Infection Control Measures

Abstract Nosocomially acquired completely resistant Acinetobacter baumannii strains are a major clinical concern. We identified completely resistant A. baumannii in 6 (4.9%) of 122 A. baumannii isolates in a retrospective chart review at two teaching hospitals. All of these patients had received broad-spectrum antibiotics and had severe underlying comorbid illnesses, long hospitalizations, or recent surgical procedures; 3 had been in the intensive care unit. Five (83%) of the 6 patients were older than 70 years. Only one death occurred. Strict infection control measures may limit further spread.

Exogenous Origin

Background.In 1998, a study in the intensive care unit (ICU) of our institution suggested possible transmission of Pseudomonas aeruginosa from faucet to patient and from patient to patient. Infection-control measures were implemented to reduce the degree ofP. aeruginosacolonization in faucets, to reduce the use of faucet water in certain patient care procedures, and to reduce the rate of transmission from patient to patient.Objective.To evaluate the effect of the control measures instituted in 1999 to preventP. aeruginosainfection and colonization in ICU patients.Design.Prospective, molecular, epidemiological investigation.Setting.A 870-bed, university-affiliated, tertiary care teaching hospital.Methods.The investigation was performed in a manner identical to the 1998 investigation. ICU patients with a clinical specimen positive forP. aeruginosawere identified prospectively. Swab specimens from the inner part of the ICU faucets were obtained for the culture on 9 occasions between September 1997 and December 2000. All patients and environmental isolates were typed by pulsed-field gel electrophoresis (PFGE).Results.Compared with the 1998 study, in 2000 we found that the annual incidence of ICU patients colonized or infected withP. aeruginosahad decreased by half (26.6 patients per 1,000 admissions in 2000 vs 59.0 patients per 1,000 admissions in 1998), although the populations of patients were comparable. This decrease was the result of the decreased incidence of cases in which an isolate had a PFGE pattern identical to that of an isolate from a faucet (7.0 cases per 1,000 admissions in 2000, vs 23.6 per 1,000 admissions in 1998) or from another patient (6.5 cases per 1,000 admissions in 2000 vs 16.5 cases per 1,000 admissions in 1998), whereas the incidence of cases in which the isolate had a unique PFGE pattern remained nearly unchanged (13.1 cases per 1,000 admissions in 2000 vs 15.6 cases per 1,000 admissions in 1998).Conclusions.These results suggest that infection control measures were effective in decreasing the rate ofP. aeruginosacolonization and infection in ICU patients, confirming thatP. aeruginosastrains were of exogenous origin in a substantial proportion of patients during the preintervention period.

High Standards

The intensive care unit (ICU) creates the unique situation of subjecting highly susceptible patients to a variety of invasive procedures that are concentrated in a small unit. Effectively providing life-saving care is considered more important than other measures, such as infection control. Nevertheless, it is frustrating to lose a patient due to a sepsis that could have been prevented by simple hygienic arrangements, the application of aseptic techniques, and infection control measures. There is some confusion about the necessity and efficacy of many of these prescriptions, and some of them must certainly be considered rituals: only controlled studies demonstrating the influence of the specific measure on the infection rate will give a decisive answer about usefulness. Most factors determining the occurrence and transmission of infections lie with the patient's resistance and treatment, but technical, diagnostic, and curative measures may also influence the infection rate. Facilities, techniques followed, and prescribed procedures may differ from hospital to hospital. If we want to draw a conclusion from the comparison of infection rates in different ICUs, it is desirable to compare not only the different preventive measures in nursing procedures and techniques, but also the organization and structure of the units. Therefore, our committee decided to study the hygienic situation of ICUs before elaborating a practicable and valuable system for the registration of nosocomial infections. The study was not limited to the small group of interested teaching hospitals with high standards, but rather, was extended to all Austrian (A) ICUs and a significative sample of German (D) and Belgian (B) ICUs.

Safety Initiative

This case focuses on reducing catheter-related bloodstream infections in the intensive care unit (ICU) by asking the question: Can rates of catheter-related bloodstream infections be reduced by implementing a safety initiative involving five simple infection-control measures by ICU staff? Implementation of a safety initiative involving five simple infection-control measures by ICU staff was associated with a substantial reduction in catheter-related bloodstream infections. While it is not certain that the safety initiative—rather than other factors—was responsible for the observed reduction, the study provides strong evidence that this safety initiative should be implemented widely.

Surveillance Cultures

Objective.To investigate the mode of transmission of and assess control measures for an outbreak of carbapenem-resistant (multidrug-resistant) Acinetobacter baumannii infection involving 6 premature infants.Design.An outbreak investigation based on medical record review was performed for each neonate during the outbreak (from November 2008 through January 2009) in conjunction with an infection control investigation.Setting.A 36-bed, level 3 neonatal intensive care unit in a university-affiliated teaching hospital in Detroit, Michigan.Interventions.Specimens were obtained for surveillance cultures from all infants in the unit. In addition, geographic cohorting of affected infants and their nursing staff, contact isolation, re-emphasis of adherence to infection control practices, environmental cleaning, and use of educational modules were implemented to control the outbreak.Results.Six infants (age, 10-197 days) with multidrug-resistant A. baumannii infection were identified. All 6 infants were premature (gestational age, 23-30 weeks) and had extremely low birth weights (birth weight, 1000 g or less). Conditions included conjunctivitis (2 infants), pneumonia (4 infants), and bacteremia (1 infant). One infant died of causes not attributed to infection with the organism; the remaining 5 infants were discharged home. All surveillance cultures of unaffected infants yielded negative results.Conclusions.The spread of multidrug-resistant A. baumannii infection was suspected to be due to staff members who spread the pathogen through close contact with infants. Clinical staff recognition of the importance of multidrug-resistant A. baumannii recovery from neonatal intensive care unit patients, geographic cohorting of infected patients, enhanced infection control practices, and staff education resulted in control of the spread of the organism.

The Impact

ObjectiveWe describe the efficacy of enhanced infection control measures, including those recommended in the Centers for Disease Control and Prevention’s 2012 carbapenem-resistant Enterobacteriaceae (CRE) toolkit, to control concurrent outbreaks of carbapenemase-producing Enterobacteriaceae (CPE) and extensively drug-resistantAcinetobacter baumannii(XDR-AB).DesignBefore-after intervention study.SettingFifteen-bed surgical trauma intensive care unit (ICU).MethodsWe investigated the impact of enhanced infection control measures in response to clusters of CPE and XDR-AB infections in an ICU from April 2009 to March 2010. Polymerase chain reaction was used to detect the presence ofblaKPCand resistance plasmids in CRE. Pulsed-field gel electrophoresis was performed to assess XDR-AB clonality. Enhanced infection-control measures were implemented in response to ongoing transmission of CPE and a new outbreak of XDR-AB. Efficacy was evaluated by comparing the incidence rate (IR) of CPE and XDR-AB before and after the implementation of these measures.ResultsThe IR of CPE for the 12 months before the implementation of enhanced measures was 7.77 cases per 1,000 patient-days, whereas the IR of XDR-AB for the 3 months before implementation was 6.79 cases per 1,000 patient-days. All examined CPE shared endemicblaKPCresistance plasmids, and 6 of the 7 XDR-AB isolates were clonal. Following institution of enhanced infection control measures, the CPE IR decreased to 1.22 cases per 1,000 patient-days (P= .001), and no more cases of XDR-AB were identified.ConclusionsUse of infection control measures described in the Centers for Disease Control and Prevention’s 2012 CRE toolkit was associated with a reduction in the IR of CPE and an interruption in XDR-AB transmission.
