Figure C1 is titled "DAWN ED case form." It is a copy of the form used by hospital recorders to collect information about DAWN ED visits, with the following note below the image: "SMA 100-1 Rev. 12/2005." The major data items collected are: facility ID, date of visit, time of visit, age, patient's home ZIP code, sex, race/ethnicity, diagnosis, case description, substance(s) involved, route of administration, type of case, disposition.

Figure C2 is titled "Type of case decision tree." It is a flow chart, with the following note below the chart: "Rev. 12/12/2005." The flow chart shows the path taken to decide the case type of a drug-related ED visit. The first case type that applies is the case type assigned. After deciding a visit is a DAWN case, the first applicable case type from the following list is applied to the visit: suicide attempt, seeking detox, alcohol only (age < 21), adverse reaction, overmedication, malicious poisoning, accidental ingestion, other.

Figure C3 is titled "Original DAWN sample design". The figure consists of a large rectangle that represents all DAWN eligible hospitals. The large rectangle is divided vertically into two smaller rectangles, one on the left that represents the remainder sample hospitals, and a further subdivided rectangle on the right that represents the oversample area hospitals. The oversample area rectangle is partitioned by a grid that has two columns and nine rows. The first column represents the dual-purpose hospitals while the second column represents the oversample hospitals. Each row in this grid represents a different OS Area.

The remainder sample hospitals rectangle contains numerous black stars that each represent an individual hospital in the remainder sample. Some but not all grid cells within the dual-purpose hospital column contain striped stars that each represent an individual dual-purpose hospital. All grid cells in the oversample hospital column contain white stars that each represent an individual oversample hospital that is not dual-purpose.

Figure C4 is titled "DAWN design in practice". The figure consists of a large rectangle that represents all DAWN eligible hospitals. There is a legend below the rectangle indicating that white stars represent oversample hospitals; black stars represent remainder-sample hospitals; a grey background represents areas in stand-alone oversample estimates; and a white background represents areas in remainder estimate. The large rectangle is divided vertically into two small rectangles, one on the left that represents the remainder sample hospitals, and a further subdivided rectangle on the right that represents the oversample area hospitals. The oversample area rectangle is partitioned by a grid that has two columns and nine rows. The first column represents the dual-purpose hospitals while the second column represents the oversample hospitals. Each row in this grid represents a different OS Area.

The top 6 rows of the oversample areas grid are shaded in grey and represent the oversample areas that are standalone and are used in the stand-alone oversample estimates. The rest of the large rectangle has a white background representing the union of oversample areas that are not standalone and the remainder areas which are used in the remainder estimate.

The remainder sample hospitals rectangle, with a white background, contains numerous black stars that each represent an individual hospital in the remainder estimate. Some but not all grid cells within the dual-purpose hospital column, where the background is white and consists of the bottom 4 rows of the oversample areas grid, also contain black stars that each represents an individual dual-purpose hospital used in the remainder estimate. The grid cells in the oversample hospitals column are empty of any stars since only dual-purpose hospitals are used in the estimates for non-stand-alone OS areas. Some but not all grid cells within the dual-purpose hospital column, where the background is grey and consists of the top 6 rows of the oversample areas grid, contain white stars that each represents an individual dual-purpose hospital used in the OS areas estimates. All grid cells in the oversample hospital column, where the background is grey, also contain white stars that each represents an individual oversample hospital that is not dual-purpose and that is also used in the OS area estimates.
