Abstract

Amaç: Bu çalışmanın amacı, kalp cerrahisi hemşirelerine warfarin kullanımına ilişkin verilen eğitimin etkinliğinin değerlendirilmesidir.
Yöntemler: Ön test-son test yarı deneysel tipte olan bu çalışma, Haziran ve Temmuz 2025 tarihleri arasında bir üniversite hastanesinin Kalp ve Damar Cerrahisi Anabilim Dalı’nda yürütülmüştür. Çalışmanın örneklemini klinik ve yoğun bakım ünitesinde çalışan, çalışmaya katılmaya gönüllü olan 30 hemşire oluşturmuştur. Araştırma kapsamında hemşirelere warfarin kullanımı konusunda eğitim verilmiş olup hemşirelerin bilgileri eğitim öncesi ve sonrası ölçülerek eğitimin etkinliği değerlendirilmiştir.
Bulgular: Araştırmaya katılan hemşirelerin yaş ortalaması 33.30±6.62 yıldır. Hemşirelerin eğitim öncesi warfarin kullanımına ilişkin bilgi puanı ortalaması 15.00±2.74 iken eğitim sonrası 18.03±1.29’a yükselmiştir. Hemşirelerin eğitim öncesi warfarin-ilaç etkileşimleri ile ilgili bilgi puan ortalaması 13.40±14.40’tan 41.80±10.43’e ve warfarin-besin-bitki etkileşimleri ile ilgili bilgi puan ortalaması da 9.73±5.51’den 24.60±11.05’e yükselmiştir.
Sonuç: Bu çalışmada, kalp cerrahisi hemşirelerinin warfarin kullanımına ilişkin bilgilerinin orta düzeyin üzerinde, ilaç, besin-bitki etkileşimlerine yönelik bilgilerinin yetersiz düzeyde olduğu; eğitim sonrası ise bilgi düzeylerinde belirgin artış sağlandığı saptanmıştır.

Cardiac surgery nurses' knowledge of warfarin: evaluation of a training activity

https://izlik.org/JA67MW98KG

Abstract

Aims: The aim of this study is to evaluate the effectiveness of the training provided to cardiac surgery nurses regarding warfarin use.
Methods: This pre-test-post-test quasi-experimental study was conducted between June and July 2025 at the department of cardiovascular surgery of a university hospital. The sample consisted of 30 nurses working in the clinic and intensive care unit who volunteered to participate in the study. As part of the research, nurses were educated on warfarin use, and their knowledge was measured before and after the training to evaluate the effectiveness of the training. Data were analysed using SPSS 25.0. Descriptive statistics were calculated, and pre- and post-test scores were compared using the Wilcoxon signed-rank test.
Results: The average age of the nurses participating in the study was 33.30±6.62 years. The average pre-training knowledge score of nurses regarding warfarin use was 15.00±2.74, while the post-training score increased to 18.03±1.29. The average knowledge score of nurses regarding warfarin-drug interactions before training was 13.40±14.40, while after training it was 41.80±10.43, and the average knowledge score regarding warfarin-food-herb interactions increased from 9.73±5.51 to 24.60±11.05. According to the Wilcoxon signed-rank test results, statistically significant increases were observed in nurses’ knowledge scores regarding warfarin use and, warfarin–drug interactions, and warfarin–food–herb interactions after the training (p<0.001). The large effect sizes indicate that the training had a strong impact across all knowledge domains.
Conclusion: This study found that cardiac surgery nurses had a sufficient level of knowledge regarding warfarin use but insufficient knowledge about drug, food and herb interactions; however, the educational intervention led to statistically significant improvements with large effect sizes across all knowledge domains.
