Costs versus earnings in colon surgery and coronary artery bypass grafting under a prospective payment system: Sufficient financial incentives to reduce surgical site infections?

Based on a surgical site infection (SSI) cohort at an academic center, we showed a median potentially preventable loss per non-SSI case of $17,916 in colon surgery and of $34,741 in coronary artery bypass grafting.

Obtaining blood cultures by venipuncture versus from central lines: impact on blood culture contamination rates and potential effect on central line-associated bloodstream infection reporting.

OBJECTIVE: Reduce the frequency of contaminated blood cultures that meet National Healthcare Safety Network definitions for a central line-associated bloodstream infection (CLABSI). DESIGN: An observational study. SETTING: A 500-bed university-affiliated hospital. METHODS: A new blood culture policy discouraged drawing blood samples from central lines. Phlebotomists were reeducated regarding aseptic technique when obtaining blood samples by venipuncture. The intravenous therapy team was taught how to draw blood samples by venipuncture and served as a backup when phlebotomists were unable to obtain blood samples. A 2-nurse protocol and a special supply kit for obtaining blood samples from catheters were developed. Rates of blood culture contamination were monitored by the microbiology laboratory. RESULTS: The proportion of blood samples obtained for culture from central lines decreased from 10.9% during January-June 2010 to 0.4% during July-December 2012 (P < .001). The proportion of blood cultures that were contaminated decreased from 84 (1.6%) of 5,274 during January-June 2010 to 21 (0.5%) of 4,245 during January-June 2012 (P < .001). Based on estimated excess hospital costs of $3,000 per contaminated blood culture, the reduction in blood culture contaminants yielded an estimated annualized savings of $378,000 in 2012 when compared to 2010. In mid-2010, 3 (30%) of 10 reported CLABSIs were suspected to represent blood culture contamination compared with none of 6 CLABSIs reported from mid-November 2010 through June 2012 (P = 0.25). CONCLUSIONS: Multiple interventions resulted in a reduction in blood culture contamination rates and substantial cost savings to the hospital, and they may have reduced the number of reportable CLABSIs.

Prevention of central line-associated bloodstream infections in hemodialysis patients.

An increasing proportion of central line-associated bloodstream infections (CLABSIs) are seen in outpatient settings. Many of such infections are due to hemodialysis catheters (HD-CLABSIs). Such infections are associated with substantial morbidity, mortality, and excess healthcare costs. Patients who receive dialysis through a catheter are 2-3 times more likely to be hospitalized for infection and to die of septic complications than dialysis patients with grafts or fistulas. Prevention measures include minimizing the use of hemodialysis catheters, use of CLABSI prevention bundles for line insertion and maintenance, and application of antimicrobial ointment to the catheter exit site. Instillation into dialysis catheters of antimicrobial solutions that remain in the catheter lumen between dialyses (antimicrobial lock solutions) has been studied, but it is not yet standard practice in some dialysis units. At least 34 studies have evaluated the impact of antimicrobial lock solutions on HD-CLABSI rates. Thirty-two (94%) of the 34 studies demonstrated reductions in HD-CLABSI rates among patients treated with antimicrobial lock solutions. Recent multicenter randomized controlled trials demonstrated that the use of such solutions resulted in significantly lower HD-CLABSI rates, even though such rates were low in control groups. The available evidence supports more routine use of antimicrobial lock solutions as an HD-CLABSI prevention measure in hemodialysis units.

Who is really caring for your environment of care? Developing standardized cleaning procedures and effective monitoring techniques.

Health care facilities have procedures for cleaning patient care environments, but there is often confusion about the division of labor when it comes to cleaning responsibilities. In addition, systems to monitor cleaning effectiveness are frequently suboptimal. In 2007, a multidisciplinary task force revised policies outlining staff responsibilities for cleaning in-patient nursing care units and chose a monitoring system using a specialized adenosine triphosphate bioluminescence test.
