Rare Patient Voice recruits patients and caregivers wherever they are, including at awareness walks, disease-specific meetings and conferences, on social media, and through recommendations and word of mouth. Patients and caregivers sign up with us solely to take part in surveys, interviews, and other studies. They are excited to participate. They know we keep their information private, and that they will get paid for their time. In addition to recruiting at in-person events, our patient outreach team is always busy developing relationships with referral partners, advocacy groups, and patient support networks throughout the world.
Here are our current patient and caregiver counts by condition and country. If you do not see the information you are looking for, please contact requests@rarepatientvoice.com.

For each type of cancer, patients are identified by stage of cancer, stage of treatment, age, and geographical location.
Clients continue to tell us how impressed they are with the high quality of our respondents. This is a result of:
- Source – we recruit patients personally at advocacy events and other patient events. We partner with online advocacy and support groups.
- Vetting – We vet each patient and caregiver who signs up both manually (looking at the answers to questions about the condition and treatment) and technologically (does their contact information match independent sources? are IP addresses unique?). If unsure, we contact the patient directly and discuss. Amazing how fraudulent entries will simply go away.
These practices set our respondents apart from those screened across the general population (“please check all the conditions you have”). It takes more time and attention, but we feel the highest quality data is certainly worth it.
With more than 40 years in market research experience on both the client and supplier side, we are happy to give you advice on the design of your research. And since we know our panelist very well, we can advise you on the best way to work with them to get the insights you and your clients require.
