Cause of death among infants in rural western China: a community-based study using verbal autopsy

Causes and determinants of infant mortality using verbal autopsy and social autopsy methods in a rural population of Odisha: a community-based matched case-control study

BACKGROUND

The avoidable causes of infant mortality should be identified, and interventions should be made to improve the infant mortality rate. The cause of infant deaths should be assessed in both medical and social contexts.

OBJECTIVES

We aimed to determine the medical causes of infant mortality by verbal autopsy and its determinants in two rural blocks of the Khordha district of Odisha and assess the pathway of care and delay in seeking care for the illness preceding infant death using the three-delay model.

DESIGN

We conducted this community-based matched case-control study to identify the medical causes of infant mortality using the verbal autopsy method along with the identification of delay and pathway of care related to infant deaths using a social autopsy method.

SETTINGS

Two rural blocks of Odisha, India.

PARTICIPANTS

We enumerated 100 infant deaths by active surveillance and data triangulation from Accredited Social Health Activists, Auxiliary Nurse Midwives and block-level health information systems. We selected an equal number of alive infants matched with cases in a 1:1 ratio with regard to age, gender and residential address.

OUTCOME MEASURES

We conducted the verbal autopsy using the Sample Registration System verbal autopsy tool, where the cause of death ascertainment was done by two independently trained physicians followed by adjudication by one senior trained physician in case of conflicts. We used the prevalidated International Network for the Demographic Evaluation of Population and Their Health tool to assess three delays and pathways of care related to infant deaths.

RESULTS

Most infant deaths (70%) happened during the first day of life, and almost 50% of neonatal deaths occurred during the first week of life. The three most common causes of infant mortality were birth asphyxia (30%), pneumonia (18%), prematurity and low birth weight (14%). Larger family size (>5) and the education status of fathers till class 10 were significant determinants of infant mortality. Among the 49 infants whose illnesses were identified at home, 2 died at home without receiving any care. Formal or informal care was sought for 32 and 8 infants, respectively. The median delay was found to be 24 hours for level 1 delay. Level 1 delay was observed for 20 cases (40.8%), with more than 24 hours in decision-making in care-seeking. Thirty-seven (75.5%) sick infants reached the healthcare facility 30 min after deciding to seek care.

CONCLUSION

Birth asphyxia, pneumonia prematurity and low birth weight were found to be the common causes of infant mortality, with larger family sizes and lower education status among fathers being the significant determinants of infant mortality. We observed a significant delay in decision-making regarding seeking care among caregivers of sick infants.

Effectiveness of Lung Ultrasound in Comparison with Chest X-Ray in Diagnosis of Lung Consolidation

BACKGROUND:

Lung ultrasound (US) is an available and inexpensive tool for the diagnosis of community-acquired pneumonia (CAP); it which has no hazards of radiation and can be easily used.

AIM:

To evaluate the efficacy of lung ultrasound in the diagnosis and follow-up of CAP.

PATIENTS AND METHODS:

100 patients aged from 40 to 63 years with a mean age of 52.3 ± 10 years admitted to the Critical Care Department, Cairo University with pictures of CAP. Lung US was performed for all patients initially, then a plain chest X-ray (CXR) was performed. Another lung ultrasound was performed on the 10th day after admission.

RESULTS:

Initial chest X-ray was correlated with the initial chest ultrasound examination in CAP diagnosis (R-value = 0.629, P < 0.001). Cohen’s κ was run to determine if there is an agreement between the findings of the initial chest X-ray findings and those of the initial chest ultrasound in CAP diagnosis. A moderate agreement was found where κ = .567 (95% CI, 0.422 to 0.712) and P < 0.001. Upon initial examination, the CXR diagnosed CAP in 48.0% of patients, while lung US diagnosed the disease in 70% of patients. Moreover, lung US was more sensitive than CXR (P-value < 0.001). Compared to the accuracy of computed tomography (CT) chest (100%) which is the gold standard for CAP diagnosis, the accuracy of lung US was 95.0%, while the accuracy of CXR was 81.0%.

CONCLUSION:

This study proved the effectiveness of lung ultrasound in CAP diagnosis.

Uptake of maternal care and childhood immunization among ethnic minority and Han populations in Sichuan province: a study based on the 2003, 2008 and 2013 health service surveys

Background

China has made remarkable progress in maternal and child health (MCH) over the last thirty years, but socio-economic inequalities persist. Ethnicity has become an important determinant of poor MCH outcomes, but little rigorous analytical work has been done in this area. To understand the socio-economic factors that explain ethnic variation in uptake of MCH care, we report the findings from an analysis in Sichuan province.

