Multicenter Intervention Program to Increase Adherence to Hand Hygiene Recommendations and Glove Use and to Reduce the Incidence of Antimicrobial Resistance

Objective.

To determine whether a multimodal intervention could improve adherence to hand hygiene and glove use recommendations and decrease the incidence of antimicrobial resistance in different types of healthcare facilities.

Design.

Prospective, observational study performed from October 1, 1999, through December 31, 2002. We monitored adherence to hand hygiene and glove use recommendations and the incidence of antimicrobial-resistant bacteria among isolates from clinical cultures. We evaluated trends in and predictors for adherence and preferential use of alcohol-based hand rubs, using multivariable analyses.

Setting.

Three intervention hospitals (a 660-bed acute and long-term care hospital, a 120-bed community hospital, and a 600-bed public teaching hospital) and a control hospital (a 700-bed university teaching hospital).

Intervention.

At the intervention hospitals, we introduced or increased the availability of alcohol-based hand rub, initiated an interactive education program, and developed a poster campaign; at the control hospital, we only increased the availability of alcohol-based hand rub.

Results.

We observed 6,948 hand hygiene opportunities. The frequency of hand hygiene performance or glove use significantly increased during the study period at the intervention hospitals but not at the control hospital; the maximum quarterly frequency of hand hygiene performance or glove use at intervention hospitals (74%, 80%, and 77%) was higher than that at the control hospital (59%). By multivariable analysis, preferential use of alcohol-based hand rubs rather than soap and water for hand hygiene was more likely among workers at intervention hospitals compared with nonintervention hospitals (adjusted odds ratio, 4.6 [95% confidence interval, 3.3-6.4]) and more likely among physicians (adjusted odds ratio, 1.4 [95% confidence interval, 1.2-1.8]) than among nurses at intervention hospitals. A significantly reduced incidence of antimicrobial-resistant bacteria among isolates from clinical culture was found at a single intervention hospital, which had the greatest increase in the frequency of hand hygiene performance.

Conclusions.

During a 3-year period, a multimodal intervention program increased adherence to hand hygiene recommendations, especially to the use of alcohol-based hand rubs. In one hospital, a concomitant reduction was found in the incidence of antimicrobial-resistant bacteria among isolates from clinical cultures.

Unnecessary Use of Central Venous Catheters: The Need to Look Outside the Intensive Care Unit

We developed criteria for justifiable CVC use and evaluated CVC use in a public hospital. Unjustified CVC-days were more common for non-ICU patients compared with ICU patients. Also, insertion-site dressings were less likely to be intact on non-ICU patients. Interventions to reduce CVC-associated bloodstream infections should include non-ICU patients.

Multicenter evaluation of computer automated versus traditional surveillance of hospital-acquired bloodstream infections

OBJECTIVE

Central line-associated bloodstream infection (BSI) rates are a key quality metric for comparing hospital quality and safety. Traditional BSI surveillance may be limited by interrater variability. We assessed whether a computer-automated method of central line-associated BSI detection can improve the validity of surveillance.

DESIGN

Retrospective cohort study.

SETTING

Eight medical and surgical intensive care units (ICUs) in 4 academic medical centers.

METHODS

Traditional surveillance (by hospital staff) and computer algorithm surveillance were each compared against a retrospective audit review using a random sample of blood culture episodes during the period 2004-2007 from which an organism was recovered. Episode-level agreement with audit review was measured with κ statistics, and differences were assessed using the test of equal κ coefficients. Linear regression was used to assess the relationship between surveillance performance (κ) and surveillance-reported BSI rates (BSIs per 1,000 central line-days).

RESULTS

We evaluated 664 blood culture episodes. Agreement with audit review was significantly lower for traditional surveillance (κ [95% confidence interval (CI) = 0.44 [0.37-0.51]) than computer algorithm surveillance (κ [95% CI] = 0.58; P = .001). Agreement between traditional surveillance and audit review was heterogeneous across ICUs (P = .01); furthermore, traditional surveillance performed worse among ICUs reporting lower (better) BSI rates (P = .001). In contrast, computer algorithm performance was consistent across ICUs and across the range of computer-reported central line-associated BSI rates. Conclusions: Compared with traditional surveillance of bloodstream infections, computer automated surveillance improves accuracy and reliability, making interfacility performance comparisons more valid.

