What type of data is used to compare process performance before and after a change?

The correct answer is based on the concept of baseline data, which is essential for evaluating changes in process performance. Baseline data refers to the initial set of data collected before a change is implemented. This data provides a reference point to measure and compare the outcomes after modifications or interventions have been made. By establishing a baseline, organizations can effectively assess the impact of changes on various performance metrics, thereby identifying whether those changes lead to improvements, regressions, or no significant variations.

In the context of process performance, having a clear baseline allows health information management professionals to make data-driven decisions, guide quality improvement initiatives, and ensure that any observed changes are indeed attributable to the actions taken rather than external factors. This systematic approach is vital in areas such as quality control, patient safety, and overall operational efficiency.
