Objective.To determine the effect of a bundle of infection control interventions on the horizontal transmission ofKlebsiella pneumoniaecarbapenemase (KPC)-producingK. pneumoniaeduring an outbreak.Design.Quasi-experimental study.Setting.Long-term acute care hospital.Intervention.On July 23,2008, a bundled intervention was implemented: daily 2% Chlorhexidine gluconate baths for patients, enhanced environmental cleaning, surveillance cultures at admission, serial point prevalence surveillance (PPS), isolation precautions, and training of personnel. Baseline PPS was performed before the intervention was implemented. Any gram-negative rod isolate suspected of KPC production underwent a modified Hodge test and, if results were positive, confirmatory polymerase chain reaction testing. Clinical cases were defined to occur for patients whose samples yielded KPC-positive gram-negative rods in clinical cultures.Results.Baseline PPS performed on June 17, 2008, showed a prevalence of colonization with KPC-producing isolates of 21% (8 of 39 patients screened). After implementation of the intervention, monthly PPS was performed 5 times, which showed prevalences of colonization with KPC-producing isolates of 12%, 5%, 3%, 0%, and 0% (P< .001). From January 1, 2008, until the intervention, 8 KPC-positive clinical cases—suspected to be due to horizontal transmission—were detected. From implementation of the intervention through December 31, 2008, only 2 KPC-positive clinical cases, both in August 2008, were detected. From January 1 through December 31, 2008, 8 patients were detected as carriers of KPC-producing isolates at admission to the institution, 4 patients before and 4 patients after the intervention.Conclusion.A bundled intervention was successful in preventing horizontal spread of KPC-producing gram-negative rods in a long-term acute care hospital, despite ongoing admission of patients colonized with KPC producers.

Abstract Background Hand hygiene (HH) is the cornerstone of infection prevention and improved compliance has been associated with reduced healthcare-associated infections (HAIs). However, traditional methods for HH data collection have limitations and may not accurately reflect true compliance. We sought to evaluate whether an electronic hand hygiene monitoring system (HHMS) can improve data collection, compliance, and reduce HAIs. Methods A HHMS was implemented as part of a pilot at a single facility in June 2018 for all healthcare workers (HCWs) who entered patient rooms. The system prompted HCWs to perform HH with an audible and visual reminder emitted from a badge if a HH event had not been registered within specific timeframes of entering or exiting a patient room. The system captured compliance with preferential handwashing (soap and water) for at least 15 seconds upon exit of Clostridioides difficile (C. difficile) designated rooms. All HH data were collected by the HHMS. Hand hygiene compliance and HAI data were compared for the pre-intervention (June 2017-May 2018) and intervention periods (July 2018-March 2019). No changes were made to environmental cleaning protocols or compliance monitoring, nor in antibiotic stewardship practices. Results HH compliance by direct observation in the pre-intervention period was 91% (1,612 observations). HH compliance with the HHMS during the intervention period was 97% (2,778,402 observations). The mean monthly HH opportunities recorded during the pre-intervention period was 134, while the HHMS captured 308,711, a greater than 2,300-fold increase. The incidence of healthcare facility-onset C. difficile infections (HO-CDI) pre-intervention was 9.60 per 10,000 patient-days (41 GDH+/Toxin+ laboratory-identified [labID] events/42,726 patient-days). With the HHMS, HO-CDI decreased 70% (P = 0.0003) to 2.89 per 10,000 patient-days (9 labID events/31,169 patient-days). No policy changes in environmental cleaning of high-touch surfaces were made or observed during the pilot. Conclusion The use of an HHMS facilitated more comprehensive HH data and improved compliance. The preliminary findings also support an association between more robust HH compliance data and a significant decrease in toxin-producing CDI. Disclosures All authors: No reported disclosures.

OBJECTIVETo determine the scope, source, and mode of transmission of a multifacility outbreak of extensively drug-resistant (XDR)Acinetobacter baumannii.DESIGNOutbreak investigation.SETTING AND PARTICIPANTSResidents and patients in skilled nursing facilities, long-term acute-care hospital, and acute-care hospitals.METHODSA case was defined as the incident isolate from clinical or surveillance cultures of XDRAcinetobacter baumanniiresistant to imipenem or meropenem and nonsusceptible to all but 1 or 2 antibiotic classes in a patient in an Oregon healthcare facility during January 2012–December 2014. We queried clinical laboratories, reviewed medical records, oversaw patient and environmental surveillance surveys at 2 facilities, and recommended interventions. Pulsed-field gel electrophoresis (PFGE) and molecular analysis were performed.RESULTSWe identified 21 cases, highly related by PFGE or healthcare facility exposure. Overall, 17 patients (81%) were admitted to either long-term acute-care hospital A (n=8), or skilled nursing facility A (n=8), or both (n=1) prior to XDRA. baumanniiisolation. Interfacility communication of patient or resident XDR status was not performed during transfer between facilities. The rare plasmid-encoded carbapenemase geneblaOXA-237was present in 16 outbreak isolates. Contact precautions, chlorhexidine baths, enhanced environmental cleaning, and interfacility communication were implemented for cases to halt transmission.CONCLUSIONSInterfacility transmission of XDRA. baumanniicarrying the rare blaOXA-237was facilitated by transfer of affected patients without communication to receiving facilities.Infect Control Hosp Epidemiol2017;38:1335–1341

