Computer-implemented process of reporting injured worker information
Predefined lists of selected variables are created and interrelated to produce incident reports. The lists are created and modified through the use of formatted computer screens or input forms, and the reports are produced through the use of formatted computer outputs or output formats. The lists include accident-related information such as industry types, occupations, safety teams, attendance codes, types of injuries, body parts affected, types of incidents, site conditions, accident causes and safety reminders. The input forms often correspond directly to the types of lists, so that there is a form through which the list of industry types is created and / or modified, and another form through which the list of occupations is created. In addition, there are input forms that allow creation and / or modification of several lists at one time, particularly when each element in one list is directly associated with one element from another list. The output formats include agency-related formats such as an OSHA (Occupational Safety & Health Administration) No. 200 report, and statistical summaries used for managerial decision making. The statistical summaries may be textual or graphical, or a combination of textual and graphical.
