Executive Summary

The Michigan Clinical Research Unit (MCRU) provides clinical staff and resources to perform human clinical trial research protocols at the University of Michigan. The Administrative Director reported that an increase in demand (from 15 to 2700 visits since 2007) has led to a chaotic and inefficient model for one of their core clinical services, the Mobile Clinical Research Team (MCRU 2U). Workers within MCRU report inefficiency and high variability in the workflow process, which have resulted in unpredictability in demand, demand exceeding staff capacity, and research protocols that interrupt the daily duties of nurses and medical assistants. To address these problems, workers within MCRU 2U asked an IOE 481 student team from the University of Michigan to conduct a series of observations and analyses to help understand current workflow and recommend an improved workflow. The team was also asked to determine if the current model can be scaled to fit current and future demand or if MCRU 2U needs to be offered as a separate service with more allocated resources.

Project Goals

To help sustain and improve the current MCRU 2U model, the student team achieved the following tasks:

Conducted a series of studies to understand the current workflow and demographic trends within MCRU 2U

Identified sources of inefficiencies, redundancy, disorganization, and variation

Methods

The team performed four types of tasks to evaluate and improve the current MCRU 2U workflow process.

Performed Time studies. First, the student team shadowed 10 mobile visits to understand time between processes and to understand process variability. The team calculated average duration and standard deviation for each process step.

Administered MCRU employee surveys. The team developed and administered a survey to 9 MCRU 2U staff to quantify the opinions of the staff regarding MCRU 2U. The student team further analyzed surveys to reflect on process variability from staff perspective.

Analyzed historical data set. The team analyzed demographic trends from 1590 mobile visits dated between June 2012 and May 2013. The team received this information from the Research Translation Specialist and used it to answer the following questions:

o What day of the week receives a majority of MCRU 2U calls? What is the variability in calls on these days?

o What times are a majority of the calls being received?o What location is being serviced the most based on time of day?o What location is being serviced the most based on day of week?

o What protocols are serviced the most? o What protocols are serviced on the same day within 30 minutes (back-to-back)?

How often? Developed recommendations for improving the workflow. The team created a list of steps

that MCRU 2U could take to understand their demand better and minimize process variability.

Findings

Analysis of the time studies, surveys, and historical data set were divided into two main categories: Process Variation and Volume through Process.

Process Variation Analysis of time studies highlights certain problems within the MCRU 2U workflow process. Process steps in Figure E-1 were grouped into different intervals to help identify these problems. Figure E-1 shows that traveling from MCRU to the site and traveling back to MCRU after the completion of a service accounted for 7 and 9 minutes on average, respectively. Intervals A1 and B2 have high standard deviations, at 6 and 5 minutes, respectively. The high standard deviations means that there is high variation from the time a call is received to when supplies are collected and from the start of a service to the end of a service.

Figure E-1: MCRU 2U Workflow ProcessOctober 9-19, 2013; N = 10; Time Studies

Volume through Processes Findings from the historical data set show that Tuesdays and Thursdays had the highest average number of calls, at 7.32 and 7.10 calls, respectively. In addition, Thursday had the highest variability in calls while Monday had the lowest. Analysis of different time blocks showed that Tuesdays between 11:00 and 13:00 had highest average number of calls at 2.84 calls. Finally, analysis of different locations indicated that Mott Hospital, on Thursdays, had the highest average number of calls at 3.09 calls.

Conclusions

The following section provides the conclusions formed after analysis and evaluation of the findings, which are based on Process Variation and Volume through Processes

Conclusions from Process Variation Analysis of the process variation data showed that there is high variation from the time a call is received to the time staff starts their service, specifically when the calls come from the University Hospital and Mott Hospital. In addition, the amount of time MCRU 2U staff waits to start a service upon arrival at the site needs to be shortened. Finally, walking constituted over 40% of the total process time and needs to be reduced.

Conclusions from Volume through ProcessesAnalysis of the demographic trends showed that MCRU 2U should schedule more staff more Tuesdays and Thursdays, specifically between 09:00 and 13:00. MCRU 2U should plan to service the Taubman Center primarily on Mondays, Tuesdays, and Wednesdays, and Mott Hospital on Thursdays and Fridays. Finally, analysis of all protocols showed that 11% of all protocols are contributing to 50% of total mobile visits from June 2012 to May 2013.

