[The use of RCGO triggers in the obstetric - gynecological procedures: the impact on the reduction of adeverse events. The experience of the Lombardia Region]. / L'utilizzo dei RCOG trigger in area ostetrica - ginecologica e la riduzione degli eventi avversi. L'esperienza della regione Lombardia.

The last few weeks of pregnancy are critical to a baby's health because important organs, including the brain and lungs, are not completely developed until the end of pregnancy. The adverse events during labor and childbirth can have very serious physical, psychological and financial consequences for the child, the family, health professionals and the whole community. These events can be reduced through interventions aimed at improving the safety and quality of care, based on evidence-based knowledge, guidelines and practices that must be widely and effectively applied. This work reports the experience of the Lombardy Region on improvement actions in the obstetric and gynecological procedures for the reduction of adverse events and sentinel events through the monitoring and management of the RCGS trigger tool.

The Clean Care Contest: promoting hand hygiene among healthcare and medical students.

INTRODUCTION: Despite continuing efforts, compliance rates and knowledge of best practices in hand hygiene remain disappointing. Recognizing that conventional educational tools seem out of touch with young people and that the med and messages contents need refreshing, the Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health devised a novel approach to promote the creation of innovative educational tools for improving knowledge of, and compliance with, hand hygiene rules among healthcare and medical students. METHODS: A contest in creating educational material on hand hygiene practices involved university students of nursing and medicine, and of other healthcare degrees. Students from the universities of the GISIO network were invited to create educational material (e.g., videos, posters, presentations, leaflets, and screensavers) to be presented by May 5th 2019 during the World Hand Hygiene Day / Save Lives: Clean Your Hands Global Annual Initiative of the World Health Organization). A local and a national winners were awarded. RESULTS: Three different local and national contests were performed during 2016, 2017 and 2018. During the three-year period, more than 270 educational tools have been developed: 130 (48%) were judged useful for hand hygiene promotion campaigns. The most frequent projects participating in the contests were videos (39%), posters (29%), leaflets (14%), and others (18%) submitted by more than 1,500 students of nursing (40%), medicine (31%), dentistry (7%), and of other healthcare courses in 14 universities. Products were evaluated by a local committee and, subsequently, local winners represented their University in a national contest. CONCLUSIONS: The contest provided a framework for the creation of innovative and potentially effective educational tools via an engaging approach that leveraged student creativity. Given the need to improve compliance rates, this study suggests that new ways can be advantageously explored to teach hand hygiene procedures and increase awareness of the importance of their consistent use among healthcare and medical students.

Willingness to pay for risky lifestyles: results from the Pay for Others (PAY4O) study, Italy.

OBJECTIVES: We assess the individual willingness to pay for diseases arising from risky lifestyles and investigate the personal factors that influence such willingness. STUDY DESIGN: We conducted an online survey with 821 respondents in Italy. The questionnaire was distributed via Facebook® in July and August 2016. The questionnaire covered sociodemographic characteristics, health status, behaviour and psychological attitudes, economic status, and opinion about covering the healthcare costs related to overeating, unhealthy diet, sedentary lifestyles, alcohol abuse, tobacco smoking, driving under the influence of alcohol, and illegal drug use by. METHODS: We performed the following: (1) the study of the patterns in the dependent variables by principal component analysis; (2) analysis of the determinants by Holdout Variable Importance measure obtained in Random Forest; and (3) we used ordered logit models. RESULTS: Participants agreed with the idea that public health care should be provided for problems arising from bad eating habits and sedentary lifestyle (50.4%), whereas the health care consequences of the other risky behaviours should not be publicly financed by the Italian National Health Service. CONCLUSIONS: Our study gives an overview of the willingness to pay of a population living in a country where financing of the Health Service is based on general taxation. So, these results may be generalized, with due caution, to all the countries where the Health Service offers universal coverage and is operated by the government, but of course not to scenarios related to market-based or social health insurance systems.

Evidence-Based Medicine and Clinical Practice: the first Italian attempt to define the appropriateness of rehabilitation admission criteria through the application of the Delphi method.

