A healthcare organization is preparing training data for an AI model that predicts patient readmissions.

PMI-CPMAI aligns data preparation with executing data cleansing and enhancement activities so that datasets meet model and operational requirements. Inconsistent clinical coding is a data quality issue that threatens accuracy, fairness, and interpretability, because identical conditions may be represented differently across sources. The PMI-aligned response is to determine and apply the necessary transformation steps—standardizing codes to a controlled vocabulary, mapping local codes to a canonical schema, normalizing formats, and documenting rules and lineage so the process is auditable. Ignoring inconsistencies (B) increases noise and can embed systematic bias (e.g., certain clinics appearing “higher risk” due to coding artifacts). Relying only on synthetic data (C) can reduce fidelity if the synthetic process fails to reflect true clinical distributions. Skipping validation (D) violates responsible delivery expectations because it undermines patient safety and data integrity. PMI’s responsible and trustworthy framing supports disciplined data readiness work before model development proceeds.
