Barcode medication administration technology use in hospital practice:A mixed-methods observational study of policy deviations

INTRODUCTION: Barcode medication administration (BCMA) can, if poorly implemented, cause disrupted workflow, increased workload and cause medication errors. Further exploration is needed of the causes of BCMA policy deviations.OBJECTIVE: To gain an insight into nurses' use of barcode technology during medication dispensing and administration; to record the number and type of BCMA policy deviations, and to investigate their causes.METHODS: We conducted a prospective, mixed-methods study. Medication administration rounds on two hospital wards were observed using a digital tool and field notes. The SEIPS (Systems Engineering Initiative for Patient Safety) model was used to analyse the data.RESULTS: We observed 44 nurses administering 884 medications to 213 patients. We identified BCMA policy deviations for more than half of the observations; these related to the level of tasks, organisation, technology, environment and nurses. Task-related policy deviations occurred with 140 patients (66%) during dispensing and 152 patients (71%) during administration. Organisational deviations included failure to scan 29% of medications and 20% of patient's wristbands. Policy deviations also arose due to technological factors (eg, low laptop battery, system freezing), as well as environmental factors (eg, medication room location, patient drawer size). Most deviations were caused by policies that interfere with proper and safe BCMA use and suboptimal technology design.CONCLUSION: Our findings indicate that adaptations of the work system are needed, particularly in relation to policies and technology, to optimise the use of BCMA by nurses during medication dispensing and administration. These adaptations should lead to enhanced patient safety, as the absolute goal with BCMA implementation.
