The final step in the selection was to discard 1 239 pati<strong>en</strong>ts who had un<strong>de</strong>rgone two<br />

THR during two consecutive hospitalizations in the period 2004-2005. This was done to<br />

avoid confusion in id<strong>en</strong>tifying and allocating adverse ev<strong>en</strong>ts. The final p<strong>op</strong>ulation<br />

comprised only pati<strong>en</strong>ts with one THR in 2004-2005. The <strong>volume</strong> per hospital was thus<br />

<strong>de</strong>rived from this selection of stays.<br />

Results of <strong>de</strong>finition: 11 856 stays with one elective total hip replacem<strong>en</strong>t<br />

were selected (for 11 856 pati<strong>en</strong>ts).
