This document describes the development of a country-level index to measure surgical capacity based on indicators from The Lancet Commission on Global Surgery and other global health indicators. Data was collected from global data repositories on indicators like the percentage of general government expenditure spent on health and perioperative mortality rates. Countries were assigned points based on meeting thresholds for each indicator, with a maximum of 5 points per indicator. The index aimed to incorporate Lancet Commission indicators, traditional indicators, and establish goals to measure and monitor surgical capacity over time. Limitations include assumptions about equal weighting of indicators and data reporting gaps. The index could help with resource allocation, policy planning, and monitoring surgical capacity improvements over time.
