Chapter 6: Baseline Examination Visit Version 5.0 10/17/08 Page 6-2 XACT Manual of Procedures Chapter 6: Baseline Examination Visit The baseline examination visit is the second face-to-face meeting with a study participant. At this visit the experiences of the run-in period are reviewed and discussed. A final decision is made by both the participant and the Study Coordinator regarding participation for the duration of the study. If the decision is to participate, the baseline clinical examination is performed, the participant is randomized, and the intervention is initiated. A. Purpose The purposes of the baseline examination visit are to: 1. Assess run-in period adherence and experiences 2. Assess participant side effects related to mint use 3. Review Enrollment Medical History information 4. Evaluate presence or absence of Serious Adverse Events 5. Confirm Eligibility and enter into DEMS 6. Perform the baseline oral examination 7. Perform randomization 8. Obtain Baseline Questionnaire information 9. Schedule Intervention Follow-up Call 10. Review Participant Contact Form 11. Dispense initial supply of intervention mints and review Intervention Information Sheet 12. Reimburse participant 13. Enter remainder of data into the DEMS 14. Place examination findings in institutional record, if applicable B. Personnel Study Coordinator (SC) Dental Examiner Recorder C. Setting The baseline enrollment visit occurs in the clinical center. It is a visit led by the Study Coordinator and scheduled for a period when the Examiner and Recorder will be available (see MOP Chapter 4, Enrollment Visit, E.8). The visit is scheduled to last approximately one hour. A private office and/or clinical operatory is used. D. Preparation for the Baseline Examination Visit The SC or other study personnel reminds the enrollee of the baseline examination appointment during the reminder call (see Chapter 5, Run-In Period, Section E). The SC (or other study personnel) mails the Baseline Questionnaire a week before the scheduled visit (see Chapter 5, Run-In Period, Section F) if the Questionnaire is being mailed. Sites also have the option of Chapter 6: Baseline Examination Visit Version 5.0 10/17/08 Page 6-3 XACT Manual of Procedures set aside time at the Baseline Visit to allow the participant to complete the questionnaire instead of mailing it in advance. The following materials are needed at the time of the baseline examination visit: Completed Adherence Assessment form from the Run-in Follow-up Call Patient clinical chart Baseline Questionnaire completed by participant or blank copy for participant to complete Completed Enrollment Medical History form Side Effects form Eligibility Confirmation form Serious Adverse Events form (if relevant) Baseline Oral Examination Recording form Baseline Visit Checklist Randomization form Early Termination form (if relevant) Stamped, addressed mailing pouch for return of unused mints from run-in period (if not returned during visit) Intervention Information Sheet Mint Dispensing Log Reimbursement Log In addition, the person conducting the Baseline Visit needs to have convenient access to a computer that can access the DEMS and access to the locked storage area for the mints. After the randomization ID number is obtained through the DEMS randomization process, s/he retrieves and dispenses the intervention mints with the corresponding randomization number. E. Conducting the Baseline Examination Visit Summary: Visit activities occur in the order listed in the “Purpose” section above. After reviewing the participant’s experiences and compliance during the run-in period, a joint participation decision is reached between the Study Coordinator and the potential participant. If the decision is made to have the participant continue, an oral examination is performed, followed by review of the completed Baseline Questionnaire. If the participant failed to bring in a completed Baseline Questionnaire, s/he is asked to complete it before the oral examination, so that all participants have these two experiences in the same order. The SC randomizes the participant using the DEMS immediately after the baseline examination. This requires entry of the Eligibility Confirmation form. Before departing, the participant is given an initial supply of intervention mints, instructions for their use, and an appointment for the Intervention Follow-up Call is made. E.1 Review Adherence The Study Coordinator and the participant discuss the run-in period experience. This conversation is guided by the Adherence Assessment form completed during the Run-in Call. The discussion focuses on the participant’s adherence and attitude toward the daily use requirement after 18-days of experience with it, and the participant’s commitment to attempting to maintain the regimen for the next three years. The enrollee is also instructed not to consume any additional mints from the run-in