Please try the below code:

def patientName = []
patientName = GlobalVariable.patientList
int length = patientName.size()
    
println "---->"+ length
    
int min = 0;
int max = length-1;
int random_int = (int)Math.floor(Math.random()*(max-min+1)+min);
    
def patientRetrieve = patientName[random_int]
println "---->"+ patientRetrieve
