‘ 7 Day NHS’ is it required and financially feasible for NHS

For my MBA in Healthcare the dissertation topic is to assess and evaluate the viability and suitability of ‘7 Day NHS’. The government has promised to make NHS a fully functional 7-day service. 

This would be very expensive, stretched workforce as there are not enough GPs/ hospital doctors to provide such a service for 7 days.

As part of my dissertation I would like to evaluate the research into the actual benefit of having a fully functional 7-day health service, if at its being done in other countries. Its actual benefits- as the cost cutting from essential services to provide a 7 days service ma may compromise of quality of acre and will it actually benefit people’s health. Which is doubtful

At present NHs is actually working 7 days for Emergency services and making other non-urgent departments open 7 days will not be of any actual benefit to people. Example a Skin / dermatology department working for 7 days will not make any huge difference to the well-being of patients than a fully functional Emergency department which would actually save lives.
