After a steady increase since the 1950s, laryngeal cancer mortality had tended to level off since the early 1980s in men from most European countries. To update trends in laryngeal cancer mortality in Europe, age-standardized (world standard) mortality rates per 100,000 were derived from the WHO mortality database for 33 European countries over the period 1980-2001. Jointpoint analysis was used to identify significant changes in mortality rates. ⋯ Laryngeal cancer mortality was comparatively low in women from most European countries, with stable rates around 0.3/100,000 in the EU as a whole over the last 2 decades. Laryngeal cancer trends should be interpreted in terms of patterns and changes in exposure to alcohol and tobacco. Despite recent declines, the persistence of a wide variability in male laryngeal cancer mortality indicates that there is still ample scope for prevention of laryngeal cancer in Europe.

Death rates are an outcome that can be used to describe a service. We measured three death rates that can be used to describe an emergency department (ED): death rates for those seen in the ED and discharged, those that die within the ED, and those that die after admission. We also wanted to establish how easy it was to obtain these rates and how frequently autopsy was performed. ⋯ These three death rates were easy to calculate and could be used to describe the outcome of an ED service. Further research to establish the range of rates for different departments is now required to determine their potential use.

Although morbidity is high in prisoners compared with the general population, uncertainty exists over rates for natural causes of death. We investigated natural deaths in prisons in England and Wales over a 20-year period. ⋯ There are important methodological challenges in calculating SMRs in prisoners. Bearing these in mind, we found increased mortality ratios for respiratory pneumonia and other infections. These findings highlight the need for the screening and effective treatment of infectious diseases in prisoners.

Benchmarking performance in organ donation programs: dependence on demographics and mortality rates.
Donors whose diagnosis of death is based upon neurologic criteria are the primary source of organs for human transplantation. The current measure of effectiveness of organ donation programs is the crude statistic, donors per million population (DPMP). This statistic represents the number of available donors, divided by the potential donor population. Comparisons between transplantation programs are done using the DPMP statistic. We sought to determine if variance in organ donation rates, reported as DPMP could be accounted for by differences in population demographics, specifically age and gender-specific mortality rates. ⋯ These results bring into question the reliability of using crude DPMP as a measure of organ and tissue donation program performance. Alternative measures of benchmarking performance in organ donation programs should be considered.
