Abstract
This paper analyzes lengths of stay at the hospital using data from patients hospitalized for cataract ((IR-DRG (International Redefined Diagnosis Related Groups) 2041) in Japan. Unlike other countries, not only one-eye surgeries but also two-eye surgeries are done in a single period of hospitalization in Japan. It is an interesting question whether two-eye surgeries reduce the length of stay at the hospital or not. In this paper, the lengths of stay of one-eye and two-eye surgeries were analyzed by the discrete type proportional hazard model. The factors which might affect the decision to perform one-eye or two-eye surgeries were also analyzed by the discriminant and tobit analyses.<br>In one-eye surgeries, we found that child, place to return after hospitalization and types of additional operations were important factors making the length of stay longer. In two-eye surgeries, place to return after hospitalization and types of additional operations were found to be important factors making the length of stay longer. The lengths of stay for two-eye surgeries were shorter than doubles of those for one-eye surgeries except one hospital. The patients who had two-eye surgeries were found to be older with lower tendency of going to other facilities after hospitalization than those who had one-eye surgeries. We also found that as hospitals became larger and more profitable, the proportion of two-eye surgeries became larger.
