POS0361-PARE THE MEDIATING EFFECT OF PAIN CATASTROPHIZING ON WORK PRODUCTIVITY

Abstract

BackgroundWork disability is a major patient outcome for spondyloarthritis (SpA) patients since SpA mostly appears in younger adults.Objectiveswe examined the influence of catastrophizing as a negative psychological factor on work productivity and activity impairment in SpA.MethodsWe conducted a cross-sectional study over a 3 months period. We included patients treated with SpA (Assessment of SpondyloArthritis International Society (ASAS) 2009 criteria). Patients related data, and disease characteristics were collected. Pain catastrophizing were assessed by the pain catastrophizing score (PCS). Work productivity and activity impairment were evaluated by Work productivity and Activity Impairment Questionnaire (WPAI). WPAI score examined four aspects of the patient’s life: Absenteeism due to SpA and presenteism at work, work productivity loss and activity impairment.ResultsSixteen SpA patients were enrolled (22 females and 38 males). Mean age was 39,4 years ± 11,08. Mean disease duration was 11,37 years ±7,23; 28 were unemployed. Among workers, absenteeism due to SpA was reported in 7 cases (21,9%). Mean absenteeism rate was 2,35% [0-20]. Both mean work productivity loss and mean activity impairment were 50,23% [20-90].Mean PCS was 15,73 ± 13,893. Thirteen patients (21,7%) had PCS >30 which indicates a clinically relevant level of catastrophizing, and only two of them reported absenteeism at work. PCS score was higher in patients with absenteeism (mean score=26), compared to patients without absenteeism (mean score=16,96), (p=0,166). Presenteeism was lower in patients with higher pain catastrophizing scores, without reaching a significant difference (p=0,066). A higher PCS was significantly correlated with a greater work productivity loss (p= 0,036, r=0,371) and greater activity impairment (p=0,005, r=0,36).ConclusionIn our series, pain catastrophizing affected work productivity and daily activity in patients with SpA.Disclosure of InterestsNone declared
