how can I determine if there is a significant difference in 3 groups of 2 varibles?


3 different intensive care units
ICU 1 had 437 patients and 59 recieved an intervention
ICU 2       222                    77
ICU 3       762                    91
 
is there a difference in rate of use of the intervention among these ICUs?

In order to find the difference of the variables I first subtracted the number of patients from the patients that were intervened
 
  1.  ICU1->  437-59=378
  2. ICU2-> 222-77= 145
  3. ICU3 -> 762-91=671
 
Next, I subtracted the ICU difference to each unit 
1. ICU1 (378) - ICU2 (145) = Was a difference of 233
2. ICU1 (378)- ICU3 (671)= 293
3. ICU3 (671) - ICU2 (145)= 526
 I then subtracted the difference from each unit by the other units to get the remaining answers.
