Exploring Drivers of Infant Deaths in Rural Rwanda Through Verbal Social Autopsy

Validation of CHERG'S Verbal Autopsy-Social Autopsy (VASA) tool for ascertaining determinants and causes of under-five child mortality in Pakistan

The majority (40%) of the world's under-five mortality burden is concentrated in nations like Nigeria (16.5%), India (16%), Pakistan (8%), and the Democratic Republic of the Congo (6%), where an undetermined number of under-five deaths go unrecorded. In low-resource settings throughout the world, the Verbal Autopsy-Social Autopsy (VASA) technique may assist assess under-five mortality estimates, assigning medical and social causes of death, and identifying relevant determinants. Uncertainty regarding missing data in high-burden nations like Pakistan necessitates a valid and reliable VASA instrument. This is the first study to validate Child Health Epidemiology Reference Group-CHERG's VASA tool globally. In Pakistan, data from such a valid and reliable tool is vital for policy. This paper reports on the VASA tool in Karachi, Pakistan. Validity and reliability of the CHERG VASA tool were tested using face, content, discriminant validation, and reliability tests on one hundred randomly selected mothers who had recently experienced an under-five child death event. Data were computed on SPSS (version-21) and R software. Testing revealed high Item-content Validity Index (I-CVI) (>81.43%); high Cronbach's Alpha (0.843); the accuracy of between 75-100% of the discriminants classifying births to live and stillbirths; and I-CVI (>82.07% and 88.98% respectively) with high accuracy (92% and 97% respectively) for assigning biological and social causes of child deaths, respectively. The CHERG VASA questionnaire was found relevant to the conceptual framework and valid in Pakistan. This valid tool can assign accurate medical and non-medical causes of child mortality cases occurring in Pakistan.

Place of death, care-seeking and care pathway progression in the final illnesses of children under five years of age in sub-Saharan Africa: a systematic review

Background

Half of all under-5 deaths occur in sub-Saharan Africa. Reducing child mortality requires understanding of the modifiable factors that contribute to death. Social autopsies collect information about place of death, care-seeking and care-provision, but this has not been pooled to learn wider lessons. We therefore undertook a systematic review to collect, evaluate, map, and pool all the available evidence for sub-Saharan Africa.

Methods

We searched PubMed, Embase, Global Health, the Cochrane Library and grey literature for studies relating to under-5 deaths in sub-Saharan Africa with information on place of death and/or care-seeking during a child’s final illness. We assessed study quality with a modified Axis tool. We pooled proportions using random effects meta-analysis for place of death and for each stage of the Pathways to Survival framework. Pre-specified subgroup analysis included age group, national income and user-fee policy. We explored heterogeneity with meta-regression. Our protocol was published prospectively (CRD42018111484).

Results

We included 34 studies from 17 countries. Approximately half of the children died at home, irrespective of age. More children died at home in settings with user-fees (69.1%, 95% confidence interval (CI) = 56.2-80.6, I² = 98.4%) compared to settings without user-fees (43.8%, 95% CI = 34.3-53.5, I² = 96.7%). Signs of illness were present in over 95% of children but care-seeking differed by age. 40.1% of neonates (95% CI = 20.7-61.3, I² = 98.0%) died without receiving any care, compared to 6.4% of older children (95% CI = 4.2%-9.0%, I² = 90.6%). Care-seeking outside the home was less common in neonatal deaths (50.5%, 95% CI = 35.6-65.3, I² = 98.3%) compared to infants and young children (82.4%, 95% CI = 79.4%-85.2%, I² = 87.5%). In both age groups, most children were taken for formal care. Healthcare facilities discharged 69.6% of infants and young children who arrived alive (95% CI = 59.6-78.7, I² = 95.5%), of whom only 34.9% were referred for further care (95% CI = 15.1-57.9, I² = 98.7%).

Conclusions

Despite similar distributions in place of death for neonates and infants and young children, care-seeking behaviour differed by age groups. Poor illness recognition is implicated in neonatal deaths, but death despite care-seeking implies inadequate quality care and referral for older children. Understanding such care-seeking patterns enables targeted interventions to reduce under-5 mortality across the region.

Causes of death and predictors of childhood mortality in Rwanda: a matched case-control study using verbal social autopsy

Background

Rwanda has dramatically reduced child mortality, but the causes and sociodemographic drivers for mortality are poorly understood.

Methods

We conducted a matched case-control study of all children who died before 5 years of age in eastern Rwanda between 1st March 2013 and 28th February 2014 to identify causes and risk factors for death. We identified deaths at the facility level and via a community health worker reporting system. We used verbal social autopsy to interview caregivers of deceased children and controls matched by area and age. We used InterVA4 to determine probable causes of death and cause-specific mortality fractions, and utilized conditional logistic regression to identify clinical, family, and household risk factors for death.

Results

We identified 618 deaths including 174 (28.2%) in neonates and 444 (71.8%) in non-neonates. The most commonly identified causes of death were pneumonia, birth asphyxia, and meningitis among neonates and malaria, acute respiratory infections, and HIV/AIDS-related death among non-neonates. Among neonates, 54 (31.0%) deaths occurred at home and for non-neonates 242 (54.5%) deaths occurred at home. Factors associated with neonatal death included home birth (aOR: 2.0; 95% CI: 1.4–2.8), multiple gestation (aOR: 2.1; 95% CI: 1.3–3.5), both parents deceased (aOR: 4.7; 95% CI: 1.5–15.3), mothers non-use of family planning (aOR: 0.8; 95% CI: 0.6–1.0), lack of accompanying person (aOR: 1.6; 95% CI: 1.1–2.1), and a caregiver who assessed the medical services they received as moderate to poor (aOR: 1.5; 95% CI: 1.2–1.9). Factors associated with non-neonatal deaths included multiple gestation (aOR: 2.8; 95% CI: 1.7–4.8), lack of adequate vaccinations (aOR: 1.7; 95% CI: 1.2–2.3), household size (aOR: 1.2; 95% CI: 1.0–1.4), maternal education levels (aOR: 1.9; 95% CI: 1.2–3.1), mothers non-use of family planning (aOR: 1.6; 95% CI: 1.4–1.8), and lack of household electricity (aOR: 1.4; 95% CI: 1.0–1.8).

Conclusion

In the context of rapidly declining childhood mortality in Rwanda and increased access to health care, we found a large proportion of remaining deaths occur at home, with home deliveries still representing a significant risk factor for neonatal death. The major causes of death at a population level remain largely avoidable communicable diseases. Household characteristics associated with death included well-established socioeconomic and care-seeking risk factors.
