Abstract
OBJECTIVE Surgical site infections (SSIs) are associated with protracted hospitalisation, antibiotics administration, and increased morbidity and mortality. This work investigated the incidence rate of SSIs in the Department of General Surgery at the University Hospital of Ioannina, Greece, the associated risk factors and pathogens responsible. METHOD In this prospective cohort study, patients who underwent elective procedures under general anaesthesia were enrolled. Risk factors monitored included age, sex, body mass index, smoking, alcohol consumption, preoperative length of stay, chemoprophylaxis, intensive care unit (ICU) stay, American Society of Anesthesiology (ASA) score, and the National Nosocomial Infections Surveillance System (NNIS) basic SSI risk index. RESULTS Of the 1058 enrolled patients, 80 (7.6%) developed SSIs. Of the total cohort, 62.5% of patients received chemoprophylaxis for >24 hours. A total of 20 different pathogens, each with multiple strains (n=108 in total), were identified, 53 (49.5%) Gram-negative rods, 46 (42%) Gram-positive cocci, and nine (8.4%) fungi (Candida spp.). Escherichia coli was the prevalent microorganism (24.3%). SSI-related risk factors, as defined by univariate analysis, included: ICU stay, ASA score >2 (p<0.001), NNIS score >0, and wound classes II, III, and IV. Also, serum albumin levels <3.5g/dl were associated with increased rate of SSIs. The multivariate model identified an NNIS score of >0 and wound classes II, III, and IV as independent SSI-related risk factors. CONCLUSION This study showed high SSI rates. Several factors were associated with increased SSI rates, as well as overuse of prophylactic antibiotics. The results of the present study could be a starting point for the introduction of a system for recording and actively monitoring SSIs in Greek hospitals, and implementation of specific guidelines according to risk factors.

Abstract
BACKGROUND In Greece there is no systematic assessment of surgical wounds with the use of a validated instrument, while the ASEPSIS scoring method has been widely used internationally. AIM To examine the frequency of wound infections and their correlations both with patient background factors, as well as surgery factors, with the use of ASEPSIS. METHODS In this prospective, observational study, participants undergoing orthopaedic surgeries in a large hospital in Greece were assessed during hospitalisation and the first month after discharge using the ASEPSIS wound assessment tool. The principles of the Declaration of Helsinki were applied. Non-parametric statistical analyses were performed using SPSS 20.0. RESULTS In total, 111 patients participated; nearly half (49.5%) had a total ASEPSIS score of "0". Almost 3 out of 4 patients (76.6%) had an ASEPSIS score under or equal to "10" (satisfactory healing) and only 3.6% had a minor or severe surgical wound infection. The ASEPSIS score was only positively correlated to longer surgery duration and longer postoperative stay. DISCUSSION The frequency of surgical wound infections in orthopaedic patients in Greece is comparable to that described in the literature. ASEPSIS could be used for assessing patients and as a performance indicator in Greek orthopaedic departments.

Abstract
Objective.To estimate the rate of surgical site infection (SSI) occurring after hospital discharge, to evaluate whether limiting surveillance to inpatients underestimates the true rate of SSI, and to select surgical procedures that should be included in a postdischarge surveillance program.Design.Prospective surveillance study.Setting.A surgical ward at a university teaching hospital in Italy.Patients.A total of 264 surgical patients were included in the study.Results.The global SSI rate was 10.6% (28 patients); 17 (60.2%) of patients with an SSI developed the infection after hospital discharge. The overall mean length of postoperative stay (±SD) for patients who acquired a postdischarge SSI was 4.9 ± 3.7 days, and SSI was diagnosed a mean duration (±SD) of 11.5 ± 4.5 days after surgery. Among procedures with postdischarge SSIs, those classified by the National Nosocomial Infections Surveillance system (NNIS) as herniorrhaphy, mastectomy, other endocrine system, and other integumentary system were associated with a mean postoperative stay that was less than the mean time between the operation and the onset of SSI. Four (36%) of in-hospital SSIs occurred after procedures with an NNIS risk index of 0, and 7 (64%) occurred after procedures with an NNIS risk index of 1 or higher. Of the 17 SSIs diagnosed after discharge, 14 procedures (82%) had an NNIS risk index of 0, compared with 3 procedures (18%) with an NNIS risk index of 1 or higher.Conclusions.Our results revealed an increased risk of postdischarge SSI after some types of surgical procedures and suggest that there is an important need to change from generalized to NNIS operative category-directed postdischarge surveillance, at least for procedures locally considered to be high-risk.

