This paper presents the development of a Graphical User Interface (GUI)
for calculating the sum of nail-fold (NF) and distal interphalangeal joint
(DIP) ratios for all ten fingers. The sum of NF:DIP ratios for all ten fingers
leads to the Digital Index (DI) that was used as the measure for identifying
and determining the presence of finger clubbing symptom. This GUI system
was developed to serve as a simple and user-friendly interface for clinicians
to calculate DI value of patients in a busy clinic practice. It is also equipped
with the capability to keep the patient’s past diagnosis medical check-up
data for future monitoring purposes. The result shows that the developed
system helps the clinicians to perform calculation of DI value and identify
the presence of finger clubbing in a very short time. The average time taken
to measure both NF and DIP circumferences using Finger Clubbing Meter,
and to compute DI values using Digital Index Evaluation System (DIES)
interface is 6:36 ± 1:24 minutes (Mean ± SD) .This system is expected to
contribute in detecting the finger clubbing problem at early stage of so the
treatment can be performed immediately.
