Results: Univariate analysis found that the highest LOS was in the less than ideal category (<6 days), the highest age characteristics were in young people and adults (15-49 years), the highest gender was male, the highest payment method was in the government insurance category, the highest exit method was in the homecoming category, the highest occupation was in the unemployed/not yet employed category. The results of the bivariate analysis of the chi-square test showed the characteristics of age (p = 0.012), gender (p = 0.473), payment method (p = 0.485), exit method (p = 0.570), and occupation (p = 0.021). Conclusion: There is a relationship between age and occupation characteristics with LOS, and there is no relationship between gender characteristics, payment method and exit method with LOS.
