Insights
Implementing a voice recognition system (VRS) significantly reduced medication errors in a Kenyan pediatric emergency department, particularly incorrect dosages. The technology was also found to be acceptable to healthcare providers.
Area of Science:
- Health Informatics
- Patient Safety
- Clinical Pharmacy
Background:
- Medication errors contribute significantly to mortality, with higher risks in pediatric populations.
- Research on medication errors in sub-Saharan Africa is limited due to competing health priorities.
- Voice recognition systems (VRS) offer a potential technological solution to improve prescription accuracy.
Purpose of the Study:
- To evaluate the impact of introducing a voice recognition system (VRS) on medication error prevalence.
- To characterize medication errors and assess the acceptability of VRS among healthcare providers.
Main Methods:
- A before-and-after intervention study design was employed.
- The study was conducted in a Pediatric Accident and Emergency Department in Kenya.
- Prescription records were analyzed pre- and post-VRS implementation.
Main Results:
- A reduction in medication prescription errors was observed after VRS implementation (74.3% pre-VRS vs. 65.7% post-VRS).
- The greatest reduction was noted in incorrect medication dosages.
- Over half (58%) of providers preferred VRS over handwritten prescriptions.
Conclusions:
- Voice recognition systems effectively reduce medication prescription errors, especially dosage errors.
- VRS technology is acceptable to physicians and pharmacists in a Kenyan tertiary care setting.
- Further research on training, user experience, and software enhancement is recommended to further minimize errors.
Background:
Medication-related errors account for one out of every 131 outpatient deaths, and one out of 854 inpatient deaths. The risk is threefold greater in the pediatric population. In sub-Saharan Africa, research on medication-related errors has been obscured by other health priorities and poor recognition of harm attributable to such errors.Our primary objective was to assess the effect of introduction of a voice recognition system (VRS) on the prevalence of medication errors. The secondary objective was to describe characteristics of observed medication errors and determine acceptability of VRS by clinical service providers.
Methods:
This was a before-after intervention study carried out in a Pediatric Accident and Emergency Department of a private not-for-profit tertiary referral hospital in Kenya.
Results:
A total of 1196 handwritten prescription records were examined in the pre-VRS phase and 501 in the VRS phase. In the pre-VRS phase, 74.3% of the prescriptions (889 of 1196) had identifiable errors compared with 65.7% in the VRS phase (329 of 501).More than half (58%) of participating clinical service providers expressed preference for VRS prescriptions compared with handwritten prescriptions.
Conclusions:
VRS reduces medication prescription errors with the greatest effect noted in reduction of incorrect medication dosages. More studies are needed to explore whether more training, user experience and software enhancement would minimize medication errors further. VRS technology is acceptable to physicians and pharmacists at a tertiary care hospital in Kenya.
