An Extended Duration of the Pre-Operative Hospitalization is Associated with an Increased Risk of Healthcare-Associated Infections after Cardiac Surgery.

ABSTRACT: Nosocomial infections are a common complication in clinical practice with major impact on surgical success and patient outcome. The probability of nosocomial infections is rapidly increasing during hospitalization. Therefore, we investigated the impact of a prolonged pre-operative hospital stay on the development of post-operative infection. Within this prospective observational study, 200 patients scheduled for elective cardiac surgery were enrolled. Patients were followed during hospital admission and screened for the development of nosocomial infection. Logistic regression analysis was used to assess the impact of a prolonged pre-operative hospital stay on the development of infection. A total of 195 patients were suitable for the final analysis. We found a strong and direct association of the duration of pre-operative hospital stay and the number of patients developing infection (+23.5%; p?=?0.006). Additionally, the length of patients' pre-operative hospital stay was independently associated with the development of post-operative nosocomial infection, with an adjusted OR per day of 1.38 (95%CI: 1.02-1.86; p?=?0.036). A prolonged pre-operative hospital stay was significantly associated with the development of nosocomial infection after cardiac surgery. Those findings need to be considered in future clinical patient management in order to prevent unnecessary antibiotic use and potential harm to patients.

Project description:Infants and children undergoing open heart surgery routinely require multiple RBC transfusions. Children receiving greater numbers of RBC transfusions have increased postoperative complications and mortality. Longer RBC storage age is also associated with increased morbidity and mortality in critically ill children. Whether the association of increased transfusions and worse outcomes can be ameliorated by use of fresh RBCs in pediatric cardiac surgery for congenital heart disease is unknown.One hundred and twenty-eight consecutively transfused children undergoing repair or palliation of congenital heart disease with cardiopulmonary bypass who were participating in a randomized trial of washed versus standard RBC transfusions were evaluated for an association of RBC storage age and clinical outcomes. To avoid confounding with dose of transfusions and timing of infection versus timing of transfusion, a subgroup analysis of patients only transfused 1-2 units on the day of surgery was performed.Mortality was low (4.9%) with no association between RBC storage duration and survival. The postoperative infection rate was significantly higher in children receiving the oldest blood (25-38 d) compared with those receiving the freshest RBCs (7-15 d) (34% vs 7%; p = 0.004). Subgroup analysis of subjects receiving only 1-2 RBC transfusions on the day of surgery (n = 74) also demonstrates a greater prevalence of infections in subjects receiving the oldest RBC units (0/33 [0%] with 7- to 15-day storage; 1/21 [5%] with 16- to 24-day storage; and 4/20 [20%] with 25- to 38-day storage; p = 0.01). In multivariate analysis, RBC storage age and corticosteroid administration were the only predictors of postoperative infection. Washing the oldest RBCs (> 27 d) was associated with a higher infection rate and increased morbidity compared with unwashed RBCs.Longer RBC storage duration was associated with increased postoperative nosocomial infections. This association may be secondary in part, to the large doses of stored RBCs transfused, from single-donor units. Washing the oldest RBCs was associated with increased morbidity, possibly from increased destruction of older, more fragile erythrocytes incurred by washing procedures. Additional studies examining the effect of RBC storage age on postoperative infection rate in pediatric cardiac surgery are warranted.

Project description:IntroductionFrailty is a geriatric syndrome characterised by reductions in muscle mass, strength, endurance and activity level. The frailty syndrome, prevalent in 25-50% of patients undergoing cardiac surgery, is associated with increased rates of mortality and major morbidity as well as function decline postoperatively. This trial will compare a preoperative, interdisciplinary exercise and health promotion intervention to current standard of care (StanC) for elective coronary artery bypass and valvular surgery patients for the purpose of determining if the intervention improves 3-month and 12-month clinical outcomes among a population of frail patients waiting for elective cardiac surgery.Methods and analysisThis is a multicentre, randomised, open end point, controlled trial using assessor blinding and intent-to-treat analysis. Two-hundred and forty-four elective cardiac surgical patients will be recruited and randomised to receive either StanC or StanC plus an 8-week exercise and education intervention at a certified medical fitness facility. Patients will attend two weekly sessions and aerobic exercise will be prescribed at 40-60% of heart rate reserve. Data collection will occur at baseline, 1-2 weeks preoperatively, and at 3 and 12 months postoperatively. The primary outcome of the trial will be the proportion of patients requiring a hospital length of stay greater than 7 days.Potential impact of studyThe healthcare team is faced with an increasingly complex older adult patient population. As such, this trial aims to provide novel evidence supporting a health intervention to ensure that frail, older adult patients thrive after undergoing cardiac surgery.Ethics and disseminationTrial results will be published in peer-reviewed journals, and presented at national and international scientific meetings. The University of Manitoba Health Research Ethics Board has approved the study protocol V.1.3, dated 11 August 2014 (H2014:208).Trial registration numberThe trial has been registered on ClinicalTrials.gov, a registry and results database of privately and publicly funded clinical studies (NCT02219815).

Project description:BackgroundProximal humerus fractures are among the most common presenting fractures to orthopedic surgeons in the USA. Hypoalbuminemia is accepted as a nutrition marker associated with post-operative complications following common orthopedic interventions.Questions/purposesThus, the authors sought to (1) describe the national demographic trends of patients undergoing surgical fixation for proximal humerus fracture and (2) investigate the association between pre-operative hypoalbuminemia, a malnutrition marker, and post-operative complications within 1 year of surgical intervention.MethodsThe PearlDiver Humana Claims Database was queried to identify a nationally representative cohort of patients who underwent surgical intervention for proximal humerus fractures from 2008 to 2015. Demographic and comorbid characteristics were collected. Pearson's χ-squared analysis was used to compare rates of 90-day and 1-year outcomes between hypoalbuminemia (albumin ≤ 3.5 mg/dL) and control groups. Multivariate logistic regression was then used to determine the isolated effect that hypoalbuminemia had on post-operative outcomes.ResultsOf the 3337 patients identified, 919 (27.5%) had available serum albumin data. Seventy (7.6%) patients had hypoalbuminemia. Hypoalbuminemia was more likely to be associated with post-operative sepsis (7.1% vs. 1.5%, respectively) and pneumonia (15.7% vs. 4.6) compared with controls. Additionally, hypoalbuminemia was associated with increased 90-day rates of discharge to extended care (4.3% vs. 0.8), emergency room visits (38.6% vs. 21.7), and total cost ($24,051.96 ± 24,972.74 vs. $15,429.74 ± 24,492.30).ConclusionOur study suggests hypoalbuminemia is associated with an increased risk of complications, specifically pneumonia and sepsis, and total health care costs in patients undergoing surgery for proximal humerus fractures. These findings provide insight for individualized patient care that will aid in evaluating the potential risk of surgical complications in an effort to improve outcomes and reduce costs.
