IN ADDITION TO THE PROGRAM SERVICE ACCOMPLISHMENTS NOTED ABOVE, THE BILH NETWORK HAD SIGNIFICANT ACTIVITIES ACROSS ENTITIES RELATED TO BOTH BEHAVIORAL HEALTH AND ITS RESPONSE TO THE ONGOING COVID-19 PANDEMIC. DETAILS ON BOTH ARE BELOW THE BETH ISRAEL LAHEY HEALTH NETWORK (BILH) IS COMMITTED TO THE BEHAVIORAL HEALTH NEEDS OF THE PATIENTS AND COMMUNITIES SERVICED. BELOW ARE SOME OF ACTIVITIES THAT BILH BEHAVIORAL SERVICES (BILHBS) HAS PROVIDED TO THE PATIENTS AND COMMUNITIES SERVED BY BILH AND ITS AFFILIATED ENTITIES. BILHBS (WHICH INCLUDES THE ACTIVITIES OF BILH'S TAX-EXEMPT AFFILIATE NORTHEAST BEHAVIORAL HEALTH CORP) IS THE LARGEST NETWORK OF MENTAL HEALTH AND SUBSTANCE USE DISORDER SERVICES IN EASTERN MASSACHUSETTS. BILHBS' NETWORK OF BEHAVIORAL HEALTH CARE INCLUDES SERVICES FOR CHILDREN AND ADULTS RANGING FROM INPATIENT TREATMENT TO COMMUNITY-BASED PROGRAMS. SERVICES INCLUDE: INPATIENT PSYCHIATRIC AND DETOXIFICATION TREATMENT; EMERGENCY PSYCHIATRIC AND MOBILE EMERGENCY SERVICES TEAMS; OUTPATIENT MENTAL HEALTH AND ADDICTION TREATMENT; INDIVIDUAL/COUPLE/FAMILY THERAPY; MEDICATION ASSISTED TREATMENT PROGRAMS FOR PERSONS WITH OPIOID USE DISORDERS; AND SCHOOL-BASED AND HOME-BASED COUNSELING FOR YOUTH AND THEIR FAMILIES. SINCE THE CREATION OF BILH IN MARCH 2019, BILH HAS INVESTED SIGNIFICANTLY IN IMPROVING ACCESS TO BEHAVIORAL HEALTH CARE THROUGH A SYSTEM-WIDE APPROACH TO CARE DELIVERY. FIRST, IT HAS MADE A MULTI-YEAR COMMITMENT TO PROVIDE BEHAVIORAL HEALTH SUPPORT TO ITS EMPLOYED PRIMARY CARE PRACTICES USING AN EVIDENCE-BASED APPROACH KNOWN AS THE IMPACT MODEL. BY THE END OF FY 2021, BILH HAD IMPLEMENTED THE IMPACT MODEL IN 67% OF ITS EMPLOYED PRIMARY CARE PRACTICES AS PART OF ITS COLLABORATIVE CARE PROGRAM IMPLEMENTATION. IN 2021, BILHBS EXPANDED ITS PRIMARY CARE BEHAVIORAL HEALTH INTEGRATION (PCBHI) SERVICES BY INCORPORATING A DSRIP PILOT PROJECT AIMED AT INTERPROFESSIONAL PSYCHIATRIC CONSULTS. THE PCBHI INTERPROFESSIONAL CONSULTATION INCLUDES AN ASSESSMENT AND MANAGEMENT SERVICE IN WHICH A PATIENT'S PRIMARY CARE PROVIDER (PCP) REQUESTS THE OPINION AND/OR TREATMENT ADVICE OF A PSYCHIATRIC CONSULTANT TO ASSIST IN THE DIAGNOSIS AND/OR MANAGEMENT OF THE PATIENT'S BEHAVIORAL HEALTH CONDITION WITHOUT THE NEED FOR THE PATIENT'S FACE-TO-FACE CONTACT WITH THE CONSULTANT. INTERPROFESSIONAL CONSULTATION ENABLES A COMPREHENSIVE ASSESSMENT, ENHANCES PATIENT CARE, REDUCES MISDIAGNOSIS, AND SUPPORTS THE INTEGRATION OF DISCIPLINES IN THE DELIVERY