The nature, severity and causes of medication incidents from an Australian community pharmacy incident reporting system: The QUMwatch study.

Aims: Most research into medication safety has been conducted in hospital settings with less known about primary care. The aim of this study was to characterise the nature and causes of medication incidents (MIs) in the community using a pharmacy incident reporting programme.

Methods: Thirty community pharmacies participated in an anonymous or confidential MI spontaneous reporting programme in Sydney, Australia. The Advanced Incident Management System was used to record and classify incident characteristics, contributing factors, severity and frequency ratings.

Results: In total, 1013 incidents were reported over 30 months, 831 of which were near misses while 165 reports involved patient harm. The largest proportion of cases pertained to patients aged >65 years (35.7%). Most incidents involved errors during the prescribing stage (61.1%), followed by dispensing (25.7%) and administration (23.5%), while some errors occurred at multiple stages (17.9%). Systemic antibacterials (12.2%), analgesics (11.8%) and renin-angiotensin medicines (11.7%) formed the majority of implicated classes. Participants identified diverse and interrelating contributing factors: those concerning healthcare providers included violations to procedures/guidelines (75.6%), rule-based mistakes (55.6%) and communication (50.6%); those concerning patients included cognitive factors (31.9%), communication (25.5%) and behaviour (6.1%). Organisational safety culture and inadequate risk management processes were rated as suboptimal.

Conclusion: An MI reporting programme can capture and characterise medication safety problems in the community and identify the human and system factors that contribute to errors. Since medicine use is ubiquitous in the community, morbidity and mortality from MIs may be reduced by addressing the prioritised risks and contributing factors identified in this study.
