Objective: to explore the views of midwives towards traditional and flexible schedules of antenatal attendance for women at low risk.Design: a qualitative approach using focus groups.Setting: three NHS Trusts providing maternity care in and around Bristol.Sample: 14 midwives who had provided antenatal care to women participating in the Bristol Antenatal Care Study.Findings: midwives generally expressed support for a move away from the traditional schedule of antenatal attendances, suggesting that this represented a move towards the acceptance of pregnancy as a normal life event. They recognised that some women would prefer flexible care and the possibility of a reduction in the number of antenatal attendances. However, they suggested that some women would require additional information in order to feel confident in these circumstances. The midwives also recognised that both they and pregnant women have reservations about reducing contact during the antenatal period. Central to these reservations is a concern that women's psychosocial as well as physical needs may go unmet if antenatal contact is reduced.Implications for practice: although in principle supporting a move away from the traditional schedule of antenatal attendances, the reservations felt by midwives towards a reduction in antenatal attendances are reflected in their practice. These concerns currently impede any radical move away from the traditional schedule of antenatal check-ups and will need to be addressed by midwifery managers prior to the implementation of a more flexible schedule of antenatal attendances, if any such change is to be sustainable. 相似文献

Just as metabolites, hormones and proteins are measured in newborn screening tests, DNA has become an analyte that is important in the screens for certain disorders. DNA confirmatory testing on the original dried blood specimen reduces the age at diagnostic confirmation and antibiotic prophylaxis initiation for neonates with sickle cell disease. Molecular genetic analysis of the initial specimens from newborns with elevated immunoreactive trypsinogen (IRT) for cystic fibrosis (CF) screening permits reduction of the IRT threshold value, improving specificity without compromising sensitivity. Because of this cost reduction, CF neonatal screening programs routinely incorporate DNA confirmatory testing into their initial CF screening algorithm. DNA analysis is also a valuable adjunct in screening programs for congenital adrenal hyperplasia (CAH), improving sensitivity and specificity. Incorporation of DNA into newborn screening programs will continue to be stimulated by development of robust, high throughput technologies for evaluation of this analyte. New paradigms for neonatal screening are evolving, including hearing screening in the newborn nursery. DNA testing, such as for mutations in the connexin 26 gene, may have a role in the evaluation of those screened positive. Newborn screening dried blood specimens are DNA databases. Therefore, there are significant ethical, legal and social issues that must be considered in the storage and utilization of neonatal screening specimens. 相似文献

Helping frail and vulnerable individuals and their families to make the best health-related decision is difficult even in the best of circumstances. Decision-making as a discrete action is often discussed in the health care literature, but the concept that decision-making is a process is largely ignored. Understanding the basic elements of the decision-making process used by older adults and their family, or support individual(s) may help health care team members offer more substantial and meaningful assistance to the individuals who are trying to make tough health-related decisions. Full information needs to be available so all participants involved in the process can make reasonable decisions. The decision-making process is highly contextual and is based on how realistic the decision-making goals are and how congruent the experiences versus perceived expectations are, as well as the quality of options available. 相似文献
