- Abstract
Background: Clostridioides difficile infection (CDI) is a form of antibiotic‐associated infectious diarrhoea resulting in significant morbidity and mortality. Community‐acquired disease in low‐risk individuals is increasingly recognised. There are limited New Zealand data published. Aim: To determine the incidence and location of onset of CDI cases in the Manawatu region, and further describe the demographics, risk factors and prevalent C. difficile ribotypes of the population. Methods: We performed an incidence case–control study of CDI in the Manawatu region between September 2018 and September 2019. Cases were matched to controls with a negative test for C. difficile. Demographic and comorbidity data, location of onset, drug exposure, disease recurrence and 30‐day mortality were collected. Ribotype analysis was performed on C. difficile isolates. Results: Thirty‐two specimens tested toxin positive over 12 months, yielding an incidence of 18.3 cases per 100 000 person‐years. Twenty‐five percent of cases had community onset disease. Cases were more likely to have had amoxicillin/clavulanate or ceftriaxone prescribed. Elevated blood white cell count and lower HbA1c were significantly associated with CDI. The dominant ribotype was 014/020. Two cases were RT 023. Conclusion: Our data are similar to previous national data. RT 023 has not been previously reported in New Zealand and has been associated with severe colitis. We demonstrated a significant proportion of community‐acquired cases and the true incidence might be higher. Vigilance for community onset disease is required. These data may allow observation of temporal changes in incidence and infection patterns of CDI in New Zealand.
