Comparing nursing medication rounds before and after implementation of automated dispensing cabinets: A time and motion study

Abstract

Nursing medication administration is an integral, albeit time consuming component of a nursing shift. Automated dispensing cabinets (ADCs) are a medicines management solution designed to improve both efficiency and patient safety. This study aimed to evaluate the time taken to undertake a medication round including the number of locations visited to retrieve medicines, across four different clinical specialties within one hospital. Studies to date have investigated the effect of ADCs on nursing medication rounds centred around one clinical specialty, in hospitals with varying levels of digital maturity. This study adds to the existing body of evidence by investigating multiple clinical specialties where EPMA in use throughout the study period. In this study, prior to ADC implementation nurses retrieved required medicines from shelves in the medication room, mobile medication carts, and patients' own drug (POD) lockers. Post-ADC implementation, medicines were retrieved exclusively from the ADC and POD lockers only. Nurses were observed on each ward completing medication rounds, using the data collection tool designed for this study. Pre-implementation data was collected between February and June 2023, and post-implementation data collected between July and September 2023. There was a statistically significant reduction in the time required for medicines retrieval on the surgical ward only, post- ADC implementation. The time taken to retrieve each medication went from a mean of 98.1 s to 47.2 s (p = 0.0255). When comparing all four specialties as a whole, there was a reduction in the mean time required to issue each medicine preversus post-ADC implementation, from 83.3 s to 62.6 s respectively, however this difference was not shown to be statistically significant. The mean number of locations visited to obtain all required medicines for each patient reduced significantly from 1.73 to 1.04 (p < 0.01). There is potential for improved efficiency as nurses become more familiar with new workflows. It may be of benefit to repeat this study to ascertain whether time savings have been further improved.
