SINCE THE START OF THE PANDEMIC (THROUGH JUNE OF 2021), BILH HAS TREATED OVER 8,500 HOSPITALIZED PATIENTS WITH COVID-19 AND PERFORMED MORE THAN 700,000 COVID-19 DIAGNOSTIC TESTS. HIGHLIGHTS OF THE SYSTEM'S PANDEMIC RESPONSE IN FY 2020 INCLUDE: BILH QUICKLY ESTABLISHED AN EMERGENCY OPERATIONS CENTER ("EOC") TO ALIGN SYSTEM EFFORTS ACROSS ITS HOSPITALS AND OTHER BUSINESS UNITS AND WITH EXTERNAL ENTITIES, INCLUDING THE STATE GOVERNMENT. THE EOC HELD REGULAR MEETINGS WITH INCIDENT COMMANDERS, EMERGENCY MANAGERS, AND SENIOR LEADERS FROM BILH HOSPITALS, PRIMARY CARE, AND OTHER SYSTEM ENTITIES TO COORDINATE PLANS, POLICIES, AND COMMUNICATIONS. IT PARTICIPATED IN WEEKLY CONFERENCE OF BOSTON TEACHING HOSPITALS ("COBTH") CALLS AND MASSACHUSETTS DEPARTMENT OF PUBLIC HEALTH COMMAND CENTER CALLS. A KEY ROLE OF THE EOC INVOLVED MANAGING THE FLOW OF INTERNAL AND EXTERNAL INFORMATION TO ENSURE SITUATIONAL AWARENESS AND ALIGNMENT OF RESPONSES TO THE PANDEMIC. FINALLY, THE EOC WORKED WITH INTERNAL AND EXTERNAL PARTNERS TO CENTRALIZE COVID-19 RELATED DATA COLLECTION AND REPORTING FOR THE SYSTEM, COMMONWEALTH, AND FEDERAL GOVERNMENT. IN MARCH 2020, BETH ISRAEL DEACONESS MEDICAL CENTER ("BIDMC") BECAME ONE OF THE FIRST HOSPITAL LABORATORIES IN THE STATE TO BEGIN IN-HOUSE HIGH-THROUGHPUT POLYMERASE CHAIN REACTION ("PCR") COVID-19 TESTING FOR PATIENTS AND HEALTHCARE WORKERS. BIDMC'S LABORATORY PROVIDED THIS TEST TO BILH HOSPITALS AND OTHER COMMUNITY PARTNERS, SUCH AS HEALTH CENTERS AND CORRECTIONS FACILITIES, AT A TIME OF CRITICAL SUPPLY SHORTAGE. THROUGHOUT THE PANDEMIC, BILH WORKED TOWARD ADDITIONAL IN-HOUSE TESTING CAPABILITIES, INCLUDING HIGH-THROUGHPUT THERMO FISHER INSTRUMENTS AT LAHEY HOSPITAL & MEDICAL CENTER ("LHMC"). THE SYSTEM OPERATIONALIZED MULTIPLE DRIVE-THROUGH COVID-19 TESTING SITES TO ENABLE EASY ACCESS FOR PATIENTS AND STAFF.

BILH'S VIRTUAL TRANSFER CENTER WAS FORMED IN SEPTEMBER 2019 TO OPTIMIZE SYSTEM-WIDE BED CAPACITY USING REAL-TIME INFORMATION EXCHANGE AMONG THE THREE EXISTING TRANSFER CENTERS AT BIDMC, LHMC AND MOUNT AUBURN HOSPITAL ("MAH"). THE TRANSFER TEAM PERSONNEL AT THESE CENTERS WORK TOGETHER AS A SINGLE "VIRTUAL" CENTER TO ACCOMMODATE INCOMING TRANSFER REQUESTS BY MAKING ALL BEDS AVAILABLE IN THE SYSTEM BASED ON FACILITY CAPACITY AND LEVEL OF CARE REQUIRED. THE TRANSFER CENTER ENHANCED PATIENT QUALITY, SAFETY, AND ACCESS BY LOAD BALANCING COVID PATIENTS ACROSS ALL OF ITS HOSPITALS SO THAT THESE PATIENTS RECEIVED TIMELY ACCESS TO THE TYPE OF BED AND LEVEL OF CARE NEEDED. BILH COLLABORATED WITH EXTERNAL ENTITIES TO STAND UP A 1,000-BED FIELD HOSPITAL, THE BOSTON HOPE HOSPITAL, AND OPEN AND STAFF A COVID HOTEL FOR UNDERSERVED COMMUNITIES. BILH LAUNCHED A WEBSITE TITLED THE CORONAVIRUS RESOURCE CENTER TO PROVIDE ITS PATIENT COMMUNITY WITH UP-TO-DATE INFORMATION REGARDING THE SYSTEM'S RESPONSE TO THE PANDEMIC, AVAILABLE RESOURCES SUCH AS TESTING SITES, AND INNOVATION EFFORTS UNDERWAY THROUGHOUT BILH (E.G., VAPORIZED HYDROGEN PEROXIDE STERILIZATION FOR N95 RESPIRATORS).

IN LATE MARCH 2020 BILH CREATED HOUSING FOR QUARANTINE OF STAFF EXPOSED TO COVID-19. HOUSING WAS SET UP AT A LOCAL UNIVERSITY AND HOTELS COVERING THE NETWORK'S SERVICE AREA. APPROXIMATELY 300 STAFF MEMBERS TOOK ADVANTAGE OF THE HOUSING FROM MARCH TO JULY 2020. IN ADDITION TO HOUSING, FOOD AND SUPPLY DELIVERY SERVICES WERE CREATED TO MINIMIZE PUBLIC CONTACT. BILH COLLABORATED REGULARLY WITH COMMUNITY HEALTH CENTER ("CHC") AFFILIATES ON COVID-RELATED CARE, TESTING, PERSONAL PROTECTIVE EQUIPMENT ("PPE"), AND PATIENT OUTREACH. BILH SHARED REAL-TIME ACCESS TO BILH COVID-19-RELATED OPERATIONAL POLICIES, PROCESSES, AND GUIDELINES IN ADDITION TO TRANSLATED PATIENT HANDOUTS, FLYERS, AND SOCIAL MEDIA GRAPHICS AROUND THE "STOP THE SPREAD" CAMPAIGN. AS HEALTH CENTERS WORKED TO ESTABLISH STABLE SUPPLY CHAINS OF PPE, BILH DONATED GLOVES, N95S, ISOLATION GOWNS, DISINFECTANT WIPES, EYE PROTECTION, HAND SANITIZER, AND SURGICAL MASKS. BILH DEPLOYED STAFF AT COMMUNITY TESTING SITES SUCH AS AT THE DIMOCK CENTER. CHC STAFF WERE INCLUDED IN THE AFOREMENTIONED BILH-FUNDED TEMPORARY HOUSING PROGRAM FOR STAFF.