BACKGROUND: One of the consequences of today's global economic crisis is the need to control healthcare spending, in particular by improving the level of appropriateness. Thus, admission to rehabilitation has become an issue, especially as regards inappropriateness of resource allocation. The scientific literature suggests that more attention should be paid to the problem of clinical appropriateness in order to better identify the patients' actual needs. For the first time in Italy, this study aims at defining the appropriateness of intensive rehabilitation admission criteria through use of the Delphi method involving a panel of national experts. MATERIAL AND METHODS: A three-round Delphi survey was conducted according to international guidelines. Electronic questionnaires were individually sent via e-mail to ensure the participants' anonymity throughout the process. Questions were mostly based on rehabilitation literature. RESULTS: During the Delphi process, a total of 79 items were submitted to a heterogenous panel of rehabilitation experts who were asked to express their level of agreement to the item contents on a five-point Likert scale. At the end of the survey, a list of 19 appropriate criteria for admission to intensive rehabilitation facilities and 21 reasons for inappropriateness was drawn up. CONCLUSION: This study represents the first attempt in Italy to define shared and objective appropriateness criteria for admission to intensive rehabilitation. Out of the total number of experts invited to participate (31), only 16 completed the entire survey. This poor participation rate unfortunately demonstrates the lack of awareness among Italian rehabilitation professionals, which is a further sign of both the scarcity of scientific evidence in this area and the need to reach consensus on admission criteria.

Measles surveillance activities in the Metropolitan Area of Milan during 2017-2018.

INTRODUCTION: In Italy, the transmission of measles is still endemic, and 7,919 cases were reported to the National Surveillance System between January 2017 and December 2018. Aim of this study is to report the results of the measles surveillance activities in the Metropolitan City of Milan from March 2017 to December 2018, and to evaluate the surveillance performance WHO indicators. METHODS: The Local Health Units (LHUs) carried out case investigations and collected specimens to send to the EpiSoMI Lab (Subnational Reference Laboratory, SRL) of the University of Milan for cases/outbreaks confirmation and genotyping performed according to the WHO Guidelines. RESULTS: Overall, 610 suspected measles cases were reported by the surveillance system of the Metropolitan City of Milan. A total of 439 out of 540 cases with adequate specimens were laboratory-confirmed by molecular and/or serological assays. Two-hundred and thirty-six cases were notified as sporadic and 203 as related to 94 outbreaks. The most confirmed cases were aged 15-39 years, almost all not vaccinated. Overall, 282 cases were genotype D8 and 118 genotype B3.The evaluation of a set of indicators to monitor the quality of surveillance activities demonstrated the proficiency of the EpiSoMI Lab. CONCLUSIONS: A well-done investigation of cases and outbreaks by the surveillance local system, in a timely manner, in order to notify and investigate suspected cases and to laboratory confirm or discard cases is fundamental to reduce morbidity, to prevent further virus transmission and to achieve measles elimination.

Hospital clinical pathways for children affected by juvenile idiopathic arthritis.

BACKGROUND: Juvenile idiopathic arthritis (JIA) is the most common pediatric chronic rheumatic disease, which requires constant follow-up over the years, due to relapses during its progression. To maintain a good quality of life, it is important to limit admissions as far as possible. With the development of a Diagnostic Therapeutic Assistance Pathway (DTAP), we aim to select patients with suitable clinical conditions to be moved from routine hospital management to day care or outpatient treatment, evaluating the number of patients to whom this would apply. METHODS: Monocentric study regarding admissions for JIA between 2014 and 2016 in a Pediatric Unit of a university hospital in Milan. Through an analysis of the medical records, relevant information was extracted and collected in a Microsoft™ Excel database; starting from the data collected during the first year, a DTAP was prepared for patients with active arthritis and appropriate clinical conditions. RESULTS: The study includes data from 223 JIA hospitalization cases involving 127 patients. Applying DTAP criteria, 32% patients would have avoided admissions and 23% would have been admitted less frequently. The data concerning the activities of the Unit for JIA patients showed a relevant drop in the number of hospitalizations since 2015, from 89 in 2014 to 66 and 68 in 2015 and 2016 respectively. CONCLUSION: The opportunity offered by DTAP, has suggested feasible changes in hospitalization management and it's use would promote the possibility of treating the children without hospitalization, or minimizing it. In conclusion DTAP application is a priority for the continuous improvement of clinical practice and quality of life for patients and their families.

