Some 15·9 (95 per cent confidence interval (c.i.) 14·2 to 17·6) per cent of these patients had an APR. Among 707 people with low rectal cancer, 38·2 (34·6 to 41·8) per cent underwent APR. Although risk‐adjusted hospital rates of APR for low rectal cancer varied by up to 100 per cent, only one hospital (1 per cent) fell outside funnel plot limits and hospital variance in multilevel models was not very large. Lower hospital rates of APR for low rectal cancer did not correlate significantly with better hospital‐level outcomes or process measures, except for recording of pathological stage (<italic>r</italic> = −0·55, <italic>P</italic> = 0·019). Patients were significantly more likely to undergo APR for low rectal cancer if they attended a non‐tertiary metropolitan hospital (adjusted odds ratio 2·14, 95 per cent c.i. 1·11 to 4·15)</bold>.</p> </sec> <sec id="bjs9293-sec-0004" sec-type="section"> <title>Conclusion</title> <p id="bjs9293-para-0004"> <bold>APR rates do not appear to be a useful surrogate marker of overall hospital performance in rectal cancer surgery</bold>.</p> </sec> </abstract>
