Contact precautions as a barrier to hand hygiene: The Plan-Do-Study-Act (PDSA) framework to improve compliance with gloved hand hygiene.

In an identified quality improvement effort, nurses were observed regarding their workflow while in contact precaution rooms. Multiple opportunities for hand hygiene were missed while nurses were in gloves, predominantly while moving between "dirty" and "clean" tasks. An education initiative afterward did not show improvement in hand hygiene rates.

Are contact precautions "essential" for the prevention of healthcare-associated methicillin-resistant Staphylococcus aureus?

The recently updated SHEA/IDSA/APIC practice recommendations for MRSA prevention in acute care facilities list contact precautions (CP) for patients known to be infected or colonized with MRSA as an "essential practice", meaning that it should be adopted in all acute care facilities. We argue that existing evidence on benefits and harms associated with CP do not justify this recommendation. There are no controlled trials that support broad use of CP for MRSA prevention. Data from hospitals that have discontinued CP for MRSA have found no impact on MRSA acquisition or infection. The burden and harms of CP remain concerning, including the environmental impact of increased gown and glove use. We suggest that CP be included among other "additional approaches" to MRSA prevention that can be implemented under specific circumstances (e.g. outbreaks, evidence of ongoing transmission despite application of essential practices).

Hospital return-to-work practices for healthcare providers infected with severe acute respiratory coronavirus virus 2 (SARS-CoV-2).

A survey of academic medical-center hospital epidemiologists indicated substantial deviation from Centers for Disease Control and Prevention guidance regarding healthcare providers (HCPs) recovering from coronavirus disease 2019 (COVID-19) returning to work. Many hospitals continue to operate under contingency status and have HCPs return to work earlier than recommended.

Rising from the pandemic ashes: Reflections on burnout and resiliency from the infection prevention and antimicrobial stewardship workforce.

Hospital epidemiologists, infection preventionists, and antimicrobial stewards are integral to the pandemic workforce. However, regardless of pandemic surge or postsurge conditions, their workload remains high due to constant vigilance for new variants, emerging data, and evolving public health guidance. We describe the factors that have led to burnout and suggest strategies to enhance resilience.

Staphylococcal decolonization to prevent surgical site infection: Is there a role in colorectal surgery?

Objective: We implemented a preoperative staphylococcal decolonization protocol for colorectal surgeries if efforts to further reduce surgical site infections (SSIs). Design: Retrospective observational study. Setting: Tertiary-care, academic medical center. Patients: Adult patients who underwent colorectal surgery, as defined by National Healthcare Safety Network (NHSN), between July 2015 and June 2020. Emergent cases were excluded. Methods: Simple and multivariable logistic regression were performed to evaluate the relationship between decolonization and subsequent SSI. Other predictive variables included age, sex, body mass index, procedure duration, American Society of Anesthesiology (ASA) score, diabetes, smoking, and surgical oncology service. Results: In total, 1,683 patients underwent nonemergent NHSN-defined colorectal surgery, and 33.7% underwent the staphylococcal decolonization protocol. SSI occurred in 92 (5.5%); 53 were organ-space infections and 39 were superficial wound infections. We detected no difference in overall SSIs between those decolonized and not decolonized (P = .17). However, superficial wound infections were reduced in the group that received decolonization versus those that did not: 7 (1.2%) of 568 versus 32 (2.9%) of 1,115 (P = .04). Conclusions: Staphylococcal decolonization may prevent a subset of SSIs in patients undergoing colorectal surgery.

At the vanguard: Leaders' perspectives on establishing healthcare system infection prevention programs.

Hospitals are increasingly consolidating into health systems. Some systems have appointed healthcare epidemiologists to lead system-level infection prevention programs. Ideal program infrastructure and support resources have not been described. We informally surveyed 7 healthcare epidemiologists with recent experience building and leading system-level infection prevention programs. Key facilitators and barriers for program structure and implementation are described.

Impact of cascade reporting of antimicrobial susceptibility on fluoroquinolone and meropenem consumption at a Veterans' Affairs medical center.

