Developing and user testing new pharmacy label formats-A study to inform labelling standards.

BACKGROUND: Dispensed prescription medicine labels (prescription labels) are important information sources supporting safe and appropriate medicines use. OBJECTIVE: To develop and user test patient-centred prescription label formats. METHODS: Five stages: developing 12 labels for four fictitious medicines of varying dosage forms; diagnostic user testing of labels (Round 1) with 40 consumers (each testing three labels); iterative label revision, and development of Round 2 labels (n = 7); user testing of labels (Round 2) with 20 consumers (each testing four labels); labelling recommendations. Evaluated labels stated the active ingredient and brand name, using various design features (eg upper case and bold). Dosing was expressed differently across labels: frequency of doses/day, approximate times of day (eg morning), explicit times (eg 7 to 9 AM), and/or explicit dosing interval. Participants' ability to find and understand medicines information and plan a dosing schedule were assessed. RESULTS: Participants demonstrated satisfactory ability to find and understand the dosage for all label formats. Excluding active ingredient and dosing schedule, 14/19 labels (8/12 in Round 1; 6/7 in Round 2) met industry standard on performance. Participants' ability to correctly identify the active ingredient varied, with clear medicine name sign-posting enabling all participants evaluating these labels to find and understand the active ingredient. When planning a dosing schedule, doses were correctly spaced if the label stated a dosing interval, or frequency of doses/day. Two-thirds planned appropriate dosing schedules using a dosing table. CONCLUSIONS: Effective prescription label formatting and sign-posting of active ingredient improved communication of information on labels, potentially supporting safe medicines use. PATIENT AND PUBLIC INVOLVEMENT: Consumers actively contributed to the development of dispensed prescription medicine labels. Feedback from consumers following the first round was incorporated in revisions of the labels for the next round. Patient and public involvement in this study was critical to the development of readable and understandable dispensed prescription medicine labels.

The contribution of labelling to safe medication administration in anaesthetic practice.

The administration of medications is central to anaesthetists' care of patients. Errors are inevitable in any human endeavour, but should be distinguished from violations. The incidence of medication errors in anaesthesia has been estimated as 1 per 13,000 administrations, excluding errors in recording. Adverse medication events follow a proportion of these errors. Labelling is a key element of medication safety. There is a long-standing need for improvements in the labelling of ampoules and vials. An international standard exists for labelling syringes used during anaesthesia (ISO 26825). Australia has recently released national recommendations for labelling lines and injectable medications that complement this and other relevant standards. The provision of at least some medications in pre-filled syringes would reduce the number of steps involved in medication administration, increase the certainty that syringe labels are correct and probably reduce medication errors. Pre-printed, peel-off flag labels on ampoules and vials are a less expensive alternative to pre-filled syringes to facilitate correct labelling. The medication name on user-applied labels should be matched to that on the relevant ampoule or vial at the time of drawing up any medication. All lines and catheters should be labelled. Any medicine or fluid that cannot be identified (e.g., in an unlabelled syringe or other container) should be considered unsafe and discarded. Reducing adverse medication events will require the engagement of individual anaesthetists.
