Demographic Surveillance System (DSS)

CHAMPS conducts demographic surveillance to identify and track all pregnancies, births, deaths, and population numbers in each catchment area. DSS data provide context for how CHAMPS deaths can be interpreted relative to all deaths in each catchment area.
Mortality Surveillance

CHAMPS teams in each site work with community and hospital workers to identify stillbirths and child deaths. Families are approached for consent to participate in CHAMPS and, for deaths that are identified within 24 hours, CHAMPS teams request consent for collection of tissues.
Data Collection

CHAMPS datasets include information from multiple sources. With family consent we collect tissue and body fluid samples that undergo testing. We gather information from clinical records. And through verbal autopsy we record the family’s story. For stillbirth and newborn deaths, we collect maternal clinical information.
Laboratory Work
Tissue and body fluid specimens are submitted to CHAMPS’ labs for the following tests:
- Real-time PCR using Taqman Array (Cards), a platform using customized multiplexed assay that tests for over 100 pathogens.
- Standardized testing for diseases like HIV, malaria, and TB
- Conventional microbiology including culture
- Histopathology examination using routine and special stains and, for certain cases, immunohistochemistry techniques
DeCoDe

The Determination of the Cause of Death (DeCoDe) method uses a multidisciplinary panel of experts who assess information from the verbal autopsy, clinical abstractions (child and maternal), laboratory and pathology results, and any additional information CHAMPS gathers.

The DeCode panel follows the International Classification of Diseases, Tenth Revision (ICD-10) and the World Health Organization (WHO) Medical Certificate of Cause of Death to assign underlying, immediate, and intermediate causes of death for each case.

Case Demographics
- Age, sex, estimated gestational age, and dates of birth and death are included.
- Additional information including body measurements, location of death, and duration of hospitalization are also available for each CHAMPS case.
Verbal Autopsy

This file includes information such as the family’s description of child’s symptoms, the location of death, etc.

Additionally, the CHAMPS data dictionary contains the code legend for survey questions.
TaqMan Array Card Results
TAC results show which pathogens were detected for each specimen type. Below are the number of pathogen results for each specimen:
- Blood: 62 pathogens
- Lung: 47 pathogens
- Cerebrospinal fluid: 62 pathogens
- Rectal swab: 41 pathogens
- Nasopharyngeal/Oropharyngeal swabs: 47 pathogens
The results are used to find how the patient tested for different pathologies.
Clinical Lab Results
- Blood microbiology
- CSF microbiology
- HIV test results
- Malaria test results
- TB test results
DeCoDe Results
- Immediate, intermediate (or morbid) causes of death
- Underlying cause of death
- Maternal health factors that contribute to perinatal death
CHAMPS cause of death categories and associated ICD-10 codes can be found in the CHAMPS Mappings file.
