- $315.4 million spent. SURGEONS IN MOUNT AUBURN HOSPITAL'S GENERAL SURGERY DIVISION USE THE LATEST TECHNOLOGIES COMBINED WITH ADVANCED SURGICAL EXPERTISE TO PERFORM SURGERIES THAT ARE AS MINIMALLY INVASIVE AND PAINLESS AS POSSIBLE. MAH SURGEONS PERFORM BOTH ELECTIVE AND EMERGENT SURGERIES. ELECTIVE SURGERY INVOLVES A COMBINATION OF DIAGNOSTIC AND INTERVENTIONAL PROCEDURES RESULTING IN PERTINENT FOLLOW-UP WITH THE PATIENT'S REFERRING PHYSICIAN. IT IS PLANNED FOR AND SCHEDULED IN ADVANCE. EMERGENT SURGERY IS MOST OFTEN THE RESULT OF A MEDICAL EMERGENCY, AND IS MOST OFTEN REFERRED FROM AN EMERGENCY DEPARTMENT PHYSICIAN. IN EITHER SITUATION, MOUNT AUBURN'S SURGEONS ARE AVAILABLE TWENTY-FOUR HOURS A DAY, SEVEN DAYS A WEEK, TO ENSURE THAT PATIENTS RECEIVE THE MOST ADVANCED TREATMENT POSSIBLE. MAH SURGEONS FOCUS ON A DUAL MISSION OF CLINICAL CARE AND PATIENT EDUCATION. BECAUSE THE HOSPITAL IS A TEACHING HOSPITAL OF HARVARD MEDICAL SCHOOL, IT IS ABLE TO OFFER MORE SURGICAL SERVICES THAN MOST HOSPITALS OF SIMILAR SIZE, INCLUDING NEUROSURGERY AND CARDIOVASCULAR SURGICAL PROCEDURES, AS WELL AS CONTINUAL SURGICAL RESPONSES IN ALL DISCIPLINES. MAH IS ALSO SMALL ENOUGH TO OFFER PERSONALIZED CARE THROUGHOUT A PATIENT'S SURGERY, INCLUDING PREPARATION AND RECOVERY. THE HOSPITAL IS ENRICHED BY THE ENTHUSIASM OF OUR MEDICAL RESIDENTS.
