Sağlıkta Blokzincir Benimsenmesine Yönelik Nedensel Haritalama ve Önceliklendirme

Öz

Bu çalışmada, sağlık alanında blokzincir benimsenmesini belirleyen etmenler Teknoloji–Organizasyon–Çevre (TOE) çerçevesi altında ve karşılıklı bağımlılıklar gözetilerek incelenmiştir. Literatürde öne çıkan on faktör arasındaki nedensel etkiler bulanık DEMATEL ile modellenmiş; on dört sağlık yöneticisinden elde edilen değerlendirmeler üçgensel bulanık sayılara dönüştürülerek bütünleştirilmiştir. Defuzzifikasyon ve normalizasyon sonrasında hesaplanan toplam ilişki matrisi üzerinden önem ve net etki göstergeleri türetilmiş; buna göre Uyum ve Güvenlik en güçlü itici unsurlar olarak belirlenmiş, Regülasyon Belirsizliği, Örgütsel Hazırlık, Yönetim Desteği ve Uygulama Maliyetleri ikincil sürükleyici etmenler olarak saptanmıştır. Birlikte Çalışabilirlik, Ekonomik Teşvikler, Karmaşıklık ve Ölçeklenebilirlik ağırlıklı olarak alıcı konumda gözlemlenmiştir. Nedensel ağın uzun dönem davranışını yansıtmak üzere DEMATEL çıktıları DANP ile öncelik ağırlıklarına dönüştürülmüş; birikimli etkinin Ekonomik Teşvikler ve Birlikte Çalışabilirlik üzerinde yoğunlaştığı gösterilmiştir. Bulgular, uygulanabilir bir sıralamaya işaret etmektedir: öncelikle uyum ve güvenliğin güçlendirilmesi, devamında birlikte çalışabilirlik ve ölçülebilir ekonomik değerin artırılması önerilmektedir. Bu çalışma, şeffaf ve tekrarlanabilir süreçleriyle, çeşitli hastane altyapılarına sorunsuz biçimde entegre edilebilen sağlam bir karar analitiği çerçevesi sunmaktadır.

Causal Mapping and Priority Setting for Healthcare Blockchain Adoption

Öz

Blockchain adoption in healthcare depends on how technical, organizational, and environmental conditions interact in practice. To produce a decision-oriented view rather than a descriptive list, the Technology Organization Environment framework is combined with fuzzy DEMATEL and DANP. Fourteen healthcare managers provided pairwise influence ratings across ten factors that were encoded as triangular fuzzy numbers, defuzzified, and normalized before computing the total relation matrix. The analysis separates drivers from receivers and then translates the causal map into steady state priorities. Compliance and Security emerge as upstream drivers that influence the direction toward Interoperability and Economic Incentives. The DANP weights concentrate on these two outcomes, indicating where benefits accumulate when upstream levers are activated. The main implication is operational: start with compliance by design and security controls, backed by explicit leadership sponsorship and organizational readiness. Then, target interoperability and measurable economic value while reducing complexity and improving scalability. The workflow is reproducible in typical healthcare settings and can be replicated with the materials described in the paper.
