    Abstract:
    BACKGROUND: A study in Matlab, Bangladesh, has provided evidence favouring a community-based maternity-care delivery system. 3 years of this programme coincided with a significant reduction in direct obstetric mortality compared with the 3 years before the programme. We have examined whether the effects of the programme are sustained over time. METHODS: Using data from the continuing demographic survelliance system and from special investigations into the rates and causes of maternal mortality during 1976-93, we compared the trends in direct obstetric maternal mortality ratios in the Maternal and Child Health and Family Planning (MCH-FP) area (which has received extensive services in health and family planning since 1977) with those in the comparison area (with no such intensive health inputs). We divided the areas and time periods into discrete groups that best represented the effects of the introduction of the maternity-care programme. FINDINGS: Direct obstetric mortality declined by 3% per year (rate ratio 0.97 per year [95% CI 0.95-0.99]); there was no difference between the MCH-FP and comparison areas (1.00 [0.96-1.05]). Direct obstetric mortality halved between 1976-86 and 1987-89 in the northern MCH-FP area, where the maternity-care programme was initiated in 1987 (0.50 [0.22-0.99]), but showed no change in the southern MCH-FP area, which had no such intervention at that time (1.07 [0.64-1.72]). After 1990, when the programme was expanded throughout the MCH-FP area, the southern part showed a downward (non-significant) trend in direct obstetric mortality (0.68 [0.35-1.32]). However, direct obstetric mortality also declined between 1987 and 1989 in the southern comparison area (0.48 [0.26-0.83]) in the absence of an intense maternity-care programme, and remained stable thereafter. In the northern comparison area, there was no such decline in direct obstetric mortality (0.78 [0.40-1.40]). INTERPRETATION: Although the introduction of the maternity-care programme coincided with declining trends in direct obstetric mortality in the areas covered by the programme, a decline also occurred in one of the areas not receiving any such interventions. Caution is required in the interpretation of short-term trends in one indicator in studies designed without random allocation of interventions into treatment and control groups. This study examines the impact of the Maternal-Child Health and Family Planning (MCH-FP) program in the Matlab, Bangladesh. Data were obtained from the Matlab surveillance system for treatment and comparison areas. This study reports the trends in maternal mortality since 1976. The MCH-FP area received extensive services in health and family planning since 1977. Services included trained traditional birth attendants and essential obstetric care from government district hospitals and a large number of private clinics. Geographic ease of access to essential obstetric care varied across the study area. Access was most difficult in the northern sector of the MCH-FP area. Contraception was made available through family welfare centers. Tetanus immunization was introduced in 1979. Door-to-door contraceptive services were provided by 80 female community health workers on a twice-monthly basis. In 1987, a community-based maternity care program was added to existing MCH-FP services in the northern treatment area. The demographic surveillance system began collecting data in 1966. During 1976-93 there were 624 maternal deaths among women aged 15-44 years in Matlab (510/100,000 live births). 72.8% of deaths were due to direct obstetric causes: postpartum hemorrhage, induced abortion, eclampsia, dystocia, and postpartum sepsis. Maternal mortality declined in a fluctuating fashion in both treatment and comparison areas. Direct obstetric mortality declined at about 3% per year. After 1987, direct obstetric mortality declined in the north by almost 50%. After the 1990 program expansion in the south, maternal mortality declined, though not significantly, in the south. Maternal mortality declined in the south comparison area during 1987-89 and stabilized. The comparison area of the north showed no decline.
