My company has a medical data dictionary from a client that needs to be mapped to the HL7 standard. This new document will become the technical spec for developers to eventually write code from. I can provide the data dictionary and a sample mapping from work that has been completed. There may be items in the data dictionary that do not easily map to the HL7 standard as the normal patient demographics and medical history do due to the unique requirements from my client. The data dictionary consists of Basic Screening, Physican Information, General History and ( Medical History may be added) Currently there are 33 high level items that need to be mapped each item containing lower level items to be mapped. Understanding of the HL7 standard is necessary.
