Using the WHO individual near miss case review (NMCR) cycle to improve quality of emergency obstetric care and maternal outcome in Keren hospital, Eritrea: an interrupted time series analysis

Abstract

Abstract Background In 2016, the WHO regional office for Europe prepared a manual for conducting routine facility based individual near miss case review cycle. This study evaluates the effectiveness of the individual near miss case review (NMCR) cycle in improving quality of emergency obstetric care and maternal outcome in Keren hospital. Methods An interrupted time series design was used to achieve the objectives of this study. Monthly data on women with potentially life-threatening conditions (PLTCs) admitted between April 2018 and October 2022 (i.e. 33 months pre-implementation and 22 months post-implementation) were collected from medical records. Segmented regression analysis was used to assess the intervention’s effect on three process and outcome measures, namely, SMO, delayed care, and substandard care. The intervention was expected a priori to show immediate improvements without time-lag followed by gradual increment in slope. Segmented regression analyses were performed using the “itsa’ command in STATA. Results During the entire study period, 4365 women with potentially life threatening conditions were identified. There was a significant reduction in the post-implementation period in the proportion of mothers with PLTC who experienced SMO (− 8.86; p <  0.001), delayed care (− 8.76; p <  0.001) and substandard care (− 5.58; p <  0.001) compared to pre-implementation period. Results from the segmented regression analysis revealed that the percentage of women with SMO showed a significant 4.75% (95% CI: − 6.95 to − 2.54, p <  0.001) reduction in level followed by 0.28 percentage points monthly (95% CI: − 0.37 to − 0.14, p <  0.001) drop in trend. Similarly, a significant drop of 3.50% (95% CI: − 4.74 to − 2.26, p <  0.001) in the level of substandard care along with a significant decrease of 0.21 percentage points (95% CI: − 0.28 to − 0.14, p < 0.001) in the slope of the regression line was observed. The proportion of women who received delayed care also showed a significant 7% (95% CI: − 9.28 to − 4.68, p < 0.001) reduction in post-implementation level without significant change in slope. Conclusions Our findings suggest that the WHO individual NMCR cycle was associated with substantial improvements in quality of emergency obstetric care and maternal outcome. The intervention also bears a great potential for scaling-up following the guidance provided in the WHO NMCR manual.
