Group 1 | Conditions for which treatment with curative intention is feasible but might fail, e.g., cancer or irreversible organ failure. |
Group 2 | Conditions for which there are long periods of intensive treatment aimed at prolonging good-quality life but for which premature death is anticipated, e.g., cystic fibrosis, muscular dystrophy. |
Group 3 | Progressive condition where treatment is exclusively palliative from the time of diagnosis and may extend over many years, e.g., metabolic disorders. |
Group 4 | Conditions with severe disability, often neurological, which although not progressive cause extreme vulnerability to health complications and where premature death is anticipated, e.g., severe cerebral palsy, chromosomal disorders. |
