Which type of data consists of factual details aggregated or summarized from a group of health records that provides no means to identify specific patients?

Derived
Original
Protected
Source

The correct answer is: Derived

The correct answer is derived data. This type of data is the result of processing or analyzing original health records, which are often detailed and specific to individual patients. Derived data aggregates or summarizes information, stripping away identifiable details about individual patients. This means that while it presents useful insights or statistics about a population or group of patients, it does not allow for the identification of any specific individual within that dataset. Derived data can include averages, trends, or percentages that inform healthcare providers and policymakers about general health outcomes, resource utilization, or disease prevalence without revealing sensitive personal information. This makes it highly valuable in research, quality improvement initiatives, and health system planning, as it emphasizes privacy while still facilitating decision-making based on health information. In contrast, the other types — original, protected, and source data — either refer to data that includes personal identifiers or are specifically protected under privacy regulations, which counter the requirement for anonymity in aggregated datasets.
