The only thing that I know that would be close to age relating to decreased
performance is the Annals of Internal Medicine article in 2005.
It doesn't look at stethescope use specifically.

https://annals.org/aim/fullarticle/718215/systematic-review-relationship-between-clinical-experience-quality-health-care

 (Choudhry, Niteesh K., Robert H. Fletcher, and Stephen B. Soumerai.
"Systematic review: the relationship between clinical experience and
quality of health care." *Annals of Internal medicine*142.4 (2005):
260-273.)
