Intravitreal Injection Utilization Rates Across 47 Japanese Prefectures, FY2017 vs FY2022

Prefecture-level summary statistics for intravitreal injection utilization in Japan for fiscal years 2017 and 2022. The dataset includes crude rates, rates for the population aged 75 and over, and indirectly age-standardized rates across 47 prefectures. Author Yoshiaki Kabata published this 9.4 KB Excel file under a CC-BY-4.0 license on figshare in May 2026.

Use Cases

• Analyzing geographic variation in medical procedure adoption based on prefecture-level utilization rates.
• Comparing changes in healthcare utilization over time based on the FY2017 and FY2022 data points.
• Studying the impact of population aging on healthcare demand based on rates segmented for the ≥75-year population.
• Benchmarking regional healthcare performance using standardized metrics like the coefficient of variation.

Strengths

• Provides a direct comparison between two time points (FY2017 and FY2022) for longitudinal analysis.
• Includes multiple standardized metrics (mean, SD, min, max, ratio, CV) for robust statistical comparison.
• Covers the complete geographic unit of Japan with data for all 47 prefectures.

Limitations

• Row count and individual prefecture data are unknown; the dataset contains only summary statistics.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 9.4 KB file size indicates a very limited dataset containing only aggregated summary figures.
