Abstract：Objective A generalized grey correlation analysis was used to analyze the factors affecting the hospitalization cost of simple goiter. Methods By using comprehensive correlation degree and correlation sequence to study the factors affecting the hospitalization expenses of discharged patients who with single pure goiter in a third nail hospital from 2013 to 2017.Results The comprehensive correlation degree of influencing factors of hospitalization cost of simple goiter from high to low is: consumables (0.872), diagnostics (0.849), comprehensive medical services (0.794), treatment (0.721), western medicine (0.624) and other categories (0.597), relational sequence according to the correlation degree from high to low order, consumable expenses have the greatest impact on hospitalization expenses. In the comprehensive correlation sequence of factors affecting the hospitalization cost of surgical patients, the treatment category occupies the first place, which reflects the technical value of physicians.Conclusion Through generalized correlation analysis, the influencing factors and trends of hospitalization costs can be accurately determined, and data support is provided for the future control fee and research compensation mechanism.
