# Using Patients' Social Contact to Improve Out-Patient Endoscopy Among Blacks

**Official Title:** Improving Attendance to Outpatient Endoscopy Among Blacks

**NCT ID:** [NCT02464618](https://clinicaltrials.gov/study/NCT02464618)

## Key Facts

- **Status:** COMPLETED
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 812
- **Lead Sponsor:** Howard University
- **Conditions:** Compliance, Colon Cancer
- **Start Date:** 2014-06-26
- **Completion Date:** 2017-03-07
- **CT.gov Last Update:** 2018-09-17

## Brief Summary

Non-attendance to out-patient endoscopic procedures is high among underserved blacks. The overall goal of this proposal is to evaluate the effect of directly involving a social contact (chosen by the patient) on completion and quality of out-patient endoscopy recommended for the patient by his/her primary care physician, or after scheduling by the gastrointestinal endoscopist.

Improved adherence and better quality of procedures are postulated with involvement of social contacts.

## Detailed Description

The overarching goal of this proposal is to determine whether directly involving a social contact, chosen by the patient, will improve the completion and quality of scheduled out-patient endoscopy among blacks.

These are three sub-projects:

Project 1: Involves recruiting 400 patients referred for colonoscopy by their primary care physicians

Project 2: Involves recruiting 400 patients scheduled for colonoscopy by their endoscopist

Project 3: Involves recruiting 200 patients scheduled for upper endoscopy by their endoscopists

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* Patients referred for out-patient colonoscopy by primary care physicians
* Patients scheduled for out-patient screening colonoscopy
* Patients scheduled for out-patient upper endoscopy

Exclusion Criteria:

* Patients who were referred for colorectal cancer (CRC) screening as in-patients
* Patients with personal history of familial adenomatous polyposis syndrome (FAP)
* Patients with family history of Hereditary non-polyposis colorectal cancer syndrome (HNPCC)
* Patients with inflammatory bowel disease
* Patients with Crohn's disease
* Patients with ulcerative colitis
* Patients with personal history of CRC
* Patients who have had colonic resection
```

## Arms

- **Usual care** (NO_INTERVENTION) — The social contact of patients in this arm will not be contacted
- **Social contact intervention** (ACTIVE_COMPARATOR) — The social contact of patients in this arm will be contacted and asked to facilitate the endoscopy care plan of the patient

## Interventions

- **Social contact intervention** (BEHAVIORAL) — The social contact of the patients in this arm will be engaged to improve adherence to out-patient endoscopy

## Primary Outcomes

- **Compliance with appointment and colonoscopy** _(time frame: 6 months)_ — For primary care subjects: Making appointment with Gastrointestinal endoscopist within 3 months and completing colonoscopy within 6 months of enrolment
- **Compliance with scheduled upper endoscopy and colonoscopy** _(time frame: Scheduled procedure time, an average of 8 weeks)_ — For specialty subjects: Completing scheduled upper endoscopy or colonoscopy

## Secondary Outcomes

- **Bowel preparation quality** _(time frame: At scheduled colonoscopy, an average of 8 weeks)_
