Universities and most hospitals have in-house IRBs. This ability is described as its "power", which must be calculated before initiating a study to figure out if the study is worth its costs. The IRB scrutinizes the study both for medical safety and for protection of the patients involved in the study, before it allows the researcher to begin the study. Neither is an absolute criterion; both safety and efficacy are evaluated relative to how the treatment is intended to be used, what other treatments are available, and the severity of the disease or condition. Where will the study take place? Will my study partner be compensated for his or her time? Other people say they want to help researchers learn more about certain health problems.