Hospital Hygiene and Infection Prevention and Control in Italy: state of the art and perspectives.

Although hospital hygiene has a long history in Italy it is necessary to reflect about it because of the innovation in healthcare systems and because of the evolution due to European Union related activities. Different traditions exist in European countries about hospital hygiene and European Centre for Disease Prevention and Control (ECDC) adopted the term of "infection control and hospital hygiene" which includes all the engaged European healthcare professionals. We propose to modify hospital hygiene as "healthcare organisation hygiene" in order to focalise the attention to all care settings not only hospitals and to adopt the following definition: "all activities aimed to guarantee, in an appropriate, scientifically sound and efficient way, that structures and processes support healthcare practices in a safe comfortable and healthy environment both for patients, caregivers and healthcare workers". Hospital hygiene and its professionals, besides the long tradition, still remain a relevant pillar in guaranteeing quality and safety of healthcare in Italy.

Epidemiology of intensive care unit-acquired sepsis in Italy: results of the SPIN-UTI network.

BACKGROUND: Sepsis is the major cause of mortality from any infectious disease worldwide. Sepsis may be the result of a healthcare associated infection (HAI): the most frequent adverse events during care delivery especially in Intensive Care Units (ICUs). The main aim of the present study was to describe the epidemiology of ICU-acquired sepsis and related outcomes among patients enrolled in the framework of the Italian Nosocomial Infections Surveillance in ICUs - SPIN-UTI project. STUDY DESIGN: Prospective multicenter study. METHODS: The SPIN-UTI network adopted the European protocols for patient-based HAI surveillance. RESULTS: During the five editions of the SPIN-UTI project, from 2008 to 2017, 47.0% of HAIs has led to sepsis in 832 patients. Overall, 57.0% episodes were classified as sepsis, 20.5% as severe sepsis and 22.5% as septic shock. The most common isolated microorganisms from sepsis episodes were Acinetobacter baumannii, Klebsiella pneumoniae and Pseudomonas aeruginosa. The case fatality rate increased with the severity of sepsis and the mean length of ICU-stay was significantly higher in patients with ICU-acquired sepsis than in patients without. CONCLUSION: Our study provides evidence that ICU-acquired sepsis occurs frequently in Italian ICU patients and is associated with a high case fatality rate and increased length of stay. However, in order to explain these findings further analyses are needed in this population of ICU patients.

Results of a survey of procedures for cleaning and disinfecting ambulances.

BACKGROUND: In 2014, the Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health (GISIO-SItI), in collaboration with the National Association of Medical Hospital Managers (ANMDO), conducted a survey on the availability of procedures for cleaning and disinfecting ambulances in order to assess the practices in use. METHODS: An online questionnaire was prepared through the Survey Monkey® platform and a web link access was sent to a convenience sample of ANMDO doctors working in healthcare management in public and private healthcare facilities. RESULTS: Ninety-six questionnaires were collected (26% response rate). In 73% of cases there was a procedure for cleaning and disinfecting ambulances, which had been produced at a company level (67%) and involved various professionals. In 21% of cases the procedure had been prepared in expectation of an epidemic or following an epidemic (5%). The recommendations had been presented to the staff (90%), in 28% of cases through training events with verification of the knowledge acquired. Monitoring of the implementation of the procedure is planned in the majority of cases (88%), mainly through direct observation (92%). In 67% of cases the tender specifications for ambulance services did not include a section dedicated to cleaning and disinfection and, in the absence of a procedure, this was provided by the hospital in only 51% of case. CONCLUSION: This survey represented a first step towards the development of guidelines for standardising procedures and providing indications useful for their evaluation and monitoring their implementation.

