We have developed a simple and user friendly electronic Data Entry Management System (DEMS) to ensure secure, easy and accurate data collection obtained from the members of the participating centers.

Please click on the icon below to download the printer friendly PDF version of the instructions:

1. Login to the website to access all necessary study documents and submit your cases online. To do so, click on the “Login” button available on the top right side of the website (see image below) or simply use the following link: https://www.oltbenchmarks.org/user

   

   Your account login details including your username and password were provided to your by email sent from our study coordinator, Dr. Xavier Muller  (Xavier.Muller@usz.ch) at the University Hospital Zurich (see bellow how to contact us). If for any reason you did not receive this email, please check your spam folder or contact Dr. Xavier Muller to send it to you again.

   
    

2. Please ensure that you have carefully read the study protocol before attempting entering cases at our Data Entry Management System (DEMS). To do so, please click on the “Protocol” icon shown as shown below. The link to the protocol is also available on the main menu and right side bar of the website in all pages. Alternatively you may directly access the study protocol using the following link: https://www.oltbenchmarks.org/protocol

   

   
    
3. To start submitting your cases to our electronic Data Management System (DEMS) please click on the link “Data Entry” or “Submit Cases” links available on the platform as shown below:

   
    

4. The Data Entry Management System (DEMS) consists of a simple electronic form that you may fill in the data for each case (see image below). Please ensure to complete as much information as possible / available. The DEMS can be also accessed directly using the following link: https://www.oltbenchmarks.org/DEMS

   Fields including a red star at the end of the name of the parameter (*) are mandatory to be able to submit each case. For example, each case should be assigned with a unique Case ID, the first field in the form shown below. If this information is missing, you will not be able to submit the case.

   

   The second and last mandatory field for the successful electronic submission of a case is the “Complications types and grades according to the Clavien-Dindo Classification from transplantation until discharge *” under the section “Recipient complications from transplantation until discharge”.

   This field is mandatory as it is the primary endpoint of this study! If the recipient did not encounter any complications from transplantation until discharge, please indicate "None" for all types and grades of complications (see image below):

   

   This table (grid) shown in the image above was created to record with a single click the type of as well as the grade of the same complication according to the Clavien-Dindo Classification of Surgical Complications. The rows correspond to specific types of complications and the columns to their associated grade.

   For example, if in a case there was bleeding that was managed surgically, the complication would be Grade IIIb as shown below:

   

   Please ensure you included all types and grades of complications in this table.

   For additional types of complications not listed in the table (i.e. other rather than bleeding, biliary, infection, ascites) please grade them according to the Clavien-Dindo Classification of Surgical Complications under the parameter names: “Other A”, “Other B” “Other C” and so on, as shown below:

   

   Please ensure that you describe in detail the types of “Other” complications as well as how they were treated in the free text option as shown above. If a case was not associated with any complications, please click on “None” for all types of complications listed in the table above.
    

5. Please ensure to click on the “Submit” button at the end of the form to successfully submit each case you added data for as shown below:

   

   
    
6. Please click on the “Submit” button only once and wait until your receive the confirmation shown below:

   

   
    
7. To submit the next case, click on the “Go back to the form” link shown above or click on the “Data Entry” link available in the main menu or the right side bar of the website.
    
8. If for any reason you would like to access the list of your previous case submissions, please click on the “View your previous submissions.” links available on the top of the form as shown below:

   

   Then you will be provided with the list of cases (only the ones that you have submitted) where you may view or edit again, as shown below:

   
   Please ensure to save your changes by clicking on the “Submit” button at the end of the page.
    

9. We have also made available for your convenience and to ensure unified and accurate data collection several online calculators and blood unit converters available on the right side bar of the website (after having first logged in) as shown below.

   

   If you are not familiar with the Clavien-Dindo Classification of Surgical Complications, the parameter associated with the primary endpoint of the study, please ensure that you have first read and understood clearly the different grades available at the link “Clavien-Dindo Classification” as shown above.
