Are mortality rates for different operations related?: implications for measuring the quality of noncardiac surgery.
BACKGROUND Except in cardiac surgery, measuring quality with procedure-specific mortality rates is unreliable because of small sample sizes at individual hospitals. Statistical power can be improved by combining mortality data from multiple operations. We sought to determine whether this approach would still be useful in understanding performance with individual procedures. METHODS We studied...
متن کاملA Gravity Model of Mortality Rates for Two Related Populations
The mortality rate dynamics between two related but different-sized populations are modeled consistently using a new stochastic mortality model that we call the gravity model. The larger population is modeled independently, and the smaller population is modeled in terms of spreads (or deviations) relative to the evolution of the former, but the spreads in the period and cohort effects between t...
متن کاملSex Ratio at Birth and Mortality Rates Are Negatively Related in Humans
Evolutionary theory posits that resource availability and parental investment ability could signal offspring sex selection, in order to maximize reproductive returns. Non-human studies have provided evidence for this phenomenon, and maternal condition around the time of conception has been identified as most important factor that influence offspring sex selection. However, studies on humans hav...
متن کاملDecreases in Smoking-Related Cancer Mortality Rates Are Associated with Birth Cohort Effects in Korean Men
Background: This study aimed to examine trends in smoking-related cancer mortality rates and to investigate the effect birth cohort on smoking-related cancer mortality in Korean men. Methods: The number of smoking-related cancer deaths and corresponding population numbers were obtained from Statistics Korea for the period 1984-2013. Joinpoint regression analysis was used to detect changes in tr...
متن کاملVisual impairment and mortality: are they related?
In this issue of the Journal of the Chinese Medical Association, we have included an article from the Shihpai Eye Study. Therein, Kuang et al reported the relationship between visual impairment and 3-year mortality among older people in the Shihpai area in the city of Taipei. The association between visual impairment and mortality has been extensively studied over a lengthy period of time. The ...
