The potentially preventable readmission (PPR) method uses administrative data to identify hospital readmissions that may indicate problems with quality of care. The PPR logic determines whether the reason for readmission is clinically related to a prior admission, and therefore potentially preventable. The likelihood of a PPR was found to be dependent on(More)
This article describes the development of Potentially Preventable Complications (PPCs), a new method that uses a present on admission (POA) indicator to identify in-hospital complications among secondary diagnoses that arise after admission. Analyses that used PPCs to obtain risk-adjusted complication rates for California hospitals showed that (1) the POA(More)
Under the Medicare diagnosis-related group (DRG) based inpatient prospective payment system (IPPS), payments to hospitals can increase when a post-admission complication occurs. This article proposes a redesign of IPPS that reduces, but does not eliminate, the increase in payment due to post-admission complications. Using California data that contained a(More)
A redesign of the Medicare inpatient prospective payment system (IPPS) that reduces payments to hospitals that have high-risk adjusted readmission rates is proposed. The redesigned IPPS uses a readmission performance standard from best practice hospitals to determine the risk-adjusted number of excess readmissions in a hospital and determines the payment(More)
Clinical risk-adjustment, the ability to standardize the comparison of individuals with different health needs, is based upon 2 main alternative approaches: regression models and clinical categorical models. In this article, we examine the impact of the differences in the way these models are constructed on end user applications.
Payment reforms aimed at linking payment and quality have largely been based on the adherence to process measures. As a result, the attempt to pay for value is getting lost in an overly complex attempt to measure value. The "Incentivizing Health Care Quality Outcomes Act of 2014" (HR 5823) proposes to replace the existing patchwork of process and outcomes(More)
Proposals to make complexity-of-illness adjustments to the diagnosis-related group system have relied on secondary diagnosis codes and additional clinical information obtained from the hospital record. Another potential mechanism for modifying diagnosis-related groups involves the use of non-operating room procedure codes. The use of these codes has the(More)
