viewTrial

viewTrial provides a template R shiny web application that can be used for centralized monitoring in clinical trials and research.

To use the template

You could clone this repository to your local machine to copy the template code.

Structure of the app

The app has been developed in a modular fashion as an R-package in which each module represents a tab in the sidemenu.

List of modules

The tabs are categorised under two major sections, "Performance measures" and "Study management".

Performance measures

• Recruitment mod_recruitment provides a recruitment plot together with two information boxes.

• Retention mod_retention details loss to follow up.

• Data quality

  • Completeness mod_completeness provides an example of how data completeness might be shown
  • Timeliness mod_timeliness provides an example of how time between events and their entry into the database might be shown
  • Queries mod_queries provides an example of how queries might be shown

Study management

Aspects of study management can also be depicted via Shiny.

• Follow-up visits mod_fup provides an example of how tracking of participant progress through a trial might be shown

• Safety management

  • Serious adverse events mod_sae counts of SAEs

Extending the app

For example, let's add a module called "Home" to the app.

1. Copy and rename the file mod_skeleton.R.

file.copy("R/mod_skeleton.R", "R/mod_home.R")

2. Adapt the file "R/mod_home.R" by renaming the UI and server functions and adding content.

3. Create a module alias by adding the line home = "mod_home", to R/get_modules.R.

4. Add the line menuItem("Home", tabName = mod$home, icon = icon("home")), to R/ui.R within sidebarMenu(). Icons of choice can be selected from https://fontawesome.com/icons and https://getbootstrap.com/docs/3.3/components/#glyphicons.

5. Add the line mod_home_ui(mod$home, label = mod$home), to R/ui.R within dashboardBody().

6. Add the line callModule(mod_home_server, mod$home) to R/server.R within app_server().
