False-positive blood culture results may lead to prolonged hospitalization, inappropriate antibiotic administration, and increased healthcare costs. We conducted a review of the literature to assess the effect of skin antiseptic agents on the rate of false-positive blood culture Results. We found no clear evidence to suggest which antiseptic should be used to prevent false-positive Results. Studies suggest, however, a possible benefit from the use of prepackaged skin antiseptic kits and alcohol-containing antiseptics.

A validation study was performed for the intensive care unit component of the German nosocomial infections surveillance system (Krankenhaus Infektions Surveillance System [KISS]). A total of 286 reported infections and 1,195 medical records with no reported infection from 20 randomly selected KISS intensive care units were reviewed by trained physicians. The mean sensitivity was 66% (median, 81%), and the mean specificity was 99.4% (median, 99.6%).

This study reports an investigation of outbreaks of methicillin-resistant Staphylococcus aureus (MRSA) infection and colonization involving 17 newborns in the neonatal unit of a teaching hospital. A neonatal specialist colonized with MRSA that eventually became mupirocin-resistant was implicated as a recurrent source of transmission of MRSA to newborns.

We conducted a cross-sectional survey from October through December 2004 of 8,312 residents of Shiraz, Iran, to investigate Iranians' perceptions about undergoing dental treatment in dental offices where other patients or the dentist and/or dental assistants are infected with human immunodeficiency virus (HIV). Most survey respondents (83%) had acceptable general knowledge about the mode of transmission of HIV and about acquired immunodeficiency syndrome (AIDS); however, many misconceptions were observed. A negative association was detected between the level of concern about contracting HIV/AIDS and the intention to continue treatment in services where patients with HIV/AIDS were also treated or where the dentist and/or dental assistants had HIV/AIDS.

Registered nurses working at a teaching hospital in Kuwait were surveyed to assess the psychosocial variables associated with their intention to comply with glove-wearing recommendations. Perceived consequences and normative beliefs, as well as sex and years of nursing experience, significantly influenced their behavioral intentions, suggesting that improvements in intention to comply are more likely to come from practical demonstrations that show nurses the potential outcomes of both using and not using gloves.

Hands and instruments used by healthcare workers may serve as vectors for the nosocomial transmission of microorganisms. The use of cellular telephones by medical personnel and the associated nosocomial transmission of pathogens have not been thoroughly examined. Findings from our study show that cellular telephones are commonly used by hospital personnel, even during patient contact. One-fifth of the cellular telephones examined in this study were found to harbor pathogenic microorganisms, showing that these devices may serve as vectors for transmission to patients.

Using 33 dogmatic statements about infection control, we assessed the knowledge of infection control nurses at a conference in Iran and compared their responses with those of infection control nurses at a conference in the United States. A majority of those at the Iran conference responded correctly to 11 (33%) of 33 statements, whereas a majority at the US conference responded correctly to 20 (61%) of the statements. The differences in responses were significant (P < .001). Nurses at the Iran conference were more likely to agree with dogma not supported by the literature and to put more faith in general cleanliness to prevent infection than is supported by the literature. A similar questionnaire survey might be useful in countries like Iran that are developing their infection control personnel and infrastructure.

We investigated the epidemiology and prevention of sharps injuries in the United Arab Emirates. Among 82 emergency nurses and 38 doctors who responded to our questionnaire, risk factors for sharp device injuries identified using the Haddon matrix included personal factors (for the pre-event phase, a lack of infection control training, a lack of immunization, and recapping needles, and for the postevent phase, underreporting of sharps injuries) and equipment-related factors (for the pre-event phase, failure to use safe devices; for the event phase, failure to use gloves in all appropriate situations). Nearly all injuries to doctors were caused by suture needles, and among nurses more than 50% of injuries were caused by hollow-bore needles.

We calculated the incidence of nosocomial infection in 2 intensive care units (ICUs) on the basis of prevalence data recorded from 1997 through 2002 and compared these estimates to cumulative incidences measured in the 2 ICUs during the same period to investigate the feasibility and the reliability of converting prevalence data to incidence estimates. Decreases in the calculated and measured incidences over time in the ICUs were found to be statistically significantly related.
