Aim: To analyze the Ukrainian and international experience of HF communications in ES to identify effective solutions that can be implemented in Ukraine in order to increase the readiness of HF to function in crisis conditions and improve interaction with key partners. Materials and Methods: A survey of 870 managers and employees from 45 healthcare facilities in different regions of Ukraine was conducted to assess the level of management during emergencies. The author’s questionnaire was developed taking into account the World Health Organization (WHO) recommendations on crisis communication. The survey was conducted in April–May 2025 remotely, in compliance with the principles of volunteerism, anonymity and bioethics (informed consent, confidentiality, prevention of harm). The instrument has been initially tested and has not been used in other studies, which confirms its novelty. Results: The results of the self-assessment of internal communication effectiveness show that 51% of respondents assessed communication as “rather effective, indicating a basic level of functioning with potential for improvement. Additionally, 62,2% of respondents indicated that their facilities have internal commu nication protocols in place that are regularly updated, suggesting institutional maturity and a systematic approach to risk management. However, only 20% of healthcare facilities conduct crisis communication training regularly, which is a critically low figure under martial law. Most hospitals coordinate their actions with local authorities (77,8%), other healthcare facilities (60%), and emergency services and police (57,8%). Only 17,8% of healthcare facilities reported active coordination with the Ministry of Health of Ukraine, and even fewer with international humanitarian organizations (6,7%) and non-state partners (8,9%). Conclusions: The communication function in Ukrainian healthcare is not sufficiently institutionalized. WHO principles on communication in emergencies are only partially integrated and implemented in a fragmented manner. Personnel training in strategic communication is irregular, and coordination across management levels is weak. The military context further complicates the situation.
