^aAdjusted for both group membership and trajectory covariates. Group membership covariates included age at enrolment, marital status, preferred plan of care, awareness of diagnosis/prognosis by patient/family, medical subsidy means testing, primary decision maker, living arrangement, primary cancer diagnosis, Charlson Comorbidity Index, and ECOG performance status. Trajectory covariates included presence of unstable physical symptoms, presence of distressing psychosocial symptoms, and at least 4 HCA physical visitations per bi-week
