Comparative Study
The standardised mortality ratio is unreliable for assessing quality of care in rectal cancer.
The standardised mortality ratio (SMR) for rectal or anal cancer was above average in a large tertiary referral centre for locally advanced rectal cancer in the Netherlands. The aim of this study was to investigate whether the increased SMR was indeed related to poor quality of care or whether it could be explained by inadequate adjustment for case-mix factors. ⋯ The increased SMR appeared to be caused by the admission of patients who received palliative care only. Consequently, the SMR is unreliable for the assessment of quality of care in patients with rectal or anal cancer.
