Abstract
|
|
|
Background: The purpose of this study was to compare and analyze the differences in charges and length of stay per case between spinespecialty hospitals and non-specialty hospitals, and to identify the factors that influenced them.
Methods: This study used claims data from the Health Insurance Review and Assessment Service, including inpatient visits from January 2021to December 2022. The healthcare facility status data was used to identify the characteristics of study hospitals. Multilevel analysis was conductedto identify factors associated with the charges and Poisson regression analysis was conducted to analyze the length of stay between spinespecialty hospitals and non-specialty hospitals. There were 32,015 cases of spine specialty hospitals and 17,555 cases of non-specialty hospitals.
Results: For four of five common spinal surgeries, specialty hospitals shaped longer length of stay than those of non-specialty hospitals.
Multilevel and Poisson regression analysis revealed that regardless of the type of surgery, higher age and higher Charlson comorbidity indexscores were significantly associated with an increase in both the charges per case and length of stay (p<0.05). However, when hospitals werelocated in metropolitan areas, there was a significant decrease (p<0.05).
Conclusion: This study found that specialty hospital had higher inpatient charges and loner length of stay contrary to the previous studyresults. Further studies will be needed to find which contribute to the differences.
