Area of Science:

  • Medical diagnostics
  • Morphometry
  • Pulmonary medicine

Background:

  • Finger clubbing is a physical sign associated with various underlying diseases.
  • Early-stage finger clubbing lacks sufficient research and standardized measurement techniques.
  • Accurate quantification is needed to track disease progression or regression.

Purpose of the Study:

  • To establish the Digital Index in healthy subjects.
  • To assess the time and interrater reliability of the Digital Index measurement.
  • To highlight the need for efficient tools like the Digital Index Quantitator (DIQ).

Main Methods:

  • Utilized thread and manual Vernier calipers to determine the Digital Index.
  • Measured the time required for the procedure.
  • Assessed interrater reliability using Pearson's correlation coefficient.

Main Results:

  • The mean Digital Index in healthy subjects was 8.86 ± 0.29 (range: 8.15–9.41).
  • Interrater reliability was excellent (Pearson's r = 0.966).
  • Measurement time averaged 35.97 ± 9.16 minutes, with a range of 21.93–68.80 minutes.

Conclusions:

  • The Digital Index is a reliable metric for healthy individuals.
  • Manual measurement is time-consuming, suggesting the need for automated tools.
  • The Digital Index Quantitator (DIQ) offers potential for efficient and accurate quantification of digital clubbing.
