Surveillance for surgical site infection after hospital discharge : A surgical procedure-specific perspective

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.

Fish oil supplementation reduces cortisol basal levels and perceived stress: A randomized, placebo-controlled trial in abstinent alcoholics

Behavioral distress and dysfunctions of hypothalamic-pituitary-adrenocortical (HPA) axis play a central role in alcohol abuse. Omega-3 fatty acids are proposed as having antistress, regulatory effects on HPA responsiveness, but a possible protective role in ethanol addiction is unexplored.A randomized, doubleblind, placebo-controlled trial was performed in male alcoholics undergoing residential rehabilitation program, to evaluate the effects of 3-week supplementation with fish-oil providing eicosapentaenoic (60 mg/day) and docosahexaenoic acid (252 mg/day) on perceived stress/anxiety and HPA activity, assessed by measuring saliva basal cortisol levels at various daytimes (0730 h, 1130 h, 1600 h, 2000 h, and 2400 h) and the acute cortisol response to Trier Social Stress Test.Results showed that in supplemented subjects, before versus after decrease of stress/anxiety ratings was accompanied by reduction of cortisol basal levels throughout the day; no changes were observed in placebo group. At the end of intervention, amplitude, and duration of stress-evoked cortisol response did not differ between groups; however, the peak of cortisol response was temporally anticipated in supplemented subjects. In conclusion, an elevated omega-3 intake may reduce distress symptoms and basal cortisol secretion in abstinent alcoholics, thus providing a valid subsidiary measure to increase the efficacy of rehabilitation programs in ethanol addicts.

In)accuracy of blood pressure measurement in 14 Italian hospitals

Objectives: The diagnosis and control of hypertension depend on accurate measurement of blood pressure (BP). The literature on the accuracy of BP recording by health professionals is, however, limited, and no study directly interviewed patients in the hospital setting. This multicenter cross-sectional study aimed at evaluating the compliance to current recommendations on BP measurement by health professionals directly from patients and to investigate potential predictors of higher quality in BP recording. Methods: A trained nurse interviewed a random sample of adult patients hospitalized for an ordinary admission (except in the emergency room) lasting more than one night, without mental disorder, who had their BP routinely measured by the hospital personnel less than 3 h before. The questionnaire contained 15 items on the main procedures that are common to current guidelines. Results: Fourteen public hospitals from seven regions of Italy participated, and 1334 questionnaires were collected. Nine of the recommended practices were followed in the majority (>70%) of BP recordings, whereas some others were infrequent or rare: in 98.6, 82.2 and 81.1% of the participants, respectively, the arm circumference was never recorded, BP was measured only once, and BP was never recorded in both arms. Overall, 10 or more recommended procedures were followed during 33.4% recordings. At multivariate analysis, physicians were less likely than nurses to provide a more accurate BP measurement. Conclusions: The operators compliance to some recommendations in BP measurement is unacceptably low. This survey provides detailed indications for medical directors on the procedures and settings to prioritize in educational programs, which are definitely needed.

Perioperative antibiotic prophylaxis: improved compliance and impact on infection rates.

The aims of this study were to determine adherence to the perioperative antibiotic prophylaxis (PAP) protocol used at a large Italian teaching hospital during a 6-year period, to assess the variables associated with inappropriate administration, and to measure the impact on surgical site infection (SSI) rates. There were 28 621 patients surveyed of which 74·6% received PAP. An improvement in adherence to the PAP protocol was registered for 58·8% of patients. Significant risk factors were an American Society of Anesthesiologists (ASA) score ≥ 2 [odds ratios (OR) from 1·28 (95% confidence interval (CI) 1·19-1·37) to 1·87 (95% CI 1·43-2·44)], prolonged duration of surgery (OR 1·68, 95% CI 1·56-1·82) and urgent surgery (OR 2·16, 95% CI 1·96-2·37). During the study period, a significant reduction in SSIs rates was detected. We concluded that the global reduction of inadequate PAP administration signifies the efficacy of a multidisciplinary quality improvement initiative on antimicrobial utilization, and this is supported by the observed reduction of the SSI rate.

Determinants of influenza vaccination uptake among Italian healthcare workers

We analyzed seasonal influenza vaccination coverage among the Italian healthcare workers (HCW) in order to identify socio-demographic and clinical determinants of vaccination. We used data from the survey “Health and health care use in Italy,” which comprised interviews of 5,336 HCWs For each respondent, information on socioeconomic, health conditions, self-perceived health and smoking status were obtained. After bivariate analysis, we used multilevel regression models to assess determinants of immunization. Overall 20.8% of HCWs (95%CI 19.7–21.9) reported being vaccinated against seasonal influenza. After controlling for potential confounders, multilevel regression revealed that older workers have a higher likelihood of vaccine uptake (OR = 6.07; 95% CI 4.72–7.79). Conversely, higher education was associated with lower vaccine uptake (OR = 0.65; 95% IC 0.50–0.83). Those suffering from diabetes (OR = 2.07; 95% CI 1.19–1.69), COPD (OR = 1.95; 95% CI 1.31–2.89) and cardiovascular diseases (OR = 1.48 95% CI 1.11–1.96) were more likely to be vaccinated. Likewise, smokers, or former smokers receive more frequently the vaccination (OR = 1.40; 95% CI 1.15–1.70; OR = 1.54; 95% CI 1.24–1.91, respectively) compared with never-smokers as well as those HCWs reporting fair or poor perceived health status (ORs of 1.68, 95% CI 1.30–2.18). Vaccine coverage among HCWs in Italy remains low, especially among those with no comorbidities and being younger than 44 y old. This behavior not only raises questions regarding healthcare organization, infection control in healthcare settings and clinical costs, but also brings up ethical issues concerning physicians who seem not to be very concerned about the impact of the flu on themselves, as well as on their patients. Influenza vaccination campaigns will only be effective if HCWs understand their role in influenza transmission and prevention, and realize the importance of vaccination as a preventive measure

