Trends Pressuring Sterile Processing Departments

Higher surgical volumes Overburdened process capacities Inadequate instrumentation availability Reduced or under-skilled staff Viable sterile process outsourcing

alternatives

Page 3: Optimizing Sterile Processing Workflow

New View of SPDs as Factories

Lean Process

Concentrates improvement effort on workflow (value stream)

Identifies waste Eliminates waste Eliminates process variability

Page 4: Optimizing Sterile Processing Workflow

Processing Circular flow

Increasingly efforts are being directed toward improving the circular flow of reprocessing work from the O.R. through the SPD and back, with the goal to:

Produce more quality Produce higher quality Improve process efficiency Work with same resources

Page 5: Optimizing Sterile Processing Workflow

Workflow Optimization

Developing processing to promote rational, logical and efficient workflow

In a hospital SPD, you must determine: What is of value to customers How to deliver more value to them How to accomplish more with available

resources How to satisfy the supply needs of the O.R.

Page 6: Optimizing Sterile Processing Workflow

Why Does Workflow Matter?

Eliminates non-productive, repetitive tasks Cultivates an environment that seeks to

improve efficiency Strengthens customer relationships Reengineers processes to be leaner and

more productive Positions SPDs for growth

Page 7: Optimizing Sterile Processing Workflow

The Costs of Inefficiency

Ineffective and inefficient workflows often go unexamined, unmeasured and unmanaged.

Poor workflow compromises: Effectiveness of the operation Level of customer service Many areas of the healthcare facility

SPD staff OR staff Technologies

Page 8: Optimizing Sterile Processing Workflow

Efficient SPD Workflow

Incorporates reprocessing operation and related systems

Automates when possible Eliminates redundancy Eliminates process variability Reduces errors Increases speed Improves quality

Page 9: Optimizing Sterile Processing Workflow

Ultimate SPD Workflow Goals

Characteristics of Optimal Workflows

Compatible with current systems and they streamline existing methods

Applicable across similar functional departments

Consistent

Page 11: Optimizing Sterile Processing Workflow

What Managers Should Know

To ensure process improvement success: Take Action

Gather information Analyze it Determine action steps Implement them Then, do it again

Page 12: Optimizing Sterile Processing Workflow

“Now and better is better than perfect and never” –unknown

“Just do it.” –Taiichi Ohno, former vice president of Toyota Motor Corporation

Page 13: Optimizing Sterile Processing Workflow

What Managers Should Know

Actively involve employees and customers Staff understands pitfalls and makeshift

operations Staff is available, valuable, and willing creative

resource Customers will be happy to help you improve

product and service level Customers can identify potential change

impact Customers also creative resource

Page 14: Optimizing Sterile Processing Workflow

What Managers Should Know

Be prepared for resistance

Change is hard work in an organization People have a natural reluctance to change Change challenges comfort zones Proposed change is threatening

Page 15: Optimizing Sterile Processing Workflow

“It must be considered that there is nothing more difficult to carry out, not more doubtful of success, nor more dangerous to handle than to initiate a new order of things.”

---Niccolo Machiavelli

Page 16: Optimizing Sterile Processing Workflow

What Managers Should Know

Leading Change Show dedication to the improvement process Leading change is not a part-time job Change requires daily attention Don’t get caught up in daily distractions Engage the services of a knowledgeable

change agent Facilitate improvement process Plan and lead improvement activities Demonstrate and teach effective techniques

Page 17: Optimizing Sterile Processing Workflow

Another Day in CS!

Page 18: Optimizing Sterile Processing Workflow

Step 1: Mapping your Central Sterile Workflow

Optimizing the sterile processing functions first begins with a process flow and map. Visual representation of the reprocessing

cycle Focuses initially on the primary process steps Dives deeper into the process to uncover

process layers of complexity

Value Added Activities

Process maps help in identifying value-added activities within the process

Characteristics of Value Added Activities Customer is willing to pay for Physically improve the fit, form, or function of

an item Performed correctly the first time

Page 21: Optimizing Sterile Processing Workflow

Non-Value Added Activities

Non-value added activities = Waste Characteristics of Non-Value Added Activities

Take time, resources, or space but do not add value to the product

Rework at any point in the process Searching or waiting for instruments or

supplies Waiting on machine cycles Double handling

Page 22: Optimizing Sterile Processing Workflow

Constraints / Bottlenecks

Process mapping also assists in identifying process constraints or “bottlenecks”

Process Constraint = Area where demand is greater than the current ability to supply

More on this later!

