CPR had a stable or improving clinical course as determined by APS and GCS score, and had not had acute organ failure. Patients who were critically ill with a declining clinical course did not survive after CPR.

Regional and institutional variation in burn care

In reviewing the literature on burn therapy and observing clinical burn care, we noted differences among institutions and individual experts in several areas. To study variation in burn care, we surveyed the 140 burn centers listed by the American Burn Association to determine how burn care is currently administered in the United States and Canada. Responses were obtained from 83 hospitals (60%). The survey addressed resuscitation, operative and nonoperative wound care, medications, antimicrobial agents, and pain control. The major influence on care appeared to be the experience of the director (considered "very influential" in 85%) compared with the literature ("very influential" in 12%) and habit/what works for us ("very influential" in 48%). The Parkland formula was used "always" or "often" by 78%, and the Brooke formula "never" by 81% of respondents. Lactated Ringer's solution was the most popular initial fluid, and most (78%) respondents changed fluids after 24 hours. However, the fluids used in the second 24 hours varied equally among several choices. The use of colloids also varied without a set pattern. Furosemide (Lasix) and nonsteroidal antiinflammatory drugs were used "rarely" or "never" by 67% of centers in the acute stage. H2 blockers were used for gastritis prophylaxis "always" or "often" in 60% (vs 53% for antacids and 20% for sucralfate [Carafate]). Tube feedings were started on day 1 after burn injury "always" by less than 30% of centers. Total parenteral nutrition was not commonly used. Most centers use of silver sulfadiazine on the body and hands, but facial topical antimicrobial therapy varied.(ABSTRACT TRUNCATED AT 250 WORDS)

Effect of inhalation injury, burn size, and age on mortality: a study of 1447 consecutive burn patients

The relative impact of inhalation injury, burn size, and age on overall outcome following burn injury was examined in 1447 consecutive burn patients over a five and a half year period. The overall mortality for all patients was 9.5% (138 of 1447). The presence of inhalation injury, increasing burn size, and advancing age were all associated with an increased mortality (p < 0.01). The incidence of inhalation injury was 19.6% (284 of 1447) and correlated with increasing percent total body surface area (%TBSA) burn (r = 0.41, p < 0.01) and advancing age (r = 0.15, p < 0.01). The overall mortality for patients with inhalation injury was 31% (88 of 284) compared with 4.3% (50 of 1163) for those without inhalation injury. Using multivariate analysis inhalation injury was found to be an important variable in determining outcome, but the most important factor in predicting mortality was %TBSA burn (accuracy = 92.8%) or a combination of %TBSA burn and patient age (accuracy = 93.0%). Adding inhalation injury only slightly improved the ability to predict mortality (accuracy = 93.3%). The presence of inhalation injury is significantly associated with mortality after thermal injury but adds little to the prediction of mortality using %TBSA and age alone.

Incidence, management, and outcome of femoral shaft fracture: a statewide population-based analysis of 2805 adult patients in a rural state

Early surgical management of femoral shaft fracture (FSF) is considered the standard but patients are still treated nonsurgically. The purpose of this study was to analyze the results of management of FSF in a large population based data base.

METHODS

Data were obtained from a statewide hospital discharge data base for 1989-1992. Adults having a FSF were stratified by ISS (ISS < 15 vs. ISS > or = 15) and management (nonsurgical, surgery within 1 day, surgery at 2-4 days, or surgery at > 4 days). Mortality rates and mean length of hospital stay were compared among groups.

RESULTS

2805 patients had FSFs: 69% were managed surgically and 31% nonsurgically. Mortality was higher for nonsurgical therapy in both ISS groups. In the surgically treated groups, length of hospitalization increased as delay to surgery increased. In patients with an ISS > or = 15, repair at 2-4 days was associated with the lowest mortality and shortest hospitalization, while a trend to higher mortality and longer hospitalization was noted with repair within 1 day.

CONCLUSION

31% of patients were treated nonsurgically with higher associated mortality. These results support "early" surgical fixation, which can shorten hospital stay without increasing mortality regardless of overall injury severity. The trend toward higher mortality in severely injured patients operated on within 1 day of admission suggests that this group warrants further study and individualized management.

