The effect of case mix index on the science and technology evaluation metrics of disciplines in tertiary public general hospital / 中华医学科研管理杂志

ABSTRACT

Objective:Case mix index indicates the capacity of disease diagnosis and treatment, as well as the quality of health cares in related disciplines. Science and technology evaluation metrics represent the level of innovation and sustainable development of science and technology. Quality of health care and sustainable development are considered as two key evaluation indicators in the performance evaluation of national tertiary public hospitals. This study aimed to explore the effect of case mix index on the science and technology evaluation metrics.Methods:According to a cross-sectional design, the relationship between case mix index and science and technology evaluation metrics was analyzed in a tertiary public general hospital between 2017 and 2019.Results:In three years′ period time, the departments in top 100 disciplines of science and technology evaluation metrics had the case mix index 17% which was higher than other departments in non-top 100 disciplines ( P<0.05). In the multivariate analysis, higher case mix index increased a 2.29-fold higher probability to be in top 100 disciplines. They are under the receiver operative character curve between case mix index and top 100 disciplines in evaluation of departments was 0.716 ( P=0.001). Conclusions:Case mix index indicated the level of science and technology evaluation metrics and the clinical departments should improve the case mix index, service quality of health care and the motivation of sustainable development.