Heating, ventilation and air conditioning (HVAC) system, microbial air contamination and surgical site infection in hip and knee arthroplasties: the GISIO-SItI Ischia study.

BACKGROUND: Recent studies have questioned the role of unidirectional airflow ventilation system in reducing surgical site infection (SSI) in prosthetic implant surgery. The aim of the ISChIA study ("Infezioni del Sito Chirurgico in Interventi di Artroprotesi" which means "Surgical site infections in arthroplasty surgery") was to evaluate, as a contribution to this debate, the association between heating, ventilation and air conditioning systems, microbial air contamination and surgical site infection in hip and knee arthroplasty. METHODS: The study was performed from March 2010 to February 2012 in 14 hospitals, for a total of 28 operating theatres: 16 were equipped with vertical unidirectional airflow ventilation (U-OTs), 6 with mixed airflow ventilation (M-OTs), 6 with turbulent airflow ventilation (T-OTs). Microbial air contamination in the operating theatre was evaluated by means of passive (Index of Microbial Air contamination, IMA) and active (Colony Forming Units per cubic metre, cfu/m3) sampling. SSI surveillance was carried out according to the Hospitals in Europe Link for Infection Control through Surveillance protocol. RESULTS: A total of 1,285 elective prosthesis procedures (61.1% hip and 38.9% knee) were included in the study. The results showed a wide variability of the air microbial contamination in operating theatres equipped with unidirectional airflow. The recommended values of ≤2 IMA and ≤10 cfu/m3 were exceeded, respectively, by 58.9% and 46.4% of samples from U-OTs and by 87.6% and 100% of samples from M-OTs. No significant difference was observed between SSI cumulative incidence in surgical procedures performed in U-OTs compared with those performed in T-OTs. A lower risk of SSI, even though not statistically significant, was shown in surgical procedures performed in U-OTs with a microbial air contamination within the recommended values (≤2 IMA and ≤10 cfu/m3) compared with those performed in U-OTs where these limits were exceeded, and compared with those performed in T-OTs with microbial air contamination within the recommended values for this type of OTs (≤25 IMA, ≤180 cfu/m3. CONCLUSION: ISChIA study did not show a protective effect of unidirectional airflow compared with turbulent airflow in arthroplasty surgery. However, the frequent exceeding of recommended air microbial contamination values in OTs equipped with unidirectional airflow, and the lower SSI risk in surgical procedures performed in compliant U-OTs compared with those performed in non-compliant U-OTs and with those performed in compliant T-OTs, suggest the need of further studies, which should consider air microbial contamination and other aspects of SSI prevention that may negate the potential benefits of the ventilation system; differences in intrinsic and extrinsic risk factors, medical treatment and surgical technique are also to be considered. Training interventions aimed at improving the behaviour of operators are essential.

Hospital hygiene in Italy: the GISIO-SItI survey.

BACKGROUND: In Italy there are no rules concerning the establishment of a hospital hygiene structure in hospitals and other healthcare settings, and the hospital organization plans vary widely. The aim of the survey, carried out by the Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene, Preventive medicine and Public health, was to evaluate the presence in the hospital organization plan of a structure referred to as Hospital hygiene, or including in its denomination the words "hygiene" or "hospital hygiene", the activities carried out, the relation to other areas, like patient safety, the type and quantity of professionals involved, the strengths and the critical aspects. METHODS: A semi-structured questionnaire was administered to Healthcare Trusts representing all Italian Regions through the members of the above Study Group. RESULTS: 35 Trusts, 13 in Northern, 8 in Central, 14 in Southern Italy (including Sicily and Sardinia), completed the questionnaire. In 19 Trusts (54.3%) a structure whose denomination included the words "hospital hygiene" or "hygiene" was present. The activities related to the management of infectious risk were most represented, carried out autonomously or in collaboration, but many other activities were covered. In all hospitals the activities of the Hospital Hygiene Unit inter-linked with those of the clinical risk, with different forms of collaboration. CONCLUSION: This survey, even though on a limited sample, provided a picture of hospital hygiene at a national level, showing a considerable heterogeneity and highlighting critical issues but also strengths. It is essential to share organizational and management models that enhance and promote hospital hygiene, to ensure the appropriateness of healthcare practices offered in a safe and comfortable environment to patients, operators, and visitors.