Surveillance of acute flaccid paralysis in the Marches region (Italy): 1997–2007

BackgroundThe last case of poliomyelitis due to transmission of indigenous wild poliovirus occurred in Italy in 1982, however, it is important to guarantee a high quality surveillance as there is a risk of importation of cases from areas where polio is endemic. Stopping poliovirus transmission is pursued through a combination of high infant immunization coverage and surveillance for wild poliovirus through reporting and laboratory testing of all cases of acute flaccid paralysis (AFP) among children under fifteen years of age. The aim of this study was to describe and to evaluate 11 years of active surveillance in the Marches (Italy) in terms of: incidence, aetiology and clinical manifestation of AFP cases.MethodsThe active Acute Flaccid Paralysis surveillance has been carried out in the Marches region since February 1997 by the Chair of Hygiene which established a regional hospital network. Active surveillance involves 15 hospital centres.ResultsIn the considered period, 0–15 years population varied between 187,051 in 1997 to 201,625 in 2007, so the number of AFP expected cases is 2 per year. From February 1997 to October 2007, 27 cases were found with rates of 1.0/100,000 in 1997; 2.0/100,000 in 1998; 1.0/100,000 in 1999; 0.5/100,000 in 2000; 2.5/100,000 in 2001; 1.0/100,000 in 2002; 0 in 2003; 0.5/100,000 in 2004; 1.5/100,000 in 2005; 2.0/100,000 in 2006; 1.5/100,000 in 2007. In 29.6% of cases two stool samples were collected in 14 days from the symptoms onset. The 60-days follow-up is available for 23 out of 27 cases reported. In 44.5% of cases the definite diagnosis was Guillain Barrè syndrome.ConclusionIn general, the surveillance activity is satisfactory even if in presence of some criticalities in biological samples collection. The continuation of surveillance, in addition to the maintenance of current levels of performance, will tend to a further and more detailed sensitization of all workers involved, in order to obtain spontaneous and prompt reporting, and to achieve the optimal standards recommended by the WHO both in the collection of biological samples and the availability of 60 days follow-up, with the goal of eradicating polio from all countries.

The effects of educational intervention on nutritional behaviour in alcohol-dependent patients.

AIMS To evaluate the nutritional status and the impact of an educational intervention on nutritional behaviour in alcohol-dependent patients. METHODS A pre-and post-intervention questionnaire and a follow-up interview were administered to 58 patients of a residential alcohol treatment service. RESULTS Females were at lower risk of being overweight than males, even after adjusting for amount and preferred type of alcohol beverage. Before intervention, 19% consumed 3 meals/day. Following the educational intervention, 22.2% of participants improved their knowledge. After 6 months, when 45 patients agreed to a telephone interview of whom 80% reported continued abstinence, 70.7% reported eating more than 3 meals/day. CONCLUSIONS Nutritional behaviour of alcohol patients after residential treatments improved during follow-up, and it is possible that an educational intervention to increase knowledge on healthy nutrition style may have contributed.

Reply to: Impact of laminar air flow on operating room contamination and surgical wound infection rates in clean and contaminated surgery

We would like to thank Barbadoro et al. for their response to our review article. Their letter addresses laminar airflow. Results in their letter demonstrate significant reductions in SSI rates when laminar air flow was used in ASA Grade 1 patients, in clean procedures and in patients who had procedures that had short (<1 h) operative times. These results are especially interesting when you consider that laminar airflow is generally the preserve of the orthopaedic surgeon where the aim is to reduce deep wound infections with prostheses in an elderly population, where operative times often exceed one hour. These results may illustrate the ability of laminar air flow to reduce the quantity of colony forming units in short operative periods to a level that patients who were otherwise well were able to combat. The breast is a clean-contaminated surgical site. Barbados et al.’s results only show significance for clean procedures and are therefore not directly relevant to breast implant surgery. We recognise that interventions like laminar air flow that we have “suggested” in our study were not supported by sufficient levels of evidence to make definitive recommendations, but we felt, where possible, these measures should be adopted. We commend Barbadoro et al.’s surveillance approach to such a contentious issue; an issue which has significant cost implications and which will only be truly evaluated using

Barriers to influenza vaccine uptake in obese people in Italy: Changes 2005-2013.

BACKGROUND Obesity is an independent risk factor for developing flu-related complications. OBJECTIVE The aim of this study was to analyze influenza vaccine uptake (VU) in the Italian obese, before and after the introduction of obesity among the national recommendations, and to evaluate factors associated to VU. METHODS The comparison of two editions of the national survey carried out in 2004-2005, before the inclusion of obese people among the specific high risk categories for flu complications, and in 2013, reaching a sample of 21,857 persons who declared to have a BMI>30. Multilevel logistic regression was used to evaluate potential independent predictors of influenza immunization. RESULTS Influenza vaccination coverage was 27.16% in 2013, versus 31.61% in 2005. A significant reduction of VU was registered after the introduction of obesity among the high risk conditions, for which flu VU was recommended. Regression modeling, both in adults and in older people, confirmed that barriers to VU in 2013 were younger age, medium level of education, absence of chronic disease, smoking habit, and reporting no contacts with GPs during the previous 12months. Among those aged 65 or more, the role of regional policies was associated to VU. CONCLUSIONS Immunization rates among young obese population are low, especially if not affected by comorbidities. Moreover, a reduction was registered in 2013 with respect to 2005. Flu vaccine uptake among the older population seems to be influenced by regional vaccination strategies. The development of novel strategy is warranted, especially among the young adults.
