Is Compliance with Hand Disinfection in the Intensive Care Unit Related to Work Experience?

Electronic monitoring in combination with direct observation as a means to significantly improve hand hygiene compliance

Monitoring hand hygiene compliance among health care personnel (HCP) is an essential element of hand hygiene promotion programs. Observation by trained auditors is considered the gold standard method for establishing hand hygiene compliance rates. Advantages of observational surveys include the unique ability to establish compliance with all of the World Health Organization "My 5 Moments for Hand Hygiene" initiative Moments and to provide just-in-time coaching. Disadvantages include the resources required for observational surveys, insufficient sample sizes, and nonstandardized methods of conducting observations. Electronic and camera-based systems can monitor hand hygiene performance on all work shifts without a Hawthorne effect and provide significantly more data regarding hand hygiene performance. Disadvantages include the cost of installation, variable accuracy in estimating compliance rates, issues related to acceptance by HCP, insufficient data regarding their cost-effectiveness and influence on health care-related infection rates, and the ability of most systems to monitor only surrogates for Moments 1, 4, and 5. Increasing evidence suggests that monitoring only Moments 1, 4, and 5 provides reasonable estimates of compliance with all 5 Moments. With continued improvement of electronic monitoring systems, combining electronic monitoring with observational methods may provide the best information as part of a multimodal strategy to improve and sustain hand hygiene compliance rates among HCP.

Point-of-care hand hygiene: preventing infection behind the curtain

Best practices for hand hygiene provide indications for performance of hand hygiene at specific points in time during patient care. For hand hygiene to prevent infections, hand hygiene resources must be readily available to health care workers whenever required. This article reviews practices and recommendations intended to facilitate hand hygiene behavior at the point of care (POC) within the health care setting. Key aspects of POC hand hygiene include the provision of alcohol-based hand rub products, integration of dispensing solutions within the patient zone, consideration of patient care workflow, and dispenser designs that optimize acceptance and usage.

Observation-based evaluation of hand hygiene practices and the effects of an intervention at a public hospital cafeteria

BACKGROUND

Hand hygiene is important before meals, especially in a hospital cafeteria where patrons may have had recent contact with infectious agents. Few interventions to improve hand hygiene have had measureable success. This study was designed to use a poster intervention to encourage hand hygiene among health care workers (HCWs) and hospital visitors (HVs) upon entry to a hospital cafeteria.

METHODS

Over a 5-week period, a poster intervention with an accessible hand sanitizer unit was deployed to improve hand hygiene in a hospital cafeteria. The dependent variable observed was hand hygiene attempts. Study phases included a baseline, intervention, and follow-up phase, with each consisting of 3 randomized days of observation for 3 hours during lunch.

RESULTS

During the 27 hours of observation, 5,551 participants were observed, and overall hand hygiene frequency was 4.79%. Hygiene attempts occurred more frequently by HCWs than HVs (P = .0008) and females than males (P = .0281). Hygiene attempts occurred more frequently after poster introduction than baseline (P = .0050), and this improvement was because of an increase in frequency of HV hand hygiene rather than HCW hand hygiene.

CONCLUSION

The poster intervention tool with easily accessible hand sanitizer can improve overall hand hygiene performance in a US hospital cafeteria.

Intensive care unit outbreak of extended-spectrum beta-lactamase-producing Klebsiella pneumoniae controlled by cohorting patients and reinforcing infection control measures

OBJECTIVE

To describe an outbreak of extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae in the intensive care units (ICUs) of a hospital and the impact of routine and reinforced infection control measures on interrupting nosocomial transmission.

DESIGN

Outbreak report.

SETTING

A 31-bed intensive care department (composed of 4 ICUs) in a university hospital in Belgium.

INTERVENTION

After routine infection control measures (based on biweekly surveillance cultures and contact precautions) failed to interrupt a 2-month outbreak of ESBL-producing K. pneumoniae, reinforced infection control measures were implemented. The frequency of surveillance cultures was increased to daily sampling. Colonized patients were moved to a dedicated 6-bed ICU, where they received cohorted care with the support of additional nurses. Two beds were closed to new admissions in the intensive care department. Meetings between the ICU and infection control teams were held every day. Postdischarge disinfection of rooms was enforced. Broad-spectrum antibiotic use was discouraged.

RESULTS

Compared with a baseline rate of 0.44 cases per 1,000 patient-days for nosocomial transmission, the incidence peaked at 11.57 cases per 1,000 patient-days (October and November 2005; rate ratio for peak vs baseline, 25.46). The outbreak involved 30 patients, of whom 9 developed an infection. Bacterial genotyping disclosed that the outbreak was polyclonal, with 1 predominant genotype. Reinforced infection control measures lasted for 50 days. After the implementation of these measures, the incidence fell to 0.08 cases per 1,000 patient-days (rate ratio for after the outbreak vs during the outbreak, 0.11).

CONCLUSION

These data indicate that, in an intensive care department in which routine screening and contact precautions failed to prevent and interrupt an outbreak of ESBL-producing K. pneumoniae, reinforced infection control measures controlled the outbreak without major disruption of medical care.