A population-based study of the association of medical manpower with county trauma death rates in the United States

OBJECTIVE

To determine the association between measures of medical manpower available to treat trauma patients and county trauma death rates in the United States. The primary hypothesis was that greater availability of medical manpower to treat trauma injury would be associated with lower trauma death rates.

SUMMARY BACKGROUND DATA

When viewed from the standpoint of the number of productive years of life lost, trauma has a greater effect on health care and lost productivity in the United States than any disease. Allocation of health care manpower to treat injuries seems logical, but studies have not been done to determine its efficacy. The effect of medical manpower and hospital resource allocation on the outcome of injury in the United States has not been fully explored or adequately evaluated.

METHODS

Data on trauma deaths in the United States were obtained from the National Center for Health Statistics. Data on the number of surgeons and emergency medicine physicians were obtained from the American Hospital Association and the American Medical Association. Data on physicians who have participated in the American College of Surgeons (ACS) Advanced Trauma Life Support Course (ATLS) were obtained from the ACS. Membership information for the American Association for Surgery of Trauma (AAST) was obtained from that organization. Demographic data were obtained from the United States Census Bureau. Multivariate stepwise linear regression and cluster analysis were used to model the county trauma death rates in the United States. The Statistical Analysis System (Cary, NC) for statistical analysis was used.

RESULTS

Bivariate and multivariate analyses showed that a variety of medical manpower measures and demographic factors were associated with county trauma death rates in the United States. As in other studies, measures of low population density and high levels of poverty were found to be strongly associated with increased trauma death rates. After accounting for these variables, using multivariate analysis and cluster analysis, an increase in the following medical manpower measures were associated with decreased county trauma death rates: number of board-certified general surgeons, number of board-certified emergency medicine physicians, number of AAST members, and number of ATLS-trained physicians.

CONCLUSIONS

This study confirms previous work that showed a strong relation among measures of poverty, rural setting, and increased county trauma death rates. It also found that counties with more board-certified surgeons per capita and with more surgeons with an increased interest (AAST membership) or increased training (ATLS) in trauma care have lower per-capita trauma death rates.(ABSTRACT TRUNCATED AT 400 WORDS)

Report on the clinical workstation and clinical data repository utilization at UNC Hospitals

On December 1, 1993, we implemented version 2.1 of the Clinical Workstation-Clinical Data Repository application in the Ambulatory Care Center. This version of the workstation allowed access of laboratory data from the clinical data repository that had been populated by a real-time HL7 interface between the Clinical Data Repository and the Laboratory Information System. This implementation completed a major part of the Clinical Workstation project. Also in December, we implemented a security system that records the date and time, user logon code, clinical workstation functions used, and the patient medical record number on whom data were displayed. In addition to the security function, this system has proven to be a valuable tool in evaluating the utilization of the clinical workstation and is the source of the data presented in this paper.

An analysis of the association of trauma centers with per capita hospitalizations and death rates from injury

OBJECTIVE

This study used population-based data bases to assess the association of trauma centers with per capita county hospitalization and trauma death rates in the State of North Carolina.

SUMMARY BACKGROUND DATA

The current study extended previous work using two North Carolina data bases to assess the association of the presence of a trauma center with per capita county trauma death rates.

METHODS

Data on per capita county trauma hospitalizations and deaths were obtained from the state hospital discharge data base and the North Carolina Medical Examiner's data base. Bivariate and multivariate analysis techniques were used. The dependent variables of interest were prehospital, hospital, and total trauma death rates and hospitalization rates for injury.

RESULTS

Bivariate analysis identified a number of factors associated with per capita county hospitalizations and trauma death rates. These included the per cent unemployment, racial distribution, county alcohol tax receipts, and advanced life support certified emergency medical services providers. The per capita trauma death rates were significantly lower in counties with trauma centers compared with those without trauma centers (4.0 +/- 0.5 and 5.0 +/- 1.1 deaths per 10,000 population, p = 0.0001, respectively). The per capita hospitalizations for trauma were also lower in counties with trauma centers. Multivariate modeling showed that the presence of a trauma center and advanced life support providers were the best predictors of decreased per capita county trauma death rates.

