Surgical care data, measured to save lives.
Track the five core surgical indicators — securely, in real time.
Lancet-aligned framework
Built on the global surgery evidence base.
De-identified by design
No patient identifiers ever leave the facility.
Role-based governance
Each tier sees exactly what it should.
Facility to national
One pipeline, every reporting level.
Evidence framework
The five core indicators
Aligned with the global surgery framework, Sigma tracks the metrics that define a functioning surgical system.
Surgical Volume
Procedures per 100,000 population, tracked by facility and specialty.
Perioperative Mortality
POMR monitored transparently to drive safer surgical care.
Workforce Density
Surgeons, anaesthetists and obstetricians per 100,000 population.
Timely Access
Share of the population within two hours of essential surgery.
Financial Protection
Protection from impoverishing and catastrophic health expenditure.
Built for the whole system
Every level of the surgical ecosystem, one source of truth.
Role-based visibility ensures data reaches the people who need it — under strict privacy and governance standards.
National ministries
High-level aggregation for strategic planning and resource allocation.
Facility administrators
Granular case tracking, outcome monitoring and operational efficiency.
Research partners
Standardised, de-identified data for quality studies and benchmarking.