CAPriCORN: Chicago Area Patient-Centered Outcomes Research Network

The Chicago Area Patient-Centered Outcomes Research Network (CAPriCORN) represents an unprecedented collaboration across diverse healthcare institutions including private, county, and state hospitals and health systems, a consortium of Federally Qualified Health Centers, and two Department of Veterans Affairs hospitals. CAPriCORN builds on the strengths of our institutions to develop a cross-cutting infrastructure for sustainable and patient-centered comparative effectiveness research in Chicago. Unique aspects include collaboration with the University HealthSystem Consortium to aggregate data across sites, a centralized communication center to integrate patient recruitment with the data infrastructure, and a centralized institutional review board to ensure a strong and efficient human subject protection program. With coordination by the Chicago Community Trust and the Illinois Medical District Commission, CAPriCORN will model how healthcare institutions can overcome barriers of data integration, marketplace competition, and care fragmentation to develop, test, and implement strategies to improve care for diverse populations and reduce health disparities.

The importance of long-term acute care hospitals in the regional epidemiology of Klebsiella pneumoniae carbapenemase-producing Enterobacteriaceae

BACKGROUND

In the United States, Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae are increasingly detected in clinical infections; however, the colonization burden of these organisms among short-stay and long-term acute care hospitals is unknown.

METHODS

Short-stay acute care hospitals with adult intensive care units (ICUs) in the city of Chicago were recruited for 2 cross-sectional single-day point prevalence surveys (survey 1, July 2010-January 2011; survey 2, January-July 2011). In addition, all long-term acute care hospitals (LTACHs) in the Chicago region (Cook County) were recruited for a single-day point prevalence survey during January-May 2011. Swab specimens were collected from rectal, inguinal, or urine sites and tested for Enterobacteriaceae carrying blaKPC.

RESULTS

We surveyed 24 of 25 eligible short-stay acute care hospitals and 7 of 7 eligible LTACHs. Among LTACHs, 30.4% (119 of 391) of patients were colonized with KPC-producing Enterobacteriaceae, compared to 3.3% (30 of 910) of short-stay hospital ICU patients (prevalence ratio, 9.2; 95% confidence interval, 6.3-13.5). All surveyed LTACHs had patients harboring KPC (prevalence range, 10%-54%), versus 15 of 24 short-stay hospitals (prevalence range, 0%-29%). Several patient-level covariates present at the time of survey-LTACH facility type, mechanical ventilation, and length of stay-were independent risk factors for KPC-producing Enterobacteriaceae colonization.

CONCLUSIONS

We identified high colonization prevalence of KPC-producing Enterobacteriaceae among patients in LTACHs. Patients with chronic medical care needs in long-term care facilities may play an important role in the spread of these extremely drug-resistant pathogens.

Effects of 2- vs 4-week attending physician inpatient rotations on unplanned patient revisits, evaluations by trainees, and attending physician burnout: a randomized trial

CONTEXT

Data are sparse on the effect of varying the durations of internal medicine attending physician ward rotations.

OBJECTIVE

To compare the effects of 2- vs 4-week inpatient attending physician rotations on unplanned patient revisits, attending evaluations by trainees, and attending propensity for burnout.

DESIGN, SETTING, AND PARTICIPANTS

Cluster randomized crossover noninferiority trial, with attending physicians as the unit of crossover randomization and 4-week rotations as the active control, conducted in a US university-affiliated teaching hospital in academic year 2009. Participants were 62 attending physicians who staffed at least 6 weeks of inpatient service, the 8892 unique patients whom they discharged, and the 147 house staff and 229 medical students who evaluated their performance.

INTERVENTION

Assignment to random sequences of 2- and 4-week rotations.

