Incidence of Delirium, Risk Factors, and Long-Term Survival of Elderly Patients Hospitalized in a Medical Specialty Teaching Hospital in Mexico City

Background: We determined the incidence, probable risk factors, causes, and long-term survival of delirium in patients hospitalized in a medical specialty teaching hospital in Mexico City. Method: From June to December 1995, 667 elderly patients 60 years and older were hospitalized and assessed within 48 hours, excluding those with delirium at admission, those sedated, on respiratory support, or unable to speak. Results: Twelve percent of the population developed delirium, identified by means of the daily application of the Confusion Assessment Method; its appearance was attributed in 50% to two or more causes, in 10% to an insufficient control of pain, in 7.5% to a preceding surgical event, and in the rest to other causes. Each case was compared randomly with three nonpaired control patients of the same cohort who did not develop delirium. There was a significant increase in the number of cases of delirium in patients older than 75 years (p < .001), those with low schooling (p = .04), those with greater comorbidity (p < .001), those with a hematocrit lower than 30% (relative risk [RR] 2.1, confidence interval [CI] 1.2–4.1), and those with a glucose level greater than 140 mg/dl (RR 2.1, CI 1.2–3.6). Patients with delirium remained hospitalized longer than controls (p = .02). There was no significant difference in the intrahospital mortality of both groups, although during 5 years' follow-up, survivors demonstrated a significant increase in mortality (p = .03) in the group of individuals with delirium during the hospital stay when compared to controls. Conclusion: In this geratric polulation of Mexican patients, delirium incidence was similar to that previously reported in the worldwide literature. Its incidence is associated with longer hospital stay and greater mortality. Age, low level of schooling, greater comorbidity, high glucose levels, poor pain control, and hematocrit lower than 30% were independently associated with a greater incidence of delirium.

Retrospective studies indicate that cancer survival may be affected by the anaesthetic technique. Propofol seems to be a better choice than volatile anaesthetics, such as sevoflurane. The first two retrospective studies suggested better long-term survival with propofol, but not for breast cancer. Subsequent retrospective studies from Asia indicated the same. When data from seven Swedish hospitals were analysed, including 6305 breast cancer patients, different analyses gave different results, from a non-significant difference in survival to a remarkably large difference in favour of propofol, an illustration of the innate weakness in the retrospective design. The largest randomised clinical trial, registered on clinicaltrial.gov, with survival as an outcome is the Cancer and Anesthesia study. Patients are here randomised to propofol or sevoflurane. The inclusion of patients with breast cancer was completed in autumn 2017. Delayed by the pandemic, one-year survival data for the cohort were presented in November 2020. Due to the extremely good short-term survival for breast cancer, one-year survival is of less interest for this disease. As the inclusions took almost five years, there was also a trend to observe. Unsurprisingly, no difference was found in one-year survival between the two groups, and the trend indicated no difference either.

Abstract Background This study describes the long-term survival, risk of reoperation and clinical outcomes of patients undergoing solitary surgical aortic valve replacement (SAVR) with a Carpentier-Edwards Perimount (CE-P) bioprosthetic in Western Denmark. The renewed interest in SAVR is based on the questioning regarding the long-term survival since new aortic replacement technique such as transcatheter aortic-valve replacement (TAVR) probably have shorter durability, why assessment of long-term survival could be a key issue for patients. Methods From November 1999 to November 2013 a cohort of a total of 1604 patients with a median age of 73 years (IQR: 69–78) undergoing solitary SAVR with CE-P in Western Denmark was obtained November 2018 from the Western Danish Heart Registry (WDHR). The primary endpoint was long-term survival from all-cause mortality. Secondary endpoints were survival free from major adverse cardiovascular and cerebral events (MACCE), risk of reoperation, cause of late death, patient-prothesis mismatch, risk of AMI, stroke, pacemaker or ICD implantation and postoperative atrial fibrillation (POAF). Time-to-event analysis was performed with Kaplan-Meier curve, cumulative incidence function was performed with Nelson-Aalen cumulative hazard estimates. Cox regression was applied to detect risk factors for death and reoperation. Results In-hospital mortality was 2.7% and 30-day mortality at 3.4%. The 5-, 10- and 15-year survival from all-cause mortality was 77, 52 and 24%, respectively. Survival without MACCE was 80% after 10 years. Significant risk factors of mortality were small valves, smoking and EuroSCORE II ≥4%. The risk of reoperation was < 5% after 7.5 years and significant risk factors were valve prosthesis-patient mismatch and EuroSCORE II ≥4%. Conclusions Patients undergoing aortic valve replacement with a Carpentier-Edwards Perimount valve shows a very satisfying long-term survival. Future research should aim to investigate biological valves long-term durability for comparison of different SAVR to different TAVR in long perspective.

