Campaigner and Journalist
In June 2005 at the age of 18 Tinsley began writing for The Irish Times on the state of Cystic Fibrosis care in Ireland. Her work launched a lengthy campaign to improve healthcare services and awareness of cystic fibrosis in Ireland. The campaign spanned several years and was a nationwide community effort sustained by the stories and energy of people with CF and their families and communities around Ireland.
In September 2008 she was named Rehab Young Person of the Year  In April 2009 she appeared on Late Late Show after writing several pieces in The Irish Times holding government to account on broken promises to build an adult cystic fibrosis unit in Dublin. In November 2009 she was named Irish Tatler Magazine's Woman of the Year  in 2009. In 2010 she was awarded the Young Medical Journalist of the Year award.
The Adult Cystic Fibrosis Unit
An Adult Cystic Fibrosis practice was set up at St. Vincent's Hospital in the late 1970s by Professor MX Fitzgerald. CF was one of the first conditions to be treated by a multidisciplinary team comprising doctors, dietitians, physiotherapists, psychologists and nurse specialists. Huge improvements in life expectancy were achieved in this period but when advances in microbial genetics revealed how highly-resistant and life-threatening bacteria could spread through the CF patient population, it became clear that a dedicated space was required to treat CF patients in isolation from one another. There was no dedicated CF ward at this time and it took years to convince those in power to build one. In July 2012, after campaign work over numerous years, a dedicated Cystic Fibrosis Unit opened. The ward block has an outpatient and inpatient facility for people with cystic fibrosis. It also has a floor of isolation rooms for people with cancer and another floor for those with infectious diseases who need isolation.
Since 2012 Ms Tinsley has focused on the rights of transgender people to attain gender recognition in Ireland. She was named Broadcaster / Journalist of the Year by the Gay and Lesbian Association in 2013.
New Cystic fibrosis Drug
In late 2012 she launched a campaign to get Kalydeco into Ireland after experts rejected making the drug available because it was too expensive. The drug is the first to treat the cause of cystic fibrosis and not just the symptoms. In February 2013 the Minister for Health announced that the drug would be made available.
Since late 2013 Ms Tinsley is one of the first people in the world to be treated by the second new cystic fibrosis drug lumacaftor/ivacaftor which treats the most common mutation of CF. The drug has proven to improve lung function and health for people with CF.
