You can't deduce that because oncologist patients often die in 18 month, oncologist are lesser doctors. Patient died because they were so sick when they arrive that there wasn't a lot of hope left.
50% success rate doesn't indicate that recruiting is like throwing a coin flip. If there are only 10% of people that can do the job across interviewee, then throwing a coin would get you just 10% of people able to do the job.
However if there was a pool were 80% of people are able to do the job, getting 50% would be worse than picking anyone randomly.
