Objective: To audit the prescription and implementation of deep vein thrombosis (DVT) prophylaxis in general surgical patients in a teaching hospital. Methods: All inpatients on three general surgical wards were audited for adequacy of prescription and implementation prophylaxis (audit A). A repeat audit 3 months later (audit B) closed the loop. The groups were compared using the chi-square test. Results: In audit A 50 patients participated. Prophylaxis was correctly prescribed in 36 (72%) and implemented in 30 (60%) patients. Eighteen patients at moderate or high risk (45%) received inadequate prophylaxis. Emergency admission, pre-operative stay and inadequate risk assignment were associated with poor implementation of protocol. In audit B 51 patients participated. Prescription was appropriate in 45 (88%) and implementation in 40 (78%) patients (p< 0.05). Eleven patients at moderate or high risk received inadequate prophylaxis. Seven of 11 high-risk patients in audit A (64%) received adequate prophylaxis, in contrast to all high-risk patients in audit B. The decision not to administer prophylaxis was deemed appropriate in 5 of 15 (30%) in audit A compared with 6 of 10 (60%) in audit B. Conclusion: Increased awareness, adequate risk assessment, updating of protocols and consistent reminders to staff and patients may improve implementation of DVT prophylaxis.

Introduction. It is acknowledged that patients undergoing neurosurgery with neurological illness are at higher risk of lower extremity deep vein thrombosis (DVT). As an underlying life-threatening complication, the incidence and risk factors for high-risk patients with lower extremity deep vein thrombosis are still controversial in relative high-risk patients after neurosurgery. Materials and Methods. A total of 204 patients who underwent neurosurgery and were considered as a high-risk group of DVT according to times of stay in bed more than 3 days were enrolled in this study. We evaluated the lower extremity DVT by using Color Doppler Ultrasound System (CDUS). Clinical parameters of patients at the time of admission and postoperation were recorded and prepared for further analysis. Early predictive factors for postoperative lower extremity DVT were established. Diagnostic performance of predictive factors was evaluated by using receiver operating characteristic (ROC) curve analysis. Results. The overall incidence rate of DVT in 204 enrolled patients was 30.9%. Multivariate logistic regression indicated that hypertension (OR 3.159, 95% CI 1.465-6.816; P=0.003), higher postoperative D-dimer (OR 1.225, 95% CI 1.016-1.477; P=0.034), female (OR 0.174, 95% CI 0.054-0.568; P=0.004), and lower GCS score (OR 0.809, 95% CI 0.679-0.965; P=0.013) were independently associated with incidence of DVT in patients after neurosurgery. The logistic regression function (LR model) of these four independent risk factors had a better performance on diagnostic value of DVT in patients after neurosurgery. Conclusion. The combined factor was constructed by hypertension, postoperative D-dimer, gender, and GCS score, and it might be a more handy and reliable marker to stratify patients at risk of DVT after neurosurgery.

Abstract Background: Deep vein thrombosis (DVT) is a silent killer in hospitalized patients. Its prevalence in Thai population may be different from Western countries. Objective: To evaluate recognized risk factors for DVT in high-risk Thai patients according to the American College of Chest Physicians (ACCP). Methods: Hospitalized patients were prospectively enrolled at the Department of Medicine, Khon Kean Hospital. The study period was January 2010 to March 2011. Inclusion criteria were patients who were admitted with either (1) heart or respiratory failure or (2) one of the following conditions: cancer, sepsis, acute stroke, or inflammatory bowel disease. The admission length was at least four days. Patients were excluded if the hospitalization was because of venous thromboembolism or if there was a requirement for heparin therapy. Results: One hundred patients met the study criteria during the study. Of those, 5 patients (5%) had evidence of DVT by ultrasonography. None of these patients had pulmonary embolisms by computed tomographic angiography. In the multiple logistic regression analysis, only acute stroke was significantly associated with DVT. The adjusted odds ratio (OR) was 19.72; (95% confidence interval (CI) 1.37, 284.37). DVT was the only significant factor associated with death during admission with adjusted OR of 30.76 (95% CI: 2.02, 469.03). Conclusions: The prevalence of DVT in hospitalized high-risk patients by ACCP criteria was low. Admission because of acute stroke may increase the risk of DVT and having DVT may result in high mortality.

Objective To determine the role of digital photoplethysmography in screening asymptomatic patients who are susceptible for developing deep vein thrombosis. Methods Three hundred and thirty-seven limbs in 169 patients who were high risk for development of deep vein thrombosis were assessed by ultrasonography digital photoplethysmography and the results were compared. Results Thirteen limbs were found to have deep vein thrombosis as demonstrated by ultrasonography. All limbs with a venous refilling time greater than 12 seconds had a normal ultrasonography. Compared with ultrasonography and using refilling time less than 12 seconds as the cutoff point, digital photoplethysmography achieved a sensitivity, specificity, positive predictive value, and negative predictive value of 100%, 73.8%, 13.3%, and 100% respectively, for detecting deep vein thrombosis in asymptomatic high-risk patients. Conclusion Digital photoplethysmography is a simple, noninvasive, and highly sensitive test for screening of deep vein thrombosis.
