The high incidence of hospital-acquired infections, about a tenth of which occur in wounds, has propelled the issue of prevention to the top of the health-care agenda. Policy centres on hygiene, protective precautions and educating staff and patients. This article focuses on detection and treatment options for confirmed wound infections.

Nosocomial infections are common in many hospital departments, but particularly so on the intensive care unit, where they affect some 20 to 30% of patients. While early diagnosis and appropriate treatment are, of course, important, perhaps the greatest challenge is in the application of techniques to limit the development of such infections. This review will briefly discuss some of the background pathophysiology and epidemiology of nosocomial infection, and then focus on general and infection-specific preventative strategies individually and as part of broader infection-control programs with infection surveillance.

OBJECTIVE: To determine the impact of the rotation of antimicrobial agents on the rates of infection, intestinal colonization, and acquisition with antimicrobial-resistant Gram-negative bacteria. DESIGN: Pre- and postintervention design. SETTING: A 19-bed, medical intensive care unit. PATIENTS: Individuals admitted to the study unit for >48 hrs. INTERVENTIONS: After a 5-month baseline observation period, four classes of antimicrobial agents with Gram-negative activity were cycled at 3- to 4-month intervals for 24 months. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the acquisition rate of antimicrobial resistance among Enterobacteriaceae and Pseudomonas aeruginosa obtained from rectal swab cultures performed on admission, weekly during the patients' stay, and at discharge. Rates and microbiology of nosocomial bloodstream infections and ventilator-associated pneumonia were also compared between baseline and cycling periods. The cycling program resulted in a significant change in prescribing practices; the predominant agent used changed with each cycle. Among study patients who were not already colonized with a resistant organism, the rate of acquisition of enteric colonization with bacteria resistant to any of the target drugs remained stable during the cycling period for P. aeruginosa (relative rate, 0.96; 95% confidence Interval, 0.47-2.16) and Enterobacteriaceae (relative rate, 1.57; 95% confidence interval, 0.80-3.43). Hospital-wide, P. aeruginosa from routine clinical cultures resistant to the target drugs increased during the cycling period. The proportion of Gram-negative bacteria isolated from cases of nosocomial bloodstream infection (29% baseline vs. 26% cycling; p = .11) and ventilator-associated pneumonia (80% vs. 41%; p = .06) did not significantly differ. CONCLUSIONS: In this study, antimicrobial cycling did not result in a significant change in enteric acquisition of resistant Gram-negative bacteria among intensive care unit patients.

As a measure for the prevention and control of nosocomial infections in medical school students, we examined the students' titers of antibodies to measles, rubella, varicella, and mumps viruses to determine whether vaccination was required. We also analyzed and discussed correlations among antibody titers to the viruses. Subjects were 363 Juntendo University students, ranging from freshmen to seniors. EIA was used to measure IgG antibody titers. Eight subjects (2.2%) had negative titers for measles, 36 (9.9%) for rubella, 8 (2.2%) for varicella, and 10 (2.7%) for mumps. Seronegative subjects were vaccinated against each virus and high seroconversion rates were obtained: 100% for measles and rubella, 67% for varicella, and 89% for mumps. In addition, we used Pearson's test to search for correlations among the antibody titers for each virus. A weak correlation was observed among antibody titers for measles, rubella, and mumps but not for varicella. These results suggest that MMR vaccine might be effective in people with low levels of antibody to measles, rubella, and mumps.

Pajkos A, Vickery K, Cossart Y. Is biofilm accumulation on endoscope tubing a contributor to the failure of cleaning and decontamination? J Hosp Infect. 2004 Nov; 58(3):224-9.

Department of Infectious Diseases and Immunology, University of Sydney and The Australian Centre for Hepatitis Virology, Sydney, NSW 2006, Australia.

We predicted that biofilm would form on surfaces of endoscope tubing in contact with fluids, and may be difficult to remove by current washing procedures. Its presence may protect micro-organisms from disinfectant action and contribute to failure of decontamination prior to re-use. Tubing samples removed from 13 endoscopes that had been sent to an endoscope-servicing centre were examined for the presence of biofilm and bacteria by scanning electron microscopy. Biological deposits were present on all samples tested. Biofilm (bacteria plus exopolysaccharides matrix) was present on the suction/biopsy channels of five of 13 instruments, and was very extensive on one of these. Bacteria and microcolonies were often but not necessarily associated with surface defects on the tubing. All 12 air/water channels examined showed biofilm, and this was extensive on nine samples. Routine cleaning procedures do not remove biofilm reliably from endoscope channels, and this may explain the unexpected failure of decontamination encountered in practice despite good adherence to infection control guidelines.

