Preoperative transthoracic echocardiograms (TTE) before hip fracture repairs are controversial. This study aimed to quantify the frequency of ordering TTE, the appropriateness of testing based on current guidelines, and the impact of TTE on in-hospital morbidity and mortality outcomes.
This retrospective chart review of adult patients admitted with hip fracture compared the length of stay (LOS), time to surgery, in-hospital mortality, and postoperative complications between TTE and non-TTE groups. TTE patients were risk stratified using the Revised Cardiac Risk Index (RCRI) to compare TTE indication according to current guidelines.
Of the 490 patients included in this study, 15% received preoperative TTE. The median LOS of the TTE and non-TTE groups was 7.0 and 5.0 d, respectively, whereas the median time to surgery was 34 and 14 h, respectively. The odds of in-hospital mortality remained significantly higher in the TTE group after adjusting for RCRI but not when adjusted for the Charlson Comorbidity Index. Significantly more patients in the TTE groups had postoperative heart failure and up triage in the intensive care unit. Furthermore, 48% of patients with an RCRI score of 0 received preoperative TTE, with cardiac history as the most typical indication. TTE changed perioperative management in 9% of patients.
Patients subjected to TTE before hip fracture surgery had a longer LOS and time to surgery, with higher mortality and intensive care unit up triage rates. TTE evaluations were typically conducted for inappropriate indications, which rarely made meaningful changes to patient management.
髋部骨折修复术前进行经胸超声心动图(TTE)存在争议。本研究旨在量化 TTE 的检查频率、基于现行指南的检查适宜性以及 TTE 对住院期间发病率和死亡率的影响。
本回顾性图表分析纳入了因髋部骨折入院的成年患者,比较了 TTE 组和非 TTE 组的住院时间(LOS)、手术时间、住院期间死亡率和术后并发症。使用修订后的心脏风险指数(RCRI)对 TTE 患者进行风险分层,以比较根据现行指南的 TTE 指征。
本研究共纳入 490 例患者,其中 15%接受了术前 TTE。TTE 组和非 TTE 组的 LOS 中位数分别为 7.0 和 5.0 天,手术时间中位数分别为 34 和 14 小时。校正 RCRI 后,TTE 组的住院期间死亡率仍显著较高,但校正 Charlson 合并症指数后则无显著差异。TTE 组术后心力衰竭和 ICU 上调的患者明显更多。此外,48% RCRI 评分为 0 的患者接受了术前 TTE,心脏病史是最常见的指征。TTE 改变了 9%患者的围手术期管理。
髋部骨折手术前进行 TTE 的患者 LOS 和手术时间更长,死亡率和 ICU 上调率更高。TTE 评估通常针对不适当的指征进行,很少对患者管理产生有意义的改变。
