Community engagement in maternal and perinatal death surveillance and response (MPDSR): Realist review protocol.

Background: While there has been a decline in maternal and perinatal mortality, deaths remain high in sub-Saharan Africa and Asia. With the sustainable development goals (SDGs) targets to reduce maternal and perinatal mortality, more needs to be done to accelerate progress and improve survival. Maternal and perinatal death surveillance and response (MPDSR) is a strategy to identify the clinical and social circumstances that contribute to maternal and perinatal deaths. Through MPDSR, an active surveillance and response cycle is established by bringing together different stakeholders to review and address these social and clinical factors. Community engagement in MPDSR provides a strong basis for collective action to address social factors and quality of care issues that contribute to maternal and perinatal deaths. Studies have shown that community members can support identification and reporting of maternal and/or perinatal deaths. Skilled care at birth has been increasing globally, but there are still gaps in quality of care. Through MPDSR, community members can collaborate with health workers to improve quality of care. But we do not know how community engagement in MPDSR works in practice; for whom it works and what aspects work (or do not work) and why. This realist review answers the question: which strategies of community engagement in MPDSR produce which outcomes in which contexts? Methods : For this realist review, we will identify published and grey literature by searching relevant databases for articles. We will include papers published from 2004 in all languages and from all countries. We have set up an advisory group drawn from academia, international organizations, and practitioners of both MPDSR and community engagement to guide the process. Conclusion: This protocol and the subsequent realist review will use theoretical approaches from the community engagement literature to generate theory on community engagement in MPDSR.

Design and implementation of a community-based mother-to-mother peer support programme for the follow-up of low birthweight infants in rural western Kenya.

Background: Globally, low birthweight (LBW) infants (<2,500 g) have the highest risk of mortality during the first year of life. Those who survive often have adverse health outcomes. Post-discharge outcomes of LBW infants in impoverished communities in Africa are largely unknown. This paper describes the design and implementation of a mother-to-mother peer training and mentoring programme for the follow-up of LBW infants in rural Kenya. Methods: Key informant interviews were conducted with 10 mothers of neonates (infants <28 days) from two rural communities in western Kenya. These data informed the identification of key characteristics required for mother-to-mother peer supporters (peer mothers) following up LBW infants post discharge. Forty potential peer mothers were invited to attend a 5-day training programme that focused on three main themes: supportive care using appropriate communication, identification of severe illness, and recommended care strategies for LBW infants. Sixteen peer mothers were mentored to conduct seven community follow-up visits to each mother-LBW infant pair with fifteen completing all the visits over a 6-month period. A mixed methods approach was used to evaluate the implementation of the programme. Quantitative data of peer mother socio-demographic characteristics, recruitment, and retention was collected. Two post-training focus group discussions were conducted with the peer mothers to explore their experiences of the programme. Descriptive statistics were generated from the quantitative data and the qualitative data was analysed using a thematic framework. Results: The median age of the peer mothers was 26 years (range 21-43). From March-August 2019, each peer mother conducted a median of 28 visits (range 7-77) with fourteen (88%) completing all their assigned follow-up visits. Post training, our interviews suggest that peer mothers felt empowered to promote appropriate infant feeding practices. They gave multiple examples of improved health seeking behaviours as a result of the peer mother training programme. Conclusion: Our peer mother training programme equipped peer mothers with the knowledge and skills for the post-discharge follow-up of LBW infants in this rural community in Kenya. Community-based interventions for LBW infants, delivered by appropriately trained peer mothers, have the potential to address the current gaps in post-discharge care for these infants.

International virtual confidential reviews of infection-related maternal deaths and near-miss in 11 low- and middle-income countries - case report series and suggested actions.

