A randomized controlled trial of home telecare

We have established a randomized controlled trial of home telecare. The intervention aims to address a growing problem in the National Health Service (NHS), that is, high admission rates of patients with exacerbations of chronic obstructive pulmonary disease (COPD). Equipment procurement for the trial has been difficult, as no single supplier was able to meet the project s full requirements. The fact that the service is provided by existing clinical NHS staff has advantages when considering the generalizability of the results within the NHS. However, there are also disadvantages, since existing staff have little research experience. Considerable time has been required to help staff familiarize themselves with the equipment and become comfortable with its use. This has posed a barrier to the implementation of the service.
