Data Updates

MaineTracking Network is ever-evolving. This page highlights the data portal topics we updated from 2022 to present.

  • Annual update refers to a scheduled update that may include new years of data, new measures (e.g., hospitalizations, emergency department visits), new display types (e.g., near real-time, trend-charts), or even new data portal topics.

  • Erratum refers to an identified data discrepancy. For an explanation of what took place and if changes in procedures were needed and added, please refer to the Details column.
