Risk factors for surgical site infection after abdominal hysterectomy, New York State, 2015-2018.

BACKGROUND: To identify risk factors for surgical site infections (SSIs) after abdominal hysterectomy (HYST) procedures using National Health care Safety Network (NHSN) data augmented with diagnosis codes available using administrative data. METHODS: We analyzed 66,001 HYST procedures in 166 New York State hospitals between January 2015 and December 2018, reported in NHSN, and matched to billing data. Risks factors for SSI after abdominal HYST were identified using logistic regression models. RESULTS: A total of 66,001 HYST procedures were analyzed. SSI was reported following 1,093 procedures, resulting in an infection rate of 1.66%. Risk factors associated with SSIs were open approach (not laparoscopic) with an adjusted odds ratio (AOR) of 2.72 and 95% confidence interval (CI) of 2.37-3.12, contaminated or dirty wound class (AOR 2.28, 95% CI 1.61-3.24), body mass index ≥30 (AOR 1.78, 95% CI 1.56-2.02), procedures lasting 186 minutes or more (AOR 1.78, 95% CI 1.56-2.02), American Society of Anesthesia (ASA) score ≥3 (AOR 1.74, 95% CI 1.52-1.99), gynecological cancer (AOR 1.54, 95% CI 1.32-1.80), and diabetes mellitus (AOR 1.46, 95% CI 1.24-1.70). CONCLUSIONS: Obesity, prolonged procedure duration, diabetes mellitus, wound contamination, open approach, ASA score ≥3, and gynecological cancer were significant independent risk factors associated with SSI after HYST.

Lessons learned from initial reporting of carbapenem-resistant Enterobacteriaceae in New York State hospitals, 2013-2014.

BACKGROUND: Carbapenem-resistant Enterobacteriaceae (CRE) are an urgent concern in health care in the United States because of high attributable mortality and versatile resistance mechanisms. CRE reporting was mandated in New York State (NYS) hospitals in July 2013. METHODS: Infection preventionists from the NYS Department of Health audited hospital-reported CRE data by comparing laboratory records with cases reported to the National Healthcare Safety Network (NHSN). Information regarding microbiology laboratory testing methodologies was obtained through a survey in October 2013. RESULTS: There were 1,151 CRE laboratory reports audited, with 13.6% determined not to have been reported to the NHSN when they should have been and 4.6% determined to be reported in error. There were a variety of errors, including lapses in surveillance and misinterpretation of the surveillance definition. CONCLUSION: Educational initiatives that include microbiology laboratory staff, improvements in the use of laboratory information systems to communicate with infection prevention, and updated NHSN definitions should improve the accuracy and consistency of CRE reporting in NYS.

Effect of 2013 National Healthcare Safety Network definition changes on central line bloodstream infection rates: audit results from the New York State Department of Health.

Surveillance criteria for central line-associated bloodstream infections (CLABSIs) are continually being refined to more accurately reflect infections related to central lines. An audit of 567 medical records from adult, pediatric, and neonatal intensive care unit patients with a central line and a positive blood culture showed a 16% decrease in CLABSI rates after the 2013 National Healthcare Safety Network definitions compared with the 2012 definitions.

Sustained reduction of central line-associated bloodstream infections outside the intensive care unit with a multimodal intervention focusing on central line maintenance.

BACKGROUND: Central venous catheter use is common outside the intensive care units (ICUs), but prevention in this setting is not well studied. We initiated surveillance for central line-associated bloodstream infections (CLABSIs) outside the ICU setting and studied the impact of a multimodal intervention on the incidence of CLABSIs across multiple hospitals. METHODS: This project was constructed as a prospective preintervention-postintervention design. The project comprised 3 phases (preintervention [baseline], intervention, and postintervention) over a 4.5-year period (2008-2012) and was implemented through a collaborative of 37 adult non-ICU wards at 6 hospitals in the Rochester, NY area. The intervention focused on engagement of nursing staff and leadership, nursing education on line care maintenance, competence evaluation, audits of line care, and regular feedback on CLABSI rates. Quarterly rates were compared over time in relation to intervention implementation. RESULTS: The overall CLABSI rate for all participating units decreased from 2.6/1000 line-days preintervention to 2.1/1,000 line-days during the intervention and to 1.3/1,000 line-days postintervention, a 50% reduction (95% confidence interval, .40-.59) compared with the preintervention period (P .0179). CONCLUSION: A multipronged approach blending both the adaptive and technical aspects of care including front line engagement, education, execution of best practices, and evaluation of both process and outcome measures may provide an effective strategy for reducing CLABSI rates outside the ICU.
