Could TripAdvisor-style reviews work for social care providers?

In the recent White Paper Caring for our Future, the government announced its intention to support comparison websites which assist users in choosing providers in England. With the popularity of websites such as TripAdvisor, it seems like an obvious solution to solving the problems of limited information in the social care sector. This has already been applied with some success in health care with NHS Choices and other independent websites. However, a new PSSRU discussion paper Using Online Reviews in Social Care explores the potential challenges involved in setting up this type of website for provider quality in the social care sector.
