Abstract
This retrospective study investigated the relationship between preoperative comorbidities and hospitalization duration in patients undergoing total hip arthroplasty. Conducted at a single tertiary center, the analysis included 85 patients, who were stratified based on length of hospital stay into two groups: short stay (≤10 days) and prolonged stay (>10 days). Comorbidities were recorded as binary variables, and statistical tests, including Chi-square analysis, were applied to identify associations with hospitalization length. The most prevalent condition was arterial hypertension, followed by congestive heart failure, hepatic steatosis, and atrial fibrillation. Significant associations were found between prolonged hospitalization and specific comorbidities, notably congestive heart failure, liver cirrhosis, mitral regurgitation, pleural effusion, and arterial hypertension. In contrast, other conditions such as diabetes mellitus and depression did not significantly affect length of stay. These findings emphasize the role of cardiovascular and hepatic comorbidities as key predictors of delayed recovery and support the integration of individualized risk assessment into perioperative planning to improve clinical outcomes and optimize resource utilization.