MAIN OUTCOME MEASURES

Primary outcome was 30-day unplanned revisits (visits to the hospital's emergency department or urgent ambulatory clinic, unplanned readmissions, and direct transfers from neighboring hospitals) for patients discharged from 2- vs 4-week within-attending-physician rotations. Noninferiority margin was a 2% increase (odds ratio [OR] of 1.13) in 30-day unplanned patient revisits. Secondary outcomes were length of stay; trainee evaluations of attending physicians; and attending physician reports of burnout, stress, and workplace control.

RESULTS

Among the 8892 patients, there were 2437 unplanned revisits. The percentage of 30-day unplanned revisits for patients of attending physicians on 2-week rotations was 21.2% compared with 21.5% for 4-week rotations (mean difference, -0.3%; 95% CI, -1.8% to +1.2%). The adjusted OR of a patient having a 30-day unplanned revisit after 2- vs 4-week rotations was 0.97 (1-sided 97.5% upper confidence limit, 1.07; noninferiority P = .007). Average length of stay was not significantly different (geometric means for 2- vs 4-week rotations were 67.2 vs 67.5 hours; difference, -0.9%; 95% CI, -4.7% to +2.9%). Attending physicians were more likely to score lower in their ability to evaluate trainees after 2- vs 4-week rotations by both house staff (41% vs 28% rated less than perfect; adjusted OR, 2.10; 95% CI, 1.50-3.02) and medical students (82% vs 69% rated less than perfect; adjusted OR, 1.41; 95% CI, 1.06-2.10). They were less likely to report higher scores of both burnout severity (16% vs 35%; adjusted OR, 0.39; 95% CI, 0.26-0.58) and emotional exhaustion (19% vs 37%; adjusted OR, 0.45; 95% CI, 0.31 to 0.64) after 2- vs 4-week rotations.

CONCLUSIONS

The use of 2-week inpatient attending physician rotations compared with 4-week rotations did not result in an increase in unplanned patient revisits. It was associated with better self-rated measures of attending physician burnout and emotional exhaustion but worse evaluations by trainees.

TRIAL REGISTRATION

clinicaltrials.gov Identifier: NCT00930111.

A cohort study investigating compliance with guidelines for platelet count monitoring during heparin thromboprophylaxis

BACKGROUND

Heparin is the most common agent used for prevention of venous thromboembolism. To promote early detection of heparin-induced thrombocytopenia, guidelines recommend episodic platelet count monitoring for specified patient populations. However, physician compliance with these guidelines has never been reported for patients receiving heparin for pharmacologic prophylaxis.

AIM

The aim of this study was to evaluate the frequency of and factors associated with physician failure to monitor patient platelet counts.

RESULTS

We conducted a retrospective cohort study of 2350 admissions of patients aged ≥ 18 years who received ≥ 4 consecutive days of prophylactic heparin. There was nonadherence to monitoring recommendations in 659 (28%) patients. Monitoring was not more likely among patients for whom monitoring was recommended compared with patients for whom no monitoring was recommended (31% vs 27%; adjusted hazard ratio, 0.9; 95% CI, 0.7-1.1). Compared with patients admitted to the general medicine service, monitoring was significantly less common among patients admitted to orthopedic surgery or obstetric-gynecologic services (adjusted hazard ratio, 1.6; 95% CI, 1.1-2.2 and adjusted hazard ratio, 2.4; 95% CI, 1.8-3.2, respectively). A decrease in platelet count (≥ 50%) was detected in 90 (4%) patients, but in only 12 (11%) patients was heparin stopped, and in only 11 (12%) patients were heparin-induced thrombocytopenia antibody levels obtained. Of the 11 patients for whom heparin-induced thrombocytopenia antibody levels were obtained, 6 (0.26% of the patient population) were positive.

CONCLUSION

We found that compliance by physicians with platelet count monitoring recommendations was poor for patients who had received heparin for venous thromboembolism prophylaxis, and platelet count monitoring appeared to be unrelated to American College of Chest Physicians recommendations for routine monitoring. Compliance was particularly poor in orthopedic surgery and obstetric-gynecologic services.