CONCLUSIONS

The study showed that the presence of a trauma center and advanced life support training were the two medical system factors that were the best predictors of the per capita county prehospital and total trauma death rates. These findings are consistent with the hypothesis that trauma centers are associated with a decrease in trauma death rates.

Progress report on the clinical workstation and clinical data repository at UNC Hospitals

In 1991, we demonstrated a prototype version of the Clinical Workstation at SCAMC. At the present time 48 workstations have been implemented in the ambulatory care areas of the Hospital. We describe the present functionality of the workstation and the work done to date on the clinical data repository.

Acute Physiology and Chronic Health Evaluation (APACHE II) score and outcome in the surgical intensive care unit: an analysis of multiple intervention and outcome variables in 1,238 patients

OBJECTIVE

To assess the statistical association of the Acute Physiology and Chronic Health Evaluation (APACHE II) score with multiple intervention and outcome variables in surgical ICU patients.

DESIGN

Continuous data collection on every patient admitted to the surgical ICU for a 21-month period.

MATERIALS AND METHODS

For every admitted patient in the surgical ICU, APACHE II scores were calculated and the relationship between APACHE II score as an independent predictor of outcome was assessed with multiple outcome variables selected for study. The outcome and intervention variables tested included: treatment intervention measures such as days on ventilator; days with an arterial catheter, central venous catheter, triple lumen catheter, pulmonary artery catheter; days receiving total parenteral nutrition; days receiving tube feedings; number of transducers per days in the ICU; number of infusion pumps per ICU days, days in the hospital, number of complete blood counts; number of electrolyte determinations; number of blood gases; number of units of blood transfused; ICU and hospital mortality rates in the presence of complications, including: respiratory distress syndrome, renal failure, congestive heart failure, coma, requirement of cardiopulmonary resuscitation, and others.

RESULTS

The APACHE II score was statistically associated with each intervention and outcome variable tested. Unfortunately, the associations, although consistent, were weak with r2 values ranging from .03 to a maximum of .22 for Pearson's correlation coefficients.

CONCLUSION

The APACHE II score was statistically associated with all the variables examined in our surgical patients, but its predictive power for the individual surgical patient was limited. These findings suggest that the score may be useful for retrospective analyses of large cohorts of patients but should not be used as a triage tool or as a predictor of outcome for the individual patient. Triage decisions should continue to be based on the best available clinical judgment.

A comparison of intensive care unit care of surgical patients in teaching and nonteaching hospitals

Three hundred forty-eight teaching (TH) and 282 nonteaching (NTH) hospitals were surveyed to determine how intensive care unit (ICU) care is delivered to surgical patients and current views on surgical critical care. Teaching hospitals were more likely than NTHs to have a separate surgical ICU (92% versus 37%), a dedicated ICU service/physician (37% versus 7%), and a surgeon as director of the ICU (67% versus 29%). All THs and 33% of NTHs provided 24 hour in-house coverage for the ICU. A majority of respondents preferred a surgeon as ICU director (TH, 85%; NTH, 67%) and felt that critical care was an essential part of surgery (THs, 87%; NTHs, 74%). Most (THs, 58%; NTHs, 56%) thought that a cooperative effort between the primary service and an ICU service provided better patient care, but only 37% of THs and 22% of NTHs provided care with such a system. Many (THs, 45%; NTHs, 33%) thought that surgeons are willingly relinquishing ICU care. Surgeons continue to desire responsibility for their patients in the ICU and most prefer ICU service involvement provided by surgeons. This discrepancy between what is practiced and what is desired, along with proposed changes in reimbursement for surgery and the recent definition of critical care as an essential part of surgery, may stimulate greater involvement of surgeons in critical care.

