Table 1.

Categories of life-limiting and life-threatening conditions [9].

Category 1	Those children with life-threatening conditions for which curative treatment may be feasible but can fail. e.g., cancer, irreversible organ failure
Category 2	Those children with conditions in which there may be long phases of intensive treatment aimed at prolonging life, but premature death is still possible e.g., cystic fibrosis, Duchenne muscular dystrophy
Category 3	Those children with progressive conditions without curative treatment. e.g., batten disease, mucopolysaccharidoses
Category 4	Those children with conditions with severe neurological disability, which may deteriorate unpredictably, but are not considered progressive.
