Motivation: the problem
• Between 5000 – 8000 rare diseases afflicting 6% – 8 % of the world’s population; 55 million in the US and EU (Song et al., 2012)
• Definition: Rare - based on prevalence Orphan - a market where no profit can be
extracted
• Need is extremely high• Rare diseases are frequently chronic and disabling• Patients can expect little help available from producers
or health care• The patients are clinically and scientifically
underserved (e.g. Griggs et al., 2009)
British engineer, Tal Golesworthy (a Marfan syndrome patient), designed own heart implant and saved own life (2004)

Research Questions
RQ1: What are the levels of innovation activity among rare diseases patients? RQ2: What drives patients to innovate? RQ3: To what extent do patients diffuse their solutions, and when is it likely to occur?

• 52% of our sample of rare disease patients and/or their non-professional caregivers have developed improvements
• 15% of these were new-to-the-world (judged new to the world by our expert clinician raters)
• An estimated 6% to 8% of the world’s population – hundreds of millions of people - are afflicted by rare diseases.
• a massive, non-commercial source of medical innovations exists, hidden due to a lack of diffusion efforts by innovating patients
23
Conclusions
• Mode of sharing: patient-to-patient (88% of those who shared solutions) vs 6% of patients reported describing their innovations to their clinicians.
• Contributions by patients may complement the efforts by policy makers, research entities, and producers, to help improve the difficult situation of rare disease patients, whose needs for innovations are often underserved.
24
Conclusions
• Sample:
• Potentially biased towards active individuals: patients and caregivers are retrieved from a population of those who have already reached out towards the rare disease association for help via a helpline.
• Our respondents are dominantly women
• Estimates of frequency:
• Telephone interviews rather than site visits are likely to understate the level of patient and caregiver innovations that actually exist.
• Validation:
• No external evaluation of the efficacy of reported solutions. Self-assessment of satisfaction inflated.
• Measures:
• Quality of life measure is a single item scale; limits the ability to compare it across different individuals. 25
