A national survey of obstetric early warning systems in the United Kingdom: five years on.

The Confidential Enquiries into Maternal Deaths in the UK have recommended obstetric early warning systems for early identification of clinical deterioration to reduce maternal morbidity and mortality. This survey explored early warning systems currently used by maternity units in the UK. An electronic questionnaire was sent to all 205 lead obstetric anaesthetists under the auspices of the Obstetric Anaesthetists' Association, generating 130 (63%) responses. All respondents reported use of an obstetric early warning system, compared with 19% in a similar survey in 2007. Respondents agreed that the six most important physiological parameters to record were respiratory rate, heart rate, temperature, systolic and diastolic blood pressure and oxygen saturation. One hundred and eighteen (91%) lead anaesthetists agreed that early warning systems helped to prevent obstetric morbidity. Staffing pressures were perceived as the greatest barrier to their use, and improved audit, education and training for healthcare professionals were identified as priority areas.

Vital signs and other observations used to detect deterioration in pregnant women: an analysis of vital sign charts in consultant-led UK maternity units.

BACKGROUND: Obstetric early warning systems are recommended for monitoring hospitalised pregnant and postnatal women. We decided to compare: (i) vital sign values used to define physiological normality; (ii) symptoms and signs used to escalate care; (iii) type of chart used; and (iv) presence of explicit instructions for escalating care. METHODS: One-hundred-and-twenty obstetric early warning charts and escalation protocols were obtained from consultant-led maternity units in the UK and Channel Islands. These data were extracted: values used to determine normality for each maternal vital sign; chart colour-coding; instructions following early warning system triggering; other criteria used as triggers. RESULTS: There was considerable variation in the charts, warning systems and escalation protocols. Of 120 charts, 89.2% used colour; 69.2% used colour-coded escalation systems. Forty-one (34.2%) systems required the calculation of weighted scores. Seventy-five discrete combinations of 'normal' vital sign ranges were found, the most common being: heart rate=50-99beats/min; respiratory rate=11-20breaths/min; blood pressure, systolic=100-149mmHg, diastolic ≤89mmHg; SpO2=95-100%; temperature=36.0-37.9°C; and Alert-Voice-Pain-Unresponsive assessment=Alert. Most charts (90.8%) provided instructions about who to contact following triggering, but only 41.7% gave instructions about subsequent observation frequency. CONCLUSION: The wide range of 'normal' vital sign values in different systems suggests a lack of equity in the processes for detecting deterioration and escalating care in hospitalised pregnant and postnatal women. Agreement regarding 'normal' vital sign ranges is urgently required and would assist the development of a standardised obstetric early warning system and chart.

Redesigning postnatal care: a randomised controlled trial of protocol-based midwifery-led care focused on individual women's physical and psychological health needs.

OBJECTIVES: To develop, implement and test the cost-effectiveness of redesigned postnatal care compared with current care on women's physical and psychological health. DESIGN: A cluster randomised controlled trial, with general practice as the unit of randomisation. Recruited women were followed up by postal questionnaire at 4 and 12 months postpartum and further data collected from midwife and general practice sources. SETTING: Thirty-six randomly selected general practice clusters in the West Midlands Health Region, UK. PARTICIPANTS: All women expected to be resident within recruited practices for postnatal care were eligible for inclusion. Attached midwives recruited 1087 women in the intervention and 977 in the control practice clusters. INTERVENTIONS: The systematic identification and management of women's health problems, led by midwives with general practitioner contact only when required. Symptom checklists and the Edinburgh Postnatal Depression Scale (EPDS) were used at various times to maximise the identification of problems, and individual care and visit plans based on needs. Evidence-based guidelines were used to manage needs. Care was delivered over a longer period. MAIN OUTCOME MEASURES: Women's health at 4 and 12 months, assessed by the Physical and Mental Component Scores (PCS and MCS) of the Short-Form 36 (SF-36) and the EPDS. Women's views about care, reported morbidity at 12 months, health service usage during the year, 'good practice' indicators and health professionals' views about care were secondary outcomes. RESULTS: At 4 and 12 months postpartum the mean MCS and EPDS scores were significantly better in the intervention group and the proportion of women with an EPDS score of 13+ (indicative of probable depression) was significantly lower relative to controls. The physical health score (PCS) did not differ. Health service usage was significantly less in the intervention group as well as reported psychological morbidity at 12 months. Women's views about care were either more positive or did not differ. Intervention midwives were more satisfied with redesigned care than control midwives were with standard care. Intervention care was cost-effective since outcomes were better and costs did not differ substantially. CONCLUSIONS: The redesigned community postnatal care led by midwives and delivered over a longer period, resulted in an improvement in women's mental health at 4 months postpartum, which persisted at 12 months and at equivalent overall cost. It is suggested that further research should focus on: the identification of postnatal depression through screening; whether fewer adverse longer term effects might be demonstrated among the children of the women who had the intervention care relative to the controls; testing interventions to reduce physical morbidity, including studies to validate measures of physical health in postpartum women. Further research is also required to investigate appropriate postnatal care for ethnic minority groups.

Attendance, content and relevance of the six week postnatal examination.

