Background: Clinical practice guidelines recommend that cerebral venous thrombosis (CVT) be managed with long-term anticoagulant therapy using warfarin or low-molecular-weight heparin (LMWH) for 3 to 12 months. However, oral factor Xa inhibitors may offer preferable alternative treatment options for these patients. Objective: The primary objective was to determine the effectiveness and safety of rivaroxaban or apixaban compared with warfarin or enoxaparin as long-term anticoagulation therapy for patients with a new diagnosis of CVT. Methods: This was a single-center retrospective review of patients with newly diagnosed CVT who received acute and maintenance anticoagulation treatment. Study groups compared patients who received warfarin, enoxaparin, or an oral factor Xa inhibitor as their maintenance anticoagulant. The primary outcome was recurrent thrombotic events while on anticoagulation. Secondary outcomes included modified Rankin Scale, improved cerebral venous sinus opacification, duration of anticoagulant therapy, bleeding events during anticoagulant therapy, and adverse effects. Results: A total of 119 patients were included in the analysis: warfarin (89), enoxaparin (11), and oral factor Xa inhibitor (19). The risk of recurrent thrombotic events were 11.2%, 0%, and 10.5% in the warfarin, enoxaparin, and oral factor Xa inhibitor treatment groups, respectively ( P = 0.7635). There were no significant between-group differences observed regarding any of the secondary outcomes. Conclusions: Although the sample size is limited, these findings indicate that oral factor Xa inhibitors are a reasonable treatment option for patients with CVT. There was a trend toward more persistent symptoms in patients on warfarin, suggesting a potential improvement in recovery among patients that received an oral factor Xa inhibitor.
Background: Opioids are utilized for pain management during and after mechanical ventilation in the intensive care unit (ICU). Objective: The purpose of this study was to determine the percentage of potentially unnecessary opioid prescriptions on discharge in previously opioid-naïve patients. Methods: This retrospective cohort study included mechanically ventilated, opioid-naïve ICU patients who received opioids. The primary outcome of this study was the discrepancy between the amounts of opioids prescribed at discharge versus those likely required based on actual 24-hour prehospital discharge opioid requirements. Results: A total of 71 patients were included. Of these, 63.3% (n = 45) of discharge prescriptions were in alignment with 24-hour predischarge requirements, and 36.7% (n = 26) of discharge prescriptions were in excess of calculated predischarge requirements. At discharge, 57.7% (n = 41) of patients received a nonopioid analgesic. Multivariable linear regression revealed that cardiothoracic ICU admission was associated with an increased risk of inappropriate discharge opioid prescribing, whereas a shorter duration of inpatient oral opioid therapy decreased risk of inappropriate discharge prescribing. Conclusion and Relevance: Opioid prescribing for previously mechanically ventilated patients warrants improvement as a part of the discharge planning process. Application of these data may aid in the reduction of opioid overprescribing at discharge after an ICU stay.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
