BackgroundThe vegetative state (VS) after severe acute brain injury (SABI) is associated with significant prognostic uncertainty and poor long-term functional outcomes. However, it is generally distinguished from imminent death and is exempt from the Life-Sustaining Treatment (LST) Decisions Act in Korea. Here, we aimed to examine the perspectives of the general population (GP) and clinicians regarding decisions on mechanical ventilator withdrawal in patients in a VS after SABI.MethodsA cross-sectional survey was undertaken, utilizing a self-reported online questionnaire based on a case vignette. Nationally selected by quota sampling, the GP comprised 500 individuals aged 20 to 69 years. There were 200 doctors from a tertiary university hospital in the clinician sample. Participants were asked what they thought about mechanical ventilator withdrawal in patients in VS 2 months and 3 years after SABI.ResultsTwo months after SABI in the case, 79% of the GP and 83.5% of clinicians had positive attitudes toward mechanical ventilator withdrawal. In the GP, attitudes were associated with spirituality, household income, religion, the number of household members. On the other hand, clinicians' attitudes were related to their experience of completing advance directives (AD) and making decisions about LST. In this case, 3 years after SABI, 92% of the GP and 94% of clinicians were more accepting of ventilator withdrawal compared to previous responses, based on the assumption that the patient had written AD. However, it appeared that the proportion of positive responses to ventilator withdrawal decreased when the patients had only verbal expressions (82% of the GP; 75.5% of clinicians) or had not previously expressed an opinion regarding LST (58% of the GP; 39.5% of clinicians).ConclusionMore than three quarters of both the GP and clinicians had positive opinions regarding ventilator withdrawal in patients in a VS after SABI, which was reinforced with time and the presence of AD. Legislative adjustments are needed to ensure that previous wishes for those patients are more respected and reflected in treatment decisions.© 2024 The Korean Academy of Medical Sciences.
