Hypothesis
What are the total direct medical costs associated with adverse events and preventable adverse events in Dutch hospitals?
Conclusion
Preventable adverse events account for a significant portion of the national health care budget, primarily due to excess hospital stays.
Supporting Evidence
- The annual direct medical costs for all adverse events were estimated at €355 million.
- Preventable adverse events accounted for €161 million of the total costs.
- 30,000 hospital admissions involved preventable adverse events, representing 2.3% of all admissions.
Takeaway
When patients have problems in the hospital that could have been avoided, it costs a lot of money because they have to stay longer.
Methodology
The study involved a retrospective review of patient records from 21 hospitals, assessing direct medical costs related to adverse events.
Potential Biases
Potential biases may arise from retrospective analysis and the subjective nature of determining adverse events.
Limitations
The study may underestimate costs due to incomplete data and underreporting of non-invasive procedures.