Abstract
Objective.To examine the effect of heterogeneous case mix for a benchmarking analysis and interhospital comparison of the prevalence rates of nosocomial infection.Design.Cross-sectional survey.Setting.Eleven hospitals located in Cyprus and in the region of Crete in Greece.Methods.The survey included all inpatients in the medical, surgical, pediatric, and gynecology-obstetrics wards, as well as those in intensive care units. Centers for Disease Control and Prevention criteria were used to define nosocomial infection. The information collected for all patients included demographic characteristics, primary admission diagnosis, Karnofsky functional status index, Charlson comorbidity index, McCabe- Jackson severity of illness classification, use of antibiotics, and prior exposures to medical and surgical risk factors. Outcome data were also recorded for all patients. Case mix-adjusted rates were calculated by using a multivariate logistic regression model for nosocomial infection risk and an indirect standardization method.Results.The overall prevalence rate of nosocomial infection was 7.0% (95% confidence interval, 5.9%–8.3%) among 1,832 screened patients. Significant variation in nosocomial infection rates was observed across hospitals (range, 2.2%–9.6%). Logistic regression analysis indicated that the mean predicted risk of nosocomial infection across hospitals ranged from 3.7% to 10.3%, suggesting considerable variation in patient risk. Case mix-adjusted rates ranged from 2.6% to 12.4%, and the relative ranking of hospitals was affected by case-mix adjustment in 8 cases (72.8%). Nosocomial infection was significantly and independently associated with mortality (adjusted odds ratio, 3.6 [95% confidence interval, 2.1–6.1]).Conclusion.The first attempt to rank the risk of nosocomial infection in these regions demonstrated the importance of accounting for heterogeneous case mix before attempting interhospital comparisons.

Abstract
SUMMARYThe purpose of this study was to estimate the prevalence of healthcare-associated infections (HAIs) in the region of Western Greece and its relationship with possible predisposing factors. Two 1-day prevalence studies were performed in all hospitals of the region. The average HAI prevalence was 2·9% (range 0–6·8%) in the hospitals and 0–22·7% between different medical wards. Overall, 90% of HAI patients had predisposing factors. The most frequently isolated microorganism was Escherichia coli (14·3%). The study revealed a relatively low overall point prevalence of HAI, but remarkable discrepancies between the hospitals and wards. This may be due to the presence of confounding medical conditions and/or underreporting of HAIs from certain hospital wards. Local point-prevalence surveys may increase the awareness of HAIs in hospital staff and contribute to the establishment of effective infection control.

Abstract
PURPOSE To investigate the incidence and risk factors associated with the development of surgical site infections (SSIs) using the National Nosocomial Infection Surveillance (NNIS). METHODS A prospective cohort study was conducted at a tertiary health care center. Infection control personnel collected general and health care related data about patients. The NNIS risk index was calculated on the basis of data relating to the operation: wound contamination class, duration of surgery, and the American Society of Anesthesiologists (ASA) score. RESULTS A total of 5109 surgical procedures were included in the study. The overall cumulative incidence rate was 6.3%. The incidence of SSIs was 2.3% (63.5% of operative procedures), 8.3% (29.7%), 34.6% (6.2%), and 43.3% (0.6%), in patients with 0, 1, 2, and 3 risk index, respectively. The length of hospital stay (OR: 1.0; 95% CI: 1.053-1.075), preoperative length of stay (odds ratio [OR]: 1.9; 95% confidence interval [CI]: 1.953-1.981), antibiotic prophylaxis (OR: 2.5; 95% CI: 1.421-4.628), drainage (OR: 1.7; 95% CI: 1.360-2.353), ASA score (OR: 1.5; 95% CI: 1.235-1.946), class of wound contamination (OR: 2.0; 95% CI: 1.745-2.003), and NNIS risk index (OR: 1.3; 95% CI: 1.063-1.7) were independently associated with an increased risk for SSIs. Staphylococcus aureus was the most frequently isolated microorganism, 64% of them being methicillin-resistant. CONCLUSION The aim of this study was to investigate the most important risk factors associated with the development of surgical site infections (SSIs). Therefore, greater attention has been given to adherence to recommendations for the prevention and control of SSIs as well as to antibiotic prophylaxis protocols.

