3M has developed a composite measure, a 3M Value Index Score, which provides a standard metric to assess accountable value in health care. This index care domains derived from 16 measures of key processes and outcomes that effect value in health care. According to 3M, this Value Index Score can increase the understanding f provider and system performance thereby accelerating and prioritizing the areas where improvement is needed. This measure can be used by both providers and payers to help improve patient outcomes and to control costs. Suppose you were asked to develop a sampling plan for a study to determine the value index, and general attitudes toward the index, what sampling plan would you use? What is the target population(or are there multiple target populations)?Which of the four types of random sampling discussed in the chapter would you use and why? If you were to use stratified random sampling, what would be your strata?
