Background:

BASDAI, BASFI, and other instruments used to evaluate Ankylosing Spondylitis (AS) patients are usually self-administered on paper. However, it limits their use in daily clinical practice because paper forms are resource demanding regarding the time spending for filling them. A phone administration previously to the medical visit it would facilitate the use of these tools.

Objective:

to assess the performance of the instruments used to evaluate AS patients when administered by phone in comparison with the traditional self-administration on paper.

Methods:

Design: a test-retest study. Patients with AS (modified NY criteria) consecutively selected in a tertiary care center were included. Patient global assessment on numerical rating scale (NRS), patient global pain assessment on a NRS, patient night pain assessment on a NRS, BASDAI, BASFI, and ASQoL were administered by phone. 48 later the same instruments were self-administered on paper at the hospital. Descriptive statistics were done. Agreement between the two tests was assessed by the intraclass correlation coefficient. Spearman correlation coefficient was also calculated.

Results:

51 patients, 76% males, with age 47.7±13 years were included. The time between phone administration and self-administration on paper was 1.5±1.0 days. Mean±SD values of the instruments obtained by phone administration and self-administration on paper, intraclass correlation coefficients (ICC) and Spearman correlation coefficients (rho) were as follows: patient global assessment on a NRS: 3.8±2.8, and 3.8±2.4, ICC: 0.80*, and rho: 0.80*; patient global pain assessment on a NRS: 3.9±2.9, and 3.7±3.0, ICC: 0.89*, and rho 0.82*; patient night pain assessment on a NRS: 3.6±3.0, and 3.4±3.0, ICC: 0.90*, and rho: 0.87*; BASDAI: 3.9±2.6, and 3.5±2.5, ICC: 0.91*, and rho: 0.92*; BASFI: 3.6±2.7, and 3.5±2.7, ICC: 0.91*, and rho: 0.92*; and ASQoL: 6.2±5.3, and 6.1±4.9, ICC: 0.93*, and rho: 0.87*, respectively. *p<0.001.

Conclusions:

the phone administration of these instruments is comparable to their self-administration on paper. It can facilitate their use in daily clinical practice.
