Tables in Emergency Department Trends From DAWN

Tables in ED Trends From DAWN follow a 3-part numbering scheme, with each of the 3 terms separated by periods (e.g., Table 2.2.0). The first (beginning) and third (ending) terms have specific meaning.

• Table numbers beginning with:

  1. contain information about the ED sample and the precision of the estimates.

  2. through 5. contain estimates of ED episodes and ED drug mentions.

  12. through 14. contain corresponding rates per 100,000 population.

  Each table of estimates has a corresponding table of rates per 100,000 population, designated by a 1 prefix added to the table number. For example, Table 2.3.0 contains estimates of ED mentions for major substances of abuse; Table 12.3.0 contains population-based rates of ED mentions for the same major substances of abuse.

• Table numbers ending with:

  .0 contain estimates for the coterminous U.S.

  .1 through .21 contain estimates for the 21 metropolitan areas oversampled in DAWN, where .1 is Atlanta, .2 is Baltimore, … .21 is Washington, DC (see below).

  No third term (e.g., 3.1, 3.2, 13.1, 13.2, etc.): These tables contain summaries for all the metropolitan areas in DAWN. For example, Table 3.1 summarizes total ED episodes across the 21 metropolitan areas.

• RSE tables follow the same numbering scheme, with a prefix of RSE attached to the companion table number. For example, Table RSE-2.2.0 contains the RSEs for the estimates published in Table 2.2.0.

• Tables 2.3.x through 2.12.x enumerate the specific substances in 5 categories:

  2.3.x and 2.4.x – Major substances of abuse (half year and full year estimates, respectively; e.g., for cocaine, heroin, marijuana, "club drugs")

  2.5.x and 2.6.x – Psychotherapeutic agents (e.g., benzodiazepines)

  2.7.x and 2.8.x – Central nervous system (CNS) agents (e.g., narcotic analgesics)

  2.9.x and 2.10.x – Respiratory agents (e.g., antihistamines)

  2.11.x and 2.12.x – Cardiovascular agents (e.g., beta-adrenergic blocking agents)

  Corresponding population-based rates are found in Tables 12.3.x through 12.12.x.

• Tables 3.x (13.x) summarize ED estimates (rates) across the 21 metropolitan areas.

• Tables 4.1.x (14.1.x) through 4.34.x (14.34.x) summarize DAWN ED cases by patient demographics.

• Tables 5.1.x through 5.34.x summarize DAWN ED cases by episode characteristics. No population-based rates are produced for episode characteristics.
