Does admission to intensive care post total joint arthroplasty result in poorer outcomes 12-months after surgery?

BackgroundIt is unknown if total joint arthroplasty (TJA) patients admitted to the intensive care unit (ICU) benefit from the surgery. This impedes clinical decision-making, resource allocation and patient informed consent. This study aims to identify whether admission to ICU post-TJA surgery is associated with poorer quality of life, pain and function, compared to those not requiring ICU admission.MethodsData on patients who underwent elective total hip or knee arthroplasty between 2006 and 2019 were extracted from a single-institution registry in Melbourne, Australia. Adjusted mixed-linear regression models were used to estimate the mean difference at 12 months in quality of life (VR-12), and pain and function (WOMAC) between patients admitted postoperatively to ICU and those not admitted.ResultsOf the 8444 patients that met the study inclusion criteria, 128 (1.5%) patients were admitted to ICU peri- or postoperatively. The median length of stay in ICU was 1 day (IQR = 1). Patients in both groups reported similar clinically meaningful improvements in quality of life, pain and function 12-months after surgery.ConclusionClinicians weighing up risks versus benefits of TJA in patients with a higher risk of ICU admission should not overlook the significant improvements in quality of life, pain and function likely to be seen.