OF CARE. THE PCBHI INTERPROFESSIONAL PSYCHIATRIC CONSULTANTS PROVIDE PCPS WITH ANOTHER AVENUE FOR INTEGRATED CARE. THE IMPLEMENTATION OF PCBHI INTERPROFESSIONAL SERVICES WILL BE OFFERED IN PRACTICES WHERE COLLABORATIVE CARE IS NOT CURRENTLY AVAILABLE. ADDITIONALLY, IN 2021, BILHBS CONTINUED TO OVERSEE THE BILH-WIDE CENTRALIZED BEHAVIORAL HEALTH (BH) BED MANAGEMENT, WHICH SUPPORTS INPATIENT BEHAVIORAL HEALTH BED CAPACITY AND IMPROVING ACCESS TO THESE BEDS, WITH THE PARALLEL GOAL OF REDUCING BOARDING BY BEHAVIORAL HEALTH PATIENTS IN THE EMERGENCY DEPARTMENTS ("EDS"). AS PART OF THE CENTRALIZED BH BED MANAGEMENT, BILH STAFF ENGAGE IN A DAILY HUDDLE WITH REPRESENTATIVES FROM BILH HOSPITALS' EDS AND BEHAVIORAL HEALTH UNITS TO DISCUSS PATIENTS APPROPRIATE FOR TRANSFER TO THE UNIT. THE DAILY HUDDLES HAVE BECOME A FORUM FOR WHICH PARTICIPANTS DISCUSS BEHAVIORAL HEALTH PATIENT VOLUME AND BED CAPACITY ACROSS THE SYSTEM, AS WELL AS DISCHARGE PLANNING AND PLACEMENT OPPORTUNITIES FOR DIFFICULT-TO-PLACE PATIENTS. SEPARATELY, IN MARCH 2021, BILHBS LAUNCHED ITS CENTRALIZED BED FINDING TEAM. THIS TEAM IS PART OF OUR CENTRAL CALL CENTER, WHICH CENTRALIZES CALLS TO BILHBS' THREE EMERGENCY SERVICE PROGRAM (ESP) CATCHMENT AREAS REDUCING REDUNDANCIES ACROSS THE AGENCY AND STREAMLINING ALL CALLS TO ONE CENTRAL SERVICE. THIS CENTRALIZED BED FINDING TEAM IS RESPONSIBLE FOR CONDUCTING BED SEARCHES FOR PATIENTS SEEN THROUGH THE ESP AND WHO ARE AWAITING AN INPATIENT PSYCHIATRIC PLACEMENT. THIS TEAM DIRECTLY INCREASES THE AVAILABILITY OF CLINICIANS TO CONTINUE TO SEE PATIENTS IN THE ED AND THE COMMUNITY WHO ARE EXPERIENCING A BEHAVIORAL HEALTH AND/OR CO-OCCURRING SUBSTANCE USE DISORDER CRISIS WHILE OTHER TEAM MEMBERS SEARCH FOR AVAILABLE INPATIENT PLACEMENTS. THIS INITIATIVE SUPPORTS DECREASED RESPONSE TIME TO RESPONDING TO NEW PATIENTS IN CRISIS AND REDUCES ED BOARDING TIME FOR PATIENTS WHO CAN BE SAFELY MANAGED IN THE COMMUNITY. BILHBS SERVES APPROXIMATELY 35,000 UNDUPLICATED INDIVIDUALS ANNUALLY, OFFERING A FULL CONTINUUM OF CARE FOR CHILDREN AND ADULTS. SERVICES RANGE FROM INPATIENT TO HOME AND COMMUNITY-BASED SERVICES. BILHBS OPERATES OVER 250 BEDS IN 9 FACILITIES FOR CLIENTS REQUIRING ACUTE PSYCHIATRIC CARE, DETOXIFICATION AND RESIDENTIAL STEP-DOWN SERVICES. DURING THE PERIOD COVERED BY THIS FILING, COMMUNITY-BASED SERVICES INCLUDED MOBILE EMERGENCY SERVICES TEAMS IN THREE CATCHMENT AREAS AND HOME-BASED COUNSELING FOR ADULTS, YOUTH AND THEIR