Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Adults aged 18 or older, diagnosed with FI as indicated per commercially available IFU.

Description

Inclusion Criteria:

  1. 18 years or older
  2. Primary indication of Fecal Incontinence (FI)
  3. Willing and capable to provide informed consent and agrees to comply with specified evaluations at selected clinical centers

Exclusion Criteria:

  1. Any significant medical condition that is likely to interfere with study procedures, device operation, or likely to confound evaluation of study endpoints (includes neurological conditions such as multiple sclerosis)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Performance/effectiveness - Improvement in Quality of Life scoring (FI)
Time Frame: 3 months
Short-term FI improvement demonstrated by Cleveland Clinic Florida Fecal Incontinence Score (CCF-FIS). Cleveland Clinic Florida - Fecal Incontinence Score (CCF-FIS): scores range from 0 for full continence to 20 for complete incontinence. A higher score is indicative of the severity of fecal incontinence.
3 months
Performance/effectiveness - Improvement in patient satisfaction scoring (FI)
Time Frame: 3 months
Short-term FI improvement demonstrated by Participant Satisfaction with Treatment and Charging Questionnaire. Participants will indicate satisfaction with SNM therapy for treatment of their FI symptoms based on a 7-point Likert scale ranging from "Very satisfied" to "Very dissatisfied".
3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Performance/effectiveness - Improvement in patient satisfaction scoring (FI)
Time Frame: 12 months
Participant Satisfaction with Treatment and Charging Questionnaire at 1-year post-implant compared to baseline. Participants will indicate satisfaction with SNM therapy for treatment of their FI symptoms based on a 7-point Likert scale ranging from "Very satisfied" to "Very dissatisfied".
12 months
Performance/effectiveness - Improvement in Quality of Life scoring (FI)
Time Frame: 12 months
Demonstrate any improvement in CCF-FIS at 1-year post-implant compared to baseline. Cleveland Clinic Florida - Fecal Incontinence Score (CCF-FIS): scores range from 0 for full continence to 20 for complete incontinence. A higher score is indicative of the severity of fecal incontinence.
12 months
Performance/effectiveness - Improvement in Quality of Life scoring (FI)
Time Frame: 3 months, 12 months
Demonstrate an improvement in Fecal Incontinence Quality of Life (FIQOL) at 3 months, and 1-year post-implant compared to baseline. Fecal Incontinence Quality of Life (FIQOL) includes four different subscales: lifestyle, coping/behavior, depression/self-perception and embarrassment. Subscale scores range from 1 to 5, with 1 indicating lower functional status of qualify of life.
3 months, 12 months
Adverse event reporting (Safety)
Time Frame: 3 months, 12 months
Device related, procedure-related and all serious adverse events
3 months, 12 months

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
