Observational studies comparing groups or populations to evaluate services or interventions usually require case-mix adjustment to account for imbalances between the groups being compared. Simulation studies have, however, shown that case-mix adjustment can make any bias worse. One reason this can happen is if the risk factors used in the adjustment are related to the risk in different ways in ...
The market-oriented health care reforms taking place in the Netherlands show a clear resemblance to the proposals for managed competition in U.S. health care. In both countries good risk adjustment mechanisms that prevent cream skimming--that is, that prevent plans from selecting the best health risks--are critical to the success of the reforms. In this paper we present an overview of the Dutch...
BACKGROUND AND OBJECTIVE There is a lack of broadly applicable measures for risk adjustment in pediatric surgical patients necessary for improving outcomes and patient safety. Our objective was to develop a risk stratification model that predicts mortality after surgical operations in children. METHODS The model was created by using inpatient databases from 1988 to 2006. Patients younger than...
A commonly used method for evaluating a hospital's performance on an outcome is to compare the hospital's observed outcome rate to the hospital's expected outcome rate given its patient (case) mix and service. The process of calculating the hospital's expected outcome rate given its patient mix and service is called risk adjustment (Iezzoni 1997). Risk adjustment is critical for accurately eval...
INTRODUCTION Effective risk adjustment is an aspect that is more and more given weight on the background of competitive health insurance systems and vital healthcare systems. The objective of this review was to obtain an overview of existing models of risk adjustment as well as on crucial weights in risk adjustment. Moreover, the predictive performance of selected methods in international healt...
This paper analyzes some of the perverse incentives that may arise under the current Medicare prescription drug benefit design. In particular, risk adjustment for a stand-alone prescription drug benefit creates perverse incentives for prescription drug plans when making coverage decisions and/or for pharmaceutical companies when setting prices. This problem is new in that it does not arise with...
OBJECTIVES/HYPOTHESIS To characterize the frequency and nature of readmissions to free standing pediatric hospitals after otolaryngologic procedures. STUDY DESIGN Retrospective national database analysis. METHODS Using the Pediatric Health Information Systems database, we examined 30-day inpatient readmissions in children less than 18 years old who underwent otolaryngology procedures betwee...
Health outcomes evaluation seeks to compare a new treatment or novel programme with the current standard of care, or to identify variation of outcomes across different healthcare providers. In the real world, it is not always possible to conduct randomised controlled trials to address the issue of comparator groups being different with respect to baseline risk factors for the outcomes. Therefor...
BACKGROUND Adolescence is associated with developments in the reward system and increased rates of emotional disorders. Familial risk for depression may be associated with disruptions in the reward system. However, it is unclear how symptoms of depression and anxiety influence the development of reward-processing over adolescence and whether variation in the severity of parental depression is a...
BACKGROUND Caesarean delivery (CD) rates are commonly used as an indicator of quality in obstetric care and risk adjustment evaluation is recommended to assess inter-institutional variations. The aim of this study was to evaluate whether the Ten Group classification system (TGCS) can be used in case-mix adjustment. METHODS Standardized data on 15,255 deliveries from 11 different regional cent...
