OBJECTIVES: Up to date in mainland China, no data has been shown the relationship between health-related quality of life (HRQOL) and health services utilization. This study is aim to confirm the hypothesis that the scale-score of the SF-36 is in linear relationship with Health Services Utilization, and to quantify its linear relationship after the confirmation of above hypothesis. METHODS: Cross-sectional design was conducted. Sample was obtained via three stages of cluster sampling. We use both electronic version (based on QL-Recorder) and paper version of SF-36. Data process was conducted by the structured multiphase regression model. RESULTS: Firstly, in terms of monthly consultation rate, the scale-score of the SF-36 separately intercepted 5.1% contribution. Secondly, with respect to annual consultation rate, the scale-score of the SF-36 solely explained 2.7% contribution. Thirdly, referring to annual hospitalization rate, the scale-score of the SF-36 explained 4.7%. Besides, our research induces that there was gender difference of the scale-score of the SF-36 on Health Service Utilization, namely, the female are higher than the male. CONCLUSION: Our research proved, for the first time in Mainland China, that the hypothesis on linear relation between the scale-score of the SF-36 and Health Service Utility. We further calculated in quantification, the separate contribution rate of the scale-score of the SF-36 to Health Service Utilization.
