Một điển hình của thử nghiệm lâm sàng hiện nay chi phí những gì lãng phí không gian bắn vào những năm 1950. Chúng tôi không cần phải làm cho những sai lầm tương tự đã được thực hiện trở lại sau đó.

We needn t make the same mistakes that were made back then. Find the discrepancies and take advantage of the immediate availability of information that computer-assisted data entry provides to plug the holes as they arise. PAY FOR RESULTS NOT INTENTIONS The most expensive single item in any study today is the physician s fee. Well perhaps hospital charges can be appreciable as well. But you don t pay the hospital until after the surgery is completed and the patient discharged. Similarly do not pay the physician or specialty laboratories until all the completed forms are in hand.

CHAPTER 2 GUIDELINES 13 Part I PLAN We can t solve problems by using the same kind of reasoning we used when we created them.

Predesign Phase Form your design team see Chapter 4 . Your team s first step should be to decide whether the study is actually worth performing and whether you are ready to go forward. Do you have the information you need on dosage toxicity and cross-reactions with other commonly administered drugs Are the details of any necessary surgical procedure s standardized and commonly agreed on Do you know which if any categories of patients should be excluded from the trials Will the market for the drug device bioengi-neered formulation once these patients are excluded still .