Quality of traditional surveillance for public reporting of nosocomial bloodstream infection rates

CONTEXT

Central line-associated bloodstream infection (BSI) rates, determined by infection preventionists using the Centers for Disease Control and Prevention (CDC) surveillance definitions, are increasingly published to compare the quality of patient care delivered by hospitals. However, such comparisons are valid only if surveillance is performed consistently across institutions.

OBJECTIVE

To assess institutional variation in performance of traditional central line-associated BSI surveillance.

DESIGN, SETTING, AND PARTICIPANTS

We performed a retrospective cohort study of 20 intensive care units among 4 medical centers (2004-2007). Unit-specific central line-associated BSI rates were calculated for 12-month periods. Infection preventionists, blinded to study participation, performed routine prospective surveillance using CDC definitions. A computer algorithm reference standard was applied retrospectively using criteria that adapted the same CDC surveillance definitions.

MAIN OUTCOME MEASURES

Correlation of central line-associated BSI rates as determined by infection preventionist vs the computer algorithm reference standard. Variation in performance was assessed by testing for institution-dependent heterogeneity in a linear regression model.

RESULTS

Forty-one unit-periods among 20 intensive care units were analyzed, representing 241,518 patient-days and 165,963 central line-days. The median infection preventionist and computer algorithm central line-associated BSI rates were 3.3 (interquartile range [IQR], 2.0-4.5) and 9.0 (IQR, 6.3-11.3) infections per 1000 central line-days, respectively. Overall correlation between computer algorithm and infection preventionist rates was weak (ρ = 0.34), and when stratified by medical center, point estimates for institution-specific correlations ranged widely: medical center A: 0.83; 95% confidence interval (CI), 0.05 to 0.98; P = .04; medical center B: 0.76; 95% CI, 0.32 to 0.93; P = .003; medical center C: 0.50, 95% CI, -0.11 to 0.83; P = .10; and medical center D: 0.10; 95% CI -0.53 to 0.66; P = .77. Regression modeling demonstrated significant heterogeneity among medical centers in the relationship between computer algorithm and expected infection preventionist rates (P < .001). The medical center that had the lowest rate by traditional surveillance (2.4 infections per 1000 central line-days) had the highest rate by computer algorithm (12.6 infections per 1000 central line-days).

CONCLUSIONS

Institutional variability of infection preventionist rates relative to a computer algorithm reference standard suggests that there is significant variation in the application of standard central line-associated BSI surveillance definitions across medical centers. Variation in central line-associated BSI surveillance practice may complicate interinstitutional comparisons of publicly reported central line-associated BSI rates.

Does cholecystectomy status influence the common bile duct diameter? A matched-pair analysis

The common bile duct (CBD) diameter is one factor that clinicians use when deciding on invasive evaluation for intra-ductal pathology, e.g., endoscopic retrograde cholangiopancreatography. Previous studies and gastrointestinal and radiological textbook authors report disparate interpretations. These inconsistent interpretations likely result from methodological limitations in prior studies. The purpose of this work is to primarily compare the CBD diameter among patients with and without prior cholecystectomy and secondarily to compare proximal and distal CBD measurements. Among 40 matched pairs, post-cholecystectomy patients had larger mean CBD diameters at proximal (7.0 vs. 5.4 mm; P < 0.001) and distal (5.9 vs. 4.6 mm; P < 0.001) sites. Post-cholecystectomy patients were also more likely to exceed the 6-mm cut point for proximal (80 vs. 28%; P < 0.001) or distal (58 vs. 20%; P = 0.003) measurements. Incidental radiographic detection of enlarged CBDs among post-cholecystectomy patients is common; therefore, clinicians should use clinical determinants to guide decisions about additional costly or potentially harmful evaluation for intraductal pathology.

Clinical trial of standing-orders strategies to increase the inpatient influenza vaccination rate

We compared strategies to increase the rate of influenza vaccination. A written standing-orders policy that enabled nurses to vaccinate patients was compared with augmentation of the standing-orders policy with either electronic opt-out orders for physicians or electronic reminders to nurses. Use of opt-out orders yielded the highest vaccination rate (12% of patients), followed by use of nursing reminders (6%); use of the standing-orders policy alone was ineffective.