Recommendations

The student team developed a list of short term and long term recommendations to help MCRU 2U increase the predictability of their process and meet demand.

Short Term Recommendations The short term recommendations are actions MCRU 2U can implement in the near future. The team recommends that MCRU 2U implement guidelines and organizational methods that help control the variable demand and predict future calls. This can be done by making the following changes:

Screen investigators during the initial call Add storage units at the most frequently served locations, such as the Taubman Center

and Mott’s Hospital Develop new organizational method for backpack Develop nurse assignments based on demographic trends Regulate calls by establishing guidelines with PIs

Long Term Recommendations The long term recommendations focus on continual improvement and sustainability of the MCRU 2U process.

Clean and validate data regularly so it is easier to understand for all users Record and input data using a standardized method (create organized excel template,

discuss with employees the importance of recording accurate measurements) Regularly analyze (every 3-4 months) trends between times, locations, and protocols to

understand workflow and to assess the need for potential improvements

Perform further studies to analyze demand and potential areas of improvementsIntroduction

The Michigan Clinical Research Unit (MCRU) is a unit within University of Michigan Health Services (UMHS) that provides clinical staff and resources to perform human clinical trial research protocols at the University of Michigan (UM). Many of these research protocols take place at UM’s Cardiovascular Center (CVC). In 2007, MCRU implemented a Mobile Clinical Research Support Team (MCRU 2U) as an addition to its core services. MCRU 2U staff provides clinical research support to clinical investigators. Instead of having participants come into the CVC to perform these protocols, MCRU 2U staff goes to the participant. Since its implementation in 2007, the service has grown from 15 to 2700 visits annually through word of mouth.

The Administrative Director of the Research Innovation Core reported that an increase in demand for mobile visits has led to a chaotic and no longer efficient model. Workers within this unit report inefficiency and disorganization in the workflow process. Inefficiencies result in high variation and unpredictability in the workflow process, demand exceeding staff capacity, and research protocols that interrupt the daily duties of nurses and medical assistants.

To address this problem, workers within MCRU 2U asked an IOE 481 student team from the University of Michigan to conduct a series of tests to analyze the current workflow and to provide an improved workflow. After conducting observations, interviews, and further analyses, the team has determined if the current model can be scaled to fit current and future demand, or if MCRU 2U needs to be offered as a separate service with more allocated resources. This report details the student team’s data collection and analysis methods, and presents the team’s findings, conclusions and recommendations.

Background

MCRU, located in the Cardiovascular Center (CVC), is a unit within UMHS and the Michigan Institute for Clinical and Health Research (MICHR) that provides the clinical staff and resources necessary to perform human clinical research protocols at the University of Michigan. MCRU also serves as an institutional resource, allowing investigators to perform pilot studies. Investigators who are federally, philanthropically, and industrially sponsored are serviced by MCRU.

One of the core clinical services provided by MCRU is the mobile service, MCRU 2U. MCRU 2U was implemented in 2007 with hopes of providing improved access to clinical research support services with little increase in resources. In addition, the mobile service hoped to extend the practice of clinical research outside the MCRU, increase enrollment, and decrease dropout rates.

The clinical staff within the MCRU 2U team provides services and support to clinical investigators. The mobile team services investigators by responding to specialized protocols, which include PK blood draws, ECGs, etc.

The mobile services are offered through three routes: (1) walk-in, (2) just-in-time, and (3) prescheduled services. In the current process, mobile calls come in via telephone, and the responder gathers required information for the visit. After determining what clinical staff will perform the service, the clinical staff member gathers supplies and walks to the service site. After performing the service, the staff member returns to the CVC, delivers the sample and participant data to the laboratory, and documents the visit. Figure 1 details this workflow process.  

Figure 1: Trigger Process for Mobile Clinical Research UnitAdapted From: MCRU JIT Process, Administrative Director and Research Translation Specialist

The inefficiencies begin to surface when high demand for the services occur. MCRU 2U has limited staff and resources and attempting to meet the service demand can lead to disorganization and chaos. For example, there are demographic trends in which certain days, times, or sites will have low demand for the service, but other times will have high demand. The staff who perform these services must also perform their daily duties, which include servicing walk-in participants. The daily duties of the staff can be interfered with on a day with multiple protocol calls. The high amount of variation and unpredictability has prompted MCRU 2U to ask the IOE 481 team to look at demographic trends, inefficiencies and wasted work, and to offer a current and future workflow analysis.

