Educational interventions to reduce nurse medication interruptions: A scoping review

Preventable harm from medicines is a global problem creating huge economic and social burden. Interruptions occur frequently in clinical environments causing medication episodes to take longer and having a cognitive cost on the nurse.

The aim of this scoping review is to identify and evaluate educational interventions that have been employed to reduce medication interruptions and improve medication safety.

Six databases were searched for the scoping review (PubMed, Embase, Cochrane Library, CINAHL, Pishin and Medline) along with reference lists and grey literature searches. Articles were included if they were written in English, published between 2010 and 2020 and employed an education intervention (including bundled interventions). Databases were searched using keywords and Boolean operators.

Eight studies met the inclusion criteria. Seven of these studies were conducted in hospital (adults n = 6, paediatric n = 1) and one study in a university with undergraduate nurses. Four studies used a combined intervention and four exclusively employed an education intervention. Five studies found a significant decrease in the number of interruptions post intervention, but one of the studies that exclusively employed an education intervention found no significant difference. Changes in the nurses' behaviour post intervention were also cited in two studies.

There was a lack of exclusive education interventions, making it difficult to determine the effectiveness of education at reducing medication interruptions. This review highlights the necessity of some interruptions when performing tasks, for example, to make a nurse aware of a deteriorating patient. However, as the majority of studies used the number of interruptions to determine the effectiveness of the intervention, there is uncertainty as to whether this is the right outcome measure to use. In the future, a focus on outcome measures reflecting change in nurse behaviour may be more effective in determining the strength of an educational intervention.
