RESUMEN
BACKGROUND: Bloodstream infections (BSI) cause significant morbidity and mortality among hospitalized infants. PURPOSE: Reduction of BSIs has emerged as an important patient safety goal. Implementation of central line insertion bundles, standardized line care protocols, and health care provider education programs have reduced BSI in NICUs around the country. The ability of large tertiary care centers to decrease nosocomial infections, including BSI, has been demonstrated. However, long-term BSI reductions in infants are not well documented. We sought to demonstrate that a low incidence of BSI can be maintained over time in a tertiary care NICU. RESULTS: Baseline BSI incidence for infants admitted to the NICU was 5.15 and 6.08 episodes per 1000 infant-days in 2005 and 2006, respectively. After protocol implementation, the incidence of BSI decreased to 2.14/1000 infant-days and 2.44/1000 infant-days in 2008 and 2009, respectively. Yearly incidence remained low over the next 4 years and decreased even further to 0.20 to 0.45 infections per 1000 infant-days. This represents a 92% decrease in BSI over a period of more than 5 years. IMPLICATIONS FOR PRACTICE: Implementation of a nursing-led comprehensive infection control initiative can effectively produce and maintain a reduction in the incidence of BSI in infants at a large tertiary care NICU. IMPLICATIONS FOR RESEARCH: Additional research is needed to effectively expand prevention of central line-associated BSIs to BSIs of all etiologies.

Hospitals continue to struggle with preventable healthcare-associated infections. Whereas the focus is generally on proactive prevention processes, performing retrospective case reviews of infections can identify opportunities for quality improvement and maximize learning from defects. This brief article provides practical information for structuring the case review process using readily available health system platforms. Using a structured approach for case reviews can help identify trends and opportunities for improvement.
RESUMEN
BACKGROUND: After surveillance surveys documented the absence of methicillin-resistant Staphylococcus aureus (MRSA) in our intensive care nursery, an outbreak of MRSA infection occurred there during a 7-month period in 2005. METHODS: Control measures included reinforcement of hand hygiene and contact precautions procedures. Active surveillance cultures were obtained on all neonates, including interinstitutional transfers. A cohort unit was dedicated exclusively for neonates with MRSA. Pulsed-field gel electrophoresis was performed on isolates to determine relatedness. We surveyed transferring hospitals to evaluate MRSA activity and surveillance practices in their nurseries. RESULTS: Twenty-five neonates were colonized with MRSA; 9 of these had clinical infections. Isolates from 18 of 21 neonates from this outbreak and 4 neonates from a previous cluster were identical, including 1 isolate obtained upon transfer from another institution. Admission and discharge logs from a 9-month period showed that 127 of 460 admissions (27.6%) were admitted from 34 hospitals, and 247 of 460 (53.7%) were discharged to 32 hospitals. Among 30 transferring hospitals responding to our survey, MRSA activity occurred in 2 of 28 (7%) level 1 nurseries, 4 of 11 (36%) level 2 nurseries and 6 of 10 (60%) level 3 nurseries. Nine of the 30 hospitals (30%) performed some active surveillance. CONCLUSIONS: Interinstitutional transfer can play a role in the initiation and propagation of MRSA outbreaks in neonatal nurseries. The burden of MRSA in area nurseries and the rate of transfers affect the potential for interhospital spread of MRSA and may justify changes in policy regarding surveillance for MRSA and communication between hospitals.

OBJECTIVE: The Joint Commission, the Centers for Disease Control and Prevention, and the World Health Organization challenge hospitals to achieve and sustain compliance with effective hand hygiene (HH) practice; however, many inpatient units fail to achieve a high level of reliability. The aim of the project was to increase and sustain health care worker (HCW) compliance with HH protocols from 87% (level of reliability [LOR] 1) to ≥95% (LOR 2) within 9 months on 2 pediatric inpatient units in an academic children's hospital. METHODS: This study was a time-series, quality-improvement project. Interventions were tested through multiple plan-do-study-act cycles on 2 pediatric inpatient units. HH compliance audits of HCWs on these units were performed randomly each week by the hospital infection prevention program. Control charts of percentages of HCW HH compliance were constructed with 3-σ (data within 3 SDs from a mean) control limits. These control limits were adjusted after achieving significant improvements in performance over time. Charts were annotated with interventions including (1) increasing awareness, (2) providing timely feedback, (3) empowering patients and families to participate in mitigation, (4) providing focused education, and (5) developing interdisciplinary HH champions. RESULTS: HH compliance rates improved from an average of 87% (LOR 1) to ≥95% (LOR 2) within 9 months, and this improvement has been sustained for >2 years on both pediatric inpatient units. CONCLUSIONS: Significant and sustained gains in HH compliance rates of ≥95% (LOR 2) can be achieved by applying high-reliability human-factor interventions.

We implemented a direct-observer hand hygiene audit program that used trained observers, wireless data entry devices, and an intranet portal. We improved the reliability and utility of the data by standardizing audit processes, regularly retraining auditors, developing an audit guidance tool, and reporting weighted composite hand hygiene compliance scores.

Over a 6-year period, Burkholderia cepacia complex species were isolated from cystic fibrosis (CF) patients receiving care at The University of North Carolina Hospitals (clinic CF patients) and from those referred from other treatment centers. Fifty-six isolates collected from 30 referred patients and 26 clinic CF patients were characterized by pulsed-field gel electrophoresis (PFGE) and were assayed by PCR to detect the cable pilin gene, cblA. PFGE results indicated that six separate clusters (clusters A to F) were present among the 56 isolates and that three clusters (clusters A, B, and E) consisted only of isolates from referred patients infected with B. cepacia complex isolates prior to referral. However, one cluster (cluster C) consisted of isolates from four CF patients, and hospital records indicate that this cluster began with an isolate that came from a referred patient and that spread to three clinic CF patients. Cluster D consisted of two isolates from clinic CF patients, and hospitalization records are consistent with nosocomial, patient-to-patient spread. cblA was present in only 4 of the 56 isolates and included isolates in cluster E from the referred patients. Our results indicate a lack of spread of a previously characterized, transmissible clone from referred patients to our clinic CF population. Only two instances of nosocomial, patient-to-patient spread could be documented over the 6-year period. An additional spread of an isolate (cluster F) from a referred patient to a clinic patient could not be documented as nosocomial and may have been the result of spread in a nonhospitalized setting. The majority (36 of 56) of our B. cepacia complex-infected CF patients harbor isolates with unique genotypes, indicating that a diversity of sources account for infection. These data suggest that CF patients infected with B. cepacia complex and referred for lung transplantation evaluation were not a major source of B. cepacia complex strains that infected our resident CF clinic population.
