Donna, I work in the NHS and yes I agree it does take a long time for application processes to work their way through to being offered a job. However I recruit from time to time, and my experience is that your new employer will be asked about your absence record, and we can ask for medical reports once you have been offered the job, but the conditional offer letter says "offered the job subject to satisfactory references, occupational health clearance and CRB clearance". The NHS is under great strain at the moment, and as others have said, people work very hard and under sometimes difficult conditions - we are under budget reviews all the time these days. If you can take the NHS job and your employer gives you a reference which pleases your new employer, I wish you good luck - I wouldn't change it, I enjoy my job, but it's hard work at all levels these days!
