End-of-life decision-making is a complex process and more challenging when decisions are made for others. Little is known about Thai family members' involvement in decision-making to withdraw life-sustaining treatments (LSTs) from loved ones with serious illnesses. This qualitative study explores the experiences of family caregivers in Southern Thailand regarding decisions related to LST withdrawal. In-depth interviews were used to gather data from fifteen primary caregivers, who were involved in LST withdrawal decision-making. Content analysis was applied, and several techniques, such as member-checking and peer debriefing, were used to enhance trustworthiness. Four main themes were identified: facing dilemmas, weighing up options, making a consensual decision, and accepting the reality of life. The findings pointed out the significant roles played by family meetings and early end-of-life discussion in the process of decision-making to withdraw LSTs from loved ones. Further research on communication among patients' family members and health care providers is recommended.
