Purpose: The purpose of this study was to evaluate preoperative transthoracic echocardiography (TTE) on cardiac intervention, length of stay (LOS), inpatient mortality, and costs.
Methods: A retrospective series of 43 preoperative TTE and 161 non-TTE (control) hip fracture patients (> 65 years) was reviewed. The data collected included ASA score, comorbidities, indication for TTE, perioperative cardiac intervention, LOS, inpatient mortality, and cost.
Results: One of 43 (2.4%) (TTE) had a cardiac intervention (PTCA/CABG). Zero interventions occurred in the control group. The average time to operation was 1.5 days (TTE) and 0.93 days (control) (p < 0.001). The average LOS was 7.2 days (TTE) and 6.0 days (control), (p = 0.04). Patients (American Society of Anesthesiologists Physical Status Classification 3 and 4 patients), LOS was 7.3 days (TTE) and 6.3 days (control) (p = 0.18). Inpatient mortality was 2.3% (TTE) and 3% (control) (p = 0.493). There was no correlation between TTE and anesthesia. Hospital costs were different between groups (TTE $24,445 and control $18,429, p = 0.02).
Conclusions: Preoperative TTE in elderly patients with hip fractures resulted in a low cardiac intervention rate. Patients undergoing preoperative TTE prior to surgery had longer times to operation, LOS, and higher hospital costs. The utility of TTE as a preoperative screening tool is limited in the geriatric hip fracture population and does not appear to effect perioperative mortality rates.
