Currently, analyses of readmissions are based on a logistic\u2013normal generalized linear mixed model that permits estimation of hospital-specific measures while adjusting for case mix differences. Recent moves to identify and address healthcare disparities call for expanding case mix adjustment to include measures of socio-economic status while minimizing additional burden to hospitals associated with collecting data on such measures. Towards resolving this dilemma, we propose that detailed socio-economic data be collected on a subsample of patients via an outcome-dependent sampling scheme, specifically the cluster-stratified case\u2013control design. Estimation and inference, for both the fixed and the random-effects components, are performed via pseudo-maximum-likelihood wherein inverse probability weights are incorporated in the usual integrated likelihood to account for the design. In comprehensive simulations, cluster-stratified case\u2013control sampling proves to be an efficient design whenever interest lies in fixed or random effects of a generalized linear mixed model and covariates are unobserved or expensive to collect. The methods are motivated by and illustrated with an analysis of N = 889661 Medicare beneficiaries hospitalized between 2011 and 2013 with congestive heart failure at one of K = 3116 hospitals. Results highlight that the framework proposed provides a means of mitigating disparities in terms of which hospitals are indicated as being poor performers, relative to a naive analysis that fails to adjust for missing case mix variables.<\/jats:p>","DOI":"10.1111\/rssa.12503","type":"journal-article","created":{"date-parts":[[2019,8,30]],"date-time":"2019-08-30T01:00:56Z","timestamp":1567126856000},"page":"379-402","source":"Crossref","is-referenced-by-count":7,"title":["Outcome-Dependent Sampling in Cluster-Correlated Data Settings with Application to Hospital Profiling"],"prefix":"10.1093","volume":"183","author":[{"given":"Glen","family":"McGee","sequence":"first","affiliation":[{"name":"Harvard T.H.