Use of clinical decision support to increase influenza vaccination: multi-year evolution of the system

Despite recognition that clinical decision support (CDS) can improve patient care, there has been poor penetration of this technology into healthcare settings. We used CDS to increase inpatient influenza vaccination during implementation of an electronic medical record, in which pharmacy and nursing transactions increasingly became electronic. Over three influenza seasons we evaluated standing orders, provider reminders, and pre-selected physician orders. A pre-intervention cross-sectional survey showed that most patients (95%) met criteria for vaccination. During our intervention, physicians were increasingly likely to accept pre-selected vaccination orders, Year 1 (47%), Year 2 (77%), Year 3 (83%); however vaccine administration by nurses was suboptimal. As electronic medical record functionality improved, patient receipt of vaccine increased dramatically, Year 1 [0/36; 0%], Year 2 [8/66; 12%], Year 3 [286/805; 36%]. Successful use of clinical decision support to increase inpatient influenza vaccination only occurred after initiation of CPOE for all medications and integration of an electronic medication administration record. Also, since most patients met criteria for influenza vaccination, complicated logic to identify high-risk patients was unnecessary.

Tobacco, alcohol, and drug use among hospital patients: concurrent use and willingness to change

BACKGROUND

Data are limited on concurrent smoking and substance use among hospital patients. To better inform hospital-based intervention strategies, we evaluated the prevalence and concurrent use of these behaviors. This study evaluated the association between tobacco, alcohol, and other drug use, compared willingness to quit smoking among patients with and without substance use, and evaluated the relationship between willingness to quit smoking and readiness to change substance use.

METHODS

This study was a cross-sectional survey of non-Intensive Care Unit hospital patients at 2 public hospitals (a 464-bed tertiary-care hospital and a 100-bed community hospital) by bedside interview. Severity of use and willingness to change behavior was determined. We evaluated the association between smoking and substance use by multivariable methods.

RESULTS

Of 7,391 patients with known smoking status, 2,684 (36%) were current smokers. Among them, 1,376 hospitalized smokers (51%) had concurrent substance use. Among the 1,972 patients with at-risk alcohol or drug use, the prevalence of smoking was 70% compared to 24% for non-substance users (P < .01). Compared to other patients who smoked, substance-dependent patients were more likely (Prevalence Rate Ratio = 1.4, 95% Confidence Interval = 1.1-1.9) to be moderate to heavy smokers. Regardless of substance use pattern, most patients (60%) expressed a desire to immediately quit smoking.

CONCLUSION

Hospital patients who describe at-risk substance use are likely to smoke and express willingness to quit smoking. Given the prevalence of concurrent smoking and substance use and patients' desire to change both behaviors, there is a need for coordination of substance use and smoking cessation interventions.

Effect of a school-entry vaccination requirement on racial and ethnic disparities in hepatitis B immunization coverage levels among public school students

OBJECTIVE

We evaluated the overall effect of Illinois' school-entry mandate on hepatitis B vaccination coverage levels and racial/ethnic differences in vaccination coverage before and after the mandate.

METHODS

In 1997, the Illinois Department of Public Health mandated hepatitis B vaccination before entry into 5th grade. We conducted a retrospective cohort study of 6 consecutive Chicago public schools' 12th-grade classes; 4 entered 5th grade before the mandate (premandate cohorts) and 2 afterward (postmandate cohorts). We used Chicago public schools' vaccination database and calculated annual coverage levels for 2nd through 12th grades; the cohorts entered 12th grade during 2000-2005. We compared hepatitis B vaccination coverage levels according to race/ethnicity and coverage levels for the premandate and postmandate cohorts.

RESULTS

We evaluated 106 541 students. The postmandate cohort had significantly higher hepatitis B vaccination coverage levels than the premandate cohort at 5th-grade (38.2% vs 4.3%) and 9th-grade (85.0% vs 37.4%) entry. For 9th-grade students, compared with white students, black students were less likely to have received hepatitis B vaccination before the mandate; this disparity decreased for the first postmandate cohort. For Hispanic students, the disparity was less pronounced and also decreased after the mandate. By 9th grade in the postmandate cohorts, coverage levels for all racial/ethnic groups exceeded 80%.

