Resource description

In order to address the problem of poor quality information available to health care providers today, McClellan and Staiger (1999) developed a new method to measure quality, which addresses some key limitations of other approaches. Their method produces quality estimates that reflect different dimensions of quality and are able to eliminate systematic bias and noise inherent in these types of measures. While these measures are promising indicators, they have not been applied to other conditions or health systems since their publication. This paper attempts to replicated their 1999 method by calculating these quality measures for English Hospitals using Hospital Episode Statistics for the years 1996-2008 for Acute Myocardial Infarction (AMI) and Hip Replacement. Using the latent outcome measures calculated previously, Vector Autoregressions (VARs) are used to combine the information from different time periods and across measures within each condition. These measures are then used to compare current and past quality of care within and across NHS Acute Trusts. Our results support that this method is well suited to measure and predict provider quality of care in the English setting using the individual patient level data collected.