OBJECTIVE: To determine whether cascade reporting is associated with a change in meropenem and fluoroquinolone consumption. DESIGN: A quasi-experimental study was conducted using an interrupted time series to compare antimicrobial consumption before and after the implementation of cascade reporting. SETTING: A 399-bed, tertiary-care, Veterans' Affairs medical center. PARTICIPANTS: Antimicrobial consumption data across 8 inpatient units were extracted from the Center for Disease Control and Prevention (CDC) National Health Safety Network (NHSN) antimicrobial use (AU) module from April 2017 through March 2019, reported as antimicrobial days of therapy (DOT) per 1,000 days present (DP). INTERVENTION: Cascade reporting is a strategy of reporting antimicrobial susceptibility test results in which secondary agents are only reported if an organism is resistant to primary, narrow-spectrum agents. A multidisciplinary team developed cascade reporting algorithms for gram-negative bacteria based on local antibiogram and infectious diseases practice guidelines, aimed at restricting the use of fluoroquinolones and carbapenems. The algorithms were implemented in March 2018. RESULTS: Following the implementation of cascade reporting, mean monthly meropenem (P =.005) and piperacillin/tazobactam (P = .002) consumption decreased and cefepime consumption increased (P < .001). Ciprofloxacin consumption decreased by 2.16 DOT per 1,000 DP per month (SE, 0.25; P < .001). Clostridioides difficile rates did not significantly change. CONCLUSION: Ciprofloxacin consumption significantly decreased after the implementation of cascade reporting. Mean meropenem consumption decreased after cascade reporting was implemented, but we observed no significant change in the slope of consumption. cascade reporting may be a useful strategy to optimize antimicrobial prescribing.

Evaluation of optimal treatment for urinary tract infections in outpatient clinics at an academic medical center: Opportunities for antimicrobial stewardship.

Outpatient empiric urinary tract infection (UTI) prescribing is an area of interest for antimicrobial stewardship efforts. We conducted a retrospective chart review evaluating optimal antibiotic prescribing for UTIs in our internal medicine and urology clinics and found significant differences in prescribing patterns between provider type and UTI category. These data will inform our antimicrobial stewardship efforts in these clinics.

Changes in nursing team composition and risk of device-associated infection in intensive care units.

The relationship between nursing staffing levels and healthcare-associated infections (HAIs) has been explored previously with conflicting results. This study uses daily shift records from 2 intensive care units (ICUs) to evaluate whether nuanced changes in nursing team composition impacts subsequent risk for device associated HAIs. Staffing deficiencies may be associated with periods of risk prior to central line-associated bloodstream infection in the ICU.

Optimizing the Management of Uncomplicated Gram-Negative Bloodstream Infections: Consensus Guidance Using a Modified Delphi Process.

BACKGROUND: Guidance on the recommended durations of antibiotic therapy, the use of oral antibiotic therapy, and the need for repeat blood cultures remain incomplete for gram-negative bloodstream infections. We convened a panel of infectious diseases specialists to develop a consensus definition of uncomplicated gram-negative bloodstream infections to assist clinicians with management decisions. METHODS: Panelists, who were all blinded to the identity of other members of the panel, used a modified Delphi technique to develop a list of statements describing preferred management approaches for uncomplicated gram-negative bloodstream infections. Panelists provided level of agreement and feedback on consensus statements generated and refined them from the first round of open-ended questions through 3 subsequent rounds. RESULTS: Thirteen infectious diseases specialists (7 physicians and 6 pharmacists) from across the United States participated in the consensus process. A definition of uncomplicated gram-negative bloodstream infection was developed. Considerations cited by panelists in determining if a bloodstream infection was uncomplicated included host immune status, response to therapy, organism identified, source of the bacteremia, and source control measures. For patients meeting this definition, panelists largely agreed that a duration of therapy of ~7 days, transitioning to oral antibiotic therapy, and forgoing repeat blood cultures, was reasonable. CONCLUSIONS: In the absence of professional guidelines for the management of uncomplicated gram-negative bloodstream infections, the consensus statements developed by a panel of infectious diseases specialists can provide guidance to practitioners for a common clinical scenario.

COVID-19 and antimicrobial stewardship: lessons learned, best practices, and future implications.

The coronavirus disease 2019 (COVID-19) pandemic has had a profound and often devastating impact on global healthcare systems. Healthcare systems have had to repurpose programs and staff as part of COVID-19 relief efforts. The infrastructure and skilled personnel of antimicrobial stewardship programs (ASPs) have been utilized in new ways as part of COVID-19 pandemic response efforts. A critical focus of ASPs both before and during the pandemic has been on limiting the development of antimicrobial resistance. Fortunately, existing data indicate that rates of bacterial co-infection are relatively low and ASPs should continue aggressive efforts to limit unnecessary antimicrobial use. ASPs have taken a lead role in COVID-19 focused guideline creation and curation, as well as in helping to steward access to potential novel therapeutic agents. Disparities in ASP program resources and personnel exist, and ASP activities focused on the COVID-19 response should be tailored to individual settings. There is an urgent need for research to help inform ASP best practices within pandemic response efforts that take into account local resources. Investment in infrastructure and personnel is urgently needed both in the context of current relief efforts and to prepare for future pandemics.