FAMILIES. BILHBS ALSO PROVIDED SERVICES IN 63 MIDDLE AND HIGH SCHOOLS, AS WELL AS 9 POLICE DEPARTMENTS. BILHBS ALSO CONTINUES TO IMPROVE ACCESS THROUGH THE URGENT PSYCHOPHARMACOLOGY SERVICES IN BILH'S LOWELL EMERGENCY SERVICES PROGRAM. THIS CLINIC PROVIDES URGENT ACCESS FOR PATIENTS REQUIRING A CHANGE TO THEIR MEDICATIONS. THIS SERVICE IS OFFERED 20 HOURS PER WEEK AND INCLUDES UNINSURED, MEDICAID, AND MEDICARE POPULATIONS, AS WELL AS ANY PERSON IN NEED OF THE SERVICE REGARDLESS OF THE PAYER SOURCE. BILH'S COMMUNITY CRISIS STABILIZATION ("CCS") UNITS IN LAWRENCE AND SALEM, WHICH TYPICALLY CARE FOR PATIENTS WITH MENTAL HEALTH ISSUES, INCREASED THEIR ABILITY TO TREAT PERSONS WITH CO-OCCURRING SUBSTANCE USE DISORDERS. THE CCS UNITS CONTINUE TO BE ABLE TO INDUCT PATIENTS WITH OPIOID USE DISORDER (OUD) ON BUPRENORPHINE AND ARE ALSO ABLE TO MAINTAIN PATIENTS WHO ARE ALREADY ON ANY OF THE THREE FDA APPROVED MEDICATIONS FOR THE TREATMENT OF OUD. THESE UNITS ARE SEEING AN INCREASE IN THE NUMBER OF PATIENTS WITH METHAMPHETAMINE DISORDERS AND HAVE DEVELOPED A PROTOCOL TO MANAGE WITHDRAWAL SYMPTOMS IN THIS POPULATION. BILHBS CONTINUES TO MAINTAIN AND ENHANCE ITS TELEHEALTH PLATFORM AND CLINICAL DELIVERY THROUGH THE USE OF DIGITAL APPLICATIONS ACROSS ALL OF ITS AMBULATORY PROGRAMS. SPECIAL EMPHASIS WAS PLACED ON SPANISH-LANGUAGE ACCESS TO LAWRENCE-BASED PROGRAMS TO ENSURE PATIENTS IN THIS REGION ACCESS LINGUISTICALLY-APPROPRIATE CARE. IN 2021, BILHBS IDENTIFIED IMPROVEMENT OF THE PATIENT EXPERIENCE AS A KEY STRATEGIC PRIORITY. TO THAT END, ALL PROGRAM DIRECTORS ARE EVALUATED AGAINST THIS GOAL AND ARE REQUIRED TO COMPLETE TWO PLAN-DO-STUDY-ACT (PDSA) CYCLES ANNUALLY. PDSA IS A WELL-ESTABLISHED PROCESS IMPROVEMENT FRAMEWORK USED IN HEALTHCARE. PROGRAM DIRECTORS REVIEW PATIENT FEEDBACK TO DEVELOP PILOT INTERVENTIONS, ANALYZE THE RESULTS, AND THEN MAKE ADJUSTMENTS TO THE INTERVENTION. EXAMPLES OF OUTCOMES ACHIEVED THROUGH THE PDSA APPROACH INCLUDE ENHANCING THE PATIENT ENGAGEMENT MODEL FOR THE BEHAVIORAL HEALTH COMMUNITY PARTNERS (BHCP) PROGRAM; IMPROVING PATIENT EXPERIENCES AND ENGAGEMENT IN THE USE OF TELEHEALTH PLATFORMS IN BILHBS' LAWRENCE OUTPATIENT SITE, IMPROVING THE ADMISSION PROCESS IN THE BILHBS GLOUCESTER OPIOID TREATMENT CENTER, REDUCING ADMINISTRATIVE DISCHARGES BY IMPLEMENTING A HARM REDUCTION MODEL, AND IMPROVING EXTERNAL REFERRAL EXPERIENCE AT THE BILHBS HAVERHILL OUTPATIENT AND CHILDREN'S BEHAVIORAL HEALTH INITIATIVES (CBHI) PROGRAMS.
