Randomized Controlled Trial Comparative Study Clinical TrialA comparison of the Hopkins Pain Rating Instrument with standard visual analogue and verbal descriptor scales in patients with cancer pain.
A self-contained, portable, pain rating instrument that provides an immediate result for documentation purposes was developed to improve pain assessment in cancer patients. The Hopkins Pain Rating Instrument (HPRI) is a 5 x 20 cm plastic visual analogue scale (VAS) with a sliding marker that moves within a groove that measures 10 cm. The side facing the patient resembles a traditional VAS while the opposite side is marked in cm to quantify pain intensity. ⋯ The most common pain sites were the back, leg, and epigastric areas. On initial and repeat testing, there were high correlations between the HPRI and the VAS (r = 0.99, P less than 0.0001) and the VDS (r = 0.85, P less than 0.0001). The correlation coefficients for test--retest reliability for the HPRI, VAS, and VDS were 0.97, 0.97, and 0.94 (P less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
