An evidence-based intervention resulted in a large and sustained reduction (up to 66%) in rates of catheter-related bloodstream infection that was maintained throughout the 18-month study period.

Objectives To evaluate the extent to which intensive care units participating in the initial Keystone ICU project sustained reductions in rates of catheter related bloodstream infections. Design Collaborative cohort study to implement and evaluate interventions to improve patients' safety. Setting Intensive care units predominantly in Michigan, USA. Intervention Conceptual model aimed at improving clinicians' use of five evidence based recommendations to reduce rates of catheter related bloodstream infections rates, with measurement and feedback of infection rates. During the sustainability period, intensive care unit teams were instructed to integrate this intervention into staff orientation, collect monthly data from hospital infection control staff, and report infection rates to appropriate stakeholders. Main outcome measures Quarterly rate of catheter related bloodstream infections per 1000 catheter days during the sustainability period (19-36 months after implementation of the intervention). Results Ninety (87%) of the original 103 intensive care units participated, reporting 1532 intensive care unit months of data and 300 310 catheter days during the sustainability period. The mean and median rates of catheter related bloodstream infection decreased from 7.7 and 2.7 (interquartile range 0.6-4.8) at baseline to 1.3 and 0 (0-2.4) at 16-18 months and to 1.1 and 0 (0.0-1.2) at 34-36 months post-implementation. Multilevel regression analysis showed that incidence rate ratios decreased from 0.68 (95% confidence interval 0.53 to 0.88) at 0-3 months to 0.38 (0.26 to 0.56) at 16-18 months and 0.34 (0.24-0.48) at 34-36 months post-implementation. During the sustainability period, the mean bloodstream infection rate did not significantly change from the initial 18 month post-implementation period (−1%, 95% confidence interval −9% to 7%). ConclusionsThe reduced rates of catheter related bloodstream infection achieved in the initial 18 month post-implementation period were sustained for an additional 18 months as participating intensive care units integrated the intervention into practice. Broad use of this intervention with achievement of similar results could substantially reduce the morbidity and costs associated with catheter related bloodstream infections.

PURPOSE To compare outcomes between lung stereotactic radiotherapy (SBRT) and wedge resection for stage I non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS One hundred twenty-four patients with T1-2N0 NSCLC underwent wedge resection (n = 69) or image-guided lung SBRT (n = 58) from February 2003 through August 2008. All were ineligible for anatomic lobectomy; of those receiving SBRT, 95% were medically inoperable, with 5% refusing surgery. Mean forced expiratory volume in 1 second and diffusing capacity of lung for carbon monoxide were 1.39 L and 12.0 mL/min/mmHg for wedge versus 1.31 L and 10.14 mL/min/mmHg for SBRT (P = not significant). Mean Charlson comorbidity index and median age were 3 and 74 years for wedge versus 4 and 78 years for SBRT (P < .01, P = .04). SBRT was volumetrically prescribed as 48 (T1) or 60 (T2) Gy in four to five fractions. Results Median potential follow-up is 2.5 years. At 30 months, no significant differences were identified in regional recurrence (RR), locoregional recurrence (LRR), distant metastasis (DM), or freedom from any failure (FFF) between the two groups (P > .16). SBRT reduced the risk of local recurrence (LR), 4% versus 20% for wedge (P = .07). Overall survival (OS) was higher with wedge but cause-specific survival (CSS) was identical. Results excluding synchronous primaries, nonbiopsied tumors, or pathologic T4 disease (wedge satellite lesion) showed reduced LR (5% v 24%, P = .05), RR (0% v 18%, P = .07), and LRR (5% v 29%, P = .03) with SBRT. There were no differences in DM, FFF, or CSS, but OS was higher with wedge. CONCLUSION Both lung SBRT and wedge resection are reasonable treatment options for stage I NSCLC patients ineligible for anatomic lobectomy. SBRT reduced LR, RR, and LRR. In this nonrandomized population of patients selected for surgery versus SBRT (medically inoperable) at physician discretion, OS was higher in surgical patients. SBRT and surgery, however, had identical CSS.
