Systemic sclerosis & Raynaud's

Comparison of Three Physician Global Assessment Instruments in Systemic Sclerosis

Arthritis Care Res (Hoboken)Published Cohort study

Authors' conclusion

PhyGAs of overall health, activity, and damage are each associated with different SSc features, and changes in different PhyGA scores are discordant 50% of the time.

Study context

Population
Participants of the Australian Scleroderma Cohort Study (Systemic Sclerosis (SSc))
Participants
1,965 Australian Scleroderma Cohort Study (ASCS) participants
Exposure
Three PhyGA instruments: overall health vs activity vs damage
Outcome
Comparability (correlation and concordance of change between study visits) of three PhyGA instruments
Methodological detailsordered logistic regression
  • Ordered logistic regression

Main finding

As reported in the abstract

Comparability of PhyGA instruments

Concordant changes of PhyGA scores between study visits

50%

Observational data: associations, not effects.

Further findings

Patient-reported breathlessness associated with PhyGA scores

Overall health: OR 1.67, P < 0.01
Activity: OR 1.44, P < 0.01
Damage: OR 1.32, P < 0.01
  • Only feature associated with all three PhyGA scores

Associations with changes in activity scores

Patient-reported worsening skin disease: OR 1.25, P = 0.03
Fecal incontinence: OR 1.23, P = 0.01

Associations with damage scores

PAH: OR 1.25, P = 0.03
Chronic obstructive pulmonary disease: OR 1.37, P = 0.04
Skin scores: OR 1.02, P < 0.01
Fecal incontinence: OR 1.21, P = 0.02