Essential strategies in HAI prevention and control: performance assessment through the implementation of the HAI-CoSIP tool of the GISIO-SItI group. A pilot study in a sample of Italian Organizations.

BACKGROUND: Healthcare-Associated Infections are a great concern for worldwide healthcare systems and represent a considerable threat to patient safety, leading to adverse clinical outcomes. A defined panel of indicators represents a key element to guide Healthcare Organizations towards identification of main gaps, implementation of effective actions and continuous improvements on Healthcare-Associated Infections prevention and control activities. A review on accreditation systems conducted by the Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene Preventive Medicine and Public Health revealed a substantial heterogeneity of implemented standards and led to the development of a core set of indicators and requirements for Healthcare-Associated Infections' prevention and control within the hospital setting. The main aim of the study was to test the feasibility of the Healthcare-Associated Infections' prevention and control within the hospital setting tool to calculate performance scores on a sample of Italian Healthcare Organizations and to identify major critical issues. The potential benefits of the possibility of future implementation of the tool within Institutional Accreditation Programs is discussed. STUDY DESIGN: Cross sectional pilot survey. METHODS: The Healthcare-Associated Infections' prevention and control within the hospital setting included 96 criteria and 20 key areas including an area for outcomes indicators. For applicable criteria, standards fulfilment was evaluated according to a 4 point Likert scale. A composite score was calculated for each Healthcare Organization and five performance levels were identified. Data were further analysed by computing performance scores at the level of each area and requirement. RESULTS: 20 Healthcare Organizations agreed to take part in this pilot study including two rehabilitative Healthcare Organizations. Among the whole sample a mean of 12.20% of requirements resulted not fulfilled, leaving space for further improvements. Critical areas were easily identified and the instrument was able to capture substantial differences between Healthcare Organizations. Only a few number of standards resulted "Not Applicable" (Mean = 4.71%) and most of them regarded Rehabilitative Healthcare Organizations. Mean composite performance index resulted 74.06% (SD = 16.96, range 36.30 - 94.27%); area of outcome indicators obtained a mean score of 56.17. CONCLUSION: The Healthcare-Associated Infections' prevention and control within the hospital setting resulted an useful tool to assess Healthcare Organizations' performance in the field of Healthcare-Associated Infections prevention and control and to identify necessary actions for further improvements. The distribution of total scores by Healthcare Organizations showed a high heterogeneity. Implementation of the Healthcare-Associated Infections' prevention and control within the hospital setting tool as an institutional accreditation tool may help to drive the required harmonization at a national level of Healthcare-Associated Infections management and control strategies and overcome current substantial regional differences.

Knowledge, experiences, and attitudes toward Mantoux test among medical and health professional students in Italy: a cross-sectional study.

