Although risk adjustment remains a cornerstone for comparing outcomes across hospitals, optimal strategies continue to evolve in the presence of many confounders. We compared conventional regression-based model to approaches particularly suited to leveraging big data.
The timeline table highlights the important data submission harvest and adjudication dates for the current and near-term fiscal years. Hospitals must submit their first harvest by the first business day of the month. The records submitted for each quarter are based on the date the cardiac surgery or PCI procedure occurred on.
Submission Policies Hospital data extracts must be submitted quarterly to Mass-DAC and uploaded to the Mass-DAC Secure Document Repository which is on the Harvard Medical School (HMS)virtual private network (VPN) at https://secure.med.harvard.edu/. Each hospital must have at least one data manger with a HMS VPN sponsored account or a HMS eCommons account through a HMS affiliated institution who can access the secure repository. All files uploaded to the repository should be encrypted with PGP encryption keys.
All Massachusetts hospitals that perform angioplasty or percutaneous coronary interventions (PCI) must submit patient and operator specific data to Mass-DAC, including in-hospital mortality data. Hospitals must utilize the American College of Cardiology (ACC) National Cardiovascular Data Registry (NCDR) and the supplemental Mass-DAC field specifications for extra fields required by Massachusetts. All data will be collected with no exclusions, including identifying demographic information on both patient and physician.
All Massachusetts hospitals that perform cardiac surgery must submit patient and surgeon specific data, and all hospitals that perform angioplasty or PCIs must submit patient and physician operator specific data. The hospital data managers act as the gatekeepers for each site’s data and are the key point of contact for most Mass-DAC communications and activities.
