The German population is aging, as is the situation in many nations, including the United States. Patients who didn’t learn a second language growing up need nursing staff who can accommodate them. And in other instances, this necessitates hiring nurse staff from outside to cover the gap. German-speaking nurses are clearly in demand, both domestically and abroad. The capacity to communicate directly with elderly populations could be invaluable as they may speak German more fluently than younger generations.
Eliminating a communication gap between oneself and a patient saves the time spent attempting to interpret their symptoms. Speaking to a patient in their own language allows one to be far more exact, which is crucial because minor details can mean the difference between two diagnoses. Being able to speak another language well distinguishes oneself from the competition. Fluency in the local language is a need if you want to practice medicine in a German-speaking nation.
