Abstract Background Clostridioides difficile infection (CDI), especially recurrent CDI (rCDI), is associated with high morbidity and resource use and imposes a significant burden on the US healthcare system. The objective of this study was to evaluate the burden of rCDI on healthcare resource utilization. Methods A retrospective study analyzed commercial claims data from patients aged 18–64 years old in the IQVIA PharMetrics Plus™ database. CDI episodes required an inpatient stay with CDI diagnosis code (ICD-9-CM 008.45; ICD-10-CM A04.7, A04.71, A04.72), or an outpatient medical claim with CDI diagnosis code plus a CDI treatment, and index episodes occurred from January 1, 2010 to June 30, 2017. Only patients who were observable 6 months before and 12 months after the index CDI episode were included. Each CDI episode was followed by a 14-day claim-free period after the end of treatment. rCDI was defined as another CDI episode within an 8-week window immediately after the claim-free period. Number of CDI and rCDI episodes, healthcare resource use, and costs were calculated over 12-month follow-up and stratified by number of rCDI episodes. Costs were adjusted to 2018 dollars. Results 46,571 patients with an index CDI episode were included, with 3,129 (6.7%) who had 1 rCDI, 472 (1.0%) who had 2 rCDI, and 134 (0.3%) who had 3+ rCDI episodes. Mean age was 47.4 years, and 62.4% were female. In the 12-month follow-up, the mean (SD) numbers of inpatient visits were 1.4 (2.1) for those with no rCDI, 2.7 (3.4) for those with 1 rCDI, 3.7 (3.9) for those with 2 rCDI, and 5.8 (6.0) for those with 3+ rCDI episodes. Emergency department (ED) visits had a similar trend, with mean (SD) number of visits of 1.5 (3.5), 2.5 (6.0), 3.7 (7.0), and 4.6 (13), respectively for the four study groups. All-cause costs after the index CDI were $71,980 for those with no rCDI, $131,953 for those with 1 rCDI, $180,574 for those with 2 rCDI, and $207,733 for those with 3+ rCDI. Conclusion CDI and rCDI are associated with substantial healthcare resource utilization and direct medical costs. During the 12 months after an index CDI episode, the number of inpatient admissions and ED visits increased substantially for patients with an rCDI episode. Direct medical costs for patients with rCDI also increased with number of recurrences. Disclosures All authors: No reported disclosures.

IntroductionAnti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) is a rare, serious and often life-threatening disease. The use of available treatments options (immunosuppressants and glucocorticoids (GCs)) improves the prognosis of AAV greatly; however, GC use is associated with significant toxicity related morbidities and the management of AAV is costly. However, information of the costs associated with AAV in the United Kingdom is limited. This study aimed to quantify the burden of AAV using a large England and Wales source of real-world data, the Clinical Practice Research Datalink (CPRD) Hospital Episode Statistics (HES) linked database, to identify healthcare resource utilization and generate estimates of costs.MethodsIncident patients (n = 220) were included if ≥ eighteen years, with diagnosis read codes G754.00/G75A.00; ICD codes M31.3/M31.7 from January 1997 to December 2017. Costs were taken from Unit Costs of Social and Health Care, National Health Service reference costs and electronic drug tariff. Distinction was made between type of consultations, outpatient visits and inpatient admission based on Healthcare Resource Grouping. Costs were summarised as mean per member per year (PMPY) in 2016 prices and presented before and after diagnosis.ResultsIn the year preceding AAV diagnosis, mean costs PMPY were GBP12,012 [USD15,400], (GBP5,339 [USD6,845] inpatient, GBP766 [USD982] outpatient, GBP314 [USD403] GP, GBP5,594 [USD7,172] GP prescribing). In the year of AAV diagnosis (Y0) costs PMPY were GBP28,252 [USD36,220], GBP15,436 [USD19,790] inpatient, GBP1,863 [USD2,388] outpatient, GBP2,407 [USD3,086] GBP8,545 [USD10,956] GP prescribing). Costs in the years post-diagnosis remained higher than pre-diagnosis with a low of GBP22,839 [USD29,281] in Y4. The prescribing costs (GC, methotrexate and azathioprine) were the largest contributor in Y0-Y4 (GBP15,047 [USD19,291] Y1; GBP12,325 [USD15,801] Y4).ConclusionsDiagnosis of AAV is associated with increased healthcare costs, including higher inpatients costs in the year of diagnosis and subsequently higher prescribing costs in the community. Given the incidence (17.2 cases per million) and considering only costs in the year of diagnosis, an additional GBP15.6 million [USD24.6 million] of healthcare resource utilization occurs every year from new diagnoses of AAV. However, this will likely be underestimated due to the lack of secondary care prescribing data in CPRD-HES and prescribing of immunosuppressant treatments in this setting.
