BICSI 004-2018. Information Technology Systems Design and Implementation Best Practices for Healthcare Institutions and Facilities While smart hospitals, the fusion intelligent building, IoT, and big data are still few and far between, today's healthcare facility is increasingly digitized, from health records, diagnostic and monitoring equipment, environmental controls far beyond the thermostat - even the routing office visit may be an remote interaction spanning thousands of miles. While the mission within healthcare remains the same, about the only constant in today's systems is the pace of technological advancement. And as more systems connect to the network, any ICT infrastrucutre deployed is not only required to meet today's needs, but those of tomorrow with minimal to no effect on the overall healthcare mission To address this need, ANSIBICSI 004-2018 has been revised and expanded for: Communication, ICT and wireless infrastructure, Architectural aspects of healthcare facilities, including telemedicine and communication suites, Emergency medical services radio, sound and acoustical systems, sound masking, and digital signage and wayfinding, Network design and security, and Other facets of smaller systems and spaces. And as healthcare has grown as a global concern, BICSI 004 was revised with the same global focus, incorporating technological standards and known operational differences where applicable, allowing for use in any locale.