BACKGROUND: Obstetric infections are the third most common cause of maternal mortality, with the largest burden in low and middle-income countries (LMICs). We analyzed causes of infection-related maternal deaths and near-miss identified contributing factors and generated suggested actions for quality of care improvement. METHOD: An international, virtual confidential enquiry was conducted for maternal deaths and near-miss cases that occurred in 15 health facilities in 11 LMICs reporting at least one death within the GLOSS study. Facility medical records and local review committee documents containing information on maternal characteristics, timing and chain of events, case management, outcomes, and facility characteristics were summarized into a case report for each woman and reviewed by an international external review committee. Modifiable factors were identified and suggested actions were organized using the three delays framework. RESULTS: Thirteen infection-related maternal deaths and 19 near-miss cases were reviewed in 20 virtual meetings by an international external review committee. Of 151 modifiable factors identified during the review, delays in receiving care contributed to 71/85 modifiable factors in maternal deaths and 55/66 modifiable factors in near-miss cases. Delays in reaching a GLOSS facility contributed to 5/85 and 1/66 modifiable factors for maternal deaths and near-miss cases, respectively. Two modifiable factors in maternal deaths were related to delays in the decision to seek care compared to three modifiable factors in near-miss cases. Suboptimal use of antibiotics, missing microbiological culture and other laboratory results, incorrect working diagnosis, and infrequent monitoring during admission were the main contributors to care delays among both maternal deaths and near-miss cases. Local facility audits were conducted for 2/13 maternal deaths and 0/19 near-miss cases. Based on the review findings, the external review committee recommended actions to improve the prevention and management of maternal infections. CONCLUSION: Prompt recognition and treatment of the infection remain critical addressable gaps in the provision of high-quality care to prevent and manage infection-related severe maternal outcomes in LMICs. Poor uptake of maternal death and near-miss reviews suggests missed learning opportunities by facility teams. Virtual platforms offer a feasible solution to improve routine adoption of confidential maternal death and near-miss reviews locally.

Implementation and evaluation of obstetric early warning systems in tertiary care hospitals in Nigeria.

Obstetric Early Warning Systems (EWS) use combined clinical observations to predict increased risk of deterioration and alert health workers to institute actions likely to improve outcomes. The objective of this study was to explore the experience of health workers about the implementation of an obstetric EWS and assess its effectiveness as an alternative clinical monitoring method compared to standard practice. This mixed-method study included obstetric admissions (n = 2400) to inpatient wards between 01/08/2018 and 31/03/2019 at three Nigerian tertiary hospitals (1 intervention and two control). Outcomes assessed were the efficiency of monitoring and recording vital signs using the patient monitoring index and speed of post-EWS trigger specialist review. These were evaluated through a review of case notes before and four months after EWS was introduced. Qualitative data was collected to explore healthcare workers' views on EWS' acceptability and usability. EWS was correctly used in 51% (n = 307) of the women in the intervention site. Of these women, 58.6% (n = 180) were predicted to have an increased risk of deterioration, and 38.9% (n = 70) were reviewed within 1 hour. There was a significant improvement in the frequency of vital signs recording in the intervention site: observed/expected frequency improved to 0.91 from 0.57, p<0.005, but not in the control sites. Health workers reported that the EWS helped them cope with work demands while making it easier to detect and manage deteriorating patients. Nurses and doctors reported that the EWS was easy to use and that scores consistently correlated with the clinical picture of patients. Identified challenges included rotation of clinical staff, low staffing numbers and reduced availability of monitoring equipment. The implementation of EWS improved the frequency of patient monitoring, but a larger study will be required to explore the effect on health outcomes. The EWS is a feasible and acceptable tool in low-resource settings with implementation modifications. Trial registration: ISRCTN, ISRCTN15568048.

WHO global vaccine safety multi-country collaboration project on safety in pregnancy: Assessing the level of diagnostic certainty using standardized case definitions for perinatal and neonatal outcomes and maternal immunization.