Methods

We linked data from the 2003, 2008 and 2013 National Health Service Surveys in Sichuan Province. The ethnic disparities in uptake of maternal care (completing 5 antenatal visits, giving birth in hospital and receiving a caesarean section) and childhood immunization (Bacillus Calmette Guerin (BCG), three doses of diphtheria (DPT) and measles immunization) were examined by geographical (Han district/county vs. ethnic minority county) and individual-based (Han women/children vs. ethnic minority women/children) comparisons. We also examined variation by distance to township and county hospitals, women’s education, parity and age using weighted multilevel Poisson regressions with random intercept at district/county level.

Results

Ethnic inequalities in maternal care were marked, both at the geographical (district/county) and the individual level. The % of births in hospital was 90.7% among women in Han districts, compared to 83.3% among women living in Han counties (crude RR 0.93; 95% CI 0.75–1.15), 53.8% among Han women living in ethnic minority counties (crude RR 0.57; 95% CI 0.36–0.93), and 13.5% among ethnic minority women living in ethnic minority counties (crude RR 0.18; 95% CI 0.06–0.57). Adjusting the analysis for survey year, education, parity and distance to county level hospital weakened the association between geographical/individual ethnicity and uptake of maternity care, but associations remained remarkably strong. Coverage of childhood immunization was much higher than uptake of maternity care, and inequalities by ethnicity were much less pronounced.

Conclusion

Lessons can be learned from China’s successful immunization programme to further reduce inequalities in access to maternity care among ethnic minority populations in remote areas. Bringing the services closer to the women’s homes and strengthening health promotion from the township to the village level may encourage more women to seek antenatal care and give birth in hospital.

Fetal, neonatal, and infant death in central China (Hubei): A 16-year retrospective study of forensic autopsy cases

Data based on forensic autopsy in neonates and infants in China are rare in the literature. The purpose of this study is to evaluate the characteristics of fetal, neonatal, and infant death and to determine the main cause of death among them.A retrospective analysis of fetal and infant forensic autopsies referred to the Tongji Forensic Medical Center (TFMC) in Hubei, central China, during a 16-year period between January 1999 and December 2014, was performed.In this period, there were 1111 males and 543 females; the total male-to-female ratio (MFR) was 2.05:1. There were 173 fetal and infant autopsies conducted, comprised of 43 fetal, 84 neonatal (<28 days) and 46 infant (4 weeks to 1 year) cases. The annual case number ranged from 5 in 2004 to 18 in 2014 (annual mean of 10.8). MFR was 1.75:1. About 94% of these deaths (163/173) resulted from natural causes, 6 cases (3.5%) were accidental deaths, and 4 (2.3%) resulted from homicide (4 abandoned babies). Among fetuses, the most common causes of death were placental and umbilical cord pathologies (28%, 12/43), followed by intrapartum asphyxia resulting from amniotic fluid aspiration (AFA) or meconium aspiration syndrome (MAS) (18.6%, 8/43), congenital malformation (14%, 6/43), and intrapartum infection (9.3%, 4/43). A majority of neonatal deaths (66.7%, 56/84) died within 24 hours of birth. The main causes of neonatal death were asphyxia resulting from AFA, MAS, or hyaline membrane disease, and congenital malformation. The main causes of infant (1-12 months) death were infectious diseases, including pneumonia, meningitis, and viral brainstem encephalitis.This study was the 1st retrospective analysis of autopsies of fetal, neonatal, and infant death in TFMC and central China. We delineate the common causes of early demise among cases referred for autopsy, and report a male preponderance in this population. Our data observed that placental and/or umbilical cord pathology, asphyxia due to AFA, and/or MAS, and pneumonia were the leading causes of fetal, neonatal, and infant death, respectively. And it can inform clinical practitioners about the underlying causes of some of the most distressing cases in their practices.

Reporting of ethics in peer-reviewed verbal autopsy studies: a systematic review

Introduction

Verbal autopsy (VA) is a method that determines the cause of death by interviewing a relative of the deceased about the events occurring before the death, in regions where medical certification of cause of death is incomplete. This paper aims to review the ethical standards reported in peer-reviewed VA studies.

Methods

A systematic review of Medline and Ovid was conducted by two independent researchers. Data were extracted and analysed for articles based on three key areas: Institutional Review Board (IRB) clearance and consenting process; data collection and management procedures, including: time between death and interview; training and education of interviewer, confidentiality of data and data security; and declarations of funding and conflict of interest.

