Sustained improvement in hospital cleaning associated with a novel education and culture change program for environmental services workers.

OBJECTIVE: To sustainably improve cleaning of high-touch surfaces (HTSs) in acute-care hospitals using a multimodal approach to education, reduction of barriers to cleaning, and culture change for environmental services workers. DESIGN: Prospective, quasi-experimental, before-and-after intervention study. SETTING: The study was conducted in 2 academic acute-care hospitals, 2 community hospitals, and an academic pediatric and women's hospital. PARTICIPANTS: Frontline environmental services workers. INTERVENTION: A 5-module educational program, using principles of adult learning theory, was developed and presented to environmental services workers. Audience response system (ARS), videos, demonstrations, role playing, and graphics were used to illustrate concepts of and the rationale for infection prevention strategies. Topics included hand hygiene, isolation precautions, personal protective equipment (PPE), cleaning protocols, and strategies to overcome barriers. Program evaluation included ARS questions, written evaluations, and objective assessments of occupied patient room cleaning. Changes in hospital-onset C. difficile infection (CDI) and methicillin-resistant S. aureus (MRSA) bacteremia were evaluated. RESULTS: On average, 357 environmental service workers participated in each module. Most (93%) rated the presentations as 'excellent' or 'very good' and agreed that they were useful (95%), reported that they were more comfortable donning/doffing PPE (91%) and performing hand hygiene (96%) and better understood the importance of disinfecting HTSs (96%) after the program. The frequency of cleaning individual HTSs in occupied rooms increased from 26% to 62% (P < .001) following the intervention. Improvement was sustained 1-year post intervention (P < .001). A significant decrease in CDI was associated with the program. CONCLUSION: A novel program that addressed environmental services workers' knowledge gaps, challenges, and barriers was well received and appeared to result in learning, behavior change, and sustained improvements in cleaning.

Patient-Delivered Expedited Partner Therapy for Chlamydia trachomatis Infection Among Female Adolescents Using School-Based Health Centers.

INTRODUCTION: Expedited partner therapy (EPT) may reduce Chlamydia trachomatis reinfection. This pilot study was conducted to determine if female adolescents with C. trachomatis accept and deliver EPT to male sexual partners and whether it is associated with decreased C. trachomatis reinfection rates at 3 and 6 months. METHOD: Forty-six female adolescents, aged 13 to 19years and diagnosed with C. trachomatis at two urban school-based health centers, participated in four visits over 6 months. Participants completed a self-administered self-efficacy scale and a sexual risk behavior and EPT questionnaire and were retested for C. trachomatis 3 and 6 months after treatment. RESULTS: Overall, 65% accepted EPT, and 73% of those who accepted EPT delivered EPT to their partners. Eighty percent completed the 3-month visit, of these, 30% tested positive for C. trachomatis; 57% completed the 6-month visit, and of these, 15% tested positive for C. trachomatis. Acceptance of EPT was associated with reductions in C.trachomatis reinfection at 3 months (p = .04) but not at 6 months (p = .10). Delivery of EPT was not associated with reductions in C. trachomatis reinfection at 3 or 6 months (p = .08 and p = .44, respectively). Self-efficacy scales did not predict acceptance and delivery of EPT. DISCUSSION: Although two-thirds of participants accepted EPT and acceptance of EPT was associated with reductions in C. trachomatis reinfection at 3 months, rates of reinfection were high. Implications of these findings are limited by the small sample size. Larger studies are needed to understand potential barriers to delivery of EPT.

Comparing the Bioburden Measured by Adenosine Triphosphate (ATP) Luminescence Technology to Contact Plate-Based Microbiologic Sampling to Assess the Cleanliness of the Patient Care Environment.

The correlation between ATP concentration and bacterial burden in the patient care environment was assessed. These findings suggest that a correlation exists between ATP concentration and bacterial burden, and they generally support ATP technology manufacturer-recommended cutoff values. Despite relatively modest discriminative ability, this technology may serve as a useful proxy for cleanliness.Infect Control Hosp Epidemiol 2018;39:622-624.

Knowledge, Attitudes, and Practices Regarding Antimicrobial Use and Stewardship Among Prescribers at Acute-Care Hospitals.

OBJECTIVE To assess antimicrobial prescriber knowledge, attitudes, and practices (KAP) regarding antimicrobial stewardship (AS) and associated barriers to optimal prescribing. DESIGN Cross-sectional survey. SETTING Online survey. PARTICIPANTS A convenience sample of 2,900 US antimicrobial prescribers at 5 acute-care hospitals within a hospital network. INTERVENTION The following characteristics were assessed with an anonymous, online survey in February 2015: attitudes and practices related to antimicrobial resistance, AS programs, and institutional AS resources; antimicrobial prescribing and AS knowledge; and practices and confidence related to antimicrobial prescribing. RESULTS In total, 402 respondents completed the survey. Knowledge gaps were identified through case-based questions. Some respondents sometimes selected overly broad therapy for the susceptibilities given (29%) and some "usually" or "always" preferred using the most broad-spectrum empiric antimicrobials possible (32%). Nearly all (99%) reported reviewing antimicrobial appropriateness at 48-72 hours, but only 55% reported "always" doing so. Furthermore, 45% of respondents felt that they had not received adequate training regarding antimicrobial prescribing. Some respondents lacked confidence selecting empiric therapy using antibiograms (30%), interpreting susceptibility results (24%), de-escalating therapy (18%), and determining duration of therapy (31%). Postprescription review and feedback (PPRF) was the most commonly cited AS intervention (79%) with potential to improve patient care. CONCLUSIONS Barriers to appropriate antimicrobial selection and de-escalation of antimicrobial therapy were identified among front-line prescribers in acute-care hospitals. Prescribers desired more AS-related education and identified PPRF as the most helpful AS intervention to improve patient care. Educational interventions should be preceded by and tailored to local assessment of educational needs. Infect Control Hosp Epidemiol 2018;39:316-322.