Standardized case definitions strengthen post-marketing safety surveillance of new vaccines by improving generated data, interpretation and comparability across surveillance systems. The Global Alignment of Immunization Safety Assessment in Pregnancy (GAIA) project developed standardized case definitions for 21 key obstetric and neonatal terms following the Brighton Collaboration (BC) methodology. In this prospective cohort study, we assessed the applicability of GAIA definitions for maternal immunization exposure and for low birth weight (LBW), preterm birth, small for gestational age (SGA), stillbirth, neonatal death, neonatal infection, and congenital microcephaly. We identified the missing data elements that prevented identified cases and exposures from meeting the case definition (level 1-3 of BC diagnostic certainty). Over a one-year period (2019-2020), all births occurring in 21 sites (mostly secondary and tertiary hospitals) in 6 Low Middle Income Countries and 1 High Income Country were recorded and the 7 perinatal and neonatal outcome cases were identified from routine medical records. Up to 100 cases per outcome were recruited sequentially from each site. Most cases recruited for LBW, preterm birth and neonatal death met the GAIA case definitions. Birth weight, a key parameter for all three outcomes, was routinely recorded at all sites. The definitions for SGA, stillbirth, neonatal infection (particularly meningitis and respiratory infection) and congenital microcephaly were found to be less applicable. The main barrier to obtaining higher levels of diagnostic certainty was the lack of sonographic documentation of gestational age in first or second trimester. The definition for maternal immunization exposure was applicable, however, the highest level of diagnostic certainty was only reached at two sites. Improved documentation of maternal immunization will be important for vaccine safety studies. Following the field-testing of these 8 GAIA definitions, several improvements are suggested that may lead to their easier implementation, increased standardization and hence comparison across studies.

A case for updating the WHO Safe Childbirth Checklist to improve newborn care: Experience from seven Asia and Pacific countries.

The WHO Safe Childbirth Checklist (the SCC) is a clinical tool developed to help health workers follow evidence-based maternal and perinatal care practices at childbirth. Newborn delivery care practices at facilities in seven countries in East Asia and the Pacific were compared to practices checked by the SCC. The analysis found that the SCC does not incorporate several key evidence-based practices around birth demonstrated to prevent newborn morbidity or mortality, or harmful practices associated with increased risks. A revision of the standard SCC is needed to maximise its potential to improve newborn outcomes. This can be initiated under the coordinating umbrella of WHO, but must ensure that the realities of labour and childbirth practices in low- and middle-income countries are considered and addressed.

Development and validation of an obstetric early warning system model for use in low resource settings.

BACKGROUND: The use of obstetric early-warning-systems (EWS) has been recommended to improve timely recognition, management and early referral of women who have or are developing a critical illness. Development of such prediction models should involve a statistical combination of predictor clinical observations into a multivariable model which should be validated. No obstetric EWS has been developed and validated for low resource settings. We report on the development and validation of a simple prediction model for obstetric morbidity and mortality in resource-limited settings. METHODS: We performed a multivariate logistic regression analysis using a retrospective case-control analysis of secondary data with clinical indices predictive of severe maternal outcome (SMO). Cases for design and validation were randomly selected (n = 500) from 4360 women diagnosed with SMO in 42 Nigerian tertiary-hospitals between June 2012 and mid-August 2013. Controls were 1000 obstetric admissions without SMO diagnosis. We used clinical observations collected within 24 h of SMO occurrence for cases, and normal births for controls. We created a combined dataset with two controls per case, split randomly into development (n = 600) and validation (n = 900) datasets. We assessed the model's validity using sensitivity and specificity measures and its overall performance in predicting SMO using receiver operator characteristic (ROC) curves. We then fitted the final developmental model on the validation dataset and assessed its performance. Using the reference range proposed in the United Kingdom Confidential-Enquiry-into-Maternal-and-Child-Health 2007-report, we converted the model into a simple score-based obstetric EWS algorithm. RESULTS: The final developmental model comprised abnormal systolic blood pressure-(SBP > 140 mmHg or < 90 mmHg), high diastolic blood pressure-(DBP > 90 mmHg), respiratory rate-(RR > 40/min), temperature-(> 38 °C), pulse rate-(PR > 120/min), caesarean-birth, and the number of previous caesarean-births. The model was 86% (95% CI 81-90) sensitive and 92%- (95% CI 89-94) specific in predicting SMO with area under ROC of 92% (95% CI 90-95%). All parameters were significant in the validation model except DBP. The model maintained good discriminatory power in the validation (n = 900) dataset (AUC 92, 95% CI 88-94%) and had good screening characteristics. Low urine output (300mls/24 h) and conscious level (prolonged unconsciousness-GCS < 8/15) were strong predictors of SMO in the univariate analysis. CONCLUSION: We developed and validated statistical models that performed well in predicting SMO using data from a low resource settings. Based on these, we proposed a simple score based obstetric EWS algorithm with RR, temperature, systolic BP, pulse rate, consciousness level, urinary output and mode of birth that has a potential for clinical use in low-resource settings..

