Background: The aim was to investigate the total prevalence of known and undiagnosed diabetes mellitus (DM), and the association of DM with perioperative complications following elective, infrarenal, open surgical (OSR) or endovascular (EVAR), Abdominal Aortic Aneurysm (AAA) repair., Methods: In this Norwegian prospective multicentre study, 877 patients underwent preoperative screening for DM by HbA 1c measurements from November 2017 to December 2020. Diabetes was defined as screening detected HbA 1c  ≥ 48 mmol/mol (6.5%) or previously diagnosed diabetes. The association of DM with in-hospital complications, length of stay, and 30-day mortality rate were evaluated using adjusted and unadjusted logistic regression models., Results: The total prevalence of DM was 15% (95% CI 13%,17%), of which 25% of the DM cases (95% CI 18%,33%) were undiagnosed upon admission for AAA surgery. The OSR to EVAR ratio was 52% versus 48%, with similar distribution among DM patients, and no differences in the prevalence of known and undiagnosed DM in the EVAR versus the OSR group. Total 30-day mortality rate was 0.6% (5/877). Sixty-six organ-related complications occurred in 58 (7%) of the patients. DM was not statistically significantly associated with a higher risk of in-hospital organ-related complications (OR 1.23, 95% CI 0.57,2.39, p = 0.57), procedure-related complications (OR 1.48, 95% CI 0.79,2.63, p = 0.20), 30-day mortality (p = 0.09) or length of stay (HR 1.06, 95% CI 0.88,1.28, p = 0.54). According to post-hoc-analyses, organ-related complications were more frequent in patients with newly diagnosed DM (n = 32) than in non-DM patients (OR 4.92; 95% CI 1.53,14.3, p = 0.005)., Conclusion: Twenty-five percent of all DM cases were undiagnosed at the time of AAA surgery. Based on post-hoc analyses, undiagnosed DM seems to be associated with an increased risk of organ related complications following AAA surgery. This study suggests universal DM screening in AAA patients to reduce the number of DM patients being undiagnosed and to improve proactive diabetes care in this population. The results from post-hoc analyses should be confirmed in future studies., (© 2024. The Author(s).)

Emergency laparotomy (EL) is a high-risk procedure. However, available evidence regarding outcome after emergency surgery in very old patients is limited. The aim of this observational study was to investigate outcome following EL in patients ≥80 years of age., Methods: This single-center retrospective study was undertaken at Haukeland University Hospital, Norway. Demographic data, pre-operative risk assessment, surgical procedures, intrahospital logistics, complications, mortality, and discharge data were collected from the medical records. Primary outcome was 30-day mortality. Secondary outcomes were 90-day mortality, 1-year mortality, post-operative complications, and level of care at discharge., Results: One hundred and six patients aged 80-96 years underwent EL between 2015 and 2016. Of these, 58% had cardiopulmonary disease, and 16% lived in a nursing home before surgery. Resection of colon was performed in 26 cases, adhesiolysis was performed in 24, and resection of small intestine in 18. Within 30 days, 28 patients died (26%), 15 during the first post-operative week. For 82% of the patients, at least one complication occurred, and medical complications were far more frequent than surgical. Post-operatively, pulmonary morbidity was found in 51 patients (48%) and delirium in 42 (40%). The number of intrahospital deaths was 25 (24%). Among the 81survivors, 53 were discharged to a nursing home (65%). One-year mortality was 47% (50/106)., Conclusions: Mortality after EL in octo- and nonagenarians is very high. Medical complications are more common than surgical, and functional decline is frequent. Future studies should focus on the effect of a care bundle including geriatric intervention in these patients., (© 2020 The Authors.

