In conclusion, in a country with a highly developed social and antenatal maternity healthcare security system giving cost-free maternity and obstetric care to all pregnant women, adolescents had a decreased risk

for adverse obstetric and neonatal outcome compared with the reference group. In the same social context childbirth sellectchem at advanced maternal age was associated with a number of serious complications for the woman as well as the child. For clinicians counselling young mothers it is of great importance to highlight the positive consequences that less obstetric complications and favourable neonatal outcomes are expected. The results imply that there is a need for individualising the antenatal surveillance programmes and obstetric care based on age grouping in order to attempt to improve

the outcomes in the age groups with less favourable obstetric and neonatal outcomes. Such changes in surveillance programmes and obstetric interventions need to be evaluated in further studies.

Electronic health record (EHR) systems can potentially reduce communication problems associated with paper-based transmission of test results.1 2 Computer-based test results can be transmitted securely and instantaneously to providers’ EHR inboxes as ‘alerts’, reducing turnaround time to follow-up.3 Although EHRs appear to reduce the risk of missed test results,2 4 5 they do not eliminate the problem.2 3 6 Lack of timely follow-up of test results remains a major patient safety concern in most healthcare organisations.7–9 AV-951 Previous work has shown that test result follow-up failures can be traced to ambiguity among providers about responsibility for follow-up,10–12 perceived ‘information overload’ among providers who receive large amounts of information electronically,13 and the concurrent use of paper-based and EHR systems to order and report test results.1 14 Other test result management practices may also facilitate or thwart timely follow-up. For instance, we found remarkable differences in rates of abnormal pathology result follow-up between two US Department of Veterans Affairs (VA) healthcare facilities, despite their use of a common EHR system.
