Summary
This summary is machine-generated.

Globally, 4.8 billion people lack access to essential surgical care, highlighting a critical health inequity. Improving surgical services is vital for achieving universal health coverage and ensuring equitable healthcare for all populations.

Area of Science:

  • Global Health
  • Surgical Access
  • Health Equity

Background:

  • Over 2 billion people lack surgical care access based on operating theatre density.
  • The Lancet Commission on Global Surgery advocates for universal access to safe, affordable surgical and anesthesia care.
  • Estimating the global population without access to surgical services is crucial.

Purpose of the Study:

  • To estimate the number of individuals worldwide lacking access to surgical services.
  • To assess surgical access based on the Lancet Commission's vision of universal care.
  • To identify disparities in surgical care availability globally.

Main Methods:

  • A statistical model was developed to estimate surgical access in 196 countries.
  • Access was evaluated across four dimensions: timeliness, capacity, safety, and affordability.

  • Probabilistic sensitivity analysis and multiple imputation were used to account for uncertainty and missing data.

    • Main Results:

    • At least 4.8 billion people (67% of the global population) lack access to surgery.
    • Significant regional disparities exist, with over 95% lacking access in South Asia and parts of sub-Saharan Africa.
    • Less than 5% lack access in high-income regions like Australasia, North America, and Western Europe.

    Conclusions:

    • The majority of the world's population lacks access to surgical care, with highly inequitable distribution.
    • The lack of surgical access in low- and middle-income countries constitutes a major global health crisis.
    • Increasing surgical service access is essential for achieving universal health coverage and global health equity.
