Assisted deaths in Switzerland for UK residents: diagnoses and their implications for palliative medicine and assisted dying legislation

UK campaigners for a law permitting assisted dying (AD) restricted to those with a maximum life expectancy of 6 months claim that this would largely remove the need for UK residents to seek AD in Switzerland. We wanted to discover whether this prediction was correct. We analysed the diagnoses of UK residents who had such deaths including, for the first time, data from all three of the main Swiss providers of AD to non-residents, comparing them with figures from Oregon, which has a 6-month restriction. Only 22.7% of UK residents had cancer (Oregon 72.5%) while nearly half (49.6% and over half including dementias) had neurological conditions (Oregon 11.2%) and many with prognoses of much more than 6 months. Overall, less than half would meet a 6-month prognosis criterion. This has significant implications for patients, palliative care clinicians and legislators.
