Introduction: Nurses play a significant role in ensuring the safety and quality of drugs. Our aim was to assess significant factors in nurses' participation in ensuring pharmacotherapy safety by reporting adverse drug reactions (ADR) and detecting substandard drugs (SD).
Materials and methods: The study was a cross-sectional, comparative survey, using original questionnaires. Survey questions were grouped to probe the opinions, attitudes and practices of nurses reporting ADRs and SDs. Data were obtained from nurses working in teaching hospitals in Poland (group A) and, for comparison, in the USA (group B). 1200 questionnaires were distributed in Poland (return rate: 55.7%) and 200 questionnaires in the USA (return rate: 73%). Both groups were surveyed during the same period. There were no exclusion criteria. The questionnaires were self-administered. Distribution and collection were anonymous. Participation was voluntary. The Spearman correlation test was used. Both groups' responses were cross-tabulated and compared using Fisher's Exact Test for Count Data.
Results: The study group comprised 669 Polish and 146 American professionally active nurses working in general care and surgical departments. Age range: 18 to 72 years. Median job seniority: 18.3 years (group A) and 20.6 years (group B). Education levels varied. ADR reporting conditions in Poland are unfavorable: shortage of time-83.9% vs 22.6% in the US (p = 0.01); no incentive-58.2% vs 6.1% in the US (p = 0.01); and no equipment-44.7% vs 2.8% in the US (p < 0.01). Both Polish and American nurses indicate they rarely report SDs, with rates of 0.4% and 11% (p < 0.0001) respectively, during the study period.
Conclusions: Nurses in Poland are insufficiently prepared to ensure drug safety conscientiously and responsibly. Training is required for Polish nurses. Nurses' employers need to improve conditions to enable reporting of ADRs and SDs.
