Assessment of quality of obstetric care in Zimbabwe using the standard primipara

Background To improve maternity services in any country, there is need to monitor the quality of obstetric care. There is usually disparity of obstetric care and outcomes in most countries among women giving birth in different obstetric units. However, comparing the quality of obstetric care is difficult because of heterogeneous population characteristics and the difference in prevalence of complications. The concept of the standard primipara was introduced as a tool to control for these various confounding factors. This concept was used to compare the quality of obstetric care among districts in different geographical locations in Zimbabwe. Methods This was a substudy of the Zimbabwe Maternal and Perinatal Mortality Study. In the main study, cluster sampling was done with the provinces as clusters and 11 districts were randomly selected with one from each of the nine provinces and two from the largest province. This database was used to identify the standard primipara defined as; a woman in her first pregnancy without any known complications who has spontaneous onset of labour at term. Obstetric process and outcome indicators of the standard primipara were then used to compare the quality of care between rural and urban, across rural and across urban districts of Zimbabwe. Results A total of 45,240 births were recruited in the main study and 10,947 women met the definition of standard primipara. The maternal mortality ratio (MMR) and the perinatal mortality rate (PNMR) for the standard primiparae were 92/100000 live births and 15.4/1000 total births respectively. Compared to urban districts, the PNMR was higher in the rural districts (11/1000 total births vs 19/ 1000 total births, p < 0.001). In the urban to urban and rural to rural districts comparison, there were significant differences in most of the process indicators, but not in the PNMR. Conclusions The study has shown that the standard primipara can be used as a tool to measure and compare the quality of obstetric care in districts in different geographical areas. There is need to explore further how the quality of obstetric care can be improved in rural districts of Zimbabwe

Prepregnancy and early pregnancy calcium supplementation among women at high risk of pre-eclampsia : a multicentre, double-blind, randomised, placebo-controlled trial

CITATION: Hofmeyr, G. J., et al. 2019. Prepregnancy and early pregnancy calcium supplementation among women at high risk of pre-eclampsia : a multicentre, double-blind, randomised, placebo-controlled trial. The Lancet, 393(10169):P330-339, doi:10.1016/S0140-6736(18)31818-X.The original publication is available at https://www.thelancet.comBackground: Reducing deaths from hypertensive disorders of pregnancy is a global priority. Low dietary calcium might account for the high prevalence of pre-eclampsia and eclampsia in low-income countries. Calcium supplementation in the second half of pregnancy is known to reduce the serious consequences of pre-eclampsia; however, the effect of calcium supplementation during placentation is not known. We aimed to test the hypothesis that calcium supplementation before and in early pregnancy (up to 20 weeks’ gestation) prevents the development of pre-eclampsia Methods: We did a multicountry, parallel arm, double-blind, randomised, placebo-controlled trial in South Africa, Zimbabwe, and Argentina. Participants with previous pre-eclampsia and eclampsia received 500 mg calcium or placebo daily from enrolment prepregnancy until 20 weeks’ gestation. Participants were parous women whose most recent pregnancy had been complicated by pre-eclampsia or eclampsia and who were intending to become pregnant. All participants received unblinded calcium 1·5 g daily after 20 weeks’ gestation. The allocation sequence (1:1 ratio) used computer-generated random numbers in balanced blocks of variable size. The primary outcome was pre-eclampsia, defined as gestational hypertension and proteinuria. The trial is registered with the Pan-African Clinical Trials Registry, number PACTR201105000267371. The trial closed on Oct 31, 2017. Findings: Between July 12, 2011, and Sept 8, 2016, we randomly allocated 1355 women to receive calcium or placebo; 331 of 678 participants in the calcium group versus 320 of 677 in the placebo group became pregnant, and 298 of 678 versus 283 of 677 had pregnancies beyond 20 weeks’ gestation. Pre-eclampsia occurred in 69 (23%) of 296 participants in the calcium group versus 82 (29%) of 283 participants in the placebo group with pregnancies beyond 20 weeks’ gestation (risk ratio [RR] 0·80, 95% CI 0·61–1·06; p=0·121). For participants with compliance of more than 80% from the last visit before pregnancy to 20 weeks’ gestation, the pre-eclampsia risk was 30 (21%) of 144 versus 47 (32%) of 149 (RR 0·66, CI 0·44–0·98; p=0·037). There were no serious adverse effects of calcium reported. Interpretation: Calcium supplementation that commenced before pregnancy until 20 weeks’ gestation, compared with placebo, did not show a significant reduction in recurrent pre-eclampsia. As the trial was powered to detect a large effect size, we cannot rule out a small to moderate effect of this intervention. ernal and Child Health.https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(18)31818-X/fulltextPublisher's versio

Incidence of maternal near miss in the public health sector of Harare, Zimbabwe: a prospective descriptive study

Abstract Background Maternal ‘near miss’ can be a proxy for maternal death and it describes women who nearly died due to obstetric complications. It measures life threatening pregnancy related complications and allows the assessment of the quality of obstetric care. Methods A prospective descriptive study was carried out from October 1 2016 to 31 December 2016, using the WHO criteria for maternal ‘near miss’ at the two tertiary public hospitals which receive referrals of all obstetric complications in Harare city, Zimbabwe. The objective was to calculate the ratio of maternal ‘near miss’ and associated factors. All pregnant women who developed life threatening complications classified as maternal near miss using the WHO criteria were recruited and followed up for six weeks from discharge, delivery or termination of pregnancy or up to the time of death. Results During this period there were 11,871 births. One hundred and twenty three (123) women developed severe maternal outcomes, 110 were maternal ‘near miss’ morbidity and 13 were maternal deaths. The maternal ‘near miss’ ratio was 9.3 per 1000 deliveries, the mortality index (MI) was 10.6% and the maternal mortality ratio was 110 per 100,000 deliveries. The major organ dysfunction among cases with severe maternal outcomes (SMO) was cardiovascular dysfunction (76.9%). The major causes of maternal near miss were obstetric haemorrhage (31.8%), hypertensive disorders (28.2%) and complications of miscarriages (20%). The intensive care unit (ICU) admission rate was 7.3 per 100 cases of SMO and 88.8% of maternal deaths occurred without ICU admission. Conclusion The MNM ratio was comparable to that in the region. Obstetric haemorrhage was a leading cause of severe maternal morbidity though with less mortality when compared to hypertensive disorders and abortion complications. Zimbabwe should adopt maternal near miss ratio as an indicator for evaluating its maternal health services
