To the Editor We read the article by Sanghavi et al1 with great interest and applaud the authors on their use of the Medicare claims database to examine patient-oriented outcomes resulting from advanced life support (ALS) vs basic life support (BLS) treatment for out-of-hospital cardiac arrest (OHCA). However, we feel to conclude that BLS offers a survival advantage is unwarranted given the data presented.