Results

The review identified 802 articles, of which 288 were included. The review found that 48% all the studies reported having IRB clearance or obtaining consent of participants. The interviewer training and education levels were reported in 62% and 21% of the articles, respectively. Confidentiality of data was reported for 14% of all studies, 18% did not report the type of respondent interviewed and 51% reported time between death and the interview for the VA. Data security was reported in 8% of all studies. Funding was declared in 63% of all studies and conflict of interest in 42%. Reporting of all these variables increased over time.

Conclusions

The results of this systematic review show that although there has been an increase in ethical reporting for VA studies, there still remains a large gap in reporting.

Liver transplantation for biliary atresia: A single-center study from mainland China

AIM: To summarize our single-center experience with liver transplantation (LT) for biliary atresia (BA).

METHODS: From October 2006 to December 2012, 188 children with BA were analyzed retrospectively. The stage I group (from October 2006 to December 2010) comprised the first 74 patients, and the stage II group (from January 2011 to December 2012) comprised the remaining 114 patients. Finally, 123 liver transplants were performed in 122 (64.9%) patients, whereas 66 patients did not undergo LT due to denial by their parents or lack of suitable liver grafts. The selection of graft types depended on the patients’ clinical status and whether a suitable living donor was available. The characteristics of patients in stages I and II were described, and the surgical outcomes of LT recipients were compared between the two stages. The Kaplan-Meier method was used to estimate the cumulative patient and graft survival rates, and the equality of survival distributions was evaluated using the log-rank test.

RESULTS: The 188 children consisted of 102 boys and 86 girls. Their ages ranged from 3 to 144 mo with a median of 8 mo. One hundred and fifteen (61.2%) patients were born in rural areas. Comparing stage I and stage II patients, the proportion of patients referred by pediatricians (43.2% vs 71.1%, respectively; P < 0.001) and the proportion of patients who previously received a Kasai procedure (KP) (32.4% vs 44.7%, respectively; P = 0.092) obviously increased, and significantly more parents were willing to treat their children with LT (73% vs 86%, respectively; P = 0.027). Grafts from living donors (102/122, 83.6%) were the most commonly used graft type. Surgical complications (16/25, 64.0%) were the main reason for posttransplant mortality. Among the living donor liver transplantation recipients (n = 102), the incidence of surgical complications was significantly reduced (34.1% vs 15.5%, respectively; P = 0.029) and survival rates of patients and grafts were greatly improved (81.8% vs 89.7%, respectively, at 1 year; 75.0% vs 87.8%, respectively, at 3 years; P = 0.107) from stage I to stage II.

CONCLUSION: The status of surgical treatments for BA has been changing in mainland China. Favorable midterm outcomes after LT were achieved as centers gained greater technical experience.

[Morbidity and risk factors for neonatal mortality in Douala Referral Hospital]

Introduction

Cette étude avait pour but d’étudier la mortalité néonatale hospitalière et les facteurs associés, dans un hôpital de référence de la ville de Douala au Cameroun.

Méthodes

Il s'agit d'une étude de cohorte prospective qui s'est déroulée du 1er janvier au 31 avril 2014 dans l'unité de néonatologie de l'hôpital Laquintinie de Douala. Les nouveau-nés de 0 à 28 jours étaient concernés. Les données sociodémographiques, cliniques et l’évolution hospitalière ont été enregistrées. La durée moyenne d'hospitalisation était de 9,9± 6,9. Les tests du Chi2, de Student et une analyse bivariée ont permis de mesurer les associations entre variables. A l'aide de la régression multivariée les facteurs associés à la mortalité ont été déterminés. Le taux de significativité était de 0,05.

Résultats

Au total,350 nouveau-nés ont été inclus, avec un taux de mortalité de 20,3%. L'hyperthermie était le principal motif de consultation avec 102 (29%) patients. Les principales affections associées au décès étaient: les infections 39 (54,9%) (p = 0,0001), la prématurité 31 (43,6%) (p < 0,05), les troubles de l'adaptation 23 (32,4%) (p < 0,005), les encéphalopathies 5 (7%) (p < 0,005) et le paludisme 5 (7%) (p = 0,03). L'on notait comme facteurs associés à cette mortalité, la naissance hors de l'hôpital 51(71,8%) (p< 0,005), la présentation de siège (p = 0,02), l’âge gestationnel < 0,005), l’âge < 1500g (p < 0,005).

Conclusion

Le contrôle des facteurs associés à la mortalité peut conduire à une réduction de la mortalité néonatale.
