Area of Science:

  • Medical Geography
  • Public Health
  • Emergency Medicine

Background:

  • Snakebites pose a significant public health risk in Hainan Province.
  • Effective management of snakebites relies on timely access to appropriate antivenom.
  • Assessing spatial accessibility is crucial for optimizing healthcare resource allocation.

Purpose of the Study:

  • To analyze the spatial accessibility of hospitals equipped with various types of snake antivenom in Hainan Province.
  • To evaluate the service level and accessibility from both supply and demand perspectives.
  • To identify areas with limited access to antivenom treatments.

Main Methods:

  • Utilized network analysis and the two-step mobile search method.
  • Analyzed spatial accessibility for different antivenom types (Agkistrodon Hyalys, Naja, Bungarus Multicnctus, Agkistrodon Acutus).
  • Assessed accessibility based on travel time and population distribution.

Main Results:

  • Significant populations require over an hour to reach hospitals with specific antivenoms.
  • Approximately 856,000 people need >1 hour for Agkistrodon Hyalys antivenom.
  • Haikou and Sanya cities exhibit the highest accessibility to antivenom-equipped facilities.

Conclusions:

  • Antivenom accessibility in Hainan Province is unevenly distributed.
  • High accessibility is concentrated in southern and northern regions.
  • Accessibility in other regions requires significant improvement to ensure equitable care.
