Analysis of health care facility-onset Clostridioides difficile infection (CDI) in a hematopoietic cell transplant (HCT) unit: A call for diagnostic stewardship in a complex patient population

Nearly half the patients identified as having health care facility-onset Clostridioides difficile infections on a hematopoietic cell transplant unit had an alternative clinical explanation for diarrhea, including conditioning regimen toxicity or other medications. Our study supports that targeted diagnostic stewardship interventions should be explored and that additional risk-adjustments considered for facilities with oncology hematopoietic cell transplant wards in the National Healthcare Safety Network LabID Clostridioides difficile infection standardized infection ratio model.

Health care-associated Clostridioides difficile infection: Learning the perspectives of health care workers to build successful strategies

BACKGROUND

Clostridioides difficile (C difficile) is one of the most common health care-associated infections that negatively impact patient care and health care costs. This study takes a unique approach to C difficile infection (CDI) control by investigating key prevention obstacles through the perspectives of Stanford health care (SHC) frontline health care personnel.

METHODS

An anonymous qualitative survey was distributed at SHC, focusing on knowledge and practice of CDI prevention guidelines, as well as education, communication, and perspectives regarding CDI at SHC.

RESULTS

112 survey responses were analyzed. Our findings unveiled gaps in personnel's knowledge of C difficile diagnostic guidelines and revealed a need for targeted communication and guideline-focused education. Health care staff shared preferences and recommendations, with the majority recommending enhanced communication of guidelines and information as a strategy for reducing CDI rates. The findings were then used to design and propose internal recommendations for SHC to mitigate the gaps found.

DISCUSSION

Many guidelines and improvement strategies are based on strong scientific and medical foundations; however, it is important to ask whether these guidelines are effectively translated into practice. Frontline health care workers hold empirical perspectives that could be key in infection control.

CONCLUSIONS

Our findings emphasize the importance of including frontline health care personnel in infection prevention decision-making processes and the strategies presented here can be applied to mitigating infections in different health care settings.

Understanding the significance of microbiota recovered from health care surfaces

BACKGROUND

Microbial contamination of hospital surfaces remains despite adherence to routine disinfection. Our study demonstrates bioburden from various types of hospital high-touch surfaces and the pathogenicity of all bacteria recovered.

METHODS

Several high-touch hospital surfaces from a single medical-surgical unit were sampled and cultured using replicate organism detection and counting (RODAC) Tryptic Soy agar plates. Colonies were then subcultured to blood agar plates and speciated using MALDI-TOF. The local microbiology laboratory database was queried for any clinical isolate match with the environmental samples recovered.

RESULTS

Manikins, bed rails, and workstations-on-wheels were the most contaminated surfaces with the largest variety of bacteria isolated from manikins and bed rails. A total of 60 different types of pathogens were isolated, 18 of which were well-known pathogens, and 7 were classified as important in the health care setting by CDC. Our clinical microbiology laboratory identified 29 of 60 hospital surface bacteria in clinical isolates. Urine, soft tissue, and blood were the most common sources of clinical isolates.

CONCLUSIONS

Surfaces in the health care environment harbor both well-known and not-so-well-known human pathogens. Several not-so-well-known pathogens are skin flora or environmental bacteria, which in the right setting, can become pathogenic and cause diseases including meningitis, brain abscess, endocarditis, and bacteremia.

Personal stethoscope disinfection practices and bacterial contamination: A cross-sectional study at the University Hospital Emergency Department in Belgrade, Serbia

BACKGROUND

A significant reduction in bacterial growth on stethoscope membranes has been noticed after performing daily disinfection. Nevertheless, disinfection is rarely performed. We aimed to assess self-reported stethoscope disinfection practices among medical doctors, detect bacterial contamination on personal stethoscopes, and estimate the effectiveness of 70% ethanol as a stethoscope disinfecting agent.

METHODS

To determine stethoscope disinfection practices, participants filled out a questionnaire (N = 47), followed by providing stethoscopes for bacterial analysis. Differences in bacterial contamination were observed through the self-reported frequency and method of stethoscope disinfection. The effect of disinfecting with 70% ethanol was evaluated by comparing the presence of bacterial growth before and after disinfection.

RESULTS

The presence of bacterial growth was found in 78.7% of the stethoscope samples, with the median (interquartile range) number of colony-forming units at 25 (10-105). The frequency of disinfection greatly impacted the number of colony-forming units, and the method affected the presence of bacterial growth. Disinfection of stethoscope membranes using 70% ethanol resulted in a compelling 97.3% reduction of bacterial growth.

CONCLUSIONS

Adequate stethoscope disinfection is highly efficient in reducing bacterial contamination and as such should be considered a critical step in hygienic practices.

A narrative review of how infection preventionist (IP) staffing and outcome metrics are assessed by health care organizations and factors to consider

BACKGROUND

Infection Preventionist to date are experiencing staffing shortages, the purpose of this narrative review is to understand how heath care organizations track staffing and outcome metrics in relation to Infection Preventionists.

METHODS

Databases utilized included MEDLINE, PubMed, EMBASE, Web of Science, and Google Scholar.

RESULTS

The initial search included 668 studies. After excluding duplicates, the title and abstract review yielded 50 articles. After screening full texts, 37 studies met the inclusion criteria. Significant variability exists within infection prevention staffing metrics. Common metrics to account for IP staffing levels include the ratio of IPs per facility and IPs per inpatient bed. Frequently tracked outcomes in relation to infection preventionists include Catheter-associated urinary tract infections and central line bloodstream infection incidence rates and standardized infection ratios, as well as Clostridioides difficile incidence rates. Metrics and outcomes from included studies are available in our supporting tables.

CONCLUSIONS

This review highlights the need for a new IP staffing model that focuses on a granular assessment of each program and care setting. Additional studies can then be conducted to examine how ideal staffing impacts outcome metrics.

Impact of multimodal interventions targeting behavior change on hand hygiene adherence in nursing homes: An 18-month quasi-experimental study

BACKGROUND

Nursing home residents are vulnerable and frail, and hand hygiene adherence is often too low to prevent transmission of infections. This study's aim was to investigate whether interventions targeting behavior change can improve hand hygiene adherence in nursing homes.

METHODS

Over 18 months, 22 nursing home wards participated in this quasi-experimental study. Three intervention wards were selected based on the mean values of hand hygiene adherence, infections, and antibiotic use. Multimodal interventions targeting behavior change, including education, UV-light boxes, and posters, were implemented.

RESULTS

Hand hygiene adherence increased to 60.9% in the intervention wards and decreased to 51.3% in the control wards. The control wards experienced lower adherence in all indications of WHO's "My five moments for hand hygiene."

DISCUSSION

Interventions should target proper hand hygiene before patient contact and glove use because health care workers have low adherence in these areas. The findings indicate that the type of intervention is less important than attention to hand hygiene and activating workers' motivation. Using a behavior change approach and continuous reinforcement is important because the effects of interventions diminish over time.

