Cost-effectiveness of donating a kidney

Summary

  • The cost-effectiveness of donating a kidney is about 0.7 QALY/​k$ to 20 QALY/​k$.

  • The cost-effectiveness of donating to GiveWell’s Maximum Impact Fund is about 10 QALY/​k$.

  • Donating a kidney is about 6 % to 100 % as cost-effective as donating to GiveWell’s Maximum Impact Fund.

    • Note that this comparison is often unfair, as suggested in this comment, since donating to effective charities and donating a kidney are usually not mutually exclusive.

The data and calculations are presented below.

Data

  • Benefits of donatig a kidney (BK): 14 QALY.

  • Cost of donating a kidney (CKL to CKH): 877 $ to 19,887 $.

  • Global GDP per capita in 2020 (GDPpC): 10.9 k$.

  • Cost-effectiveness of donating to GiveDirectly in units of doubling consumption[1] (CEGDU): 3.35 U/​k$.

  • Ratio between the cost-effectiveness of donating to GiveWell’s Maximum Impact Fund and to GiveDirectly[2] (RMIFGD): 8.

  • Value of health in units of doubling consumption[3] (HU): 2.3 U/​QALY.

Calculations

  • Cost of donating a kidney (CK): (CKL * CKH)^0.5 = 4.18 k$.

  • Cost-effectiveness of donating a kidney (CEKL to CEKH): BK /​ CKH = 0.704 QALY/​k$ to BK /​ CKL = 16.0 QALY/​k$.

  • Cost-effectiveness of donating to GiveDirectly (CEGD): CEGDU /​ HU = 1.46 QALY/​k$.

  • Cost-effectiveness of donating to GiveWell’s Maximum Impact Fund[4] (CEMIF): RMIFGD * CEGD = 11.7 QALY/​k$.

  • Ratio between the cost-effectiveness of donating a kidney and donating to GiveWell’s Maximum Impact Fund (RL to RH): CEKL /​ CEMIF = 6.04 % to CEKH /​ CEMIF = 137 %.

    To be precise, units of doubling consumption for one person for one year.

    “To this point, we’ve typically[8] funded opportunities that pass a relatively high bar: eight (or more) times as cost-effective as GiveDirectly”.

  3. ^

    In the cited report from GiveWell, 2.3 refers to the “value of averting one year of life lived with disease/​disability (YLD)”. This corresponds to the value of averting 1 DALY, which is assumed here to be equivalent to the value of creating 1 QALY.

    Note that the EA Global Health and Development Fund “recommends grants to GiveWell top charities as a baseline, but will recommend higher-risk grants they believe to be more effective (in expectation) than GiveWell top charities”.
