Günlük hayatta gerek tıbbi tedaviler veya cerrahi ameliyatların bir parçası olarak kan ürünleri nakli yapılmaktadır. Bu durum stok yönetiminin çok önemli olduğunu gösterir, zira ihtiyaç durumunda stokta istenen kan ürünü veya ürünleri yoksa hasta kaybedilebilir. Öte yandan kan toplamak sürekli bir çaba gerektiren bir eylemdir; bağışın gönüllü olduğu ülkelerde konfor, riskler, kolaylık ve erişilebilirlik gibi birçok faktör bağış kararını etkileyebilir. Ancak son yıllarda pandemi süreci nedeni ile dünyada olduğu gibi Türkiye’de de kan bağışları azalmıştır. Buna dış ülkelerden göçler de eklenince kanı tedarik etmek, kanı ürünlerine ayrıştırmak, depolamak ve hastalara zamanında ulaştırmak adına kan tedarik zinciri ve stok yönetimi her zamankinden daha da önemli hale gelmiştir. Kan tedarik zinciri, kan ve kan ürünlerinin donörden yani kan bağışında bulunan kişiden alıcıya yani kan ihtiyacı olan kişiye verilmesi, kan ürününü hastaya verilmeden önce özellikle bulaşıcı hastalıklar yönünden test edilmesi, ürünlerine ayrıştırmak için işlenmesi ve nihayetinde de ilgili hastane, sağlık merkezi, yoğun bakım üniteleri ve servislere dağıtılması süreçlerini içerir. Ancak koşullar ne olursa olsun kan talebini karşılamak için yeterli miktarda kan toplanması gerekir. Tedarik zinciri terminolojisinde arz ile talebin eşleştirilmesi, kan ve ürünlerinin toplanması, işlenmesi ve dağıtılması için iyi bir altyapıya ihtiyaç vardır. Kan tedarik zincirinin farklı konfigürasyonları, dünyanın farklı ülkelerindeki hastanelerde uygulanmakla birlikte amaç aynıdır yani kan ürünleri talebini minimum maliyet ve minimum israfla karşılamaktır. Bilim insanları farklı bakış açılarıyla konuyu ele almış bağış aşamasından hastaya nakil aşamasına kadar geçen süredeki her bir süreci iyileştirme adına değişik çalışmalar yürütmüşlerdir. Bu çalışmalardan en önemlileri sürecin simüle edilmesi ve tedarik zincirine yönelik yapılan araştırmalardır.

Blood Products Supply Chain

Öz

In daily life, blood products are transfused as part of medical treatments or surgical operations. This shows that stock management is very important, in case of need, if the desired blood product or products are not in the stock, the patient may be lost. On the other hand, collecting blood is an action that requires constant effort; in countries where donation is voluntary, many factors such as comfort, risks, convenience and accessibility can affect the donation decision. However, due to the pandemic process in recent years, blood donations have decreased in Turkey as well as in the world. When immigration from foreign countries is added to this, blood supply chain and stock management has become more important than ever in order to procure blood, separate it into its products, store it and deliver it to patients on time. The blood supply chain consists of giving blood and blood products from the donor to the recipient, that is, the person in need of blood, testing the blood product especially for infectious diseases before giving it to the patient, processing it to separate it into its products, and finally the relevant hospital, health center, intensive care units and distribution to services. However, whatever the circumstances, sufficient blood must be collected to meet the blood demand. In supply chain terminology, a good infrastructure is needed to match supply and demand, and to collect, process and distribute blood and its products. Although different configurations of the blood supply chain are implemented in hospitals in different countries of the world, the aim is the same, that is, to meet the demand for blood products with minimum cost and minimum waste. Scientists have dealt with the issue from different perspectives and carried out different studies in order to improve each process from the donation stage to the transfer stage to the patient. The most important of these studies are the simulation of the process and the researches on the supply chain.
