Abstract

Objectives

To evaluate European HRU associated with SREs (radiation to bone [RB], surgery to bone [SB], pathologic fracture [PF], spinal cord compression [SCC]).

Methods

Eligible patients (bone metastases from breast/lung/prostate cancer or multiple myeloma, with an index SRE [defined as an SRE preceded by an SRE-free period of at least 6.5 months] between July 2004 and July 2009) were enrolled from Austria, Czech Republic, Finland, Greece, Poland, Portugal, Sweden and Switzerland (Study:20090146). HRU data were gathered from baseline (pre-index SRE period: 3-month period, beginning 3.5 months pre-index SRE) and post-index SRE period (14-day diagnosis period pre-index SRE to 3 months post-SRE). We present mean (bootstrapped 95% confidence interval [CI]) change in HRU from baseline per index SRE for pooled country data.

Results

The Table presents the mean change from baseline in HRU per index SRE for the pooled data from the 8 European countries included in this study. An increase was observed in all HRU types following the index SRE. Change in overall HRU was predominantly driven by increases in the duration of inpatient stays, with a mean increase of between 7.81 and 22.21 days depending on SRE type. Substantial increases were also seen in the number of procedures and the number of outpatient visits, with mean increases from 5.85 to 9.58 and from 2.58 to 4.24, respectively. Of the index SREs, SCC was associated with the greatest increase in HRU burden for the following HRU types: duration of inpatient stays, emergency room (ER) visits, and procedures.

Conclusions

Overall, SREs are associated with substantial HRU burden. The largest increases in HRU burden were seen following SCC.

Mean (95% CI) change from baseline in HRU according to index SRE type (full analysis set).
