Checklist for keeping participants' interest

Factors and approaches that enhance patient interest and participation
Treat patients with courtesy and dignity
Keep them informed on the objectives/progress of the trial (personal interviews, information leaflets, Web page dedicated to consumers, etc.)
Involve other relatives or friends (especial interviews/information leaflets with specific information for relatives)
Plan a timeline for locating and contacting patients, with actions to be conducted at each period of time (birthday cards, phone calls, home visits, reminders, e-mails, etc.)
Avoid hospital barriers (especial office/clinic schedules minimising waiting time, personnel dedicated to the trial, home visits, etc.)
Consider other possible barriers (transport costs, work schedules, school, housekeeping activities, etc.)
Ensure a proper transfer of patient care to alternate clinic/hospitals when appropriate (referral to high risk units or specialised clinics when a particular condition requiring special care is detected)
Be creative! (you may know many other activities that are not listed here)
