"This man needs to be adequately informed so that he fully understands on how he can take part in protecting his family, some men lack knowledge on the issues ……they may not have enough opportunity to learn more on these issues".

Greaves also said that the ratings also provide patients with easier to understand information on how to select a hospital.
