Procedures to protect health-care workers from HIV infection: category I (health-care) workers.

At the heart of the recommendations to prevent HIV transmission in workers who perform high-risk tasks are the universal blood and body fluid precautions. These precautions are meant to be followed by all health-care workers in the care of all patients and by public safety workers (e.g., firefighters, police officers, and correctional facility personnel) whenever they perform specific tasks that expose them to blood, body fluids, or tissues. Universal precautions apply to blood, semen, vaginal secretions, body tissues, cerebrospinal fluid, synovial fluid, pleural fluids, peritoneal fluid, pericardial fluid, and amniotic fluid. These fluids have either been implicated in HIV transmission or their risk of transmission is unknown. Other fluids or excretions are excluded from universal precautions because epidemiologic studies have failed to implicate them in HIV transmission. These include feces, nasal secretions, sputum, sweat, tears, urine, vomitus, breast milk, and saliva, unless they contain visible blood. However, routine precautions (handwashing, gloves, etc.) to prevent exposure to other diseases transmitted by these media should be followed. Other precautions are directed at health-care workers who perform specialized at-risk procedures, e.g., surgeons, dentists, laboratory workers, etc. In general, recommendations for these workers include the universal precautions plus additional emphasis on the use of barrier measures. Although the risk of environmentally mediated HIV transmission is negligible, it is theoretically possible, and recommendations to kill or inactivate HIV on environmental surfaces should be followed. Fortunately, HIV is easily inactivated in the environment. The cheapest and most convenient method is a 1:10 or 1:100 dilution of household bleach.(ABSTRACT TRUNCATED AT 250 WORDS)

Design and analysis considerations for combining data from multiple biomarker studies

Pooling data from multiple studies improves estimation of exposure-disease associations through increased sample size. However, biomarker exposure measurements can vary substantially across laboratories and often require calibration to a reference assay prior to pooling. We develop two statistical methods for aggregating biomarker data from multiple studies: the full calibration method and the internalized method. The full calibration method calibrates all biomarker measurements regardless of the availability of reference laboratory measurements while the internalized method calibrates only non-reference laboratory measurements. We compare the performance of these two aggregation methods to two-stage methods. Furthermore, we compare the aggregated and two-stage methods when estimating the calibration curve from controls only or from a random sample of individuals from the study cohort. Our findings include the following: (1) Under random sampling for calibration, exposure effect estimates from the internalized method have a smaller mean squared error than those from the full calibration method. (2) Under the controls-only calibration design, the full calibration method yields effect estimates with the least bias. (3) The two-stage approaches produce average effect estimates that are similar to the full calibration method under a controls only calibration design and the internalized method under a random sample calibration design. We illustrate the methods in an application evaluating the relationship between circulating vitamin D levels and stroke risk in a pooling project of cohort studies.     

A new approach to the isolation of hospitalized patients with infectious diseases: alternative systems

A new guideline developed by the Centers for Disease Control suggests that hospitals adopt one of two alternative isolation systems: the category system or the disease-specific system. The older category system has been modified to reflect current knowledge; for example, the category of protective isolation has been deleted, new categories for contact precautions and tuberculosis precautions have been added, the specific precautions indicated in the other categories have been substantially modified, and many infections have been assigned to new categories. The disease-specific system, a newly developed approach, lists the specific isolation precautions indicated for each infectious disease. Whereas the revised category system offers greater simplicity in practice, the disease-specific system minimizes unnecessary precautions. Both systems allow patient-care personnel more decision-making authority in determining which precautions to apply.     

Impact of selective screening in the emergency department on meticillin-resistant Staphylococcus aureus control programmes

Identification of the meticillin-resistant Staphylococcus aureus (MRSA) reservoir by active screening followed by the implementation of contact precautions is one of the major components of MRSA control programmes. The objective of this study was to evaluate the results of a programme of selective screening in an emergency department (ED) and the appropriateness of the contact precautions implemented. This was estimated by distinguishing necessary and unnecessary days of contact precautions. This estimation was performed for all days of contact precautions and, more specifically, for days of preventive contact precautions implemented before the availability of screening results. During a three-year period, screening of MRSA carriers was performed on 0.95% (N=605) of patients visiting the emergency ward. Among the 193 (31.9%) MRSA carriers identified, 159 were hospitalized in the short-length-hospitalization area (SLHA) of the ED and/or in other wards. Among the 140 patients admitted to the SLHA, 44 were hospitalized for at least 48 h, with a mean length of hospitalization of 5.9 days. The cumulative duration of hospitalization of carriers identified by screening was 1897 days. In total, 2370 days of contact precautions (including 924 days of preventive precautions) were implemented for patients screened in the ED. Considering the whole hospital, the appropriateness of this entire programme of contact precautions for patients screened in the ED was 80.0% (52.1% for the SLHA), whereas the specific appropriateness of preventive isolation days was 48.6% (43.6% for the SLHA). This study underscores the risk of MRSA cross-transmission in the SLHA, and the usefulness of implementing a control programme of screening carriers in the ED.
