[Patient safety: current problems and challenges].

Area of Science:

• Health Services Research
• Patient Safety Studies

Background:

• The seminal "To Err Is Human" report highlighted patient safety issues in the US.
• The German Patient Safety Alliance (APS) has released a "White Paper on Patient Safety".
• Existing patient safety metrics often focus solely on adverse events (AE).

Purpose of the Study:

• To propose a revised definition and concept of patient safety.
• To develop a new measurement framework for patient safety.
• To analyze obstacles and recommend interventions for improving patient safety in Germany.

Main Methods:

• Utilizing a throughput model from health services research.
• Developing patient safety indicators beyond AE rates, including innovation competence.
• Analyzing epidemiological data and obstacles to patient safety improvement.

Main Results:

• Avoidable adverse events (AE) are estimated at 2-4% and avoidable deaths at 0.1% in hospitals, considered conservative.
• Data from legal proceedings "litigation gap" underestimate AE frequencies by a factor of 30.
• Complex, multicomponent interventions are recommended over single-point or technical solutions.

Conclusions:

• Patient safety requires a systemic approach, prioritizing sustainable improvement processes.
• Measuring patient safety should encompass innovation competence alongside AE reduction.
• Multicomponent interventions targeting team and management levels are crucial for enhancing patient safety in Germany.