CONCLUSIONS

Our findings showed that multimodal interventions targeting behavior change may increase hand hygiene adherence.

Voices from frontline nurses on care quality and patient safety during COVID-19: An application of the Donabedian model

BACKGROUND

The COVID-19 pandemic has adversely impacted quality of care and patient safety. This study aimed to describe registered nurses' (RNs) perceptions on the impact of the COVID-19 pandemic on their ability to adhere to patient safety protocols using Donabedian's Health Care Quality model.

METHODS

In October 2020, a survey was conducted among all actively licensed RNs in New Jersey who provided direct patient care during the first peak of COVID-19.

RESULTS

Of 3,027 participants, 68% reported that the number of patients assigned impacted their ability to adhere to protocols. RNs identified a variety of organizational structures impacting adherence, including inadequate staffing, staff qualifications, and inadequate resources. Impacted processes included the inability to adhere to patient safety protocols and conduct comprehensive assessments and surveillance, the need for additional time spent on personal protective equipment and isolation policies, and difficulty maintaining isolation integrity; the need to prioritize and cluster care; and guidelines limiting personnel who could enter the room. Nurses attributed both adverse patient and staff outcomes to inadequate staffing and high patient acuity.

CONCLUSIONS

These findings highlight the need for health care organizations to support frontline nursing staff in adhering to patient safety and infection prevention and control protocols during times of crises. Infection preventionists have substantial contact with bedside nurses and should leverage their collegial relationships to promote patient safety.

Efficacy of a filtered far-UVC handheld disinfection device in reducing the microbial bioburden of hospital surfaces

BACKGROUND

The filtered far-UV-C (FFUV) handheld disinfection device is a small portable device that emits far UV-C at 222 nm. The objective of this study was to evaluate the device's ability to kill microbial pathogens on hospital surfaces and compare it to manual disinfection using germicidal sodium hypochlorite wipes.

METHODS

A total of 344 observations (4 observations from 86 objects' surfaces) were sampled with 2 paired samples per surface: a pre- and a post-sodium hypochlorite and FFUV sample. The results were analyzed via a Bayesian multilevel negative binomial regression model.

RESULTS

The estimated mean colony counts for the sodium hypochlorite control and treatment groups were 20.5 (95% uncertainty interval: 11.7-36.0) and 0.1 (0.0-0.2) colony forming units (CFUs), respectively. The FFUV control and treatment groups had mean colony counts of 22.2 (12.5-40.1) and 4.1 (2.3-7.2) CFUs. The sodium hypochlorite group and the FFUV group had an estimated 99.4% (99.0%-99.7%) and 81.4% (76.2%-85.7%) reduction in colony counts, respectively.

CONCLUSIONS

The FFUV handheld device effectively reduced the microbial bioburden on surfaces in the health care setting. The major benefit of FFUV is likely seen when manual disinfection is not possible or when supplementing cleaners or disinfectants with the low-level disinfection properties.

Health Care-Associated Infection in Elderly Patients With Cerebrovascular Disease in Intensive Care Units: A Retrospective Cohort Study in Taizhou, China

BACKGROUND

Cerebrovascular diseases are associated with high incidence of health care-associated infections (HAIs) and poor prognosis in elderly patients. This study aimed to investigate the incidence and clinical characteristics of HAIs in elderly patients with cerebrovascular disease in the intensive care unit (ICU).

METHODS

Patients admitted with cerebrovascular disease, aged ≥65 years, were included. The clinical data of the patients were retrospectively analyzed to determine the risk factors, infection type, distribution, and pathogenic characteristics of HAIs in the context of cerebrovascular diseases.

RESULTS

Out of 381 ICU inpatients monitored, 79 (20.73%) developed HAIs. Risk analysis revealed number of ventilator days as significant risk factors for HAIs in elderly patients with cerebrovascular diseases in the comprehensive ICU. In the HAI group, 56 patients (70.89%) had respiratory tract infection (RTI). Sixty-five patients (82.28%) were infected with Gram-negative bacteria (GNB), and 42 (53.16%) with multi-drug-resistant organism (MDRO). The length of hospitalization days, ventilator days, and overall hospitalization costs were higher in the HAI group than in the non-HAI group (P < 0.05), but there was no significant difference between groups in the treatment outcome of patients. Patients with MDRO infection had longer duration and higher cost of hospitalization than those infected with non-MDRO (P < 0.05), but there was no significant difference between the groups in the treatment outcome of patients.

CONCLUSIONS

HAIs occurred mostly due to RTI and GNB infection. The hospitalization cost and duration, as well as the length of ventilator days, were higher for cerebrovascular patients with HAIs than for non-HAIs patients.

Infection Prevention in the Neonatal Intensive Care Unit

Although many aspects of infection prevention and control (IPC) mirror institutional efforts, optimization of IPC practices in the neonatal intensive care unit requires careful consideration of its unique population and environment, addressed here for key IPC domains. In addition, innovative mitigation efforts to address challenges specific to limited resource settings are discussed.

Surface sampling within a pediatric ward-how multiple factors affect cleaning efficacy

BACKGROUND

The objectives of this study were to assess the number of organisms present on different surfaces within a clinical environment before and after cleaning took place, and to identify the impact of cleaning. The study involved extensive 2-week microbiological environmental monitoring of an entire ward before and after cleaning; the ward was located within a pediatric hematology-oncology ward comprised of a day unit and outpatient ward.

METHODS

Tryptone soya agar contact plates were used to take a total of 1,160 surface samples before and after cleaning from 55 predetermined sites. Samples were taken from representative surfaces throughout the ward representing a variety of materials, surface heights, functions, and distances from patients, as well as both high-touch and infrequently touched surfaces.

RESULTS

After surface cleaning was undertaken within the ward, there was a significant difference between the amount of colony-forming units (CFUs) recovered before and after cleaning (P < .0001). Cleaning produced an average CFU reduction of 68% throughout the ward environment. The corridor was the most contaminated area within the ward. There were differences in the CFUs among the various areas within the ward, which were cleaned with varying efficiency. The surface material, who interacted with the surface, levels of initial contamination, perceived risk, and perceived cleanability were all found to have a varying impact on the cleaning effectiveness.

CONCLUSIONS

To the authors' current knowledge, this is the only study to assess cleaning within a pediatric ward by taking samples directly before and after cleaning. The standard of cleaning undertaken within the ward is open for discussion, and these data highlight the need for an improved cleaning intervention and can provide insight into the multitude of factors that must be considered when designing an effective training protocol.

Examining the inclusion of patients and their family members in infection prevention and control policies and guidelines across Bangladesh, Indonesia, and South Korea

BACKGROUND

Although familial involvement during inpatient care is not uncommon in western countries, the types of caring activities that family members in Asian countries provide are significantly different. These activities may place the family member at risk from a health care-associated infection. This study aimed to examine whether the role of patients' families has been accounted for in the infection prevention and control (IPC) guidelines and policy, using examples from Bangladesh (low-income country), Indonesia (middle-income country), and South Korea (high-income country).

