Pro/con clinical debate: isolation precautions for all intensive care unit patients with methicillin-resistant Staphylococcus aureus colonization are essential.
(1/19)
Antibiotic-resistant bacteria are an increasingly common problem in intensive care units (ICUs), and they are capable of impacting on patient outcome, the ICU's budget and bed availability. This issue, coupled with recent outbreaks of illnesses that pose a direct risk to ICU staff (such as SARS [severe acute respiratory syndrome]), has led to renewed emphasis on infection control measures and practitioners in the ICU. Infection control measures frequently cause clinicians to practice in a more time consuming way. As a result it is not surprising that ensuring compliance with these measures is not always easy, particularly when their benefit is not immediately obvious. In this issue of Critical Care, two experts face off over the need to isolate patients infected with methicillin-resistant Staphylococcus aureus. (+info)
Hospital preparedness for severe acute respiratory syndrome in the United States: views from a national survey of infectious diseases consultants.
(2/19)
In this survey of infectious diseases consultants, 90% reported that their health care facilities have plans in place to address severe acute respiratory syndrome (SARS). Some plan elements exceed current recommendations, whereas others are less stringent. Resource issues associated with airborne isolation and respirators were reported. Sixty-one percent of the respondents expressed some concern about their facility's preparation and capacity for managing patients with SARS. Recent draft guidance on SARS preparedness from the Centers for Disease Control and Prevention may help address some of these issues. (+info)
Bloodstream infections: a trial of the impact of different methods of reporting positive blood culture results.
(3/19)
BACKGROUND: The impact of how positive blood culture results are reported on the evolution bloodstream infections (BSIs) has not been assessed. METHODS: We randomly assigned patients with BSIs into 3 groups: group A (for which physicians received a conventional report), group B (for which physicians received a conventional report and a written alert on the chart with clinical advice), and group C (for which physicians received the above plus oral clinical advice). The adequacy of therapy before and after receipt of the different types of information was assessed. RESULTS: Overall, 297 episodes (109 in group A, 99 in group B, and 89 in group C) were studied. Patients who received inadequate treatment before receiving microbiological information had a longer mean (+/-SD) hospital stay (27.2+/-32.4 vs. 19.4+/-15.8 days; P=.017), a higher mean risk of Clostridium difficile-associated diarrhea (8.3% vs. 1.9%; P=.013), a higher mean overall mortality rate (30.8% vs. 19.4%; P=.025), and a higher mean risk of infection-related mortality (23.3% vs. 13.6%; P=.031). After receipt of microbiological reports, recommendations for changes in therapy were issued for patients in groups B (52.3%) and C (53.1%). For groups A, B, and C, the proportions of days on which adequate treatment was received were 66.3%, 92.1%, and 91.2% (P<.001); the mean numbers of defined daily doses of appropriate antibiotic therapy were 16.4, 22.2, and 20.7 (P=.003); the mean durations of hospital stay were 19.8, 23.6, and 24.1 days (P=.761); and the mortality rates during the late period were 12.9%, 15.6%, and 11% (P=.670), respectively. The mean costs of antimicrobials per episode in groups A, B, and C were 580.63, 537.98, and 434.53 (US707.85 dollars, US699.73 dollars, and US529.73 dollars, respectively). CONCLUSIONS: Written- or oral-alert reports with clinical advice should complement traditional microbiological reports for patients with BSIs. (+info)
Physician and infection control practitioner HIV/AIDS reporting characteristics.
(4/19)
We surveyed a random sample of South Carolina physicians and infection control practitioners about the reporting of human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) cases. Of physicians surveyed, 79% indicated that HIV infection as well as AIDS should be reported by name. The following characteristics were associated with those physicians who do not report AIDS cases: not feeling responsible for reporting, not reporting a case perceived to have been reported in another state, believing that information required for reporting is not on the chart, and residing in an urban setting. Targeted education can address these underreporting factors. (+info)
Reduced risk of surgical site infections through surveillance in a network.
(5/19)
OBJECTIVE: To estimate the effect of multicentre surveillance for nosocomial infections on patients' risk of surgical site infection (SSI). DESIGN: Prospective multi-centre cohort study, from January 1996 to December 2000. SETTING: Acute care hospitals in The Netherlands. STUDY PARTICIPANTS: All 50 hospitals performing surveillance for one of seven selected procedures in the Dutch surveillance network for nosocomial infections PREZIES were invited. Thirty-seven hospitals participated (74%) and provided information on 21 920 operations, after which 885 (4%) SSI occurred. INTERVENTIONS: The surveillance comprised the following: Development of surveillance methodology by multidisciplinary team; use of a standardized registration protocol and software; regular training of data collectors; anonymous inter-hospital comparison of infection rates and feedback of results; appointment of one contact person per hospital, responsible for data collection; and dissemination of results to other health care professionals. Regular discussion of both successful and failing prevention strategies that had been instituted based on the surveillance results. OUTCOME MEASURE: Risk of SSI. RESULTS: The risk of infection was reduced for patients who had an operation during the fourth surveillance year (RR = 0.69; 95% confidence interval (CI) = 0.52-0.89) and decreased further for patients operated on during the fifth surveillance year (RR = 0.43; CI = 0.24-0.76) as compared with patients who underwent surgery within one year of the start of surveillance in their hospital. No significant risk reduction was observed for patients operated on during the second and third surveillance years. CONCLUSION: Surveillance, supported by participation in a surveillance network, reduced the risk of SSI in surgical patients registered in the Dutch surveillance network PREZIES. Our results suggest that infection control teams need to be perseverant and that surveillance programmes should be given time before evaluation. (+info)
Management of persistent bacteremia caused by methicillin-resistant Staphylococcus aureus: a survey of infectious diseases consultants.
(6/19)
We conducted a survey in 2005 of infectious diseases consultants and asked about persistent bacteremia due to methicillin-resistant Staphylococcus aureus. Many consultants perceived an increase in the frequency of illness, and, when presented with vancomycin minimum inhibitory concentrations approaching the limit of the susceptible range, most consultants indicated that they would switch to newer antimicrobial agents for treatment.

Infections in hospitalized patients: what is happening and who can help?
(7/19)
The continuing emergence of multidrug-resistant bacteria calls for new approaches to the management and treatment of infections in hospitalized patients. Health care-associated infections cause substantial morbidity and mortality while driving up health care resource use and costs worldwide. The continued spread of antimicrobial resistance requires a multidisciplinary approach and closer collaboration among health care providers, especially hospitalists, pharmacists, infection control practitioners, and infectious disease specialists. Such collaboration can potentially reduce treatment failures and minimize the spread of multidrug-resistant organisms between health care settings and the community. (+info)
From a pump handle to oral rehydration therapy: a model of translational research.
(8/19)
Few afflictions have attracted as much attention and impacted on as many societal and biomedical areas as cholera. Dr. John Snow's studies launched the field of epidemiology, were early applications of medical cartography, and promoted the use of statistical methods in medicine. The finding that cholera was due to the ingestion of contaminated water lent to the demise of the prevalent "miasmatic theory of contagion," set the platform for the "germ theory of disease," and promoted the growth of public health concerns for water purification and sanitation. More recent attention to this disease led to the notion of "secretory diarrhea" and the translation of basic principles to the development of oral rehydration therapy and its "spin-offs" (Gatorade and Pedilyte).
