CHTM case studies
CHTM · Put your knowledge to work in context.
The Certified Healthcare Technology Manager (CHTM) is a professional credential for people who lead healthcare technology management (HTM) work rather than only servicing devices. In AAMI's own materials it appears as one of four AAMI certifications - alongside CBET, CRES, and CABT - and AAMI frames certification generally as a way to build career credibility in health technology. The CHTM case studies are 5 cases and about 4,146 words.
