US Medical Colleges End<br />

Animal Laboratory Practice<br />

By Benjamin Goodin<br />

Recently, a momentous event quietly transpired as many of us<br />

were preparing to celebrate our country’s independence. In<br />

late June, just weeks after the medical school at Johns Hopkins<br />

University made a similar decision, the University of Tennessee<br />

discontinued the use of live animal laboratories in its medical school.<br />

With the end of this final program, live animal laboratories are officially<br />

no longer required at any American or Canadian medical schools.<br />

Live animal laboratories were a common fixture in medical<br />

schools until the last two decades, when their use and popularity<br />

declined significantly. Live animal laboratories were commonly<br />

used to acquaint medical students with surgical and internal procedures<br />

on living anatomy. While first-hand familiarity with anatomy is<br />

vital knowledge for a future surgeon or practitioner of professional<br />

medicine on humans, there have been longstanding concerns by<br />

many parties as to the ethical nature of using live animals.<br />

Common practice dictated that laboratory subjects, typically<br />

dogs, sheep, and pigs, be anesthetized during procedures per-<br />

formed in animal laboratories, however, they were generally euthanized<br />

at the conclusion of the lab experience. The euthanasia was<br />

considered a kindness for the laboratory animals, which would be<br />

greatly injured during these exploratory and practice procedures.<br />

The majority of live animal laborites were required curriculum for<br />

medical students and, until recent decades, could not be opted<br />

out of or replaced with alternative curriculum. Should a student<br />

have ethical compunctions with the requirements of the laboratory<br />

curriculum, they would often be dismissed from their program for<br />

failing to complete the animal laboratory prerequisite.<br />

Although firsthand experience is undoubtedly the best way<br />

for any learning to take place, the affordability and adaptability<br />

of programs used to instruct medical students were the primary<br />

concerns of many training institutions. Recent advancements in<br />

medical, materials, and computer sciences have made realistic<br />

simulation software, tools, and environments a viable and affordable<br />

alternative to instruct medical students. Instituting advanced<br />

simulation environments that can accurately model human physiology<br />

has made animal laboratories a less affordable and less accurate<br />

model for instructing internal medicine.<br />

Pairing simulation and practice environments with clinical experiences,<br />

wherein a medical student observes and assists experienced<br />

professionals, is not only better aligned to the goals of medical learning<br />

curriculum, but may cost less, financially and ethically, over time.<br />

Although the use of animal laboratories persists in medical<br />

research fields and in some advanced surgical training programs,<br />

there is some hope that the advanced technical and simulation<br />

models of the near future will outdate experimentation on live animals<br />

in these fields as well.<br />
