What is an evidence-based staffing model, and how does it influence patient outcomes?

• A. Staffing based on evidence from data on patient acuity and workforce effectiveness; improves safety, satisfaction, and outcomes.
• B. Staffing based on personal preference.
• C. Staffing minimal to save costs.
• D. Staffing random.

Answer: (D)

Staffing decisions guided by data on patient needs and how staffing affects care outcomes. An evidence-based staffing model uses objective information such as patient acuity, complexity, census, and evidence about how different staff mixes impact safety and quality. By translating that data into staffing patterns—how many nurses, with what skill sets, are assigned to each unit and shift—leaders ensure the right resources are available to meet actual workload. This alignment leads to safer care, more timely interventions, fewer avoidable errors, and higher patient satisfaction, while also supporting staff well-being and reducing burnout. In contrast, choosing staffing based on personal preference, cost-cutting to the minimum, or random assignment ignores patient needs and tends to compromise safety and outcomes.
