• Official Title: VeriXAPPORT: Verification of XAPPORT: a Decision Support App for Physicians Used for Patients Anticoagulated With Rivaroxaban in Terms of Anticoagulation Management in Elective Surgery: Verification Process of Medical Decision Algorithm
• Brief Summary: This study shall determine whether XAPPORT - a mobile device app based on different guidelines, the summary of product characteristics of rivaroxaban, and clinical facts and practice - provides adequate guidance to physicians attending patients undergoing elective surgery, who have to interrupt treatment with rivaroxaban for surgery, in deciding how to approach the pre- and postoperative management of anticoagulation.
• Detailed Description: Study design: "retrospective/prospective" Observational study
• Study Type: Observational
• Study Design: Observational Model: Cohort; Time Perspective: Other
• Target Follow-Up Duration: Not Provided
• Biospecimen: Not Provided
• Sampling Method: Non-Probability Sample
• Study Population: At least 100 evaluable female or male inpatients shall be enrolled after having been discharged from hospital and provide data for analyses. Patients meeting all inclusion criteria and no exclusion criterion are suitable for this study. Enrolment will continue until at least 100 patients with complete data for analysis are available (i.e. 100 evaluable patients). An adequate representation of every bleeding and thromboembolism risk category per indication in the matrix will be taken into account.

Condition

• Atrial Fibrillation
• Venous Thromboembolism
• Pulmonary Embolism

Intervention

• Other: XAPPORT
  A mobile device app based on different guidelines provides adequate guidance to physicians attending patients undergoing elective surgery, who have to interrupt treatment with rivaroxaban for surgery, in deciding how to approach the pre- and postoperative management of anticoagulation.
• Other: Expert Panel ("gold standard")
  A national panel of experts comprising anesthetists and surgeons from various disciplines advised in developing an algorithm supporting physicians how to approach the perioperative management of anticoagulation in patients receiving rivaroxaban and requiring elective surgery.
