OBJECTIVE: When extremely premature birth at the limits of viability is imminent, shared decision-making with parents regarding the infant's treatment is widely recommended. Aligning decisions with parental values can be challenging. So, this study aims to get insight into (1) what values parents considered important in their decision, (2) whether their decision was based on intuition and/or rational analysis and (3) parental suggestions on how to help explore and articulate values during prenatal counselling. DESIGN: A qualitative study was performed among Dutch parents who experienced (imminent) extremely premature birth. Diversity was aimed for through purposive sampling. Semistructured interviews were conducted until saturation was achieved. Transcripts were coded and themes were derived from the data. RESULTS: Nineteen interviews were performed. Results show what parents considered important in their decision, such as the infants' future, family life and 'giving a chance'. Most parents made their decision more intuitively rather than rationally, for others both coexisted. Particularly fathers and parents who opted for palliative comfort care experienced the decision as rational. Parents would have liked to explore values, but found it challenging. They suggested strategies and conditions to help explore and articulate their values during counselling, such as a multidisciplinary approach. CONCLUSIONS: Various considerations and underlying values were found to be important. Parents recognise the influence of emotions and intuition in decision-making and struggle to articulate their values, emphasising the need for guidance. Healthcare providers should engage in open, personalised discussions to facilitate value exploration, enabling informed decisions aligned with parental values.
