Logical Data Model

Information about actual or reported immunization. <br/><br/>For reported rather than actual-event information, i.e. where Reported Information is specified (as a relationship end), instead of Immunization Event: if specific attribute values are not available, corresponding free text descriptions can be entered instead, either in the free text field of the attribute (every logical data type has such a field) or in clinical notes. <br/><br/>Since reported information is provided by a non-practitioner, expectations about its accuracy are low, unlike for actual (immunization) event information whose source is a health care practitioner or a computer record. Thus, although the information may sometimes be accurate (e.g., when a patient has access to prescriptions or to the report of a vaccination performed in a clinic), it may also be incomplete and inaccurate, as some patients may not recall their medical history precisely.<br/>
