A retrospective analysis of healthcare costs for geriatric patients in intensive care unit following hip fracture surgery

Introduction: The goal of this study was to identify potential predictors of intensive care unit (ICU) expenses in geriatric patients after hip fracture surgery. The research focused to investigate patient-related characteristics and fracture status markers that contribute to increased ICU and overall costs in geriatric hip fracture surgical patients. Materials and Method: A retrospective review of patients who had hip fracture surgery and required intensive care was performed between January 1, 2020 and December 31, 2021. Patient variables were collected via hospital information management system including demographics, co-morbidities, length of stay in ICU and hospital, AO/OTA fracture classification and APACHE score. Hospital Invoice Service provided total and daily intensive care treatment charges and costs. The Spearman correlation coefficient was used to show the relationship between some variables and multiple linear regression analysis was used to evaluate the variables that impact the cost. Results: Intensive care unit expenses constituted 18.92% of the entire cost (1252.46±282.838 TL). APACHE score, Age-adjusted Charlson Comorbidity Index (ACCI), ICU length of stay and hospital length of stay was found statistically significant correlation with ICU expenses (p