The essential goal was to quantify the current process and identify potential areas of improvement. In addition, the team determined if the existing model can be scaled to meet current and future demand. This project helped identify these key issues and provide recommendations for an improved workflow.

Key Issues

The following key issues are driving the need for this project: Demand has led to inefficiencies Inefficiencies result in high variation and unpredictability in the workflow process Protocol calls interrupt the daily in-clinic workflow for nurses and medical assistants

Goals and Objectives

To help sustain and improve the current model within the Mobile Clinical Research Unit, the student team achieved the following tasks:

Conducted a series of studies to understand the current workflow and demographic trends within the MCRU

Identified sources of inefficiencies, redundancy, disorganization, and variation

With this information, the team developed recommendations to: Determine if the current model is sustainable or if additional resources are needed Increase efficiency Eliminate redundancy Increase predictability

Project Scope

This project included only the MCRU 2U workflow process. The protocol process begins when MCRU 2U is notified of a protocol call and ends when the MRCU 2U staff member returns to the clinic, gives participant data to the lab, and documents the visit. The project scope included the 55 out of the 245 active protocols that require the mobile services of the MCRU 2U.

Any task not connected to the protocol process was not included in this project. Specifically, the team did not study research protocols not serviced by MCRU 2U, or activities associated with departments outside of MCRU 2U. The project did not focus on details regarding participant information nor did it focus on the details involving specific protocol services. The project did not focus on complex protocols such as EKGs.

Methodology

The team developed recommendations based on a select group of simple protocols. This adjustment in focus reduced variation in the workflow process and allowed the team to recommend changes to a more specific function of the MCRU 2U.

Observations and Time Studies

The team observed the MCRU 2U workflow process prior to the time studies to develop a data collection sheet (see Appendix 1) that matched the MCRU 2U workflow process. The team utilized this data collection sheet and a stopwatch to record start and end times for the steps in the workflow process depicted in Figure 1. Data was collected for two weeks. The team observed several staff members and performed 10 time studies on MCRU 2U mobile visits.  

Mobile visit was further divided into the following steps: Arrive at site Start Service End Service Leave site

These steps were chosen because the team wanted to observe the activities before a protocol and the steps following a protocol to understand process variability. Specifically, the team focused on preparation and travel time to a site location to standardize the start and end of each step in the workflow process. Team members utilized the data collection sheet to record staff name, route type, site location, date and time, and notes for each step in the workflow process.

Each member of the student team conducted time studies individually. Data was collected from a random sample of nine MCRU staff. A student followed either a Registered Nurse (RN) or a Medical Assistant (MA) to a location site and recorded times while observing the process.

Research for Workflow and Staff Assignment and Allocation

The team conducted a literature search and each team member consulted three documents. The team searched through past IOE 481 reports and gathered ideas and methods, which have been incorporated into this project.

The first document, titled Operations Research Methods Applied to Workflow in a Medical Records Departments [1], uses both stochastic and deterministic models to analyze a hospital information system, more specifically the workflow of the Medical Records and Word Processing Department at the Madonna Rehabilitation Hospital in Lincoln, Nebraska. The workflow in this paper is described as the way jobs arrive into the department and the way in which they are transcribed. The situation analyzed in the paper is similar to the one at MCRU 2U. The team analyzed a situation where staff requirements and stochastic demand is a concern.

The second document, titled An Integrated System for Patient Assessment and Classification and Nurse Staff Allocation for Long Term Care Facilities [2], explains factors to consider when assessing staff allocation, and proper ways to utilize skill levels of nurses. Constraints include (1) an upper limit on funds available for staffing, (2) legal staffing minimums, (3) limitations on the amount of nursing time available for patient care because of other staff responsibilities, and (4) assurance that patients with high priority nursing needs are not neglected. The student team’s

recommendations focus on nursing assignment and allocation, and this document helped determine the constraints to consider.

Finally, the last article used in the team’s research was the Indian Journal of Medical Ethics [3]. This journal presents three case studies that attempt to find ways to improve inter-departmental cooperation in healthcare settings. These case studies are relevant to the analysis of MCRU 2U workflow because a recommendation is to add storage units in different areas of the hospital.

