Want to know which treatments work best? Try asking patientsby Sophie Petit-Zeman / June 22, 2010 / Leave a comment
If you wanted to study the effectiveness of epidural pain relief during labour, asking mothers how well it worked might seem logical. Yet the last major review of nine studies in this area found that only two of them asked patients about the experience.
Traditionally, research has relied on applying professional expertise to complex problems, and thus contributing to the holy grail of evidence-based medicine. But now the value of “patient and public involvement” (PPI) is becoming clear. Research into osteoarthritis of the knee, for example, was for decades dominated by trials of nonsteroidal anti-inflammatories (aspirin-like drugs). This changed only when patients and those treating them were asked what they wanted, which was studies of surgery, physiotherapy and coping strategies. Such measures can dramatically improve lives, says John Kirwan, professor of rheumatic diseases at Bristol University.
Yet this shift is leaving some in medicine’s ivory towers feeling threatened. Patients can only provide anecdote, they argue. And do patients really want to be involved anyway? Just as we hope schools know how to teach, or garages know how to fix a rattling exhaust, isn’t it better to let medical researchers get on with their jobs?
Some £3bn of public money goes into medical research each year, with roughly £1bn coming from charities and the rest from the government—and much of this charity support comes from donors driven by personal experience. Could more be done to ensure their money is spent effectively? Emma Halls, chief executive of the Prostate Cancer Research Foundation, thinks so. “British prostate cancer charities spend about £1m on research annually, the US about $150m, yet where are the breakthroughs? It begs asking whether we’re researching the right things.”
Seeking answers, Halls is developing a unique approach to marrying patient experience with medical expertise, in partnership with the James Lind Alliance (JLA). Named after the 18th-century Scottish naval surgeon who carried out one of the earliest controlled trials—to find whether citrus fruit cures scurvy—the JLA unites patients/carers and clinicians to identify unanswered questions about how illnesses should be treated. This project is one of several under way; both of those already completed, in asthma and urinary incontinence, have identified significant research gaps.
The JLA is also investigating whether the drugs industry can better meld profit motives with patient benefit. One route being explored is whether the industry and the National Institute for Health and Clinical Excellence (Nice)…