supply. Chapter 6: Baseline Examination Visit Version 5.0 10/17/08 Page 6-4 XACT Manual of Procedures If a participant cannot come in for their Baseline Visit within a week of the end of the Run-in period then the Adherence Assessment form for the Baseline Visit can be completed through a telephone call with the participant. This call must be conducted within the acceptable window for the Baseline Visit. E.2 Assess possible side effects related to mint use Complete the Side Effects form with the participant. During this process, the Study Coordinator may become aware of side effects that may be classified as Serious Adverse Events. If this occurs, further discussions about the side effect are warranted to determine if the event meets Serious Adverse Event criteria. If the event is serious, see section E.3 for information on how to proceed. E.3 Review completed Enrollment Medical History Form and Evaluate any possible SAEs The Study Coordinator reviews the completed Enrollment Medical History form with the participant. If anything has changed, record description and information about change in the participant’s progress notes. Once the review is complete, have the participant initial and date in the indicated fields at the end of the form. During the Enrollment Medical History review process, the Study Coordinator may learn about any possible events that may be considered Serious Adverse Events. If any incidents meet the criteria for a Serious Adverse Event, the SC completes the Serious Adverse Events form, and all notification procedures are followed (see MOP Chapter 15, Data and Safety Monitoring Follow-up may be required for ongoing SAEs, especially to assess relatedness, action, outcome, and resolution. Review the subject’s previous unresolved SAEs from previous contacts at this visit if relevant. E.4 Make the final enrollment decision Following the run-in adherence discussion, the Study Coordinator decides whether to offer the enrollee the opportunity to continue participation in the study. This decision is based on the SC’s assessment of the likelihood that the enrollee: Will continue to participate for the duration of the study Is entering the study with the intent to adhere to the regimen to the extent possible The participant must have consumed at least 38 or more mints in the Run-in period to be eligible for randomization. A participant who doesn’t meet the minimum threshold should not be randomized because they have not demonstrated adequate adherence to the mint schedule. The benefit of any doubt should be given to the enrollee. Perfect adherence is not a criterion for selection to participate. Rather, we wish to include participants with the intent to maintain good adherence. Imperfect adherence by some participants is expected and is part of the trial. Minimum adherence criteria for continuation are use of more than one-half of mints overall (38+ mints) during the 18-day run-in period, determined by self-report and confirmed by return of fewer than 38 mints. An enrollee who is offered the opportunity to participate is asked directly if he or she wants to continue in the study. With a negative response, probe gently and in a non-threatening manner for the reason for refusal. Best efforts should be made to illicit a very specific reason for early termination. The enrollee is thanked and excused. The reason for the enrollee’s response is then recorded on the Early Termination Form and an Randomization form is completed indicating that the participant was not randomized. For an enrollee who is not offered the opportunity to continue, the reason for not extending the offer is recorded on the Early Termination Form along with the indication that the participant was not randomized on the Randomization Form. The reason(s) for not extending an offer to continue in the study are explained in a neutral, non-punishing way to the enrollee. Chapter 6: Baseline Examination Visit Version 5.0 10/17/08 Page 6-5 XACT Manual of Procedures For a continuing participant, the Eligibility Confirmation form is completed to confirm eligibility status. If the SC concludes that the participant no longer meets eligibility requirements, the participant will be dismissed. The reason for non-randomization is recorded on the Early Termination form as ‘Participant Ineligible’ and a Randomization Form is completing indicating that the participant was not randomized. E.5 Perform the baseline oral examination The baseline oral examination is a detailed caries examination of the coronal and root surfaces of all teeth present. The Examiner does not have access to radiographs, treatment notes, treatment plans, or screening notes from the participant’s institutional chart. The details of the examination procedure and recording are presented in Chapter 13, Training and Monitoring. In brief, each coronal surface (occlusal, buccal, lingual, mesial and distal) and each exposed