[Quality of life and its association with the severity of fecal incontinence].

Background: Wexner's score is widely used to assess the severity of fecal incontinence (FI). The 36-item short form health survey (SF-36) and the Fecal Incontinence Quality of Life Scale (FIQLS), a disease-specific scale, are instruments measuring quality of life that have been validated into Spanish.

Aim: To evaluate quality of life in patients with FI by using the FIQL and SF-36 scales to correlate the results with the Wexner's score.

Methods: Wexner's score, SF-36 and FIQLS were completed by 73 patients. The cut-off point for severity, as previously published, was 9 (Wexner's score <9=mild FI; Wexner's score ≥9=severe FI).

Results: the scores for all SF-36 sub-scales were lower in patients with FI than in the healthy Spanish population (p<0.001). The mental component of the SF-36 correlated with the subscales of «behavior» and «embarrassment» of the FIQLS (p<0.05). Wexner's score correlated with all the domains of the FIQLS (p<0.01). The results for all the domains of the FIQLS were lower for the Wexner ≥ 9 group than for the Wexner <9 group (p<0.001). There was no significant correlation between Wexner's score and the SF-36. Age, urge and daily FI, comorbidity and anorectal surgery worsened different aspects of quality of life measured by the FIQLS.

Conclusions: quality of life measured by the SF-36 and FIQLS was substantially impaired in patients with FI. The severity of FI correlated with FIQLS. Other factors such as age, type and frequency of FI should be considered when evaluating quality of life.
