COVID-19 in Long-Term Care: The Built Environment Impact on Infection Control

PURPOSE

The purpose of this article is to review available literature for evidence-based impact of the built environment upon the prevention and management of COVID-19 with a view to emphasizing lessons learned for future infection control of pandemics.

BACKGROUND

This is urgently needed given the devastation brought upon long-term care residents worldwide. Long-term care (LTC) facilities face a battle to protect their residents. Previous studies of infection control design issues have focused generally on Fomites: that is, contaminated objects and surfaces. As COVID-19 has been shown to be largely spread through the air, this article will broaden the focus to include engineering controls that effect this type of transmission.

METHOD

A literature search was conducted using key words such as long-term care facilities, built environment, COVID-19, infection control, and nursing homes.

RESULTS

Results were sorted using an engineering controls pyramid developed by the author to stratify approaches to LTC infrastructure. Basically, six elements were supported: ventilation, spatial separation, physical barriers, hand hygiene stations, resident room zones, and private rooms.

IMPLICATIONS

Conclusions were that the built environment has a major impact on infection control that can be deleterious or beneficial. Substantial changes need to be made to protect the very vulnerable LTC population from future pandemics and infectious diseases.

Protecting Nursing Homes and Long-Term Care Facilities From COVID-19: A Rapid Review of International Evidence

OBJECTIVES

The COVID-19 pandemic has highlighted the extreme vulnerability of older people and other individuals who reside in long-term care, creating an urgent need for evidence-based policy that can adequately protect these community members. This study aimed to provide synthesized evidence to support policy decision making.

DESIGN

Rapid narrative review investigating strategies that have prevented or mitigated SARS-CoV-2 transmission in long-term care.

SETTING AND PARTICIPANTS

Residents and staff in care settings such as nursing homes and long-term care facilities.

METHODS

PubMed/Medline, Cochrane Library, and Scopus were systematically searched, with studies describing potentially effective strategies included. Studies were excluded if they did not report empirical evidence (eg, commentaries and consensus guidelines). Study quality was appraised on the basis of study design; data were extracted from published reports and synthesized narratively using tabulated data extracts and summary tables.

RESULTS

Searches yielded 713 articles; 80 papers describing 77 studies were included. Most studies were observational, with no randomized controlled trials identified. Intervention studies provided strong support for widespread surveillance, early identification and response, and rigorous infection prevention and control measures. Symptom- or temperature-based screening and single point-prevalence testing were found to be ineffective, and serial universal testing of residents and staff was considered crucial. Attention to ventilation and environmental management, digital health applications, and acute sector support were also considered beneficial although evidence for effectiveness was lacking. In observational studies, staff represented substantial transmission risk and workforce management strategies were important components of pandemic response. Higher-performing facilities with less crowding and higher nurse staffing ratios had reduced transmission rates. Outbreak investigations suggested that facility-level leadership, intersectoral collaboration, and policy that facilitated access to critical resources were all significant enablers of success.

CONCLUSIONS AND IMPLICATIONS

High-quality evidence of effectiveness in protecting LTCFs from COVID-19 was limited at the time of this study, though it continues to emerge. Despite widespread COVID-19 vaccination programs in many countries, continuing prevention and mitigation measures may be required to protect vulnerable long-term care residents from COVID-19 and other infectious diseases. This rapid review summarizes current evidence regarding strategies that may be effective.

The impact of COVID-19 in an assisted living community

The purpose of this study was to use routinely collected resident assessment data from a single site to evaluate the impact of COVID-19 restrictions on cognition, physical function and behavioral symptoms of residents with dementia. Specifically, it was hypothesized that controlling for age and sex, there would be a decline in cognition and function and an increase in behavioral symptoms at 12 months post implementation of COVID-19 restrictions. Twelve residents from a single memory care site with required Resident Assessments completed prior to and 12 month post initiation of the pandemic and associated quarantines were included. No significant change was noted in function or behavioral symptoms but there was a statistically significant decline in cognition over the 12 month period. Although this study did not support our hypothesis, the findings supported some prior research also noting little significant change among the majority of individuals over the course of the pandemic regardless of regulations.

Modeling COVID-19 spread in small colleges

We develop an agent-based model on a network meant to capture features unique to COVID-19 spread through a small residential college. We find that a safe reopening requires strong policy from administrators combined with cautious behavior from students. Strong policy includes weekly screening tests with quick turnaround and halving the campus population. Cautious behavior from students means wearing facemasks, socializing less, and showing up for COVID-19 testing. We also find that comprehensive testing and facemasks are the most effective single interventions, building closures can lead to infection spikes in other areas depending on student behavior, and faster return of test results significantly reduces total infections.

Optimizing Medication Management During the COVID-19 Pandemic: It Takes a Village

Coronavirus disease 2019 (COVID-19) is an unprecedented pandemic that has particularly affected nursing homes and long-term care facilities. To support frontline health care professionals caring for older adults, the current article provides guidance on strategies to optimize medication management within nursing homes and long-term care facilities. In addition, the article reviews two medications that have been granted U.S. Food and Drug Administration emergency use authorization for treatment of COVID-19: hydroxychloroquine and remdesivir. Finally, this article highlights resources and strategies for improving communication among an interprofessional team during the ongoing pandemic, as well as education on COVID-19. Although the COVID-19 pandemic has had many negative implications, it has also brought to attention opportunities to improve the delivery of care and increase the importance of working as an interprofessional team ("village") during these challenging times.
