Root Cause Analysis and patient safety,
        Why is it important ?

Today’s health-care context is highly complex. Care is often
delivered in a pressurized and fast-moving environment, involving a
vast array of technology and, daily, many individual decisions and
judgements by health-care professional staff. In such circumstances
things can and do go wrong. Sometimes unintentional harm comes
to a patient during a clinical
procedure or as a result of a clinical decision. Errors in the process
of care can result in injury. Sometimes the harm that patients
experience is serious and sometimes people die. (World Health
Organisation-World Alliance for Patient Safety)
   The Patient Safety Agenda
Organisation with a Memory (June 2000)
Even after a decision has been taken to conduct some form of
inquiry or investigation, there is often little by way of consistent
support or expertise available to NHS organisations or to inquiry
teams in the conduct of the process

Building a Safer NHS for Patients (2004)
Described the necessary steps to set up the new national system.
These include building expertise in the NHS in root cause analysis

 7 Steps to Patient Safety (2004)
Guidance to local organisations to ensure that the investigation team they
create is proficient in RCA by providing both online and face-to-face
             Where does RCA fit in?

• RCA is part of a Safety and Quality process.

• It sits alongside incident reporting, patient safety education
  and training and feeds into an organisation’s Risk
  Management Strategy.

• It supports the organization to learn and develop
        What is Root Cause Analysis?
What is a Root Cause?
• The root or fundamental issue, is the earliest point at which action could have
  been taken that would have reduced the chance of the incident happening.

What is Root Cause Analysis?
• Structured process using recognised analytical methods

• Enables you to ask the questions “How” and “Why” in an objective way to
  reveal all the causal factors that have led to a patient safety incident.

• Should be used to prevent similar incidents happening again, not to apply
            Root Cause Analysis
    To be thorough RCA must involve a complete
    review of all possible antecedent events and
•   Look at human behaviour
•   Look at processes and systems
•   Consider all the key players
•   Need to understand what went wrong, how it
    went wrong and how it could be done
            Root Cause Analysis
To be credible a root cause analysis must:
• Be closely supported by the leadership of the
• Involve those closely associated with the processes
  and systems and the outcomes.
• Be applied consistently and transparently according
  to organisational policy/procedure
• Include consideration of relevant literature ie what is
  best practice? What processes and systems function
             Root Cause Analysis

To be effective a root cause analysis must :
• Include development of actions aimed at improving processes
   and systems;
• Ensure there is agreement as to how those improvements will
   be monitored and evaluated
• Be well documented (including all the activity from the point
   of identification to the process of evaluation).
• Engage those involved in the original incident
• Gain the support of those who can make the changes
           Human Error is Inevitable
–   Two approaches to the problem of
    human fallibility exist: the person and
    the system approaches
–   The person approach focuses on the
    errors of individuals, blaming them for
    forgetfulness, inattention, or moral
–   The system approach concentrates on
    the conditions under which individuals
    work and tries to build defences to avert
    errors or mitigate their effects
–   High reliability organisations which have
    less than their fair share of accidents
    recognise that human variability is a
    force to harness in averting errors, but
    they work hard to focus that variability
    and are constantly preoccupied with the
    possibility of failure
         Two Views On Human Error
            Old View                   New View
•   Human error is a cause of   • Error is a symptom of
    accidents                     deeper trouble
•   To explain failure, you
                                • To explain failure, look
    must seek human failure
                                  for the system failure
•   Find people’s incorrect
    assessments, wrong          • Explore how actions and
    decisions, bad judgments      assessments made
•   Get rid of ‘bad apples’       sense at time
    replace with new            • Replacing people leaves
    personnel                     problems in place
                     Error Types                                   Violations involve deliberate deviations from
                                                                   some regulated code of practice or procedure,
                                                                   Reason (1993). They occur because people

                                                                   Familiar situation-wrong
                                    deliberate deviations from a
                                    protocol or code of conduct

These errors occur when people do not
have appropriate, or sufficient, information
upon which to base their decisions or plans

Can you think of one instance where you have

1.A Violation
2.A Mistake
3.A lapse
4.A slip
   Human errors occur because of:

       Inattention
       Memory lapse
       Failure to communicate
       Poorly designed equipment
       Exhaustion
       Ignorance
       Noisy working conditions
       A number of other personal and
        environmental factors
           Systems approach

• “The systems approach is not about changing
  the human condition but rather the conditions
  under which humans work”.