root surface (facial, lingual, mesial and distal) is examined for the presence of a caries lesion. The examination begins in the participant’s upper right quadrant with tooth #1, if present, and continues in numerical order through tooth #32. For each tooth space, the status of the tooth is recorded as present or missing. If present, each surface is scored for filling status, caries status and severity, and caries activity. The soft tissue examination consists of visual inspection of lips, buccal mucosa, gingiva, palate, oropharynx, tongue, and sublingual tissues. Surface status scores are called by the Examiner and recorded on the Oral Examination form by the Recorder. Both the Examiner and Recorder are appropriately trained before initiation of the project (see Chapter 13, Training and Monitoring). The Recorder prompts for all uncalled surfaces and requests clarification for all illogical calls. Once the examination is complete, both the Examiner and Recorder scan the examination form to verify that it is complete and that the required examiner, recorder, and participant ID numbers and the date are recorded on the form. The Recorder is responsible for returning the completed examination form to the Study Coordinator. E.6 Perform randomization The Study Coordinator randomizes the participant after the decision to continue participation has been made jointly by the Study Coordinator and the participant, and the baseline eligibility criteria have been reviewed with a favorable outcome. The SC performs randomization by entering the required information into the DEMS (MOP Chapter 19, Randomization). The DEMS will return the randomization assignment. The randomization report indicates date and time of the randomization and identifies the randomization ID number assigned to the participant. The randomization ID number is used to identify the mints to be dispensed to that participant. This randomization report is printed, initialed, and dated by the staff member completing the randomization and placed in the participant’s research chart. The SC must also complete and enter the randomization form after the actual randomization has been completed in the DEMS. E.7 Review/Complete Baseline Questionnaire If the participant is continuing in the study, the participant is asked to review the completed Baseline Questionnaire with the Study Coordinator. If the participant has not brought the completed form of if the site has opted not to mail the Questionnaire to the participant in advance of the visit, s/he is given a copy to complete at this time. The Study Coordinator then reviews the form, checking for non-responses, illogical responses, and any areas of uncertainty indicated by the participant. Each question is briefly inspected and the respondent queried about any inconsistent or incomplete responses (see Chapter 12, Data Management, for additional details on reviewing completed forms). If the participant left a copy at home, ask the participant to discard it rather than sending it in later. E.8 Schedule phone contact for the initial intervention period Review the Intervention Information Sheet, reminding the participant that he or she will be contacted by telephone two weeks into the intervention. Chapter 6: Baseline Examination Visit Version 5.0 10/17/08 Page 6-6 XACT Manual of Procedures Explain that the purposes of this call are to: Assess how closely the participant has been able to follow the dosage schedule Capture any side effects or other reactions to the mints that might be experienced Agree on a time when the participant is likely to be available and record the date and time for the call on the participant’s copy of the Intervention Information Sheet. Record the information on a second copy of the Intervention Information Sheet for placement in the participant’s consent folder. In a process similar to that used during the enrollment visit for the run-in period, schedule the call in the presence of the participant to reinforce the idea that this is an agreed-upon “appointment” for checking on the participant’s progress. Confirm that the participant will be expecting this contact, so that it is not perceived as intrusive. Enter the scheduled call date and time into the contact reminder screen in the DEMS. Inform the participant that there will be routine re-supply telephone checks scheduled at quarterly intervals and an annual visit around their first year anniversary. E.9 Update Contact Information Form Review with the participant. If any information has changed, update the form following proper data correction procedures. E.10 Dispense initial supply of mints The SC will dispense an initial supply of the intervention mints labeled with the randomization ID number that corresponds to the randomization ID number assigned to the participant by the DEMS. The mints are dispensed to the participant in bottles of 75 mints per bottle. The participant