Analysis on the Composition of Hospitalization Expenses of Patients with Maxillofacial Deformities Based on Grey Correlation and Structural Variation Analysis
Objectives To analyze the composition and influencing factors of hospitalization expenses for patients with maxillofacial deformities,in order to provide evidence for effectively controlling the hospitalization expenses of patients and reducing the economic burden of diseases.Methods The details of hospitalization expenses of 533 patients with maxillofacial deformities in a Three A and Tertiary Stomatology Hospital in Chongqing from January 1st,2014 to December 31st,2021 were collected,and the correlation,structural variability and contribution rate of each patient's inpatient costs were analyzed using the gray correlation and structural variation analysis.Results The average annual growth rate of hospitalization expenses from 2014 to 2021 was 3.35%,with the nursing expenses having the highest annual growth rate of 10.82%.The quartile of the average hospitalization expense of per patient was 68875.6(53757.16,78567.39)yuan,with the highest proportion being the surgical treatment expense,accounting for 56.41%.The grey correlation analysis showed that the highest correlation coefficient was the surgical treatment expense(0.8964).The results of the structural change analysis showed that the structure with the greatest variability was the surgical treatment expense(0.1592),and it showed an upward trend;the highest structure contribution rate was from the surgical treatment expenses(47.22%)and consumables expenses(41.26%),with the contribution rates of medical service expense,treatment operation expense,nursing expense,diagnostic project expense,and non-surgical treatment expense being relatively small,totaling 5.9%.Conclusions The surgical treatment fee and consumables expense were the most influential factors of patients'average hospitalization expense,but there was currently an issue of overly high proportion of consumables expense and excessively low technical labor project expenses.It was suggested to appropriately reduce the consumables expense and reasonably increase the proportion of technical labor project expenses.
