CASE NOTES: The second tab of this spreadsheet contains data for the OLD & the NEW MRI process including a diagram of the process for one machine. In the past the hospital has used 3 machines simultaneously with 2 nurses & 2 technologist per machine. The Hospital Director has carefully examined the process & revised it creating a new Precedent Chart. (See tabs at bottom of the spreadsheet.) Changes are based on a new MRI machine capablities & re-configuringOLD MRI PROCESS DATA CALCULATION FROM 2022 STATION ONE STATION TWO STATION THREE STATION FOUR TASK ID TASK DETAILS TIME PRECEDING TASK Historical Number of Patients TASK TIME TASK TIME TASK TIME TASK TIME A Check In Wait Time 40 NONE Highest 2022 Patient Count 1123 (Spring Season Only) A H J L B Escort to Change Area 5 A Number of MRI Machine 3 B I K M C Blood Pressure Reading 5 A Patient per Machine C N O D Review Patient Scan Instructions & Releases 8 A Patients per Week (Assume 12 Weeks per Season) D E Escort to Scan Room/Table Assist 3 B,C,D Available Work Time: E F Patient Verification 1.5 E Days per week 5 F G Body Position Check 6 E Shift Hours per day 8 G H Set Up Scan Parameters 12 A Total Available Work Time Minutes Per Week I Perform Scan 40 F, G, H Theoretical Line Balancing Calculations STATION TOTAL TIME: J Quality Check 10 I TAKT TIME K Burn Patient CD 3 J Throughput STATION TOTAL IDLE TIME: L Assist Patient Off Table 2 J Number of Work Stations M Escort to Change Area 15 K, L Actual Line Balance Calculations N Code & Transmit SCAN to Radiology 2 K Total Number of Work Stations HINTS: Station Idle Time is equal to the extra unused time compared to the longest Station Time.
