Socio-economic variation in CT scanning in Northern England, 1990-2002

Area of Science:

• Medical Imaging
• Public Health
• Socio-economic Determinants of Health

Background:

• Socio-economic status significantly impacts lifelong health outcomes.
• Childhood studies reveal higher injury rates in deprived environments.
• This suggests a potential link between socio-economic status and medical imaging procedures like CT scans.

Purpose of the Study:

• To investigate socio-economic disparities in computed tomography (CT) scan utilization among young individuals.
• To analyze variations in CT scan rates based on deprivation levels in Northern England from 1990 to 2002.

Main Methods:

• Utilized electronic data from Radiology Information Systems across nine NHS hospital Trusts.
• Linked CT scan data (sex, age, scan type, number) with Townsend deprivation scores derived from census data.
• Employed chi-squared tests and Spearman rank correlations to assess associations.

Main Results:

• Over 39,000 scans on 21,000 patients were analyzed, with over 38,000 scans linkable to deprivation data.
• Significant differences (p < 0.0001) were found in scan and patient distributions across deprivation quintiles.
• Deprivation correlated with scan types (more head scans in deprived areas) and patient age (younger children in more deprived groups).

Conclusions:

• Social inequalities are evident in CT scan usage among young people.
• Individuals from more deprived areas are more likely to undergo CT scans.
• This disparity may reflect higher injury rates and could result in differential radiation exposure within the population.
