Do you have a career goal in mind?
My guess is that you aren't looking to pursue a career as a Psychologist, however, if you are, then you'll need to do the Psychology degree (combining it with something else will not make a difference one way or the other). If you're looking at other roles within healthcare, then it will depend on exactly what that role is.
Psychology teaches a number of transferable skills, though not really more than many other degrees. You learn some statistics, which is useful (as you may not pick up the same level of transferable skills in another degree that teaches similar levels of stats). You won't learn anything vocational and by itself, you won't be qualified to do anything specific. For general graduate scheme type jobs, you'll probably be fine provided you get a good classification and have good skills as a person. Some of the higher flying jobs will probably prefer some 'harder' subjects.
At the end of the day, unless you have a career in mind, its very hard to say.
