Abstract Background Hypertensive disorders in pregnancy is the second most common direct cause of maternal deaths accounting for 14% of maternal deaths worldwide. Severe pre-eclampsia and eclampsia are among the hypertensive disorders in pregnancy causing significant morbidity and mortality, hence categorized as Maternal Near Miss. At Muhimbili National Hospital these are the leading causes of maternal deaths accounting for 19.9% of maternal death. This study aimed to determine the proportion of severe maternal outcomes and maternal near-miss indices among patients with severe pre-eclampsia and eclampsia at Muhimbili National Hospital in Tanzania. Methods A descriptive cross-sectional study was conducted between September 2017 to January 2018 at Muhimbili National Hospital. Women with severe pre-eclampsia and eclampsia were recruited. Data were extracted from patient files after admission, and followed up until discharge or death; after discharge was categorized as maternal near miss or death as maternal death. The outcome indicators were calculated using the total number of live births during the study period, the number of maternal deaths and maternal near-miss due to severe pre-eclampsia/ eclampsia in the same period. Results Nearly two-thirds of women recruited, 199 (62.2%) had severe preeclampsia while 121 (37.8%) had eclampsia, 71 (22.1%) had severe maternal outcome whereby 63 had maternal near-miss with organ dysfunction and 8 maternal deaths. The overall maternal near-miss ratio was 87.4 while that for severe pre-eclampsia was 54, and 33 per 1000 live births for eclampsia. Overall severe maternal outcome ratio was 19.4 while that for severe pre-eclampsia was 12 and that for eclampsia was 9.5 per 1000 live births. Mortality index was 11% and the Case fatality rate was 2.5%. Conclusion There is a high proportion of women with severe maternal outcome attributable to severe pre-eclampsia and eclampsia, with a reduced proportion of maternal deaths. This signifies improvement of performance in our facility in dealing with patients with severe morbidities due to severe pre-eclampsia and eclampsia, however, more effort should be put to further reduce maternal mortality.
