  abstract  = {Background All international guidelines recommend perioperative antibiotic prophylaxis (PAB) should be routinely administered to patients undergoing cardiac surgery. However, the duration of PAB is heterogeneous and controversial. Methods Between 01.01.2011 and 31.12.2011, 1096 consecutive cardiac surgery patients were assigned to one of two groups receiving PAB with a second-generation cephalosporin for either 56 h (group I) or 32 h (group II). Patients' characteristics, intraoperative data, and the in-hospital follow-up were analysed. Primary endpoint was the incidence of surgical site infection (deep and superficial sternal wound-, and vein harvesting site infection; DSWI/SSWI/VHSI). Secondary endpoints were the incidence of respiratory-, and urinary tract infection, as well as the mortality rate. Results 615/1096 patients (56,1\%) were enrolled (group I: n = 283 versus group II: n = 332). There were no significant differences with regard to patient characteristics, comorbidities, and procedure-related variables. No statistically significant differences were demonstrated concerning primary and secondary endpoints. The incidence of DSWI/SSWI/VHSI were 4/283 (1,4\%), 5/283 (1,7\%), and 1/283 (0,3\%) in group I versus 6/332 (1,8\%), 9/332 (2,7\%), and 3/332 (0,9\%) in group II (p = 0,76/0,59/0,63). In univariate analyses female gender, age, peripheral arterial obstructive disease, operating-time, ICU-duration, transfusion, and respiratory insufficiency were determinants for nosocomial infections (all ≤ 0,05). Subgroup analyses of these high-risk patients did not show any differences between the two regimes (all ≥ 0,05). Conclusions Reducing the duration of PAB from 56 h to 32 h in adult cardiac surgery patients was not associated with an increase of nosocomial infection rate, but contributes to reduce antibiotic resistance and health care costs.},

  abstract  = {Background Chronic kidney disease (CKD) is a common comorbid condition in coronary heart disease (CHD). CKD predisposes the patient to acute kidney injury (AKI) during hospitalization. Data on awareness of kidney dysfunction among CHD patients and their treating physicians are lacking. In the current cross-sectional analysis of the German EUROASPIRE IV sample we aimed to investigate the physician's awareness of kidney disease of patients hospitalized for CHD and also the patient's awareness of CKD in a study visit following hospital discharge. Methods All serum creatinine (SCr) values measured during the hospital stay were used to describe impaired kidney function (eGFR\(_{CKD-EPI}\) < 60 ml/min/1.73m2) at admission, discharge and episodes of AKI (KDIGO definition). Information extracted from hospital discharge letters and correct ICD coding for kidney disease was studied as a surrogate of physician's awareness of kidney disease. All patients were interrogated 0.5 to 3 years after hospital discharge, whether they had ever been told about kidney disease by a physician. Results Of the 536 patients, 32\% had evidence for acute or chronic kidney disease during the index hospital stay. Either condition was mentioned in the discharge letter in 22\%, and 72\% were correctly coded according to ICD-10. At the study visit in the outpatient setting 35\% had impaired kidney function. Of 158 patients with kidney disease, 54 (34\%) were aware of CKD. Determinants of patient's awareness were severity of CKD (OR\(_{eGFR}\) 0.94; 95\%CI 0.92-0.96), obesity (OR 1.97; 1.07-3.64), history of heart failure (OR 1.99; 1.00-3.97), and mentioning of kidney disease in the index event's hospital discharge letter (OR 5.51; 2.35-12.9). Conclusions Although CKD is frequent in CHD, only one third of patients is aware of this condition. Patient's awareness was associated with kidney disease being mentioned in the hospital discharge letter. Future studies should examine how raising physician's awareness for kidney dysfunction may improve patient's awareness of CKD.},
