Root Cause Analysis Finding the underlying cause © 2011 Jones and Bartlett Publishers, LLC
What is RCA? • The ultimate detective work – finding the cause of an “error” • Structured method of finding an underlying problem or series of problems • Occurs after an error has occurred • Principles: – Directing improvement efforts at the underlying causes of a process problem is more effective than simply trying to correct the erroneous process output. – Effective RCA is methodical and reproducible. Following a set procedure for RCA produces the best results. – Typically, defects and errors have more than one underlying cause, i. e. a defective process rarely has just one problematic process step. – For the analysis and resulting interventions to be effective, the RCA must establish all root causes so that effective improvement initiatives may be generated. © 2011 Jones and Bartlett Publishers, LLC
RCA Procedure • Define the problem using RCA tools and by gathering and analyzing process data. • Use the “ 5 Whys” to identify causal relationships associated with the defined problem(s). • Brainstorm which causes can be removed to prevent recurrence. • Design solutions and associated measures to remedy the underlying causes. © 2011 Jones and Bartlett Publishers, LLC
• Pilot test these solutions and measures to evaluate the effects may help determine the priority for implementing each solution. Use the SMART criteria: – Simple – easy to design and put into service. – Measurable – capable of being measured to determine effectiveness – Attainable – achievable by the team and resources available. – Relevant – directed at the specific problem identified by the team. – Timely – achievable within the allotted timeframe. © 2011 Jones and Bartlett Publishers, LLC
RCA Procedure (cont. ) • Determine the sequence of implementation of the solutions, including the time for each improvement step to be applied. – Stage repairs to minimize costs – Implement stepwise to understand the effect of each solution – Serious errors may need rapid implementation of solutions • Measure the effects of the changes to ensure that the changes have produced the expected results. © 2011 Jones and Bartlett Publishers, LLC
The 5 Whys • Question-asking method used to ascertain the cause/effect relationships underlying a particular problem. • Based on the assumption that asking “why” up to five times usually gets to the root cause of a problem • Try it with a problem like “my car won’t run” © 2011 Jones and Bartlett Publishers, LLC
Pareto analysis • Narrow an extensive list of possibilities to those that have the greatest effect on the desired variable based on the Pareto principle (80 -20 rule – 80% of problems come from 20% of causes) • Procedure – Each underlying cause is assigned an estimate of its effects on the final outcome – Estimates are graphed in sequence until 80% of the effect is determined © 2011 Jones and Bartlett Publishers, LLC
Pareto Chart Example 2. 1 © 2011 Jones and Bartlett Publishers, LLC
Ishikawa Diagram • Root Cause Analysis – Cause and effect relationships – Many causes are related – Ishikawa allows aggregation of causes – Relationships are grouped in fishbone configuration • Procedure – Define problem – Have team work on list of root causes – Group causes – Create branching diagram – Continue analysis until all branches have been defined • Note – can be done in Visio © 2011 Jones and Bartlett Publishers, LLC

Fault tree analysis • Failure analysis using Boolean (ifthen-else) logic to determine the probability of a safety hazard • FTA diagrams are commonly used to illustrate events that might lead to a failure © 2011 Jones and Bartlett Publishers, LLC
• Targeted for prevention • Often applied during analysis phase of 6 s DMAIC • Analysis begins by defining top event (or failure), then using event and gate shapes to illustrate the process that might lead to the failure © 2011 Jones and Bartlett Publishers, LLC
Barrier analysis • Used to prevent harm to vulnerable or valuable objects (e. g. patients, staff, organizational reputation, or the wider community) • For RCA, the approach determines what barriers or controls should have been in place to prevent the incident, or that could be installed to increase system safety • Four types of barriers: – Physical – examples include bar coding for medications, keypad controlled doors for computer security, automated drug dispensing units. – Natural –barriers of distance, time, or location, e. g. spacing drug doses apart by several hours to prevent an adverse interaction, or surgical time out to ensure that all patient information is correct. – Human action – e. g. nurse checking the temperature of the water used to bathe a newborn in the nursery, physician using a checklist – Administrative – protocols and procedures for hospital processes, supervision requirements for new nurses, The Joint Commission’s Ongoing Professional Practice Evaluation (OPPE) program. © 2011 Jones and Bartlett Publishers, LLC
Change analysis • Compares an error free instance of a process with the situation in which the process created an error • Example: – RCA team might compare the process used during a surgical procedure that created an error with the process used for the same procedure at a different time that did not produce the error – Differences in the two situations can help identify the changes in the process that led to the nonconforming outcome © 2011 Jones and Bartlett Publishers, LLC

Automated methods • Example: Tap. Root® software • www. taproot. com © 2011 Jones and Bartlett Publishers, LLC
Is-Is Not (Kepner-Tregoe) • Associates reality with desire for problems in a process • Relates to four W’s and an H • Procedure – Characterize the problem in understandable terms – Formulate entries in matrix using idea generating techniques – Patterns usually emerge as matrix is completed © 2011 Jones and Bartlett Publishers, LLC
Is-Is Not Matrix Example IS - what actually happens now IS NOT - what should happen, but doesn't Variations - what seems unusual about the situation Who s involved in the i process or problem? What inputs or outputs are involved in the problem or process? When oes the problem d occur? In what portion of the process? Where does the problem occur? In what part of the organization or what location? How important is the problem to the process? How extensive is the problem? © 2011 Jones and Bartlett Publishers, LLC
Failure Mode and Effects Analysis “RCA in reverse” © 2011 Jones and Bartlett Publishers, LLC
Widely used in health care • Preventive method used to investigate potential process failures prospectively • Also known as FMECA – Failure Mode and Effects Criticality Analysis • Veteran’s Health Administration was pioneer in applying FMECA in health care • Joint Commission began requiring use of FMEA as an accreditation standard (LD 3. 20) in 2002, caused wide adoption of the approach © 2011 Jones and Bartlett Publishers, LLC
FMECA - procedure • Choose a target process – Example: process associated with high risk of patient harm – Executive team input important – Tools - four quadrant importance/performance matrix that relates risk (importance) to performance metrics • Assemble Team – multidisciplinary teams, since failure modes often cross functional areas. Subject matter experts are often helpful, as is a senior executive who can ensure that the FMEA procedure has necessary resources. • Flowchart the process © 2011 Jones and Bartlett Publishers, LLC
FMECA – procedure (cont. ) • Perform a hazard analysis – Identify and number failure modes – Determine the cause and effect of each failure mode and record in a matrix – Score each failure mode on three factors using a 10 point scale: the likelihood of the failure mode, the likelihood that the failure mode will be detected by the process owners, and the severity of the effect – Calculate Risk Priority Number (RPN) from these three numbers - the higher the RPN, the greater the risk (equation in book) – Rank RPNs to determine priorities • Determine action steps and measures – Business case analysis © 2011 Jones and Bartlett Publishers, LLC
