Why was it done?

Medication dispensing is a time-consuming, labour-intensive, error-prone process in the daily routine on the wards. The project was triggered by the tight personnel situation during the Coronavirus pandemic: In November 2020 three wards with COVID-19 patients (91 beds) were integrated into our Unit Dose blister service to assist the nursing staff. A multidisciplinary effort (management, IT-department, doctors, nursing staff, pharmacy holding a GMP-manufacturer´s certificate) and long-established electronic patient records including medication data enabled fast realisation.
After transformation back to a chirurgical, an internal and a geriatric ward the service was continued and extended to the neurological unit (49 beds) due to positive feed-back. We wanted to study the observed positive effects of Unit Dose supply in more detail.

What was done?

In our hospital medication distribution has been switched from manual dispensing by ward staff to automated Unit Dose blister packaging by the pharmacy. Our study investigates the impacts of this change on medication safety, staff satisfaction, time and drug resources.

How was it done?

The percentage of pharmacy-blistered drugs, time gain for nursing staff, employee satisfaction, medication consumption and erroneous blister fillings were investigated.

What has been achieved?

Unit Dose in hospitals is not standard for many countries and is so far unique in Austria. Therefore, we would like to share our experiences and findings with our colleagues: Solid, oral dosage forms could be supplied by 99% via Unit Dose. Time for manual drug dispensing was reduced by 75%. A survey showed high employee satisfaction with the supply process as well as the quality and correctness of the blisters. Consumption of blisterable drugs and stocks on the ward were reduced by 44% and 78%, respectively. Errors in blister fillings in our setting amount to 0,006%. When compared to literature references on error rates for manual medication dispensing (up to low double-digit rates), patients benefit from increased drug therapy safety. On the basis of these results our initiative was granted the Austrian Patient Safety Award 2021 in the field of medication safety.

What next?

We plan to extend Unit Dose to the remaining wards and to investigate patient satisfaction with the blisters, cost-efficiency and distribution of high-cost medications.
