Excerpt
Recent epidemiological studies have contributed important information to a better understanding of intensive care practice and the outcome of our patients. Garrouste-Ortegas et al. [
1] examined the association between body mass index (BMI) and mortality in adult intensive care patients. They divided patients into four groups based on BMI. Although severity of illness at admission was similar between the groups, patients with a BMI lower than 18.5% experienced significantly higher ICU and hospital mortality rates. The authors concluded that BMI could thus be of importance in risk adjustment and recommend including it in the development of future scoring systems. Wunsch et al. [
2] examined the association between day and time of ICU admission and hospital mortality in 102 ICUs in the United Kingdom. They found crude mortality rates to be higher for Saturday and Sunday admissions. After risk adjustment, however, mortality rates were not associated with differences in hospital mortality. Another United Kingdom study, this one by Harrison et al. [
3], analyzed seasonal differences in the mortality of intensive care patients in ICUs. Winter was defined as the period from December to February and nonwinter, thus as the period from March to November. Crude hospital mortality rates were higher during winter. After adjustment for case-mix these differences disappeared. Unit occupancy and workload were not associated with the increased mortality. The excess winter mortality observed in ICUs in the United Kingdom, according to these authors, can thus be explained by variations in case mix and not by seasonal factors. …