METHODS

The World Health Organization website and Institutional Repository for Information Sharing, Centers for Disease Control and Prevention website, Australian Government Web Archive, Open Grey, Grey Matters, World Bank, and advanced Google search, as well as the Health Department/Ministry of Health websites for each target country and 4 western countries (Australia, Canada, England, and the United States) were searched. Other databases, such as Embase, Medline, CINAHL, Global Health, ProQuest databases, Google scholar, Web of Science, and Scopus were also searched. This was to review the reflection of the cultural influence in IPC policies/guidelines by reviewing those from the global organizations, which are often used as a blueprint for policy development, as well as those from western countries, which hold different cultures in care arrangement. Search was conducted with attention to the key areas: definition and role of carer in the acute health care facility, involvement of patients/family members in IPC activities, patient and family member hand hygiene, and IPC education.

RESULTS

Ninety-two articles were identified based on the criteria for the study. Only 6 acknowledged that care is provided to hospitalized patients by their family members, and only 1 recommended that family members receive the same level of training as health care workers on IPC precautions. Other guides recommended the provision of information on IPC measures as means of patient involvement in the IPC program. Recognition of family caregivers or inclusion of them in the IPC strategies was not included in the target countries' guidelines.

CONCLUSIONS

Although health care workers are the primary actors when it comes to providing care in acute health care settings, it is important to expand the IPC guides by considering the role of other caregivers. Policies and guidelines should reflect the cultural influence over healthcare. This is especially true when cultural values strongly influence over healthcare arrangements and the healthcare accommodates these cultural influences in the practice. Further work needs to be undertaken on the level of training/education provided to family members in Bangladesh, Indonesia, and South Korea.

Discourse on hygiene between hospitalized patients and health care workers as an accepted norm: Making it legitimate to remind health care workers about hand hygiene

BACKGROUND

Despite World Health Organization recommendations that patients should play a role in encouraging hand hygiene (HH) as a means of preventing infection, patient engagement remains an underused method. From the perspectives of hospitalized patients (HPs) and health care workers (HCWs) at 2 major public hospitals in Haifa, Israel, this research investigated (1) HP barriers to reminding HCWs to maintain HH, (2) HCW barriers to giving HPs instruction on proper hygiene, (3) what could help HPs and HCWs overcome these barriers, and (4) how video clips can be used to devise tailored strategies governing discourse on HH between HCWs and HPs.

METHODS

Intervention type 2 design and examination of 2 population groups-HPs and HCWs-before and after intervention by means of mixed methods research.

RESULTS

Both HPs and HCWs reported partial knowledge, embarrassment, and fears regarding commenting to staff, as well as a lack of cultural adaptation. The interviewees indicated that the video clips granted legitimacy to reminding HCWs about hygiene through strategies designed to identify and solve barriers, authenticity, and cultural adaptation.

CONCLUSIONS

To overcome HP and HCW barriers to maintaining HH, tailored video clips on HH should specify barriers and solutions with which they can both identify, thus turning discourse on HH into an accepted norm.

Hand hygiene compliance surveillance with time series anomaly detection

BACKGROUND

Hand hygiene is the most important intervention to reduce the risk of transmission of pathogens in health care. Assurance of effective hand hygiene improvement campaigns includes adequate data analytics for reporting compliance. Traditional analytical approaches for monitoring hand hygiene compliance suffer from several limitations, including autocorrelation. The objective of this study was to use a novel time series anomaly detection algorithm to analyze routine hand hygiene compliance data.

METHODS

Hand hygiene compliance data were collected daily by trained observers in a large academic medical center. Statistical process control p-charts were used as a comparison method of analysis per facility protocol. Time series anomaly detection was carried out using the seasonal and trend decomposition using LOESS (STL) algorithm.

RESULTS

A total of 34 months of hand hygiene compliance data were analyzed. Traditional statistical process control p-charts identified over 76% of rates as special-cause variation, whereas STL identified 18% of rates as anomalous.

CONCLUSIONS

This study supports the use of time series anomaly detection for the routine surveillance of hand hygiene compliance data. This method will facilitate specific and accurate feedback, helping to improve this critical approach for improving patient safety.

Skin colonization at peripheral intravenous catheter insertion sites increases the risk of catheter colonization and infection

BACKGROUND

Peripheral intravenous catheters (PIVCs) break the skin barrier, and preinsertion antiseptic disinfection and sterile dressings are used to reduce risk of catheter-related bloodstream infection (CRBSI). In this study, the impact of PIVC skin site colonization on tip colonization and the development of CRBSI was investigated.

METHODS

A total of 137 patients' PIVC skin site swabs and paired PIVC tips were collected at catheter removal, cultured, and bacterial species and clonality were identified.

RESULTS

Of 137 patients, 45 (33%) had colonized skin sites and/or PIVC tips. Of 16 patients with paired colonization of both the skin site and PIVC tips, 11 (69%) were colonized with the same bacterial species. Of these, 77% were clonally related, including 1 identical clone of Pseudomonas aeruginosa in a patient with systemic infection and the same organism identified in blood culture.

CONCLUSIONS

The results demonstrate that opportunistic pathogen colonization at the skin site poses a significant risk for PIVC colonization and CRBSI. Further research is needed to improve current preinsertion antiseptic disinfection of PIVC skin site and the sterile insertion procedure to potentially reduce PIVC colonization and infection risk.

Perceptions of Patients, Health Care Workers, and Environmental Services Staff Regarding Ultraviolet Light Room Decontamination Devices

BACKGROUND

Mobile ultraviolet C (UV-C) room decontamination devices are widely used in health care facilities; however, there is limited information on the perceptions of patients, health care workers (HCWs), and environmental services staff (EVS-staff) regarding their use for environmental decontamination.

METHODS

An anonymous questionnaire was administered to participants in 4 medical/surgical units of a tertiary care hospital where UV-C devices were deployed for a 6-month period. Survey questions assessed perceptions regarding the importance of environmental disinfection, effectiveness of UV-C decontamination, willingness to delay hospital admission in order to use UV-C, and safety of UV-C devices.

RESULTS

Questionnaires were completed by 102 patients, 130 HCWs, and 47 EVS-staff. All of the HCWs and EVS-staff and 99% of the patients agreed that environmental disinfection is important to reduce the risk of exposure from contaminated surfaces. Ninety-eight percent of the EVS-staff, 89% of the HCWs, and 96% of the patients felt that the use of UV-C as an adjunct to routine cleaning increased confidence that rooms are clean. Ninety-four percent of the EVS-staff, 85% of the HCWs, and 90% of the patients expressed a willingness to delay being admitted to a room in order to have UV-C decontamination completed. Seventy-nine percent of the EVS-staff, 76% of the HCWs, and 86% of the patients had no concerns about the safety of UV-C devices.

