Voting behavior of HSA interest groups: a case study.

A study of the voting behavior of both consumers and providers involved on a Health Systems Agency (HSA) review committee was undertaken to determine the amount of voting cohesion (solidarity) demonstrated by these two basic interest groups as well as the directions in review decisions desired by both of these groups. The case study involved the application of the Rice Index of voting cohesion behavior to 23 decisions in one of the largest HSAs in the country. The conclusions reached are that: 1) consumers and providers do have differences in their intra-group voting cohesion, but that more importantly 2) they do not appear to be different with respect to the decisions (approve or deny) both groups desire for project reviews.
