Chinese Journal of Hospital Administration 1996;0(03):-
A summary is made on a11 the experiences from five attached general hospitals which carried out Shanghai new policy of Work rescheduling and organization restracturing.The external pressure and internal motive of the change from"compulsory rescheduling"to"voluntary rescheduling" are analyzed.A search for the distribution of the points for attack on the problem of hospital control of medical cost is made.A comparative study is conducted on the relationship between time and the inten- sity of the control,the inner relationship between the independent variables and the intensity of control. The conclusion shows the change of the hospital's control role to the voluntary one has something to do with the equalibrium of relative forces.The point for breakthrough lies at the control of drugs.A search for the points for attack on the problem of hospital control of medical cost is not only necessary for arresting the rocketing of medical cost,but also helpful for capturing the confidence of the concerned and strengthening hospital management,thus laying a good foundation for a stable transition to a new healthcare insurance program.

A typical investigation on third-tier general hospitals, third-tier specialty hospitals, second-tier district or county central hospitals, urban community hospitals, and rural township health centers in Shanghai was conducted so as to examine the responsiveness of outpatients and inpatients to the health system. Most of the patients surveyed said that they could get prompt attention and that they had convenient access to medical information from the community or the mass media. More than half of the inpatients and outpatients thought that they had autonomy with regard to treatment and a greater number of patients made their own choices of doctors and nurses. Most of the patients were willing to talk freely with their doctors about their confidential medical history and could get rational explanations about their conditions from the doctors. The results indicate that reform of the health system in Shanghai has attached importance to the responsiveness of patients and that good effects have been achieved.
