A Study Related to the VOYAGER PAD Trial to Learn More About the Target Population for Xarelto in French Patients

Peripheral Artery Disease

This is a study to learn more about French patients who have peripheral artery disease (PAD) and who have had a revascularization procedure. With this procedure, doctors use surgery or a thin tube (called a catheter) to open a narrow or blocked blood vessel in the lower limbs. In a previous Bayer trial called VOYAGER PAD, researchers studied Xarelto in participants with PAD who had recently had a revascularization procedure in their lower leg. The researchers studied how well Xarelto worked and how safe it was in these participants. Based on the results of the VOYAGER PAD trial, the researchers in this study want to learn the number of patients with PAD who had a revascularization procedure in France from January 1st, 2016 to December 31st, 2019. This can help the researchers learn more about the target population (a specific group of people) who could potentially receive treatment with Xarelto. Xarelto is available for doctors in France to prescribe to patients who have the following conditions: * to reduce the risk of another heart attack or of dying from a disease related to the heart or the blood vessels in adults with acute coronary syndrome (a group of conditions that includes heart attack and unstable angina, a severe type of chest pain) who have had an increase in certain cardiac blood tests * to reduce the risk of getting blot clots (atherothrombotic events) in adults at a high risk of getting a blood clot due to a coronary artery disease or peripheral artery disease which causes symptoms * to prevent blood clots in the veins after a hip or knee replacement operation in adults * to prevent blood clots in brain (stroke) and other blood vessels in the body in adults who have a form of irregular heart rhythm called non-valvular atrial fibrillation * to treat blood clots in the veins of the legs (deep vein thrombosis) and in the blood vessels of the lungs (pulmonary embolism), and to prevent blood clots from re-occurring in the blood vessels of the legs and/or lungs in adults * to treat blood clots and prevent re-occurrence of blood clots in the veins or in the blood vessels of the lungs in full-term newborn babies, infants and toddlers, children and adolescents below 18 years following an initial treatment of at least 5 days with injectable medicines used to treat blood clots All the patients in this study will have PAD in their lower leg. They will all have had a revascularization procedure during a hospital stay in France between January 1st, 2016 and December 31st, 2019. The researchers will collect the patients' health data from the French National Health Insurance (NHI) hospital discharge database (PMSI). The researchers will look at the health data from all patients with PAD who had a revascularization procedure and also patients who could have joined the VOYAGER PAD trial. This group will not include any patients who have health conditions other than PAD. The researchers will review each patient's medical records until December 31st, 2019 or earlier if the patient has died. The researchers will also look at any previous medical records from the date of each patient's revascularization procedure back to January 1st, 2014. The researchers will use these medical records to look for any health conditions other than PAD that the patients may have had before their revascularization procedure after January 1st 2016. The main question the researchers want to answer in this study is: how many patients with PAD had a revascularization procedure between January 1st, 2016 and December 31st, 2019?
