Pilot randomized controlled trial of a hypnosis intervention for women with bladder pain syndrome.

ABSTRACT

AIMS: To evaluate the feasibility and acceptability of a randomized controlled trial of a hypnosis intervention for the treatment of bladder pain syndrome/interstitial cystitis (BPS/IC) in women. METHODS: We conducted a parallel arm, non-blinded, pilot randomized controlled trial of standardized hypnosis sessions including a hypnosis web tool versus usual care in adult women with BPS/IC. Pilot study outcomes included feasibility domains process, resources and management, safety, and acceptability. Clinical outcomes of lower urinary tract symptoms and quality of life were measured using validated questionnaires at baseline and at the end of the 4-week intervention. RESULTS: We randomized 29 out of 30 (96.7%) eligible women. In the hypnosis group, 12 of 15 (80.0%) subjects completed the 4-week intervention and follow up, and 13 of 14 (92.9%) in the usual care group. In the hypnosis group, adherence to the standardized sessions was 80% and participants used the web-based tool for an average of 5.6 ± 2.7 times per week. Scores for emotional distress, relaxation, pain severity and expected bladder symptoms significantly improved during the first two of three planned hypnosis sessions (all p < 0.05). Improvement in quality of life scores was greater in the hypnosis group than the usual care group (-2.6 ± 2.3 vs. -0.9 ± 1.1, p = 0.04). There were no significant between-group differences in urinary symptoms or bladder pain. No adverse events were reported. CONCLUSIONS: A hypnosis intervention for the treatment of bladder pain syndrome/interstitial cystitis is feasible, acceptable, safe, and may improve quality of life.
