At NHS Berkshire West we have developed a directory of Intermediate Care services for GPs. The aim is that busy GPs can keep up to date with the large menu of services available under the umbrella of Intermediate Care which aims to prevent people from going into hospital. The app supports touch screen dialling so GPs do not have to carry service information with them.
It was developed as a web page so that it is compatible with the majority of smart phones. It was cheap to develop and easy to install by simply accessing a weblink from the phone.