'Sometimes you are forced to play God ': a qualitative study of healthcare worker experiences of using continuous positive airway pressure in newborn care in Kenya.

​OBJECTIVE: To explore the experiences of using continuous positive airway pressure (CPAP) in newborn care among healthcare workers in Kenya, and to identify factors that would promote successful scale-up. ​DESIGN AND SETTING: A qualitative study using key informant interviews and focus group discussions, based at secondary and tertiary level hospitals in Kenya. ​PARTICIPANTS: Healthcare workers in the newborn units providing CPAP. ​PRIMARY AND SECONDARY OUTCOME MEASURE: Facilitators and barriers of CPAP use in newborn care in Kenya. ​RESULTS: 16 key informant interviews and 15 focus group discussions were conducted across 19 hospitals from September 2017 to February 2018. Main barriers reported were: (1) inadequate infrastructure to support the effective delivery of CPAP, (2) shortage of skilled staff rendering it difficult for the available staff to initiate or monitor infants on CPAP and (3) inadequate knowledge and training of staff that inhibited the safe care of infants on CPAP. Key facilitators reported were positive patient outcomes after CPAP use that increased staff confidence and partnership with caregivers in the management of newborns on CPAP. Healthcare workers in private/mission hospitals had more positive experiences of using CPAP in newborn care as the relevant support and infrastructure were available. ​CONCLUSION: CPAP use in newborn care is valued by healthcare workers in Kenya. However, we identified key challenges that threaten its safe use and sustainability. Further scale-up of CPAP in newborn care should ensure that staff members have ready access to optimal training on CPAP and that there are enough resources and infrastructure to support its use. ETHICS: This study was approved through the appropriate ethics committees in Kenya and the UK (see in text) with written informed consent for each participant.

Building capacities of Auxiliary Nurse Midwives (ANMs) through a complementary mix of directed and self-directed skill-based learning-A case study in Pune District, Western India.

Auxiliary nurse midwives (ANMs) play a pivotal role in provision of maternal and newborn health at primary level in India. Effective in-service training is crucial for upgrading their knowledge and skills for providing appropriate healthcare services. This paper aims at assessing the effectiveness of a complementary mix of directed and self-directed learning approaches for building essential maternal and newborn health-related skills of ANMs in rural Pune District, India. METHODS: During directed learning, the master trainers trained ANMs through interactive lectures and skill demonstrations. Improvement and retention of knowledge and skills and feedback were assessed quantitatively using descriptive statistics. Significant differences at the 0.05 level using the Kruskal-Wallis test were analysed to compare improvement across age, years of experience, and previous training received. The self-directed learning approach fulfilled their learning needs through skills mall, exposure visits, newsletter, and participation in conference. Qualitative data were analysed thematically for perspectives and experiences of stakeholders. The Kirkpatrick model was used for evaluating the results. RESULTS: Directed and self-directed learning was availed by 348 and 125 rural ANMs, respectively. Through the directed learning, ANMs improved their clinical skills like maternal and newborn resuscitation and eclampsia management. Less work experience showed relatively higher improvement in skills, but not in knowledge. 56.6% ANMs either improved or retained their immediate post-training scores after 3 months. Self-directed learning helped them for experience sharing, problem-solving, active engagement through skill demonstrations, and formal presentations. The conducive learning environment helped in reinforcement of knowledge and skills and in building confidence. This intervention could evaluate application of skills into practice to a limited extent. CONCLUSIONS: In India, there are some ongoing initiatives for building skills of the ANMs like skilled birth attendance and training in skills lab. However, such a complementary mix of skill-based 'directed' and 'self-directed' learning approaches could be a plausible model for building capacities of health workforce. In view of the transforming healthcare delivery system in India and the significant responsibility that rests on the shoulder of ANMs, a transponder mechanism to implement skill building exercises at regular intervals through such innovative approaches should be a priority.

