ABSTRACT
INTRODUCTION:
Clostridioides difficile infection (CDI) is a leading cause of healthcare-associated (HA) diarrhoea. We retrospectively investigated data from a comprehensive, multidisciplinary C. difficile surveillance programme focusing on hospitalized patients in a tertiary Irish hospital over 10 years.METHODS:
Data from 2012 to 2021 were extracted from a centralized database, including patient demographics, admission, case and outbreak details, ribotypes (RTs), and (since 2016) antimicrobial exposures and CDI treatments. Counts of CDI by origin of infection were explored using ê2 analyses, Poisson regression was used to investigate trends in rates of CDI and possible risk factors. Time to recurrent CDI was examined by a Cox proportional hazards regression.RESULTS:
Over 10 years, 954 CDI patients had a 9% recurrent CDI rate. CDI testing requests occurred in only 22% of patients. Most CDIs were HA (82.2%) and affected females (odds ratio 2.3, P<0.01). Fidaxomicin significantly reduced the hazard ratio of time to recurrent CDI. No trends in HA-CDI incidence were observed despite key time-point events and increasing hospital activity. In 2021, community-associated (CA)-CDI increased. RTs did not differ for HA versus CA for the most common RTs (014, 078, 005 and 015). Average length-of-stay differed significantly between HA (67.1 days) and CA (14.6 days) CDI.CONCLUSION:
HA-CDI rates remained unchanged despite key events and increased hospital activity, whereas by 2021, CA-CDI was at its highest in a decade. The convergence of CA and HA RTs, and the proportion of CA-CDI, question the relevance of current case definitions when increasingly patients receive hospital care without an overnight hospital stay.Palabras clave
