Which acronym refers to a primary medical doctor?

The acronym PMD stands for Primary Medical Doctor, which is a term used to refer to a healthcare professional who serves as the main point of contact for patients within the healthcare system. The primary medical doctor is responsible for managing a patient's overall health, coordinating care with specialists, and addressing a wide range of health issues.

This distinguishes PMD from other acronyms provided. PRN stands for "pro re nata," a Latin term meaning "as needed," usually referring to medications or treatments taken when necessary rather than on a scheduled basis. PED is commonly used to denote Pediatric Emergency Department or pediatrician, which is focused on treating children rather than being a general primary care provider. POD is an abbreviation that can have various meanings based on context, such as "Post-Operative Day," but it does not refer to a primary medical doctor. Therefore, PMD is the appropriate choice for denoting a primary medical doctor.
