Estimated Regression Coefficients and Covariance Matrix “A Prediction Model to Identify Patients at High Risk for 30-Day Readmission After Percutaneous Coronary Intervention” by Jason H. Wasfy, MD, et. Al. published in Circulation: Cardiovascular Quality and Outcomes, 2013; volume 06, pages 429-435. The Excel file available for download below contains four tabs for the estimated regression coefficients, corresponding standard errors, 95% confidence intervals, and covariance matrices for the pre-PCI and discharge model set of predictors used in the paper. The estimates provided are based on the full cohort and will differ from those reported in the published paper. Download the Wasfy’s paper model coefficients and covariance matrix The data tabs included: Pre-PCI Estimates Pre-PCI Covariance Matrix Discharge Model Estimates Discharge Model Covariance Matrix The variables used in the paper were developed using mostly American College of Cardiology National Cardiovascular Data Registry (ACC-NCDR) CathPCI version 3 data collection instrument variable definitions. The Insurance categories were defined using the Massachusetts Center for Health Information and Analysis Acute Hospital Case Mix Databases (CHIA-AHCMD) for inpatient discharges. The ACC-NCDR data collection form and definitions are avaible at, http://cvquality.acc.org/NCDR-Home/Data-Collection/What-Each-Registry-Collects.aspx .

The March-April 2013 issue of the Harvard Magazine featured the article “A Cardiac Conundrum” written by Alice Park about David Jones’ new book, Broken Hearts: The Tangled History of Cardiac Care (Johns Hopkins), published December 26, 2012. In her article, Park writes, During the twentieth century, heart disease began to climb from relative obscurity to its […]
Research Proposals for Use of Cardiac Registry Data Until further notice, Mass-DAC is no longer accepting new applications for “Proposals for Data Requests” due to changes requested by the Massachusetts Hospital Research and Education Association, MHREA, in the Massachusetts Department of Public Health/Mass-DAC Contract and the need for new policies and procedures. Please watch the website for updates.
Mass-DAC model coefficients are freely available for public use (Click here to view all sets). If you would like to use Mass-DAC regsitry data for research a request must be made directly through Mass-DAC and the Massachusetts Department of Public Health. To submit a research request using of Mass-DAC data you need to download the “Proposal for Data Request” form and submit it to Mass-DAC for review. All proposal data requests require approval by the Massachusetts Cardiac Surgery Database Registry Publications Committee and final review for data use by the Massachusetts Department of Public Health. This process may take several months. For additional details please contact Ann Lovett or Caroline Wood at firstname.lastname@example.org. The fee schedule is still waiting for final approval from the Massachusetts Department of Public Health and will be posted when ready.

Beginning with fiscal year 2007, Mass-DAC has created three mortality risk calculators, annually. Some researchers have expressed an interest in utilizing the mortality risk calculators from all years, as the models have evolved. The Excel version of the calculators from each report year are available for download in the table below. For the most current risk calculators and additional details, please visit the Public Outreach-Risk Calculator page.
