Relevant EPCs chosen by participants

EPC	EPC description	Rationale for use
2	A shortage of time available for error detection and correction	Given the workload of the nursing staff due to the number of patients to be seen and the additional administrative tasks to be performed, there is little time to check for errors
6	A mismatch between an operator’s model of the world and that of a designer – also known as Model Mismatch	There is often poor interface design, particularly in the labelling of medicines. Designers do not consider the needs of nurses and pharmacists
17	Little or no independent checking or testing of output	Due to staff shortages and workload, it is often not possible to carry out any independent verification of results
32	Inconsistency of meaning of displays and procedures	The design of displays (labelling) often is inconsistent with the type of medicine, level of risk, or the needs of those administering the medicine. Poorly designed displays
39	Distraction/Task Interruption	Due to the presence of family members and other professionals in the area, distractions/interruptions might occur frequently
