Reliability of hospital cost profiles in inpatient surgery.
This study sought to discover whether Medicare payments for surgery can reliably compare hospital costs. It found that episode payments for inpatient surgery are a reliable measure of hospital costs for commonly performed procedures, but are less reliable for lower volume operations. These findings suggest that hospital cost profiles based on Medicare claims data may be used to benchmark efficiency, especially for more common procedures.

Risk-adjusted in-hospital mortality models for congestive heart failure and acute myocardial infarction: Value of clinical laboratory data and race/ethnicity.
This study examined the impact of key laboratory and race/ethnicity data on the prediction of in-hospital mortality for congestive heart failure (CHF) and acute myocardial infarction (AMI). It found that adding a simple three-level summary measure based on the number of abnormal laboratory data observed to hospital administrative claims data significantly improved the model prediction for inpatient mortality.

Validity of deterministic record linkage using multiple indirect personal identifiers: linking a large registry to claims data.
The researchers compared the validity of several deterministic record linkage methods with multiple indirect identifiers by using data from the Centers for Medicare and Medicaid Services (CMS) implantable cardioverter-defibrillator (ICD) registry and administrative Medicare inpatient claims data. Linkage rules using 2 or 3 indirect, patient-level identifiers and hospital ID produced linkages with sensitivity of 95% and specificity of 98% compared with a gold standard linkage rule.
