All patients must be evaluated by the Pre-Admission Testing Area (PATA) prior to a surgical procedure at Massachusetts General Hospital. Some patients are evaluated in person at the PATA clinic on the main campus, while other patients are eligible for a phone interview with the PATA phone program instead of a clinic visit. Ask your surgeon which type of evaluation is appropriate for you.
During the pre-admission process, a team of nurses, anesthesiologists and other clinicians work together to gather information about your medical and surgical history, and provide instructions about how you can prepare for an upcoming surgery.
It is important to complete your pre-admission appointment within 30 days before your surgery so that your procedure is not cancelled or delayed.