OBJECTIVE: to describe the attendance and content of the six week postnatal examination, and associate the examinations performed with relevant delivery factors and postpartum symptoms. DESIGN: survey of 1278 women who responded to a postal questionnaire sent 6-7 months after delivery, as part of a wider study investigating the severity, effect and extent of long-term health problems after childbirth. Questions about attendance and content of the postnatal examination were included. Data obtained from the women were linked to the obstetric case notes. SETTING: a large maternity hospital in Birmingham. PARTICIPANTS: all women who had delivered between April and September 1992, except for those who had had a neonatal death and, due to lack of funding for translators, Asian women. FINDINGS: the majority of women (91%) attended for their postnatal examination and 93% of these had an abdominal and 70% a vaginal examination. Women who had a vaginal delivery and perineal trauma were significantly more likely to have a vaginal examination but still over two-thirds of those with an intact perineum and almost half delivered by elective caesarean section also had this. Only 16% of women had a blood test. Those who had a PPH, a low third day Hb or reported a new postpartum onset of fatigue were more likely to have a blood test, but three-quarters of the women with these risk factors did not have blood taken. DISCUSSION AND CONCLUSION: women are prepared to attend for postnatal assessment but many have examinations without obvious reason, whilst other tests which might be helpful for certain conditions are infrequently used. Substantial postpartum morbidity is known to exist and this is not routinely assessed at the postnatal assessment. IMPLICATIONS FOR PRACTICE: the present six week postnatal examination does not appear to meet the health needs of women after childbirth: its content and timing should be reviewed.

What influences the uptake and early cessation of breast feeding?

OBJECTIVE: To examine obstetric, maternal and social factors associated with the uptake and early cessation of breast feeding and women's reasons for altering from breast to bottle feeding. DESIGN: Women who responded to a postal questionnaire on long-term postpartum health were contacted and asked to participate in a home-based interview. In addition to health problems, the interview obtained information on baby feeding and a number of social factors. Women were also asked to complete the Edinburgh Postnatal Depression Scale (EPDS). Obstetric and maternal data were obtained from maternity records. SETTING: Deliveries from a large maternity hospital in Birmingham. PARTICIPANTS: 906 women were interviewed at a mean of 45 weeks after delivery. FINDINGS: 63% of the women said they had breast fed, but 40% of these stopped within three months of delivery. Many of the women gave physical problems with lactation as reasons for stopping. The factors found to be predictors of early cessation were: return to work within three months of birth; regular childcare support from other female relatives, and a high EPDS score. Non-initiation of breast feeding was predicted by a different set of factors: multiparity; general anaesthetic (GA); and unmarried status. DISCUSSION AND CONCLUSION: Despite evidence of the benefits of breast feeding, this remains an unacceptable long-term option for many women, and for over one-third it is never attempted. Factors within the woman's social environment were found to influence early cessation. Women who had a GA during or immediately following labour and delivery were less likely to initiate breast feeding. IMPLICATIONS FOR PRACTICE: If breast-feeding incidence and duration are to increase, more attention should be paid to establishing early, successful breast feeding and countering the negative influences of factors within the social environment.

Faecal incontinence after childbirth.

OBJECTIVE: To measure the prevalence and severity of postpartum faecal incontinence, especially new incontinence, and to identify obstetric risk factors. DESIGN: A cohort study with information on symptoms collected in home-based interviews and obstetric data from hospital casenotes. SETTING: Deliveries from a maternity hospital in Birmingham. PARTICIPANTS: Nine hundred and six women interviewed a mean of 10 months after delivery. MAIN OUTCOME MEASURES: New faecal incontinence starting after the birth, including frank incontinence, soiling and urgency. RESULTS: Thirty-six women (4%) developed new faecal incontinence after the index birth, 22 of whom had unresolved symptoms. Twenty-seven had symptoms several times a week, yet only five consulted a doctor. Among vaginal deliveries, forceps and vacuum extraction were the only independent risk factors: 12 (33%) of those with new incontinence had an instrumental delivery compared with 114 (14%) of the 847 women who had never had faecal incontinence. Six of those with incontinence had an emergency caesarean section but none became incontinent after elective sections. CONCLUSIONS: Faecal incontinence as an immediate consequence of childbirth is more common than previously realised, and medical attention is rarely sought. Forceps and vacuum extraction deliveries are risk factors, with no protection demonstrated from emergency caesarean section. Identification and treatment is a priority.

Effects of redesigned community postnatal care on womens' health 4 months after birth: a cluster randomised controlled trial.

BACKGROUND: Much postpartum physical and psychological morbidity is not addressed by present care, which tends to focus on routine examinations. We undertook a cluster randomised controlled trial to assess community postnatal care that has been redesigned to identify and manage individual needs. METHODS: We randomly allocated 36 general practice clusters from the West Midlands health region of the UK to intervention (n=17) or control (19) care. Midwives from the practices recruited women and provided care. 1087 (53%) of 2064 women were in practices randomly assigned to the intervention group, with 977 (47%) women in practices assigned to the control group. Care was led by midwives, with no routine contact with general practitioners, and was extended to 3 months. Midwives used symptom checklists and the Edinburgh postnatal depression scale (EPDS) to identify health needs and guidelines for the management of these needs. Primary outcomes at 4 months were obtained by postal questionnaire and included the women's short form 36 physical (PCS) and mental (MCS) component summary scores and the EPDS. Secondary outcomes were women's views about care. Multilevel analysis accounted for possible cluster effects. FINDINGS: 801 (77%) of 1087 women in the intervention group and 702 (76%) of 977 controls responded at 4 months. Women's mental health measures were significantly better in the intervention group (MCS, 3.03 [95% CI 1.53-4.52]; EPDS -1.92 [-2.55 to -1.29]; EPDS 13+ odds ratio 0.57 [0.43-0.76]) than in controls, but the physical health score did not differ. INTERPRETATION: Redesign of care so that it is midwife-led, flexible, and tailored to needs, could help to improve women's mental health and reduce probable depression at 4 months' postpartum.
