Background:
Interruptions and errors during the medication process are common, but published literature shows no evidence supporting whether separate medication rooms are an effective single intervention in reducing interruptions and errors during medication preparation in hospitals. We tested the hypothesis that the rate of interruptions and reported medication errors would decrease as a result of the introduction of separate medication rooms.
Aim:
Our aim was to evaluate the effect of separate medication rooms on interruptions during medication preparation and on self-reported medication error rates.
Methods:
We performed a preintervention and postintervention study using direct structured observation of nurses during medication preparation and daily structured medication error self-reporting of nurses by questionnaires in 2 wards at a major teaching hospital in Switzerland.
Results:
A volunteer sample of 42 nurses was observed preparing 1498 medications for 366 patients over 17 hours preintervention and postintervention on both wards. During 122 days, nurses completed 694 reporting sheets containing 208 medication errors. After the introduction of the separate medication room, the mean interruption rate decreased significantly from 51.8 to 30 interruptions per hour (P < 0.01), and the interruption-free preparation time increased significantly from 1.4 to 2.5 minutes (P < 0.05). Overall, the mean medication error rate per day was also significantly reduced after implementation of the separate medication room from 1.3 to 0.9 errors per day (P < 0.05).
Conclusions:
The present study showed the positive effect of a hospital-based intervention; after the introduction of the separate medication room, the interruption and medication error rates decreased significantly.
Insights
Separate medication rooms significantly reduced interruptions and medication errors in hospital settings. This intervention improved medication safety by decreasing both interruption rates and reported errors during preparation.
Area of Science:
- Healthcare quality improvement
- Patient safety research
- Hospital administration
Background:
- Interruptions and medication errors are frequent challenges in healthcare.
- Evidence for the effectiveness of separate medication rooms as a single intervention is lacking.
- This study investigated the impact of dedicated medication rooms on hospital medication safety.
Purpose of the Study:
- To assess the effect of separate medication rooms on nurse interruptions during medication preparation.
- To evaluate the impact of separate medication rooms on self-reported medication error rates.
- To determine if dedicated medication rooms improve medication safety in hospitals.
Main Methods:
- A preintervention and postintervention study design was employed.
- Direct structured observation of nurses preparing medications was conducted.
- Nurses completed daily self-report questionnaires on medication errors over 122 days.
- The study took place in two wards of a Swiss teaching hospital.
Main Results:
- The mean interruption rate decreased significantly from 51.8 to 30 interruptions per hour (P < 0.01).
- Interruption-free medication preparation time significantly increased from 1.4 to 2.5 minutes (P < 0.05).
- The mean daily medication error rate significantly decreased from 1.3 to 0.9 errors per day (P < 0.05).
Conclusions:
- The introduction of separate medication rooms led to a significant reduction in interruptions.
- Dedicated medication rooms were associated with a significant decrease in medication errors.
- This hospital-based intervention demonstrates the effectiveness of separate medication rooms in enhancing medication safety.
