CARI Guidelines

Availability of resources should not be a reason to

deny a patient access onto dialysis.

Decisions to recommend or not to recommend dialysis should not be influenced by either availability

of resources or potential litigation.

Factors that impact dialysis initiation

•  GDP per capita •  Percentage of GDP spent on health care •  Dialysis reimbursement rate •  Private for-profit share of dialysis

provision •  Fragmentation of healthcare services •  Renal unit distribution •  Workforce availability


Factors that affect numbers on dialysis

•  Expanding insurance coverage •  Presence of CKD care plan •  Rationing policies •  Choice of dialysis modality (HD v PD) •  Incremental dialysis •  Advance care planning

Gaps in dialysis initiation


Conclusions

•  There is a large (and increasing) unmet global need of dialysis

•  Determinants of dialysis initiation are largely non-medical

•  Removal of financial barrier increases uptake/initiation on dialysis

•  Insurance coverage does not remove all barriers to long-term care

•  Residual inequities around dialysis initiation need addressing
