In his old age, Bäck commented that medical teaching in Uppsala was in a sorry state during the latter part of the tenure of Olof Rudbeck the Younger and Lars Roberg.

He also opined that the presence of Nils Rosén von Rosenstein, who taught from 1731 and became professor in 1740, led to a great improvement.

[1] Under Rosén von Rosenstein, Bäck's medical studies had a contemporary content and an empirical focus.

From Bäck's point of view, such a hospital would lead to improved medical education, and remove the necessity for young Swedish physician to travel abroad to gather sufficient experience.

After some delay Serafimerlasarettet, Sweden's first modern hospital, opened in 1752, and Bäck worked as a physician there.