BACKGROUND: The World Health Organization's Action Framework for tuberculosis elimination in low-tuberculosis incidence countries includes the screening for active and latent tuberculosis in selected high-risk groups, including health care workers. In this context, medical and health profession students, exposed to nosocomial tuberculosis transmission during training and clinical rotations, are target populations for tuberculosis screening. No updated data are available on tuberculosis screening practice and knowledge of medical and health profession students in Italy. METHODS: Within the activities Italian Study Group on Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health, we carried out a multicentre cross-sectional study to assess knowledge, attitude and practices on tuberculosis prevention and control among Medical, Dentistry, Nursing and other health professions' students. Students were enrolled in the study on a voluntary basis and were administered a previously piloted structured questionnaire. Logistic regression models were applied to explore knowledge on tuberculosis prevention by selected socio-demographic variables and University-based tuberculosis prevention practice. RESULTS: Students of seventeen Universities across Italy participated in the study, and 58.2% of them received compulsory tuberculin skin test either at enrollment or while attending clinical practice. A total of 5,209 students filled the questionnaire. 37.7% were medicine and dentistry students (Group 1), 44.9% were nursing students (Group 2) and 17.4% were other health professions' students (Group 3). Age and gender had different distributions by groups, as well as knowledge and practice on tuberculin skin test. 84.4% of the study population (95% CI = 83.3-85.3) was aware of the existence of the tuberculin skin test, 74.4% (95% CI = 73.2-75.6) knew what is the first-level screening test for latent tuberculosis and only 22.5% (95% CI = 21.4-23.6) knew how to proceed after a positive tuberculin skin test result. Overall, knowledge on tuberculosis prevention was higher in Group 2 and lower Group 3, as compared to Group 1. CONCLUSION: In Italy, the knowledge on tuberculosis screening among University students is generally good. To reduce some of the criticalities found among the different study courses, it would be appropriate to harmonize both the regulations on tuberculosis screening practices for admission to University courses, and the educational activities on the topic of tuberculosis, to be extended to all workers involved in health care setting.

The effectiveness of educational interventions in university training on hospital hygiene: results of action research.

BACKGROUND: The Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health promoted and conducted a study on teaching hospital hygiene, with particular reference to the prevention and control of healthcare-associated infections, with the aim of developing effective educational material starting from the results collected. MATERIAL AND METHODS: First of all, a survey was carried out, targeting lecturers in hospital hygiene, with the purpose of investigating their perceptions regarding this issue. The available scientific literature was also reviewed in order to identify effective educational/teaching strategies for the prevention of healthcare-associated infections, so that valid training interventions could be subsequently developed. Finally, a trial-training intervention was implemented, and specific audio-visual teaching material was also tested. RESULTS: The overall response rate to the survey was 42%, with good country-wide representativeness. The level of awareness of hospital hygiene issues by students resulted higher among trainee nurses (65%) than among medical students (44%). The teaching staff identified alternative educational methodologies to substitute the classical lecture (e.g.: case discussions) and, in most cases, the alternative solution appeared to be preferable. The teaching of hospital hygiene was better integrated with other disciplines and professional training activities in the degree courses for nurses than in those for doctors; the total number of hours assigned to such teaching was variable. The literature review highlighted that various educational approaches are used. The most common are presentations or lectures, but videos, posters, questionnaires and e-learning strategies are also used. Combining different instruments when designing an educational programme has proven to be an effective strategy. The training activity tested was positively evaluated by the participants; the possibility of multidisciplinary exchange of knowledge was particularly appreciated. CONCLUSION: Having considered the issue of teaching hospital hygiene from the points of view of the different protagonists involved (educators and students), this enabled us to develop useful training material and a proposal for a shared educational intervention. The subject of hospital hygiene, in particular the one related to the prevention of healthcare-associated infections, is addressed in various courses and with different modalities; it is, therefore, important to standardize course contents and teaching methods, in order to facilitate multidisciplinary debate, especially starting from case studies.

Definition of criteria and indicators for the prevention of Healthcare-Associated Infections (HAIs) in hospitals for the purposes of Italian institutional accreditation and performance monitoring.

BACKGROUND: Healthcare-associated infections (HAIs) are an important issue in terms of quality of care. HAIs impact patient safety by contributing to higher rates of preventable mortality and prolonged hospitalizations. In Italy, analysis of the currently available accreditation systems shows a substantial heterogeneity of approaches for the prevention and surveillance of HAIs in hospitals. The aim of the present study is to develop and propose the use of a synthetic assessment tool that could be implemented homogenously throughout the nation. METHODS: An analysis of nine international and of the 21 Italian regional accreditation systems was conducted in order to identify requirements and indicators implemented for HAI prevention and control. Two relevant reviews on this topic were further analyzed to identify additional evidence-based criteria. The project team evaluated all the requirements and indicators with consensus meeting methodology, then those applicable to the Italian context were grouped into a set of "focus areas". RESULTS: The analysis of international systems and Italian regional accreditation manuals led to the identification respectively of 19 and 14 main requirements, with relevant heterogeneity in their application. Additional evidence-based criteria were included from the reviews analysis. From the consensus among the project team members all the standards were compared and 20 different thematic areas were identified, with a total of 96 requirements and indicators for preventing and monitoring HAIs. CONCLUSIONS: The study reveals a great heterogeneity in the definition of accreditation criteria between the Italian regions. The introduction of a uniform, synthetic assessment instrument, based on the review of national and international standards, may serve as a self-assessment tool to evaluate the achievement of a minimum standards set for HAIs prevention and control in healthcare facilities. This may be used as an assessment tool by the Italian institutional accreditation system, also useful to reduce regional disparities.