Availability and use of continuous positive airway pressure (CPAP) for neonatal care in public health facilities in India: a cross-sectional cluster survey.

OBJECTIVES: To determine the availability of continuous positive airway pressure (CPAP) and to provide an overview of its use in neonatal units in government hospitals across India. SETTING: Cross-sectional cluster survey of a nationally representative sample of government hospitals from across India. PRIMARY OUTCOMES: Availability of CPAP in neonatal units. SECONDARY OUTCOMES: Proportion of hospitals where infrastructure and processes to provide CPAP are available. Case fatality rates and complication rates of neonates treated with CPAP. RESULTS: Among 661 of 694 government hospitals with neonatal units that provided information on availability of CPAP for neonatal care, 68.3% of medical college hospitals (MCH) and 36.6% of district hospitals (DH) used CPAP in neonates. Assessment of a representative sample of 142 hospitals (79 MCH and 63 DH) showed that air-oxygen blenders were available in 50.7% (95% CI 41.4% to 60.9%) and staff trained in the use of CPAP were present in 56.0% (45.8% to 65.8%) of hospitals. The nurse to patient ratio was 7.3 (6.4 to 8.5) in MCH and 6.6 (5.5 to 8.3) in DH. Clinical guidelines were available in 31.0% of hospitals (22.2% to 41.4%). Upper oxygen saturation limits of above 94% were used in 72% (59.8% to 81.6%) of MCH and 59.3% (44.6% to 72.5%) of DH. Respiratory circuits were reused in 53.8% (42.3% to 63.9%) of hospitals. Case fatality rate for neonates treated with CPAP was 21.4% (16.6% to 26.2%); complication rates were 0.7% (0.2% to 1.2%) for pneumothorax, 7.4% (0.9% to 13.9%) for retinopathy and 1.4% (0.7% to 2.1%) for bronchopulmonary dysplasia. CONCLUSIONS: CPAP is used in neonatal units across government hospitals in India. Neonates may be overexposed to oxygen as the means to detect and treat consequences of oxygen toxicity are insufficient. Neonates may also be exposed to nosocomial infections by reuse of disposables. Case fatality rates for neonates receiving CPAP are high. Complications might be under-reported. Support to infrastructure, training, guidelines implementation and staffing are needed to improve CPAP use.

Understanding cause of stillbirth: a prospective observational multi-country study from sub-Saharan Africa.

BACKGROUND: Every year, an estimated 2.6 million stillbirths occur worldwide, with up to 98% occurring in low- and middle-income countries (LMIC). There is a paucity of primary data on cause of stillbirth from LMIC, and particularly from sub-Saharan Africa to inform effective interventions. This study aimed to identify the cause of stillbirths in low- and middle-income settings and compare methods of assessment. METHODS: This was a prospective, observational study in 12 hospitals in Kenya, Malawi, Sierra Leone and Zimbabwe. Stillbirths (28 weeks or more) were reviewed to assign the cause of death by healthcare providers, an expert panel and by using computer-based algorithms. Agreement between the three methods was compared using Kappa (κ) analysis. Cause of stillbirth and level of agreement between the methods used to assign cause of death. RESULTS: One thousand five hundred sixty-three stillbirths were studied. The stillbirth rate (per 1000 births) was 20.3 in Malawi, 34.7 in Zimbabwe, 38.8 in Kenya and 118.1 in Sierra Leone. Half (50.7%) of all stillbirths occurred during the intrapartum period. Cause of death (range) overall varied by method of assessment and included: asphyxia (18.5-37.4%), placental disorders (8.4-15.1%), maternal hypertensive disorders (5.1-13.6%), infections (4.3-9.0%), cord problems (3.3-6.5%), and ruptured uterus due to obstructed labour (2.6-6.1%). Cause of stillbirth was unknown in 17.9-26.0% of cases. Moderate agreement was observed for cause of stillbirth as assigned by the expert panel and by hospital-based healthcare providers who conducted perinatal death review (κ = 0.69; p < 0.0005). There was only minimal agreement between expert panel review or healthcare provider review and computer-based algorithms (κ = 0.34; 0.31 respectively p < 0.0005). CONCLUSIONS: For the majority of stillbirths, an underlying likely cause of death could be determined despite limited diagnostic capacity. In these settings, more diagnostic information is, however, needed to establish a more specific cause of death for the majority of stillbirths. Existing computer-based algorithms used to assign cause of death require revision.

