A physics and dosimetry database to support quality improvement throughout Michigan

An important aspect of Big Data is the use of information to continuously improve the quality of care for patients. In addition to clinical data, MROQC collects key dosimetry and physics information for eligible breast and lung cancer patients. With respect to the physics and dosimetry data, the registry allows analysis and comparison of the use of different treatment techniques and equipment for patient care. For example, the radiation therapy community has been unable to determine how frequently techniques such as deep inspiration breath hold (DIBH) are used outside of clinical trials. Deep inspiration breath hold, typically done with a device such as a spirometer, is used to reduce the dose to the heart for patients treated for cancer of the left breast. Data from patients enrolled in MROQC showed that about 30% of patients treated to the left breast used deep inspiration breath hold. In addition, the database can be used to connect the doses for targets and organs-at-risk as well as for the detail plan information (DICOM) files with information on both physician and patient-reported outcomes.
