To study the impact of COVID-19 pandemic on maternal mortality ratio, aetiological and modifiable factors for maternal mortality and key interventions performed. Retrospective exploratory study evaluating maternal mortality between April to November 2020 (study group) and 2019 (control group). Demographic variations existed in the two groups. Increased maternal age and illiteracy were significantly more in the study group. Maternal mortality ratio (MMR) was significantly high in the study group (792 vs. 296 p value = 0.0). Hemorrhage accounted for 20% and COVID-19-related maternal deaths accounted for 15% deaths in the study group. Level 3 delay (delay in receiving care/inadequate care) was observed in 35% in the study group and 28% in control group (p value = 0.349). 17.5% of mothers in the study group as compared to 8% of control group were dead on arrival to hospital though not statistically significant (p value = 0.28). Significantly more women in study group died within 24 h of admission (45% vs. 20%, p value 0.04). Among the key interventions, the use of supplemental oxygen was significantly high in study group (p value = 0.02). Maternal mortality ratio was high in the pandemic year because of a significant decline in hospital delivery rate. The lesson learnt from this pandemic needs to be documented to guide better planning in the future to face similar situations.
