The latest Ipsos MORI poll shows that Labour has extended its lead over the Conservatives as having the best policies on healthcare.
A third of people said Labour has the best policies on healthcare compared with 21% who say the Conservatives and 11% the Liberal Democrats.
It means that Labour lead the Conservatives on this issue by 16 points, compared with nine points in March last year. This is the highest Labour lead on healthcare since 2002, Ipsos MORI said.
Many respondents were worried about how the reforms will impact on waiting times, with 44% fearing they will get worse over the next 12 months. A further 35% of respondents were worried that standards of treatment will suffer.
But the survey also showed respondents thought GP services will suffer the least, with just over half of saying that standards will remain the same in this sector.