CONCLUSIONS

Patients, HCWs, and EVS-staff agreed that environmental disinfection is important and that UV-C devices are efficacious and safe. Educational tools are needed to allay safety concerns expressed by a minority of HCWs and EVS-staff.

Acinetobacter baumannii can be transferred from contaminated nitrile examination gloves to polypropylene plastic surfaces

BACKGROUND

Several observational studies suggest that gloves of health care workers are major routes of multidrug-resistant Acinetobacter baumannii transmission. However, limited experimental data are available assessing Acinetobacter transmission from gloves to environmental surfaces. This study determined whether A baumannii was easily transferred from nitrile gloves to polypropylene plastic compared with other gram-negative bacteria that cause health care-associated infections in laboratory-controlled experiments.

METHODS

Gloved fingerpad-to-fomite transfer efficiency was determined for drug-resistant and -sensitive strains of A baumannii, Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, and Pseudomonas aeruginosa.

RESULTS

Only A baumannii transferred from gloves to fomites 3 minutes after the bacterial transfer event. Transfer efficiency of A baumannii was 0.1%-33% at that time point.

DISCUSSION

Bacterial transfer from contaminated gloves to the hospital environment may be related to the type of contaminating bacteria, inoculated bacterial level, fomites, and glove materials. Therefore, it is important to need a comprehensive assessment of the transfer efficiency.

CONCLUSIONS

A baumannii can transfer easily from nitrile gloves to fomite compared with other gram-negative bacteria that cause health care-associated infections. These findings support data from previous observational studies that gloves of health care workers can be major routes of A baumannii transmission in clinical settings.

Survival of Staphylococcus aureus on therapeutic ultrasound heads

Therapeutic ultrasound (US) is commonly used in the rehabilitation of soft tissue injuries including wounds. US heads and coupling gel come into direct contact with patient skin, increasing the risk for health care-associated infections owing to cross contamination. In this study, nearly 80% of Staphylococcus aureus placed on US heads in gel survived for 1 hour, with survival of 3 days possible in other types of organic matter.

Outbreak investigation of Pseudomonas aeruginosa infections in a neonatal intensive care unit

A Pseudomonas aeruginosa outbreak was investigated in a neonatal intensive care unit that had experienced a prior similar outbreak. The 8 cases identified included 2 deaths. An investigation found the cause of the outbreak: tap water from contaminated hospital plumbing which was used for humidifier reservoirs, neonatal bathing, and nutritional preparation. Our findings reinforce a recent Centers for Medicare & Medicaid Services memo recommending increased attention to water management to improve awareness, identification, mitigation, and prevention of water-associated, health care-associated infections.

Simplifying Disinfectant Choices to Improve Safety in Contact Precaution Rooms

Both quaternary ammonium and bleach-based cleaning products are effective in reducing the transmission of methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus in hospitals, but bleach-based compounds demonstrate better control of Clostridium difficile infections. Our pilot study demonstrates the potential to reduce C. difficile transmission in an acute care hospital by eliminating the need for providers to choose the appropriate cleaning product from isolation precaution carts.

Bare below the elbows in an academic medical center

We investigated the compliance of health care personnel with a voluntary, institution-wide bare below the elbows (BBE) approach to inpatient care at an academic medical center. BBE compliance increased significantly across all provider types over a 2-year period. The overall compliance with BBE by health care personnel nearly doubled from 2016-2017, increasing significantly from 40% to 84%.

International responses to the 2015 APIC MegaSurvey

The prevention of health care-associated infections is an international concern. Infection preventionists across the world play a key role in assessing, planning, implementing, and evaluating infection control policies. In 2015, the APIC launched the MegaSurvey to establish the state of the infection preventionist workforce. This brief report will describe and compare responses from the United States, Canada, and "other" countries to establish a professional baseline and set an agenda for future international collaborations.

Impact of infectious exposures and outbreaks on nurse and infection preventionist workload

BACKGROUND

Staff nurse and infection preventionist (IP) workload increases in response to exposures and outbreaks. Understanding the time burden associated with responding to specific pathogens may improve resource allocation. The purpose of this study was to evaluate workload increases reported by nurses and IPs in response to common exposures and outbreaks.

METHODS

Surveys were distributed to nurses in a New York hospital network and to IPs who attended the 2018 Association for Professionals in Infection Control and Epidemiology annual conference or to IPs who were members of local Association for Professionals in Infection Control and Epidemiology chapters. Respondents were asked to rate their daily workload increase and to rank their most time-consuming activities in response to exposure and outbreak scenarios.

RESULTS

A total of 150 nurses and 228 IPs responded. Among the nurses, >60-minute workload increases were reported for Clostridium difficile (76%), lice or scabies (46%), and influenza (45%). Among the IPs, >60-minute increases were reported for mumps or measles (66%), tuberculosis (64%), and C difficile (50%). Among the nurses, isolation precautions, patient and family education, and staffing changes were the most frequently reported time-consuming activities. Among the IPs, chart review, exposure list compiling, and preventive measures for exposures were the most frequently reported time-consuming activities.

CONCLUSIONS

Organisms that are easier to treat and more difficult to spread, such as scabies or lice, can contribute substantially to nursing workload. Notably, three-quarters of the nurses and one-half of the IPs reported that C difficile adds >1 hour to their daily workload.

Current practice of infection control in Dutch primary care: Results of an online survey

BACKGROUND

Good infection prevention is an important aspect of quality of medical care. The aim was to evaluate infection prevention and control (IPC) performance among Dutch general practitioners (GPs).

METHODS

Based on the current national IPC guidelines for GPs, a self-administered anonymous online questionnaire was developed and sent to GPs in the Nijmegen region of the Netherlands. Thirty-two questions were constructed to survey characteristics of GPs' offices and assess current performance of IPC measures.

RESULTS

One hundred questionnaires were included in our analysis. The preferred method of hand hygiene was soap and water (56%) versus alcohol-based handrub (44%). The cleaning of nondisposable, noncritical, semicritical, and critical instruments was consistent with national guideline recommendations or superior to them in 100%, 49%, and 97% of cases, respectively. An average of 57% of GPs reported environmental cleaning frequencies that were compliant with the national guidelines or superior to them. Personal protective equipment was available in 62% of GPs' practices but used in only 25% of home visits to patients.

CONCLUSIONS

Not all national IPC guidelines seem to be followed to the fullest extent. The current situation indicates there is room for potential improvement regarding implementation of IPC measures in GPs' offices. Area-specific guidelines and continuous medical education regarding IPC may help improve the situation.

Nasal decolonization: What antimicrobials are most effective prior to surgery?

BACKGROUND

Surgical site infection (SSI) is one of the most common health care-associated infections. Staphylococcus aureus remains the most common etiologic agent causing SSIs. Studies confirm S aureus carriage increases the risk of S aureus SSIs. The purpose of this article is to review the strategies to reduce SSIs due to S aureus focusing on nasal decolonization.