Page 23: Optimizing Sterile Processing Workflow

Step 2: Improving Functions and Workflow Optimizing Workflow

Streamline Identify Waste Work Process Simplification Capacity Line Balancing

Page 24: Optimizing Sterile Processing Workflow

Streamline

Eliminating and minimizing non-value added steps in the process

Quick hits to produce quick results Not all non-value added can or should be

eliminated

Page 25: Optimizing Sterile Processing Workflow

Identify Waste

Labor Waste Quality inspections after the set is complete

versus IT solutions and certification to ensure proper set preparation the first time

Time spent looking for an item that should be readily available

Improperly staffed SPD or other reprocessing areas

Page 26: Optimizing Sterile Processing Workflow

Identify Waste

Overproduction Excessive stat washes or flash sterilization in

the OR when instrument set is not used for an immediate procedure

Space Non-linear workflow from requiring storage

racks and transportation routes Excessive movements, poor ergonomics Non-reprocessing supplies stored in

reprocessing work areas

Page 27: Optimizing Sterile Processing Workflow

Identify Waste

Defects Sets put up with missing instruments, extra

instruments, or wrong instruments Improper Count Sheets or documentation Instruments not returned to decontamination in

their original container/tray Sets returned with instruments missing

Page 28: Optimizing Sterile Processing Workflow

Identify Waste

Time Work schedules that do not align with

workload requirements (too many technicians too early in the day as an example)

Assembly staff waiting for instruments from decontamination

Instruments arriving from the OR with extra items, missing items, or non-instrument items that slow down decontamination process

Page 29: Optimizing Sterile Processing Workflow

Work Process Simplification

Deep dive into detailed process steps Increase process utilization and capacity Develop smooth flow of materials, work and

communication Eliminate

Unnecessary work Rework Fatiguing motions Long transports and complicated paperwork

Page 30: Optimizing Sterile Processing Workflow

Work Process Simplification

Prioritize Select activity that benefits the entire process Select activity that a lot of time is currently

spent on - greater benefit than smaller tasks Select activities that currently require a lot of

chasing or looking for items, hard work, inspections, or non-desirable work conditions

Page 31: Optimizing Sterile Processing Workflow

Work Process Simplification

Prioritize – Instrument Assembly example Provide all needed materials within the

technician’s reach Eliminate unnecessary materials from

instrument sets Remove unneeded instruments from set to

reduce the set size and simply the assembly Provide accurate count sheets, IT solutions, or

pictures to assist in the assembly process

Page 32: Optimizing Sterile Processing Workflow

Work Process Simplification Steps

Keep an open mind and no work process can be taken for granted – question everything!

1. Select the job or function to be improved 2. Process chart the job in detail

All operational steps Transportations Inspections Storage Delays Time and Distance

Work Process Simplification Steps

3. Question each detail 4. Develop a new method

Reduce the number of steps Arrange the steps in the best order Make the steps as efficient as possible Reduce handling Combine steps Shorten moves Provide the most economical method

Page 35: Optimizing Sterile Processing Workflow

Work Process Simplification Steps

5. Implement the new process 6. Review, measure, and repeat

Page 36: Optimizing Sterile Processing Workflow

Work Process Simplification Steps

Sample Instrument Assembly Are instruments brought to the assembler? Are extra instruments readily available to

replace missing? Are all needed materials within reach? Is the walking and transporting minimized? Can sets assembled per hour be increased? Can time to assemble each set be decreased? Are clear procedures available to handle non-

conforming situations?

