Longitudinal analysis of technical efficiency of the model of male circumcision in different kinds of people / 重庆医学

ABSTRACT

Objective To longitudinally analyze the unit costs and technical efficiency of the model of male circumcision in the different kinds of persons .Methods Unit costs were calculated by the person and period using longitudinal data from 3 kinds of persons ,and then technical efficiency and Malmquist indices were measured with an approach to data envelopment analysis . Results Theunit costs for changing the willingness to accept surgery changed dramatically ,decreasing from 7 166 .67 yuan(mean) to 737 .31 yuan ,while the costs for changing the ratio of the surgery increased from 666 .64 yuan (mean) to 744 .58 yuan ,and its technical efficiency was averaging between 0 .95-0 .96 .Conclusion The time series of unit costs for changing the willingness to ac-cept surgery dramatically dropped ,while changing the ratio of the surgery formed a U-shape curve with an inflection point before which unit costs dramatically dropped and another inflection point beyond which unit costs went up .These findings can inform pro-gram managers of the changing unit costs when extending or expanding the program .