MCRU 2U Employee Survey

The team created and distributed an employee survey.  Survey questions were discussed with both the coordinators and clients to ensure relevance and importance. The team wanted to gather staff opinions regarding the positive and negative aspects of the current workflow. To quantify staff opinions, question themes included:

amount of work per week use of supplies meeting demand implementation of a new scheduling system

Survey questions were designed to exclude subjective answers. The survey consisted of 9 multiple-choice questions; a comments section; and personal information including name, position, and years with MCRU. See Appendix 2 for the complete survey.

The Administrative Director distributed these surveys on November 1, 2013 and returned the surveys to the student team on November 8, 2013. Nine out of eleven employee surveys were completed. The team and the clients agreed that nine surveys were sufficient in representing staff opinions.

Historical Data Set Analysis

The Research Translation Specialist provided the student team with a spreadsheet of 1,835 MCRU 2U performed mobile visits spanning from June 2012 to May 2013. For each mobile visit, MCRU 2U documented the following information in the spreadsheet:

Date of performed visit Protocol number Nurse Prescheduled or Just-In-Time (JIT) Call time, site time, service time, and lab time Delays encountered Visit location Type of protocol (SOC, blood draw, EKG, Infusion, etc.)

Because the team did not observe any of the complex protocols (EKGs, Infusions, Injections), the team removed these data points from the historical data set as to not confound the analysis of

the simple protocols (blood draws). Therefore, the analysis of the historical data set included only the blood draws, which comprise 80% of the total protocols.

In addition, when initially cleaning the data, the student team found various fields left blank or filled with inconsistent information. After further consultation with the Administrative Director, the student team eliminated all data points with inconsistent and missing information.

After eliminating inconsistent and missing information, and the complex protocols from the historical data set, the team was left with 1590 mobile visits to analyze. The student team extracted demographic information and trends relating to volume of calls and time duration of a visit by variables such as day of the week, time of day, location, and protocol number.

Extracting this data and identifying trends based on the variables helped the student team understand the current model and discuss it with the Administrative Director and the Research Translation Specialist. In addition, it served as a crucial component in developing recommendations regarding nurse assignment and allocation.

Methods for Data Analysis

The student team entered all the collected data (time studies, surveys, and historical data) into three spreadsheets to set up statistical analysis. Each data collection method helped the team to understand the current model and to develop recommendations for a future model that reduces inefficiencies and variability, and improves nurse assignment.

Time studies allowed the student team to understand time between processes and process variability.

Surveys helped quantify the opinions of the staff regarding MCRU 2U. By understanding the opinions of the various staff members who perform these visits, the student team assessed the positive and negative aspects of the current workflow.

Finally, the historical data set was useful in analyzing demographic trends within the data and answering the following questions:

o What day of the week receives a majority of MCRU 2U calls? What is the variability in calls on these days?

o What times are a majority of the calls being received?o What location is being serviced the most based on time of day?o What location is being serviced the most based on day of week?o What protocols are serviced the most? o What protocols are serviced on the same day within 30 minutes (back-to-back)?

How often?

Through Microsoft Excel and Minitab, the team utilized functions, pivot tables, and graphical analysis to stratify data. The team developed a series of tables and graphs to answer the previous questions. Utilizing these tools allowed the team to understand much of the variability in the current process, which then helped the team develop recommendations for improving workflow and reducing variability within MCRU 2U.

Findings and Conclusions

The following section details the data analysis, findings and conclusions drawn from the data. Findings are subdivided by Process Variation and Volume through Processes. Conclusions are given for each finding.

Process Variation

The use of time studies, employee surveys, and analysis of historical data helped identify areas of high variation in the current process.

High Variation in Process StepsThe historical data set identified variation between each process step. Figure 2 depicts the average duration and standard deviation between each step recorded in the historical data. Interval A represents the duration between ‘Call Received’ and ‘Arrive at Site’. Interval B represents the duration between ‘Arrive at Site’ and ‘End of Service’, and finally Interval C represents the duration between ‘End of Service’ and ‘Drop Specimen off at Lab’.

Figure 2: MCRU 2U Workflow Process June 2012 - May 2013, N = 1590, Historical Data Set

Figure 2 shows that interval A had the highest average time and interval C had the highest standard deviation. The boxplot in Figure 3 shows the spread for each interval.

