Characteristics of hospitals and infection control professionals participating in the National Nosocomial Infections Surveillance System 1999.

The National Nosocomial Infections Surveillance (NNIS) system is the oldest and largest monitoring system for health care-acquired infections in the United States. This report describes both the characteristics of NNIS hospitals compared with those of US hospitals with 100 beds or more and their infection control programs. Overall, NNIS hospitals tend to have more hospital beds than the average for-comparable US hospitals. The majority of NNIS hospitals have affiliations with academic medical centers, and most have substantial intensive care units. Even though infection control professionals in NNIS hospitals spend most of their time in inpatient settings, 40% of their time is also spent in a variety of other settings, including home health, outpatient surgery or clinics, extended care facilities, employee health and quality management, and other clinical or administrative activities. As described in this report, the infrastructure of the NNIS system offers a national resource on which to build improved voluntary patient safety monitoring efforts, as outlined in the recent Institute of Medicine report on medical errors.

Searching the health care literature efficiently: from clinical decision-making to continuing education.

Searching the health care literature is an activity in which infection control professionals must routinely engage to seek evidence-based answers to specific practice questions and to stay abreast of developments in the field. Without the appropriate tools, the tremendous volume of clinical literature makes both of these daunting tasks. In this article, we illustrate techniques for searching MEDLINE efficiently, both as a means of answering particular clinical questions and for generating periodic updates on topics of general interest. With use of a specific example relevant to infection control, we demonstrate the identification of appropriate Medical Subject Headings terms that capture a given question or topic and the development of effective searches with use of these terms. We also touch on the advantages of targeting systematic reviews and meta-analyses in searching for evidence and staying abreast of the literature in general.

Practice analysis for infection control and epidemiology in the new millennium.

BACKGROUND: The Certification Board of Infection Control and Epidemiology appointed an advisory committee to conduct a practice analysis (PA) of infection control professionals (ICPs) to identify current practices of ICPs. Results of the PA would assist in the development of a revised certification examination. METHODS: Five thousand seven hundred fifty-three questionnaires were distributed to ICPs in the United States and in Canada, as well as to a subsample of ICPs in other countries. Decision rules and criteria were applied to each identified task in the PA. RESULTS: A total of 1306 responses were available for analysis, for a 24% return rate. The majority of the respondents were certified in infection control, had a background as a registered nurse, and worked in a community hospital with 200 or fewer beds. Six major categories, with 135 tasks, were identified in the PA. The following 2 new categories were included: education and research and infection control aspects of employee health. CONCLUSIONS: The PA reflects current changes in the practice of infection prevention/control and applied epidemiology in the United States and Canada. The test specifications accepted for adoption by the Certification Board of Infection Control and Epidemiology will be used to build all examination forms for a certification program for ICPs.

Staffing requirements for infection control programs in US health care facilities: Delphi project.

BACKGROUND: The guideline for staffing infection control programs of 1 infection control professional (ICP) for every 250 occupied acute care beds has been used in many health care facilities in the United States since 1985. Since that time, the health care system, patient populations, and expectations about the work of infection prevention and control programs have changed substantially. METHODS: The Delphi method was used; data were obtained from a group of ICPs through a series of 10 surveys. Through this iterative process, participant responses were progressively synthesized and areas of agreement and disagreement identified. These surveys were conducted by electronic and paper mail to identify the personal ICP characteristics and structural variables associated with performance of activities required for contemporary infection prevention and control programs in a variety of health care settings. RESULTS: Delphi panel members (n = 32) from 20 states and who represented acute care, long-term care, and community care settings reported tasks in addition to those identified in earlier task analyses as well as expanded responsibilities. Competing responsibilities and lack of adequate resources were the most frequently cited reasons for nonperformance of essential infection control tasks. A ratio of 0.8 to 1.0 ICP for every 100 occupied acute care beds was suggested as adequate staffing by the Delphi panel. CONCLUSIONS: Infection control responsibilities have expanded beyond the traditional acute care setting. Recommendations for staffing must not only consider the number of occupied beds (average daily census) but also include the scope of the program, the complexity of the health care facility or system, the characteristics of the patient population, and the unique or urgent needs of the facility and community.

Influence of an infectious disease consulting service on quality and costs of antibiotic prescriptions in a university hospital.

An infectious disease consulting service was set up at a large tertiary university hospital in 1996 to evaluate and to improve antibiotic prescription patterns. Treatment guidelines for the most common bacterial infections were implemented. On daily ward rounds antibiotic therapies without evidence of an infectious disease were stopped and inappropriate regimens were changed by an infectious disease specialist. During a 6-month prospective intervention period, 3,528 patients were studied on 13 wards of the department of internal medicine; 513 of these patients (14.5%) received antibiotic therapy. These treatment courses were evaluated as adequate in 394 cases (76.8%) and incorrect in 119 cases (23.2%). Inadequate antibiotic substances were chosen in 72 out of 119 cases (60.5%) and there was no indication for treatment in 38 out of 119 cases (32%). Pathogen-specific therapies were inadequate significantly more often than empirical antimicrobial therapies (p < 0.001). In addition, the duration of the perioperative prophylaxis could be limited to 1 d. Comparing the intervention period with a 3-month control interval without an infectious disease consulting service, a total of 31,510 Euro (including the costs for the infectious disease specialist) could be saved. No increase in infection-related mortality or length of stay was observed. These data show that an infectious disease consulting service optimizes antibiotic usage, and is cost-effective as a result of a significant cost reduction in hospitals, while not interfering with the quality of medical care.

A survey of physician's attitudes regarding management of severe group A streptococcal infections.

