Constipation severity is associated with productivity losses and healthcare utilization in patients with chronic constipation

subject

description

OBJECTIVE: We sought to evaluate the association between constipation severity, productivity losses and healthcare utilization in a national sample of Italian patients with chronic non-organic constipation (CC). METHODS: We enrolled 878 outpatients with CC. Clinical and demographic data were collected by physicians during clinical examinations. Patients completed a self-administered questionnaire (Patient Assessment of Constipation-Symptoms, PAC-SYM; Work Productivity and Activity Impairment; healthcare utilization, and Symptoms Checklist 90 Revised - Somatization Scale, SCL-90 R). RESULTS: Mean PAC-SYM score was 1.62 ± 0.69. Mean weekly sick time due to constipation was 2.7 ± 8.6 h and productivity losses due to presenteeism was 19.7% ± 22.3%. Adjusted productivity losses in patients with severe CC (PAC-SYM score 2.3-4.0) compared to patients with mild symptoms (PAC-SYM score 0.0-1.0) was Italian Purchase Power Parity US$ 6160. Constipation severity (PAC-SYM quintiles) was associated with higher healthcare utilization (RRPAC-SYM 4/01.84; p-value for linear trend <0.01). After adjustment for somatization scores, the association of constipation severity with productivity losses and healthcare utilization rates was attenuated yet statistically significant. CONCLUSIONS: We observed a graded increase in productivity losses and healthcare utilization with increasing constipation severity. Further studies should evaluate whether significant savings might be achieved with regimens aimed at reducing the constipation severity.
