DECISION SUPPORT SYSTEM FOR HOSPITAL QUALITY ASSESSMENT
First Claim
1. A machine-executable process for computing reference and benchmark data for evaluating healthcare providers comprises:
- obtaining at least two data sets including a first data set, and a second data set, wherein;
the first data set includes present on admission data that represents a condition of a patient that is present at the time an order for inpatient admission occurs; and
the second data set does not require present on admission data;
establishing quality measures including obtaining a set of quality indicators;
evaluating each of the first data set and the second data set against the obtained quality indicators;
calibrating, by a processor, the expected present on admission data of the first data set as a Recalibration Factor such that an overall observed rate (P) equals an overall expected rate (E[P|X]) for each quality measure of the first data set;
using, by the processor, the Recalibration Factor to calculate expected present on admission data on the second data set;
using the calculated expected present on admission data of the second data set to calculate an observed and expected outcome of interest on the second data set;
using the calculated observed and expected outcome of interest of the second data set to forecast an observed and expected outcome of interest for the second data set;
using the calculated observed and expected outcome of interest on the second data set and the forecasted observed and expected outcome of interest on the second data set to calculate an overall observed-to-expected ratio and a reference population rate (K) for each quality measure of the second data set; and
using a predetermined signal variance and the reference population rate on the second data set to calculate a national benchmark for each quality measure.

Abstract
A decision support system comprises receiving a request from a client computer to derive a quality assessment associated with a health care provider of interest, receiving an identification of a user-selected benchmark, determining a comparison range over which data from the data source is to be analyzed, identifying a set of quality measures, generating a first data set of quality measure performance by evaluating the set of quality measures against underlying medical data in a data source filtered by the range, generating a second data set defining an estimated quality measure performance using a probabilistic forecasting model to evaluate the set of quality measures by drawing inferences about the set of quality measures beyond a period of time for which the underlying medical data is available. An overall quality indicator score is computed, based upon a comparison of the first data set and the second data set.