BETH ISRAEL LAHEY HEALTH'S COVID-19 PANDEMIC RESPONSE	AS IN THE PRIOR YEAR, BETH ISRAEL LAHEY HEALTH'S ("BILH") HOSPITALS AND OTHER PATIENT CARE ORGANIZATIONS EXPENDED SIGNIFICANT TIME AND RESOURCES ACROSS FY 2021 IN THEIR CONTINUED EFFORTS TO RESPOND TO THE COVID-19 PANDEMIC. IN ADDITION TO PROVIDING COVID-19 TESTING AND TREATMENT, THE HEALTH SYSTEM INITIATED PATIENT AND STAFF VACCINATION EFFORTS IN FY 2021, REACHING OUT TO 1.3 MILLION PATIENTS USING A MULTICHANNEL, MULTILINGUAL APPROACH AND ULTIMATELY DELIVERING OVER 400,000 VACCINE DOSES. THE SYSTEM SUCCESSFULLY UNDERTOOK THESE EFFORTS WHILE ALSO NAVIGATING UNPRECEDENTED FINANCIAL AND OPERATIONAL CHALLENGES STEMMING FROM THE PANDEMIC, INCLUDING ONGOING WORKFORCE DISRUPTION AND A DECLINE IN PATIENT VOLUME DUE TO THE CURTAILMENT OF ELECTIVE SERVICES AND STAFFING CHALLENGES. HIGHLIGHTS OF THE SYSTEM'S PANDEMIC RESPONSE IN FY 2021 INCLUDE: STAFF TESTING, VACCINATION, AND SUPPORT IN NOVEMBER 2020, BILH IMPLEMENTED A PROGRAM TO PROVIDE ITS 36,000 EMPLOYEES WITH ACCESS TO ONSITE, VOLUNTARY, AND FREE-OF-CHARGE COVID-19 PCR TESTING, EVEN IF THEY HAD NO KNOWN EXPOSURE OR SYMPTOMS. IN ADDITION TO SERVING AS AN IMPORTANT ELEMENT TO CONTAIN COMMUNITY SPREAD OF COVID-19, THIS EFFORT BOOSTED BILH STAFF MORALE AND CONFIDENCE DURING THIS CHALLENGING PERIOD. IN DECEMBER 2020, BILH STOOD UP STAFF VACCINATION SITES AT ITS LOCAL HOSPITALS, ULTIMATELY DELIVERING 70,000 VACCINE DOSES TO ITS WORKFORCE IN FY 2021. THE SYSTEM TOOK PROGRESSIVE MEASURES AROUND EMPLOYEE PAID TIME OFF TO SUPPORT VACCINATION EFFORTS AS WELL AS FAMILY CARE NEEDS AND TIME MISSED DUE TO COVID-19 ILLNESS OR TESTING. IN THE SUMMER OF 2021, BILH COMMUNICATED THAT COVID-19 AND FLU VACCINE WOULD BE REQUIRED AS A CONDITION OF EMPLOYMENT; THE COVID-19 VACCINATION DEADLINE WAS SUCCESSFULLY COMPLETED ON OCTOBER 31, 2021. BILH OPERATIONALIZED A CENTRALIZED CALL CENTER TO SUPPORT STAFF WITH SYMPTOM REPORTING, COVID-19 TESTING, AND RETURN-TO-WORK PROCESSES. THE CALL CENTER ENSURED CONVENIENT AND ACCESSIBLE INFORMATION FOR A WORKFORCE SPREAD THROUGHOUT EASTERN MASSACHUSETTS. AT ITS PEAK, THE CENTRALIZED CALL CENTER HANDLED OVER 1,000 PHONE CALLS PER DAY. PATIENT VACCINATION NEARLY IMMEDIATELY UPON RECEIVING VACCINE SUPPLY THAT COULD BE USED FOR PATIENTS, BILH OPENED AND OPERATED 10 VACCINE ADMINISTRATION SITES ACROSS EASTERN MASSACHUSETTS. THE LOCATIONS WERE SELECTED BASED ON SEVERAL CRITERIA, INCLUDING PROXIMITY TO HARD-HIT COMMUNITIES AND EASE OF ACCESS IN TERMS OF TRANSPORTATION. THIS WAS A SIGNIFICANT LOGISTICAL FEAT IN LIGHT OF THE SHIFTING FORECASTS IN VACCINE SUPPLY AND SPECIAL HANDLING REQUIRED FOR THE PFIZER VACCINE. BILH DEVELOPED ITS OWN VACCINATION SCHEDULING TOOL, COVAX, TO SUPPORT STAFF AND PATIENT VACCINATION EFFORTS. THIS TOOL ENABLED BILH TO IDENTIFY PATIENTS ELIGIBLE FOR VACCINATION BASED ON STATE GUIDELINES, SCHEDULE APPOINTMENTS, AND TRACK VACCINATION ACTIVITY. BILH LED A TARGETED CAMPAIGN TO SUPPORT