Background:
Health care workers' compliance with isolation precautions for patients colonized or infected with multidrug-resistant bacteria (MRB) is low.
Methods:
In a 750-bed, acute care university hospital with a patient information system covering the entire hospital, a database that included all patients with MRB was created and was merged daily with the admission-discharge-transfer application. An electronic alert was generated for all new cases of MRB and for all transfers between wards and all readmissions of patients with MRB. Two successive interventions were implemented based on this alert system. First, alerts were dispatched to medical and staff members in charge of infection control in each ward with requests to order isolation precautions for the patients. Second, alerts were dispatched to the infection control team, who directly ordered implementation of isolation precautions in electronic nursing records. Five audits during a 3-year period were performed to evaluate their effect on health care workers' compliance with isolation precautions.
Results:
Awareness of the MRB status for the nurses in charge of the patients statistically significantly increased from 24.0% at baseline to 59.4% at 1 year after the first intervention. This proportion improved to 93.1% at 1 year after the second intervention. Similarly, the implementation of isolation precautions statistically significantly increased from 15.0% at baseline to 50.5% at 1 year after the first intervention and then to 90.2% at 1 year after the second intervention.
Conclusion:
A computer alert system can lead to effective and lasting improvement in the implementation of isolation precautions for patients with MRB in health care institutions.
Insights
Implementing a computer alert system significantly improved healthcare workers' adherence to isolation precautions for patients with multidrug-resistant bacteria (MRB). This system enhanced awareness and compliance, crucial for infection control in hospitals.
Area of Science:
- Infectious Diseases
- Hospital Epidemiology
- Health Informatics
Background:
- Low compliance with isolation precautions for multidrug-resistant bacteria (MRB) poses a significant infection control challenge in healthcare settings.
- Multidrug-resistant bacteria (MRB) infections require strict adherence to isolation protocols to prevent transmission.
Purpose of the Study:
- To evaluate the effectiveness of a computer-based alert system in improving healthcare workers' compliance with isolation precautions for patients with MRB.
- To assess the impact of two successive interventions utilizing an electronic alert system on isolation precaution implementation.
Main Methods:
- A database of patients with MRB was integrated with the hospital's patient information system to generate daily electronic alerts.
- Two interventions were implemented: alerts to ward staff and direct orders to the infection control team via electronic nursing records.
- Five audits over three years assessed the impact of the alert system on compliance with isolation precautions.
Main Results:
- Awareness of patient MRB status among nurses increased from 24.0% at baseline to 93.1% after the second intervention.
- Implementation of isolation precautions rose significantly from 15.0% at baseline to 90.2% after the second intervention.
- The computer alert system demonstrated a statistically significant and sustained improvement in adherence to isolation protocols.
Conclusions:
- A computer alert system is an effective tool for enhancing the implementation of isolation precautions for patients with MRB.
- Electronic alert systems can lead to lasting improvements in infection control practices within healthcare institutions.
- This technology-driven approach offers a scalable solution for improving compliance with critical patient safety protocols.
