The organisation asked for the views of Parkinson's Disease Nurse Specialists (PDNS) on how treatments for the disease are being administered and their response indicates that there are serious problems when it comes to giving patients their medication.
Not a single PDNS thinks that Parkinson's patients in hospitals are guaranteed to receive their medication on time and seven out of ten said that patients could not rely on getting their medication punctually.
In addition, nine out of ten nurses believe that patients were developing further problems and staying in hospital longer because of missing out on their medication or often receiving it late.
Steve Ford, chief executive of the PDS, said: "This is not about the numbers of nursing staff. It's about wanting hospital employees to understand Parkinson's better and what happens to people when they don't get their medication on time."
The PDS has launched a campaign called Get It On Time to help improve the timing of medication situation for Parkinson's sufferers in hospitals and care homes and it has urged hospital and care home staff to listen to people with the disease, their carers and their families.
