AIM: To compare perinatal morbidity and mortality for babies delivered in water with rates for babies delivered conventionally (not in water). DESIGN: Surveillance study (of all consultant paediatricians) and postal survey (of all NHS maternity units). SETTING: British Isles (surveillance study); England and Wales (postal survey). SUBJECTS: Babies born in the British Isles between April 1994 and March 1996 who died perinatally or were admitted for special care within 48 hours of birth after delivery in water or after labour in water followed by conventional delivery (surveillance study); babies delivered in water in England and Wales in the same period (postal survey). MAIN OUTCOME MEASURESE Number of deliveries in water in the British Isles that resulted in perinatal death or in admission to special care within 48 hours of birth; and proportions (of such deliveries) of all water births in England and Wales. RESULTS: 4032 deliveries (0.6% of all deliveries) in England and Wales occurred in water. Perinatal mortality was 1.2/1000 (95% confidence interval 0.4 to 2.9) live births; 8.4/1000 (5.8 to 11.8) live births were admitted for special care. No deaths were directly attributable to delivery in water, but 2 admissions were for water aspiration. UK reports of mortality and special care admission rates for babies of women considered to be at low risk of complications during delivery who delivered conventionally ranged from 0.8/1000 (0. 2 to 4.2) to 4.6/1000 (0.1 to 25) live births and from 9.2 (1.1 to 33) to 64/1000 (58 to 70) live births respectively. Compared with regional data for low risk, spontaneous, normal vaginal deliveries at term, the relative risk for perinatal mortality associated with delivery in water was 0.9 (99% confidence interval 0.2 to 3.6). CONCLUSIONS: Perinatal mortality is not substantially higher among babies delivered in water than among those born to low risk women who delivered conventionally. The data are compatible with a small increase or decrease in perinatal mortality for babies delivered in water.
OBJECTIVES: To determine if the Advisory Committee on Immunization Practices hepatitis B screening, vaccination, and prophylaxis recommendations were being followed in North Carolina, and to establish a baseline hepatitis B seroprevalence rate. DESIGN: A survey of mother and infant birthing facility medical records. SETTING: Four birthing facilities selected from each of the 7 districts in North Carolina (a total of 28 facilities). PARTICIPANTS: A probability proportional to size survey design was used to select 4763 mother-infant record pairs. All records came from the 1996 birth cohort. MAIN OUTCOME MEASURES: Maternal hepatitis B screening status, infant vaccination status, infants prophylaxis status, hepatitis B seroprevalence rate, demographic and clinical predictors for maternal infection, failure to receive prenatal care or for whom status was unknown, failure to screen, and failure to vaccinate. RESULTS: Ninety-two percent of pregnant women were screened for hepatitis B surface antigen. Eighty-six percent of infants received dose 1 of the hepatitis B vaccine. Four of the 9 infants with mothers who were hepatitis B surface antigen-positive did not receive both vaccine and hepatitis B immune globulin. The hepatitis B seroprevalence rate was 0.2%. Mothers who were not screened for infection were 3.4 times more likely to have infants who were not vaccinated. White mothers were twice as likely not to have their child vaccinated as mothers of other races. CONCLUSIONS: Not all infants with hepatitis B-infected mothers were receiving vaccine and hepatitis B immune globulin as recommended. Seroprevalence of hepatitis B infection may be lower in North Carolina than in other states. Hepatitis B laboratory test results should be included in every mother's medical record.
OBJECTIVE: Our purpose was to compare birth complications and fetal outcome in hospitals and birth centers. METHOD: We retrospectively compared all 801 deliveries between 1992 and 1994 from two free-standing birth centers against 3271 hospital deliveries in Berlin. The hospital collective was selected according to the same risk criteria of the birth centers. RESULTS: The birth center group had significantly fewer medical interventions, with a similar cesarean section rate (3.0% vs. 4.6%, P = 0.057) and occurrence of severe perineal lesions. The episiotomy rate was significantly higher (P < 0.001) in the clinics for first-time and multiple births. The perinatal mortality was not significantly different ( < 0.1 per 1000). One-minute Apgar scores less than 7 were found significantly more often in the birth center group. CONCLUSION: When birth centers employ thorough risk selection and significant early referral rates to nearby hospitals, there is no evidence of increased maternal or perinatal risk compared to hospital deliveries.
