There is something called MTBF (mean time between failure)... So people can ensure, after measuring the state change of hospital service, just after the Minister of higher official visits... We can ensure/force those higher officials to visit the facilities (it is their job) as inspection.. nothing like it to have a great sense of success.
See what Lalu has done to Railways, just empowering people to do their job, well.
Heard that in China and Russia, ministers visit major hospitals once in 45 days! No wonder they are good in healthcare!
