Data & Quality Improvement

The HRET HIIN project aims to reducing all-cause inpatient harm by 20 percent and readmissions by 12 percent in participating hospitals. A key component to making patient care safer in your hospital is to track your progress towards improvement using clinical data.

Data Tools. The HRET HIIN project provides a number of tools to support you in this effort. Specifically, the Encyclopedia of Measures (EOM) which serves as the measure reference guide for core evaluation and additional required topic measures. Tracking your data in this manner will provide you with the valuable information you need to study your data across time using run charts, and determine the effect your improvement strategies are having in your hospital at reducing patient harm.

Submitting Data.  If your hospital will be joining the HRET HIIN NHSN group to confer rights to the data from NHSN, the NHSN Group Instructions will guide you through this process.

The Comprehensive Data System is the secure, web-based data collection and reporting system that hospitals use for HIIN. For instructions on how to set up user accounts in CDS, please see the guide for hospitals that are NEW to CDS, and another guide for RETURNING hospitals. These Quick Start Guides cover logging into CDS and walk you through how to set up user accounts for your hospital.

For instructions on how to perform data entry in CDS, please see the CDS Data Entry Quick Start Guide.