RESULTS

Published studies indicate screening patients for S aureus nasal carriage and decolonizing carriers during the preoperative period decreases the risk of S aureus SSIs in cardiac and orthopedic surgery. Mupirocin remains the best topical agent at eradicating nasal S aureus however, concerns over resistance have led to development of alternative agents. Nasal povidone-iodine, alcohol-based nasal antiseptic, and photodynamic therapy are promising new interventions, but more studies are needed.

CONCLUSIONS

Short term nasal mupirocin is still the most studied and effective topical agent in eradicating S aureus nasal colonization. However, increasing mupirocin resistance remains an ongoing concern and newer agents are needed. Currently, preoperative S aureus decolonization often uses combination chlorhexidine gluconate bathing and nasal mupirocin considering that colonization of multiple body sites is commonly seen.

Beyond entry and exit: Hand hygiene at the bedside

BACKGROUND

We aimed to assess compliance, knowledge, and attitudes regarding the World Health Organization (WHO) 5 moments for hand hygiene (HH).

METHODS

We assessed HH compliance from July-August 2016, using a modified WHO HH observation form. A 26-question survey was used to assess health care personnel (HCP) knowledge, opinions, and barriers to HH. A subgroup of HCPs participated in a 2-round focused survey to assign priority to the moments.

RESULTS

Three hundred two HH opportunities were observed in 104 unique HCP-patient interactions. HH was performed at 106 (35%) opportunities, 37% (25 of 68) before touching a patient, 9% (6 of 70) before aseptic procedures, 5% (1 of 22) after body fluid exposure or risk, 63% (55 of 88) after touching a patient, and 35% (19 of 54) after touching patient surroundings. Two hundred eighteen HCPs completed the survey; 63 (29%) were familiar with the WHO 5 moments but only 13 (21%) were able to recall all 5 moments. In the focused surveys, 46% (6 of 13) ranked "before aseptic procedure" as the most important HH moment, and 86% (11 of 13) identified "after touching patient surroundings" as the least important.

CONCLUSIONS

We found frequent opportunities for HH with infrequent compliance. Lack of recognition of opportunities at the bedside and frequent glove use may contribute to lower compliance.

Perceived impact of state-mandated reporting on infection prevention and control departments

BACKGROUND

Currently, most US states have adopted legislation requiring hospitals to submit health care-associated infection (HAI) data. We evaluated the perceived impact of state HAI laws on infection prevention and control (IPC) departments.

METHODS

A web-based survey of a national sample of all non-veteran hospitals enrolled in the National Healthcare Safety Network was conducted in fall 2011. Variations in IPC department resources and characteristics in states with and without laws were compared by use of χ², Mann-Whitney (Wilcoxon), and Student t tests. Multinomial logistic regression was used to identify increases or decreases, versus no change, in perceived resources, time, influence, and visibility of the IPC department in states with and without HAI laws.

RESULTS

Overall, 1,036 IPC departments provided complete data (30% response rate); 755 (73%) were located in states with laws. Respondents in states with reporting laws were more likely to report less time for routine IPC activities (odds ratio, 1.61; 95% confidence interval, 1.12-2.31) and less visibility of the IPC department (odds ratio, 1.70; 95% confidence interval, 1.12-2.58) than respondents in states without laws, after controlling for geographic region, setting, and the presence of a hospital epidemiologist.

CONCLUSIONS

Respondents in states with laws reported negative effects on their IPC department, beyond what was required by federal mandates. Further research should examine resources necessary to comply with state HAI laws and evaluate unintended consequences of state HAI laws.

Efficacy and safety of a novel skin cleansing formulation versus chlorhexidine gluconate

BACKGROUND

This study evaluated whether a multi-ingredient surfactant colloidal silver technology was noninferior to a 4% chlorhexidine gluconate (CHG) antiseptic on immediate and persistent antimicrobial activity.

METHODS

The inguinal regions of 81 healthy adults were demarcated into 4 quadrants, and 3 were used for testing each product at baseline, 10 minutes, and 6 hours postapplication. The log of the number of colony forming units was obtained using a cylinder sampling technique. The 95% confidence interval of the test product to the control product with a margin of 0.65 was established as the upper limit of noninferiority.

RESULTS

A total of 81 individuals were enrolled. The colloidal silver product was found to be noninferior to 4% CHG at both 10 minutes and 6 hours postapplication.

CONCLUSIONS

The colloidal silver-based product was noninferior to the 4% CHG product at 10 minutes and 6 hours postapplication.

A multistate investigation of health care-associated Burkholderia cepacia complex infections related to liquid docusate sodium contamination, January-October 2016

BACKGROUND

Outbreaks of health care-associated infections (HAIs) caused by Burkholderia cepacia complex (Bcc) have been associated with medical devices and water-based products. Water is the most common raw ingredient in nonsterile liquid drugs, and the significance of organisms recovered from microbiologic testing during manufacturing is assessed using a risk-based approach. This incident demonstrates that lapses in manufacturing practices and quality control of nonsterile liquid drugs can have serious unintended consequences.

METHODS

An epidemiologic and laboratory investigation of clusters of Bcc HAIs that occurred among critically ill, hospitalized, adult and pediatric patients was performed between January 1, 2016, and October 31, 2016.

RESULTS

One hundred and eight case patients with Bcc infections at a variety of body sites were identified in 12 states. Two distinct strains of Bcc were obtained from patient clinical cultures. These strains were found to be indistinguishable or closely related to 2 strains of Bcc obtained from cultures of water used in the production of liquid docusate, and product that had been released to the market by manufacturer X.

CONCLUSIONS

This investigation highlights the ability of bacteria present in nonsterile, liquid drugs to cause infections or colonization among susceptible patients. Prompt reporting and thorough investigation of potentially related infections may assist public health officials in identifying and removing contaminated products from the market when lapses in manufacturing occur.

Evaluation of hospital-grade disinfectants on viral deposition on surfaces after toilet flushing

BACKGROUND

Past studies have shown that infectious aerosols created during toilet flushing result in surface contamination of the restroom. The goals of this study were to quantify viral contamination of surfaces in restrooms after flushing and the impact of disinfectants added to the toilet bowl prior to flushing on reducing surface contamination.

METHODS

The degree of contamination of surfaces in the restroom was assessed with and without the addition of coliphage MS2 to the toilet bowl before flushing. The bowl water and various surfaces in the restroom were subsequently tested for the presence of the virus.

RESULTS

The toilet bowl rim, toilet seat top, and toilet seat underside were contaminated in all trials without a disinfectant added to the bowl water before flushing. All disinfectants significantly reduced concentrations on surfaces when the contact time was ≥15 minutes. Hydrogen peroxide resulted in very little reduction of virus in the toilet bowl (<1 log₁₀). Peracetic acid and quaternary ammonium had the greatest log reductions on virus in the organic matter in the toilet.

CONCLUSIONS

Toilet flushing resulted in extensive contamination of surfaces within the restroom. Addition of disinfectant to the toilet bowl prior to flushing reduced the level of contamination in the bowl and fomites after flushing.

