一覽

Master Patient Index (MPI) is a database matching patients across hospital systems and providers. A patient visits Hospital A (gets ID 12345), then Hospital B (unaware of A). Without MPI, Hospital B creates new ID (98765). Now there are two records for one patient, fragmented medical history, duplicate tests, wrong medications. MPI uses name, DOB, SSN, phone to identify and merge. Mastery takes 8-10 weeks. Specialists earn 20-25% premium because accurate patient identity is literally life-or-death (wrong med kills patient). The skill sits at the intersection of healthcare IT, data quality, and identity matching.

什麼是 Master Patient Index MPI

Master Patient Index (MPI) is a healthcare IT system that maintains a single, authoritative patient identity record across a healthcare organization or network. When a patient visits multiple hospitals, clinics, or providers, MPI ensures they have one unified identity. This enables complete medical history, coordinated care, and prevents duplicate tests, medication conflicts, and medical errors. An MPI system: collects patient demographics (name, DOB, SSN, contact info), deduplicates records (matches similar records across systems), merges fragmented histories, and provides a single patient ID for providers to use. Behind the scenes: probabilistic matching algorithms, data quality tools, human review workflows.

❓ 常見問題

Why is MPI so important in healthcare?
Fragmented patient records = bad medicine. Doctor doesn't know patient is allergic to Penicillin (allergy in Hospital A's system, new doc at Hospital B unaware). Prescribes Penicillin. Patient has severe reaction or dies. MPI ensures every doctor has complete medical history.
What's record linkage, and how does it work?
Matching records that belong to the same person despite name variations, typos, or missing data. Example: 'John Smith, DOB 1/1/1980' (Hospital A) vs. 'Jon Smyth, DOB 1/1/1980' (Hospital B). Probabilistic algorithms score similarity (name match, DOB match) and merge if score > threshold.
How do I handle false matches?
Two unrelated people with similar names/DOBs (John Smith born 1980). Probabilistic algorithm may match them. Human reviewers (MPI staff) validate matches before merging. Balance: high sensitivity (find all matches) vs. high specificity (avoid false matches).
What about privacy when linking patient records?
HIPAA requires patient consent for data sharing between providers (with exceptions). MPI links records within healthcare system (one hospital network). Inter-system linking requires consent or legal authority. Privacy impact assessments required.
Can blockchain or distributed ledgers replace MPI?
Patient-controlled identity on blockchain is emerging. Patient holds their own ID, grants access to providers. But traditional MPI still needed for legacy systems. Transition will take decades. For now, centralized MPI is standard.
