Perinatal and maternal mortality in a religious group avoiding obstetric care

The impact of maternal health improvement on perinatal survival: cost-effective alternatives

Each year, an estimated half million women die from complications related to child birth either during pregnancy, delivery or within 42 days afterwards. When pregnant women have complications, their infants are at greater risk of becoming ill, permanently disabled or dying. For every maternal death, there are at least 20 infant deaths: stillbirths, neonatal or postneonatal deaths. Altogether, an estimated 7 million infants each year die perinatally (stillborn or deaths within the first week of life). Low cost, feasible, and effective intervention strategies include: a) improved family planning and abortion services; b) obstetric care at delivery; and, c) prenatal services. Two hypothetical populations of one million (a low mortality and a high mortality country) are used to illustrate maternal and perinatal program strategies and priorities. In countries with high fertility, major reductions in maternal and infant deaths result both from reductions in the number of pregnancies through family planning and from improved obstetric care. Where fertility is already low, reductions result almost entirely from improved obstetric and prenatal care. The investments required are relatively low, while the potential gains are great. The cost to avert each death in a high mortality population is estimated between $800 and $1,500 or as low as $0.50 per capita per year. The priorities for programs targeting maternal and perinatal health depend on demographic, ecologic and economic factors, and should include the promotion of good health, not merely the avoidance of death. More operational research is required on various aspects of maternal and perinatal health; in particular, on the cost-effectiveness of different service components.

Poor antenatal care and pregnancy outcome

OBJECTIVES

To characterize women receiving poor antenatal care and assess their perinatal risk.

DESIGN

Computerized data.

SETTING

Public hospital setting Paris (1987-1990). Comparison with representative sample in Ile-de-France region (n = 6423).

METHODS

Poor attenders with less than 3 visits (n = 210) were compared with good attenders with 3 visits or more (n = 5631).

RESULTS

Poor attenders were younger and had higher rates of perinatal mortality (4.7%), preterm delivery (Odds ratio 5.2:4.3-6.3) and low birth weight (Odds ratio 4.6:3.7-5.6).

CONCLUSION

Women with poor antenatal care have a greater risk for adverse pregnancy outcome. This risk cannot be attributed to unfavourable living conditions only.

Born before arrival--uncovering the hazards

In a retrospective case controlled study the demographic background and outcome of 193 mothers whose babies were born before arrival at hospital was compared to that of a control group who delivered within the maternity units of 2 teaching hospitals in Hong Kong. Mothers who delivered before arrival at hospital were significantly more likely to be single, to have received no antenatal care, to have an unplanned pregnancy, low family income and to come from a socially disadvantaged group such as Vietnamese refugees and illegal immigrants from China. Lacerations to the genital tract, postnatal anaemia and blood transfusions were more common in the study group. Results of cervical cytology and rubella status were available in significantly fewer of these mothers. They were more likely to be ambivalent about contraception and less likely to attend the postnatal clinic. The perinatal mortality and morbidity was significantly increased.

Maternal mortality in Hong Kong 1961-1985

The maternal mortality rate in Hong Kong fell from 0.45/1000 total births in 1961 to 0.05/1000 total births in 1985. During the period between 1961 and 1985 there were a total of 438 maternal deaths and 2,193,012 births. Of the 438 deaths 150 (34%) were due to haemorrhage during pregnancy and childbirth (ICD 640, 641, 666), 89 (20%) were due to pre-eclampsia (ICD 642, 643) and 60 (13.7%) were due to ectopic pregnancy (ICD 633). Comparison of maternal deaths by cause between the periods 1961-1965 and 1981-1985 showed an 86% reduction in deaths due to haemorrhage and pre-eclampsia and a 72% reduction in deaths due to ectopic pregnancy. Pulmonary embolism was not a major cause of maternal mortality.

The impact of early medical technology on maternal mortality in late 19th century Sweden

The prevention of fatal complications of childbirth is a priority of health care in the developing countries. This historical study of maternal deaths in Sweden analyses the decline in mortality between 1751-1900 and during this years maternal mortality was reduced by 76% whereas the female mortality dropped only by 33% The decline was especially pronounced during the period 1861-1900, when maternal mortality declined from 567 to 227 per 100,000 live births. The potential impact of medical technology was analysed by epidemiological methods for the period 1861-1900. The introduction of antiseptic technique was estimated to reduce septic maternal mortality 25-fold in lying-in hospitals and 2.7-fold in rural home deliveries, implying that 49% of the septic maternal deaths were thus "prevented". In addition, licensed midwives assisting at home deliveries were estimated to reduce non-septic mortality 5-fold, thus "preventing" 46% of the non-septic maternal deaths. This could be one explanation why Sweden had a lower maternal mortality than the U.S. and the U.K. in the beginning of the 20th century.

The perinatal and economic impact of prenatal care in a low-socioeconomic population

Reductions in publicly funded prenatal care programs in 1981 to 1984 resulted in an increase in unregistered patient deliveries from 7.8% to 14.9% of births at University of California San Diego Medical Center. To assess the economic and perinatal impact of the increasing number of deliveries of women without prenatal care, 100 consecutive patients with fewer than three prenatal visits were studied. Each "no care" patient was matched by age, parity, and week of delivery with a control patient who received care in a state-funded perinatal project (Comprehensive Perinatal Program). Maternal antenatal risk factors were equally distributed between the two groups when maternal age, parity, history of substance abuse, prior preterm delivery, hypertension, and abortion were compared. Maternal obstetric outcomes were similar, including cesarean section rate and incidence of postpartum fever and hemorrhage. However, neonates delivered of women receiving no care experienced significantly greater morbidity than the neonates of women in the Comprehensive Perinatal Program, including an increased incidence of premature rupture of the membranes and preterm delivery (13% versus 2%, p less than 0.05), low birth weight (21% versus 6% less than 2500 gm, p less than 0.002), and intensive care unit admissions (24% versus 10%, p less than 0.005). When the total inpatient hospital charges were tabulated for each mother-baby pair, the cost of perinatal care for the group receiving no care ($5168 per pair) was significantly higher than the cost for patients in the Comprehensive Perinatal Program ($2974 per pair, p less than 0.001) including an antenatal charge of $600 in the Comprehensive Perinatal Program. The excess cost for delivery of 400 women receiving no care per year in the study hospital was $877,600. These results suggest that extension of prenatal care programs to medically indigent women is likely to result in a net reduction in perinatal morbidity and health care expenditures.
