Money is the solution
The NHS is by comparison to other health systems extremely cost effctive. It is far from perfect, it has many inefficiencies, it is resitant to change, it is bureaucratic and it is far too big to manage effectively but for all that it is cheaper than the alternatives. I used to live in america, there is a system that has severe efficiency and cost problems. The equivalent of my GP had a large office with around 10 poeple who simply processed insurance.
The reailty is that any gains to be had from organisation, culture or IT, and I am sceptical that they exist, are dwarved by the constant advances in diagnosis and treatment some of which safe money but overall add to the possible expenditure. In thsi situation yes there needs to be a fous on expenditure but as overall wealth increases the amount spent on health needs to increase and that is the only 'solution'.
