We report the incidence of, and risk factors for, ventilator-associated pneumonia (VAP) at the King Fahad National Guard Hospital. Of the 202 patients studied, 41 (25.2%) had VAP The incidence density was 16.8/1,000 person-days of ventilation. Variables significantly associated with VAP were serious injury from motor-vehicle accident, enteral feeding, and length of ventilation. The avoidance of unnecessary enteral nutrition could help to reduce VAP.

Concern frequently is voiced about individuals not complying with guidelines intended to prevent spread of antibiotic-resistant pathogens from patient to patient, but institutional decisions to ignore Centers for Disease Control and Prevention guidelines recommending detection and isolation of colonized patients also have contributed greatly to the increasing rate of infections due to these pathogens. This is so because colonized patients are the main reservoir for spread, and barrier precautions prevent spread much more effectively than Standard Precautions. Providing effective leadership and changing this culture of noncompliance must begin with the infection control team believing that spread is both important and preventable.

The frequency of hepatitis C (HCV), hepatitis B (HBV), human immunodeficiency virus (HIV), and human T-cell lymphotropic virus (HTLV) I/II was determined in the emergency room of a teaching hospital. Of 909 patients, 19% had at least one infection; 7.8% had HCV, 6.9% HBV, 3.3% HIV, and 2.8% HTLV I/II. The probability that a healthcare worker would have an accident with an infected patient and seroconvert was 4.99 to 24.9 per 100,000 venipunctures for HBV, 5.6 to 8.4 for HCV, and 0.12-0.16 for HIV in our emergency room.

A retrospective review of methicillin-resistant Staphylococcus aureus isolates from the Naval Medical Center, San Diego, for the years 1994 through 1997, found that the annual number of community-acquired MRSA isolates increased during the period. These outpatient isolates were more likely than inpatient isolates to be sensitive to a greater number of antibiotics.

A girl developed Plasmodium falciparum malaria in Riyadh, Saudi Arabia, a non-malarious area. Twelve to 18 days before onset, she had been hospitalized for asthma on the same ward as three malaria patients. The only link between the malaria patients and the asthma patient was a multidose heparin container used to fill syringes for use on heparin locks and intravenous devices. Contamination of the heparin with blood occurred on at least one occasion when a needle had been left in place through the septum of this container and was used to refill a used syringe.

The 4th Decennial International Conference on Nosocomial and Healthcare-Associated Infections provided a unique forum to assess opinions regarding current infection control controversies. The “Reality Check” sessions were a special portion of the conference where attendees expressed their opinions on these issues and heard varying viewpoints from noted experts. Using an Audience Response System (ARS), individual audience members cast their votes during seven different sessions. Although systems such as the ARS have been used during other conferences, there are no published accounts to date describing audience viewpoints on infection control topics. An overview of the “Reality Check” sessions follows.

There is intense antimicrobial use in long-term-care facilities (LTCFs), and studies repeatedly document that much of this use is inappropriate. The current crisis in antimicrobial resistance, which encompasses the LTCF, heightens concerns of antimicrobial use. Attempts to improve antimicrobial use in the LTCF are complicated by characteristics of the patient population, limited availability of diagnostic tests, and the virtual absence of relevant clinical trials. This position paper recommends approaches to management of common infections in LTCF patients and proposes minimal standards for an anti-microbial review program. In developing these recommendations, the position paper acknowledges the unique aspects of provision of care in the LTCF.

The extensive use of antibiotics in long-term–care facilities has led to increasing concern about the potential for the development of antibiotic resistance. Relatively little is known, however, about the quantitative relation between antibiotic use and resistance in this population. A better understanding of the underlying factors that account for variance in antibiotic use, unexplained by detected infections, is needed. To optimize antibiotic use, evidence-based standards for empirical antibiotic prescribing need to be developed. Limitations in current diagnostic testing for infection in residents of long-term–care facilities pose a substantial challenge to developing such standards.

A retrospective case-control study compared 40 human immunodeficiency virus (HIV)-infected patients with 43 nosocomial bacteremias (NB) to 77 HIV-infected patients without NB. Presence of a peripheral venous catheter (PVC) was associated with occurrence of NB and was significantly more frequent in NB without an identified source. PVCs probably are an underestimated source of NB in HIV-infected patients.

The results of performing two-step tuberculin skin testing of healthcare workers at a hospital in eastern North Carolina in 1997 and 1998 were reviewed. Of 1,248 new employees, approximately 500 required two-step testing, which identified only 5 new employees who might have been falsely labeled as converters during the subsequent year's surveillance testing.