Intravenous immunoglobulins (IVIG) use in the management of streptococcal toxic shock syndrome remains highly controversial. To evaluate the current management of severe group A streptococcal infections and the feasibility of a randomized controlled trial comparing immunoglobulins versus placebo for streptococcal toxic shock syndrome and/or necrotizing fasciitis, a 32-question mail and web-based survey of Canadian infectious disease specialists was conducted between December 2003 and February 2004. Overall, 172 respondents (90.5%) recommended immunoglobulins as adjunctive treatment of streptococcal toxic shock compared to 67 (35.3%) for fasciitis without toxic shock and 93 (48.9%) for invasive group A streptococcal infections with hypotension. A considerable proportion of respondents agreed that a randomized clinical trial in streptococcal toxic shock (70.1%, 131/187) and necrotizing fasciitis without toxic shock (88.2%, 162/186) would be ethical. From these, a great majority would be willing to enroll patients in a trial comparing IVIG to placebo for streptococcal toxic shock (125/131, 95.4%) and necrotizing fasciitis without shock (152/162, 93.8%). These initial results clearly demonstrate ambivalence in the utilization of intravenous immunoglobulins (IVIG) in invasive group A streptococcal infections in Canada and emphasize the need for further clinical data on immunoglobulin use in streptococcal toxic shock syndrome. They also demonstrate that, although the majority of physicians recommend immunoglobulins, there is important variability between physician recommendations with regard to the indications of use, dose, and time of administration.

Hospital preparedness for severe acute respiratory syndrome in the United States: views from a national survey of infectious diseases consultants.

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.

Bloodstream infections: a trial of the impact of different methods of reporting positive blood culture results.

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.

Infection control dogma: top 10 suspects.

As infection control evolved into an art and science through the years, many infection control practices have become infection control dogmas (principles, beliefs, ideas, or opinions). In this "Reality Check" session of the 4th Decennial International Conference on Nosocomial and Healthcare-Associated Infections, we assessed participants' perceptions of prevalent infection control dogmas. The majority of participants agreed with all dogmas having evidence of efficacy, except for the dogma on the frequency of changing mechanical-ventilator tubing. In contrast, the majority of participants disagreed with dogmas not having evidence of efficacy, except for the dogma on perineal care, umbilical cord care, and reminder signs for isolation precaution. As for controversial dogmas, many of the responses were almost evenly distributed between "agree" and "disagree." Infection control professionals were knowledgeable about evidence-based infection control practices. However, many of the respondents still believe in some of the non-evidence-based dogmas.

Impact of a program of intensive surveillance and interventions targeting ventilated patients in the reduction of ventilator-associated pneumonia and its cost-effectiveness.

OBJECTIVE: We hypothesized that a program of prospective intensive surveillance for ventilator-associated pneumonia (VAP) and concomitant implementations of multimodal, multidisciplinary preventive and intervention strategies would result in a reduction in the incidence of VAP and would be cost-effective. SETTING: Medical and surgical intensive care units (ICUs) in a university teaching hospital. INTERVENTIONS: All ventilated patients in the medical and surgical ICUs were monitored for VAP from January 1997 through December 1998. Interventions including elevation of the head of the bed, use of sterile water and replacement of stopcocks with enteral valves for nasogastric feeding tubes, and prolongation of changing of in-line suction catheters from 24 hours to as needed were implemented. RESULTS: The rates of VAP decreased by 10.8/1,000 ventilator-days in the medical ICU (CI95, 4.65-16.91) and by 17.2/1,000 ventilator-days in the surgical ICU (CI95, 2.85-31.56) when they were compared for 1997 and 1998. With the use of the estimated cost of a VAP of dollars 4,947 from the literature, the reduction resulted in cost savings of dollars 178,092 and dollars 148,410 in the medical and surgical ICUs, respectively, for a total of dollars 326,482. In addition, dollars 25,497 was saved due to the lengthening of the time for the change of in-line suction catheters, resulting in a cost savings of dollars 351,979. This total cost savings of dollars 351,979 minus the cost of enteral valves of dollars 2,100 resulted in total net savings of dollars 349,899. CONCLUSION: Intensive surveillance and interventions targeted at ventilated patients resulted in reduction of VAP and appeared to be cost-effective.

Alcohol-based handrub: evaluation of technique and microbiological efficacy with international infection control professionals.

BACKGROUND AND OBJECTIVE: The Centers for Disease Control and Prevention has published a new guideline on hand hygiene promoting the use of the alcohol-based handrub, but the technique was not addressed. The goal of this study was to evaluate the influence of technique on the efficacy of the alcohol-based handrub. PARTICIPANTS: Healthcare workers (HCWs) attending a course in hospital epidemiology. METHODS: A fluorescent dye was added to a hand antiseptic, and hands were checked under ultraviolet light after antiseptic cleansing. Data regarding the numbers of predefined fluorescent areas on the skin were collected in addition to demographic data such as age, gender, job description, and job experience. Results of the visualization test were compared with the data from microbiological samples before and after the procedure by the hand plate technique. RESULTS: Sixty HCWs were tested, 63% of whom had worked in infection control for more than 10 years. Sixty-six percent of all participants still had detectable bacteria after antisepsis. The mean log10 CFU reduction was 2.0 (range, 0-3.85). Twenty-five percent of all HCWs achieved less than 1.1 log10 CFU. Staphylococcus aureus was isolated from 13% (one of them being methicillin resistant) and gram-negative bacilli from 6.7%. After using the alcohol handrub, one subject still remained positive for S. aureus. Years of experience was the single most important factor predicting antimicrobial efficacy. CONCLUSIONS: Technique is of crucial importance in hand antisepsis. Major deficiencies were detected among even highly trained HCWs. Training should be provided before switching from handwashing to the alcohol handrub