Observations and current operative management of congenital lumbar hernias during infancy

Congenital hernias in the lumbar region are very uncommon. Approximately 10 per cent of all lumbar hernias are congenital and the vast majority are unilateral. We report our experience with seven congenital lumbar hernias in six infants treated during a five year period. All patients presented in the first year of life with abnormal protrusions in the lumbar region. In addition to the lumbar hernia, major associated malformations, including caudal regression anomalies, diaphragmatic hernia, ureteropelvic junction obstruction, cloacal exstrophy and lipomeningocele, were observed in 66 per cent of the infants and were consistent with lumbocostovertebral syndrome. In five patients, unilateral defects were repaired primarily. One patient with bilateral lumbar hernia underwent staged repair. The larger right-sided defect was repaired using a polytetrafluoroethylene prosthesis. At a second operation two months later, the small left-sided hernia was closed primarily. All patients have done well without recurrence with a follow-up period ranging from four to 48 months. Early repair of congenital lumbar hernias in infants after correction of other life-threatening conditions is advocated. Unlike the acquired variety, congenital lumbar hernia may include a more extensive deficiency of the entire lateral abdominal wall extending to the rectus sheath and inguinal ligament and satisfactory closure of the defect without prosthetic material may be difficult or impossible.

Cost-effective use of microcomputers for quality assurance and resource utilization in the surgical intensive care unit

Need for organ system support, severity of illness, and the risk of life-threatening complications are major factors in determining the need for ICU care and directly affect ICU costs. Using a microcomputer and a relational database program, an ICU database was developed to study ICU utilization. The following information was collected for each ICU patient on admission, then daily, and on ICU discharge: demographic data, procedures, monitors used, laboratory tests, complications, outcome, and Acute Physiology and Chronic Health Evaluation (APACHE II) score as a measure of acuity. In our study, this information was used as a first step in an attempt to define categories of patients who might benefit most from intensive care and those who would not. From September 1, 1987 to March 1, 1989, 1,062 patients were admitted to the surgical ICU (SICU). Otorhinolaryngology (ENT) patients with major head and neck resections, routinely admitted to the SICU, were compared with those from other surgical services. The ENT patients had the lowest mean admission APACHE II (6.8 +/- 0.4 vs. 11.4 +/- 0.3), lowest mean daily APACHE II (7.8 +/- 0.4 vs. 13.2 +/- 0.1), lowest percent of ventilated patients (7.6% vs. 39.4%) and ventilator days (18.9% vs. 64.6%), and had the least monitoring by central venous catheters (20.9% vs. 57.1%) or pulmonary artery catheters (0.9% vs. 29.8%) (p less than .0001 for all of above). They also had the shortest mean ICU stay (1.2 +/- 0.1 vs. 3.3 +/- 0.2 days, p less than .05). The only complication in 105 ENT patients was one uncomplicated myocardial infarction.(ABSTRACT TRUNCATED AT 250 WORDS)

Critical care education in general surgery residencies

Surgical critical care (SCC) was recently identified as an essential component of general surgery by the American Board of Surgery (ABS). Previous studies have found limited attention to critical care education in general surgery programs. This survey was developed to determine the changes in critical care education, following the emphasis by the ABS. The survey determined the format for SCC education, the time and resources committed, and the views of the program directors toward SCC. Program directors of all 296 approved general surgery residencies were surveyed, with a 79% response. Most program directors (91%) agree that SCC is an essential component of general surgery, and 72% believe a separate intensive care unit (ICU) rotation should be used in SCC education. Education in SCC was provided by a separate ICU service in 110 (47%) of the programs. The remaining 53% used care of patients in the ICU during traditional services as their educational experience. The average ICU rotation for surgery residents was 9 weeks and usually occurred in the second year of training. In 97% of the 110 programs with an ICU service, lectures and conferences were conducted regularly. Seventeen programs sponsored critical care fellowships, and 25 additional programs were considering them. Ninety percent of surgical ICU services had faculty that consisted exclusively of surgeons or surgeons and other specialists. Only 53% of surgeons attending on an ICU service had a reduction in their other responsibilities. Despite overwhelming agreement that critical care is an essential component of general surgery, less than half of the training programs have an ICU service to coordinate resident education in SCC. If surgeons are to continue to provide total care to their patients, there needs to be increased commitment to SCC education.

