Attitudes to viability of preterm infants and their effect on figures for perinatal mortality.

Abstract: mation avaailable to us; and many staff of the Medical Research Council Environmental Epidemiology Unit for their help, particularly Mick Merwood for computer analyses and Gill Strange for preparing the manuscript. Professor Geoffrey Rose kindly commented on an earlier version of the paper. The study was approved by the British Medical Association ethical committee and the West Cumbria ethics of research committee and was supported partially by a grant from the Department of Health. 1 Black D.

“…Stillborn babies less than 24 weeks are not registered as deaths, whereas live births are, even though these neonates are generally not resuscitated. Hospitals vary in their propensity to search for life signs 10 . As births to certain ethnic groups were concentrated in particular hospitals, this could produce spurious differences in preterm delivery.…”

“…Since the 1980s, advances in neonatal care have dramatically improved the chances of survival for infants born very preterm (Tin et al, 1997). Thus, infants delivered at gestations below 28 weeks (the gestational age cut-off for inclusion in the study as a late foetal death) may now be more likely to be considered viable, actively resuscitated, and registered as live births, when previously they might have been unregistered foetal losses (Fenton et al, 1990). This might be expected to result in an artefactual increase in live births at very low birthweight.…”

“…All countries use some threshold, in terms of gestational age or birthweight, for registering stillbirths, and some use a threshold for registering live births, and hence deaths among them, as well. Despite the fact that in the 1980s and 1990s these criteria shifted to lower gestational age and birthweight cutoff points in several countries, they still differ substantially between countries 7,8 . Although many studies have now pointed to this problem, its quantitative impact on comparisons of published perinatal mortality rates is largely unknown 9 , except for a study from the late 1980s focusing on the effect of introducing a common lower threshold for birthweight 10 .…”
