»
»
Fill out as many questionnaires as possible
~ Demographics, CAGE and Compton/Jameson Questionnaires
I-S.O.A.P., C.M.S.D., P.B.Q., PDQ-4+, C.S.Q.,
C.P.S.S., S.E.F., S.E.O.S., STAI, and BDI-II
Subject given contact information
» Advised of a F/U appointment with the psychologist
~ Scheduled within 14 days after the ED visit
•
•
Subject contacted within one week of ED Visit to schedule a F/U visit with psychologist
»
»
If all questionnaires are not complete
~ Opportunity at time of F/U visit to complete all questionnaires
The patient will meet with the psychologist for the
S.C.I.D.
» After meeting with the psychologist, the patient is informed about payment for participation
Completed Subject
» A set of complete questionnaires, BDI-II, and S.C.I.D. evaluation
•
•
Ability to view the ED “Whiteboard” via remote computer in our
Academic Offices enables remote screening
» Research Assistants can utilize computers to look for patients who complain of the following generalized symptoms:
~ Chronic or Mild Stable Pain
~ Chronic Back Pain
~ Headache
~ Earache
~ Rx Refill Request
~ Diffuse Body Pain
~ Vague Abdominal Pain
Students travel to the ED to recruit these identified subjects
•
•
Students within the ED have significant access
»
Electronic “Whiteboard”, patient charts, and physical
“Whiteboard”
» Patients recruited using the inclusion/exclusion criteria designated by the protocol
Students approach patients within different Areas, including the waiting room, where they will proceed through the following steps:
»
»
»
»
Brief introduction to the study
Informed Consent
Administration of Study Questionnaires
Collection of all study materials before student and/or patient departs from the ED
• A Research Assistant will contact subject via telephone within 1 week of the initial ED visit
» At this time, the subject is scheduled to complete
Visit 2 within 14 days of the initial ED visit
» The subject is contacted by telephone up to three times before the patient will be discontinued due to lack of compliance

Successful Strategies and Barriers
• Useful Recruitment Strategies
~
Presence of recruiter in the ED between the hours of 11am-8pm
M-F (five day coverage to maximize patient recruitment)
~ Patient completion of BDI-II along with as many questionnaires as possible within the ED
• Barriers to Recruitment
~
2 nd Visit does not receive as much of a response from patients
~ 2 nd visit can only be completed on Fridays
~ Excluding patients who arrive by ambulance: Some chronic pain patients, utilize the ambulance to “get a ride” to the
ED.
~ 14 day interval between visits is too small
• Questionnaire for
Patients &
Providers
» Same questions
~ Framed differently
•
• Patient
I do not have adequate time to assess and treat
ED patients complaining of chronic pain
•
• Provider
Doctors and nurses avoid spending enough time to talk about your chronic pain

(like seeing injured people or those with heart attacks)

X-ray, they tend not to believe you could be in pain

~ No opioid contracting
