To evaluate parental perception of advance care plan (ACP) discussions in families of Malaysian children with bilateral cerebral palsy (CP) classified in Gross Motor Function Classification System levels IV or V for (1) acceptance of the ACP discussion, (2) feedback on the usefulness of ACP discussion, and (3) exploration of possible factors related to parental acceptance of ACP. Method: This was a prospective pre-and post-ACP discussion questionnaire study for parents of children with bilateral CP.Results: Sixty-nine patients were recruited to the study; 64 (93%) had at least one additional comorbidity. The median age was 8 years (interquartile range 5 years 1 month-11 years 6 months). Fifty-seven (82.6%) parents found the ACP discussion acceptable, and most reported positive feedback on various components of the discussion (88.4-97.1%). One-third of participants were not comfortable discussing end-of-life care plans. On multivariate analysis, parents who were comfortable discussing end-of-life care plans were more likely to find the ACP discussion acceptable (odds ratio 27.78, 95% confidence interval 2.9-265.1, p = 0.004).Interpretation: Most parents of Malaysian children with bilateral CP reported the ACP discussion as both acceptable and beneficial. Parents need to be comfortable about discussing end-of-life care plans for their child to enable the ACP discussion to be an acceptable experience.