Hall J, Hodgson G, Kerr KG. Provision of safe potable water for immuno- compromised patients in hospital. J Hosp Infect. 2004 Oct; 58(2):155-8.

Department of Infection Control, Leeds Teaching Hospitals Trust, Leeds, UK.

We conducted a survey of hospital drinking water provision for patients with immunocompromising conditions in 15 Trusts in the north of England. Ten trusts replied, reporting on provision of drinking water in 14 separate units. Of these, nine provided only tap water to all patients, irrespective of underlying condition. In two units, iced water, with ice from commercially available makers, was used. Five units distinguished between neutropenic and non-neutropenic patients, with the former group receiving cooled, boiled water (three units), sterile water and sterile water or carbonated water (one unit each). No unit provided filtered water. Water in jugs was changed daily, twice daily or only when empty in seven, three and four units, respectively. On 10 units, patients were allowed to provide their own drinking water, but no unit provided written advice to patients on potable water. A survey within our own Trust revealed similar inter-unit disparity. The options for potable water provision were reviewed, taking into account: microbiological quality, organoleptic (perceived taste/smell) acceptability, cost and factors relating to staff safety and patient confidentiality [as it was possible for human immunodeficiency virus (HIV) seropositive patients on some wards to be identified because they were provided with cooled, boiled water]. It concluded that end-line commercially available water filters were the optimal way to provide drinking water to immunocompromised patients in hospital.

A new alcohol-based hand antiseptic (Octoxy hand rub) containing a synergistic combination of an emollient (Octoxyglycerine) and preservatives was developed and evaluated for immediate and prolonged activity against transient bacteria. The in vitro and in vivo antimicrobial efficacy was compared with other alcohol hand rubs containing preservative/antimicrobial (Prevacare and Avagard). In vitro evaluation was carried out using a tube-dilution method and a pig-skin model. Rapid and prolonged efficacy in vivo was evaluated against Staphylococcus epidermidis on the hands of volunteers. Octoxy hand rub was 100% effective in rapidly killing pathogens including methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecium in vitro. In volunteers, all three hand rubs gave a significant reduction in microbial count within 15s. Octoxy hand rub showed significantly higher efficacy against S. aureus and Escherichia coli than Avagard and Prevacare 15 min after application to the pig-skin model, and against S. epidermidis in both the pig-skin model and in volunteers. Use of Octoxy hand rub with broad-spectrum immediate and prolonged antimicrobial activity may be a very effective way of improving hand hygiene without exposing the hands to higher concentrations of antimicrobials.

Department of Microbiology, All India Institute of Medical Sciences, New Delhi.

Dengue, an important human arboviral infection, is endemic in many parts of India. Outbreaks are now reported quite frequently from different parts of the country. We report here findings of serological investigation of serum samples received during a recent outbreak of dengue infection in Delhi from September to November 2003. Acute phase serum samples from suspected cases of dengue infection (including dengue fever, dengue haemorrhagic fever and dengue shock syndrome) of duration 5 days, were tested for dengue specific IgM antibodies by enzyme linked immuno sorbant assay (ELISA). Of the 874 serum samples tested, 456 (52.3% ) were positive for dengue specific IgM antibodies. The maximum number of positive cases was reported in October, peaking in second and third week. Patients in the age group of 21-30 yr accounted for 34.2 per cent of positive cases. This outbreak was less severe as compared to the previous 1996 outbreak and showed a shift towards an older age group.