Carbapenem Resistant Enterobacteriaceae

Abstract Background Residents of long-term acute care hospitals (LTACHs) are considered important reservoirs of multidrug-resistant organisms, including Carbapenem-resistant Enterobacteriaceae (CRE). We conducted this study to define the characteristics of CRE-infected/colonized patients admitted to an LTACH and the molecular characteristics of the CRE isolates. Methods This retrospective study was conducted to collect information on demographic and comorbid conditions in CRE-colonized/infected patients admitted to a 77-bed LTACH in Detroit between January 2011 and July 2012. Data pertaining to hospital-related exposures were collected for 30 days before positive CRE culture. Polymerase chain reaction (PCR) gene amplification, repetitive sequence–based PCR, and multilocus sequence typing (MLST) were performed on 8 of the CRE isolates. Results The study cohort included 30 patients with CRE-positive cultures, 24 (80%) with infections, and 6 (20%) with colonization. The mean age of cohort was 69 ±12.41 years; 19 (63%) patients were ventilator-dependent, and 20 (67%) were treated with at least 1 antibiotic. Twenty-three (77%) patients had CRE detected following LTACH admission, and the median days from admission to CRE detection in these patients (interquartile range) was 25 (11–43). Seven more patients were already positive for CRE at the time of LTACH admission. Molecular genotyping and MLST of 8 CRE isolates demonstrated that all isolates belonged to the same strain type (ST258) and contained the blaKPC-3 sequence. Conclusions The majority of patients with CRE presented several days to weeks after LTACH admission, indicating possible organism acquisition in the LTACH itself. The genetic similarity of the CRE isolates tested could further indicate the occurrence of horizontal transmission in the LTACH or simply be representative of the regionally dominant strain.

Objective.To evaluate the effect of bathing patients with 2% chlorhexidine on the rates of central vascular catheter (CVC)–associated bloodstream infection (BSI) at a long-term acute care hospital (LTACH).Design.Quasi-experimental study.Setting.A 70-bed LTACH in the greater Chicago area.Patients.All consecutive patients admitted to the LTACH during the period from February 2006 to February 2008.Methods.For patients at the LTACH, daily 2% chlorhexidine baths were instituted during the period from September 2006 until May 2007 (ie, the intervention period). A preintervention period (in which patients were given daily soap-and-water baths) and a postintervention period (in which patients were given daily nonmedicated baths and weekly 2% chlorhexidine baths) were also observed. The rates of CVC-associated BSI and ventilator-associated pneumonia were analyzed for the intervention period and for the pre- and postintervention periods.Results.The rates of CVC-associated BSI were 9.5, 3.8, and 6.4 cases per 1,000 CVC-days during the preintervention, intervention, and postintervention periods, respectively. By the end of the intervention period, there was a net reduction of 99% in the CVC-associated BSI rate. No changes were seen in the rates of ventilator-associated pneumonia during the preintervention and intervention periods.Conclusion.Daily chlorhexidine baths appeared to be an effective intervention to reduce rates of CVC-associated BSI in an LTACH.

Objective: To determine whether burdens of chronic comorbid illnesses can predict the clinical course of prolonged mechanical ventilation (PMV)patients in a long-term, acute-care hospital (LTACH). Methods: Retrospective study of 866 consecutive PMV patients whose burdens of chronic comorbid illnesses were quantified using the Cumulative Illness Rating Scale (CIRS). Based on increasing CIRS scores, 6 groups were formed and compared: group A (≤25; n = 97), group B (26-28; n = 105), group C (29-31; n = 181), group D (32-34; n = 208), group E (35-37; n = 173), and group F (>37; n = 102). Results: As CIRS scores increased from group A to group F, rates of weaning success, home discharges, and LTACH survival declined progressively from 74% to 17%, 48% to 0%, and 79% to 21%, respectively (all P < .001). Negative correlations between the mean score of each CIRS group and correspondent outcomes also supported patients’ group allocation and an accurate prediction of their clinical course (all P < .01). Long-term survival progressively declined from a median survival time of 38.9 months in group A to 3.2 months in group F ( P < .001). Compared to group A, risk of death was 75% greater in group F ( P = .03). Noteworthy, PMV patients with CIRS score <25 showed greater ability to recover and a low likelihood of becoming chronically critically ill. Diagnostic accuracy of CIRS to predict likelihood of weaning success, home discharges, both LTACH and long-term survival was good (area under the curves ≥0.71; all P <.001). Conclusions: The burden of chronic comorbid illnesses was a strong prognostic indicator of the clinical course of PMV patients. Patients with lower CIRS values showed greater ability to recover and were less likely to become chronically critically ill. Thus, CIRS can be used to help guide clinicians caring for PMV patients in transfer decisions to and from postacute care setting.
