Randomized Controlled Trial Multicenter Study Clinical Trial
Cost savings in duodenal ulcer therapy through Helicobacter pylori eradication compared with conventional therapies: results of a randomized, double-blind, multicenter trial. Gastrointestinal Utilization Trial Study Group.
We hypothesized that treatment of duodenal ulcer disease with antibiotic therapy directed toward Helicobacter pylori infection is more cost-effective than therapy with antisecretory agents. ⋯ Combination therapy with clarithromycin and omeprazole resulted in significantly fewer uses of ulcer-related health care resources than conventional antisecretory therapy during a 1-year follow-up and significant savings in associated costs during the same period. Patients who received clarithromycin plus omeprazole also showed a significantly improved clinical outcome compared with patients who received only omeprazole or ranitidine.

Despite low molecular weight heparin prophylaxis, the incidence of venographically detected, residual deep vein thrombosis after hip and knee arthroplasty remains high, at approximately 15% and 30%, respectively. Most of these thrombi are asymptomatic and of unknown clinical significance. Nevertheless, because they have the potential to grow, limiting prophylaxis to the in-hospital period may provide inadequate protection. ⋯ Postoperative prophylaxis with enoxaparin for a mean of 9 days is associated with a clinically acceptable rate of symptomatic venous thromboembolism and major hemorrhage. Predischarge compression ultrasonography cannot be justified.
