Nature of adverse events with opioids in hospitalised patients: a post-hoc analysis of three patient record review studies.

Objective: Opioids are increasingly prescribed and frequently involved in adverse drug events (ADEs). The underlying nature of opioid-related ADEs (ORADEs) is however understudied. This hampers our understanding of risks related to opioid use during hospitalisation and when designing interventions.

Nurse compliance with a protocol for safe injectable medication administration: comparison of two multicentre observational studies.

Objectives: Medication administration errors with injectable medication have a high risk of causing patient harm. To reduce this risk, all Dutch hospitals implemented a protocol for safe injectable medication administration. Nurse compliance with this protocol was evaluated as low as 19% in 2012.