Page 39: Optimizing Sterile Processing Workflow

Capacity Line Balancing

Capacity: The amount of work a person, equipment, or process is capable or producing during a given amount of time

Capacity Requirement: The amount of work a person, equipment, or process is required to produce during a given amount of time

Capacity Line Balancing: Matching the capacity of each operation within a process to the requirements of the next

Page 40: Optimizing Sterile Processing Workflow

Capacity Line Balancing

Optimize the capacity of the entire process! First, perform a Capacity Analysis

Determine customer workload – often considered OR soiled instruments entering decontamination

Establish the arrival pattern or timing of workload

Utilize cycle times and work standards Determine needed resources to provide the

required capacity to handle the workload

Capacity Line Balancing

Second, balance the capacity Identify the capacity restraint or “bottleneck” Ensure that the bottleneck operation is

properly scheduled and staffed to handle the reprocessing workload that is coming into it

Ensure that the operation and it’s equipment is functioning at it’s peak performance

Acquire additional pieces of equipment or staff to meet demand

Step 3: Workstation and Operations Sequence Layout Linear flow for operational efficiencies but

also necessary to separate soiled, clean, and sterile items

All necessary and frequently used items are available within arm’s reach

Properly designed seating, fatigue mats, and ergonomically workstations

Page 45: Optimizing Sterile Processing Workflow

Step 4: Standardize Work Practices

Determine best practice and standardize to it Involve the people doing the work Document practice in procedures and work

instructions Train, train, and train Follow-up to ensure compliance Encourage continuous improvement and

change

Page 46: Optimizing Sterile Processing Workflow

Step 5: Scheduling Process

Ensure the sequence of CS operations are logical and easily understood

Schedule people, equipment, and processes to ensure smooth flow without interruptions or delays

Schedule to support the capacity line balancing except for the “push” of decontamination

Page 47: Optimizing Sterile Processing Workflow

Step 5: Scheduling Process

Push: Decontamination should “push”

instrumentation as quickly as possible to assembly without regard to capacity balancing

“Push” ensures instruments are quickly cleaned and identified as being in CS

Pull: Assembly and sterilization can then “pull” the

instrumentation through according to capacity restraints and customer requirements

Page 48: Optimizing Sterile Processing Workflow

Step 6: Measuring Process Performance Measure what you value Differentiate between perception and reality Measure based on facts Identifies process issues and bottlenecks Evaluates customer satisfaction level Provide a baseline to monitor improvement

Page 49: Optimizing Sterile Processing Workflow

Measuring Process Performance

Two purposes for developing consistent metrics and measurements within CS Ensure performance meets expectations while

driving accountability To measure the impact of any improvement

while driving additional improvement efforts

Page 50: Optimizing Sterile Processing Workflow

Measuring Process Performance

All measurements require a “goal” Sustainable goals reflect current process

performance such as hitting your budget Stretch goals focus people on changing the

process rather than tweaking the existing one

Page 51: Optimizing Sterile Processing Workflow

Measuring Process Performance

“We can’t change what we don’t measure.”

“Don’t measure what you won’t change.”

Focus your measurements on what you value and what you want to improve.

Page 52: Optimizing Sterile Processing Workflow

Measuring Process Performance

Track, post, discuss, and take action based on the performance factors being measured

Timeliness of measurement and feedback is of utmost importance

Employees should have a clear understanding of what the customer and management expects of them for every task they perform – both quality and productivity

Page 53: Optimizing Sterile Processing Workflow

Measuring Process Performance

Key CS measurements Quality: Defects per total items produced Customer Experience: Positive experiences

per total experiences CS Labor Hours per Procedure Productivity Skill mix and competency

Page 54: Optimizing Sterile Processing Workflow

Step 7: Active Management / Supervisory Techniques Communication

Continuous cycle Effective assignment giving and follow-up Regular interaction to ensure processes are

being followed Leads to problem identification and resolution Nothing in the process or work practices

should be taken for granted

Page 55: Optimizing Sterile Processing Workflow

Active Management / Supervisory Techniques Problem Resolution and Documentation “If it isn’t written – it isn’t done.” Use an Action Item tool or at least a simple

To-Do list.

Page 56: Optimizing Sterile Processing Workflow

Summary

It Doesn’t Take A Crisis – But It Helps… Change is usually a response to negative

circumstances – but this doesn’t have to be the reason

Start today by mapping and understanding your process and identifying your first opportunity for improvement
