Anticoagulants are vital for managing thromboembolic diseases, with the choice of therapy influenced by patient-specific factors like age, body weight, renal function, and comorbidities. Direct oral anticoagulants (DOACs) are favored for their predictable effects and ease of use, though traditional vitamin K antagonists (VKAs) remain important in certain cases. Clinicians must carefully consider drug interactions, patient preferences, and clinical guidelines to optimize therapy and minimize risks. This study aims to analyze the impact of these variables on anticoagulant prescribing practices and associated outcomes. Primary Objective of study is to evaluate the factors influencing anticoagulant prescription in patients. Secondary Objective of the study is assessing the outcomes in patients who are prescribed anticoagulants. The study is designed as single-center, prospective, observational study. The Inclusion criteria for study is for All IPD and OPD patients who require VKAs or NOACs and Patients who are not willing to participate in the study are excluded. At visit 1, data parameters like patient demography and Clinical Details will be recorded such as Indication, Anticoagulant dose/frequency, expected duration, Reason for choice, Thrombosis etiology/site. On Telephonic Follow-Up,  visit 2 (3rd month) and visit 3 (6th month) certain data will be recorded such as Adverse Events and if yes, its Occurrence information. and Symptomatic Relief. Total sample size of study is 86 cases and study duration is 1 year. The Endpoints of study is To identify the key factors that influence the prescription of anticoagulants in patients, Evaluate the distribution of different types of anticoagulants prescribed, Assess the adherence rates to prescribed anticoagulant therapy and Identify factors contributing to non-adherence, including patient follow-up, and monitor side effects
