Information in a data warehouse can be used to:

• A. Support hospital billing and revenue cycles
• B. Support decision support systems and executive information systems
• C. Dispel myths about the cost of care
• D. Dispel the need for decision support systems and executive information systems

Answer: (B)

Data warehouses organize integrated, historical data from multiple sources to enable analysis and informed decision-making. This foundation supports decision support systems and executive information systems by providing a single, reliable source for ad hoc queries, trend analysis, and strategic reporting. In healthcare, this means leaders can monitor patient outcomes, utilization, and costs over time, create dashboards, and perform analyses that inform budgeting and policy decisions. While a data warehouse can aid financial insights, its primary strength is enabling broad decision support across the organization, not just billing. It does not dispel myths about costs, and it certainly doesn’t negate the need for decision support systems and executive information systems; instead, it provides the data those systems rely on.
