Chest Radiograph Interpretation: Online Teaching Resources for Non-Radiologists.

Chest radiographs provide vital information to clinicians. Medical professionals need to be proficient in interpreting chest radiographs to care for patients. This review examines online methods for teaching chest radiograph interpretation to non-radiologists. An online database search of PubMed and the Cochrane Databases of Systematic Reviews revealed 25 potential evidence sources. After using the similar articles tool on PubMed, eight evidence sources met the inclusion criteria. Three sources supported the use of online learning to increase students' confidence regarding chest radiograph interpretation. The evidence suggests that through self-directed online learning, students can learn skills to diagnose disease processes as well as to confirm the placement of invasive lines and tubes. Using online learning for teaching radiograph interpretation to non-radiologists is an evolving practice. A flexible schedule is needed when implementing the electronic learning process for busy students. Monitoring module completion and postlearning assessment of knowledge is important. Further research is warranted on electronic teaching of chest radiograph interpretation in nurse anesthesia programs. A list of potential online resources for teaching chest radiograph interpretation is presented.

30-Day Post-Discharge Prophylaxis with Rivaroxaban Prevents Porto-mesenteric Venous Thrombosis Following Laparoscopic Sleeve Gastrectomy.

INTRODUCTION: Porto-mesenteric venous thrombosis (PMVT) is a significant complication that occurs more frequently after laparoscopic sleeve gastrectomy (SG) than other bariatric procedures and presents later than other venous thromboembolic (VTE) events often 2 weeks after the operation. The common current practice in bariatric surgery of perioperative chemoprophylaxis until discharge may not adequately prevent PMVT. Therefore, a 30-day post-discharge chemoprophylaxis (PDC) might reduce the incidence of PMVT. The objective of this study is to determine whether 30-day PDC with rivaroxaban 10 mg daily following SG can reduce the incidence of PMVT. METHODS: In a retrospective cohort study, 292 consecutive patients undergoing SG by a single surgeon were either prescribed rivaroxaban 10 mg daily for 30 days upon discharge (group A) or did not receive any PDC (group B). Primary outcome was PMVT and secondary outcome was bleeding. Patients on chronic anticoagulation therapy were excluded from the study. RESULTS: PMVT events differences were significant between the groups while bleeding events were not. Group A had zero PMVT events, while group B had four (p = .045). There were 4 bleeding events in group A and 7 bleeding events on group B (p = .341). CONCLUSION: A 30-day PDC regimen of rivaroxaban 10 mg daily is both safe and effective. This study demonstrated zero PMVT events without an increased risk of bleeding using this regimen.
