Rotator Cuff Surgical Outcomes in Women (RCSOW)

April 25, 2019 updated by: Marlis Sabo, University of Calgary
The overall purpose of this work is to use a prospective cohort study to examine patient-specific but shoulder-extrinsic factors and how they influence the results of rotator cuff surgery. There are undoubtedly many factors that play a role in patient outcome, however, this project will focus on three: the effect of gender on outcome, the effect of mood disorders and coping style on outcome, and the effect of patient height and reach on outcome after rotator cuff surgery. It is hypothesized that these factors will have a significant influence over outcomes.

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

35 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

The participants for this study will be selected from the practice of three shoulder reconstruction surgeons in their embedded clinical research practice.

Description

Inclusion Criteria:

  • Referred for surgical treatment of predominantly unilateral rotator cuff syndrome

Exclusion Criteria:

  • unable to speak or read English
  • unable to complete 12 month follow-up
  • significant cervicogenic arm and shoulder pain in the affected arm
  • significant chronic pain diagnoses felt at least as likely to be the cause of the symptoms as the rotator cuff condition as evaluated by the surgeon

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.

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
Western Ontario Rotator Cuff score (WORC)
Time Frame: 1 year
WORC scores will be compared at 12 months between the groups (males versus females)
1 year

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
Overall change in WORC (male versus female)
Time Frame: 1 year
Evaluation of the overall change in WORC score by gender

Primary Completion (Anticipated)

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. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