Risk of surgical site infections following hip and knee arthroplasty: results of the ISChIA-GISIO study.

BACKGROUND: Surgical Site Infection (SSI) is one of the major complications following insertion of hip or knee prosthesis. The aim of the present study was to describe rates of SSIs and associated risk factors during hip and knee prosthesis procedures in Italian hospitals. METHODS: Italian hospitals were invited to join the ISChIA (Surgical Site Infections in Arthroplasty Surgery) project and participated in the study on a voluntary basis. SSI surveillance was performed according to the Hospitals in Europe Link for Infection Control through Surveillance (HELICS) -SSI protocol. The study population consisted of all patients who had a prosthetic knee or hip joint replacement between March 2010 and February 2011. Only elective operations were include. RESULTS: A total of 14 hospitals and 1285 surgical procedures were included. SSI cumulative incidence was 1.3 per 100 hip and 2.4 per 100 knee surgical procedures; a significant positive trend of SSI incidences was observed with increasing SSI risk index. In multivariate analysis, considering hip procedures, the single independent risk factor associated to SSI was operation length (RR: 4.54; 95%CI: 1.06-19.48). For knee procedures, no significant risk factor was identified. CONCLUSIONS: In the present study, SSI cumulative incidence was in the range of European data. However, a larger number of operations is needed to better estimate SSI rates. A second edition of the ISChIA project has been already conducted and results of the two surveys will provide new insight to further our knowledge for infection control.

Surgical site infections in oncologic orthopaedic prosthetics surgery.

BACKGROUND: Literature reports an incidence of surgical site infections (SSIs) in oncological patients undergoing prosthetic replacement between 8% and 35% after first implantation and 43% after revision. The purpose of this retrospective study, conducted at the oncologic orthopaedic unit of G. Pini Orthopaedic Hospital in Milan, was to evaluate: - number of SSIs in oncological megaprosthetic reconstruction between 2008 and 2011, - possible risk factors associated with the onset of SSIs, - antibiotic prophylaxis applied. DESIGN AND METHODS: We reviewed medical records of patients who underwent megaprosthetic reconstruction and collected data on whole treatment and follow up after discharge, focusing on possible risk factors implied in the onset of SSIs such as patient characteristics, site of surgery, duration of surgery, number of persons in the operating room, size of resection, antibiotic prophylaxis. We recorded every SSI which met the criteria set by the Hospital in Europe Link for Infection Control through Surveillance (HELICS) protocol. RESULTS: One-hundred and eleven surgeries were evaluated. Administration of prophylaxis was generally recorded and continued postoperatively for an average of 18.89 days, often depending on the length of the post-surgical stay. Mean duration of surgery was 254 minutes with an average of 7 persons attending the operating room. We recorded 6 SSIs.

Operating theatre ventilation systems and microbial air contamination in total joint replacement surgery: results of the GISIO-ISChIA study.

