Overview
A report template defines a subject clinic report. It can be a combination of formatted text, variable values, and JavaScript code. A subject report is run from the "Reports" tab, which is on the right half of the "Subject Overview" page's "Details" view.
...
To access a subject's variable value in the report, use the following syntax: <%= #VarCode %>, where <%= %> is the syntax used to indicate that a subject's variable value is to be placed in this location, and #VarCode is a "#" prefixed to a variable's code. If the variable is a categorical variable, the pick list display name for the variable's value can be accessed with the following syntax: <%= #VarCode.Name %>.
Report Types
There are two basic types of reports: those tied to intervals and those global to a subject. Create a report tied to intervals if you wish the report to be run for a particular encounter. In the Reports tab of the Subject Overview page, the reports tied to intervals will be available to run for every encounter the subject has for the report's associated intervals. When the report is run, it will use the variable values from the selected encounter for the encounter variables defined in the report.
...
If a report does not access any encounter variables directly, it will not be associated with any intervals. In the Reports tab of the Subject Overview page, these reports will be listed under Project Reports.
Incorporating JavaScript Code
Most reports can be created without writing any JavaScript code. However, if the report includes complex calculations or needs access to encounter data other than the encounter it is being run against, JavaScript is required. To add JavaScript code to the report, enclose the code within the following symbols: <% %>

Assuming a value of "0.45" for the variable "notBmi", the following will be the output: My incorrect BMI calculation is 0.45
Null Objects
A null object is returned whenever the referenced object (encounter or medication) cannot be located. The null objects allow you to access the object as if one were found making it much easier to create reports. Null objects are returned for encounters and medications.
Encounter Object
Properties
- EncounterDateObject – The date value of the encounter. Will return DateTime.MinValue if the encounter is null.
- EncounterDate – the string value of the encounter. Will return an empty string if the encounter is null.
- IsBaseline – returns true if the encounter is the baseline encounter, otherwise false.
- IsFixed – returns true if the encounter is for a fixed interval, otherwise false.
- IsNull – returns true if the encounter is null, otherwise false.
- #DataExportName – returns the value of the variable with the specified data export name. If the value is null, an empty string is returned.
- #DataExportName.Name – returns the pick list name associated with the value of the variable with the specified data export name. If the value is null, an empty string is returned.
- #DataExportName.ID – returns the ID of the variable with the specified data export name. This is used for methods that take a variableId.
Methods
- GetVariableLabel(variableId) – if the variable is categorical (pick list or radio buttons), it will return the display name, otherwise it will return the value of the variable.
Encounter Collection (ENCOUNTERS)
Overview
Data (including variable values) about any of the subject's encounters can be accessed via a special object named "ENCOUNTERS". This object is a collection of "Encounter" objects (described above). Following is an example of using this collection in code:
...
To access encounter variables, either loop through the ENCOUNTERS collection or use one of the properties or methods described below to obtain a reference to an Encounter object. At that point you can access a variable value with the encounter.#den syntax as described above.
Properties
- Count – returns the number of encounters in the collection.
- FirstEncounter – returns the first encounter in the collection. If no encounter is found, a null encounter is returned.
- LastEncounter – returns the last encounter in the collection. If no encounter is found, a null encounter is returned.
Methods
- Average(variableId) – returns the average value of the variable specified by variableId for all encounters in the collection. Returns NaN if any values are null.
- Sum(variableId) – returns the sum of the variable specified by variableId for all encounters in the collection. Returns NaN if any values are null.
- Filter(variableId, compareOperator, compareValue) – returns a collection of encounters that are not excluded by the specified filter. The valid values for compareOperator are:
- IS NOT NULL
- IS NULL
- =
- !=
- <>
- <
- <=
- >
- >=
- GetCount(variableId) – returns the number of encounters in the collection that have a non-null value for the specified variableId.
- GetEncounter(encounterDate) – returns the first encounter in the collection with the specified encounterDate if found, otherwise it returns a null encounter.
- GetEncounter(encounterDateString) – attempts to convert the string to a date and then returns the first encounter in the collection with the specified encounterDate, if found, otherwise it returns a null encounter.
- GetEncounter(index) – returns the encounter at the specified index in the collection. If the index is greater than the number of items in the collection, a null encounter is returned.
- GetFirstEncounter()- returns the same as the FirstEncounter property. If no encounter is found, a null encounter is returned.
- GetNextEncounter(encounterObject) – returns the encounter in the collection that follows the specified encounter. If no encounter is found, a null encounter is returned.
- GetNextEncounter(encounterDate) – returns the encounter in the collection that follows the encounter with the specified date. If no encounter is found, a null encounter is returned.
- GetNextEncounter(encounterDateString) – attempts to convert the string to a date and then returns the encounter in the collection that follows the encounter with the specified date. If no encounter is found, a null encounter is returned.
- GetPriorEncounter(encounterObject) – returns the encounter in the collection that precedes the specified encounter. If no encounter is found, a null encounter is returned.
- GetPriorEncounter(encounterDate) – returns the encounter in the collection that precedes the encounter with the specified date. If no encounter is found, a null encounter is returned.
- GetPriorEncounter(encounterDateString) – attempts to convert the string to a date and then returns the encounter in the collection that precedes the encounter with the specified date. If no encounter is found, a null encounter is returned.
- IndexOf(encounterObject) – returns the index of the specified encounter object. If no encounter is found, a null encounter is returned.
- IndexOf(encounterDate) – returns the index of the first encounter with the specified encounterDate. If no encounter is found, a null encounter is returned.
- IndexOf(encounterDateString) – attempts to convert the string to a date and then returns the index of the first encounter with the specified encounterDate. If no encounter is found, a null encounter is returned.
- MaxEncounter(variableId) – returns the first encounter in the collection containing the max value for the specified variableId. If no encounter is found, a null encounter is returned.
- MaxValue(variableId) – return the max value for the specified variableId. An empty string is returned if no values are found.
- MinEncounter(variableId) – returns the first encounter in the collection containing the min value for the specified variableId. If no encounter is found, a null encounter is returned.
- MinValue(variableId) – return the min value for the specified variableId. An empty string is returned if no values are found.
- Offset(encounter, offset) – returns the encounter that is offset positions away from the specified encounter. If no encounter is found, a null encounter is returned. Offset can be negative. Ex.
// returns the second to last encounter.
ENCOUNTERS.Offset(ENCOUNTERS.LastEncounter, -1)* Offset(encounterDate, offset) – returns the encounter that is offset positions away from the encounter with the specified Date. If no encounter is found, a null encounter is returned. Offset can be negative. - Offset(encounterDateString, offset) – attempts to convert the string to a date and then returns the encounter that is offset positions away from the encounter with the specified Date. If no encounter is found, a null encounter is returned. Offset can be negative.
- Sort(variableId, ascending) – returns a collection of encounters sorted by the values of the specified variableId. If ascending is true, the collection will be sorted in ascending order, otherwise it will be sorted in descending order.
