Examining the impact of psychological distress on short-term postoperative outcomes after elective endovascular aneurysm repair (EVAR).

Abstract

PURPOSE\nPreoperative psychological factors have an impact on postoperative outcomes and there is a paucity of research in vascular surgery. The objective of this study was to examine the impact of preoperative psychological factors on short-term postoperative outcomes in an infrarenal endovascular aneurysm repair (EVAR) cohort.\n\n\nMETHODS\nA prospective, multi-centre observational study was conducted across three vascular units in England. English-speaking participants who were older than 18\xa0years, able to provide informed consent and awaiting an elective standard infrarenal EVAR were eligible for the study. A total of 46 patients undergoing elective infrarenal AAA repair were assessed preoperatively with the State Trait Anxiety Inventory (STAI), Beck s Depression Inventory (BDI-II) and Life Orientation Test-Revised (LOT-R). Data on five short-term postoperative outcomes was collected and analysed using Spearman s rank correlations.\n\n\nRESULTS\nHigher preoperative anxiety levels (ρ\xa0=\xa00.38, p\xa0=\xa00.01), and depression scores (ρ\xa0=\xa00.36, p\xa0=\xa00.02) were moderately correlated with an increased length of postoperative critical care stay. Higher levels of preoperative depression were moderately correlated with greater postoperative opioid analgesia use (ρ\xa0=\xa00.34, p\xa0=\xa00.02). No correlation was witnessed between optimism scores and postoperative outcomes. No correlation was witnessed with respect to total length of stay, number of complications, or time to mobilisation.\n\n\nCONCLUSIONS\nThere is a potential link between preoperative psychological well-being and short-term postoperative outcomes in an EVAR cohort. Further work is necessary to validate this link and examine the role of preoperative interventions in optimising the psychological well-being of patients undergoing EVAR.
