When measuring the quality of a hospital by event rates of certain indications or after specific treatment, it is important to perform a
\nrisk adjustment in order to account for the fact that different hospitals see patients that systematically differ in their characteristics,
\nsuch as age or pre-existing health conditions. One way to summarize the hospital results over such strata is the computation of standardized
\nmortality (or morbidity) ratios (SMRs). <\/p>\n
To take into account statistical effects, SMRs are often reported with confidence intervals.\u00a0 These confidence intervals are usually obtained
\nunder various approximations.\u00a0 For small ratios, Poisson confidence intervals can be obtained.\u00a0 When the confounding risk factors vary
\nonly little among patients, binomial confidence intervals (exact or Wilson) can be used.\u00a0 Asymptotic confidence intervals based on the
\nnormal distribution have also been proposed. <\/p>\n
We follow an approach by Clay and compute exact confidence intervals for SMRs based on the Poisson binomial distribution. We compare the
\ncoverage of such intervals with existing procedures.<\/p>\n","protected":false},"excerpt":{"rendered":"