This review gives an overview of hand hygiene in healthcare and in the community, including some aspects which have attracted little attention, such as hand drying and cultural issues determining hand hygiene behaviour. Hand hygiene is the most effective measure for interrupting the transmission of microorganisms which cause infection both in the community and in the healthcare setting. Using hand hygiene as a sole measure to reduce infection is unlikely to be successful when other factors in infection control, such as environmental hygiene, crowding, staffing levels and education are inadequate. Hand hygiene must be part of an integrated approach to infection control. Compliance with hand hygiene recommendations is poor worldwide. While the techniques involved in hand hygiene are simple, the complex interdependence of factors which determine hand hygiene behaviour makes the study of hand hygiene complex. It is now recognised that improving compliance with hand hygiene recommendations depends on altering human behaviour. Input from behavioural and social sciences is essential when designing studies to investigate compliance. Interventions to increase compliance with hand hygiene practices must be appropriate for different cultural and social needs. New strategies to promote hand hygiene worldwide include the formation of public-private partnerships.

Handwashing is widely accepted as the cornerstone of infection control in the intensive care unit. Nosocomial infections are frequently viewed as an indicator of poor compliance of handwashing. The aim of this review is to evaluate the effectiveness of handwashing on infection rates in the intensive care unit, and to analyse the failure of handwashing. A literature search identified nine studies that evaluated the impact of handwashing or hand hygiene on infection rates, and demonstrated a low level of evidence for the efforts to control infection with handwashing. Poor compliance cannot be blamed as the only reason for the failure of handwashing to control infection. Handwashing on its own does not abolish, but only reduces transmission, as it is dependent on the bacterial load on the hand of healthcare workers. Finally, recent studies, using surveillance cultures of throat and rectum, have shown that, under ideal circumstances, handwashing can only influence 40% of all intensive care unit infections. A randomised clinical trial with the intensive care as randomisation unit is required to support handwashing as the cornerstone of infection control.

We compared the effectiveness of a single dose and a three-day course of antibiotic prophylaxis in preventing bacterial infections in high-risk neonates. The study was a prospective, randomized controlled trial conducted in a 20-bed tertiary referral neonatal intensive care unit (NICU). A series of 130 neonates admitted consecutively to the NICU, fulfilling risk factors for infection, were assigned at random to receive intravenous antibiotic prophylaxis with ampicillin and netilmicin either in two daily doses for 72 h (three-day-administration group, 67 infants) or in a single bolus injection on admission (bolus group, 63 infants). Hospital-acquired infection, the main outcome measure, was defined as infection that developed at least 48 h after admission, and vertical infection (maternally transmitted) was considered to be present when clinical symptoms and abnormal laboratory findings became evident within 48 h of birth. Infections were considered as suspected when clinical and laboratory findings of infection were present, without positive cultures, and as confirmed when positive cultures were also present. No significant differences were found between the two groups of neonates studied in mean birth weight, gestational age or postnatal age on admission. The incidence of vertical infection was similar in the two groups (16/67, 23.9% vs. 14/63, 22.2%). Of the 130 newborns studied, 29 (22.3%) acquired at least one nosocomial infection during their NICU stay; total hospital-acquired infections, calculated as the incidence density of infection (the number of infective episodes divided by the number of days in the NICU), were less frequent among newborns who received the three-day course than the bolus (relative risk 0.69). This difference, although not statistically significant, depended on the different incidence density of confirmed nosocomial infections rather than on suspected infections (relative risk 0.59; 95% confidence interval 0.32-1.09; P=0.1). There were no significant differences between the two groups in overall mortality. A single bolus administration on admission is therefore likely to be as effective as a three-day course of antibiotic prophylaxis in preventing bacterial infection in high-risk infants admitted to an NICU.

The fact that there is a relationship between the standards of aseptic technique performance and the rise in hospital infection rates has been suggested by the Department of Heath's (DoH's, 2004) 'Winning Ways' document. This literature review considers how the aseptic technique is performed in the UK, and examines the nature of ritualistic and evidence-based practice underpinning this skill-based procedure. The findings have identified an emerging glove culture and continuing poor hand-hygiene practices. The alternative 'clean technique' is also adopted widely in clinical practice which confuses the aseptic theory-practice gap. While it is hard to pinpoint an actual time or event that causes infection, it is unlikely nurses will ever become involved in litigation as a result of a poorly performed aseptic technique. However, the review concludes that nurses should not become too complacent. It briefly considers how performance of the aseptic technique can be improved, through creative educational strategy, applied risk assessment and clinical audits of nurses' practices.
