Facility-level compliance rates with recommended preventive services based on the 1999 nationwide Veterans Health Survey. Percentages indicate the percent of respondents who received recommended services within an appropriate time frame at either the VHA or at a non-VHA facility.

^*Hospital-level benchmarking scores were developed by ranking adherence rates for each of the 12 services relative to other hospitals, and converting the ranks to percentile scores. A value of 1 was assigned if the hospital performed above the 50th percentile for a given service, and a value of 2 was assigned if the hospital performed above the 75th percentile. Scores for each service were summed to determine each hospital's benchmarking score.
