title: Should the audiometric database analysis method (draft ANSI S12.13-1991) for evaluating the effectiveness of hearing conservation programs be accepted as a US national standard?.
abstract: The value of audiometric database analysis (ADBA) procedures for evaluating the effectiveness of hearing conservation programs (HCPs) was studied in a population of 82,195 workers. We rated the HCP using four ADBA procedures. Results showed that the HCP ratings ran the gamut from "unacceptable" to "acceptable" from year to year and from procedure to procedure. A mere 7 percent of the total population was eligible for ADBA analysis. This drastically reduced sample size precludes subgroup analyses of even a large cohort and likely could not be applied to the HCPs of most small- and medium-sized businesses. The low levels of agreement observed (weighted kappa = 15%-25%) between the ADBA procedures reflect poor validity. Generalizability of these results would be inappropriate when so few nonrandomly selected individuals contribute to the evaluation. In view of these problems, acceptance of the ADBA method as a national standard may not be warranted.
