Comparison of Causes of Maternal Near Miss and Maternal Mortality in a Tertiary Care Hospital: A Prospective Study

The Maternal Near miss (MNM) concept has led to a more comprehensive and better assessment of the effect of care on maternal health. Investigating severe life-threatening pregnancy complications that women encounter and maternal morbidities (near misses) may help evaluate the quality of care in health facilities and recommend ways to improve maternal survival, especially in poor resource settings. Aim This study aimed to identify causes, classify, and determine the nature of complications in maternal near misses and in maternal death. Material and Methods The hospital-based prospective cohort study was conducted in the Department of Obstetrics and Gynecology, Jawaharlal Nehru Medical College, Aligarh Muslim University of Aligarh from 2020 to 2022. The study was approved by the Institutional Ethics Committee and informed written consent was obtained from the study participants. The outcome measures included causes, organ dysfunction, complications, maternal morbidities, and neonatal outcome. Results: Higher rate of unbooked referrals was observed in our study. Hemorrhage was 42.9%, followed by 39.1% hypertensive disorders, 8.6% sepsis in the maternal near miss group while in the maternal mortality group, 26.1% had hypertensive disorders followed by 23.8% women had hemorrhagic disorders, and 20.4% had sepsis. There was a significant difference in HDU, ICU Hospital stay and IUDs in the maternal mortality group compared to the maternal near-miss group. Conclusion The WHO near-miss approach was found to represent a feasible strategy in low-resource settings each Near Miss should be evaluated in detail to diagnose underlying pathology, correct and timely detection of complications, prompt referral and early institution of essential and comprehensive obstetrics care are important for maternal and infant survival.

Low Incidence of Maternal Near-Miss in Zhejiang, a Developed Chinese Province: A Cross-Sectional Study Using the WHO Approach.

Background and AimMaternal near-miss (MNM) surveillance has been developed to identify severe complications in pregnancy since 2011 in China. However, very little is known about MNM in China. This study aims to explore the prevalence of MNM, the risk factors, and perinatal outcomes using the WHO near-miss approach in a developed Chinese province.Materials and MethodsWe used data from China’s National Maternity Near Miss Obstetrics Surveillance System for the period 2012 to 2017, which included 18 hospitals in Zhejiang Province. Chi-squared tests were used to compare the socio-demographic factors, obstetric complications and perinatal outcomes between women with and without MNM. Logistic regression was used to examine the independent risk factors for MNM.ResultsA total of 612,264 pregnant women were recruited. There were 3208 MNM cases and 34 maternal deaths. The MNM incidence ratio was low at 5.9 per 1,000 live births, with an MNM mortality ratio of 98:1 and mortality index of 1.1%. Among 3208 women with MNM, postpartum hemorrhage was the commonest cause at 76.3% followed by severe anemia at 23.7% and placenta previa at 23.0%. Embolism was identified as having the highest risk for MNM (AOR 46.0; 95% CI 19.1–110.7), followed by postpartum hemorrhage (AOR 41.0; 95% CI 35.7–47.0), and severe anemia (AOR 36.6; 95% CI 16.0–84.1). MNM cases were significantly associated with severe perinatal outcome, including premature birth, low birth weight, multiple fetuses, stillbirth rates and neonatal mortality.ConclusionOverall near-miss indicators suggested a relatively high quality of maternal health care in a developed province of China. The identified risk factors may be helpful in developing targeted interventions for improving maternal safety.

Retrospective analysis of patients with severe maternal morbidity receiving anaesthesia services using 'WHO near miss approach' and the applicability of maternal severity score as a predictor of maternal outcome.

