241PROMs for Mobility
Mobility Scale
The Sollerman hand function test measures hand mobility. The scale has a score of
0–4 for each task performed with the total score out of 80 (higher score = full hand
function). Other mobility measures are fi ngertip to palm (FTP) distance and grip
strength. The serum urate concentrations correlated with the Sollerman score (cor-
relation coeffi cient: −0.59) as well as arthritis severity measures such as pain visual
analog scale, tender joint, and radiographic damage (correlation coeffi cient ranging
from −0.71 to −0.67) [ 45 ].
PROMs for Satisfaction
Patient Satisfaction
Patient satisfaction is an important PRO. Patients with more comorbidities (cases)
were more likely to have poor satisfaction with their health compared to those who
did not (controls) (mean satisfaction with health; cases mean: 13.16; control mean:
14.45) [ 60 ], providing some evidence for construct validity.
PROMs for Global Disease Severity
Patient Global Disease Severity Score
The scores range from very well (score of 0) to very poor (score of 100). In patients
with gout, patient global VAS scores had low correlations with domains such as
tender and swollen joints, moderate correlations with SF-36 and HAQ scores, and
no correlation with plasma urate levels, disease duration, recent gout fl ares, or
comorbidities [ 7 ].
PROMs for Health Utility
Data on health utilities is limited due to their inclusion in only a few studies. Studies
show a lower score in patients with gout compared to the general population, indi-
cating their construct validity.