CONCLUSIONS

There was a dramatic decrease in the disparity of hepatitis B vaccination coverage between white and black or Hispanic students. School-entry requirements effectively increased hepatitis B vaccination coverage levels regardless of race or ethnicity and should be considered for other recently recommended adolescent vaccines.

House Staff Attitudes About Influenza Vaccination After Participation in a Clinical Trial to Improve Vaccination of Hospital Patients

We surveyed house staff who had participated in a trial that compared influenza vaccination strategies for inpatients. House staff who were exposed to computer-generated vaccination orders were more likely to report that they recommended vaccination to their inpatients and outpatients, compared with house staff who were not exposed to a vaccination intervention. Also, house staff did not recognize regnant women as a high-priority population for influenza vaccination.

Effectiveness of chlorhexidine bathing to reduce catheter-associated bloodstream infections in medical intensive care unit patients

OBJECTIVE

To determine whether patients bathed daily with chlorhexidine gluconate (CHG) have a lower incidence of primary bloodstream infections (BSIs) compared with patients bathed with soap and water.

METHODS

The study design was a 52-week, 2-arm, crossover (ie, concurrent control group) clinical trial with intention-to-treat analysis. The study setting was the 22-bed medical intensive care unit (MICU), which comprises 2 geographically separate, similar 11-bed units, of the John H. Stroger Jr (Cook County) Hospital, a 464-bed public teaching hospital in Chicago, Illinois. The study population comprised 836 MICU patients. During the first of 2 study periods (28 weeks), 1 hospital unit was randomly selected to serve as the intervention unit in which patients were bathed daily with 2% CHG-impregnated washcloths (Sage 2% CHG cloths; Sage Products Inc, Cary, Illinois); patients in the concurrent control unit were bathed daily with soap and water. After a 2-week wash-out period at the end of the first period, cleansing methods were crossed over for 24 more weeks. Main outcome measures included incidences of primary BSIs and clinical (culture-negative) sepsis (primary outcomes) and incidences of other infections (secondary outcomes).

RESULTS

Patients in the CHG intervention arm were significantly less likely to acquire a primary BSI (4.1 vs 10.4 infections per 1000 patient days; incidence difference, 6.3 [95% confidence interval, 1.2-11.0). The incidences of other infections, including clinical sepsis, were similar between the units. Protection against primary BSI by CHG cleansing was apparent after 5 or more days in the MICU.

CONCLUSION

Daily cleansing of MICU patients with CHG-impregnated cloths is a simple, effective strategy to decrease the rate of primary BSIs.

Evolution of clinical decision support to increase influenza vaccination

Over three influenza seasons spanning four years we evaluated the effect of standing orders, reminders, and iterations of Clinical Decision Support (CDS) to increase influenza (flu) vaccination among inpatients. Using CDS, coverage increased over each season: (0%, 12%, 35%). However, success was realized only after integration of the electronic medication administration record (E-MAR). Standing orders and reminders were ineffective.

An educational intervention to improve antimicrobial use in a hospital-based long-term care facility

OBJECTIVES

To improve antimicrobial use in patients receiving long-term care (LTC).

DESIGN

Prospective, quasi-experimental before-after assessment of the effects of physician education and guideline implementation.

SETTING

Public LTC and acute care hospital.

PARTICIPANTS

Twenty salaried internists who provided most of the medical care to LTC patients.

INTERVENTION

National guidelines, hospital resistance data, and physician feedback were incorporated into a series of four teaching sessions presented over 18 months and into booklets detailing institutional guidelines on the optimal management of common LTC infection syndromes.

MEASUREMENTS

One hundred randomly selected LTC patients treated with antimicrobials were reviewed before these interventions were implemented and 100 after, and measures of the quality of care were compared. The effect of the interventions on antimicrobial days and starts were also assessed using interrupted time series analysis.