Background and Aims:Risk stratification of severely morbid obstetric patients receiving anaesthesia services can be helpful in improving maternal outcomes. This study was undertaken to analyse these patients using the WHO near-miss (NM) approach and to assess the applicability of maternal severity score (MSS) to predict maternal mortality.Methodology:This is a one-year retrospective cohort analysis at a tertiary care centre. Of all the obstetric patients receiving anaesthesia, those with 'potentially life-threatening conditions' (PLTC) were identified. Amongst women with PLTC, those fulfilling the WHO NM criteria were grouped into either maternal near miss (MNM) or maternal death (MD) depending on final survival outcome. The MSS was assessed upon admission to post-anaesthesia ICU. The cases of “near miss” were compared to maternal death to determine the factors and WHO NM criteria significantly associated with mortality. Area under ROC curve (AUROC) was used to assess the accuracy of MSS to predict maternal mortality.Results:Of the 4351 anaesthetised obstetric patients, 301 were PLTC, 59 MNM and 11 MD. Obstetric haemorrhage was the commonest PLTC with the highest risk for MNM and MD. Preoperative organ dysfunction, referral from other centres, intra-uterine fetal death (IUFD) and WHO cardiovascular and respiratory NM criteria were significantly associated with mortality. MSS had excellent accuracy for the prediction of mortality (AUROC was 0.986 and 95% CI 0.966–0.996).Conclusion:Haemorrhage is the leading cause of MNM and MD. MSS is reliable in stratifying the severity of maternal morbidity and in predicting maternal mortality. Thus it can be used as an effective prognostic tool.

Using Near Miss Model to Evaluate the Quality of Maternal Care at a Tertiary Health-Care Center: A Prospective Observational Study.

Near miss (NM) concept has led to a more comprehensive and better assessment of effect of care on maternal health. It indicates the degree of organ function failure in the wide spectrum of severity. This was a prospective observational study conducted from July 2015 to Feb 2016. Among women with potentially life-threatening conditions (PLTCs), those fulfilling one or more WHO NM criteria were included and followed up till the final outcome (NM or death). Various critical interventions done in them were associated with the final outcome. Standardized mortality ratio (SMR) was calculated for assessment of overall quality of health care provided. One thousand seven hundred and thirty-nine patients had PLTCs of which 174 (10%) patients were identified as NM. Of 174 patients, 116 patients (66.66%) were discharged in stable condition (group A) and 58 patients (33.34%) died (group B). Hemorrhage (31.8%) was the most frequent complication in group A followed by hypertensive disorders (18.1%) and severe anemia (11.2%). The two most common causes of maternal mortality were hypertensive disorders (27.6%) and hemorrhage (24.1%). Only two critical interventions (assisted ventilation and massive blood transfusion) had significant association with the final outcome. SMR of our center was 1.187 indicating adequate quality of provision of care to the patients. Hemorrhage and hypertensive disorders were the two most common causes of NM and deaths highlighting the importance of their prompt diagnosis and vigorous management. Periodic SMR calculation can be used as an audit to guide us in improving the overall status of maternal health.

Validity of WHO's near-miss approach in a high maternal mortality setting.

ObjectiveTo evaluate the validity of WHO’s near-miss approach in a low-resource, high maternal mortality setting.DesignProspective cohort study.SettingMnazi Mmoja Hospital, the main referral hospital of Zanzibar, Tanzania, from 1 April 2017 until 31 December 2018.PopulationAll women, pregnant or until 42 days after the end of pregnancy, admitted at Mnazi Mmoja Hospital, the tertiary referral hospital in Zanzibar.MethodsCases of maternal morbidity and mortality were evaluated according to WHO’s near-miss approach. The approach’s performance was determined by calculating its accuracy through sensitivity, specificity and positive and negative likelihood ratios. The approach’s validity was assessed with Pearson’s correlation coefficient between the number of organ dysfunction markers and risk of mortality.Main outcomes measuresCorrelation between number of organ dysfunction markers and risk of mortality, sensitivity and specificity.Results26,842 women were included. There were 335 with a severe maternal outcome: 256 maternal near-miss cases and 79 maternal deaths. No signs of organ dysfunction were documented in only 4 of the 79 cases of maternal death. The number of organ dysfunction markers was highly correlated to the risk of mortality with Pearson’s correlation coefficient of 0.89.ConclusionsWHO’s near-miss approach adequately identifies women at high risk of maternal mortality in Zanzibar’s referral hospital. There is a strong correlation between the number of markers of organ dysfunction and mortality risk.

Applicability of WHO Maternal Severity Score (MSS) and Maternal Severity Index (MSI) Model to predict the maternal outcome in near miss obstetric patients: a prospective observational study.