Cervical vessel injury after blunt trauma

Blunt trauma accounts for 3% to 10% of cervical vessel injuries. Death and severe neurologic impairment have been reported in more than 80% of blunt carotid injuries. In our recent experience, 10 patients sustained 18 blunt cervical arterial injuries: two internal carotid artery (ICA) dissections, three ICA transections with pseudoaneurysm, five ICA thromboses, two vertebral artery dissections, one vertebral artery transection with pseudoaneurysm, one vertebral artery thrombosis, one minimal vertebral artery injury, and three caroticocavernous fistulas. A delay of more than 12 hours in making the diagnosis occurred in seven of the 10 patients. The mental status was initially normal in seven patients. The subsequent development of focal neurologic findings incongruent with CT scanning of the head prompted four-vessel angiography. Treatment was individualized and included supportive management, intravenous heparin, ligation, extracranial-intracranial bypass, and radiologic embolization. We have developed an angiographic classification that may aid management. Early angiography in patients with neurologic findings incongruent with head CT scan or in whom a normal sensorium and hemiparesis are present may permit improved outcomes. We advocate direct operative repair for accessible lesions of recent onset. For surgically inaccessible lesions, those with delayed presentation or in some cases with a fixed neurologic deficit, intravenous heparin can be started and follow-up angiography, head CT scanning, and the patient's clinical status determine further therapy.

Cholecystectomy in morbidly obese patients

Indications for performing cholecystectomy simultaneously with a gastric bariatric operation remain controversial. The extremes are to always perform cholecystectomy or to perform cholecystectomy only when there are palpable stones or the gallbladder is grossly diseased. Since 1975, 136 cholecystectomies have been performed simultaneously in 724 patients who had a gastric bariatric operation. Cholecystectomy had been performed before the bariatric operation in 120 and was required later in 18 patients. The clinical records, anesthesia, pathology, and operative reports provide the data for this study. Simultaneous cholecystectomy was done through the vertical midline incision used for gastric bariatric operation. No patients had the gallbladder bed closed or were drained. Operative cholangiogram were not performed because this procedure would have been difficult and significantly prolonged because of the obesity. No patients have developed postoperative choledocholithiasis. One patient developed a complication related to cholecystectomy, a common bile duct stricture. The length of the operation and the postoperative hospitalization with and without simultaneous cholecystectomy were compared. The results of intraoperative ultrasound studies performed upon these patients are described and discussed. It is concluded that cholecystectomy should be performed simultaneously with all gastric bariatric operations when there is gross or echogenic evidence of gallbladder disease. Cholecystectomy does not significantly prolong or complicate the gastric bariatric operation.

Pseudotumor of the supraclavicular fossa

Minor musculoskeletal variants of the upper thoracic spine or of the ribs can cause effacement of the supraclavicular fossa, simulating a mass ("pseudotumor"). These variants may occur singly or in combination, and include unilateral prominence or asymmetry of the first rib, unilateral prominence or asymmetry of a cervical rib, and mild upper thoracic scoliosis causing prominence of the first rib on one side. The detection of variants by physical examination or more easily by review of the chest x-ray film may in selected instances obviate the need for costly diagnostic procedures and unnecessary biopsies. We call attention to this condition and describe our experience with four patients.

Complications requiring operative intervention after gastric bariatric surgery

In a series of 565 morbidly obese patients having one of five gastric bariatric procedures done at North Carolina Memorial Hospital between May 1975 and December 1982, 55 patients had 58 complications requiring reoperation. These complications included a leak from the stomach or anastomosis, stomal obstruction, and subphrenic abscess. Weight loss after vertical banded gastroplasty appears to be comparable to that following gastric bypass with Roux-en-Y gastrojejunostomy. The complication rate of vertical banded gastroplasty is the lowest of the gastric obstructive operations we have done.
