Working Papers in this series are preliminary materials circulated for review and comment. The views expressed are the author's and do not necessarily represent the position of the Social Security Administration. Summary In this paper I use the 1973 cross-sectional Current Population Survey (CPS) matched to longitudinal Social Security administrative data (through 1998) to examine the relations...

interest. Th e evaluation of the association between the early administration of corticosteroids and mortality in patients with septic shock is extremely important. Th e authors demonstrated that the median time to steroid initiation was shorter in survivors and mortality rates increased with increasing quintiles of time until the initia tion of steroids. Th e authors correctly note the limita ...

background: preterm birth (ptb) is responsible for 70% of neonatal mortalities. various factors influence the risk of neonatal mortality in different populations. objective: our objective was to evaluate neonatal survival rate of preterm infants, and to define its predictors in iranian population. materials and methods: this retrospective cohort study included all preterm (26-37 weeks) infants ...

OBJECTIVE To assess additional risk of newborn death owing to early discharge. METHODS This was a historical cohort study using Washington State linked birth certificates, death certificates, and hospital discharge records that covered 47,879 live births in 1989 and 1990. Logistic regression was used to assess risk of death within the first year of life after early discharge (less than 30 hou...

In this study, the authors identified maternal and child characteristics that were independent predictors of death from infectious diseases acquired in the community and determined if these factors could be used to identify groups of children with excess risk of mortality from infection. A historical cohort study was conducted of children less than 5 years of age between 1985 and 1994 (the stud...

Analysis of early deaths after stroke is important, since some deaths may be preventable. Previous studies have relied on retrospective and often incomplete clinical data, for comparison with pathological findings. The present study is based on 1073 consecutive stroke patients admitted to an intensive care stroke unit from a well-defined population. There were 212 deaths within the first 30 day...

OBJECTIVES Pneumococcal bacteraemia carries a mortality of about 20%. Approximately 50% of deaths from pneumococcal bacteraemia occur within the first 48 h of admission. In order to influence outcome, critically ill patients should be identified at the time of presentation. This study enables the clinician to rapidly make an evidence-based assessment of a patient's prognosis, allowing the ident...