Aims: Established surgical scores have limitations in delineating risk among candidates for transcatheter aortic valve implantation (TAVI). Assessment of frailty might help to estimate the mortality risk and identify patients likely to benefit from treatment. The aim of the study was to develop a frailty score to guide the decision for TAVI., Methods and Results: We conducted a prospective observational study in patients ≥70 years referred for TAVI during 2011-15. A Heart Team had declined the patients for open heart surgery due to high risk but accepted them for TAVI. Prior to the procedure, a geriatric assessment (GA) was performed. Based on this, an 8-element frailty score with a 0-9 (least frail-most frail) scale was developed. A total of 142 patients, 54% women, mean age 83 (standard deviation 4) years, with severe and symptomatic aortic stenosis were assessed. All-cause 2 year mortality was 11%. The novel GA frailty score predicted 2-year mortality in Cox analyses, also when adjusted for age, gender, and logistic EuroSCORE [hazard ratio (HR) 1.75, 95% confidence interval (CI): 1.28-2.42, P < 0.001]. A receiver operating characteristic (ROC) curve analysis indicated that a GA frailty score cut-off at ≥4 predicted 2-year mortality with a specificity of 80% (95% CI: 73-86%) and a sensitivity of 60% (95% CI: 36-80%). The area under the curve was 0.81 (95% CI 0.71-0.90)., Conclusion: A novel 8-element GA frailty score identified gradations in survival in patients declined for open heart surgery. Patients with higher GA frailty scores had significantly higher 2-year mortality after TAVI., (© The Author(s) 2018.

Background: Octogenarians with aortic stenosis are an increasing population of patients admitted for surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI). Although adequate sleep is important after illness and surgery, it has scarcely been studied in the immediate postoperative phase., Aims: To determine and compare the nature of self-reported sleep and insomnia, and recorded sleep-wake patterns in octogenarians during the in-hospital postoperative phase after SAVR or TAVI., Methods: A prospective cohort design was used that included octogenarian patients undergoing SAVR or TAVI at a regional university hospital. Self-reports were used to document sleep and insomnia, and actigraphy was used to record sleep-wake patterns. Data were collected at baseline preoperatively, and then daily for the first five postoperative days., Results: SAVR patients experienced the most insomnia on postoperative nights later in recovery, while TAVI patients experienced the most insomnia on postoperative nights early in recovery. The median total sleep time, as measured by actigraphy, was 6.4 h, and the median sleep efficiency was 79% for the five postoperative nights, but no differences were found between SAVR and TAVI patients on this parameter. All patients slept more during daytime than at night, with SAVR patients having significantly more total sleep hours for all five days than TAVI patients (p < 0.01)., Conclusion: Octogenarians with aortic stenosis had disturbed self-reported sleep, increased insomnia, and disturbed sleep-wake patterns postoperatively, resulting in more daytime sleep and inactivity. In patients undergoing SAVR or TAVI, sleep evolves differently during the in-hospital postoperative phase., (© The European Society of Cardiology 2015.)

Postoperative delirium (PD) after transcatheter aortic valve implantation (TAVI) remains to be explored. We sought to (1) determine the incidence of PD in octogenarians who underwent TAVI or surgical aortic valve replacement (SAVR), (2) identify its risk factors, and (3) describe possible differences in the onset and course of PD between treatment groups. A prospective cohort study of consecutive patients aged ≥80 years with severe aortic stenosis who underwent elective TAVI or SAVR (N = 143) was conducted. The incidence of PD was assessed for 5 days using the Confusion Assessment Method (CAM). Risk factors for PD were studied with logistic regression. Patients treated with TAVI were older (p ≤0.001), had lower cognitive scores (p = 0.007), and more co-morbidities (p = 0.003). Despite this, significantly fewer (p = 0.013) patients treated with TAVI (44%) experienced PD compared to patients treated with SAVR (66%). Undergoing SAVR (p = 0.02) and having lower cognitive function (p = 0.03) emerged as risk factors for PD, whereas gender, activities of daily living, frailty, atrial fibrillation, and postoperative use of opioids and anxiolytics did not. Patients treated with TAVI and without PD during the first 2 postoperative days were unlikely to experience PD on subsequent days. The onset of PD after SAVR could occur at any time during the postoperative evaluation. In conclusion, SAVR in octogenarian patients with aortic stenosis might be considered as a predisposing factor for PD. Our data also suggest that the onset of PD was more unpredictable after SAVR., (Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.)
