“…However, this limited research reveals that formal support systems are inadequate [ 5 , 16 , 18 , 22 , 54 ] despite the multiple service providers involved in the lives of people with SPMI [ 14 , 17 , 51 ]. Furthermore, even though mental health, NDIS, and palliative care providers share person-centred values [ 15 , 19 , 40 , 92 , 93 ], collaboration between providers, though highly recommended and encouraged, is poor, limited or non-existent [ 15 , 16 , 18 , 21 , 22 , 27 , 38 , 40 , 53 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 ]. The NDIS does not fund case management or care coordination, a recognised and highly valued role in mental health systems [ 100 , 101 ], to the detriment of NDIS participants with complex support needs.…”
