The purpose of the Hyperbaric Oxygen Therapy Registry (HBOTR) is to provide real world patient outcome and side effect information from electronic health records submitted to a specialty specific hyperbaric registry as part of "Stage 2 of Meaningful Use," including data provided to meet PQRS requirements via the registry's QCDR mission. Goals include understanding the value of HBOT among patients treated for a variety of conditions in relation to the frequency and severity of HBOT side effects. While randomized, controlled trials can establish the efficacy of treatments like HBOT, because they routinely exclude patients with co-morbid conditions common to those patients seen in usual clinical practice, the results of RCTs are usually non-generalizable. Real world data can be used to better understand the effectiveness of HBOT among typical patients, as well as the risks associated with treatment.