BACKGROUND: Recent studies have shown a higher rate of surgical site infections in hip prosthesis implantation using unidirectional airflow ventilation compared with turbulent ventilation. However, these studies did not measure the air microbial quality of operating theatres (OTs), and assumed it to be compliant with the recommended standards for this ventilation technique. AIM: To evaluate airborne microbial contamination in OTs during hip and knee replacement surgery, and compare the findings with values recommended for joint replacement surgery. METHODS: Air samplings were performed in 28 OTs supplied with unidirectional, turbulent and mixed airflow ventilation. Samples were collected using passive sampling to determine the index of microbial air contamination (IMA). Active sampling was also performed in some of the OTs. The average number of people in the OT and the number of door openings during the sampling period were recorded. FINDINGS: In total, 1228 elective prosthesis procedures (60.1% hip and 39.9% knee) were included in this study. Of passive samplings performed during surgical activity in unidirectional airflow ventilation OTs (U-OTs) and mixed airflow OTs (M-OTs), 58.9% and 87.6% had IMA values >2, respectively. Of samplings performed during surgical activity in turbulent airflow OTs (T-OTs) and in turbulent airflow OTs with the surgical team wearing Steri-Shield Turbo Helmets (TH-OTs), 8.6% and 60% had IMA values ≤ 2, respectively. Positive correlation was found between IMA values and the number of people in the OT and the number of door openings (P < 0.001). In addition, correlation was found between active and passive sampling (P < 0.001). CONCLUSION: These findings challenge the belief that unidirectional systems always provide acceptable airborne bacterial counts.

Reinforcing good practice: Implementation of guidelines at hospital G. Pini.

INTRODUCTION: Surgical site infections (SSIs) in orthopaedic surgery are a demanding complication for the patient and in terms of economics. Many guidelines (GLs) are available on antibiotic prophylaxis as an effective preventive measure; however, these GLs are often ignored in practice. A surveillance study of SSIs in arthroplasty, promoted by the Italian Study Group of Hospital Hygiene of the Italian Society of Public Health (SitI), showed a high percentage of non-adherence to GLs on antibiotic prophylaxis. OBJECTIVES: The purpose of this study was to review the existing GLs, share them within the hospital and then monitor their implementation. MATERIALS AND METHODS: Information and training are considered to be great tools for implementation and sharing of GLs, which leads to significant improvements in clinical practice. A multidisciplinary team comprising infectious disease specialists, orthopaedic surgeons, nurse epidemiologists and public health specialists was established at the G. Pini Hospital in Milan to revise GLs, and to organise educational events for their implementation, sharing and dissemination. A checklist was devised for monitoring purposes. RESULTS: GLs were presented to orthopaedic surgeons and nurse coordinators during two educational events. Meetings were organised in each unit to present the results of the surveillance of SSIs in arthroplasty and to discuss the reasons why the prophylaxis regimens adopted were not consistent with GLs. It was emphasised that the most important issue, on which there is consensus in the scientific literature, was related to the duration of prophylaxis beyond 24h. The review process for GLs was presented and pocket-sized GLs were given to surgeons. The importance of documenting on medical record any deviations from the GLs was emphasised. CONCLUSIONS: Any changes in behaviour in clinical practice must be monitored and evaluated regularly. The monitoring of GLs in terms of correct choice of drug, timing of administration and duration of prophylaxis is made using a special checklist on a representative sample of medical records.

To measure, evaluate and improve: four years long health records self-control activity at G. Pini Orthopedics Institute.

BACKGROUND: A health record, when properly handled, can be considered in all respects as an important tool that tracks the course of hospitalization, clinical aspects and the commitment of resources employed in the execution of the episode itself. METHODS: Lombardy Region has established, since 2009, that each hospital carry out a self-assessment of their documentation. The objective of self-control is to monitor the completeness and accuracy of documentation and to highlight the congruence in order to implement corrective activities to reduce the inappropriateness. RESULTS: The four years of self-control activities carried out in our Institute show that following the implementation of a supervisory and monitoring system, it was possible to report a statistically significant difference between the percentage of records deemed to comply in the first survey year (2009) and the last year considered (2012). It passes, that is, from 2.9% of conforming clinical records to 68.8% that do not conform. CONCLUSIONS: This trend is suggestive in confirming, as a whole, the effectiveness of internal controls, structured and repeated over time, which evaluate the completeness of the documentation and generate the appropriate corrective actions.
