Hypnotherapy for Treatment of Overactive Bladder

Overactive Bladder Clinical Trial

Official title: Hypnotherapy for Treatment of Overactive Bladder: A Feasibility Study

Status Completed

Clinical Trial Summary

The investigators purpose is to perform a pilot study evaluating the efficacy in hypnotherapy in treating women with Overactive Bladder Symptoms (urinary urgency symptoms and urinary frequency). Approximately half the women in the study will receive "standard care" (performing a voiding diary, Pelvic Floor exercises, and timed voiding) and the other half will receive "standard care" and 3 hypnotherapy sessions. The investigators will compare the groups using a validated overactive bladder questionnaire and compare voiding diaries to evaluate urinary frequency at the end of the sessions/study completion.

Clinical Trial Description

Experimental Design and Methods:

i) This is a feasibility study (prior to performing a larger randomized controlled trial at a later date) evaluating whether hypnotherapy effectively treats Overactive Bladder (OAB). Ultimately, for the larger study, in order to find a 20% difference between the hypnotherapy group and controls, we will need to evaluate a total of approximately 66-70 women to find a 20% difference between groups, assuming 80% power and P=0.05. However, the purpose of this pilot study is to evaluate the feasibility of the larger study and determine the appropriate control intervention and outcomes. We plan to evaluate approximately ten subjects (approximately twenty overall) in both the control and hypnotherapy groups.

ii) Patients OAB will be offered entry into the study. a) Inclusion criteria: women experiencing 8 voids/day and an OAB Awareness tool score greater than 8. b) Exclusion criteria: males (since we do not care for males in the gynecology clinic), non-English speakers, pregnant women, women younger than 18 years old, incarcerated women, women with a history of bipolar disorder or schizophrenia, women unwilling to undergo hypnotherapy iii) Informed consent will be obtained. iv) Prior to receiving interventions, patients will be administered the OAB-q & instructed to keep a 3 day voiding diary. If the patient has not had a pelvic exam in the urogynecology clinic within the last year, a pelvic exam will be performed.

v) The usual standard treatments for OAB include pelvic floor exercise, voiding diaries, bladder drills (increasing time between voids), and anti-cholinergic medications. The control group will be offered any or all of our standard treatments, including Behavioral treatment (review of voiding diaries and instruction regarding behavioral changes). Both groups will be allowed to continue current OAB medications but asked not to start new medications. The hypnotherapy group will also be offered any or all of our standard treatments, but they will be given the option of receiving hypnotherapy in addition to the usual treatments.

vi) Hypnotherapy sessions: Dr. Sapien will conduct 3 hypnotherapy session to women randomized to the hypnotherapy group. These sessions will occur approximately every1-2 weeks over approximately a time span of 6-8 weeks. The sessions will last 60-90 minutes. Session #1) Explain hypnotherapy and practice suggestion therapy; Session #2) address emotions around OAB and life impact, visualization of pelvic floor exercise mechanics, teach self hypnosis; Session #3) address emotions, further practice on exercises and self-hypnosis vii) Blinding of Investigators and Allocation Concealment: Randomization will be performed by the CTSC using computer generated allocation. Only the CTSC personnel will know the assignment schema. Researchers will not know the group assignments. A research nurse otherwise uninvolved in the study will place the group assignments in serially numbered, opaque envelopes. Once subjects sign consents they will receive an opaque envelop assigning them to the Behavioral Therapy or Hypnotherapy group. The individual responsible for data collection and data entry will not know the group assignment until the end of the study when the assignment code is broken.

VI. Human Subjects:

i) See inclusion & exclusion criteria described previously. Children, prisoners and mentally ill or disabled subjects will be excluded from our study. Women who are pre-menopausal and who are not using contraception and have missed a menstrual period will be offered a pregnancy test in the clinic, as is the standard of care in the gynecology clinic. Pregnancy is an exclusion criteria for study participation.Women evaluated in the Gynecology Clinic at the University of New Mexico will be offered participation in the study.

ii) Women will be offered study participation in a private setting at their gynecology visit if have the symptoms of OAB noted previously (V.ii).The study will be described verbally and they will receive a copy of the consent form to read. They will be given the option of taking the consent home to have time to consider whether they would like to participate. If the patient wishes more time to consider whether she would like to participate, she will be asked whether she would agree to phone follow-up by a study investigator. If she agrees, she will have phone follow-up at least 24 hours after her clinic visit. If the patient expresses interest in participating in the study, she will then return to sign her consent with a study investigator. All patients will be reassured that declining study participation will have no effect on the care that they receive iii) Potential Risks of Hypnotherapy: Potential Risks of Hypnotherapy: Risks of hypnotherapy are minimal. Hypnosis is a natural state of mind in which the subconscious is accessed and utilized to make a positive impact. Although, in the 1980 false memory syndrome was described with the use of hypnotherapy in child abuse survivors, the current practice of hypnotherapy uses a much different approach to this therapeutic application. Current practice includes open-ended lines of questioning as opposed to suggestive or leading lines of questioning utilized with these victims.

Risks will be minimized by using open-ended lines of questioning for all hypnotherapy sessions (see above). For this study the hypnotherapist is also a physician, therefore physician-patient confidentiality guidelines are in place. Subjects will be asked to contact the PI if they believe that they are suffering from a psychological burden which has occurred from their involvement in the study.

It is highly unlikely that this study would be terminated, as the risks to participants are minimal. However, in the unlikely circumstance that a large number of hypnotherapy subjects complain of severe psychologic or physical discomfort with their hypnotherapy sessions (despite incorporation of relaxation techniques in the sessions), the study would be terminated. Subject case discussion will be conducted by the research team in a private setting

Potential Risks to Control Group: The control group will be offered standard care for treatment of OAB and will not be exposed to any greater risk than usual for OAB treatments iv) Potential Benefits of Hypnotherapy: Alleviating or diminishing symptoms of frequent urinary, urinary urgency and urine leakage.

v)Safety Oversite: The investigators will meet approximately monthly to review study progress and subject issues/complaints. The subjects will have follow-up with either phone or in-person contact with the hypnotherapist or CTSC personnel. If major events, though unlikely, occur, they will be reviewed with appropriate CTSC and HRRC personnel.

vi) After the study is finished, the patients in the control group have the option of undergoing an approx. 20 minute relaxation hypnotherapy session with Dr. Sapien. ;