To assess the applicability of WHO Maternal Severity Score (MSS) and Maternal Severity Index (MSI) Model in near miss (NM) obstetric patients METHODS: It was a prospective observational study conducted at a tertiary health care center from July 2015 to Feb 2016. All patients fulfilling one or more WHO NM criteria were included. MSS and MSI were calculated for all NM patients on admission. They were then followed up till the final outcome (NM or death). Each NM parameter, system-wise MSS, total MSS and MSI were then associated with the final outcome. Of 4822 patients, 1739 had potentially life-threatening conditions of which 174 were identified as NM. The average MSS and MSI of patients who remained NM was 4.41 and 11.67%, respectively, and those who died was 9.47 and 58.16%, respectively. Both were found to be significantly associated with the outcome (p < 0.001). MSI had good accuracy for maternal death prediction in women with markers of organ dysfunction (AUROC - 0.838 [95% CI 0.766-0.910]). However, of 25 NM criteria, only 17 NM criteria and 3 system dysfunctions (cardiovascular, respiratory and neurological) were found to associate significantly with the outcome. MSS and MSI act as good prognostic tools to assess the severity of maternal complications and estimate the probability of death in NM patients. As all NM parameters are not equally predictive of severity of maternal morbidity, different scores per NM parameter and system should be assigned while calculating MSS for better prognostication.

Severe maternal morbidity in Zanzibar's referral hospital: Measuring the impact of in-hospital care.

Objectiveto analyse the impact of in-hospital care on severe maternal morbidity using WHO’s near-miss approach in the low-resource, high mortality setting of Zanzibar’s referral hospital.SettingMnazi Mmoja Hospital, a tertiary care facility, in Zanzibar, Tanzania.MethodsWe identified all cases of morbidity and mortality in women admitted within 42 days after the end of pregnancy at Mnazi Mmoja Hospital in the period from April to October 2016. The severity of complications was classified using WHO’s near-miss approach definitions: potentially life-threatening condition (PLTC), maternal near-miss (MNM) or maternal death (MD). Quality of in-hospital care was assessed using the mortality index (MI) defined as ratio between mortality and severe maternal outcome (SMO) where SMO = MD + MNM, cause-specific case facility rates and comparison with predicted mortality based on the Maternal Severity Index model.Main outcomes5551 women were included. 569 (10.3%) had a potentially life-threatening condition and 65 (1.2%) a severe maternal outcome (SMO): 37 maternal near-miss cases and 28 maternal deaths. The mortality index was high at 0.43 and similar for women who developed a SMO within 12 hours of admission and women who developed a SMO after 12 hours. A standardized mortality ratio of 6.03 was found; six times higher than that expected in moderate maternal mortality settings given the same severity of cases. Obstetric haemorrhage was found to be the main cause of SMO. Ruptured uterus and admission to ICU had the highest case-fatality rates. Maternal death cases seemed to have received essential interventions less often.ConclusionsWHO’s near-miss approach can be used in this setting. The high mortality index observed shows that in-hospital care is not preventing progression of disease adequately once a severe complication occurs. Almost one in two women experiencing life-threatening complications will die. This is six times higher than in moderate mortality settings.

Maternal near-miss and death incidences – Frequencies, causes and the referral chain in Somaliland: A pilot study using the WHO near-miss approach

Background Somaliland is a self-declared country with a population of 3.5 million. Most of its population reside in rural areas. The objective of this pilot near-miss study was to monitor the frequency and causes of maternal near-miss and deaths and the referral chain for women to access Skilled Birth Attendants (SBA). Method: A facility-based study of all maternal near-miss and mortality cases over 5months using the WHO near-miss tool in a main referral hospital. Reasons for bypassing the Antenatal Care facility (ANC) and late arrival to the referral hospital were investigated through verbal autopsy. Results: One hundred and thirty-eight (138) women with severe maternal complications were identified: 120 maternal near-miss, 18 maternal deaths. There were more near-miss cases on arrival (74.2%) compared with events that developed inside the hospital (25.8%). Likewise, there were more maternal deaths (77.8%) on arrival than was the case during hospitalization (22.2%). The most common mode of referral among maternal near-miss events was family referrals (66.7%). Of 18 maternal deaths, 15 were family referrals. Reasons for bypassing ANC were as follows: lack of confidence in the service provided; lack of financial resources; and lack of time to visit ANC. Reasons for late arrival to the referral hospital were as follows: lack of knowledge and transportation; and poor communication. Conclusion and clinical implication: To increase the utilization of ANC might indirectly lower the number of near-miss and death events. Collaboration between ANC staff and referral hospital staff and a more comprehensive near-miss project are proposed.

