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.

Regional outbreak of multidrug-resistant Klebsiella pneumoniae carbapenemase-producing Pseudomonas Aeruginosa.

Klebsiella pneumoniae carbapenemase-producing P. aeruginosa (KPC-CRPA) are rare in the United States. An outbreak of KPC-CRPA was investigated in Texas using molecular and epidemiologic methods and 17 cases of KPC-CRPA were identified. The isolates were genetically related and harbored the emerging P. aeruginosa multilocus sequence type 235, the first in the United States.

Epidemic Clostridioides difficile Ribotype 027 Lineages: Comparisons of Texas Versus Worldwide Strains.

BACKGROUND: The epidemic Clostridioides difficile ribotype 027 strain resulted from the dissemination of 2 separate fluoroquinolone-resistant lineages: FQR1 and FQR2. Both lineages were reported to originate in North America; however, confirmatory large-scale investigations of C difficile ribotype 027 epidemiology using whole genome sequencing has not been undertaken in the United States. METHODS: Whole genome sequencing and single-nucleotide polymorphism (SNP) analysis was performed on 76 clinical ribotype 027 isolates obtained from hospitalized patients in Texas with C difficile infection and compared with 32 previously sequenced worldwide strains. Maximum-likelihood phylogeny based on a set of core genome SNPs was used to construct phylogenetic trees investigating strain macro- and microevolution. Bayesian phylogenetic and phylogeographic analyses were used to incorporate temporal and geographic variables with the SNP strain analysis. RESULTS: Whole genome sequence analysis identified 2841 SNPs including 900 nonsynonymous mutations, 1404 synonymous substitutions, and 537 intergenic changes. Phylogenetic analysis separated the strains into 2 prominent groups, which grossly differed by 28 SNPs: the FQR1 and FQR2 lineages. Five isolates were identified as pre-epidemic strains. Phylogeny demonstrated unique clustering and resistance genes in Texas strains indicating that spatiotemporal bias has defined the microevolution of ribotype 027 genetics. CONCLUSIONS: Clostridioides difficile ribotype 027 lineages emerged earlier than previously reported, coinciding with increased use of fluoroquinolones. Both FQR1 and FQR2 ribotype 027 epidemic lineages are present in Texas, but they have evolved geographically to represent region-specific public health threats.

The role of colleges and schools of pharmacy in the advent of Healthy People 2020.

As the need for more experiential sites increases, colleges and schools of pharmacy should consider innovative and strategic approaches to expansion including adding programs that would address the target areas emphasized by Healthy People 2020. Healthy People 2020 encompasses the following areas: adolescent health, early and middle childhood, genomics, global health, health information technology, healthcare-associated infections, hearing and other sensory or communicating disorders (ear, nose, throat-voice, speech and language), weight status, older adults, quality of life and well-being, and social determinants of health. Academic leaders should consider what role exists for pharmacy practice in these areas and focus future program and curriculum development on Healthy People 2020 topic areas.
