Clusters in hospitals, long-term care facilities, and other entities licensed by the Division of Healthcare Quality (DHCQ), should also be reported to DHCQ by using the web-based Health Care Facility Reporting System (HCFRS), via the Virtual Gateway. All Reportable Assisted Living Incident Reports are submitted to the Executive Office of Elder Affairs via the Automated Quickbase Reporting system. Group homes, correctional facilities, or other settings should also contact the appropriate oversight agency for your facility.
