Abstract:Objective To analyze the influencing factors of hospitalization costs for cesarean scar pregnancy and provide a basis for reasonable cost control in clinical practice.Methods A study was conducted on patients with cesarean scar pregnancy who were discharged from a hospital in Shandong Province from January 2019 to July 2022. Statistical methods such as descriptive analysis, Chi-square test, Fisher's exact probability method, rank sum test, and multiple linear regression analysis were used for the study.Results Finally 327 patients with CSP were enrolled in the study. The total hospitalization expenses showed a fluctuating downward trend, with a median of 4 364.65 yuan and an average annual growth rate of 3.04%. The drug cost showed a continuous upward trend, with an average annual growth rate of 9.96%. There were statistically significant differences in hospitalization expenses among hospital stay, gestational age, comorbidities, anesthesia methods, and surgical types (P<0.05). Multiple linear regression analysis showed that the main influencing factors of hospitalization expenses were anesthesia method, surgical type, length of hospital stay, and gestational age (P<0.05).Conclusion It is clinically necessary to further reduce hospitalization costs for CSP patients by early diagnosis and treatment, reasonable selection of surgical types and anesthesia methods, and scientific reduction of hospital stay.