is given a total of 7 bottles for the initial dispensing. The participant is also given a carrying tin that will hold a few days’ worth of mints and written instructions for their use. The participant is informed that re-supply during the first year is accomplished by mail and will be accompanied by telephonic adherence assessment and encouragement. The Study Coordinator reviews the daily usage requirements with the participant, including the number of mints to be consumed during the current day: Visit time Up to 12 noon After 12 noon # of mints on Day 1 2 1 The SC also reviews the mint schedule for the start-up period: Study day # of mints/day 2-3 4-6 7-9 10+ 2 3 4 5 The SC also confirms the desired telephone number and time of day for follow-up contacts. The address for re-supply mailings is also confirmed at this time. An address usable by the USPS or other traceable mail shipper is necessary. All of this information is found on the Contact Information form, which was completed at the enrollment visit and updated as necessary. The dispensing is recorded on the Mint Dispensing Log. E.11 Provide participation payment The participant is given a participation payment for the Baseline examination. The participant signs a receipt for the check or other form of payment. The Study Coordinator records the participant’s payment in the Reimbursement Log, which is stored in the Subject Consent Chart together with the signed receipt. Chapter 6: Baseline Examination Visit Version 5.0 10/17/08 Page 6-7 XACT Manual of Procedures E.12 Dismiss participant After confirmation of the initial intervention contacts, the SC asks the participant if there are any other questions. Any such questions are addressed immediately, and any uncertainty that the participant expresses about intervention responsibility is discussed and clarified until uncertainty is dispelled. This is the final face-to-face contact with the participant for one year, so care should be taken to ensure that the participant is knowledgeable and confident about his or her role in the study. Following this final discussion, the SC reviews the Baseline Visit Checklist, and each completed item is ticked off. Any omitted steps are completed at this time. Confirm that parking cost has been taken care of, and offer parking tokens if needed. Ensure that the participant knows the way out to parking or other transportation, and escort if desired. E.13 Place examination results in participant’s institutional chart The results of the oral examination, i.e., the surfaces where caries were recorded, should be placed in the participant’s institution dental chart, if the participant is a patient of record in the institution. F. Records Management for the Baseline Examination Visit This visit is “data intense” and “activity rich” in that a good deal of recorded data is generated from a variety of activities. For that reason, a Baseline Visit Checklist form is used to assure that all needed activities and data collection are successfully completed during the course of the visit. The checklist includes the following activities: Eligibility Confirmation form completed Adherence Assessment form completed Side Effects Form Completed Enrollment Medical History Questionnaire reviewed Serious Adverse Event form completed (if relevant) Baseline Questionnaire completed Oral Examination form completed Randomization completed and report signed and dated Randomization form completed, even if participant is not randomized into the study Intervention Information Sheet provided and copy produced Initial supply of mints dispensed and dispensing logged Contact arrangements reviewed Baseline Visit Checklist completed The Participant Research Chart contains the following items: Newly completed or newly updated Baseline Questionnaire Adherence Assessment form Eligibility Confirmation form Chapter 6: Baseline Examination Visit Version 5.0 10/17/08 Page 6-8 XACT Manual of Procedures Side Effects Form Serious Adverse Event form (if relevant) Oral Examination form Randomization form Randomization assignment report printed Intervention Information Sheet (with call schedule) Baseline Visit Checklist Mint Dispensing Log Reimbursement Log Baseline Visit Checklist Baseline Visit Progress Notes Checklist Previously completed (and entered) Run-in Call Notes form Eligibility Questionnaire Demographic form Enrollment Visit Checklist Serious Adverse Event form (if relevant) Enrollment Medical History Questionnaire now initialed and dated by participant The Participant Consent Folder contains the following items: Newly completed or newly updated Intervention Information Sheet with call schedule Contact Information Form Previously completed Original signed/co-signed and dated screening and study consent forms Run-in Information Sheet with baseline visit date and run-in call schedule Chapter 6: Baseline Examination Visit Version 5.0 10/17/08 Page 6-9
