The impact of a comprehensive coronavirus disease 2019 (COVID-19) infection prevention bundle on non-COVID-19 hospital-acquired respiratory viral infection (HA-RVI) rates.

After implementing a coronavirus disease 2019 (COVID-19) infection prevention bundle, the incidence rate ratio (IRR) of non-severe acute respiratory coronavirus virus 2 (non-SARS-CoV-2) hospital-acquired respiratory viral infection (HA-RVI) was significantly lower than the IRR from the pre-COVID-19 period (IRR, 0.322; 95% CI, 0.266-0.393; P < .01). However, HA-RVIs incidence rates mirrored community RVI trends, suggesting that hospital interventions alone did not significantly affect HA-RVI incidence.

Creation and impact of containment units with high-risk zones during the coronavirus disease 2019 (COVID-19) pandemic.

BACKGROUND: The rapid spread of coronavirus disease 2019 (COVID-19) required swift preparation to protect healthcare personnel (HCP) and patients, especially considering shortages of personal protective equipment (PPE). Due to the lack of a pre-existing biocontainment unit, we needed to develop a novel approach to placing patients in isolation cohorts while working with the pre-existing physical space. OBJECTIVES: To prevent disease transmission to non-COVID-19 patients and HCP caring for COVID-19 patients, to optimize PPE usage, and to provide a comfortable and safe working environment. METHODS: An interdisciplinary workgroup developed a combination of approaches to convert existing spaces into COVID-19 containment units with high-risk zones (HRZs). We developed standard workflow and visual management in conjunction with updated staff training and workflows. The infection prevention team created PPE standard practices for ease of use, conservation, and staff safety. RESULTS: The interventions resulted in 1 possible case of patient-to-HCP transmission and zero cases of patient-to-patient transmission. PPE usage decreased with the HRZ model while maintaining a safe environment of care. Staff on the COVID-19 units were extremely satisfied with PPE availability (76.7%) and efforts to protect them from COVID-19 (72.7%). Moreover, 54.8% of HCP working in the COVID-19 unit agreed that PPE monitors played an essential role in staff safety. CONCLUSIONS: The HRZ model of containment unit is an effective method to prevent the spread of COVID-19 with several benefits. It is easily implemented and scaled to accommodate census changes. Our experience suggests that other institutions do not need to modify existing physical structures to create similarly protective spaces.

Standing-up COVID-19 monoclonal antibody infusion centers: Infection prevention and control.

This paper describes the creation of outpatient monoclonal antibody (mAb) infusion centers for COVID-19 patients in a large academic medical center. It shows how the early and consistent partnership between infection prevention and the clinical and operational teams to establish and implement policies and procedures led to efficient and safe workflows.

Assessing compliance of infection prevention mitigation strategies in hospital construction and renovation.

Hospital-associated fungal infections from construction and renovation activities can be mitigated using an infection control risk assessment (ICRA) and implementation of infection prevention measures. The effectiveness of these measures depends on proper installation and maintenance. Consistent infection prevention construction rounding with feedback is key to ongoing compliance.

The Disproportionate Impact of COVID-19 Pandemic on Healthcare-Associated Infections in Community Hospitals: Need for Expanding the Infectious Disease Workforce.

BACKGROUND: The COVID-19 pandemic had a considerable impact on US healthcare systems, straining hospital resources, staff, and operations. However, a comprehensive assessment of the impact on healthcare associated infections (HAIs) across different hospitals with varying level of infectious disease (ID) physician expertise, resources, and infrastructure is lacking. METHODS: This retrospective longitudinal multi-center cohort study included central-line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), C. difficile infections (CDIs), and ventilator-associated events (VAEs) from 53 hospitals (academic and community) in Southeastern United States from January 1, 2018 to March 31, 2021. Segmented negative binomial regression generalized estimating equations models estimated changes in monthly incidence rates in the baseline (01/2018 - 02/2020) compared to the pandemic period (03/2020 - 03/2021, further divided into three pandemic phases). RESULTS: CLABSIs and VAEs increased by 24% and 34% respectively during the pandemic period. VAEs increased in all phases of the pandemic, while CLABSIs increased in later phases of the pandemic. CDI trend increased by 4.2% per month in the pandemic period. On stratifying the analysis by hospital characteristics, the impact of the pandemic on healthcare-associated infections was more significant in smaller sized and community hospitals. CAUTIs did not change significantly during the pandemic across all hospital types. CONCLUSIONS: CLABSIs, VAEs, and CDIs increased significantly during the pandemic, especially in smaller community hospitals, most of which lack ID physician expertise. Future efforts should focus on better understanding challenges faced by community hospitals, strengthening infection prevention infrastructure, and expanding the ID workforce, particularly to community hospitals.

