How effective is antenatal care in preventing maternal mortality and serious morbidity? An overview of the evidence

Avaliação da implantação de programa de atenção pré-natal no Município de Curitiba, Paraná, Brasil: estudo em coorte de primigestas

A assistência pré-natal tem sido alvo de avaliações acerca dos seus componentes essenciais e impactos em contextos diversos. Em 1999, um novo programa de atenção pré-natal para as mulheres usuárias do SUS passou a vigorar no Município de Curitiba, Paraná, Brasil, com modificações no fluxo de atendimento, número e distribuição de consultas, e procedimentos necessários a cada consulta, criando a oportunidade de realizar uma pesquisa com o objetivo de avaliar a sua implantação efetiva, tomando por referência as diretrizes técnicas estabelecidas pelo programa. O estudo abrangeu uma coorte de 660 primigestas, inscritas antes da vigésima semana de gravidez, entre março e agosto de 2000, com informações obtidas por meio de duas entrevistas domiciliares, consulta no cartão da gestante ou prontuário ambulatorial, e no prontuário hospitalar. A disponibilidade, acessibilidade e seguimento do protocolo pelos profissionais demonstram-se satisfatórias, mas mantém-se um início tardio e distribuição inadequada das consultas. Na classificação de adequação geral adotada, apenas 38,6% das mulheres preencheram todos os requisitos. Os resultados contribuem para a compreensão das complexas determinações presentes no desempenho adequado de um programa de pré-natal.

The International Confederation of Midwives' study of essential competencies of midwifery practice

OBJECTIVE

To delineate the knowledge, skills, and behaviours that would characterise the domain of competencies of the midwife who is educated according to the international definition of the profession.

DESIGN

Phase I: a qualitative Delphi study; Phase II: a descriptive survey research process.

PARTICIPANTS

A stratified random sample of member organisations of the International Confederation of Midwives (ICM) and regulatory representatives from these same countries.

FINDINGS

A list of basic (essential) and additional competencies for midwives who have been educated in keeping with the ICM/WHO/FIGO international definition of the midwife was developed through an interative Delphi process, and then affirmed, using a survey research method. The final list includes 214 individual task statements within six domains of midwifery practice.

IMPLICATIONS FOR PRACTICE

This list of competencies can serve as a basis for educational curriculum design, as a guideline for regulatory policy development, as a reference document for individual practitioners in an assessment of their initial and continued competency and by the ICM and its member associations as a resource for advocating for the role of midwifery within health-care systems world-wide.

A framework for a new approach to antenatal care

A framework for a new approach to antenatal care (ANC) is presented to improve maternal health. Based on evaluations of ANC, safe motherhood programs, gender and social theory, it suggests that managers should draw upon existing family and community support systems, and develop partnerships beyond the health service. Policy and program changes are required in: professional mandates for ANC providers, organization of ANC services, service protocols, training programs, policy towards TBAs, referral care, and service support systems.

Anemia in pregnancy in rural Tanzania: associations with micronutrients status and infections

OBJECTIVE

We studied the association between anemia in pregnancy and characteristics related to nutrition and infections.

DESIGN

Cross-sectional study.

SETTING

Four antenatal clinics in rural northern Tanzania.

SUBJECTS/METHODS

A total of 2547 women were screened for hemoglobin (Hb) and malaria plasmodia in capillary blood and for infections in urine. According to their Hb, they were assigned to one of five groups and selected accordingly, Hb<70 g/l (n=10), Hb=70-89 g/l (n=61), Hb=90-109 g/l (n=86), Hb=110-149 g/l (n=105) and Hb> or =150 g/l (n=50). The 312 selected subjects had venous blood drawn, were interviewed, and their arm circumference was measured. The sera were analyzed for ferritin, iron, total iron binding capacity (TIBC), cobalamin, folate, vitamin A, C-reactive protein (CRP), and lactate dehydrogenase (LD). Transferrin saturation (TFsat) was calculated. Urine was examined by dipsticks for nitrite.

MAIN OUTCOME MEASURES

Unadjusted and adjusted odds ratio (OR and AOR) of anemia with Hb<90 g/l.

RESULTS

Anemia (Hb<90 g/l) was associated with iron deficiency (low s-ferritin; AOR 3.4). The association with vitamin deficiencies were significant in unadjusted analysis (low s-folate; OR 3.1, low s-vitamin A; OR 2.6). Anemia was also associated with markers of infections (elevated s-CRP; AOR 3.5, urine nitrite positive; AOR 2.4) and hemolysis (elevated s-LD; AOR 10.1). A malaria positive blood slide was associated with anemia in unadjusted analysis (OR 2.7). An arm circumference less than 25 cm was associated with anemia (AOR 4.0). The associations with less severe anemia (Hb 90-109 g/l) were similar, but weaker.

CONCLUSIONS

Anemia in pregnancy was associated with markers of infections and nutritional deficiencies. This should be taken into account in the management of anemia at antenatal clinics.

SPONSORSHIP

The study was supported by the Norwegian Research Council (NFR) and the Centre for International Health, University of Bergen.

The gap between evidence and practice in maternal healthcare

The expected improvement in maternal and perinatal health in developing countries has not yet materialized. In addition to the factors related to socioeconomic conditions, we have identified areas where large gaps between evidence and practice are apparent. These gaps are in clinical care, implementation of effective practices and in selecting research priorities. We present examples from our own research and the literature to illustrate these points.
