A large single-center experience with treatment of patients with crotalid envenomations: outcomes with and evolution of antivenin therapy.

BACKGROUND: Antivenin (crotalid) polyvalent (ACP; Antivenin Crotalidae Polyvalent; Wyeth, Melville, NY) is associated with frequent allergic reactions. Allergic reactions are fewer with ovine Fab antivenin (FabAV). This study describes the management of crotalid envenomations in patients treated with FabAV or ACP, and without antivenin. METHODS: We performed a retrospective chart review of crotalid envenomations over 10 years. Demographic data, hematologic profiles, details of antivenin administration, and in-hospital morbidity and mortality were collected. RESULTS: There were no mortalities and a single amputation. Fewer fasciotomies were performed in the FabAV (9%) group versus the ACP group (24%). Mean hospital stay was 3.4 days. No allergic reactions were associated with FabAV. Fourteen of 211 reactions were associated with ACP (P < .001). Coagulopathy was frequent. CONCLUSIONS: FabAV represents an improvement in management of crotalid envenomations because of reduced allergic reactions. Serious morbidity and mortality is rare. Coagulopathy is frequent but bleeding is not. Limb salvage is high. Surgical debridement and ACP are contraindicated when FabAV is available.

Transparent and open discussion of errors does not increase malpractice risk in trauma patients.

OBJECTIVE: We set out to determine if there is an increased medical malpractice lawsuit rate when trauma patient cases are presented at an open, multidisciplinary morbidity and mortality conference (M&M). INTRODUCTION: Patient safety proponents emphasize the importance of transparency with respect to medical errors. In contrast, the tort system focuses on blame and punishment, which encourages secrecy. Our question: Can the goals of the patient safety movement be met without placing care providers and healthcare institutions at unacceptably high malpractice risk? METHODS: The trauma registry, a risk management database, along with the written minutes of the trauma morbidity and mortality conference (M&M) were used to determine the number and incidence of malpractice suits filed following full discussion at an open M&M conference at an academic level I trauma center. RESULTS: A total of 20,749 trauma patients were admitted. A total of 412 patients were discussed at M&M conference and a total of seven lawsuits were filed. Six of the patients were not discussed at M&M prior to the lawsuit being filed. One patient was discussed at M&M prior to the lawsuit being filed. The incidence of lawsuit was calculated in three groups: all trauma patients, all trauma patients with complications, and all patients presented at trauma M&M conference. The ratio of lawsuits filed to patients admitted and incidence in the three groups is as follows: All Patients, 7 lawsuits/20,479 patients (4.25 lawsuits/100,000 patients/year); M&M Presentation, 1 lawsuit/421 patients (29.6 lawsuits/100,000 patients/year); All Trauma Complications, 7 lawsuits/6,225 patients (14 lawsuits/100,000 patients/year). Patients with a complication were more likely to sue (P < 0.01); otherwise, there were no statistical differences between groups. CONCLUSIONS: A transparent discussion of errors, complications, and deaths does not appear to lead to an increased risk of lawsuit.

Trauma surgery malpractice risk: perception versus reality.

OBJECTIVE: We set out to compare the malpractice lawsuit risk and incidence in trauma surgery, emergency surgery, and elective surgery at a single academic medical center. SUMMARY AND BACKGROUND DATA: The perceived increased malpractice risk attributed to trauma patients discourages participation in trauma call panels and may influence career choice of surgeons. When questioned, surgeons cite malpractice risk as a rationale for not providing trauma care. Little data substantiate or refute the perceived high trauma malpractice risk. We hypothesized that the malpractice risk was equivalent between an elective surgical practice and a trauma/emergency practice. METHODS: Three prospectively maintained institutional databases were used to calculate and characterize malpractice incidence and risk: a surgical operation database, a trauma registry, and a risk management/malpractice database. Risk groups were divided into elective general surgery (ELECTIVE), urgent/emergent, nontrauma general surgery (URGENT), and trauma surgery (TRAUMA). Malpractice claims incidence was calculated by dividing the total number of filed lawsuits by the total number of operative procedures over a 12-year period. RESULTS: Over the study period, 62,350 operations were performed. A total of 21 lawsuits were served. Seven were dismissed. Three were granted summary judgments to the defendants. Ten were settled with payments to the plaintiffs. One went to trial and resulted in a jury verdict in favor of the defendants. Total paid liability was 4.7 million dollars(391,667 dollars/year). Total legal defense costs were 1.3 million dollars(108,333 dollars/year). The ratio of lawsuits filed/operations performed and incidence in the 3 groups is as follows: ELECTIVE 14/39,080 (3.0 lawsuits/100,000 procedures/year), URGENT 5/17,958, (2.3 lawsuits/100,000 procedures/year), and TRAUMA 2/5312 (3.1/100,000 procedures/year). During the study period, there were an estimated 49,435 trauma patients evaluated. The incidence of malpractice lawsuits using this denominator is 0.34 lawsuits/100,000 patients/year. CONCLUSIONS: These data demonstrate no increased risk of lawsuit when caring for trauma patients, and the actual risk of a malpractice lawsuit was low.

