Health resource utilization associated with skeletal-related events: results from a retrospective European study

Background Bone complications, also known as skeletal-related events (SREs), are common in patients with bone metastases secondary to advanced cancers. Objective To provide a detailed estimate of the health resource utilization (HRU) burden associated with SREs across eight European countries. Methods Eligible patients from centers in Austria, the Czech Republic, Finland, Greece, Poland, Portugal, Sweden, and Switzerland with bone metastases or lesions secondary to breast cancer, prostate, or lung cancer or multiple myeloma who had experienced at least one SRE (defined as radiation to bone, long-bone pathologic fracture, other bone pathologic fracture, surgery to bone or spinal cord compression) were entered into this study. HRU data were extracted retrospectively from the patients' charts from 3.5 months before the index SRE until 3 months after the index SRE (defined as an SRE preceded by an SRE-free period of at least 6.5 months). Results Overall, the mean number of inpatient stays per SRE increased from baseline by approximately 0.5-1.5 stays, with increases in the total duration of inpatient stays of approximately 6-37 days per event. All SREs were associated with substantial increases from baseline in the frequency of procedures and the number of outpatient and day-care visits. Conclusions SREs are associated with substantial HRU owing to considerable increases in the number and duration of inpatient stays, and in the number of procedures, outpatient visits, and day-care visits. These data collectively provide a valuable summary of the real-world SRE burden on European healthcare systems.
