“…In the study by Moran et al ., 57.7% of patients were unaware of any potential adverse effects after being educated about warfarin . The percentage of participants being aware of any adverse effects (one or more) was therefore higher in the present study.…”

“…This might be because the issue of drug interactions was not being reiterated by other health professionals, including the doctor, community pharmacist or nurse, as extensively as necessary during the 6 weeks follow‐up. Existing literature suggests drug interactions being poorly recalled by patients, with Smith et al . reporting 17% of their study population being aware of drug interactions .…”

“…A positive correlation has been demonstrated between patient knowledge of warfarin after education by physicians, nurses and pharmacists and the number of International Normalised Ratio (INR) values measured to be within the target range . Literature addressing the extent of patient retention of information on warfarin generally suggests poor information recall, particularly with regard to understanding the impact of the vitamin K content of food on warfarin action and awareness of drug interactions with warfarin (with studies including patients continuing pre‐admission warfarin therapy as well as being newly initiated on warfarin) . One study concluded that only 23% of participants were aware of diet interactions …”

“…Other studies report poor recall of drug interactions with warfarin, ranging from 17% to 52.1% of respondents being aware of drug interactions . Research findings suggest that nearly 58% of patients were unaware of any potential adverse effects . The majority of literature addresses warfarin education by pharmacists or physicians, with some literature exploring warfarin education by nurses.…”

Background Patient education delivered through pharmacist counselling is important in promoting the safe and effective use of anticoagulants. Aim To evaluate the extent to which patients retain information after counselling from a clinical pharmacist about the anticoagulant warfarin; to perform a brief analysis of the cost‐analysis of warfarin counselling; and to investigate relationships between case‐specific characteristics and patient outcomes. Method A total of 22 patients was recruited. Eligibility criteria included age ≥18 years, new initiation of warfarin in hospital, intact cognition and an expectation of self‐administration of warfarin after discharge. Key elements of knowledge were assessed immediately after counselling and 6 weeks after counselling. The duration of each counselling session was recorded as a surrogate for costs involved, and case‐specific characteristics were documented. Results Participants demonstrated an ability to recall an average (mean ± standard deviation) of 79.9 ± 14.6% of key information elements immediately after counselling, significantly higher than was observed 6 weeks after counselling (71.0 ± 11.7%; p = 0.02). The percentage of participants achieving an ‘acceptable’ score for knowledge was 68.2%, both immediately after counselling and 6 weeks later. No significant relationships between specific case characteristics and patient outcomes, duration of counselling or overall warfarin knowledge retention scores 6 weeks after counselling were demonstrable. Conclusion These findings imply that more emphasis should be placed on educating patients on the critical information elements for warfarin counselling. Further research is required to explore potential relationships between case‐specific characteristics and patient outcomes, as well as the costs associated with the counselling process.

“…[26] Warfarin en sık ilaç etkileşimi görülen ilaçların başını çekmesine ve her yıl yeni ruhsat alan ilaçlarla potansiyel etkileşimler artmasına rağ-men [27] OAT alan hastaların %30-75 oranı ile en az bildikleri konulardan biridir. [10,12,28,29] Biz bu ankette ilaçları ayrıntılı sorgulamadan yalnızca ilaç etkileşimi bilgisini araştırdık ve ilaç etkileşiminden haberdar hasta oranını çok düşük olarak saptadık. Diğer konularda saptamış olmamıza rağmen bu konuda bilgilendirme ile ilişki saptamadık.…”

SUMMARY Objectives The aim of this study was to assess current knowledge of patients receving oral anticoagulant therapy (OAT). Methods Patients ÖZET AmaçBu çalışmanın amacı, herhangi bir nedenle oral antikoagülan tedavi (OAT) alan hastaların tedavileriyle ilgili bilgilerinin ve ilişkili faktör-lerin değerlendirilmesidir. Gereç ve YöntemBu anket çalışmasında, erişkin acil servise başvuran ve OAT aldığı saptanan hastalardan ankete katılmayı kabul edenlere çalışmacılar tarafından hazırlanan anket uygulandı. Demografik özellikler, ilaç bilgisi ve OAT tedavisiyle ilgili bilgilendirilme durumları incelendi. OAT bilgisine etkili faktörlerin karşılaştırılmasında ki-kare testi kullanıldı. BulgularÇalışmaya katılan 122 hastanın yaş ortalaması 64±14, %37.7'si erkek, %51.6'sı >65 yaş, %33.6'sı hiç öğrenim görmemişti. Hastaların %61.5'i (n=75) OAT ile kanama riski olduğunu, %70.5'inin (n=86) düzenli kan tetkiki yaptırması gerektiğini bildiği saptandı. Çalışma grubunun %15.6'sı (n=19) OAT'nin diğer ilaçlarla, %10.7'si (n=13) yiyeceklerle etkileşimi olduğunu biliyordu. Hastaların %64.8'i (n=79) daha önce OAT konusunda bilgilendirildiğini bildirdi. OAT' yi reçete eden hekim hastaların %27'sinde (n=33) bilgi kaynağı olarak saptandı. Altmış beş yaş ve altı ile 65 yaş üstü hastalar arasında kanama riski (p=0.002) bilgisinde fark bulundu. Öğrenim görmüş olan ve olmayan hastalar arasında kanama riski (p=0.011), ilaç etkileşimi (p=0.049) ve diyet etkileşimi (p=0.034) bilgisinde fark saptandı. Daha önce OAT konusunda bilgilendirilmiş hastalar ile bilgilendirilmemiş hastalar arasın-da kanama riski (p<0.001), tetkik gerekliliği (p<0.001) bilgisi arasında fark bulunmasına rağmen ilaç etkileşimi (p=0.095) ve yiyecek etkileşimi (p=0.54) bilgisi arasında fark bulunmadı. SonuçOral antikoagülan tedavi başarısızlığının komplikasyonları göz önü-ne alındığında OAT bilgi ve bilgilendirilme düzeyleri düşük bulunmuştur. Hekim ve hastaların OAT bilgi düzeylerinin arttırılması gerektiğini düşünüyoruz.