Abstract
BACKGROUND/AIM Nosocomial infections (NI) are a serious health problem resulting in an enromous burden of excess morbidity and mortaliti rates, and health care costs. The aim of this study was to assess the prevalence of NI and to identify groups of patients at special risk for NI in the University Clinical Center, Kragujevac, Serbia. METHODS A period prevalence study design was used in this study. A survey of NI included all patients hospitalized in all departments in the University Clinical Center, Kragujevac. RESULTS Among 764 patients surveyed, the global prevalence rate of patients with at least one NI was 6.2% (95% CI = 5.6-6.8), while the prevalence of NI was 7.1%. The most frequent infections were surgical site infections (14.1%; 95% CI = 12.9-15.3), followed by pneumonia (2.3%; 95% CI = 2.1-2.5) in surgical patients. In medical wards, the most common NI were skin and subcutaneous tissue infections (1.6%; 95% CI = 1.4-1.8), and urinary infections (1.4%; 95% CI = 1.3-1.5). Overall, 85.1% NI were culture-proven; the leading pathogens were Pseudomonas species (40.0%), followed by Staphylococcus species (25.0%), Escherichia coli (22.5%), Proteus mirabilis (17.5%) and Klebsiella-Enterobacter (12.5%). Multivariate logistic regression analysis identified 3 risk factors independently associated with NI appearance: hospital stay > or =8 days (p = 0.0015), urinary catheter (p = 0.0022) and antibiotic use (p < 0.001). CONCLUSION This study showed that NI are a serious health problem in our hospital. The most common infections were surgical site infections, followed by skin and subcutaneous tissue infection and urinary tract infections. Nosocomial infections were most common in patients in urological and orthopedic departments, and then in intensive care units. Prolonged hospital stay, urinary catheter and antibiotic exposure were risk factors independently associated with NI appearance.

Abstract
BACKGROUND In this first attempt to implement a standardized surveillance system of surgical site infections (SSI) in a Greek hospital, our objective was to identify areas for improvement by comparing main epidemiologic and microbiologic features of SSI with international data. METHODS The National Nosocomial Infections Surveillance (NNIS) system protocols were employed to prospectively collect data for patients in 8 surgical wards who underwent surgery during a 9-month period. SSI rates were benchmarked with international data using standardized infection ratios. Risk factors were evaluated by multivariate logistic regression. RESULTS A total of 129 SSI was identified in 2420 operations (5.3%), of which 47.3% developed after discharge. SSI rates were higher for 2 of 20 operation categories compared with Spanish and Italian data and for 12 of 20 categories compared with NNIS data. Gram-positive microorganisms accounted for 52.1% of SSI isolates, and Enterococci were predominant. Alarming resistance patterns for Enterococcus faecium and Acinetobacter baumannii were recorded. Potentially modifiable risk factors for SSI included multiple procedures, extended duration of operation, and antibiotic prophylaxis. SSI was associated with prolongation of postoperative stay but not with mortality. CONCLUSION Comparisons of surveillance data in our hospital with international benchmarks provided useful information for infection control interventions to reduce the incidence of SSI.

Abstract
Protein-energy malnutrition and nosocomial infection (NI) are frequent in elderly patients, and a causal link between the two has often been suggested. The aim of the present study was to identify the nutritional parameters predictive of NI in elderly patients. We assessed on admission 101 patients (sixty-six women, thirty-five men, aged over 65 years) admitted to an acute care of the elderly department. Sarcopenia was detected by dual-energy X-ray absorptiometry, with appendicular skeletal muscle mass expressed with respect to body area. Weight, BMI, albuminaemia, serum transthyretin and C-reactive protein values were also determined on admission, and known risk factors, such as functional dependence and invasive biomedical material, were also evaluated. After up to 3 weeks of hospitalisation, patients were classified according to whether they had developed an NI. After 3 weeks of hospitalisation, we found that twenty-nine patients had suffered an NI, occurring after a mean of 16.1 d. Patients who were sarcopenic on admission had a significantly higher risk of contracting an NI (relative risk 2.1, 95 % CI 1.1, 3.8). None of the other morphometric or biological parameters differed significantly between the two groups of patients on admission. Patients who experienced an NI were also more likely, on admission, to have a medical device (P=0.02 to P=0.001 depending on the device), to have swallowing problems (P=0.002) or to have restricted autonomy (P<0.01). Sarcopenia on admission to an acute care of the elderly unit, as measured by X-ray absorptiometry, was therefore associated with a doubled risk of NI during the first 3 weeks of hospitalisation.