Figure 3: Interval A has Highest Average Process Time and SpreadJune 2012 - May 2013, N = 1590, Historical Data Set

Figure 3 shows that interval A had the highest spread and that interval B had the lowest spread.

Figure 4 shows the extension of intervals A and B based on the variation in processes found from the historical data set. Ten time studies were conducted to analyze the average time and standard deviation between process steps of the current MCRU 2U workflow. Figure 4 displays the specific process steps observed during the time studies.

Figure 4: Extended MCRU 2U Workflow ProcessOctober 9-19, 2013; N = 10; Time Studies

Intervals A3 and C represent walking time, which accounts for the majority of time spent during a mobile visit. Traveling from MCRU to the site and traveling back to MCRU after the completion of a service account for 7 and 9 minutes on average, respectively. The process was further analyzed to identify areas where MCRU 2U could improve on the current process. Improvements of opportunity were chosen based on intervals with high variation. These areas of improvement are shown in Figure 4 as well.

Variation in Protocol LocationsTo further understand the variability of process time due to location, Table 1 shows a comparison of each process step duration for each location.

University Hospital 35.84 9.57 15.69 60.09

Average 22.49 9.07 15.37 46.29

The data represented in Table 1 shows that there is a large range in Average Total Duration. For example, mobile visits to the University Hospital are on average 27 minutes longer than those to the Cardiovascular Center. Additionally, the two highest durations for call to site are for protocols serviced at Mott Hospital and University Hospital with 23.95 and 35.84 minutes, respectively. This trend continues with Mott Hospital and University Hospital for the largest duration for site to service and service to lab.  The Cancer Center and Taubman Center have the shortest call to site duration with 15.95 and 15.82 minutes, respectively.

Variation of Staff Performance and OpinionsBased on the findings from the employee surveys, analysis showed staff opinions on areas for improvement. The surveys had nine questions and nine staff members completed the surveys.

Analysis of the surveys primarily focused on assessing the issues of backpacks and total walking time to and from a serviced location because these two issues best explained the variation in process steps.

The Administrative Director expressed concern that a large number of employees did not take all of the supplies required to perform multiple services, specifically backpacks, on protocols. Questions 2 and 3 in the survey were designed to specifically address the issue of backpacks. Question 2 asked staff how often they take backpacks on a mobile visit. Responses ranged from ‘Always’ to ‘Never’. The results are shown in Figure 5.

7 of the 14 total responses from employees signified that they do not take the backpack on mobile visits because it is too disorganized or too heavy.  

Surveys gathered opinions about the usage of backpacks and walking time to and from a serviced location. Time studies analysis indicated that walking contributed 43% of the total process time. Therefore, the survey asked staff if they felt that walking took a good portion of the total process time. The responses for this question ranged from ‘Strongly Agree’ to ‘Strongly Disagree’. The results from this question are shown in Figure 7.

Figure 7: MCRU 2U Staff Agree Walking Takes a Good Portion of Service TimeNovember 1-8, 2013; N= 9; MCRU 2U Employee Survey

Figure 7 shows that 6 out of 9 employees agree that walking takes a good portion of the MCRU 2U protocol service time. This response emphasizes the need to decrease the amount of time the staff spend walking.

To help the Administrative Director and Research Translation Specialist understand employee’s opinions, survey results related to demand, workload, and a new scheduling system are attached in Appendix 4. The team did not form any recommendations from these results.

Conclusions from Process Variation Analysis of the process variation data showed that there is high variation from the time a call is received to the time staff begins their service, especially when the calls come from the University Hospital and Mott Hospital. In addition, the amount of time MCRU 2U staff waits to start a service upon arrival at the site needs to be shortened. The purchase of a new backpack or organization of the current backpack is necessary. Finally, walking constituted over 40% of the total process time and needs to be reduced.

Volume through Processes

After analyzing the current process variability, analysis of the historical data helped identify demographic trends. Demographic trends help understand the current model, as they provide insight into incoming demand by different frequencies, times, locations, and protocols.

To help understand demographic trends, the boxplot in Figure 6 shows the average number of calls on each weekday.

Figure 8 shows that in the year June 2012 to May 2013, Tuesdays and Thursdays had the highest average number of calls, at 7.32 and 7.10 calls, respectively. In addition, the boxplots help understand the spread of calls for each weekday. For example, the boxplot for Monday suggests that the number of calls on Mondays did not have a large spread and that Thursdays had the largest spread.

