An analysis of selected blood service policy changes.

Prinicipal national goals for a blood service system are concerned with shortage, quality, acessibility, and efficiency. Since regional blood service operating objectives based on these goals are in partial conflict, a single policy does not exist. Using a computer-based planning system, four policies are examined and tested for their effects on these objectives. [corrected] The policies are: use of frozen red cells ( a technological alternative); extension of the useful life of fresh blood (a legal alternative); improved collection planning (a planning alternative), and improved inventory management (a management alternative). Model projections of the effects of each policy and comparative performance of each policy with respect to the principal objectives are discussed.

A computer-based interactive planning system for scheduling blood collections.

Seasonal imbalances between supply and demand for blood products are common. This paper describes a planning system which utilizes conversational computer facilities to assist the manager of a regional or communitywide blood agency in scheduling bloodmobiles and fixed facility collections from one to 18 months in advance. The benefits from changes to only one day of a collection schedule recover the annual costs of using the system, estimated at at $600 for a blood service which collects 65,000 units annually.

Cost effectiveness of use of frozen blood to alleviate blood shortages.

Human blood shortages are a perennial problem because of the relatively short life span (21 days) of stored blood and the traditional shortage periods during summer vacation months and other vacation periods. This study evaluates the use of frozen blood during these traditional shortage periods. An empirically-based simulation model is used. During periods of excess supply surplus blood is frozen and during shortage periods frozen blood is thawed and used as a substitute for stored blood. The results of the study indicate that the use of frozen blood during shortage periods alleviates shortages but at a high cost. Improved blood collection scheduling management and promotion will attain the same results at a lower cost.