         Process for RCAs
• STEP 1: Agree facts of event

• STEP 2: Establish causality

• STEP 3: Produce Action Plans
The Jack and Jill story
                     Step 1
Identify what happened and antecedents

•   How far back do you go?
•   Who do you involve/question?
•   How much detail do you need?
•   Where are all your sources of information?
•   How much time do you have?
RCA - Gathering the information

•   Incident report       • Photographs
•   Health records        • Staff rotas
•   Policies              • Risk assessments
•   Equipment&            • Training records
    maintenance records   • Witness accounts
                          • Interviews
•   Audit data
  RCA -Telling the story : Helpful tools
    Tracks chronological chain of events.
    Allows the team to identify information
    gaps as well as problems in the process
    of care delivery.

   Step 2- Establish causality

•Analysis focuses on systems and processes and the way
individuals interact with them,
•Analysis starts with apparent or primary causes and
progresses to identification of system vulnerabilities (root
causes and contributing factors)
•Analysis repeatedly digs deeper by asking “why” questions
until no additional logical answer can be identified
•Analysis identifies changes that could be made in systems
and processes to reduce the risk of a similar event occurring
         Step 2: Causality
• Determine pertinent areas

• Focus on pertinent areas

• Formulate causal statements
How would you classify the severity of this

Who would you want/expect to investigate
this case?

What is the extent of your investigation?

The Action Plan
        Key principles of
        solution creation
 Design tasks and processes that minimise
  dependency on short term memory, attention
  span & avoid fatigue
 Simplify task, processes and so on
 Standardise processes & equipment
 Use tools and checklists wisely
 Make it easier to do the right thing!
    Process Redesign Solutions
Make mistakes impossible
– Auto-shut off heating devices
– Circuit breakers
– Ready-to-administer medications
– Write-over protected computer disks

–   Can you think of other mistake-proofing techniques?

Remember redesign means new Risks. Solving a problem in one
  area may create a new problem in another
                     SEA/RCA – REPORT FORMAT

                           WHAT HAPPENED?

 (Including the role of all individuals directly and indirectly involved, the
setting for the event, and any impact or potential impact of the event that
         is relevant to patient care or the conduct of the practice)

                          WHY DID IT HAPPEN?

(Including description and discussion of the main and underlying reasons
              for the event occurring, where this is possible)

                     WHAT HAVE YOU LEARNED?

 (Reflect on significant event and highlight personal and, if appropriate,
                           team-based learning)

                   WHAT CHANGES WILL YOU MAKE?
(What action will be taken, where this is relevant or feasible, ensuring that
 all relevant individuals are involved, how will you monitor the changes)
          Report Preparation
• Cause and effect relationships must be
• Don’t overstate, understate, or
  emotionalize report. It may show up in
• Negative descriptors may not be used
  – “poorly”, “inadequate”, “unsafe”, “unreliable”,
    and “complacency” among many others
              RCA Summary

•   Gather the facts.
•   Determine sequence of events.
•   Identify contributing factors.
•   Select root causes.
•   Develop corrective actions & follow-up plan.
And finally…a good RCA is one that …

• Identifies all the contributory causes
• Leads to more robust systems and processes
• Addresses all key emergent issues not just root
• Shares effective ways to reduce the chances of
  similar mishaps recurring elsewhere within or
  without the organisation and /or shares examples
  of good practice
