- Background: Although direct medical costs for constipation-related medical visits are thought to be high, to date, there have been no studies examining longitudinal resource utilisation in adults with constipation.
Aim: To estimate the incremental direct medical costs associated with constipation in women.
Methods: This is a nested case-control study. The study population consisted of all mothers of 5718 children in the population-based birth cohort born during 1976-1982 in a community. The cases presented to the medical facilities with constipation. The controls were randomly selected and matched to cases in a 2:1 ratio. Direct medical costs for constipated women and controls were collected for the years 1987-2002.
Results: We identified 168 women with a diagnosis of constipation. The total direct medical costs over the 15-year period for constipated subjects were more than double those of controls [$63 591 (95% CI: 49 786-81 396) vs. $24 529 (95% CI: 20 667-29 260)]. The overall out-patient costs for constipated women were $38 897 (95% CI: 31 381-48 253) compared to $15 110 (95% CI: 12 904-17 781) for controls. The median of annual out-patient visits for constipated women was 0.16 compared to 0.11 for controls.
Conclusion: Women with constipation have significantly higher medical care utilisation and expenditures compared with women without constipation.
