Influencing Factors of Hospital Costs for Pituitary Tumor Under DRG Payment

  Objective  To analyze the influencing factors of hospitalization expenses of patients treated in the KC19 group by the neurosurgery department of a tertiary hospital in Beijing, and provide reference for the refinement of diagnosis related groups(DRG).

  Methods  The medical records of 3809 patients from January 1, 2017 to November 30, 2021 were reviewed, and relevant influencing factors were determined using descriptive statistics, univariate analysis, and multivariate linear regression.

  Results  Among the 3809 patients included in this study, the average total hospitalization cost was 36 166.82 yuan, and the average hospital stay was 9.42 days. Neuroendoscopy accounted for 35.2%, while major complications or comorbidities (MCC) and complications or comorbidity (CC) accounted for 40%. Univariate analysis found that hospitalization costs were associated with gender, length of hospital stay, number of other diagnoses, number of surgical procedures, use of neuroendoscopy, and the presence of MCC or CC. Multivariate analysis found that the main influencing factors were the length of hospital stay, followed by the number of other diagnoses, the number of surgical operations, whether neuroendoscopy was used, whether there was MCC or CC, and gender.

  Conclusion  In the follow-up fine grouping of KC19, the above influencing factors should be considered, and the use of neuroendoscopy and the presence of MCC or CC should be included in the grouping criteria.