RESULTS

Charted clinical abnormalities met guideline diagnostic criteria (62% vs 38%, P=.006), and initial therapy agreed with guideline recommendations (39% vs 11%, P<.001), more often in the post- than in the preintervention cohort. Mean census-adjusted monthly LTC antimicrobial days fell 29.7%, and antimicrobial starts fell 25.9% during the intervention period; both decreases were sustained during the 2-year postintervention period.

CONCLUSION

The teaching and guideline intervention improved the quality and reduced the quantity of antimicrobial use in LTC patients.

Firm-based trial to improve central venous catheter insertion practices

BACKGROUND

Central venous catheters placed in femoral veins increase the risk of complications. At our institution, residents place most catheters in the femoral vein.

OBJECTIVE

Determine whether a hands-on educational session reduced femoral venous catheterization and improved residents' confidence and adherence to recommendations for infection control.

DESIGN

Firm-based clinical trial between November 2004 and March 2005.

SETTING

General medical wards of Cook County (Stroger) Hospital (Chicago, IL), a public teaching hospital.

PARTICIPANTS

Internal medicine residents (n = 150).

INTERVENTION

Before their 4-week rotation, intervention-firm residents received a lecture and practiced placing catheters in mannequins; control-firm residents received the usual training.

MEASUREMENTS

Venous insertion site, adherence to recommendations for infection control, knowledge and confidence about catheter insertion, and catheter-associated complications

RESULTS

Residents inserted 54 catheters, or 0.24 insertions per resident per 4-week rotation. There was a nonsignificant decrease in femoral insertions for nondialysis catheters in the intervention group compared to the control group (44% vs. 58%), difference: -14% (95% CI, -52% to 24%). The intervention significantly increased residents' knowledge of complications related to femoral vein catheterization and temporarily increased their confidence about placing internal jugular or subclavian venous catheters. Intervention-group residents were more likely to use masks during catheterization (risk ratio, 2.2; 95% CI, 1.3-2.7), but other practices were similar.

CONCLUSIONS

Our intervention improved residents' knowledge of complications and use of masks during catheter insertion; however, it did not significantly change venous insertion sites. Catheter insertions on our general medicine wards are infrequent, and the skills acquired during the skills-building session may have deteriorated given the few clinical opportunities for reinforcement.

Effect of education on hand hygiene beliefs and practices: a 5-year program

To evaluate infection control and hand hygiene understanding at 3 public hospitals, we surveyed 4,345 healthcare workers (HCWs) 3 times during a 5-year infection control intervention. The preference for the use of alcohol hand rub for hand hygiene increased dramatically; in nurses, it increased from 14% to 34%; in physicians, 4.3% to 51%; and in allied HCWs, 12% to 44%. Study year, infection control interactive education-session attendance, infection control knowledge, and being a physician or allied HCW independently predicted a preference for alcohol hand rub.

Prospective cohort study of central venous catheters among internal medicine ward patients

BACKGROUND

Central venous catheter (CVC) use is less well described for patients outside the intensive care unit. We evaluated CVCs and the associated bloodstream infection rate among patients admitted to the general medical service.

METHODS

We performed a prospective cohort study of patients who had a CVC on admission or inserted during their stay on the general medical service in a public teaching hospital, November 15, 2004, to March 31, 2005.

RESULTS

We identified 106 CVCs, 52 were present on admission and 54 were inserted; there were 682 catheter-days. The primary bloodstream infection rate was 4.4 per 1000 catheter-days (95% CI: 0.9-13): highest for catheters inserted in the emergency department compared with those inserted on other units (24 vs 1.7 per 1000 catheter-days), P = .045. By multivariable analysis, inadequate dressings were more likely among patients with a body mass index > or =30 kg/m(2), adjusted odds ratio, 3.4 (95% CI: 1.4-8.0).

CONCLUSIONS

Many CVCs had previously been inserted in the emergency department or intensive care unit; therefore, strategies to reduce bloodstream infections that focus on ward insertion practices may not dramatically reduce bloodstream infection rates. Intervention strategies should target improved dressing care and consideration of early removal or replacement of catheters inserted in the emergency department.
