Women's birth place preferences in the United Kingdom: a systematic review and narrative synthesis of the quantitative literature.

backgroundCurrent clinical guidelines and national policy in England support offering 'low risk' women a choice of birth setting, but despite an increase in provison of midwifery units in England the vast majority of women still give birth in obstetric units and there is uncertainty around how best to configure services. There is therefore a need to better understand women's birth place preferences. The aim of this review was to summarise the recent quantitative evidence on UK women's birth place preferences with a focus on identifying the service attributes that 'low risk' women prefer and on identifying which attributes women prioritise when choosing their intended maternity unit or birth setting.

methodsWe searched Medline, Embase, PsycINFO, Science Citation Index, Social Science Index, CINAHL and ASSIA to identify quantitative studies published in scientific journals since 1992 and designed to describe and explore women's preferences in relation to place of birth. We included experimental stated preference studies, surveys and mixed-methods studies containing relevant quantitative data, where participants were 'low risk' or 'unselected' groups of women with experience of UK maternity services.

resultsWe included five experimental stated preference studies and four observational surveys, including a total of 4201 respondents. Most studies were old with only three conducted since 2000. Methodological quality was generally poor. The attributes and preferences most commonly explored related to pain relief, continuity of midwife, involvement/availability of medical staff, 'homely' environment/atmosphere, decision-making style, distance/travel time and need for transfer. Service attributes that were almost universally valued by women included local services, being attended by a known midwife and a preference for a degree of control and involvement in decision-making. A substantial proportion of women had a strong preference for care in a hospital setting where medical staff are not necessarily involved in their care, but are readily available.

conclusionsThe majority of women appear to value some service attributes while preferences differ for others. Policy makers, commissioners and service providers might usefully consider how to extend the availability of services that most women value while offering a choice of options that enable women to access services that best fit their needs and preferences.
