Either move all other patients down one position or make an array of pointers to patients and allocate them dynamically. Then you can delete the patient at a certain position and mark the position as free by setting the pointer to 0.
Since your array seems to play a double role of also acting as a id->patient map, the latter is probably the better solution.

Of course, you could just use a real map.
