Dissecting the compression of mortality in Switzerland, 1876-2005
This paper aims to examine changes in common longevity and variability of the adult life span, and attempts to answer whether or not the compression of mortality continues in Switzerland in the years 1876-2005. The results show that the negative relati
Validation of the Potentially Avoidable Hospital Readmission Rate as a Routine Indicator of the Quality of Hospital Care
BACKGROUND: The hospital readmission rate has been proposed as an important outcome indicator computable from routine statistics. However, most commonly used measures raise conceptual issues. OBJECTIVES: We sought to evaluate the usefulness of the computerized algorithm for identifying avoidable readmissions on the basis of minimum bias, criterion validity, and measurement precision. RESEARCH DESIGN AND SUBJECTS: A total of 131,809 hospitalizatio…
Age at death and rectangularisation of the survival curve
OBJECTIVE: To check if signs of rectangularisation of the survival curve appeared during recent decades in Switzerland--that is, if life expectancy is approaching a maximum with a clustering of age at death around an average value (the so called "compression of mortality"). METHODS: Descriptive analysis of age of death and its trends over 26 years, as characterised by the modal value, median, and various percentiles beyond the median. POPULATION:…
Fitting the Distributions of Length of Stay by Parametric Models
OBJECTIVES: The purpose of this study was to assess the adequacy of three widely used models--Lognormal, Weibull, and Gamma--for describing the distribution of length of stay. This is a fundamental step in the development of outliers resistant (robust) methods for the statistical analysis of this kind of data, where the main objective is to determine measures of average and total resource consumption of groups of patients. Current practice uses s…
