California Improves Usefulness of Health Data

From 1992 to 1997, the California Health Information for Policy Project (CHIPP) sought to enrich the state's health information, particularly in the area of primary care.

Project staff attempted to improve the usefulness of statewide health data primarily by linking data from different sources and creating new methods of displaying and analyzing existing data sets.

The project was part of the Robert Wood Johnson Foundation (RWJF) Information for State Health Policy national program.

Key Results

Key accomplishments included:

  • Specific data-oriented projects (i.e., data inventory, linked files and a core data set) and efforts to disseminate information through a website.
  • The development of individual sets of linked databases (e.g., hospital discharge and birth files, hospital discharge and death files) and the creation of a core data set to facilitate linkages between diverse public health and Medicaid program data sets.
  • The project increased people's awareness of what data are available, promoted cross-agency collaboration, and brought key players together.
