Alcoholism is today the greatest medical and social problem. Due to the fact that it is frequently connected with aggressiveness, it can also be defined as a great and frequent forensic problem. The authors investigate the issue to what extent aggressiveness is medically justified. They offer guidelines regarding this problem in accordance with their everyday experience and medical criteria.
OBJECTIVE: Determine whether severe injury results in decreased plasma antithrombin (AT) activity and whether this decreased AT activity is associated with thromboembolic complications. DESIGN: Prospective observational. SUBJECTS: A total of 157 critically injured trauma patients. METHODS: Each patient underwent laboratory analysis on arrival to the emergency room at hours 8, 16, 24, and 48, and days 3, 4, 5, and 6. Laboratory analyses included AT, tissue factor pathway inhibitor, protein C, prothrombin fragment 1.2, thrombin-antithrombin complex, and D-dimer. Patients were followed for thromboembolic complications including: deep venous thrombosis (DVT), pulmonary embolus, disseminated intravascular coagulation (DIC) and adult respiratory distress syndrome (ARDS). RESULTS: Mean Injury Severity Score was 23 (+/-11). AT activity fell below normal in 95 (61%) patients; AT activity rose to greater than normal in 51 (32%) patients. Nine (6%) patients developed DVT, two (1%) pulmonary embolus, 13 (8%) DIC and 26 (17%) ARDS. Using logistic regression analysis, low AT levels were a significant predictor of DVT, DIC, and ARDS (p < 0.05). Supranormal At levels were associated with closed head injury (p < 0.05). D-dimer levels were inversely correlated with AT (p < 0.05). CONCLUSIONS: AT activity was depressed in critically injured patients. Patients with head injury developed supranormal AT activity. The risk factors for AT deficiency mimicked those for thromboembolism. Patients with decreased AT activity were at increased risk for thromboembolic complications. Given heparin's dependence on AT, these data call into question the use of unmonitored heparin thromboembolism prophylaxis.
Establishment of a multidisciplinary clinical pharmacology consult service (CPCS) can be an important adjunct to a successful formulary management system. This article describes the model of a CPCS developed at the University of California Davis Medical Center. The CPCS provides patient-specific consultations, serves a leadership role in directing the medical staff toward hospital-wide drug usage guidelines for high cost pharmaceutical agents, and enforces the P & T Committee adopted criteria on selected high-cost or high risk agents. The mission of the CPCS is to provide the P & T Committee with a multidisciplinary mechanism to educate health care providers, improve patient care, establish drug usage criteria, and enforce those criteria.
