Background: Being able to visit a critically ill relative provides comfort to family members and has recognised benefits to the patient. Limited research has been conducted on demographic characteristics and visiting behaviours of family members with a relative in the intensive care unit (ICU). Objectives: The objective was to provide an overview of local ICU visitor behaviours and practices across four metropolitan units in Australia. Methods: A convenience sample of 440 participants from four ICUs across a metropolitan city in eastern Australia was required for the study. A descriptive 22-item self-report survey was used. Data were collected from four ICUs in a metropolitan city in eastern Australia. Sample characteristics and other variables were analysed using descriptive statistics. Results: Data collection was undertaken from April 2018 to May 2019. Four hundred sixty-two (n = 462) ICU visitors responded. There were no significant differences between visitor characteristics across the four hospitals. The mean age of the respondents was 49 years, the youngest participant being 18 years and the oldest being 93 years, with most visitors being women (n = 312, 68%). The participants were more likely to be close relatives such as spouses (n = 117, 25%), parents (n = 113, 24%), or children (n = 79, 17%). Visitors reported different methods by which they received information about visiting policies across units and indicated that they would have visited more frequently if able. Although most respondents rated their ICU visiting experience favourably, some reported being frequently asked to leave the patient's bedside impacted their experience. Conclusions: This study has highlighted that families want to remain in close proximity when they have a relative in the ICU. Despite visiting hours being flexible, most families visit midmorning so that they can talk with staff. Data captured in this study can be used toward improving the ICU visiting experience for family members.
