The reported experiences of carers in this study highlighted four markers of satisfactory involvement: feeling that information is shared; feeling included in decision making; feeling that there is someone you can contact when you need to; and feeling that the service is responsive to your needs. The majority of carers felt dissatisfied with the level of involvement. The situation we found echoed that found in other studies, i.e. the majority of informal carers (henceforth 'carers') interviewed were dissatisfied with the level of their involvement. However, our investigation, in which the views of health care professionals as well as those of carers were sought, provided invaluable insight into why this might be the case. Two main sources of difficulty were found: hospital systems and processes, and the relationship between nursing staff and carers. The argument made is that practitioners themselves must notice and challenge these barriers if carer involvement is to be facilitated.
