Area of Science:

  • Public Health
  • Health Services Research
  • Spatial Epidemiology

Background:

  • The Hearing Health Care Network was established to address the needs of individuals with hearing impairments, offering primary, medium, and high-complexity care.
  • Spatial analysis using geoprocessing is crucial for understanding the distribution and organization of these essential health services.

Purpose of the Study:

  • To conduct a spatial analysis of the Hearing Health Care Network in the State of Minas Gerais.
  • To evaluate the organization and accessibility of hearing healthcare services across different regions.

Main Methods:

  • A cross-sectional analytical study employed geoprocessing techniques.
  • Analysis included the frequency of procedures (assessment, diagnosis, hearing aid fitting, follow-up, speech therapy) per capita and in absolute numbers.
  • The health micro-region served as the unit for spatial analysis.

Main Results:

  • Higher absolute frequencies of assessment, diagnosis, hearing aid fitting, and follow-up were observed in micro-regions with existing hearing health services.
  • Speech therapy demonstrated the highest occurrence statewide, both in absolute numbers and per population.
  • Follow-up procedures were found to be the least frequent.

Conclusions:

  • Geoprocessing effectively mapped the care flow based on procedure frequency, population density, and geographic distribution.
  • All services provided by the Hearing Health Care Network are accessible to users throughout all micro-regions of Minas Gerais.
