N. Rodriguez ("Health Care Applications of Statistical Process Control: Examples Using the SAS System," SAS Users Group International: Proceedings of the 21st Annual Conference, 1996) illustrated several informative applications of control charts to the health care environment. One of these showed how a control chart was employed to analyze the rate of CAT scans performed each month at a clinic. The data used in this example are shown in Table 7.21. NSCANB is the number of CAT scans performed each month and MMSB is the number of members enrolled in the health care plan each month, in units of member months. DAYS is the number of days in each month. The variable NYRSB converts MMSB to units of thousand members per year, and is computed as follows: NYRSB = MMSB (Days/30)/12000. NYRSB represents the area of opportunity." Construct an appropriate control chart to monitor the rate at which CAT scans are performed at this clinic.
