Recommended Variables for the Multiple Stratification of General Hospitals


Some characteristics of short-term general hospitals are examined in order to determine which variables, among those for which data are readily available, might be most useful for stratification when multipurpose samples of United States hospitals are to be selected. Illustrative tabulations are presented in which 1961 AHA data on 5078 general hospitals, grouped by hospital control and four approval classes, are distributed in six size classes, four geographic regions, three SMSA classifications, and nine geographic divisions. The tables and the recommendations based on them should be of value to those planning hospital studies when resources and time available for designing a sample are limited.