Evaluating the direct economic burden of health care-associated infections among patients with colorectal cancer surgery in China

BACKGROUND

Little is known about the direct economic burden associated with health care-associated infection (HAI) in patients undergoing colorectal cancer surgery in China. This study aims to fill this knowledge gap.

METHODS

This study was a prospective monitoring case-control study. The direct economic burden was presented as the median of the 1:1 pair differences of various hospitalization fees and hospital length of stay. Wilcoxon signed-rank tests were used to explore the differences in the direct economic burden.

RESULTS

Out of 448 patients, 38 had acquired HAIs, with the infection incidence being 8.93%. The total direct economic burden of HAIs was $1,589.30 (P <.05). Among various infection sites, deep surgical site infection had the highest direct economic burden of $8,654.44, followed by multisite infections ($5,946.52). When it comes to various hospitalization costs, the cost for Western medicine ($846.13) constituted the highest proportion of economic burden followed by treatment cost ($145.73) and bed charge ($126.75). On average, the length of hospital stay in the infection group was 6 days longer than that in the control group (P <.05).

CONCLUSIONS

HAI was associated with considerable economic burden for patients who underwent colorectal cancer surgery in China. The study highlights the necessity of taking effective measures to decrease incidence of HAIs to reduce economic burden.

Risk factors for health care-associated infection in hospitalized adults: Systematic review and meta-analysis

BACKGROUND

Health care-associated infections (HAIs) are a public health problem that increase health care costs. This article aimed to systematically review the literature and meta-analyze studies investigating risk factors (RFs) independently associated with HAIs in hospitalized adults.

METHODS

Electronic databases (MEDLINE, Embase, and LILACS) were searched to identify studies from 2009-2016. Pooled risk ratios (RRs) or odds ratios (ORs) or mean differences (MDs) and 95% confidence intervals (CIs) were calculated and compared across the groups. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

RESULTS

Of 867 studies, 65 met the criteria for review, and the data of 18 were summarized in the meta-analysis. The major RFs independently associated with HAIs were diabetes mellitus (RR, 1.76; 95% CI, 1.27-2.44), immunosuppression (RR, 1.24; 95% CI, 1.04-1.47), body temperature (MD, 0.62; 95% CI, 0.41-0.83), surgery time in minutes (MD, 34.53; 95% CI, 22.17-46.89), reoperation (RR, 7.94; 95% CI, 5.49-11.48), cephalosporin exposure (RR, 1.77; 95% CI, 1.30-2.42), days of exposure to central venous catheter (MD, 5.20; 95% CI, 4.91-5.48), intensive care unit (ICU) admission (RR, 3.76; 95% CI, 1.79-7.92), ICU stay in days (MD, 21.30; 95% CI, 19.81-22.79), and mechanical ventilation (OR, 12.95; 95% CI, 6.28-26.73).

CONCLUSIONS

Identifying RFs that contribute to develop HAIs may support the implementation of strategies for their prevention, therefore maximizing patient safety.

Effects of contact time and concentration on bactericidal efficacy of 3 disinfectants on hard nonporous surfaces

This study investigated the influence of contact time and concentration on bactericidal efficacy of 3 types of disinfectants (accelerated hydrogen peroxide [AHP], quaternary ammonium compounds [Quats], and sodium hypochlorite) on stainless steel surfaces using Environmental Protection Agency procedure MB-25-02. We found that bactericidal efficacy was not reduced at contact times or concentrations immediate lower than label use values, but all 3 disinfectants were significantly less bactericidal at significantly lower than label use contact times and concentrations. Overall, the bactericidal efficacy of the sodium hypochlorite disinfectant was most tolerant to the decreases of contact times and concentrations, followed closely by AHP disinfectant, and Quat disinfectant was most affected by contact time and concentration.

Health care worker perspectives of their motivation to reduce health care-associated infections

BACKGROUND

Health care-associated infections (HAIs) are largely preventable, but are associated with considerable health care burden. Given the significant cost of HAIs, many health care institutions have implemented bundled interventions to reduce HAIs. These complex behavioral interventions require considerable effort; however, individual behaviors and motivations crucial to successful and sustained implementation have not been adequately assessed. We evaluated health care worker motivations to reduce HAIs.

METHODS

This was a phenomenologic qualitative study of health care workers in different roles within a university hospital, recruited via a snowball strategy. Using constructs from the Consolidated Framework for Implementation Research model, face-to-face semi-structured interviews were used to explore perceptions of health care worker motivation to follow protocols on HAI prevention.

RESULTS

Across all types of health care workers interviewed, patient safety and improvement in clinical outcomes were the major motivators to reducing HAIs. Other important motivators included collaborative environment that valued individual input, transparency and feedback at both organizational and individual levels, leadership involvement, and refresher trainings and workshops. We did not find policy, regulatory considerations, or financial penalties to be important motivators.

CONCLUSIONS

Health care workers perceived patient safety and clinical outcomes as the primary motivators to reduce HAI. Leadership engagement and data-driven interventions with frequent performance feedback were also identified as important facilitators of HAI prevention.

Risk factors for health care-associated infections: From better knowledge to better prevention

BACKGROUND

Health care-associated infections (HCAIs) are preventable with adoption of recognized preventive measures. The first step is to identify patients at higher risk of HCAI. This study aimed to identify patient risk factors (RFs) present on admission and acquired during inpatient stay which could be associated with higher risk of acquiring HCAI.

METHODS

A case-control study was conducted in adult patients admitted during 2011 who were hospitalized for >48 hours. Cases were patients with HCAIs. Controls were selected in a ratio of 3:1, case matched by the admission date. The likelihood of increased HCAI was determined through binary logistic regression.

RESULTS

RFs identified as being the more relevant for HCAI were being a man (odds ratio [OR], 2.4; 95% confidence interval [CI], 1.2-4.7), being aged >50 years (OR, 2.9; 95% CI, 1.3-6.9), and having an insertion of a central venous line during hospital stay (OR, 12.4; 95% CI, 5.0-30.5).

CONCLUSIONS

RFs that showed statistical significance on admission were the patient's intrinsic factors, and RFs acquired during hospitalization were extrinsic RFs. When a set of RFs were present, the presence of a central venous line proved to be the more relevant one.

Knowledge, attitudes, and practices regarding environmental cleaning among environmental service workers in Chinese hospitals

We conducted a study using a face-to-face survey to assess knowledge, attitudes, and practices of environmental service workers (ESWs) concerning routine cleaning and disinfection at 3 tertiary hospitals in China. There were 115 (89.1%) respondents who agreed that environmental cleaning can contribute to keep patients safe, whereas 63 (48.8%) reported they were very willing to make cleaning practices better. Only 15 (11.6%) ESWs agreed they were in risk of nosocomial infections during daily cleaning. Our findings suggest that the level of ESWs' knowledge regarding cleaning practices was passable, but the awareness of occupational safety and health was weak. There is a need to introduce sustained education and training aimed at ESWs.

