Drivers of Healthcare resource Utilization and factors associated with increased resource use in Patients with Fibromyalgia: an evaluation using Electronic Medical Records

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.

Objective: Individuals' recollections of the number and type of health service encounters are frequently required for health economic studies. We sought to establish whether the accuracy of self-reported healthcare resource utilization is a function of the duration of the recall period and the saliency of the health service encounter.Methods: Patient recollections of a range of community services (general practitioner visits, community midwifery visits) and hospital services (accident and emergency attendances, hospital outpatient attendances, inpatient admissions) over 4-month and 8-month time periods were obtained from women participating in a randomized controlled trial. Comparisons were made with healthcare resource utilization data extracted from medical records. Where significant differences were identified between the self-reported and medically recorded data, a multivariate linear regression model was constructed to identify the factors associated with underreporting and overreporting of healthcare resource utilization.Results: The study revealed a tendency to underreport community service utilization, which appears to be exacerbated when the recall period is extended. A number of sociodemographic and clinical factors significantly associated with this tendency to underreport community service utilization were identified. The self-reporting of hospital service utilization over varying periods of recall was found to be more accurate.Conclusion: It is important that economic analysts establish optimal methods for estimating resource utilization quantities within health economic analytical designs. In particular, greater emphasis should be placed on extracting information on community service utilization from medical records or routine health service information systems.