Factors governing the performance of Auxiliary Nurse Midwives in India: A study in Pune district.

BACKGROUND: The Auxiliary nurse midwife (ANM) cadre was created to focus on maternal and child health. ANMs are respected members of their communities and established providers of maternal and child health care within the community and at the facility level. Over time, additional roles and responsibilities have been added. Despite the importance of ANMs in the primary healthcare system in India, studies that consider factors governing the performance of ANMs in their workplaces are limited. We aimed to study factors governing performance of ANMs in Pune district, India. METHODS: Semi-structured interviews were conducted with 13 purposely selected key informants at facility, district, state, and national levels. Focus group discussions were conducted with 41 ANMs and 25 members of the community. Non-participatory observations with eight ANMs provided information to expand on and scrutinise findings that emerged from the other lines of inquiry. A realist lens was applied to identify ANMs' performance as a result of "mechanisms" (training, supervision, accountability mechanisms) within the given "context" (regulatory system, infrastructure and resources, ANMs' expanded scope of work, gender roles and norms). RESULTS: Weak enforcement of regulatory system led to poor standardisation of training quality among training institutions. Challenges in internal accountability mechanisms governing ANMs within the health system hierarchy made it difficult to ensure individual accountability. Training and supervision received were inadequate to address current responsibilities. The supervisory approach focused on comparing information in periodic reports against expected outputs. Clinical support in workplaces was insufficient, with very little problem identification and solving. CONCLUSION: Focusing on the tasks of ANMs with technical inputs alone is insufficient to achieve the full potential of ANMs in a changing context. Systematic efforts tackling factors governing ANMs in their workplaces can produce a useful cadre, that can play an important role in achieving universal health coverage in India.

Poor availability of essential medicines for women and children threatens progress towards Sustainable Development Goal 3 in Africa.

BACKGROUND: Most maternal and child deaths are preventable or treatable with proven, cost-effective interventions for infectious diseases and maternal and neonatal complications. In 2015 sub-Saharan Africa accounted for up to 66% of global maternal deaths and half of the under-five deaths. Access to essential medicines and commodities and trained healthcare workers to provide life-saving maternal, newborn and post-natal care are central to further reductions in maternal and child mortality. METHODS: Available data for 24 priority medicines for women and children were extracted from WHO service availability and readiness assessments conducted between 2012 and 2015 for eight countries in sub-Saharan Africa. The mean availability of medicines in facilities stating they provide services for women or children and differences by facility type, ownership and location are reported. RESULTS: The mean availability of 12 priority essential medicines for women ranged from 22% to 40% (median 33%; IQR 12%) and 12 priority medicines for children ranged from 28% to 57% (median 50%; IQR 14%). Few facilities (<1%) had all nominated medicines available. There was higher availability of priority medicines for women in hospitals than in primary care facilities: range 32%-80% (median 61%) versus 20%-39% (median 23%) and for children's medicines 31%-71% (median 58%) versus 27%-57% (median 48%). Availability was higher in public than private facilities: for women's medicines, range 21%-41% (median 34%) versus 4%-36% (median 27%) and for children's medicines 28%-58% (median 51%) versus 5%-58% (median 46%). Patterns were mixed for rural and urban location for the priority medicines for women, but similar for children's medicines. CONCLUSIONS: The survey results show unacceptably low availability of priority medicines for women and children in the eight countries. Governments should ensure the availability of medicines for mothers and children if they are to achieve the health sustainable development goals.

Early warning systems in obstetrics: A systematic literature review.