"Near-Miss" Obstetric events and maternal mortality in a Tertiary Care Hospital.

Obstetric near-miss or severe acute maternal morbidity is gaining interest internationally as a new indicator of the quality of obstetric care. This is a retrospective study conducted using "The WHO Near-Miss Approach" to provide insight into obstetric emergencies, near-miss cases, and maternal deaths in our hospital. The maternal near-miss ratio was 8.4/1000 live births, maternal near-miss to mortality ratio was 5.3:1. Hemorrhage was the leading cause (43.7%) of morbidity in near-miss cases while hypertensive disorders were the leading cause in maternal deaths (66.6%). Among women with potentially life-threatening conditions, severe preeclampsia was the most common complication (50.54%). The near-miss approach helps to evaluate and improve the quality of care provided by health system by identifying the pattern of severe maternal morbidity and mortality, strengths and weakness in the referral system and the clinical interventions available and the ways in which improvements can be made.

Near-miss Obstetric Events in a Tertiary Care Teaching Hospital in Nepal: An Audit

Aims: This study aims to determine the frequency of near-miss obstetric events and analyze its nature such as reasons for near-miss, organ dysfunction associated and critical management required among pregnant women managed over a 3-year period in a Tertiary Care Teaching Hospital in Nepal. Methods: This hospital based prospective, descriptive study was done from August 2011 to February 2015. Case eligibility was defined by WHO Near-Miss Guidelines. Medical records of the patients and the interview with the patient, accompanying family members and health workers from referral centres were used to generate the data which were filled in the pre-designed questionnaire. The data generated and analyzed included age and gestation weeks, parity, mode of intervention, associated organ dysfunctions, reasons for near-miss and critical intervention accompanied to manage the near-miss cases. Results were presented in mean ± SD and percentages, wherever applicable. Results: There were 4617 deliveries with 28 near-miss cases. The major factors contributing near-miss events were obstetric haemorrhage followed by hypertensive disorder. Three fourth (n=21) of cases required blood transfusion and almost all cases (n=26) required ICU management. Coagulation disorder was observed in majority of cases (n=23) followed by cardiovascular, respiratory and uterine atony. Conclusions: In this study, maternal near-miss event was mainly attributable to obstetric haemorrhage followed by hypertension and sepsis. Major organ-system disorders observed were coagulation disorder, cardiovascular, respiratory and uterine disorders. Almost all the cases were managed in ICU and majority of them required blood transfusion.

Implementation of WHO Near-Miss Approach for Maternal Health at a Tertiary Care Hospital: An Audit.

The objective of this study was to evaluate severe maternal outcomes (including maternal deaths and maternal near-miss cases). A prospective study of severe maternal outcomes (including maternal deaths and maternal near-miss cases) from May 2012 to April 2013 was performed. For each woman, data were collected on the occurrence of selected severe pregnancy-related complications, the use of critical interventions, and admissions to intensive care unit. The total number of deliveries were 2340. The number of maternal deaths was three. The natures of the near-miss cases during the study period were recorded. Prevalence of SAMM (severe acute maternal morbidity) was 2.025%. In areas where the maternal mortality is low, there is a need to shift focus to maternal near-miss cases or SAMM, which is a useful adjunct to maternal death enquiries.

Evaluation of severe maternal outcomes to assess quality of maternal health care at a tertiary center.

Maternal mortality and near-miss index reflect the quality of care provided by a health facility. The World Health Organization recently published near-miss approach where strict near- miss criteria based on markers of organ dysfunction are defined. The aim of the study was to determine the frequency of severe maternal complications, maternal near-miss cases and maternal deaths, to analyze causes of near-miss and maternal mortality and to determine the values of maternal near-miss indicators. This was a prospective observational study conducted at a tertiary care centre in North India from January 2012 - March 2013. WHO's near-miss approach was implemented for evaluation of severe maternal outcomes and to assess the quality of maternal health care. The number of women attending our facility with severe maternal complications was low (205 in 6,767 live births); as a result maternal near-miss ratio (MNMR) was low; 3.98/1,000 live births; Overall Maternal near-miss mortality ratio (MNM:1MD) was also low, 3.37:1, because of strict criterion of labeling near-miss and delay in referral to the hospital. Hypertensive disorder (37.5%) was the commonest underlying cause for maternal mortality. Basic implementation of WHO near-miss approach helped in the systematic identification and evidence-based management of severe maternal complications thereby improving the quality of maternal health in a developing country.

