The organizer provides a convenient bed rail mounted carrier for patient items. The organizer uses integral press-fit clamp members that capture the bed rail to securely hold the assemblies to the bed rail. In certain embodiments, the organizers may take the form of a unitary rail caddy for holding various personal items, such as telephones and remote controls. In other embodiments, the organizers may take the form of a modular tray and caddy assembly with interchangeable components, such as mounting bases, tray tops and accessory holders.
