Choosing a doctor is only part of a medical procedure. Where that doctor or surgeon (literally) operates matters just as much: the hospital’s track record, its specialized teams, its post-op care—and yet most of us don’t know how important picking that the building really can be. This guide aims to close that gap.
Working with Castle Connolly, the veteran research firm that’s spent more than three decades vetting Top Doctors nationwide, we’re presenting a data-driven look at which Greater Boston hospitals excel at which procedures. The rankings draw on medical insurance claims data spanning multiple commercial and public payors, tracking real patient outcomes—mortality rates, complication rates, safety records, recovery times—from before a procedure through discharge and beyond. Castle Connolly layers in its own physician nomination data too, accounting for the doctors who make each hospital’s specialty program what it is.
The result is a practical map of the region’s medical landscape, organized by specialty and by procedure, from cardiac surgery to hip replacements to mastectomies. Whether you’re facing a scheduled operation or just want to know your options before you need them, consider this your starting point for figuring out not just who should operate, but where.

Recognizing that a patient’s choice of hospital is equally as important as their choice of doctor, Castle Connolly Top Hospitals aims to provide a reliable, data-driven resource for identifying the best hospitals for various medical procedures. The resulting lists of Top Hospitals focus on the best options chosen by Castle Connolly for patients preparing for a medical procedure, whether they are looking within their own community or across the country for care.

Using this data, hospitals are assessed for each medical procedure, analyzing the patient outcome performance metrics, including mortality and complication rates, patient safety, and recovery and discharge rates.
In addition to the patient outcome components of the methodology, Castle Connolly also incorporates Castle Connolly Top Doctors and physician nomination data sources to reflect both the impact of high-quality providers at each hospital, as well as the experience and expertise of doctors when it comes to selecting a hospital.
