Document Summary
Clinical trials are studies designed to assess the efeciveness of clinical intervenions. Those undertaken to test innovaive therapies are oten designed in a series of phases: Phase iii trial, which may also be called a randomized clinical trial (rct) Usually involves use of large and heterogeneous sample of subjects, frequently selected from muliple, geographically dispersed sites to ensure that indings aren"t unique to a single seing. Evaluaions are used to ind how well a program/treatment/policy works. Generally, the term evaluaion research is used when they"re trying to determine efeciveness of a rather complex program, rather than when they"re tesing a speciic enity: thus, not all clinical trials would be called evaluaions. Evaluaions oten try to answer broader quesions than simply whether an intervenion is more efecive. Textbook notes: process analysis (or an implementaion analysis) obtains descripive informaion about the process of implemening a new program or procedure and about its funcioning in actual operaion.
