About ERAS

Enhanced Recovery After Surgery (ERAS) at Massachusetts General Hospital is a patient-centered, evidence-based approach to surgical care that empowers you, the patient, to be a partner in your own care. Because all commonly performed procedures at Mass General set their standards to ERAS, you can be confident that you will receive best-known care before, during and after your procedure.

The ERAS team consists of clinicians involved in your care throughout the entire process, including pre-procedure preparation, the procedure itself, anesthesia, perioperative services, pharmacy, nursing, post-operative care and follow-up.

Each stage of ERAS is tailored to support you in your goals, such as to:

  • Minimize pain
  • Avoid complications
  • Improve recovery after the procedure
  • Decrease length of hospital stay
  • Allow for earlier return to daily life, such as normal diet and exercise

Patient Education by Procedure

Prior to your procedure, your care team will provide you with instructions, prescriptions and directions for how to pick up your supplies from the Mass General Pharmacy or elsewhere.

Mass General has created a variety of materials to help you prepare for your procedure, ensure better recovery and return to normal life as soon as possible.
