Postoperative Antibiotic Management Duration Following Surgery for Intravenous Drug Abuse (IVDA) Endocarditis (OPTIMAL)

2109416021

The purpose of this study is to determine the safety and compliance of initial intravenous (IV) antibiotics followed by oral antibiotic therapy following uncomplicated IVDA endocarditis. Endocarditis has a high rate of sickness and death, involves a long hospitalization and a long-term use of IV antibiotics necessitating six (6) weeks of in-patient hospital stay, and comes with a high cost.
