CONTEXT Measures of physical and cognitive function are strong prognostic predictors of hospital outcomes for older persons, but current risk adjustment and burden of illness assessment indices do not include these measures. OBJECTIVE To evaluate and validate the contribution of functional measures to the ability of 5 standard burden of illness indices(More)
We use a rational expectations model to examine how public disclosure requirements affect listing decisions by rent-seeking corporate insiders, and allocation decisions by liquidity traders seeking to minimize trading costs. We find that exchanges competing for trading volume engage in a 'race for the top' whereunder disclosure requirements increase and(More)
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)
Using 26 cadaver shoulders, we produced a standard defect in the supraspinatus tendon and performed one of three types of repair. Their strength was found by testing in tension the force required to produce a gap of 3 mm, then 6 mm, and finally total disruption of the repair. The use of a polyethylene patch to spread the forces over the lateral bone surface(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)
OBJECTIVES Both low-level mupirocin resistance (LMR) and high-level mupirocin resistance (HMR) have been identified. The aim of this study was to determine the epidemiology of LMR and HMR in MRSA isolates at five hospitals that have used mupirocin for targeted decolonization as part of successful institutional control programmes. METHODS All MRSA(More)