SummaryData on the long-term survival following venous thromboembolism (VTE) are rare,and the influence of thrombophilia has not been evaluated thus far. Our aim was to assess thrombophilia-parameters as predictors for long-term survival of patients with VTE. Overall, 1,905 outpatients (99 with antithrombin-, protein C or protein S deficiency, 517 with factor V Leiden, 381 with elevated factor VIII and 160 with elevated homocysteine levels, of these 202 had a combination and 961 had none of these risk factors) were included in the study between September 1, 1994 and December 31, 2007. Retrospective survival analysis showed that a total of 78 patients (4.1%) had died during the analysis period, among those four of definite or possible pulmonary embolism and four of bleeding. In multivariable analysis including age and sex an association with increased mortality was found for hyperhomocysteinemia (hazard ratio 2.0 [1.1.-3.5]) whereas this was not the case for all other investigated parameters. We conclude that the classical hereditary thrombophilia risk factors did not have an impact on the long-term survival of patients with a history of VTE. Thus our study supports the current concept that thrombophilia should not be a determinant for decision on long term anticoagulation. However, hyperhomocysteinaemia, known as a risk factor for recurrent VTE and arterial disease, might impact survival.

The Impact

Abstract Aim To investigate whether preoperative malnutrition is associated with long term outcome and survival in patients undergoing radical oesophagectomy for oesophageal or oesophagogastric junction cancer. Background & Methods Dysphagia, weight loss, chemo-radiationtherapy frequently lead to malnutrition in patients with oesophageal or oesophagogastric junction cancer. Severe malnutrition is associated with higher risk of postoperative complications but little is known on the correlation with long term survival. We conducted a single center retrospective study on a prospectively collected database of patients undergoing oesophagectomy from 2008 and 2012 in order to evaluate the impact of preoperative malnutrition with postoperative outcome and long term survival. Preoperative malnutrition was classified as: prealbumin level less than 220 mg/dL (PL), MUST index (Malnutrition Universal Screeening Tool) >2 and weight loss >10%. Results 177 consecutive patients were considered: due to incomplete data 60 were excluded from the analysis that was performed on 117 patients. PL was reported in 52 (44%) patients, MUST index was recorded in 62 (53%), 58 (49%) patients presented more than 10% weight loss at the preoperative evaluation. PL was associated with more postoperative Clavien-Dindo 1-2 complications (p=0.048, OR 2.35 95%IC 1.001-5.50), no differences were observed in mortality, anastomotic leak, major pulmonary complications. MUST index was not correlated with postoperative complications nor mortality but resulted worse in patients treated with chemo-radiotherapy (p=0.046, OR 1.92 95%CI 1.011-3.64). Weight loss >10% was not associated with postoperative complications or mortality. Overall 7 years survival rate was 69%. and DFS was 68%. Malnourished patients did not differ from non-malnourished regarding age, sex, tumor site, tumor stage and histology. No significant difference in 7 years survival rates was observed in patients with PL <220 mg/dL ( 55 % vs 67%), neither in patients with MUST score>2 (58% vs 72%), nor in patients with weight loss >10% (53% vs 70%). Conclusions Malnutrition is more common in patients treated with chemoradiation therapy and it is associated with postoperative complications. However, both long term and disease free survival are not affected by preoperative nutritional status. Larger patient population and data on long term postoperative nutritional status will be analyzed in further studies.

Abstract A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was ‘In [dialysis patients undergoing a valve replacement] is [a bioprosthetic valve superior to a mechanical prosthesis] for [long-term survival and morbidity]’. Altogether more than 501 papers were found using the reported search, of which five represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. There was limited high-quality evidence with all studies being retrospective. One meta-analysis and four cohort studies provided the evidence that there was no significant difference in long-term survival based on prosthesis type. However, the majority of studies demonstrated a significantly higher rate of valve-related complications including bleeding and thromboembolism, and readmission to hospital in the mechanical valve prosthesis group, likely related to the requirement for long-term anticoagulation. We conclude that overall long-term survival in dialysis-dependent patients is poor. While prosthesis type does not play a significant contributing role to long-term survival, bioprosthetic valves were associated with significantly fewer valve-related complications. Based on the available evidence, a bioprosthetic valve may be more suitable in this high-risk group of patients as it may avoid the complications associated with long-term anticoagulation without any reduction in long-term survival.
