Master Patient Index and Primary Keys


The purpose of this paper is to discuss Master Patient Index and the Primary Key(s). MPI   also   provides   quick   access   by   physician   to   patient   records   over   distributed network   and   facilitates   the   presentation   of   patient   health   information   in   a   clear manner. Primary Keys are the unique identification number associated with the patient. These two are used together to improve patient care by enabling an exchange of clinical information between healthcare organization, through data sharing, using unique identifiers.

A Master Patient Index (MPI) makes use of sophisticated identifiers to allow for patient identification and linking to a patient’s electronic medical record (EMR). It basically provides a link to the correct patient record in those organizations that utilize EMRs. An MPI’s accuracy can be attributed to its matching techniques that use any available fields for matching, despite discrepancies in how various healthcare facilities track information. The Master Patient Index is an electronic medical record system for every patient registered in a health care organization. The MPI is stored in a database and contains a unique identifier, called the primary key. The primary key is unique and identifies each record in the database. The MPI is considered the most important resource in a healthcare facility. An MPI is the cornerstone of any data-sharing initiative. Without a list, to say that a specific record is in the database, there is no way to know what patients are included. An EMR provides the clinical information about a patient, while the MPI is the index for that data. The MPI will contain the nucleus about a patient such as name, address, phone number, date of birth, gender, race, social security number, and the unique patient identification number. The MPI identifies all patients that have been treated in a facility or healthcare organization....