Systems-based Practice in Burn Care: Prevention, Management, and Economic Impact of Health Care-associated Infections

Health care-associated infections in burn patients, from ventilator-associated pneumonia to skin and soft tissue infections, can substantially compromise outcomes, because these complications are associated with longer lengths of stay, increased morbidity and mortality, and greater direct medical costs. Health care-associated infections are largely preventable, through surveillance, education, appropriate hand hygiene, and culture change, especially for device-related infections. Systems-based practice, which allows individuals and clinical microsystems to navigate and improve the macro health care system, may be one of the most powerful skill sets to effect change, permitting a shift in culture toward patient safety and quality improvement.

Antimicrobial copper alloys decreased bacteria on stethoscope surfaces

BACKGROUND

Stethoscopes may serve as vehicles for transmission of bacteria among patients. The aim of this study was to assess the efficacy of antimicrobial copper surfaces to reduce the bacterial concentration associated with stethoscope surfaces.

METHODS

A structured prospective trial involving 21 health care providers was conducted at a pediatric emergency division (ED) (n = 14) and an adult medical intensive care unit located in tertiary care facilities (n = 7). Four surfaces common to a stethoscope and a facsimile instrument fabricated from U.S. Environmental Protection Agency-registered antimicrobial copper alloys (AMCus) were assessed for total aerobic colony counts (ACCs), methicillin-resistant Staphylococcus aureus, gram-negative bacteria, and vancomycin-resistant enterococci for 90 days.

RESULTS

The mean ACCs collectively recovered from all stethoscope surfaces fabricated from the AMCus were found to carry significantly lower concentrations of bacteria (pediatric ED, 11.7 vs 127.1 colony forming units [CFU]/cm², P < .00001) than their control equivalents. This observation was independent of health care provider or infection control practices. Absence of recovery of bacteria from the AMCu surfaces (66.3%) was significantly higher (P < .00001) than the control surfaces (22.4%). The urethane rim common to the stethoscopes was the most heavily burdened surface; mean concentrations exceeded the health care-associated infection acquisition concentration (5 CFU/cm²) by at least 25×, supporting that the stethoscope warrants consideration in plans mitigating microbial cross-transmission during patient care.

CONCLUSIONS

Stethoscope surfaces fabricated with AMCus were consistently found to harbor fewer bacteria.

Life-threatening Skin Disorders Treated in the Burn Center: Impact of Health care-associated Infections on Length of Stay, Survival, and Hospital Charges

This article reviews a single burn center experience with life-threatening skin disorders, over a 10-year period. It explores the incidence of health care-associated infections and the impact on length of stay, hospital charges, and mortality.

Skin antisepsis with chlorhexidine versus iodine for the prevention of surgical site infection: A systematic review and meta-analysis

BACKGROUND

Surgical site infection (SSI) is one of the most frequent health care-associated infections. One of the practices to reduce their incidence is preoperative skin antisepsis. Two of the most commonly active components used are chlorhexidine gluconate and povidone iodine. Of 3 reviews conducted between 2010 and 2012 comparing antiseptics, 2 were in favor of chlorhexidine; however, the latest was unable to draw conclusions.

PURPOSE

To verify whether recent evidence supports the hypothesis that chlorhexidine in preoperative antisepsis is more efficient than other antiseptics in reducing SSI rates.

PROCEDURES

We conducted a systematic review from 2000-2014 in all languages. The primary end point was SSI incidence and secondary skin bacterial colonization.

RESULTS

Nineteen studies were included. Meta-analysis were conducted for comparable studies for both outcomes. The results of the meta-analysis, including all of the studies in which chlorhexidine was compared with iodophor, were in favor of chlorhexidine for both SSI incidence (risk ratio [RR], 0.70; 95% confidence interval [CI], 0.52-0.92) and bacterial skin colonization (RR, 0.45; 95% CI, 0.36-0.55).

CONCLUSIONS

There is moderate-quality evidence supporting the use of chlorhexidine for preoperative skin antisepsis and high-quality evidence that the use of chlorhexidine is associated with fewer positive skin cultures. Further rigorous trials will be welcomed to attain stronger evidence as to the best antiseptic to be used before surgery.

Hospital-Acquired Infections: Current Trends and Prevention

Health care-associated infections (HAIs) are the primary cause of preventable death and disability among hospitalized patients. According to the Centers for Disease Control and Prevention (CDC), complications or infections secondary to either device implantation or surgery are referred to as HAIs. Specifically, the CDC monitors surgical site infections, central-line-associated bloodstream infection, catheter-associated urinary tract infections, and ventilator-associated pneumonias. This article explores HAIs specific to pathophysiology, epidemiology, and prevention, and how nurses can work together with other health care providers to decrease the incidence of these preventable complications.

National surveillance of health care-associated infections in Egypt: Developing a sustainable program in a resource-limited country

BACKGROUND

Health care-associated infections (HAIs) are a major global public health concern. The lack of surveillance systems in developing countries leads to an underestimation of the global burden of HAI. We describe the process of developing a national HAI surveillance program and the magnitude of HAI rates in Egypt.

METHODS

The detailed process of implementation of a national HAI surveillance program is described. A 3-phase surveillance approach was implemented in intensive care units (ICUs). This article focuses on results from the phase 2 surveillance. Standard surveillance definitions were used, clinical samples were processed by the hospital laboratories, and results were confirmed by a reference laboratory.

RESULTS

Ninety-one ICUs in 28 hospitals contributed to 474,544 patient days and 2,688 HAIs. Of these, 30% were bloodstream infections, 29% were surgical site infections, 26% were pneumonia, and 15% were urinary tract infections. Ventilator-associated pneumonia had the highest incidence of device-associated infections (4.3/1,000 ventilator days). The most common pathogens reported were Klebsiella spp (28.7%) and Acinetobacter spp (13.7%). Of the Acinetobacter spp, 92.8% (157/169) were multidrug resistant, whereas 42.5% (151/355) of the Klebsiella spp and 54% (47/87) of Escherichia coli were extended-spectrum β-lactamase producers.

CONCLUSIONS

Implementation of a sustainable surveillance system in a resource-limited country was possible following a stepwise approach with continuous evaluation. Enhancing infection prevention and control programs should be an infection control priority in Egypt.

Encouraging employees to speak up to prevent infections: Opportunities to leverage quality improvement and care management processes

BACKGROUND

Central line-associated bloodstream infections (CLABSIs) are associated with increased morbidity, mortality, and cost for U.S. hospitals, but many infections are preventable. Employees' willingness to speak up about errors or opportunities for improvement has been associated with a stronger safety culture in hospitals. However, the link between organizations' efforts to promote speaking up and prevent CLABSIs has not been studied.

METHODS

This exploratory, qualitative study included interviews with 158 key informants, including hospital executives, managers, and staff employees, in 6 hospitals that participated in the federally funded On the CUSP-Stop BSI initiative. Verbatim transcripts were analyzed to examine whether and how speaking up was addressed in CLABSI prevention efforts.