Surgical Site Infections following Spine Surgery for Non-idiopathic Scoliosis.

BACKGROUND: Surgical site infections (SSIs) following spine surgery in children and adolescents with nonidiopathic scoliosis are associated with increased morbidity and health care costs. Potentially modifiable risk factors for SSIs merit additional study in this population. METHODS: A single-center, retrospective cohort study was performed from August 2008 through December 2013 in children and adolescents undergoing surgery for nonidiopathic scoliosis to determine the trends in SSI rate and causative microorganisms. A standardized perioperative antimicrobial prophylaxis regimen was developed from September-October 2008. Potential risk factors for SSIs were assessed by multivariable analysis using Poisson regression models. Fusion procedures and growing construct procedures were analyzed separately. RESULTS: In all, 268 patients underwent 536 surgical procedures of whom 192 underwent 228 fusion procedures, 89 underwent 308 growing construct procedures, and 13 underwent both procedures during the study period. Twenty-one SSIs (3.9% of surgical procedures and 7.8% of patients) occurred within 90 days of surgery, 17 SSIs occurred after fusion procedures (4.5% of procedures and 8.9% of patients), and 4 SSIs occurred after growing construct procedures (1.3% of procedures and 4.5% of patients). There were 9 polymicrobial SSIs (42.9%). Of the 31 bacterial pathogens isolated, 48% were Gram-negative organisms. Among patients undergoing fusion procedures, SSIs were associated with underdosing of preoperative cefazolin [relative risk (RR)=4.99; 95% confidence interval (CI), 1.89-17.43; P=0.012] and tobramycin (RR=5.86; 95% CI, 1.90-18.06; P=0.002), underdosing of intraoperative (RR=5.65; 95% CI, 2.13-14.97; P=0.001) and postoperative (RR=3.86; 95% CI, 1.20-12.40; P=0.023) tobramycin, and any preoperative or intraoperative underdosing (RR=4.89; 95% CI, 1.70-14.12; P=0.003), after adjustment for duration of surgery. No factors were associated with SSIs in those undergoing growing construct procedures. During the study period, the SSIs rate declined (P<0.0001). CONCLUSIONS: Underdosing of tobramycin and preoperative cefazolin were associated with an increased SSI risk among patients undergoing fusion procedures. Future multicenter studies should further investigate the generalizability of these findings. LEVEL OF EVIDENCE: Level II-retrospective study.

Understanding Barriers to Optimal Cleaning and Disinfection in Hospitals: A Knowledge, Attitudes, and Practices Survey of Environmental Services Workers.

In this study, we used an online survey to assess knowledge, attitudes, and practices related to environmental cleaning and other infection prevention strategies among environmental services workers (ESWs) at 5 hospitals. Our findings suggest that ESWs could benefit from additional education and feedback as well as new strategies to address workflow challenges. Infect Control Hosp Epidemiol 2016;1492-1495.

Improving case finding of invasive aspergillosis in children using string searches.

Surveillance for invasive Aspergillus (IA) in children is complex. We performed a retrospective study (2004-2013) using string searches of relevant terms within histopathology and radiology reports in efforts to improve detection of IA. Overall, 22 children met IA criteria, of whom 5 (23%) were only identified by string searches.

Changing Epidemiology of the Respiratory Bacteriology of Patients With Cystic Fibrosis.

BACKGROUND: Monitoring potential changes in the epidemiology of cystic fibrosis (CF) pathogens furthers our understanding of the potential impact of interventions. METHODS: We performed a retrospective analysis using data reported to the Cystic Fibrosis Foundation Patient Registry (CFFPR) from 2006 to 2012 to determine the annual percent changes in the prevalence and incidence of selected CF pathogens. Pathogens included Pseudomonas aeruginosa, methicillin-susceptible Staphylococcus aureus (MSSA), methicillin-resistant S aureus (MRSA), Haemophilus influenzae, Burkholderia cepacia complex, Stenotrophomonas maltophilia, and Achromobacter xylosoxidans. Changes in nontuberculous mycobacteria (NTM) prevalence were assessed from 2010 to 2012, when the CFFPR collected NTM species. RESULTS: In 2012, the pathogens of highest prevalence and incidence were MSSA and P aeruginosa, followed by MRSA. The prevalence of A xylosoxidans and B cepacia complex were relatively low. From 2006 to 2012, the annual percent change in overall (as well as in most age strata) prevalence and incidence significantly decreased for P aeruginosa and B cepacia complex, but significantly increased for MRSA. From 2010 to 2012, the annual percent change in overall prevalence of NTM and Mycobaterium avium complex increased. CONCLUSIONS: The epidemiology of CF pathogens continues to change. The causes of these observations are most likely multifactorial and include improvements in clinical care and infection prevention and control. Data from this study will be useful to evaluate the impact of new therapies on CF microbiology.
