A previously uncommon strain of C. difficile with variations in toxin genes has become more resistant to fluoroquinolones and has emerged as a cause of geographically dispersed outbreaks of C. difficile-associated disease.

Background Unnecessary antibiotic use (AU) contributes to increased rates of Clostridioides difficile infection (CDI). The impact of antibiotic restriction on hospital-onset CDI (HO-CDI) has not been assessed in a large group of US acute care hospitals (ACHs). Methods We examined cross-sectional and temporal associations between rates of hospital-level AU and HO-CDI using data from 549 ACHs. HO-CDI was defined as a discharge with a secondary International Classification of Diseases, Ninth Revision, Clinical Modification code for CDI (008.45), and treatment with metronidazole or oral vancomycin > 3 days after admission. Analyses were performed using multivariable generalized estimating equation models adjusting for patient and hospital characteristics. Results During 2006–2012, the unadjusted annual rates of HO-CDI and total AU were 7.3 per 10 000 patient-days (PD) (95% confidence interval [CI], 7.1–7.5) and 811 days of therapy (DOT)/1000 PD (95% CI, 803–820), respectively. In the cross-sectional analysis, for every 50 DOT/1000 PD increase in total AU, there was a 4.4% increase in HO-CDI. For every 10 DOT/1000 PD increase in use of third- and fourth-generation cephalosporins or carbapenems, there was a 2.1% and 2.9% increase in HO-CDI, respectively. In the time-series analysis, the 6 ACHs with a ≥30% decrease in total AU had a 33% decrease in HO-CDI (rate ratio, 0.67 [95% CI, .47–.96]); ACHs with a ≥20% decrease in fluoroquinolone or third- and fourth-generation cephalosporin use had a corresponding decrease in HO-CDI of 8% and 13%, respectively. Conclusions At an ecologic level, reductions in total AU, use of fluoroquinolones, and use of third- and fourth-generation cephalosporins were each associated with decreased HO-CDI rates.

Context: Access to high quality primary care was identified by Healthy People 2010 as one of the mechanisms through which racial and ethnic disparities in health might be reduced. Despite the well-established connections between good primary care and health, the scientific evidence on whether good primary care can reduce racial disparities in health is sparse.Objective: To examine whether better primary care experience can attenuate racial and ethnic disparities in self-reported health status.Data Sources: The 1996 to 1997 and 1998 to 1999 data from the Community Tracking Study (CTS) sponsored by the Robert Wood Johnson Foundation.Study Design: Cross-sectional, bivariate, and multivariate analyses of inter-relationships between self-rated general and mental health status, access to and interpersonal relationship with primary care provider, and vulnerability measured by race and poverty status.Results: We found that higher quality primary care levels are associated with reduced racial and ethnic disparities in health status, as measured by self-rated general and mental health. This relationship is particularly pronounced for the racial and ethnic minorities living at or below poverty level. Based on the data from 1996 to 1999, the study also confirmed the presence of significant and persistent health differences across racial and ethnic groups.

Previously reported associations between hospital-level antibiotic use and hospital-onset Clostridioides difficile infection (HO-CDI) were reexamined using 2012–2018 data from a new cohort of US acute-care hospitals. This analysis revealed significant positive associations between total, third-generation, and fourth-generation cephalosporin, fluoroquinolone, carbapenem, and piperacillin-tazobactam use and HO-CDI rates, confirming previous findings.

The disruptions of the coronavirus disease 2019 (COVID‐19) pandemic impacted the delivery and utilization of healthcare services with potential long‐term implications for population health and the hospital workforce. Using electronic health record data from over 700 US acute care hospitals, we documented changes in admissions to hospital service areas (inpatient, observation, emergency room [ER], and same‐day surgery) during 2019−2020 and examined whether surges of COVID‐19 hospitalizations corresponded with increased inpatient disease severity and death rate. We found that in 2020, hospitalizations declined by 50% in April, with greatest declines occurring in same‐day surgery (−73%). The youngest patients (0−17) experienced largest declines in ER, observation, and same‐day surgery admissions; inpatient admissions declined the most among the oldest patients (65+). Infectious disease admissions increased by 52%. The monthly measures of inpatient case mix index, length of stay, and non‐COVID death rate were higher in all months in 2020 compared with respective months in 2019.
