Computerized hospital discharge diagnoses are useful for occupational disease surveillance. One thousand one hundred twenty-six individuals with asbestosis and 268 individuals with silicosis were identified in New Jersey for the four-year period 1979-1982. Computer-generated maps help to dramatize t

Abstract
Economists have long used stateโcollected discharge data to construct HirschmanโHerfindahl (HH) indices measuring hospital competition. Since data are collected to determine the facility providing the service rather than ownership, the difference between the number of reporting facilities and the number of competitors has grown over time due to mergers and networking activities. Consequently, the validity of the discharge HH methodology, as currently employed, is in doubt. Comparing the annual census of New York state acuteโcare hospitals by the State and the American Hospital Association (AHA), we find that it is increasingly important to account for changes in ownership when constructing such indices.