Time Range AnalysisTo further understand the demographic trends of the MCRU 2U calls, Table 2 shows the frequency of calls by different time periods. After discussion with both the coordinators and clients, the student team chose to analyze trends in time by two-hour blocks of a typical work week (Monday through Friday, 7 AM to 5 PM).

Each value in Table 2 represents the average number of calls MCRU 2U receives for that weekday and time range. For example, MCRU 2U receives an average of 1.47 calls on Mondays between 07:00 and 09:00. The red circles indicate the time block during which MCRU 2U received the highest average number of calls for a particular weekday. For example, on Monday, MCRU 2U receives its highest volume of calls between 13:00 and 15:00, at 1.96 calls. Similarly, the busiest time block on Tuesdays is between 11:00 and 13:00, with an average of 2.84 calls. On Wednesday, two time blocks (09:00 – 11:00, 11:00 – 13:00) tied for highest volume of calls, averaging 2.00 calls. Finally, on both Thursdays and Fridays, the busiest time block is between 09:00 and 11:00, with average of 2.78 calls and 2.54 calls, respectively.

Location AnalysisTable 3 looked at the demographic trends within certain locations that MCRU 2U services. After discussion with the Administrative Director, analysis focused specifically on the six locations shown in Table 3.

The values in Table 3 are similar to the values in Table 2. Each value in Table 3 represents the average number of calls received by MCRU 2U for a particular location for some weekday. For example, MCRU 2U received an average of 1.54 calls at the Cancer Center on Mondays. The red circles represent the location with the highest volume calls for a particular weekday. For example, on Mondays, Tuesdays, and Wednesdays, the MCRU 2U serviced at the Taubman Center the most frequently, with an average of 2.08, 2.03, and 2.14 calls, respectively. Finally, on Thursdays and Fridays, MCRU 2U serviced at Mott Hospital the most frequently, with an average of 3.09 and 2.07 calls, respectively.

Protocol AnalysisMCRU 2U serviced 92 protocols between June 2012 and May 2013. The Pareto Chart in Figure 9 depicts demographic trends found for the serviced protocols.

Figure 9: Five Protocols Contribute 31% of Mobile VisitsJune 2012 - May 2013, N = 1590, Historical Data Set

The Pareto Chart in Figure 9 shows the number of total calls serviced by different protocols. For example, the first protocol, ‘2643’, had 8% of all mobile visits between June 2012 and May 2013. The Pareto Chart shows that the top five most frequently serviced protocols (‘2643’, ‘2730’, ‘2441’, ‘2742’, ‘2717’) made up 31% of all mobile visits from June 2012 to May 2013 and that the top 10 most frequently serviced protocols made up 50% of all mobile visits. Finally, Figure 9 shows that out of 92 total protocols, 19 of them contributed to 71% of all mobile visits. To see the relative frequency and cumulative frequency of each individual protocol, see Appendix 3.

Table 4 shows further analysis of the top five most frequently serviced protocols. To perform the analysis, the student team created a parameter called ‘Back-to-Back Frequency’. This parameter measured the occurrence of two mobile calls received within 30 minutes of each other. Table 4 shows the top five most serviced protocols, the number of times each protocol had a ‘Back to Back’ call, the average number of ‘Back-to-Back’ calls per day, the number of days with ‘Back-to-Back’ calls, and calls per day.

2717 23 0.46 16 1.60

Table 4 shows that protocol ‘2643’ had the highest back-to-back serviced. Of the top five most serviced protocols, protocol ‘2717’ had the lowest number of total services and back-to-back services. In addition, Table 4 shows that protocol ‘2730’ had the highest average of ‘Back-to-Back’ calls and protocol ‘2742’ had the lowest. Protocol number ‘2643’ had the highest number of days with back-to-back calls at 30 days, and protocol number ‘2717’ had the lowest number of days with back-to-back calls at 16 days. Additionally, both protocol ‘2643’ and ‘2742’ received 1.86 calls per day, on the days they were serviced. Comparatively, protocol number ‘2441’ received the lowest amount of calls per day at 1.18 calls, on the days they were serviced.

