Multimodal prehabilitation to reduce the incidence of delirium and other adverse events in elderly patients undergoing elective major abdominal surgery: An uncontrolled before-and-after study.

ABSTRACT:

Background

Delirium is a common and serious complication in elderly patients undergoing major abdominal surgery, with significant adverse outcomes. Successful strategies or therapies to reduce the incidence of delirium are scarce. The objective of this study was to assess the role of prehabilitation in reducing the incidence of delirium in elderly patients.

Methods

A single-center uncontrolled before-and-after study was conducted, including patients aged 70 years or older who underwent elective abdominal surgery for colorectal carcinoma or an abdominal aortic aneurysm between January 2013 and October 2015 (control group) and between November 2015 and June 2018 (prehabilitation group). The prehabilitation group received interventions to improve patients' physical health, nutritional status, factors of frailty and preoperative anaemia prior to surgery. The primary outcome was incidence of delirium, diagnosed with the DSM-V criteria or the confusion assessment method. Secondary outcomes were additional complications, length of stay, unplanned ICU admission, length of ICU stay, readmission rate, institutionalization, and in-hospital or 30-day mortality.

Result

A total of 360 control patients and 267 prehabilitation patients were included in the final analysis. The mean number of prehabilitation days was 39 days. The prehabilitation group had a higher burden of comorbidities and was more physically and visually impaired at baseline. At adjusted logistic regression analysis, delirium incidence was reduced significantly from 11.7 to 8.2% (OR 0.56; 95% CI 0.32-0.98; P = 0.043). No statistically significant effects were seen on secondary outcomes.

Conclusion

Current prehabilitation program is feasible and safe, and can reduce delirium incidence in elderly patients undergoing elective major abdominal surgery. This program merits further evaluation.

Project description:ObjectivesFor years, many efforts have been invested to prepare patients, in particular, those with reduced physical and psychic status, much better to provide and finally achieve better outocme if there is time available to provide several beneficial measures.MethodsTherefore, the objective was to illustrate the concept and various single elements of a complex prehabilitation concept based on (i) selective references from the medical literature and (ii) own clinical experiences from clinical practice in general and abdominal surgery.ResultsPrehabiliation can be considered the solution of the efforts to improve preoperative status for patients in a disadvantageous status for almost all types of surgery and all other operative and/or interventional procedures. It is the targeted process to improve individual functionality and organ function before a planned (elective) surgical intervention; P. comprises basically nutritional, physical and psychological measures; P. focusses especially onto the elderly, frail and malnourished patients before a planned surgical intervention; the overall aim is to significantly improve final outcome characterized by shorter length of stay, lower complication rate and mortality as well as cost efficiency; P. is especially important in cancer surgery, in which the beneficial effects can be particularly implemented; P. programs and/or "Standard Operating Protocols" (SOP) may help to establish and materialize its single aspects and enhanced recovery after surgery (ERAS). There is still further potential to reliably establish and to utilize the options of prehabilitation measures as listed above.ConclusionsPrehabiliation is an indispensable aspect in today's preparation for elective surgery, which needs to become obligatory part of the preparation measures to planned surgical interventions, which can further contribute to a better final outcome and ERAS as well as, in addtion, needs to be further developed and accomplished.

Project description:BackgroundPostoperative delirium (POD) is common and has negative effects on elderly patients. There is a critical need to identify patients at high risk of POD so that providers can better offer targeted interventions in the preoperative and intraoperative periods. We aimed to characterize the prevalence of preoperative anxiety and investigate whether preoperative anxiety predicted the onset of POD in elderly patients undergoing elective orthopedic surgery.MethodsWe conducted a prospective observational cohort study of elderly patients (aged 65 years or older) undergoing elective orthopedic surgery. Preoperative anxiety was assessed using the Hospital Anxiety and Depression Scale-Anxiety (HADS-A), with clinically significant values defined as HADS-A>7. POD was diagnosed according to the Confusion Assessment Method (CAM) criteria on the 5 postoperative days. To determine the independent risk factors for POD, multivariable logistic regression was conducted, including those variables with a p-value <0.05 at univariate analysis.ResultsThere were 263 patients included in the study. Seventy-three (27.8%) patients were diagnosed to be POD. Median duration of delirium was 2 days. Forty (15.2%) patients were assessed to experience preoperative anxiety. The occurrence of preoperative anxiety in total hip arthroplasty (THA), proximal femoral nail antirotation (PFNA), and total knee arthroplasty (TKA) was 12.5%, 16.1%, and 19.5%, respectively. Based on multivariable analysis, only age (odds ratio [OR]= 1.099, 95% Confidence Interval [CI]: 1.013-1.192; P=0.023), Mini Mental State Examination (MMSE) (OR= 0.603, 95% CI: 0.432-0.842; P=0.003) and preoperative anxiety (OR= 3.119, 95% CI: 1.144-8.500; P=0.026) were independently associated with POD.ConclusionIn conclusion, the current study reveals that preoperative anxiety helps to predict the risk of POD in elderly patients undergoing elective orthopedic surgery. Relieving preoperative anxiety could be a new target for preventive interventions to reduce POD.

Project description:IntroductionThe blood-brain barrier (BBB) disruption contributes to postoperative delirium, but cost-effective and non-invasive assessment of its permeability is not practicable in the clinical settings. Urine albumin to creatinine ratio (UACR), reflecting systemic vascular endothelial dysfunction, may be a prognostic and predictive factor associated with postoperative delirium. The aim was to analyze the relationship between UACR and postoperative delirium in elderly patients undergoing elective non-cardiac surgery.Materials and methodsThrough stratified random sampling, a cohort of 408 individuals aged 60 years and older scheduled for elective non-cardiac surgery were included between February and August 2019 in the single-center, prospective, observational study. The presence of delirium was assessed using the Confusion Assessment Method (CAM) or Confusion Assessment Method for the ICU (CAM-ICU) on the day of surgery, at 2 h after the surgery ending time and on the first 3 consecutive days with repeated twice-daily, with at least 6-h intervals between assessments. Urine samples were collected on one day before surgery, and 1st day and 3rd day after surgery. The primary outcome was the presence of postoperative delirium, and association of the level of UACR with postoperative delirium was evaluated with unadjusted/adjusted analyses and multivariable logistic regression.ResultsPostoperative delirium was observed in 26.75% (107 of 400) of patients within 3 days post-surgery. UACR-Pre (OR, 1.30; 95% CI, 1.14-1.49, p < 0.001), UACR-POD1 (OR, 1.20; 95% CI, 1.13-1.27, p < 0.001), and UACR-POD3 (OR, 1.14; 95% CI, 1.08-1.20, p < 0.001) between the delirium and non-delirium groups show a significant difference, even after adjusting for age, education levels, and other factors.ConclusionAs the marker of endothelial dysfunction, the high perioperative UACR value may be linked to the postoperative delirium in elderly patients undergoing elective non-cardiac surgery.
