Summary
Brief summary (as posted)
Rectal toxicity limits dose escalated intensity modulated radiotherapy (IMRT) for prostate cancer. The dose volume constraints that predict for rectal toxicity require minimizing prostate motion and rectum and bladder filling of IMRT .5-15 . The volumetric changes and internal organ motion during prostate IMRT increases risk of PSA failure in patients with large rectums at the planning CT scans. Patient preparation for IMRT planning is crucial .The literature is limited regarding the effectiveness of educational intervention with behavioral reinforcement for patients, and a gap if exists literacy level is considered. Patients often cannot comprehend verbal or written instructions and have difficulties following through with recommended regimens.23 Using multimedia such as Internet, audio-visual media such as DVD and even the telephone can enhance patients' knowledge and understanding about importance of preparation for IMRT for prostate ca. Thomas's study showed that in patients undergoing radiotherapy and chemotherapy, the video group had lower anxiety scores compared with the non video group. At SOCC patients have been provided with verbal information about bladder and rectum preparation for prostate planning CT scan and IMRT. Patients should have a "fullish" bladder and empty rectum at the time of CT simulation. If the rectal diameter is \> 4cm, the patient will be asked to empty his stool/gas and re-scanned. The 3- months review of patients preparedness for prostate IMRT showed that only 13/55 patients were adequately prepared but 42/55 (76%) of patients needed to be re-scanned due to inadequate bladder (21/42, 50%) or rectum filling 28/42, 67%) . Also, 2/13 (15%) patients were still not prepared at the second resimulation despite that they received a phone call with the instructions. The investigators plan to investigate if a multimedia education strategy will decrease costly resimulation rate for patients with prostate cancer.

- Patients will receive the standard are to prepare them for their planning CT scan. They will be presented with the flyer that will be developed based on information about the importance of rectal and bladder preparation that is currently provided to patients and will also watch a youtube video on how to prepare for their CT simulation appointment. A few days before the CT planning appointment, patients in this group will be called by the radiation therapist or RA, reminding them about the rectal preparation for the appointment. Each patient will also be reminded to watch the instructional video on YouTube. Patients will be asked not to share the video link with other patients during the study.

- Patients in this group will receive the standard care to prepare them for their planning CT scan. They will be presented with the flyer at the consultation. A few days before the CT appointment, patients in this group will also be called and reminded about the required preparations, but will not be told about the video. In addition to the statistics about patient preparedness collected by the radiation therapist conducting the CT scan and stored and secured in an OCC Pinnacle planning system, we will also evaluate: patients' satisfaction with the preparation instructions, their knowledge (knowledge questionnaire) about the video content and importance of understanding the rectal emptying procedures, and radiation therapists' satisfaction with patients' rectal preparation.
