Frequent visiting and communication with patients' families are embedded within normal ICU practice, however the COVID-19 pandemic has challenged this, and it is unclear how ICUs are managing. We aimed to investigate how NHS ICUs are approaching family communications and visiting during the COVID-19 pandemic. An electronic snapshot survey was delivered between 16th April and 4th May 2020 and was open to NHS ICUs. Replies from 134 individual ICUs with COVID patients were included. All reported that visiting was more restricted than normal with 29 (22%) not allowing any visitors, 71 (53%) allowing visitors at the end of a patient's life (EOL) only, and 30 (22%) allowing visitors for vulnerable patients or EOL. Nearly all (n = 130, 97%) were updating families daily, with most initiating the update (n = 120, 92%). Daily telephone calls were routinely made by the medical (n = 75, 55%) or nursing team (n = 50, 37%). Video calling was used by 63 (47%), and 39 (29%) ICUs had developed a dedicated family communication team. Resuscitation and EOL discussions were most frequently via telephone (n = 129, 96%), with 24 (18%) having used video calling, and 15 (11%) reporting discussions had occurred in person. Clinicians expressed their dissatisfaction with the situation and raised concerns about the detrimental effect on patients, families, and staff. COVID-19 has resulted in significant changes across NHS ICUs in how they interact with families. Many units are adapting and moving toward distant and technology-assisted communication. Despite innovative solutions, challenges remain and there may be a role for local and national guidance.
