The Long-term Medical Holographic program (LMH) was a project in development by Lewis Zimmerman in which a holographic doctor would be designed to operate as a medical practitioner on a long-term basis in a location or situation where a person could not.
In 2373, Zimmerman chose Julian Bashir as the template for the LMH and came to Deep Space 9 to create the program. Zimmerman was also keen for the LMH to have an approachable manner, and so planned to incorporate detailed information about Bashir into the program. Work on the program was halted when it was revealed Bashir had been genetically enhanced as a child by a procedure illegal in the Federation. (DS9 episode: "Doctor Bashir, I Presume")
Zimmerman decided to continue with the LMH project, although it was still in the planning stages in 2375 and Zimmerman was more focused on perfecting the EMH Mark Two. (DS9 short story: "So a Horse Walks into a Bar...")