Assessment of maternal near-miss and quality of care in a hospital-based study in Accra, Ghana

ObjectiveTo assess the baseline incidence of maternal near-miss, process indicators related to facility access, and quality of care at a tertiary care facility in urban Ghana. MethodsA prospective observational study of all women delivering at the facility, including those with pregnancy-related complications, was conducted between October 2010 and March 2011. Quality of maternal health care was assessed via a newly developed WHO instrument based on near-miss criteria and criterion-based clinical audit methodology. ResultsAmong 3438 women, 516 had potentially life-threatening conditions and 131 had severe maternal outcomes (94 near-miss cases and 37 maternal deaths). More than half (64.4%) of the women had been referred to the facility. The incidence of maternal near-miss was 28.6 cases per 1000 live births. Anemia contributed to most cases with a severe maternal outcome. More than half of all women with severe maternal outcomes developed organ dysfunction or died within the first 12hours of hospital admission. Although preventive measures were prevalent, treatment-related indicators showed mixed results. ConclusionThe WHO near-miss approach was found to represent a feasible strategy in low-resource countries. Improving referral systems, effective use of critical care, and evidence-based interventions can potentially reduce severe maternal outcomes.

Maternal Near-Miss: A Multicenter Surveillance in Kathmandu Valley

Multicenter surveillance has been carried out on maternal near-miss in the hospitals with sentinel units. Near-miss is recognized as the predictor of level of care and maternal death. Reducing Maternal Mortality Ratio is one of the challenges to achieve Millennium Development Goal. The objective was to determine the frequency and the nature of near-miss events and to analyze the near-miss morbidities among pregnant women. A prospective surveillance was done for a year in 2012 at nine hospitals in Kathmandu valley. Cases eligible by definition were recorded as a census based on WHO near-miss guideline. Similar questionnaires and dummy tables were used to present the results by non-inferential statistics. Out of 157 cases identified with near-miss rate of 3.8 per 1000 live births, severe complications were postpartum hemorrhage 62 (40%) and preeclampsia-eclampsia 25 (17%). Blood transfusion 102 (65%), ICU admission 85 (54%) and surgery 53 (32%) were common critical interventions. Oxytocin was main uterotonic used both prophylactically and therapeutically at health facilities. Total of 30 (19%) cases arrived at health facility after delivery or abortion. MgSO4 was used in all cases of eclampsia. All laparotomies were performed within three hours of arrival. Near-miss to maternal death ratio was 6:1 and MMR was 62. Study result yielded similar pattern amongst developing countries and same near-miss conditions as the causes of maternal death reported by national statistics. Process indicators qualified the recommended standard of care. The near-miss event could be used as a surrogate marker of maternal death and a window for system level intervention.

Listening to women's voices: the quality of care of women experiencing severe maternal morbidity, in Accra, Ghana.

BackgroundWomen who survive severe obstetric complications can provide insight into risk factors and potential strategies for prevention of maternal morbidity as well as maternal mortality. We interviewed 32 women, in an urban facility in Ghana, who had experienced severe morbidity defined using a standardized WHO near-miss definition and identification criteria. Women provided personal accounts of their experiences of severe maternal morbidity and perceptions of the care they received.Methods and FindingsThe study took place in a referral facility in urban Accra, and semi-structured interviews were conducted with women who had either a maternal near miss (n = 17) or a potentially life-threatening complication (n = 15). The most common themes surrounding the traumatic delivery were the fear of dying and concern over the potential (or actual) loss of the baby. For many women, the loss of a baby negatively influenced how they viewed and coped with this experience. Women’s perceptions of the quality of the care highlighted several key factors such as the importance of information, good communication and attitudes, and availability of human (i.e., more doctors) and physical resources (i.e., more beds, water) at the facility.ConclusionsOur results suggest that experiences of women with severe maternal morbidity may inform different aspects of quality improvement in the facilities, which in turn have a positive impact on future health seeking behavior, service utilization and reduction in maternal morbidity and mortality.