assessment of Vaccine Interest in Unvaccinated COVID-19–positive inpatients

Background: Although vaccine hesitancy has been an issue for many years, it has become a major point of contention in the effort to mitigate the COVID-19 pandemic. In August 2021, a large academic medical facility began capturing the vaccination status of admitted COVID-19–positive patients, as well as their interest in the COVID-19 vaccine. We performed a descriptive analysis on the characteristics of unvaccinated patients who contracted COVID-19 and their interest in receiving the COVID-19 vaccine. Methods: Patient history and physical (H&P) notes and demographic data were collected using the internal data warehouse sourced from the electronic medical record for all SARS-COV-2–positive inpatient admissions to UNC Medical Center and UNC Chatham from August 1, 2021, to January 11, 2022. Manual chart reviews of progress notes were completed for patients whose history was not recorded in the initial H&P. Demographic data were summarized by vaccine status overall and by interest in COVID-19 vaccine among unvaccinated patients. We performed χ2 to determine demographic differences between the interested and uninterested unvaccinated groups. Results: In total, 536 patients were admitted with COVID-19 from August 1, 2021, to January 11, 2022. Of these, 15% were fully vaccinated (2 doses mRNA plus 1 dose J&J);5.4% were partially vaccinated;75.7% were unvaccinated;and 2.9% had an unknown vaccination status. Demographic characteristics are presented in Table 1. The most common demographics were consistent among the fully vaccinated and unvaccinated groups, with the exception of sex and age group (Table 1). For those whose interest data were available (n = 164), 34% were uninterested in receiving the COVID-19 vaccine. Importantly, race and age were statistically significantly different (P < .05) between the unvaccinated interested and unvaccinated uninterested groups. Conclusions: Even after experiencing COVID-19 firsthand and being hospitalized, some people who remain uninterested in receiving the COVID-19 vaccine. This population had a statistically higher proportion of white and older individuals than the unvaccinated interested group. Recommendations from healthcare providers might not be effective in persuading this population to be vaccinated. Instead, grassroots alternatives might be more successful. Additional analysis should be considered on whether patients who expressed interest in COVID-19 vaccine received immunization.Funding: NoneDisclosures: None

Reduction and persistence of co-circulating respiratory viruses during the SARS-CoV-2 pandemic.

To evaluate the co-circulation of respiratory viruses during the SARS-CoV-2 Alpha surge, we performed a molecular respiratory panel on 1,783 nasopharyngeal swabs collected between January 15 and April 15, 2021, from symptomatic outpatients that tested negative for SARS-CoV-2 in North Carolina. Of these, 373 (20.9%) were positive for at least 1 virus tested on the panel. Among positive tests, over 90% were positive for rhinovirus and/or enterovirus, either as a single infection or coinfection, illustrating persistent co-circulation of some respiratory viruses despite active infection control measures.

Sustainability of a well-established hand hygiene program during the coronavirus disease 2019 (COVID-19) pandemic.

Overall, engagement and compliance from the crowd-sourced hand hygiene observation program, Clean-In-Clean-Out (CICO), were similar between 2019 (96.6%) and 2020 (96.7%) despite fluctuations within 2020 that reflected our hospital's coronavirus disease 2019 (COVID-19) experience. Shared responsibility and just-in-time reminders can allow manual hand hygiene observation models to be sustainable.

Strategies utilized to prevent and control SARS-CoV-2 transmission in two congregate, psychiatric healthcare settings during the pandemic.

BACKGROUND: The COVID-19 pandemic has had a substantial effect on the delivery of psychiatric health care. Inpatient psychiatric health care facilities have experienced outbreaks of COVID-19, making these areas particularly vulnerable. METHODS: Our facility used a multidisciplinary approach to implement enhanced infection prevention and control (IPC) interventions in our psychiatric health care areas. RESULTS: In a 16-month period during the COVID-19 pandemic, our 2 facilities provided >29,000 patient days of care to 1,807 patients and identified only 47 COVID-19 positive psychiatric health inpatients (47/1,807, or 2.6%). We identified the majority of these cases by testing all patients at admission, preventing subsequent outbreaks. Twenty-one psychiatric health care personnel were identified as COVID+ during the same period, with 90% linked to an exposure other than a known positive case at work. DISCUSSION: The IPC interventions we implemented provided multiple layers of safety for our patients and our staff. Ultimately, this resulted in low SARS-CoV-2 infection rates within our facilities. CONCLUSIONS: Psychiatric health care facilities are uniquely vulnerable to COVID-19 outbreaks because they are congregate units that promote therapeutic interactions in shared spaces. IPC interventions used in acute medical care settings can also work effectively in psychiatric health care, but often require modifications to ensure staff and patient safety.

Building a personal protective equipment monitor team as part of a comprehensive COVID-19 prevention strategy.

We instituted Personal Protective Equipment (PPE) Monitors as part of our care of COVID-19 patients in high-risk zones. PPE Monitors aided health care personnel (HCP) in donning and doffing, which contributed to nearly zero transmission of COVID-19 to HCP, despite their care of over 1400 COVID-19 patients.

COVID-19 Surveillance: Not Everything That Counts Can be Counted, and not Everything That Can be Counted Countsa.

Infectious disease surveillance is one of the most valuable tools in monitoring the COVID-19 pandemic. Here we examine the components of an ideal surveillance system and assess the effectiveness of COVID-19 surveillance in North Carolina and around the world.