INTRODUCTION: Several versions of Early Warning Systems (EWS) are used in obstetrics to detect and treat early clinical deterioration to avert morbidity and mortality. EWS can potentially be useful to improve the quality of care and reduce the risk of maternal mortality in resource-limited settings. We conducted a systematic literature review of published obstetric early warning systems, define their predictive accuracy for morbidity and mortality, and their effectiveness in triggering corrective actions and improving health outcomes. METHODS: We systematically searched for primary research articles on obstetric EWS published in peer-reviewed journals between January 1997 and March 2018 in Medline, CINAHL, SCOPUS, Science Direct, and Science Citation Index. We also searched reference lists of relevant articles and websites of professional societies. We included studies that assessed the predictive accuracy of EWS to detect clinical deterioration, or/and their effectiveness in improving clinical outcomes in obstetric inpatients. We excluded studies with a paediatric or non-obstetric adult population. Cross-sectional and qualitative studies were also excluded. We performed a narrative synthesis since the outcomes reported were heterogeneous. RESULTS: A total of 381 papers were identified, 17 of which met the inclusion criteria. Eleven of the included studies evaluated the predictive accuracy of EWS for obstetric morbidity and mortality, 5 studies assessed the effectiveness of EWS in improving clinical outcomes, while one study addressed both. Sixteen published EWS versions were reviewed, 14 of which included five basic clinical observations (pulse rate, respiratory rate, temperature, blood pressure, and consciousness level). The obstetric EWS identified had very high median (inter-quartile range) sensitivity-89% (72% to 97%) and specificity-85% (67% to 98%) but low median (inter-quartile range) positive predictive values-41% (25% to 74%) for predicting morbidity or ICU admission. Obstetric EWS had a very high accuracy in predicting death (AUROC >0.80) among critically ill obstetric patients. Obstetric EWS improves the frequency of routine vital sign observation, reduces the interval between the recording of specifically defined abnormal clinical observations and corrective clinical actions, and can potentially reduce the severity of obstetric morbidity. CONCLUSION: Obstetric EWS are effective in predicting severe morbidity (in general obstetric population) and mortality (in critically ill obstetric patients). EWS can contribute to improved quality of care, prevent progressive obstetric morbidity and improve health outcomes. There is limited evidence of the effectiveness of EWS in reducing maternal death across all settings. Clinical parameters in most obstetric EWS versions are routinely collected in resource-limited settings, therefore implementing EWS may be feasible in such settings.

Application of the ICD-PM classification system to stillbirth in four sub-Saharan African countries.

OBJECTIVE: To identify the causes and categories of stillbirth using the Application of ICD-10 to Deaths during the Perinatal Period (ICD-PM). METHODS: Prospective, observational study in 12 hospitals across Kenya, Malawi, Sierra Leone and Zimbabwe. Healthcare providers (HCPs) assigned cause of stillbirth following perinatal death audit. Cause of death was classified using the ICD-PM classification system. FINDINGS: 1267 stillbirths met the inclusion criteria. The stillbirth rate (per 1000 births) was 20.3 in Malawi (95% CI: 15.0-42.8), 34.7 in Zimbabwe (95% CI: 31.8-39.2), 38.8 in Kenya (95% CI: 33.9-43.3) and 118.1 in Sierra Leone (95% CI: 115.0-121.2). Of the included cases, 532 (42.0%) were antepartum deaths, 643 (50.7%) were intrapartum deaths and 92 cases (7.3%) could not be categorised by time of death. Overall, only 16% of stillbirths could be classified by fetal cause of death. Infection (A2 category) was the most commonly identified cause for antepartum stillbirths (8.6%). Acute intrapartum events (I3) accounted for the largest proportion of intrapartum deaths (31.3%). In contrast, for 76% of stillbirths, an associated maternal condition could be identified. The M1 category (complications of placenta, cord and membranes) was the most common category assigned for antepartum deaths (31.1%), while complications of labour and delivery (M3) accounted for the highest proportion of intrapartum deaths (38.4%). Overall, the proportion of cases for which no fetal or maternal cause could be identified was 32.6% for antepartum deaths, 8.1% for intrapartum deaths and 17.4% for cases with unknown time of death. CONCLUSION: Clinical care and documentation of this care require strengthening. Diagnostic protocols and guidelines should be introduced more widely to obtain better data on cause of death, especially antepartum stillbirths. Revision of ICD-PM should consider an additional category to help accommodate stillbirths with unknown time of death.
