3 Abstract MD Anderson's enhanced reputation for quality imaging studies is helping its MRI volume grow at an annual rate of 3%. This growth has placed the scanners close to capacity, and it is difficult to absorb new patients. The study describes how MRI imaging protocols and processes were improved using Lean tools, thereby reducing overall procedure time. Also, image quality was optimized, resulting in an enhanced guide to treating patients.

4 To improve processes and enhance quality is aligned not only with MD Anderson’s goal but also with the Institute of Medicine’s goal of redesigning care delivery.

5 Aims The purpose of the study was to rethink MRI processes and protocols in a new and dynamic way to reduce overall procedure time so additional patients can be added to the schedule. Also, image quality was optimized, resulting in an enhanced guide to treating patients.

6 Methods The study team used Lean tools to generate and implement 31 new ways to either build or rebuild current MRI processes. Examples include developing new schedules and pre-screening patients for implants and anxiety. In addition, DMAIC provided the framework for carrying out the study in a systematic manner. Tools included: Process Flow Diagram, Fishbone Diagram, Voice of Customer, Control Charts, etc. Owing to the large volume of abdomen and/or pelvis procedures, the study team decided to target these procedures for improvement. Scan time, table time, and acquisition time were used as the metrics.

7 Learning Objectives Application of Lean tools in improving imaging/protocol processes. Understanding how best practices in the PET area were used to develop process and quality improvement solutions in MRI. Understanding how “image sequences“ which are building blocks of a protocol can be standardized.

8 What to do (statistically) if bimodal data shows up in your analysis How the “Control” phase in DMAIC methodology played a role in sustaining the improvement process.

9 Background Some process improvement in performing MRI studies has been undertaken in the past two years but has not involved reviewing activities at the protocol level. The sequences are the core building blocks of any protocol. Without examining this buildup, the selection of a single protocol for abdominal MRI, to require protocol prescription 24 hours in advance, and guidelines for contrast agent selection, cannot be administered consistently.

10 The reason, an examination of the sequence has not been performed previously is that although both table time and machine time have been captured in a GE database in real time, this information has been unavailable for analysis by end-users owing to proprietary issues and HIPPA compliancy. GE, one of the two MRI vendors, was very helpful and created a customized HIPPA-compliant report with meaningful information for protocol analysis.

11 Literature states eight types of waste (MUDA), shown in Table A. Application of Lean tools in improving imaging/protocol processes. Transportation Overproduction Inventory Over-processing Motion Defects Waiting Standards Lacking Table A A fishbone diagram indicated the following as the main causes of waste in the MRI department: Technicians with different levels of training Restricted scheduling of slots Customized protocoling for each patient Handoffs from technicians to radiologists. Standardized work

12 One quality tool that was used extensively was the “Voice of Customer” tool to gather customer requirements at all stages of the study. Cause and Effect Diagram Improve Process

13 Process Flow Diagram Microsoft Visio was used to process and diagram the steps needed for lab and protocol-approval processes. The analysis indicated that the work process included many delays and calls to radiologists.

14 Baseline Metrics Baseline metrics for scan time, table time, and acquisition time were established using calendar year 2012 data. The Minitab software package was used to calculate statistics. The table summarizes January 2012 through December 2012 data for scan time (RIS), table time (GE), and acquisition time (GE). These data provided us with targeted goals to achieve at the end of the study.

15 Understanding how best practices in the PET area were used to develop process and quality improvement solutions in MRI. MD Anderson is a large institution, and imaging modalities (PET, MRI, CT, NM, etc.) are housed in different buildings and locations. Thus, we were able to use other imaging modalities’ experience as a benchmark for the study. Some best practices were borrowed from the PET area, where these solutions had successfully worked in the past.

16 The study team brainstormed solutions to generate 32 new ways to either build or rebuild current MRI processes for improvement. Solutions included modifications in the current practice of radiologists, technologists, and nurses. Among these, the most effective and far- reaching were the selection of a single protocol for abdominal MRI, a required protocol prescription 24 hours in advance of imaging, and guidelines for contrast agent selection.

17 Some of the other interventions were: Develop a new schedule to optimize MRI slots based on time data Preview patients for all slots Enforce the anxiety policy and educate patients on pre-meds Educate technicians to standardize the RIS entry tracking process Pre-screening every patient 1-2 days out for implant clarifications Enforce policy and educate patients on “HARD STICKS”

18 Understanding how “image sequences," which are the core building blocks of a protocol can be standardized. or without contrast and pelvis with or without contrast represented 21% of the total volume of the top 10 MRI procedures. Also, senior leadership including the chair of diagnostic imaging were interested in making improvements in this area. Analysis of data from February 2012 to December 2012 indicated that combined MRI of the abdomen with

19 Some of the sequences used to build MRI ABD with or without contrast are shown in the table on the next slide. Sequences described in the “Series description” column varied from patient to patient and from radiologist to radiologist. The abdominal section radiologists standardized the exam and published one protocol. Exceptions or additional sequences were added owing to patients’ conditions and were noted in the patients’ charts.

20 The metrics average exam time, average machine time, and number of sequences per procedure were used to monitor improvements and compliance with the requested changes.

21 What to do (statistically) if bimodal data shows up in your analysis Statistical analysis was done to assess the acquisition time data for MRI ABD with or without contrast procedure. The analysis indicated that the data were bimodal, which indicated that the data contained two different clusters or protocols. ABD with or without contrast procedure with different protocols embedded in the data Mean Time ~ 49 minutes

22 Mean Time ~ 37 minutes ABD with or without contrast procedure with ABD protocol only If details are not available, then cluster analysis could be used to calculate the means. However, in our example, we did a more detailed analysis by separating the protocols in the data and then calculating the means.

23 How the “Control” phase in DMAIC methodology played a role in sustaining the improvement process. Control charts were used on a monthly basis to monitor the reduction in scan time, table time, and acquisition time. If the control charts showed an upward trend, we reviewed the sequences to see if the radiologist’s or technician’s practice pattern changed.

24 Results Overall scan time was reduced by 10%.

25 Conclusions Findings suggest that the team achieved a 10% decrease in overall MRI scan time. Lessons learned include: -Incremental process changes can result in large savings. -Statistical tools are great investigative tools for large data sets. An imaging procedure could contain as many as 32 sequences. -Lean methodology and DMAIC framework yielded a successful study.
