Add slider item to question

In Study Designer, study teams have a variety of tools to configure case report forms (CRFs) for data collection. There are various items— text fields, checkboxes, dropdown menus, date pickers, and more—that you can add as form fields next to their respective questions. You can place these fields on the form canvas, arrange them as needed, and make sure they are associated with the corresponding variables. This provides flexibility to outline the way each question must be answered by the user, and how the data must be stored by the system.

One of the items that you can add to the form questions is a slider. Sliders are most appropriate when the collected data is continuous or falls on a numeric scale. Sliders provide a visual representation of a range, allowing healthcare professionals who enter data in EDC or users of the eDiary and eCOA apps to select a specific point within that range.

For example, if you are collecting pain intensity ratings on a scale of 0 to 10, a slider can be used to capture the exact point on the scale.

To add a slider item to a question

  1. In the Study Designer application header, select the CRF DESIGN tab.

  2. In the toolbar, select the latest draft CRF version marked with the respective unlock symbol unlocked_icon_purple.png, otherwise, you cannot perform any actions.

    Element

    Details

    Data Type*

    Select the type of data that is to be collected for a corresponding question. The data type is usually preselected by the system but can be changed depending on the allowed data types for the selected CDASH variable.

    Length*

    Enter the maximum number of characters or digits that the field can capture when entering data in EDC. The length is usually defined by the system according to the selected CDASH variable but can be updated.

    CDASH Variable*

    Enter the name of the CDASH variable that is to capture data specified in a corresponding field in EDC. You can either select one of the available domain variables or enter a name for the custom one. The field only supports uppercase letters, numbers, and underscores.

    CDASH Label*

    Enter the label for the CDASH variable that is to capture data entered in a corresponding field in EDC. The label is usually defined by the system according to the selected CDASH variable but can be updated.

    RecordID*

    Enter the record number that enables different fields on the form associated with the same variable to capture data records in separate rows. These records will be presented accordingly in the output dataset upon data entry in EDC.

    For example, in the Vital Signs form, you have the questions "Pulse", "Temperature", and "Respiratory Rate". The text item is assigned to all three questions and it is specified that the VSORRES variable is to capture the corresponding data.

    In order to distinguish the collected vital sign results in a more organized manner, you can assign "record ID = 1" to the text item of the "Pulse" question, "record ID = 2" to the text item of the "Temperature" question, and "record ID = 3" to the text item of the "Respiratory Rate" question. In such a way, the captured results will be displayed in separate record rows in the output dataset.

    Moreover, you can enter record IDs separated by commas if you want the specific data point to repeat in the output dataset.

    For example, you can specify record ID = 1,2,3 for the label item Predose assigned to the Time Point question in the same Vital Signs form. This item is associated with the VSTPT variable which means that the Predose label will be displayed in 1, 2, and 3 record rows along with the pulse, temperature, and respiratory rate vital sign results.

    SAVE

    Select save_button_red_white.png to add the item with the specified variable definition to the question.

    CANCEL

    Select cancel_button_white_blue.png to cancel adding the item.

Once saved, the slider item is added to the form question. You can now continue to maintain forms with available actions.

A specialized document in a clinical trial designed to collect the subject data.

See also eCRF.

An individual piece of data collected within a domain. It represents a specific attribute or characteristic that can vary among subjects in a study. Each variable is defined by its format (such as categorical, continuous, and so on) and plays a crucial role in data analysis, allowing researchers to assess relationships and outcomes in the study.

For instance, within the "Demographics" domain, variables might include "Age," "Gender," and "Ethnicity."

An eClinical application that is mainly used to collect and manage subject data during clinical trials. It integrates with the Study Designer (SD) application and uses preconfigured there case report forms (CRFs) to complete data collection and management. It also provides an audit trail, data alert, source data verification (SDV), payment management, adjudication, and other functions as well as supports data export according to the CDISC ODM standard.

Get to know all the possibilities of the app with the comprehensive EDC User Guide.

An eClinical mobile application used for the collection and management of clinical data of subjects, supporting iOS and Android systems. It is based on the electronic CRF provided by the Study Designer application to support subjects' self-recording of treatment and diagnosis information.

An eClinical mobile application designed for the collection of clinical outcome assessments, such as patient-reported outcomes, questionnaires, and other data related to the participant's health, symptoms, or treatment experiences.

A process of ensuring data accuracy and integrity within a clinical trial. SDV involves the review and comparison of data recorded in the source documents against the data captured on the case report forms (CRFs). During SDV, a trained monitor or clinical research associate (CRA) compares the source data to the CRFs to identify any discrepancies or errors. They may review laboratory results, medical history, adverse event records, and other relevant information. Discrepancies found during SDV are usually documented and resolved through data clarification or query processes with the site personnel responsible for data collection.

A person responsible for managing and ensuring the integrity, accuracy, and confidentiality of data collected during clinical trials. The DM’s scope of work might include maintaining the quality of data, complying with regulatory requirements, and supporting the overall success of clinical research.

In the eClinical system, the Data Manager (DM) user role is granted to a person who is mainly responsible for cleaning the data, making sure the data is entered correctly according to all requirements and industry standards, and creating manual queries for clinical research coordinators on any questionable data pieces. Before the study goes live, works with the sponsor and receives and addresses their feedback to set up the study and CRFs in EDC in a way that the sponsor approves.

A person responsible for overseeing and monitoring a clinical trial to ensure it is conducted in compliance with regulatory standards and protocols. The CRA’s scope of work might include protocol review, site selection and initiation, monitoring, data entry control, and more.

In the eClinical system, the Clinical Research Associate (CRA) user role is assigned to a person who works with the sites, and in EDC, mainly has to make sure that the entered data is truthful to the source document. CRA checks the source document in a process called source data verification and ensures that everything entered by the clinical research coordinators is valid to avoid any discrepancies caused by human errors.