HEALTH EQUITY BY PRIORITIZING FOR VACCINATION BILH PATIENTS WHO RESIDED IN A COMMUNITY OR TOWN IDENTIFIED AS HAVING AMONG THE HIGHEST CUMULATIVE INCIDENCE OF COVID-19 WITHIN THE STATE OF MASSACHUSETTS. BILH ALSO COORDINATED WITH MULTIPLE COMMUNITY HEALTH CENTERS TO PROVIDE THEIR PATIENTS WITH PRIORITY ACCESS TO VACCINATION APPOINTMENTS. DUE TO THESE EFFORTS, BETH ISRAEL DEACONESS CARE ORGANIZATION ("BIDCO"), AN ACCOUNTABLE CARE ORGANIZATION ("ACO") WITHIN BILH, HAD THE HIGHEST COVID-19 VACCINATION RATE FOR MEDICAID MEMBERS AMONG ALL MEDICAID ACOS IN THE STATE. BILH ESTABLISHED THE COVID-19 HEALTH EQUITY ADVISORY COUNCIL ("THE COUNCIL") WITH A GOAL TO ADDRESS HEALTH DISPARITIES BROUGHT ON BY THE PANDEMIC, LANGUAGE BARRIERS, AND OTHER SOCIAL DETERMINANTS OF HEALTH. ITS MEMBERSHIP INCLUDED KEY BILH STAKEHOLDERS AND COMMUNITY HEALTH CENTER CHIEF MEDICAL OFFICERS. AS PART OF ITS RESPONSIBILITY, THE COUNCIL REVIEWED THE SYSTEM'S VACCINE ROLLOUT STRATEGY, INCLUDING THE PATIENT PRIORITIZATION AND SCHEDULING STRATEGY, CALL CENTER MODEL, VACCINE SITE LOCATION AND OPERATING MODEL, AND STAFF RESOURCES TO HELP COMMUNICATE AND ENGAGE WITH PATIENTS ABOUT VACCINE INFORMATION, CONCERNS, AND HESITANCY. TESTING IN FY 2021, BILH PERFORMED OVER 600,000 COVID-19 TESTS ACROSS ITS 10 HOSPITAL LABORATORIES FOR PATIENTS, HEALTHCARE PERSONNEL, AND OTHER PARTNERS, SUCH AS COMMUNITY HEALTH CENTERS AND CORRECTIONAL FACILITIES. IN JANUARY 2021, LAHEY HOSPITAL & MEDICAL CENTER BEGAN TESTING ON HIGH-THROUGHPUT THERMO FISHER INSTRUMENTS, GREATLY INCREASING THE SYSTEM'S CAPACITY FOR SAME-DAY TEST RESULTS.

THROUGHOUT FY 2021, BILH INFECTION PREVENTION DEVELOPED AND UPDATED CLINICAL AND OPERATIONAL GUIDANCE INCLUDING POLICIES, TOOLS, AND EDUCATIONAL MATERIALS TO SUPPORT THE PREVENTION OF TRANSMISSION OF COVID-19.

TREATMENT BILH HOSPITALS CONTINUED TO PROVIDE TREATMENT TO ADMITTED PATIENTS WITH COVID-19, USING TREATMENTS AUTHORIZED FOR USE AT THE TIME. LEADERS ACROSS BILH HOSPITALS CONTINUED TO MEET AND SHARE INFORMATION TO ALLOW FOR APPROPRIATE RESOURCE ALLOCATION AND LOAD BALANCING TO ENSURE BILH WAS ABLE TO MEET PATIENT DEMAND. IN FY 2021, BILH BEGAN TO MAKE AVAILABLE TO AMBULATORY PATIENTS COVID-19 THERAPEUTICS (INTRAVENOUS MONOCLONAL ANTIBODIES AND REMDESEVIR) AND PROPHYLAXIS (EVUSHELD), WITH THESE EFFORTS EXPANDING ACROSS 2022.

UNDERPINNING THESE MANY INITIATIVES WERE VARIOUS MULTI-ENTITY, INTERDISCIPLINARY COMMITTEES AND DATA COLLECTION EFFORTS TO ENSURE THAT BILH WAS PROACTIVELY MONITORING THE TRAJECTORY OF THE PANDEMIC AND NIMBLY PLANNING THE SYSTEM'S RESPONSE. THE HEALTH SYSTEM'S EFFORTS SPANNED THE CLINICAL CARE CONTINUUM, FROM PRIMARY CARE TO POST-ACUTE CARE, AS WELL AS BOTH CLINICAL AND ADMINISTRATIVE DEPARTMENTS, FROM INFECTIOUS DISEASE AND NURSING TO HUMAN RESOURCES AND INFORMATION SERVICES. BILH SUCCESSFULLY MARSHALLED ITS RESOURCES THROUGHOUT THE SYSTEM TO SERVE AS ONE OF THE PRIMARY HUBS FOR COVID-19 RELATED CARE IN MASSACHUSETTS.
