HL7
HL7 (Health Level Seven) is a standard way for healthcare systems to share patient information between different computers and software. Think of it like a universal language that helps hospitals, clinics, and medical software communicate with each other. Without HL7, each healthcare system might speak its own language, making it difficult to share important patient data. It's similar to how all airports use English as a standard language for air traffic control - HL7 is the "common language" for healthcare data. When you see HL7 mentioned in a resume, it means the person has experience with making different healthcare systems work together.
