Preparedness and response of assisted living facilities toward COVID-19 infection control in Houston, Texas, USA.

Background: Long-term care facilities (LTCFs) including assisted living facilities (ALFs) are hubs for high transmission and poor prognosis of COVID-19 among the residents who are more susceptible due to old age and comorbidities.

Aim: Houston Health Department conducted assessments of ALFs within the City of Houston to determine preparedness and existing preventive measures at the facilities.

Methods: Onsite assessments were conducted at ALFs using a modified CDC Infection Control Assessment and Response (ICAR) Tool. Data was obtained on IPC measures, training, testing, vaccination etc. Data was analyzed, frequencies generated, and bivariate associations determined.

Results: A total of 118 facilities were assessed and categorized into small scale 46 (39%), medium scale 47 (40%), and large scale 25 (21%). The facilities had 2431 residents and 2290 staff. Thirty-one (26%) facilities reported an outbreak in 2020, while 14 (12%) had an ongoing outbreak. Twenty-three (97%) large-scale and 12 (26%) small-scale facilities had COVID-19 testing program. Vaccination coverage among residents ranged from 99% in large-scale to 40% in small-scale facilities but was smaller among staff at 748 (45%) in large scale, 71 (36%) in small scale, and 193 (45%) in medium scale. While 24 (96%) large-scale and 34 (77%) of small-scale facilities conducted staff training staff on IPC practices, 22 (92%) of large-scale and 19 (56%) of small-scale facility staff demonstrated capacity (p = 0.01), respectively. Visitor screening was done at 100% of large-scale and 80% of small-scale and the medium-scale ALFs.

Discussion: Assisted living facilities within the city of Houston are at various levels of preparedness and interventions with respect to COVID-19 response.
