This thesis assesses some indicators of quality for maternity care in Tanzania, using antenatal management of anaemia and hypertension and emergency obstetric care as focal points. The care of pregnant women consecutively enrolled in antenatal care (n=379) was observed and compared with quality standard criteria. From a tertiary level labour ward 741 cases of eclampsia were identified and their antenatal care analyzed. A health systems analysis was performed for 205 cases of pregnancy complications at district level.,There was inadequate equipment and drugs, inadequate staff knowledge and motivation, and incorrect measurements for investigating anaemia and hypertension in pregnancy. Hospital incidence of eclampsia at tertiary level was 200/10,000 live births, and was not modified by antenatal care. The quality observed in the antenatal programme indicated little impact on either anaemia or hypertensive complications. Compliance with obstetric referral was only 46% and all four observed maternal deaths occurred due to transport problems. The proposed process indicators for essential obstetric care were inadequate to assess the quality of care on a district level. There is a need to address structural weaknesses, to motivate health workers and to improve training on quality improvement. More research is warranted on indicators for obstetric needs, accessibility and referral system.
