Methodology for the Fortune/IBM Watson Health 50 Top Cardiovascular Hospitals 2021 – Fortune

50 Top Cardiovascular Hospitals

To determine the hospitals included on the Fortune/IBM Watson Health 50 Top Cardiovascular Hospitals list, IBM Watson Health researchers evaluated over 951 short-term, acute care, nonfederal U.S. hospitals that treat a broad spectrum of cardiology patients. All research was based on the following public data sets: Medicare cost reports, Medicare Provider Analysis and Review (MEDPAR) data, and measures data from the Centers for Medicare & Medicaid Services (CMS) Hospital Compare website.

The focus of the study is on hospitals that offer both medical and surgical treatment options for cardiovascular patients, specifically those with Acute Myocardial Infarction (AMI) or Heart Failure (HF), and those having a bypass surgery (CABG) or angioplasty (PCI). To build the database, we included all hospitals that had, in the two most recent data years combined, at least 30 unique cases in each of the four patient groups: Acute Myocardial Infarction (AMI), Heart Failure (HF), Coronary Artery Bypass Graft (CABG), and Percutaneous Coronary Intervention (PCI).  Each patient group is mutually exclusive, by design. To define patient diagnoses, ICD-10-CM codes are used.
