We'd love to have GiveWell evaluate Watsi. They often recommend global health interventions because every dollar goes incredibly far in saving lives. In the meantime, here's what a few (independent) experts have said about investing in access to surgery:
• A review across 23 LMICs found that low-complexity surgeries (e.g., appendectomy, hernia repair) cost as little as $17 per Disability-Adjusted Life Year (DALY) averted (Mengistie et al., 2025). Overall, 89% of surgical procedures studied were cost-effective, and 76% were “very cost-effective” based on GDP thresholds (Ifeanyichi et al., 2024).
• Essential surgery often achieves costs per DALY well below standard willingness-to-pay thresholds and can be more valuable than essential drugs or vaccines on a per-DALY basis (Mengistie et al., 2025). Low-complexity surgical interventions compare favorably to—and are sometimes more cost-effective than—interventions such as HIV antiretroviral therapy, family planning, and TB vaccinations (Ifeanyichi et al., 2024).
