Abstract

Health Literacy and Knowledge Level About Warfarin Therapy Among Patients Undergoing Mechanical Valve Replacement: A Cross-Sectional Study Abstract Objective: The aim of this study was to evaluate the health literacy and knowledge levels regarding warfarin therapy among patients who underwent mechanical valve replacement and to examine the relationship between these two variables. Methods: This descriptive and cross-sectional study was conducted with 70 patients who underwent mechanical valve replacement in the Department of Cardiovascular Surgery of a university hospital between June 2024 and June 2025. Data were collected using the “Sociodemographic and Descriptive Characteristics Form,” the “Oral Anticoagulation Knowledge Test,” and the “Health Literacy Scale.” Independent sample t-test and one-way analysis of variance (ANOVA) were used for normally distributed variables, while the Mann–Whitney U and Kruskal-Wallis tests were used for non-normally distributed variables. Results: The mean age of the participants was 52.37±14.94 years (Min:18, Max:75), and 60% were male. Mechanical valve replacement was performed in 48.6% of the patients. The mean total oral anticoagulation knowledge test score was 13.31±3.13. The median total health literacy scale score was 119.0±11.83, with subdimension medians of 24.00±2.84 for access to information, 31.57±3.97 for understanding, 39.00±4.15 for appraisal, and 24±2.40 for application/use. A positive and statistically significant correlation was found between oral anticoagulation knowledge test total scores and the health literacy scale subdimensions of access to information (r:0.326, p:0.006) and appraisal (r:0.305, p:0.010). Conclusion: In this study, patients who underwent mechanical valve replacement had high levels of health literacy and moderately high knowledge levels regarding warfarin therapy. Moreover, a relationship was identified between health literacy-particularly in the access to information and appraisal subdimensions and knowledge about warfarin therapy. Accordingly, it is recommended to implement nurse-led, individualized, multidisciplinary educational programs using diverse teaching methods. Further studies with larger and more diverse samples are also suggested. Keywords: health literacy; knowledge level; mechanical valve replacement Supporting Organizations: None.

Özet

Mekanik Kapak Replasmanı Yapılan Hastalarda Sağlık Okuryazarlığı ve Warfarin Tedavisine İlişkin Bilgi Düzeyi: Kesitsel Bir Çalışma Öz Amaç: Bu araştırmanın amacı, mekanik kapak replasmanı yapılan hastalarda sağlık okuryazarlığı, warfarin tedavisine ilişkin bilgi düzeylerini değerlendirmek ve iki değişken arasındaki ilişkiyi incelemektir. Yöntem: Bu araştırma, tanımlayıcı ve kesitsel tiptedir. Araştırma, Haziran 2024-Haziran 2025 tarihleri arasında bir üniversite hastanesinin Kalp ve Damar Cerrahisi Anabilim Dalı’nda mekanik kapak replasmanı yapılan 70 hasta ile yürütülmüştür. Araştırma verilerinin toplanmasında “Sosyodemografik ve Tanıtıcı Özellikleri Formu”, “Oral Antikoagülasyon Bilgi Testi” ve “Sağlık Okuryazarlığı Ölçeği” kullanılmıştır. Normal dağılım gösteren değişkenler için bağımsız örneklem t testi ve tek yönlü varyans analizi (ANOVA) kullanılırken varsayımı sağlamayan değişkenler için Mann Whitney U testi ve Kruskal Wallis testi kullanılmıştır. Bulgular: Araştırmaya katılan hastaların yaş ortalaması 52.37±14.94 (Min:18, Maks:75) yaş olup %60’ı erkektir. Hastaların %48.6’sına mekanik kapak replasmanı yapılmıştır. Oral antikoagülasyon bilgi testi toplam puan ortalaması 13.31±3.13’tür. Sağlık okuryazarlığı ölçeği toplam puan medyanı 119.0±11.83 ve alt boyutları toplam puan medyanı bilgiye erişim için 24.00±2.84, bilgiyi anlama için 31.57±3.97, değer biçme/değerlendirme için 39.00±4.15 ve uygulama/kullanma için 24±2.40’tır. Sağlık okuryazarlığı ölçeği bilgiye erişim (r:0.326, p:0.006) ve değer biçme/değerlendirme alt boyutları (r: 0.305, p:0.010) toplam puan medyanları ile oral antikoagülasyon bilgi testi toplam puan ortalaması arasında pozitif yönlü istatistiksel olarak anlamlı bir ilişki saptanmıştır. Sonuç: Bu çalışmada mekanik kapak replasmanı yapılan hastaların sağlık okuryazarlığının yüksek ve warfarin tedavisine ilişkin bilgilerinin ise orta düzeyin biraz üzerinde olduğu saptanmıştır. Aynı zamanda sağlık okuryazarlığı bilgiye erişimi ve değer biçme/değerlendirme ile warfarin tedavisine ilişkin bilgileri arasında ilişki belirlenmiştir. Bu doğrultuda hemşire liderliğinde, bireyselleştirilmiş, faklı eğitim yöntemlerinin kullanıldığı, mutidisipliner ekibin yer aldığı eğitimlerin verilmesi önerilmektedir. Aynı zamanda benzer çalışmaların faklı ve daha büyük örneklemlerde yeni tekrarlanması önerilmektedir. Anahtar Kelimeler: mekanik kapak replasmanı; sağlık okuryazarlığı; bilgi düzeyi Destekleyen Kurumlar: Bulunmamaktadır.
