Left digit bias in selection and acceptance of deceased donor organs

Organs suitable for donation are a scarce resource and maximizing the use of available organs is a priority. We aimed to determine whether there is a supply restricting left digit bias in organs offered and accepted for donors entering a new decade of age.

Potential deceased organ donors (n = 105,387) who had any organs offered for transplantation from 2010 to 2019 Organ Procurement and Transplantation Network data were analyzed. Donors were identified 1 year before and after a decade altering birthday.

At age 70 there was a 5.4% decrease in the probability of any organ placement compared to 69 (95% CI 1.1-9.7). There was a decrease of 0.25 organs (95% CI 0.13-0.37) after age 70.

There was a significant left digit bias in the acceptance of any organs for transplantation at ages 60 and 70 as well as in the acceptance of a kidney at age 70.
