Medication Safety Gaps in English Pediatric Inpatient Units: An Exploration Using Work Domain Analysis

ObjectivesMedication is a common cause of preventable medical harm in pediatric inpatients. This study aimed to examine the sociotechnical system surrounding pediatric medicines management, to identify potential gaps in this system and how these might contribute to adverse drug events (ADEs).MethodsAn exploratory prospective qualitative study in pediatric wards in three hospitals in the north of England was conducted between October 2020 and May 2022. Analysis included a documentary analysis of 72 policies and procedures and analysis of field notes from 60 hours of participant observation. The cognitive work analysis prompt framework was used to generate a work domain analysis (WDA) and identify potential contributory factors to ADEs.ResultsThe WDA identified 2 functional purposes, 7 value/priority measures, 6 purpose-related functions, 11 object-related processes and 14 objects. Structured means-ends connections supported identification of 3 potential contributory factors-resource limitations, cognitive demands, and adaptation of processes. The lack of resources (equipment, materials, knowledge, and experience) created an environment where distractions and interruptions were unavoidable. Families helped provide practical support in medicines administration but were largely unacknowledged at an organizational level. There was a lack of teamwork with regards to medication with different professionals responsible for different parts of the system. Mandated safety checks on medicines were frequently omitted because of limited resources and perceived redundancy. Interventions to support adherence to safety policies were also often bypassed because they created more work.ConclusionsThe WDA has provided insights into the complex system of medication safety for children in hospital and has facilitated the identification of potential contributory factors to ADEs. We therefore advocate (in priority order) for processes to involve parents in the care of their children in hospital, development of skill-mix interventions to ensure appropriate expertise is available where it is needed, and modified checking procedures to permit staff to use their skills and judgment effectively and efficiently.
