Article Synopsis
- * The algorithm was developed in collaboration with experts and validated using data from seven hospitals; it categorized about 7.8% of readmissions as planned, with varying sensitivity and specificity rates based on hospital type.
- * Adjustments were made to improve the algorithm's performance, achieving better overall predictive values, although it struggled with accurately identifying planned readmissions for specific common procedures.
The integration of similar clinical research data collection instruments.
AMIA Annu Symp Proc
December 2004
We devised an algorithm for integrating similar clinical research data collection instruments to create a common measurement instrument. We tested this algorithm using questions from several similar surveys. We encountered differing levels of granularity among questions and responses across surveys resulting in either the loss of granularity or data.

They achieve this by using an Entity-Attribute-Value (EAV) model for clinical data. While very flexible for creating transaction-oriented systems for data entry and browsing of individual forms, EAV-modeled data is unsuitable for direct analytical processing, which is the focus of data marts.