Appendicitis: selective use of abdominal CT reduces negative appendectomy rate.

BACKGROUND: Recent literature supports the use of CT for all patients with right lower quadrant pain to improve diagnostic accuracy and reduce hospital cost. Our current practice at a large teaching hospital is to use CT only for patients whose diagnosis remains in question after a thorough history, physical examination, and focused laboratory assessment. In consideration of a more liberal use of CT for right lower quadrant pain, we reviewed our experience with selective CT and the effect this has had on our practice, paying particular attention to perforation rate and negative appendectomy rate. MATERIALS AND METHODS: A retrospective chart review was performed for all patients who underwent appendectomy in 1995 and 1998. These two patient populations were evaluated for patient demographics, use of CT scan, perforation rate, and incidence of negative appendectomy. RESULTS: Three hundred ninety-four patients underwent appendectomy in 1995 versus 372 in 1998. Gender (64% male in 1995 vs. 60% in 1998), age (mean 24.9 vs. 25.5) and perforation rate (31% in 1995 vs. 29% in 1998) did not change. The use of CT increased in 1998 (12% vs. 34%, p < 0.001) and overall nontherapeutic appendectomy decreased (14% vs. 7%, p < 0.005). This decrease was seen in patients who were operated without CT (13% vs. 7%, p < 0.03) and after CT (19% vs. 6%, p < 0.02). CONCLUSION: Selective use of CT scan in patients presenting with right lower quadrant pain is helpful in reducing the incidence of nontherapeutic appendectomy.

Seven hundred fifty-three consecutive deaths in a level I trauma center: the argument for injury prevention.

BACKGROUND: The past century has seen improvement in trauma care, with a resulting decrease in therapeutically preventable deaths. We hypothesize that further major reduction in injury mortality will be obtained through injury prevention, rather than improvements in therapy. METHODS: Seven hundred fifty-three deaths in an American College of Surgeons-verified, Level I trauma center were reviewed as they occurred. Deaths were classified as therapeutically not preventable, possibly preventable, or preventable. These charts were also reviewed for factors that might have prevented or lessened the severity of the injury. RESULTS: Mean age was 43, mean Glasgow Coma Scale score was 5, mean Revised Trauma Score was 4, mean Injury Severity Score was 41, and mean probability of survival was 0.25 (according to TRISS). Forty-six percent underwent cardiopulmonary resuscitation in the field, 52% died within 12 hours, 74% died within 48 hours, and 86% died within 7 days. Primary causes of death included central nervous system injury in 51%, irreversible shock in 21%, multiple injuries (shock plus central nervous system injury) in 9%, multiple organ failure/sepsis and other causes in 3%, and pulmonary embolus in 0.1%. Seven hundred one (93%) were classified as not preventable with a change in therapy, 32 (4.2%) were classified as potentially preventable with a change in therapy, and 20 were classified as preventable with a change in therapy (2.6%). Forty-six percent had cardiopulmonary resuscitation performed before or immediately on arrival to the hospital. Another 23% had vital signs present on arrival, but had a Glasgow Coma Scale score of <or= 4. Of the 546 unintentionally injured patients, 58% had an identifiable factor that contributed to the presence and/or severity of the injury (intoxication, restraint and helmet use), with 28% of patients having a positive blood alcohol level. Of the 206 patients with intentional injuries, 44% were intoxicated at the time of their death. Commensurate with driving-while-intoxicated prevention program(s), the percentage of intoxicated patients significantly ( p= 0.03) decreased from 45% to 34% over the same 7-year period. CONCLUSION: Dramatically improving therapy (no errors, cure for multiple organ failure, sepsis, and pulmonary embolus) in a modern trauma system would decrease trauma mortality by 13%. In contrast, more than half of all deaths are potentially preventable with preinjury behavioral changes. Injury prevention is critical to reducing deaths in the modern trauma system.