Conclusions from Volume through ProcessesAnalysis of the demographic trends signified that MCRU 2U needs more scheduled staff on Tuesdays and Thursdays, specifically between 09:00 and 13:00. MCRU 2U should plan on servicing the Taubman Center primarily on Mondays, Tuesdays, and Wednesdays, and Mott Hospital on Thursdays and Fridays. In addition, analysis of the 92 protocols showed that 11% of all protocols are contributing to 50% of total mobile visits between June 2012 and May 2013; therefore, MCRU should implement guidelines to increase predictability of known mobile calls from the most serviced protocols.

Table 5 is used to determine if the current model is scalable or if MCRU 2U should be offered as a separate service.

Table 5: Expected Man Time and Staffing Requirements at 80th percentile (minutes)June 2012 - May 2013, N = 1590, Historical Data Set

The value of each cell in Table 5 represents the amount of man minutes needed to operate MCRU 2U at staffing levels of the 80th percentile. In addition, each cells shows the expected number of staff needed assuming 120 minutes per staff member. For example, the man minutes, at the 80th percentile, required on Mondays between 07:00 and 09:00, was 92 minutes. These 92 minutes are equal to staffing one person for this shift. The red circles highlight the time blocks and weekdays with the most required man minutes and staff. For example, Tuesdays between 11:00 and 13:00 require 212 man minutes and staffing of two MCRU 2U people. Similarly, Thursdays between 11:00 and 13:00, and Fridays between 09:00 and 11:00 require MCRU 2U to staff two people.

The analysis from Table 5 shows that MCRU 2U demand can be scaled; however, the amount of required staff shown in Table 5 should be specifically for the MCRU 2U service. It is most appropriate to staff Medical Assistants (MAs), particularly for the simpler protocols.

Recommendations

The student team developed a list of short term and long term recommendations to help MCRU 2U increase the predictability of their process and meet demand. The short term recommendations are actions MCRU 2U can implement in the near future. The long term recommendations focus on continual improvement and sustainability of the MCRU 2U process.

Short Term Recommendations

The team recommends that MCRU 2U implement guidelines and organizational methods that help control the variable demand and predict future calls. This can be done by making the following changes:

Screen investigators during the initial call by asking the following questions and steps: o Will MCRU 2U staff be able to start service upon arrival?o Does the PI have the proper consent forms? o Does the protocol location have the appropriate equipment?

o Provide a thirty minute time range of when the patient will be ready. o If MCRU 2U can start service upon arrival, proceed with call as usual.

Add storage units for supplies at the most frequently served locations, such as the Taubman Center and Mott’s Hospital

o Coordinate and discuss with other hospital units about installing storage units. These storage units can help to reduce walking time between protocols serviced at the same location.

Develop new organizational method for backpacko Organize supplies for easy and accessible usage. This will incentivize staff to use

backpack on mobile visits. Develop nurse assignments based on demographic trends

o Use trends related to location, time range, and weekday to assign appropriate staff levels that meet demand of MCRU 2U

Regulate calls by establishing guidelines with PIs and protocolso Accept no more than 2 calls per hour for a particular protocolo Develop more prescheduled visits with most serviced protocols to increase

predictability in demand o Require PIs to notify MCRU of multiple calls for a particular location that will be

within one hour

Long Term Recommendations

Clean and validate data regularly so it is easier to understand for all users Record and input data using a standardized method (create organized excel template,

discuss with employees the importance of recording accurate measurements) Regularly analyze (every 3-4 months) trends between times, locations, and protocols to

understand workflow and to assess the need for potential improvements Perform further studies to analyze demand and potential areas of improvements

Expected Impact or Outcome

Using the results from this report, the team has provided recommendations that will improve the productivity and efficiency of MCRU 2U. The following is expected upon project completion.

Understanding Process Variability

MCRU 2U has shown significant variability in the mobile process. Standardizing this process by screening investigators will shorten the total process time by 5 minutes. Organizing the backpack will incentivize at least 4 out of 9 staff members to take it with them on mobile visits, which will then reduce walking time during ‘back-to-back’ calls.

Understanding Volume through Processes

Implementing changes based on the demographic trends of location, protocol, and time of day will allow MCRU to better predict demand and the expected number of man time required for MCRU 2U, resulting in variation reduction and allowing MCRU to staff appropriately for the mobile service. This will improve the overall quality and efficiency of the service.