RESULTS

Hospitals implementing evidence-based practices for CLABSI prevention facilitated employees' improvement-oriented speaking up by leveraging quality improvement and care management processes. Leader behavior, employee training, and error reporting systems also facilitated speaking up. Although the focus of this study was on CLABSI prevention, broader organizational practices to improve patient safety were salient in creating a nonpunitive, highly inclusive environment in which employees felt comfortable speaking up.

CONCLUSIONS

These findings provide insight into the factors that may support speaking up to foster a safety culture and prevent health care-associated infection at unit and organization levels.

Prevention and control of health care-associated infections in Iran: A qualitative study to explore challenges and barriers

BACKGROUND

Globally, the health and economic burden posed by health care-associated infections (HAIs) remains wide and severe. To curb the burden associated with HAIs, countries, including Iran, aim at HAI prevention and control. This study explores the challenges faced by the Iranian health system in addressing the issues associated with the prevention and control of HAIs.

METHODS

A qualitative research method was adopted in exploring the phenomenon. We used the purposive sampling approach in reaching 24 key informants at the national and subnational levels. The thematic framework analysis was conducted for analyzing the interviews.

RESULTS

Five main themes emerged from our study demonstrating the obstacles toward the prevention and control of HAIs. They include governance and stewardship, resources, safety culture, monitoring and surveillance systems, and inappropriate prescription of antibiotics.

CONCLUSIONS

Strengthening of reporting and surveillance systems for HAIs coupled with proper governance and stewardship are crucial in order to improve the health and safety of patients. However, the availability of resources, through an intersectoral approach, is essential to achieve sustained output.

Vancomycin-Resistant Enterococci: Epidemiology, Infection Prevention, and Control

Vancomycin-resistant enterococci (VRE) infections have acquired prominence as a leading cause of health care-associated infections. Understanding VRE epidemiology, transmission modes in health care settings, risk factors for colonization, and infection is essential to prevention and control of VRE infections. Infection control strategies are pivotal in management of VRE infections and should be based on patient characteristics, hospital needs, and available resources. Hand hygiene is basic to decrease acquisition of VRE. The effectiveness of surveillance and contact precautions is variable and controversial in endemic settings, but important during VRE outbreak investigations and control. Environmental cleaning, chlorhexidine bathing, and antimicrobial stewardship are vital in VRE prevention and control.

Trends in mortality, length of stay, and hospital charges associated with health care-associated infections, 2006-2012

BACKGROUND

Many factors associated with hospital-acquired infections (HAIs), including reimbursement policies, drug prices, practice patterns, and the distribution of organisms causing infections, change over time. We examined whether outcomes, including mortality, length of stay (LOS), daily charges, and total charges associated with HAIs, changed during 2006-2012.

METHODS

Electronic data on adults discharged from 2 tertiary-quaternary hospitals and 1 community hospital during 2006-2012 were collected retrospectively. Computerized algorithms identified infections using laboratory and administrative codes. Propensity scores were used to match cases with uninfected controls. Differences in mortality, LOS, daily charges, and total charges were modeled against infection status and time period (2006-2008 vs 2009-2012), including interaction for infection status by time period.

RESULTS

Among 352,077 discharges, 24,466 HAIs were detected. There was no significant change in mortality. LOS declined only for bloodstream infections (3-day reduction; P < 0.01). Daily charges rose 4% for urinary tract infections but did not change significantly for other HAIs. Total charges declined by 11% for bloodstream infections and 13% for pneumonia.

CONCLUSIONS

We found no appreciable or consistent improvement in HAI mortality or LOS during 2006-2012. Costs of bloodstream infections and pneumonia have declined, with most of the change occurring before 2008.

Effectiveness of ultraviolet devices and hydrogen peroxide systems for terminal room decontamination: Focus on clinical trials

Over the last decade, substantial scientific evidence has accumulated that indicates contamination of environmental surfaces in hospital rooms plays an important role in the transmission of key health care-associated pathogens (eg, methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, Clostridium difficile, Acinetobacter spp). For example, a patient admitted to a room previously occupied by a patient colonized or infected with one of these pathogens has a higher risk for acquiring one of these pathogens than a patient admitted to a room whose previous occupant was not colonized or infected. This risk is not surprising because multiple studies have demonstrated that surfaces in hospital rooms are poorly cleaned during terminal cleaning. To reduce surface contamination after terminal cleaning, no touch methods of room disinfection have been developed. This article will review the no touch methods, ultraviolet light devices, and hydrogen peroxide systems, with a focus on clinical trials which have used patient colonization or infection as an outcome. Multiple studies have demonstrated that ultraviolet light devices and hydrogen peroxide systems have been shown to inactivate microbes experimentally plated on carrier materials and placed in hospital rooms and to decontaminate surfaces in hospital rooms naturally contaminated with multidrug-resistant pathogens. A growing number of clinical studies have demonstrated that ultraviolet devices and hydrogen peroxide systems when used for terminal disinfection can reduce colonization or health care-associated infections in patients admitted to these hospital rooms.

Marked reduction in compliance with central line insertion practices (CLIP) when accounting for missing CLIP data and incomplete line capture

Adherence to central line insertion practices can significantly reduce infections and is used as a hospital benchmark for quality. However, current national standards for central line insertion practices (CLIP) compliance calculation do not include missing CLIP forms. We found adherence rates significantly decreased when accounting for all lines at an academic medical center.

Health care-associated infections surveillance in an intensive care unit of a university hospital in China, 2010-2014: Findings of International Nosocomial Infection Control Consortium

Using a standardized methodology by the National Nosocomial Infection Surveillance System, a continuous health care-associated infections (HAIs) surveillance was conducted in our mixed intensive care unit at a Chinese teaching hospital. During the study period (2010-2014), 4,013 patients were hospitalized for 32,924 bed days and acquired 427 HAIs (482 HAI events), with an overall rate of 10.64% and 14.640 HAIs per 1,000 bed days. Ventilator-associated pneumonia was the most common device-associated health care-acquired infection, with an incidence rate of 19.561 per 1,000 mechanical ventilator days.

Good medical practices in the use of antibiotic prophylaxis in a surgery ward: Results of a 2013 Apulian study

This study describes the changes in the performance of health care workers regarding the control of health care-associated infection in a surgical ward of University Hospital Policlinico, Bari, Italy, before and after a training program and adoption of bundles on antibiotic therapy. There were 194 patients recruited (pre: n = 98; post: n = 96), of which 149 (76.8%) had undergone surgery. We documented a change in the proportions of patients who received in-ward prophylactic antibiotics (from 46/98 to 22/96, P < .05), surgical patients undergoing antibiotic prophylaxis in the operating room (from 18/64 to 36/85, P < .05), and average duration of prophylaxis (from 5.9 ± 4.9 to 2.9 ± 2.7 days, P < .0001). Results confirmed correspondence between the intervention and results recorded.
