Risk factors and outcomes for postoperative delirium after major surgery in elderly patients
Background: Early identification of patients at risk for delirium is important, since adequate well timed interventions could prevent occurrence of delirium and related detrimental outcomes. The aim of this study is to evaluate prognostic factors for delirium, including factors describing frailty, in elderly patients undergoing major surgery. Methods: We included patients of 65 years and older, who underwent elective surgery from March 2013 to November 2014. Patients had surgery for Abdominal Aortic Aneurysm (AAA) or colorectal cancer. Delirium was scored prospectively using the Delirium Observation Screening Scale. Pre- and peri-operative predictors of delirium were analyzed using regression analysis. Outcomes after delirium included adverse events, length of hospital stay, discharge destination and mortality. Results: We included 232 patients. 51 (22%) underwent surgery for AAA and 181 (78%) for colorectal cancer. Postoperative delirium occurred in 35 patients (15%). Predictors of postoperative delirium included: delirium in medical history (Odds Ratio 12 [95% Confidence Interval 2.7-50]), advancing age (Odds Ratio 2.0 [95% Confidence Interval 1.1-3.8]) per 10 years, and ASA-score ≥3 (Odds Ratio 2.6 [95% Confidence Interval 1.1-5.9]). Occurrence of delirium was related to an increase in adverse events, length of hospital stay and mortality. Conclusion: Postoperative delirium is a frequent complication after major surgery in elderly patients and is related to an increase in adverse events, length of hospital stay, and mortality. A delirium in the medical history, advanced age, and ASA
Dementia and delirium, the outcomes in elderly hip fracture patients
Background: Delirium in hip fractured patients is a frequent complication. Dementia is an important risk factor for delirium and is common in frail elderly. This study aimed to extend the previous knowledge on risk factors for delirium and the consequences. Special attention was given to patients with dementia and delirium. Methods: This is a retrospective cohort study performed in the Amphia Hospital, Breda, the Netherlands. A full electronic patient file system (Hyperspace Version IU4: Epic, Inc., Verona, WI, USA) was used to assess data between January 2014 and September 2015. All patients presented were aged ≥70 years with a hip fracture, who underwent surgery with osteosynthesis or arthroplasty. Patients were excluded in case of a pathological or a periprosthetic hip fracture, multiple traumatic injuries, and high-energy trauma. Patient and surgical characteristics were documented. Postoperative outcomes were noted. Delirium was screened using Delirium Observation Screening Scale and dementia was assessed from medical notes. Results: Of a total of 566 included patients, 75% were females. The median age was 84 years (interquartile range: 9). Delirium was observed in 35%. Significant risk factors for delirium were a high American Society of Anesthesiology score, delirium in medical history, functional dependency, preoperative institutionalization, low hemoglobin level, and high amount of blood transfusion. Delirium was correlated with a longer hospital stay (P=0.001), increased association with comp
Mortality after major amputation in elderly patients with critical limb ischemia
Background: Owing to the aging population, the number of elderly patients with critical limb ischemia (CLI) has increased. The consequence of amputation is immense. However, at the moment, information about the mortality after amputation in the elderly vascular patients is unknown. For this reason, this study evaluated mortality rates and patient-related factors associated with mortality after a major amputation in elderly patients with CLI.
Methods: From 2006 to 2013, we included patients aged >70 years who were treated for chronic CLI by primary or secondary major amputation within or after 3 months of initial therapy (revascularization or conservative management). Outcome measurements were mortality after major amputation and factors associated with mortality (age, comorbidity and timing of amputation).
Results: In total, 168/651 patients (178 legs; 26%) underwent a major amputation. Patients were stratified by age: 70–80 years (n=86) and > 80 years (n=82). Overall mortality after major amputation was 44%, 66% and 85% after 1, 3 and 5 years, respectively. The 6-month and 1-year mortality in patients aged 80 years or older was, respectively, 59% or 63% after a secondary amputation 3 months. Per year of age, the mortality rate increased by 4% (P=0.005). No significant difference in mortality after major amputation was found in the presence of comorbidity or according to Rutherford classification.
Conclusion: Despite developments in the treatment of CLI by revascularization, amputation rates remain high and are associated with tremendous mortality rates. Secondary amputation after a failed attempt of revascularization causes a higher mortality. Further research concerning timing of amputation and patient-related outcome is needed to evaluate if selected patients might benefit from primary amputation
Long-term outcome of ruptured abdominal aortic aneurysm: Impact of treatment and age
Background: Despite advances in operative repair, ruptured abdominal aortic aneurysm (rAAA) remains associated with high mortality and morbidity rates, especially in elderly patients. The purpose of this study was to evaluate the outcomes of emergency endovascular aneurysm repair (eEVAR), conventional open repair (OPEN), and conservative treatment in elderly patients with rAAA.Methods: We conducted a retrospective study of all rAAA patients treated with OPEN or eEVAR between January 2005 and December 2011 in the vascular surgery departmen
Low skeletal muscle mass as a risk factor for postoperative delirium in elderly patients undergoing colorectal cancer surgery
Background: Both low skeletal muscle mass (LSMM) and delirium are frequently seen in elderly patients. This study aimed to investigate the association between preoperative LSMM and postoperative delirium (POD) in elderly patients undergoing colorectal cancer (CRC) surgery and to design a model to predict POD. Patients and methods: This is a retrospective observational cohort study. Patients aged 70 years or older undergoing CRC surgery from January 2013 to October 2015 were included in this study. The cross-sectional skeletal muscle area at the level of the third lumbar vertebra using computed tomography was adjusted for patients' height, resulting in the skeletal muscle index. The lowest quartile per sex was defined as LSMM. Short Nutritional Assessment Questionnaire for Residential Care and KATZ-Activities of Daily Living were used to define malnourishment and physical dependency, respectively. POD was diagnosed using the Delirium Observational Screening Scale and geriatricians' notes. Results: Median age of the 251 included patients was 76 years (IQR, 73-80 years), of whom 56% of patients were males, 24% malnourished, and 15% physically impaired. LSMM and POD were diagnosed in 65 and 33 (13%) patients, respectively. POD occurred significantly more in patients with LSMM (25%) compared with patients without LSMM (10%), P=0.006. In the multivariate analysis, age, history of delirium, and LSMM were significantly associated with POD. In addition, this effect increased in patients with LSMM and malnourishment (P=0.019) or physical dependency (P=0.017). Conclusion: Age, history of delirium, LSMM, and malnourishment or physical dependency were independen

Protocol for a prospective, longitudinal cohort study on the effect of arterial disease level on the outcomes of supervised exercise in intermittent claudication: the ELECT Registry
Introduction Despite guideline recommendations
advocating conservative management before
invasive treatment in intermittent claudication, early
revascularisation remains widespread in patients with
favourable anatomy. The aim of the Effect of Disease
Level on Outcomes of Supervised Exercise in Intermittent
Claudication Registry is to determine the effect of the
location of stenosis on the outcomes of supervised
exercise in patients with intermittent claudication due to
peripheral arterial disease.
Methods and analysis This multicentre prospective
cohort study aims to enrol 320 patients in 10 vascular
centres across the Netherlands. All patients diagnosed
with intermittent claudication (peripheral arterial disease:
Fontaine II/Rutherford 1–3), who are considered candidates
for supervised exercise therapy by their own physicians
are appropriate to participate. Participants will receive
standard care, meaning supervised exercise therapy first,
with endovascular or open revascularisation in case of
insufficient effect (at the discretion of patient a
Impact of the European Working Time Directive (EWTD) on the operative experience of surgery residents
