Exploring the Correlation Between Patient Safety Culture and Adverse Medical Events Using Failure Mode and Effect
1Department Medical Affairs, Fourth Affiliated Hospital of Harbin Medical University, Harbin, Heilongjiang, People's Republic of China.
Objective:
This study aimed to explore the correlation between medical safety adverse events and patient safety culture through the lens of Failure Mode and Effect Analysis (FMEA).
Methods:
Sixty patients from a hospital were selected as the research subjects, alongside 440 medical staff members (including clinical, medical technology, and management personnel) who participated in the study. The general demographic characteristics of medical staff, patient safety culture, and adverse medical safety events were investigated. FMEA was employed to analyze the relationship between medical safety adverse events and patient safety culture, using the risk priority number (RPN) as a key metric.
Results:
A comparison of RPN values before and after FMEA intervention revealed that the RPN values of each failure mode significantly decreased post-intervention. Correlation analysis showed significant relationships between medication errors and several factors: "incident reporting frequency" (OR=0.706), "manager expectations and actions to promote patient safety" (OR=0.733), and "management support for patient safety" (OR=0.755). Pressure ulcers were significantly correlated with "manager expectations and actions to promote patient safety" (OR=0.729) and "shift and transfer" (OR=0.707). Falls were notably associated with "interdepartmental cooperation" (OR=0.735), "feedback and communication about errors" (OR=0.756), and "shift and transfer" (OR=0.660). Additionally, a strong correlation was identified between adverse events and "management support for patient safety" (OR=0.701).
Conclusion:
Utilizing FMEA to analyze the correlation between medical safety adverse events and patient safety culture is effective in identifying specific dimensions of these events related to safety culture. This enables the development of targeted interventions to mitigate adverse events and enhance patient safety.
Insights
Failure Mode and Effect Analysis (FMEA) effectively linked patient safety culture to adverse medical events. Interventions targeting incident reporting, management actions, and communication significantly reduced risks, enhancing overall patient safety.
Area of Science:
- Healthcare Management
- Patient Safety Research
- Risk Analysis
Background:
- Patient safety culture is crucial for preventing adverse medical events.
- Understanding the correlation between safety culture and specific adverse events is essential for targeted interventions.
- Failure Mode and Effect Analysis (FMEA) offers a systematic approach to analyze these relationships.
Purpose of the Study:
- To explore the correlation between medical safety adverse events and patient safety culture using FMEA.
- To identify specific patient safety culture dimensions associated with medication errors, pressure ulcers, and falls.
- To evaluate the effectiveness of FMEA in analyzing these correlations.
Main Methods:
- A study involving 60 patients and 440 medical staff from a hospital.
- Investigation of demographic characteristics, patient safety culture, and adverse medical safety events.
- Application of FMEA with Risk Priority Number (RPN) to analyze the relationship between adverse events and safety culture.
Main Results:
- FMEA intervention significantly reduced RPN values, indicating decreased risk.
- Medication errors correlated with incident reporting, manager expectations, and management support.
- Pressure ulcers linked to manager expectations and shift/transfer processes.
- Falls associated with interdepartmental cooperation, error communication, and shift/transfer.
- Adverse events showed a strong correlation with management support for patient safety.
Conclusions:
- FMEA is an effective tool for analyzing the link between adverse events and patient safety culture.
- The study identified specific safety culture dimensions that influence different types of adverse events.
- Findings support the development of targeted interventions to mitigate risks and improve patient safety outcomes.
